+## ClickHouse release 21.5, 2021-05-20
+
+#### Backward Incompatible Change
+
+* Change comparison of integers and floating point numbers when integer is not exactly representable in the floating point data type. In new version comparison will return false as the rounding error will occur. Example: `9223372036854775808.0 != 9223372036854775808`, because the number `9223372036854775808` is not representable as floating point number exactly (and `9223372036854775808.0` is rounded to `9223372036854776000.0`). But in previous version the comparison will return as the numbers are equal, because if the floating point number `9223372036854776000.0` get converted back to UInt64, it will yield `9223372036854775808`. For the reference, the Python programming language also treats these numbers as equal. But this behaviour was dependend on CPU model (different results on AMD64 and AArch64 for some out-of-range numbers), so we make the comparison more precise. It will treat int and float numbers equal only if int is represented in floating point type exactly. [#22595](https://github.com/ClickHouse/ClickHouse/pull/22595) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Remove support for `argMin` and `argMax` for single `Tuple` argument. The code was not memory-safe. The feature was added by mistake and it is confusing for people. These functions can be reintroduced under different names later. This fixes [#22384](https://github.com/ClickHouse/ClickHouse/issues/22384) and reverts [#17359](https://github.com/ClickHouse/ClickHouse/issues/17359). [#23393](https://github.com/ClickHouse/ClickHouse/pull/23393) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+
+* Added functions `dictGetChildren(dictionary, key)`, `dictGetDescendants(dictionary, key, level)`. Function `dictGetChildren` return all children as an array if indexes. It is a inverse transformation for `dictGetHierarchy`. Function `dictGetDescendants` return all descendants as if `dictGetChildren` was applied `level` times recursively. Zero `level` value is equivalent to infinity. Improved performance of `dictGetHierarchy`, `dictIsIn` functions. Closes [#14656](https://github.com/ClickHouse/ClickHouse/issues/14656). [#22096](https://github.com/ClickHouse/ClickHouse/pull/22096) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added function `dictGetOrNull`. It works like `dictGet`, but return `Null` in case key was not found in dictionary. Closes [#22375](https://github.com/ClickHouse/ClickHouse/issues/22375). [#22413](https://github.com/ClickHouse/ClickHouse/pull/22413) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added a table function `s3Cluster`, which allows to process files from `s3` in parallel on every node of a specified cluster. [#22012](https://github.com/ClickHouse/ClickHouse/pull/22012) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Added support for replicas and shards in MySQL/PostgreSQL table engine / table function. You can write `SELECT * FROM mysql('host{1,2}-{1|2}', ...)`. Closes [#20969](https://github.com/ClickHouse/ClickHouse/issues/20969). [#22217](https://github.com/ClickHouse/ClickHouse/pull/22217) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Added `ALTER TABLE ... FETCH PART ...` query. It's similar to `FETCH PARTITION`, but fetches only one part. [#22706](https://github.com/ClickHouse/ClickHouse/pull/22706) ([turbo jason](https://github.com/songenjie)).
+* Added a setting `max_distributed_depth` that limits the depth of recursive queries to `Distributed` tables. Closes [#20229](https://github.com/ClickHouse/ClickHouse/issues/20229). [#21942](https://github.com/ClickHouse/ClickHouse/pull/21942) ([flynn](https://github.com/ucasFL)).
+
+#### Performance Improvement
+
+* Improved performance of `intDiv` by dynamic dispatch for AVX2. This closes [#22314](https://github.com/ClickHouse/ClickHouse/issues/22314). [#23000](https://github.com/ClickHouse/ClickHouse/pull/23000) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Improved performance of reading from `ArrowStream` input format for sources other then local file (e.g. URL). [#22673](https://github.com/ClickHouse/ClickHouse/pull/22673) ([nvartolomei](https://github.com/nvartolomei)).
+* Disabled compression by default when interacting with localhost (with clickhouse-client or server to server with distributed queries) via native protocol. It may improve performance of some import/export operations. This closes [#22234](https://github.com/ClickHouse/ClickHouse/issues/22234). [#22237](https://github.com/ClickHouse/ClickHouse/pull/22237) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Exclude values that does not belong to the shard from right part of IN section for distributed queries (under `optimize_skip_unused_shards_rewrite_in`, enabled by default, since it still requires `optimize_skip_unused_shards`). [#21511](https://github.com/ClickHouse/ClickHouse/pull/21511) ([Azat Khuzhin](https://github.com/azat)).
+* Improved performance of reading a subset of columns with File-like table engine and column-oriented format like Parquet, Arrow or ORC. This closes [#issue:20129](https://github.com/ClickHouse/ClickHouse/issues/20129). [#21302](https://github.com/ClickHouse/ClickHouse/pull/21302) ([keenwolf](https://github.com/keen-wolf)).
+* Allow to move more conditions to `PREWHERE` as it was before version 21.1 (adjustment of internal heuristics). Insufficient number of moved condtions could lead to worse performance. [#23397](https://github.com/ClickHouse/ClickHouse/pull/23397) ([Anton Popov](https://github.com/CurtizJ)).
+* Improved performance of ODBC connections and fixed all the outstanding issues from the backlog. Using `nanodbc` library instead of `Poco::ODBC`. Closes [#9678](https://github.com/ClickHouse/ClickHouse/issues/9678). Add support for DateTime64 and Decimal* for ODBC table engine. Closes [#21961](https://github.com/ClickHouse/ClickHouse/issues/21961). Fixed issue with cyrillic text being truncated. Closes [#16246](https://github.com/ClickHouse/ClickHouse/issues/16246). Added connection pools for odbc bridge. [#21972](https://github.com/ClickHouse/ClickHouse/pull/21972) ([Kseniia Sumarokova](https://github.com/kssenii)).
+
+#### Improvement
+
+* Increase `max_uri_size` (the maximum size of URL in HTTP interface) to 1 MiB by default. This closes [#21197](https://github.com/ClickHouse/ClickHouse/issues/21197). [#22997](https://github.com/ClickHouse/ClickHouse/pull/22997) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Set `background_fetches_pool_size` to `8` that is better for production usage with frequent small insertions or slow ZooKeeper cluster. [#22945](https://github.com/ClickHouse/ClickHouse/pull/22945) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* FlatDictionary added `initial_array_size`, `max_array_size` options. [#22521](https://github.com/ClickHouse/ClickHouse/pull/22521) ([Maksim Kita](https://github.com/kitaisreal)).
+* Add new setting `non_replicated_deduplication_window` for non-replicated MergeTree inserts deduplication. [#22514](https://github.com/ClickHouse/ClickHouse/pull/22514) ([alesapin](https://github.com/alesapin)).
+* Update paths to the `CatBoost` model configs in config reloading. [#22434](https://github.com/ClickHouse/ClickHouse/pull/22434) ([Kruglov Pavel](https://github.com/Avogar)).
+* Added `Decimal256` type support in dictionaries. `Decimal256` is experimental feature. Closes [#20979](https://github.com/ClickHouse/ClickHouse/issues/20979). [#22960](https://github.com/ClickHouse/ClickHouse/pull/22960) ([Maksim Kita](https://github.com/kitaisreal)).
+* Enabled `async_socket_for_remote` by default (using less amount of OS threads for distributed queries). [#23683](https://github.com/ClickHouse/ClickHouse/pull/23683) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Fixed `quantile(s)TDigest`. Added special handling of singleton centroids according to tdunning/t-digest 3.2+. Also a bug with over-compression of centroids in implementation of earlier version of the algorithm was fixed. [#23314](https://github.com/ClickHouse/ClickHouse/pull/23314) ([Vladimir Chebotarev](https://github.com/excitoon)).
+* Make function name `unhex` case insensitive for compatibility with MySQL. [#23229](https://github.com/ClickHouse/ClickHouse/pull/23229) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Implement functions `arrayHasAny`, `arrayHasAll`, `has`, `indexOf`, `countEqual` for generic case when types of array elements are different. In previous versions the functions `arrayHasAny`, `arrayHasAll` returned false and `has`, `indexOf`, `countEqual` thrown exception. Also add support for `Decimal` and big integer types in functions `has` and similar. This closes [#20272](https://github.com/ClickHouse/ClickHouse/issues/20272). [#23044](https://github.com/ClickHouse/ClickHouse/pull/23044) ([alexey-milovidov](https://github.com/alexey-milovidov)).

+* Added ability to run clickhouse-keeper (experimental drop-in replacement to ZooKeeper) with SSL. Config settings `keeper_server.tcp_port_secure` can be used for secure interaction between client and keeper-server. `keeper_server.raft_configuration.secure` can be used to enable internal secure communication between nodes. [#22992](https://github.com/ClickHouse/ClickHouse/pull/22992) ([alesapin](https://github.com/alesapin)).
+* Added ability to flush buffer only in background for `Buffer` tables. [#22986](https://github.com/ClickHouse/ClickHouse/pull/22986) ([Azat Khuzhin](https://github.com/azat)).
+* When selecting from MergeTree table with NULL in WHERE condition, in rare cases, exception was thrown. This closes [#20019](https://github.com/ClickHouse/ClickHouse/issues/20019).

+* `dateDiff` now works with `DateTime64` arguments (even for values outside of `DateTime` range) [#22931](https://github.com/ClickHouse/ClickHouse/pull/22931) ([Vasily Nemkov](https://github.com/Enmk)).
+* MaterializeMySQL (experimental feature): added an ability to replicate MySQL databases containing views without failing. This is accomplished by ignoring the views. [#22760](https://github.com/ClickHouse/ClickHouse/pull/22760) ([Christian](https://github.com/cfroystad)).
+* Allow RBAC row policy via postgresql protocol. Closes [#22658](https://github.com/ClickHouse/ClickHouse/issues/22658). PostgreSQL protocol is enabled in configuration by default. [#22755](https://github.com/ClickHouse/ClickHouse/pull/22755) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add metric to track how much time is spend during waiting for Buffer layer lock. [#22725](https://github.com/ClickHouse/ClickHouse/pull/22725) ([Azat Khuzhin](https://github.com/azat)).

+
+#### Build/Testing/Packaging Improvement
+
+* Run stateless tests in parallel in CI. [#22300](https://github.com/ClickHouse/ClickHouse/pull/22300) ([alesapin](https://github.com/alesapin)).
+* Simplify debian packages. This fixes [#21698](https://github.com/ClickHouse/ClickHouse/issues/21698). [#22976](https://github.com/ClickHouse/ClickHouse/pull/22976) ([alexey-milovidov](https://github.com/alexey-milovidov)).

+* Fixed some tests on AArch64 platform. [#22596](https://github.com/ClickHouse/ClickHouse/pull/22596) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Added function alignment for possibly better performance. [#21431](https://github.com/ClickHouse/ClickHouse/pull/21431) ([Danila Kutenin](https://github.com/danlark1)).
+* Adjust some tests to output identical results on amd64 and aarch64 (qemu). The result was depending on implementation specific CPU behaviour. [#22590](https://github.com/ClickHouse/ClickHouse/pull/22590) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Allow query profiling only on x86_64. See [#15174](https://github.com/ClickHouse/ClickHouse/issues/15174#issuecomment-812954965) and [#15638](https://github.com/ClickHouse/ClickHouse/issues/15638#issuecomment-703805337). This closes [#15638](https://github.com/ClickHouse/ClickHouse/issues/15638). [#22580](https://github.com/ClickHouse/ClickHouse/pull/22580) ([alexey-milovidov](https://github.com/alexey-milovidov)).

+* Enable bundled `openldap` on `ppc64le` [#22487](https://github.com/ClickHouse/ClickHouse/pull/22487) ([Kfir Itzhak](https://github.com/mastertheknife)).
+* Disable incompatible libraries (platform specific typically) on `ppc64le` [#22475](https://github.com/ClickHouse/ClickHouse/pull/22475) ([Kfir Itzhak](https://github.com/mastertheknife)).
+* Add Jepsen test in CI for clickhouse Keeper. [#22373](https://github.com/ClickHouse/ClickHouse/pull/22373) ([alesapin](https://github.com/alesapin)).

+
+## ClickHouse release 21.4
+
+### ClickHouse release 21.4.1 2021-04-12
+
+#### Backward Incompatible Change
+
+* The `toStartOfIntervalFunction` will align hour intervals to the midnight (in previous versions they were aligned to the start of unix epoch). For example, `toStartOfInterval(x, INTERVAL 11 HOUR)` will split every day into three intervals: `00:00:00..10:59:59`, `11:00:00..21:59:59` and `22:00:00..23:59:59`. This behaviour is more suited for practical needs. This closes [#9510](https://github.com/ClickHouse/ClickHouse/issues/9510). [#22060](https://github.com/ClickHouse/ClickHouse/pull/22060) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* `Age` and `Precision` in graphite rollup configs should increase from retention to retention. Now it's checked and the wrong config raises an exception. [#21496](https://github.com/ClickHouse/ClickHouse/pull/21496) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Fix `cutToFirstSignificantSubdomainCustom()`/`firstSignificantSubdomainCustom()` returning wrong result for 3+ level domains present in custom top-level domain list. For input domains matching these custom top-level domains, the third-level domain was considered to be the first significant one. This is now fixed. This change may introduce incompatibility if the function is used in e.g. the sharding key. [#21946](https://github.com/ClickHouse/ClickHouse/pull/21946) ([Azat Khuzhin](https://github.com/azat)).
+* Column `keys` in table `system.dictionaries` was replaced to columns `key.names` and `key.types`. Columns `key.names`, `key.types`, `attribute.names`, `attribute.types` from `system.dictionaries` table does not require dictionary to be loaded. [#21884](https://github.com/ClickHouse/ClickHouse/pull/21884) ([Maksim Kita](https://github.com/kitaisreal)).
+* Now replicas that are processing the `ALTER TABLE ATTACH PART[ITION]` command search in their `detached/` folders before fetching the data from other replicas. As an implementation detail, a new command `ATTACH_PART` is introduced in the replicated log. Parts are searched and compared by their checksums. [#18978](https://github.com/ClickHouse/ClickHouse/pull/18978) ([Mike Kot](https://github.com/myrrc)). **Note**:
+  * `ATTACH PART[ITION]` queries may not work during cluster upgrade.
+  * It's not possible to rollback to older ClickHouse version after executing `ALTER ... ATTACH` query in new version as the old servers would fail to pass the `ATTACH_PART` entry in the replicated log.
+* In this version, empty `<remote_url_allow_hosts></remote_url_allow_hosts>` will block all access to remote hosts while in previous versions it did nothing. If you want to keep old behaviour and you have empty `remote_url_allow_hosts` element in configuration file, remove it. [#20058](https://github.com/ClickHouse/ClickHouse/pull/20058) ([Vladimir Chebotarev](https://github.com/excitoon)).
+
+
+#### New Feature
+
+* Extended range of `DateTime64` to support dates from year 1925 to 2283. Improved support of `DateTime` around zero date (`1970-01-01`). [#9404](https://github.com/ClickHouse/ClickHouse/pull/9404) ([alexey-milovidov](https://github.com/alexey-milovidov), [Vasily Nemkov](https://github.com/Enmk)). Not every time and date functions are working for extended range of dates.
+* Added support of Kerberos authentication for preconfigured users and HTTP requests (GSS-SPNEGO). [#14995](https://github.com/ClickHouse/ClickHouse/pull/14995) ([Denis Glazachev](https://github.com/traceon)).
+* Add `prefer_column_name_to_alias` setting to use original column names instead of aliases. it is needed to be more compatible with common databases' aliasing rules. This is for [#9715](https://github.com/ClickHouse/ClickHouse/issues/9715) and [#9887](https://github.com/ClickHouse/ClickHouse/issues/9887). [#22044](https://github.com/ClickHouse/ClickHouse/pull/22044) ([Amos Bird](https://github.com/amosbird)).
+* Added functions `dictGetChildren(dictionary, key)`, `dictGetDescendants(dictionary, key, level)`. Function `dictGetChildren` return all children as an array if indexes. It is a inverse transformation for `dictGetHierarchy`. Function `dictGetDescendants` return all descendants as if `dictGetChildren` was applied `level` times recursively. Zero `level` value is equivalent to infinity. Closes [#14656](https://github.com/ClickHouse/ClickHouse/issues/14656). [#22096](https://github.com/ClickHouse/ClickHouse/pull/22096) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added `executable_pool` dictionary source. Close [#14528](https://github.com/ClickHouse/ClickHouse/issues/14528). [#21321](https://github.com/ClickHouse/ClickHouse/pull/21321) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added table function `dictionary`. It works the same way as `Dictionary` engine. Closes [#21560](https://github.com/ClickHouse/ClickHouse/issues/21560). [#21910](https://github.com/ClickHouse/ClickHouse/pull/21910) ([Maksim Kita](https://github.com/kitaisreal)).
+* Support `Nullable` type for `PolygonDictionary` attribute. [#21890](https://github.com/ClickHouse/ClickHouse/pull/21890) ([Maksim Kita](https://github.com/kitaisreal)).
+* Functions `dictGet`, `dictHas` use current database name if it is not specified for dictionaries created with DDL. Closes [#21632](https://github.com/ClickHouse/ClickHouse/issues/21632). [#21859](https://github.com/ClickHouse/ClickHouse/pull/21859) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added function `dictGetOrNull`. It works like `dictGet`, but return `Null` in case key was not found in dictionary. Closes [#22375](https://github.com/ClickHouse/ClickHouse/issues/22375). [#22413](https://github.com/ClickHouse/ClickHouse/pull/22413) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added async update in `ComplexKeyCache`, `SSDCache`, `SSDComplexKeyCache` dictionaries. Added support for `Nullable` type in `Cache`, `ComplexKeyCache`, `SSDCache`, `SSDComplexKeyCache` dictionaries. Added support for multiple attributes fetch with `dictGet`, `dictGetOrDefault` functions. Fixes [#21517](https://github.com/ClickHouse/ClickHouse/issues/21517). [#20595](https://github.com/ClickHouse/ClickHouse/pull/20595) ([Maksim Kita](https://github.com/kitaisreal)).
+* Support `dictHas` function for `RangeHashedDictionary`. Fixes [#6680](https://github.com/ClickHouse/ClickHouse/issues/6680). [#19816](https://github.com/ClickHouse/ClickHouse/pull/19816) ([Maksim Kita](https://github.com/kitaisreal)).
+* Add function `timezoneOf` that returns the timezone name of `DateTime` or `DateTime64` data types. This does not close [#9959](https://github.com/ClickHouse/ClickHouse/issues/9959). Fix inconsistencies in function names: add aliases `timezone` and `timeZone` as well as `toTimezone` and `toTimeZone` and `timezoneOf` and `timeZoneOf`. [#22001](https://github.com/ClickHouse/ClickHouse/pull/22001) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Add new optional clause `GRANTEES` for `CREATE/ALTER USER` commands. It specifies users or roles which are allowed to receive grants from this user on condition this user has also all required access granted with grant option. By default `GRANTEES ANY` is used which means a user with grant option can grant to anyone. Syntax: `CREATE USER ... GRANTEES {user | role | ANY | NONE} [,...] [EXCEPT {user | role} [,...]]`. [#21641](https://github.com/ClickHouse/ClickHouse/pull/21641) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Add new column `slowdowns_count` to `system.clusters`. When using hedged requests, it shows how many times we switched to another replica because this replica was responding slowly. Also show actual value of `errors_count` in `system.clusters`. [#21480](https://github.com/ClickHouse/ClickHouse/pull/21480) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add `_partition_id` virtual column for `MergeTree*` engines. Allow to prune partitions by `_partition_id`. Add `partitionID()` function to calculate partition id string. [#21401](https://github.com/ClickHouse/ClickHouse/pull/21401) ([Amos Bird](https://github.com/amosbird)).
+* Add function `isIPAddressInRange` to test if an IPv4 or IPv6 address is contained in a given CIDR network prefix. [#21329](https://github.com/ClickHouse/ClickHouse/pull/21329) ([PHO](https://github.com/depressed-pho)).
+* Added new SQL command `ALTER TABLE 'table_name' UNFREEZE [PARTITION 'part_expr'] WITH NAME 'backup_name'`. This command is needed to properly remove 'freezed' partitions from all disks. [#21142](https://github.com/ClickHouse/ClickHouse/pull/21142) ([Pavel Kovalenko](https://github.com/Jokser)).
+* Supports implicit key type conversion for JOIN. [#19885](https://github.com/ClickHouse/ClickHouse/pull/19885) ([Vladimir](https://github.com/vdimir)).
+
+#### Experimental Feature
+
+* Support `RANGE OFFSET` frame (for window functions) for floating point types. Implement `lagInFrame`/`leadInFrame` window functions, which are analogous to `lag`/`lead`, but respect the window frame. They are identical when the frame is `between unbounded preceding and unbounded following`. This closes [#5485](https://github.com/ClickHouse/ClickHouse/issues/5485). [#21895](https://github.com/ClickHouse/ClickHouse/pull/21895) ([Alexander Kuzmenkov](https://github.com/akuzm)).
+* Zero-copy replication for `ReplicatedMergeTree` over S3 storage. [#16240](https://github.com/ClickHouse/ClickHouse/pull/16240) ([ianton-ru](https://github.com/ianton-ru)).
+* Added possibility to migrate existing S3 disk to the schema with backup-restore capabilities. [#22070](https://github.com/ClickHouse/ClickHouse/pull/22070) ([Pavel Kovalenko](https://github.com/Jokser)).
+
+#### Performance Improvement
+
+* Supported parallel formatting in `clickhouse-local` and everywhere else. [#21630](https://github.com/ClickHouse/ClickHouse/pull/21630) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Support parallel parsing for `CSVWithNames` and `TSVWithNames` formats. This closes [#21085](https://github.com/ClickHouse/ClickHouse/issues/21085). [#21149](https://github.com/ClickHouse/ClickHouse/pull/21149) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Enable read with mmap IO for file ranges from 64 MiB (the settings `min_bytes_to_use_mmap_io`). It may lead to moderate performance improvement. [#22326](https://github.com/ClickHouse/ClickHouse/pull/22326) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Add cache for files read with `min_bytes_to_use_mmap_io` setting. It makes significant (2x and more) performance improvement when the value of the setting is small by avoiding frequent mmap/munmap calls and the consequent page faults. Note that mmap IO has major drawbacks that makes it less reliable in production (e.g. hung or SIGBUS on faulty disks; less controllable memory usage). Nevertheless it is good in benchmarks. [#22206](https://github.com/ClickHouse/ClickHouse/pull/22206) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Avoid unnecessary data copy when using codec `NONE`. Please note that codec `NONE` is mostly useless - it's recommended to always use compression (`LZ4` is by default). Despite the common belief, disabling compression may not improve performance (the opposite effect is possible). The `NONE` codec is useful in some cases: - when data is uncompressable; - for synthetic benchmarks. [#22145](https://github.com/ClickHouse/ClickHouse/pull/22145) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Faster `GROUP BY` with small `max_rows_to_group_by` and `group_by_overflow_mode='any'`. [#21856](https://github.com/ClickHouse/ClickHouse/pull/21856) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Optimize performance of queries like `SELECT ... FINAL ... WHERE`. Now in queries with `FINAL` it's allowed to move to `PREWHERE` columns, which are in sorting key. [#21830](https://github.com/ClickHouse/ClickHouse/pull/21830) ([foolchi](https://github.com/foolchi)).
+* Improved performance by replacing `memcpy` to another implementation. This closes [#18583](https://github.com/ClickHouse/ClickHouse/issues/18583). [#21520](https://github.com/ClickHouse/ClickHouse/pull/21520) ([alexey-milovidov](https://github.com/alexey-milovidov)).

+* Support non-default table schema for postgres storage/table-function. Closes [#21701](https://github.com/ClickHouse/ClickHouse/issues/21701). [#21711](https://github.com/ClickHouse/ClickHouse/pull/21711) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Support replicas priority for postgres dictionary source. [#21710](https://github.com/ClickHouse/ClickHouse/pull/21710) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Introduce a new merge tree setting `min_bytes_to_rebalance_partition_over_jbod` which allows assigning new parts to different disks of a JBOD volume in a balanced way. [#16481](https://github.com/ClickHouse/ClickHouse/pull/16481) ([Amos Bird](https://github.com/amosbird)).
+* Added `Grant`, `Revoke` and `System` values of `query_kind` column for corresponding queries in `system.query_log`. [#21102](https://github.com/ClickHouse/ClickHouse/pull/21102) ([Vasily Nemkov](https://github.com/Enmk)).
+* Allow customizing timeouts for HTTP connections used for replication independently from other HTTP timeouts. [#20088](https://github.com/ClickHouse/ClickHouse/pull/20088) ([nvartolomei](https://github.com/nvartolomei)).

[#22427](https://github.com/ClickHouse/ClickHouse/pull/22427) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Fix error `Directory tmp_fetch_XXX already exists` which could happen after failed fetch part. Delete temporary fetch directory if it already exists. Fixes [#14197](https://github.com/ClickHouse/ClickHouse/issues/14197). [#22411](https://github.com/ClickHouse/ClickHouse/pull/22411) ([nvartolomei](https://github.com/nvartolomei)).

The expression may also appear due to optimization of something like `SELECT (NULL, NULL) = (8, 0) OR (NULL, NULL) = (3, 2) OR (NULL, NULL) = (0, 0) OR (NULL, NULL) = (3, 1)`. This closes [#22017](https://github.com/ClickHouse/ClickHouse/issues/22017). [#22063](https://github.com/ClickHouse/ClickHouse/pull/22063) ([alexey-milovidov](https://github.com/alexey-milovidov)).

+* If partition key of a `MergeTree` table does not include `Date` or `DateTime` columns but includes exactly one `DateTime64` column, expose its values in the `min_time` and `max_time` columns in `system.parts` and `system.parts_columns` tables. Add `min_time` and `max_time` columns to `system.parts_columns` table (these was inconsistency to the `system.parts` table). This closes [#18244](https://github.com/ClickHouse/ClickHouse/issues/18244). [#22011](https://github.com/ClickHouse/ClickHouse/pull/22011) ([alexey-milovidov](https://github.com/alexey-milovidov)).

+* In rare case, merge for `CollapsingMergeTree` may create granule with `index_granularity + 1` rows. Because of this, internal check, added in [#18928](https://github.com/ClickHouse/ClickHouse/issues/18928) (affects 21.2 and 21.3), may fail with error `Incomplete granules are not allowed while blocks are granules size`.

 * Add experimental `Replicated` database engine. It replicates DDL queries across multiple hosts. [#16193](https://github.com/ClickHouse/ClickHouse/pull/16193) ([tavplubix](https://github.com/tavplubix)).
-* Introduce experimental support for window functions, enabled with `allow_experimental_functions = 1`. This is a preliminary, alpha-quality implementation that is not suitable for production use and will change in backward-incompatible ways in future releases. Please see [the documentation](https://github.com/ClickHouse/ClickHouse/blob/master/docs/en/sql-reference/window-functions/index.md#experimental-window-functions) for the list of supported features. [#20337](https://github.com/ClickHouse/ClickHouse/pull/20337) ([Alexander Kuzmenkov](https://github.com/akuzm)).

 Nevertheless, it is possible to work with individual values as well. To represent an individual value, the `Field` is used. `Field` is just a discriminated union of `UInt64`, `Int64`, `Float64`, `String` and `Array`. `IColumn` has the `operator []` method to get the n-th value as a `Field`, and the `insert` method to append a `Field` to the end of a column. These methods are not very efficient, because they require dealing with temporary `Field` objects representing an individual value. There are more efficient methods, such as `insertFrom`, `insertRangeFrom`, and so on.

 A `Block` is a container that represents a subset (chunk) of a table in memory. It is just a set of triples: `(IColumn, IDataType, column name)`. During query execution, data is processed by `Block`s. If we have a `Block`, we have data (in the `IColumn` object), we have information about its type (in `IDataType`) that tells us how to deal with that column, and we have the column name. It could be either the original column name from the table or some artificial name assigned for getting temporary results of calculations.

 Blocks are created for every processed chunk of data. Note that for the same type of calculation, the column names and types remain the same for different blocks, and only column data changes.

 `MergeTree` is a family of storage engines that supports indexing by primary key. The primary key can be an arbitrary tuple of columns or expressions. Data in a `MergeTree` table is stored in “parts”. Each part stores data in the primary key order, so data is ordered lexicographically by the primary key tuple. All the table columns are stored in separate `column.bin` files in these parts. The files consist of compressed blocks. Each block is usually from 64 KB to 1 MB of uncompressed data, depending on the average value size. The blocks consist of column values placed contiguously one after the other. Column values are in the same order for each column (the primary key defines the order), so when you iterate by many columns, you get values for the corresponding rows.
 
-The primary key itself is “sparse”. It doesn’t address every single row, but only some ranges of data. A separate `primary.idx` file has the value of the primary key for each N-th row, where N is called `index_granularity` (usually, N = 8192). Also, for each column, we have `column.mrk` files with “marks,” which are offsets to each N-th row in the data file. Each mark is a pair: the offset in the file to the beginning of the compressed block, and the offset in the decompressed block to the beginning of data. Usually, compressed blocks are aligned by marks, and the offset in the decompressed block is zero. Data for `primary.idx` always resides in memory, and data for `column.mrk` files is cached.

Usually, compressed blocks are aligned by marks, and the offset in the decompressed block is zero. Data for `primary.idx` always resides in memory, and data for `column.mrk` files is cached.
 
 When we are going to read something from a part in `MergeTree`, we look at `primary.idx` data and locate ranges that could contain requested data, then look at `column.mrk` data and calculate offsets for where to start reading those ranges. Because of sparseness, excess data may be read. ClickHouse is not suitable for a high load of simple point queries, because the entire range with `index_granularity` rows must be read for each key, and the entire compressed block must be decompressed for each column. We made the index sparse because we must be able to maintain trillions of rows per single server without noticeable memory consumption for the index. Also, because the primary key is sparse, it is not unique: it cannot check the existence of the key in the table at INSERT time. You could have many rows with the same key in a table.
 
 When you `INSERT` a bunch of data into `MergeTree`, that bunch is sorted by primary key order and forms a new part. There are background threads that periodically select some parts and merge them into a single sorted part to keep the number of parts relatively low. That’s why it is called `MergeTree`. Of course, merging leads to “write amplification”. All parts are immutable: they are only created and deleted, but not modified. When SELECT is executed, it holds a snapshot of the table (a set of parts). After merging, we also keep old parts for some time to make a recovery after failure easier, so if we see that some merged part is probably broken, we can replace it with its source parts.
 
-`MergeTree` is not an LSM tree because it doesn’t contain “memtable” and “log”: inserted data is written directly to the filesystem. This makes it suitable only to INSERT data in batches, not by individual row and not very frequently – about once per second is ok, but a thousand times a second is not. We did it this way for simplicity’s sake, and because we are already inserting data in batches in our applications.

 There are MergeTree engines that are doing additional work during background merges. Examples are `CollapsingMergeTree` and `AggregatingMergeTree`. This could be treated as special support for updates. Keep in mind that these are not real updates because users usually have no control over the time when background merges are executed, and data in a `MergeTree` table is almost always stored in more than one part, not in completely merged form.

 Replication is implemented in the `ReplicatedMergeTree` storage engine. The path in `ZooKeeper` is specified as a parameter for the storage engine. All tables with the same path in `ZooKeeper` become replicas of each other: they synchronize their data and maintain consistency. Replicas can be added and removed dynamically simply by creating or dropping a table.
 
-Replication uses an asynchronous multi-master scheme. You can insert data into any replica that has a session with `ZooKeeper`, and data is replicated to all other replicas asynchronously. Because ClickHouse doesn’t support UPDATEs, replication is conflict-free. As there is no quorum acknowledgment of inserts, just-inserted data might be lost if one node fails.

Because ClickHouse does not support UPDATEs, replication is conflict-free. As there is no quorum acknowledgment of inserts, just-inserted data might be lost if one node fails.
 
 Metadata for replication is stored in ZooKeeper. There is a replication log that lists what actions to do. Actions are: get part; merge parts; drop a partition, and so on. Each replica copies the replication log to its queue and then executes the actions from the queue. For example, on insertion, the “get the part” action is created in the log, and every replica downloads that part. Merges are coordinated between replicas to get byte-identical results. All parts are merged in the same way on all replicas. One of the leaders initiates a new merge first and writes “merge parts” actions to the log. Multiple replicas (or all) can be leaders at the same time. A replica can be prevented from becoming a leader using the `merge_tree` setting `replicated_can_become_leader`. The leaders are responsible for scheduling background merges.

This executable must be re-linked on every change, which might be slow. Two common ways to improve linking time are to use `lld` linker, and use the 'split' build configuration, which builds a separate binary for every tool, and further splits the code into serveral shared libraries.

-# CMake in ClickHouse
-
-## TL; DR How to make ClickHouse compile and link faster?
-
-Developer only! This command will likely fulfill most of your needs. Run before calling `ninja`.
-
-```cmake
-cmake .. \
-    -DCMAKE_C_COMPILER=/bin/clang-10 \
-    -DCMAKE_CXX_COMPILER=/bin/clang++-10 \
-    -DCMAKE_BUILD_TYPE=Debug \

-    -DUSE_UNWIND=ON \
-    -DENABLE_UTILS=OFF \
-    -DENABLE_TESTS=OFF
-```
-
-## CMake files types
-
-1. ClickHouse's source CMake files (located in the root directory and in `/src`).
-2. Arch-dependent CMake files (located in `/cmake/*os_name*`).
-3. Libraries finders (search for contrib libraries, located in `/cmake/find`).
-3. Contrib build CMake files (used instead of libraries' own CMake files, located in `/cmake/modules`)
-
-## List of CMake flags
-
-* This list is auto-generated by [this Python script](https://github.com/clickhouse/clickhouse/blob/master/docs/tools/cmake_in_clickhouse_generator.py).
-* The flag name is a link to its position in the code.
-* If an option's default value is itself an option, it's also a link to its position in this list.

-## Developer's guide for adding new CMake options
-
-### Don't be obvious. Be informative.
-
-Bad:
-```cmake
-option (ENABLE_TESTS "Enables testing" OFF)
-```
-
-This description is quite useless as is neither gives the viewer any additional information nor explains the option purpose.
-
-Better:
-
-```cmake
-option(ENABLE_TESTS "Provide unit_test_dbms target with Google.test unit tests" OFF)
-```
-
-If the option's purpose can't be guessed by its name, or the purpose guess may be misleading, or option has some 
-pre-conditions, leave a comment above the `option()` line and explain what it does. 
-The best way would be linking the docs page (if it exists).
-The comment is parsed into a separate column (see below).
-
-Even better:
-
-```cmake
-# implies ${TESTS_ARE_ENABLED}
-# see tests/CMakeLists.txt for implementation detail.
-option(ENABLE_TESTS "Provide unit_test_dbms target with Google.test unit tests" OFF)
-```
-
-### If the option's state could produce unwanted (or unusual) result, explicitly warn the user.
-
-Suppose you have an option that may strip debug symbols from the ClickHouse's part.
-This can speed up the linking process, but produces a binary that cannot be debugged.
-In that case, prefer explicitly raising a warning telling the developer that he may be doing something wrong. 
-Also, such options should be disabled if applies.
-
-Bad:
-```cmake
-option(STRIP_DEBUG_SYMBOLS_FUNCTIONS
-    "Do not generate debugger info for ClickHouse functions.
-    ${STRIP_DSF_DEFAULT})
-
-if (STRIP_DEBUG_SYMBOLS_FUNCTIONS)
-    target_compile_options(clickhouse_functions PRIVATE "-g0")
-endif()
-
-```
-Better:
-
-```cmake
-# Provides faster linking and lower binary size.
-# Tradeoff is the inability to debug some source files with e.g. gdb
-# (empty stack frames and no local variables)."
-option(STRIP_DEBUG_SYMBOLS_FUNCTIONS
-    "Do not generate debugger info for ClickHouse functions."
-    ${STRIP_DSF_DEFAULT})
-
-if (STRIP_DEBUG_SYMBOLS_FUNCTIONS)
-    message(WARNING "Not generating debugger info for ClickHouse functions")
-    target_compile_options(clickhouse_functions PRIVATE "-g0")
-endif()
-```
-
-### In the option's description, explain WHAT the option does rather than WHY it does something.
-
-The WHY explanation should be placed in the comment.
-You may find that the option's name is self-descriptive.
-
-Bad:
-
-```cmake
-option(ENABLE_THINLTO "Enable Thin LTO. Only applicable for clang. It's also suppressed when building with tests or sanitizers." ON)
-```
-
-Better:
-
-```cmake
-# Only applicable for clang.
-# Turned off when building with tests or sanitizers.
-option(ENABLE_THINLTO "Clang-specific link time optimisation" ON).
-```
-
-### Don't assume other developers know as much as you do.
-
-In ClickHouse, there are many tools used that an ordinary developer may not know. If you are in doubt, give a link to
-the tool's docs. It won't take much of your time.
-
-Bad:
-
-```cmake
-option(ENABLE_THINLTO "Enable Thin LTO. Only applicable for clang. It's also suppressed when building with tests or sanitizers." ON)
-```
-
-Better (combined with the above hint):
-
-```cmake
-# https://clang.llvm.org/docs/ThinLTO.html
-# Only applicable for clang.
-# Turned off when building with tests or sanitizers.
-option(ENABLE_THINLTO "Clang-specific link time optimisation" ON).
-```
-
-Other example, bad:
-
-```cmake
-option (USE_INCLUDE_WHAT_YOU_USE "Use 'include-what-you-use' tool" OFF)
-```
-
-Better:
-
-```cmake
-# https://github.com/include-what-you-use/include-what-you-use
-option (USE_INCLUDE_WHAT_YOU_USE "Reduce unneeded #include s (external tool)" OFF)
-```
-
-### Prefer consistent default values.
-
-CMake allows you to pass a plethora of values representing boolean `true/false`, e.g. `1, ON, YES, ...`.
-Prefer the `ON/OFF` values, if possible.

+It supports non-blocking [DROP TABLE](#drop-detach-table) and [RENAME TABLE](#rename-table) queries and atomic [EXCHANGE TABLES t1 AND t2](#exchange-tables) queries. `Atomic` database engine is used by default.

+## Specifics and recommendations {#specifics-and-recommendations}
+
+### Table UUID {#table-uuid}
+
+All tables in database `Atomic` have persistent [UUID](../../sql-reference/data-types/uuid.md) and store data in directory `/clickhouse_path/store/xxx/xxxyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy/`, where `xxxyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy` is UUID of the table. 
+Usually, the UUID is generated automatically, but the user can also explicitly specify the UUID in the same way when creating the table (this is not recommended). To display the `SHOW CREATE` query with the UUID you can use setting [show_table_uuid_in_table_create_query_if_not_nil](../../operations/settings/settings.md#show_table_uuid_in_table_create_query_if_not_nil). For example:
+
+```sql
+CREATE TABLE name UUID '28f1c61c-2970-457a-bffe-454156ddcfef' (n UInt64) ENGINE = ...;
+```
+### RENAME TABLE {#rename-table}
+
+`RENAME` queries are performed without changing UUID and moving table data. These queries do not wait for the completion of queries using the table and will be executed instantly.
+
+### DROP/DETACH TABLE {#drop-detach-table}
+
+On `DROP TABLE` no data is removed, database `Atomic` just marks table as dropped by moving metadata to `/clickhouse_path/metadata_dropped/` and notifies background thread. Delay before final table data deletion is specify by [database_atomic_delay_before_drop_table_sec](../../operations/server-configuration-parameters/settings.md#database_atomic_delay_before_drop_table_sec) setting.
+You can specify synchronous mode using `SYNC` modifier. Use the [database_atomic_wait_for_drop_and_detach_synchronously](../../operations/settings/settings.md#database_atomic_wait_for_drop_and_detach_synchronously) setting to do this. In this case `DROP` waits for running `SELECT`, `INSERT` and other queries which are using the table to finish. Table will be actually removed when it's not in use.
+
+### EXCHANGE TABLES {#exchange-tables}
+
+`EXCHANGE` query swaps tables atomically. So instead of this non-atomic operation:
+
+```sql
+RENAME TABLE new_table TO tmp, old_table TO new_table, tmp TO old_table;
+```
+you can use one atomic query:
+
+``` sql
+EXCHANGE TABLES new_table AND old_table;
+```
+
+### ReplicatedMergeTree in Atomic Database {#replicatedmergetree-in-atomic-database}
+
+For [ReplicatedMergeTree](../table-engines/mergetree-family/replication.md#table_engines-replication) tables, it is recommended to not specify engine parameters - path in ZooKeeper and replica name. In this case, configuration parameters will be used [default_replica_path](../../operations/server-configuration-parameters/settings.md#default_replica_path) and [default_replica_name](../../operations/server-configuration-parameters/settings.md#default_replica_name). If you want to specify engine parameters explicitly, it is recommended to use {uuid} macros. This is useful so that unique paths are automatically generated for each table in ZooKeeper.

+
+Allows to connect to databases on a remote [PostgreSQL](https://www.postgresql.org) server. Supports read and write operations (`SELECT` and `INSERT` queries) to exchange data between ClickHouse and PostgreSQL.

+## Examples of Use {#examples-of-use}
+
+Database in ClickHouse, exchanging data with the PostgreSQL server:
+
+``` sql
+CREATE DATABASE test_database 
+ENGINE = PostgreSQL('postgres1:5432', 'test_database', 'postgres', 'mysecretpassword', 1);
+```
+
+``` sql
+SHOW DATABASES;
+```
+
+``` text
+┌─name──────────┐
+│ default       │
+│ test_database │
+│ system        │
+└───────────────┘
+```
+
+``` sql
+SHOW TABLES FROM test_database;
+```
+
+``` text
+┌─name───────┐
+│ test_table │
+└────────────┘
+```
+
+Reading data from the PostgreSQL table:
+
+``` sql
+SELECT * FROM test_database.test_table;
+```
+
+``` text
+┌─id─┬─value─┐
+│  1 │     2 │
+└────┴───────┘
+```
+
+Writing data to the PostgreSQL table:
+
+``` sql
+INSERT INTO test_database.test_table VALUES (3,4);
+SELECT * FROM test_database.test_table;
+```
+
+``` text
+┌─int_id─┬─value─┐
+│      1 │     2 │
+│      3 │     4 │
+└────────┴───────┘
+```
+
+Consider the table structure was modified in PostgreSQL: 
+
+``` sql
+postgre> ALTER TABLE test_table ADD COLUMN data Text
+```
+
+As the `use_table_cache` parameter was set to `1` when the database was created, the table structure in ClickHouse was cached and therefore not modified:
+
+``` sql
+DESCRIBE TABLE test_database.test_table;
+```
+``` text
+┌─name───┬─type──────────────┐
+│ id     │ Nullable(Integer) │
+│ value  │ Nullable(Integer) │
+└────────┴───────────────────┘
+```
+
+After detaching the table and attaching it again, the structure was updated:
+
+``` sql
+DETACH TABLE test_database.test_table;
+ATTACH TABLE test_database.test_table;
+DESCRIBE TABLE test_database.test_table;
+```
+``` text
+┌─name───┬─type──────────────┐
+│ id     │ Nullable(Integer) │
+│ value  │ Nullable(Integer) │
+│ data   │ Nullable(String)  │
+└────────┴───────────────────┘

+-   ‘https://storage.yandexcloud.net/my-test-bucket-768/some_prefix/some_file_2.csv’

+-   ‘https://storage.yandexcloud.net/my-test-bucket-768/another_prefix/some_file_3.csv’
+
+There are several ways to make a table consisting of all six files:
+
+The first way:
+
+``` sql
+CREATE TABLE table_with_range (name String, value UInt32) ENGINE = S3('https://storage.yandexcloud.net/my-test-bucket-768/{some,another}_prefix/some_file_{1..3}', 'CSV');

+``` sql
+CREATE TABLE table_with_question_mark (name String, value UInt32) ENGINE = S3('https://storage.yandexcloud.net/my-test-bucket-768/{some,another}_prefix/some_file_?', 'CSV');
+```
+
+Table consists of all the files in both directories (all files should satisfy format and schema described in query):
+
+``` sql
+CREATE TABLE table_with_asterisk (name String, value UInt32) ENGINE = S3('https://storage.yandexcloud.net/my-test-bucket-768/{some,another}_prefix/*', 'CSV');
+```
+
+If the listing of files contains number ranges with leading zeros, use the construction with braces for each digit separately or use `?`.
+
+**Example**
+
+Create table with files named `file-000.csv`, `file-001.csv`, … , `file-999.csv`:
+
+``` sql
+CREATE TABLE big_table (name String, value UInt32) ENGINE = S3('https://storage.yandexcloud.net/my-test-bucket-768/big_prefix/file-{000..999}.csv', 'CSV');

 The `Log` and `StripeLog` engines support parallel data reading. When reading data, ClickHouse uses multiple threads. Each thread processes a separate data block. The `Log` engine uses a separate file for each column of the table. `StripeLog` stores all the data in one file. As a result, the `StripeLog` engine uses fewer file descriptors, but the `Log` engine provides higher efficiency when reading data.

 ZooKeeper is not used in `SELECT` queries because replication does not affect the performance of `SELECT` and queries run just as fast as they do for non-replicated tables. When querying distributed replicated tables, ClickHouse behavior is controlled by the settings [max_replica_delay_for_distributed_queries](../../../operations/settings/settings.md#settings-max_replica_delay_for_distributed_queries) and [fallback_to_stale_replicas_for_distributed_queries](../../../operations/settings/settings.md#settings-fallback_to_stale_replicas_for_distributed_queries).

(To be more precise, this is for each inserted block of data; an INSERT query contains one block or one block per `max_insert_block_size = 1048576` rows.) This leads to slightly longer latencies for `INSERT` compared to non-replicated tables. But if you follow the recommendations to insert data in batches of no more than one `INSERT` per second, it doesn’t create any problems. The entire ClickHouse cluster used for coordinating one ZooKeeper cluster has a total of several hundred `INSERTs` per second. The throughput on data inserts (the number of rows per second) is just as high as for non-replicated data.

The entire ClickHouse cluster used for coordinating one ZooKeeper cluster has a total of several hundred `INSERTs` per second. The throughput on data inserts (the number of rows per second) is just as high as for non-replicated data.
 
 For very large clusters, you can use different ZooKeeper clusters for different shards. However, this hasn’t proven necessary on the Yandex.Metrica cluster (approximately 300 servers).
 
 Replication is asynchronous and multi-master. `INSERT` queries (as well as `ALTER`) can be sent to any available server. Data is inserted on the server where the query is run, and then it is copied to the other servers. Because it is asynchronous, recently inserted data appears on the other replicas with some latency. If part of the replicas are not available, the data is written when they become available. If a replica is available, the latency is the amount of time it takes to transfer the block of compressed data over the network. The number of threads performing background tasks for replicated tables can be set by [background_schedule_pool_size](../../../operations/settings/settings.md#background_schedule_pool_size) setting.
 
+`ReplicatedMergeTree` engine uses a separate thread pool for replicated fetches. Size of the pool is limited by the [background_fetches_pool_size](../../../operations/settings/settings.md#background_fetches_pool_size) setting which can be tuned with a server restart. 
+
 By default, an INSERT query waits for confirmation of writing the data from only one replica. If the data was successfully written to only one replica and the server with this replica ceases to exist, the stored data will be lost. To enable getting confirmation of data writes from multiple replicas, use the `insert_quorum` option.
 
 Each block of data is written atomically. The INSERT query is divided into blocks up to `max_insert_block_size = 1048576` rows. In other words, if the `INSERT` query has less than 1048576 rows, it is made atomically.
 
-Data blocks are deduplicated. For multiple writes of the same data block (data blocks of the same size containing the same rows in the same order), the block is only written once. The reason for this is in case of network failures when the client application doesn’t know if the data was written to the DB, so the `INSERT` query can simply be repeated. It doesn’t matter which replica INSERTs were sent to with identical data. `INSERTs` are idempotent. Deduplication parameters are controlled by [merge_tree](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-merge_tree) server settings.

Deduplication parameters are controlled by [merge_tree](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-merge_tree) server settings.
 
 During replication, only the source data to insert is transferred over the network. Further data transformation (merging) is coordinated and performed on all the replicas in the same way. This minimizes network usage, which means that replication works well when replicas reside in different datacenters. (Note that duplicating data in different datacenters is the main goal of replication.)

 The engine inherits from [MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md#table_engines-mergetree). The difference is that when merging data parts for `SummingMergeTree` tables ClickHouse replaces all the rows with the same primary key (or more accurately, with the same [sorting key](../../../engines/table-engines/mergetree-family/mergetree.md)) with one row which contains summarized values for the columns with the numeric data type. If the sorting key is composed in a way that a single key value corresponds to large number of rows, this significantly reduces storage volume and speeds up data selection.
 
-We recommend to use the engine together with `MergeTree`. Store complete data in `MergeTree` table, and use `SummingMergeTree` for aggregated data storing, for example, when preparing reports. Such an approach will prevent you from losing valuable data due to an incorrectly composed primary key.

 There are two methods for writing data to a cluster:
 
 First, you can define which servers to write which data to and perform the write directly on each shard. In other words, perform INSERT in the tables that the distributed table “looks at”. This is the most flexible solution as you can use any sharding scheme, which could be non-trivial due to the requirements of the subject area. This is also the most optimal solution since data can be written to different shards completely independently.
 
-Second, you can perform INSERT in a Distributed table. In this case, the table will distribute the inserted data across the servers itself. In order to write to a Distributed table, it must have a sharding key set (the last parameter).

+ClickHouse does not have real-time point deletes like in [OLTP](https://en.wikipedia.org/wiki/Online_transaction_processing) databases. The closest thing to them are mutations. They are issued as `ALTER ... DELETE` or `ALTER ... UPDATE` queries to distinguish from normal `DELETE` or `UPDATE` as they are asynchronous batch operations, not immediate modifications. The rest of syntax after `ALTER TABLE` prefix is similar.
 
 `ALTER DELETE` can be issued to flexibly remove old data. If you need to do it regularly, the main downside will be the need to have an external system to submit the query. There are also some performance considerations since mutation rewrite complete parts even there’s only a single row to be deleted.

+## YAML examples {#example}
+
+Here you can see default config written in YAML: [config.yaml.example](https://github.com/ClickHouse/ClickHouse/blob/master/programs/server/config.yaml.example).
+
+There are some differences between YAML and XML formats in terms of ClickHouse configurations. Here are some tips for writing a configuration in YAML format.
+
+You should use a Scalar node to write a key-value pair:
+``` yaml
+key: value
+```
+
+To create a node, containing other nodes you should use a Map:
+``` yaml
+map_key:
+  key1: val1
+  key2: val2
+  key3: val3
+```
+
+To create a list of values or nodes assigned to one tag you should use a Sequence:
+``` yaml
+seq_key:
+  - val1
+  - val2
+  - key1: val3
+  - map:
+      key2: val4
+      key3: val5
+```
+
+If you want to write an attribute for a Sequence or Map node, you should use a @ prefix before the attribute key. Note, that @ is reserved by YAML standard, so you should also to wrap it into double quotes:
+
+``` yaml
+map:
+  "@attr1": value1
+  "@attr2": value2
+  key: 123
+```
+
+From that Map we will get these XML nodes:
+
+``` xml
+<map attr1="value1" attr2="value2">
+    <key>123</key>
+</map>
+```
+
+You can also set attributes for Sequence:
+
+``` yaml
+seq:
+  - "@attr1": value1
+  - "@attr2": value2
+  - 123
+  - abc
+```
+
+So, we can get YAML config equal to this XML one:
+
+``` xml
+<seq attr1="value1" attr2="value2">123</seq>
+<seq attr1="value1" attr2="value2">abc</seq>
+```
+
 ## Implementation Details {#implementation-details}
 
 For each config file, the server also generates `file-preprocessed.xml` files when starting. These files contain all the completed substitutions and overrides, and they are intended for informational use. If ZooKeeper substitutions were used in the config files but ZooKeeper is not available on the server start, the server loads the configuration from the preprocessed file.

 For instance, example01-01-1 and example01-01-2.yandex.ru are different in one position, while example01-01-1 and example01-02-2 differ in two places.

 Thus, if there are equivalent replicas, the closest one by name is preferred.
 We can also assume that when sending a query to the same server, in the absence of failures, a distributed query will also go to the same servers. So even if different data is placed on the replicas, the query will return mostly the same results.

+
+Allows formatting input queries.
+
+Keys:
+
+- `--help` or`-h` — Produce help message.
+- `--hilite` — Add syntax highlight with ANSI terminal escape sequences.
+- `--oneline` — Format in single line.
+- `--quiet` or `-q` — Just check syntax, no output on success.
+- `--multiquery` or `-n` — Allow multiple queries in the same file.
+- `--obfuscate` — Obfuscate instead of formatting.
+- `--seed <string>` — Seed arbitrary string that determines the result of obfuscation.
+- `--backslash` — Add a backslash at the end of each line of the formatted query. Can be useful when you copy a query from web or somewhere else with multiple lines, and want to execute it in command line.
+
+## Examples {#examples} 
+
+1. Highlighting and single line:
+
+```bash
+$ clickhouse-format --oneline --hilite <<< "SELECT sum(number) FROM numbers(5);"
+```
+
+Result:
+
+```sql
+SELECT sum(number) FROM numbers(5)
+```
+
+2. Multiqueries: 
+
+```bash
+$ clickhouse-format -n <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
+```
+    
+Result:
+
+```text
+SELECT *
+FROM
+(
+    SELECT 1 AS x
+    UNION ALL
+    SELECT 1
+    UNION DISTINCT
+    SELECT 3
+)
+;
+```
+
+3. Obfuscating:
+
+```bash
+$ clickhouse-format --seed Hello --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
+```
+    
+Result:
+
+```text
+SELECT treasury_mammoth_hazelnut BETWEEN nutmeg AND span, CASE WHEN chive >= 116 THEN switching ELSE ANYTHING END;
+```
+   
+Same query and another seed string:
+
+```bash
+$ clickhouse-format --seed World --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
+```
+
+Result:
+
+```text
+SELECT horse_tape_summer BETWEEN folklore AND moccasins, CASE WHEN intestine >= 116 THEN nonconformist ELSE FORESTRY END;
+```
+
+4. Adding backslash:
+
+```bash
+$ clickhouse-format --backslash <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
+```
+
+Result:
+
+```text
+SELECT * \
+FROM  \

+    SELECT 1 AS x \

-# ClickHouse obfuscator
-
-A simple tool for table data obfuscation.
-
-It reads an input table and produces an output table, that retains some properties of input, but contains different data.
-It allows publishing almost real production data for usage in benchmarks.
-
-It is designed to retain the following properties of data:
-- cardinalities of values (number of distinct values) for every column and every tuple of columns;
-- conditional cardinalities: number of distinct values of one column under the condition on the value of another column;
-- probability distributions of the absolute value of integers; the sign of signed integers; exponent and sign for floats;
-- probability distributions of the length of strings;

+# ClickHouse obfuscator
+
+A simple tool for table data obfuscation.
+
+It reads an input table and produces an output table, that retains some properties of input, but contains different data.
+It allows publishing almost real production data for usage in benchmarks.
+
+It is designed to retain the following properties of data:
+- cardinalities of values (number of distinct values) for every column and every tuple of columns;
+- conditional cardinalities: number of distinct values of one column under the condition on the value of another column;
+- probability distributions of the absolute value of integers; the sign of signed integers; exponent and sign for floats;
+- probability distributions of the length of strings;
+- probability of zero values of numbers; empty strings and arrays, `NULL`s;
+
+- data compression ratio when compressed with LZ77 and entropy family of codecs;
+- continuity (magnitude of difference) of time values across the table; continuity of floating-point values;
+- date component of `DateTime` values;
+
+- UTF-8 validity of string values;

+ClickHouse does not have the concept of encodings. Strings can contain an arbitrary set of bytes, which are stored and output as-is.
 If you need to store texts, we recommend using UTF-8 encoding. At the very least, if your terminal uses UTF-8 (as recommended), you can read and write your values without making conversions.
 Similarly, certain functions for working with strings have separate variations that work under the assumption that the string contains a set of bytes representing a UTF-8 encoded text.
 For example, the ‘length’ function calculates the string length in bytes, while the ‘lengthUTF8’ function calculates the string length in Unicode code points, assuming that the value is UTF-8 encoded.

-Accepts a string containing any number of hexadecimal digits, and returns a string containing the corresponding bytes. Supports both uppercase and lowercase letters A-F. The number of hexadecimal digits does not have to be even. If it is odd, the last digit is interpreted as the least significant half of the 00-0F byte. If the argument string contains anything other than hexadecimal digits, some implementation-defined result is returned (an exception isn’t thrown).
-If you want to convert the result to a number, you can use the ‘reverse’ and ‘reinterpretAsType’ functions.
+Performs the opposite operation of [hex](#hex). It interprets each pair of hexadecimal digits (in the argument) as a number and converts it to the byte represented by the number. The return value is a binary string (BLOB).
+
+If you want to convert the result to a number, you can use the [reverse](../../sql-reference/functions/string-functions.md#reverse) and [reinterpretAs<Type>](../../sql-reference/functions/type-conversion-functions.md#type-conversion-functions) functions.

+## extractTextFromHTML {#extracttextfromhtml}
+
+A function to extract text from HTML or XHTML.
+It does not necessarily 100% conform to any of the HTML, XML or XHTML standards, but the implementation is reasonably accurate and it is fast. The rules are the following:
+
+1. Comments are skipped. Example: `<!-- test -->`. Comment must end with `-->`. Nested comments are not possible.
+Note: constructions like `<!-->` and `<!--->` are not valid comments in HTML but they are skipped by other rules.
+2. CDATA is pasted verbatim. Note: CDATA is XML/XHTML specific. But it is processed for "best-effort" approach.
+3. `script` and `style` elements are removed with all their content. Note: it is assumed that closing tag cannot appear inside content. For example, in JS string literal has to be escaped like `"<\/script>"`.
+Note: comments and CDATA are possible inside `script` or `style` - then closing tags are not searched inside CDATA. Example: `<script><![CDATA[</script>]]></script>`. But they are still searched inside comments. Sometimes it becomes complicated: `<script>var x = "<!--"; </script> var y = "-->"; alert(x + y);</script>`
+Note: `script` and `style` can be the names of XML namespaces - then they are not treated like usual `script` or `style` elements. Example: `<script:a>Hello</script:a>`.
+Note: whitespaces are possible after closing tag name: `</script >` but not before: `< / script>`.
+4. Other tags or tag-like elements are skipped without inner content. Example: `<a>.</a>`
+Note: it is expected that this HTML is illegal: `<a test=">"></a>`
+Note: it also skips something like tags: `<>`, `<!>`, etc.
+Note: tag without end is skipped to the end of input: `<hello   `
+5. HTML and XML entities are not decoded. They must be processed by separate function.
+6. Whitespaces in the text are collapsed or inserted by specific rules.
+    - Whitespaces at the beginning and at the end are removed.
+    - Consecutive whitespaces are collapsed.
+    - But if the text is separated by other elements and there is no whitespace, it is inserted.
+    - It may cause unnatural examples: `Hello<b>world</b>`, `Hello<!-- -->world` - there is no whitespace in HTML, but the function inserts it. Also consider: `Hello<p>world</p>`, `Hello<br>world`. This behavior is reasonable for data analysis, e.g. to convert HTML to a bag of words.
+7. Also note that correct handling of whitespaces requires the support of `<pre></pre>` and CSS `display` and `white-space` properties.

+Keyword `ALL` means all the ClickHouse users including current user. Keyword `ALL EXCEPT` allow to exclude some users from the all users list, for example, `CREATE ROW POLICY ... TO ALL EXCEPT accountant, john@localhost`
 
-## Examples {#examples}
+!!! note "Note"
+    If there are no row policies defined for a table then any user can `SELECT` all the row from the table. Defining one or more row policies for the table makes the access to the table depending on the row policies no matter if those row policies are defined for the current user or not. For example, the following policy
+    
+    `CREATE ROW POLICY pol1 ON mydb.table1 USING b=1 TO mira, peter`
 
-`CREATE ROW POLICY filter ON mydb.mytable FOR SELECT USING a<1000 TO accountant, john@localhost`
+    forbids the users `mira` and `peter` to see the rows with `b != 1`, and any non-mentioned user (e.g., the user `paul`) will see no rows from `mydb.table1` at all.
+    
+    If that's not desirable it can't be fixed by adding one more row policy, like the following:
 
-`CREATE ROW POLICY filter ON mydb.mytable FOR SELECT USING a<1000 TO ALL EXCEPT mira`
+    `CREATE ROW POLICY pol2 ON mydb.table1 USING 1 TO ALL EXCEPT mira, peter`
+
+## AS Clause {#create-row-policy-as}
+
+It's allowed to have more than one policy enabled on the same table for the same user at the one time. So we need a way to combine the conditions from multiple policies.
+
+By default policies are combined using the boolean `OR` operator. For example, the following policies
+
+``` sql
+CREATE ROW POLICY pol1 ON mydb.table1 USING b=1 TO mira, peter
+CREATE ROW POLICY pol2 ON mydb.table1 USING c=2 TO peter, antonio
+```
+
+enables the user `peter` to see rows with either `b=1` or `c=2`.
+
+The `AS` clause specifies how policies should be combined with other policies. Policies can be either permissive or restrictive. By default policies are permissive, which means they are combined using the boolean `OR` operator.
+
+A policy can be defined as restrictive as an alternative. Restrictive policies are combined using the boolean `AND` operator.
+
+Here is the general formula:
+
+```
+row_is_visible = (one or more of the permissive policies' conditions are non-zero) AND
+                 (all of the restrictive policies's conditions are non-zero)
+```
+
+For example, the following policies
+
+``` sql
+CREATE ROW POLICY pol1 ON mydb.table1 USING b=1 TO mira, peter
+CREATE ROW POLICY pol2 ON mydb.table1 USING c=2 AS RESTRICTIVE TO peter, antonio
+```
+
+enables the user `peter` to see rows only if both `b=1` AND `c=2`.

Up to `delta_bytes` are used for storing delta values, so `delta_bytes` is the maximum size of raw values. Possible `delta_bytes` values: 1, 2, 4, 8. The default value for `delta_bytes` is `sizeof(type)` if equal to 1, 2, 4, or 8. In all other cases, it’s 1.
 -   `DoubleDelta` — Calculates delta of deltas and writes it in compact binary form. Optimal compression rates are achieved for monotonic sequences with a constant stride, such as time series data. Can be used with any fixed-width type. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. Uses 1 extra bit for 32-byte deltas: 5-bit prefixes instead of 4-bit prefixes. For additional information, see Compressing Time Stamps in [Gorilla: A Fast, Scalable, In-Memory Time Series Database](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
 -   `Gorilla` — Calculates XOR between current and previous value and writes it in compact binary form. Efficient when storing a series of floating point values that change slowly, because the best compression rate is achieved when neighboring values are binary equal. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. For additional information, see Compressing Values in [Gorilla: A Fast, Scalable, In-Memory Time Series Database](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
--   `T64` — Compression approach that crops unused high bits of values in integer data types (including `Enum`, `Date` and `DateTime`). At each step of its algorithm, codec takes a block of 64 values, puts them into 64x64 bit matrix, transposes it, crops the unused bits of values and returns the rest as a sequence. Unused bits are the bits, that don’t differ between maximum and minimum values in the whole data part for which the compression is used.

 `DoubleDelta` and `Gorilla` codecs are used in Gorilla TSDB as the components of its compressing algorithm. Gorilla approach is effective in scenarios when there is a sequence of slowly changing values with their timestamps. Timestamps are effectively compressed by the `DoubleDelta` codec, and values are effectively compressed by the `Gorilla` codec.

For example, if `GROUP BY` is set, data is aggregated during insertion, but only within a single packet of inserted data. The data won’t be further aggregated. The exception is when using an `ENGINE` that independently performs data aggregation, such as `SummingMergeTree`.

 When you set `WITH TIES` modifier for `LIMIT n[,m]` and specify `ORDER BY expr_list`, you will get in result first `n` or `n,m` rows and all rows with same `ORDER BY` fields values equal to row at position `n` for `LIMIT n` and `m` for `LIMIT n,m`.

+`OFFSET` and `FETCH` allow you to retrieve data by portions. They specify a row block which you want to get by a single query.
+
+``` sql
+OFFSET offset_row_count {ROW | ROWS}] [FETCH {FIRST | NEXT} fetch_row_count {ROW | ROWS} {ONLY | WITH TIES}]
+```
+
+The `offset_row_count` or `fetch_row_count` value can be a number or a literal constant. You can omit `fetch_row_count`; by default, it equals to 1.
+
+`OFFSET` specifies the number of rows to skip before starting to return rows from the query result set.
+
+The `FETCH` specifies the maximum number of rows that can be in the result of a query.
+
+The `ONLY` option is used to return rows that immediately follow the rows omitted by the `OFFSET`. In this case the `FETCH` is an alternative to the [LIMIT](../../../sql-reference/statements/select/limit.md) clause. For example, the following query
+
+``` sql
+SELECT * FROM test_fetch ORDER BY a OFFSET 1 ROW FETCH FIRST 3 ROWS ONLY;
+```
+
+is identical to the query
+
+``` sql
+SELECT * FROM test_fetch ORDER BY a LIMIT 3 OFFSET 1;
+```
+
+The `WITH TIES` option is used to return any additional rows that tie for the last place in the result set according to the `ORDER BY` clause. For example, if `fetch_row_count` is set to 5 but two additional rows match the values of the `ORDER BY` columns in the fifth row, the result set will contain seven rows.
+
+!!! note "Note"

 **Usage**
 
-Using the `remote` table function is less optimal than creating a `Distributed` table because in this case the server connection is re-established for every request. Also, if hostnames are set, the names are resolved, and errors are not counted when working with various replicas. When processing a large number of queries, always create the `Distributed` table ahead of time, and don’t use the `remote` table function.

This might result in large merges running after the server upgrade, which could cause an increased load on the disk subsystem. If the free space available on the server is less than twice the total amount of the merges that are running, this will cause all other merges to stop running, including merges of small data parts. As a result, INSERT queries will fail with the message “Merges are processing significantly slower than inserts.” Use the `SELECT * FROM system.merges` query to monitor the situation. You can also check the `DiskSpaceReservedForMerge` metric in the `system.metrics` table, or in Graphite. You don’t need to do anything to fix this, since the issue will resolve itself once the large merges finish. If you find this unacceptable, you can restore the previous value for the `max_bytes_to_merge_at_max_space_in_pool` setting.

--   The format for marks in `Log` type tables that contain `Nullable` columns was changed in a backward incompatible way. If you have these tables, you should convert them to the `TinyLog` type before starting up the new server version. To do this, replace `ENGINE = Log` with `ENGINE = TinyLog` in the corresponding `.sql` file in the `metadata` directory. If your table doesn’t have `Nullable` columns or if the type of your table is not `Log`, then you don’t need to do anything.

 -   Removed the `experimental_allow_extended_storage_definition_syntax` setting. Now this feature is enabled by default.
 -   The `runningIncome` function was renamed to `runningDifferenceStartingWithFirstvalue` to avoid confusion.

-# Descripción general de la arquitectura ClickHouse {#overview-of-clickhouse-architecture}
-
-ClickHouse es un verdadero DBMS orientado a columnas. Los datos se almacenan por columnas y durante la ejecución de matrices (vectores o fragmentos de columnas). Siempre que sea posible, las operaciones se envían en matrices, en lugar de en valores individuales. Se llama “vectorized query execution,” y ayuda a reducir el costo del procesamiento de datos real.
-
-> Esta idea no es nada nuevo. Se remonta a la `APL` lenguaje de programación y sus descendientes: `A +`, `J`, `K`, y `Q`. La programación de matrices se utiliza en el procesamiento de datos científicos. Tampoco es esta idea algo nuevo en las bases de datos relacionales: por ejemplo, se usa en el `Vectorwise` sistema.
-
-Existen dos enfoques diferentes para acelerar el procesamiento de consultas: la ejecución de consultas vectorizadas y la generación de código en tiempo de ejecución. Este último elimina toda la indirección y el despacho dinámico. Ninguno de estos enfoques es estrictamente mejor que el otro. La generación de código de tiempo de ejecución puede ser mejor cuando fusiona muchas operaciones, utilizando así las unidades de ejecución de la CPU y la canalización. La ejecución de consultas vectorizadas puede ser menos práctica porque implica vectores temporales que deben escribirse en la memoria caché y leerse. Si los datos temporales no caben en la memoria caché L2, esto se convierte en un problema. Pero la ejecución de consultas vectorizadas utiliza más fácilmente las capacidades SIMD de la CPU. Un [documento de investigación](http://15721.courses.cs.cmu.edu/spring2016/papers/p5-sompolski.pdf) escrito por nuestros amigos muestra que es mejor combinar ambos enfoques. ClickHouse utiliza la ejecución de consultas vectorizadas y tiene un soporte inicial limitado para la generación de código en tiempo de ejecución.
-
-## Columna {#columns}
-
-`IColumn` interfaz se utiliza para representar columnas en la memoria (en realidad, fragmentos de columnas). Esta interfaz proporciona métodos auxiliares para la implementación de varios operadores relacionales. Casi todas las operaciones son inmutables: no modifican la columna original, sino que crean una nueva modificada. Por ejemplo, el `IColumn :: filter` método acepta una máscara de bytes de filtro. Se utiliza para el `WHERE` y `HAVING` operadores relacionales. Ejemplos adicionales: el `IColumn :: permute` para apoyar `ORDER BY`, el `IColumn :: cut` para apoyar `LIMIT`.
-
-Diversos `IColumn` aplicación (`ColumnUInt8`, `ColumnString`, y así sucesivamente) son responsables del diseño de memoria de las columnas. El diseño de memoria suele ser una matriz contigua. Para el tipo entero de columnas, es solo una matriz contigua, como `std :: vector`. Para `String` y `Array` columnas, son dos vectores: uno para todos los elementos de la matriz, colocados contiguamente, y un segundo para los desplazamientos al comienzo de cada matriz. También hay `ColumnConst` que almacena solo un valor en la memoria, pero parece una columna.
-
-## Campo {#field}
-
-Sin embargo, también es posible trabajar con valores individuales. Para representar un valor individual, el `Field` se utiliza. `Field` es sólo una unión discriminada de `UInt64`, `Int64`, `Float64`, `String` y `Array`. `IColumn` tiene el `operator[]` para obtener el valor n-ésimo como un `Field` y el `insert` método para agregar un `Field` al final de una columna. Estos métodos no son muy eficientes, ya que requieren tratar con temporal `Field` objetos que representan un valor individual. Hay métodos más eficientes, tales como `insertFrom`, `insertRangeFrom` y así sucesivamente.
-
-`Field` no tiene suficiente información sobre un tipo de datos específico para una tabla. Por ejemplo, `UInt8`, `UInt16`, `UInt32`, y `UInt64` todos están representados como `UInt64` en una `Field`.
-
-## Abstracciones con fugas {#leaky-abstractions}
-
-`IColumn` tiene métodos para transformaciones relacionales comunes de datos, pero no satisfacen todas las necesidades. Por ejemplo, `ColumnUInt64` no tiene un método para calcular la suma de dos columnas, y `ColumnString` no tiene un método para ejecutar una búsqueda de subcadena. Estas innumerables rutinas se implementan fuera de `IColumn`.
-
-Varias funciones en columnas se pueden implementar de una manera genérica, no eficiente utilizando `IColumn` para extraer `Field` valores, o de una manera especializada utilizando el conocimiento del diseño de la memoria interna de los datos en un `IColumn` aplicación. Se implementa mediante la conversión de funciones a un `IColumn` escriba y trate con la representación interna directamente. Por ejemplo, `ColumnUInt64` tiene el `getData` método que devuelve una referencia a una matriz interna, luego una rutina separada lee o llena esa matriz directamente. Tenemos “leaky abstractions” para permitir especializaciones eficientes de varias rutinas.
-
-## Tipos de datos {#data_types}
-
-`IDataType` es responsable de la serialización y deserialización: para leer y escribir fragmentos de columnas o valores individuales en formato binario o de texto. `IDataType` corresponde directamente a los tipos de datos en las tablas. Por ejemplo, hay `DataTypeUInt32`, `DataTypeDateTime`, `DataTypeString` y así sucesivamente.
-
-`IDataType` y `IColumn` están vagamente relacionados entre sí. Diferentes tipos de datos se pueden representar en la memoria por el mismo `IColumn` aplicación. Por ejemplo, `DataTypeUInt32` y `DataTypeDateTime` están representados por `ColumnUInt32` o `ColumnConstUInt32`. Además, el mismo tipo de datos se puede representar mediante `IColumn` aplicación. Por ejemplo, `DataTypeUInt8` puede ser representado por `ColumnUInt8` o `ColumnConstUInt8`.
-
-`IDataType` sólo almacena metadatos. Por ejemplo, `DataTypeUInt8` no almacena nada en absoluto (excepto vptr) y `DataTypeFixedString` tiendas solo `N` (el tamaño de las cadenas de tamaño fijo).
-
-`IDataType` tiene métodos auxiliares para varios formatos de datos. Los ejemplos son métodos para serializar un valor con posibles citas, para serializar un valor para JSON y para serializar un valor como parte del formato XML. No hay correspondencia directa con los formatos de datos. Por ejemplo, los diferentes formatos de datos `Pretty` y `TabSeparated` puede utilizar el mismo `serializeTextEscaped` método de ayuda de la `IDataType` interfaz.
-
-## Bloque {#block}
-
-A `Block` es un contenedor que representa un subconjunto (porción) de una tabla en la memoria. Es sólo un conjunto de triples: `(IColumn, IDataType, column name)`. Durante la ejecución de la consulta, los datos son procesados por `Block`s. Si tenemos un `Block`, tenemos datos (en el `IColumn` objeto), tenemos información sobre su tipo (en `IDataType`) que nos dice cómo lidiar con esa columna, y tenemos el nombre de la columna. Podría ser el nombre de columna original de la tabla o algún nombre artificial asignado para obtener resultados temporales de los cálculos.
-
-Cuando calculamos alguna función sobre columnas en un bloque, agregamos otra columna con su resultado al bloque, y no tocamos columnas para argumentos de la función porque las operaciones son inmutables. Más tarde, las columnas innecesarias se pueden eliminar del bloque, pero no se pueden modificar. Es conveniente para la eliminación de subexpresiones comunes.
-
-Se crean bloques para cada fragmento de datos procesado. Tenga en cuenta que para el mismo tipo de cálculo, los nombres y tipos de columna siguen siendo los mismos para diferentes bloques y solo cambian los datos de columna. Es mejor dividir los datos del bloque desde el encabezado del bloque porque los tamaños de bloque pequeños tienen una gran sobrecarga de cadenas temporales para copiar shared_ptrs y nombres de columna.
-
-## Bloquear flujos {#block-streams}
-
-Los flujos de bloques son para procesar datos. Usamos flujos de bloques para leer datos de algún lugar, realizar transformaciones de datos o escribir datos en algún lugar. `IBlockInputStream` tiene el `read` método para buscar el siguiente bloque mientras esté disponible. `IBlockOutputStream` tiene el `write` método para empujar el bloque en alguna parte.
-
-Los flujos son responsables de:
-
-1.  Leer o escribir en una mesa. La tabla solo devuelve una secuencia para leer o escribir bloques.
-2.  Implementación de formatos de datos. Por ejemplo, si desea enviar datos a un terminal en `Pretty` formato, crea un flujo de salida de bloque donde presiona bloques y los formatea.
-3.  Realización de transformaciones de datos. Digamos que tienes `IBlockInputStream` y desea crear una secuencia filtrada. Usted crea `FilterBlockInputStream` e inicializarlo con su transmisión. Luego, cuando tiras de un bloque de `FilterBlockInputStream`, extrae un bloque de su flujo, lo filtra y le devuelve el bloque filtrado. Las canalizaciones de ejecución de consultas se representan de esta manera.
-
-Hay transformaciones más sofisticadas. Por ejemplo, cuando tiras de `AggregatingBlockInputStream`, lee todos los datos de su origen, los agrega y, a continuación, devuelve un flujo de datos agregados para usted. Otro ejemplo: `UnionBlockInputStream` acepta muchas fuentes de entrada en el constructor y también una serie de subprocesos. Lanza múltiples hilos y lee de múltiples fuentes en paralelo.
-
-> Las secuencias de bloques usan el “pull” enfoque para controlar el flujo: cuando extrae un bloque de la primera secuencia, en consecuencia extrae los bloques requeridos de las secuencias anidadas, y toda la tubería de ejecución funcionará. Ni “pull” ni “push” es la mejor solución, porque el flujo de control está implícito y eso limita la implementación de varias características, como la ejecución simultánea de múltiples consultas (fusionando muchas tuberías). Esta limitación podría superarse con coroutines o simplemente ejecutando hilos adicionales que se esperan el uno al otro. Podemos tener más posibilidades si hacemos explícito el flujo de control: si localizamos la lógica para pasar datos de una unidad de cálculo a otra fuera de esas unidades de cálculo. Lea esto [artículo](http://journal.stuffwithstuff.com/2013/01/13/iteration-inside-and-out/) para más pensamientos.
-
-Debemos tener en cuenta que la canalización de ejecución de consultas crea datos temporales en cada paso. Tratamos de mantener el tamaño del bloque lo suficientemente pequeño para que los datos temporales se ajusten a la memoria caché de la CPU. Con esa suposición, escribir y leer datos temporales es casi gratis en comparación con otros cálculos. Podríamos considerar una alternativa, que es fusionar muchas operaciones en la tubería. Podría hacer que la tubería sea lo más corta posible y eliminar gran parte de los datos temporales, lo que podría ser una ventaja, pero también tiene inconvenientes. Por ejemplo, una canalización dividida facilita la implementación de almacenamiento en caché de datos intermedios, el robo de datos intermedios de consultas similares que se ejecutan al mismo tiempo y la fusión de canalizaciones para consultas similares.
-
-## Formato {#formats}
-
-Los formatos de datos se implementan con flujos de bloques. Hay “presentational” sólo es adecuado para la salida de datos al cliente, tales como `Pretty` formato, que proporciona sólo `IBlockOutputStream`. Y hay formatos de entrada / salida, como `TabSeparated` o `JSONEachRow`.
-
-También hay secuencias de filas: `IRowInputStream` y `IRowOutputStream`. Permiten pull/push datos por filas individuales, no por bloques. Y solo son necesarios para simplificar la implementación de formatos orientados a filas. Envoltura `BlockInputStreamFromRowInputStream` y `BlockOutputStreamFromRowOutputStream` le permite convertir flujos orientados a filas en flujos regulares orientados a bloques.
-
-## I/O {#io}
-
-Para la entrada / salida orientada a bytes, hay `ReadBuffer` y `WriteBuffer` clases abstractas. Se usan en lugar de C ++ `iostream`s. No se preocupe: cada proyecto maduro de C ++ está usando algo más que `iostream`s por buenas razones.
-
-`ReadBuffer` y `WriteBuffer` son solo un búfer contiguo y un cursor apuntando a la posición en ese búfer. Las implementaciones pueden poseer o no la memoria del búfer. Hay un método virtual para llenar el búfer con los siguientes datos (para `ReadBuffer`) o para vaciar el búfer en algún lugar (para `WriteBuffer`). Los métodos virtuales rara vez se llaman.
-
-Implementaciones de `ReadBuffer`/`WriteBuffer` se utilizan para trabajar con archivos y descriptores de archivos y sockets de red, para implementar la compresión (`CompressedWriteBuffer` is initialized with another WriteBuffer and performs compression before writing data to it), and for other purposes – the names `ConcatReadBuffer`, `LimitReadBuffer`, y `HashingWriteBuffer` hablar por sí mismos.
-
-Read / WriteBuffers solo se ocupan de bytes. Hay funciones de `ReadHelpers` y `WriteHelpers` archivos de encabezado para ayudar con el formato de entrada / salida. Por ejemplo, hay ayudantes para escribir un número en formato decimal.

-Veamos qué sucede cuando quieres escribir un conjunto de resultados en `JSON` formato a stdout. Tiene un conjunto de resultados listo para ser recuperado de `IBlockInputStream`. Usted crea `WriteBufferFromFileDescriptor(STDOUT_FILENO)` para escribir bytes en stdout. Usted crea `JSONRowOutputStream`, inicializado con eso `WriteBuffer` para escribir filas en `JSON` a stdout. Usted crea `BlockOutputStreamFromRowOutputStream` encima de él, para representarlo como `IBlockOutputStream`. Entonces usted llama `copyData` para transferir datos desde `IBlockInputStream` a `IBlockOutputStream` y todo funciona. Internamente, `JSONRowOutputStream` escribirá varios delimitadores JSON y llamará al `IDataType::serializeTextJSON` con una referencia a `IColumn` y el número de fila como argumentos. Consecuentemente, `IDataType::serializeTextJSON` llamará a un método de `WriteHelpers.h`: por ejemplo, `writeText` para tipos numéricos y `writeJSONString` para `DataTypeString`.
-
-## Tabla {#tables}
-
-El `IStorage` interfaz representa tablas. Las diferentes implementaciones de esa interfaz son diferentes motores de tabla. Los ejemplos son `StorageMergeTree`, `StorageMemory` y así sucesivamente. Las instancias de estas clases son solo tablas.
-
-Clave `IStorage` son `read` y `write`. También hay `alter`, `rename`, `drop` y así sucesivamente. El `read` método acepta los siguientes argumentos: el conjunto de columnas para leer de una tabla, el `AST` consulta a considerar, y el número deseado de flujos para devolver. Devuelve uno o varios `IBlockInputStream` objetos e información sobre la etapa de procesamiento de datos que se completó dentro de un motor de tablas durante la ejecución de la consulta.
-
-En la mayoría de los casos, el método de lectura solo es responsable de leer las columnas especificadas de una tabla, no de ningún procesamiento de datos adicional. Todo el procesamiento de datos adicional es realizado por el intérprete de consultas y está fuera de la responsabilidad de `IStorage`.
-
-Pero hay excepciones notables:
-
--   La consulta AST se pasa al `read` método, y el motor de tablas puede usarlo para derivar el uso del índice y leer menos datos de una tabla.
--   A veces, el motor de tablas puede procesar los datos a una etapa específica. Por ejemplo, `StorageDistributed` puede enviar una consulta a servidores remotos, pedirles que procesen datos a una etapa donde se puedan fusionar datos de diferentes servidores remotos y devolver esos datos preprocesados. El intérprete de consultas termina de procesar los datos.
-
-Tabla `read` método puede devolver múltiples `IBlockInputStream` objetos para permitir el procesamiento de datos en paralelo. Estos flujos de entrada de bloques múltiples pueden leer de una tabla en paralelo. A continuación, puede ajustar estas secuencias con varias transformaciones (como la evaluación de expresiones o el filtrado) que se pueden calcular de forma independiente y crear un `UnionBlockInputStream` encima de ellos, para leer desde múltiples flujos en paralelo.
-
-También hay `TableFunction`s. Estas son funciones que devuelven un `IStorage` objeto a utilizar en el `FROM` cláusula de una consulta.
-
-Para tener una idea rápida de cómo implementar su motor de tabla, vea algo simple, como `StorageMemory` o `StorageTinyLog`.
-
-> Como resultado de la `read` método, `IStorage` devoluciones `QueryProcessingStage` – information about what parts of the query were already calculated inside storage.
-
-## Analizador {#parsers}
-
-Un analizador de descenso recursivo escrito a mano analiza una consulta. Por ejemplo, `ParserSelectQuery` simplemente llama recursivamente a los analizadores subyacentes para varias partes de la consulta. Los analizadores crean un `AST`. El `AST` está representado por nodos, que son instancias de `IAST`.
-
-> Los generadores de analizadores no se utilizan por razones históricas.
-
-## Interprete {#interpreters}
-
-Los intérpretes son responsables de crear la canalización de ejecución de consultas `AST`. Hay intérpretes simples, como `InterpreterExistsQuery` y `InterpreterDropQuery` o el más sofisticado `InterpreterSelectQuery`. La canalización de ejecución de consultas es una combinación de flujos de entrada o salida de bloques. Por ejemplo, el resultado de interpretar el `SELECT` la consulta es la `IBlockInputStream` para leer el conjunto de resultados; el resultado de la consulta INSERT es el `IBlockOutputStream` para escribir datos para su inserción, y el resultado de interpretar el `INSERT SELECT` la consulta es la `IBlockInputStream` que devuelve un conjunto de resultados vacío en la primera lectura, pero que copia datos de `SELECT` a `INSERT` al mismo tiempo.
-
-`InterpreterSelectQuery` utilizar `ExpressionAnalyzer` y `ExpressionActions` maquinaria para el análisis de consultas y transformaciones. Aquí es donde se realizan la mayoría de las optimizaciones de consultas basadas en reglas. `ExpressionAnalyzer` es bastante complicado y debe reescribirse: se deben extraer varias transformaciones de consultas y optimizaciones para separar clases para permitir transformaciones modulares o consultas.
-
-## Función {#functions}
-
-Hay funciones ordinarias y funciones agregadas. Para las funciones agregadas, consulte la siguiente sección.
-
-Ordinary functions don't change the number of rows – they work as if they are processing each row independently. In fact, functions are not called for individual rows, but for `Block`de datos para implementar la ejecución de consultas vectorizadas.
-
-Hay algunas funciones diversas, como [BlockSize](../sql-reference/functions/other-functions.md#function-blocksize), [rowNumberInBlock](../sql-reference/functions/other-functions.md#function-rownumberinblock), y [runningAccumulate](../sql-reference/functions/other-functions.md#function-runningaccumulate), que explotan el procesamiento de bloques y violan la independencia de las filas.
-
-ClickHouse tiene una tipificación fuerte, por lo que no hay conversión de tipo implícita. Si una función no admite una combinación específica de tipos, produce una excepción. Pero las funciones pueden funcionar (estar sobrecargadas) para muchas combinaciones diferentes de tipos. Por ejemplo, el `plus` función (para implementar el `+` operador) funciona para cualquier combinación de tipos numéricos: `UInt8` + `Float32`, `UInt16` + `Int8` y así sucesivamente. Además, algunas funciones variadas pueden aceptar cualquier número de argumentos, como el `concat` función.
-
-Implementar una función puede ser un poco inconveniente porque una función distribuye explícitamente tipos de datos compatibles y `IColumns`. Por ejemplo, el `plus` La función tiene código generado por la creación de instancias de una plantilla de C ++ para cada combinación de tipos numéricos y argumentos izquierdo y derecho constantes o no constantes.
-
-Es un excelente lugar para implementar la generación de código en tiempo de ejecución para evitar la hinchazón del código de plantilla. Además, permite agregar funciones fusionadas como multiplicar-agregar fusionado o hacer comparaciones múltiples en una iteración de bucle.
-
-Debido a la ejecución de consultas vectorizadas, las funciones no se cortocircuitan. Por ejemplo, si escribe `WHERE f(x) AND g(y)`, ambos lados se calculan, incluso para las filas, cuando `f(x)` es cero (excepto cuando `f(x)` es una expresión constante cero). Pero si la selectividad del `f(x)` la condición es alta, y el cálculo de `f(x)` es mucho más barato que `g(y)`, es mejor implementar el cálculo de paso múltiple. Primero calcularía `f(x)`, a continuación, filtrar columnas por el resultado, y luego calcular `g(y)` solo para trozos de datos más pequeños y filtrados.
-
-## Funciones agregadas {#aggregate-functions}
-
-Las funciones agregadas son funciones con estado. Acumulan valores pasados en algún estado y le permiten obtener resultados de ese estado. Se gestionan con el `IAggregateFunction` interfaz. Los estados pueden ser bastante simples (el estado para `AggregateFunctionCount` es sólo una sola `UInt64` valor) o bastante complejo (el estado de `AggregateFunctionUniqCombined` es una combinación de una matriz lineal, una tabla hash, y un `HyperLogLog` estructura de datos probabilística).
-
-Los Estados están asignados en `Arena` (un grupo de memoria) para tratar con múltiples estados mientras se ejecuta una alta cardinalidad `GROUP BY` consulta. Los estados pueden tener un constructor y destructor no trivial: por ejemplo, los estados de agregación complicados pueden asignar memoria adicional ellos mismos. Requiere cierta atención a la creación y destrucción de estados y a la adecuada aprobación de su orden de propiedad y destrucción.
-
-Los estados de agregación se pueden serializar y deserializar para pasar a través de la red durante la ejecución de consultas distribuidas o para escribirlos en el disco donde no hay suficiente RAM. Incluso se pueden almacenar en una tabla con el `DataTypeAggregateFunction` para permitir la agregación incremental de datos.
-
-> El formato de datos serializados para los estados de función agregados no tiene versiones en este momento. Está bien si los estados agregados solo se almacenan temporalmente. Pero tenemos el `AggregatingMergeTree` motor de tabla para la agregación incremental, y la gente ya lo está utilizando en producción. Es la razón por la que se requiere compatibilidad con versiones anteriores al cambiar el formato serializado para cualquier función agregada en el futuro.
-
-## Servidor {#server}
-
-El servidor implementa varias interfaces diferentes:
-
--   Una interfaz HTTP para cualquier cliente extranjero.
--   Una interfaz TCP para el cliente nativo de ClickHouse y para la comunicación entre servidores durante la ejecución de consultas distribuidas.
--   Una interfaz para transferir datos para la replicación.
-
-Internamente, es solo un servidor multiproceso primitivo sin corutinas ni fibras. Dado que el servidor no está diseñado para procesar una alta tasa de consultas simples, sino para procesar una tasa relativamente baja de consultas complejas, cada uno de ellos puede procesar una gran cantidad de datos para análisis.
-
-El servidor inicializa el `Context` clase con el entorno necesario para la ejecución de consultas: la lista de bases de datos disponibles, usuarios y derechos de acceso, configuración, clústeres, la lista de procesos, el registro de consultas, etc. Los intérpretes utilizan este entorno.
-
-Mantenemos una compatibilidad total con versiones anteriores y posteriores para el protocolo TCP del servidor: los clientes antiguos pueden hablar con servidores nuevos y los nuevos clientes pueden hablar con servidores antiguos. Pero no queremos mantenerlo eternamente, y estamos eliminando el soporte para versiones antiguas después de aproximadamente un año.
-
-!!! note "Nota"
-    Para la mayoría de las aplicaciones externas, recomendamos usar la interfaz HTTP porque es simple y fácil de usar. El protocolo TCP está más estrechamente vinculado a las estructuras de datos internas: utiliza un formato interno para pasar bloques de datos y utiliza marcos personalizados para datos comprimidos. No hemos lanzado una biblioteca C para ese protocolo porque requiere vincular la mayor parte de la base de código ClickHouse, lo cual no es práctico.
-
-## Ejecución de consultas distribuidas {#distributed-query-execution}
-
-Los servidores de una configuración de clúster son en su mayoría independientes. Puede crear un `Distributed` en uno o todos los servidores de un clúster. El `Distributed` table does not store data itself – it only provides a “view” a todas las tablas locales en varios nodos de un clúster. Cuando se SELECCIONA desde un `Distributed` tabla, reescribe esa consulta, elige nodos remotos de acuerdo con la configuración de equilibrio de carga y les envía la consulta. El `Distributed` table solicita a los servidores remotos que procesen una consulta hasta una etapa en la que se pueden fusionar resultados intermedios de diferentes servidores. Luego recibe los resultados intermedios y los fusiona. La tabla distribuida intenta distribuir tanto trabajo como sea posible a servidores remotos y no envía muchos datos intermedios a través de la red.
-
-Las cosas se vuelven más complicadas cuando tiene subconsultas en cláusulas IN o JOIN, y cada una de ellas usa un `Distributed` tabla. Tenemos diferentes estrategias para la ejecución de estas consultas.
-
-No existe un plan de consulta global para la ejecución de consultas distribuidas. Cada nodo tiene su plan de consulta local para su parte del trabajo. Solo tenemos una ejecución simple de consultas distribuidas de un solo paso: enviamos consultas para nodos remotos y luego fusionamos los resultados. Pero esto no es factible para consultas complicadas con alta cardinalidad GROUP BY o con una gran cantidad de datos temporales para JOIN. En tales casos, necesitamos “reshuffle” datos entre servidores, lo que requiere una coordinación adicional. ClickHouse no admite ese tipo de ejecución de consultas, y tenemos que trabajar en ello.
-
-## Árbol de fusión {#merge-tree}
-
-`MergeTree` es una familia de motores de almacenamiento que admite la indexación por clave principal. La clave principal puede ser una tupla arbitraria de columnas o expresiones. Datos en un `MergeTree` se almacena en “parts”. Cada parte almacena los datos en el orden de la clave principal, por lo que la tupla de la clave principal ordena los datos lexicográficamente. Todas las columnas de la tabla se almacenan en `column.bin` archivos en estas partes. Los archivos consisten en bloques comprimidos. Cada bloque suele ser de 64 KB a 1 MB de datos sin comprimir, dependiendo del tamaño del valor promedio. Los bloques constan de valores de columna colocados contiguamente uno tras otro. Los valores de columna están en el mismo orden para cada columna (la clave principal define el orden), por lo que cuando itera por muchas columnas, obtiene valores para las filas correspondientes.
-
-La clave principal en sí es “sparse”. No aborda cada fila, sino solo algunos rangos de datos. Separado `primary.idx` file tiene el valor de la clave principal para cada fila N-ésima, donde se llama N `index_granularity` (generalmente, N = 8192). Además, para cada columna, tenemos `column.mrk` archivos con “marks,” que son desplazamientos a cada fila N-ésima en el archivo de datos. Cada marca es un par: el desplazamiento en el archivo al comienzo del bloque comprimido y el desplazamiento en el bloque descomprimido al comienzo de los datos. Por lo general, los bloques comprimidos están alineados por marcas, y el desplazamiento en el bloque descomprimido es cero. Datos para `primary.idx` siempre reside en la memoria, y los datos para `column.mrk` archivos se almacena en caché.
-
-Cuando vamos a leer algo de una parte en `MergeTree` miramos `primary.idx` datos y localice rangos que podrían contener datos solicitados, luego mire `column.mrk` datos y calcular compensaciones para dónde comenzar a leer esos rangos. Debido a la escasez, el exceso de datos puede ser leído. ClickHouse no es adecuado para una gran carga de consultas de puntos simples, porque todo el rango con `index_granularity` se deben leer filas para cada clave, y todo el bloque comprimido debe descomprimirse para cada columna. Hicimos que el índice sea disperso porque debemos poder mantener billones de filas por único servidor sin un consumo de memoria notable para el índice. Además, debido a que la clave principal es escasa, no es única: no puede verificar la existencia de la clave en la tabla en el momento de INSERTAR. Podría tener muchas filas con la misma clave en una tabla.
-
-Cuando `INSERT` un montón de datos en `MergeTree`, ese grupo está ordenado por orden de clave primaria y forma una nueva parte. Hay subprocesos de fondo que seleccionan periódicamente algunas partes y las fusionan en una sola parte ordenada para mantener el número de partes relativamente bajo. Es por eso que se llama `MergeTree`. Por supuesto, la fusión conduce a “write amplification”. Todas las partes son inmutables: solo se crean y eliminan, pero no se modifican. Cuando se ejecuta SELECT, contiene una instantánea de la tabla (un conjunto de partes). Después de la fusión, también mantenemos las piezas viejas durante algún tiempo para facilitar la recuperación después de la falla, por lo que si vemos que alguna parte fusionada probablemente esté rota, podemos reemplazarla con sus partes de origen.
-
-`MergeTree` no es un árbol de LSM porque no contiene “memtable” y “log”: inserted data is written directly to the filesystem. This makes it suitable only to INSERT data in batches, not by individual row and not very frequently – about once per second is ok, but a thousand times a second is not. We did it this way for simplicity's sake, and because we are already inserting data in batches in our applications.
-
-> Las tablas MergeTree solo pueden tener un índice (primario): no hay índices secundarios. Sería bueno permitir múltiples representaciones físicas bajo una tabla lógica, por ejemplo, para almacenar datos en más de un orden físico o incluso para permitir representaciones con datos preagregados junto con datos originales.
-
-Hay motores MergeTree que están haciendo un trabajo adicional durante las fusiones en segundo plano. Los ejemplos son `CollapsingMergeTree` y `AggregatingMergeTree`. Esto podría tratarse como soporte especial para actualizaciones. Tenga en cuenta que estas no son actualizaciones reales porque los usuarios generalmente no tienen control sobre el tiempo en que se ejecutan las fusiones en segundo plano y los datos en un `MergeTree` casi siempre se almacena en más de una parte, no en forma completamente fusionada.
-
-## Replicación {#replication}
-
-La replicación en ClickHouse se puede configurar por tabla. Podría tener algunas tablas replicadas y otras no replicadas en el mismo servidor. También puede tener tablas replicadas de diferentes maneras, como una tabla con replicación de dos factores y otra con replicación de tres factores.
-
-La replicación se implementa en el `ReplicatedMergeTree` motor de almacenamiento. El camino en `ZooKeeper` se especifica como un parámetro para el motor de almacenamiento. Todas las tablas con la misma ruta en `ZooKeeper` se convierten en réplicas entre sí: sincronizan sus datos y mantienen la coherencia. Las réplicas se pueden agregar y eliminar dinámicamente simplemente creando o soltando una tabla.
-
-La replicación utiliza un esquema multi-maestro asíncrono. Puede insertar datos en cualquier réplica que tenga una sesión con `ZooKeeper`, y los datos se replican en todas las demás réplicas de forma asíncrona. Como ClickHouse no admite UPDATE, la replicación está libre de conflictos. Como no hay reconocimiento de quórum de inserciones, los datos recién insertados pueden perderse si un nodo falla.
-
-Los metadatos para la replicación se almacenan en ZooKeeper. Hay un registro de replicación que enumera las acciones que se deben realizar. Las acciones son: obtener parte; fusionar partes; soltar una partición, etc. Cada réplica copia el registro de replicación en su cola y, a continuación, ejecuta las acciones desde la cola. Por ejemplo, en la inserción, el “get the part” la acción se crea en el registro y cada réplica descarga esa parte. Las fusiones se coordinan entre réplicas para obtener resultados idénticos en bytes. Todas las piezas se combinan de la misma manera en todas las réplicas. Se logra eligiendo una réplica como líder, y esa réplica inicia fusiones y escrituras “merge parts” acciones al registro.
-
-La replicación es física: solo las partes comprimidas se transfieren entre nodos, no consultas. Las fusiones se procesan en cada réplica de forma independiente en la mayoría de los casos para reducir los costos de red al evitar la amplificación de la red. Las piezas combinadas grandes se envían a través de la red solo en casos de retraso de replicación significativo.
-
-Además, cada réplica almacena su estado en ZooKeeper como el conjunto de piezas y sus sumas de comprobación. Cuando el estado en el sistema de archivos local difiere del estado de referencia en ZooKeeper, la réplica restaura su coherencia descargando partes faltantes y rotas de otras réplicas. Cuando hay algunos datos inesperados o rotos en el sistema de archivos local, ClickHouse no los elimina, sino que los mueve a un directorio separado y los olvida.
-
-!!! note "Nota"
-    El clúster ClickHouse consta de fragmentos independientes y cada fragmento consta de réplicas. El clúster es **no elástico**, por lo tanto, después de agregar un nuevo fragmento, los datos no se reequilibran automáticamente entre fragmentos. En su lugar, se supone que la carga del clúster debe ajustarse para que sea desigual. Esta implementación le da más control, y está bien para clústeres relativamente pequeños, como decenas de nodos. Pero para los clústeres con cientos de nodos que estamos utilizando en producción, este enfoque se convierte en un inconveniente significativo. Debemos implementar un motor de tablas que abarque todo el clúster con regiones replicadas dinámicamente que puedan dividirse y equilibrarse entre clústeres automáticamente.

-# Cómo construir ClickHouse para el desarrollo {#how-to-build-clickhouse-for-development}
-
-El siguiente tutorial se basa en el sistema Ubuntu Linux.
-Con los cambios apropiados, también debería funcionar en cualquier otra distribución de Linux.
-Plataformas compatibles: x86_64 y AArch64. El soporte para Power9 es experimental.
-
-## Instalar Git, CMake, Python y Ninja {#install-git-cmake-python-and-ninja}
-
-``` bash
-$ sudo apt-get install git cmake python ninja-build
-```
-
-O cmake3 en lugar de cmake en sistemas más antiguos.
-
-## Instalar GCC 10 {#install-gcc-10}
-
-Hay varias formas de hacer esto.
-
-### Instalar desde un paquete PPA {#install-from-a-ppa-package}
-
-``` bash
-$ sudo apt-get install software-properties-common
-$ sudo apt-add-repository ppa:ubuntu-toolchain-r/test
-$ sudo apt-get update
-$ sudo apt-get install gcc-10 g++-10
-```
-
-### Instalar desde fuentes {#install-from-sources}
-
-Mira [Sistema abierto.](https://github.com/ClickHouse/ClickHouse/blob/master/utils/ci/build-gcc-from-sources.sh)
-
-## Usar GCC 10 para compilaciones {#use-gcc-10-for-builds}
-
-``` bash
-$ export CC=gcc-10
-$ export CXX=g++-10
-```
-
-## Fuentes de ClickHouse de pago {#checkout-clickhouse-sources}
-
-``` bash
-$ git clone --recursive git@github.com:ClickHouse/ClickHouse.git
-```
-
-o
-
-``` bash
-$ git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-```
-
-## Construir ClickHouse {#build-clickhouse}
-
-``` bash
-$ cd ClickHouse
-$ mkdir build
-$ cd build
-$ cmake ..
-$ ninja
-$ cd ..
-```
-
-Para crear un ejecutable, ejecute `ninja clickhouse`.
-Esto creará el `programs/clickhouse` ejecutable, que se puede usar con `client` o `server` argumento.
-
-# Cómo construir ClickHouse en cualquier Linux {#how-to-build-clickhouse-on-any-linux}
-
-La compilación requiere los siguientes componentes:
-
--   Git (se usa solo para verificar las fuentes, no es necesario para la compilación)
--   CMake 3.10 o más reciente
--   Ninja (recomendado) o Hacer
--   Compilador de C ++: gcc 10 o clang 8 o más reciente
--   Enlazador: lld u oro (el clásico GNU ld no funcionará)
--   Python (solo se usa dentro de la compilación LLVM y es opcional)
-
-Si todos los componentes están instalados, puede compilar de la misma manera que los pasos anteriores.
-
-Ejemplo para Ubuntu Eoan:
-
-    sudo apt update
-    sudo apt install git cmake ninja-build g++ python
-    git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-    mkdir build && cd build
-    cmake ../ClickHouse
-    ninja
-
-Ejemplo de OpenSUSE Tumbleweed:
-
-    sudo zypper install git cmake ninja gcc-c++ python lld
-    git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-    mkdir build && cd build
-    cmake ../ClickHouse
-    ninja
-
-Ejemplo de Fedora Rawhide:
-
-    sudo yum update
-    yum --nogpg install git cmake make gcc-c++ python3
-    git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-    mkdir build && cd build
-    cmake ../ClickHouse
-    make -j $(nproc)
-
-# No tienes que construir ClickHouse {#you-dont-have-to-build-clickhouse}
-
-ClickHouse está disponible en binarios y paquetes preconstruidos. Los binarios son portátiles y se pueden ejecutar en cualquier tipo de Linux.
-
-Están diseñados para lanzamientos estables, preestablecidos y de prueba, siempre que para cada compromiso con el maestro y para cada solicitud de extracción.
-
-Para encontrar la construcción más fresca de `master`, ir a [se compromete página](https://github.com/ClickHouse/ClickHouse/commits/master), haga clic en la primera marca de verificación verde o cruz roja cerca de confirmar, y haga clic en “Details” enlace justo después “ClickHouse Build Check”.

-toc_title: "La instrucci\xF3n para desarrolladores de ClickHouse para principiantes"
----
-
-La construcción de ClickHouse es compatible con Linux, FreeBSD y Mac OS X.
-
-# Si utiliza Windows {#if-you-use-windows}
-
-Si usa Windows, necesita crear una máquina virtual con Ubuntu. Para comenzar a trabajar con una máquina virtual, instale VirtualBox. Puede descargar Ubuntu desde el sitio web: https://www.ubuntu.com/#download. Por favor, cree una máquina virtual a partir de la imagen descargada (debe reservar al menos 4 GB de RAM para ello). Para ejecutar un terminal de línea de comandos en Ubuntu, busque un programa que contenga la palabra “terminal” en su nombre (gnome-terminal, konsole etc.) o simplemente presione Ctrl + Alt + T.
-
-# Si utiliza un sistema de 32 bits {#if-you-use-a-32-bit-system}
-
-ClickHouse no puede funcionar ni construir en un sistema de 32 bits. Debe adquirir acceso a un sistema de 64 bits y puede continuar leyendo.
-
-# Creación de un repositorio en GitHub {#creating-a-repository-on-github}
-
-Para comenzar a trabajar con el repositorio de ClickHouse, necesitará una cuenta de GitHub.
-
-Probablemente ya tenga uno, pero si no lo hace, regístrese en https://github.com . En caso de que no tenga claves SSH, debe generarlas y luego cargarlas en GitHub. Es necesario para enviar a través de sus parches. También es posible usar las mismas claves SSH que usa con cualquier otro servidor SSH, probablemente ya las tenga.
-
-Cree una bifurcación del repositorio ClickHouse. Para hacerlo por favor haga clic en el “fork” botón en la esquina superior derecha en https://github.com/ClickHouse/ClickHouse . Se bifurcará su propia copia de ClickHouse/ClickHouse a su cuenta.
-
-El proceso de desarrollo consiste en comprometer primero los cambios previstos en su bifurcación de ClickHouse y luego crear un “pull request” para que estos cambios sean aceptados en el repositorio principal (ClickHouse / ClickHouse).
-
-Para trabajar con repositorios git, instale `git`.
-
-Para hacer eso en Ubuntu, ejecutaría en la terminal de línea de comandos:
-
-    sudo apt update
-    sudo apt install git
-
-Puede encontrar un breve manual sobre el uso de Git aquí: https://education.github.com/git-cheat-sheet-education.pdf .
-Para obtener un manual detallado sobre Git, consulte https://git-scm.com/book/en/v2 .
-
-# Clonación de un repositorio en su máquina de desarrollo {#cloning-a-repository-to-your-development-machine}
-
-A continuación, debe descargar los archivos fuente en su máquina de trabajo. Esto se llama “to clone a repository” porque crea una copia local del repositorio en su máquina de trabajo.
-
-En el terminal de línea de comandos, ejecute:
-
-    git clone --recursive git@github.com:your_github_username/ClickHouse.git
-    cd ClickHouse
-
-Nota: por favor, sustituye *your_github_username* con lo que es apropiado!
-
-Este comando creará un directorio `ClickHouse` que contiene la copia de trabajo del proyecto.
-
-Es importante que la ruta al directorio de trabajo no contenga espacios en blanco, ya que puede ocasionar problemas con la ejecución del sistema de compilación.
-
-Tenga en cuenta que el repositorio ClickHouse utiliza `submodules`. That is what the references to additional repositories are called (i.e. external libraries on which the project depends). It means that when cloning the repository you need to specify the `--recursive` como en el ejemplo anterior. Si el repositorio se ha clonado sin submódulos, para descargarlos debe ejecutar lo siguiente:
-
-    git submodule init
-    git submodule update
-
-Puede verificar el estado con el comando: `git submodule status`.
-
-Si recibe el siguiente mensaje de error:
-
-    Permission denied (publickey).
-    fatal: Could not read from remote repository.
-
-    Please make sure you have the correct access rights
-    and the repository exists.
-
-Por lo general, significa que faltan las claves SSH para conectarse a GitHub. Estas teclas se encuentran normalmente en `~/.ssh`. Para que las claves SSH sean aceptadas, debe cargarlas en la sección de configuración de la interfaz de usuario de GitHub.
-
-También puede clonar el repositorio a través del protocolo https:
-
-    git clone https://github.com/ClickHouse/ClickHouse.git
-
-Sin embargo, esto no le permitirá enviar los cambios al servidor. Aún puede usarlo temporalmente y agregar las claves SSH más tarde reemplazando la dirección remota del repositorio con `git remote` comando.
-
-También puede agregar la dirección original del repositorio de ClickHouse a su repositorio local para extraer actualizaciones desde allí:
-
-    git remote add upstream git@github.com:ClickHouse/ClickHouse.git
-
-Después de ejecutar con éxito este comando, podrá extraer actualizaciones del repositorio principal de ClickHouse ejecutando `git pull upstream master`.
-
-## Trabajar con submódulos {#working-with-submodules}
-
-Trabajar con submódulos en git podría ser doloroso. Los siguientes comandos ayudarán a administrarlo:
-
-    # ! each command accepts --recursive
-    # Update remote URLs for submodules. Barely rare case
-    git submodule sync
-    # Add new submodules
-    git submodule init
-    # Update existing submodules to the current state
-    git submodule update
-    # Two last commands could be merged together
-    git submodule update --init
-
-Los siguientes comandos le ayudarían a restablecer todos los submódulos al estado inicial (!¡ADVERTENCIA! - cualquier cambio en el interior será eliminado):
-
-    # Synchronizes submodules' remote URL with .gitmodules
-    git submodule sync --recursive
-    # Update the registered submodules with initialize not yet initialized
-    git submodule update --init --recursive
-    # Reset all changes done after HEAD
-    git submodule foreach git reset --hard
-    # Clean files from .gitignore
-    git submodule foreach git clean -xfd
-    # Repeat last 4 commands for all submodule
-    git submodule foreach git submodule sync --recursive
-    git submodule foreach git submodule update --init --recursive
-    git submodule foreach git submodule foreach git reset --hard
-    git submodule foreach git submodule foreach git clean -xfd
-
-# Sistema de construcción {#build-system}
-
-ClickHouse utiliza CMake y Ninja para la construcción.
-
-CMake - un sistema de meta-construcción que puede generar archivos Ninja (tareas de construcción).
-Ninja: un sistema de compilación más pequeño con un enfoque en la velocidad utilizada para ejecutar esas tareas generadas por cmake.
-
-Para instalar en Ubuntu, Debian o Mint run `sudo apt install cmake ninja-build`.
-
-En CentOS, RedHat se ejecuta `sudo yum install cmake ninja-build`.
-
-Si usa Arch o Gentoo, probablemente lo sepa usted mismo cómo instalar CMake.
-
-Para instalar CMake y Ninja en Mac OS X, primero instale Homebrew y luego instale todo lo demás a través de brew:
-
-    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-    brew install cmake ninja
-
-A continuación, verifique la versión de CMake: `cmake --version`. Si está por debajo de 3.3, debe instalar una versión más reciente desde el sitio web: https://cmake.org/download/.
-
-# Bibliotecas externas opcionales {#optional-external-libraries}
-
-ClickHouse utiliza varias bibliotecas externas para la construcción. Todos ellos no necesitan ser instalados por separado, ya que se construyen junto con ClickHouse a partir de las fuentes ubicadas en los submódulos. Puede consultar la lista en `contrib`.
-
-# Compilador de C ++ {#c-compiler}
-
-Los compiladores GCC a partir de la versión 10 y Clang versión 8 o superior son compatibles para construir ClickHouse.
-
-Las compilaciones oficiales de Yandex actualmente usan GCC porque genera código de máquina de un rendimiento ligeramente mejor (con una diferencia de hasta varios por ciento según nuestros puntos de referencia). Y Clang es más conveniente para el desarrollo generalmente. Sin embargo, nuestra plataforma de integración continua (CI) ejecuta verificaciones de aproximadamente una docena de combinaciones de compilación.
-
-Para instalar GCC en Ubuntu, ejecute: `sudo apt install gcc g++`
-
-Compruebe la versión de gcc: `gcc --version`. Si está por debajo de 9, siga las instrucciones aquí: https://clickhouse.tech/docs/es/development/build/#install-gcc-10.
-
-La compilación de Mac OS X solo es compatible con Clang. Sólo tiene que ejecutar `brew install llvm`
-
-Si decide utilizar Clang, también puede instalar `libc++` y `lld` si usted sabe lo que es. Utilizar `ccache` también se recomienda.
-
-# El proceso de construcción {#the-building-process}
-
-Ahora que está listo para construir ClickHouse, le recomendamos que cree un directorio separado `build` dentro `ClickHouse` que contendrá todos los de la generación de artefactos:
-
-    mkdir build
-    cd build
-
-Puede tener varios directorios diferentes (build_release, build_debug, etc.) para diferentes tipos de construcción.
-
-Mientras que dentro de la `build` directorio, configure su compilación ejecutando CMake. Antes de la primera ejecución, debe definir variables de entorno que especifiquen el compilador (compilador gcc versión 10 en este ejemplo).
-
-Linux:
-
-    export CC=gcc-10 CXX=g++-10
-    cmake ..
-
-Mac OS X:
-
-    export CC=clang CXX=clang++
-    cmake ..
-
-El `CC` variable especifica el compilador para C (abreviatura de C Compiler), y `CXX` variable indica qué compilador de C ++ se usará para compilar.
-
-Para una construcción más rápida, puede recurrir al `debug` tipo de compilación: una compilación sin optimizaciones. Para ese suministro el siguiente parámetro `-D CMAKE_BUILD_TYPE=Debug`:
-
-    cmake -D CMAKE_BUILD_TYPE=Debug ..
-
-Puede cambiar el tipo de compilación ejecutando este comando en el `build` directorio.
-
-Ejecutar ninja para construir:
-
-    ninja clickhouse-server clickhouse-client
-
-Solo los binarios requeridos se van a construir en este ejemplo.
-
-Si necesita construir todos los binarios (utilidades y pruebas), debe ejecutar ninja sin parámetros:
-
-    ninja
-
-La compilación completa requiere aproximadamente 30 GB de espacio libre en disco o 15 GB para construir los binarios principales.
-
-Cuando hay una gran cantidad de RAM disponible en la máquina de compilación, debe limitar el número de tareas de compilación que se ejecutan en paralelo con `-j` parámetro:
-
-    ninja -j 1 clickhouse-server clickhouse-client
-
-En máquinas con 4GB de RAM, se recomienda especificar 1, para 8GB de RAM `-j 2` se recomienda.
-
-Si recibe el mensaje: `ninja: error: loading 'build.ninja': No such file or directory`, significa que la generación de una configuración de compilación ha fallado y necesita inspeccionar el mensaje anterior.
-
-Cuando se inicie correctamente el proceso de construcción, verá el progreso de la compilación: el número de tareas procesadas y el número total de tareas.
-
-Al crear mensajes sobre archivos protobuf en la biblioteca libhdfs2, como `libprotobuf WARNING` puede aparecer. Afectan a nada y son seguros para ser ignorado.
-
-Tras la compilación exitosa, obtienes un archivo ejecutable `ClickHouse/<build_dir>/programs/clickhouse`:
-
-    ls -l programs/clickhouse
-
-# Ejecución del ejecutable construido de ClickHouse {#running-the-built-executable-of-clickhouse}
-
-Para ejecutar el servidor bajo el usuario actual, debe navegar hasta `ClickHouse/programs/server/` (situado fuera de `build`) y ejecutar:
-
-    ../../build/programs/clickhouse server
-
-En este caso, ClickHouse usará archivos de configuración ubicados en el directorio actual. Puede ejecutar `clickhouse server` desde cualquier directorio que especifique la ruta a un archivo de configuración como un parámetro de línea de comandos `--config-file`.
-
-Para conectarse a ClickHouse con clickhouse-client en otro terminal, vaya a `ClickHouse/build/programs/` y ejecutar `./clickhouse client`.
-
-Si usted consigue `Connection refused` mensaje en Mac OS X o FreeBSD, intente especificar la dirección de host 127.0.0.1:
-
-    clickhouse client --host 127.0.0.1
-
-Puede reemplazar la versión de producción del binario ClickHouse instalado en su sistema con su binario ClickHouse personalizado. Para ello, instale ClickHouse en su máquina siguiendo las instrucciones del sitio web oficial. A continuación, ejecute lo siguiente:
-
-    sudo service clickhouse-server stop
-    sudo cp ClickHouse/build/programs/clickhouse /usr/bin/
-    sudo service clickhouse-server start
-
-Tenga en cuenta que `clickhouse-client`, `clickhouse-server` y otros son enlaces simbólicos a los comúnmente compartidos `clickhouse` binario.
-
-También puede ejecutar su binario ClickHouse personalizado con el archivo de configuración del paquete ClickHouse instalado en su sistema:
-
-    sudo service clickhouse-server stop
-    sudo -u clickhouse ClickHouse/build/programs/clickhouse server --config-file /etc/clickhouse-server/config.xml
-
-# IDE (entorno de desarrollo integrado) {#ide-integrated-development-environment}
-
-Si no sabe qué IDE usar, le recomendamos que use CLion. CLion es un software comercial, pero ofrece un período de prueba gratuito de 30 días. También es gratuito para los estudiantes. CLion se puede usar tanto en Linux como en Mac OS X.
-
-KDevelop y QTCreator son otras excelentes alternativas de un IDE para desarrollar ClickHouse. KDevelop viene como un IDE muy útil aunque inestable. Si KDevelop se bloquea después de un tiempo al abrir el proyecto, debe hacer clic “Stop All” botón tan pronto como se ha abierto la lista de archivos del proyecto. Después de hacerlo, KDevelop debería estar bien para trabajar.
-
-Como editores de código simples, puede usar Sublime Text o Visual Studio Code, o Kate (todos los cuales están disponibles en Linux).
-
-Por si acaso, vale la pena mencionar que CLion crea `build` por sí mismo, también por sí mismo selecciona `debug` para el tipo de compilación, para la configuración usa una versión de CMake que está definida en CLion y no la instalada por usted, y finalmente, CLion usará `make` para ejecutar tareas de compilación en lugar de `ninja`. Este es un comportamiento normal, solo tenlo en cuenta para evitar confusiones.

-# Datos de prueba {#test-data}
-
-El desarrollo de ClickHouse a menudo requiere cargar conjuntos de datos realistas. Es particularmente importante para las pruebas de rendimiento. Tenemos un conjunto especialmente preparado de datos anónimos de Yandex.Métrica. Se requiere, además, unos 3 GB de espacio libre en disco. Tenga en cuenta que estos datos no son necesarios para realizar la mayoría de las tareas de desarrollo.

-# Creación de solicitud de extracción {#creating-pull-request}
-
-Navega a tu repositorio de fork en la interfaz de usuario de GitHub. Si ha estado desarrollando en una sucursal, debe seleccionar esa sucursal. Habrá un “Pull request” botón situado en la pantalla. En esencia, esto significa “create a request for accepting my changes into the main repository”.
-
-Se puede crear una solicitud de extracción incluso si el trabajo aún no se ha completado. En este caso, por favor ponga la palabra “WIP” (trabajo en curso) al comienzo del título, se puede cambiar más tarde. Esto es útil para la revisión cooperativa y la discusión de los cambios, así como para ejecutar todas las pruebas disponibles. Es importante que proporcione una breve descripción de sus cambios, que más tarde se utilizará para generar registros de cambios de lanzamiento.
-
-Las pruebas comenzarán tan pronto como los empleados de Yandex etiqueten su PR con una etiqueta “can be tested”. The results of some first checks (e.g. code style) will come in within several minutes. Build check results will arrive within half an hour. And the main set of tests will report itself within an hour.
-
-El sistema preparará compilaciones binarias ClickHouse para su solicitud de extracción individualmente. Para recuperar estas compilaciones, haga clic en “Details” junto al link “ClickHouse build check” en la lista de cheques. Allí encontrará enlaces directos a la construcción.deb paquetes de ClickHouse que puede implementar incluso en sus servidores de producción (si no tiene miedo).
-
-Lo más probable es que algunas de las compilaciones fallen las primeras veces. Esto se debe al hecho de que verificamos las compilaciones tanto con gcc como con clang, con casi todas las advertencias existentes (siempre con el `-Werror` bandera) habilitado para sonido. En esa misma página, puede encontrar todos los registros de compilación para que no tenga que compilar ClickHouse de todas las formas posibles.

-# Cómo escribir código C ++ {#how-to-write-c-code}
-
-## Recomendaciones generales {#general-recommendations}
-
-**1.** Las siguientes son recomendaciones, no requisitos.
-
-**2.** Si está editando código, tiene sentido seguir el formato del código existente.
-
-**3.** El estilo de código es necesario para la coherencia. La consistencia facilita la lectura del código y también facilita la búsqueda del código.
-
-**4.** Muchas de las reglas no tienen razones lógicas; están dictadas por prácticas establecidas.
-
-## Formatear {#formatting}
-
-**1.** La mayor parte del formato se realizará automáticamente por `clang-format`.
-
-**2.** Las sangrías son 4 espacios. Configure el entorno de desarrollo para que una pestaña agregue cuatro espacios.
-
-**3.** Abrir y cerrar llaves deben estar en una línea separada.
-
-``` cpp
-inline void readBoolText(bool & x, ReadBuffer & buf)
-{
-    char tmp = '0';
-    readChar(tmp, buf);
-    x = tmp != '0';
-}
-```
-
-**4.** Si todo el cuerpo de la función es `statement`, se puede colocar en una sola línea. Coloque espacios alrededor de llaves (además del espacio al final de la línea).
-
-``` cpp
-inline size_t mask() const                { return buf_size() - 1; }
-inline size_t place(HashValue x) const    { return x & mask(); }
-```
-
-**5.** Para funciones. No coloque espacios alrededor de los corchetes.
-
-``` cpp
-void reinsert(const Value & x)
-```
-
-``` cpp
-memcpy(&buf[place_value], &x, sizeof(x));
-```
-
-**6.** En `if`, `for`, `while` y otras expresiones, se inserta un espacio delante del corchete de apertura (a diferencia de las llamadas a funciones).
-
-``` cpp
-for (size_t i = 0; i < rows; i += storage.index_granularity)
-```
-
-**7.** Agregar espacios alrededor de los operadores binarios (`+`, `-`, `*`, `/`, `%`, …) and the ternary operator `?:`.
-
-``` cpp
-UInt16 year = (s[0] - '0') * 1000 + (s[1] - '0') * 100 + (s[2] - '0') * 10 + (s[3] - '0');
-UInt8 month = (s[5] - '0') * 10 + (s[6] - '0');
-UInt8 day = (s[8] - '0') * 10 + (s[9] - '0');
-```
-
-**8.** Si se introduce un avance de línea, coloque al operador en una nueva línea y aumente la sangría antes de ella.
-
-``` cpp
-if (elapsed_ns)
-    message << " ("
-        << rows_read_on_server * 1000000000 / elapsed_ns << " rows/s., "
-        << bytes_read_on_server * 1000.0 / elapsed_ns << " MB/s.) ";
-```
-
-**9.** Puede utilizar espacios para la alineación dentro de una línea, si lo desea.
-
-``` cpp
-dst.ClickLogID         = click.LogID;
-dst.ClickEventID       = click.EventID;
-dst.ClickGoodEvent     = click.GoodEvent;
-```
-
-**10.** No use espacios alrededor de los operadores `.`, `->`.
-
-Si es necesario, el operador se puede envolver a la siguiente línea. En este caso, el desplazamiento frente a él aumenta.
-
-**11.** No utilice un espacio para separar los operadores unarios (`--`, `++`, `*`, `&`, …) from the argument.
-
-**12.** Pon un espacio después de una coma, pero no antes. La misma regla se aplica a un punto y coma dentro de un `for` expresion.
-
-**13.** No utilice espacios para separar el `[]` operador.
-
-**14.** En un `template <...>` expresión, use un espacio entre `template` y `<`; sin espacios después de `<` o antes `>`.
-
-``` cpp
-template <typename TKey, typename TValue>
-struct AggregatedStatElement
-{}
-```
-
-**15.** En clases y estructuras, escribe `public`, `private`, y `protected` en el mismo nivel que `class/struct`, y sangrar el resto del código.
-
-``` cpp
-template <typename T>
-class MultiVersion
-{
-public:
-    /// Version of object for usage. shared_ptr manage lifetime of version.
-    using Version = std::shared_ptr<const T>;
-    ...
-}
-```
-
-**16.** Si el mismo `namespace` se usa para todo el archivo, y no hay nada más significativo, no es necesario un desplazamiento dentro `namespace`.
-
-**17.** Si el bloque para un `if`, `for`, `while`, u otra expresión consiste en una sola `statement`, las llaves son opcionales. Coloque el `statement` en una línea separada, en su lugar. Esta regla también es válida para `if`, `for`, `while`, …
-
-Pero si el interior `statement` contiene llaves o `else`, el bloque externo debe escribirse entre llaves.
-
-``` cpp
-/// Finish write.
-for (auto & stream : streams)
-    stream.second->finalize();
-```
-
-**18.** No debería haber espacios al final de las líneas.
-
-**19.** Los archivos de origen están codificados en UTF-8.
-
-**20.** Los caracteres no ASCII se pueden usar en literales de cadena.
-
-``` cpp
-<< ", " << (timer.elapsed() / chunks_stats.hits) << " μsec/hit.";
-```
-
-**21.** No escriba varias expresiones en una sola línea.
-
-**22.** Agrupe secciones de código dentro de las funciones y sepárelas con no más de una línea vacía.
-
-**23.** Separe funciones, clases, etc. con una o dos líneas vacías.
-
-**24.** `A const` (relacionado con un valor) debe escribirse antes del nombre del tipo.
-
-``` cpp
-//correct
-const char * pos
-const std::string & s
-//incorrect
-char const * pos
-```
-
-**25.** Al declarar un puntero o referencia, el `*` y `&` Los símbolos deben estar separados por espacios en ambos lados.
-
-``` cpp
-//correct
-const char * pos
-//incorrect
-const char* pos
-const char *pos
-```
-
-**26.** Cuando utilice tipos de plantilla, alias con el `using` palabra clave (excepto en los casos más simples).
-
-En otras palabras, los parámetros de la plantilla se especifican solo en `using` y no se repiten en el código.
-
-`using` se puede declarar localmente, como dentro de una función.
-
-``` cpp
-//correct
-using FileStreams = std::map<std::string, std::shared_ptr<Stream>>;
-FileStreams streams;
-//incorrect
-std::map<std::string, std::shared_ptr<Stream>> streams;
-```
-
-**27.** No declare varias variables de diferentes tipos en una instrucción.
-
-``` cpp
-//incorrect
-int x, *y;
-```
-
-**28.** No utilice moldes de estilo C.
-
-``` cpp
-//incorrect
-std::cerr << (int)c <<; std::endl;
-//correct
-std::cerr << static_cast<int>(c) << std::endl;
-```
-
-**29.** En clases y estructuras, los miembros del grupo y las funciones por separado dentro de cada ámbito de visibilidad.
-
-**30.** Para clases y estructuras pequeñas, no es necesario separar la declaración del método de la implementación.
-
-Lo mismo es cierto para los métodos pequeños en cualquier clase o estructura.
-
-Para clases y estructuras con plantillas, no separe las declaraciones de métodos de la implementación (porque de lo contrario deben definirse en la misma unidad de traducción).
-
-**31.** Puede ajustar líneas en 140 caracteres, en lugar de 80.
-
-**32.** Utilice siempre los operadores de incremento / decremento de prefijo si no se requiere postfix.
-
-``` cpp
-for (Names::const_iterator it = column_names.begin(); it != column_names.end(); ++it)
-```
-
-## Comentario {#comments}
-
-**1.** Asegúrese de agregar comentarios para todas las partes no triviales del código.
-
-Esto es muy importante. Escribir el comentario puede ayudarte a darte cuenta de que el código no es necesario o que está diseñado incorrectamente.
-
-``` cpp
-/** Part of piece of memory, that can be used.
-  * For example, if internal_buffer is 1MB, and there was only 10 bytes loaded to buffer from file for reading,
-  * then working_buffer will have size of only 10 bytes
-  * (working_buffer.end() will point to position right after those 10 bytes available for read).
-  */
-```
-
-**2.** Los comentarios pueden ser tan detallados como sea necesario.
-
-**3.** Coloque comentarios antes del código que describen. En casos raros, los comentarios pueden aparecer después del código, en la misma línea.
-
-``` cpp
-/** Parses and executes the query.
-*/
-void executeQuery(
-    ReadBuffer & istr, /// Where to read the query from (and data for INSERT, if applicable)
-    WriteBuffer & ostr, /// Where to write the result
-    Context & context, /// DB, tables, data types, engines, functions, aggregate functions...
-    BlockInputStreamPtr & query_plan, /// Here could be written the description on how query was executed
-    QueryProcessingStage::Enum stage = QueryProcessingStage::Complete /// Up to which stage process the SELECT query
-    )
-```
-
-**4.** Los comentarios deben escribirse en inglés solamente.
-
-**5.** Si está escribiendo una biblioteca, incluya comentarios detallados que la expliquen en el archivo de encabezado principal.
-
-**6.** No agregue comentarios que no proporcionen información adicional. En particular, no deje comentarios vacíos como este:
-
-``` cpp

-```
-
-El ejemplo se toma prestado del recurso http://home.tamk.fi/~jaalto/course/coding-style/doc/unmaintainable-code/.
-
-**7.** No escriba comentarios de basura (autor, fecha de creación ..) al principio de cada archivo.
-
-**8.** Los comentarios de una sola línea comienzan con tres barras: `///` y los comentarios de varias líneas comienzan con `/**`. Estos comentarios son considerados “documentation”.
-
-Nota: Puede usar Doxygen para generar documentación a partir de estos comentarios. Pero Doxygen no se usa generalmente porque es más conveniente navegar por el código en el IDE.
-
-**9.** Los comentarios de varias líneas no deben tener líneas vacías al principio y al final (excepto la línea que cierra un comentario de varias líneas).
-
-**10.** Para comentar el código, use comentarios básicos, no “documenting” comentario.
-
-**11.** Elimine las partes comentadas del código antes de confirmar.
-
-**12.** No use blasfemias en comentarios o código.
-
-**13.** No use letras mayúsculas. No use puntuación excesiva.
-
-``` cpp
-/// WHAT THE FAIL???
-```
-
-**14.** No use comentarios para hacer delímetros.
-
-``` cpp
-///******************************************************
-```
-
-**15.** No comiencen las discusiones en los comentarios.
-
-``` cpp
-/// Why did you do this stuff?
-```
-
-**16.** No es necesario escribir un comentario al final de un bloque que describa de qué se trataba.
-
-``` cpp
-/// for
-```
-
-## Nombre {#names}
-
-**1.** Use letras minúsculas con guiones bajos en los nombres de variables y miembros de clase.
-
-``` cpp
-size_t max_block_size;
-```
-
-**2.** Para los nombres de las funciones (métodos), use camelCase comenzando con una letra minúscula.
-
-``` cpp
-std::string getName() const override { return "Memory"; }
-```
-
-**3.** Para los nombres de las clases (estructuras), use CamelCase comenzando con una letra mayúscula. Los prefijos distintos de I no se usan para interfaces.
-
-``` cpp
-class StorageMemory : public IStorage
-```
-
-**4.** `using` se nombran de la misma manera que las clases, o con `_t` al final.
-
-**5.** Nombres de argumentos de tipo de plantilla: en casos simples, use `T`; `T`, `U`; `T1`, `T2`.
-
-Para casos más complejos, siga las reglas para los nombres de clase o agregue el prefijo `T`.
-
-``` cpp
-template <typename TKey, typename TValue>
-struct AggregatedStatElement
-```
-
-**6.** Nombres de argumentos constantes de plantilla: siga las reglas para los nombres de variables o use `N` en casos simples.
-
-``` cpp
-template <bool without_www>
-struct ExtractDomain
-```
-
-**7.** Para clases abstractas (interfaces) puede agregar el `I` prefijo.
-
-``` cpp
-class IBlockInputStream
-```
-
-**8.** Si usa una variable localmente, puede usar el nombre corto.
-
-En todos los demás casos, use un nombre que describa el significado.
-
-``` cpp
-bool info_successfully_loaded = false;
-```
-
-**9.** Nombres de `define`s y las constantes globales usan ALL_CAPS con guiones bajos.
-
-``` cpp
-#define MAX_SRC_TABLE_NAMES_TO_STORE 1000
-```
-
-**10.** Los nombres de archivo deben usar el mismo estilo que su contenido.
-
-Si un archivo contiene una sola clase, nombre el archivo de la misma manera que la clase (CamelCase).
-
-Si el archivo contiene una sola función, nombre el archivo de la misma manera que la función (camelCase).
-
-**11.** Si el nombre contiene una abreviatura, :
-
--   Para los nombres de variables, la abreviatura debe usar letras minúsculas `mysql_connection` (ni `mySQL_connection`).
--   Para los nombres de clases y funciones, mantenga las letras mayúsculas en la abreviatura`MySQLConnection` (ni `MySqlConnection`).
-
-**12.** Los argumentos del constructor que se usan solo para inicializar los miembros de la clase deben nombrarse de la misma manera que los miembros de la clase, pero con un guión bajo al final.
-
-``` cpp
-FileQueueProcessor(
-    const std::string & path_,
-    const std::string & prefix_,
-    std::shared_ptr<FileHandler> handler_)
-    : path(path_),
-    prefix(prefix_),
-    handler(handler_),
-    log(&Logger::get("FileQueueProcessor"))
-{
-}
-```
-
-El sufijo de subrayado se puede omitir si el argumento no se usa en el cuerpo del constructor.
-
-**13.** No hay diferencia en los nombres de las variables locales y los miembros de la clase (no se requieren prefijos).
-
-``` cpp
-timer (not m_timer)
-```
-
-**14.** Para las constantes en un `enum`, usar CamelCase con una letra mayúscula. ALL_CAPS también es aceptable. Si el `enum` no es local, utilice un `enum class`.
-
-``` cpp
-enum class CompressionMethod
-{
-    QuickLZ = 0,
-    LZ4     = 1,
-};
-```
-
-**15.** Todos los nombres deben estar en inglés. La transliteración de palabras rusas no está permitida.
-
-    not Stroka
-
-**16.** Las abreviaturas son aceptables si son bien conocidas (cuando puede encontrar fácilmente el significado de la abreviatura en Wikipedia o en un motor de búsqueda).
-
-    `AST`, `SQL`.
-
-    Not `NVDH` (some random letters)
-
-Las palabras incompletas son aceptables si la versión abreviada es de uso común.
-
-También puede usar una abreviatura si el nombre completo se incluye junto a él en los comentarios.
-
-**17.** Los nombres de archivo con código fuente de C++ deben tener `.cpp` ampliación. Los archivos de encabezado deben tener `.h` ampliación.
-
-## Cómo escribir código {#how-to-write-code}
-
-**1.** Gestión de la memoria.
-
-Desasignación de memoria manual (`delete`) solo se puede usar en el código de la biblioteca.
-
-En el código de la biblioteca, el `delete` operador sólo se puede utilizar en destructores.
-
-En el código de la aplicación, la memoria debe ser liberada por el objeto que la posee.
-
-Ejemplos:
-
--   La forma más fácil es colocar un objeto en la pila o convertirlo en miembro de otra clase.
--   Para una gran cantidad de objetos pequeños, use contenedores.
--   Para la desasignación automática de un pequeño número de objetos que residen en el montón, use `shared_ptr/unique_ptr`.
-
-**2.** Gestión de recursos.
-
-Utilizar `RAII` y ver arriba.
-
-**3.** Manejo de errores.
-
-Utilice excepciones. En la mayoría de los casos, solo necesita lanzar una excepción y no necesita atraparla (debido a `RAII`).
-
-En las aplicaciones de procesamiento de datos fuera de línea, a menudo es aceptable no detectar excepciones.
-
-En los servidores que manejan las solicitudes de los usuarios, generalmente es suficiente detectar excepciones en el nivel superior del controlador de conexión.
-
-En las funciones de subproceso, debe capturar y mantener todas las excepciones para volver a lanzarlas en el subproceso principal después `join`.
-
-``` cpp
-/// If there weren't any calculations yet, calculate the first block synchronously
-if (!started)
-{
-    calculate();
-    started = true;
-}
-else /// If calculations are already in progress, wait for the result
-    pool.wait();
-
-if (exception)
-    exception->rethrow();
-```
-
-Nunca oculte excepciones sin manejo. Nunca simplemente ponga ciegamente todas las excepciones para iniciar sesión.
-
-``` cpp
-//Not correct
-catch (...) {}
-```
-
-Si necesita ignorar algunas excepciones, hágalo solo para las específicas y vuelva a lanzar el resto.
-
-``` cpp
-catch (const DB::Exception & e)
-{
-    if (e.code() == ErrorCodes::UNKNOWN_AGGREGATE_FUNCTION)
-        return nullptr;
-    else
-        throw;
-}
-```
-
-Al usar funciones con códigos de respuesta o `errno`, siempre verifique el resultado y arroje una excepción en caso de error.
-
-``` cpp
-if (0 != close(fd))
-    throwFromErrno("Cannot close file " + file_name, ErrorCodes::CANNOT_CLOSE_FILE);
-```
-
-`Do not use assert`.
-
-**4.** Tipos de excepción.
-
-No es necesario utilizar una jerarquía de excepciones compleja en el código de la aplicación. El texto de excepción debe ser comprensible para un administrador del sistema.
-
-**5.** Lanzar excepciones de destructores.
-
-Esto no es recomendable, pero está permitido.
-
-Utilice las siguientes opciones:
-
--   Crear una función (`done()` o `finalize()`) que hará todo el trabajo de antemano que podría conducir a una excepción. Si se llamó a esa función, no debería haber excepciones en el destructor más adelante.
--   Las tareas que son demasiado complejas (como enviar mensajes a través de la red) se pueden poner en un método separado al que el usuario de la clase tendrá que llamar antes de la destrucción.
--   Si hay una excepción en el destructor, es mejor registrarla que ocultarla (si el registrador está disponible).
--   En aplicaciones simples, es aceptable confiar en `std::terminate` (para los casos de `noexcept` de forma predeterminada en C ++ 11) para manejar excepciones.
-
-**6.** Bloques de código anónimos.
-
-Puede crear un bloque de código separado dentro de una sola función para hacer que ciertas variables sean locales, de modo que se llame a los destructores al salir del bloque.
-
-``` cpp
-Block block = data.in->read();
-
-{
-    std::lock_guard<std::mutex> lock(mutex);
-    data.ready = true;
-    data.block = block;
-}
-
-ready_any.set();
-```
-
-**7.** Multithreading.
-
-En programas de procesamiento de datos fuera de línea:
-
--   Trate de obtener el mejor rendimiento posible en un solo núcleo de CPU. A continuación, puede paralelizar su código si es necesario.
-
-En aplicaciones de servidor:
-
--   Utilice el grupo de subprocesos para procesar solicitudes. En este punto, no hemos tenido ninguna tarea que requiera el cambio de contexto de espacio de usuario.
-
-La horquilla no se usa para la paralelización.
-
-**8.** Sincronización de hilos.
-
-A menudo es posible hacer que diferentes hilos usen diferentes celdas de memoria (incluso mejor: diferentes líneas de caché) y no usar ninguna sincronización de hilos (excepto `joinAll`).
-
-Si se requiere sincronización, en la mayoría de los casos, es suficiente usar mutex bajo `lock_guard`.
-
-En otros casos, use primitivas de sincronización del sistema. No utilice la espera ocupada.
-
-Las operaciones atómicas deben usarse solo en los casos más simples.
-
-No intente implementar estructuras de datos sin bloqueo a menos que sea su principal área de especialización.
-
-**9.** Punteros vs referencias.
-
-En la mayoría de los casos, prefiera referencias.
-
-**10.** Construir.
-
-Usar referencias constantes, punteros a constantes, `const_iterator`, y métodos const.
-
-Considerar `const` para ser predeterminado y usar no-`const` sólo cuando sea necesario.
-
-Al pasar variables por valor, usando `const` por lo general no tiene sentido.
-
-**11.** sin firmar.
-
-Utilizar `unsigned` si es necesario.
-
-**12.** Tipos numéricos.
-
-Utilice los tipos `UInt8`, `UInt16`, `UInt32`, `UInt64`, `Int8`, `Int16`, `Int32`, y `Int64`, así como `size_t`, `ssize_t`, y `ptrdiff_t`.
-
-No use estos tipos para números: `signed/unsigned long`, `long long`, `short`, `signed/unsigned char`, `char`.
-
-**13.** Pasando argumentos.
-
-Pasar valores complejos por referencia (incluyendo `std::string`).
-
-Si una función captura la propiedad de un objeto creado en el montón, cree el tipo de argumento `shared_ptr` o `unique_ptr`.
-
-**14.** Valores devueltos.
-
-En la mayoría de los casos, sólo tiene que utilizar `return`. No escribir `return std::move(res)`.
-
-Si la función asigna un objeto en el montón y lo devuelve, use `shared_ptr` o `unique_ptr`.
-
-En casos excepcionales, es posible que deba devolver el valor a través de un argumento. En este caso, el argumento debe ser una referencia.
-
-``` cpp
-using AggregateFunctionPtr = std::shared_ptr<IAggregateFunction>;
-
-/** Allows creating an aggregate function by its name.
-  */
-class AggregateFunctionFactory
-{
-public:
-    AggregateFunctionFactory();
-    AggregateFunctionPtr get(const String & name, const DataTypes & argument_types) const;
-```
-
-**15.** espacio de nombres.
-
-No hay necesidad de usar un `namespace` para el código de aplicación.
-
-Las bibliotecas pequeñas tampoco necesitan esto.
-
-Para bibliotecas medianas a grandes, coloque todo en un `namespace`.
-
-En la biblioteca `.h` archivo, se puede utilizar `namespace detail` para ocultar los detalles de implementación no necesarios para el código de la aplicación.
-
-En un `.cpp` archivo, puede usar un `static` o espacio de nombres anónimo para ocultar símbolos.
-
-Además, un `namespace` puede ser utilizado para un `enum` para evitar que los nombres correspondientes caigan en un `namespace` (pero es mejor usar un `enum class`).
-
-**16.** Inicialización diferida.
-
-Si se requieren argumentos para la inicialización, normalmente no debe escribir un constructor predeterminado.
-
-Si más adelante tendrá que retrasar la inicialización, puede agregar un constructor predeterminado que creará un objeto no válido. O, para un pequeño número de objetos, puede usar `shared_ptr/unique_ptr`.
-
-``` cpp
-Loader(DB::Connection * connection_, const std::string & query, size_t max_block_size_);
-
-/// For deferred initialization
-Loader() {}
-```
-
-**17.** Funciones virtuales.
-
-Si la clase no está destinada para uso polimórfico, no necesita hacer que las funciones sean virtuales. Esto también se aplica al destructor.
-
-**18.** Codificación.
-
-Usa UTF-8 en todas partes. Utilizar `std::string`y`char *`. No use `std::wstring`y`wchar_t`.
-
-**19.** Tala.
-
-Vea los ejemplos en todas partes del código.
-
-Antes de confirmar, elimine todo el registro de depuración y sin sentido, y cualquier otro tipo de salida de depuración.
-
-Se debe evitar el registro en ciclos, incluso en el nivel Trace.
-
-Los registros deben ser legibles en cualquier nivel de registro.
-
-El registro solo debe usarse en el código de la aplicación, en su mayor parte.
-
-Los mensajes de registro deben estar escritos en inglés.
-
-El registro debe ser preferiblemente comprensible para el administrador del sistema.
-
-No use blasfemias en el registro.
-
-Utilice la codificación UTF-8 en el registro. En casos excepcionales, puede usar caracteres que no sean ASCII en el registro.
-
-**20.** Entrada-salida.
-
-No utilice `iostreams` en ciclos internos que son críticos para el rendimiento de la aplicación (y nunca usan `stringstream`).
-
-Utilice el `DB/IO` biblioteca en su lugar.
-
-**21.** Fecha y hora.
-
-Ver el `DateLUT` biblioteca.
-
-**22.** incluir.
-
-Utilice siempre `#pragma once` en lugar de incluir guardias.
-
-**23.** utilizar.
-
-`using namespace` no se utiliza. Usted puede utilizar `using` con algo específico. Pero hazlo local dentro de una clase o función.
-
-**24.** No use `trailing return type` para funciones a menos que sea necesario.
-
-``` cpp
-auto f() -> void
-```
-
-**25.** Declaración e inicialización de variables.
-
-``` cpp
-//right way
-std::string s = "Hello";
-std::string s{"Hello"};
-
-//wrong way
-auto s = std::string{"Hello"};
-```
-
-**26.** Para funciones virtuales, escriba `virtual` en la clase base, pero escribe `override` en lugar de `virtual` en las clases descendientes.
-
-## Características no utilizadas de C ++ {#unused-features-of-c}
-
-**1.** La herencia virtual no se utiliza.
-
-**2.** Los especificadores de excepción de C ++ 03 no se usan.
-
-## Plataforma {#platform}
-
-**1.** Escribimos código para una plataforma específica.
-
-Pero en igualdad de condiciones, se prefiere el código multiplataforma o portátil.
-
-**2.** Idioma: C++20.
-
-**3.** Compilación: `gcc`. En este momento (agosto 2020), el código se compila utilizando la versión 9.3. (También se puede compilar usando `clang 8`.)
-
-Se utiliza la biblioteca estándar (`libc++`).
-
-**4.**OS: Linux Ubuntu, no más viejo que Precise.
-
-**5.**El código está escrito para la arquitectura de CPU x86_64.
-
-El conjunto de instrucciones de CPU es el conjunto mínimo admitido entre nuestros servidores. Actualmente, es SSE 4.2.
-
-**6.** Utilizar `-Wall -Wextra -Werror` flags de compilación.
-
-**7.** Use enlaces estáticos con todas las bibliotecas, excepto aquellas a las que son difíciles de conectar estáticamente (consulte la salida de la `ldd` comando).
-
-**8.** El código se desarrolla y se depura con la configuración de la versión.
-
-## Herramienta {#tools}
-
-**1.** KDevelop es un buen IDE.
-
-**2.** Para la depuración, use `gdb`, `valgrind` (`memcheck`), `strace`, `-fsanitize=...`, o `tcmalloc_minimal_debug`.
-
-**3.** Para crear perfiles, use `Linux Perf`, `valgrind` (`callgrind`), o `strace -cf`.
-
-**4.** Las fuentes están en Git.
-
-**5.** Usos de ensamblaje `CMake`.
-
-**6.** Los programas se lanzan usando `deb` paquete.
-
-**7.** Los compromisos a dominar no deben romper la compilación.
-
-Aunque solo las revisiones seleccionadas se consideran viables.
-
-**8.** Realice confirmaciones tan a menudo como sea posible, incluso si el código está parcialmente listo.
-
-Use ramas para este propósito.
-
-Si su código en el `master` branch todavía no se puede construir, excluirlo de la compilación antes de la `push`. Tendrá que terminarlo o eliminarlo dentro de unos días.
-
-**9.** Para cambios no triviales, use ramas y publíquelas en el servidor.
-
-**10.** El código no utilizado se elimina del repositorio.
-
-## Biblioteca {#libraries}
-
-**1.** Se utiliza la biblioteca estándar de C++20 (se permiten extensiones experimentales), así como `boost` y `Poco` marco.
-
-**2.** Si es necesario, puede usar cualquier biblioteca conocida disponible en el paquete del sistema operativo.
-
-Si ya hay una buena solución disponible, úsela, incluso si eso significa que debe instalar otra biblioteca.
-
-(Pero prepárese para eliminar las bibliotecas incorrectas del código.)
-
-**3.** Puede instalar una biblioteca que no esté en los paquetes, si los paquetes no tienen lo que necesita o tienen una versión obsoleta o el tipo de compilación incorrecto.
-
-**4.** Si la biblioteca es pequeña y no tiene su propio sistema de compilación complejo, coloque los archivos `contrib` carpeta.
-
-**5.** Siempre se da preferencia a las bibliotecas que ya están en uso.
-
-## Recomendaciones generales {#general-recommendations-1}
-
-**1.** Escribe el menor código posible.
-
-**2.** Pruebe la solución más simple.
-
-**3.** No escriba código hasta que sepa cómo va a funcionar y cómo funcionará el bucle interno.
-
-**4.** En los casos más simples, use `using` en lugar de clases o estructuras.
-
-**5.** Si es posible, no escriba constructores de copia, operadores de asignación, destructores (que no sean virtuales, si la clase contiene al menos una función virtual), mueva constructores o mueva operadores de asignación. En otras palabras, las funciones generadas por el compilador deben funcionar correctamente. Usted puede utilizar `default`.
-
-**6.** Se fomenta la simplificación del código. Reduzca el tamaño de su código siempre que sea posible.
-
-## Recomendaciones adicionales {#additional-recommendations}
-
-**1.** Especificar explícitamente `std::` para tipos de `stddef.h`
-
-no se recomienda. En otras palabras, recomendamos escribir `size_t` en su lugar `std::size_t` porque es más corto.
-
-Es aceptable agregar `std::`.
-
-**2.** Especificar explícitamente `std::` para funciones de la biblioteca C estándar
-
-no se recomienda. En otras palabras, escribir `memcpy` en lugar de `std::memcpy`.
-
-La razón es que hay funciones no estándar similares, tales como `memmem`. Utilizamos estas funciones en ocasiones. Estas funciones no existen en `namespace std`.
-
-Si usted escribe `std::memcpy` en lugar de `memcpy` en todas partes, entonces `memmem` sin `std::` se verá extraño.
-
-Sin embargo, todavía puedes usar `std::` si lo prefieres.
-
-**3.** Usar funciones de C cuando las mismas están disponibles en la biblioteca estándar de C ++.
-
-Esto es aceptable si es más eficiente.
-
-Por ejemplo, use `memcpy` en lugar de `std::copy` para copiar grandes trozos de memoria.
-
-**4.** Argumentos de función multilínea.
-
-Se permite cualquiera de los siguientes estilos de ajuste:
-
-``` cpp
-function(
-  T1 x1,
-  T2 x2)
-```
-
-``` cpp
-function(
-  size_t left, size_t right,
-  const & RangesInDataParts ranges,
-  size_t limit)
-```
-
-``` cpp
-function(size_t left, size_t right,
-  const & RangesInDataParts ranges,
-  size_t limit)
-```
-
-``` cpp
-function(size_t left, size_t right,
-      const & RangesInDataParts ranges,
-      size_t limit)
-```
-
-``` cpp
-function(
-      size_t left,
-      size_t right,
-      const & RangesInDataParts ranges,
-      size_t limit)
-```

-# Motores de mesa {#table_engines}
-
-El motor de tabla (tipo de tabla) determina:
-
--   Cómo y dónde se almacenan los datos, dónde escribirlos y dónde leerlos.
--   Qué consultas son compatibles y cómo.
--   Acceso a datos simultáneos.
--   Uso de índices, si está presente.
--   Si es posible la ejecución de solicitudes multiproceso.
--   Parámetros de replicación de datos.
-
-## Familias de motores {#engine-families}
-
-### Método de codificación de datos: {#mergetree}
-
-Los motores de mesa más universales y funcionales para tareas de alta carga. La propiedad compartida por estos motores es la inserción rápida de datos con el posterior procesamiento de datos en segundo plano. `MergeTree` Los motores familiares admiten la replicación de datos (con [Replicado\*](mergetree-family/replication.md#table_engines-replication) versiones de motores), particionamiento y otras características no admitidas en otros motores.

-## Virtual Columnas {#table_engines-virtual_columns}
-
-La columna virtual es un atributo de motor de tabla integral que se define en el código fuente del motor.
-
-No debe especificar columnas virtuales en el `CREATE TABLE` consulta y no puedes verlos en `SHOW CREATE TABLE` y `DESCRIBE TABLE` resultados de la consulta. Las columnas virtuales también son de solo lectura, por lo que no puede insertar datos en columnas virtuales.
-
-Para seleccionar datos de una columna virtual, debe especificar su nombre en el `SELECT` consulta. `SELECT *` no devuelve valores de columnas virtuales.
-
-Si crea una tabla con una columna que tiene el mismo nombre que una de las columnas virtuales de la tabla, la columna virtual se vuelve inaccesible. No recomendamos hacer esto. Para ayudar a evitar conflictos, los nombres de columna virtual suelen tener el prefijo de un guión bajo.

-# HDFS {#table_engines-hdfs}
-
-Este motor proporciona integración con [Acerca de nosotros](https://en.wikipedia.org/wiki/Apache_Hadoop) permitiendo gestionar datos sobre [HDFS](https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html)a través de ClickHouse. Este motor es similar
-a la [File](../special/file.md#table_engines-file) y [URL](../special/url.md#table_engines-url) motores, pero proporciona características específicas de Hadoop.
-
-## Uso {#usage}
-
-``` sql
-ENGINE = HDFS(URI, format)
-```
-
-El `URI` El parámetro es el URI del archivo completo en HDFS.
-El `format` parámetro especifica uno de los formatos de archivo disponibles. Realizar
-`SELECT` consultas, el formato debe ser compatible para la entrada, y para realizar
-`INSERT` queries – for output. The available formats are listed in the
-[Formato](../../../interfaces/formats.md#formats) apartado.
-La parte de la ruta de `URI` puede contener globs. En este caso, la tabla sería de solo lectura.
-
-**Ejemplo:**
-
-**1.** Configurar el `hdfs_engine_table` tabla:
-
-``` sql
-CREATE TABLE hdfs_engine_table (name String, value UInt32) ENGINE=HDFS('hdfs://hdfs1:9000/other_storage', 'TSV')
-```
-
-**2.** Llenar archivo:
-
-``` sql
-INSERT INTO hdfs_engine_table VALUES ('one', 1), ('two', 2), ('three', 3)
-```
-
-**3.** Consultar los datos:
-
-``` sql
-SELECT * FROM hdfs_engine_table LIMIT 2
-```
-
-``` text
-┌─name─┬─value─┐
-│ one  │     1 │
-│ two  │     2 │
-└──────┴───────┘
-```
-
-## Detalles de implementación {#implementation-details}
-
--   Las lecturas y escrituras pueden ser paralelas
--   No soportado:
-    -   `ALTER` y `SELECT...SAMPLE` operación.
-    -   Índices.
-    -   Replicación.
-
-**Globs en el camino**
-
-Múltiples componentes de ruta de acceso pueden tener globs. Para ser procesado, el archivo debe existir y coincidir con todo el patrón de ruta. Listado de archivos determina durante `SELECT` (no en `CREATE` momento).
-
--   `*` — Substitutes any number of any characters except `/` incluyendo cadena vacía.
--   `?` — Substitutes any single character.
--   `{some_string,another_string,yet_another_one}` — Substitutes any of strings `'some_string', 'another_string', 'yet_another_one'`.
--   `{N..M}` — Substitutes any number in range from N to M including both borders.
-
-Construcciones con `{}` son similares a la [remoto](../../../sql-reference/table-functions/remote.md) función de la tabla.
-
-**Ejemplo**
-
-1.  Supongamos que tenemos varios archivos en formato TSV con los siguientes URI en HDFS:
-
--   ‘hdfs://hdfs1:9000/some_dir/some_file_1’
--   ‘hdfs://hdfs1:9000/some_dir/some_file_2’
--   ‘hdfs://hdfs1:9000/some_dir/some_file_3’
--   ‘hdfs://hdfs1:9000/another_dir/some_file_1’
--   ‘hdfs://hdfs1:9000/another_dir/some_file_2’
--   ‘hdfs://hdfs1:9000/another_dir/some_file_3’
-
-1.  Hay varias maneras de hacer una tabla que consta de los seis archivos:
-
-<!-- -->
-
-``` sql
-CREATE TABLE table_with_range (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/{some,another}_dir/some_file_{1..3}', 'TSV')
-```
-
-Otra forma:
-
-``` sql
-CREATE TABLE table_with_question_mark (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/{some,another}_dir/some_file_?', 'TSV')
-```
-
-La tabla consta de todos los archivos en ambos directorios (todos los archivos deben satisfacer el formato y el esquema descritos en la consulta):
-
-``` sql
-CREATE TABLE table_with_asterisk (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/{some,another}_dir/*', 'TSV')
-```
-
-!!! warning "Advertencia"
-    Si la lista de archivos contiene rangos de números con ceros a la izquierda, use la construcción con llaves para cada dígito por separado o use `?`.
-
-**Ejemplo**
-
-Crear tabla con archivos llamados `file000`, `file001`, … , `file999`:
-
-``` sql
-CREARE TABLE big_table (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/big_dir/file{0..9}{0..9}{0..9}', 'CSV')
-```
-
-## Virtual Columnas {#virtual-columns}
-
--   `_path` — Path to the file.
--   `_file` — Name of the file.

-# JDBC {#table-engine-jdbc}
-
-Permite que ClickHouse se conecte a bases de datos externas a través de [JDBC](https://en.wikipedia.org/wiki/Java_Database_Connectivity).
-
-Para implementar la conexión JDBC, ClickHouse utiliza el programa independiente [Sistema abierto.](https://github.com/alex-krash/clickhouse-jdbc-bridge) que debería ejecutarse como un demonio.
-
-Este motor soporta el [NULL](../../../sql-reference/data-types/nullable.md) tipo de datos.
-
-## Creación de una tabla {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name
-(
-    columns list...
-)
-ENGINE = JDBC(dbms_uri, external_database, external_table)
-```
-
-**Parámetros del motor**
-
--   `dbms_uri` — URI of an external DBMS.
-
-    Formato: `jdbc:<driver_name>://<host_name>:<port>/?user=<username>&password=<password>`.
-    Ejemplo para MySQL: `jdbc:mysql://localhost:3306/?user=root&password=root`.
-
--   `external_database` — Database in an external DBMS.
-
--   `external_table` — Name of the table in `external_database`.
-
-## Ejemplo de uso {#usage-example}
-
-Crear una tabla en el servidor MySQL conectándose directamente con su cliente de consola:
-
-``` text
-mysql> CREATE TABLE `test`.`test` (
-    ->   `int_id` INT NOT NULL AUTO_INCREMENT,
-    ->   `int_nullable` INT NULL DEFAULT NULL,
-    ->   `float` FLOAT NOT NULL,
-    ->   `float_nullable` FLOAT NULL DEFAULT NULL,
-    ->   PRIMARY KEY (`int_id`));
-Query OK, 0 rows affected (0,09 sec)
-
-mysql> insert into test (`int_id`, `float`) VALUES (1,2);
-Query OK, 1 row affected (0,00 sec)
-
-mysql> select * from test;
-+------+----------+-----+----------+
-| int_id | int_nullable | float | float_nullable |
-+------+----------+-----+----------+
-|      1 |         NULL |     2 |           NULL |
-+------+----------+-----+----------+
-1 row in set (0,00 sec)
-```
-
-Creación de una tabla en el servidor ClickHouse y selección de datos de ella:
-
-``` sql
-CREATE TABLE jdbc_table
-(
-    `int_id` Int32,
-    `int_nullable` Nullable(Int32),

-
--   Publicar o suscribirse a flujos de datos.
--   Organice el almacenamiento tolerante a fallos.
--   Secuencias de proceso a medida que estén disponibles.
-
-## Creación de una tabla {#table_engine-kafka-creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = Kafka()
-SETTINGS
-    kafka_broker_list = 'host:port',
-    kafka_topic_list = 'topic1,topic2,...',
-    kafka_group_name = 'group_name',
-    kafka_format = 'data_format'[,]
-    [kafka_row_delimiter = 'delimiter_symbol',]
-    [kafka_schema = '',]
-    [kafka_num_consumers = N,]
-    [kafka_max_block_size = 0,]
-    [kafka_skip_broken_messages = N,]
-    [kafka_commit_every_batch = 0]
-```
-
-Parámetros requeridos:
-
--   `kafka_broker_list` – A comma-separated list of brokers (for example, `localhost:9092`).
--   `kafka_topic_list` – A list of Kafka topics.
--   `kafka_group_name` – A group of Kafka consumers. Reading margins are tracked for each group separately. If you don't want messages to be duplicated in the cluster, use the same group name everywhere.
--   `kafka_format` – Message format. Uses the same notation as the SQL `FORMAT` función, tal como `JSONEachRow`. Para obtener más información, consulte [Formato](../../../interfaces/formats.md) apartado.
-
-Parámetros opcionales:
-
--   `kafka_row_delimiter` – Delimiter character, which ends the message.
--   `kafka_schema` – Parameter that must be used if the format requires a schema definition. For example, [Cap'n Proto](https://capnproto.org/) requiere la ruta de acceso al archivo de esquema y el nombre de la raíz `schema.capnp:Message` objeto.
--   `kafka_num_consumers` – The number of consumers per table. Default: `1`. Especifique más consumidores si el rendimiento de un consumidor es insuficiente. El número total de consumidores no debe exceder el número de particiones en el tema, ya que solo se puede asignar un consumidor por partición.
--   `kafka_max_block_size` - El tamaño máximo de lote (en mensajes) para la encuesta (predeterminado: `max_block_size`).
--   `kafka_skip_broken_messages` – Kafka message parser tolerance to schema-incompatible messages per block. Default: `0`. Si `kafka_skip_broken_messages = N` entonces el motor salta *N* Mensajes de Kafka que no se pueden analizar (un mensaje es igual a una fila de datos).
--   `kafka_commit_every_batch` - Confirmar cada lote consumido y manejado en lugar de una única confirmación después de escribir un bloque completo (predeterminado: `0`).
-
-Ejemplos:
-
-``` sql
-  CREATE TABLE queue (
-    timestamp UInt64,
-    level String,
-    message String
-  ) ENGINE = Kafka('localhost:9092', 'topic', 'group1', 'JSONEachRow');

-Los mensajes entregados se realizan un seguimiento automático, por lo que cada mensaje de un grupo solo se cuenta una vez. Si desea obtener los datos dos veces, cree una copia de la tabla con otro nombre de grupo.
-
-Los grupos son flexibles y se sincronizan en el clúster. Por ejemplo, si tiene 10 temas y 5 copias de una tabla en un clúster, cada copia obtiene 2 temas. Si el número de copias cambia, los temas se redistribuyen automáticamente entre las copias. Lea más sobre esto en http://kafka.apache.org/intro .
-
-`SELECT` no es particularmente útil para leer mensajes (excepto para la depuración), ya que cada mensaje se puede leer solo una vez. Es más práctico crear subprocesos en tiempo real utilizando vistas materializadas. Para hacer esto:
-
-1.  Use el motor para crear un consumidor de Kafka y considérelo como un flujo de datos.
-2.  Crea una tabla con la estructura deseada.
-3.  Cree una vista materializada que convierta los datos del motor y los coloque en una tabla creada previamente.
-
-Cuando el `MATERIALIZED VIEW` se une al motor, comienza a recopilar datos en segundo plano. Esto le permite recibir continuamente mensajes de Kafka y convertirlos al formato requerido usando `SELECT`.
-Una tabla kafka puede tener tantas vistas materializadas como desee, no leen datos de la tabla kafka directamente, sino que reciben nuevos registros (en bloques), de esta manera puede escribir en varias tablas con diferentes niveles de detalle (con agrupación - agregación y sin).
-
-Ejemplo:
-
-``` sql
-  CREATE TABLE queue (
-    timestamp UInt64,
-    level String,
-    message String
-  ) ENGINE = Kafka('localhost:9092', 'topic', 'group1', 'JSONEachRow');
-
-  CREATE TABLE daily (
-    day Date,
-    level String,
-    total UInt64
-  ) ENGINE = SummingMergeTree(day, (day, level), 8192);
-
-  CREATE MATERIALIZED VIEW consumer TO daily
-    AS SELECT toDate(toDateTime(timestamp)) AS day, level, count() as total
-    FROM queue GROUP BY day, level;
-
-  SELECT level, sum(total) FROM daily GROUP BY level;
-```
-
-Para mejorar el rendimiento, los mensajes recibidos se agrupan en bloques del tamaño de [Max_insert_block_size](../../../operations/server-configuration-parameters/settings.md#settings-max_insert_block_size). Si el bloque no se formó dentro de [Nombre de la red inalámbrica (SSID):](../../../operations/server-configuration-parameters/settings.md) milisegundos, los datos se vaciarán a la tabla independientemente de la integridad del bloque.
-
-Para detener la recepción de datos de tema o cambiar la lógica de conversión, desconecte la vista materializada:
-
-``` sql
-  DETACH TABLE consumer;
-  ATTACH TABLE consumer;
-```
-
-Si desea cambiar la tabla de destino utilizando `ALTER`, recomendamos deshabilitar la vista de material para evitar discrepancias entre la tabla de destino y los datos de la vista.
-
-## Configuración {#configuration}
-
-Similar a GraphiteMergeTree, el motor Kafka admite una configuración extendida utilizando el archivo de configuración ClickHouse. Hay dos claves de configuración que puede usar: global (`kafka`) y a nivel de tema (`kafka_*`). La configuración global se aplica primero y, a continuación, se aplica la configuración de nivel de tema (si existe).
-
-``` xml
-  <!-- Global configuration options for all tables of Kafka engine type -->
-  <kafka>
-    <debug>cgrp</debug>
-    <auto_offset_reset>smallest</auto_offset_reset>
-  </kafka>
-
-  <!-- Configuration specific for topic "logs" -->
-  <kafka_logs>
-    <retry_backoff_ms>250</retry_backoff_ms>
-    <fetch_min_bytes>100000</fetch_min_bytes>
-  </kafka_logs>
-```
-
-Para obtener una lista de posibles opciones de configuración, consulte [referencia de configuración librdkafka](https://github.com/edenhill/librdkafka/blob/master/CONFIGURATION.md). Usa el guión bajo (`_`) en lugar de un punto en la configuración de ClickHouse. Por ejemplo, `check.crcs=true` será `<check_crcs>true</check_crcs>`.
-
-## Virtual Columnas {#virtual-columns}
-
--   `_topic` — Kafka topic.
--   `_key` — Key of the message.
--   `_offset` — Offset of the message.
--   `_timestamp` — Timestamp of the message.
--   `_partition` — Partition of Kafka topic.

-# Mysql {#mysql}
-
-El motor MySQL le permite realizar `SELECT` consultas sobre datos almacenados en un servidor MySQL remoto.
-
-## Creación de una tabla {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
-    ...
-) ENGINE = MySQL('host:port', 'database', 'table', 'user', 'password'[, replace_query, 'on_duplicate_clause']);
-```
-
-Vea una descripción detallada del [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) consulta.
-
-La estructura de la tabla puede diferir de la estructura de la tabla MySQL original:
-
--   Los nombres de columna deben ser los mismos que en la tabla MySQL original, pero puede usar solo algunas de estas columnas y en cualquier orden.
--   Los tipos de columna pueden diferir de los de la tabla MySQL original. ClickHouse intenta [elenco](../../../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) valores a los tipos de datos ClickHouse.
-
-**Parámetros del motor**
-
--   `host:port` — MySQL server address.
-
--   `database` — Remote database name.
-
--   `table` — Remote table name.
-
--   `user` — MySQL user.
-
--   `password` — User password.
-
--   `replace_query` — Flag that converts `INSERT INTO` consultas a `REPLACE INTO`. Si `replace_query=1`, la consulta se sustituye.
-
--   `on_duplicate_clause` — The `ON DUPLICATE KEY on_duplicate_clause` expresión que se añade a la `INSERT` consulta.
-
-    Ejemplo: `INSERT INTO t (c1,c2) VALUES ('a', 2) ON DUPLICATE KEY UPDATE c2 = c2 + 1`, donde `on_duplicate_clause` ser `UPDATE c2 = c2 + 1`. Ver el [Documentación de MySQL](https://dev.mysql.com/doc/refman/8.0/en/insert-on-duplicate.html) para encontrar qué `on_duplicate_clause` se puede utilizar con el `ON DUPLICATE KEY` clausula.
-
-    Especificar `on_duplicate_clause` tienes que pasar `0` a la `replace_query` parámetro. Si pasa simultáneamente `replace_query = 1` y `on_duplicate_clause`, ClickHouse genera una excepción.
-
-Simple `WHERE` cláusulas tales como `=, !=, >, >=, <, <=` se ejecutan en el servidor MySQL.
-
-El resto de las condiciones y el `LIMIT` La restricción de muestreo se ejecuta en ClickHouse solo después de que finalice la consulta a MySQL.
-

-
-Permite que ClickHouse se conecte a bases de datos externas a través de [ODBC](https://en.wikipedia.org/wiki/Open_Database_Connectivity).
-
-Para implementar con seguridad conexiones ODBC, ClickHouse usa un programa separado `clickhouse-odbc-bridge`. Si el controlador ODBC se carga directamente desde `clickhouse-server`, problemas de controlador pueden bloquear el servidor ClickHouse. ClickHouse se inicia automáticamente `clickhouse-odbc-bridge` cuando se requiere. El programa de puente ODBC se instala desde el mismo paquete que el `clickhouse-server`.

-
-**Recuperación de datos de la instalación local de MySQL a través de ODBC**
-
-Este ejemplo se comprueba para Ubuntu Linux 18.04 y el servidor MySQL 5.7.
-
-Asegúrese de que unixODBC y MySQL Connector están instalados.
-
-De forma predeterminada (si se instala desde paquetes), ClickHouse comienza como usuario `clickhouse`. Por lo tanto, debe crear y configurar este usuario en el servidor MySQL.
-
-``` bash
-$ sudo mysql
-```
-
-``` sql
-mysql> CREATE USER 'clickhouse'@'localhost' IDENTIFIED BY 'clickhouse';
-mysql> GRANT ALL PRIVILEGES ON *.* TO 'clickhouse'@'clickhouse' WITH GRANT OPTION;
-```
-
-A continuación, configure la conexión en `/etc/odbc.ini`.
-
-``` bash
-$ cat /etc/odbc.ini
-[mysqlconn]
-DRIVER = /usr/local/lib/libmyodbc5w.so
-SERVER = 127.0.0.1
-PORT = 3306
-DATABASE = test
-USERNAME = clickhouse
-PASSWORD = clickhouse
-```
-
-Puede verificar la conexión usando el `isql` utilidad desde la instalación de unixODBC.
-
-``` bash

-# Familia del motor de registro {#log-engine-family}
-
-Estos motores fueron desarrollados para escenarios en los que necesita escribir rápidamente muchas tablas pequeñas (hasta aproximadamente 1 millón de filas) y leerlas más tarde en su conjunto.
-
-Motores de la familia:
-
--   [StripeLog](stripelog.md)
--   [Registro](log.md)
--   [TinyLog](tinylog.md)
-
-## Propiedades comunes {#common-properties}
-
-Motor:
-
--   Almacenar datos en un disco.
-
--   Agregue datos al final del archivo al escribir.
-
--   Bloqueos de soporte para el acceso a datos simultáneos.
-
-    Durante `INSERT` consultas, la tabla está bloqueada y otras consultas para leer y escribir datos esperan a que la tabla se desbloquee. Si no hay consultas de escritura de datos, se puede realizar cualquier número de consultas de lectura de datos simultáneamente.
-
--   No apoyo [mutación](../../../sql-reference/statements/alter.md#alter-mutations) operación.
-
--   No admite índices.
-
-    Esto significa que `SELECT` las consultas para rangos de datos no son eficientes.
-
--   No escriba datos atómicamente.
-
-    Puede obtener una tabla con datos dañados si algo rompe la operación de escritura, por ejemplo, un cierre anormal del servidor.
-
-## Diferencia {#differences}
-
-El `TinyLog` es el más simple de la familia y proporciona la funcionalidad más pobre y la eficiencia más baja. El `TinyLog` el motor no admite la lectura de datos paralelos por varios hilos. Lee datos más lentamente que otros motores de la familia que admiten lectura paralela y utiliza casi tantos descriptores como los `Log` motor porque almacena cada columna en un archivo separado. Úselo en escenarios simples de baja carga.
-
-El `Log` y `StripeLog` Los motores admiten lectura de datos paralela. Al leer datos, ClickHouse usa múltiples hilos. Cada subproceso procesa un bloque de datos separado. El `Log` utiliza un archivo separado para cada columna de la tabla. `StripeLog` almacena todos los datos en un archivo. Como resultado, el `StripeLog` el motor utiliza menos descriptores en el sistema operativo, pero el `Log` proporciona una mayor eficiencia al leer datos.

-
-# Registro {#log}
-
-El motor pertenece a la familia de motores de registro. Consulte las propiedades comunes de los motores de registro y sus diferencias en [Familia del motor de registro](index.md) artículo.
-
-El registro difiere de [TinyLog](tinylog.md) en que un pequeño archivo de “marks” reside con los archivos de columna. Estas marcas se escriben en cada bloque de datos y contienen compensaciones que indican dónde comenzar a leer el archivo para omitir el número especificado de filas. Esto hace posible leer datos de tabla en múltiples hilos.
-Para el acceso a datos simultáneos, las operaciones de lectura se pueden realizar simultáneamente, mientras que las operaciones de escritura bloquean las lecturas entre sí.
-El motor de registro no admite índices. Del mismo modo, si la escritura en una tabla falla, la tabla se rompe y la lectura de ella devuelve un error. El motor de registro es adecuado para datos temporales, tablas de escritura única y para fines de prueba o demostración.

-# Lista de Stripelog {#stripelog}
-
-Este motor pertenece a la familia de motores de registro. Consulte las propiedades comunes de los motores de registro y sus diferencias en [Familia del motor de registro](index.md) artículo.
-
-Utilice este motor en escenarios en los que necesite escribir muchas tablas con una pequeña cantidad de datos (menos de 1 millón de filas).
-
-## Creación de una tabla {#table_engines-stripelog-creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    column1_name [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    column2_name [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = StripeLog
-```
-
-Vea la descripción detallada del [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) consulta.
-
-## Escribir los datos {#table_engines-stripelog-writing-the-data}
-
-El `StripeLog` el motor almacena todas las columnas en un archivo. Para cada `INSERT` consulta, ClickHouse agrega el bloque de datos al final de un archivo de tabla, escribiendo columnas una por una.
-
-Para cada tabla, ClickHouse escribe los archivos:
-
--   `data.bin` — Data file.
--   `index.mrk` — File with marks. Marks contain offsets for each column of each data block inserted.
-
-El `StripeLog` el motor no soporta el `ALTER UPDATE` y `ALTER DELETE` operación.
-
-## Lectura de los datos {#table_engines-stripelog-reading-the-data}
-
-El archivo con marcas permite ClickHouse paralelizar la lectura de datos. Esto significa que un `SELECT` query devuelve filas en un orden impredecible. Utilice el `ORDER BY` cláusula para ordenar filas.
-
-## Ejemplo de uso {#table_engines-stripelog-example-of-use}
-
-Creación de una tabla:
-
-``` sql
-CREATE TABLE stripe_log_table
-(
-    timestamp DateTime,
-    message_type String,
-    message String
-)
-ENGINE = StripeLog
-```
-
-Insertar datos:
-
-``` sql
-INSERT INTO stripe_log_table VALUES (now(),'REGULAR','The first regular message')
-INSERT INTO stripe_log_table VALUES (now(),'REGULAR','The second regular message'),(now(),'WARNING','The first warning message')
-```
-
-Se utilizaron dos `INSERT` consultas para crear dos bloques de datos dentro del `data.bin` file.
-
-ClickHouse usa múltiples subprocesos al seleccionar datos. Cada subproceso lee un bloque de datos separado y devuelve las filas resultantes de forma independiente a medida que termina. Como resultado, el orden de los bloques de filas en la salida no coincide con el orden de los mismos bloques en la entrada en la mayoría de los casos. Por ejemplo:
-
-``` sql
-SELECT * FROM stripe_log_table
-```
-
-``` text
-┌───────────timestamp─┬─message_type─┬─message────────────────────┐
-│ 2019-01-18 14:27:32 │ REGULAR      │ The second regular message │
-│ 2019-01-18 14:34:53 │ WARNING      │ The first warning message  │
-└─────────────────────┴──────────────┴────────────────────────────┘
-┌───────────timestamp─┬─message_type─┬─message───────────────────┐
-│ 2019-01-18 14:23:43 │ REGULAR      │ The first regular message │
-└─────────────────────┴──────────────┴───────────────────────────┘
-```
-
-Ordenación de los resultados (orden ascendente por defecto):
-
-``` sql
-SELECT * FROM stripe_log_table ORDER BY timestamp
-```
-
-``` text
-┌───────────timestamp─┬─message_type─┬─message────────────────────┐

-│ 2019-01-18 14:27:32 │ REGULAR      │ The second regular message │
-│ 2019-01-18 14:34:53 │ WARNING      │ The first warning message  │

-# TinyLog {#tinylog}
-
-El motor pertenece a la familia de motores de registro. Ver [Familia del motor de registro](index.md) para las propiedades comunes de los motores de registro y sus diferencias.
-
-Este motor de tablas se usa normalmente con el método write-once: escribir datos una vez, luego leerlos tantas veces como sea necesario. Por ejemplo, puede usar `TinyLog`-type tablas para datos intermedios que se procesan en pequeños lotes. Tenga en cuenta que el almacenamiento de datos en un gran número de tablas pequeñas es ineficiente.
-
-Las consultas se ejecutan en una sola secuencia. En otras palabras, este motor está diseñado para tablas relativamente pequeñas (hasta aproximadamente 1,000,000 filas). Tiene sentido usar este motor de tablas si tiene muchas tablas pequeñas, ya que es más simple que el [Registro](log.md) motor (menos archivos necesitan ser abiertos).

-El motor hereda de [Método de codificación de datos:](mergetree.md#table_engines-mergetree), alterando la lógica para la fusión de partes de datos. ClickHouse reemplaza todas las filas con la misma clave principal (o más exactamente, con la misma [clave de clasificación](mergetree.md)) con una sola fila (dentro de una parte de datos) que almacena una combinación de estados de funciones agregadas.
-
-Usted puede utilizar `AggregatingMergeTree` tablas para la agregación de datos incrementales, incluidas las vistas materializadas agregadas.
-
-El motor procesa todas las columnas con los siguientes tipos:
-
--   [AggregateFunction](../../../sql-reference/data-types/aggregatefunction.md)
--   [SimpleAggregateFunction](../../../sql-reference/data-types/simpleaggregatefunction.md)
-
-Es apropiado usar `AggregatingMergeTree` si reduce el número de filas por pedidos.
-
-## Creación de una tabla {#creating-a-table}

-
-Todos los parámetros tienen el mismo significado que en `MergeTree`.

-
-## SELECCIONAR e INSERTAR {#select-and-insert}
-
-Para insertar datos, utilice [INSERT SELECT](../../../sql-reference/statements/insert-into.md) consulta con funciones agregadas -State-.
-Al seleccionar datos de `AggregatingMergeTree` mesa, uso `GROUP BY` cláusula y las mismas funciones agregadas que al insertar datos, pero usando `-Merge` sufijo.
-
-En los resultados de `SELECT` consulta, los valores de `AggregateFunction` tipo tiene representación binaria específica de la implementación para todos los formatos de salida de ClickHouse. Si volcar datos en, por ejemplo, `TabSeparated` formato con `SELECT` consulta entonces este volcado se puede cargar de nuevo usando `INSERT` consulta.
-
-## Ejemplo de una vista materializada agregada {#example-of-an-aggregated-materialized-view}
-
-`AggregatingMergeTree` vista materializada que mira el `test.visits` tabla:
-
-``` sql
-CREATE MATERIALIZED VIEW test.basic
-ENGINE = AggregatingMergeTree() PARTITION BY toYYYYMM(StartDate) ORDER BY (CounterID, StartDate)
-AS SELECT
-    CounterID,
-    StartDate,
-    sumState(Sign)    AS Visits,
-    uniqState(UserID) AS Users
-FROM test.visits
-GROUP BY CounterID, StartDate;
-```
-
-Insertar datos en el `test.visits` tabla.
-
-``` sql
-INSERT INTO test.visits ...
-```
-
-Los datos se insertan tanto en la tabla como en la vista `test.basic` que realizará la agregación.
-
-Para obtener los datos agregados, necesitamos ejecutar una consulta como `SELECT ... GROUP BY ...` de la vista `test.basic`:
-
-``` sql
-SELECT
-    StartDate,
-    sumMerge(Visits) AS Visits,
-    uniqMerge(Users) AS Users
-FROM test.basic
-GROUP BY StartDate
-ORDER BY StartDate;
-```

-
-El motor hereda de [Método de codificación de datos:](mergetree.md) y agrega la lógica de las filas que colapsan al algoritmo de fusión de partes de datos.
-
-`CollapsingMergeTree` elimina de forma asincrónica (colapsa) pares de filas si todos los campos de una clave de ordenación (`ORDER BY`) son equivalentes excepto el campo particular `Sign` que puede tener `1` y `-1` valor. Las filas sin un par se mantienen. Para más detalles, consulte el [Derrumbar](#table_engine-collapsingmergetree-collapsing) sección del documento.

-
-### Datos {#data}
-
-Considere la situación en la que necesita guardar datos que cambian continuamente para algún objeto. Parece lógico tener una fila para un objeto y actualizarla en cualquier cambio, pero la operación de actualización es costosa y lenta para DBMS porque requiere la reescritura de los datos en el almacenamiento. Si necesita escribir datos rápidamente, la actualización no es aceptable, pero puede escribir los cambios de un objeto secuencialmente de la siguiente manera.
-
-Utilice la columna en particular `Sign`. Si `Sign = 1` significa que la fila es un estado de un objeto, llamémoslo “state” fila. Si `Sign = -1` significa la cancelación del estado de un objeto con los mismos atributos, llamémoslo “cancel” fila.
-
-Por ejemplo, queremos calcular cuántas páginas revisaron los usuarios en algún sitio y cuánto tiempo estuvieron allí. En algún momento escribimos la siguiente fila con el estado de la actividad del usuario:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-En algún momento después registramos el cambio de actividad del usuario y lo escribimos con las siguientes dos filas.
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-La primera fila cancela el estado anterior del objeto (usuario). Debe copiar los campos clave de ordenación del estado cancelado exceptuando `Sign`.
-
-La segunda fila contiene el estado actual.
-
-Como solo necesitamos el último estado de actividad del usuario, las filas
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-│ 4324182021466249494 │         5 │      146 │   -1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-se puede eliminar colapsando el estado no válido (antiguo) de un objeto. `CollapsingMergeTree` hace esto mientras se fusionan las partes de datos.
-
-Por qué necesitamos 2 filas para cada cambio leído en el [Algoritmo](#table_engine-collapsingmergetree-collapsing-algorithm) apartado.
-
-**Propiedades peculiares de tal enfoque**
-
-1.  El programa que escribe los datos debe recordar el estado de un objeto para poder cancelarlo. “Cancel” debe contener copias de los campos de clave de ordenación “state” y lo opuesto `Sign`. Aumenta el tamaño inicial de almacenamiento, pero permite escribir los datos rápidamente.
-2.  Las matrices de largo crecimiento en columnas reducen la eficiencia del motor debido a la carga para escribir. Los datos más sencillos, mayor será la eficiencia.
-3.  El `SELECT` Los resultados dependen en gran medida de la consistencia del historial de cambios de objetos. Sea preciso al preparar los datos para insertarlos. Puede obtener resultados impredecibles en datos incoherentes, por ejemplo, valores negativos para métricas no negativas, como la profundidad de la sesión.
-
-### Algoritmo {#table_engine-collapsingmergetree-collapsing-algorithm}
-
-Cuando ClickHouse combina partes de datos, cada grupo de filas consecutivas tiene la misma clave de ordenación (`ORDER BY`) se reduce a no más de dos filas, una con `Sign = 1` (“state” fila) y otro con `Sign = -1` (“cancel” fila). En otras palabras, las entradas colapsan.
-
-Para cada parte de datos resultante, ClickHouse guarda:
-
-1.  El primero “cancel” y el último “state” si el número de “state” y “cancel” y la última fila es una “state” fila.
-2.  El último “state” fila, si hay más “state” filas que “cancel” filas.
-3.  El primero “cancel” fila, si hay más “cancel” filas que “state” filas.
-4.  Ninguna de las filas, en todos los demás casos.
-
-También cuando hay al menos 2 más “state” filas que “cancel” filas, o al menos 2 más “cancel” filas entonces “state” fila, la fusión continúa, pero ClickHouse trata esta situación como un error lógico y la registra en el registro del servidor. Este error puede producirse si se insertan los mismos datos más de una vez.
-
-Por lo tanto, el colapso no debe cambiar los resultados del cálculo de las estadísticas.
-Los cambios colapsaron gradualmente para que al final solo quedara el último estado de casi todos los objetos.
-
-El `Sign` se requiere porque el algoritmo de fusión no garantiza que todas las filas con la misma clave de clasificación estén en la misma parte de datos resultante e incluso en el mismo servidor físico. Proceso de ClickHouse `SELECT` consultas con múltiples hilos, y no puede predecir el orden de las filas en el resultado. La agregación es necesaria si hay una necesidad de obtener completamente “collapsed” datos de `CollapsingMergeTree` tabla.
-
-Para finalizar el colapso, escriba una consulta con `GROUP BY` cláusula y funciones agregadas que representan el signo. Por ejemplo, para calcular la cantidad, use `sum(Sign)` en lugar de `count()`. Para calcular la suma de algo, use `sum(Sign * x)` en lugar de `sum(x)` y así sucesivamente, y también añadir `HAVING sum(Sign) > 0`.
-
-Los agregados `count`, `sum` y `avg` podría calcularse de esta manera. El agregado `uniq` podría calcularse si un objeto tiene al menos un estado no colapsado. Los agregados `min` y `max` no se pudo calcular porque `CollapsingMergeTree` no guarda el historial de valores de los estados colapsados.
-
-Si necesita extraer datos sin agregación (por ejemplo, para comprobar si hay filas presentes cuyos valores más recientes coinciden con ciertas condiciones), puede utilizar el `FINAL` modificador para el `FROM` clausula. Este enfoque es significativamente menos eficiente.

-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Creación de la tabla:
-
-``` sql
-CREATE TABLE UAct
-(
-    UserID UInt64,
-    PageViews UInt8,
-    Duration UInt8,
-    Sign Int8
-)
-ENGINE = CollapsingMergeTree(Sign)
-ORDER BY UserID
-```
-
-Inserción de los datos:
-
-``` sql
-INSERT INTO UAct VALUES (4324182021466249494, 5, 146, 1)
-```
-
-``` sql
-INSERT INTO UAct VALUES (4324182021466249494, 5, 146, -1),(4324182021466249494, 6, 185, 1)
-```
-
-Usamos dos `INSERT` consultas para crear dos partes de datos diferentes. Si insertamos los datos con una consulta, ClickHouse crea una parte de datos y nunca realizará ninguna fusión.
-
-Obtener los datos:
-
-``` sql
-SELECT * FROM UAct
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘

-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-¿Qué vemos y dónde está colapsando?
-
-Con dos `INSERT` consultas, hemos creado 2 partes de datos. El `SELECT` la consulta se realizó en 2 hilos, y obtuvimos un orden aleatorio de filas. No se ha producido un colapso porque todavía no se había fusionado las partes de datos. ClickHouse fusiona parte de datos en un momento desconocido que no podemos predecir.
-
-Por lo tanto, necesitamos agregación:
-
-``` sql
-SELECT
-    UserID,
-    sum(PageViews * Sign) AS PageViews,
-    sum(Duration * Sign) AS Duration
-FROM UAct
-GROUP BY UserID
-HAVING sum(Sign) > 0
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┐
-│ 4324182021466249494 │         6 │      185 │
-└─────────────────────┴───────────┴──────────┘
-```
-
-Si no necesitamos agregación y queremos forzar el colapso, podemos usar `FINAL` modificador para `FROM` clausula.
-
-``` sql
-SELECT * FROM UAct FINAL
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Esta forma de seleccionar los datos es muy ineficiente. No lo use para mesas grandes.
-
-## Ejemplo de otro enfoque {#example-of-another-approach}
-
-Datos de ejemplo:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-│ 4324182021466249494 │        -5 │     -146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-La idea es que las fusiones tengan en cuenta solo los campos clave. Y en el “Cancel” línea podemos especificar valores negativos que igualan la versión anterior de la fila al sumar sin usar la columna Sign. Para este enfoque, es necesario cambiar el tipo de datos `PageViews`,`Duration` para almacenar valores negativos de UInt8 -\> Int16.
-
-``` sql
-CREATE TABLE UAct
-(
-    UserID UInt64,
-    PageViews Int16,
-    Duration Int16,
-    Sign Int8
-)
-ENGINE = CollapsingMergeTree(Sign)
-ORDER BY UserID
-```
-
-Vamos a probar el enfoque:
-
-``` sql
-insert into UAct values(4324182021466249494,  5,  146,  1);
-insert into UAct values(4324182021466249494, -5, -146, -1);
-insert into UAct values(4324182021466249494,  6,  185,  1);
-
-select * from UAct final; // avoid using final in production (just for a test or small tables)

-# Clave de partición personalizada {#custom-partitioning-key}
-
-La partición está disponible para el [Método de codificación de datos:](mergetree.md) mesas familiares (incluyendo [repetición](replication.md) tabla). [Vistas materializadas](../special/materializedview.md#materializedview) basado en tablas MergeTree soporte de particionamiento, también.
-
-Una partición es una combinación lógica de registros en una tabla por un criterio especificado. Puede establecer una partición por un criterio arbitrario, como por mes, por día o por tipo de evento. Cada partición se almacena por separado para simplificar las manipulaciones de estos datos. Al acceder a los datos, ClickHouse utiliza el subconjunto más pequeño de particiones posible.
-
-La partición se especifica en el `PARTITION BY expr` cláusula cuando [creando una tabla](mergetree.md#table_engine-mergetree-creating-a-table). La clave de partición puede ser cualquier expresión de las columnas de la tabla. Por ejemplo, para especificar la partición por mes, utilice la expresión `toYYYYMM(date_column)`:
-
-``` sql
-CREATE TABLE visits
-(
-    VisitDate Date,
-    Hour UInt8,
-    ClientID UUID
-)
-ENGINE = MergeTree()
-PARTITION BY toYYYYMM(VisitDate)
-ORDER BY Hour;
-```
-
-La clave de partición también puede ser una tupla de expresiones (similar a la [clave primaria](mergetree.md#primary-keys-and-indexes-in-queries)). Por ejemplo:
-
-``` sql
-ENGINE = ReplicatedCollapsingMergeTree('/clickhouse/tables/name', 'replica1', Sign)
-PARTITION BY (toMonday(StartDate), EventType)
-ORDER BY (CounterID, StartDate, intHash32(UserID));
-```
-
-En este ejemplo, establecemos la partición por los tipos de eventos que se produjeron durante la semana actual.
-
-Al insertar datos nuevos en una tabla, estos datos se almacenan como una parte separada (porción) ordenada por la clave principal. En 10-15 minutos después de insertar, las partes de la misma partición se fusionan en toda la parte.
-
-!!! info "INFO"
-    Una combinación solo funciona para partes de datos que tienen el mismo valor para la expresión de partición. Esto significa **no deberías hacer particiones demasiado granulares** (más de un millar de particiones). De lo contrario, el `SELECT` consulta funciona mal debido a un número excesivamente grande de archivos en el sistema de archivos y descriptores de archivos abiertos.
-
-Utilice el [sistema.parte](../../../operations/system-tables.md#system_tables-parts) tabla para ver las partes y particiones de la tabla. Por ejemplo, supongamos que tenemos un `visits` tabla con partición por mes. Vamos a realizar el `SELECT` consulta para el `system.parts` tabla:
-
-``` sql
-SELECT
-    partition,
-    name,
-    active
-FROM system.parts
-WHERE table = 'visits'
-```
-

-El `partition` columna contiene los nombres de las particiones. Hay dos particiones en este ejemplo: `201901` y `201902`. Puede utilizar este valor de columna para especificar el nombre de partición en [ALTER … PARTITION](#alter_manipulations-with-partitions) consulta.
-
-El `name` columna contiene los nombres de las partes de datos de partición. Puede utilizar esta columna para especificar el nombre de la pieza [ALTER ATTACH PART](#alter_attach-partition) consulta.
-
-Vamos a desglosar el nombre de la primera parte: `201901_1_3_1`:
-
--   `201901` es el nombre de la partición.
--   `1` es el número mínimo del bloque de datos.
--   `3` es el número máximo del bloque de datos.
--   `1` es el nivel de fragmento (la profundidad del árbol de fusión del que se forma).
-
-!!! info "INFO"
-    Las partes de las tablas de tipo antiguo tienen el nombre: `20190117_20190123_2_2_0` (fecha mínima - fecha máxima - número de bloque mínimo - número de bloque máximo - nivel).
-
-El `active` columna muestra el estado de la pieza. `1` está activo; `0` está inactivo. Las partes inactivas son, por ejemplo, las partes de origen que quedan después de fusionarse con una parte más grande. Las partes de datos dañadas también se indican como inactivas.
-
-Como puede ver en el ejemplo, hay varias partes separadas de la misma partición (por ejemplo, `201901_1_3_1` y `201901_1_9_2`). Esto significa que estas partes aún no están fusionadas. ClickHouse combina las partes insertadas de datos periódicamente, aproximadamente 15 minutos después de la inserción. Además, puede realizar una fusión no programada utilizando el [OPTIMIZE](../../../sql-reference/statements/misc.md#misc_operations-optimize) consulta. Ejemplo:
-
-``` sql
-OPTIMIZE TABLE visits PARTITION 201902;
-```
-
-``` text
-┌─partition─┬─name───────────┬─active─┐
-│ 201901    │ 201901_1_3_1   │      0 │
-│ 201901    │ 201901_1_9_2   │      1 │
-│ 201901    │ 201901_8_8_0   │      0 │
-│ 201901    │ 201901_9_9_0   │      0 │
-│ 201902    │ 201902_4_6_1   │      0 │
-│ 201902    │ 201902_4_11_2  │      1 │
-│ 201902    │ 201902_10_10_0 │      0 │
-│ 201902    │ 201902_11_11_0 │      0 │
-└───────────┴────────────────┴────────┘
-```
-
-Las partes inactivas se eliminarán aproximadamente 10 minutos después de la fusión.
-
-Otra forma de ver un conjunto de partes y particiones es ir al directorio de la tabla: `/var/lib/clickhouse/data/<database>/<table>/`. Por ejemplo:
-
-``` bash
-/var/lib/clickhouse/data/default/visits$ ls -l
-total 40
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  1 16:48 201901_1_3_1
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:17 201901_1_9_2
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 15:52 201901_8_8_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 15:52 201901_9_9_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:17 201902_10_10_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:17 201902_11_11_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:19 201902_4_11_2
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 12:09 201902_4_6_1
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  1 16:48 detached
-```
-
-Carpeta ‘201901_1_1_0’, ‘201901_1_7_1’ y así sucesivamente son los directorios de las partes. Cada parte se relaciona con una partición correspondiente y contiene datos solo para un mes determinado (la tabla de este ejemplo tiene particiones por mes).
-
-El `detached` el directorio contiene partes que se separaron de la tabla utilizando el [DETACH](../../../sql-reference/statements/alter.md#alter_detach-partition) consulta. Las partes dañadas también se mueven a este directorio, en lugar de eliminarse. El servidor no utiliza las piezas del `detached` directory. You can add, delete, or modify the data in this directory at any time – the server will not know about this until you run the [ATTACH](../../../sql-reference/statements/alter.md#alter_attach-partition) consulta.
-
-Tenga en cuenta que en el servidor operativo, no puede cambiar manualmente el conjunto de piezas o sus datos en el sistema de archivos, ya que el servidor no lo sabrá. Para tablas no replicadas, puede hacer esto cuando se detiene el servidor, pero no se recomienda. Para tablas replicadas, el conjunto de piezas no se puede cambiar en ningún caso.
-
-ClickHouse le permite realizar operaciones con las particiones: eliminarlas, copiar de una tabla a otra o crear una copia de seguridad. Consulte la lista de todas las operaciones en la sección [Manipulaciones con particiones y piezas](../../../sql-reference/statements/alter.md#alter_manipulations-with-partitions).

-# GraphiteMergeTree {#graphitemergetree}
-
-Este motor está diseñado para el adelgazamiento y la agregación / promedio (rollup) [Grafito](http://graphite.readthedocs.io/en/latest/index.html) datos. Puede ser útil para los desarrolladores que desean usar ClickHouse como almacén de datos para Graphite.
-
-Puede usar cualquier motor de tabla ClickHouse para almacenar los datos de Graphite si no necesita un paquete acumulativo, pero si necesita un paquete acumulativo, use `GraphiteMergeTree`. El motor reduce el volumen de almacenamiento y aumenta la eficiencia de las consultas de Graphite.
-
-El motor hereda propiedades de [Método de codificación de datos:](mergetree.md).
-
-## Creación de una tabla {#creating-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    Path String,
-    Time DateTime,
-    Value <Numeric_type>,
-    Version <Numeric_type>
-    ...
-) ENGINE = GraphiteMergeTree(config_section)
-[PARTITION BY expr]
-[ORDER BY expr]
-[SAMPLE BY expr]
-[SETTINGS name=value, ...]
-```
-
-Vea una descripción detallada del [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) consulta.
-
-Una tabla para los datos de grafito debe tener las siguientes columnas para los siguientes datos:
-
--   Nombre métrico (sensor de grafito). Tipo de datos: `String`.
-
--   Tiempo de medición de la métrica. Tipo de datos: `DateTime`.
-
--   Valor de la métrica. Tipo de datos: cualquier numérico.
-
--   Versión de la métrica. Tipo de datos: cualquier numérico.
-
-    ClickHouse guarda las filas con la versión más alta o la última escrita si las versiones son las mismas. Otras filas se eliminan durante la fusión de partes de datos.
-
-Los nombres de estas columnas deben establecerse en la configuración acumulativa.
-
-**GraphiteMergeTree parámetros**
-
--   `config_section` — Name of the section in the configuration file, where are the rules of rollup set.
-
-**Cláusulas de consulta**
-
-Al crear un `GraphiteMergeTree` mesa, la misma [clausula](mergetree.md#table_engine-mergetree-creating-a-table) se requieren, como al crear un `MergeTree` tabla.

-
-Todos los parámetros excepto `config_section` el mismo significado que en `MergeTree`.
-
--   `config_section` — Name of the section in the configuration file, where are the rules of rollup set.
-

-
-## Configuración acumulativa {#rollup-configuration}
-
-La configuración del paquete acumulativo está definida por [graphite_rollup](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-graphite) parámetro en la configuración del servidor. El nombre del parámetro podría ser cualquiera. Puede crear varias configuraciones y usarlas para diferentes tablas.
-
-Estructura de configuración Rollup:
-
-      required-columns
-      patterns
-
-### Columnas requeridas {#required-columns}
-
--   `path_column_name` — The name of the column storing the metric name (Graphite sensor). Default value: `Path`.
--   `time_column_name` — The name of the column storing the time of measuring the metric. Default value: `Time`.
--   `value_column_name` — The name of the column storing the value of the metric at the time set in `time_column_name`. Valor predeterminado: `Value`.
--   `version_column_name` — The name of the column storing the version of the metric. Default value: `Timestamp`.
-
-### Patrón {#patterns}
-
-Estructura del `patterns` apartado:
-
-``` text

-    regexp
-    function
-pattern
-    regexp

-    ...
-pattern
-    regexp
-    function
-    age + precision
-    ...
-pattern
-    ...
-default
-    function
-    age + precision
-    ...
-```
-
-!!! warning "Atención"
-    Los patrones deben ser estrictamente ordenados:
-
-      1. Patterns without `function` or `retention`.
-      1. Patterns with both `function` and `retention`.
-      1. Pattern `default`.
-
-Al procesar una fila, ClickHouse comprueba las reglas en el `pattern` apartado. Cada uno de `pattern` (incluir `default` secciones pueden contener `function` parámetro para la agregación, `retention` parámetros o ambos. Si el nombre de la métrica coincide con `regexp`, las reglas de la `pattern` sección (o secciones); de lo contrario, las reglas de la `default` sección se utilizan.
-
-Campos para `pattern` y `default` apartado:
-
--   `regexp`– A pattern for the metric name.
--   `age` – The minimum age of the data in seconds.
--   `precision`– How precisely to define the age of the data in seconds. Should be a divisor for 86400 (seconds in a day).
--   `function` – The name of the aggregating function to apply to data whose age falls within the range `[age, age + precision]`.

-
-# Método de codificación de datos: {#table_engines-mergetree}
-
-El `MergeTree` motor y otros motores de esta familia (`*MergeTree`) son los motores de mesa ClickHouse más robustos.
-
-Motores en el `MergeTree` familia están diseñados para insertar una gran cantidad de datos en una tabla. Los datos se escriben rápidamente en la tabla parte por parte, luego se aplican reglas para fusionar las partes en segundo plano. Este método es mucho más eficiente que reescribir continuamente los datos en almacenamiento durante la inserción.
-
-Principales características:
-
--   Almacena datos ordenados por clave principal.
-
-    Esto le permite crear un pequeño índice disperso que ayuda a encontrar datos más rápido.
-
--   Las particiones se pueden utilizar si [clave de partición](custom-partitioning-key.md) se especifica.
-
-    ClickHouse admite ciertas operaciones con particiones que son más efectivas que las operaciones generales en los mismos datos con el mismo resultado. ClickHouse también corta automáticamente los datos de partición donde se especifica la clave de partición en la consulta. Esto también mejora el rendimiento de las consultas.
-
--   Soporte de replicación de datos.
-
-    La familia de `ReplicatedMergeTree` proporciona la replicación de datos. Para obtener más información, consulte [Replicación de datos](replication.md).
-
--   Soporte de muestreo de datos.
-
-    Si es necesario, puede establecer el método de muestreo de datos en la tabla.
-
-!!! info "INFO"
-    El [Fusionar](../special/merge.md#merge) el motor no pertenece al `*MergeTree` familia.

-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
-    ...

-[ORDER BY expr]
-[PRIMARY KEY expr]
-[SAMPLE BY expr]
-[TTL expr [DELETE|TO DISK 'xxx'|TO VOLUME 'xxx'], ...]
-[SETTINGS name=value, ...]
-```
-
-Para obtener una descripción de los parámetros, consulte [Descripción de la consulta CREATE](../../../sql-reference/statements/create.md).
-
-!!! note "Nota"
-    `INDEX` es una característica experimental, ver [Índices de saltos de datos](#table_engine-mergetree-data_skipping-indexes).
-
-### Cláusulas de consulta {#mergetree-query-clauses}
-
--   `ENGINE` — Name and parameters of the engine. `ENGINE = MergeTree()`. El `MergeTree` el motor no tiene parámetros.
-
--   `PARTITION BY` — The [clave de partición](custom-partitioning-key.md).
-
-    Para particionar por mes, utilice el `toYYYYMM(date_column)` expresión, donde `date_column` es una columna con una fecha del tipo [Fecha](../../../sql-reference/data-types/date.md). Los nombres de partición aquí tienen el `"YYYYMM"` formato.
-
--   `ORDER BY` — The sorting key.
-
-    Una tupla de columnas o expresiones arbitrarias. Ejemplo: `ORDER BY (CounterID, EventDate)`.
-
--   `PRIMARY KEY` — The primary key if it [difiere de la clave de clasificación](#choosing-a-primary-key-that-differs-from-the-sorting-key).
-
-    De forma predeterminada, la clave principal es la misma que la clave de ordenación (que se especifica `ORDER BY` clausula). Por lo tanto, en la mayoría de los casos no es necesario especificar un `PRIMARY KEY` clausula.
-
--   `SAMPLE BY` — An expression for sampling.
-
-    Si se utiliza una expresión de muestreo, la clave principal debe contenerla. Ejemplo: `SAMPLE BY intHash32(UserID) ORDER BY (CounterID, EventDate, intHash32(UserID))`.
-
--   `TTL` — A list of rules specifying storage duration of rows and defining logic of automatic parts movement [entre discos y volúmenes](#table_engine-mergetree-multiple-volumes).
-
-    La expresión debe tener una `Date` o `DateTime` columna como resultado. Ejemplo:
-    `TTL date + INTERVAL 1 DAY`
-
-    Tipo de regla `DELETE|TO DISK 'xxx'|TO VOLUME 'xxx'` especifica una acción que debe realizarse con la pieza si la expresión está satisfecha (alcanza la hora actual): eliminación de filas caducadas, mover una pieza (si la expresión está satisfecha para todas las filas de una pieza) al disco especificado (`TO DISK 'xxx'`) o al volumen (`TO VOLUME 'xxx'`). El tipo predeterminado de la regla es la eliminación (`DELETE`). Se puede especificar una lista de varias reglas, pero no debe haber más de una `DELETE` regla.
-
-    Para obtener más información, consulte [TTL para columnas y tablas](#table_engine-mergetree-ttl)
-
--   `SETTINGS` — Additional parameters that control the behavior of the `MergeTree`:
-
-    -   `index_granularity` — Maximum number of data rows between the marks of an index. Default value: 8192. See [Almacenamiento de datos](#mergetree-data-storage).
-    -   `index_granularity_bytes` — Maximum size of data granules in bytes. Default value: 10Mb. To restrict the granule size only by number of rows, set to 0 (not recommended). See [Almacenamiento de datos](#mergetree-data-storage).
-    -   `enable_mixed_granularity_parts` — Enables or disables transitioning to control the granule size with the `index_granularity_bytes` configuración. Antes de la versión 19.11, sólo existía el `index_granularity` ajuste para restringir el tamaño del gránulo. El `index_granularity_bytes` mejora el rendimiento de ClickHouse al seleccionar datos de tablas con filas grandes (decenas y cientos de megabytes). Si tiene tablas con filas grandes, puede habilitar esta configuración para que las tablas mejoren la eficiencia de `SELECT` consulta.
-    -   `use_minimalistic_part_header_in_zookeeper` — Storage method of the data parts headers in ZooKeeper. If `use_minimalistic_part_header_in_zookeeper=1`, entonces ZooKeeper almacena menos datos. Para obtener más información, consulte [descripción del ajuste](../../../operations/server-configuration-parameters/settings.md#server-settings-use_minimalistic_part_header_in_zookeeper) en “Server configuration parameters”.
-    -   `min_merge_bytes_to_use_direct_io` — The minimum data volume for merge operation that is required for using direct I/O access to the storage disk. When merging data parts, ClickHouse calculates the total storage volume of all the data to be merged. If the volume exceeds `min_merge_bytes_to_use_direct_io` bytes, ClickHouse lee y escribe los datos en el disco de almacenamiento utilizando la interfaz de E / S directa (`O_DIRECT` opcion). Si `min_merge_bytes_to_use_direct_io = 0`, entonces la E/S directa está deshabilitada. Valor predeterminado: `10 * 1024 * 1024 * 1024` byte.
-        <a name="mergetree_setting-merge_with_ttl_timeout"></a>
-    -   `merge_with_ttl_timeout` — Minimum delay in seconds before repeating a merge with TTL. Default value: 86400 (1 day).
-    -   `write_final_mark` — Enables or disables writing the final index mark at the end of data part (after the last byte). Default value: 1. Don't turn it off.
-    -   `merge_max_block_size` — Maximum number of rows in block for merge operations. Default value: 8192.
-    -   `storage_policy` — Storage policy. See [Uso de varios dispositivos de bloque para el almacenamiento de datos](#table_engine-mergetree-multiple-volumes).
-
-**Ejemplo de configuración de secciones**
-
-``` sql
-ENGINE MergeTree() PARTITION BY toYYYYMM(EventDate) ORDER BY (CounterID, EventDate, intHash32(UserID)) SAMPLE BY intHash32(UserID) SETTINGS index_granularity=8192
-```
-
-En el ejemplo, configuramos la partición por mes.
-
-También establecemos una expresión para el muestreo como un hash por el ID de usuario. Esto le permite pseudoaleatorizar los datos en la tabla para cada `CounterID` y `EventDate`. Si define un [SAMPLE](../../../sql-reference/statements/select/sample.md#select-sample-clause) cláusula al seleccionar los datos, ClickHouse devolverá una muestra de datos pseudoaleatoria uniforme para un subconjunto de usuarios.
-
-El `index_granularity` se puede omitir porque 8192 es el valor predeterminado.

-
-<summary>Método obsoleto para crear una tabla</summary>
-
-!!! attention "Atención"
-    No utilice este método en nuevos proyectos. Si es posible, cambie los proyectos antiguos al método descrito anteriormente.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE [=] MergeTree(date-column [, sampling_expression], (primary, key), index_granularity)
-```
-
-**Parámetros MergeTree()**
-
--   `date-column` — The name of a column of the [Fecha](../../../sql-reference/data-types/date.md) tipo. ClickHouse crea automáticamente particiones por mes en función de esta columna. Los nombres de partición están en el `"YYYYMM"` formato.
--   `sampling_expression` — An expression for sampling.
--   `(primary, key)` — Primary key. Type: [Tupla()](../../../sql-reference/data-types/tuple.md)
--   `index_granularity` — The granularity of an index. The number of data rows between the “marks” de un índice. El valor 8192 es apropiado para la mayoría de las tareas.
-
-**Ejemplo**
-
-``` sql
-MergeTree(EventDate, intHash32(UserID), (CounterID, EventDate, intHash32(UserID)), 8192)
-```
-
-El `MergeTree` engine se configura de la misma manera que en el ejemplo anterior para el método de configuración del motor principal.
-</details>
-
-## Almacenamiento de datos {#mergetree-data-storage}
-
-Una tabla consta de partes de datos ordenadas por clave principal.
-
-Cuando se insertan datos en una tabla, se crean partes de datos separadas y cada una de ellas se ordena lexicográficamente por clave principal. Por ejemplo, si la clave principal es `(CounterID, Date)`, los datos en la parte se ordenan por `CounterID`, y dentro de cada `CounterID` es ordenado por `Date`.
-
-Los datos que pertenecen a diferentes particiones se separan en diferentes partes. En el fondo, ClickHouse combina partes de datos para un almacenamiento más eficiente. Las piezas que pertenecen a particiones diferentes no se fusionan. El mecanismo de combinación no garantiza que todas las filas con la misma clave principal estén en la misma parte de datos.
-
-Cada parte de datos se divide lógicamente en gránulos. Un gránulo es el conjunto de datos indivisibles más pequeño que ClickHouse lee al seleccionar datos. ClickHouse no divide filas o valores, por lo que cada gránulo siempre contiene un número entero de filas. La primera fila de un gránulo está marcada con el valor de la clave principal de la fila. Para cada parte de datos, ClickHouse crea un archivo de índice que almacena las marcas. Para cada columna, ya sea en la clave principal o no, ClickHouse también almacena las mismas marcas. Estas marcas le permiten encontrar datos directamente en archivos de columnas.
-
-El tamaño del gránulo es restringido por `index_granularity` y `index_granularity_bytes` configuración del motor de tabla. El número de filas en un gránulo se encuentra en el `[1, index_granularity]` rango, dependiendo del tamaño de las filas. El tamaño de un gránulo puede exceder `index_granularity_bytes` si el tamaño de una sola fila es mayor que el valor de la configuración. En este caso, el tamaño del gránulo es igual al tamaño de la fila.
-
-## Claves e índices principales en consultas {#primary-keys-and-indexes-in-queries}
-
-Tome el `(CounterID, Date)` clave primaria como ejemplo. En este caso, la clasificación y el índice se pueden ilustrar de la siguiente manera:
-
-      Whole data:     [---------------------------------------------]
-      CounterID:      [aaaaaaaaaaaaaaaaaabbbbcdeeeeeeeeeeeeefgggggggghhhhhhhhhiiiiiiiiikllllllll]
-      Date:           [1111111222222233331233211111222222333211111112122222223111112223311122333]
-      Marks:           |      |      |      |      |      |      |      |      |      |      |
-                      a,1    a,2    a,3    b,3    e,2    e,3    g,1    h,2    i,1    i,3    l,3
-      Marks numbers:   0      1      2      3      4      5      6      7      8      9      10
-
-Si la consulta de datos especifica:
-
--   `CounterID in ('a', 'h')`, el servidor lee los datos en los rangos de marcas `[0, 3)` y `[6, 8)`.
--   `CounterID IN ('a', 'h') AND Date = 3`, el servidor lee los datos en los rangos de marcas `[1, 3)` y `[7, 8)`.
--   `Date = 3`, el servidor lee los datos en el rango de marcas `[1, 10]`.
-
-Los ejemplos anteriores muestran que siempre es más efectivo usar un índice que un análisis completo.
-
-Un índice disperso permite leer datos adicionales. Al leer un único rango de la clave primaria, hasta `index_granularity * 2` se pueden leer filas adicionales en cada bloque de datos.
-
-Los índices dispersos le permiten trabajar con una gran cantidad de filas de tabla, porque en la mayoría de los casos, dichos índices caben en la RAM de la computadora.
-
-ClickHouse no requiere una clave principal única. Puede insertar varias filas con la misma clave principal.
-
-### Selección de la clave principal {#selecting-the-primary-key}
-
-El número de columnas en la clave principal no está explícitamente limitado. Dependiendo de la estructura de datos, puede incluir más o menos columnas en la clave principal. Esto puede:
-
--   Mejorar el rendimiento de un índice.
-
-    Si la clave principal es `(a, b)`, a continuación, añadir otra columna `c` mejorará el rendimiento si se cumplen las siguientes condiciones:
-
-    -   Hay consultas con una condición en la columna `c`.
-    -   Rangos de datos largos (varias veces más `index_granularity`) con valores idénticos para `(a, b)` son comunes. En otras palabras, al agregar otra columna le permite omitir rangos de datos bastante largos.
-
--   Mejorar la compresión de datos.
-
-    ClickHouse ordena los datos por clave principal, por lo que cuanto mayor sea la consistencia, mejor será la compresión.
-
--   Proporcione una lógica adicional al fusionar partes de datos en el [ColapsarMergeTree](collapsingmergetree.md#table_engine-collapsingmergetree) y [SummingMergeTree](summingmergetree.md) motor.
-
-    En este caso tiene sentido especificar el *clave de clasificación* que es diferente de la clave principal.
-
-Una clave principal larga afectará negativamente al rendimiento de la inserción y al consumo de memoria, pero las columnas adicionales de la clave principal no afectarán al rendimiento de ClickHouse durante `SELECT` consulta.
-
-### Elegir una clave principal que difiere de la clave de ordenación {#choosing-a-primary-key-that-differs-from-the-sorting-key}
-
-Es posible especificar una clave principal (una expresión con valores que se escriben en el archivo de índice para cada marca) que es diferente de la clave de ordenación (una expresión para ordenar las filas en partes de datos). En este caso, la tupla de expresión de clave primaria debe ser un prefijo de la tupla de expresión de clave de ordenación.
-
-Esta característica es útil cuando se [SummingMergeTree](summingmergetree.md) y
-[AgregaciónMergeTree](aggregatingmergetree.md) motores de mesa. En un caso común cuando se utilizan estos motores, la tabla tiene dos tipos de columnas: *cota* y *medida*. Las consultas típicas agregan valores de columnas de medida con `GROUP BY` y filtrado por dimensiones. Debido a que SummingMergeTree y AggregatingMergeTree agregan filas con el mismo valor de la clave de ordenación, es natural agregarle todas las dimensiones. Como resultado, la expresión de clave consta de una larga lista de columnas y esta lista debe actualizarse con frecuencia con las dimensiones recién agregadas.
-
-En este caso, tiene sentido dejar solo unas pocas columnas en la clave principal que proporcionarán análisis de rango eficientes y agregarán las columnas de dimensión restantes a la tupla de clave de clasificación.
-
-[ALTER](../../../sql-reference/statements/alter.md) de la clave de ordenación es una operación ligera porque cuando se agrega una nueva columna simultáneamente a la tabla y a la clave de ordenación, las partes de datos existentes no necesitan ser cambiadas. Dado que la clave de ordenación anterior es un prefijo de la nueva clave de ordenación y no hay datos en la columna recién agregada, los datos se ordenan tanto por las claves de ordenación antiguas como por las nuevas en el momento de la modificación de la tabla.
-
-### Uso de índices y particiones en consultas {#use-of-indexes-and-partitions-in-queries}
-
-Para `SELECT` consultas, ClickHouse analiza si se puede usar un índice. Se puede usar un índice si el `WHERE/PREWHERE` clause tiene una expresión (como uno de los elementos de conjunción, o enteramente) que representa una operación de comparación de igualdad o desigualdad, o si tiene `IN` o `LIKE` con un prefijo fijo en columnas o expresiones que están en la clave principal o clave de partición, o en ciertas funciones parcialmente repetitivas de estas columnas, o relaciones lógicas de estas expresiones.
-
-Por lo tanto, es posible ejecutar rápidamente consultas en uno o varios rangos de la clave principal. En este ejemplo, las consultas serán rápidas cuando se ejecuten para una etiqueta de seguimiento específica, para una etiqueta y un intervalo de fechas específicos, para una etiqueta y una fecha específicas, para varias etiquetas con un intervalo de fechas, etc.
-
-Veamos el motor configurado de la siguiente manera:
-
-      ENGINE MergeTree() PARTITION BY toYYYYMM(EventDate) ORDER BY (CounterID, EventDate) SETTINGS index_granularity=8192
-
-En este caso, en consultas:
-
-``` sql
-SELECT count() FROM table WHERE EventDate = toDate(now()) AND CounterID = 34
-SELECT count() FROM table WHERE EventDate = toDate(now()) AND (CounterID = 34 OR CounterID = 42)
-SELECT count() FROM table WHERE ((EventDate >= toDate('2014-01-01') AND EventDate <= toDate('2014-01-31')) OR EventDate = toDate('2014-05-01')) AND CounterID IN (101500, 731962, 160656) AND (CounterID = 101500 OR EventDate != toDate('2014-05-01'))
-```
-
-ClickHouse utilizará el índice de clave principal para recortar datos incorrectos y la clave de partición mensual para recortar particiones que están en intervalos de fechas incorrectos.
-
-Las consultas anteriores muestran que el índice se usa incluso para expresiones complejas. La lectura de la tabla está organizada de modo que el uso del índice no puede ser más lento que un escaneo completo.
-
-En el siguiente ejemplo, el índice no se puede usar.
-
-``` sql
-SELECT count() FROM table WHERE CounterID = 34 OR URL LIKE '%upyachka%'
-```
-
-Para comprobar si ClickHouse puede usar el índice al ejecutar una consulta, use la configuración [Fecha de nacimiento](../../../operations/settings/settings.md#settings-force_index_by_date) y [force_primary_key](../../../operations/settings/settings.md).
-
-La clave para particionar por mes permite leer solo aquellos bloques de datos que contienen fechas del rango adecuado. En este caso, el bloque de datos puede contener datos para muchas fechas (hasta un mes). Dentro de un bloque, los datos se ordenan por clave principal, que puede no contener la fecha como la primera columna. Debido a esto, el uso de una consulta con solo una condición de fecha que no especifica el prefijo de clave principal hará que se lean más datos que para una sola fecha.
-
-### Uso del índice para claves primarias parcialmente monótonas {#use-of-index-for-partially-monotonic-primary-keys}
-
-Considere, por ejemplo, los días del mes. Ellos forman un [monótona secuencia](https://en.wikipedia.org/wiki/Monotonic_function) durante un mes, pero no monótono durante períodos más prolongados. Esta es una secuencia parcialmente monotónica. Si un usuario crea la tabla con clave primaria parcialmente monótona, ClickHouse crea un índice disperso como de costumbre. Cuando un usuario selecciona datos de este tipo de tabla, ClickHouse analiza las condiciones de consulta. Si el usuario desea obtener datos entre dos marcas del índice y ambas marcas caen dentro de un mes, ClickHouse puede usar el índice en este caso particular porque puede calcular la distancia entre los parámetros de una consulta y las marcas de índice.
-
-ClickHouse no puede usar un índice si los valores de la clave principal en el rango de parámetros de consulta no representan una secuencia monotónica. En este caso, ClickHouse utiliza el método de análisis completo.
-
-ClickHouse usa esta lógica no solo para secuencias de días del mes, sino para cualquier clave principal que represente una secuencia parcialmente monotónica.
-
-### Índices de saltos de datos (experimental) {#table_engine-mergetree-data_skipping-indexes}
-
-La declaración de índice se encuentra en la sección de columnas del `CREATE` consulta.
-
-``` sql
-INDEX index_name expr TYPE type(...) GRANULARITY granularity_value
-```
-
-Para tablas de la `*MergeTree` familia, se pueden especificar índices de omisión de datos.
-
-Estos índices agregan cierta información sobre la expresión especificada en bloques, que consisten en `granularity_value` gránulos (el tamaño del gránulo se especifica utilizando el `index_granularity` ajuste en el motor de la tabla). Entonces estos agregados se usan en `SELECT` consultas para reducir la cantidad de datos a leer desde el disco omitiendo grandes bloques de datos donde el `where` consulta no puede ser satisfecha.
-
-**Ejemplo**
-
-``` sql
-CREATE TABLE table_name
-(
-    u64 UInt64,
-    i32 Int32,
-    s String,
-    ...
-    INDEX a (u64 * i32, s) TYPE minmax GRANULARITY 3,
-    INDEX b (u64 * length(s)) TYPE set(1000) GRANULARITY 4
-) ENGINE = MergeTree()
-...
-```
-
-ClickHouse puede utilizar los índices del ejemplo para reducir la cantidad de datos que se leen desde el disco en las siguientes consultas:
-
-``` sql
-SELECT count() FROM table WHERE s < 'z'
-SELECT count() FROM table WHERE u64 * i32 == 10 AND u64 * length(s) >= 1234
-```
-
-#### Tipos de índices disponibles {#available-types-of-indices}
-
--   `minmax`
-
-    Almacena los extremos de la expresión especificada (si la expresión `tuple`, entonces almacena extremos para cada elemento de `tuple`), utiliza información almacenada para omitir bloques de datos como la clave principal.
-
--   `set(max_rows)`
-
-    Almacena valores únicos de la expresión especificada (no más de `max_rows` filas, `max_rows=0` medio “no limits”). Utiliza los valores para comprobar si `WHERE` expresión no es satisfactorio en un bloque de datos.
-
--   `ngrambf_v1(n, size_of_bloom_filter_in_bytes, number_of_hash_functions, random_seed)`
-
-    Tiendas a [Filtro de floración](https://en.wikipedia.org/wiki/Bloom_filter) que contiene todos los ngrams de un bloque de datos. Funciona solo con cadenas. Puede ser utilizado para la optimización de `equals`, `like` y `in` expresiones.
-
-    -   `n` — ngram size,
-    -   `size_of_bloom_filter_in_bytes` — Bloom filter size in bytes (you can use large values here, for example, 256 or 512, because it can be compressed well).
-    -   `number_of_hash_functions` — The number of hash functions used in the Bloom filter.
-    -   `random_seed` — The seed for Bloom filter hash functions.
-
--   `tokenbf_v1(size_of_bloom_filter_in_bytes, number_of_hash_functions, random_seed)`
-
-    Lo mismo que `ngrambf_v1`, pero almacena tokens en lugar de ngrams. Los tokens son secuencias separadas por caracteres no alfanuméricos.
-
--   `bloom_filter([false_positive])` — Stores a [Filtro de floración](https://en.wikipedia.org/wiki/Bloom_filter) para las columnas especificadas.
-
-    Opcional `false_positive` parámetro es la probabilidad de recibir una respuesta falsa positiva del filtro. Valores posibles: (0, 1). Valor predeterminado: 0.025.
-
-    Tipos de datos admitidos: `Int*`, `UInt*`, `Float*`, `Enum`, `Date`, `DateTime`, `String`, `FixedString`, `Array`, `LowCardinality`, `Nullable`.
-
-    Las siguientes funciones pueden usarlo: [igual](../../../sql-reference/functions/comparison-functions.md), [notEquals](../../../sql-reference/functions/comparison-functions.md), [en](../../../sql-reference/functions/in-functions.md), [noEn](../../../sql-reference/functions/in-functions.md), [tener](../../../sql-reference/functions/array-functions.md).
-
-<!-- -->
-
-``` sql
-INDEX sample_index (u64 * length(s)) TYPE minmax GRANULARITY 4
-INDEX sample_index2 (u64 * length(str), i32 + f64 * 100, date, str) TYPE set(100) GRANULARITY 4
-INDEX sample_index3 (lower(str), str) TYPE ngrambf_v1(3, 256, 2, 0) GRANULARITY 4
-```
-
-#### Funciones de apoyo {#functions-support}
-
-Condiciones en el `WHERE` cláusula contiene llamadas de las funciones que operan con columnas. Si la columna forma parte de un índice, ClickHouse intenta usar este índice al realizar las funciones. ClickHouse admite diferentes subconjuntos de funciones para usar índices.
-
-El `set` index se puede utilizar con todas las funciones. Subconjuntos de funciones para otros índices se muestran en la siguiente tabla.
-

-
-Las funciones con un argumento constante que es menor que el tamaño de ngram no pueden ser utilizadas por `ngrambf_v1` para la optimización de consultas.
-
-Los filtros Bloom pueden tener coincidencias falsas positivas, por lo que `ngrambf_v1`, `tokenbf_v1`, y `bloom_filter` los índices no se pueden usar para optimizar consultas donde se espera que el resultado de una función sea falso, por ejemplo:
-
--   Puede ser optimizado:
-    -   `s LIKE '%test%'`
-    -   `NOT s NOT LIKE '%test%'`
-    -   `s = 1`
-    -   `NOT s != 1`
-    -   `startsWith(s, 'test')`
--   No se puede optimizar:
-    -   `NOT s LIKE '%test%'`
-    -   `s NOT LIKE '%test%'`
-    -   `NOT s = 1`
-    -   `s != 1`
-    -   `NOT startsWith(s, 'test')`
-
-## Acceso a datos simultáneos {#concurrent-data-access}
-
-Para el acceso simultáneo a tablas, usamos versiones múltiples. En otras palabras, cuando una tabla se lee y actualiza simultáneamente, los datos se leen de un conjunto de partes que está actualizado en el momento de la consulta. No hay cerraduras largas. Las inserciones no se interponen en el camino de las operaciones de lectura.
-
-La lectura de una tabla se paralela automáticamente.
-
-## TTL para columnas y tablas {#table_engine-mergetree-ttl}
-
-Determina la duración de los valores.
-
-El `TTL` se puede establecer para toda la tabla y para cada columna individual. TTL de nivel de tabla también puede especificar la lógica de movimiento automático de datos entre discos y volúmenes.
-
-Las expresiones deben evaluar [Fecha](../../../sql-reference/data-types/date.md) o [FechaHora](../../../sql-reference/data-types/datetime.md) tipo de datos.
-
-Ejemplo:
-
-``` sql
-TTL time_column
-TTL time_column + interval
-```
-
-Definir `interval`, utilizar [intervalo de tiempo](../../../sql-reference/operators/index.md#operators-datetime) operador.
-
-``` sql
-TTL date_time + INTERVAL 1 MONTH
-TTL date_time + INTERVAL 15 HOUR
-```
-
-### Columna TTL {#mergetree-column-ttl}
-
-Cuando los valores de la columna caducan, ClickHouse los reemplaza con los valores predeterminados para el tipo de datos de columna. Si todos los valores de columna en la parte de datos caducan, ClickHouse elimina esta columna de la parte de datos en un sistema de archivos.
-
-El `TTL` cláusula no se puede utilizar para columnas clave.
-
-Ejemplos:
-
-Creación de una tabla con TTL
-
-``` sql
-CREATE TABLE example_table
-(
-    d DateTime,
-    a Int TTL d + INTERVAL 1 MONTH,
-    b Int TTL d + INTERVAL 1 MONTH,
-    c String
-)
-ENGINE = MergeTree
-PARTITION BY toYYYYMM(d)
-ORDER BY d;
-```
-
-Adición de TTL a una columna de una tabla existente
-
-``` sql
-ALTER TABLE example_table
-    MODIFY COLUMN
-    c String TTL d + INTERVAL 1 DAY;
-```
-
-Modificación de TTL de la columna
-
-``` sql
-ALTER TABLE example_table
-    MODIFY COLUMN
-    c String TTL d + INTERVAL 1 MONTH;
-```
-
-### Tabla TTL {#mergetree-table-ttl}
-
-La tabla puede tener una expresión para la eliminación de filas caducadas y varias expresiones para el movimiento automático de partes entre [discos o volúmenes](#table_engine-mergetree-multiple-volumes). Cuando las filas de la tabla caducan, ClickHouse elimina todas las filas correspondientes. Para la entidad de movimiento de piezas, todas las filas de una pieza deben cumplir los criterios de expresión de movimiento.
-
-``` sql
-TTL expr [DELETE|TO DISK 'aaa'|TO VOLUME 'bbb'], ...
-```
-
-El tipo de regla TTL puede seguir cada expresión TTL. Afecta a una acción que debe realizarse una vez que se satisface la expresión (alcanza la hora actual):
-
--   `DELETE` - Eliminar filas caducadas (acción predeterminada);
--   `TO DISK 'aaa'` - mover parte al disco `aaa`;
--   `TO VOLUME 'bbb'` - mover parte al disco `bbb`.
-
-Ejemplos:
-
-Creación de una tabla con TTL
-
-``` sql
-CREATE TABLE example_table
-(
-    d DateTime,
-    a Int
-)
-ENGINE = MergeTree
-PARTITION BY toYYYYMM(d)
-ORDER BY d
-TTL d + INTERVAL 1 MONTH [DELETE],
-    d + INTERVAL 1 WEEK TO VOLUME 'aaa',
-    d + INTERVAL 2 WEEK TO DISK 'bbb';
-```
-
-Modificación de TTL de la tabla
-
-``` sql
-ALTER TABLE example_table
-    MODIFY TTL d + INTERVAL 1 DAY;
-```
-
-**Eliminación de datos**
-
-Los datos con un TTL caducado se eliminan cuando ClickHouse fusiona partes de datos.
-
-Cuando ClickHouse ve que los datos han caducado, realiza una combinación fuera de programación. Para controlar la frecuencia de tales fusiones, puede establecer `merge_with_ttl_timeout`. Si el valor es demasiado bajo, realizará muchas fusiones fuera de horario que pueden consumir muchos recursos.
-
-Si realiza el `SELECT` consulta entre fusiones, puede obtener datos caducados. Para evitarlo, use el [OPTIMIZE](../../../sql-reference/statements/misc.md#misc_operations-optimize) consulta antes `SELECT`.
-
-## Uso de varios dispositivos de bloque para el almacenamiento de datos {#table_engine-mergetree-multiple-volumes}
-
-### Implantación {#introduction}
-
-`MergeTree` Los motores de tablas familiares pueden almacenar datos en múltiples dispositivos de bloque. Por ejemplo, puede ser útil cuando los datos de una determinada tabla se dividen implícitamente en “hot” y “cold”. Los datos más recientes se solicitan regularmente, pero solo requieren una pequeña cantidad de espacio. Por el contrario, los datos históricos de cola gorda se solicitan raramente. Si hay varios discos disponibles, el “hot” los datos pueden estar ubicados en discos rápidos (por ejemplo, SSD NVMe o en memoria), mientras que “cold” datos - en los relativamente lentos (por ejemplo, HDD).
-
-La parte de datos es la unidad móvil mínima para `MergeTree`-mesas de motor. Los datos que pertenecen a una parte se almacenan en un disco. Las partes de datos se pueden mover entre discos en segundo plano (según la configuración del usuario) así como por medio de la [ALTER](../../../sql-reference/statements/alter.md#alter_move-partition) consulta.
-

-
-En un ejemplo dado, el `hdd_in_order` la política implementa el [Ronda-robin](https://en.wikipedia.org/wiki/Round-robin_scheduling) enfoque. Por lo tanto, esta política define solo un volumen (`single`), las partes de datos se almacenan en todos sus discos en orden circular. Dicha política puede ser bastante útil si hay varios discos similares montados en el sistema, pero RAID no está configurado. Tenga en cuenta que cada unidad de disco individual no es confiable y es posible que desee compensarlo con un factor de replicación de 3 o más.
-
-Si hay diferentes tipos de discos disponibles en el sistema, `moving_from_ssd_to_hdd` política se puede utilizar en su lugar. Volumen `hot` consta de un disco SSD (`fast_ssd`), y el tamaño máximo de una pieza que se puede almacenar en este volumen es de 1 GB. Todas las piezas con el tamaño más grande que 1GB serán almacenadas directamente en `cold` volumen, que contiene un disco duro `disk1`.
-Además, una vez que el disco `fast_ssd` se llena en más del 80%, los datos se transferirán al `disk1` por un proceso en segundo plano.
-
-El orden de enumeración de volúmenes dentro de una directiva de almacenamiento es importante. Una vez que un volumen está sobrellenado, los datos se mueven al siguiente. El orden de la enumeración del disco también es importante porque los datos se almacenan en ellos por turnos.
-
-Al crear una tabla, se puede aplicarle una de las directivas de almacenamiento configuradas:
-
-``` sql
-CREATE TABLE table_with_non_default_policy (
-    EventDate Date,
-    OrderID UInt64,
-    BannerID UInt64,
-    SearchPhrase String
-) ENGINE = MergeTree
-ORDER BY (OrderID, BannerID)
-PARTITION BY toYYYYMM(EventDate)
-SETTINGS storage_policy = 'moving_from_ssd_to_hdd'
-```
-
-El `default` política de almacenamiento implica el uso de un solo volumen, que consiste en un solo disco dado en `<path>`. Una vez que se crea una tabla, no se puede cambiar su política de almacenamiento.
-
-### Detalles {#details}
-
-En el caso de `MergeTree` tablas, los datos están llegando al disco de diferentes maneras:
-
--   Como resultado de un inserto (`INSERT` consulta).
--   Durante las fusiones de fondo y [mutación](../../../sql-reference/statements/alter.md#alter-mutations).
--   Al descargar desde otra réplica.
--   Como resultado de la congelación de particiones [ALTER TABLE … FREEZE PARTITION](../../../sql-reference/statements/alter.md#alter_freeze-partition).
-
-En todos estos casos, excepto las mutaciones y la congelación de particiones, una pieza se almacena en un volumen y un disco de acuerdo con la política de almacenamiento dada:
-
-1.  El primer volumen (en el orden de definición) que tiene suficiente espacio en disco para almacenar una pieza (`unreserved_space > current_part_size`) y permite almacenar partes de un tamaño determinado (`max_data_part_size_bytes > current_part_size`) se elige.
-2.  Dentro de este volumen, se elige ese disco que sigue al que se utilizó para almacenar el fragmento de datos anterior y que tiene espacio libre más que el tamaño de la pieza (`unreserved_space - keep_free_space_bytes > current_part_size`).
-
-Bajo el capó, las mutaciones y la congelación de particiones hacen uso de [enlaces duros](https://en.wikipedia.org/wiki/Hard_link). Los enlaces duros entre diferentes discos no son compatibles, por lo tanto, en tales casos las partes resultantes se almacenan en los mismos discos que los iniciales.
-
-En el fondo, las partes se mueven entre volúmenes en función de la cantidad de espacio libre (`move_factor` parámetro) según el orden en que se declaran los volúmenes en el archivo de configuración.
-Los datos nunca se transfieren desde el último y al primero. Uno puede usar tablas del sistema [sistema.part_log](../../../operations/system-tables.md#system_tables-part-log) (campo `type = MOVE_PART`) y [sistema.parte](../../../operations/system-tables.md#system_tables-parts) (campo `path` y `disk`) para monitorear movimientos de fondo. Además, la información detallada se puede encontrar en los registros del servidor.
-
-El usuario puede forzar el movimiento de una pieza o una partición de un volumen a otro mediante la consulta [ALTER TABLE … MOVE PART\|PARTITION … TO VOLUME\|DISK …](../../../sql-reference/statements/alter.md#alter_move-partition), todas las restricciones para las operaciones en segundo plano se tienen en cuenta. La consulta inicia un movimiento por sí misma y no espera a que se completen las operaciones en segundo plano. El usuario recibirá un mensaje de error si no hay suficiente espacio libre disponible o si no se cumple alguna de las condiciones requeridas.
-
-Mover datos no interfiere con la replicación de datos. Por lo tanto, se pueden especificar diferentes directivas de almacenamiento para la misma tabla en diferentes réplicas.
-
-Después de la finalización de las fusiones y mutaciones de fondo, las partes viejas se eliminan solo después de un cierto período de tiempo (`old_parts_lifetime`).
-Durante este tiempo, no se mueven a otros volúmenes o discos. Por lo tanto, hasta que las partes finalmente se eliminen, aún se tienen en cuenta para la evaluación del espacio en disco ocupado.

-# ReplacingMergeTree {#replacingmergetree}
-
-El motor difiere de [Método de codificación de datos:](mergetree.md#table_engines-mergetree) en que elimina las entradas duplicadas con el mismo valor de clave principal (o más exactamente, con el mismo [clave de clasificación](mergetree.md) valor).
-
-La desduplicación de datos solo se produce durante una fusión. La fusión ocurre en segundo plano en un momento desconocido, por lo que no puede planificarla. Algunos de los datos pueden permanecer sin procesar. Aunque puede ejecutar una fusión no programada utilizando el `OPTIMIZE` consulta, no cuente con usarlo, porque el `OPTIMIZE` consulta leerá y escribirá una gran cantidad de datos.
-
-Así, `ReplacingMergeTree` es adecuado para borrar datos duplicados en segundo plano para ahorrar espacio, pero no garantiza la ausencia de duplicados.
-
-## Creación de una tabla {#creating-a-table}

-# Replicación de datos {#table_engines-replication}
-
-La replicación solo se admite para tablas de la familia MergeTree:
-
--   ReplicatedMergeTree
--   ReplicatedSummingMergeTree
--   ReplicatedReplacingMergeTree
--   ReplicatedAggregatingMergeTree
--   ReplicatedCollapsingMergeTree
--   ReplicatedVersionedCollapsingMergetree
--   ReplicatedGraphiteMergeTree
-
-La replicación funciona a nivel de una tabla individual, no de todo el servidor. Un servidor puede almacenar tablas replicadas y no replicadas al mismo tiempo.
-
-La replicación no depende de la fragmentación. Cada fragmento tiene su propia replicación independiente.
-
-Datos comprimidos para `INSERT` y `ALTER` se replica (para obtener más información, consulte la documentación para [ALTER](../../../sql-reference/statements/alter.md#query_language_queries_alter)).
-
-`CREATE`, `DROP`, `ATTACH`, `DETACH` y `RENAME` las consultas se ejecutan en un único servidor y no se replican:
-
--   El `CREATE TABLE` query crea una nueva tabla replicable en el servidor donde se ejecuta la consulta. Si esta tabla ya existe en otros servidores, agrega una nueva réplica.
--   El `DROP TABLE` query elimina la réplica ubicada en el servidor donde se ejecuta la consulta.
--   El `RENAME` query cambia el nombre de la tabla en una de las réplicas. En otras palabras, las tablas replicadas pueden tener diferentes nombres en diferentes réplicas.
-
-Uso de ClickHouse [Apache ZooKeeper](https://zookeeper.apache.org) para almacenar metainformación de réplicas. Utilice ZooKeeper versión 3.4.5 o posterior.
-
-Para utilizar la replicación, establezca los parámetros [Zookeeper](../../../operations/server-configuration-parameters/settings.md#server-settings_zookeeper) sección de configuración del servidor.
-
-!!! attention "Atención"
-    No descuides la configuración de seguridad. ClickHouse soporta el `digest` [Esquema de ACL](https://zookeeper.apache.org/doc/current/zookeeperProgrammers.html#sc_ZooKeeperAccessControl) del subsistema de seguridad ZooKeeper.
-
-Ejemplo de configuración de las direcciones del clúster ZooKeeper:
-
-``` xml
-<zookeeper>
-    <node index="1">
-        <host>example1</host>
-        <port>2181</port>
-    </node>
-    <node index="2">
-        <host>example2</host>
-        <port>2181</port>
-    </node>
-    <node index="3">
-        <host>example3</host>
-        <port>2181</port>
-    </node>
-</zookeeper>
-```
-
-Puede especificar cualquier clúster ZooKeeper existente y el sistema utilizará un directorio en él para sus propios datos (el directorio se especifica al crear una tabla replicable).
-
-Si ZooKeeper no está establecido en el archivo de configuración, no puede crear tablas replicadas y las tablas replicadas existentes serán de solo lectura.
-
-ZooKeeper no se utiliza en `SELECT` consultas porque la replicación no afecta al rendimiento de `SELECT` y las consultas se ejecutan tan rápido como lo hacen para las tablas no replicadas. Al consultar tablas replicadas distribuidas, el comportamiento de ClickHouse se controla mediante la configuración [max_replica_delay_for_distributed_queries](../../../operations/settings/settings.md#settings-max_replica_delay_for_distributed_queries) y [fallback_to_stale_replicas_for_distributed_queries](../../../operations/settings/settings.md#settings-fallback_to_stale_replicas_for_distributed_queries).
-
-Para cada `INSERT` consulta, aproximadamente diez entradas se agregan a ZooKeeper a través de varias transacciones. (Para ser más precisos, esto es para cada bloque de datos insertado; una consulta INSERT contiene un bloque o un bloque por `max_insert_block_size = 1048576` filas.) Esto conduce a latencias ligeramente más largas para `INSERT` en comparación con las tablas no replicadas. Pero si sigue las recomendaciones para insertar datos en lotes de no más de uno `INSERT` por segundo, no crea ningún problema. Todo el clúster ClickHouse utilizado para coordinar un clúster ZooKeeper tiene un total de varios cientos `INSERTs` por segundo. El rendimiento en las inserciones de datos (el número de filas por segundo) es tan alto como para los datos no replicados.
-
-Para clústeres muy grandes, puede usar diferentes clústeres de ZooKeeper para diferentes fragmentos. Sin embargo, esto no ha demostrado ser necesario en el Yandex.Clúster Metrica (aproximadamente 300 servidores).
-
-La replicación es asíncrona y multi-master. `INSERT` consultas (así como `ALTER`) se puede enviar a cualquier servidor disponible. Los datos se insertan en el servidor donde se ejecuta la consulta y, a continuación, se copian a los demás servidores. Debido a que es asincrónico, los datos insertados recientemente aparecen en las otras réplicas con cierta latencia. Si parte de las réplicas no está disponible, los datos se escriben cuando estén disponibles. Si hay una réplica disponible, la latencia es la cantidad de tiempo que tarda en transferir el bloque de datos comprimidos a través de la red.
-
-De forma predeterminada, una consulta INSERT espera la confirmación de la escritura de los datos de una sola réplica. Si los datos fue correctamente escrito a sólo una réplica y el servidor con esta réplica deja de existir, los datos almacenados se perderán. Para habilitar la confirmación de las escrituras de datos de varias réplicas, utilice `insert_quorum` opcion.
-
-Cada bloque de datos se escribe atómicamente. La consulta INSERT se divide en bloques hasta `max_insert_block_size = 1048576` filas. En otras palabras, si el `INSERT` consulta tiene menos de 1048576 filas, se hace atómicamente.
-
-Los bloques de datos se deduplican. Para varias escrituras del mismo bloque de datos (bloques de datos del mismo tamaño que contienen las mismas filas en el mismo orden), el bloque solo se escribe una vez. La razón de esto es en caso de fallas de red cuando la aplicación cliente no sabe si los datos se escribieron en la base de datos, por lo que `INSERT` consulta simplemente se puede repetir. No importa a qué réplica se enviaron los INSERT con datos idénticos. `INSERTs` son idempotentes. Los parámetros de desduplicación son controlados por [merge_tree](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-merge_tree) configuración del servidor.
-
-Durante la replicación, sólo los datos de origen que se van a insertar se transfieren a través de la red. La transformación de datos adicional (fusión) se coordina y se realiza en todas las réplicas de la misma manera. Esto minimiza el uso de la red, lo que significa que la replicación funciona bien cuando las réplicas residen en centros de datos diferentes. (Tenga en cuenta que la duplicación de datos en diferentes centros de datos es el objetivo principal de la replicación.)
-
-Puede tener cualquier número de réplicas de los mismos datos. El Yandex.Metrica utiliza doble replicación en producción. Cada servidor utiliza RAID-5 o RAID-6, y RAID-10 en algunos casos. Esta es una solución relativamente confiable y conveniente.
-
-El sistema supervisa la sincronicidad de los datos en las réplicas y puede recuperarse después de un fallo. La conmutación por error es automática (para pequeñas diferencias en los datos) o semiautomática (cuando los datos difieren demasiado, lo que puede indicar un error de configuración).
-
-## Creación de tablas replicadas {#creating-replicated-tables}
-
-El `Replicated` prefijo se agrega al nombre del motor de tabla. Por ejemplo:`ReplicatedMergeTree`.
-
-**Replicated\*MergeTree parámetros**
-
--   `zoo_path` — The path to the table in ZooKeeper.
--   `replica_name` — The replica name in ZooKeeper.
-
-Ejemplo:
-
-``` sql
-CREATE TABLE table_name
-(
-    EventDate DateTime,
-    CounterID UInt32,
-    UserID UInt32
-) ENGINE = ReplicatedMergeTree('/clickhouse/tables/{layer}-{shard}/table_name', '{replica}')
-PARTITION BY toYYYYMM(EventDate)
-ORDER BY (CounterID, EventDate, intHash32(UserID))
-SAMPLE BY intHash32(UserID)
-```
-
-<details markdown="1">
-
-<summary>Ejemplo en sintaxis obsoleta</summary>
-
-``` sql
-CREATE TABLE table_name
-(
-    EventDate DateTime,
-    CounterID UInt32,
-    UserID UInt32
-) ENGINE = ReplicatedMergeTree('/clickhouse/tables/{layer}-{shard}/table_name', '{replica}', EventDate, intHash32(UserID), (CounterID, EventDate, intHash32(UserID), EventTime), 8192)
-```
-
-</details>
-
-Como muestra el ejemplo, estos parámetros pueden contener sustituciones entre llaves. Los valores sustituidos se toman de la ‘macros’ sección del archivo de configuración. Ejemplo:
-
-``` xml
-<macros>
-    <layer>05</layer>
-    <shard>02</shard>
-    <replica>example05-02-1.yandex.ru</replica>
-</macros>
-```
-
-La ruta de acceso a la tabla en ZooKeeper debe ser única para cada tabla replicada. Las tablas en diferentes fragmentos deben tener rutas diferentes.
-En este caso, la ruta consta de las siguientes partes:
-
-`/clickhouse/tables/` es el prefijo común. Recomendamos usar exactamente este.
-
-`{layer}-{shard}` es el identificador de fragmento. En este ejemplo consta de dos partes, ya que el Yandex.Metrica clúster utiliza sharding de dos niveles. Para la mayoría de las tareas, puede dejar solo la sustitución {shard}, que se expandirá al identificador de fragmento.
-
-`table_name` es el nombre del nodo de la tabla en ZooKeeper. Es una buena idea hacerlo igual que el nombre de la tabla. Se define explícitamente, porque a diferencia del nombre de la tabla, no cambia después de una consulta RENAME.
-*HINT*: podría agregar un nombre de base de datos delante de `table_name` También. Nivel de Cifrado WEP `db_name.table_name`
-
-El nombre de réplica identifica diferentes réplicas de la misma tabla. Puede usar el nombre del servidor para esto, como en el ejemplo. El nombre solo tiene que ser único dentro de cada fragmento.
-
-Puede definir los parámetros explícitamente en lugar de utilizar sustituciones. Esto podría ser conveniente para probar y para configurar clústeres pequeños. Sin embargo, no puede usar consultas DDL distribuidas (`ON CLUSTER` en este caso.
-
-Cuando se trabaja con clústeres grandes, se recomienda utilizar sustituciones porque reducen la probabilidad de error.
-
-Ejecute el `CREATE TABLE` consulta en cada réplica. Esta consulta crea una nueva tabla replicada o agrega una nueva réplica a una existente.
-
-Si agrega una nueva réplica después de que la tabla ya contenga algunos datos en otras réplicas, los datos se copiarán de las otras réplicas a la nueva después de ejecutar la consulta. En otras palabras, la nueva réplica se sincroniza con las demás.
-
-Para eliminar una réplica, ejecute `DROP TABLE`. However, only one replica is deleted – the one that resides on the server where you run the query.
-
-## Recuperación después de fallos {#recovery-after-failures}
-
-Si ZooKeeper no está disponible cuando se inicia un servidor, las tablas replicadas cambian al modo de solo lectura. El sistema intenta conectarse periódicamente a ZooKeeper.
-
-Si ZooKeeper no está disponible durante un `INSERT`, o se produce un error al interactuar con ZooKeeper, se produce una excepción.
-
-Después de conectarse a ZooKeeper, el sistema comprueba si el conjunto de datos en el sistema de archivos local coincide con el conjunto de datos esperado (ZooKeeper almacena esta información). Si hay incoherencias menores, el sistema las resuelve sincronizando datos con las réplicas.
-
-Si el sistema detecta partes de datos rotas (con un tamaño incorrecto de archivos) o partes no reconocidas (partes escritas en el sistema de archivos pero no grabadas en ZooKeeper), las mueve al `detached` subdirectorio (no se eliminan). Las piezas que faltan se copian de las réplicas.
-
-Tenga en cuenta que ClickHouse no realiza ninguna acción destructiva, como eliminar automáticamente una gran cantidad de datos.
-
-Cuando el servidor se inicia (o establece una nueva sesión con ZooKeeper), solo verifica la cantidad y el tamaño de todos los archivos. Si los tamaños de los archivos coinciden pero los bytes se han cambiado en algún punto intermedio, esto no se detecta inmediatamente, sino solo cuando se intenta leer los datos `SELECT` consulta. La consulta produce una excepción sobre una suma de comprobación no coincidente o el tamaño de un bloque comprimido. En este caso, las partes de datos se agregan a la cola de verificación y se copian de las réplicas si es necesario.
-
-Si el conjunto local de datos difiere demasiado del esperado, se activa un mecanismo de seguridad. El servidor ingresa esto en el registro y se niega a iniciarse. La razón de esto es que este caso puede indicar un error de configuración, como si una réplica en un fragmento se configurara accidentalmente como una réplica en un fragmento diferente. Sin embargo, los umbrales para este mecanismo se establecen bastante bajos, y esta situación puede ocurrir durante la recuperación de falla normal. En este caso, los datos se restauran semiautomáticamente, mediante “pushing a button”.
-
-Para iniciar la recuperación, cree el nodo `/path_to_table/replica_name/flags/force_restore_data` en ZooKeeper con cualquier contenido, o ejecute el comando para restaurar todas las tablas replicadas:
-
-``` bash
-sudo -u clickhouse touch /var/lib/clickhouse/flags/force_restore_data
-```
-
-A continuación, reinicie el servidor. Al iniciar, el servidor elimina estos indicadores e inicia la recuperación.
-
-## Recuperación después de la pérdida completa de datos {#recovery-after-complete-data-loss}
-
-Si todos los datos y metadatos desaparecieron de uno de los servidores, siga estos pasos para la recuperación:
-
-1.  Instale ClickHouse en el servidor. Defina correctamente las sustituciones en el archivo de configuración que contiene el identificador de fragmento y las réplicas, si las usa.
-2.  Si tenía tablas no duplicadas que deben duplicarse manualmente en los servidores, copie sus datos desde una réplica (en el directorio `/var/lib/clickhouse/data/db_name/table_name/`).
-3.  Copiar definiciones de tablas ubicadas en `/var/lib/clickhouse/metadata/` de una réplica. Si un identificador de fragmento o réplica se define explícitamente en las definiciones de tabla, corríjalo para que corresponda a esta réplica. (Como alternativa, inicie el servidor y `ATTACH TABLE` consultas que deberían haber estado en el .sql archivos en `/var/lib/clickhouse/metadata/`.)
-4.  Para iniciar la recuperación, cree el nodo ZooKeeper `/path_to_table/replica_name/flags/force_restore_data` con cualquier contenido o ejecute el comando para restaurar todas las tablas replicadas: `sudo -u clickhouse touch /var/lib/clickhouse/flags/force_restore_data`
-
-Luego inicie el servidor (reinicie, si ya se está ejecutando). Los datos se descargarán de las réplicas.
-
-Una opción de recuperación alternativa es eliminar información sobre la réplica perdida de ZooKeeper (`/path_to_table/replica_name`), luego vuelva a crear la réplica como se describe en “[Creación de tablas replicadas](#creating-replicated-tables)”.
-
-No hay restricción en el ancho de banda de la red durante la recuperación. Tenga esto en cuenta si está restaurando muchas réplicas a la vez.
-
-## La conversión de MergeTree a ReplicatedMergeTree {#converting-from-mergetree-to-replicatedmergetree}
-
-Usamos el término `MergeTree` para referirse a todos los motores de mesa en el `MergeTree family`, lo mismo que para `ReplicatedMergeTree`.
-
-Si usted tenía un `MergeTree` tabla replicada manualmente, puede convertirla en una tabla replicada. Es posible que tenga que hacer esto si ya ha recopilado una gran cantidad de datos `MergeTree` y ahora desea habilitar la replicación.

-Si los datos difieren en varias réplicas, primero sincronícelos o elimínelos en todas las réplicas, excepto en una.
-
-Cambie el nombre de la tabla MergeTree existente y, a continuación, cree un `ReplicatedMergeTree` mesa con el antiguo nombre.
-Mueva los datos de la tabla antigua a la `detached` subdirectorio dentro del directorio con los nuevos datos de la tabla (`/var/lib/clickhouse/data/db_name/table_name/`).
-Luego ejecuta `ALTER TABLE ATTACH PARTITION` en una de las réplicas para agregar estas partes de datos al conjunto de trabajo.
-
-## La conversión de ReplicatedMergeTree a MergeTree {#converting-from-replicatedmergetree-to-mergetree}
-
-Cree una tabla MergeTree con un nombre diferente. Mueva todos los datos del directorio con el `ReplicatedMergeTree` datos de la tabla al directorio de datos de la nueva tabla. A continuación, elimine el `ReplicatedMergeTree` y reinicie el servidor.
-
-Si desea deshacerse de un `ReplicatedMergeTree` sin iniciar el servidor:
-
--   Eliminar el correspondiente `.sql` archivo en el directorio de metadatos (`/var/lib/clickhouse/metadata/`).
--   Eliminar la ruta correspondiente en ZooKeeper (`/path_to_table/replica_name`).
-
-Después de esto, puede iniciar el servidor, crear un `MergeTree` tabla, mueva los datos a su directorio y, a continuación, reinicie el servidor.

-# SummingMergeTree {#summingmergetree}
-
-El motor hereda de [Método de codificación de datos:](mergetree.md#table_engines-mergetree). La diferencia es que al fusionar partes de datos para `SummingMergeTree` ClickHouse reemplaza todas las filas con la misma clave primaria (o más exactamente, con la misma [clave de clasificación](mergetree.md)) con una fila que contiene valores resumidos para las columnas con el tipo de datos numérico. Si la clave de ordenación está compuesta de manera que un solo valor de clave corresponde a un gran número de filas, esto reduce significativamente el volumen de almacenamiento y acelera la selección de datos.
-
-Recomendamos usar el motor junto con `MergeTree`. Almacenar datos completos en `MergeTree` mesa, y el uso `SummingMergeTree` para el almacenamiento de datos agregados, por ejemplo, al preparar informes. Tal enfoque evitará que pierda datos valiosos debido a una clave primaria compuesta incorrectamente.
-
-## Creación de una tabla {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = SummingMergeTree([columns])
-[PARTITION BY expr]
-[ORDER BY expr]
-[SAMPLE BY expr]
-[SETTINGS name=value, ...]
-```
-
-Para obtener una descripción de los parámetros de solicitud, consulte [descripción de la solicitud](../../../sql-reference/statements/create.md).
-
-**Parámetros de SummingMergeTree**
-
--   `columns` - una tupla con los nombres de las columnas donde se resumirán los valores. Parámetro opcional.
-    Las columnas deben ser de tipo numérico y no deben estar en la clave principal.
-
-    Si `columns` no especificado, ClickHouse resume los valores de todas las columnas con un tipo de datos numérico que no están en la clave principal.
-
-**Cláusulas de consulta**
-
-Al crear un `SummingMergeTree` mesa de la misma [clausula](mergetree.md) se requieren, como al crear un `MergeTree` tabla.
-
-<details markdown="1">
-
-<summary>Método obsoleto para crear una tabla</summary>
-
-!!! attention "Atención"
-    No use este método en proyectos nuevos y, si es posible, cambie los proyectos antiguos al método descrito anteriormente.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE [=] SummingMergeTree(date-column [, sampling_expression], (primary, key), index_granularity, [columns])
-```
-
-Todos los parámetros excepto `columns` el mismo significado que en `MergeTree`.
-
--   `columns` — tuple with names of columns values of which will be summarized. Optional parameter. For a description, see the text above.
-
-</details>
-
-## Ejemplo de uso {#usage-example}
-
-Considere la siguiente tabla:
-
-``` sql
-CREATE TABLE summtt
-(
-    key UInt32,
-    value UInt32
-)
-ENGINE = SummingMergeTree()
-ORDER BY key
-```
-
-Insertar datos:
-
-``` sql
-INSERT INTO summtt Values(1,1),(1,2),(2,1)
-```
-
-ClickHouse puede sumar todas las filas no completamente ([ver abajo](#data-processing)), entonces usamos una función agregada `sum` y `GROUP BY` cláusula en la consulta.
-
-``` sql
-SELECT key, sum(value) FROM summtt GROUP BY key
-```
-
-``` text
-┌─key─┬─sum(value)─┐
-│   2 │          1 │
-│   1 │          3 │
-└─────┴────────────┘
-```
-
-## Procesamiento de datos {#data-processing}
-
-Cuando los datos se insertan en una tabla, se guardan tal cual. ClickHouse combina las partes insertadas de los datos periódicamente y esto es cuando las filas con la misma clave principal se suman y se reemplazan con una para cada parte resultante de los datos.
-
-ClickHouse can merge the data parts so that different resulting parts of data cat consist rows with the same primary key, i.e. the summation will be incomplete. Therefore (`SELECT`) una función agregada [resumir()](../../../sql-reference/aggregate-functions/reference.md#agg_function-sum) y `GROUP BY` cláusula se debe utilizar en una consulta como se describe en el ejemplo anterior.
-
-### Reglas comunes para la suma {#common-rules-for-summation}
-
-Se resumen los valores de las columnas con el tipo de datos numérico. El conjunto de columnas está definido por el parámetro `columns`.
-
-Si los valores eran 0 en todas las columnas para la suma, se elimina la fila.
-
-Si la columna no está en la clave principal y no se resume, se selecciona un valor arbitrario entre los existentes.
-
-Los valores no se resumen para las columnas de la clave principal.
-
-### La suma en las columnas de función agregada {#the-summation-in-the-aggregatefunction-columns}
-
-Para columnas de [Tipo AggregateFunction](../../../sql-reference/data-types/aggregatefunction.md) ClickHouse se comporta como [AgregaciónMergeTree](aggregatingmergetree.md) agregación del motor según la función.
-
-### Estructuras anidadas {#nested-structures}
-
-La tabla puede tener estructuras de datos anidadas que se procesan de una manera especial.
-
-Si el nombre de una tabla anidada termina con `Map` y contiene al menos dos columnas que cumplen los siguientes criterios:
-
--   la primera columna es numérica `(*Int*, Date, DateTime)` o una cadena `(String, FixedString)`, vamos a llamarlo `key`,
--   las otras columnas son aritméticas `(*Int*, Float32/64)`, vamos a llamarlo `(values...)`,
-
-entonces esta tabla anidada se interpreta como una asignación de `key => (values...)`, y al fusionar sus filas, los elementos de dos conjuntos de datos se fusionan por `key` con una suma de los correspondientes `(values...)`.
-
-Ejemplos:
-
-``` text
-[(1, 100)] + [(2, 150)] -> [(1, 100), (2, 150)]
-[(1, 100)] + [(1, 150)] -> [(1, 250)]
-[(1, 100)] + [(1, 150), (2, 150)] -> [(1, 250), (2, 150)]
-[(1, 100), (2, 150)] + [(1, -100)] -> [(2, 150)]
-```
-
-Al solicitar datos, utilice el [sumMap(clave, valor)](../../../sql-reference/aggregate-functions/reference.md) función para la agregación de `Map`.
-
-Para la estructura de datos anidados, no necesita especificar sus columnas en la tupla de columnas para la suma.

-## Derrumbar {#table_engines_versionedcollapsingmergetree}
-
-### Datos {#data}
-
-Considere una situación en la que necesite guardar datos que cambien continuamente para algún objeto. Es razonable tener una fila para un objeto y actualizar la fila siempre que haya cambios. Sin embargo, la operación de actualización es costosa y lenta para un DBMS porque requiere volver a escribir los datos en el almacenamiento. La actualización no es aceptable si necesita escribir datos rápidamente, pero puede escribir los cambios en un objeto secuencialmente de la siguiente manera.
-
-Utilice el `Sign` columna al escribir la fila. Si `Sign = 1` significa que la fila es un estado de un objeto (llamémoslo el “state” fila). Si `Sign = -1` indica la cancelación del estado de un objeto con los mismos atributos (llamémoslo el “cancel” fila). También use el `Version` columna, que debe identificar cada estado de un objeto con un número separado.
-
-Por ejemplo, queremos calcular cuántas páginas visitaron los usuarios en algún sitio y cuánto tiempo estuvieron allí. En algún momento escribimos la siguiente fila con el estado de la actividad del usuario:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐
-│ 4324182021466249494 │         5 │      146 │    1 │       1 |
-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-En algún momento después registramos el cambio de actividad del usuario y lo escribimos con las siguientes dos filas.
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │       1 |
-│ 4324182021466249494 │         6 │      185 │    1 │       2 |
-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-La primera fila cancela el estado anterior del objeto (usuario). Debe copiar todos los campos del estado cancelado excepto `Sign`.
-
-La segunda fila contiene el estado actual.
-
-Debido a que solo necesitamos el último estado de actividad del usuario, las filas
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐
-│ 4324182021466249494 │         5 │      146 │    1 │       1 |
-│ 4324182021466249494 │         5 │      146 │   -1 │       1 |
-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-se puede eliminar, colapsando el estado no válido (antiguo) del objeto. `VersionedCollapsingMergeTree` hace esto mientras fusiona las partes de datos.
-
-Para averiguar por qué necesitamos dos filas para cada cambio, vea [Algoritmo](#table_engines-versionedcollapsingmergetree-algorithm).
-
-**Notas sobre el uso**
-
-1.  El programa que escribe los datos debe recordar el estado de un objeto para cancelarlo. El “cancel” cadena debe ser una copia de la “state” con lo opuesto `Sign`. Esto aumenta el tamaño inicial de almacenamiento, pero permite escribir los datos rápidamente.
-2.  Las matrices de largo crecimiento en columnas reducen la eficiencia del motor debido a la carga para escribir. Cuanto más sencillos sean los datos, mejor será la eficiencia.
-3.  `SELECT` Los resultados dependen en gran medida de la coherencia del historial de cambios de objetos. Sea preciso al preparar los datos para insertarlos. Puede obtener resultados impredecibles con datos incoherentes, como valores negativos para métricas no negativas, como la profundidad de la sesión.
-
-### Algoritmo {#table_engines-versionedcollapsingmergetree-algorithm}
-
-Cuando ClickHouse combina partes de datos, elimina cada par de filas que tienen la misma clave principal y versión y diferentes `Sign`. El orden de las filas no importa.
-
-Cuando ClickHouse inserta datos, ordena filas por la clave principal. Si el `Version` la columna no está en la clave principal, ClickHouse la agrega a la clave principal implícitamente como el último campo y la usa para ordenar.
-
-## Selección de datos {#selecting-data}
-
-ClickHouse no garantiza que todas las filas con la misma clave principal estén en la misma parte de datos resultante o incluso en el mismo servidor físico. Esto es cierto tanto para escribir los datos como para la posterior fusión de las partes de datos. Además, ClickHouse procesa `SELECT` consultas con múltiples subprocesos, y no puede predecir el orden de las filas en el resultado. Esto significa que la agregación es necesaria si hay una necesidad de obtener completamente “collapsed” datos de un `VersionedCollapsingMergeTree` tabla.
-
-Para finalizar el colapso, escriba una consulta con un `GROUP BY` cláusula y funciones agregadas que representan el signo. Por ejemplo, para calcular la cantidad, use `sum(Sign)` en lugar de `count()`. Para calcular la suma de algo, use `sum(Sign * x)` en lugar de `sum(x)` y agregar `HAVING sum(Sign) > 0`.
-
-Los agregados `count`, `sum` y `avg` se puede calcular de esta manera. El agregado `uniq` se puede calcular si un objeto tiene al menos un estado no colapsado. Los agregados `min` y `max` no se puede calcular porque `VersionedCollapsingMergeTree` no guarda el historial de valores de estados colapsados.
-
-Si necesita extraer los datos con “collapsing” pero sin agregación (por ejemplo, para verificar si hay filas presentes cuyos valores más nuevos coinciden con ciertas condiciones), puede usar el `FINAL` modificador para el `FROM` clausula. Este enfoque es ineficiente y no debe usarse con tablas grandes.

-Creación de la tabla:
-
-``` sql
-CREATE TABLE UAct
-(
-    UserID UInt64,
-    PageViews UInt8,
-    Duration UInt8,
-    Sign Int8,
-    Version UInt8
-)
-ENGINE = VersionedCollapsingMergeTree(Sign, Version)
-ORDER BY UserID
-```
-
-Insertar los datos:
-
-``` sql
-INSERT INTO UAct VALUES (4324182021466249494, 5, 146, 1, 1)
-```
-

-```
-
-Usamos dos `INSERT` consultas para crear dos partes de datos diferentes. Si insertamos los datos con una sola consulta, ClickHouse crea una parte de datos y nunca realizará ninguna fusión.
-
-Obtener los datos:
-
-``` sql
-SELECT * FROM UAct
-```
-
-``` text

-
-¿Qué vemos aquí y dónde están las partes colapsadas?
-Creamos dos partes de datos usando dos `INSERT` consulta. El `SELECT` la consulta se realizó en dos subprocesos, y el resultado es un orden aleatorio de filas.
-No se produjo el colapso porque las partes de datos aún no se han fusionado. ClickHouse fusiona partes de datos en un punto desconocido en el tiempo que no podemos predecir.
-
-Es por eso que necesitamos agregación:
-
-``` sql
-SELECT
-    UserID,
-    sum(PageViews * Sign) AS PageViews,
-    sum(Duration * Sign) AS Duration,
-    Version
-FROM UAct
-GROUP BY UserID, Version
-HAVING sum(Sign) > 0
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Version─┐

-└─────────────────────┴───────────┴──────────┴─────────┘
-```
-
-Si no necesitamos agregación y queremos forzar el colapso, podemos usar el `FINAL` modificador para el `FROM` clausula.
-
-``` sql
-SELECT * FROM UAct FINAL
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐

-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-Esta es una forma muy ineficiente de seleccionar datos. No lo use para mesas grandes.

-# Búfer {#buffer}
-
-Almacena los datos para escribir en la memoria RAM, enjuagándolos periódicamente a otra tabla. Durante la operación de lectura, los datos se leen desde el búfer y la otra tabla simultáneamente.
-
-``` sql
-Buffer(database, table, num_layers, min_time, max_time, min_rows, max_rows, min_bytes, max_bytes)
-```
-
-Parámetros del motor:
-
--   `database` – Database name. Instead of the database name, you can use a constant expression that returns a string.
--   `table` – Table to flush data to.
--   `num_layers` – Parallelism layer. Physically, the table will be represented as `num_layers` de búferes independientes. Valor recomendado: 16.
--   `min_time`, `max_time`, `min_rows`, `max_rows`, `min_bytes`, y `max_bytes` – Conditions for flushing data from the buffer.
-
-Los datos se vacían del búfer y se escriben en la tabla de destino si `min*` condiciones o al menos una `max*` condición se cumplen.
-
--   `min_time`, `max_time` – Condition for the time in seconds from the moment of the first write to the buffer.
--   `min_rows`, `max_rows` – Condition for the number of rows in the buffer.
--   `min_bytes`, `max_bytes` – Condition for the number of bytes in the buffer.
-
-Durante la operación de escritura, los datos se insertan en un `num_layers` número de búferes aleatorios. O bien, si la parte de datos para insertar es lo suficientemente grande (mayor que `max_rows` o `max_bytes`), se escribe directamente en la tabla de destino, omitiendo el búfer.
-
-Las condiciones para el lavado de los datos se calculan por separado para cada uno de los `num_layers` búfer. Por ejemplo, si `num_layers = 16` y `max_bytes = 100000000`, el consumo máximo de RAM es de 1.6 GB.
-
-Ejemplo:
-
-``` sql
-CREATE TABLE merge.hits_buffer AS merge.hits ENGINE = Buffer(merge, hits, 16, 10, 100, 10000, 1000000, 10000000, 100000000)
-```
-
-Creación de un ‘merge.hits_buffer’ mesa con la misma estructura que ‘merge.hits’ y usando el motor Buffer. Al escribir en esta tabla, los datos se almacenan en la memoria RAM y ‘merge.hits’ tabla. Se crean 16 búferes. Los datos de cada uno de ellos se vacían si han pasado 100 segundos o se han escrito un millón de filas o se han escrito 100 MB de datos; o si simultáneamente han pasado 10 segundos y se han escrito 10.000 filas y 10 MB de datos. Por ejemplo, si solo se ha escrito una fila, después de 100 segundos se vaciará, pase lo que pase. Pero si se han escrito muchas filas, los datos se vaciarán antes.
-
-Cuando se detiene el servidor, con DROP TABLE o DETACH TABLE, los datos del búfer también se vacían a la tabla de destino.
-
-Puede establecer cadenas vacías entre comillas simples para la base de datos y el nombre de la tabla. Esto indica la ausencia de una tabla de destino. En este caso, cuando se alcanzan las condiciones de descarga de datos, el búfer simplemente se borra. Esto puede ser útil para mantener una ventana de datos en la memoria.
-
-Al leer desde una tabla de búfer, los datos se procesan tanto desde el búfer como desde la tabla de destino (si hay uno).
-Tenga en cuenta que las tablas Buffer no admiten un índice. En otras palabras, los datos del búfer se analizan por completo, lo que puede ser lento para los búferes grandes. (Para los datos de una tabla subordinada, se utilizará el índice que admite.)
-
-Si el conjunto de columnas de la tabla Buffer no coincide con el conjunto de columnas de una tabla subordinada, se inserta un subconjunto de columnas que existen en ambas tablas.
-
-Si los tipos no coinciden con una de las columnas de la tabla Búfer y una tabla subordinada, se escribe un mensaje de error en el registro del servidor y se borra el búfer.
-Lo mismo sucede si la tabla subordinada no existe cuando se vacía el búfer.
-
-Si necesita ejecutar ALTER para una tabla subordinada y la tabla de búfer, se recomienda eliminar primero la tabla de búfer, ejecutar ALTER para la tabla subordinada y, a continuación, crear la tabla de búfer de nuevo.
-
-Si el servidor se reinicia de forma anormal, se pierden los datos del búfer.
-
-FINAL y SAMPLE no funcionan correctamente para las tablas Buffer. Estas condiciones se pasan a la tabla de destino, pero no se utilizan para procesar datos en el búfer. Si se requieren estas características, recomendamos usar solo la tabla Buffer para escribir, mientras lee desde la tabla de destino.
-
-Al agregar datos a un búfer, uno de los búferes está bloqueado. Esto provoca retrasos si se realiza una operación de lectura simultáneamente desde la tabla.
-
-Los datos que se insertan en una tabla de búfer pueden terminar en la tabla subordinada en un orden diferente y en bloques diferentes. Debido a esto, una tabla Buffer es difícil de usar para escribir en un CollapsingMergeTree correctamente. Para evitar problemas, puede establecer ‘num_layers’ a 1.
-
-Si se replica la tabla de destino, se pierden algunas características esperadas de las tablas replicadas al escribir en una tabla de búfer. Los cambios aleatorios en el orden de las filas y los tamaños de las partes de datos hacen que la desduplicación de datos deje de funcionar, lo que significa que no es posible tener un ‘exactly once’ escribir en tablas replicadas.
-
-Debido a estas desventajas, solo podemos recomendar el uso de una tabla Buffer en casos raros.
-
-Una tabla de búfer se usa cuando se reciben demasiados INSERT de un gran número de servidores durante una unidad de tiempo y los datos no se pueden almacenar en búfer antes de la inserción, lo que significa que los INSERT no pueden ejecutarse lo suficientemente rápido.
-
-Tenga en cuenta que no tiene sentido insertar datos una fila a la vez, incluso para las tablas de búfer. Esto solo producirá una velocidad de unos pocos miles de filas por segundo, mientras que la inserción de bloques de datos más grandes puede producir más de un millón de filas por segundo (consulte la sección “Performance”).

-# Diccionario {#dictionary}
-
-El `Dictionary` el motor muestra el [diccionario](../../../sql-reference/dictionaries/external-dictionaries/external-dicts.md) datos como una tabla ClickHouse.
-
-Como ejemplo, considere un diccionario de `products` con la siguiente configuración:
-
-``` xml
-<dictionaries>
-<dictionary>
-        <name>products</name>
-        <source>

-
-Puede usar el [dictGet\*](../../../sql-reference/functions/ext-dict-functions.md#ext_dict_functions) función para obtener los datos del diccionario en este formato.
-
-Esta vista no es útil cuando necesita obtener datos sin procesar o cuando `JOIN` operación. Para estos casos, puede usar el `Dictionary` motor, que muestra los datos del diccionario en una tabla.
-
-Sintaxis:
-
-``` sql
-CREATE TABLE %table_name% (%fields%) engine = Dictionary(%dictionary_name%)`
-```
-
-Ejemplo de uso:
-
-``` sql
-create table products (product_id UInt64, title String) Engine = Dictionary(products);
-```
-
-      Ok
-
-Echa un vistazo a lo que hay en la mesa.
-
-``` sql
-select * from products limit 1;

-# Distribuido {#distributed}
-
-**Las tablas con motor distribuido no almacenan ningún dato por sí mismas**, pero permite el procesamiento de consultas distribuidas en varios servidores.
-La lectura se paralela automáticamente. Durante una lectura, se utilizan los índices de tabla en servidores remotos, si los hay.
-
-El motor distribuido acepta parámetros:
-
--   el nombre del clúster en el archivo de configuración del servidor
-
--   el nombre de una base de datos remota
-
--   el nombre de una tabla remota
-
--   (opcionalmente) clave de fragmentación
-
--   nombre de política (opcionalmente), se usará para almacenar archivos temporales para el envío asíncrono
-

-
-    -   `insert_distributed_sync` configuración
-    -   [Método de codificación de datos:](../mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes) para los ejemplos
-
-Ejemplo:
-
-``` sql
-Distributed(logs, default, hits[, sharding_key[, policy_name]])
-```
-
-Los datos se leerán desde todos los servidores ‘logs’ clúster, desde el valor predeterminado.tabla de éxitos ubicada en cada servidor del clúster.
-Los datos no solo se leen sino que se procesan parcialmente en los servidores remotos (en la medida en que esto sea posible).
-Por ejemplo, para una consulta con GROUP BY, los datos se agregarán en servidores remotos y los estados intermedios de las funciones agregadas se enviarán al servidor solicitante. Luego, los datos se agregarán más.
-
-En lugar del nombre de la base de datos, puede usar una expresión constante que devuelva una cadena. Por ejemplo: currentDatabase().
-
-logs – The cluster name in the server's config file.
-
-Los clústeres se establecen así:
-
-``` xml
-<remote_servers>
-    <logs>
-        <shard>
-            <!-- Optional. Shard weight when writing data. Default: 1. -->
-            <weight>1</weight>
-            <!-- Optional. Whether to write data to just one of the replicas. Default: false (write data to all replicas). -->
-            <internal_replication>false</internal_replication>
-            <replica>
-                <host>example01-01-1</host>
-                <port>9000</port>
-            </replica>
-            <replica>
-                <host>example01-01-2</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-        <shard>
-            <weight>2</weight>
-            <internal_replication>false</internal_replication>
-            <replica>
-                <host>example01-02-1</host>
-                <port>9000</port>
-            </replica>
-            <replica>
-                <host>example01-02-2</host>
-                <secure>1</secure>
-                <port>9440</port>
-            </replica>
-        </shard>
-    </logs>
-</remote_servers>
-```
-
-Aquí se define un clúster con el nombre ‘logs’ que consta de dos fragmentos, cada uno de los cuales contiene dos réplicas.
-Los fragmentos se refieren a los servidores que contienen diferentes partes de los datos (para leer todos los datos, debe acceder a todos los fragmentos).
-Las réplicas están duplicando servidores (para leer todos los datos, puede acceder a los datos en cualquiera de las réplicas).
-
-Los nombres de clúster no deben contener puntos.
-
-Los parámetros `host`, `port`, y opcionalmente `user`, `password`, `secure`, `compression` se especifican para cada servidor:
-- `host` – The address of the remote server. You can use either the domain or the IPv4 or IPv6 address. If you specify the domain, the server makes a DNS request when it starts, and the result is stored as long as the server is running. If the DNS request fails, the server doesn't start. If you change the DNS record, restart the server.
-- `port` – The TCP port for messenger activity (‘tcp_port’ en la configuración, generalmente establecido en 9000). No lo confundas con http_port.
-- `user` – Name of the user for connecting to a remote server. Default value: default. This user must have access to connect to the specified server. Access is configured in the users.xml file. For more information, see the section [Derechos de acceso](../../../operations/access-rights.md).
-- `password` – The password for connecting to a remote server (not masked). Default value: empty string.
-- `secure` - Use ssl para la conexión, por lo general también debe definir `port` = 9440. El servidor debe escuchar en `<tcp_port_secure>9440</tcp_port_secure>` y tener certificados correctos.
-- `compression` - Utilice la compresión de datos. Valor predeterminado: true.
-
-When specifying replicas, one of the available replicas will be selected for each of the shards when reading. You can configure the algorithm for load balancing (the preference for which replica to access) – see the [load_balancing](../../../operations/settings/settings.md#settings-load_balancing) configuración.
-Si no se establece la conexión con el servidor, habrá un intento de conectarse con un breve tiempo de espera. Si la conexión falla, se seleccionará la siguiente réplica, y así sucesivamente para todas las réplicas. Si el intento de conexión falló para todas las réplicas, el intento se repetirá de la misma manera, varias veces.
-Esto funciona a favor de la resiliencia, pero no proporciona una tolerancia completa a errores: un servidor remoto podría aceptar la conexión, pero podría no funcionar o funcionar mal.
-
-Puede especificar solo uno de los fragmentos (en este caso, el procesamiento de consultas debe denominarse remoto, en lugar de distribuido) o hasta cualquier número de fragmentos. En cada fragmento, puede especificar entre una y cualquier número de réplicas. Puede especificar un número diferente de réplicas para cada fragmento.
-
-Puede especificar tantos clústeres como desee en la configuración.
-
-Para ver los clústeres, utilice el ‘system.clusters’ tabla.
-
-El motor distribuido permite trabajar con un clúster como un servidor local. Sin embargo, el clúster es inextensible: debe escribir su configuración en el archivo de configuración del servidor (mejor aún, para todos los servidores del clúster).
-
-The Distributed engine requires writing clusters to the config file. Clusters from the config file are updated on the fly, without restarting the server. If you need to send a query to an unknown set of shards and replicas each time, you don't need to create a Distributed table – use the ‘remote’ función de tabla en su lugar. Vea la sección [Funciones de tabla](../../../sql-reference/table-functions/index.md).
-
-Hay dos métodos para escribir datos en un clúster:
-
-Primero, puede definir a qué servidores escribir en qué datos y realizar la escritura directamente en cada fragmento. En otras palabras, realice INSERT en las tablas que la tabla distribuida “looks at”. Esta es la solución más flexible, ya que puede usar cualquier esquema de fragmentación, que podría ser no trivial debido a los requisitos del área temática. Esta es también la solución más óptima ya que los datos se pueden escribir en diferentes fragmentos de forma completamente independiente.
-
-En segundo lugar, puede realizar INSERT en una tabla distribuida. En este caso, la tabla distribuirá los datos insertados a través de los propios servidores. Para escribir en una tabla distribuida, debe tener un conjunto de claves de fragmentación (el último parámetro). Además, si solo hay un fragmento, la operación de escritura funciona sin especificar la clave de fragmentación, ya que no significa nada en este caso.
-
-Cada fragmento puede tener un peso definido en el archivo de configuración. Por defecto, el peso es igual a uno. Los datos se distribuyen entre fragmentos en la cantidad proporcional al peso del fragmento. Por ejemplo, si hay dos fragmentos y el primero tiene un peso de 9 mientras que el segundo tiene un peso de 10, el primero se enviará 9 / 19 partes de las filas, y el segundo se enviará 10 / 19.
-
-Cada fragmento puede tener el ‘internal_replication’ parámetro definido en el archivo de configuración.
-
-Si este parámetro se establece en ‘true’, la operación de escritura selecciona la primera réplica en buen estado y escribe datos en ella. Utilice esta alternativa si la tabla Distribuida “looks at” tablas replicadas. En otras palabras, si la tabla donde se escribirán los datos los replicará por sí misma.
-
-Si se establece en ‘false’ (el valor predeterminado), los datos se escriben en todas las réplicas. En esencia, esto significa que la tabla distribuida replica los datos en sí. Esto es peor que usar tablas replicadas, porque no se verifica la consistencia de las réplicas y, con el tiempo, contendrán datos ligeramente diferentes.
-
-Para seleccionar el fragmento al que se envía una fila de datos, se analiza la expresión de fragmentación y su resto se toma de dividirlo por el peso total de los fragmentos. La fila se envía al fragmento que corresponde al medio intervalo de los restos de ‘prev_weight’ a ‘prev_weights + weight’, donde ‘prev_weights’ es el peso total de los fragmentos con el número más pequeño, y ‘weight’ es el peso de este fragmento. Por ejemplo, si hay dos fragmentos, y el primero tiene un peso de 9 mientras que el segundo tiene un peso de 10, la fila se enviará al primer fragmento para los restos del rango \[0, 9), y al segundo para los restos del rango \[9, 19).
-
-La expresión de fragmentación puede ser cualquier expresión de constantes y columnas de tabla que devuelva un entero. Por ejemplo, puede usar la expresión ‘rand()’ para la distribución aleatoria de datos, o ‘UserID’ para la distribución por el resto de dividir la ID del usuario (entonces los datos de un solo usuario residirán en un solo fragmento, lo que simplifica la ejecución de IN y JOIN por los usuarios). Si una de las columnas no se distribuye lo suficientemente uniformemente, puede envolverla en una función hash: intHash64(UserID) .
-
-Un simple recordatorio de la división es una solución limitada para sharding y no siempre es apropiado. Funciona para volúmenes medianos y grandes de datos (docenas de servidores), pero no para volúmenes muy grandes de datos (cientos de servidores o más). En este último caso, use el esquema de fragmentación requerido por el área asunto, en lugar de usar entradas en Tablas distribuidas.
-
-SELECT queries are sent to all the shards and work regardless of how data is distributed across the shards (they can be distributed completely randomly). When you add a new shard, you don't have to transfer the old data to it. You can write new data with a heavier weight – the data will be distributed slightly unevenly, but queries will work correctly and efficiently.
-
-Debería preocuparse por el esquema de fragmentación en los siguientes casos:
-
--   Se utilizan consultas que requieren unir datos (IN o JOIN) mediante una clave específica. Si esta clave fragmenta datos, puede usar IN local o JOIN en lugar de GLOBAL IN o GLOBAL JOIN, que es mucho más eficiente.
--   Se usa una gran cantidad de servidores (cientos o más) con una gran cantidad de consultas pequeñas (consultas de clientes individuales: sitios web, anunciantes o socios). Para que las pequeñas consultas no afecten a todo el clúster, tiene sentido ubicar datos para un solo cliente en un solo fragmento. Alternativamente, como lo hemos hecho en Yandex.Metrica, puede configurar sharding de dos niveles: divida todo el clúster en “layers”, donde una capa puede consistir en varios fragmentos. Los datos de un único cliente se encuentran en una sola capa, pero los fragmentos se pueden agregar a una capa según sea necesario y los datos se distribuyen aleatoriamente dentro de ellos. Las tablas distribuidas se crean para cada capa y se crea una única tabla distribuida compartida para consultas globales.
-
-Los datos se escriben de forma asíncrona. Cuando se inserta en la tabla, el bloque de datos se acaba de escribir en el sistema de archivos local. Los datos se envían a los servidores remotos en segundo plano tan pronto como sea posible. El período de envío de datos está gestionado por el [Distributed_directory_monitor_sleep_time_ms](../../../operations/settings/settings.md#distributed_directory_monitor_sleep_time_ms) y [Distributed_directory_monitor_max_sleep_time_ms](../../../operations/settings/settings.md#distributed_directory_monitor_max_sleep_time_ms) configuración. El `Distributed` el motor envía cada archivo con datos insertados por separado, pero puede habilitar el envío por lotes de archivos [distributed_directory_monitor_batch_inserts](../../../operations/settings/settings.md#distributed_directory_monitor_batch_inserts) configuración. Esta configuración mejora el rendimiento del clúster al utilizar mejor los recursos de red y servidor local. Debe comprobar si los datos se envían correctamente comprobando la lista de archivos (datos en espera de ser enviados) en el directorio de la tabla: `/var/lib/clickhouse/data/database/table/`.
-
-Si el servidor dejó de existir o tuvo un reinicio aproximado (por ejemplo, después de un error de dispositivo) después de un INSERT en una tabla distribuida, es posible que se pierdan los datos insertados. Si se detecta un elemento de datos dañado en el directorio de la tabla, se transfiere al ‘broken’ subdirectorio y ya no se utiliza.
-
-Cuando la opción max_parallel_replicas está habilitada, el procesamiento de consultas se paralela en todas las réplicas dentro de un solo fragmento. Para obtener más información, consulte la sección [max_parallel_replicas](../../../operations/settings/settings.md#settings-max_parallel_replicas).

----
-
-# Datos externos para el procesamiento de consultas {#external-data-for-query-processing}
-
-ClickHouse permite enviar a un servidor los datos necesarios para procesar una consulta, junto con una consulta SELECT. Estos datos se colocan en una tabla temporal (consulte la sección “Temporary tables”) y se puede utilizar en la consulta (por ejemplo, en operadores IN).
-
-Por ejemplo, si tiene un archivo de texto con identificadores de usuario importantes, puede cargarlo en el servidor junto con una consulta que utilice la filtración de esta lista.
-
-Si necesita ejecutar más de una consulta con un gran volumen de datos externos, no utilice esta función. Es mejor cargar los datos a la base de datos con anticipación.
-
-Los datos externos se pueden cargar mediante el cliente de línea de comandos (en modo no interactivo) o mediante la interfaz HTTP.
-
-En el cliente de línea de comandos, puede especificar una sección de parámetros en el formato
-
-``` bash
---external --file=... [--name=...] [--format=...] [--types=...|--structure=...]
-```
-
-Puede tener varias secciones como esta, para el número de tablas que se transmiten.
-
-**–external** – Marks the beginning of a clause.
-**–file** – Path to the file with the table dump, or -, which refers to stdin.
-Solo se puede recuperar una sola tabla de stdin.
-
-Los siguientes parámetros son opcionales: **–name**– Name of the table. If omitted, _data is used.
-**–format** – Data format in the file. If omitted, TabSeparated is used.
-
-Se requiere uno de los siguientes parámetros:**–types** – A list of comma-separated column types. For example: `UInt64,String`. The columns will be named _1, _2, …
-**–structure**– The table structure in the format`UserID UInt64`, `URL String`. Define los nombres y tipos de columna.
-
-Los archivos especificados en ‘file’ se analizará mediante el formato especificado en ‘format’ utilizando los tipos de datos especificados en ‘types’ o ‘structure’. La mesa será cargado en el servidor y accesibles, como una tabla temporal con el nombre de ‘name’.
-
-Ejemplos:
-
-``` bash
-$ echo -ne "1\n2\n3\n" | clickhouse-client --query="SELECT count() FROM test.visits WHERE TraficSourceID IN _data" --external --file=- --types=Int8
-849897
-$ cat /etc/passwd | sed 's/:/\t/g' | clickhouse-client --query="SELECT shell, count() AS c FROM passwd GROUP BY shell ORDER BY c DESC" --external --file=- --name=passwd --structure='login String, unused String, uid UInt16, gid UInt16, comment String, home String, shell String'
-/bin/sh 20
-/bin/false      5
-/bin/bash       4
-/usr/sbin/nologin       1
-/bin/sync       1
-```
-
-Cuando se utiliza la interfaz HTTP, los datos externos se pasan en el formato multipart/form-data. Cada tabla se transmite como un archivo separado. El nombre de la tabla se toma del nombre del archivo. El ‘query_string’ se pasa los parámetros ‘name_format’, ‘name_types’, y ‘name_structure’, donde ‘name’ es el nombre de la tabla a la que corresponden estos parámetros. El significado de los parámetros es el mismo que cuando se usa el cliente de línea de comandos.
-
-Ejemplo:
-
-``` bash
-$ cat /etc/passwd | sed 's/:/\t/g' > passwd.tsv
-
-$ curl -F 'passwd=@passwd.tsv;' 'http://localhost:8123/?query=SELECT+shell,+count()+AS+c+FROM+passwd+GROUP+BY+shell+ORDER+BY+c+DESC&passwd_structure=login+String,+unused+String,+uid+UInt16,+gid+UInt16,+comment+String,+home+String,+shell+String'
-/bin/sh 20
-/bin/false      5
-/bin/bash       4
-/usr/sbin/nologin       1
-/bin/sync       1
-```
-
-Para el procesamiento de consultas distribuidas, las tablas temporales se envían a todos los servidores remotos.

-`SELECT` consultas, el formato debe ser compatible para la entrada, y para realizar
-`INSERT` queries – for output. The available formats are listed in the
-[Formato](../../../interfaces/formats.md#formats) apartado.
-
-ClickHouse no permite especificar la ruta del sistema de archivos para`File`. Utilizará la carpeta definida por [camino](../../../operations/server-configuration-parameters/settings.md) configuración en la configuración del servidor.
-
-Al crear una tabla usando `File(Format)` crea un subdirectorio vacío en esa carpeta. Cuando los datos se escriben en esa tabla, se colocan en `data.Format` en ese subdirectorio.
-
-Puede crear manualmente esta subcarpeta y archivo en el sistema de archivos del servidor y luego [ATTACH](../../../sql-reference/statements/misc.md) para mostrar información con el nombre coincidente, para que pueda consultar datos desde ese archivo.
-
-!!! warning "Advertencia"
-    Tenga cuidado con esta funcionalidad, ya que ClickHouse no realiza un seguimiento de los cambios externos en dichos archivos. El resultado de las escrituras simultáneas a través de ClickHouse y fuera de ClickHouse no está definido.
-
-**Ejemplo:**
-
-**1.** Configurar el `file_engine_table` tabla:
-
-``` sql
-CREATE TABLE file_engine_table (name String, value UInt32) ENGINE=File(TabSeparated)
-```
-
-Por defecto, ClickHouse creará una carpeta `/var/lib/clickhouse/data/default/file_engine_table`.
-
-**2.** Crear manualmente `/var/lib/clickhouse/data/default/file_engine_table/data.TabSeparated` contener:
-
-``` bash
-$ cat data.TabSeparated
-one 1
-two 2
-```
-
-**3.** Consultar los datos:
-
-``` sql
-SELECT * FROM file_engine_table
-```

-
-## Uso en ClickHouse-local {#usage-in-clickhouse-local}
-
-En [Sistema abierto.](../../../operations/utilities/clickhouse-local.md#clickhouse-local) El motor de archivos acepta la ruta del archivo además de `Format`. Los flujos de entrada / salida predeterminados se pueden especificar utilizando nombres numéricos o legibles por humanos como `0` o `stdin`, `1` o `stdout`.
-**Ejemplo:**
-
-``` bash
-$ echo -e "1,2\n3,4" | clickhouse-local -q "CREATE TABLE table (a Int64, b Int64) ENGINE = File(CSV, stdin); SELECT a, b FROM table; DROP TABLE table"
-```

-El motor de tabla GenerateRandom produce datos aleatorios para el esquema de tabla determinado.
-
-Ejemplos de uso:
-
--   Se usa en la prueba para poblar una tabla grande reproducible.
--   Generar entrada aleatoria para pruebas de fuzzing.
-
-## Uso en el servidor ClickHouse {#usage-in-clickhouse-server}
-
-``` sql
-ENGINE = GenerateRandom(random_seed, max_string_length, max_array_length)

-
-Estructura de datos preparada para usar en [JOIN](../../../sql-reference/statements/select/join.md#select-join) operación.
-
-## Creación de una tabla {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
-) ENGINE = Join(join_strictness, join_type, k1[, k2, ...])
-```
-
-Vea la descripción detallada del [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) consulta.
-
-**Parámetros del motor**
-
--   `join_strictness` – [ÚNETE a la rigurosidad](../../../sql-reference/statements/select/join.md#select-join-types).
--   `join_type` – [Tipo de unión](../../../sql-reference/statements/select/join.md#select-join-types).
--   `k1[, k2, ...]` – Key columns from the `USING` cláusula que el `JOIN` operación se hace con.
-
-Entrar `join_strictness` y `join_type` parámetros sin comillas, por ejemplo, `Join(ANY, LEFT, col1)`. Deben coincidir con el `JOIN` operación para la que se utilizará la tabla. Si los parámetros no coinciden, ClickHouse no lanza una excepción y puede devolver datos incorrectos.
-
-## Uso de la tabla {#table-usage}
-
-### Ejemplo {#example}
-
-Creación de la tabla del lado izquierdo:
-
-``` sql
-CREATE TABLE id_val(`id` UInt32, `val` UInt32) ENGINE = TinyLog
-```
-
-``` sql
-INSERT INTO id_val VALUES (1,11)(2,12)(3,13)
-```
-
-Creando el lado derecho `Join` tabla:
-
-``` sql
-CREATE TABLE id_val_join(`id` UInt32, `val` UInt8) ENGINE = Join(ANY, LEFT, id)
-```
-
-``` sql
-INSERT INTO id_val_join VALUES (1,21)(1,22)(3,23)
-```
-
-Unirse a las tablas:
-
-``` sql
-SELECT * FROM id_val ANY LEFT JOIN id_val_join USING (id) SETTINGS join_use_nulls = 1
-```
-
-``` text
-┌─id─┬─val─┬─id_val_join.val─┐
-│  1 │  11 │              21 │
-│  2 │  12 │            ᴺᵁᴸᴸ │
-│  3 │  13 │              23 │
-└────┴─────┴─────────────────┘
-```
-
-Como alternativa, puede recuperar datos del `Join` tabla, especificando el valor de la clave de unión:
-
-``` sql
-SELECT joinGet('id_val_join', 'val', toUInt32(1))
-```
-
-``` text
-┌─joinGet('id_val_join', 'val', toUInt32(1))─┐
-│                                         21 │
-└────────────────────────────────────────────┘
-```
-
-### Selección e inserción de datos {#selecting-and-inserting-data}
-
-Usted puede utilizar `INSERT` consultas para agregar datos al `Join`-mesas de motor. Si la tabla se creó con el `ANY` estricta, se ignoran los datos de las claves duplicadas. Con el `ALL` estricta, se agregan todas las filas.
-
-No se puede realizar una `SELECT` consulta directamente desde la tabla. En su lugar, use uno de los siguientes métodos:
-
--   Coloque la mesa hacia el lado derecho en un `JOIN` clausula.
--   Llame al [joinGet](../../../sql-reference/functions/other-functions.md#joinget) función, que le permite extraer datos de la tabla de la misma manera que de un diccionario.
-
-### Limitaciones y ajustes {#join-limitations-and-settings}
-
-Al crear una tabla, se aplican los siguientes valores:
-
--   [Sistema abierto.](../../../operations/settings/settings.md#join_use_nulls)
--   [Método de codificación de datos:](../../../operations/settings/query-complexity.md#settings-max_rows_in_join)
--   [Método de codificación de datos:](../../../operations/settings/query-complexity.md#settings-max_bytes_in_join)
--   [join_overflow_mode](../../../operations/settings/query-complexity.md#settings-join_overflow_mode)
--   [join_any_take_last_row](../../../operations/settings/settings.md#settings-join_any_take_last_row)
-
-El `Join`-las tablas del motor no se pueden usar en `GLOBAL JOIN` operación.
-
-El `Join`-motor permite el uso [Sistema abierto.](../../../operations/settings/settings.md#join_use_nulls) ajuste en el `CREATE TABLE` instrucción. Y [SELECT](../../../sql-reference/statements/select/index.md) consulta permite el uso `join_use_nulls` demasiado. Si tienes diferentes `join_use_nulls` configuración, puede obtener un error al unirse a la tabla. Depende del tipo de JOIN. Cuando se utiliza [joinGet](../../../sql-reference/functions/other-functions.md#joinget) función, usted tiene que utilizar el mismo `join_use_nulls` ajuste en `CRATE TABLE` y `SELECT` instrucción.
-
-## Almacenamiento de datos {#data-storage}
-
-`Join` datos de la tabla siempre se encuentra en la memoria RAM. Al insertar filas en una tabla, ClickHouse escribe bloques de datos en el directorio del disco para que puedan restaurarse cuando se reinicie el servidor.
-
-Si el servidor se reinicia incorrectamente, el bloque de datos en el disco puede perderse o dañarse. En este caso, es posible que deba eliminar manualmente el archivo con datos dañados.

-# Memoria {#memory}
-
-El motor de memoria almacena datos en RAM, en forma sin comprimir. Los datos se almacenan exactamente en la misma forma en que se reciben cuando se leen. En otras palabras, la lectura de esta tabla es completamente gratuita.
-El acceso a los datos simultáneos está sincronizado. Los bloqueos son cortos: las operaciones de lectura y escritura no se bloquean entre sí.
-Los índices no son compatibles. La lectura está paralelizada.
-La productividad máxima (más de 10 GB/s) se alcanza en consultas simples, porque no hay lectura del disco, descomprimir o deserializar datos. (Cabe señalar que, en muchos casos, la productividad del motor MergeTree es casi tan alta.)
-Al reiniciar un servidor, los datos desaparecen de la tabla y la tabla queda vacía.
-Normalmente, el uso de este motor de tabla no está justificado. Sin embargo, se puede usar para pruebas y para tareas donde se requiere la velocidad máxima en un número relativamente pequeño de filas (hasta aproximadamente 100,000,000).
-
-El sistema utiliza el motor de memoria para tablas temporales con datos de consulta externos (consulte la sección “External data for processing a query”), y para la implementación de GLOBAL IN (véase la sección “IN operators”).

----
-
-# Fusionar {#merge}
-
-El `Merge` motor (no debe confundirse con `MergeTree`) no almacena datos en sí, pero permite leer de cualquier número de otras tablas simultáneamente.
-La lectura se paralela automáticamente. No se admite la escritura en una tabla. Al leer, se usan los índices de las tablas que realmente se están leyendo, si existen.
-El `Merge` engine acepta parámetros: el nombre de la base de datos y una expresión regular para las tablas.
-
-Ejemplo:
-
-``` sql
-Merge(hits, '^WatchLog')
-```
-
-Los datos se leerán de las tablas en el `hits` base de datos que tienen nombres que coinciden con la expresión regular ‘`^WatchLog`’.
-
-En lugar del nombre de la base de datos, puede usar una expresión constante que devuelva una cadena. Por ejemplo, `currentDatabase()`.
-
-Regular expressions — [Re2](https://github.com/google/re2) (soporta un subconjunto de PCRE), sensible a mayúsculas y minúsculas.
-Vea las notas sobre los símbolos de escape en expresiones regulares en el “match” apartado.
-
-Al seleccionar tablas para leer, el `Merge` no se seleccionará la tabla en sí, incluso si coincide con la expresión regular. Esto es para evitar bucles.
-Es posible crear dos `Merge` tablas que intentarán interminablemente leer los datos de los demás, pero esta no es una buena idea.
-
-La forma típica de usar el `Merge` para trabajar con un gran número de `TinyLog` tablas como si con una sola tabla.
-
-Ejemplo 2:
-
-Digamos que tiene una tabla antigua (WatchLog_old) y decidió cambiar la partición sin mover datos a una nueva tabla (WatchLog_new) y necesita ver datos de ambas tablas.
-
-``` sql
-CREATE TABLE WatchLog_old(date Date, UserId Int64, EventType String, Cnt UInt64)
-ENGINE=MergeTree(date, (UserId, EventType), 8192);
-INSERT INTO WatchLog_old VALUES ('2018-01-01', 1, 'hit', 3);
-
-CREATE TABLE WatchLog_new(date Date, UserId Int64, EventType String, Cnt UInt64)
-ENGINE=MergeTree PARTITION BY date ORDER BY (UserId, EventType) SETTINGS index_granularity=8192;
-INSERT INTO WatchLog_new VALUES ('2018-01-02', 2, 'hit', 3);
-
-CREATE TABLE WatchLog as WatchLog_old ENGINE=Merge(currentDatabase(), '^WatchLog');
-
-SELECT *
-FROM WatchLog
-```

-Administra datos en un servidor HTTP/HTTPS remoto. Este motor es similar
-a la [File](file.md) motor.
-
-## Uso del motor en el servidor ClickHouse {#using-the-engine-in-the-clickhouse-server}
-
-El `format` debe ser uno que ClickHouse pueda usar en
-`SELECT` consultas y, si es necesario, en `INSERTs`. Para obtener la lista completa de formatos admitidos, consulte
-[Formato](../../../interfaces/formats.md#formats).
-
-El `URL` debe ajustarse a la estructura de un localizador uniforme de recursos. La dirección URL especificada debe apuntar a un servidor
-que utiliza HTTP o HTTPS. Esto no requiere ningún
-encabezados adicionales para obtener una respuesta del servidor.
-
-`INSERT` y `SELECT` las consultas se transforman en `POST` y `GET` peticiones,
-respectivamente. Para el procesamiento `POST` solicitudes, el servidor remoto debe admitir
-[Codificación de transferencia fragmentada](https://en.wikipedia.org/wiki/Chunked_transfer_encoding).
-
-Puede limitar el número máximo de saltos de redirección HTTP GET utilizando el [Nombre de la red inalámbrica (SSID):](../../../operations/settings/settings.md#setting-max_http_get_redirects) configuración.
-
-**Ejemplo:**
-
-**1.** Crear un `url_engine_table` tabla en el servidor :
-
-``` sql
-CREATE TABLE url_engine_table (word String, value UInt64)
-ENGINE=URL('http://127.0.0.1:12345/', CSV)
-```
-
-**2.** Cree un servidor HTTP básico utilizando las herramientas estándar de Python 3 y
-comenzarlo:
-
-``` python3
-from http.server import BaseHTTPRequestHandler, HTTPServer
-
-class CSVHTTPServer(BaseHTTPRequestHandler):
-    def do_GET(self):
-        self.send_response(200)
-        self.send_header('Content-type', 'text/csv')
-        self.end_headers()
-
-        self.wfile.write(bytes('Hello,1\nWorld,2\n', "utf-8"))
-
-if __name__ == "__main__":
-    server_address = ('127.0.0.1', 12345)
-    HTTPServer(server_address, CSVHTTPServer).serve_forever()
-```
-
-``` bash
-$ python3 server.py
-```
-
-**3.** Solicitar datos:
-
-``` sql
-SELECT * FROM url_engine_table
-```
-
-``` text

-## ¿Por qué no usar algo como MapReduce? {#why-not-use-something-like-mapreduce}
-
-Podemos referirnos a sistemas como MapReduce como sistemas informáticos distribuidos en los que la operación de reducción se basa en la clasificación distribuida. La solución de código abierto más común en esta clase es [Acerca de nosotros](http://hadoop.apache.org). Yandex utiliza su solución interna, YT.
-
-Estos sistemas no son apropiados para consultas en línea debido a su alta latencia. En otras palabras, no se pueden usar como back-end para una interfaz web. Estos tipos de sistemas no son útiles para actualizaciones de datos en tiempo real. La clasificación distribuida no es la mejor manera de realizar operaciones de reducción si el resultado de la operación y todos los resultados intermedios (si los hay) se encuentran en la RAM de un único servidor, que generalmente es el caso de las consultas en línea. En tal caso, una tabla hash es una forma óptima de realizar operaciones de reducción. Un enfoque común para optimizar las tareas de reducción de mapas es la preagregación (reducción parcial) utilizando una tabla hash en RAM. El usuario realiza esta optimización manualmente. La clasificación distribuida es una de las principales causas de un rendimiento reducido cuando se ejecutan tareas simples de reducción de mapas.
-
-La mayoría de las implementaciones de MapReduce le permiten ejecutar código arbitrario en un clúster. Pero un lenguaje de consulta declarativo es más adecuado para OLAP para ejecutar experimentos rápidamente. Por ejemplo, Hadoop tiene Hive y Pig. También considere Cloudera Impala o Shark (obsoleto) para Spark, así como Spark SQL, Presto y Apache Drill. El rendimiento cuando se ejecutan tales tareas es muy subóptimo en comparación con los sistemas especializados, pero la latencia relativamente alta hace que sea poco realista utilizar estos sistemas como back-end para una interfaz web.

-## ¿Qué sucede si tengo un problema con las codificaciones al usar Oracle a través de ODBC? {#oracle-odbc-encodings}
-
-Si utiliza Oracle a través del controlador ODBC como fuente de diccionarios externos, debe establecer el valor `NLS_LANG` variable de entorno en `/etc/default/clickhouse`. Para obtener más información, consulte [Oracle NLS_LANG Preguntas frecuentes](https://www.oracle.com/technetwork/products/globalization/nls-lang-099431.html).
-
-**Ejemplo**
-
-``` sql
-NLS_LANG=RUSSIAN_RUSSIA.UTF8
-```
-
-## Cómo exporto datos de ClickHouse a un archivo? {#how-to-export-to-file}
-
-### Uso de la cláusula INTO OUTFILE {#using-into-outfile-clause}
-
-Añadir un [INTO OUTFILE](../sql-reference/statements/select/into-outfile.md#into-outfile-clause) cláusula a su consulta.
-
-Por ejemplo:
-
-``` sql
-SELECT * FROM table INTO OUTFILE 'file'
-```
-
-De forma predeterminada, ClickHouse usa el [TabSeparated](../interfaces/formats.md#tabseparated) formato de datos de salida. Para seleccionar el [formato de datos](../interfaces/formats.md), utilizar el [Cláusula FORMAT](../sql-reference/statements/select/format.md#format-clause).
-
-Por ejemplo:
-
-``` sql
-SELECT * FROM table INTO OUTFILE 'file' FORMAT CSV
-```
-
-### Uso de una tabla de motor de archivo {#using-a-file-engine-table}
-
-Ver [File](../engines/table-engines/special/file.md).
-
-### Uso de la redirección de línea de comandos {#using-command-line-redirection}
-
-``` sql
-$ clickhouse-client --query "SELECT * from table" --format FormatName > result.txt
-```
-
-Ver [Casa de clics-cliente](../interfaces/cli.md).

----
-
-# Datos de taxis de Nueva York {#new-york-taxi-data}
-
-Este conjunto de datos se puede obtener de dos maneras:
-
--   importación de datos sin procesar
--   descarga de particiones preparadas
-
-## Cómo importar los datos sin procesar {#how-to-import-the-raw-data}
-
-Consulte https://github.com/toddwschneider/nyc-taxi-data y http://tech.marksblogg.com/billion-nyc-taxi-rides-redshift.html para obtener la descripción de un conjunto de datos e instrucciones para descargar.
-
-La descarga dará como resultado aproximadamente 227 GB de datos sin comprimir en archivos CSV. La descarga tarda aproximadamente una hora en una conexión de 1 Gbit (la descarga paralela de s3.amazonaws.com recupera al menos la mitad de un canal de 1 Gbit).
-Es posible que algunos de los archivos no se descarguen por completo. Verifique los tamaños de archivo y vuelva a descargar cualquiera que parezca dudoso.
-
-Algunos de los archivos pueden contener filas no válidas. Puede arreglarlos de la siguiente manera:
-
-``` bash
-sed -E '/(.*,){18,}/d' data/yellow_tripdata_2010-02.csv > data/yellow_tripdata_2010-02.csv_
-sed -E '/(.*,){18,}/d' data/yellow_tripdata_2010-03.csv > data/yellow_tripdata_2010-03.csv_
-mv data/yellow_tripdata_2010-02.csv_ data/yellow_tripdata_2010-02.csv
-mv data/yellow_tripdata_2010-03.csv_ data/yellow_tripdata_2010-03.csv
-```
-
-Entonces los datos deben ser preprocesados en PostgreSQL. Esto creará selecciones de puntos en los polígonos (para hacer coincidir los puntos en el mapa con los distritos de la ciudad de Nueva York) y combinará todos los datos en una única tabla plana desnormalizada mediante el uso de una unión. Para hacer esto, deberá instalar PostgreSQL con soporte PostGIS.
-
-Tenga cuidado al correr `initialize_database.sh` y volver a verificar manualmente que todas las tablas se crearon correctamente.
-
-Se tarda entre 20 y 30 minutos en procesar los datos de cada mes en PostgreSQL, por un total de aproximadamente 48 horas.
-
-Puede comprobar el número de filas descargadas de la siguiente manera:
-
-``` bash
-$ time psql nyc-taxi-data -c "SELECT count(*) FROM trips;"
-## Count
- 1298979494
-(1 row)
-
-real    7m9.164s
-```
-
-(Esto es un poco más de 1.1 mil millones de filas reportadas por Mark Litwintschik en una serie de publicaciones de blog.)
-
-Los datos en PostgreSQL utilizan 370 GB de espacio.

-La instantánea de datos se crea a una velocidad de aproximadamente 50 MB por segundo. Al crear la instantánea, PostgreSQL lee desde el disco a una velocidad de aproximadamente 28 MB por segundo.
-Esto toma alrededor de 5 horas. El archivo TSV resultante es 590612904969 bytes.

----
-
-# Instalación {#installation}
-
-## Requisitos del sistema {#system-requirements}
-
-ClickHouse puede ejecutarse en cualquier Linux, FreeBSD o Mac OS X con arquitectura de CPU x86_64, AArch64 o PowerPC64LE.
-
-Los binarios oficiales preconstruidos generalmente se compilan para x86_64 y aprovechan el conjunto de instrucciones SSE 4.2, por lo que, a menos que se indique lo contrario, el uso de la CPU que lo admite se convierte en un requisito adicional del sistema. Aquí está el comando para verificar si la CPU actual tiene soporte para SSE 4.2:
-
-``` bash
-$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
-```
-
-Para ejecutar ClickHouse en procesadores que no admiten SSE 4.2 o tienen arquitectura AArch64 o PowerPC64LE, debe [construir ClickHouse a partir de fuentes](#from-sources) con los ajustes de configuración adecuados.
-
-## Opciones de instalación disponibles {#available-installation-options}
-
-### De paquetes DEB {#install-from-deb-packages}
-
-Se recomienda utilizar pre-compilado oficial `deb` Paquetes para Debian o Ubuntu. Ejecute estos comandos para instalar paquetes:
-
-``` bash
-{% include 'install/deb.sh' %}
-```
-
-Si desea utilizar la versión más reciente, reemplace `stable` con `testing` (esto se recomienda para sus entornos de prueba).
-
-También puede descargar e instalar paquetes manualmente desde [aqui](https://repo.clickhouse.tech/deb/stable/main/).
-
-#### Paquete {#packages}
-
--   `clickhouse-common-static` — Installs ClickHouse compiled binary files.
--   `clickhouse-server` — Creates a symbolic link for `clickhouse-server` e instala la configuración predeterminada del servidor.
--   `clickhouse-client` — Creates a symbolic link for `clickhouse-client` y otras herramientas relacionadas con el cliente. e instala los archivos de configuración del cliente.
--   `clickhouse-common-static-dbg` — Installs ClickHouse compiled binary files with debug info.
-
-### De paquetes RPM {#from-rpm-packages}
-
-Se recomienda utilizar pre-compilado oficial `rpm` También puede utilizar los paquetes para CentOS, RedHat y todas las demás distribuciones de Linux basadas en rpm.
-
-Primero, necesitas agregar el repositorio oficial:
-
-``` bash
-sudo yum install yum-utils
-sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
-sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64
-```
-
-Si desea utilizar la versión más reciente, reemplace `stable` con `testing` (esto se recomienda para sus entornos de prueba). El `prestable` etiqueta a veces está disponible también.
-
-A continuación, ejecute estos comandos para instalar paquetes:
-
-``` bash
-sudo yum install clickhouse-server clickhouse-client
-```
-
-También puede descargar e instalar paquetes manualmente desde [aqui](https://repo.clickhouse.tech/rpm/stable/x86_64).
-
-### De archivos Tgz {#from-tgz-archives}
-
-Se recomienda utilizar pre-compilado oficial `tgz` para todas las distribuciones de Linux, donde la instalación de `deb` o `rpm` paquetes no es posible.
-
-La versión requerida se puede descargar con `curl` o `wget` desde el repositorio https://repo.clickhouse.tech/tgz/.
-Después de eso, los archivos descargados deben desempaquetarse e instalarse con scripts de instalación. Ejemplo para la última versión:
-
-``` bash
-export LATEST_VERSION=`curl https://api.github.com/repos/ClickHouse/ClickHouse/tags 2>/dev/null | grep -Eo '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | head -n 1`
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-common-static-$LATEST_VERSION.tgz
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-common-static-dbg-$LATEST_VERSION.tgz
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-server-$LATEST_VERSION.tgz
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-client-$LATEST_VERSION.tgz
-
-tar -xzvf clickhouse-common-static-$LATEST_VERSION.tgz
-sudo clickhouse-common-static-$LATEST_VERSION/install/doinst.sh
-
-tar -xzvf clickhouse-common-static-dbg-$LATEST_VERSION.tgz
-sudo clickhouse-common-static-dbg-$LATEST_VERSION/install/doinst.sh
-
-tar -xzvf clickhouse-server-$LATEST_VERSION.tgz
-sudo clickhouse-server-$LATEST_VERSION/install/doinst.sh
-sudo /etc/init.d/clickhouse-server start
-
-tar -xzvf clickhouse-client-$LATEST_VERSION.tgz
-sudo clickhouse-client-$LATEST_VERSION/install/doinst.sh
-```
-
-Para los entornos de producción, se recomienda utilizar las últimas `stable`-versión. Puede encontrar su número en la página de GitHub https://github.com/ClickHouse/ClickHouse/tags con postfix `-stable`.
-
-### Desde Docker Image {#from-docker-image}
-
-Para ejecutar ClickHouse dentro de Docker, siga la guía en [Eje de acoplador](https://hub.docker.com/r/yandex/clickhouse-server/). Esas imágenes usan oficial `deb` paquetes dentro.
-
-### De fuentes {#from-sources}
-
-Para compilar manualmente ClickHouse, siga las instrucciones para [Linux](../development/build.md) o [Mac OS X](../development/build-osx.md).
-
-Puede compilar paquetes e instalarlos o usar programas sin instalar paquetes. Además, al construir manualmente, puede deshabilitar el requisito de SSE 4.2 o compilar para CPU AArch64.
-
-      Client: programs/clickhouse-client
-      Server: programs/clickhouse-server
-
-Tendrá que crear carpetas de datos y metadatos y `chown` para el usuario deseado. Sus rutas se pueden cambiar en la configuración del servidor (src/programs/server/config.xml), por defecto son:
-
-      /opt/clickhouse/data/default/
-      /opt/clickhouse/metadata/default/
-
-En Gentoo, puedes usar `emerge clickhouse` para instalar ClickHouse desde fuentes.
-
-## Lanzar {#launch}
-
-Para iniciar el servidor como demonio, ejecute:
-
-``` bash
-$ sudo service clickhouse-server start
-```
-
-Si no tienes `service` comando ejecutar como

-``` bash
-$ sudo /etc/init.d/clickhouse-server start
-```
-
-Vea los registros en el `/var/log/clickhouse-server/` directorio.
-
-Si el servidor no se inicia, compruebe las configuraciones en el archivo `/etc/clickhouse-server/config.xml`.
-
-También puede iniciar manualmente el servidor desde la consola:
-
-``` bash
-$ clickhouse-server --config-file=/etc/clickhouse-server/config.xml
-```
-
-En este caso, el registro se imprimirá en la consola, lo cual es conveniente durante el desarrollo.
-Si el archivo de configuración está en el directorio actual, no es necesario `--config-file` parámetro. De forma predeterminada, utiliza `./config.xml`.
-
-ClickHouse admite la configuración de restricción de acceso. Están ubicados en el `users.xml` archivo (junto a `config.xml`).
-De forma predeterminada, se permite el acceso desde cualquier lugar `default` usuario, sin una contraseña. Ver `user/default/networks`.
-Para obtener más información, consulte la sección [“Configuration Files”](../operations/configuration-files.md).
-
-Después de iniciar el servidor, puede usar el cliente de línea de comandos para conectarse a él:
-
-``` bash
-$ clickhouse-client
-```
-
-Por defecto, se conecta a `localhost:9000` en nombre del usuario `default` sin una contraseña. También se puede usar para conectarse a un servidor remoto usando `--host` argumento.
-
-El terminal debe usar codificación UTF-8.
-Para obtener más información, consulte la sección [“Command-line client”](../interfaces/cli.md).
-
-Ejemplo:
-
-``` bash
-$ ./clickhouse-client
-ClickHouse client version 0.0.18749.
-Connecting to localhost:9000.
-Connected to ClickHouse server version 0.0.18749.

-
-SELECT 1

-
-:)
-```
-
-**Felicidades, el sistema funciona!**
-

-# Zona de juegos ClickHouse {#clickhouse-playground}
-
-[Zona de juegos ClickHouse](https://play.clickhouse.tech?file=welcome) permite a las personas experimentar con ClickHouse ejecutando consultas al instante, sin configurar su servidor o clúster.
-Varios conjuntos de datos de ejemplo están disponibles en Playground, así como consultas de ejemplo que muestran las características de ClickHouse.
-
-Las consultas se ejecutan como un usuario de sólo lectura. Implica algunas limitaciones:
-
--   No se permiten consultas DDL
--   Las consultas INSERT no están permitidas
-
-También se aplican los siguientes valores:
-- [`max_result_bytes=10485760`](../operations/settings/query_complexity/#max-result-bytes)
-- [`max_result_rows=2000`](../operations/settings/query_complexity/#setting-max_result_rows)
-- [`result_overflow_mode=break`](../operations/settings/query_complexity/#result-overflow-mode)
-- [`max_execution_time=60000`](../operations/settings/query_complexity/#max-execution-time)
-
-ClickHouse Playground da la experiencia de m2.pequeño
-[Servicio administrado para ClickHouse](https://cloud.yandex.com/services/managed-clickhouse)
-instancia alojada en [El Yandex.Nube](https://cloud.yandex.com/).
-Más información sobre [proveedores de la nube](../commercial/cloud.md).
-
-La interfaz web de ClickHouse Playground realiza solicitudes a través de ClickHouse [HTTP API](../interfaces/http.md).
-El backend Playground es solo un clúster ClickHouse sin ninguna aplicación adicional del lado del servidor.
-El punto final HTTPS de ClickHouse también está disponible como parte de Playground.
-
-Puede realizar consultas al patio de recreo utilizando cualquier cliente HTTP, por ejemplo [rizo](https://curl.haxx.se) o [wget](https://www.gnu.org/software/wget/), o configurar una conexión usando [JDBC](../interfaces/jdbc.md) o [ODBC](../interfaces/odbc.md) controlador.

-# Tutorial de ClickHouse {#clickhouse-tutorial}
-
-## Qué Esperar de Este Tutorial? {#what-to-expect-from-this-tutorial}
-
-Al pasar por este tutorial, aprenderá cómo configurar un clúster de ClickHouse simple. Será pequeño, pero tolerante a fallos y escalable. Luego usaremos uno de los conjuntos de datos de ejemplo para llenarlo con datos y ejecutar algunas consultas de demostración.
-
-## Configuración de nodo único {#single-node-setup}
-
-Para posponer las complejidades de un entorno distribuido, comenzaremos con la implementación de ClickHouse en un único servidor o máquina virtual. ClickHouse generalmente se instala desde [deb](install.md#install-from-deb-packages) o [RPM](install.md#from-rpm-packages) paquetes, pero hay [alternativa](install.md#from-docker-image) para los sistemas operativos que no los admiten.
-
-Por ejemplo, ha elegido `deb` paquetes y ejecutado:
-
-``` bash
-{% include 'install/deb.sh' %}
-```
-
-¿Qué tenemos en los paquetes que tengo instalados:
-
--   `clickhouse-client` el paquete contiene [Casa de clics-cliente](../interfaces/cli.md) aplicación, cliente interactivo de la consola ClickHouse.
--   `clickhouse-common` El paquete contiene un archivo ejecutable ClickHouse.
--   `clickhouse-server` El paquete contiene archivos de configuración para ejecutar ClickHouse como servidor.
-
-Los archivos de configuración del servidor se encuentran en `/etc/clickhouse-server/`. Antes de ir más lejos, tenga en cuenta el `<path>` elemento en `config.xml`. La ruta determina la ubicación para el almacenamiento de datos, por lo que debe ubicarse en un volumen con gran capacidad de disco; el valor predeterminado es `/var/lib/clickhouse/`. Si desea ajustar la configuración, no es útil editar directamente `config.xml` archivo, teniendo en cuenta que podría ser reescrito en futuras actualizaciones de paquetes. La forma recomendada de anular los elementos de configuración es crear [archivos en config.directorio d](../operations/configuration-files.md) que sirven como “patches” de configuración.XML.
-
-Como habrás notado, `clickhouse-server` no se inicia automáticamente después de la instalación del paquete. Tampoco se reiniciará automáticamente después de las actualizaciones. La forma en que inicia el servidor depende de su sistema de inicio, por lo general, es:
-
-``` bash
-sudo service clickhouse-server start
-```
-
-o
-
-``` bash
-sudo /etc/init.d/clickhouse-server start
-```
-
-La ubicación predeterminada para los registros del servidor es `/var/log/clickhouse-server/`. El servidor está listo para manejar las conexiones de cliente una vez que registra el `Ready for connections` mensaje.
-
-Una vez que el `clickhouse-server` está en funcionamiento, podemos usar `clickhouse-client` para conectarse al servidor y ejecutar algunas consultas de prueba como `SELECT "Hello, world!";`.
-
-<details markdown="1">
-
-<summary>Consejos rápidos para clickhouse-cliente</summary>
-
-Modo interactivo:
-
-``` bash
-clickhouse-client
-clickhouse-client --host=... --port=... --user=... --password=...
-```
-
-Habilitar consultas multilínea:
-
-``` bash
-clickhouse-client -m
-clickhouse-client --multiline
-```
-
-Ejecutar consultas en modo por lotes:
-
-``` bash
-clickhouse-client --query='SELECT 1'
-echo 'SELECT 1' | clickhouse-client
-clickhouse-client <<< 'SELECT 1'
-```
-
-Insertar datos de un archivo en el formato especificado:
-
-``` bash
-clickhouse-client --query='INSERT INTO table VALUES' < data.txt
-clickhouse-client --query='INSERT INTO table FORMAT TabSeparated' < data.tsv
-```
-
-</details>
-
-## Importar conjunto de datos de muestra {#import-sample-dataset}
-
-Ahora es el momento de llenar nuestro servidor ClickHouse con algunos datos de muestra. En este tutorial, usaremos los datos anónimos de Yandex.Metrica, el primer servicio que ejecuta ClickHouse en forma de producción antes de que se convirtiera en código abierto (más sobre eso en [sección de historia](../introduction/history.md)). Hay [múltiples formas de importar Yandex.Conjunto de datos de Metrica](example-datasets/metrica.md), y por el bien del tutorial, iremos con el más realista.
-
-### Descargar y extraer datos de tabla {#download-and-extract-table-data}
-
-``` bash
-curl https://datasets.clickhouse.tech/hits/tsv/hits_v1.tsv.xz | unxz --threads=`nproc` > hits_v1.tsv
-curl https://datasets.clickhouse.tech/visits/tsv/visits_v1.tsv.xz | unxz --threads=`nproc` > visits_v1.tsv
-```
-
-Los archivos extraídos tienen un tamaño de aproximadamente 10 GB.
-
-### Crear tablas {#create-tables}
-
-Como en la mayoría de los sistemas de gestión de bases de datos, ClickHouse agrupa lógicamente las tablas en “databases”. Hay un `default` base de datos, pero crearemos una nueva llamada `tutorial`:
-
-``` bash
-clickhouse-client --query "CREATE DATABASE IF NOT EXISTS tutorial"
-```
-
-La sintaxis para crear tablas es mucho más complicada en comparación con las bases de datos (ver [referencia](../sql-reference/statements/create.md). En general `CREATE TABLE` declaración tiene que especificar tres cosas clave:
-
-1.  Nombre de la tabla que se va a crear.
-2.  Table schema, i.e. list of columns and their [tipos de datos](../sql-reference/data-types/index.md).
-3.  [Motor de tabla](../engines/table-engines/index.md) y su configuración, que determina todos los detalles sobre cómo se ejecutarán físicamente las consultas a esta tabla.
-
-El Yandex.Metrica es un servicio de análisis web, y el conjunto de datos de muestra no cubre toda su funcionalidad, por lo que solo hay dos tablas para crear:
-
--   `hits` es una tabla con cada acción realizada por todos los usuarios en todos los sitios web cubiertos por el servicio.
--   `visits` es una tabla que contiene sesiones precompiladas en lugar de acciones individuales.
-
-Veamos y ejecutemos las consultas de tabla de creación real para estas tablas:

-Puede ejecutar esas consultas utilizando el modo interactivo de `clickhouse-client` (simplemente ejecútelo en un terminal sin especificar una consulta por adelantado) o pruebe algunos [interfaz alternativa](../interfaces/index.md) Si quieres.
-
-Como podemos ver, `hits_v1` utiliza el [motor básico MergeTree](../engines/table-engines/mergetree-family/mergetree.md), mientras que el `visits_v1` utiliza el [Derrumbar](../engines/table-engines/mergetree-family/collapsingmergetree.md) variante.
-
-### Importar datos {#import-data}
-
-La importación de datos a ClickHouse se realiza a través de [INSERT INTO](../sql-reference/statements/insert-into.md) consulta como en muchas otras bases de datos SQL. Sin embargo, los datos generalmente se proporcionan en uno de los [Formatos de serialización compatibles](../interfaces/formats.md) en lugar de `VALUES` cláusula (que también es compatible).
-
-Los archivos que descargamos anteriormente están en formato separado por tabuladores, así que aquí le mostramos cómo importarlos a través del cliente de la consola:
-
-``` bash
-clickhouse-client --query "INSERT INTO tutorial.hits_v1 FORMAT TSV" --max_insert_block_size=100000 < hits_v1.tsv
-clickhouse-client --query "INSERT INTO tutorial.visits_v1 FORMAT TSV" --max_insert_block_size=100000 < visits_v1.tsv
-```
-
-ClickHouse tiene un montón de [ajustes para sintonizar](../operations/settings/index.md) y una forma de especificarlos en el cliente de la consola es a través de argumentos, como podemos ver con `--max_insert_block_size`. La forma más fácil de averiguar qué configuraciones están disponibles, qué significan y cuáles son los valores predeterminados es consultar el `system.settings` tabla:
-
-``` sql
-SELECT name, value, changed, description
-FROM system.settings
-WHERE name LIKE '%max_insert_b%'
-FORMAT TSV
-
-max_insert_block_size    1048576    0    "The maximum block size for insertion, if we control the creation of blocks for insertion."
-```
-
-Opcionalmente se puede [OPTIMIZE](../sql-reference/statements/misc.md#misc_operations-optimize) las tablas después de la importación. Las tablas que están configuradas con un motor de la familia MergeTree siempre fusionan partes de datos en segundo plano para optimizar el almacenamiento de datos (o al menos verificar si tiene sentido). Estas consultas obligan al motor de tablas a realizar la optimización del almacenamiento en este momento en lugar de algún tiempo después:
-
-``` bash
-clickhouse-client --query "OPTIMIZE TABLE tutorial.hits_v1 FINAL"
-clickhouse-client --query "OPTIMIZE TABLE tutorial.visits_v1 FINAL"
-```
-
-Estas consultas inician una operación intensiva de E / S y CPU, por lo que si la tabla recibe datos nuevos de manera consistente, es mejor dejarlos solos y dejar que las fusiones se ejecuten en segundo plano.
-
-Ahora podemos comprobar si la importación de la tabla fue exitosa:
-
-``` bash
-clickhouse-client --query "SELECT COUNT(*) FROM tutorial.hits_v1"
-clickhouse-client --query "SELECT COUNT(*) FROM tutorial.visits_v1"
-```
-
-## Consultas de ejemplo {#example-queries}
-
-``` sql
-SELECT
-    StartURL AS URL,
-    AVG(Duration) AS AvgDuration
-FROM tutorial.visits_v1
-WHERE StartDate BETWEEN '2014-03-23' AND '2014-03-30'
-GROUP BY URL
-ORDER BY AvgDuration DESC
-LIMIT 10
-```
-
-``` sql
-SELECT
-    sum(Sign) AS visits,
-    sumIf(Sign, has(Goals.ID, 1105530)) AS goal_visits,
-    (100. * goal_visits) / visits AS goal_percent
-FROM tutorial.visits_v1
-WHERE (CounterID = 912887) AND (toYYYYMM(StartDate) = 201403) AND (domain(StartURL) = 'yandex.ru')
-```
-
-## Implementación de clúster {#cluster-deployment}
-
-El clúster ClickHouse es un clúster homogéneo. Pasos para configurar:
-
-1.  Instale el servidor ClickHouse en todas las máquinas del clúster
-2.  Configurar configuraciones de clúster en archivos de configuración
-3.  Crear tablas locales en cada instancia
-4.  Crear un [Tabla distribuida](../engines/table-engines/special/distributed.md)
-
-[Tabla distribuida](../engines/table-engines/special/distributed.md) es en realidad una especie de “view” a las tablas locales del clúster ClickHouse. La consulta SELECT de una tabla distribuida se ejecuta utilizando recursos de todos los fragmentos del clúster. Puede especificar configuraciones para varios clústeres y crear varias tablas distribuidas que proporcionen vistas a diferentes clústeres.
-
-Ejemplo de configuración para un clúster con tres fragmentos, una réplica cada uno:
-
-``` xml
-<remote_servers>
-    <perftest_3shards_1replicas>
-        <shard>
-            <replica>
-                <host>example-perftest01j.yandex.ru</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-        <shard>
-            <replica>
-                <host>example-perftest02j.yandex.ru</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-        <shard>
-            <replica>
-                <host>example-perftest03j.yandex.ru</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-    </perftest_3shards_1replicas>
-</remote_servers>
-```
-
-Para más demostraciones, vamos a crear una nueva tabla local con la misma `CREATE TABLE` consulta que utilizamos para `hits_v1`, pero nombre de tabla diferente:
-
-``` sql
-CREATE TABLE tutorial.hits_local (...) ENGINE = MergeTree() ...
-```
-
-Creación de una tabla distribuida que proporcione una vista en las tablas locales del clúster:
-
-``` sql
-CREATE TABLE tutorial.hits_all AS tutorial.hits_local
-ENGINE = Distributed(perftest_3shards_1replicas, tutorial, hits_local, rand());
-```
-
-Una práctica común es crear tablas distribuidas similares en todas las máquinas del clúster. Permite ejecutar consultas distribuidas en cualquier máquina del clúster. También hay una opción alternativa para crear una tabla distribuida temporal para una consulta SELECT determinada usando [remoto](../sql-reference/table-functions/remote.md) función de la tabla.
-
-Vamos a correr [INSERT SELECT](../sql-reference/statements/insert-into.md) en la tabla Distributed para extender la tabla a varios servidores.
-
-``` sql
-INSERT INTO tutorial.hits_all SELECT * FROM tutorial.hits_v1;
-```
-
-!!! warning "Aviso"
-    Este enfoque no es adecuado para la fragmentación de tablas grandes. Hay una herramienta separada [Método de codificación de datos:](../operations/utilities/clickhouse-copier.md) que puede volver a fragmentar tablas grandes arbitrarias.
-
-Como era de esperar, las consultas computacionalmente pesadas se ejecutan N veces más rápido si utilizan 3 servidores en lugar de uno.
-
-En este caso, hemos utilizado un clúster con 3 fragmentos, y cada uno contiene una sola réplica.
-
-Para proporcionar resiliencia en un entorno de producción, se recomienda que cada fragmento contenga 2-3 réplicas distribuidas entre varias zonas de disponibilidad o centros de datos (o al menos racks). Tenga en cuenta que ClickHouse admite un número ilimitado de réplicas.
-
-Ejemplo de configuración para un clúster de un fragmento que contiene tres réplicas:
-
-``` xml
-<remote_servers>
-    ...
-    <perftest_1shards_3replicas>
-        <shard>
-            <replica>
-                <host>example-perftest01j.yandex.ru</host>
-                <port>9000</port>
-             </replica>
-             <replica>
-                <host>example-perftest02j.yandex.ru</host>
-                <port>9000</port>
-             </replica>
-             <replica>
-                <host>example-perftest03j.yandex.ru</host>
-                <port>9000</port>
-             </replica>
-        </shard>
-    </perftest_1shards_3replicas>
-</remote_servers>
-```
-
-Para habilitar la replicación nativa [ZooKeeper](http://zookeeper.apache.org/) se requiere. ClickHouse se encarga de la coherencia de los datos en todas las réplicas y ejecuta el procedimiento de restauración después de la falla automáticamente. Se recomienda implementar el clúster ZooKeeper en servidores independientes (donde no se están ejecutando otros procesos, incluido ClickHouse).
-
-!!! note "Nota"
-    ZooKeeper no es un requisito estricto: en algunos casos simples, puede duplicar los datos escribiéndolos en todas las réplicas de su código de aplicación. Este enfoque es **ni** recomendado, en este caso, ClickHouse no podrá garantizar la coherencia de los datos en todas las réplicas. Por lo tanto, se convierte en responsabilidad de su aplicación.
-
-Las ubicaciones de ZooKeeper se especifican en el archivo de configuración:
-
-``` xml
-<zookeeper>
-    <node>
-        <host>zoo01.yandex.ru</host>
-        <port>2181</port>
-    </node>
-    <node>
-        <host>zoo02.yandex.ru</host>
-        <port>2181</port>
-    </node>
-    <node>
-        <host>zoo03.yandex.ru</host>
-        <port>2181</port>
-    </node>
-</zookeeper>
-```
-
-Además, necesitamos establecer macros para identificar cada fragmento y réplica que se utilizan en la creación de tablas:
-
-``` xml
-<macros>
-    <shard>01</shard>
-    <replica>01</replica>
-</macros>
-```
-
-Si no hay réplicas en este momento en la creación de la tabla replicada, se crea una instancia de una nueva primera réplica. Si ya hay réplicas activas, la nueva réplica clona los datos de las existentes. Tiene la opción de crear primero todas las tablas replicadas y, a continuación, insertar datos en ella. Otra opción es crear algunas réplicas y agregar las otras después o durante la inserción de datos.
-
-``` sql
-CREATE TABLE tutorial.hits_replica (...)
-ENGINE = ReplcatedMergeTree(
-    '/clickhouse_perftest/tables/{shard}/hits',
-    '{replica}'
-)
-...
-```
-
-Aquí usamos [ReplicatedMergeTree](../engines/table-engines/mergetree-family/replication.md) motor de mesa. En los parámetros, especificamos la ruta ZooKeeper que contiene identificadores de fragmentos y réplicas.
-
-``` sql
-INSERT INTO tutorial.hits_replica SELECT * FROM tutorial.hits_local;
-```
-
-La replicación funciona en modo multi-master. Los datos se pueden cargar en cualquier réplica y el sistema los sincroniza automáticamente con otras instancias. La replicación es asíncrona, por lo que en un momento dado, no todas las réplicas pueden contener datos insertados recientemente. Al menos una réplica debe estar disponible para permitir la ingestión de datos. Otros sincronizarán los datos y repararán la coherencia una vez que vuelvan a activarse. Tenga en cuenta que este enfoque permite la baja posibilidad de una pérdida de datos recientemente insertados.

-# Aplicación de un modelo Catboost en ClickHouse {#applying-catboost-model-in-clickhouse}
-
-[CatBoost](https://catboost.ai) es una biblioteca de impulso de gradiente libre y de código abierto desarrollada en [Yandex](https://yandex.com/company/) para el aprendizaje automático.
-
-Con esta instrucción, aprenderá a aplicar modelos preentrenados en ClickHouse ejecutando la inferencia de modelos desde SQL.
-
-Para aplicar un modelo CatBoost en ClickHouse:
-
-1.  [Crear una tabla](#create-table).
-2.  [Insertar los datos en la tabla](#insert-data-to-table).
-3.  [Integrar CatBoost en ClickHouse](#integrate-catboost-into-clickhouse) (Paso opcional).
-4.  [Ejecute la inferencia del modelo desde SQL](#run-model-inference).
-
-Para obtener más información sobre la formación de modelos CatBoost, consulte [Entrenamiento y aplicación de modelos](https://catboost.ai/docs/features/training.html#training).
-
-## Requisito {#prerequisites}
-
-Si no tienes el [Acoplador](https://docs.docker.com/install/) sin embargo, instalarlo.
-
-!!! note "Nota"
-    [Acoplador](https://www.docker.com) es una plataforma de software que le permite crear contenedores que aíslan una instalación de CatBoost y ClickHouse del resto del sistema.
-
-Antes de aplicar un modelo CatBoost:
-
-**1.** Tire de la [Imagen de acoplador](https://hub.docker.com/r/yandex/tutorial-catboost-clickhouse) del registro:
-
-``` bash
-$ docker pull yandex/tutorial-catboost-clickhouse
-```
-
-Esta imagen de Docker contiene todo lo que necesita para ejecutar CatBoost y ClickHouse: código, tiempo de ejecución, bibliotecas, variables de entorno y archivos de configuración.
-
-**2.** Asegúrese de que la imagen de Docker se haya extraído correctamente:
-
-``` bash
-$ docker image ls
-REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
-yandex/tutorial-catboost-clickhouse   latest              622e4d17945b        22 hours ago        1.37GB
-```
-
-**3.** Inicie un contenedor Docker basado en esta imagen:
-
-``` bash
-$ docker run -it -p 8888:8888 yandex/tutorial-catboost-clickhouse
-```
-
-## 1. Crear una tabla {#create-table}
-
-Para crear una tabla ClickHouse para el ejemplo de capacitación:
-
-**1.** Inicie el cliente de consola ClickHouse en el modo interactivo:
-
-``` bash
-$ clickhouse client
-```
-
-!!! note "Nota"
-    El servidor ClickHouse ya se está ejecutando dentro del contenedor Docker.
-
-**2.** Cree la tabla usando el comando:
-
-``` sql
-:) CREATE TABLE amazon_train
-(
-    date Date MATERIALIZED today(),
-    ACTION UInt8,
-    RESOURCE UInt32,
-    MGR_ID UInt32,
-    ROLE_ROLLUP_1 UInt32,
-    ROLE_ROLLUP_2 UInt32,
-    ROLE_DEPTNAME UInt32,
-    ROLE_TITLE UInt32,
-    ROLE_FAMILY_DESC UInt32,
-    ROLE_FAMILY UInt32,
-    ROLE_CODE UInt32
-)
-ENGINE = MergeTree ORDER BY date
-```
-
-**3.** Salir del cliente de la consola ClickHouse:
-
-``` sql
-:) exit
-```
-
-## 2. Insertar los datos en la tabla {#insert-data-to-table}
-
-Para insertar los datos:
-
-**1.** Ejecute el siguiente comando:
-
-``` bash
-$ clickhouse client --host 127.0.0.1 --query 'INSERT INTO amazon_train FORMAT CSVWithNames' < ~/amazon/train.csv
-```
-
-**2.** Inicie el cliente de consola ClickHouse en el modo interactivo:
-
-``` bash
-$ clickhouse client
-```
-
-**3.** Asegúrese de que los datos se hayan cargado:
-
-``` sql
-:) SELECT count() FROM amazon_train
-
-SELECT count()
-FROM amazon_train
-
-+-count()-+
-|   65538 |
-+-------+
-```
-
-## 3. Integrar CatBoost en ClickHouse {#integrate-catboost-into-clickhouse}
-
-!!! note "Nota"
-    **Paso opcional.** La imagen de Docker contiene todo lo que necesita para ejecutar CatBoost y ClickHouse.
-
-Para integrar CatBoost en ClickHouse:
-
-**1.** Construir la biblioteca de evaluación.
-
-La forma más rápida de evaluar un modelo CatBoost es compilar `libcatboostmodel.<so|dll|dylib>` biblioteca. Para obtener más información acerca de cómo construir la biblioteca, vea [Documentación de CatBoost](https://catboost.ai/docs/concepts/c-plus-plus-api_dynamic-c-pluplus-wrapper.html).
-
-**2.** Cree un nuevo directorio en cualquier lugar y con cualquier nombre, por ejemplo, `data` y poner la biblioteca creada en ella. La imagen de Docker ya contiene la biblioteca `data/libcatboostmodel.so`.
-
-**3.** Cree un nuevo directorio para el modelo de configuración en cualquier lugar y con cualquier nombre, por ejemplo, `models`.
-
-**4.** Cree un archivo de configuración de modelo con cualquier nombre, por ejemplo, `models/amazon_model.xml`.
-
-**5.** Describir la configuración del modelo:
-
-``` xml
-<models>
-    <model>
-        <!-- Model type. Now catboost only. -->
-        <type>catboost</type>
-        <!-- Model name. -->
-        <name>amazon</name>
-        <!-- Path to trained model. -->
-        <path>/home/catboost/tutorial/catboost_model.bin</path>
-        <!-- Update interval. -->
-        <lifetime>0</lifetime>
-    </model>
-</models>
-```
-
-**6.** Agregue la ruta de acceso a CatBoost y la configuración del modelo a la configuración de ClickHouse:
-
-``` xml
-<!-- File etc/clickhouse-server/config.d/models_config.xml. -->
-<catboost_dynamic_library_path>/home/catboost/data/libcatboostmodel.so</catboost_dynamic_library_path>
-<models_config>/home/catboost/models/*_model.xml</models_config>
-```
-
-## 4. Ejecute la inferencia del modelo desde SQL {#run-model-inference}
-
-Para el modelo de prueba, ejecute el cliente ClickHouse `$ clickhouse client`.
-
-Asegurémonos de que el modelo esté funcionando:
-
-``` sql
-:) SELECT
-    modelEvaluate('amazon',
-                RESOURCE,
-                MGR_ID,
-                ROLE_ROLLUP_1,
-                ROLE_ROLLUP_2,
-                ROLE_DEPTNAME,
-                ROLE_TITLE,
-                ROLE_FAMILY_DESC,
-                ROLE_FAMILY,
-                ROLE_CODE) > 0 AS prediction,
-    ACTION AS target
-FROM amazon_train
-LIMIT 10
-```
-
-!!! note "Nota"
-    Función [modelEvaluar](../sql-reference/functions/other-functions.md#function-modelevaluate) devuelve tupla con predicciones sin procesar por clase para modelos multiclase.
-
-Vamos a predecir la probabilidad:
-
-``` sql
-:) SELECT
-    modelEvaluate('amazon',
-                RESOURCE,
-                MGR_ID,
-                ROLE_ROLLUP_1,
-                ROLE_ROLLUP_2,
-                ROLE_DEPTNAME,
-                ROLE_TITLE,
-                ROLE_FAMILY_DESC,
-                ROLE_FAMILY,
-                ROLE_CODE) AS prediction,
-    1. / (1 + exp(-prediction)) AS probability,
-    ACTION AS target
-FROM amazon_train
-LIMIT 10
-```
-
-!!! note "Nota"
-    Más información sobre [exp()](../sql-reference/functions/math-functions.md) función.
-
-Vamos a calcular LogLoss en la muestra:
-
-``` sql
-:) SELECT -avg(tg * log(prob) + (1 - tg) * log(1 - prob)) AS logloss
-FROM
-(
-    SELECT
-        modelEvaluate('amazon',
-                    RESOURCE,
-                    MGR_ID,
-                    ROLE_ROLLUP_1,
-                    ROLE_ROLLUP_2,
-                    ROLE_DEPTNAME,
-                    ROLE_TITLE,
-                    ROLE_FAMILY_DESC,
-                    ROLE_FAMILY,
-                    ROLE_CODE) AS prediction,
-        1. / (1. + exp(-prediction)) AS prob,
-        ACTION AS tg
-    FROM amazon_train
-)
-```

-# ¿Qué es ClickHouse? {#what-is-clickhouse}
-
-ClickHouse es un sistema de gestión de bases de datos (DBMS), orientado a columnas, para el procesamiento analítico de consultas en línea (OLAP).
-
-En un DBMS “normal”, orientado a filas, los datos se almacenan en este orden:
-
-| Fila | Argumento   | JavaEnable | Titular                   | GoodEvent | EventTime           |
-|------|-------------|------------|---------------------------|-----------|---------------------|

-En otras palabras, todos los valores relacionados con una fila se almacenan físicamente uno junto al otro.
-
-Ejemplos de un DBMS orientado a filas son MySQL, Postgres y MS SQL Server.
-
-En un DBMS orientado a columnas, los datos se almacenan así:
-
-| Fila:       | #0                       | #1                 | #2                 | #N |

-
-Estos ejemplos solo muestran el orden en el que se organizan los datos. Los valores de diferentes columnas se almacenan por separado y los datos de la misma columna se almacenan juntos.
-
-Ejemplos de un DBMS orientado a columnas: Vertica, Paraccel (Actian Matrix y Amazon Redshift), Sybase IQ, Exasol, Infobright, InfiniDB, MonetDB (VectorWise y Actian Vector), LucidDB, SAP HANA, Google Dremel, Google PowerDrill, Druid y kdb+.
-
-Los diferentes modos de ordenar los datos al guardarlos se adecúan mejor a diferentes escenarios. El escenario de acceso a los datos se refiere a qué consultas se hacen, con qué frecuencia y en qué proporción; cuántos datos se leen para cada tipo de consulta - filas, columnas y bytes; la relación entre lectura y actualización de datos; el tamaño de trabajo de los datos y qué tan localmente son usados; si se usan transacciones y qué tan aisladas están;requerimientos de replicación de los datos y de integridad lógica, requerimientos de latencia y caudal (throughput) para cada tipo de consulta, y cosas por el estilo.
-
-Cuanto mayor sea la carga en el sistema, más importante es personalizar el sistema configurado para que coincida con los requisitos del escenario de uso, y más fino será esta personalización. No existe un sistema que sea igualmente adecuado para escenarios significativamente diferentes. Si un sistema es adaptable a un amplio conjunto de escenarios, bajo una carga alta, el sistema manejará todos los escenarios igualmente mal, o funcionará bien para solo uno o algunos de los escenarios posibles.
-
-## Propiedades clave del escenario OLAP {#key-properties-of-olap-scenario}
-
--   La gran mayoría de las solicitudes son para acceso de lectura.
--   Los datos se actualizan en lotes bastante grandes (\> 1000 filas), no por filas individuales; o no se actualiza en absoluto.
--   Los datos se agregan a la base de datos pero no se modifican.
--   Para las lecturas, se extrae un número bastante grande de filas de la base de datos, pero solo un pequeño subconjunto de columnas.
--   Las tablas son “wide,” lo que significa que contienen un gran número de columnas.
--   Las consultas son relativamente raras (generalmente cientos de consultas por servidor o menos por segundo).
--   Para consultas simples, se permiten latencias de alrededor de 50 ms.
--   Los valores de columna son bastante pequeños: números y cadenas cortas (por ejemplo, 60 bytes por URL).
--   Requiere un alto rendimiento al procesar una sola consulta (hasta miles de millones de filas por segundo por servidor).
--   Las transacciones no son necesarias.
--   Bajos requisitos para la coherencia de los datos.
--   Hay una tabla grande por consulta. Todas las mesas son pequeñas, excepto una.
--   Un resultado de consulta es significativamente menor que los datos de origen. En otras palabras, los datos se filtran o se agregan, por lo que el resultado se ajusta a la RAM de un solo servidor.
-
-Es fácil ver que el escenario OLAP es muy diferente de otros escenarios populares (como el acceso OLTP o Key-Value). Por lo tanto, no tiene sentido intentar usar OLTP o una base de datos de valor clave para procesar consultas analíticas si desea obtener un rendimiento decente. Por ejemplo, si intenta usar MongoDB o Redis para análisis, obtendrá un rendimiento muy bajo en comparación con las bases de datos OLAP.
-
-## Por qué las bases de datos orientadas a columnas funcionan mejor en el escenario OLAP {#why-column-oriented-databases-work-better-in-the-olap-scenario}
-
-Las bases de datos orientadas a columnas son más adecuadas para los escenarios OLAP: son al menos 100 veces más rápidas en el procesamiento de la mayoría de las consultas. Las razones se explican en detalle a continuación, pero el hecho es más fácil de demostrar visualmente:
-
-**DBMS orientado a filas**
-
-![Row-oriented](images/row-oriented.gif#)
-
-**DBMS orientado a columnas**
-
-![Column-oriented](images/column-oriented.gif#)
-
-Ver la diferencia?
-
-### Entrada/salida {#inputoutput}
-
-1.  Para una consulta analítica, solo es necesario leer un pequeño número de columnas de tabla. En una base de datos orientada a columnas, puede leer solo los datos que necesita. Por ejemplo, si necesita 5 columnas de 100, puede esperar una reducción de 20 veces en E/S.
-2.  Dado que los datos se leen en paquetes, es más fácil de comprimir. Los datos en columnas también son más fáciles de comprimir. Esto reduce aún más el volumen de E/S.
-3.  Debido a la reducción de E / S, más datos se ajustan a la memoria caché del sistema.
-
-Por ejemplo, la consulta “count the number of records for each advertising platform” requiere leer uno “advertising platform ID” columna, que ocupa 1 byte sin comprimir. Si la mayor parte del tráfico no proviene de plataformas publicitarias, puede esperar al menos una compresión de 10 veces de esta columna. Cuando se utiliza un algoritmo de compresión rápida, la descompresión de datos es posible a una velocidad de al menos varios gigabytes de datos sin comprimir por segundo. En otras palabras, esta consulta se puede procesar a una velocidad de aproximadamente varios miles de millones de filas por segundo en un único servidor. Esta velocidad se logra realmente en la práctica.
-
-### CPU {#cpu}
-
-Dado que la ejecución de una consulta requiere procesar un gran número de filas, ayuda enviar todas las operaciones para vectores completos en lugar de para filas separadas, o implementar el motor de consultas para que casi no haya costo de envío. Si no hace esto, con cualquier subsistema de disco medio decente, el intérprete de consultas inevitablemente detiene la CPU. Tiene sentido almacenar datos en columnas y procesarlos, cuando sea posible, por columnas.
-
-Hay dos formas de hacer esto:
-
-1.  Un vector motor. Todas las operaciones se escriben para vectores, en lugar de para valores separados. Esto significa que no necesita llamar a las operaciones con mucha frecuencia, y los costos de envío son insignificantes. El código de operación contiene un ciclo interno optimizado.
-
-2.  Generación de código. El código generado para la consulta tiene todas las llamadas indirectas.
-
-Esto no se hace en “normal” bases de datos, porque no tiene sentido cuando se ejecutan consultas simples. Sin embargo, hay excepciones. Por ejemplo, MemSQL utiliza la generación de código para reducir la latencia al procesar consultas SQL. (A modo de comparación, los DBMS analíticos requieren la optimización del rendimiento, no la latencia.)
-
-Tenga en cuenta que para la eficiencia de la CPU, el lenguaje de consulta debe ser declarativo (SQL o MDX), o al menos un vector (J, K). La consulta solo debe contener bucles implícitos, lo que permite la optimización.

-# Cliente de línea de comandos {#command-line-client}
-
-ClickHouse proporciona un cliente de línea de comandos nativo: `clickhouse-client`. El cliente admite opciones de línea de comandos y archivos de configuración. Para obtener más información, consulte [Configuración](#interfaces_cli_configuration).
-
-[Instalar](../getting-started/index.md) desde el `clickhouse-client` paquete y ejecútelo con el comando `clickhouse-client`.
-
-``` bash
-$ clickhouse-client
-ClickHouse client version 19.17.1.1579 (official build).
-Connecting to localhost:9000 as user default.
-Connected to ClickHouse server version 19.17.1 revision 54428.
-
-:)
-```
-
-Las diferentes versiones de cliente y servidor son compatibles entre sí, pero es posible que algunas funciones no estén disponibles en clientes anteriores. Se recomienda utilizar la misma versión del cliente que la aplicación de servidor. Cuando intenta usar un cliente de la versión anterior, entonces el servidor, `clickhouse-client` muestra el mensaje:
-
-      ClickHouse client version is older than ClickHouse server. It may lack support for new features.
-
-## Uso {#cli_usage}
-
-El cliente se puede utilizar en modo interactivo y no interactivo (por lotes). Para utilizar el modo por lotes, especifique el ‘query’ parámetro, o enviar datos a ‘stdin’ (verifica que ‘stdin’ no es un terminal), o ambos. Similar a la interfaz HTTP, cuando se utiliza el ‘query’ parámetro y el envío de datos a ‘stdin’ la solicitud es una concatenación de la ‘query’ parámetro, un avance de línea y los datos en ‘stdin’. Esto es conveniente para grandes consultas INSERT.
-
-Ejemplo de uso del cliente para insertar datos:
-
-``` bash
-$ echo -ne "1, 'some text', '2016-08-14 00:00:00'\n2, 'some more text', '2016-08-14 00:00:01'" | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
-
-$ cat <<_EOF | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
-3, 'some text', '2016-08-14 00:00:00'
-4, 'some more text', '2016-08-14 00:00:01'
-_EOF
-
-$ cat file.csv | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
-```
-
-En el modo por lotes, el formato de datos predeterminado es TabSeparated. Puede establecer el formato en la cláusula FORMAT de la consulta.
-
-De forma predeterminada, solo puede procesar una única consulta en modo por lotes. Para realizar múltiples consultas desde un “script,” utilizar el `--multiquery` parámetro. Esto funciona para todas las consultas excepto INSERT . Los resultados de la consulta se generan consecutivamente sin separadores adicionales. Del mismo modo, para procesar un gran número de consultas, puede ejecutar ‘clickhouse-client’ para cada consulta. Tenga en cuenta que puede tomar decenas de milisegundos para iniciar el ‘clickhouse-client’ programa.
-
-En el modo interactivo, obtiene una línea de comandos donde puede ingresar consultas.
-
-Si ‘multiline’ no se especifica (el valor predeterminado): Para ejecutar la consulta, pulse Intro. El punto y coma no es necesario al final de la consulta. Para introducir una consulta de varias líneas, introduzca una barra invertida `\` antes de la alimentación de línea. Después de presionar Enter, se le pedirá que ingrese la siguiente línea de la consulta.
-
-Si se especifica multilínea: Para ejecutar una consulta, finalícela con un punto y coma y presione Intro. Si se omitió el punto y coma al final de la línea ingresada, se le pedirá que ingrese la siguiente línea de la consulta.
-
-Solo se ejecuta una sola consulta, por lo que se ignora todo después del punto y coma.
-
-Puede especificar `\G` en lugar o después del punto y coma. Esto indica el formato vertical. En este formato, cada valor se imprime en una línea separada, lo cual es conveniente para tablas anchas. Esta característica inusual se agregó por compatibilidad con la CLI de MySQL.
-
-La línea de comandos se basa en ‘replxx’ (similar a ‘readline’). En otras palabras, utiliza los atajos de teclado familiares y mantiene un historial. La historia está escrita para `~/.clickhouse-client-history`.
-
-De forma predeterminada, el formato utilizado es PrettyCompact. Puede cambiar el formato en la cláusula FORMAT de la consulta o especificando `\G` al final de la consulta, utilizando el `--format` o `--vertical` en la línea de comandos, o utilizando el archivo de configuración del cliente.
-
-Para salir del cliente, presione Ctrl+D o introduzca una de las siguientes opciones en lugar de una consulta: “exit”, “quit”, “logout”, “exit;”, “quit;”, “logout;”, “q”, “Q”, “:q”
-
-Al procesar una consulta, el cliente muestra:
-
-1.  Progreso, que se actualiza no más de 10 veces por segundo (de forma predeterminada). Para consultas rápidas, es posible que el progreso no tenga tiempo para mostrarse.
-2.  La consulta con formato después del análisis, para la depuración.
-3.  El resultado en el formato especificado.
-4.  El número de líneas en el resultado, el tiempo transcurrido y la velocidad promedio de procesamiento de consultas.
-
-Puede cancelar una consulta larga presionando Ctrl + C. Sin embargo, aún tendrá que esperar un poco para que el servidor aborte la solicitud. No es posible cancelar una consulta en determinadas etapas. Si no espera y presiona Ctrl + C por segunda vez, el cliente saldrá.
-
-El cliente de línea de comandos permite pasar datos externos (tablas temporales externas) para consultar. Para obtener más información, consulte la sección “External data for query processing”.
-
-### Consultas con parámetros {#cli-queries-with-parameters}
-
-Puede crear una consulta con parámetros y pasarles valores desde la aplicación cliente. Esto permite evitar formatear consultas con valores dinámicos específicos en el lado del cliente. Por ejemplo:
-
-``` bash
-$ clickhouse-client --param_parName="[1, 2]"  -q "SELECT * FROM table WHERE a = {parName:Array(UInt16)}"
-```
-
-#### Sintaxis de consulta {#cli-queries-with-parameters-syntax}
-
-Formatee una consulta como de costumbre, luego coloque los valores que desea pasar de los parámetros de la aplicación a la consulta entre llaves en el siguiente formato:
-
-``` sql
-{<name>:<data type>}
-```
-
--   `name` — Placeholder identifier. In the console client it should be used in app parameters as `--param_<name> = value`.
--   `data type` — [Tipo de datos](../sql-reference/data-types/index.md) del valor del parámetro de la aplicación. Por ejemplo, una estructura de datos como `(integer, ('string', integer))` puede tener el `Tuple(UInt8, Tuple(String, UInt8))` tipo de datos (también puede usar otro [entero](../sql-reference/data-types/int-uint.md) tipo).
-
-#### Ejemplo {#example}
-
-``` bash
-$ clickhouse-client --param_tuple_in_tuple="(10, ('dt', 10))" -q "SELECT * FROM table WHERE val = {tuple_in_tuple:Tuple(UInt8, Tuple(String, UInt8))}"
-```
-
-## Configuración {#interfaces_cli_configuration}
-
-Puede pasar parámetros a `clickhouse-client` (todos los parámetros tienen un valor predeterminado) usando:
-
--   Desde la línea de comandos
-
-    Las opciones de la línea de comandos anulan los valores y valores predeterminados de los archivos de configuración.
-
--   Archivos de configuración.
-
-    Los valores de los archivos de configuración anulan los valores predeterminados.
-
-### Opciones de línea de comandos {#command-line-options}
-
--   `--host, -h` -– The server name, ‘localhost’ predeterminada. Puede utilizar el nombre o la dirección IPv4 o IPv6.
--   `--port` – The port to connect to. Default value: 9000. Note that the HTTP interface and the native interface use different ports.
--   `--user, -u` – The username. Default value: default.
--   `--password` – The password. Default value: empty string.
--   `--query, -q` – The query to process when using non-interactive mode.
--   `--database, -d` – Select the current default database. Default value: the current database from the server settings (‘default’ predeterminada).
--   `--multiline, -m` – If specified, allow multiline queries (do not send the query on Enter).
--   `--multiquery, -n` – If specified, allow processing multiple queries separated by semicolons.
--   `--format, -f` – Use the specified default format to output the result.
--   `--vertical, -E` – If specified, use the Vertical format by default to output the result. This is the same as ‘–format=Vertical’. En este formato, cada valor se imprime en una línea separada, lo que es útil cuando se muestran tablas anchas.
--   `--time, -t` – If specified, print the query execution time to ‘stderr’ en modo no interactivo.
--   `--stacktrace` – If specified, also print the stack trace if an exception occurs.
--   `--config-file` – The name of the configuration file.
--   `--secure` – If specified, will connect to server over secure connection.
--   `--param_<name>` — Value for a [consulta con parámetros](#cli-queries-with-parameters).
-
-### Archivos de configuración {#configuration_files}
-
-`clickhouse-client` utiliza el primer archivo existente de los siguientes:
-
--   Definido en el `--config-file` parámetro.
--   `./clickhouse-client.xml`
--   `~/.clickhouse-client/config.xml`
--   `/etc/clickhouse-client/config.xml`
-
-Ejemplo de un archivo de configuración:
-
-``` xml
-<config>
-    <user>username</user>
-    <password>password</password>
-    <secure>False</secure>
-</config>
-```

-# Formatos para datos de entrada y salida {#formats}
-
-ClickHouse puede aceptar y devolver datos en varios formatos. Se puede utilizar un formato admitido para la entrada para analizar los datos proporcionados a `INSERT`s, para llevar a cabo `SELECT`s de una tabla respaldada por archivos como File, URL o HDFS, o para leer un diccionario externo. Se puede utilizar un formato compatible con la salida para organizar el
-resultados de un `SELECT`, y realizar `INSERT`s en una tabla respaldada por archivos.
-
-Los formatos soportados son:
-

-## TabSeparated {#tabseparated}
-
-En el formato TabSeparated, los datos se escriben por fila. Cada fila contiene valores separados por pestañas. Cada valor es seguido por una ficha, excepto el último valor de la fila, que es seguido por un avance de línea. Estrictamente las fuentes de línea Unix se asumen en todas partes. La última fila también debe contener un avance de línea al final. Los valores se escriben en formato de texto, sin incluir comillas y con caracteres especiales escapados.
-
-Este formato también está disponible bajo el nombre `TSV`.
-
-El `TabSeparated` es conveniente para procesar datos utilizando programas y scripts personalizados. Se usa de forma predeterminada en la interfaz HTTP y en el modo por lotes del cliente de línea de comandos. Este formato también permite transferir datos entre diferentes DBMS. Por ejemplo, puede obtener un volcado de MySQL y subirlo a ClickHouse, o viceversa.
-
-El `TabSeparated` el formato admite la salida de valores totales (cuando se usa WITH TOTALS) y valores extremos (cuando ‘extremes’ se establece en 1). En estos casos, los valores totales y los extremos se emiten después de los datos principales. El resultado principal, los valores totales y los extremos están separados entre sí por una línea vacía. Ejemplo:
-
-``` sql
-SELECT EventDate, count() AS c FROM test.hits GROUP BY EventDate WITH TOTALS ORDER BY EventDate FORMAT TabSeparated``
-```

-### Formato de datos {#data-formatting}
-
-Los números enteros se escriben en forma decimal. Los números pueden contener un extra “+” carácter al principio (ignorado al analizar y no grabado al formatear). Los números no negativos no pueden contener el signo negativo. Al leer, se permite analizar una cadena vacía como cero, o (para tipos con signo) una cadena que consiste en solo un signo menos como cero. Los números que no encajan en el tipo de datos correspondiente se pueden analizar como un número diferente, sin un mensaje de error.
-
-Los números de punto flotante se escriben en forma decimal. El punto se usa como separador decimal. Las entradas exponenciales son compatibles, al igual que ‘inf’, ‘+inf’, ‘-inf’, y ‘nan’. Una entrada de números de coma flotante puede comenzar o terminar con un punto decimal.
-Durante el formateo, la precisión puede perderse en los números de coma flotante.
-Durante el análisis, no es estrictamente necesario leer el número representable de la máquina más cercano.
-
-Las fechas se escriben en formato AAAA-MM-DD y se analizan en el mismo formato, pero con los caracteres como separadores.
-Las fechas con horas se escriben en el formato `YYYY-MM-DD hh:mm:ss` y analizado en el mismo formato, pero con cualquier carácter como separadores.
-Todo esto ocurre en la zona horaria del sistema en el momento en que se inicia el cliente o servidor (dependiendo de cuál de ellos formatea los datos). Para fechas con horarios, no se especifica el horario de verano. Por lo tanto, si un volcado tiene tiempos durante el horario de verano, el volcado no coincide inequívocamente con los datos, y el análisis seleccionará una de las dos veces.
-Durante una operación de lectura, las fechas incorrectas y las fechas con horas se pueden analizar con desbordamiento natural o como fechas y horas nulas, sin un mensaje de error.
-
-Como excepción, el análisis de fechas con horas también se admite en el formato de marca de tiempo Unix, si consta de exactamente 10 dígitos decimales. El resultado no depende de la zona horaria. Los formatos AAAA-MM-DD hh:mm:ss y NNNNNNNNNN se diferencian automáticamente.
-
-Las cadenas se generan con caracteres especiales de escape de barra invertida. Las siguientes secuencias de escape se utilizan para la salida: `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\'`, `\\`. El análisis también admite las secuencias `\a`, `\v`, y `\xHH` (secuencias de escape hexagonales) y cualquier `\c` secuencias, donde `c` es cualquier carácter (estas secuencias se convierten en `c`). Por lo tanto, la lectura de datos admite formatos donde un avance de línea se puede escribir como `\n` o `\` o como un avance de línea. Por ejemplo, la cadena `Hello world` con un avance de línea entre las palabras en lugar de espacio se puede analizar en cualquiera de las siguientes variaciones:
-
-``` text
-Hello\nworld
-
-Hello\
-world
-```
-
-La segunda variante es compatible porque MySQL la usa al escribir volcados separados por tabuladores.
-
-El conjunto mínimo de caracteres que debe escapar al pasar datos en formato TabSeparated: tabulación, salto de línea (LF) y barra invertida.
-
-Solo se escapa un pequeño conjunto de símbolos. Puede tropezar fácilmente con un valor de cadena que su terminal arruinará en la salida.
-
-Las matrices se escriben como una lista de valores separados por comas entre corchetes. Los elementos numéricos de la matriz tienen el formato normal. `Date` y `DateTime` están escritos entre comillas simples. Las cadenas se escriben entre comillas simples con las mismas reglas de escape que las anteriores.
-
-[NULL](../sql-reference/syntax.md) se formatea como `\N`.
-
-Cada elemento de [Anidar](../sql-reference/data-types/nested-data-structures/nested.md) estructuras se representa como una matriz.
-
-Por ejemplo:
-
-``` sql
-CREATE TABLE nestedt
-(
-    `id` UInt8,
-    `aux` Nested(
-        a UInt8,
-        b String
-    )
-)
-ENGINE = TinyLog
-```
-
-``` sql
-INSERT INTO nestedt Values ( 1, [1], ['a'])
-```
-
-``` sql
-SELECT * FROM nestedt FORMAT TSV
-```
-
-``` text
-1  [1]    ['a']
-```
-
-## TabSeparatedRaw {#tabseparatedraw}
-
-Difiere de `TabSeparated` formato en que las filas se escriben sin escapar.
-Este formato solo es apropiado para generar un resultado de consulta, pero no para analizar (recuperar datos para insertar en una tabla).
-
-Este formato también está disponible bajo el nombre `TSVRaw`.
-
-## TabSeparatedWithNames {#tabseparatedwithnames}
-
-Difiere de la `TabSeparated` formato en que los nombres de columna se escriben en la primera fila.
-Durante el análisis, la primera fila se ignora por completo. No puede usar nombres de columna para determinar su posición o para comprobar su corrección.
-(Se puede agregar soporte para analizar la fila de encabezado en el futuro.)
-
-Este formato también está disponible bajo el nombre `TSVWithNames`.
-
-## TabSeparatedWithNamesAndTypes {#tabseparatedwithnamesandtypes}
-
-Difiere de la `TabSeparated` formato en que los nombres de columna se escriben en la primera fila, mientras que los tipos de columna están en la segunda fila.
-Durante el análisis, la primera y la segunda filas se ignoran por completo.
-
-Este formato también está disponible bajo el nombre `TSVWithNamesAndTypes`.
-
-## Plantilla {#format-template}
-
-Este formato permite especificar una cadena de formato personalizado con marcadores de posición para los valores con una regla de escape especificada.
-
-Utiliza la configuración `format_template_resultset`, `format_template_row`, `format_template_rows_between_delimiter` and some settings of other formats (e.g. `output_format_json_quote_64bit_integers` cuando se utiliza `JSON` escapar, ver más)
-
-Configuración `format_template_row` especifica la ruta de acceso al archivo, que contiene una cadena de formato para las filas con la siguiente sintaxis:
-
-`delimiter_1${column_1:serializeAs_1}delimiter_2${column_2:serializeAs_2} ... delimiter_N`,
-
-donde `delimiter_i` es un delimitador entre valores (`$` símbolo se puede escapar como `$$`),
-`column_i` es un nombre o índice de una columna cuyos valores se deben seleccionar o insertar (si está vacío, se omitirá la columna),
-`serializeAs_i` es una regla de escape para los valores de columna. Se admiten las siguientes reglas de escape:
-
--   `CSV`, `JSON`, `XML` (similar a los formatos de los mismos nombres)
--   `Escaped` (similar a `TSV`)
--   `Quoted` (similar a `Values`)
--   `Raw` (sin escapar, de manera similar a `TSVRaw`)
--   `None` (sin regla de escape, ver más)
-
-Si se omite una regla de escape, entonces `None` se utilizará. `XML` y `Raw` son adecuados sólo para la salida.
-
-Entonces, para la siguiente cadena de formato:
-
-      `Search phrase: ${SearchPhrase:Quoted}, count: ${c:Escaped}, ad price: $$${price:JSON};`
-
-los valores de `SearchPhrase`, `c` y `price` columnas, que se escapan como `Quoted`, `Escaped` y `JSON` se imprimirá (para seleccionar) o se esperará (para insertar) entre `Search phrase:`, `, count:`, `, ad price: $` y `;` delimitadores respectivamente. Por ejemplo:
-
-`Search phrase: 'bathroom interior design', count: 2166, ad price: $3;`
-
-El `format_template_rows_between_delimiter` setting especifica el delimitador entre filas, que se imprime (o se espera) después de cada fila, excepto la última (`\n` predeterminada)
-
-Configuración `format_template_resultset` especifica la ruta al archivo, que contiene una cadena de formato para el conjunto de resultados. La cadena de formato para el conjunto de resultados tiene la misma sintaxis que una cadena de formato para la fila y permite especificar un prefijo, un sufijo y una forma de imprimir información adicional. Contiene los siguientes marcadores de posición en lugar de nombres de columna:
-
--   `data` son las filas con datos en `format_template_row` formato, separados por `format_template_rows_between_delimiter`. Este marcador de posición debe ser el primer marcador de posición en la cadena de formato.
--   `totals` es la fila con valores totales en `format_template_row` formato (cuando se usa WITH TOTALS)
--   `min` es la fila con valores mínimos en `format_template_row` formato (cuando los extremos se establecen en 1)
--   `max` es la fila con valores máximos en `format_template_row` formato (cuando los extremos se establecen en 1)
--   `rows` es el número total de filas de salida
--   `rows_before_limit` es el número mínimo de filas que habría habido sin LIMIT. Salida solo si la consulta contiene LIMIT. Si la consulta contiene GROUP BY, rows_before_limit_at_least es el número exacto de filas que habría habido sin un LIMIT .
--   `time` es el tiempo de ejecución de la solicitud en segundos
--   `rows_read` es el número de filas que se ha leído
--   `bytes_read` es el número de bytes (sin comprimir) que se ha leído
-
-Marcador `data`, `totals`, `min` y `max` no debe tener una regla de escape especificada (o `None` debe especificarse explícitamente). Los marcadores de posición restantes pueden tener cualquier regla de escape especificada.
-Si el `format_template_resultset` valor es una cadena vacía, `${data}` se utiliza como valor predeterminado.
-Para el formato de consultas de inserción permite omitir algunas columnas o algunos campos si prefijo o sufijo (ver ejemplo).
-
-Seleccionar ejemplo:
-
-``` sql
-SELECT SearchPhrase, count() AS c FROM test.hits GROUP BY SearchPhrase ORDER BY c DESC LIMIT 5 FORMAT Template SETTINGS
-format_template_resultset = '/some/path/resultset.format', format_template_row = '/some/path/row.format', format_template_rows_between_delimiter = '\n    '
-```

-
-Insertar ejemplo:
-
-``` text
-Some header
-Page views: 5, User id: 4324182021466249494, Useless field: hello, Duration: 146, Sign: -1
-Page views: 6, User id: 4324182021466249494, Useless field: world, Duration: 185, Sign: 1
-Total rows: 2
-```
-
-``` sql
-INSERT INTO UserActivity FORMAT Template SETTINGS
-format_template_resultset = '/some/path/resultset.format', format_template_row = '/some/path/row.format'
-```
-
-`/some/path/resultset.format`:
-
-``` text
-Some header\n${data}\nTotal rows: ${:CSV}\n
-```
-
-`/some/path/row.format`:
-
-``` text
-Page views: ${PageViews:CSV}, User id: ${UserID:CSV}, Useless field: ${:CSV}, Duration: ${Duration:CSV}, Sign: ${Sign:CSV}
-```
-
-`PageViews`, `UserID`, `Duration` y `Sign` dentro de los marcadores de posición son nombres de columnas en la tabla. Valores después `Useless field` en filas y después `\nTotal rows:` en el sufijo será ignorado.
-Todos los delimitadores de los datos de entrada deben ser estrictamente iguales a los delimitadores de las cadenas de formato especificadas.
-
-## TemplateIgnoreSpaces {#templateignorespaces}
-
-Este formato es adecuado sólo para la entrada.
-Similar a `Template`, pero omite caracteres de espacio en blanco entre delimitadores y valores en la secuencia de entrada. Sin embargo, si las cadenas de formato contienen caracteres de espacio en blanco, se esperarán estos caracteres en la secuencia de entrada. También permite especificar marcadores de posición vacíos (`${}` o `${:None}`) para dividir algún delimitador en partes separadas para ignorar los espacios entre ellos. Dichos marcadores de posición se usan solo para omitir caracteres de espacio en blanco.
-Es posible leer `JSON` usando este formato, si los valores de las columnas tienen el mismo orden en todas las filas. Por ejemplo, la siguiente solicitud se puede utilizar para insertar datos del ejemplo de salida de formato [JSON](#json):
-
-``` sql
-INSERT INTO table_name FORMAT TemplateIgnoreSpaces SETTINGS
-format_template_resultset = '/some/path/resultset.format', format_template_row = '/some/path/row.format', format_template_rows_between_delimiter = ','
-```
-
-`/some/path/resultset.format`:
-
-``` text
-{${}"meta"${}:${:JSON},${}"data"${}:${}[${data}]${},${}"totals"${}:${:JSON},${}"extremes"${}:${:JSON},${}"rows"${}:${:JSON},${}"rows_before_limit_at_least"${}:${:JSON}${}}
-```
-
-`/some/path/row.format`:
-
-``` text
-{${}"SearchPhrase"${}:${}${phrase:JSON}${},${}"c"${}:${}${cnt:JSON}${}}
-```
-
-## TSKV {#tskv}
-
-Similar a TabSeparated , pero genera un valor en formato name=value . Los nombres se escapan de la misma manera que en el formato TabSeparated, y el símbolo = también se escapa.
-
-``` text
-SearchPhrase=   count()=8267016
-SearchPhrase=bathroom interior design    count()=2166
-SearchPhrase=yandex     count()=1655
-SearchPhrase=2014 spring fashion    count()=1549
-SearchPhrase=freeform photos       count()=1480
-SearchPhrase=angelina jolie    count()=1245
-SearchPhrase=omsk       count()=1112
-SearchPhrase=photos of dog breeds    count()=1091
-SearchPhrase=curtain designs        count()=1064
-SearchPhrase=baku       count()=1000
-```
-
-[NULL](../sql-reference/syntax.md) se formatea como `\N`.
-
-``` sql
-SELECT * FROM t_null FORMAT TSKV
-```
-
-``` text
-x=1    y=\N
-```
-
-Cuando hay una gran cantidad de columnas pequeñas, este formato no es efectivo y generalmente no hay razón para usarlo. Sin embargo, no es peor que JSONEachRow en términos de eficiencia.
-
-Both data output and parsing are supported in this format. For parsing, any order is supported for the values of different columns. It is acceptable for some values to be omitted – they are treated as equal to their default values. In this case, zeros and blank rows are used as default values. Complex values that could be specified in the table are not supported as defaults.
-
-El análisis permite la presencia del campo adicional `tskv` sin el signo igual o un valor. Este campo se ignora.
-
-## CSV {#csv}
-
-Formato de valores separados por comas ([RFC](https://tools.ietf.org/html/rfc4180)).
-
-Al formatear, las filas están encerradas en comillas dobles. Una comilla doble dentro de una cadena se genera como dos comillas dobles en una fila. No hay otras reglas para escapar de los personajes. Fecha y fecha-hora están encerrados en comillas dobles. Los números se emiten sin comillas. Los valores están separados por un carácter delimitador, que es `,` predeterminada. El carácter delimitador se define en la configuración [Formato_csv_delimiter](../operations/settings/settings.md#settings-format_csv_delimiter). Las filas se separan usando el avance de línea Unix (LF). Las matrices se serializan en CSV de la siguiente manera: primero, la matriz se serializa en una cadena como en el formato TabSeparated, y luego la cadena resultante se envía a CSV en comillas dobles. Las tuplas en formato CSV se serializan como columnas separadas (es decir, se pierde su anidamiento en la tupla).
-
-``` bash
-$ clickhouse-client --format_csv_delimiter="|" --query="INSERT INTO test.csv FORMAT CSV" < data.csv
-```
-
-\*De forma predeterminada, el delimitador es `,`. Ver el [Formato_csv_delimiter](../operations/settings/settings.md#settings-format_csv_delimiter) para obtener más información.
-
-Al analizar, todos los valores se pueden analizar con o sin comillas. Ambas comillas dobles y simples son compatibles. Las filas también se pueden organizar sin comillas. En este caso, se analizan hasta el carácter delimitador o el avance de línea (CR o LF). En violación del RFC, al analizar filas sin comillas, se ignoran los espacios y pestañas iniciales y finales. Para el avance de línea, se admiten los tipos Unix (LF), Windows (CR LF) y Mac OS Classic (CR LF).
-
-Los valores de entrada vacíos sin comillas se sustituyen por valores predeterminados para las columnas respectivas, si
-[Entrada_format_defaults_for_omitted_fields](../operations/settings/settings.md#session_settings-input_format_defaults_for_omitted_fields)
-está habilitado.
-
-`NULL` se formatea como `\N` o `NULL` o una cadena vacía sin comillas (consulte la configuración [input_format_csv_unquoted_null_literal_as_null](../operations/settings/settings.md#settings-input_format_csv_unquoted_null_literal_as_null) y [Entrada_format_defaults_for_omitted_fields](../operations/settings/settings.md#session_settings-input_format_defaults_for_omitted_fields)).
-
-El formato CSV admite la salida de totales y extremos de la misma manera que `TabSeparated`.
-
-## CSVWithNames {#csvwithnames}
-
-También imprime la fila del encabezado, similar a `TabSeparatedWithNames`.
-
-## CustomSeparated {#format-customseparated}
-
-Similar a [Plantilla](#format-template), pero imprime o lee todas las columnas y usa la regla de escape de la configuración `format_custom_escaping_rule` y delimitadores desde la configuración `format_custom_field_delimiter`, `format_custom_row_before_delimiter`, `format_custom_row_after_delimiter`, `format_custom_row_between_delimiter`, `format_custom_result_before_delimiter` y `format_custom_result_after_delimiter`, no de cadenas de formato.
-También hay `CustomSeparatedIgnoreSpaces` formato, que es similar a `TemplateIgnoreSpaces`.
-
-## JSON {#json}
-
-Salida de datos en formato JSON. Además de las tablas de datos, también genera nombres y tipos de columnas, junto con información adicional: el número total de filas de salida y el número de filas que podrían haberse generado si no hubiera un LIMIT . Ejemplo:
-
-``` sql
-SELECT SearchPhrase, count() AS c FROM test.hits GROUP BY SearchPhrase WITH TOTALS ORDER BY c DESC LIMIT 5 FORMAT JSON
-```
-
-``` json
-{
-        "meta":
-        [
-                {

-}
-```
-
-El JSON es compatible con JavaScript. Para garantizar esto, algunos caracteres se escapan adicionalmente: la barra inclinada `/` se escapa como `\/`; saltos de línea alternativos `U+2028` y `U+2029`, que rompen algunos navegadores, se escapan como `\uXXXX`. Los caracteres de control ASCII se escapan: retroceso, avance de formulario, avance de línea, retorno de carro y tabulación horizontal se reemplazan con `\b`, `\f`, `\n`, `\r`, `\t` , así como los bytes restantes en el rango 00-1F usando `\uXXXX` sequences. Invalid UTF-8 sequences are changed to the replacement character � so the output text will consist of valid UTF-8 sequences. For compatibility with JavaScript, Int64 and UInt64 integers are enclosed in double-quotes by default. To remove the quotes, you can set the configuration parameter [output_format_json_quote_64bit_integers](../operations/settings/settings.md#session_settings-output_format_json_quote_64bit_integers) a 0.
-
-`rows` – The total number of output rows.
-
-`rows_before_limit_at_least` El número mínimo de filas habría sido sin LIMIT . Salida solo si la consulta contiene LIMIT.
-Si la consulta contiene GROUP BY, rows_before_limit_at_least es el número exacto de filas que habría habido sin un LIMIT .
-
-`totals` – Total values (when using WITH TOTALS).
-
-`extremes` – Extreme values (when extremes are set to 1).
-
-Este formato solo es apropiado para generar un resultado de consulta, pero no para analizar (recuperar datos para insertar en una tabla).
-
-Soporta ClickHouse [NULL](../sql-reference/syntax.md), que se muestra como `null` en la salida JSON.
-
-Ver también el [JSONEachRow](#jsoneachrow) formato.
-
-## JSONCompact {#jsoncompact}
-
-Difiere de JSON solo en que las filas de datos se generan en matrices, no en objetos.
-
-Ejemplo:
-
-``` json
-{
-        "meta":
-        [
-                {
-                        "name": "SearchPhrase",
-                        "type": "String"
-                },
-                {
-                        "name": "c",

-
-Este formato solo es apropiado para generar un resultado de consulta, pero no para analizar (recuperar datos para insertar en una tabla).
-Ver también el `JSONEachRow` formato.
-
-## JSONEachRow {#jsoneachrow}
-
-Al usar este formato, ClickHouse genera filas como objetos JSON separados, delimitados por nuevas líneas, pero los datos en su conjunto no son JSON válidos.
-
-``` json
-{"SearchPhrase":"curtain designs","count()":"1064"}
-{"SearchPhrase":"baku","count()":"1000"}
-{"SearchPhrase":"","count()":"8267016"}
-```
-
-Al insertar los datos, debe proporcionar un objeto JSON independiente para cada fila.
-
-### Insertar datos {#inserting-data}
-
-``` sql
-INSERT INTO UserActivity FORMAT JSONEachRow {"PageViews":5, "UserID":"4324182021466249494", "Duration":146,"Sign":-1} {"UserID":"4324182021466249494","PageViews":6,"Duration":185,"Sign":1}
-```
-
-ClickHouse permite:
-
--   Cualquier orden de pares clave-valor en el objeto.
--   Omitiendo algunos valores.
-
-ClickHouse ignora los espacios entre los elementos y las comas después de los objetos. Puede pasar todos los objetos en una línea. No tiene que separarlos con saltos de línea.
-
-**Procesamiento de valores omitidos**
-
-ClickHouse sustituye los valores omitidos por los valores predeterminados para el [tipos de datos](../sql-reference/data-types/index.md).
-
-Si `DEFAULT expr` se especifica, ClickHouse utiliza diferentes reglas de sustitución dependiendo de la [Entrada_format_defaults_for_omitted_fields](../operations/settings/settings.md#session_settings-input_format_defaults_for_omitted_fields) configuración.
-
-Considere la siguiente tabla:
-
-``` sql
-CREATE TABLE IF NOT EXISTS example_table
-(
-    x UInt32,
-    a DEFAULT x * 2
-) ENGINE = Memory;
-```
-
--   Si `input_format_defaults_for_omitted_fields = 0`, entonces el valor predeterminado para `x` y `a` igual `0` (como el valor predeterminado para el `UInt32` tipo de datos).
--   Si `input_format_defaults_for_omitted_fields = 1`, entonces el valor predeterminado para `x` igual `0` pero el valor predeterminado de `a` igual `x * 2`.
-
-!!! note "Advertencia"
-    Al insertar datos con `insert_sample_with_metadata = 1`, ClickHouse consume más recursos computacionales, en comparación con la inserción con `insert_sample_with_metadata = 0`.
-
-### Selección de datos {#selecting-data}
-
-Considere el `UserActivity` tabla como un ejemplo:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Consulta `SELECT * FROM UserActivity FORMAT JSONEachRow` devoluciones:
-
-``` text
-{"UserID":"4324182021466249494","PageViews":5,"Duration":146,"Sign":-1}
-{"UserID":"4324182021466249494","PageViews":6,"Duration":185,"Sign":1}
-```
-
-A diferencia de la [JSON](#json) formato, no hay sustitución de secuencias UTF-8 no válidas. Los valores se escapan de la misma manera que para `JSON`.
-
-!!! note "Nota"
-    Cualquier conjunto de bytes se puede generar en las cadenas. Utilice el `JSONEachRow` si está seguro de que los datos de la tabla se pueden formatear como JSON sin perder ninguna información.
-
-### Uso de estructuras anidadas {#jsoneachrow-nested}
-
-Si tienes una mesa con [Anidar](../sql-reference/data-types/nested-data-structures/nested.md) columnas de tipo de datos, puede insertar datos JSON con la misma estructura. Habilite esta función con el [Entrada_format_import_nested_json](../operations/settings/settings.md#settings-input_format_import_nested_json) configuración.
-
-Por ejemplo, considere la siguiente tabla:
-
-``` sql
-CREATE TABLE json_each_row_nested (n Nested (s String, i Int32) ) ENGINE = Memory
-```
-
-Como se puede ver en el `Nested` descripción del tipo de datos, ClickHouse trata cada componente de la estructura anidada como una columna separada (`n.s` y `n.i` para nuestra mesa). Puede insertar datos de la siguiente manera:
-
-``` sql
-INSERT INTO json_each_row_nested FORMAT JSONEachRow {"n.s": ["abc", "def"], "n.i": [1, 23]}
-```
-
-Para insertar datos como un objeto JSON jerárquico, establezca [input_format_import_nested_json=1](../operations/settings/settings.md#settings-input_format_import_nested_json).
-
-``` json
-{
-    "n": {
-        "s": ["abc", "def"],
-        "i": [1, 23]
-    }
-}
-```
-
-Sin esta configuración, ClickHouse produce una excepción.
-
-``` sql
-SELECT name, value FROM system.settings WHERE name = 'input_format_import_nested_json'
-```
-
-``` text
-┌─name────────────────────────────┬─value─┐
-│ input_format_import_nested_json │ 0     │
-└─────────────────────────────────┴───────┘
-```
-
-``` sql
-INSERT INTO json_each_row_nested FORMAT JSONEachRow {"n": {"s": ["abc", "def"], "i": [1, 23]}}
-```
-
-``` text
-Code: 117. DB::Exception: Unknown field found while parsing JSONEachRow format: n: (at row 1)
-```
-
-``` sql
-SET input_format_import_nested_json=1
-INSERT INTO json_each_row_nested FORMAT JSONEachRow {"n": {"s": ["abc", "def"], "i": [1, 23]}}
-SELECT * FROM json_each_row_nested
-```
-
-``` text
-┌─n.s───────────┬─n.i────┐
-│ ['abc','def'] │ [1,23] │
-└───────────────┴────────┘
-```
-
-## Nativo {#native}
-
-El formato más eficiente. Los datos son escritos y leídos por bloques en formato binario. Para cada bloque, el número de filas, número de columnas, nombres y tipos de columnas y partes de columnas de este bloque se registran una tras otra. En otras palabras, este formato es “columnar” – it doesn't convert columns to rows. This is the format used in the native interface for interaction between servers, for using the command-line client, and for C++ clients.
-
-Puede utilizar este formato para generar rápidamente volcados que sólo pueden ser leídos por el DBMS de ClickHouse. No tiene sentido trabajar con este formato usted mismo.
-
-## Nulo {#null}
-
-Nada es salida. Sin embargo, la consulta se procesa y, cuando se utiliza el cliente de línea de comandos, los datos se transmiten al cliente. Esto se usa para pruebas, incluidas las pruebas de rendimiento.
-Obviamente, este formato solo es apropiado para la salida, no para el análisis.
-
-## Bastante {#pretty}
-
-Salidas de datos como tablas de arte Unicode, también utilizando secuencias de escape ANSI para establecer colores en el terminal.
-Se dibuja una cuadrícula completa de la tabla, y cada fila ocupa dos líneas en la terminal.
-Cada bloque de resultados se muestra como una tabla separada. Esto es necesario para que los bloques se puedan generar sin resultados de almacenamiento en búfer (el almacenamiento en búfer sería necesario para calcular previamente el ancho visible de todos los valores).
-
-[NULL](../sql-reference/syntax.md) se emite como `ᴺᵁᴸᴸ`.
-
-Ejemplo (mostrado para el [PrettyCompact](#prettycompact) formato):
-
-``` sql
-SELECT * FROM t_null
-```
-
-``` text
-┌─x─┬────y─┐
-│ 1 │ ᴺᵁᴸᴸ │
-└───┴──────┘
-```
-
-Las filas no se escapan en formatos Pretty \*. Se muestra un ejemplo para el [PrettyCompact](#prettycompact) formato:
-
-``` sql
-SELECT 'String with \'quotes\' and \t character' AS Escaping_test
-```
-
-``` text
-┌─Escaping_test────────────────────────┐
-│ String with 'quotes' and      character │
-└──────────────────────────────────────┘
-```
-
-Para evitar volcar demasiados datos al terminal, solo se imprimen las primeras 10.000 filas. Si el número de filas es mayor o igual que 10.000, el mensaje “Showed first 10 000” se imprime.
-Este formato solo es apropiado para generar un resultado de consulta, pero no para analizar (recuperar datos para insertar en una tabla).
-
-El formato Pretty admite la salida de valores totales (cuando se usa WITH TOTALS) y extremos (cuando ‘extremes’ se establece en 1). En estos casos, los valores totales y los valores extremos se generan después de los datos principales, en tablas separadas. Ejemplo (mostrado para el [PrettyCompact](#prettycompact) formato):
-
-``` sql
-SELECT EventDate, count() AS c FROM test.hits GROUP BY EventDate WITH TOTALS ORDER BY EventDate FORMAT PrettyCompact
-```
-
-``` text
-┌──EventDate─┬───────c─┐
-│ 2014-03-17 │ 1406958 │
-│ 2014-03-18 │ 1383658 │

-
-Totals:

-
-Extremes:

-└────────────┴─────────┘
-```
-
-## PrettyCompact {#prettycompact}
-
-Difiere de [Bastante](#pretty) en que la cuadrícula se dibuja entre filas y el resultado es más compacto.
-Este formato se usa de forma predeterminada en el cliente de línea de comandos en modo interactivo.
-
-## PrettyCompactMonoBlock {#prettycompactmonoblock}
-
-Difiere de [PrettyCompact](#prettycompact) en que hasta 10,000 filas se almacenan en búfer, luego se salen como una sola tabla, no por bloques.
-
-## PrettyNoEscapes {#prettynoescapes}
-
-Difiere de Pretty en que las secuencias de escape ANSI no se usan. Esto es necesario para mostrar este formato en un navegador, así como para usar el ‘watch’ utilidad de línea de comandos.
-
-Ejemplo:
-
-``` bash
-$ watch -n1 "clickhouse-client --query='SELECT event, value FROM system.events FORMAT PrettyCompactNoEscapes'"
-```
-
-Puede usar la interfaz HTTP para mostrar en el navegador.
-
-### PrettyCompactNoEscapes {#prettycompactnoescapes}
-
-Lo mismo que el ajuste anterior.
-
-### PrettySpaceNoEscapes {#prettyspacenoescapes}
-
-Lo mismo que el ajuste anterior.
-
-## Bienvenido a WordPress {#prettyspace}
-
-Difiere de [PrettyCompact](#prettycompact) en ese espacio en blanco (caracteres de espacio) se usa en lugar de la cuadrícula.
-
-## RowBinary {#rowbinary}
-
-Formatea y analiza datos por fila en formato binario. Las filas y los valores se enumeran consecutivamente, sin separadores.
-Este formato es menos eficiente que el formato nativo, ya que está basado en filas.
-
-Los integradores usan una representación little-endian de longitud fija. Por ejemplo, UInt64 usa 8 bytes.
-DateTime se representa como UInt32 que contiene la marca de tiempo Unix como el valor.
-Date se representa como un objeto UInt16 que contiene el número de días desde 1970-01-01 como el valor.
-La cadena se representa como una longitud varint (sin signo [LEB128](https://en.wikipedia.org/wiki/LEB128)), seguido de los bytes de la cadena.
-FixedString se representa simplemente como una secuencia de bytes.
-
-La matriz se representa como una longitud varint (sin signo [LEB128](https://en.wikipedia.org/wiki/LEB128)), seguido de elementos sucesivos de la matriz.
-
-Para [NULL](../sql-reference/syntax.md#null-literal) soporte, se añade un byte adicional que contiene 1 o 0 antes de cada [NULL](../sql-reference/data-types/nullable.md) valor. Si 1, entonces el valor es `NULL` y este byte se interpreta como un valor separado. Si es 0, el valor después del byte no es `NULL`.
-
-## RowBinaryWithNamesAndTypes {#rowbinarywithnamesandtypes}
-
-Similar a [RowBinary](#rowbinary), pero con encabezado añadido:
-
--   [LEB128](https://en.wikipedia.org/wiki/LEB128)-número codificado de columnas (N)
--   N `String`s especificando nombres de columna
--   N `String`s especificando tipos de columna
-
-## Valor {#data-format-values}
-
-Imprime cada fila entre paréntesis. Las filas están separadas por comas. No hay coma después de la última fila. Los valores dentro de los corchetes también están separados por comas. Los números se emiten en formato decimal sin comillas. Las matrices se emiten entre corchetes. Las cadenas, fechas y fechas con horas se generan entre comillas. Las reglas de escape y el análisis son similares a las [TabSeparated](#tabseparated) formato. Durante el formateo, los espacios adicionales no se insertan, pero durante el análisis, se permiten y omiten (excepto los espacios dentro de los valores de la matriz, que no están permitidos). [NULL](../sql-reference/syntax.md) se representa como `NULL`.
-
-The minimum set of characters that you need to escape when passing data in Values ​​format: single quotes and backslashes.
-
-Este es el formato que se utiliza en `INSERT INTO t VALUES ...`, pero también puede usarlo para formatear los resultados de la consulta.
-
-Ver también: [input_format_values_interpret_expressions](../operations/settings/settings.md#settings-input_format_values_interpret_expressions) y [input_format_values_deduce_templates_of_expressions](../operations/settings/settings.md#settings-input_format_values_deduce_templates_of_expressions) configuración.
-
-## Vertical {#vertical}
-
-Imprime cada valor en una línea independiente con el nombre de columna especificado. Este formato es conveniente para imprimir solo una o varias filas si cada fila consta de un gran número de columnas.
-
-[NULL](../sql-reference/syntax.md) se emite como `ᴺᵁᴸᴸ`.
-
-Ejemplo:
-
-``` sql
-SELECT * FROM t_null FORMAT Vertical
-```
-
-``` text
-Row 1:
-──────
-x: 1
-y: ᴺᵁᴸᴸ
-```
-
-Las filas no se escapan en formato vertical:
-
-``` sql
-SELECT 'string with \'quotes\' and \t with some special \n characters' AS test FORMAT Vertical
-```
-
-``` text
-Row 1:
-──────
-test: string with 'quotes' and      with some special
- characters
-```
-
-Este formato solo es apropiado para generar un resultado de consulta, pero no para analizar (recuperar datos para insertar en una tabla).
-
-## VerticalRaw {#verticalraw}
-
-Similar a [Vertical](#vertical), pero con escapar deshabilitado. Este formato solo es adecuado para generar resultados de consultas, no para analizar (recibir datos e insertarlos en la tabla).
-
-## XML {#xml}
-
-El formato XML es adecuado solo para la salida, no para el análisis. Ejemplo:
-
-``` xml
-<?xml version='1.0' encoding='UTF-8' ?>
-<result>
-        <meta>
-                <columns>
-                        <column>
-                                <name>SearchPhrase</name>
-                                <type>String</type>
-                        </column>
-                        <column>
-                                <name>count()</name>
-                                <type>UInt64</type>
-                        </column>
-                </columns>

-                </row>
-                <row>
-                        <SearchPhrase>omsk</SearchPhrase>
-                        <field>1112</field>
-                </row>
-                <row>
-                        <SearchPhrase>photos of dog breeds</SearchPhrase>
-                        <field>1091</field>
-                </row>
-                <row>
-                        <SearchPhrase>curtain designs</SearchPhrase>
-                        <field>1064</field>
-                </row>
-                <row>
-                        <SearchPhrase>baku</SearchPhrase>
-                        <field>1000</field>
-                </row>
-        </data>
-        <rows>10</rows>
-        <rows_before_limit_at_least>141137</rows_before_limit_at_least>
-</result>
-```
-
-Si el nombre de la columna no tiene un formato aceptable, simplemente ‘field’ se utiliza como el nombre del elemento. En general, la estructura XML sigue la estructura JSON.
-Just as for JSON, invalid UTF-8 sequences are changed to the replacement character � so the output text will consist of valid UTF-8 sequences.
-
-En los valores de cadena, los caracteres `<` y `&` se escaparon como `<` y `&`.
-
-Las matrices se emiten como `<array><elem>Hello</elem><elem>World</elem>...</array>`y tuplas como `<tuple><elem>Hello</elem><elem>World</elem>...</tuple>`.
-
-## CapnProto {#capnproto}
-
-Cap'n Proto es un formato de mensaje binario similar a Protocol Buffers y Thrift, pero no como JSON o MessagePack.
-
-Los mensajes de Cap'n Proto están estrictamente escritos y no autodescribidos, lo que significa que necesitan una descripción de esquema externo. El esquema se aplica sobre la marcha y se almacena en caché para cada consulta.
-
-``` bash
-$ cat capnproto_messages.bin | clickhouse-client --query "INSERT INTO test.hits FORMAT CapnProto SETTINGS format_schema='schema:Message'"
-```
-
-Donde `schema.capnp` se ve así:
-
-``` capnp
-struct Message {
-  SearchPhrase @0 :Text;
-  c @1 :Uint64;
-}
-```
-
-La deserialización es efectiva y generalmente no aumenta la carga del sistema.
-
-Ver también [Esquema de formato](#formatschema).
-
-## Protobuf {#protobuf}
-
-Protobuf - es un [Búferes de protocolo](https://developers.google.com/protocol-buffers/) formato.
-
-Este formato requiere un esquema de formato externo. El esquema se almacena en caché entre las consultas.
-ClickHouse soporta ambos `proto2` y `proto3` sintaxis. Se admiten campos repetidos / opcionales / requeridos.
-
-Ejemplos de uso:
-
-``` sql
-SELECT * FROM test.table FORMAT Protobuf SETTINGS format_schema = 'schemafile:MessageType'
-```
-
-``` bash
-cat protobuf_messages.bin | clickhouse-client --query "INSERT INTO test.table FORMAT Protobuf SETTINGS format_schema='schemafile:MessageType'"
-```
-
-donde el archivo `schemafile.proto` se ve así:
-
-``` capnp
-syntax = "proto3";
-
-message MessageType {
-  string name = 1;
-  string surname = 2;
-  uint32 birthDate = 3;
-  repeated string phoneNumbers = 4;
-};
-```
-
-Para encontrar la correspondencia entre las columnas de la tabla y los campos del tipo de mensaje de Protocol Buffers, ClickHouse compara sus nombres.
-Esta comparación no distingue entre mayúsculas y minúsculas y los caracteres `_` (subrayado) y `.` (punto) se consideran iguales.
-Si los tipos de una columna y un campo del mensaje de Protocol Buffers son diferentes, se aplica la conversión necesaria.
-
-Los mensajes anidados son compatibles. Por ejemplo, para el campo `z` en el siguiente tipo de mensaje
-
-``` capnp
-message MessageType {
-  message XType {
-    message YType {
-      int32 z;
-    };
-    repeated YType y;
-  };
-  XType x;
-};
-```
-
-ClickHouse intenta encontrar una columna llamada `x.y.z` (o `x_y_z` o `X.y_Z` y así sucesivamente).
-Los mensajes anidados son adecuados para [estructuras de datos anidados](../sql-reference/data-types/nested-data-structures/nested.md).
-
-Valores predeterminados definidos en un esquema protobuf como este
-
-``` capnp
-syntax = "proto2";
-
-message MessageType {
-  optional int32 result_per_page = 3 [default = 10];
-}
-```
-
-no se aplican; el [valores predeterminados de la tabla](../sql-reference/statements/create.md#create-default-values) se utilizan en lugar de ellos.
-
-ClickHouse entra y emite mensajes protobuf en el `length-delimited` formato.
-Significa que antes de cada mensaje debe escribirse su longitud como un [varint](https://developers.google.com/protocol-buffers/docs/encoding#varints).
-Ver también [cómo leer / escribir mensajes protobuf delimitados por longitud en idiomas populares](https://cwiki.apache.org/confluence/display/GEODE/Delimiting+Protobuf+Messages).
-
-## Avro {#data-format-avro}
-
-[Más información](http://avro.apache.org/) es un marco de serialización de datos orientado a filas desarrollado dentro del proyecto Hadoop de Apache.
-
-El formato ClickHouse Avro admite lectura y escritura [Archivos de datos Avro](http://avro.apache.org/docs/current/spec.html#Object+Container+Files).
-
-### Coincidencia de tipos de datos {#data_types-matching}
-

-
-\* [Tipos lógicos Avro](http://avro.apache.org/docs/current/spec.html#Logical+Types)
-
-Tipos de datos Avro no admitidos: `record` (no root), `map`
-
-Tipos de datos lógicos Avro no admitidos: `uuid`, `time-millis`, `time-micros`, `duration`
-
-### Insertar datos {#inserting-data-1}
-
-Para insertar datos de un archivo Avro en la tabla ClickHouse:
-
-``` bash
-$ cat file.avro | clickhouse-client --query="INSERT INTO {some_table} FORMAT Avro"
-```
-
-El esquema raíz del archivo Avro de entrada debe ser de `record` tipo.
-
-Para encontrar la correspondencia entre las columnas de la tabla y los campos de Avro esquema ClickHouse compara sus nombres. Esta comparación distingue entre mayúsculas y minúsculas.
-Los campos no utilizados se omiten.
-
-Los tipos de datos de las columnas de tabla ClickHouse pueden diferir de los campos correspondientes de los datos de Avro insertados. Al insertar datos, ClickHouse interpreta los tipos de datos de acuerdo con la tabla anterior y luego [elenco](../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) los datos al tipo de columna correspondiente.
-
-### Selección de datos {#selecting-data-1}
-
-Para seleccionar datos de la tabla ClickHouse en un archivo Avro:
-
-``` bash
-$ clickhouse-client --query="SELECT * FROM {some_table} FORMAT Avro" > file.avro
-```
-
-Los nombres de columna deben:
-
--   comenzar con `[A-Za-z_]`
--   posteriormente contienen sólo `[A-Za-z0-9_]`
-
-La compresión de archivos Avro de salida y el intervalo de sincronización se pueden configurar con [Sistema abierto.](../operations/settings/settings.md#settings-output_format_avro_codec) y [Sistema abierto.](../operations/settings/settings.md#settings-output_format_avro_sync_interval) respectivamente.
-
-## AvroConfluent {#data-format-avro-confluent}
-
-AvroConfluent admite la decodificación de mensajes Avro de un solo objeto comúnmente utilizados con [Kafka](https://kafka.apache.org/) y [Registro de Esquemas Confluentes](https://docs.confluent.io/current/schema-registry/index.html).
-
-Cada mensaje de Avro incrusta un id de esquema que se puede resolver en el esquema real con la ayuda del Registro de esquemas.
-
-Los esquemas se almacenan en caché una vez resueltos.
-
-La URL del registro de esquemas se configura con [Todos los derechos reservados.](../operations/settings/settings.md#settings-format_avro_schema_registry_url)
-
-### Coincidencia de tipos de datos {#data_types-matching-1}
-
-Lo mismo que [Avro](#data-format-avro)
-
-### Uso {#usage}
-
-Para verificar rápidamente la resolución del esquema, puede usar [Método de codificación de datos:](https://github.com/edenhill/kafkacat) con [Sistema abierto.](../operations/utilities/clickhouse-local.md#clickhouse-local):
-
-``` bash
-$ kafkacat -b kafka-broker  -C -t topic1 -o beginning -f '%s' -c 3 | clickhouse-local   --input-format AvroConfluent --format_avro_schema_registry_url 'http://schema-registry' -S "field1 Int64, field2 String"  -q 'select *  from table'
-1 a
-2 b
-3 c
-```
-
-Utilizar `AvroConfluent` con [Kafka](../engines/table-engines/integrations/kafka.md):
-
-``` sql
-CREATE TABLE topic1_stream
-(
-    field1 String,
-    field2 String
-)
-ENGINE = Kafka()
-SETTINGS
-kafka_broker_list = 'kafka-broker',
-kafka_topic_list = 'topic1',
-kafka_group_name = 'group1',
-kafka_format = 'AvroConfluent';
-
-SET format_avro_schema_registry_url = 'http://schema-registry';
-
-SELECT * FROM topic1_stream;
-```
-
-!!! note "Advertencia"
-    Configuración `format_avro_schema_registry_url` necesita ser configurado en `users.xml` para mantener su valor después de un reinicio.
-
-## Parquet {#data-format-parquet}
-
-[Apache Parquet](http://parquet.apache.org/) es un formato de almacenamiento columnar generalizado en el ecosistema Hadoop. ClickHouse admite operaciones de lectura y escritura para este formato.
-
-### Coincidencia de tipos de datos {#data_types-matching-2}
-

-
-ClickHouse admite una precisión configurable de `Decimal` tipo. El `INSERT` consulta trata el Parquet `DECIMAL` tipo como el ClickHouse `Decimal128` tipo.
-
-Tipos de datos de parquet no admitidos: `DATE32`, `TIME32`, `FIXED_SIZE_BINARY`, `JSON`, `UUID`, `ENUM`.
-
-Los tipos de datos de las columnas de tabla ClickHouse pueden diferir de los campos correspondientes de los datos de Parquet insertados. Al insertar datos, ClickHouse interpreta los tipos de datos de acuerdo con la tabla anterior y luego [elenco](../query_language/functions/type_conversion_functions/#type_conversion_function-cast) los datos de ese tipo de datos que se establece para la columna de tabla ClickHouse.
-
-### Insertar y seleccionar datos {#inserting-and-selecting-data}
-
-Puede insertar datos de Parquet desde un archivo en la tabla ClickHouse mediante el siguiente comando:
-
-``` bash
-$ cat {filename} | clickhouse-client --query="INSERT INTO {some_table} FORMAT Parquet"
-```
-
-Puede seleccionar datos de una tabla ClickHouse y guardarlos en algún archivo en el formato Parquet mediante el siguiente comando:
-
-``` bash
-$ clickhouse-client --query="SELECT * FROM {some_table} FORMAT Parquet" > {some_file.pq}
-```
-
-Para intercambiar datos con Hadoop, puede usar [Motor de mesa HDFS](../engines/table-engines/integrations/hdfs.md).
-
-## ORC {#data-format-orc}
-
-[Apache ORC](https://orc.apache.org/) es un formato de almacenamiento columnar generalizado en el ecosistema Hadoop. Solo puede insertar datos en este formato en ClickHouse.
-
-### Coincidencia de tipos de datos {#data_types-matching-3}
-
-La siguiente tabla muestra los tipos de datos admitidos y cómo coinciden con ClickHouse [tipos de datos](../sql-reference/data-types/index.md) en `INSERT` consulta.

-
-ClickHouse soporta la precisión configurable de la `Decimal` tipo. El `INSERT` consulta trata el ORC `DECIMAL` tipo como el ClickHouse `Decimal128` tipo.
-
-Tipos de datos ORC no admitidos: `DATE32`, `TIME32`, `FIXED_SIZE_BINARY`, `JSON`, `UUID`, `ENUM`.
-
-Los tipos de datos de las columnas de tabla ClickHouse no tienen que coincidir con los campos de datos ORC correspondientes. Al insertar datos, ClickHouse interpreta los tipos de datos de acuerdo con la tabla anterior y luego [elenco](../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) los datos al tipo de datos establecido para la columna de tabla ClickHouse.
-
-### Insertar datos {#inserting-data-2}
-
-Puede insertar datos ORC de un archivo en la tabla ClickHouse mediante el siguiente comando:
-
-``` bash
-$ cat filename.orc | clickhouse-client --query="INSERT INTO some_table FORMAT ORC"
-```
-
-Para intercambiar datos con Hadoop, puede usar [Motor de mesa HDFS](../engines/table-engines/integrations/hdfs.md).
-
-## Esquema de formato {#formatschema}
-
-El valor establece el nombre de archivo que contiene el esquema de formato `format_schema`.
-Es necesario establecer esta configuración cuando se utiliza uno de los formatos `Cap'n Proto` y `Protobuf`.
-El esquema de formato es una combinación de un nombre de archivo y el nombre de un tipo de mensaje en este archivo, delimitado por dos puntos,
-e.g. `schemafile.proto:MessageType`.
-Si el archivo tiene la extensión estándar para el formato (por ejemplo, `.proto` para `Protobuf`),
-se puede omitir y en este caso, el esquema de formato se ve así `schemafile:MessageType`.
-
-Si introduce o emite datos a través del [cliente](../interfaces/cli.md) en el [modo interactivo](../interfaces/cli.md#cli_usage), el nombre de archivo especificado en el esquema de formato
-puede contener una ruta absoluta o una ruta relativa al directorio actual en el cliente.
-Si utiliza el cliente en el [modo por lotes](../interfaces/cli.md#cli_usage), la ruta de acceso al esquema debe ser relativa por razones de seguridad.
-
-Si introduce o emite datos a través del [Interfaz HTTP](../interfaces/http.md) el nombre de archivo especificado en el esquema de formato
-debe estar ubicado en el directorio especificado en [format_schema_path](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-format_schema_path)
-en la configuración del servidor.
-
-## Salto de errores {#skippingerrors}
-
-Algunos formatos como `CSV`, `TabSeparated`, `TSKV`, `JSONEachRow`, `Template`, `CustomSeparated` y `Protobuf` puede omitir la fila rota si se produjo un error de análisis y continuar el análisis desde el comienzo de la siguiente fila. Ver [Entrada_format_allow_errors_num](../operations/settings/settings.md#settings-input_format_allow_errors_num) y
-[Entrada_format_allow_errors_ratio](../operations/settings/settings.md#settings-input_format_allow_errors_ratio) configuración.
-Limitacion:
-- En caso de error de análisis `JSONEachRow` omite todos los datos hasta la nueva línea (o EOF), por lo que las filas deben estar delimitadas por `\n` para contar los errores correctamente.
-- `Template` y `CustomSeparated` use el delimitador después de la última columna y el delimitador entre filas para encontrar el comienzo de la siguiente fila, por lo que omitir errores solo funciona si al menos uno de ellos no está vacío.

----
-
-# Interfaz HTTP {#http-interface}
-
-La interfaz HTTP le permite usar ClickHouse en cualquier plataforma desde cualquier lenguaje de programación. Lo usamos para trabajar desde Java y Perl, así como scripts de shell. En otros departamentos, la interfaz HTTP se usa desde Perl, Python y Go. La interfaz HTTP es más limitada que la interfaz nativa, pero tiene una mejor compatibilidad.
-
-De forma predeterminada, clickhouse-server escucha HTTP en el puerto 8123 (esto se puede cambiar en la configuración).
-
-Si realiza una solicitud GET / sin parámetros, devuelve 200 códigos de respuesta y la cadena que definió en [http_server_default_response](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-http_server_default_response) valor predeterminado “Ok.” (con un avance de línea al final)
-
-``` bash
-$ curl 'http://localhost:8123/'
-Ok.
-```
-
-Use la solicitud GET / ping en los scripts de comprobación de estado. Este controlador siempre devuelve “Ok.” (con un avance de línea al final). Disponible a partir de la versión 18.12.13.
-
-``` bash
-$ curl 'http://localhost:8123/ping'
-Ok.
-```
-
-Enviar la solicitud como una URL ‘query’ parámetro, o como un POST. O envíe el comienzo de la consulta en el ‘query’ parámetro, y el resto en el POST (explicaremos más adelante por qué esto es necesario). El tamaño de la URL está limitado a 16 KB, así que tenga esto en cuenta al enviar consultas grandes.
-
-Si tiene éxito, recibirá el código de respuesta 200 y el resultado en el cuerpo de respuesta.
-Si se produce un error, recibirá el código de respuesta 500 y un texto de descripción de error en el cuerpo de la respuesta.
-
-Al usar el método GET, ‘readonly’ se establece. En otras palabras, para consultas que modifican datos, solo puede usar el método POST. Puede enviar la consulta en sí misma en el cuerpo POST o en el parámetro URL.
-
-Ejemplos:
-
-``` bash
-$ curl 'http://localhost:8123/?query=SELECT%201'
-1
-
-$ wget -nv -O- 'http://localhost:8123/?query=SELECT 1'
-1
-
-$ echo -ne 'GET /?query=SELECT%201 HTTP/1.0\r\n\r\n' | nc localhost 8123
-HTTP/1.0 200 OK
-Date: Wed, 27 Nov 2019 10:30:18 GMT
-Connection: Close
-Content-Type: text/tab-separated-values; charset=UTF-8
-X-ClickHouse-Server-Display-Name: clickhouse.ru-central1.internal
-X-ClickHouse-Query-Id: 5abe861c-239c-467f-b955-8a201abb8b7f
-X-ClickHouse-Summary: {"read_rows":"0","read_bytes":"0","written_rows":"0","written_bytes":"0","total_rows_to_read":"0"}
-
-1
-```
-
-Como puede ver, curl es algo inconveniente ya que los espacios deben ser URL escapadas.
-Aunque wget escapa de todo en sí, no recomendamos usarlo porque no funciona bien sobre HTTP 1.1 cuando se usa keep-alive y Transfer-Encoding: chunked .
-
-``` bash
-$ echo 'SELECT 1' | curl 'http://localhost:8123/' --data-binary @-
-1
-
-$ echo 'SELECT 1' | curl 'http://localhost:8123/?query=' --data-binary @-
-1
-
-$ echo '1' | curl 'http://localhost:8123/?query=SELECT' --data-binary @-
-1
-```
-
-Si se envía parte de la consulta en el parámetro y parte en el POST, se inserta un avance de línea entre estas dos partes de datos.
-Ejemplo (esto no funcionará):
-
-``` bash
-$ echo 'ECT 1' | curl 'http://localhost:8123/?query=SEL' --data-binary @-
-Code: 59, e.displayText() = DB::Exception: Syntax error: failed at position 0: SEL
-ECT 1
-, expected One of: SHOW TABLES, SHOW DATABASES, SELECT, INSERT, CREATE, ATTACH, RENAME, DROP, DETACH, USE, SET, OPTIMIZE., e.what() = DB::Exception
-```
-
-De forma predeterminada, los datos se devuelven en formato TabSeparated (para obtener más información, “Formats” apartado).
-Utilice la cláusula FORMAT de la consulta para solicitar cualquier otro formato.
-
-``` bash
-$ echo 'SELECT 1 FORMAT Pretty' | curl 'http://localhost:8123/?' --data-binary @-
-┏━━━┓
-┃ 1 ┃
-┡━━━┩
-│ 1 │
-└───┘
-```
-
-El método POST de transmitir datos es necesario para las consultas INSERT. En este caso, puede escribir el comienzo de la consulta en el parámetro URL y usar POST para pasar los datos a insertar. Los datos a insertar podrían ser, por ejemplo, un volcado separado por tabuladores de MySQL. De esta manera, la consulta INSERT reemplaza LOAD DATA LOCAL INFILE de MySQL.
-
-Ejemplos: Crear una tabla:
-
-``` bash
-$ echo 'CREATE TABLE t (a UInt8) ENGINE = Memory' | curl 'http://localhost:8123/' --data-binary @-
-```
-
-Uso de la consulta INSERT familiar para la inserción de datos:
-
-``` bash
-$ echo 'INSERT INTO t VALUES (1),(2),(3)' | curl 'http://localhost:8123/' --data-binary @-
-```
-
-Los datos se pueden enviar por separado de la consulta:
-
-``` bash
-$ echo '(4),(5),(6)' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20VALUES' --data-binary @-
-```
-
-Puede especificar cualquier formato de datos. El ‘Values’ el formato es el mismo que el que se usa al escribir INSERT INTO t VALUES:
-
-``` bash
-$ echo '(7),(8),(9)' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20FORMAT%20Values' --data-binary @-
-```
-
-Para insertar datos de un volcado separado por tabuladores, especifique el formato correspondiente:
-
-``` bash
-$ echo -ne '10\n11\n12\n' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20FORMAT%20TabSeparated' --data-binary @-
-```
-
-Lectura del contenido de la tabla. Los datos se emiten en orden aleatorio debido al procesamiento de consultas paralelas:
-
-``` bash
-$ curl 'http://localhost:8123/?query=SELECT%20a%20FROM%20t'
-7
-8
-9
-10
-11
-12
-1
-2
-3
-4
-5
-6
-```
-
-Eliminando la mesa.
-
-``` bash
-$ echo 'DROP TABLE t' | curl 'http://localhost:8123/' --data-binary @-
-```
-
-Para las solicitudes correctas que no devuelven una tabla de datos, se devuelve un cuerpo de respuesta vacío.
-
-Puede utilizar el formato interno de compresión ClickHouse al transmitir datos. Los datos comprimidos tienen un formato no estándar, y deberá usar el `clickhouse-compressor` programa para trabajar con él (se instala con el `clickhouse-client` paquete). Para aumentar la eficiencia de la inserción de datos, puede deshabilitar la verificación de suma de comprobación [http_native_compression_disable_checksumming_on_decompress](../operations/settings/settings.md#settings-http_native_compression_disable_checksumming_on_decompress) configuración.
-
-Si ha especificado `compress=1` en la URL, el servidor comprime los datos que le envía.
-Si ha especificado `decompress=1` en la dirección URL, el servidor descomprime los mismos datos que `POST` método.
-
-También puede optar por utilizar [Compresión HTTP](https://en.wikipedia.org/wiki/HTTP_compression). Para enviar un `POST` solicitud, agregue el encabezado de solicitud `Content-Encoding: compression_method`. Para que ClickHouse comprima la respuesta, debe agregar `Accept-Encoding: compression_method`. Soporta ClickHouse `gzip`, `br`, y `deflate` [métodos de compresión](https://en.wikipedia.org/wiki/HTTP_compression#Content-Encoding_tokens). Para habilitar la compresión HTTP, debe usar ClickHouse [enable_http_compression](../operations/settings/settings.md#settings-enable_http_compression) configuración. Puede configurar el nivel de compresión de datos [http_zlib_compression_level](#settings-http_zlib_compression_level) para todos los métodos de compresión.
-
-Puede usar esto para reducir el tráfico de red al transmitir una gran cantidad de datos o para crear volcados que se comprimen inmediatamente.
-
-Ejemplos de envío de datos con compresión:
-
-``` bash
-#Sending data to the server:
-$ curl -vsS "http://localhost:8123/?enable_http_compression=1" -d 'SELECT number FROM system.numbers LIMIT 10' -H 'Accept-Encoding: gzip'
-
-#Sending data to the client:
-$ echo "SELECT 1" | gzip -c | curl -sS --data-binary @- -H 'Content-Encoding: gzip' 'http://localhost:8123/'
-```
-
-!!! note "Nota"
-    Algunos clientes HTTP pueden descomprimir datos del servidor de forma predeterminada (con `gzip` y `deflate`) y puede obtener datos descomprimidos incluso si usa la configuración de compresión correctamente.
-
-Puede usar el ‘database’ Parámetro URL para especificar la base de datos predeterminada.
-
-``` bash
-$ echo 'SELECT number FROM numbers LIMIT 10' | curl 'http://localhost:8123/?database=system' --data-binary @-
-0
-1
-2
-3
-4
-5
-6
-7
-8
-9
-```
-
-De forma predeterminada, la base de datos que está registrada en la configuración del servidor se utiliza como base de datos predeterminada. De forma predeterminada, esta es la base de datos llamada ‘default’. Como alternativa, siempre puede especificar la base de datos utilizando un punto antes del nombre de la tabla.
-
-El nombre de usuario y la contraseña se pueden indicar de una de estas tres maneras:
-
-1.  Uso de la autenticación básica HTTP. Ejemplo:
-
-<!-- -->
-
-``` bash
-$ echo 'SELECT 1' | curl 'http://user:password@localhost:8123/' -d @-
-```
-
-1.  En el ‘user’ y ‘password’ Parámetros de URL. Ejemplo:
-
-<!-- -->
-
-``` bash
-$ echo 'SELECT 1' | curl 'http://localhost:8123/?user=user&password=password' -d @-
-```
-
-1.  Utilizar ‘X-ClickHouse-User’ y ‘X-ClickHouse-Key’ cabecera. Ejemplo:
-
-<!-- -->
-
-``` bash
-$ echo 'SELECT 1' | curl -H 'X-ClickHouse-User: user' -H 'X-ClickHouse-Key: password' 'http://localhost:8123/' -d @-
-```
-
-Si no se especifica el nombre de usuario, `default` se utiliza el nombre. Si no se especifica la contraseña, se utiliza la contraseña vacía.
-También puede utilizar los parámetros de URL para especificar cualquier configuración para procesar una sola consulta o perfiles completos de configuración. Ejemplo:http://localhost:8123/?perfil=web&max_rows_to_read=1000000000&consulta=SELECCIONA+1
-
-Para obtener más información, consulte [Configuración](../operations/settings/index.md) apartado.
-
-``` bash
-$ echo 'SELECT number FROM system.numbers LIMIT 10' | curl 'http://localhost:8123/?' --data-binary @-
-0
-1
-2
-3
-4
-5
-6
-7
-8
-9
-```
-
-Para obtener información sobre otros parámetros, consulte la sección “SET”.
-
-Del mismo modo, puede utilizar sesiones ClickHouse en el protocolo HTTP. Para hacer esto, debe agregar el `session_id` GET parámetro a la solicitud. Puede usar cualquier cadena como ID de sesión. De forma predeterminada, la sesión finaliza después de 60 segundos de inactividad. Para cambiar este tiempo de espera, modifique `default_session_timeout` configuración en la configuración del servidor, o `session_timeout` GET parámetro a la solicitud. Para comprobar el estado de la sesión, `session_check=1` parámetro. Solo se puede ejecutar una consulta a la vez en una sola sesión.
-
-Puede recibir información sobre el progreso de una consulta en `X-ClickHouse-Progress` encabezados de respuesta. Para hacer esto, habilite [send_progress_in_http_headers](../operations/settings/settings.md#settings-send_progress_in_http_headers). Ejemplo de la secuencia de encabezado:
-
-``` text
-X-ClickHouse-Progress: {"read_rows":"2752512","read_bytes":"240570816","total_rows_to_read":"8880128"}
-X-ClickHouse-Progress: {"read_rows":"5439488","read_bytes":"482285394","total_rows_to_read":"8880128"}
-X-ClickHouse-Progress: {"read_rows":"8783786","read_bytes":"819092887","total_rows_to_read":"8880128"}
-```
-
-Posibles campos de encabezado:
-
--   `read_rows` — Number of rows read.
--   `read_bytes` — Volume of data read in bytes.
--   `total_rows_to_read` — Total number of rows to be read.
--   `written_rows` — Number of rows written.
--   `written_bytes` — Volume of data written in bytes.
-
-Las solicitudes en ejecución no se detienen automáticamente si se pierde la conexión HTTP. El análisis y el formato de datos se realizan en el lado del servidor, y el uso de la red puede ser ineficaz.
-Opcional ‘query_id’ parámetro se puede pasar como el ID de consulta (cualquier cadena). Para obtener más información, consulte la sección “Settings, replace_running_query”.
-
-Opcional ‘quota_key’ parámetro se puede pasar como la clave de cuota (cualquier cadena). Para obtener más información, consulte la sección “Quotas”.
-
-La interfaz HTTP permite pasar datos externos (tablas temporales externas) para consultar. Para obtener más información, consulte la sección “External data for query processing”.
-
-## Almacenamiento en búfer de respuesta {#response-buffering}
-
-Puede habilitar el almacenamiento en búfer de respuestas en el lado del servidor. El `buffer_size` y `wait_end_of_query` Los parámetros URL se proporcionan para este propósito.
-
-`buffer_size` determina el número de bytes en el resultado para almacenar en búfer en la memoria del servidor. Si un cuerpo de resultado es mayor que este umbral, el búfer se escribe en el canal HTTP y los datos restantes se envían directamente al canal HTTP.
-
-Para asegurarse de que toda la respuesta se almacena en búfer, establezca `wait_end_of_query=1`. En este caso, los datos que no se almacenan en la memoria se almacenarán en un archivo de servidor temporal.
-
-Ejemplo:
-
-``` bash
-$ curl -sS 'http://localhost:8123/?max_result_bytes=4000000&buffer_size=3000000&wait_end_of_query=1' -d 'SELECT toUInt8(number) FROM system.numbers LIMIT 9000000 FORMAT RowBinary'
-```
-
-Utilice el almacenamiento en búfer para evitar situaciones en las que se produjo un error de procesamiento de consultas después de enviar al cliente el código de respuesta y los encabezados HTTP. En esta situación, se escribe un mensaje de error al final del cuerpo de la respuesta y, en el lado del cliente, el error solo se puede detectar en la etapa de análisis.
-
-### Consultas con parámetros {#cli-queries-with-parameters}
-
-Puede crear una consulta con parámetros y pasar valores para ellos desde los parámetros de solicitud HTTP correspondientes. Para obtener más información, consulte [Consultas con parámetros para CLI](cli.md#cli-queries-with-parameters).
-
-### Ejemplo {#example}
-
-``` bash
-$ curl -sS "<address>?param_id=2&param_phrase=test" -d "SELECT * FROM table WHERE int_column = {id:UInt8} and string_column = {phrase:String}"
-```
-
-## Interfaz HTTP predefinida {#predefined_http_interface}
-
-ClickHouse admite consultas específicas a través de la interfaz HTTP. Por ejemplo, puede escribir datos en una tabla de la siguiente manera:
-
-``` bash
-$ echo '(4),(5),(6)' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20VALUES' --data-binary @-
-```
-
-ClickHouse también es compatible con la interfaz HTTP predefinida que puede ayudarle a una integración más fácil con herramientas de terceros como [Prometheus exportador](https://github.com/percona-lab/clickhouse_exporter).
-
-Ejemplo:
-
--   En primer lugar, agregue esta sección al archivo de configuración del servidor:
-
-<!-- -->
-
-``` xml
-<http_handlers>
-    <rule>
-        <url>/predefined_query</url>
-        <methods>POST,GET</methods>
-        <handler>
-            <type>predefined_query_handler</type>
-            <query>SELECT * FROM system.metrics LIMIT 5 FORMAT Template SETTINGS format_template_resultset = 'prometheus_template_output_format_resultset', format_template_row = 'prometheus_template_output_format_row', format_template_rows_between_delimiter = '\n'</query>
-        </handler>
-    </rule>
-    <rule>...</rule>
-    <rule>...</rule>
-</http_handlers>
-```
-
--   Ahora puede solicitar la url directamente para los datos en el formato Prometheus:
-
-<!-- -->
-
-``` bash
-$ curl -v 'http://localhost:8123/predefined_query'
-*   Trying ::1...
-* Connected to localhost (::1) port 8123 (#0)

-
-Como puede ver en el ejemplo, si `<http_handlers>` está configurado en la configuración.archivo xml y `<http_handlers>` puede contener muchos `<rule>s`. ClickHouse coincidirá con las solicitudes HTTP recibidas con el tipo predefinido en `<rule>` y el primer emparejado ejecuta el controlador. Luego, ClickHouse ejecutará la consulta predefinida correspondiente si la coincidencia es exitosa.
-
-> Ahora `<rule>` puede configurar `<method>`, `<headers>`, `<url>`,`<handler>`:
-> `<method>` es responsable de hacer coincidir la parte del método de la solicitud HTTP. `<method>` se ajusta plenamente a la definición de [método](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods) en el protocolo HTTP. Es una configuración opcional. Si no está definido en el archivo de configuración, no coincide con la parte del método de la solicitud HTTP.
->
-> `<url>` es responsable de hacer coincidir la parte url de la solicitud HTTP. Es compatible con [RE2](https://github.com/google/re2)expresiones regulares. Es una configuración opcional. Si no está definido en el archivo de configuración, no coincide con la parte url de la solicitud HTTP.
->
-> `<headers>` es responsable de hacer coincidir la parte del encabezado de la solicitud HTTP. Es compatible con las expresiones regulares de RE2. Es una configuración opcional. Si no está definido en el archivo de configuración, no coincide con la parte de encabezado de la solicitud HTTP.
->
-> `<handler>` contiene la parte de procesamiento principal. Ahora `<handler>` puede configurar `<type>`, `<status>`, `<content_type>`, `<response_content>`, `<query>`, `<query_param_name>`.
-> \> `<type>` Actualmente soporta tres tipos: **Dirección de correo electrónico**, **Nombre de la red inalámbrica (SSID):**, **estática**.
-> \>
-> \> `<query>` - utilizar con el tipo predefined_query_handler, ejecuta la consulta cuando se llama al controlador.
-> \>
-> \> `<query_param_name>` - utilizar con el tipo dynamic_query_handler, extrae y ejecuta el valor correspondiente al `<query_param_name>` valor en parámetros de solicitud HTTP.
-> \>
-> \> `<status>` - uso con tipo estático, código de estado de respuesta.
-> \>
-> \> `<content_type>` - uso con tipo estático, respuesta [tipo de contenido](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Type).
-> \>
-> \> `<response_content>` - uso con tipo estático, contenido de respuesta enviado al cliente, cuando se usa el prefijo ‘file://’ o ‘config://’, encontrar el contenido del archivo o configuración enviar al cliente.
-
-A continuación están los métodos de configuración para los diferentes `<type>`.
-
-## Dirección de correo electrónico {#predefined_query_handler}
-
-`<predefined_query_handler>` admite la configuración de valores Settings y query_params. Puede configurar `<query>` en el tipo de `<predefined_query_handler>`.
-
-`<query>` valor es una consulta predefinida de `<predefined_query_handler>`, que es ejecutado por ClickHouse cuando se hace coincidir una solicitud HTTP y se devuelve el resultado de la consulta. Es una configuración imprescindible.
-
-En el ejemplo siguiente se definen los valores de `max_threads` y `max_alter_threads` configuración, a continuación, consulta la tabla del sistema para comprobar si estos ajustes se han establecido correctamente.
-
-Ejemplo:
-
-``` xml
-<http_handlers>
-    <rule>
-        <url><![CDATA[/query_param_with_url/\w+/(?P<name_1>[^/]+)(/(?P<name_2>[^/]+))?]]></url>
-        <method>GET</method>
-        <headers>
-            <XXX>TEST_HEADER_VALUE</XXX>
-            <PARAMS_XXX><![CDATA[(?P<name_1>[^/]+)(/(?P<name_2>[^/]+))?]]></PARAMS_XXX>
-        </headers>
-        <handler>
-            <type>predefined_query_handler</type>
-            <query>SELECT value FROM system.settings WHERE name = {name_1:String}</query>
-            <query>SELECT name, value FROM system.settings WHERE name = {name_2:String}</query>
-        </handler>
-    </rule>
-</http_handlers>
-```
-
-``` bash
-$ curl -H 'XXX:TEST_HEADER_VALUE' -H 'PARAMS_XXX:max_threads' 'http://localhost:8123/query_param_with_url/1/max_threads/max_alter_threads?max_threads=1&max_alter_threads=2'
-1
-max_alter_threads   2
-```
-
-!!! note "precaución"
-    En uno `<predefined_query_handler>` sólo es compatible con uno `<query>` de un tipo de plaquita.
-
-## Nombre de la red inalámbrica (SSID): {#dynamic_query_handler}
-
-En `<dynamic_query_handler>`, consulta se escribe en forma de param de la solicitud HTTP. La diferencia es que en `<predefined_query_handler>`, consulta se escribe en el archivo de configuración. Puede configurar `<query_param_name>` en `<dynamic_query_handler>`.
-
-ClickHouse extrae y ejecuta el valor correspondiente al `<query_param_name>` valor en la url de la solicitud HTTP. El valor predeterminado de `<query_param_name>` ser `/query` . Es una configuración opcional. Si no hay una definición en el archivo de configuración, el parámetro no se pasa.
-
-Para experimentar con esta funcionalidad, el ejemplo define los valores de max_threads y max_alter_threads y consulta si la configuración se estableció correctamente.
-
-Ejemplo:
-
-``` xml
-<http_handlers>
-    <rule>
-    <headers>
-        <XXX>TEST_HEADER_VALUE_DYNAMIC</XXX>    </headers>
-    <handler>
-        <type>dynamic_query_handler</type>
-        <query_param_name>query_param</query_param_name>
-    </handler>
-    </rule>
-</http_handlers>
-```
-
-``` bash
-$ curl  -H 'XXX:TEST_HEADER_VALUE_DYNAMIC'  'http://localhost:8123/own?max_threads=1&max_alter_threads=2&param_name_1=max_threads&param_name_2=max_alter_threads&query_param=SELECT%20name,value%20FROM%20system.settings%20where%20name%20=%20%7Bname_1:String%7D%20OR%20name%20=%20%7Bname_2:String%7D'
-max_threads 1
-max_alter_threads   2
-```
-
-## estática {#static}
-
-`<static>` puede volver [Content_type](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Type), [estatus](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status) y response_content. response_content puede devolver el contenido especificado
-
-Ejemplo:
-
-Devuelve un mensaje.

-# Interfaz {#interfaces}
-
-ClickHouse proporciona dos interfaces de red (ambas se pueden ajustar opcionalmente en TLS para mayor seguridad):
-
--   [HTTP](http.md), que está documentado y fácil de usar directamente.
--   [TCP nativo](tcp.md), que tiene menos sobrecarga.
-
-En la mayoría de los casos, se recomienda utilizar la herramienta o biblioteca apropiada en lugar de interactuar con ellos directamente. Oficialmente apoyados por Yandex son los siguientes:
-
--   [Cliente de línea de comandos](cli.md)
--   [Controlador JDBC](jdbc.md)
--   [Controlador ODBC](odbc.md)
--   [Biblioteca cliente de C++](cpp.md)
-
-También hay una amplia gama de bibliotecas de terceros para trabajar con ClickHouse:
-
--   [Bibliotecas de clientes](third-party/client-libraries.md)
--   [Integración](third-party/integrations.md)
--   [Interfaces visuales](third-party/gui.md)

-# Interfaz MySQL {#mysql-interface}
-
-ClickHouse soporta el protocolo de cable MySQL. Puede ser habilitado por [mysql_port](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-mysql_port) configuración en el archivo de configuración:
-
-``` xml
-<mysql_port>9004</mysql_port>
-```
-
-Ejemplo de conexión mediante la herramienta de línea de comandos `mysql`:
-
-``` bash
-$ mysql --protocol tcp -u default -P 9004
-```
-
-Salida si una conexión se realizó correctamente:
-
-``` text
-Welcome to the MySQL monitor.  Commands end with ; or \g.
-Your MySQL connection id is 4
-Server version: 20.2.1.1-ClickHouse
-
-Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.
-
-Oracle is a registered trademark of Oracle Corporation and/or its
-affiliates. Other names may be trademarks of their respective
-owners.
-
-Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
-
-mysql>
-```
-
-Para la compatibilidad con todos los clientes MySQL, se recomienda especificar la contraseña de usuario con [doble SHA1](../operations/settings/settings-users.md#password_double_sha1_hex) en el archivo de configuración.
-Si la contraseña de usuario se especifica usando [SHA256](../operations/settings/settings-users.md#password_sha256_hex), algunos clientes no podrán autenticarse (mysqljs y versiones antiguas de la herramienta de línea de comandos mysql).
-
-Restricción:
-
--   las consultas preparadas no son compatibles
-
--   algunos tipos de datos se envían como cadenas

-# Interfaz nativa (TCP) {#native-interface-tcp}
-
-El protocolo nativo se utiliza en el [cliente de línea de comandos](cli.md), para la comunicación entre servidores durante el procesamiento de consultas distribuidas, y también en otros programas de C, Desafortunadamente, el protocolo nativo de ClickHouse aún no tiene especificaciones formales, pero puede ser diseñado de manera inversa desde el código fuente de ClickHouse (comenzando [por aquí](https://github.com/ClickHouse/ClickHouse/tree/master/src/Client)) y/o mediante la interceptación y el análisis del tráfico TCP.

----
-
-# Características distintivas de ClickHouse {#distinctive-features-of-clickhouse}
-
-## DBMS orientado a columnas verdaderas {#true-column-oriented-dbms}
-
-En un verdadero DBMS orientado a columnas, no se almacenan datos adicionales con los valores. Entre otras cosas, esto significa que los valores de longitud constante deben ser compatibles, para evitar almacenar su longitud “number” al lado de los valores. Como ejemplo, mil millones de valores de tipo UInt8 deberían consumir alrededor de 1 GB sin comprimir, o esto afecta fuertemente el uso de la CPU. Es esencial almacenar los datos de forma compacta (sin “garbage”) incluso sin comprimir, ya que la velocidad de descompresión (uso de CPU) depende principalmente del volumen de datos sin comprimir.
-
-Vale la pena señalar porque hay sistemas que pueden almacenar valores de diferentes columnas por separado, pero que no pueden procesar efectivamente las consultas analíticas debido a su optimización para otros escenarios. Los ejemplos son HBase, BigTable, Cassandra e HyperTable. En estos sistemas, obtendría un rendimiento de alrededor de cien mil filas por segundo, pero no cientos de millones de filas por segundo.
-
-También vale la pena señalar que ClickHouse es un sistema de administración de bases de datos, no una sola base de datos. ClickHouse permite crear tablas y bases de datos en tiempo de ejecución, cargar datos y ejecutar consultas sin volver a configurar y reiniciar el servidor.
-
-## Compresión de datos {#data-compression}
-
-Algunos DBMS orientados a columnas (InfiniDB CE y MonetDB) no utilizan la compresión de datos. Sin embargo, la compresión de datos juega un papel clave para lograr un rendimiento excelente.
-
-## Almacenamiento en disco de datos {#disk-storage-of-data}
-
-Mantener los datos físicamente ordenados por clave principal permite extraer datos para sus valores específicos o rangos de valores con baja latencia, menos de unas pocas docenas de milisegundos. Algunos DBMS orientados a columnas (como SAP HANA y Google PowerDrill) solo pueden funcionar en RAM. Este enfoque fomenta la asignación de un presupuesto de hardware más grande que el necesario para el análisis en tiempo real. ClickHouse está diseñado para funcionar en discos duros normales, lo que significa que el costo por GB de almacenamiento de datos es bajo, pero SSD y RAM adicional también se utilizan completamente si están disponibles.
-
-## Procesamiento paralelo en varios núcleos {#parallel-processing-on-multiple-cores}
-
-Las consultas grandes se paralelizan naturalmente, tomando todos los recursos necesarios disponibles en el servidor actual.
-
-## Procesamiento distribuido en varios servidores {#distributed-processing-on-multiple-servers}
-
-Casi ninguno de los DBMS columnar mencionados anteriormente tiene soporte para el procesamiento de consultas distribuidas.
-En ClickHouse, los datos pueden residir en diferentes fragmentos. Cada fragmento puede ser un grupo de réplicas utilizadas para la tolerancia a errores. Todos los fragmentos se utilizan para ejecutar una consulta en paralelo, de forma transparente para el usuario.
-
-## Soporte SQL {#sql-support}
-
-ClickHouse admite un lenguaje de consulta declarativo basado en SQL que es idéntico al estándar SQL en muchos casos.
-Las consultas admitidas incluyen GROUP BY, ORDER BY, subconsultas en cláusulas FROM, IN y JOIN y subconsultas escalares.
-No se admiten subconsultas y funciones de ventana dependientes.
-
-## Motor del vector {#vector-engine}
-
-Los datos no solo se almacenan mediante columnas, sino que se procesan mediante vectores (partes de columnas), lo que permite lograr una alta eficiencia de CPU.
-
-## Actualizaciones de datos en tiempo real {#real-time-data-updates}
-
-ClickHouse admite tablas con una clave principal. Para realizar consultas rápidamente en el rango de la clave principal, los datos se ordenan de forma incremental utilizando el árbol de combinación. Debido a esto, los datos se pueden agregar continuamente a la tabla. No se toman bloqueos cuando se ingieren nuevos datos.
-
-## Indice {#index}
-
-Tener un dato ordenado físicamente por clave principal permite extraer datos para sus valores específicos o rangos de valores con baja latencia, menos de unas pocas docenas de milisegundos.
-
-## Adecuado para consultas en línea {#suitable-for-online-queries}
-
-La baja latencia significa que las consultas se pueden procesar sin demora y sin intentar preparar una respuesta por adelantado, justo en el mismo momento mientras se carga la página de la interfaz de usuario. En otras palabras, en línea.
-
-## Soporte para cálculos aproximados {#support-for-approximated-calculations}
-
-ClickHouse proporciona varias formas de intercambiar precisión por rendimiento:
-
-1.  Funciones agregadas para el cálculo aproximado del número de valores distintos, medianas y cuantiles.
-2.  Ejecutar una consulta basada en una parte (muestra) de datos y obtener un resultado aproximado. En este caso, se recuperan proporcionalmente menos datos del disco.
-3.  Ejecutar una agregación para un número limitado de claves aleatorias, en lugar de para todas las claves. Bajo ciertas condiciones para la distribución de claves en los datos, esto proporciona un resultado razonablemente preciso mientras se utilizan menos recursos.
-
-## Replicación de datos e integridad de datos {#data-replication-and-data-integrity-support}
-
-ClickHouse utiliza la replicación multi-maestro asincrónica. Después de escribir en cualquier réplica disponible, todas las réplicas restantes recuperan su copia en segundo plano. El sistema mantiene datos idénticos en diferentes réplicas. La recuperación después de la mayoría de las fallas se realiza automáticamente, o semiautomáticamente en casos complejos.
-
-Para obtener más información, consulte la sección [Replicación de datos](../engines/table-engines/mergetree-family/replication.md).
-
-## Características que pueden considerarse desventajas {#clickhouse-features-that-can-be-considered-disadvantages}
-
-1.  No hay transacciones completas.
-2.  Falta de capacidad para modificar o eliminar datos ya insertados con alta tasa y baja latencia. Hay eliminaciones y actualizaciones por lotes disponibles para limpiar o modificar datos, por ejemplo, para cumplir con [GDPR](https://gdpr-info.eu).
-3.  El índice disperso hace que ClickHouse no sea tan adecuado para consultas de puntos que recuperan filas individuales por sus claves.

-# Historial de ClickHouse {#clickhouse-history}
-
-ClickHouse se ha desarrollado inicialmente para alimentar [El Yandex.Métrica](https://metrica.yandex.com/), [la segunda plataforma de análisis web más grande del mundo](http://w3techs.com/technologies/overview/traffic_analysis/all), y sigue siendo el componente central de este sistema. Con más de 13 billones de registros en la base de datos y más de 20 mil millones de eventos diarios, ClickHouse permite generar informes personalizados sobre la marcha directamente a partir de datos no agregados. Este artículo cubre brevemente los objetivos de ClickHouse en las primeras etapas de su desarrollo.
-
-El Yandex.Metrica construye informes personalizados sobre la marcha basados en hits y sesiones, con segmentos arbitrarios definidos por el usuario. Hacerlo a menudo requiere construir agregados complejos, como el número de usuarios únicos. Los nuevos datos para crear un informe llegan en tiempo real.
-
-A partir de abril de 2014, Yandex.Metrica estaba rastreando alrededor de 12 mil millones de eventos (vistas de páginas y clics) diariamente. Todos estos eventos deben almacenarse para crear informes personalizados. Una sola consulta puede requerir escanear millones de filas en unos pocos cientos de milisegundos, o cientos de millones de filas en solo unos segundos.
-
-## Uso en Yandex.Metrica y otros servicios de Yandex {#usage-in-yandex-metrica-and-other-yandex-services}
-
-ClickHouse sirve para múltiples propósitos en Yandex.Métrica.
-Su tarea principal es crear informes en modo en línea utilizando datos no agregados. Utiliza un clúster de 374 servidores, que almacenan más de 20,3 billones de filas en la base de datos. El volumen de datos comprimidos es de aproximadamente 2 PB, sin tener en cuenta duplicados y réplicas. El volumen de datos sin comprimir (en formato TSV) sería de aproximadamente 17 PB.
-
-ClickHouse también juega un papel clave en los siguientes procesos:
-
--   Almacenamiento de datos para Session Replay de Yandex.Métrica.
--   Procesamiento de datos intermedios.
--   Creación de informes globales con Analytics.
--   Ejecutar consultas para depurar el Yandex.Motor Metrica.
--   Análisis de registros desde la API y la interfaz de usuario.
-
-Hoy en día, hay varias docenas de instalaciones de ClickHouse en otros servicios y departamentos de Yandex: verticales de búsqueda, comercio electrónico, publicidad, análisis de negocios, desarrollo móvil, servicios personales y otros.
-
-## Datos agregados y no agregados {#aggregated-and-non-aggregated-data}
-
-Existe una opinión generalizada de que para calcular las estadísticas de manera efectiva, debe agregar datos ya que esto reduce el volumen de datos.
-
-Pero la agregación de datos viene con muchas limitaciones:
-
--   Debe tener una lista predefinida de los informes necesarios.
--   El usuario no puede hacer informes personalizados.
--   Al agregar sobre un gran número de claves distintas, el volumen de datos apenas se reduce, por lo que la agregación es inútil.
--   Para un gran número de informes, hay demasiadas variaciones de agregación (explosión combinatoria).
--   Al agregar claves con alta cardinalidad (como las URL), el volumen de datos no se reduce en mucho (menos del doble).
--   Por esta razón, el volumen de datos con agregación podría crecer en lugar de reducirse.
--   Los usuarios no ven todos los informes que generamos para ellos. Una gran parte de esos cálculos es inútil.
--   La integridad lógica de los datos puede ser violada para varias agregaciones.
-
-Si no agregamos nada y trabajamos con datos no agregados, esto podría reducir el volumen de cálculos.
-
-Sin embargo, con la agregación, una parte significativa del trabajo se desconecta y se completa con relativa calma. Por el contrario, los cálculos en línea requieren calcular lo más rápido posible, ya que el usuario está esperando el resultado.
-
-El Yandex.Metrica tiene un sistema especializado para agregar datos llamado Metrage, que se utilizó para la mayoría de los informes.
-A partir de 2009, Yandex.Metrica también utilizó una base de datos OLAP especializada para datos no agregados llamada OLAPServer, que anteriormente se usaba para el generador de informes.
-OLAPServer funcionó bien para datos no agregados, pero tenía muchas restricciones que no permitían que se utilizara para todos los informes según lo deseado. Estos incluyeron la falta de soporte para tipos de datos (solo números) y la incapacidad de actualizar datos de forma incremental en tiempo real (solo se podía hacer reescribiendo datos diariamente). OLAPServer no es un DBMS, sino una base de datos especializada.
-
-El objetivo inicial de ClickHouse era eliminar las limitaciones de OLAPServer y resolver el problema de trabajar con datos no agregados para todos los informes, pero a lo largo de los años, se ha convertido en un sistema de gestión de bases de datos de propósito general adecuado para una amplia gama de tareas analíticas.

----
-
-# Rendimiento {#performance}
-
-De acuerdo con los resultados de las pruebas internas en Yandex, ClickHouse muestra el mejor rendimiento (tanto el mayor rendimiento para consultas largas como la menor latencia en consultas cortas) para escenarios operativos comparables entre los sistemas de su clase que estaban disponibles para pruebas. Puede ver los resultados de la prueba en un [página separada](https://clickhouse.tech/benchmark/dbms/).
-
-Numerosos puntos de referencia independientes llegaron a conclusiones similares. No son difíciles de encontrar mediante una búsqueda en Internet, o se puede ver [nuestra pequeña colección de enlaces relacionados](https://clickhouse.tech/#independent-benchmarks).
-
-## Rendimiento para una única consulta grande {#throughput-for-a-single-large-query}
-
-El rendimiento se puede medir en filas por segundo o megabytes por segundo. Si los datos se colocan en la caché de la página, una consulta que no es demasiado compleja se procesa en hardware moderno a una velocidad de aproximadamente 2-10 GB / s de datos sin comprimir en un solo servidor (para los casos más sencillos, la velocidad puede alcanzar 30 GB / s). Si los datos no se colocan en la memoria caché de la página, la velocidad depende del subsistema de disco y la velocidad de compresión de datos. Por ejemplo, si el subsistema de disco permite leer datos a 400 MB/s y la tasa de compresión de datos es 3, se espera que la velocidad sea de alrededor de 1,2 GB/s. Para obtener la velocidad en filas por segundo, divida la velocidad en bytes por segundo por el tamaño total de las columnas utilizadas en la consulta. Por ejemplo, si se extraen 10 bytes de columnas, se espera que la velocidad sea de alrededor de 100-200 millones de filas por segundo.
-
-La velocidad de procesamiento aumenta casi linealmente para el procesamiento distribuido, pero solo si el número de filas resultantes de la agregación o la clasificación no es demasiado grande.
-
-## Latencia al procesar consultas cortas {#latency-when-processing-short-queries}
-
-Si una consulta usa una clave principal y no selecciona demasiadas columnas y filas para procesar (cientos de miles), puede esperar menos de 50 milisegundos de latencia (dígitos individuales de milisegundos en el mejor de los casos) si los datos se colocan en la memoria caché de la página. De lo contrario, la latencia está dominada principalmente por el número de búsquedas. Si utiliza unidades de disco giratorias, para un sistema que no está sobrecargado, la latencia se puede estimar con esta fórmula: `seek time (10 ms) * count of columns queried * count of data parts`.
-
-## Rendimiento al procesar una gran cantidad de consultas cortas {#throughput-when-processing-a-large-quantity-of-short-queries}
-
-En las mismas condiciones, ClickHouse puede manejar varios cientos de consultas por segundo en un solo servidor (hasta varios miles en el mejor de los casos). Dado que este escenario no es típico para DBMS analíticos, se recomienda esperar un máximo de 100 consultas por segundo.
-
-## Rendimiento al insertar datos {#performance-when-inserting-data}
-
-Recomendamos insertar datos en paquetes de al menos 1000 filas o no más de una sola solicitud por segundo. Al insertar en una tabla MergeTree desde un volcado separado por tabuladores, la velocidad de inserción puede ser de 50 a 200 MB/s. Si las filas insertadas tienen alrededor de 1 Kb de tamaño, la velocidad será de 50,000 a 200,000 filas por segundo. Si las filas son pequeñas, el rendimiento puede ser mayor en filas por segundo (en los datos del sistema Banner -`>` 500.000 filas por segundo; en datos de grafito -`>` 1.000.000 de filas por segundo). Para mejorar el rendimiento, puede realizar varias consultas INSERT en paralelo, que se escala linealmente.

-
-# Control de acceso y gestión de cuentas {#access-control}
-
-ClickHouse admite la administración de control de acceso basada en [RBAC](https://en.wikipedia.org/wiki/Role-based_access_control) enfoque.
-
-Entidades de acceso de ClickHouse:
-- [Cuenta de usuario](#user-account-management)
-- [Rol](#role-management)
-- [Política de fila](#row-policy-management)
-- [Perfil de configuración](#settings-profiles-management)
-- [Cuota](#quotas-management)
-
-Puede configurar entidades de acceso utilizando:
-
--   Flujo de trabajo controlado por SQL.
-
-    Es necesario [permitir](#enabling-access-control) esta funcionalidad.
-
--   Servidor [archivos de configuración](configuration-files.md) `users.xml` y `config.xml`.
-
-Se recomienda utilizar el flujo de trabajo controlado por SQL. Ambos métodos de configuración funcionan simultáneamente, por lo que si utiliza los archivos de configuración del servidor para administrar cuentas y derechos de acceso, puede pasar suavemente al flujo de trabajo controlado por SQL.
-
-!!! note "Advertencia"
-    No puede administrar la misma entidad de acceso mediante ambos métodos de configuración simultáneamente.
-
-## Uso {#access-control-usage}
-
-De forma predeterminada, el servidor ClickHouse proporciona la cuenta de usuario `default` que no está permitido usar control de acceso controlado por SQL y administración de cuentas, pero tiene todos los derechos y permisos. El `default` cuenta de usuario se utiliza en cualquier caso cuando el nombre de usuario no está definido, por ejemplo, al iniciar sesión desde el cliente o en consultas distribuidas. En el procesamiento de consultas distribuidas se utiliza una cuenta de usuario predeterminada, si la configuración del servidor o clúster no [usuario y contraseña](../engines/table-engines/special/distributed.md) propiedad.
-
-Si acaba de comenzar a usar ClickHouse, puede usar el siguiente escenario:
-
-1.  [Permitir](#enabling-access-control) Control de acceso basado en SQL y gestión de cuentas `default` usuario.
-2.  Inicie sesión bajo el `default` cuenta de usuario y crear todos los usuarios. No olvides crear una cuenta de administrador (`GRANT ALL ON *.* WITH GRANT OPTION TO admin_user_account`).
-3.  [Restringir permisos](settings/permissions-for-queries.md#permissions_for_queries) para el `default` usuario y deshabilitar el control de acceso impulsado por SQL y la administración de cuentas para ello.
-
-### Propiedades de la solución actual {#access-control-properties}
-
--   Puede conceder permisos para bases de datos y tablas incluso si no existen.
--   Si se eliminó una tabla, no se revocarán todos los privilegios que corresponden a esta tabla. Por lo tanto, si se crea una nueva tabla más tarde con el mismo nombre, todos los privilegios vuelven a ser reales. Para revocar los privilegios correspondientes a la tabla eliminada, debe realizar, por ejemplo, el `REVOKE ALL PRIVILEGES ON db.table FROM ALL` consulta.
--   No hay ninguna configuración de por vida para los privilegios.
-
-## Cuenta de usuario {#user-account-management}
-
-Una cuenta de usuario es una entidad de acceso que permite autorizar a alguien en ClickHouse. Una cuenta de usuario contiene:
-

-toc_title: Copia de seguridad de datos
----
-
-# Copia de seguridad de datos {#data-backup}
-
-Mientras que la [replicación](../engines/table-engines/mergetree-family/replication.md) proporciona protección contra fallos de hardware, no protege de errores humanos: el borrado accidental de datos, elminar la tabla equivocada o una tabla en el clúster equivocado, y bugs de software que dan como resultado un procesado incorrecto de los datos o la corrupción de los datos. En muchos casos, errores como estos afectarán a todas las réplicas. ClickHouse dispone de salvaguardas para prevenir algunos tipos de errores — por ejemplo, por defecto [no se puede simplemente eliminar tablas con un motor similar a MergeTree que contenga más de 50 Gb de datos](server-configuration-parameters/settings.md#max-table-size-to-drop). Sin embargo, estas salvaguardas no cubren todos los casos posibles y pueden eludirse.
-
-Para mitigar eficazmente los posibles errores humanos, debe preparar cuidadosamente una estrategia para realizar copias de seguridad y restaurar sus datos **previamente**.
-
-Cada empresa tiene diferentes recursos disponibles y requisitos comerciales, por lo que no existe una solución universal para las copias de seguridad y restauraciones de ClickHouse que se adapten a cada situación. Lo que funciona para un gigabyte de datos probablemente no funcionará para decenas de petabytes. Hay una variedad de posibles enfoques con sus propios pros y contras, que se discutirán a continuación. Es una buena idea utilizar varios enfoques en lugar de uno solo para compensar sus diversas deficiencias.
-
-!!! note "Nota"
-    Tenga en cuenta que si realizó una copia de seguridad de algo y nunca intentó restaurarlo, es probable que la restauración no funcione correctamente cuando realmente la necesite (o al menos tomará más tiempo de lo que las empresas pueden tolerar). Por lo tanto, cualquiera que sea el enfoque de copia de seguridad que elija, asegúrese de automatizar el proceso de restauración también y ponerlo en practica en un clúster de ClickHouse de repuesto regularmente.
-
-## Duplicar datos de origen en otro lugar {#duplicating-source-data-somewhere-else}
-
-A menudo, los datos que se ingieren en ClickHouse se entregan a través de algún tipo de cola persistente, como [Acerca de nosotros](https://kafka.apache.org). En este caso, es posible configurar un conjunto adicional de suscriptores que leerá el mismo flujo de datos mientras se escribe en ClickHouse y lo almacenará en almacenamiento en frío en algún lugar. La mayoría de las empresas ya tienen algún almacenamiento en frío recomendado por defecto, que podría ser un almacén de objetos o un sistema de archivos distribuido como [HDFS](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html).
-
-## Instantáneas del sistema de archivos {#filesystem-snapshots}
-
-Algunos sistemas de archivos locales proporcionan funcionalidad de instantánea (por ejemplo, [ZFS](https://en.wikipedia.org/wiki/ZFS)), pero podrían no ser la mejor opción para servir consultas en vivo. Una posible solución es crear réplicas adicionales con este tipo de sistema de archivos y excluirlas del [Distribuido](../engines/table-engines/special/distributed.md) tablas que se utilizan para `SELECT` consulta. Las instantáneas en tales réplicas estarán fuera del alcance de cualquier consulta que modifique los datos. Como beneficio adicional, estas réplicas podrían tener configuraciones de hardware especiales con más discos conectados por servidor, lo que sería rentable.
-
-## Método de codificación de datos: {#clickhouse-copier}
-
-[Método de codificación de datos:](utilities/clickhouse-copier.md) es una herramienta versátil que se creó inicialmente para volver a dividir tablas de tamaño petabyte. También se puede usar con fines de copia de seguridad y restauración porque copia datos de forma fiable entre tablas y clústeres de ClickHouse.
-
-Para volúmenes de datos más pequeños, un simple `INSERT INTO ... SELECT ...` a tablas remotas podría funcionar también.
-
-## Manipulaciones con piezas {#manipulations-with-parts}
-
-ClickHouse permite usar la consulta `ALTER TABLE ... FREEZE PARTITION ...` para crear una copia local de particiones de tabla. Esto se implementa utilizando enlaces duros a la carpeta `/var/lib/clickhouse/shadow/`, por lo que generalmente no consume espacio adicional en disco para datos antiguos. Las copias creadas de archivos no son manejadas por el servidor ClickHouse, por lo que puede dejarlas allí: tendrá una copia de seguridad simple que no requiere ningún sistema externo adicional, pero seguirá siendo propenso a problemas de hardware. Por esta razón, es mejor copiarlos de forma remota en otra ubicación y luego eliminar las copias locales. Los sistemas de archivos distribuidos y los almacenes de objetos siguen siendo una buena opción para esto, pero los servidores de archivos conectados normales con una capacidad lo suficientemente grande podrían funcionar también (en este caso, la transferencia ocurrirá a través del sistema de archivos de red o tal vez [rsync](https://en.wikipedia.org/wiki/Rsync)).
-
-Para obtener más información sobre las consultas relacionadas con las manipulaciones de particiones, consulte [Documentación de ALTER](../sql-reference/statements/alter.md#alter_manipulations-with-partitions).
-
-Una herramienta de terceros está disponible para automatizar este enfoque: [Haga clic en el botón de copia de seguridad](https://github.com/AlexAkulov/clickhouse-backup).

----
-
-# Archivos de configuración {#configuration_files}
-
-ClickHouse admite la administración de configuración de varios archivos. El archivo de configuración del servidor principal es `/etc/clickhouse-server/config.xml`. Otros archivos deben estar en el `/etc/clickhouse-server/config.d` directorio.
-
-!!! note "Nota"
-    Todos los archivos de configuración deben estar en formato XML. Además, deben tener el mismo elemento raíz, generalmente `<yandex>`.
-
-Algunos valores especificados en el archivo de configuración principal se pueden anular en otros archivos de configuración. El `replace` o `remove` se pueden especificar atributos para los elementos de estos archivos de configuración.
-
-Si no se especifica ninguno, combina el contenido de los elementos de forma recursiva, reemplazando los valores de los elementos secundarios duplicados.
-
-Si `replace` se especifica, reemplaza todo el elemento por el especificado.
-
-Si `remove` se especifica, elimina el elemento.
-
-La configuración también puede definir “substitutions”. Si un elemento tiene el `incl` atributo, la sustitución correspondiente del archivo se utilizará como el valor. De forma predeterminada, la ruta al archivo con sustituciones es `/etc/metrika.xml`. Esto se puede cambiar en el [include_from](server-configuration-parameters/settings.md#server_configuration_parameters-include_from) elemento en la configuración del servidor. Los valores de sustitución se especifican en `/yandex/substitution_name` elementos en este archivo. Si una sustitución especificada en `incl` no existe, se registra en el registro. Para evitar que ClickHouse registre las sustituciones que faltan, especifique `optional="true"` atributo (por ejemplo, ajustes para [macro](server-configuration-parameters/settings.md)).
-
-Las sustituciones también se pueden realizar desde ZooKeeper. Para hacer esto, especifique el atributo `from_zk = "/path/to/node"`. El valor del elemento se sustituye por el contenido del nodo en `/path/to/node` en ZooKeeper. También puede colocar un subárbol XML completo en el nodo ZooKeeper y se insertará completamente en el elemento de origen.
-
-El `config.xml` file puede especificar una configuración separada con configuraciones de usuario, perfiles y cuotas. La ruta relativa a esta configuración se establece en el `users_config` elemento. Por defecto, es `users.xml`. Si `users_config` se omite, la configuración de usuario, los perfiles y las cuotas se especifican directamente en `config.xml`.
-
-La configuración de los usuarios se puede dividir en archivos separados similares a `config.xml` y `config.d/`.
-El nombre del directorio se define como `users_config` sin `.xml` postfix concatenado con `.d`.
-Directorio `users.d` se utiliza por defecto, como `users_config` por defecto `users.xml`.
-Por ejemplo, puede tener un archivo de configuración separado para cada usuario como este:
-
-``` bash
-$ cat /etc/clickhouse-server/users.d/alice.xml
-```
-
-``` xml
-<yandex>
-    <users>
-      <alice>
-          <profile>analytics</profile>
-            <networks>
-                  <ip>::/0</ip>
-            </networks>
-          <password_sha256_hex>...</password_sha256_hex>
-          <quota>analytics</quota>
-      </alice>
-    </users>
-</yandex>
-```
-
-Para cada archivo de configuración, el servidor también genera `file-preprocessed.xml` archivos al iniciar. Estos archivos contienen todas las sustituciones y anulaciones completadas, y están destinados para uso informativo. Si se utilizaron sustituciones de ZooKeeper en los archivos de configuración pero ZooKeeper no está disponible en el inicio del servidor, el servidor carga la configuración desde el archivo preprocesado.
-
-El servidor realiza un seguimiento de los cambios en los archivos de configuración, así como archivos y nodos ZooKeeper que se utilizaron al realizar sustituciones y anulaciones, y vuelve a cargar la configuración de los usuarios y clústeres sobre la marcha. Esto significa que puede modificar el clúster, los usuarios y su configuración sin reiniciar el servidor.

-
-# Monitoreo {#monitoring}
-
-Usted puede monitorear:
-
--   Utilización de recursos de hardware.
--   Métricas del servidor ClickHouse.
-
-## Utilización de recursos {#resource-utilization}
-
-ClickHouse no supervisa el estado de los recursos de hardware por sí mismo.
-
-Se recomienda encarecidamente configurar la supervisión para:
-
--   Carga y temperatura en los procesadores.
-
-    Usted puede utilizar [dmesg](https://en.wikipedia.org/wiki/Dmesg), [Turbostat](https://www.linux.org/docs/man8/turbostat.html) u otros instrumentos.
-
--   Utilización del sistema de almacenamiento, RAM y red.
-
-## Métricas del servidor ClickHouse {#clickhouse-server-metrics}
-
-El servidor ClickHouse tiene instrumentos integrados para el monitoreo de estado propio.
-
-Para realizar un seguimiento de los eventos del servidor, use los registros del servidor. Ver el [registrador](server-configuration-parameters/settings.md#server_configuration_parameters-logger) sección del archivo de configuración.
-
-ClickHouse recoge:
-
--   Diferentes métricas de cómo el servidor utiliza recursos computacionales.
--   Estadísticas comunes sobre el procesamiento de consultas.
-
-Puede encontrar métricas en el [sistema.métricas](../operations/system-tables.md#system_tables-metrics), [sistema.evento](../operations/system-tables.md#system_tables-events), y [sistema.asynchronous_metrics](../operations/system-tables.md#system_tables-asynchronous_metrics) tabla.
-
-Puede configurar ClickHouse para exportar métricas a [Grafito](https://github.com/graphite-project). Ver el [Sección de grafito](server-configuration-parameters/settings.md#server_configuration_parameters-graphite) en el archivo de configuración del servidor ClickHouse. Antes de configurar la exportación de métricas, debe configurar Graphite siguiendo sus [guiar](https://graphite.readthedocs.io/en/latest/install.html).
-
-Puede configurar ClickHouse para exportar métricas a [Prometeo](https://prometheus.io). Ver el [Sección Prometheus](server-configuration-parameters/settings.md#server_configuration_parameters-prometheus) en el archivo de configuración del servidor ClickHouse. Antes de configurar la exportación de métricas, debe configurar Prometheus siguiendo su oficial [guiar](https://prometheus.io/docs/prometheus/latest/installation/).
-
-Además, puede supervisar la disponibilidad del servidor a través de la API HTTP. Enviar el `HTTP GET` solicitud de `/ping`. Si el servidor está disponible, responde con `200 OK`.
-
-Para supervisar servidores en una configuración de clúster, debe establecer [max_replica_delay_for_distributed_queries](settings/settings.md#settings-max_replica_delay_for_distributed_queries) parámetro y utilizar el recurso HTTP `/replicas_status`. Una solicitud para `/replicas_status` devoluciones `200 OK` si la réplica está disponible y no se retrasa detrás de las otras réplicas. Si una réplica se retrasa, devuelve `503 HTTP_SERVICE_UNAVAILABLE` con información sobre la brecha.

----
-
-# Analizador de consultas de muestreo {#sampling-query-profiler}
-
-ClickHouse ejecuta el generador de perfiles de muestreo que permite analizar la ejecución de consultas. Utilizando el generador de perfiles puede encontrar rutinas de código fuente que se utilizan con más frecuencia durante la ejecución de la consulta. Puede rastrear el tiempo de CPU y el tiempo de reloj de pared invertido, incluido el tiempo de inactividad.
-
-Para usar el generador de perfiles:
-
--   Configurar el [trace_log](../server-configuration-parameters/settings.md#server_configuration_parameters-trace_log) sección de la configuración del servidor.
-
-    Esta sección configura la [trace_log](../../operations/system-tables.md#system_tables-trace_log) tabla del sistema que contiene los resultados del funcionamiento del generador de perfiles. Está configurado de forma predeterminada. Recuerde que los datos de esta tabla solo son válidos para un servidor en ejecución. Después de reiniciar el servidor, ClickHouse no limpia la tabla y toda la dirección de memoria virtual almacenada puede dejar de ser válida.
-
--   Configurar el [Los resultados de la prueba](../settings/settings.md#query_profiler_cpu_time_period_ns) o [query_profiler_real_time_period_ns](../settings/settings.md#query_profiler_real_time_period_ns) configuración. Ambos ajustes se pueden utilizar simultáneamente.
-
-    Estas opciones le permiten configurar temporizadores del generador de perfiles. Como estos son los ajustes de sesión, puede obtener diferentes frecuencias de muestreo para todo el servidor, usuarios individuales o perfiles de usuario, para su sesión interactiva y para cada consulta individual.
-
-La frecuencia de muestreo predeterminada es una muestra por segundo y tanto la CPU como los temporizadores reales están habilitados. Esta frecuencia permite recopilar suficiente información sobre el clúster ClickHouse. Al mismo tiempo, al trabajar con esta frecuencia, el generador de perfiles no afecta el rendimiento del servidor ClickHouse. Si necesita perfilar cada consulta individual, intente usar una mayor frecuencia de muestreo.
-
-Para analizar el `trace_log` tabla del sistema:
-
--   Instale el `clickhouse-common-static-dbg` paquete. Ver [Instalar desde paquetes DEB](../../getting-started/install.md#install-from-deb-packages).
-
--   Permitir funciones de introspección [allow_introspection_functions](../settings/settings.md#settings-allow_introspection_functions) configuración.
-
-    Por razones de seguridad, las funciones de introspección están deshabilitadas de forma predeterminada.
-
--   Utilice el `addressToLine`, `addressToSymbol` y `demangle` [funciones de la introspección](../../sql-reference/functions/introspection.md) para obtener nombres de funciones y sus posiciones en el código ClickHouse. Para obtener un perfil para alguna consulta, debe agregar datos del `trace_log` tabla. Puede agregar datos por funciones individuales o por los seguimientos de pila completos.
-
-Si necesita visualizar `trace_log` información, intente [Flamegraph](../../interfaces/third-party/gui/#clickhouse-flamegraph) y [Nivel de Cifrado WEP](https://github.com/laplab/clickhouse-speedscope).
-
-## Ejemplo {#example}
-
-En este ejemplo nos:
-
--   Filtrado `trace_log` datos por un identificador de consulta y la fecha actual.
-
--   Agregando por seguimiento de pila.
-
--   Usando funciones de introspección, obtendremos un informe de:
-
-    -   Nombres de símbolos y funciones de código fuente correspondientes.
-    -   Ubicaciones del código fuente de estas funciones.
-

-toc_title: Cuota
----
-
-# Cuota {#quotas}
-
-Las cuotas le permiten limitar el uso de recursos durante un período de tiempo o realizar un seguimiento del uso de recursos.
-Las cuotas se configuran en la configuración del usuario, que generalmente ‘users.xml’.
-
-El sistema también tiene una característica para limitar la complejidad de una sola consulta. Vea la sección “Restrictions on query complexity”).
-
-A diferencia de las restricciones de complejidad de consultas, las cuotas:
-
--   Coloque restricciones en un conjunto de consultas que se pueden ejecutar durante un período de tiempo, en lugar de limitar una sola consulta.
--   Tenga en cuenta los recursos gastados en todos los servidores remotos para el procesamiento de consultas distribuidas.
-
-Veamos la sección del ‘users.xml’ fichero que define las cuotas.
-
-``` xml
-<!-- Quotas -->
-<quotas>
-    <!-- Quota name. -->
-    <default>
-        <!-- Restrictions for a time period. You can set many intervals with different restrictions. -->
-        <interval>
-            <!-- Length of the interval. -->
-            <duration>3600</duration>
-
-            <!-- Unlimited. Just collect data for the specified time interval. -->
-            <queries>0</queries>
-            <errors>0</errors>
-            <result_rows>0</result_rows>
-            <read_rows>0</read_rows>
-            <execution_time>0</execution_time>
-        </interval>
-    </default>
-```
-
-De forma predeterminada, la cuota realiza un seguimiento del consumo de recursos para cada hora, sin limitar el uso.
-El consumo de recursos calculado para cada intervalo se envía al registro del servidor después de cada solicitud.
-
-``` xml
-<statbox>
-    <!-- Restrictions for a time period. You can set many intervals with different restrictions. -->
-    <interval>
-        <!-- Length of the interval. -->
-        <duration>3600</duration>
-
-        <queries>1000</queries>
-        <errors>100</errors>
-        <result_rows>1000000000</result_rows>
-        <read_rows>100000000000</read_rows>
-        <execution_time>900</execution_time>
-    </interval>
-
-    <interval>
-        <duration>86400</duration>
-
-        <queries>10000</queries>
-        <errors>1000</errors>
-        <result_rows>5000000000</result_rows>
-        <read_rows>500000000000</read_rows>
-        <execution_time>7200</execution_time>
-    </interval>
-</statbox>
-```
-
-Para el ‘statbox’ Las restricciones se establecen por cada hora y por cada 24 horas (86.400 segundos). El intervalo de tiempo se cuenta, a partir de un momento fijo definido por la implementación en el tiempo. En otras palabras, el intervalo de 24 horas no necesariamente comienza a medianoche.
-
-Cuando finaliza el intervalo, se borran todos los valores recopilados. Para la siguiente hora, el cálculo de la cuota comienza de nuevo.
-
-Estas son las cantidades que se pueden restringir:
-
-`queries` – The total number of requests.
-
-`errors` – The number of queries that threw an exception.
-
-`result_rows` – The total number of rows given as a result.
-
-`read_rows` – The total number of source rows read from tables for running the query on all remote servers.
-
-`execution_time` – The total query execution time, in seconds (wall time).
-
-Si se excede el límite durante al menos un intervalo de tiempo, se lanza una excepción con un texto sobre qué restricción se excedió, para qué intervalo y cuándo comienza el nuevo intervalo (cuando se pueden enviar consultas nuevamente).
-
-Las cuotas pueden usar el “quota key” característica para informar sobre los recursos para múltiples claves de forma independiente. Aquí hay un ejemplo de esto:
-
-``` xml
-<!-- For the global reports designer. -->
-<web_global>
-    <!-- keyed – The quota_key "key" is passed in the query parameter,
-            and the quota is tracked separately for each key value.
-        For example, you can pass a Yandex.Metrica username as the key,
-            so the quota will be counted separately for each username.
-        Using keys makes sense only if quota_key is transmitted by the program, not by a user.
-
-        You can also write <keyed_by_ip />, so the IP address is used as the quota key.
-        (But keep in mind that users can change the IPv6 address fairly easily.)
-    -->
-    <keyed />
-```
-
-La cuota se asigna a los usuarios ‘users’ sección de la configuración. Vea la sección “Access rights”.
-
-Para el procesamiento de consultas distribuidas, los importes acumulados se almacenan en el servidor del solicitante. Entonces, si el usuario va a otro servidor, la cuota allí “start over”.
-
-Cuando se reinicia el servidor, las cuotas se restablecen.

----
-
-# Requisito {#requirements}
-
-## CPU {#cpu}
-
-Para la instalación desde paquetes deb precompilados, utilice una CPU con arquitectura x86_64 y soporte para las instrucciones de SSE 4.2. Para ejecutar ClickHouse con procesadores que no admiten SSE 4.2 o tienen arquitectura AArch64 o PowerPC64LE, debe compilar ClickHouse a partir de fuentes.
-
-ClickHouse implementa el procesamiento de datos paralelo y utiliza todos los recursos de hardware disponibles. Al elegir un procesador, tenga en cuenta que ClickHouse funciona de manera más eficiente en configuraciones con un gran número de núcleos pero con una velocidad de reloj más baja que en configuraciones con menos núcleos y una velocidad de reloj más alta. Por ejemplo, 16 núcleos con 2600 MHz es preferible a 8 núcleos con 3600 MHz.
-
-Se recomienda usar **Impulso de Turbo** y **hiper-threading** tecnología. Mejora significativamente el rendimiento con una carga de trabajo típica.
-
-## RAM {#ram}
-
-Recomendamos utilizar un mínimo de 4 GB de RAM para realizar consultas no triviales. El servidor ClickHouse puede ejecutarse con una cantidad mucho menor de RAM, pero requiere memoria para procesar consultas.
-
-El volumen requerido de RAM depende de:
-
--   La complejidad de las consultas.
--   La cantidad de datos que se procesan en las consultas.
-
-Para calcular el volumen requerido de RAM, debe estimar el tamaño de los datos temporales para [GROUP BY](../sql-reference/statements/select/group-by.md#select-group-by-clause), [DISTINCT](../sql-reference/statements/select/distinct.md#select-distinct), [JOIN](../sql-reference/statements/select/join.md#select-join) y otras operaciones que utilice.
-
-ClickHouse puede usar memoria externa para datos temporales. Ver [GROUP BY en memoria externa](../sql-reference/statements/select/group-by.md#select-group-by-in-external-memory) para más detalles.
-
-## Archivo de intercambio {#swap-file}
-
-Deshabilite el archivo de intercambio para entornos de producción.
-
-## Subsistema de almacenamiento {#storage-subsystem}
-
-Necesita tener 2 GB de espacio libre en disco para instalar ClickHouse.
-
-El volumen de almacenamiento requerido para sus datos debe calcularse por separado. La evaluación debe incluir:
-
--   Estimación del volumen de datos.
-
-    Puede tomar una muestra de los datos y obtener el tamaño promedio de una fila de ella. Luego multiplique el valor por el número de filas que planea almacenar.
-
--   El coeficiente de compresión de datos.
-
-    Para estimar el coeficiente de compresión de datos, cargue una muestra de sus datos en ClickHouse y compare el tamaño real de los datos con el tamaño de la tabla almacenada. Por ejemplo, los datos de clickstream generalmente se comprimen de 6 a 10 veces.
-
-Para calcular el volumen final de datos que se almacenarán, aplique el coeficiente de compresión al volumen de datos estimado. Si planea almacenar datos en varias réplicas, multiplique el volumen estimado por el número de réplicas.
-
-## Red {#network}
-
-Si es posible, use redes de 10G o clase superior.
-
-El ancho de banda de la red es fundamental para procesar consultas distribuidas con una gran cantidad de datos intermedios. Además, la velocidad de la red afecta a los procesos de replicación.
-
-## Software {#software}
-
-ClickHouse está desarrollado principalmente para la familia de sistemas operativos Linux. La distribución de Linux recomendada es Ubuntu. El `tzdata` paquete debe ser instalado en el sistema.
-
-ClickHouse también puede funcionar en otras familias de sistemas operativos. Ver detalles en el [Primeros pasos](../getting-started/index.md) sección de la documentación.

-**Ejemplo**
-
-``` xml
-<logger>
-    <level>trace</level>

-        <port>2181</port>
-    </node>
-```
-
-      The `index` attribute specifies the node order when trying to connect to the ZooKeeper cluster.
-
--   `session_timeout` — Maximum timeout for the client session in milliseconds.
--   `root` — The [Znode](http://zookeeper.apache.org/doc/r3.5.5/zookeeperOver.html#Nodes+and+ephemeral+nodes) que se utiliza como la raíz de los znodes utilizados por el servidor ClickHouse. Opcional.

-
-## use_minimalistic_part_header_in_zookeeper {#server-settings-use_minimalistic_part_header_in_zookeeper}
-
-Método de almacenamiento para encabezados de parte de datos en ZooKeeper.
-
-Esta configuración sólo se aplica a `MergeTree` familia. Se puede especificar:
-
--   A nivel mundial en el [merge_tree](#server_configuration_parameters-merge_tree) sección de la `config.xml` file.
-
-    ClickHouse utiliza la configuración para todas las tablas del servidor. Puede cambiar la configuración en cualquier momento. Las tablas existentes cambian su comportamiento cuando cambia la configuración.
-
--   Para cada tabla.
-
-    Al crear una tabla, especifique la correspondiente [ajuste del motor](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table). El comportamiento de una tabla existente con esta configuración no cambia, incluso si la configuración global cambia.
-
-**Valores posibles**
-
--   0 — Functionality is turned off.
--   1 — Functionality is turned on.
-
-Si `use_minimalistic_part_header_in_zookeeper = 1`, entonces [repetición](../../engines/table-engines/mergetree-family/replication.md) las tablas almacenan los encabezados de las partes de datos de forma compacta `znode`. Si la tabla contiene muchas columnas, este método de almacenamiento reduce significativamente el volumen de los datos almacenados en Zookeeper.
-
-!!! attention "Atención"
-    Después de aplicar `use_minimalistic_part_header_in_zookeeper = 1`, no puede degradar el servidor ClickHouse a una versión que no admite esta configuración. Tenga cuidado al actualizar ClickHouse en servidores de un clúster. No actualice todos los servidores a la vez. Es más seguro probar nuevas versiones de ClickHouse en un entorno de prueba o solo en unos pocos servidores de un clúster.
-
-      Data part headers already stored with this setting can't be restored to their previous (non-compact) representation.
-
-**Valor predeterminado:** 0.

-
-**Valor predeterminado**: 15.
-
-## access_control_path {#access_control_path}
-
-Ruta de acceso a una carpeta donde un servidor ClickHouse almacena configuraciones de usuario y rol creadas por comandos SQL.
-
-Valor predeterminado: `/var/lib/clickhouse/access/`.

-Las restricciones se definen como las siguientes:
-
-``` xml
-<profiles>
-  <user_name>
-    <constraints>
-      <setting_name_1>
-        <min>lower_boundary</min>
-      </setting_name_1>
-      <setting_name_2>
-        <max>upper_boundary</max>
-      </setting_name_2>
-      <setting_name_3>
-        <min>lower_boundary</min>
-        <max>upper_boundary</max>
-      </setting_name_3>
-      <setting_name_4>
-        <readonly/>
-      </setting_name_4>
-    </constraints>
-  </user_name>
-</profiles>
-```
-
-Si el usuario intenta violar las restricciones, se lanza una excepción y la configuración no se cambia.
-Se admiten tres tipos de restricciones: `min`, `max`, `readonly`. El `min` y `max` Las restricciones especifican los límites superior e inferior para una configuración numérica y se pueden usar en combinación. El `readonly` constraint especifica que el usuario no puede cambiar la configuración correspondiente en absoluto.
-
-**Ejemplo:** Dejar `users.xml` incluye líneas:
-
-``` xml
-<profiles>
-  <default>
-    <max_memory_usage>10000000000</max_memory_usage>
-    <force_index_by_date>0</force_index_by_date>
-    ...
-    <constraints>
-      <max_memory_usage>
-        <min>5000000000</min>
-        <max>20000000000</max>
-      </max_memory_usage>
-      <force_index_by_date>
-        <readonly/>
-      </force_index_by_date>
-    </constraints>
-  </default>
-</profiles>
-```
-
-Las siguientes consultas arrojan excepciones:
-
-``` sql
-SET max_memory_usage=20000000001;
-SET max_memory_usage=4999999999;
-SET force_index_by_date=1;
-```
-
-``` text
-Code: 452, e.displayText() = DB::Exception: Setting max_memory_usage should not be greater than 20000000000.
-Code: 452, e.displayText() = DB::Exception: Setting max_memory_usage should not be less than 5000000000.
-Code: 452, e.displayText() = DB::Exception: Setting force_index_by_date should not be changed.
-```
-
-**Nota:** el `default` perfil tiene un manejo especial: todas las restricciones definidas para el `default` profile se convierten en las restricciones predeterminadas, por lo que restringen a todos los usuarios hasta que se anulan explícitamente para estos usuarios.

-# Configuración {#session-settings-intro}
-
-Hay varias maneras de realizar todos los ajustes descritos en esta sección de documentación.
-
-Los ajustes se configuran en capas, por lo que cada capa subsiguiente redefine los ajustes anteriores.
-
-Formas de configurar los ajustes, por orden de prioridad:
-
--   Ajustes en el `users.xml` archivo de configuración del servidor.
-
-    Establecer en el elemento `<profiles>`.
-
--   Configuración de la sesión.
-
-    Enviar `SET setting=value` desde el cliente de consola ClickHouse en modo interactivo.
-    Del mismo modo, puede utilizar sesiones ClickHouse en el protocolo HTTP. Para hacer esto, debe especificar el `session_id` Parámetro HTTP.
-
--   Configuración de consulta.
-
-    -   Al iniciar el cliente de consola de ClickHouse en modo no interactivo, establezca el parámetro de inicio `--setting=value`.
-    -   Al usar la API HTTP, pase los parámetros CGI (`URL?setting_1=value&setting_2=value...`).
-
-Los ajustes que solo se pueden realizar en el archivo de configuración del servidor no se tratan en esta sección.

----
-
-# Permisos para consultas {#permissions_for_queries}
-
-Las consultas en ClickHouse se pueden dividir en varios tipos:
-
-1.  Leer consultas de datos: `SELECT`, `SHOW`, `DESCRIBE`, `EXISTS`.
-2.  Escribir consultas de datos: `INSERT`, `OPTIMIZE`.
-3.  Cambiar la consulta de configuración: `SET`, `USE`.
-4.  [DDL](https://en.wikipedia.org/wiki/Data_definition_language) consulta: `CREATE`, `ALTER`, `RENAME`, `ATTACH`, `DETACH`, `DROP` `TRUNCATE`.
-5.  `KILL QUERY`.
-
-La siguiente configuración regula los permisos de usuario según el tipo de consulta:
-
--   [sólo lectura](#settings_readonly) — Restricts permissions for all types of queries except DDL queries.
--   [Método de codificación de datos:](#settings_allow_ddl) — Restricts permissions for DDL queries.
-
-`KILL QUERY` se puede realizar con cualquier configuración.
-
-## sólo lectura {#settings_readonly}
-
-Restringe los permisos para leer datos, escribir datos y cambiar las consultas de configuración.
-
-Vea cómo las consultas se dividen en tipos [arriba](#permissions_for_queries).
-
-Valores posibles:
-
--   0 — All queries are allowed.
--   1 — Only read data queries are allowed.
--   2 — Read data and change settings queries are allowed.
-
-Después de configurar `readonly = 1` el usuario no puede cambiar `readonly` y `allow_ddl` configuración en la sesión actual.
-
-Cuando se utiliza el `GET` método en el [Interfaz HTTP](../../interfaces/http.md), `readonly = 1` se establece automáticamente. Para modificar los datos, `POST` método.
-
-Configuración `readonly = 1` prohibir al usuario cambiar todas las configuraciones. Hay una manera de prohibir al usuario
-de cambiar sólo ajustes específicos, para más detalles ver [restricciones en la configuración](constraints-on-settings.md).
-
-Valor predeterminado: 0
-
-## Método de codificación de datos: {#settings_allow_ddl}

-Vea cómo las consultas se dividen en tipos [arriba](#permissions_for_queries).
-
-Valores posibles:
-
--   0 — DDL queries are not allowed.

-toc_title: Restricciones en la complejidad de consultas
----
-
-# Restricciones en la complejidad de consultas {#restrictions-on-query-complexity}
-
-Las restricciones en la complejidad de la consulta forman parte de la configuración.
-Se utilizan para proporcionar una ejecución más segura desde la interfaz de usuario.
-Casi todas las restricciones solo se aplican a `SELECT`. Para el procesamiento de consultas distribuidas, las restricciones se aplican en cada servidor por separado.
-
-ClickHouse comprueba las restricciones para las partes de datos, no para cada fila. Significa que puede exceder el valor de restricción con el tamaño de la parte de datos.
-
-Restricciones en el “maximum amount of something” puede tomar el valor 0, lo que significa “unrestricted”.
-La mayoría de las restricciones también tienen un ‘overflow_mode’ establecer, lo que significa qué hacer cuando se excede el límite.
-Puede tomar uno de dos valores: `throw` o `break`. Las restricciones en la agregación (group_by_overflow_mode) también tienen el valor `any`.
-
-`throw` – Throw an exception (default).
-
-`break` – Stop executing the query and return the partial result, as if the source data ran out.
-
-`any (only for group_by_overflow_mode)` – Continuing aggregation for the keys that got into the set, but don't add new keys to the set.
-
-## Método de codificación de datos: {#settings_max_memory_usage}
-
-La cantidad máxima de RAM que se utiliza para ejecutar una consulta en un único servidor.
-
-En el archivo de configuración predeterminado, el máximo es de 10 GB.
-
-La configuración no tiene en cuenta el volumen de memoria disponible ni el volumen total de memoria en la máquina.
-La restricción se aplica a una sola consulta dentro de un único servidor.
-Usted puede utilizar `SHOW PROCESSLIST` para ver el consumo de memoria actual para cada consulta.
-Además, el consumo máximo de memoria se rastrea para cada consulta y se escribe en el registro.
-
-El uso de memoria no se supervisa para los estados de ciertas funciones agregadas.
-
-El uso de memoria no se realiza un seguimiento completo de los estados de las funciones agregadas `min`, `max`, `any`, `anyLast`, `argMin`, `argMax` de `String` y `Array` argumento.
-
-El consumo de memoria también está restringido por los parámetros `max_memory_usage_for_user` y `max_memory_usage_for_all_queries`.
-
-## Max_memory_usage_for_user {#max-memory-usage-for-user}
-
-La cantidad máxima de RAM que se utilizará para ejecutar las consultas de un usuario en un único servidor.
-
-Los valores predeterminados se definen en [Configuración.h](https://github.com/ClickHouse/ClickHouse/blob/master/src/Core/Settings.h#L288). De forma predeterminada, el importe no está restringido (`max_memory_usage_for_user = 0`).
-
-Ver también la descripción de [Método de codificación de datos:](#settings_max_memory_usage).
-
-## Todos los derechos reservados {#max-memory-usage-for-all-queries}
-
-La cantidad máxima de RAM que se utilizará para ejecutar todas las consultas en un único servidor.
-
-Los valores predeterminados se definen en [Configuración.h](https://github.com/ClickHouse/ClickHouse/blob/master/src/Core/Settings.h#L289). De forma predeterminada, el importe no está restringido (`max_memory_usage_for_all_queries = 0`).
-
-Ver también la descripción de [Método de codificación de datos:](#settings_max_memory_usage).
-
-## ¿Qué puedes encontrar en Neodigit {#max-rows-to-read}
-
-Las siguientes restricciones se pueden verificar en cada bloque (en lugar de en cada fila). Es decir, las restricciones se pueden romper un poco.
-
-Un número máximo de filas que se pueden leer de una tabla al ejecutar una consulta.
-
-## ¿Qué puedes encontrar en Neodigit {#max-bytes-to-read}
-
-Un número máximo de bytes (datos sin comprimir) que se pueden leer de una tabla al ejecutar una consulta.
-
-## Método de codificación de datos: {#read-overflow-mode}
-
-Qué hacer cuando el volumen de datos leídos excede uno de los límites: ‘throw’ o ‘break’. Por defecto, throw.
-
-## Método de codificación de datos: {#settings-max-rows-to-group-by}
-
-Un número máximo de claves únicas recibidas de la agregación. Esta configuración le permite limitar el consumo de memoria al agregar.
-
-## Grupo_by_overflow_mode {#group-by-overflow-mode}
-
-Qué hacer cuando el número de claves únicas para la agregación excede el límite: ‘throw’, ‘break’, o ‘any’. Por defecto, throw.
-Uso de la ‘any’ valor le permite ejecutar una aproximación de GROUP BY. La calidad de esta aproximación depende de la naturaleza estadística de los datos.
-
-## max_bytes_before_external_group_by {#settings-max_bytes_before_external_group_by}
-
-Habilita o deshabilita la ejecución de `GROUP BY` en la memoria externa. Ver [GROUP BY en memoria externa](../../sql-reference/statements/select/group-by.md#select-group-by-in-external-memory).
-
-Valores posibles:
-
--   Volumen máximo de RAM (en bytes) que puede ser utilizado por el único [GROUP BY](../../sql-reference/statements/select/group-by.md#select-group-by-clause) operación.
--   0 — `GROUP BY` en la memoria externa deshabilitada.
-
-Valor predeterminado: 0.
-
-## Método de codificación de datos: {#max-rows-to-sort}
-
-Un número máximo de filas antes de ordenar. Esto le permite limitar el consumo de memoria al ordenar.
-
-## Método de codificación de datos: {#max-bytes-to-sort}
-
-Un número máximo de bytes antes de ordenar.
-
-## sort_overflow_mode {#sort-overflow-mode}
-
-Qué hacer si el número de filas recibidas antes de ordenar excede uno de los límites: ‘throw’ o ‘break’. Por defecto, throw.
-
-## max_result_rows {#setting-max_result_rows}
-
-Límite en el número de filas en el resultado. También se comprueba si hay subconsultas y en servidores remotos cuando se ejecutan partes de una consulta distribuida.
-
-## max_result_bytes {#max-result-bytes}
-
-Límite en el número de bytes en el resultado. Lo mismo que el ajuste anterior.
-
-## result_overflow_mode {#result-overflow-mode}
-
-Qué hacer si el volumen del resultado excede uno de los límites: ‘throw’ o ‘break’. Por defecto, throw.
-
-Utilizar ‘break’ es similar a usar LIMIT. `Break` interrumpe la ejecución sólo en el nivel de bloque. Esto significa que la cantidad de filas devueltas es mayor que [max_result_rows](#setting-max_result_rows), múltiplo de [max_block_size](settings.md#setting-max_block_size) y depende de [max_threads](settings.md#settings-max_threads).
-
-Ejemplo:
-
-``` sql
-SET max_threads = 3, max_block_size = 3333;
-SET max_result_rows = 3334, result_overflow_mode = 'break';
-
-SELECT *
-FROM numbers_mt(100000)
-FORMAT Null;
-```
-
-Resultado:
-
-``` text
-6666 rows in set. ...
-```
-
-## max_execution_time {#max-execution-time}
-
-Tiempo máximo de ejecución de la consulta en segundos.
-En este momento, no se comprueba una de las etapas de clasificación, o al fusionar y finalizar funciones agregadas.
-
-## timeout_overflow_mode {#timeout-overflow-mode}
-
-Qué hacer si la consulta se ejecuta más de ‘max_execution_time’: ‘throw’ o ‘break’. Por defecto, throw.
-
-## Método de codificación de datos: {#min-execution-speed}
-
-Velocidad de ejecución mínima en filas por segundo. Comprobado en cada bloque de datos cuando ‘timeout_before_checking_execution_speed’ expirar. Si la velocidad de ejecución es menor, se produce una excepción.
-
-## Todos los derechos reservados {#min-execution-speed-bytes}
-
-Un número mínimo de bytes de ejecución por segundo. Comprobado en cada bloque de datos cuando ‘timeout_before_checking_execution_speed’ expirar. Si la velocidad de ejecución es menor, se produce una excepción.
-
-## Max_execution_speed {#max-execution-speed}
-
-Un número máximo de filas de ejecución por segundo. Comprobado en cada bloque de datos cuando ‘timeout_before_checking_execution_speed’ expirar. Si la velocidad de ejecución es alta, la velocidad de ejecución se reducirá.
-
-## Max_execution_speed_bytes {#max-execution-speed-bytes}
-
-Un número máximo de bytes de ejecución por segundo. Comprobado en cada bloque de datos cuando ‘timeout_before_checking_execution_speed’ expirar. Si la velocidad de ejecución es alta, la velocidad de ejecución se reducirá.
-
-## Tiempo de espera antes de comprobar_ejecución_velocidad {#timeout-before-checking-execution-speed}
-
-Comprueba que la velocidad de ejecución no sea demasiado lenta (no menos de ‘min_execution_speed’), después de que el tiempo especificado en segundos haya expirado.
-
-## Max_columns_to_read {#max-columns-to-read}
-
-Un número máximo de columnas que se pueden leer de una tabla en una sola consulta. Si una consulta requiere leer un mayor número de columnas, produce una excepción.
-
-## max_temporary_columns {#max-temporary-columns}
-
-Un número máximo de columnas temporales que se deben mantener en la memoria RAM al mismo tiempo cuando se ejecuta una consulta, incluidas las columnas constantes. Si hay más columnas temporales que esto, arroja una excepción.
-
-## max_temporary_non_const_columns {#max-temporary-non-const-columns}
-
-Lo mismo que ‘max_temporary_columns’, pero sin contar columnas constantes.
-Tenga en cuenta que las columnas constantes se forman con bastante frecuencia cuando se ejecuta una consulta, pero requieren aproximadamente cero recursos informáticos.
-
-## max_subquery_depth {#max-subquery-depth}
-
-Profundidad máxima de anidamiento de subconsultas. Si las subconsultas son más profundas, se produce una excepción. De forma predeterminada, 100.
-
-## max_pipeline_depth {#max-pipeline-depth}
-
-Profundidad máxima de la tubería. Corresponde al número de transformaciones que realiza cada bloque de datos durante el procesamiento de consultas. Contado dentro de los límites de un único servidor. Si la profundidad de la canalización es mayor, se produce una excepción. Por defecto, 1000.
-
-## max_ast_depth {#max-ast-depth}
-
-Profundidad máxima de anidamiento de un árbol sintáctico de consulta. Si se supera, se produce una excepción.
-En este momento, no se verifica durante el análisis, sino solo después de analizar la consulta. Es decir, se puede crear un árbol sintáctico demasiado profundo durante el análisis, pero la consulta fallará. Por defecto, 1000.
-
-## max_ast_elements {#max-ast-elements}
-
-Un número máximo de elementos en un árbol sintáctico de consulta. Si se supera, se produce una excepción.
-De la misma manera que la configuración anterior, se verifica solo después de analizar la consulta. De forma predeterminada, 50.000.
-
-## Método de codificación de datos: {#max-rows-in-set}
-
-Un número máximo de filas para un conjunto de datos en la cláusula IN creada a partir de una subconsulta.
-
-## Método de codificación de datos: {#max-bytes-in-set}
-
-Número máximo de bytes (datos sin comprimir) utilizados por un conjunto en la cláusula IN creada a partir de una subconsulta.
-
-## set_overflow_mode {#set-overflow-mode}
-
-Qué hacer cuando la cantidad de datos excede uno de los límites: ‘throw’ o ‘break’. Por defecto, throw.
-
-## Método de codificación de datos: {#max-rows-in-distinct}
-
-Un número máximo de filas diferentes al usar DISTINCT.
-
-## Método de codificación de datos: {#max-bytes-in-distinct}
-
-Un número máximo de bytes utilizados por una tabla hash cuando se utiliza DISTINCT.
-
-## distinct_overflow_mode {#distinct-overflow-mode}
-
-Qué hacer cuando la cantidad de datos excede uno de los límites: ‘throw’ o ‘break’. Por defecto, throw.
-
-## max_rows_to_transfer {#max-rows-to-transfer}
-
-Un número máximo de filas que se pueden pasar a un servidor remoto o guardar en una tabla temporal cuando se utiliza GLOBAL IN.
-
-## max_bytes_to_transfer {#max-bytes-to-transfer}
-
-Un número máximo de bytes (datos sin comprimir) que se pueden pasar a un servidor remoto o guardar en una tabla temporal cuando se utiliza GLOBAL IN.
-
-## transfer_overflow_mode {#transfer-overflow-mode}
-
-Qué hacer cuando la cantidad de datos excede uno de los límites: ‘throw’ o ‘break’. Por defecto, throw.
-
-## Método de codificación de datos: {#settings-max_rows_in_join}
-
-Limita el número de filas de la tabla hash que se utiliza al unir tablas.
-
-Esta configuración se aplica a [SELECT … JOIN](../../sql-reference/statements/select/join.md#select-join) operaciones y la [Unir](../../engines/table-engines/special/join.md) motor de mesa.
-
-Si una consulta contiene varias combinaciones, ClickHouse comprueba esta configuración para cada resultado intermedio.
-
-ClickHouse puede proceder con diferentes acciones cuando se alcanza el límite. Utilice el [join_overflow_mode](#settings-join_overflow_mode) configuración para elegir la acción.
-
-Valores posibles:
-
--   Entero positivo.
--   0 — Unlimited number of rows.
-
-Valor predeterminado: 0.
-
-## Método de codificación de datos: {#settings-max_bytes_in_join}
-
-Limita el tamaño en bytes de la tabla hash utilizada al unir tablas.
-
-Esta configuración se aplica a [SELECT … JOIN](../../sql-reference/statements/select/join.md#select-join) operaciones y [Unirse al motor de tabla](../../engines/table-engines/special/join.md).
-
-Si la consulta contiene combinaciones, ClickHouse comprueba esta configuración para cada resultado intermedio.
-
-ClickHouse puede proceder con diferentes acciones cuando se alcanza el límite. Utilizar [join_overflow_mode](#settings-join_overflow_mode) para elegir la acción.
-
-Valores posibles:
-
--   Entero positivo.
--   0 — Memory control is disabled.
-
-Valor predeterminado: 0.
-
-## join_overflow_mode {#settings-join_overflow_mode}
-
-Define qué acción realiza ClickHouse cuando se alcanza cualquiera de los siguientes límites de combinación:
-
--   [Método de codificación de datos:](#settings-max_bytes_in_join)
--   [Método de codificación de datos:](#settings-max_rows_in_join)
-
-Valores posibles:
-
--   `THROW` — ClickHouse throws an exception and breaks operation.
--   `BREAK` — ClickHouse breaks operation and doesn't throw an exception.
-
-Valor predeterminado: `THROW`.
-
-**Ver también**
-
--   [Cláusula JOIN](../../sql-reference/statements/select/join.md#select-join)
--   [Unirse al motor de tabla](../../engines/table-engines/special/join.md)
-
-## max_partitions_per_insert_block {#max-partitions-per-insert-block}
-
-Limita el número máximo de particiones en un único bloque insertado.
-
--   Entero positivo.
--   0 — Unlimited number of partitions.
-
-Valor predeterminado: 100.
-
-**Detalles**
-
-Al insertar datos, ClickHouse calcula el número de particiones en el bloque insertado. Si el número de particiones es mayor que `max_partitions_per_insert_block`, ClickHouse lanza una excepción con el siguiente texto:
-
-> “Too many partitions for single INSERT block (more than” ¿Cómo puedo hacerlo? “). The limit is controlled by ‘max_partitions_per_insert_block’ setting. A large number of partitions is a common misconception. It will lead to severe negative performance impact, including slow server startup, slow INSERT queries and slow SELECT queries. Recommended total number of partitions for a table is under 1000..10000. Please note, that partitioning is not intended to speed up SELECT queries (ORDER BY key is sufficient to make range queries fast). Partitions are intended for data manipulation (DROP PARTITION, etc).”

-# Perfiles de configuración {#settings-profiles}
-
-Un perfil de configuración es una colección de configuraciones agrupadas con el mismo nombre.
-
-!!! note "Información"
-    ClickHouse también es compatible [Flujo de trabajo controlado por SQL](../access-rights.md#access-control) para administrar perfiles de configuración. Recomendamos usarlo.
-
-Un perfil puede tener cualquier nombre. El perfil puede tener cualquier nombre. Puede especificar el mismo perfil para diferentes usuarios. Lo más importante que puede escribir en el perfil de configuración es `readonly=1`, que asegura el acceso de sólo lectura.
-
-Los perfiles de configuración pueden heredar unos de otros. Para usar la herencia, indique una o varias `profile` configuraciones antes de las demás configuraciones que se enumeran en el perfil. En caso de que se defina una configuración en diferentes perfiles, se utiliza la última definida.
-
-Para aplicar todos los ajustes de un perfil, establezca el `profile` configuración.
-
-Ejemplo:
-
-Instale el `web` perfil.
-
-``` sql
-SET profile = 'web'
-```
-
-Los perfiles de configuración se declaran en el archivo de configuración del usuario. Esto suele ser `users.xml`.
-
-Ejemplo:
-
-``` xml
-<!-- Settings profiles -->
-<profiles>
-    <!-- Default settings -->
-    <default>
-        <!-- The maximum number of threads when running a single query. -->

-    </default>
-
-    <!-- Settings for quries from the user interface -->
-    <web>
-        <max_rows_to_read>1000000000</max_rows_to_read>
-        <max_bytes_to_read>100000000000</max_bytes_to_read>
-
-        <max_rows_to_group_by>1000000</max_rows_to_group_by>
-        <group_by_overflow_mode>any</group_by_overflow_mode>

-
-El ejemplo especifica dos perfiles: `default` y `web`.
-
-El `default` tiene un propósito especial: siempre debe estar presente y se aplica al iniciar el servidor. En otras palabras, el `default` perfil contiene la configuración predeterminada.
-
-El `web` profile es un perfil regular que se puede establecer utilizando el `SET` consulta o utilizando un parámetro URL en una consulta HTTP.

-# Configuración del usuario {#user-settings}
-
-El `users` sección de la `user.xml` el archivo de configuración contiene la configuración del usuario.
-
-!!! note "Información"
-    ClickHouse también es compatible [Flujo de trabajo controlado por SQL](../access-rights.md#access-control) para la gestión de usuarios. Recomendamos usarlo.
-
-Estructura del `users` apartado:
-
-``` xml
-<users>
-    <!-- If user name was not specified, 'default' user is used. -->
-    <user_name>
-        <password></password>
-        <!-- Or -->
-        <password_sha256_hex></password_sha256_hex>

-        </databases>
-    </user_name>
-    <!-- Other users settings -->
-</users>
-```
-
-### user_name/contraseña {#user-namepassword}
-
-La contraseña se puede especificar en texto sin formato o en SHA256 (formato hexagonal).
-
--   Para asignar una contraseña en texto sin formato (**no se recomienda**), colóquelo en un `password` elemento.
-
-    Por ejemplo, `<password>qwerty</password>`. La contraseña se puede dejar en blanco.
-
-<a id="password_sha256_hex"></a>
-
--   Para asignar una contraseña utilizando su hash SHA256, colóquela en un `password_sha256_hex` elemento.
-
-    Por ejemplo, `<password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex>`.
-
-    Ejemplo de cómo generar una contraseña desde el shell:
-
-          PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
-
-    La primera línea del resultado es la contraseña. La segunda línea es el hash SHA256 correspondiente.
-
-<a id="password_double_sha1_hex"></a>
-
--   Para la compatibilidad con los clientes MySQL, la contraseña se puede especificar en doble hash SHA1. Colóquelo en `password_double_sha1_hex` elemento.
-
-    Por ejemplo, `<password_double_sha1_hex>08b4a0f1de6ad37da17359e592c8d74788a83eb0</password_double_sha1_hex>`.
-
-    Ejemplo de cómo generar una contraseña desde el shell:
-
-          PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha1sum | tr -d '-' | xxd -r -p | sha1sum | tr -d '-'
-
-    La primera línea del resultado es la contraseña. La segunda línea es el hash SHA1 doble correspondiente.
-
-### access_management {#access_management-user-setting}
-
-Esta configuración habilita deshabilita el uso de [control de acceso y gestión de cuentas](../access-rights.md#access-control) para el usuario.
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 0.
-
-### user_name/redes {#user-namenetworks}
-
-Lista de redes desde las que el usuario puede conectarse al servidor ClickHouse.
-
-Cada elemento de la lista puede tener una de las siguientes formas:
-
--   `<ip>` — IP address or network mask.
-
-    Ejemplos: `213.180.204.3`, `10.0.0.1/8`, `10.0.0.1/255.255.255.0`, `2a02:6b8::3`, `2a02:6b8::3/64`, `2a02:6b8::3/ffff:ffff:ffff:ffff::`.
-
--   `<host>` — Hostname.
-
-    Ejemplo: `example01.host.ru`.
-
-    Para comprobar el acceso, se realiza una consulta DNS y todas las direcciones IP devueltas se comparan con la dirección del mismo nivel.
-
--   `<host_regexp>` — Regular expression for hostnames.
-
-    Ejemplo, `^example\d\d-\d\d-\d\.host\.ru$`
-
-    Para comprobar el acceso, un [Consulta de DNS PTR](https://en.wikipedia.org/wiki/Reverse_DNS_lookup) se realiza para la dirección del mismo nivel y luego se aplica la expresión regular especificada. A continuación, se realiza otra consulta DNS para los resultados de la consulta PTR y todas las direcciones recibidas se comparan con la dirección del mismo nivel. Recomendamos encarecidamente que regexp termine con $ .
-
-Todos los resultados de las solicitudes DNS se almacenan en caché hasta que el servidor se reinicia.
-
-**Ejemplos**
-
-Para abrir el acceso del usuario desde cualquier red, especifique:
-
-``` xml
-<ip>::/0</ip>
-```
-
-!!! warning "Advertencia"
-    No es seguro abrir el acceso desde cualquier red a menos que tenga un firewall configurado correctamente o el servidor no esté conectado directamente a Internet.
-
-Para abrir el acceso solo desde localhost, especifique:
-
-``` xml
-<ip>::1</ip>
-<ip>127.0.0.1</ip>
-```
-
-### user_name/perfil {#user-nameprofile}
-
-Puede asignar un perfil de configuración para el usuario. Los perfiles de configuración se configuran en una sección separada del `users.xml` file. Para obtener más información, consulte [Perfiles de configuración](settings-profiles.md).
-
-### user_name/cuota {#user-namequota}
-
-Las cuotas le permiten realizar un seguimiento o limitar el uso de recursos durante un período de tiempo. Las cuotas se configuran en el `quotas`
-sección de la `users.xml` archivo de configuración.
-
-Puede asignar un conjunto de cuotas para el usuario. Para obtener una descripción detallada de la configuración de las cuotas, consulte [Cuota](../quotas.md#quotas).
-
-### nombre_usuario/bases de datos {#user-namedatabases}
-
-En esta sección, puede limitar las filas devueltas por ClickHouse para `SELECT` consultas realizadas por el usuario actual, implementando así la seguridad básica a nivel de fila.
-
-**Ejemplo**
-
-La siguiente configuración obliga a que el usuario `user1` sólo puede ver las filas de `table1` como resultado de `SELECT` consultas, donde el valor de la `id` campo es 1000.
-
-``` xml
-<user1>
-    <databases>
-        <database_name>
-            <table1>
-                <filter>id = 1000</filter>
-            </table1>
-        </database_name>
-    </databases>
-</user1>
-```
-
-El `filter` puede ser cualquier expresión que resulte en un [UInt8](../../sql-reference/data-types/int-uint.md)-tipo de valor. Por lo general, contiene comparaciones y operadores lógicos. Filas de `database_name.table1` donde los resultados del filtro a 0 no se devuelven para este usuario. El filtrado es incompatible con `PREWHERE` operaciones y desactiva `WHERE→PREWHERE` optimización.

-# Configuración {#settings}
-
-## distributed_product_mode {#distributed-product-mode}
-
-Cambia el comportamiento de [subconsultas distribuidas](../../sql-reference/operators/in.md).
-
-ClickHouse applies this setting when the query contains the product of distributed tables, i.e. when the query for a distributed table contains a non-GLOBAL subquery for the distributed table.
-
-Restricción:
-
--   Solo se aplica para las subconsultas IN y JOIN.
--   Solo si la sección FROM utiliza una tabla distribuida que contiene más de un fragmento.
--   Si la subconsulta se refiere a una tabla distribuida que contiene más de un fragmento.
--   No se usa para un valor de tabla [remoto](../../sql-reference/table-functions/remote.md) función.
-
-Valores posibles:
-
--   `deny` — Default value. Prohibits using these types of subqueries (returns the “Double-distributed in/JOIN subqueries is denied” salvedad).
--   `local` — Replaces the database and table in the subquery with local ones for the destination server (shard), leaving the normal `IN`/`JOIN.`
--   `global` — Replaces the `IN`/`JOIN` consulta con `GLOBAL IN`/`GLOBAL JOIN.`
--   `allow` — Allows the use of these types of subqueries.
-
-## enable_optimize_predicate_expression {#enable-optimize-predicate-expression}
-
-Activa el pushdown de predicado en `SELECT` consulta.
-
-La extracción de predicados puede reducir significativamente el tráfico de red para consultas distribuidas.
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 1.
-
-Uso
-
-Considere las siguientes consultas:
-
-1.  `SELECT count() FROM test_table WHERE date = '2018-10-10'`
-2.  `SELECT count() FROM (SELECT * FROM test_table) WHERE date = '2018-10-10'`
-
-Si `enable_optimize_predicate_expression = 1`, entonces el tiempo de ejecución de estas consultas es igual porque se aplica ClickHouse `WHERE` a la subconsulta al procesarla.
-
-Si `enable_optimize_predicate_expression = 0`, entonces el tiempo de ejecución de la segunda consulta es mucho más largo, porque el `WHERE` cláusula se aplica a todos los datos después de que finalice la subconsulta.
-
-## fallback_to_stale_replicas_for_distributed_queries {#settings-fallback_to_stale_replicas_for_distributed_queries}
-
-Fuerza una consulta a una réplica obsoleta si los datos actualizados no están disponibles. Ver [Replicación](../../engines/table-engines/mergetree-family/replication.md).
-
-ClickHouse selecciona la más relevante de las réplicas obsoletas de la tabla.
-
-Se utiliza al realizar `SELECT` desde una tabla distribuida que apunta a tablas replicadas.
-
-De forma predeterminada, 1 (habilitado).
-
-## Fecha de nacimiento {#settings-force_index_by_date}
-
-Deshabilita la ejecución de consultas si el índice no se puede usar por fecha.
-
-Funciona con tablas de la familia MergeTree.
-
-Si `force_index_by_date=1`, ClickHouse comprueba si la consulta tiene una condición de clave de fecha que se puede usar para restringir intervalos de datos. Si no hay una condición adecuada, arroja una excepción. Sin embargo, no comprueba si la condición reduce la cantidad de datos a leer. Por ejemplo, la condición `Date != ' 2000-01-01 '` es aceptable incluso cuando coincide con todos los datos de la tabla (es decir, ejecutar la consulta requiere un escaneo completo). Para obtener más información acerca de los intervalos de datos en las tablas MergeTree, vea [Método de codificación de datos:](../../engines/table-engines/mergetree-family/mergetree.md).
-
-## force_primary_key {#force-primary-key}
-
-Deshabilita la ejecución de consultas si no es posible la indexación mediante la clave principal.
-
-Funciona con tablas de la familia MergeTree.
-
-Si `force_primary_key=1`, ClickHouse comprueba si la consulta tiene una condición de clave principal que se puede usar para restringir rangos de datos. Si no hay una condición adecuada, arroja una excepción. Sin embargo, no comprueba si la condición reduce la cantidad de datos a leer. Para obtener más información acerca de los intervalos de datos en las tablas MergeTree, consulte [Método de codificación de datos:](../../engines/table-engines/mergetree-family/mergetree.md).
-
-## Formato_esquema {#format-schema}
-
-Este parámetro es útil cuando se utilizan formatos que requieren una definición de esquema, como [Cap'n Proto](https://capnproto.org/) o [Protobuf](https://developers.google.com/protocol-buffers/). El valor depende del formato.
-
-## fsync_metadata {#fsync-metadata}
-
-Habilita o deshabilita [fsync](http://pubs.opengroup.org/onlinepubs/9699919799/functions/fsync.html) al escribir `.sql` file. Habilitado de forma predeterminada.
-
-Tiene sentido desactivarlo si el servidor tiene millones de pequeñas tablas que se crean y destruyen constantemente.
-
-## enable_http_compression {#settings-enable_http_compression}
-
-Habilita o deshabilita la compresión de datos en la respuesta a una solicitud HTTP.
-
-Para obtener más información, lea el [Descripción de la interfaz HTTP](../../interfaces/http.md).
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 0.
-
-## http_zlib_compression_level {#settings-http_zlib_compression_level}
-
-Establece el nivel de compresión de datos en la respuesta a una solicitud HTTP si [enable_http_compression = 1](#settings-enable_http_compression).
-
-Valores posibles: Números del 1 al 9.
-
-Valor predeterminado: 3.
-
-## http_native_compression_disable_checksumming_on_decompress {#settings-http_native_compression_disable_checksumming_on_decompress}
-
-Habilita o deshabilita la verificación de suma de comprobación al descomprimir los datos HTTP POST del cliente. Se usa solo para el formato de compresión nativa ClickHouse (no se usa con `gzip` o `deflate`).
-
-Para obtener más información, lea el [Descripción de la interfaz HTTP](../../interfaces/http.md).
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 0.
-
-## send_progress_in_http_headers {#settings-send_progress_in_http_headers}
-
-Habilita o deshabilita `X-ClickHouse-Progress` Encabezados de respuesta HTTP en `clickhouse-server` respuesta.
-
-Para obtener más información, lea el [Descripción de la interfaz HTTP](../../interfaces/http.md).
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 0.
-
-## Nombre de la red inalámbrica (SSID): {#setting-max_http_get_redirects}
-
-Limita el número máximo de saltos de redirección HTTP GET para [URL](../../engines/table-engines/special/url.md)-mesas de motor. La configuración se aplica a ambos tipos de tablas: las creadas por [CREATE TABLE](../../sql-reference/statements/create.md#create-table-query) consulta y por el [URL](../../sql-reference/table-functions/url.md) función de la tabla.
-
-Valores posibles:
-
--   Cualquier número entero positivo de saltos.
--   0 — No hops allowed.
-
-Valor predeterminado: 0.
-
-## Entrada_format_allow_errors_num {#settings-input_format_allow_errors_num}
-
-Establece el número máximo de errores aceptables al leer desde formatos de texto (CSV, TSV, etc.).
-
-El valor predeterminado es 0.
-
-Siempre emparejarlo con `input_format_allow_errors_ratio`.
-
-Si se produjo un error al leer filas, pero el contador de errores sigue siendo menor que `input_format_allow_errors_num`, ClickHouse ignora la fila y pasa a la siguiente.
-
-Si ambos `input_format_allow_errors_num` y `input_format_allow_errors_ratio` se exceden, ClickHouse lanza una excepción.
-
-## Entrada_format_allow_errors_ratio {#settings-input_format_allow_errors_ratio}
-
-Establece el porcentaje máximo de errores permitidos al leer desde formatos de texto (CSV, TSV, etc.).
-El porcentaje de errores se establece como un número de punto flotante entre 0 y 1.
-
-El valor predeterminado es 0.
-
-Siempre emparejarlo con `input_format_allow_errors_num`.
-
-Si se produjo un error al leer filas, pero el contador de errores sigue siendo menor que `input_format_allow_errors_ratio`, ClickHouse ignora la fila y pasa a la siguiente.
-
-Si ambos `input_format_allow_errors_num` y `input_format_allow_errors_ratio` se exceden, ClickHouse lanza una excepción.
-
-## input_format_values_interpret_expressions {#settings-input_format_values_interpret_expressions}
-
-Habilita o deshabilita el analizador SQL completo si el analizador de secuencias rápidas no puede analizar los datos. Esta configuración sólo se utiliza para [Valor](../../interfaces/formats.md#data-format-values) formato en la inserción de datos. Para obtener más información sobre el análisis de sintaxis, consulte [Sintaxis](../../sql-reference/syntax.md) apartado.
-
-Valores posibles:
-
--   0 — Disabled.
-
-    En este caso, debe proporcionar datos con formato. Ver el [Formato](../../interfaces/formats.md) apartado.
-
--   1 — Enabled.
-
-    En este caso, puede usar una expresión SQL como valor, pero la inserción de datos es mucho más lenta de esta manera. Si inserta solo datos con formato, ClickHouse se comporta como si el valor de configuración fuera 0.
-
-Valor predeterminado: 1.
-
-Ejemplo de uso
-
-Inserte el [FechaHora](../../sql-reference/data-types/datetime.md) valor de tipo con los diferentes ajustes.
-
-``` sql
-SET input_format_values_interpret_expressions = 0;
-INSERT INTO datetime_t VALUES (now())
-```
-
-``` text
-Exception on client:
-Code: 27. DB::Exception: Cannot parse input: expected ) before: now()): (at row 1)
-```
-
-``` sql
-SET input_format_values_interpret_expressions = 1;
-INSERT INTO datetime_t VALUES (now())
-```
-
-``` text
-Ok.
-```
-
-La última consulta es equivalente a la siguiente:
-
-``` sql
-SET input_format_values_interpret_expressions = 0;
-INSERT INTO datetime_t SELECT now()
-```
-
-``` text
-Ok.
-```
-
-## input_format_values_deduce_templates_of_expressions {#settings-input_format_values_deduce_templates_of_expressions}
-
-Habilita o deshabilita la deducción de plantilla para expresiones SQL en [Valor](../../interfaces/formats.md#data-format-values) formato. Permite analizar e interpretar expresiones en `Values` mucho más rápido si las expresiones en filas consecutivas tienen la misma estructura. ClickHouse intenta deducir la plantilla de una expresión, analizar las siguientes filas utilizando esta plantilla y evaluar la expresión en un lote de filas analizadas correctamente.
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 1.
-
-Para la siguiente consulta:
-
-``` sql
-INSERT INTO test VALUES (lower('Hello')), (lower('world')), (lower('INSERT')), (upper('Values')), ...
-```
-
--   Si `input_format_values_interpret_expressions=1` y `format_values_deduce_templates_of_expressions=0`, las expresiones se interpretan por separado para cada fila (esto es muy lento para un gran número de filas).
--   Si `input_format_values_interpret_expressions=0` y `format_values_deduce_templates_of_expressions=1`, las expresiones en la primera, segunda y tercera filas se analizan usando la plantilla `lower(String)` e interpretados juntos, la expresión en la cuarta fila se analiza con otra plantilla (`upper(String)`).
--   Si `input_format_values_interpret_expressions=1` y `format_values_deduce_templates_of_expressions=1`, lo mismo que en el caso anterior, pero también permite la alternativa a la interpretación de expresiones por separado si no es posible deducir la plantilla.
-
-## Entrada_format_values_accurate_types_of_literals {#settings-input-format-values-accurate-types-of-literals}
-
-Esta configuración sólo se utiliza cuando `input_format_values_deduce_templates_of_expressions = 1`. Puede suceder que las expresiones para alguna columna tengan la misma estructura, pero contengan literales numéricos de diferentes tipos, por ejemplo
-
-``` sql
-(..., abs(0), ...),             -- UInt64 literal
-(..., abs(3.141592654), ...),   -- Float64 literal
-(..., abs(-1), ...),            -- Int64 literal
-```
-
-Valores posibles:
-
--   0 — Disabled.
-
-    In this case, ClickHouse may use a more general type for some literals (e.g., `Float64` o `Int64` en lugar de `UInt64` para `42`), pero puede causar problemas de desbordamiento y precisión.
-
--   1 — Enabled.
-
-    En este caso, ClickHouse comprueba el tipo real de literal y utiliza una plantilla de expresión del tipo correspondiente. En algunos casos, puede ralentizar significativamente la evaluación de expresiones en `Values`.
-
-Valor predeterminado: 1.
-
-## Entrada_format_defaults_for_omitted_fields {#session_settings-input_format_defaults_for_omitted_fields}
-
-Al realizar `INSERT` consultas, reemplace los valores de columna de entrada omitidos con valores predeterminados de las columnas respectivas. Esta opción sólo se aplica a [JSONEachRow](../../interfaces/formats.md#jsoneachrow), [CSV](../../interfaces/formats.md#csv) y [TabSeparated](../../interfaces/formats.md#tabseparated) formato.
-
-!!! note "Nota"
-    Cuando esta opción está habilitada, los metadatos de la tabla extendida se envían del servidor al cliente. Consume recursos informáticos adicionales en el servidor y puede reducir el rendimiento.
-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 1.
-
-## input_format_tsv_empty_as_default {#settings-input-format-tsv-empty-as-default}
-
-Cuando esté habilitado, reemplace los campos de entrada vacíos en TSV con valores predeterminados. Para expresiones predeterminadas complejas `input_format_defaults_for_omitted_fields` debe estar habilitado también.
-
-Deshabilitado de forma predeterminada.
-
-## input_format_null_as_default {#settings-input-format-null-as-default}
-
-Habilita o deshabilita el uso de valores predeterminados si los datos de entrada `NULL`, pero el tipo de datos de la columna correspondiente en no `Nullable(T)` (para formatos de entrada de texto).
-
-## input_format_skip_unknown_fields {#settings-input-format-skip-unknown-fields}
-
-Habilita o deshabilita omitir la inserción de datos adicionales.
-
-Al escribir datos, ClickHouse produce una excepción si los datos de entrada contienen columnas que no existen en la tabla de destino. Si la omisión está habilitada, ClickHouse no inserta datos adicionales y no lanza una excepción.
-
-Formatos soportados:
-
--   [JSONEachRow](../../interfaces/formats.md#jsoneachrow)

-
-## Entrada_format_with_names_use_header {#settings-input-format-with-names-use-header}
-
-Habilita o deshabilita la comprobación del orden de las columnas al insertar datos.
-
-Para mejorar el rendimiento de la inserción, se recomienda deshabilitar esta comprobación si está seguro de que el orden de columna de los datos de entrada es el mismo que en la tabla de destino.
-
-Formatos soportados:

-
-## Date_time_input_format {#settings-date_time_input_format}
-
-Permite elegir un analizador de la representación de texto de fecha y hora.
-
-La configuración no se aplica a [Funciones de fecha y hora](../../sql-reference/functions/date-time-functions.md).
-
-Valores posibles:
-
--   `'best_effort'` — Enables extended parsing.
-
-    ClickHouse puede analizar el básico `YYYY-MM-DD HH:MM:SS` formato y todo [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) formatos de fecha y hora. Por ejemplo, `'2018-06-08T01:02:03.000Z'`.

-
-## max_block_size {#setting-max_block_size}
-
-En ClickHouse, los datos se procesan mediante bloques (conjuntos de partes de columna). Los ciclos de procesamiento interno para un solo bloque son lo suficientemente eficientes, pero hay gastos notables en cada bloque. El `max_block_size` set es una recomendación para el tamaño del bloque (en un recuento de filas) para cargar desde las tablas. El tamaño del bloque no debe ser demasiado pequeño, por lo que los gastos en cada bloque aún se notan, pero no demasiado grande para que la consulta con LIMIT que se complete después del primer bloque se procese rápidamente. El objetivo es evitar consumir demasiada memoria al extraer un gran número de columnas en múltiples subprocesos y preservar al menos alguna localidad de caché.
-
-Valor predeterminado: 65,536.
-
-Bloquea el tamaño de `max_block_size` no siempre se cargan desde la tabla. Si es obvio que se deben recuperar menos datos, se procesa un bloque más pequeño.
-
-## preferred_block_size_bytes {#preferred-block-size-bytes}
-
-Utilizado para el mismo propósito que `max_block_size`, pero establece el tamaño de bloque recomendado en bytes adaptándolo al número de filas en el bloque.

-
-## Max_insert_block_size {#settings-max_insert_block_size}
-
-El tamaño de los bloques a formar para su inserción en una tabla.
-Esta configuración solo se aplica en los casos en que el servidor forma los bloques.
-Por ejemplo, para un INSERT a través de la interfaz HTTP, el servidor analiza el formato de datos y forma bloques del tamaño especificado.
-Pero al usar clickhouse-client, el cliente analiza los datos en sí, y el ‘max_insert_block_size’ configuración en el servidor no afecta el tamaño de los bloques insertados.
-La configuración tampoco tiene un propósito cuando se usa INSERT SELECT , ya que los datos se insertan usando los mismos bloques que se forman después de SELECT .
-
-Valor predeterminado: 1.048.576.
-
-El valor predeterminado es ligeramente más que `max_block_size`. La razón de esto se debe a que ciertos motores de mesa (`*MergeTree`) formar una parte de datos en el disco para cada bloque insertado, que es una entidad bastante grande. Similar, `*MergeTree` las tablas ordenan los datos durante la inserción y un tamaño de bloque lo suficientemente grande permiten clasificar más datos en la RAM.
-
-## Nombre de la red inalámbrica (SSID): {#min-insert-block-size-rows}
-
-Establece el número mínimo de filas en el bloque que se pueden insertar en una tabla `INSERT` consulta. Los bloques de menor tamaño se aplastan en otros más grandes.
-
-Valores posibles:
-
--   Entero positivo.
--   0 — Squashing disabled.
-
-Valor predeterminado: 1048576.
-
-## Todos los derechos reservados {#min-insert-block-size-bytes}
-
-Establece el número mínimo de bytes en el bloque que se pueden insertar en una tabla `INSERT` consulta. Los bloques de menor tamaño se aplastan en otros más grandes.

-
-## max_replica_delay_for_distributed_queries {#settings-max_replica_delay_for_distributed_queries}
-
-Deshabilita las réplicas rezagadas para consultas distribuidas. Ver [Replicación](../../engines/table-engines/mergetree-family/replication.md).
-
-Establece el tiempo en segundos. Si una réplica tiene un retraso superior al valor establecido, no se utiliza esta réplica.
-
-Valor predeterminado: 300.
-
-Se utiliza al realizar `SELECT` desde una tabla distribuida que apunta a tablas replicadas.
-
-## max_threads {#settings-max_threads}
-
-El número máximo de subprocesos de procesamiento de consultas, excluyendo subprocesos para recuperar datos de servidores ‘max_distributed_connections’ parámetro).
-
-Este parámetro se aplica a los subprocesos que realizan las mismas etapas de la canalización de procesamiento de consultas en paralelo.
-Por ejemplo, al leer desde una tabla, si es posible evaluar expresiones con funciones, filtre con WHERE y preagregue para GROUP BY en paralelo usando al menos ‘max_threads’ número de hilos, entonces ‘max_threads’ se utilizan.
-
-Valor predeterminado: el número de núcleos de CPU físicos.
-
-Si normalmente se ejecuta menos de una consulta SELECT en un servidor a la vez, establezca este parámetro en un valor ligeramente inferior al número real de núcleos de procesador.
-
-Para las consultas que se completan rápidamente debido a un LIMIT, puede establecer un ‘max_threads’. Por ejemplo, si el número necesario de entradas se encuentra en cada bloque y max_threads = 8, entonces se recuperan 8 bloques, aunque hubiera sido suficiente leer solo uno.
-
-Cuanto menor sea el `max_threads` valor, menos memoria se consume.
-
-## Método de codificación de datos: {#settings-max-insert-threads}
-
-El número máximo de subprocesos para ejecutar el `INSERT SELECT` consulta.
-
-Valores posibles:
-
--   0 (or 1) — `INSERT SELECT` sin ejecución paralela.
--   Entero positivo. Más grande que 1.
-
-Valor predeterminado: 0.
-
-Paralelo `INSERT SELECT` sólo tiene efecto si el `SELECT` parte se ejecuta en paralelo, ver [max_threads](#settings-max_threads) configuración.
-Los valores más altos conducirán a un mayor uso de memoria.
-
-## max_compress_block_size {#max-compress-block-size}
-
-El tamaño máximo de bloques de datos sin comprimir antes de comprimir para escribir en una tabla. De forma predeterminada, 1.048.576 (1 MiB). Si se reduce el tamaño, la tasa de compresión se reduce significativamente, la velocidad de compresión y descompresión aumenta ligeramente debido a la localidad de la memoria caché, y se reduce el consumo de memoria. Por lo general, no hay ninguna razón para cambiar esta configuración.
-
-No confunda bloques para la compresión (un fragmento de memoria que consta de bytes) con bloques para el procesamiento de consultas (un conjunto de filas de una tabla).
-
-## Descripción del producto {#min-compress-block-size}
-
-Para [Método de codificación de datos:](../../engines/table-engines/mergetree-family/mergetree.md)" tabla. Para reducir la latencia al procesar consultas, un bloque se comprime al escribir la siguiente marca si su tamaño es al menos ‘min_compress_block_size’. De forma predeterminada, 65.536.
-
-El tamaño real del bloque, si los datos sin comprimir son menores que ‘max_compress_block_size’, no es menor que este valor y no menor que el volumen de datos para una marca.
-
-Veamos un ejemplo. Supongamos que ‘index_granularity’ se estableció en 8192 durante la creación de la tabla.
-
-Estamos escribiendo una columna de tipo UInt32 (4 bytes por valor). Al escribir 8192 filas, el total será de 32 KB de datos. Como min_compress_block_size = 65,536, se formará un bloque comprimido por cada dos marcas.
-
-Estamos escribiendo una columna URL con el tipo String (tamaño promedio de 60 bytes por valor). Al escribir 8192 filas, el promedio será ligeramente inferior a 500 KB de datos. Como esto es más de 65,536, se formará un bloque comprimido para cada marca. En este caso, al leer datos del disco en el rango de una sola marca, los datos adicionales no se descomprimirán.
-
-Por lo general, no hay ninguna razón para cambiar esta configuración.
-
-## max_query_size {#settings-max_query_size}
-
-La parte máxima de una consulta que se puede llevar a la RAM para analizar con el analizador SQL.
-La consulta INSERT también contiene datos para INSERT que es procesado por un analizador de secuencias independiente (que consume O(1) RAM), que no está incluido en esta restricción.
-
-Valor predeterminado: 256 KiB.
-
-## interactive_delay {#interactive-delay}
-
-El intervalo en microsegundos para comprobar si la ejecución de la solicitud se ha cancelado y enviar el progreso.
-
-Valor predeterminado: 100.000 (comprueba la cancelación y envía el progreso diez veces por segundo).
-
-## ¿Cómo puedo hacerlo? {#connect-timeout-receive-timeout-send-timeout}
-
-Tiempos de espera en segundos en el socket utilizado para comunicarse con el cliente.
-
-Valor predeterminado: 10, 300, 300.
-
-## Cancel_http_readonly_queries_on_client_close {#cancel-http-readonly-queries-on-client-close}
-
-Cancels HTTP read-only queries (e.g. SELECT) when a client closes the connection without waiting for the response.
-
-Valor predeterminado: 0
-
-## poll_interval {#poll-interval}
-
-Bloquear en un bucle de espera durante el número especificado de segundos.
-
-Valor predeterminado: 10.
-
-## max_distributed_connections {#max-distributed-connections}
-
-El número máximo de conexiones simultáneas con servidores remotos para el procesamiento distribuido de una única consulta a una única tabla distribuida. Se recomienda establecer un valor no menor que el número de servidores en el clúster.
-
-Valor predeterminado: 1024.
-
-Los siguientes parámetros solo se usan al crear tablas distribuidas (y al iniciar un servidor), por lo que no hay ninguna razón para cambiarlas en tiempo de ejecución.
-
-## Distributed_connections_pool_size {#distributed-connections-pool-size}
-
-El número máximo de conexiones simultáneas con servidores remotos para el procesamiento distribuido de todas las consultas a una única tabla distribuida. Se recomienda establecer un valor no menor que el número de servidores en el clúster.
-
-Valor predeterminado: 1024.
-
-## Conecte_timeout_with_failover_ms {#connect-timeout-with-failover-ms}
-
-El tiempo de espera en milisegundos para conectarse a un servidor remoto para un motor de tablas distribuidas ‘shard’ y ‘replica’ secciones se utilizan en la definición de clúster.
-Si no tiene éxito, se realizan varios intentos para conectarse a varias réplicas.
-
-Valor predeterminado: 50.
-
-## connections_with_failover_max_tries {#connections-with-failover-max-tries}
-
-El número máximo de intentos de conexión con cada réplica para el motor de tablas distribuidas.
-
-Valor predeterminado: 3.
-
-## extremo {#extremes}
-
-Ya sea para contar valores extremos (los mínimos y máximos en columnas de un resultado de consulta). Acepta 0 o 1. De forma predeterminada, 0 (deshabilitado).
-Para obtener más información, consulte la sección “Extreme values”.
-
-## Use_uncompressed_cache {#setting-use_uncompressed_cache}
-
-Si se debe usar una memoria caché de bloques sin comprimir. Acepta 0 o 1. De forma predeterminada, 0 (deshabilitado).
-El uso de la memoria caché sin comprimir (solo para tablas de la familia MergeTree) puede reducir significativamente la latencia y aumentar el rendimiento cuando se trabaja con un gran número de consultas cortas. Habilite esta configuración para los usuarios que envían solicitudes cortas frecuentes. También preste atención al [Uncompressed_cache_size](../server-configuration-parameters/settings.md#server-settings-uncompressed_cache_size) configuration parameter (only set in the config file) – the size of uncompressed cache blocks. By default, it is 8 GiB. The uncompressed cache is filled in as needed and the least-used data is automatically deleted.
-
-Para consultas que leen al menos un volumen algo grande de datos (un millón de filas o más), la memoria caché sin comprimir se desactiva automáticamente para ahorrar espacio para consultas realmente pequeñas. Esto significa que puede mantener el ‘use_uncompressed_cache’ ajuste siempre establecido en 1.
-
-## Reemplazar_running_query {#replace-running-query}
-
-Cuando se utiliza la interfaz HTTP, el ‘query_id’ parámetro puede ser pasado. Se trata de cualquier cadena que sirva como identificador de consulta.
-Si una consulta del mismo usuario ‘query_id’ que ya existe en este momento, el comportamiento depende de la ‘replace_running_query’ parámetro.
-
-`0` (default) – Throw an exception (don't allow the query to run if a query with the same ‘query_id’ ya se está ejecutando).
-
-`1` – Cancel the old query and start running the new one.
-
-El Yandex.Metrica utiliza este parámetro establecido en 1 para implementar sugerencias para las condiciones de segmentación. Después de ingresar el siguiente carácter, si la consulta anterior aún no ha finalizado, debe cancelarse.
-
-## Nombre de la red inalámbrica (SSID): {#stream-flush-interval-ms}
-
-Funciona para tablas con streaming en el caso de un tiempo de espera, o cuando un subproceso genera [Max_insert_block_size](#settings-max_insert_block_size) filas.
-
-El valor predeterminado es 7500.
-
-Cuanto menor sea el valor, más a menudo los datos se vacían en la tabla. Establecer el valor demasiado bajo conduce a un rendimiento deficiente.
-
-## load_balancing {#settings-load_balancing}
-
-Especifica el algoritmo de selección de réplicas que se utiliza para el procesamiento de consultas distribuidas.
-
-ClickHouse admite los siguientes algoritmos para elegir réplicas:
-
--   [Aleatorio](#load_balancing-random) (predeterminada)
--   [Nombre de host más cercano](#load_balancing-nearest_hostname)
--   [En orden](#load_balancing-in_order)
--   [Primero o aleatorio](#load_balancing-first_or_random)
-
-### Aleatorio (por defecto) {#load_balancing-random}
-
-``` sql
-load_balancing = random
-```
-
-El número de errores se cuenta para cada réplica. La consulta se envía a la réplica con el menor número de errores, y si hay varios de estos, a cualquiera de ellos.
-Desventajas: La proximidad del servidor no se tiene en cuenta; si las réplicas tienen datos diferentes, también obtendrá datos diferentes.
-
-### Nombre de host más cercano {#load_balancing-nearest_hostname}
-
-``` sql
-load_balancing = nearest_hostname
-```
-
-The number of errors is counted for each replica. Every 5 minutes, the number of errors is integrally divided by 2. Thus, the number of errors is calculated for a recent time with exponential smoothing. If there is one replica with a minimal number of errors (i.e. errors occurred recently on the other replicas), the query is sent to it. If there are multiple replicas with the same minimal number of errors, the query is sent to the replica with a hostname that is most similar to the server's hostname in the config file (for the number of different characters in identical positions, up to the minimum length of both hostnames).
-
-Por ejemplo, example01-01-1 y example01-01-2.yandex.ru son diferentes en una posición, mientras que example01-01-1 y example01-02-2 difieren en dos lugares.
-Este método puede parecer primitivo, pero no requiere datos externos sobre la topología de red, y no compara las direcciones IP, lo que sería complicado para nuestras direcciones IPv6.
-
-Por lo tanto, si hay réplicas equivalentes, se prefiere la más cercana por nombre.
-También podemos suponer que al enviar una consulta al mismo servidor, en ausencia de fallas, una consulta distribuida también irá a los mismos servidores. Por lo tanto, incluso si se colocan datos diferentes en las réplicas, la consulta devolverá principalmente los mismos resultados.
-
-### En orden {#load_balancing-in_order}
-
-``` sql
-load_balancing = in_order
-```
-
-Se accede a las réplicas con el mismo número de errores en el mismo orden en que se especifican en la configuración.
-Este método es apropiado cuando se sabe exactamente qué réplica es preferible.
-
-### Primero o aleatorio {#load_balancing-first_or_random}
-
-``` sql
-load_balancing = first_or_random
-```
-
-Este algoritmo elige la primera réplica del conjunto o una réplica aleatoria si la primera no está disponible. Es efectivo en configuraciones de topología de replicación cruzada, pero inútil en otras configuraciones.
-
-El `first_or_random` resuelve el problema del algoritmo `in_order` algoritmo. Con `in_order`, si una réplica se cae, la siguiente obtiene una carga doble mientras que las réplicas restantes manejan la cantidad habitual de tráfico. Cuando se utiliza el `first_or_random` algoritmo, la carga se distribuye uniformemente entre las réplicas que todavía están disponibles.
-
-## prefer_localhost_replica {#settings-prefer-localhost-replica}
-
-Habilita/deshabilita el uso preferible de la réplica localhost al procesar consultas distribuidas.
-
-Valores posibles:
-
--   1 — ClickHouse always sends a query to the localhost replica if it exists.
--   0 — ClickHouse uses the balancing strategy specified by the [load_balancing](#settings-load_balancing) configuración.
-
-Valor predeterminado: 1.
-
-!!! warning "Advertencia"
-    Deshabilite esta configuración si usa [max_parallel_replicas](#settings-max_parallel_replicas).
-
-## totals_mode {#totals-mode}
-
-Cómo calcular TOTALS cuando HAVING está presente, así como cuando max_rows_to_group_by y group_by_overflow_mode = ‘any’ están presentes.
-Vea la sección “WITH TOTALS modifier”.
-
-## totals_auto_threshold {#totals-auto-threshold}
-
-El umbral para `totals_mode = 'auto'`.
-Vea la sección “WITH TOTALS modifier”.
-
-## max_parallel_replicas {#settings-max_parallel_replicas}
-
-El número máximo de réplicas para cada fragmento al ejecutar una consulta.
-Para obtener coherencia (para obtener diferentes partes de la misma división de datos), esta opción solo funciona cuando se establece la clave de muestreo.
-El retraso de réplica no está controlado.
-
-## compilar {#compile}
-
-Habilitar la compilación de consultas. De forma predeterminada, 0 (deshabilitado).
-
-La compilación solo se usa para parte de la canalización de procesamiento de consultas: para la primera etapa de agregación (GROUP BY).
-Si se compiló esta parte de la canalización, la consulta puede ejecutarse más rápido debido a la implementación de ciclos cortos y a las llamadas de función agregadas en línea. La mejora del rendimiento máximo (hasta cuatro veces más rápido en casos excepcionales) se ve para consultas con múltiples funciones agregadas simples. Por lo general, la ganancia de rendimiento es insignificante. En casos muy raros, puede ralentizar la ejecución de la consulta.
-
-## min_count_to_compile {#min-count-to-compile}
-
-¿Cuántas veces usar potencialmente un fragmento de código compilado antes de ejecutar la compilación? Por defecto, 3.
-For testing, the value can be set to 0: compilation runs synchronously and the query waits for the end of the compilation process before continuing execution. For all other cases, use values ​​starting with 1. Compilation normally takes about 5-10 seconds.
-Si el valor es 1 o más, la compilación se produce de forma asíncrona en un subproceso independiente. El resultado se utilizará tan pronto como esté listo, incluidas las consultas que se están ejecutando actualmente.
-
-Se requiere código compilado para cada combinación diferente de funciones agregadas utilizadas en la consulta y el tipo de claves en la cláusula GROUP BY.
-The results of the compilation are saved in the build directory in the form of .so files. There is no restriction on the number of compilation results since they don't use very much space. Old results will be used after server restarts, except in the case of a server upgrade – in this case, the old results are deleted.
-
-## output_format_json_quote_64bit_integers {#session_settings-output_format_json_quote_64bit_integers}
-
-Si el valor es true, los enteros aparecen entre comillas cuando se usan los formatos JSON\* Int64 y UInt64 (por compatibilidad con la mayoría de las implementaciones de JavaScript); de lo contrario, los enteros se generan sin las comillas.
-
-## Formato_csv_delimiter {#settings-format_csv_delimiter}
-
-El carácter interpretado como un delimitador en los datos CSV. De forma predeterminada, el delimitador es `,`.
-
-## input_format_csv_unquoted_null_literal_as_null {#settings-input_format_csv_unquoted_null_literal_as_null}
-
-Para el formato de entrada CSV, habilita o deshabilita el análisis de `NULL` como literal (sinónimo de `\N`).
-
-## output_format_csv_crlf_end_of_line {#settings-output-format-csv-crlf-end-of-line}
-
-Utilice el separador de línea de estilo DOS / Windows (CRLF) en CSV en lugar de estilo Unix (LF).
-
-## output_format_tsv_crlf_end_of_line {#settings-output-format-tsv-crlf-end-of-line}

-
-## insert_quorum {#settings-insert_quorum}
-
-Habilita las escrituras de quórum.
-
--   Si `insert_quorum < 2`, las escrituras de quórum están deshabilitadas.
--   Si `insert_quorum >= 2`, las escrituras de quórum están habilitadas.
-
-Valor predeterminado: 0.
-
-Quorum escribe
-
-`INSERT` solo tiene éxito cuando ClickHouse logra escribir correctamente datos en el `insert_quorum` de réplicas durante el `insert_quorum_timeout`. Si por alguna razón el número de réplicas con escrituras exitosas no alcanza el `insert_quorum`, la escritura se considera fallida y ClickHouse eliminará el bloque insertado de todas las réplicas donde los datos ya se han escrito.
-
-Todas las réplicas del quórum son consistentes, es decir, contienen datos de todas las réplicas anteriores `INSERT` consulta. El `INSERT` la secuencia está linealizada.
-
-Al leer los datos escritos desde el `insert_quorum` usted puede utilizar el [select_sequential_consistency](#settings-select_sequential_consistency) opcion.
-
-ClickHouse genera una excepción
-
--   Si el número de réplicas disponibles en el momento de la consulta es `insert_quorum`.
--   En un intento de escribir datos cuando el bloque anterior aún no se ha insertado en el `insert_quorum` de réplicas. Esta situación puede ocurrir si el usuario intenta realizar una `INSERT` antes de la anterior con el `insert_quorum` se ha completado.

-
-Valor predeterminado: 0.
-
-Uso
-
-Cuando se habilita la coherencia secuencial, ClickHouse permite al cliente ejecutar el `SELECT` consulta sólo para aquellas réplicas que contienen datos de todas las `INSERT` consultas ejecutadas con `insert_quorum`. Si el cliente hace referencia a una réplica parcial, ClickHouse generará una excepción. La consulta SELECT no incluirá datos que aún no se hayan escrito en el quórum de réplicas.

-
-Valores posibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valor predeterminado: 1.
-
-De forma predeterminada, los bloques insertados en tablas replicadas `INSERT` declaración se deduplican (ver [Replicación de datos](../../engines/table-engines/mergetree-family/replication.md)).
-
-## deduplicate_blocks_in_dependent_materialized_views {#settings-deduplicate-blocks-in-dependent-materialized-views}
-
-Habilita o deshabilita la comprobación de desduplicación para las vistas materializadas que reciben datos de tablas replicadas\*.
-
-Valores posibles:
-
-      0 — Disabled.
-      1 — Enabled.
-
-Valor predeterminado: 0.
-
-Uso
-
-De forma predeterminada, la desduplicación no se realiza para las vistas materializadas, sino que se realiza en sentido ascendente, en la tabla de origen.
-Si se omite un bloque INSERTed debido a la desduplicación en la tabla de origen, no habrá inserción en las vistas materializadas adjuntas. Este comportamiento existe para permitir la inserción de datos altamente agregados en vistas materializadas, para los casos en que los bloques insertados son los mismos después de la agregación de vistas materializadas pero derivados de diferentes INSERT en la tabla de origen.
-Al mismo tiempo, este comportamiento “breaks” `INSERT` idempotencia. Si una `INSERT` en la mesa principal fue exitoso y `INSERT` into a materialized view failed (e.g. because of communication failure with Zookeeper) a client will get an error and can retry the operation. However, the materialized view won't receive the second insert because it will be discarded by deduplication in the main (source) table. The setting `deduplicate_blocks_in_dependent_materialized_views` permite cambiar este comportamiento. Al reintentar, una vista materializada recibirá la inserción de repetición y realizará la comprobación de desduplicación por sí misma,
-ignorando el resultado de la comprobación para la tabla de origen, e insertará filas perdidas debido a la primera falla.

-## skip_unavailable_shards {#settings-skip_unavailable_shards}
-
-Habilita o deshabilita la omisión silenciosa de fragmentos no disponibles.
-
-El fragmento se considera no disponible si todas sus réplicas no están disponibles. Una réplica no está disponible en los siguientes casos:
-
--   ClickHouse no puede conectarse a la réplica por ningún motivo.
-
-    Al conectarse a una réplica, ClickHouse realiza varios intentos. Si todos estos intentos fallan, la réplica se considera que no está disponible.

-No puede eliminar una tabla del sistema (pero puede realizar DETACH).
-Las tablas del sistema no tienen archivos con datos en el disco o archivos con metadatos. El servidor crea todas las tablas del sistema cuando se inicia.
-Las tablas del sistema son de solo lectura.
-Están ubicados en el ‘system’ base.

-Columna:
-
--   `database` (`String`) - Nombre de la base de datos
--   `table` (`String`) - Nombre de la tabla
--   `engine` (`String`) - Nombre del motor de tabla
--   `is_leader` (`UInt8`) - Si la réplica es la líder.
-    Sólo una réplica a la vez puede ser el líder. El líder es responsable de seleccionar las fusiones de fondo para realizar.
-    Tenga en cuenta que las escrituras se pueden realizar en cualquier réplica que esté disponible y tenga una sesión en ZK, independientemente de si es un líder.
--   `can_become_leader` (`UInt8`) - Si la réplica puede ser elegida como líder.
--   `is_readonly` (`UInt8`) - Si la réplica está en modo de sólo lectura.
-    Este modo se activa si la configuración no tiene secciones con ZooKeeper, si se produce un error desconocido al reinicializar sesiones en ZooKeeper y durante la reinicialización de sesiones en ZooKeeper.
--   `is_session_expired` (`UInt8`) - la sesión con ZooKeeper ha expirado. Básicamente lo mismo que `is_readonly`.
--   `future_parts` (`UInt32`) - El número de partes de datos que aparecerán como resultado de INSERTs o fusiones que aún no se han realizado.
--   `parts_to_check` (`UInt32`) - El número de partes de datos en la cola para la verificación. Una pieza se coloca en la cola de verificación si existe la sospecha de que podría estar dañada.
--   `zookeeper_path` (`String`) - Ruta de acceso a los datos de la tabla en ZooKeeper.
--   `replica_name` (`String`) - Nombre de réplica en ZooKeeper. Diferentes réplicas de la misma tabla tienen diferentes nombres.
--   `replica_path` (`String`) - Ruta de acceso a los datos de réplica en ZooKeeper. Lo mismo que concatenar ‘zookeeper_path/replicas/replica_path’.
--   `columns_version` (`Int32`) - Número de versión de la estructura de la tabla. Indica cuántas veces se realizó ALTER. Si las réplicas tienen versiones diferentes, significa que algunas réplicas aún no han hecho todas las ALTER.
--   `queue_size` (`UInt32`) - Tamaño de la cola para las operaciones en espera de ser realizadas. Las operaciones incluyen insertar bloques de datos, fusiones y otras acciones. Por lo general, coincide con `future_parts`.
--   `inserts_in_queue` (`UInt32`) - Número de inserciones de bloques de datos que deben realizarse. Las inserciones generalmente se replican con bastante rapidez. Si este número es grande, significa que algo anda mal.
--   `merges_in_queue` (`UInt32`) - El número de fusiones en espera de hacerse. A veces las fusiones son largas, por lo que este valor puede ser mayor que cero durante mucho tiempo.
--   `part_mutations_in_queue` (`UInt32`) - El número de mutaciones a la espera de hacerse.
--   `queue_oldest_time` (`DateTime`) - Si `queue_size` mayor que 0, muestra cuándo se agregó la operación más antigua a la cola.
--   `inserts_oldest_time` (`DateTime`) - Ver `queue_oldest_time`
--   `merges_oldest_time` (`DateTime`) - Ver `queue_oldest_time`
--   `part_mutations_oldest_time` (`DateTime`) - Ver `queue_oldest_time`
-
-Las siguientes 4 columnas tienen un valor distinto de cero solo cuando hay una sesión activa con ZK.
-
--   `log_max_index` (`UInt64`) - Número máximo de inscripción en el registro de actividad general.
--   `log_pointer` (`UInt64`) - Número máximo de entrada en el registro de actividad general que la réplica copió en su cola de ejecución, más uno. Si `log_pointer` es mucho más pequeño que `log_max_index`, algo está mal.
--   `last_queue_update` (`DateTime`) - Cuando la cola se actualizó la última vez.
--   `absolute_delay` (`UInt64`) - ¿Qué tan grande retraso en segundos tiene la réplica actual.
--   `total_replicas` (`UInt8`) - El número total de réplicas conocidas de esta tabla.
--   `active_replicas` (`UInt8`) - El número de réplicas de esta tabla que tienen una sesión en ZooKeeper (es decir, el número de réplicas en funcionamiento).
-
-Si solicita todas las columnas, la tabla puede funcionar un poco lentamente, ya que se realizan varias lecturas de ZooKeeper para cada fila.
-Si no solicita las últimas 4 columnas (log_max_index, log_pointer, total_replicas, active_replicas), la tabla funciona rápidamente.
-
-Por ejemplo, puede verificar que todo funcione correctamente de esta manera:
-
-``` sql
-SELECT
-    database,
-    table,
-    is_leader,
-    is_readonly,
-    is_session_expired,
-    future_parts,
-    parts_to_check,
-    columns_version,
-    queue_size,
-    inserts_in_queue,
-    merges_in_queue,
-    log_max_index,
-    log_pointer,
-    total_replicas,
-    active_replicas
-FROM system.replicas
-WHERE
-       is_readonly
-    OR is_session_expired
-    OR future_parts > 20
-    OR parts_to_check > 10
-    OR queue_size > 20
-    OR inserts_in_queue > 10
-    OR log_max_index - log_pointer > 10
-    OR total_replicas < 2
-    OR active_replicas < total_replicas
-```
-
-Si esta consulta no devuelve nada, significa que todo está bien.

-## sistema.mutación {#system_tables-mutations}
-
-La tabla contiene información sobre [mutación](../sql-reference/statements/alter.md#alter-mutations) de las tablas MergeTree y su progreso. Cada comando de mutación está representado por una sola fila. La tabla tiene las siguientes columnas:
-
-**base**, **tabla** - El nombre de la base de datos y la tabla a la que se aplicó la mutación.
-
-**mutation_id** - La identificación de la mutación. Para las tablas replicadas, estos identificadores corresponden a los nombres de znode `<table_path_in_zookeeper>/mutations/` directorio en ZooKeeper. Para las tablas no duplicadas, los ID corresponden a los nombres de archivo en el directorio de datos de la tabla.
-
-**comando** - La cadena de comandos de mutación (la parte de la consulta después de `ALTER TABLE [db.]table`).
-
-**create_time** - Cuando este comando de mutación fue enviado para su ejecución.
-
-**block_numbers.partition_id**, **block_numbers.numero** - Una columna anidada. Para las mutaciones de tablas replicadas, contiene un registro para cada partición: el ID de partición y el número de bloque que fue adquirido por la mutación (en cada partición, solo se mutarán las partes que contienen bloques con números menores que el número de bloque adquirido por la mutación en esa partición). En tablas no replicadas, los números de bloque en todas las particiones forman una sola secuencia. Esto significa que para las mutaciones de tablas no replicadas, la columna contendrá un registro con un solo número de bloque adquirido por la mutación.
-
-**partes_a_do** - El número de partes de datos que deben mutarse para que finalice la mutación.
-
-**is_done** - Es la mutación hecho? Tenga en cuenta que incluso si `parts_to_do = 0` es posible que aún no se haya realizado una mutación de una tabla replicada debido a un INSERT de larga ejecución que creará una nueva parte de datos que deberá mutarse.
-
-Si hubo problemas con la mutación de algunas partes, las siguientes columnas contienen información adicional:
-
-**Método de codificación de datos:** - El nombre de la parte más reciente que no se pudo mutar.
-
-**Método de codificación de datos:** - El momento del fracaso de la mutación de la parte más reciente.
-
-**Método de codificación de datos:** - El mensaje de excepción que causó el error de mutación de parte más reciente.

-toc_title: Recomendaciones de uso
----
-
-# Recomendaciones de uso {#usage-recommendations}
-
-## CPU Scaling Governor {#cpu-scaling-governor}
-
-Utilice siempre el `performance` gobernador de escala. El `on-demand` regulador de escala funciona mucho peor con una demanda constante.
-
-``` bash
-$ echo 'performance' | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
-```
-
-## Limitaciones de la CPU {#cpu-limitations}
-
-Los procesadores pueden sobrecalentarse. Utilizar `dmesg` para ver si la velocidad de reloj de la CPU era limitada debido al sobrecalentamiento.
-La restricción también se puede establecer externamente en el nivel del centro de datos. Usted puede utilizar `turbostat` para controlarlo bajo una carga.
-
-## RAM {#ram}
-
-Para pequeñas cantidades de datos (hasta ~200 GB comprimidos), es mejor usar tanta memoria como el volumen de datos.
-Para grandes cantidades de datos y al procesar consultas interactivas (en línea), debe usar una cantidad razonable de RAM (128 GB o más) para que el subconjunto de datos en caliente quepa en la memoria caché de páginas.
-Incluso para volúmenes de datos de ~ 50 TB por servidor, el uso de 128 GB de RAM mejora significativamente el rendimiento de las consultas en comparación con 64 GB.
-
-No deshabilite el sobrecompromiso. Valor `cat /proc/sys/vm/overcommit_memory` debe ser 0 o 1. Ejecutar
-
-``` bash
-$ echo 0 | sudo tee /proc/sys/vm/overcommit_memory
-```
-
-## Páginas enormes {#huge-pages}
-
-Siempre deshabilite las páginas enormes transparentes. Interfiere con los asignadores de memoria, lo que conduce a una degradación significativa del rendimiento.
-
-``` bash
-$ echo 'never' | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
-```
-
-Utilizar `perf top` para ver el tiempo pasado en el kernel para la administración de memoria.
-Las páginas enormes permanentes tampoco necesitan ser asignadas.
-
-## Subsistema de almacenamiento {#storage-subsystem}
-
-Si su presupuesto le permite usar SSD, use SSD.
-Si no, use HDD. Los discos duros SATA 7200 RPM servirán.
-
-Dar preferencia a una gran cantidad de servidores con discos duros locales sobre un número menor de servidores con estantes de discos conectados.
-Pero para almacenar archivos con consultas raras, los estantes funcionarán.
-
-## RAID {#raid}
-
-Al usar HDD, puede combinar su RAID-10, RAID-5, RAID-6 o RAID-50.
-Para Linux, el software RAID es mejor (con `mdadm`). No recomendamos usar LVM.
-Al crear RAID-10, seleccione el `far` diseño.
-Si su presupuesto lo permite, elija RAID-10.
-
-Si tiene más de 4 discos, utilice RAID-6 (preferido) o RAID-50, en lugar de RAID-5.
-Cuando use RAID-5, RAID-6 o RAID-50, siempre aumente stripe_cache_size, ya que el valor predeterminado generalmente no es la mejor opción.
-
-``` bash
-$ echo 4096 | sudo tee /sys/block/md2/md/stripe_cache_size
-```
-
-Calcule el número exacto a partir del número de dispositivos y el tamaño del bloque, utilizando la fórmula: `2 * num_devices * chunk_size_in_bytes / 4096`.
-
-Un tamaño de bloque de 1024 KB es suficiente para todas las configuraciones RAID.
-Nunca ajuste el tamaño del bloque demasiado pequeño o demasiado grande.
-
-Puede usar RAID-0 en SSD.
-Independientemente del uso de RAID, utilice siempre la replicación para la seguridad de los datos.
-
-Habilite NCQ con una cola larga. Para HDD, elija el programador CFQ, y para SSD, elija noop. No reduzca el ‘readahead’ configuración.
-Para HDD, habilite la memoria caché de escritura.
-
-## Sistema de archivos {#file-system}
-
-Ext4 es la opción más confiable. Establecer las opciones de montaje `noatime, nobarrier`.
-XFS también es adecuado, pero no ha sido probado tan a fondo con ClickHouse.
-La mayoría de los otros sistemas de archivos también deberían funcionar bien. Los sistemas de archivos con asignación retrasada funcionan mejor.
-
-## Núcleo de Linux {#linux-kernel}
-
-No use un kernel de Linux obsoleto.
-
-## Red {#network}
-
-Si está utilizando IPv6, aumente el tamaño de la caché de ruta.
-El kernel de Linux anterior a 3.2 tenía una multitud de problemas con la implementación de IPv6.
-
-Utilice al menos una red de 10 GB, si es posible. 1 Gb también funcionará, pero será mucho peor para parchear réplicas con decenas de terabytes de datos, o para procesar consultas distribuidas con una gran cantidad de datos intermedios.
-
-## ZooKeeper {#zookeeper}
-
-Probablemente ya esté utilizando ZooKeeper para otros fines. Puede usar la misma instalación de ZooKeeper, si aún no está sobrecargada.
-
-It's best to use a fresh version of ZooKeeper – 3.4.9 or later. The version in stable Linux distributions may be outdated.
-
-Nunca debe usar scripts escritos manualmente para transferir datos entre diferentes clústeres de ZooKeeper, ya que el resultado será incorrecto para los nodos secuenciales. Nunca utilice el “zkcopy” utilidad por la misma razón: https://github.com/ksprojects/zkcopy/issues/15
-
-Si desea dividir un clúster ZooKeeper existente en dos, la forma correcta es aumentar el número de sus réplicas y, a continuación, volver a configurarlo como dos clústeres independientes.
-
-No ejecute ZooKeeper en los mismos servidores que ClickHouse. Porque ZooKeeper es muy sensible a la latencia y ClickHouse puede utilizar todos los recursos del sistema disponibles.
-
-Con la configuración predeterminada, ZooKeeper es una bomba de tiempo:
-
-> El servidor ZooKeeper no eliminará archivos de instantáneas y registros antiguos cuando utilice la configuración predeterminada (consulte autopurge), y esto es responsabilidad del operador.
-
-Esta bomba debe ser desactivada.
-
-La configuración ZooKeeper (3.5.1) a continuación se usa en Yandex.Entorno de producción de Métrica al 20 de mayo de 2017:

--   [Procesamiento de consultas](#troubleshooting-does-not-process-queries)
--   [Eficiencia del procesamiento de consultas](#troubleshooting-too-slow)
-
-## Instalación {#troubleshooting-installation-errors}
-
-### No puede obtener paquetes Deb del repositorio ClickHouse con Apt-get {#you-cannot-get-deb-packages-from-clickhouse-repository-with-apt-get}
-
--   Compruebe la configuración del firewall.
--   Si no puede acceder al repositorio por cualquier motivo, descargue los paquetes como se describe en el [Primeros pasos](../getting-started/index.md) artículo e instálelos manualmente usando el `sudo dpkg -i <packages>` comando. También necesitará el `tzdata` paquete.
-
-## Conexión al servidor {#troubleshooting-accepts-no-connections}
-
-Posibles problemas:
-
--   El servidor no se está ejecutando.
--   Parámetros de configuración inesperados o incorrectos.
-
-### El servidor no se está ejecutando {#server-is-not-running}
-
-**Compruebe si el servidor está ejecutado**
-
-Comando:
-
-``` bash
-$ sudo service clickhouse-server status
-```
-
-Si el servidor no se está ejecutando, inícielo con el comando:
-
-``` bash
-$ sudo service clickhouse-server start
-```
-
-**Comprobar registros**
-
-El registro principal de `clickhouse-server` está en `/var/log/clickhouse-server/clickhouse-server.log` predeterminada.
-
-Si el servidor se inició correctamente, debería ver las cadenas:
-
--   `<Information> Application: starting up.` — Server started.
--   `<Information> Application: Ready for connections.` — Server is running and ready for connections.
-
-Si `clickhouse-server` error de inicio con un error de configuración, debería ver el `<Error>` cadena con una descripción de error. Por ejemplo:
-
-``` text
-2019.01.11 15:23:25.549505 [ 45 ] {} <Error> ExternalDictionaries: Failed reloading 'event2id' external dictionary: Poco::Exception. Code: 1000, e.code() = 111, e.displayText() = Connection refused, e.what() = Connection refused
-```
-
-Si no ve un error al final del archivo, revise todo el archivo a partir de la cadena:
-
-``` text
-<Information> Application: starting up.
-```
-
-Si intenta iniciar una segunda instancia de `clickhouse-server` en el servidor, verá el siguiente registro:
-
-``` text
-2019.01.11 15:25:11.151730 [ 1 ] {} <Information> : Starting ClickHouse 19.1.0 with revision 54413
-2019.01.11 15:25:11.154578 [ 1 ] {} <Information> Application: starting up

-Revision: 54413
-
-2019.01.11 15:25:11.156673 [ 1 ] {} <Error> Application: DB::Exception: Cannot lock file ./status. Another server instance in same directory is already running.
-2019.01.11 15:25:11.156682 [ 1 ] {} <Information> Application: shutting down

-2019.01.11 15:25:11.156716 [ 2 ] {} <Information> BaseDaemon: Stop SignalListener thread
-```
-
-**Ver sistema.d registros**
-
-Si no encuentra ninguna información útil en `clickhouse-server` registros o no hay registros, puede ver `system.d` registros usando el comando:
-
-``` bash
-$ sudo journalctl -u clickhouse-server
-```
-
-**Iniciar clickhouse-server en modo interactivo**
-
-``` bash
-$ sudo -u clickhouse /usr/bin/clickhouse-server --config-file /etc/clickhouse-server/config.xml
-```
-
-Este comando inicia el servidor como una aplicación interactiva con parámetros estándar del script de inicio automático. En este modo `clickhouse-server` imprime todos los mensajes de eventos en la consola.
-
-### Parámetros de configuración {#configuration-parameters}
-
-Comprobar:
-
--   Configuración de Docker.
-
-    Si ejecuta ClickHouse en Docker en una red IPv6, asegúrese de que `network=host` se establece.
-
--   Configuración del punto final.
-
-    Comprobar [listen_host](server-configuration-parameters/settings.md#server_configuration_parameters-listen_host) y [Tcp_port](server-configuration-parameters/settings.md#server_configuration_parameters-tcp_port) configuración.
-
-    El servidor ClickHouse acepta conexiones localhost solo de forma predeterminada.
-
--   Configuración del protocolo HTTP.
-
-    Compruebe la configuración del protocolo para la API HTTP.
-
--   Configuración de conexión segura.
-
-    Comprobar:
-
-    -   El [Tcp_port_secure](server-configuration-parameters/settings.md#server_configuration_parameters-tcp_port_secure) configuración.
-    -   Ajustes para [Sertificados SSL](server-configuration-parameters/settings.md#server_configuration_parameters-openssl).
-
-    Utilice los parámetros adecuados mientras se conecta. Por ejemplo, utilice el `port_secure` parámetro con `clickhouse_client`.
-
--   Configuración del usuario.
-
-    Es posible que esté utilizando el nombre de usuario o la contraseña incorrectos.
-
-## Procesamiento de consultas {#troubleshooting-does-not-process-queries}
-
-Si ClickHouse no puede procesar la consulta, envía una descripción de error al cliente. En el `clickhouse-client` obtienes una descripción del error en la consola. Si está utilizando la interfaz HTTP, ClickHouse envía la descripción del error en el cuerpo de la respuesta. Por ejemplo:
-
-``` bash
-$ curl 'http://localhost:8123/' --data-binary "SELECT a"
-Code: 47, e.displayText() = DB::Exception: Unknown identifier: a. Note that there are no tables (FROM clause) in your query, context: required_names: 'a' source_tables: table_aliases: private_aliases: column_aliases: public_columns: 'a' masked_columns: array_join_columns: source_columns: , e.what() = DB::Exception
-```
-
-Si empiezas `clickhouse-client` con el `stack-trace` parámetro, ClickHouse devuelve el seguimiento de la pila del servidor con la descripción de un error.
-
-Es posible que vea un mensaje sobre una conexión rota. En este caso, puede repetir la consulta. Si la conexión se rompe cada vez que realiza la consulta, compruebe si hay errores en los registros del servidor.
-
-## Eficiencia del procesamiento de consultas {#troubleshooting-too-slow}
-
-Si ve que ClickHouse funciona demasiado lentamente, debe perfilar la carga en los recursos del servidor y la red para sus consultas.
-
-Puede utilizar la utilidad clickhouse-benchmark para crear perfiles de consultas. Muestra el número de consultas procesadas por segundo, el número de filas procesadas por segundo y percentiles de tiempos de procesamiento de consultas.

-# Actualización de ClickHouse {#clickhouse-update}
-
-Si se instaló ClickHouse desde paquetes deb, ejecute los siguientes comandos en el servidor:
-
-``` bash
-$ sudo apt-get update
-$ sudo apt-get install clickhouse-client clickhouse-server
-$ sudo service clickhouse-server restart
-```
-
-Si ha instalado ClickHouse utilizando algo distinto de los paquetes deb recomendados, utilice el método de actualización adecuado.
-
-ClickHouse no admite una actualización distribuida. La operación debe realizarse consecutivamente en cada servidor separado. No actualice todos los servidores de un clúster simultáneamente, o el clúster no estará disponible durante algún tiempo.

-# Sistema abierto {#clickhouse-benchmark}
-
-Se conecta a un servidor ClickHouse y envía repetidamente las consultas especificadas.
-
-Sintaxis:
-
-``` bash
-$ echo "single query" | clickhouse-benchmark [keys]
-```
-
-o
-
-``` bash
-$ clickhouse-benchmark [keys] <<< "single query"
-```
-
-Si desea enviar un conjunto de consultas, cree un archivo de texto y coloque cada consulta en la cadena individual de este archivo. Por ejemplo:
-
-``` sql
-SELECT * FROM system.numbers LIMIT 10000000
-SELECT 1
-```
-
-Luego pase este archivo a una entrada estándar de `clickhouse-benchmark`.
-
-``` bash
-clickhouse-benchmark [keys] < queries_file
-```
-
-## Claves {#clickhouse-benchmark-keys}
-
--   `-c N`, `--concurrency=N` — Number of queries that `clickhouse-benchmark` se envía simultáneamente. Valor predeterminado: 1.
--   `-d N`, `--delay=N` — Interval in seconds between intermediate reports (set 0 to disable reports). Default value: 1.
--   `-h WORD`, `--host=WORD` — Server host. Default value: `localhost`. Para el [modo de comparación](#clickhouse-benchmark-comparison-mode) puedes usar múltiples `-h` claves.

-## Modo de comparación {#clickhouse-benchmark-comparison-mode}
-
-`clickhouse-benchmark` puede comparar el rendimiento de dos servidores ClickHouse en ejecución.
-
-Para utilizar el modo de comparación, especifique los puntos finales de ambos servidores `--host`, `--port` claves. Las claves coinciden entre sí por posición en la lista de argumentos, la primera `--host` se empareja con la primera `--port` y así sucesivamente. `clickhouse-benchmark` establece conexiones a ambos servidores, luego envía consultas. Cada consulta dirigida a un servidor seleccionado al azar. Los resultados se muestran para cada servidor por separado.

----
-
-# Método de codificación de datos: {#clickhouse-copier}
-
-Copia datos de las tablas de un clúster en tablas de otro (o del mismo) clúster.
-
-Puede ejecutar varios `clickhouse-copier` instancias en diferentes servidores para realizar el mismo trabajo. ZooKeeper se utiliza para sincronizar los procesos.
-
-Después de comenzar, `clickhouse-copier`:
-
--   Se conecta a ZooKeeper y recibe:
-
-    -   Copia de trabajos.
-    -   El estado de los trabajos de copia.
-
--   Realiza los trabajos.
-
-    Cada proceso en ejecución elige el “closest” el fragmento del clúster de origen y copia los datos en el clúster de destino, reafirmando los datos si es necesario.
-
-`clickhouse-copier` realiza un seguimiento de los cambios en ZooKeeper y los aplica sobre la marcha.
-
-Para reducir el tráfico de red, recomendamos ejecutar `clickhouse-copier` en el mismo servidor donde se encuentran los datos de origen.
-
-## Ejecución de Clickhouse-copiadora {#running-clickhouse-copier}
-
-La utilidad debe ejecutarse manualmente:
-
-``` bash
-$ clickhouse-copier copier --daemon --config zookeeper.xml --task-path /task/path --base-dir /path/to/dir
-```
-
-Parámetros:
-
--   `daemon` — Starts `clickhouse-copier` en modo daemon.
--   `config` — The path to the `zookeeper.xml` con los parámetros para la conexión a ZooKeeper.
--   `task-path` — The path to the ZooKeeper node. This node is used for syncing `clickhouse-copier` procesos y tareas de almacenamiento. Las tareas se almacenan en `$task-path/description`.
--   `task-file` — Optional path to file with task configuration for initial upload to ZooKeeper.
--   `task-upload-force` — Force upload `task-file` incluso si el nodo ya existe.
--   `base-dir` — The path to logs and auxiliary files. When it starts, `clickhouse-copier` crear `clickhouse-copier_YYYYMMHHSS_<PID>` subdirectorios en `$base-dir`. Si se omite este parámetro, los directorios se crean en el directorio donde `clickhouse-copier` se puso en marcha.
-
-## Formato de Zookeeper.XML {#format-of-zookeeper-xml}
-
-``` xml

-# clickhouse-local {#clickhouse-local}
-
-El `clickhouse-local` El programa le permite realizar un procesamiento rápido en archivos locales, sin tener que implementar y configurar el servidor ClickHouse.
-
-Acepta datos que representan tablas y las consulta usando [Nombre de la red inalámbrica (SSID):](../../sql-reference/index.md).
-
-`clickhouse-local` utiliza el mismo núcleo que el servidor ClickHouse, por lo que es compatible con la mayoría de las características y el mismo conjunto de formatos y motores de tabla.
-
-Predeterminada `clickhouse-local` no tiene acceso a los datos en el mismo host, pero admite la carga de la configuración del servidor `--config-file` argumento.
-
-!!! warning "Advertencia"
-    No se recomienda cargar la configuración del servidor de producción en `clickhouse-local` Porque los datos pueden dañarse en caso de error humano.
-
-## Uso {#usage}
-
-Uso básico:
-
-``` bash
-$ clickhouse-local --structure "table_structure" --input-format "format_of_incoming_data" -q "query"
-```
-
-Argumento:
-
--   `-S`, `--structure` — table structure for input data.
--   `-if`, `--input-format` — input format, `TSV` predeterminada.
--   `-f`, `--file` — path to data, `stdin` predeterminada.
--   `-q` `--query` — queries to execute with `;` como delimitador.
--   `-N`, `--table` — table name where to put output data, `table` predeterminada.
--   `-of`, `--format`, `--output-format` — output format, `TSV` predeterminada.
--   `--stacktrace` — whether to dump debug output in case of exception.
--   `--verbose` — more details on query execution.
--   `-s` — disables `stderr` tala.
--   `--config-file` — path to configuration file in same format as for ClickHouse server, by default the configuration empty.
--   `--help` — arguments references for `clickhouse-local`.
-
-También hay argumentos para cada variable de configuración de ClickHouse que se usan más comúnmente en lugar de `--config-file`.
-
-## Ejemplos {#examples}
-
-``` bash
-$ echo -e "1,2\n3,4" | clickhouse-local -S "a Int64, b Int64" -if "CSV" -q "SELECT * FROM table"
-Read 2 rows, 32.00 B in 0.000 sec., 5182 rows/sec., 80.97 KiB/sec.
-1   2
-3   4
-```
-
-El ejemplo anterior es el mismo que:
-
-``` bash
-$ echo -e "1,2\n3,4" | clickhouse-local -q "CREATE TABLE table (a Int64, b Int64) ENGINE = File(CSV, stdin); SELECT a, b FROM table; DROP TABLE table"
-Read 2 rows, 32.00 B in 0.000 sec., 4987 rows/sec., 77.93 KiB/sec.
-1   2
-3   4
-```
-
-Ahora vamos a usuario de memoria de salida para cada usuario de Unix:
-
-``` bash
-$ ps aux | tail -n +2 | awk '{ printf("%s\t%s\n", $1, $4) }' | clickhouse-local -S "user String, mem Float64" -q "SELECT user, round(sum(mem), 2) as memTotal FROM table GROUP BY user ORDER BY memTotal DESC FORMAT Pretty"
-```
-
-``` text
-Read 186 rows, 4.15 KiB in 0.035 sec., 5302 rows/sec., 118.34 KiB/sec.
-┏━━━━━━━━━━┳━━━━━━━━━━┓
-┃ user     ┃ memTotal ┃

-toc_title: Combinadores
----
-
-# Combinadores de funciones agregadas {#aggregate_functions_combinators}
-
-El nombre de una función agregada puede tener un sufijo anexado. Esto cambia la forma en que funciona la función de agregado.
-
-## -Si {#agg-functions-combinator-if}
-
-The suffix -If can be appended to the name of any aggregate function. In this case, the aggregate function accepts an extra argument – a condition (Uint8 type). The aggregate function processes only the rows that trigger the condition. If the condition was not triggered even once, it returns a default value (usually zeros or empty strings).
-
-Ejemplos: `sumIf(column, cond)`, `countIf(cond)`, `avgIf(x, cond)`, `quantilesTimingIf(level1, level2)(x, cond)`, `argMinIf(arg, val, cond)` y así sucesivamente.
-
-Con las funciones de agregado condicional, puede calcular agregados para varias condiciones a la vez, sin utilizar subconsultas y `JOIN`Por ejemplo, en Yandex.Metrica, las funciones de agregado condicional se utilizan para implementar la funcionalidad de comparación de segmentos.
-
-## -Matriz {#agg-functions-combinator-array}
-
-El sufijo -Array se puede agregar a cualquier función agregada. En este caso, la función de agregado toma argumentos del ‘Array(T)’ tipo (arrays) en lugar de ‘T’ argumentos de tipo. Si la función de agregado acepta varios argumentos, deben ser matrices de igual longitud. Al procesar matrices, la función de agregado funciona como la función de agregado original en todos los elementos de la matriz.
-
-Ejemplo 1: `sumArray(arr)` - Totales de todos los elementos de todos ‘arr’ matriz. En este ejemplo, podría haber sido escrito más simplemente: `sum(arraySum(arr))`.
-
-Ejemplo 2: `uniqArray(arr)` – Counts the number of unique elements in all ‘arr’ matriz. Esto podría hacerse de una manera más fácil: `uniq(arrayJoin(arr))`, pero no siempre es posible agregar ‘arrayJoin’ a una consulta.
-
--If y -Array se pueden combinar. Obstante, ‘Array’ debe venir primero, entonces ‘If’. Ejemplos: `uniqArrayIf(arr, cond)`, `quantilesTimingArrayIf(level1, level2)(arr, cond)`. Debido a este pedido, el ‘cond’ argumento no será una matriz.
-
-## -Estado {#agg-functions-combinator-state}
-
-Si aplica este combinador, la función de agregado no devuelve el valor resultante (como el número de valores únicos para el [uniq](reference.md#agg_function-uniq) función), pero un estado intermedio de la agregación (para `uniq`, esta es la tabla hash para calcular el número de valores únicos). Este es un `AggregateFunction(...)` que puede ser utilizado para su posterior procesamiento o almacenado en una tabla para terminar de agregar más tarde.
-
-Para trabajar con estos estados, use:
-
--   [AgregaciónMergeTree](../../engines/table-engines/mergetree-family/aggregatingmergetree.md) motor de mesa.
--   [finalizeAggregation](../../sql-reference/functions/other-functions.md#function-finalizeaggregation) función.
--   [runningAccumulate](../../sql-reference/functions/other-functions.md#function-runningaccumulate) función.
--   [-Fusionar](#aggregate_functions_combinators-merge) combinador.
--   [-MergeState](#aggregate_functions_combinators-mergestate) combinador.
-
-## -Fusionar {#aggregate_functions_combinators-merge}
-
-Si aplica este combinador, la función de agregado toma el estado de agregación intermedio como argumento, combina los estados para finalizar la agregación y devuelve el valor resultante.
-
-## -MergeState {#aggregate_functions_combinators-mergestate}
-
-Combina los estados de agregación intermedios de la misma manera que el combinador -Merge. Sin embargo, no devuelve el valor resultante, sino un estado de agregación intermedio, similar al combinador -State.
-
-## -ForEach {#agg-functions-combinator-foreach}
-
-Convierte una función de agregado para tablas en una función de agregado para matrices que agrega los elementos de matriz correspondientes y devuelve una matriz de resultados. Por ejemplo, `sumForEach` para las matrices `[1, 2]`, `[3, 4, 5]`y`[6, 7]`devuelve el resultado `[10, 13, 5]` después de agregar los elementos de la matriz correspondientes.
-
-## -OPor defecto {#agg-functions-combinator-ordefault}
-
-Cambia el comportamiento de una función agregada.
-
-Si una función agregada no tiene valores de entrada, con este combinador devuelve el valor predeterminado para su tipo de datos de retorno. Se aplica a las funciones agregadas que pueden tomar datos de entrada vacíos.
-
-`-OrDefault` se puede utilizar con otros combinadores.
-
-**Sintaxis**
-
-``` sql
-<aggFunction>OrDefault(x)
-```
-
-**Parámetros**
-
--   `x` — Aggregate function parameters.
-
-**Valores devueltos**
-
-Devuelve el valor predeterminado del tipo devuelto de una función de agregado si no hay nada que agregar.
-
-El tipo depende de la función de agregado utilizada.
-
-**Ejemplo**
-
-Consulta:
-
-``` sql
-SELECT avg(number), avgOrDefault(number) FROM numbers(0)
-```
-
-Resultado:
-
-``` text
-┌─avg(number)─┬─avgOrDefault(number)─┐
-│         nan │                    0 │
-└─────────────┴──────────────────────┘
-```
-
-También `-OrDefault` se puede utilizar con otros combinadores. Es útil cuando la función de agregado no acepta la entrada vacía.
-
-Consulta:
-
-``` sql
-SELECT avgOrDefaultIf(x, x > 10)
-FROM
-(
-    SELECT toDecimal32(1.23, 2) AS x
-)
-```
-
-Resultado:
-

-
-## -OrNull {#agg-functions-combinator-ornull}
-
-Cambia el comportamiento de una función agregada.
-
-Este combinador convierte un resultado de una función agregada en [NULL](../data-types/nullable.md) tipo de datos. Si la función de agregado no tiene valores para calcular devuelve [NULL](../syntax.md#null-literal).
-
-`-OrNull` se puede utilizar con otros combinadores.
-
-**Sintaxis**
-
-``` sql
-<aggFunction>OrNull(x)
-```
-
-**Parámetros**
-
--   `x` — Aggregate function parameters.
-
-**Valores devueltos**
-
--   El resultado de la función de agregado, convertida a la `Nullable` tipo de datos.
--   `NULL`, si no hay nada que agregar.
-
-Tipo: `Nullable(aggregate function return type)`.
-
-**Ejemplo**
-
-Añadir `-orNull` hasta el final de la función agregada.
-
-Consulta:
-
-``` sql
-SELECT sumOrNull(number), toTypeName(sumOrNull(number)) FROM numbers(10) WHERE number > 10
-```
-
-Resultado:

-## -Remuestrear {#agg-functions-combinator-resample}
-
-Permite dividir los datos en grupos y, a continuación, agregar por separado los datos de esos grupos. Los grupos se crean dividiendo los valores de una columna en intervalos.
-
-``` sql
-<aggFunction>Resample(start, end, step)(<aggFunction_params>, resampling_key)
-```
-
-**Parámetros**
-
--   `start` — Starting value of the whole required interval for `resampling_key` valor.
--   `stop` — Ending value of the whole required interval for `resampling_key` valor. Todo el intervalo no incluye el `stop` valor `[start, stop)`.
--   `step` — Step for separating the whole interval into subintervals. The `aggFunction` se ejecuta sobre cada uno de esos subintervalos de forma independiente.
--   `resampling_key` — Column whose values are used for separating data into intervals.
--   `aggFunction_params` — `aggFunction` parámetros.
-
-**Valores devueltos**
-
--   Matriz de `aggFunction` resultados para cada subintervalo.

-│ David  │  62 │  9.9 │
-│ Brian  │  60 │   16 │
-└────────┴─────┴──────┘
-```
-
-Obtengamos los nombres de las personas cuya edad se encuentra en los intervalos de `[30,60)` y `[60,75)`. Como usamos la representación entera para la edad, obtenemos edades en el `[30, 59]` y `[60,74]` intervalo.
-
-Para agregar nombres en una matriz, usamos el [Método de codificación de datos:](reference.md#agg_function-grouparray) función de agregado. Se necesita un argumento. En nuestro caso, es el `name` columna. El `groupArrayResample` función debe utilizar el `age` columna para agregar nombres por edad. Para definir los intervalos requeridos, pasamos el `30, 75, 30` discusiones sobre el `groupArrayResample` función.
-
-``` sql
-SELECT groupArrayResample(30, 75, 30)(name, age) FROM people
-```
-
-``` text
-┌─groupArrayResample(30, 75, 30)(name, age)─────┐
-│ [['Alice','Mary','Evelyn'],['David','Brian']] │
-└───────────────────────────────────────────────┘
-```
-
-Considera los resultados.
-
-`Jonh` est? fuera de la muestra porque es demasiado joven. Otras personas se distribuyen de acuerdo con los intervalos de edad especificados.
-
-Ahora vamos a contar el número total de personas y su salario promedio en los intervalos de edad especificados.
-
-``` sql

-# Funciones agregadas {#aggregate-functions}
-
-Las funciones agregadas funcionan en el [normal](http://www.sql-tutorial.com/sql-aggregate-functions-sql-tutorial) forma esperada por los expertos en bases de datos.
-
-ClickHouse también es compatible:
-
--   [Funciones agregadas paramétricas](parametric-functions.md#aggregate_functions_parametric) que aceptan otros parámetros además de las columnas.
--   [Combinadores](combinators.md#aggregate_functions_combinators), que cambian el comportamiento de las funciones agregadas.
-
-## Procesamiento NULL {#null-processing}
-
-Durante la agregación, todos `NULL`s se omiten.
-
-**Ejemplos:**
-
-Considere esta tabla:
-
-``` text
-┌─x─┬────y─┐
-│ 1 │    2 │
-│ 2 │ ᴺᵁᴸᴸ │
-│ 3 │    2 │
-│ 3 │    3 │
-│ 3 │ ᴺᵁᴸᴸ │
-└───┴──────┘
-```
-
-Digamos que necesita sumar los valores en el `y` columna:
-
-``` sql
-SELECT sum(y) FROM t_null_big
-```
-
-    ┌─sum(y)─┐
-    │      7 │
-    └────────┘
-
-El `sum` función interpreta `NULL` como `0`. En particular, esto significa que si la función recibe la entrada de una selección donde todos los valores son `NULL`, entonces el resultado será `0`, ni `NULL`.
-
-Ahora puedes usar el `groupArray` función para crear una matriz a partir de la `y` columna:
-
-``` sql
-SELECT groupArray(y) FROM t_null_big
-```
-
-``` text
-┌─groupArray(y)─┐
-│ [2,2,3]       │
-└───────────────┘
-```
-
-`groupArray` no incluye `NULL` en la matriz resultante.

-# Funciones agregadas paramétricas {#aggregate_functions_parametric}
-
-Some aggregate functions can accept not only argument columns (used for compression), but a set of parameters – constants for initialization. The syntax is two pairs of brackets instead of one. The first is for parameters, and the second is for arguments.
-
-## histograma {#histogram}
-
-Calcula un histograma adaptativo. No garantiza resultados precisos.
-
-``` sql
-histogram(number_of_bins)(values)
-```
-
-Las funciones utiliza [Un algoritmo de árbol de decisión paralelo de transmisión](http://jmlr.org/papers/volume11/ben-haim10a/ben-haim10a.pdf). Los bordes de los contenedores de histograma se ajustan a medida que los nuevos datos entran en una función. En caso común, los anchos de los contenedores no son iguales.
-
-**Parámetros**
-
-`number_of_bins` — Upper limit for the number of bins in the histogram. The function automatically calculates the number of bins. It tries to reach the specified number of bins, but if it fails, it uses fewer bins.
-`values` — [Expresion](../syntax.md#syntax-expressions) resultando en valores de entrada.
-
-**Valores devueltos**
-
--   [Matriz](../../sql-reference/data-types/array.md) de [Tuples](../../sql-reference/data-types/tuple.md) del siguiente formato:
-
-        ```
-        [(lower_1, upper_1, height_1), ... (lower_N, upper_N, height_N)]
-        ```
-
-        - `lower` — Lower bound of the bin.
-        - `upper` — Upper bound of the bin.
-        - `height` — Calculated height of the bin.
-
-**Ejemplo**
-
-``` sql
-SELECT histogram(5)(number + 1)
-FROM (
-    SELECT *
-    FROM system.numbers
-    LIMIT 20
-)
-```
-
-``` text
-┌─histogram(5)(plus(number, 1))───────────────────────────────────────────┐

-└─────────────────────────────────────────────────────────────────────────┘
-```
-
-Puede visualizar un histograma con el [Bar](../../sql-reference/functions/other-functions.md#function-bar) función, por ejemplo:
-
-``` sql
-WITH histogram(5)(rand() % 100) AS hist
-SELECT
-    arrayJoin(hist).3 AS height,
-    bar(height, 0, 6, 5) AS bar
-FROM
-(
-    SELECT *
-    FROM system.numbers
-    LIMIT 20

-## sequenceMatch(pattern)(timestamp, cond1, cond2, …) {#function-sequencematch}
-
-Comprueba si la secuencia contiene una cadena de eventos que coincida con el patrón.
-
-``` sql
-sequenceMatch(pattern)(timestamp, cond1, cond2, ...)
-```
-
-!!! warning "Advertencia"
-    Los eventos que ocurren en el mismo segundo pueden estar en la secuencia en un orden indefinido que afecta el resultado.
-
-**Parámetros**
-
--   `pattern` — Pattern string. See [Sintaxis de patrón](#sequence-function-pattern-syntax).
-
--   `timestamp` — Column considered to contain time data. Typical data types are `Date` y `DateTime`. También puede utilizar cualquiera de los [UInt](../../sql-reference/data-types/int-uint.md) tipos de datos.
-
--   `cond1`, `cond2` — Conditions that describe the chain of events. Data type: `UInt8`. Puede pasar hasta 32 argumentos de condición. La función sólo tiene en cuenta los eventos descritos en estas condiciones. Si la secuencia contiene datos que no se describen en una condición, la función los omite.
-
-**Valores devueltos**
-
--   1, si el patrón coincide.

-
-<a name="sequence-function-pattern-syntax"></a>
-**Sintaxis de patrón**
-
--   `(?N)` — Matches the condition argument at position `N`. Las condiciones están numeradas en el `[1, 32]` gama. Por ejemplo, `(?1)` coincide con el argumento pasado al `cond1` parámetro.
-
--   `.*` — Matches any number of events. You don't need conditional arguments to match this element of the pattern.
-
--   `(?t operator value)` — Sets the time in seconds that should separate two events. For example, pattern `(?1)(?t>1800)(?2)` coincide con los eventos que ocurren a más de 1800 segundos el uno del otro. Un número arbitrario de cualquier evento puede estar entre estos eventos. Puede usar el `>=`, `>`, `<`, `<=` operador.
-
-**Ejemplos**
-
-Considere los datos en el `t` tabla:

-└───────────────────────────────────────────────────────────────────────┘
-```
-
-La función encontró la cadena de eventos donde el número 2 sigue al número 1. Se saltó el número 3 entre ellos, porque el número no se describe como un evento. Si queremos tener en cuenta este número al buscar la cadena de eventos dada en el ejemplo, debemos establecer una condición para ello.
-

-
-En este caso, la función no pudo encontrar la cadena de eventos que coincida con el patrón, porque el evento para el número 3 ocurrió entre 1 y 2. Si en el mismo caso comprobamos la condición para el número 4, la secuencia coincidiría con el patrón.

-## ventanaEmbudo {#windowfunnel}
-
-Busca cadenas de eventos en una ventana de tiempo deslizante y calcula el número máximo de eventos que ocurrieron desde la cadena.
-
-La función funciona de acuerdo con el algoritmo:
-
--   La función busca datos que desencadenan la primera condición en la cadena y establece el contador de eventos en 1. Este es el momento en que comienza la ventana deslizante.
-
--   Si los eventos de la cadena ocurren secuencialmente dentro de la ventana, el contador se incrementa. Si se interrumpe la secuencia de eventos, el contador no se incrementa.
-
--   Si los datos tienen varias cadenas de eventos en diferentes puntos de finalización, la función solo generará el tamaño de la cadena más larga.
-
-**Sintaxis**
-
-``` sql
-windowFunnel(window, [mode])(timestamp, cond1, cond2, ..., condN)
-```
-
-**Parámetros**
-
--   `window` — Length of the sliding window in seconds.
--   `mode` - Es un argumento opcional.
-    -   `'strict'` - Cuando el `'strict'` se establece, windowFunnel() aplica condiciones solo para los valores únicos.
--   `timestamp` — Name of the column containing the timestamp. Data types supported: [Fecha](../../sql-reference/data-types/date.md), [FechaHora](../../sql-reference/data-types/datetime.md#data_type-datetime) y otros tipos de enteros sin signo (tenga en cuenta que aunque timestamp admite el `UInt64` tipo, su valor no puede exceder el máximo de Int64, que es 2 ^ 63 - 1).
--   `cond` — Conditions or data describing the chain of events. [UInt8](../../sql-reference/data-types/int-uint.md).
-

-
-## UniqUpTo(N)(x) {#uniquptonx}
-
-Calculates the number of different argument values ​​if it is less than or equal to N. If the number of different argument values is greater than N, it returns N + 1.
-
-Recomendado para usar con Ns pequeños, hasta 10. El valor máximo de N es 100.
-
-Para el estado de una función agregada, utiliza la cantidad de memoria igual a 1 + N \* el tamaño de un valor de bytes.
-Para las cadenas, almacena un hash no criptográfico de 8 bytes. Es decir, el cálculo se aproxima a las cadenas.
-
-La función también funciona para varios argumentos.
-
-Funciona lo más rápido posible, excepto en los casos en que se usa un valor N grande y el número de valores únicos es ligeramente menor que N.
-
-Ejemplo de uso:
-
-``` text
-Problem: Generate a report that shows only keywords that produced at least 5 unique users.
-Solution: Write in the GROUP BY query SearchPhrase HAVING uniqUpTo(4)(UserID) >= 5

-# Referencia de función agregada {#aggregate-functions-reference}
-
-## contar {#agg_function-count}
-
-Cuenta el número de filas o valores no NULL.
-
-ClickHouse admite las siguientes sintaxis para `count`:
-- `count(expr)` o `COUNT(DISTINCT expr)`.
-- `count()` o `COUNT(*)`. El `count()` la sintaxis es específica de ClickHouse.
-
-**Parámetros**
-
-La función puede tomar:
-
--   Cero parámetros.
--   Una [expresion](../syntax.md#syntax-expressions).
-
-**Valor devuelto**
-
--   Si se llama a la función sin parámetros, cuenta el número de filas.
--   Si el [expresion](../syntax.md#syntax-expressions) se pasa, entonces la función cuenta cuántas veces esta expresión devuelve no nula. Si la expresión devuelve un [NULL](../../sql-reference/data-types/nullable.md)-type valor, entonces el resultado de `count` no se queda `Nullable`. La función devuelve 0 si la expresión devuelta `NULL` para todas las filas.
-
-En ambos casos el tipo del valor devuelto es [UInt64](../../sql-reference/data-types/int-uint.md).
-
-**Detalles**
-
-ClickHouse soporta el `COUNT(DISTINCT ...)` sintaxis. El comportamiento de esta construcción depende del [count_distinct_implementation](../../operations/settings/settings.md#settings-count_distinct_implementation) configuración. Define cuál de las [uniq\*](#agg_function-uniq) se utiliza para realizar la operación. El valor predeterminado es el [uniqExact](#agg_function-uniqexact) función.
-
-El `SELECT count() FROM table` consulta no está optimizado, porque el número de entradas en la tabla no se almacena por separado. Elige una pequeña columna de la tabla y cuenta el número de valores en ella.
-
-**Ejemplos**
-
-Ejemplo 1:
-
-``` sql
-SELECT count() FROM t
-```
-
-``` text
-┌─count()─┐
-│       5 │
-└─────────┘
-```
-
-Ejemplo 2:
-
-``` sql
-SELECT name, value FROM system.settings WHERE name = 'count_distinct_implementation'
-```
-
-``` text
-┌─name──────────────────────────┬─value─────┐
-│ count_distinct_implementation │ uniqExact │
-└───────────────────────────────┴───────────┘
-```
-
-``` sql
-SELECT count(DISTINCT num) FROM t
-```
-
-``` text
-┌─uniqExact(num)─┐
-│              3 │
-└────────────────┘
-```
-
-Este ejemplo muestra que `count(DISTINCT num)` se realiza por el `uniqExact` función según el `count_distinct_implementation` valor de ajuste.
-
-## cualquiera (x) {#agg_function-any}
-
-Selecciona el primer valor encontrado.
-La consulta se puede ejecutar en cualquier orden e incluso en un orden diferente cada vez, por lo que el resultado de esta función es indeterminado.
-Para obtener un resultado determinado, puede usar el ‘min’ o ‘max’ función en lugar de ‘any’.
-
-En algunos casos, puede confiar en el orden de ejecución. Esto se aplica a los casos en que SELECT proviene de una subconsulta que usa ORDER BY.
-
-Cuando un `SELECT` consulta tiene el `GROUP BY` cláusula o al menos una función agregada, ClickHouse (en contraste con MySQL) requiere que todas las expresiones `SELECT`, `HAVING`, y `ORDER BY` las cláusulas pueden calcularse a partir de claves o de funciones agregadas. En otras palabras, cada columna seleccionada de la tabla debe usarse en claves o dentro de funciones agregadas. Para obtener un comportamiento como en MySQL, puede colocar las otras columnas en el `any` función de agregado.
-
-## Cualquier pesado (x) {#anyheavyx}
-
-Selecciona un valor que ocurre con frecuencia [pesos pesados](http://www.cs.umd.edu/~samir/498/karp.pdf) algoritmo. Si hay un valor que se produce más de la mitad de los casos en cada uno de los subprocesos de ejecución de la consulta, se devuelve este valor. Normalmente, el resultado es no determinista.
-
-``` sql
-anyHeavy(column)
-```
-
-**Argumento**
-
--   `column` – The column name.
-
-**Ejemplo**
-
-Tome el [A tiempo](../../getting-started/example-datasets/ontime.md) conjunto de datos y seleccione cualquier valor que ocurra con frecuencia `AirlineID` columna.
-
-``` sql
-SELECT anyHeavy(AirlineID) AS res
-FROM ontime
-```
-
-``` text
-┌───res─┐
-│ 19690 │
-└───────┘
-```
-
-## Cualquier último (x) {#anylastx}
-
-Selecciona el último valor encontrado.
-El resultado es tan indeterminado como para el `any` función.

-La función toma un número variable de parámetros. Los parámetros pueden ser `Tuple`, `Array`, `Date`, `DateTime`, `String`, o tipos numéricos.
-
-`HLL_precision` es el logaritmo base-2 del número de células en [HyperLogLog](https://en.wikipedia.org/wiki/HyperLogLog). Opcional, puede utilizar la función como `uniqCombined(x[, ...])`. El valor predeterminado para `HLL_precision` es 17, que es efectivamente 96 KiB de espacio (2 ^ 17 celdas, 6 bits cada una).
-
-**Valor devuelto**
-
--   Numero [UInt64](../../sql-reference/data-types/int-uint.md)-tipo número.
-
-**Detalles de implementación**
-
-Función:
-
--   Calcula un hash (hash de 64 bits para `String` y 32 bits de lo contrario) para todos los parámetros en el agregado, luego lo usa en los cálculos.
-
--   Utiliza una combinación de tres algoritmos: matriz, tabla hash e HyperLogLog con una tabla de corrección de errores.
-
-        For a small number of distinct elements, an array is used. When the set size is larger, a hash table is used. For a larger number of elements, HyperLogLog is used, which will occupy a fixed amount of memory.
-
--   Proporciona el resultado de forma determinista (no depende del orden de procesamiento de la consulta).
-
-!!! note "Nota"
-    Dado que usa hash de 32 bits para no-`String` tipo, el resultado tendrá un error muy alto para cardinalidades significativamente mayores que `UINT_MAX` (el error aumentará rápidamente después de unas pocas decenas de miles de millones de valores distintos), por lo tanto, en este caso debe usar [UniqCombined64](#agg_function-uniqcombined64)
-
-En comparación con el [uniq](#agg_function-uniq) función, el `uniqCombined`:
-
--   Consume varias veces menos memoria.
--   Calcula con una precisión varias veces mayor.
--   Por lo general, tiene un rendimiento ligeramente menor. En algunos escenarios, `uniqCombined` puede funcionar mejor que `uniq`, por ejemplo, con consultas distribuidas que transmiten un gran número de estados de agregación a través de la red.

-
-**Detalles de implementación**
-
-Función:
-
--   Calcula un hash para todos los parámetros en el agregado, luego lo usa en los cálculos.
-
--   Utiliza el algoritmo HyperLogLog para aproximar el número de valores de argumento diferentes.
-
-        212 5-bit cells are used. The size of the state is slightly more than 2.5 KB. The result is not very accurate (up to ~10% error) for small data sets (<10K elements). However, the result is fairly accurate for high-cardinality data sets (10K-100M), with a maximum error of ~1.6%. Starting from 100M, the estimation error increases, and the function will return very inaccurate results for data sets with extremely high cardinality (1B+ elements).
-
--   Proporciona el resultado determinado (no depende del orden de procesamiento de la consulta).
-
-No recomendamos usar esta función. En la mayoría de los casos, use el [uniq](#agg_function-uniq) o [uniqCombined](#agg_function-uniqcombined) función.

-## uniqExact {#agg_function-uniqexact}
-
-Calcula el número exacto de diferentes valores de argumento.

-```
-
-Utilice el `uniqExact` función si necesita absolutamente un resultado exacto. De lo contrario, use el [uniq](#agg_function-uniq) función.
-
-El `uniqExact` función utiliza más memoria que `uniq`, porque el tamaño del estado tiene un crecimiento ilimitado a medida que aumenta el número de valores diferentes.

-## ¿Cómo puedo hacerlo?) {#agg_function-grouparray}
-
-Crea una matriz de valores de argumento.
-Los valores se pueden agregar a la matriz en cualquier orden (indeterminado).
-
-La segunda versión (con el `max_size` parámetro) limita el tamaño de la matriz resultante a `max_size` elemento.
-Por ejemplo, `groupArray (1) (x)` es equivalente a `[any (x)]`.
-
-En algunos casos, aún puede confiar en el orden de ejecución. Esto se aplica a los casos en que `SELECT` procede de una subconsulta que utiliza `ORDER BY`.
-
-## GrupoArrayInsertAt {#grouparrayinsertat}
-
-Inserta un valor en la matriz en la posición especificada.
-
-**Sintaxis**
-
-``` sql
-groupArrayInsertAt(default_x, size)(x, pos);
-```
-
-Si en una consulta se insertan varios valores en la misma posición, la función se comporta de las siguientes maneras:
-
--   Si se ejecuta una consulta en un solo subproceso, se utiliza el primero de los valores insertados.
--   Si una consulta se ejecuta en varios subprocesos, el valor resultante es uno indeterminado de los valores insertados.
-
-**Parámetros**
-
--   `x` — Value to be inserted. [Expresion](../syntax.md#syntax-expressions) lo que resulta en uno de los [tipos de datos compatibles](../../sql-reference/data-types/index.md).
--   `pos` — Position at which the specified element `x` se va a insertar. La numeración de índices en la matriz comienza desde cero. [UInt32](../../sql-reference/data-types/int-uint.md#uint-ranges).
--   `default_x`— Default value for substituting in empty positions. Optional parameter. [Expresion](../syntax.md#syntax-expressions) dando como resultado el tipo de datos configurado para `x` parámetro. Si `default_x` no está definido, el [valores predeterminados](../../sql-reference/statements/create.md#create-default-values) se utilizan.
--   `size`— Length of the resulting array. Optional parameter. When using this parameter, the default value `default_x` debe ser especificado. [UInt32](../../sql-reference/data-types/int-uint.md#uint-ranges).
-
-**Valor devuelto**

-## stochasticLinearRegression {#agg_functions-stochasticlinearregression}
-
-Esta función implementa la regresión lineal estocástica. Admite parámetros personalizados para la tasa de aprendizaje, el coeficiente de regularización L2, el tamaño de mini lote y tiene pocos métodos para actualizar los pesos ([Adán](https://en.wikipedia.org/wiki/Stochastic_gradient_descent#Adam) (utilizado por defecto), [SGD simple](https://en.wikipedia.org/wiki/Stochastic_gradient_descent), [Impulso](https://en.wikipedia.org/wiki/Stochastic_gradient_descent#Momentum), [Nesterov](https://mipt.ru/upload/medialibrary/d7e/41-91.pdf)).
-
-### Parámetros {#agg_functions-stochasticlinearregression-parameters}
-
-Hay 4 parámetros personalizables. Se pasan a la función secuencialmente, pero no es necesario pasar los cuatro; se usarán valores predeterminados, sin embargo, un buen modelo requirió algún ajuste de parámetros.
-
-``` text
-stochasticLinearRegression(1.0, 1.0, 10, 'SGD')
-```
-
-1.  `learning rate` es el coeficiente en la longitud del paso, cuando se realiza el paso de descenso de gradiente. Una tasa de aprendizaje demasiado grande puede causar pesos infinitos del modelo. El valor predeterminado es `0.00001`.
-2.  `l2 regularization coefficient` que puede ayudar a prevenir el sobreajuste. El valor predeterminado es `0.1`.
-3.  `mini-batch size` establece el número de elementos, cuyos gradientes se calcularán y sumarán para realizar un paso de descenso de gradiente. El descenso estocástico puro usa un elemento, sin embargo, tener lotes pequeños (aproximadamente 10 elementos) hace que los pasos de gradiente sean más estables. El valor predeterminado es `15`.
-4.  `method for updating weights`, son: `Adam` (predeterminada), `SGD`, `Momentum`, `Nesterov`. `Momentum` y `Nesterov` requieren un poco más de cálculos y memoria, sin embargo, resultan útiles en términos de velocidad de convergencia y estabilidad de los métodos de gradiente estocásticos.
-
-### Uso {#agg_functions-stochasticlinearregression-usage}
-
-`stochasticLinearRegression` se utiliza en dos pasos: ajustar el modelo y predecir nuevos datos. Para ajustar el modelo y guardar su estado para su uso posterior, utilizamos `-State` combinador, que básicamente guarda el estado (pesos del modelo, etc.).
-Para predecir usamos la función [evalMLMethod](../functions/machine-learning-functions.md#machine_learning_methods-evalmlmethod), que toma un estado como argumento, así como características para predecir.
-
-<a name="stochasticlinearregression-usage-fitting"></a>
-
-**1.** Accesorio
-
-Dicha consulta puede ser utilizada.
-
-``` sql
-CREATE TABLE IF NOT EXISTS train_data
-(
-    param1 Float64,
-    param2 Float64,
-    target Float64
-) ENGINE = Memory;
-
-CREATE TABLE your_model ENGINE = Memory AS SELECT
-stochasticLinearRegressionState(0.1, 0.0, 5, 'SGD')(target, param1, param2)
-AS state FROM train_data;
-```
-
-Aquí también tenemos que insertar datos en `train_data` tabla. El número de parámetros no es fijo, depende solo del número de argumentos, pasados a `linearRegressionState`. Todos deben ser valores numéricos.
-Tenga en cuenta que la columna con valor objetivo (que nos gustaría aprender a predecir) se inserta como primer argumento.
-
-**2.** Predecir
-
-Después de guardar un estado en la tabla, podemos usarlo varias veces para la predicción, o incluso fusionarlo con otros estados y crear nuevos modelos aún mejores.
-
-``` sql
-WITH (SELECT state FROM your_model) AS model SELECT
-evalMLMethod(model, param1, param2) FROM test_data
-```
-
-La consulta devolverá una columna de valores predichos. Tenga en cuenta que el primer argumento de `evalMLMethod` ser `AggregateFunctionState` objeto, siguiente son columnas de características.
-
-`test_data` es una mesa como `train_data` pero puede no contener el valor objetivo.
-
-### Nota {#agg_functions-stochasticlinearregression-notes}
-
-1.  Para fusionar dos modelos, el usuario puede crear dicha consulta:
-    `sql  SELECT state1 + state2 FROM your_models`
-    donde `your_models` la tabla contiene ambos modelos. Esta consulta devolverá un nuevo `AggregateFunctionState` objeto.
-
-2.  El usuario puede obtener pesos del modelo creado para sus propios fines sin guardar el modelo si no `-State` combinador se utiliza.
-    `sql  SELECT stochasticLinearRegression(0.01)(target, param1, param2) FROM train_data`
-    Dicha consulta se ajustará al modelo y devolverá sus pesos: primero son los pesos, que corresponden a los parámetros del modelo, el último es el sesgo. Entonces, en el ejemplo anterior, la consulta devolverá una columna con 3 valores.

-## stochasticLogisticRegression {#agg_functions-stochasticlogisticregression}
-
-Esta función implementa la regresión logística estocástica. Se puede usar para problemas de clasificación binaria, admite los mismos parámetros personalizados que stochasticLinearRegression y funciona de la misma manera.
-
-### Parámetros {#agg_functions-stochasticlogisticregression-parameters}
-
-Los parámetros son exactamente los mismos que en stochasticLinearRegression:
-`learning rate`, `l2 regularization coefficient`, `mini-batch size`, `method for updating weights`.
-Para obtener más información, consulte [parámetros](#agg_functions-stochasticlinearregression-parameters).

-``` text
-stochasticLogisticRegression(1.0, 1.0, 10, 'SGD')
-```
-
-1.  Accesorio
-
-<!-- -->
-
-    See the `Fitting` section in the [stochasticLinearRegression](#stochasticlinearregression-usage-fitting) description.
-
-    Predicted labels have to be in \[-1, 1\].
-
-1.  Predecir
-
-<!-- -->
-
-    Using saved state we can predict probability of object having label `1`.
-
-    ``` sql
-    WITH (SELECT state FROM your_model) AS model SELECT
-    evalMLMethod(model, param1, param2) FROM test_data
-    ```
-
-    The query will return a column of probabilities. Note that first argument of `evalMLMethod` is `AggregateFunctionState` object, next are columns of features.
-
-    We can also set a bound of probability, which assigns elements to different labels.
-
-    ``` sql
-    SELECT ans < 1.1 AND ans > 0.5 FROM
-    (WITH (SELECT state FROM your_model) AS model SELECT
-    evalMLMethod(model, param1, param2) AS ans FROM test_data)
-    ```
-
-    Then the result will be labels.
-
-    `test_data` is a table like `train_data` but may not contain target value.

-# AggregateFunction(name, types_of_arguments…) {#data-type-aggregatefunction}
-
-Aggregate functions can have an implementation-defined intermediate state that can be serialized to an AggregateFunction(…) data type and stored in a table, usually, by means of [una vista materializada](../../sql-reference/statements/create.md#create-view). La forma común de producir un estado de función agregada es llamando a la función agregada con el `-State` sufijo. Para obtener el resultado final de la agregación en el futuro, debe utilizar la misma función de agregado con el `-Merge`sufijo.
-
-`AggregateFunction` — parametric data type.
-
-**Parámetros**
-
--   Nombre de la función de agregado.
-
-        If the function is parametric, specify its parameters too.
-
--   Tipos de los argumentos de la función agregada.
-
-**Ejemplo**
-
-``` sql
-CREATE TABLE t
-(
-    column1 AggregateFunction(uniq, UInt64),
-    column2 AggregateFunction(anyIf, String, UInt8),
-    column3 AggregateFunction(quantiles(0.5, 0.9), UInt64)
-) ENGINE = ...
-```
-
-[uniq](../../sql-reference/aggregate-functions/reference.md#agg_function-uniq), anyIf ([cualquier](../../sql-reference/aggregate-functions/reference.md#agg_function-any)+[Si](../../sql-reference/aggregate-functions/combinators.md#agg-functions-combinator-if)) y [cantiles](../../sql-reference/aggregate-functions/reference.md) son las funciones agregadas admitidas en ClickHouse.
-
-## Uso {#usage}
-
-### Inserción de datos {#data-insertion}
-
-Para insertar datos, utilice `INSERT SELECT` con agregado `-State`- función.
-
-**Ejemplos de funciones**
-
-``` sql
-uniqState(UserID)
-quantilesState(0.5, 0.9)(SendTiming)
-```
-
-En contraste con las funciones correspondientes `uniq` y `quantiles`, `-State`- funciones devuelven el estado, en lugar del valor final. En otras palabras, devuelven un valor de `AggregateFunction` tipo.
-
-En los resultados de `SELECT` consulta, los valores de `AggregateFunction` tipo tiene representación binaria específica de la implementación para todos los formatos de salida de ClickHouse. Si volcar datos en, por ejemplo, `TabSeparated` formato con `SELECT` consulta, entonces este volcado se puede cargar de nuevo usando `INSERT` consulta.
-
-### Selección de datos {#data-selection}
-
-Al seleccionar datos de `AggregatingMergeTree` mesa, uso `GROUP BY` cláusula y las mismas funciones agregadas que al insertar datos, pero usando `-Merge`sufijo.
-
-Una función agregada con `-Merge` sufijo toma un conjunto de estados, los combina y devuelve el resultado de la agregación de datos completa.
-
-Por ejemplo, las siguientes dos consultas devuelven el mismo resultado:
-
-``` sql
-SELECT uniq(UserID) FROM table
-
-SELECT uniqMerge(state) FROM (SELECT uniqState(UserID) AS state FROM table GROUP BY RegionID)
-```
-
-## Ejemplo de uso {#usage-example}

-Ver [AgregaciónMergeTree](../../engines/table-engines/mergetree-family/aggregatingmergetree.md) Descripción del motor.

-
-# Matriz (t) {#data-type-array}
-
-Una matriz de `T`-tipo de artículos. `T` puede ser cualquier tipo de datos, incluida una matriz.
-
-## Creación de una matriz {#creating-an-array}
-
-Puede usar una función para crear una matriz:
-
-``` sql
-array(T)
-```
-
-También puede usar corchetes.
-
-``` sql
-[]
-```
-
-Ejemplo de creación de una matriz:
-
-``` sql
-SELECT array(1, 2) AS x, toTypeName(x)
-```
-
-``` text
-┌─x─────┬─toTypeName(array(1, 2))─┐
-│ [1,2] │ Array(UInt8)            │
-└───────┴─────────────────────────┘
-```
-
-``` sql
-SELECT [1, 2] AS x, toTypeName(x)
-```
-
-``` text
-┌─x─────┬─toTypeName([1, 2])─┐
-│ [1,2] │ Array(UInt8)       │
-└───────┴────────────────────┘
-```
-
-## Trabajar con tipos de datos {#working-with-data-types}
-
-Al crear una matriz sobre la marcha, ClickHouse define automáticamente el tipo de argumento como el tipo de datos más estrecho que puede almacenar todos los argumentos enumerados. Si hay alguna [NULL](nullable.md#data_type-nullable) o literal [NULL](../../sql-reference/syntax.md#null-literal) valores, el tipo de un elemento de matriz también se convierte en [NULL](nullable.md).
-
-Si ClickHouse no pudo determinar el tipo de datos, genera una excepción. Por ejemplo, esto sucede cuando se intenta crear una matriz con cadenas y números simultáneamente (`SELECT array(1, 'a')`).
-
-Ejemplos de detección automática de tipos de datos:
-
-``` sql
-SELECT array(1, 2, NULL) AS x, toTypeName(x)
-```
-
-``` text
-┌─x──────────┬─toTypeName(array(1, 2, NULL))─┐
-│ [1,2,NULL] │ Array(Nullable(UInt8))        │
-└────────────┴───────────────────────────────┘
-```
-
-Si intenta crear una matriz de tipos de datos incompatibles, ClickHouse produce una excepción:
-
-``` sql

-# Datetime {#data_type-datetime}
-
-Permite almacenar un instante en el tiempo, que se puede expresar como una fecha del calendario y una hora de un día.
-
-Sintaxis:
-
-``` sql
-DateTime([timezone])
-```
-
-Rango de valores: \[1970-01-01 00:00:00, 2105-12-31 23:59:59\].
-
-Resolución: 1 segundo.
-
-## Observaciones de uso {#usage-remarks}
-
-El punto en el tiempo se guarda como un [Timestamp de Unix](https://en.wikipedia.org/wiki/Unix_time), independientemente de la zona horaria o el horario de verano. Además, el `DateTime` tipo puede almacenar zona horaria que es la misma para toda la columna, que afecta a cómo los valores de la `DateTime` Los valores de tipo se muestran en formato de texto y cómo se analizan los valores especificados como cadenas (‘2020-01-01 05:00:01’). La zona horaria no se almacena en las filas de la tabla (o en el conjunto de resultados), sino que se almacena en los metadatos de la columna.
-Se puede encontrar una lista de zonas horarias compatibles en el [Base de datos de zonas horarias de IANA](https://www.iana.org/time-zones).
-El `tzdata` paquete, que contiene [Base de datos de zonas horarias de IANA](https://www.iana.org/time-zones), debe instalarse en el sistema. Utilice el `timedatectl list-timezones` comando para listar zonas horarias conocidas por un sistema local.
-
-Puede establecer explícitamente una zona horaria para `DateTime`-type columnas al crear una tabla. Si la zona horaria no está establecida, ClickHouse usa el valor [Zona horaria](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) parámetro en la configuración del servidor o la configuración del sistema operativo en el momento del inicio del servidor ClickHouse.
-
-El [Casa de clics-cliente](../../interfaces/cli.md) aplica la zona horaria del servidor de forma predeterminada si una zona horaria no se establece explícitamente al inicializar el tipo de datos. Para utilizar la zona horaria del cliente, ejecute `clickhouse-client` con el `--use_client_time_zone` parámetro.
-
-ClickHouse genera valores en `YYYY-MM-DD hh:mm:ss` formato de texto por defecto. Puede cambiar la salida con el [formatDateTime](../../sql-reference/functions/date-time-functions.md#formatdatetime) función.
-
-Al insertar datos en ClickHouse, puede usar diferentes formatos de cadenas de fecha y hora, dependiendo del valor de la [Date_time_input_format](../../operations/settings/settings.md#settings-date_time_input_format) configuración.

-## Ejemplos {#examples}
-
-**1.** Creación de una tabla con un `DateTime`-tipo de columna e insertar datos en ella:
-
-``` sql
-CREATE TABLE dt
-(
-    `timestamp` DateTime('Europe/Moscow'),
-    `event_id` UInt8
-)
-ENGINE = TinyLog;
-```
-
-``` sql
-INSERT INTO dt Values (1546300800, 1), ('2019-01-01 00:00:00', 2);
-```
-
-``` sql
-SELECT * FROM dt;

-└─────────────────────┴──────────┘
-```
-
--   Al insertar datetime como un entero, se trata como Unix Timestamp (UTC). `1546300800` representar `'2019-01-01 00:00:00'` UTC. Sin embargo, como `timestamp` columna tiene `Europe/Moscow` (UTC + 3) zona horaria especificada, al emitir como cadena, el valor se mostrará como `'2019-01-01 03:00:00'`
--   Al insertar el valor de cadena como fecha y hora, se trata como si estuviera en la zona horaria de la columna. `'2019-01-01 00:00:00'` será tratado como estar en `Europe/Moscow` zona horaria y guardado como `1546290000`.
-
-**2.** Filtrado en `DateTime` valor
-
-``` sql
-SELECT * FROM dt WHERE timestamp = toDateTime('2019-01-01 00:00:00', 'Europe/Moscow')

-# Decimal(P, S), Decimal32(S), Decimal64(S), Decimal128(S) {#decimalp-s-decimal32s-decimal64s-decimal128s}
-
-Números de punto fijo firmados que mantienen la precisión durante las operaciones de suma, resta y multiplicación. Para la división se descartan los dígitos menos significativos (no redondeados).
-
-## Parámetros {#parameters}
-
--   P - precisión. Rango válido: \[ 1 : 38 \]. Determina cuántos dígitos decimales puede tener el número (incluida la fracción).
--   S - escala. Rango válido: \[ 0 : P \]. Determina cuántos dígitos decimales puede tener la fracción.
-
-Dependiendo del valor del parámetro P Decimal(P, S) es un sinónimo de:
-- P de \[ 1 : 9 \] - para Decimal32(S)
-- P de \[ 10 : 18 \] - para Decimal64(S)
-- P de \[ 19 : 38 \] - para Decimal128(S)
-
-## Rangos de valores decimales {#decimal-value-ranges}
-
--   Decimal32(S) - ( -1 \* 10^(9 - S), 1 \* 10^(9 - S) )
--   Decimal64(S) - ( -1 \* 10^(18 - S), 1 \* 10^(18 - S) )
--   Decimal128(S) - ( -1 \* 10^(38 - S), 1 \* 10^(38 - S) )
-
-Por ejemplo, Decimal32(4) puede contener números de -99999.9999 a 99999.9999 con el paso 0.0001.
-
-## Representación interna {#internal-representation}
-
-Internamente, los datos se representan como enteros con signo normal con el ancho de bits respectivo. Los rangos de valores reales que se pueden almacenar en la memoria son un poco más grandes que los especificados anteriormente, que se verifican solo en la conversión de una cadena.
-
-Debido a que las CPU modernas no admiten enteros de 128 bits de forma nativa, las operaciones en Decimal128 se emulan. Debido a esto, Decimal128 funciona significativamente más lento que Decimal32 / Decimal64.
-
-## Operaciones y tipo de resultado {#operations-and-result-type}
-
-Las operaciones binarias en Decimal dan como resultado un tipo de resultado más amplio (con cualquier orden de argumentos).
-
--   `Decimal64(S1) <op> Decimal32(S2) -> Decimal64(S)`
--   `Decimal128(S1) <op> Decimal32(S2) -> Decimal128(S)`
--   `Decimal128(S1) <op> Decimal64(S2) -> Decimal128(S)`
-
-Reglas para la escala:
-
--   Sumar, restar: S = max(S1, S2).
--   multuply: S = S1 + S2.
--   división: S = S1.
-
-Para operaciones similares entre Decimal y enteros, el resultado es Decimal del mismo tamaño que un argumento.
-
-Las operaciones entre Decimal y Float32 / Float64 no están definidas. Si los necesita, puede convertir explícitamente uno de los argumentos utilizando toDecimal32, toDecimal64, toDecimal128 o toFloat32, toFloat64 builtins. Tenga en cuenta que el resultado perderá precisión y la conversión de tipo es una operación computacionalmente costosa.
-
-Algunas funciones en Decimal devuelven el resultado como Float64 (por ejemplo, var o stddev). Los cálculos intermedios aún se pueden realizar en Decimal, lo que podría dar lugar a resultados diferentes entre las entradas Float64 y Decimal con los mismos valores.
-
-## Comprobaciones de desbordamiento {#overflow-checks}
-
-Durante los cálculos en Decimal, pueden producirse desbordamientos de enteros. Los dígitos excesivos en una fracción se descartan (no se redondean). Los dígitos excesivos en la parte entera conducirán a una excepción.
-
-``` sql
-SELECT toDecimal32(2, 4) AS x, x / 3
-```
-
-``` text
-┌──────x─┬─divide(toDecimal32(2, 4), 3)─┐

-
-``` sql
-SELECT toDecimal32(4.2, 8) AS x, 6 * x
-```
-
-``` text
-DB::Exception: Decimal math overflow.
-```
-
-Las comprobaciones de desbordamiento conducen a la desaceleración de las operaciones. Si se sabe que los desbordamientos no son posibles, tiene sentido deshabilitar las verificaciones usando `decimal_check_overflow` configuración. Cuando las comprobaciones están deshabilitadas y se produce el desbordamiento, el resultado será incorrecto:
-
-``` sql
-SET decimal_check_overflow = 0;
-SELECT toDecimal32(4.2, 8) AS x, 6 * x

-
-Las comprobaciones de desbordamiento ocurren no solo en operaciones aritméticas sino también en la comparación de valores:
-
-``` sql
-SELECT toDecimal32(1, 8) < 100
-```
-
-``` text
-DB::Exception: Can't compare.

-
-Los dominios son tipos de propósito especial que agregan algunas características adicionales encima del tipo base existente, pero dejando intacto el formato en cable y en disco del tipo de datos subyacente. Por el momento, ClickHouse no admite dominios definidos por el usuario.
-
-Puede usar dominios en cualquier lugar que se pueda usar el tipo base correspondiente, por ejemplo:
-
--   Crear una columna de un tipo de dominio
--   Leer/escribir valores desde/a la columna de dominio
--   Úselo como un índice si un tipo base se puede usar como un índice
--   Funciones de llamada con valores de la columna de dominio
-
-### Características adicionales de los dominios {#extra-features-of-domains}
-
--   Nombre de tipo de columna explícito en `SHOW CREATE TABLE` o `DESCRIBE TABLE`
--   Entrada del formato humano-amistoso con `INSERT INTO domain_table(domain_column) VALUES(...)`
--   Salida al formato humano-amistoso para `SELECT domain_column FROM domain_table`
--   Carga de datos desde una fuente externa en el formato de uso humano: `INSERT INTO domain_table FORMAT CSV ...`
-
-### Limitacion {#limitations}
-
--   No se puede convertir la columna de índice del tipo base al tipo de dominio a través de `ALTER TABLE`.
--   No se pueden convertir implícitamente valores de cadena en valores de dominio al insertar datos de otra columna o tabla.
--   Domain no agrega restricciones en los valores almacenados.

-## IPv6 {#ipv6}
-
-`IPv6` es un dominio basado en `FixedString(16)` tipo y sirve como un reemplazo con tipo para almacenar valores IPv6. Proporciona un almacenamiento compacto con el formato de entrada-salida amigable para los humanos y la información sobre el tipo de columna en la inspección.
-
-### Uso básico {#basic-usage}
-
-``` sql
-CREATE TABLE hits (url String, from IPv6) ENGINE = MergeTree() ORDER BY url;
-
-DESCRIBE TABLE hits;
-```

-toc_title: Enum
----
-
-# Enum {#enum}
-
-Tipo enumerado que consta de valores con nombre.
-
-Los valores con nombre deben declararse como `'string' = integer` par. ClickHouse almacena solo números, pero admite operaciones con los valores a través de sus nombres.
-
-Soporta ClickHouse:
-
--   de 8 bits `Enum`. Puede contener hasta 256 valores enumerados en el `[-128, 127]` gama.
--   de 16 bits `Enum`. Puede contener hasta 65536 valores enumerados en el `[-32768, 32767]` gama.
-
-ClickHouse elige automáticamente el tipo de `Enum` cuando se insertan datos. También puede utilizar `Enum8` o `Enum16` para estar seguro en el tamaño de almacenamiento.
-
-## Ejemplos de uso {#usage-examples}
-
-Aquí creamos una tabla con un `Enum8('hello' = 1, 'world' = 2)` tipo columna:
-
-``` sql
-CREATE TABLE t_enum
-(
-    x Enum('hello' = 1, 'world' = 2)
-)
-ENGINE = TinyLog
-```
-
-Columna `x` sólo puede almacenar valores que se enumeran en la definición de tipo: `'hello'` o `'world'`. Si intenta guardar cualquier otro valor, ClickHouse generará una excepción. Tamaño de 8 bits para esto `Enum` se elige automáticamente.
-
-``` sql
-INSERT INTO t_enum VALUES ('hello'), ('world'), ('hello')
-```
-
-``` text
-Ok.
-```
-
-``` sql
-INSERT INTO t_enum values('a')
-```
-
-``` text
-Exception on client:
-Code: 49. DB::Exception: Unknown element 'a' for type Enum('hello' = 1, 'world' = 2)
-```
-
-Al consultar datos de la tabla, ClickHouse genera los valores de cadena de `Enum`.
-
-``` sql
-SELECT * FROM t_enum
-```
-
-``` text
-┌─x─────┐
-│ hello │
-│ world │
-│ hello │
-└───────┘
-```
-
-Si necesita ver los equivalentes numéricos de las filas, debe `Enum` valor a tipo entero.
-
-``` sql
-SELECT CAST(x, 'Int8') FROM t_enum
-```
-
-``` text
-┌─CAST(x, 'Int8')─┐
-│               1 │
-│               2 │
-│               1 │
-└─────────────────┘
-```
-
-Para crear un valor Enum en una consulta, también debe usar `CAST`.
-
-``` sql
-SELECT toTypeName(CAST('a', 'Enum(\'a\' = 1, \'b\' = 2)'))
-```
-
-``` text
-┌─toTypeName(CAST('a', 'Enum(\'a\' = 1, \'b\' = 2)'))─┐
-│ Enum8('a' = 1, 'b' = 2)                             │
-└─────────────────────────────────────────────────────┘
-```
-
-## Reglas generales y uso {#general-rules-and-usage}
-
-A cada uno de los valores se le asigna un número en el rango `-128 ... 127` para `Enum8` o en el rango `-32768 ... 32767` para `Enum16`. Todas las cadenas y números deben ser diferentes. Se permite una cadena vacía. Si se especifica este tipo (en una definición de tabla), los números pueden estar en un orden arbitrario. Sin embargo, el orden no importa.
-
-Ni la cadena ni el valor numérico en un `Enum` puede ser [NULL](../../sql-reference/syntax.md).
-
-Un `Enum` puede estar contenido en [NULL](nullable.md) tipo. Entonces, si crea una tabla usando la consulta
-
-``` sql
-CREATE TABLE t_enum_nullable
-(
-    x Nullable( Enum8('hello' = 1, 'world' = 2) )
-)
-ENGINE = TinyLog
-```
-
-puede almacenar no sólo `'hello'` y `'world'`, pero `NULL`, también.
-
-``` sql
-INSERT INTO t_enum_nullable Values('hello'),('world'),(NULL)
-```
-
-En RAM, un `Enum` columna se almacena de la misma manera que `Int8` o `Int16` de los valores numéricos correspondientes.
-
-Al leer en forma de texto, ClickHouse analiza el valor como una cadena y busca la cadena correspondiente del conjunto de valores Enum. Si no se encuentra, se lanza una excepción. Al leer en formato de texto, se lee la cadena y se busca el valor numérico correspondiente. Se lanzará una excepción si no se encuentra.
-Al escribir en forma de texto, escribe el valor como la cadena correspondiente. Si los datos de columna contienen elementos no utilizados (números que no son del conjunto válido), se produce una excepción. Al leer y escribir en forma binaria, funciona de la misma manera que para los tipos de datos Int8 e Int16.
-El valor predeterminado es el valor con el número más bajo.
-
-Durante `ORDER BY`, `GROUP BY`, `IN`, `DISTINCT` y así sucesivamente, las enumeraciones se comportan de la misma manera que los números correspondientes. Por ejemplo, ORDER BY los ordena numéricamente. Los operadores de igualdad y comparación funcionan de la misma manera en enumeraciones que en los valores numéricos subyacentes.
-
-Los valores de Enum no se pueden comparar con los números. Las enumeraciones se pueden comparar con una cadena constante. Si la cadena en comparación con no es un valor válido para el Enum, se lanzará una excepción. El operador IN es compatible con el Enum en el lado izquierdo y un conjunto de cadenas en el lado derecho. Las cadenas son los valores del Enum correspondiente.
-
-Most numeric and string operations are not defined for Enum values, e.g. adding a number to an Enum or concatenating a string to an Enum.
-Sin embargo, el Enum tiene un `toString` función que devuelve su valor de cadena.
-
-Los valores de Enum también se pueden convertir a tipos numéricos utilizando el `toT` función, donde T es un tipo numérico. Cuando T corresponde al tipo numérico subyacente de la enumeración, esta conversión es de costo cero.
-El tipo Enum se puede cambiar sin costo usando ALTER, si solo se cambia el conjunto de valores. Es posible agregar y eliminar miembros del Enum usando ALTER (eliminar es seguro solo si el valor eliminado nunca se ha usado en la tabla). Como salvaguardia, al cambiar el valor numérico de un miembro Enum definido previamente se producirá una excepción.
-
-Usando ALTER, es posible cambiar un Enum8 a un Enum16 o viceversa, al igual que cambiar un Int8 a Int16.

-toc_title: Cadena fija (N)
----
-
-# Cuerda fija {#fixedstring}
-
-Una cadena de longitud fija de `N` bytes (ni caracteres ni puntos de código).
-
-Para declarar una columna de `FixedString` tipo, utilice la siguiente sintaxis:
-
-``` sql
-<column_name> FixedString(N)
-```
-
-Donde `N` es un número natural.
-
-El `FixedString` tipo es eficiente cuando los datos tienen la longitud de `N` byte. En todos los demás casos, es probable que reduzca la eficiencia.
-
-Ejemplos de los valores que se pueden almacenar eficientemente en `FixedString`escrito columnas:
-
--   La representación binaria de direcciones IP (`FixedString(16)` para IPv6).
--   Language codes (ru_RU, en_US … ).
--   Currency codes (USD, RUB … ).
--   Representación binaria de hashes (`FixedString(16)` para MD5, `FixedString(32)` para SHA256).
-
-Para almacenar valores UUID, utilice el [UUID](uuid.md) tipo de datos.
-
-Al insertar los datos, ClickHouse:
-
--   Complementa una cadena con bytes nulos si la cadena contiene menos de `N` byte.
--   Lanza el `Too large value for FixedString(N)` excepción si la cadena contiene más de `N` byte.
-
-Al seleccionar los datos, ClickHouse no elimina los bytes nulos al final de la cadena. Si utiliza el `WHERE` cláusula, debe agregar bytes nulos manualmente para que coincida con el `FixedString` valor. En el ejemplo siguiente se muestra cómo utilizar el `WHERE` cláusula con `FixedString`.
-
-Consideremos la siguiente tabla con el único `FixedString(2)` columna:
-
-``` text
-┌─name──┐
-│ b     │
-└───────┘
-```
-
-Consulta `SELECT * FROM FixedStringTable WHERE a = 'b'` no devuelve ningún dato como resultado. Debemos complementar el patrón de filtro con bytes nulos.
-
-``` sql
-SELECT * FROM FixedStringTable
-WHERE a = 'b\0'
-```
-
-``` text
-┌─a─┐
-│ b │
-└───┘
-```
-
-Este comportamiento difiere de MySQL para el `CHAR` tipo (donde las cadenas se rellenan con espacios y los espacios se eliminan para la salida).
-
-Tenga en cuenta que la longitud del `FixedString(N)` el valor es constante. El [longitud](../../sql-reference/functions/array-functions.md#array_functions-length) función devuelve `N` incluso si el `FixedString(N)` sólo se rellena con bytes nulos, pero el valor [vaciar](../../sql-reference/functions/string-functions.md#empty) función devuelve `1` en este caso.

--   `Float64` - `double`
-
-Le recomendamos que almacene los datos en formato entero siempre que sea posible. Por ejemplo, convierta números de precisión fija en valores enteros, como importes monetarios o tiempos de carga de página en milisegundos.

-
--   El resultado del cálculo depende del método de cálculo (el tipo de procesador y la arquitectura del sistema informático).
--   Los cálculos de puntos flotantes pueden dar como resultado números como el infinito (`Inf`) y “not-a-number” (`NaN`). Esto debe tenerse en cuenta al procesar los resultados de los cálculos.

-# Nested(name1 Type1, Name2 Type2, …) {#nestedname1-type1-name2-type2}
-
-A nested data structure is like a table inside a cell. The parameters of a nested data structure – the column names and types – are specified the same way as in a [CREATE TABLE](../../../sql-reference/statements/create.md) consulta. Cada fila de la tabla puede corresponder a cualquier número de filas en una estructura de datos anidada.
-
-Ejemplo:
-
-``` sql
-CREATE TABLE test.visits
-(
-    CounterID UInt32,
-    StartDate Date,
-    Sign Int8,
-    IsNew UInt8,
-    VisitID UInt64,
-    UserID UInt64,
-    ...
-    Goals Nested
-    (
-        ID UInt32,
-        Serial UInt32,
-        EventTime DateTime,
-        Price Int64,
-        OrderID String,
-        CurrencyID UInt32
-    ),
-    ...
-) ENGINE = CollapsingMergeTree(StartDate, intHash32(UserID), (CounterID, StartDate, intHash32(UserID), VisitID), 8192, Sign)
-```
-
-Este ejemplo declara la `Goals` estructura de datos anidada, que contiene datos sobre conversiones (objetivos alcanzados). Cada fila en el ‘visits’ la tabla puede corresponder a cero o cualquier número de conversiones.
-
-Solo se admite un único nivel de anidamiento. Las columnas de estructuras anidadas que contienen matrices son equivalentes a matrices multidimensionales, por lo que tienen un soporte limitado (no hay soporte para almacenar estas columnas en tablas con el motor MergeTree).
-
-En la mayoría de los casos, cuando se trabaja con una estructura de datos anidada, sus columnas se especifican con nombres de columna separados por un punto. Estas columnas forman una matriz de tipos coincidentes. Todas las matrices de columnas de una sola estructura de datos anidados tienen la misma longitud.
-
-Ejemplo:
-
-``` sql

----
-
-# Nivel de Cifrado WEP) {#data_type-nullable}
-
-Permite almacenar marcador especial ([NULL](../../sql-reference/syntax.md)) que denota “missing value” junto con los valores normales permitidos por `TypeName`. Por ejemplo, un `Nullable(Int8)` tipo columna puede almacenar `Int8` valores de tipo, y las filas que no tienen un valor almacenarán `NULL`.
-
-Para un `TypeName`, no puede usar tipos de datos compuestos [Matriz](array.md) y [Tupla](tuple.md). Los tipos de datos compuestos pueden contener `Nullable` valores de tipo, como `Array(Nullable(Int8))`.
-
-A `Nullable` no se puede incluir en los índices de tabla.
-
-`NULL` es el valor predeterminado para cualquier `Nullable` tipo, a menos que se especifique lo contrario en la configuración del servidor ClickHouse.
-
-## Características de almacenamiento {#storage-features}
-
-Almacenar `Nullable` en una columna de tabla, ClickHouse usa un archivo separado con `NULL` máscaras además del archivo normal con valores. Las entradas en el archivo de máscaras permiten ClickHouse distinguir entre `NULL` y un valor predeterminado del tipo de datos correspondiente para cada fila de la tabla. Debido a un archivo adicional, `Nullable` La columna consume espacio de almacenamiento adicional en comparación con una normal similar.
-
-!!! info "Nota"
-    Utilizar `Nullable` casi siempre afecta negativamente al rendimiento, tenga esto en cuenta al diseñar sus bases de datos.

-# SimpleAggregateFunction {#data-type-simpleaggregatefunction}
-
-El tipo de dato `SimpleAggregateFunction(name, types_of_arguments…)` almacena el valor actual de la función agregada, no almacena su estado completo como hace [`AggregateFunction`](aggregatefunction.md). Esta optimización se puede aplicar a las funciones con la siguiente propiedad: el resultado de aplicar una función `f` a un conjunto de filas `S1 UNION ALL S2` se puede obtener aplicando `f` a partes de la fila establecida por separado, y luego aplicar de nuevo `f` los resultados: `f(S1 UNION ALL S2) = f(f(S1) UNION ALL f(S2))`. Un ejemplo de función con esta propiedad es la suma. Esta propiedad garantiza que los resultados de agregación parcial son suficientes para calcular el combinado, por lo que no tenemos que almacenar y procesar ningún dato adicional.
-
-La lista de functiones de agregación soportadas son:
-
--   [`any`](../../sql-reference/aggregate-functions/reference.md#agg_function-any)
--   [`anyLast`](../../sql-reference/aggregate-functions/reference.md#anylastx)
--   [`min`](../../sql-reference/aggregate-functions/reference.md#agg_function-min)
--   [`max`](../../sql-reference/aggregate-functions/reference.md#agg_function-max)
--   [`sum`](../../sql-reference/aggregate-functions/reference.md#agg_function-sum)
--   [`groupBitAnd`](../../sql-reference/aggregate-functions/reference.md#groupbitand)
--   [`groupBitOr`](../../sql-reference/aggregate-functions/reference.md#groupbitor)
--   [`groupBitXor`](../../sql-reference/aggregate-functions/reference.md#groupbitxor)
-
-Cuando se usa `SimpleAggregateFunction(func, Type)` el resultado es almacenado datos `Type` así que no necesita aplicar los suficos `-Merge`/`-State` a las funciones de agregación para usarlas. Para la misma función de agregación `SimpleAggregateFunction` tiene un mejor rendimiento que `AggregateFunction`.
-
-**Parámetros**
-
--   Nombre de la función de agregado.
--   Tipos de los argumentos de la función agregada.
-
-**Ejemplo**
-
-``` sql
-CREATE TABLE t

-    column2 SimpleAggregateFunction(any, String)
-) ENGINE = ...

----
-
-# Intervalo {#data-type-interval}
-
-La familia de tipos de datos que representan intervalos de fecha y hora. Los tipos resultantes del [INTERVAL](../../../sql-reference/operators/index.md#operator-interval) operador.
-
-!!! warning "Advertencia"
-    `Interval` los valores de tipo de datos no se pueden almacenar en tablas.
-
-Estructura:
-
--   Intervalo de tiempo como un valor entero sin signo.
--   Tipo de intervalo.
-
-Tipos de intervalo admitidos:
-
--   `SECOND`
--   `MINUTE`
--   `HOUR`
--   `DAY`
--   `WEEK`
--   `MONTH`
--   `QUARTER`
--   `YEAR`
-
-Para cada tipo de intervalo, hay un tipo de datos independiente. Por ejemplo, el `DAY` el intervalo corresponde a la `IntervalDay` tipo de datos:
-
-``` sql
-SELECT toTypeName(INTERVAL 4 DAY)
-```
-
-``` text
-┌─toTypeName(toIntervalDay(4))─┐
-│ IntervalDay                  │
-└──────────────────────────────┘
-```
-
-## Observaciones de uso {#data-type-interval-usage-remarks}
-
-Usted puede utilizar `Interval`-type valores en operaciones aritméticas con [Fecha](../../../sql-reference/data-types/date.md) y [FechaHora](../../../sql-reference/data-types/datetime.md)-type valores. Por ejemplo, puede agregar 4 días a la hora actual:
-
-``` sql
-SELECT now() as current_date_time, current_date_time + INTERVAL 4 DAY
-```
-
-``` text
-┌───current_date_time─┬─plus(now(), toIntervalDay(4))─┐
-│ 2019-10-23 10:58:45 │           2019-10-27 10:58:45 │
-└─────────────────────┴───────────────────────────────┘
-```
-
-Los intervalos con diferentes tipos no se pueden combinar. No puedes usar intervalos como `4 DAY 1 HOUR`. Especifique los intervalos en unidades que son más pequeñas o iguales que la unidad más pequeña del intervalo, por ejemplo, el intervalo `1 day and an hour` se puede expresar como `25 HOUR` o `90000 SECOND`.
-
-No puede realizar operaciones aritméticas con `Interval`-type valores, pero puede agregar intervalos de diferentes tipos en consecuencia a los valores en `Date` o `DateTime` tipos de datos. Por ejemplo:
-
-``` sql
-SELECT now() AS current_date_time, current_date_time + INTERVAL 4 DAY + INTERVAL 3 HOUR
-```
-
-``` text
-┌───current_date_time─┬─plus(plus(now(), toIntervalDay(4)), toIntervalHour(3))─┐
-│ 2019-10-23 11:16:28 │                                    2019-10-27 14:16:28 │
-└─────────────────────┴────────────────────────────────────────────────────────┘
-```
-
-La siguiente consulta provoca una excepción:
-
-``` sql
-select now() AS current_date_time, current_date_time + (INTERVAL 4 DAY + INTERVAL 3 HOUR)
-```
-
-``` text
-Received exception from server (version 19.14.1):

-Cuerdas de una longitud arbitraria. La longitud no está limitada. El valor puede contener un conjunto arbitrario de bytes, incluidos los bytes nulos.
-El tipo String reemplaza los tipos VARCHAR, BLOB, CLOB y otros de otros DBMS.
-
-## Codificación {#encodings}
-
-ClickHouse no tiene el concepto de codificaciones. Las cadenas pueden contener un conjunto arbitrario de bytes, que se almacenan y salen tal cual.
-Si necesita almacenar textos, le recomendamos que utilice la codificación UTF-8. Como mínimo, si su terminal usa UTF-8 (según lo recomendado), puede leer y escribir sus valores sin realizar conversiones.
-Del mismo modo, ciertas funciones para trabajar con cadenas tienen variaciones separadas que funcionan bajo el supuesto de que la cadena contiene un conjunto de bytes que representan un texto codificado en UTF-8.
-Por ejemplo, el ‘length’ función calcula la longitud de cadena en bytes, mientras que la ‘lengthUTF8’ función calcula la longitud de la cadena en puntos de código Unicode, suponiendo que el valor está codificado UTF-8.

-
-# Tuple(t1, T2, …) {#tuplet1-t2}
-
-Una tupla de elementos, cada uno con un individuo [tipo](index.md#data_types).
-
-Las tuplas se utilizan para la agrupación temporal de columnas. Las columnas se pueden agrupar cuando se usa una expresión IN en una consulta y para especificar ciertos parámetros formales de las funciones lambda. Para obtener más información, consulte las secciones [IN operadores](../../sql-reference/operators/in.md) y [Funciones de orden superior](../../sql-reference/functions/higher-order-functions.md).
-
-Las tuplas pueden ser el resultado de una consulta. En este caso, para formatos de texto distintos de JSON, los valores están separados por comas entre corchetes. En formatos JSON, las tuplas se generan como matrices (entre corchetes).
-
-## Creación de una tupla {#creating-a-tuple}
-
-Puedes usar una función para crear una tupla:
-
-``` sql
-tuple(T1, T2, ...)
-```
-
-Ejemplo de creación de una tupla:
-
-``` sql
-SELECT tuple(1,'a') AS x, toTypeName(x)
-```
-
-``` text
-┌─x───────┬─toTypeName(tuple(1, 'a'))─┐

-└─────────┴───────────────────────────┘
-```
-
-## Trabajar con tipos de datos {#working-with-data-types}
-
-Al crear una tupla sobre la marcha, ClickHouse detecta automáticamente el tipo de cada argumento como el mínimo de los tipos que pueden almacenar el valor del argumento. Si el argumento es [NULL](../../sql-reference/syntax.md#null-literal), el tipo del elemento de tupla es [NULL](nullable.md).
-
-Ejemplo de detección automática de tipos de datos:

-## Restricción {#restrictions}
-
-El tipo de datos UUID sólo admite funciones que [Cadena](string.md) tipo de datos también soporta (por ejemplo, [minuto](../../sql-reference/aggregate-functions/reference.md#agg_function-min), [máximo](../../sql-reference/aggregate-functions/reference.md#agg_function-max), y [contar](../../sql-reference/aggregate-functions/reference.md#agg_function-count)).
-
-El tipo de datos UUID no es compatible con operaciones aritméticas (por ejemplo, [abdominales](../../sql-reference/functions/arithmetic-functions.md#arithm_func-abs)) o funciones agregadas, tales como [resumir](../../sql-reference/aggregate-functions/reference.md#agg_function-sum) y [avg](../../sql-reference/aggregate-functions/reference.md#agg_function-avg).

-# Diccionarios jerárquicos {#hierarchical-dictionaries}
-
-ClickHouse soporta diccionarios jerárquicos con un [llave numérica](external-dicts-dict-structure.md#ext_dict-numeric-key).
-
-Mira la siguiente estructura jerárquica:
-
-``` text
-0 (Common parent)
-│
-├── 1 (Russia)
-│   │
-│   └── 2 (Moscow)
-│       │
-│       └── 3 (Center)
-│
-└── 4 (Great Britain)
-    │
-    └── 5 (London)
-```
-
-Esta jerarquía se puede expresar como la siguiente tabla de diccionario.
-
-| region_id | parent_region | nombre_región |
-|------------|----------------|----------------|
-| 1          | 0              | Rusia          |
-| 2          | 1              | Moscu          |
-| 3          | 2              | Centrar        |
-| 4          | 0              | Gran Bretaña   |
-| 5          | 4              | Londres        |
-
-Esta tabla contiene una columna `parent_region` que contiene la clave del padre más cercano para el elemento.
-
-ClickHouse soporta el [jerárquica](external-dicts-dict-structure.md#hierarchical-dict-attr) propiedad para [diccionario externo](index.md) atributo. Esta propiedad le permite configurar el diccionario jerárquico similar al descrito anteriormente.
-
-El [dictGetHierarchy](../../../sql-reference/functions/ext-dict-functions.md#dictgethierarchy) función le permite obtener la cadena principal de un elemento.
-
-Para nuestro ejemplo, la estructura del diccionario puede ser la siguiente:
-
-``` xml
-<dictionary>
-    <structure>
-        <id>
-            <name>region_id</name>
-        </id>
-
-        <attribute>
-            <name>parent_region</name>
-            <type>UInt64</type>
-            <null_value>0</null_value>
-            <hierarchical>true</hierarchical>
-        </attribute>
-
-        <attribute>
-            <name>region_name</name>
-            <type>String</type>
-            <null_value></null_value>
-        </attribute>

-toc_title: Almacenamiento de diccionarios en la memoria
----
-
-# Almacenamiento de diccionarios en la memoria {#dicts-external-dicts-dict-layout}
-
-Hay una variedad de formas de almacenar diccionarios en la memoria.
-
-Recomendamos [plano](#flat), [Hashed](#dicts-external_dicts_dict_layout-hashed) y [Método de codificación de datos:](#complex-key-hashed). que proporcionan una velocidad de procesamiento óptima.
-
-No se recomienda el almacenamiento en caché debido al rendimiento potencialmente bajo y las dificultades para seleccionar los parámetros óptimos. Lea más en la sección “[cache](#cache)”.
-
-Hay varias formas de mejorar el rendimiento del diccionario:
-
--   Llame a la función para trabajar con el diccionario después `GROUP BY`.
--   Marque los atributos para extraer como inyectivos. Un atributo se llama injective si diferentes valores de atributo corresponden a claves diferentes. Entonces, cuando `GROUP BY` utiliza una función que obtiene un valor de atributo mediante la clave, esta función se elimina automáticamente de `GROUP BY`.
-
-ClickHouse genera una excepción para errores con diccionarios. Ejemplos de errores:
-
--   No se pudo cargar el diccionario al que se accede.
--   Error al consultar un `cached` diccionario.
-
-Puede ver la lista de diccionarios externos y sus estados en el `system.dictionaries` tabla.
-
-La configuración se ve así:
-
-``` xml
-<yandex>
-    <dictionary>
-        ...
-        <layout>
-            <layout_type>
-                <!-- layout settings -->
-            </layout_type>
-        </layout>
-        ...
-    </dictionary>
-</yandex>
-```
-
-Correspondiente [Consulta DDL](../../statements/create.md#create-dictionary-query):
-
-``` sql
-CREATE DICTIONARY (...)
-...
-LAYOUT(LAYOUT_TYPE(param value)) -- layout settings
-...
-```
-
-## Maneras de almacenar diccionarios en la memoria {#ways-to-store-dictionaries-in-memory}
-
--   [plano](#flat)
--   [Hashed](#dicts-external_dicts_dict_layout-hashed)
--   [Sistema abierto.](#dicts-external_dicts_dict_layout-sparse_hashed)
--   [cache](#cache)
--   [directo](#direct)
--   [range_hashed](#range-hashed)
--   [Método de codificación de datos:](#complex-key-hashed)
--   [complejo_key_cache](#complex-key-cache)
--   [Método de codificación de datos:](#ip-trie)
-
-### plano {#flat}
-
-El diccionario está completamente almacenado en la memoria en forma de matrices planas. ¿Cuánta memoria usa el diccionario? La cantidad es proporcional al tamaño de la clave más grande (en el espacio utilizado).
-
-La clave del diccionario tiene el `UInt64` tipo y el valor está limitado a 500.000. Si se descubre una clave más grande al crear el diccionario, ClickHouse produce una excepción y no crea el diccionario.
-
-Se admiten todos los tipos de fuentes. Al actualizar, los datos (de un archivo o de una tabla) se leen en su totalidad.
-
-Este método proporciona el mejor rendimiento entre todos los métodos disponibles para almacenar el diccionario.
-
-Ejemplo de configuración:
-
-``` xml
-<layout>
-  <flat />
-</layout>
-```
-
-o
-
-``` sql
-LAYOUT(FLAT())
-```
-
-### Hashed {#dicts-external_dicts_dict_layout-hashed}
-
-El diccionario está completamente almacenado en la memoria en forma de una tabla hash. El diccionario puede contener cualquier número de elementos con cualquier identificador En la práctica, el número de claves puede alcanzar decenas de millones de elementos.
-
-Se admiten todos los tipos de fuentes. Al actualizar, los datos (de un archivo o de una tabla) se leen en su totalidad.
-
-Ejemplo de configuración:
-
-``` xml
-<layout>
-  <hashed />
-</layout>
-```
-
-o
-
-``` sql
-LAYOUT(HASHED())
-```
-
-### Sistema abierto {#dicts-external_dicts_dict_layout-sparse_hashed}
-
-Similar a `hashed`, pero usa menos memoria a favor más uso de CPU.
-
-Ejemplo de configuración:
-
-``` xml
-<layout>
-  <sparse_hashed />
-</layout>
-```
-
-``` sql
-LAYOUT(SPARSE_HASHED())
-```
-
-### Método de codificación de datos: {#complex-key-hashed}
-
-Este tipo de almacenamiento es para su uso con material compuesto [claves](external-dicts-dict-structure.md). Similar a `hashed`.
-
-Ejemplo de configuración:
-
-``` xml
-<layout>
-  <complex_key_hashed />
-</layout>
-```
-
-``` sql
-LAYOUT(COMPLEX_KEY_HASHED())
-```
-
-### range_hashed {#range-hashed}
-
-El diccionario se almacena en la memoria en forma de una tabla hash con una matriz ordenada de rangos y sus valores correspondientes.
-
-Este método de almacenamiento funciona de la misma manera que hash y permite el uso de intervalos de fecha / hora (tipo numérico arbitrario) además de la clave.
-
-Ejemplo: La tabla contiene descuentos para cada anunciante en el formato:
-
-``` text
-+---------|-------------|-------------|------+
-| advertiser id | discount start date | discount end date | amount |
-+===============+=====================+===================+========+
-| 123           | 2015-01-01          | 2015-01-15        | 0.15   |
-+---------|-------------|-------------|------+
-| 123           | 2015-01-16          | 2015-01-31        | 0.25   |
-+---------|-------------|-------------|------+
-| 456           | 2015-01-01          | 2015-01-15        | 0.05   |
-+---------|-------------|-------------|------+
-```
-
-Para utilizar un ejemplo para intervalos de fechas, defina el `range_min` y `range_max` elementos en el [estructura](external-dicts-dict-structure.md). Estos elementos deben contener elementos `name` y`type` (si `type` no se especifica, se utilizará el tipo predeterminado - Fecha). `type` puede ser de cualquier tipo numérico (Fecha / DateTime / UInt64 / Int32 / otros).
-
-Ejemplo:
-
-``` xml
-<structure>
-    <id>
-        <name>Id</name>
-    </id>
-    <range_min>
-        <name>first</name>
-        <type>Date</type>
-    </range_min>
-    <range_max>
-        <name>last</name>
-        <type>Date</type>
-    </range_max>
-    ...
-```
-
-o
-
-``` sql
-CREATE DICTIONARY somedict (
-    id UInt64,
-    first Date,
-    last Date
-)
-PRIMARY KEY id
-LAYOUT(RANGE_HASHED())
-RANGE(MIN first MAX last)
-```
-
-Para trabajar con estos diccionarios, debe pasar un argumento adicional al `dictGetT` función, para la que se selecciona un rango:
-
-``` sql
-dictGetT('dict_name', 'attr_name', id, date)
-```
-
-Esta función devuelve el valor para el `id`s y el intervalo de fechas que incluye la fecha pasada.
-
-Detalles del algoritmo:
-
--   Si el `id` no se encuentra o no se encuentra un rango para el `id` devuelve el valor predeterminado para el diccionario.
--   Si hay rangos superpuestos, puede usar cualquiera.
--   Si el delimitador de rango es `NULL` o una fecha no válida (como 1900-01-01 o 2039-01-01), el rango se deja abierto. La gama puede estar abierta en ambos lados.
-
-Ejemplo de configuración:
-
-``` xml
-<yandex>
-        <dictionary>
-
-                ...
-
-                <layout>
-                        <range_hashed />
-                </layout>
-
-                <structure>
-                        <id>
-                                <name>Abcdef</name>
-                        </id>
-                        <range_min>
-                                <name>StartTimeStamp</name>
-                                <type>UInt64</type>
-                        </range_min>
-                        <range_max>
-                                <name>EndTimeStamp</name>
-                                <type>UInt64</type>
-                        </range_max>
-                        <attribute>
-                                <name>XXXType</name>
-                                <type>String</type>
-                                <null_value />
-                        </attribute>
-                </structure>
-
-        </dictionary>
-</yandex>
-```
-
-o
-
-``` sql
-CREATE DICTIONARY somedict(
-    Abcdef UInt64,
-    StartTimeStamp UInt64,
-    EndTimeStamp UInt64,
-    XXXType String DEFAULT ''
-)
-PRIMARY KEY Abcdef
-RANGE(MIN StartTimeStamp MAX EndTimeStamp)
-```
-
-### cache {#cache}
-
-El diccionario se almacena en una memoria caché que tiene un número fijo de celdas. Estas celdas contienen elementos de uso frecuente.
-
-Al buscar un diccionario, primero se busca en la memoria caché. Para cada bloque de datos, todas las claves que no se encuentran en la memoria caché o están desactualizadas se solicitan desde el origen utilizando `SELECT attrs... FROM db.table WHERE id IN (k1, k2, ...)`. Los datos recibidos se escriben en la memoria caché.
-
-Para los diccionarios de caché, la caducidad [vida](external-dicts-dict-lifetime.md) de datos en la memoria caché se puede establecer. Si más tiempo que `lifetime` ha pasado desde que se cargaron los datos en una celda, el valor de la celda no se usa y se vuelve a solicitar la próxima vez que se deba usar.
-Esta es la menos efectiva de todas las formas de almacenar diccionarios. La velocidad de la memoria caché depende en gran medida de la configuración correcta y del escenario de uso. Un diccionario de tipo de caché funciona bien solo cuando las tasas de aciertos son lo suficientemente altas (recomendado 99% y superior). Puede ver la tasa de aciertos promedio en el `system.dictionaries` tabla.
-
-Para mejorar el rendimiento de la caché, utilice una subconsulta con `LIMIT`, y llame a la función con el diccionario externamente.
-
-Apoyar [fuente](external-dicts-dict-sources.md): MySQL, ClickHouse, ejecutable, HTTP.
-
-Ejemplo de configuración:
-
-``` xml
-<layout>
-    <cache>
-        <!-- The size of the cache, in number of cells. Rounded up to a power of two. -->
-        <size_in_cells>1000000000</size_in_cells>
-    </cache>
-</layout>
-```
-
-o
-
-``` sql
-LAYOUT(CACHE(SIZE_IN_CELLS 1000000000))
-```
-
-Establezca un tamaño de caché lo suficientemente grande. Necesitas experimentar para seleccionar el número de celdas:
-
-1.  Establecer algún valor.
-2.  Ejecute consultas hasta que la memoria caché esté completamente llena.
-3.  Evalúe el consumo de memoria utilizando el `system.dictionaries` tabla.
-4.  Aumente o disminuya el número de celdas hasta que se alcance el consumo de memoria requerido.
-
-!!! warning "Advertencia"
-    No use ClickHouse como fuente, ya que es lento procesar consultas con lecturas aleatorias.
-
-### complejo_key_cache {#complex-key-cache}
-
-Este tipo de almacenamiento es para su uso con material compuesto [claves](external-dicts-dict-structure.md). Similar a `cache`.
-
-### directo {#direct}
-
-El diccionario no se almacena en la memoria y va directamente a la fuente durante el procesamiento de una solicitud.
-
-La clave del diccionario tiene el `UInt64` tipo.
-
-Todos los tipos de [fuente](external-dicts-dict-sources.md), excepto los archivos locales, son compatibles.
-
-Ejemplo de configuración:
-
-``` xml
-<layout>
-  <direct />
-</layout>
-```
-
-o
-
-``` sql
-LAYOUT(DIRECT())
-```
-
-### Método de codificación de datos: {#ip-trie}
-
-Este tipo de almacenamiento sirve para asignar prefijos de red (direcciones IP) a metadatos como ASN.
-
-Ejemplo: La tabla contiene prefijos de red y su correspondiente número AS y código de país:
-
-``` text
-  +-----------|-----|------+
-  | prefix          | asn   | cca2   |
-  +=================+=======+========+
-  | 202.79.32.0/20  | 17501 | NP     |
-  +-----------|-----|------+
-  | 2620:0:870::/48 | 3856  | US     |
-  +-----------|-----|------+
-  | 2a02:6b8:1::/48 | 13238 | RU     |
-  +-----------|-----|------+
-  | 2001:db8::/32   | 65536 | ZZ     |
-  +-----------|-----|------+
-```
-
-Cuando se utiliza este tipo de diseño, la estructura debe tener una clave compuesta.
-
-Ejemplo:
-
-``` xml
-<structure>
-    <key>
-        <attribute>
-            <name>prefix</name>
-            <type>String</type>
-        </attribute>
-    </key>
-    <attribute>
-            <name>asn</name>
-            <type>UInt32</type>
-            <null_value />
-    </attribute>
-    <attribute>
-            <name>cca2</name>
-            <type>String</type>
-            <null_value>??</null_value>
-    </attribute>
-    ...
-```
-
-o
-
-``` sql
-CREATE DICTIONARY somedict (
-    prefix String,
-    asn UInt32,
-    cca2 String DEFAULT '??'
-)
-PRIMARY KEY prefix
-```
-
-La clave debe tener solo un atributo de tipo String que contenga un prefijo IP permitido. Todavía no se admiten otros tipos.
-
-Para consultas, debe utilizar las mismas funciones (`dictGetT` con una tupla) como para diccionarios con claves compuestas:
-
-``` sql
-dictGetT('dict_name', 'attr_name', tuple(ip))
-```
-
-La función toma cualquiera `UInt32` para IPv4, o `FixedString(16)` para IPv6:
-
-``` sql
-dictGetString('prefix', 'asn', tuple(IPv6StringToNum('2001:db8::1')))
-```
-
-Todavía no se admiten otros tipos. La función devuelve el atributo para el prefijo que corresponde a esta dirección IP. Si hay prefijos superpuestos, se devuelve el más específico.
-
-Los datos se almacenan en un `trie`. Debe encajar completamente en la RAM.

----
-
-# Actualizaciones del diccionario {#dictionary-updates}
-
-ClickHouse actualiza periódicamente los diccionarios. El intervalo de actualización para los diccionarios completamente descargados y el intervalo de invalidación para los diccionarios almacenados en caché se `<lifetime>` etiqueta en segundos.
-
-Las actualizaciones del diccionario (aparte de la carga para el primer uso) no bloquean las consultas. Durante las actualizaciones, se utiliza la versión anterior de un diccionario. Si se produce un error durante una actualización, el error se escribe en el registro del servidor y las consultas continúan utilizando la versión anterior de los diccionarios.
-
-Ejemplo de configuración:
-
-``` xml
-<dictionary>
-    ...
-    <lifetime>300</lifetime>
-    ...
-</dictionary>
-```
-
-``` sql
-CREATE DICTIONARY (...)
-...
-LIFETIME(300)
-...
-```
-
-Configuración `<lifetime>0</lifetime>` (`LIFETIME(0)`) impide que los diccionarios se actualicen.
-
-Puede establecer un intervalo de tiempo para las actualizaciones, y ClickHouse elegirá un tiempo uniformemente aleatorio dentro de este rango. Esto es necesario para distribuir la carga en la fuente del diccionario cuando se actualiza en una gran cantidad de servidores.
-
-Ejemplo de configuración:
-
-``` xml
-<dictionary>
-    ...
-    <lifetime>
-        <min>300</min>
-        <max>360</max>
-    </lifetime>
-    ...
-</dictionary>
-```
-
-o
-
-``` sql
-LIFETIME(MIN 300 MAX 360)
-```
-
-Si `<min>0</min>` y `<max>0</max>`, ClickHouse no vuelve a cargar el diccionario por tiempo de espera.
-En este caso, ClickHouse puede volver a cargar el diccionario anteriormente si el archivo de configuración del diccionario `SYSTEM RELOAD DICTIONARY` se ejecutó el comando.
-
-Al actualizar los diccionarios, el servidor ClickHouse aplica una lógica diferente según el tipo de [fuente](external-dicts-dict-sources.md):
-
-Al actualizar los diccionarios, el servidor ClickHouse aplica una lógica diferente según el tipo de [fuente](external-dicts-dict-sources.md):
-
--   Para un archivo de texto, comprueba el tiempo de modificación. Si la hora difiere de la hora previamente grabada, el diccionario se actualiza.
--   Para las tablas MyISAM, el tiempo de modificación se comprueba utilizando un `SHOW TABLE STATUS` consulta.
--   Los diccionarios de otras fuentes se actualizan cada vez de forma predeterminada.
-
-Para fuentes MySQL (InnoDB), ODBC y ClickHouse, puede configurar una consulta que actualizará los diccionarios solo si realmente cambiaron, en lugar de cada vez. Para ello, siga estos pasos:
-
--   La tabla del diccionario debe tener un campo que siempre cambie cuando se actualizan los datos de origen.
--   La configuración del origen debe especificar una consulta que recupere el campo de cambio. El servidor ClickHouse interpreta el resultado de la consulta como una fila, y si esta fila ha cambiado en relación con su estado anterior, el diccionario se actualiza. Especifique la consulta en el `<invalidate_query>` en la configuración de la [fuente](external-dicts-dict-sources.md).
-
-Ejemplo de configuración:
-
-``` xml
-<dictionary>
-    ...
-    <odbc>
-      ...
-      <invalidate_query>SELECT update_time FROM dictionary_source where id = 1</invalidate_query>

----
-
-# Fuentes de diccionarios externos {#dicts-external-dicts-dict-sources}
-
-Un diccionario externo se puede conectar desde muchas fuentes diferentes.
-
-Si el diccionario se configura usando xml-file, la configuración se ve así:
-
-``` xml
-<yandex>
-  <dictionary>
-    ...
-    <source>
-      <source_type>
-        <!-- Source configuration -->
-      </source_type>
-    </source>
-    ...
-  </dictionary>
-  ...
-</yandex>
-```
-
-En caso de [Consulta DDL](../../statements/create.md#create-dictionary-query), la configuración igual parecerá:
-
-``` sql
-CREATE DICTIONARY dict_name (...)
-...
-SOURCE(SOURCE_TYPE(param1 val1 ... paramN valN)) -- Source configuration
-...
-```
-
-El origen está configurado en el `source` apartado.
-
-Para tipos de origen [Archivo Local](#dicts-external_dicts_dict_sources-local_file), [Archivo ejecutable](#dicts-external_dicts_dict_sources-executable), [HTTP(s))](#dicts-external_dicts_dict_sources-http), [Haga clic en Casa](#dicts-external_dicts_dict_sources-clickhouse)
-ajustes opcionales están disponibles:
-
-``` xml
-<source>
-  <file>
-    <path>/opt/dictionaries/os.tsv</path>
-    <format>TabSeparated</format>
-  </file>
-  <settings>
-      <format_csv_allow_single_quotes>0</format_csv_allow_single_quotes>
-  </settings>
-</source>
-```
-

-## Archivo Local {#dicts-external_dicts_dict_sources-local_file}
-
-Ejemplo de configuración:
-
-``` xml
-<source>
-  <file>
-    <path>/opt/dictionaries/os.tsv</path>
-    <format>TabSeparated</format>
-  </file>
-</source>
-```
-
-o
-
-``` sql
-SOURCE(FILE(path '/opt/dictionaries/os.tsv' format 'TabSeparated'))
-```
-
-Configuración de campos:
-
--   `path` – The absolute path to the file.
--   `format` – The file format. All the formats described in “[Formato](../../../interfaces/formats.md#formats)” son compatibles.
-
-## Archivo ejecutable {#dicts-external_dicts_dict_sources-executable}
-
-Trabajar con archivos ejecutables depende de [cómo se almacena el diccionario en la memoria](external-dicts-dict-layout.md). Si el diccionario se almacena usando `cache` y `complex_key_cache`, ClickHouse solicita las claves necesarias enviando una solicitud al STDIN del archivo ejecutable. De lo contrario, ClickHouse inicia el archivo ejecutable y trata su salida como datos del diccionario.
-
-Ejemplo de configuración:
-
-``` xml
-<source>
-    <executable>
-        <command>cat /opt/dictionaries/os.tsv</command>
-        <format>TabSeparated</format>
-    </executable>
-</source>
-```
-
-o
-
-``` sql
-SOURCE(EXECUTABLE(command 'cat /opt/dictionaries/os.tsv' format 'TabSeparated'))
-```
-
-Configuración de campos:
-
--   `command` – The absolute path to the executable file, or the file name (if the program directory is written to `PATH`).
--   `format` – The file format. All the formats described in “[Formato](../../../interfaces/formats.md#formats)” son compatibles.
-
-## Http(s) {#dicts-external_dicts_dict_sources-http}
-
-Trabajar con un servidor HTTP depende de [cómo se almacena el diccionario en la memoria](external-dicts-dict-layout.md). Si el diccionario se almacena usando `cache` y `complex_key_cache`, ClickHouse solicita las claves necesarias enviando una solicitud a través del `POST` método.
-
-Ejemplo de configuración:
-
-``` xml
-<source>
-    <http>
-        <url>http://[::1]/os.tsv</url>
-        <format>TabSeparated</format>
-        <credentials>
-            <user>user</user>
-            <password>password</password>
-        </credentials>
-        <headers>
-            <header>
-                <name>API-KEY</name>
-                <value>key</value>
-            </header>
-        </headers>
-    </http>
-</source>
-```
-
-o
-
-``` sql
-SOURCE(HTTP(
-    url 'http://[::1]/os.tsv'
-    format 'TabSeparated'
-    credentials(user 'user' password 'password')
-    headers(header(name 'API-KEY' value 'key'))
-))
-```
-
-Para que ClickHouse tenga acceso a un recurso HTTPS, debe [configurar openSSL](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-openssl) en la configuración del servidor.
-
-Configuración de campos:
-
--   `url` – The source URL.
--   `format` – The file format. All the formats described in “[Formato](../../../interfaces/formats.md#formats)” son compatibles.
--   `credentials` – Basic HTTP authentication. Optional parameter.
-    -   `user` – Username required for the authentication.
-    -   `password` – Password required for the authentication.
--   `headers` – All custom HTTP headers entries used for the HTTP request. Optional parameter.
-    -   `header` – Single HTTP header entry.
-    -   `name` – Identifiant name used for the header send on the request.
-    -   `value` – Value set for a specific identifiant name.
-
-## ODBC {#dicts-external_dicts_dict_sources-odbc}
-
-Puede utilizar este método para conectar cualquier base de datos que tenga un controlador ODBC.
-
-Ejemplo de configuración:
-
-``` xml
-<source>
-    <odbc>
-        <db>DatabaseName</db>
-        <table>ShemaName.TableName</table>
-        <connection_string>DSN=some_parameters</connection_string>
-        <invalidate_query>SQL_QUERY</invalidate_query>
-    </odbc>
-</source>
-```
-
-o
-
-``` sql
-SOURCE(ODBC(
-    db 'DatabaseName'
-    table 'SchemaName.TableName'
-    connection_string 'DSN=some_parameters'
-    invalidate_query 'SQL_QUERY'
-))
-```
-
-Configuración de campos:
-
--   `db` – Name of the database. Omit it if the database name is set in the `<connection_string>` parámetros.
--   `table` – Name of the table and schema if exists.
--   `connection_string` – Connection string.
--   `invalidate_query` – Query for checking the dictionary status. Optional parameter. Read more in the section [Actualización de diccionarios](external-dicts-dict-lifetime.md).
-
-ClickHouse recibe símbolos de cotización del controlador ODBC y cita todas las configuraciones en las consultas al controlador, por lo que es necesario establecer el nombre de la tabla de acuerdo con el caso del nombre de la tabla en la base de datos.
-
-Si tiene problemas con las codificaciones al utilizar Oracle, consulte el [FAQ](../../../faq/general.md#oracle-odbc-encodings) artículo.
-
-### Vulnerabilidad conocida de la funcionalidad del diccionario ODBC {#known-vulnerability-of-the-odbc-dictionary-functionality}
-
-!!! attention "Atención"
-    Cuando se conecta a la base de datos a través del parámetro de conexión del controlador ODBC `Servername` puede ser sustituido. En este caso los valores de `USERNAME` y `PASSWORD` de `odbc.ini` se envían al servidor remoto y pueden verse comprometidos.
-
-**Ejemplo de uso inseguro**
-
-Vamos a configurar unixODBC para PostgreSQL. Contenido de `/etc/odbc.ini`:
-
-``` text
-[gregtest]
-Driver = /usr/lib/psqlodbca.so
-Servername = localhost
-PORT = 5432
-DATABASE = test_db
-#OPTION = 3
-USERNAME = test
-PASSWORD = test
-```
-
-Si luego realiza una consulta como
-
-``` sql
-SELECT * FROM odbc('DSN=gregtest;Servername=some-server.com', 'test_db');
-```
-
-El controlador ODBC enviará valores de `USERNAME` y `PASSWORD` de `odbc.ini` a `some-server.com`.
-
-### Ejemplo de Connecting Postgresql {#example-of-connecting-postgresql}
-
-Sistema operativo Ubuntu.
-
-Instalación de unixODBC y el controlador ODBC para PostgreSQL:
-
-``` bash
-$ sudo apt-get install -y unixodbc odbcinst odbc-postgresql
-```
-
-Configuración `/etc/odbc.ini` (o `~/.odbc.ini`):
-
-``` text
-    [DEFAULT]
-    Driver = myconnection
-
-    [myconnection]
-    Description         = PostgreSQL connection to my_db
-    Driver              = PostgreSQL Unicode
-    Database            = my_db
-    Servername          = 127.0.0.1
-    UserName            = username
-    Password            = password

-toc_title: Clave y campos del diccionario
----
-
-# Clave y campos del diccionario {#dictionary-key-and-fields}
-
-El `<structure>` cláusula describe la clave del diccionario y los campos disponibles para consultas.
-
-Descripción XML:
-
-``` xml
-<dictionary>
-    <structure>
-        <id>
-            <name>Id</name>
-        </id>
-
-        <attribute>
-            <!-- Attribute parameters -->
-        </attribute>
-
-        ...
-
-    </structure>
-</dictionary>
-```
-
-Los atributos se describen en los elementos:
-
--   `<id>` — [Columna clave](external-dicts-dict-structure.md#ext_dict_structure-key).
--   `<attribute>` — [Columna de datos](external-dicts-dict-structure.md#ext_dict_structure-attributes). Puede haber un número múltiple de atributos.
-
-Consulta DDL:
-
-``` sql
-CREATE DICTIONARY dict_name (
-    Id UInt64,
-    -- attributes
-)
-PRIMARY KEY Id
-...
-```
-
-Los atributos se describen en el cuerpo de la consulta:
-
--   `PRIMARY KEY` — [Columna clave](external-dicts-dict-structure.md#ext_dict_structure-key)
--   `AttrName AttrType` — [Columna de datos](external-dicts-dict-structure.md#ext_dict_structure-attributes). Puede haber un número múltiple de atributos.
-
-## Clave {#ext_dict_structure-key}
-
-ClickHouse admite los siguientes tipos de claves:
-
--   Tecla numérica. `UInt64`. Definido en el `<id>` etiqueta o usando `PRIMARY KEY` palabra clave.
--   Clave compuesta. Conjunto de valores de diferentes tipos. Definido en la etiqueta `<key>` o `PRIMARY KEY` palabra clave.
-
-Una estructura xml puede contener `<id>` o `<key>`. La consulta DDL debe contener `PRIMARY KEY`.
-
-!!! warning "Advertencia"
-    No debe describir la clave como un atributo.
-
-### Tecla numérica {#ext_dict-numeric-key}
-
-Tipo: `UInt64`.
-
-Ejemplo de configuración:
-
-``` xml
-<id>
-    <name>Id</name>
-</id>
-```
-
-Campos de configuración:
-
--   `name` – The name of the column with keys.
-
-Para consulta DDL:
-
-``` sql
-CREATE DICTIONARY (
-    Id UInt64,
-    ...
-)
-PRIMARY KEY Id
-...
-```
-
--   `PRIMARY KEY` – The name of the column with keys.
-
-### Clave compuesta {#composite-key}
-
-La clave puede ser un `tuple` de cualquier tipo de campo. El [diseño](external-dicts-dict-layout.md) en este caso debe ser `complex_key_hashed` o `complex_key_cache`.
-
-!!! tip "Consejo"
-    Una clave compuesta puede consistir en un solo elemento. Esto hace posible usar una cadena como clave, por ejemplo.
-
-La estructura clave se establece en el elemento `<key>`. Los campos clave se especifican en el mismo formato que el diccionario [atributo](external-dicts-dict-structure.md). Ejemplo:
-
-``` xml
-<structure>
-    <key>
-        <attribute>
-            <name>field1</name>
-            <type>String</type>
-        </attribute>
-        <attribute>
-            <name>field2</name>
-            <type>UInt32</type>
-        </attribute>
-        ...
-    </key>
-...
-```
-
-o
-
-``` sql
-CREATE DICTIONARY (
-    field1 String,
-    field2 String
-    ...
-)
-PRIMARY KEY field1, field2
-...
-```
-
-Para una consulta al `dictGet*` función, una tupla se pasa como la clave. Ejemplo: `dictGetString('dict_name', 'attr_name', tuple('string for field1', num_for_field2))`.
-
-## Atributo {#ext_dict_structure-attributes}
-
-Ejemplo de configuración:
-
-``` xml
-<structure>
-    ...
-    <attribute>
-        <name>Name</name>
-        <type>ClickHouseDataType</type>
-        <null_value></null_value>
-        <expression>rand64()</expression>
-        <hierarchical>true</hierarchical>
-        <injective>true</injective>
-        <is_object_id>true</is_object_id>
-    </attribute>
-</structure>
-```
-
-o

-# Diccionarios externos {#dicts-external-dicts}
-
-Puede agregar sus propios diccionarios de varias fuentes de datos. El origen de datos de un diccionario puede ser un archivo ejecutable o de texto local, un recurso HTTP u otro DBMS. Para obtener más información, consulte “[Fuentes para diccionarios externos](external-dicts-dict-sources.md)”.
-
-Haga clic en Casa:
-
--   Almacena total o parcialmente los diccionarios en RAM.
--   Actualiza periódicamente los diccionarios y carga dinámicamente los valores que faltan. En otras palabras, los diccionarios se pueden cargar dinámicamente.
--   Permite crear diccionarios externos con archivos xml o [Consultas DDL](../../statements/create.md#create-dictionary-query).
-
-La configuración de diccionarios externos se puede ubicar en uno o más archivos xml. La ruta de acceso a la configuración se especifica en el [Diccionarios_config](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-dictionaries_config) parámetro.
-
-Los diccionarios se pueden cargar en el inicio del servidor o en el primer uso, dependiendo de la [Diccionarios_lazy_load](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-dictionaries_lazy_load) configuración.
-
-El [diccionario](../../../operations/system-tables.md#system_tables-dictionaries) La tabla del sistema contiene información sobre los diccionarios configurados en el servidor. Para cada diccionario se puede encontrar allí:
-
--   Estado del diccionario.
--   Parámetros de configuración.
--   Métricas como la cantidad de RAM asignada para el diccionario o un número de consultas desde que el diccionario se cargó correctamente.
-
-El archivo de configuración del diccionario tiene el siguiente formato:
-
-``` xml
-<yandex>
-    <comment>An optional element with any content. Ignored by the ClickHouse server.</comment>
-
-    <!--Optional element. File name with substitutions-->
-    <include_from>/etc/metrika.xml</include_from>
-
-
-    <dictionary>
-        <!-- Dictionary configuration. -->
-        <!-- There can be any number of <dictionary> sections in the configuration file. -->
-    </dictionary>
-
-</yandex>
-```
-
-Usted puede [configurar](external-dicts-dict.md) cualquier número de diccionarios en el mismo archivo.
-
-[Consultas DDL para diccionarios](../../statements/create.md#create-dictionary-query) no requiere ningún registro adicional en la configuración del servidor. Permiten trabajar con diccionarios como entidades de primera clase, como tablas o vistas.
-
-!!! attention "Atención"
-    Puede convertir valores para un diccionario pequeño describiéndolo en un `SELECT` consulta (ver el [transformar](../../../sql-reference/functions/other-functions.md) función). Esta funcionalidad no está relacionada con diccionarios externos.

-# Diccionario {#dictionaries}
-
-Un diccionario es un mapeo (`key -> attributes`) que es conveniente para varios tipos de listas de referencia.
-
-ClickHouse admite funciones especiales para trabajar con diccionarios que se pueden usar en consultas. Es más fácil y más eficiente usar diccionarios con funciones que un `JOIN` con tablas de referencia.
-
-[NULL](../../sql-reference/syntax.md#null-literal) los valores no se pueden almacenar en un diccionario.
-
-Soporta ClickHouse:
-
--   [Diccionarios incorporados](internal-dicts.md#internal_dicts) con una específica [conjunto de funciones](../../sql-reference/functions/ym-dict-functions.md).
--   [Diccionarios complementarios (externos)](external-dictionaries/external-dicts.md#dicts-external-dicts) con un [conjunto de funciones](../../sql-reference/functions/ext-dict-functions.md).

-# Diccionarios internos {#internal_dicts}
-
-ClickHouse contiene una función integrada para trabajar con una geobase.
-
-Esto le permite:
-
--   Utilice el ID de una región para obtener su nombre en el idioma deseado.
--   Utilice el ID de una región para obtener el ID de una ciudad, área, distrito federal, país o continente.
--   Compruebe si una región es parte de otra región.
--   Obtener una cadena de regiones principales.
-
-Todas las funciones de apoyo “translocality,” la capacidad de utilizar simultáneamente diferentes perspectivas sobre la propiedad de la región. Para obtener más información, consulte la sección “Functions for working with Yandex.Metrica dictionaries”.
-
-Los diccionarios internos están deshabilitados en el paquete predeterminado.
-Para habilitarlos, descomente los parámetros `path_to_regions_hierarchy_file` y `path_to_regions_names_files` en el archivo de configuración del servidor.
-
-La geobase se carga desde archivos de texto.
-
-Coloque el `regions_hierarchy*.txt` archivos en el `path_to_regions_hierarchy_file` directorio. Este parámetro de configuración debe contener la ruta `regions_hierarchy.txt` archivo (la jerarquía regional predeterminada), y los otros archivos (`regions_hierarchy_ua.txt`) debe estar ubicado en el mismo directorio.
-
-Ponga el `regions_names_*.txt` archivos en el `path_to_regions_names_files` directorio.
-
-También puede crear estos archivos usted mismo. El formato de archivo es el siguiente:
-
-`regions_hierarchy*.txt`: TabSeparated (sin encabezado), columnas:
-
--   ID de la región (`UInt32`)
--   ID de región padre (`UInt32`)
--   tipo de región (`UInt8`): 1 - continente, 3 - país, 4 - distrito federal, 5 - región, 6 - ciudad; otros tipos no tienen valores
--   población (`UInt32`) — optional column
-
-`regions_names_*.txt`: TabSeparated (sin encabezado), columnas:
-
--   ID de la región (`UInt32`)
--   nombre de la región (`String`) — Can't contain tabs or line feeds, even escaped ones.
-
-Una matriz plana se usa para almacenar en RAM. Por esta razón, los ID no deberían ser más de un millón.
-
-Los diccionarios se pueden actualizar sin reiniciar el servidor. Sin embargo, el conjunto de diccionarios disponibles no se actualiza.
-Para las actualizaciones, se comprueban los tiempos de modificación de archivos. Si un archivo ha cambiado, el diccionario se actualiza.
-El intervalo para comprobar si hay cambios se configura en el `builtin_dictionaries_reload_interval` parámetro.
-Las actualizaciones del diccionario (aparte de la carga al primer uso) no bloquean las consultas. Durante las actualizaciones, las consultas utilizan las versiones anteriores de los diccionarios. Si se produce un error durante una actualización, el error se escribe en el registro del servidor y las consultas continúan utilizando la versión anterior de los diccionarios.
-
-Recomendamos actualizar periódicamente los diccionarios con la geobase. Durante una actualización, genere nuevos archivos y escríbalos en una ubicación separada. Cuando todo esté listo, cambie el nombre a los archivos utilizados por el servidor.
-
-También hay funciones para trabajar con identificadores de sistema operativo y Yandex.Motores de búsqueda Metrica, pero no deben ser utilizados.

-# Funciones aritméticas {#arithmetic-functions}
-
-Para todas las funciones aritméticas, el tipo de resultado se calcula como el tipo de número más pequeño en el que encaja el resultado, si existe dicho tipo. El mínimo se toma simultáneamente en función del número de bits, si está firmado y si flota. Si no hay suficientes bits, se toma el tipo de bit más alto.
-
-Ejemplo:
-
-``` sql
-SELECT toTypeName(0), toTypeName(0 + 0), toTypeName(0 + 0 + 0), toTypeName(0 + 0 + 0 + 0)
-```
-
-``` text
-┌─toTypeName(0)─┬─toTypeName(plus(0, 0))─┬─toTypeName(plus(plus(0, 0), 0))─┬─toTypeName(plus(plus(plus(0, 0), 0), 0))─┐
-│ UInt8         │ UInt16                 │ UInt32                          │ UInt64                                   │
-└───────────────┴────────────────────────┴─────────────────────────────────┴──────────────────────────────────────────┘
-```
-
-Las funciones aritméticas funcionan para cualquier par de tipos de UInt8, UInt16, UInt32, UInt64, Int8, Int16, Int32, Int64, Float32 o Float64.
-
-El desbordamiento se produce de la misma manera que en C ++.
-
-## más (a, b), a + b operador {#plusa-b-a-b-operator}
-
-Calcula la suma de los números.
-También puede agregar números enteros con una fecha o fecha y hora. En el caso de una fecha, agregar un entero significa agregar el número correspondiente de días. Para una fecha con hora, significa agregar el número correspondiente de segundos.
-
-## menos(a, b), a - b operador {#minusa-b-a-b-operator}
-
-Calcula la diferencia. El resultado siempre está firmado.
-
-You can also calculate integer numbers from a date or date with time. The idea is the same – see above for ‘plus’.
-
-## multiplicar(a, b) a \* b operador {#multiplya-b-a-b-operator}
-
-Calcula el producto de los números.
-
-## divide (a, b), operador a / b {#dividea-b-a-b-operator}
-
-Calcula el cociente de los números. El tipo de resultado es siempre un tipo de punto flotante.
-No es una división entera. Para la división de enteros, use el ‘intDiv’ función.
-Al dividir por cero obtienes ‘inf’, ‘-inf’, o ‘nan’.
-
-## Información de uso) {#intdiva-b}
-
-Calcula el cociente de los números. Se divide en enteros, redondeando hacia abajo (por el valor absoluto).
-Se produce una excepción al dividir por cero o al dividir un número negativo mínimo por menos uno.
-
-## IntDivOrZero (a, b) {#intdivorzeroa-b}
-
-Difiere de ‘intDiv’ en que devuelve cero al dividir por cero o al dividir un número negativo mínimo por menos uno.
-
-## modulo(a, b), a % b operador {#moduloa-b-a-b-operator}
-
-Calcula el resto después de la división.
-Si los argumentos son números de coma flotante, se convierten previamente en enteros eliminando la parte decimal.
-El resto se toma en el mismo sentido que en C ++. La división truncada se usa para números negativos.
-Se produce una excepción al dividir por cero o al dividir un número negativo mínimo por menos uno.
-
-## moduloOrZero (a, b) {#moduloorzeroa-b}
-
-Difiere de ‘modulo’ en que devuelve cero cuando el divisor es cero.
-
-## negate(a), -un operador {#negatea-a-operator}
-
-Calcula un número con el signo inverso. El resultado siempre está firmado.
-
-## abs (a) {#arithm_func-abs}
-
-Calcula el valor absoluto del número (a). Es decir, si un \<0, devuelve -a . Para los tipos sin firmar no hace nada. Para los tipos de enteros con signo, devuelve un número sin signo.
-
-## GCD (a, b) {#gcda-b}
-
-Devuelve el mayor divisor común de los números.
-Se produce una excepción al dividir por cero o al dividir un número negativo mínimo por menos uno.
-
-## Lcm(a, b) {#lcma-b}
-
-Devuelve el mínimo múltiplo común de los números.
-Se produce una excepción al dividir por cero o al dividir un número negativo mínimo por menos uno.

-# Funciones para trabajar con matrices {#functions-for-working-with-arrays}
-
-## vaciar {#function-empty}
-
-Devuelve 1 para una matriz vacía, o 0 para una matriz no vacía.
-El tipo de resultado es UInt8.
-La función también funciona para cadenas.
-
-## notEmpty {#function-notempty}
-
-Devuelve 0 para una matriz vacía, o 1 para una matriz no vacía.
-El tipo de resultado es UInt8.
-La función también funciona para cadenas.
-
-## longitud {#array_functions-length}
-
-Devuelve el número de elementos de la matriz.
-El tipo de resultado es UInt64.
-La función también funciona para cadenas.
-

-
-## Para obtener más información, consulta nuestra Política de privacidad y nuestras Condiciones de uso {#emptyarrayfloat32-emptyarrayfloat64}
-
-## emptyArrayDate, emptyArrayDateTime {#emptyarraydate-emptyarraydatetime}
-
-## emptyArrayString {#emptyarraystring}
-
-Acepta cero argumentos y devuelve una matriz vacía del tipo apropiado.
-
-## emptyArrayToSingle {#emptyarraytosingle}
-
-Acepta una matriz vacía y devuelve una matriz de un elemento que es igual al valor predeterminado.
-
-## rango(final), rango(inicio, fin \[, paso\]) {#rangeend-rangestart-end-step}
-
-Devuelve una matriz de números de principio a fin-1 por paso.
-Si el argumento `start` no se especifica, el valor predeterminado es 0.
-Si el argumento `step` no se especifica, el valor predeterminado es 1.
-Se comporta casi como pitónico `range`. Pero la diferencia es que todos los tipos de argumentos deben ser `UInt` numero.
-Por si acaso, se produce una excepción si se crean matrices con una longitud total de más de 100,000,000 de elementos en un bloque de datos.
-
-## array(x1, …), operator \[x1, …\] {#arrayx1-operator-x1}
-
-Crea una matriz a partir de los argumentos de la función.
-Los argumentos deben ser constantes y tener tipos que tengan el tipo común más pequeño. Se debe pasar al menos un argumento, porque de lo contrario no está claro qué tipo de matriz crear. Es decir, no puede usar esta función para crear una matriz vacía (para hacerlo, use el ‘emptyArray\*’ función descrita anteriormente).
-Devuelve un ‘Array(T)’ tipo resultado, donde ‘T’ es el tipo común más pequeño de los argumentos pasados.
-
-## arrayConcat {#arrayconcat}
-
-Combina matrices pasadas como argumentos.
-
-``` sql
-arrayConcat(arrays)
-```
-
-**Parámetros**
-
--   `arrays` – Arbitrary number of arguments of [Matriz](../../sql-reference/data-types/array.md) tipo.
-    **Ejemplo**
-
-<!-- -->
-
-``` sql
-SELECT arrayConcat([1, 2], [3, 4], [5, 6]) AS res
-```
-
-``` text

-```
-
-## Por ejemplo, el operador arr\[n\] {#arrayelementarr-n-operator-arrn}
-
-Obtener el elemento con el índice `n` de la matriz `arr`. `n` debe ser de cualquier tipo entero.
-Los índices de una matriz comienzan desde uno.
-Los índices negativos son compatibles. En este caso, selecciona el elemento correspondiente numerado desde el final. Por ejemplo, `arr[-1]` es el último elemento de la matriz.
-
-Si el índice cae fuera de los límites de una matriz, devuelve algún valor predeterminado (0 para números, una cadena vacía para cadenas, etc.), a excepción del caso con una matriz no constante y un índice constante 0 (en este caso habrá un error `Array indices are 1-based`).
-
-## Tiene(arr, elem) {#hasarr-elem}
-
-Comprueba si el ‘arr’ la matriz tiene el ‘elem’ elemento.
-Devuelve 0 si el elemento no está en la matriz, o 1 si es.
-
-`NULL` se procesa como un valor.
-
-``` sql
-SELECT has([1, 2, NULL], NULL)
-```
-
-``` text
-┌─has([1, 2, NULL], NULL)─┐
-│                       1 │
-└─────────────────────────┘
-```
-
-## TieneTodo {#hasall}
-
-Comprueba si una matriz es un subconjunto de otra.
-
-``` sql
-hasAll(set, subset)
-```
-
-**Parámetros**
-
--   `set` – Array of any type with a set of elements.
--   `subset` – Array of any type with elements that should be tested to be a subset of `set`.
-
-**Valores de retorno**
-
--   `1`, si `set` contiene todos los elementos de `subset`.
--   `0`, de lo contrario.
-
-**Propiedades peculiares**
-
--   Una matriz vacía es un subconjunto de cualquier matriz.
--   `Null` procesado como un valor.
--   El orden de los valores en ambas matrices no importa.
-
-**Ejemplos**
-
-`SELECT hasAll([], [])` devoluciones 1.
-
-`SELECT hasAll([1, Null], [Null])` devoluciones 1.
-
-`SELECT hasAll([1.0, 2, 3, 4], [1, 3])` devoluciones 1.
-
-`SELECT hasAll(['a', 'b'], ['a'])` devoluciones 1.
-
-`SELECT hasAll([1], ['a'])` devuelve 0.
-
-`SELECT hasAll([[1, 2], [3, 4]], [[1, 2], [3, 5]])` devuelve 0.
-
-## TieneCualquier {#hasany}
-
-Comprueba si dos matrices tienen intersección por algunos elementos.
-
-``` sql
-hasAny(array1, array2)
-```
-
-**Parámetros**
-
--   `array1` – Array of any type with a set of elements.
--   `array2` – Array of any type with a set of elements.
-
-**Valores de retorno**
-
--   `1`, si `array1` y `array2` tienen un elemento similar al menos.
--   `0`, de lo contrario.
-
-**Propiedades peculiares**
-
--   `Null` procesado como un valor.
--   El orden de los valores en ambas matrices no importa.
-
-**Ejemplos**
-
-`SELECT hasAny([1], [])` devoluciones `0`.
-
-`SELECT hasAny([Null], [Null, 1])` devoluciones `1`.
-
-`SELECT hasAny([-128, 1., 512], [1])` devoluciones `1`.
-
-`SELECT hasAny([[1, 2], [3, 4]], ['a', 'c'])` devoluciones `0`.
-
-`SELECT hasAll([[1, 2], [3, 4]], [[1, 2], [1, 2]])` devoluciones `1`.
-
-## ¿Cómo puedo hacerlo?) {#indexofarr-x}
-
-Devuelve el índice de la primera ‘x’ elemento (comenzando desde 1) si está en la matriz, o 0 si no lo está.
-
-Ejemplo:
-
-``` sql
-SELECT indexOf([1, 3, NULL, NULL], NULL)
-```
-
-``` text
-┌─indexOf([1, 3, NULL, NULL], NULL)─┐
-│                                 3 │
-└───────────────────────────────────┘
-```
-
-Elementos establecidos en `NULL` se manejan como valores normales.
-
-## Cuenta igual (arr, x) {#countequalarr-x}
-
-Devuelve el número de elementos de la matriz igual a x. Equivalente a arrayCount (elem -\> elem = x, arr).
-
-`NULL` los elementos se manejan como valores separados.
-
-Ejemplo:
-
-``` sql
-SELECT countEqual([1, 2, NULL, NULL], NULL)
-```
-
-``` text
-┌─countEqual([1, 2, NULL, NULL], NULL)─┐
-│                                    2 │
-└──────────────────────────────────────┘
-```
-
-## Información detallada) {#array_functions-arrayenumerate}
-
-Returns the array \[1, 2, 3, …, length (arr) \]
-
-Esta función se utiliza normalmente con ARRAY JOIN. Permite contar algo solo una vez para cada matriz después de aplicar ARRAY JOIN . Ejemplo:
-
-``` sql
-SELECT
-    count() AS Reaches,
-    countIf(num = 1) AS Hits
-FROM test.hits
-ARRAY JOIN
-    GoalsReached,
-    arrayEnumerate(GoalsReached) AS num
-WHERE CounterID = 160656
-LIMIT 10
-```
-
-``` text
-┌─Reaches─┬──Hits─┐
-│   95606 │ 31406 │
-└─────────┴───────┘
-```
-
-En este ejemplo, Reaches es el número de conversiones (las cadenas recibidas después de aplicar ARRAY JOIN) y Hits es el número de páginas vistas (cadenas antes de ARRAY JOIN). En este caso particular, puede obtener el mismo resultado de una manera más fácil:
-
-``` sql
-SELECT
-    sum(length(GoalsReached)) AS Reaches,
-    count() AS Hits
-FROM test.hits
-WHERE (CounterID = 160656) AND notEmpty(GoalsReached)
-```
-
-``` text
-┌─Reaches─┬──Hits─┐
-│   95606 │ 31406 │
-└─────────┴───────┘
-```
-
-Esta función también se puede utilizar en funciones de orden superior. Por ejemplo, puede usarlo para obtener índices de matriz para elementos que coinciden con una condición.
-
-## arrayEnumerateUniq(arr, …) {#arrayenumerateuniqarr}
-
-Devuelve una matriz del mismo tamaño que la matriz de origen, indicando para cada elemento cuál es su posición entre los elementos con el mismo valor.
-Por ejemplo: arrayEnumerateUniq(\[10, 20, 10, 30\]) = \[1, 1, 2, 1\].
-
-Esta función es útil cuando se utiliza ARRAY JOIN y la agregación de elementos de matriz.
-Ejemplo:
-
-``` sql
-SELECT
-    Goals.ID AS GoalID,
-    sum(Sign) AS Reaches,
-    sumIf(Sign, num = 1) AS Visits
-FROM test.visits
-ARRAY JOIN
-    Goals,
-    arrayEnumerateUniq(Goals.ID) AS num
-WHERE CounterID = 160656
-GROUP BY GoalID
-ORDER BY Reaches DESC
-LIMIT 10
-```
-
-``` text
-┌──GoalID─┬─Reaches─┬─Visits─┐
-│   53225 │    3214 │   1097 │
-│ 2825062 │    3188 │   1097 │
-│   56600 │    2803 │    488 │
-│ 1989037 │    2401 │    365 │
-│ 2830064 │    2396 │    910 │
-│ 1113562 │    2372 │    373 │
-│ 3270895 │    2262 │    812 │
-│ 1084657 │    2262 │    345 │
-│   56599 │    2260 │    799 │
-│ 3271094 │    2256 │    812 │
-└─────────┴─────────┴────────┘
-```
-
-En este ejemplo, cada ID de objetivo tiene un cálculo del número de conversiones (cada elemento de la estructura de datos anidados Objetivos es un objetivo alcanzado, al que nos referimos como conversión) y el número de sesiones. Sin ARRAY JOIN, habríamos contado el número de sesiones como sum(Sign) . Pero en este caso particular, las filas se multiplicaron por la estructura de Objetivos anidados, por lo que para contar cada sesión una vez después de esto, aplicamos una condición al valor de la función arrayEnumerateUniq(Goals.ID) .
-
-La función arrayEnumerateUniq puede tomar varias matrices del mismo tamaño que los argumentos. En este caso, la singularidad se considera para tuplas de elementos en las mismas posiciones en todas las matrices.
-
-``` sql
-SELECT arrayEnumerateUniq([1, 1, 1, 2, 2, 2], [1, 1, 2, 1, 1, 2]) AS res
-```
-
-``` text
-┌─res───────────┐
-│ [1,2,1,1,2,1] │
-└───────────────┘
-```
-
-Esto es necesario cuando se utiliza ARRAY JOIN con una estructura de datos anidados y una agregación adicional a través de múltiples elementos de esta estructura.
-

-
-Quita el último elemento de la matriz.
-
-``` sql

-```
-
-## arrayPopFront {#arraypopfront}

-
-**Parámetros**
-
--   `array` – Array.
--   `single_value` – A single value. Only numbers can be added to an array with numbers, and only strings can be added to an array of strings. When adding numbers, ClickHouse automatically sets the `single_value` tipo para el tipo de datos de la matriz. Para obtener más información sobre los tipos de datos en ClickHouse, consulte “[Tipos de datos](../../sql-reference/data-types/index.md#data_types)”. Puede ser `NULL`. La función agrega un `NULL` elemento de matriz a una matriz, y el tipo de elementos de matriz se convierte en `Nullable`.
-
-**Ejemplo**

-```
-
-**Parámetros:**
-
--   `array` — Array.
--   `size` — Required length of the array.
-    -   Si `size` es menor que el tamaño original de la matriz, la matriz se trunca desde la derecha.
--   Si `size` es mayor que el tamaño inicial de la matriz, la matriz se extiende a la derecha con `extender` valores predeterminados para el tipo de datos de los elementos de la matriz.

-```
-
-## arraySlice {#arrayslice}
-
-Devuelve una porción de la matriz.
-
-``` sql
-arraySlice(array, offset[, length])
-```
-
-**Parámetros**
-
--   `array` – Array of data.
--   `offset` – Indent from the edge of the array. A positive value indicates an offset on the left, and a negative value is an indent on the right. Numbering of the array items begins with 1.
--   `length` - La longitud de la porción requerida. Si especifica un valor negativo, la función devuelve un segmento abierto `[offset, array_length - length)`. Si omite el valor, la función devuelve el sector `[offset, the_end_of_array]`.
-
-**Ejemplo**
-
-``` sql
-SELECT arraySlice([1, 2, NULL, 4, 5], 2, 3) AS res
-```
-
-``` text
-┌─res────────┐
-│ [2,NULL,4] │
-└────────────┘
-```
-
-Elementos de matriz establecidos en `NULL` se manejan como valores normales.
-
-## arraySort(\[func,\] arr, …) {#array_functions-sort}
-
-Ordena los elementos del `arr` matriz en orden ascendente. Si el `func` se especifica la función, el orden de clasificación está determinado por el resultado `func` función aplicada a los elementos de la matriz. Si `func` acepta múltiples argumentos, el `arraySort` función se pasa varias matrices que los argumentos de `func` corresponderá a. Los ejemplos detallados se muestran al final de `arraySort` descripci.
-
-Ejemplo de clasificación de valores enteros:
-
-``` sql
-SELECT arraySort([1, 3, 3, 0]);
-```
-
-``` text
-┌─arraySort([1, 3, 3, 0])─┐
-│ [0,1,3,3]               │
-└─────────────────────────┘
-```
-
-Ejemplo de ordenación de valores de cadena:
-
-``` sql
-SELECT arraySort(['hello', 'world', '!']);
-```
-
-``` text
-┌─arraySort(['hello', 'world', '!'])─┐
-│ ['!','hello','world']              │
-└────────────────────────────────────┘
-```
-
-Considere el siguiente orden de clasificación `NULL`, `NaN` y `Inf` valor:
-
-``` sql
-SELECT arraySort([1, nan, 2, NULL, 3, nan, -4, NULL, inf, -inf]);
-```
-
-``` text
-┌─arraySort([1, nan, 2, NULL, 3, nan, -4, NULL, inf, -inf])─┐
-│ [-inf,-4,1,2,3,inf,nan,nan,NULL,NULL]                     │
-└───────────────────────────────────────────────────────────┘
-```
-
--   `-Inf` los valores son los primeros en la matriz.
--   `NULL` los valores son los últimos en la matriz.
--   `NaN` los valores están justo antes `NULL`.
--   `Inf` los valores están justo antes `NaN`.
-
-Tenga en cuenta que `arraySort` es una [función de orden superior](higher-order-functions.md). Puede pasarle una función lambda como primer argumento. En este caso, el orden de clasificación está determinado por el resultado de la función lambda aplicada a los elementos de la matriz.
-
-Consideremos el siguiente ejemplo:
-
-``` sql
-SELECT arraySort((x) -> -x, [1, 2, 3]) as res;
-```
-
-``` text
-┌─res─────┐
-│ [3,2,1] │
-└─────────┘
-```
-
-For each element of the source array, the lambda function returns the sorting key, that is, \[1 –\> -1, 2 –\> -2, 3 –\> -3\]. Since the `arraySort` función ordena las teclas en orden ascendente, el resultado es \[3, 2, 1\]. Por lo tanto, el `(x) –> -x` la función lambda establece la [orden descendente](#array_functions-reverse-sort) en una clasificación.
-
-La función lambda puede aceptar múltiples argumentos. En este caso, debe pasar el `arraySort` función varias matrices de idéntica longitud a las que corresponderán los argumentos de la función lambda. La matriz resultante constará de elementos de la primera matriz de entrada; los elementos de la siguiente matriz de entrada especifican las claves de clasificación. Por ejemplo:
-
-``` sql
-SELECT arraySort((x, y) -> y, ['hello', 'world'], [2, 1]) as res;
-```
-
-``` text
-┌─res────────────────┐
-│ ['world', 'hello'] │
-└────────────────────┘
-```
-
-Aquí, los elementos que se pasan en la segunda matriz (\[2, 1\]) definen una clave de ordenación para el elemento correspondiente de la matriz de origen (\[‘hello’, ‘world’Es decir,, \[‘hello’ –\> 2, ‘world’ –\> 1\]. Since the lambda function doesn't use `x`, los valores reales de la matriz de origen no afectan el orden en el resultado. Tan, ‘hello’ será el segundo elemento en el resultado, y ‘world’ será la primera.
-
-Otros ejemplos se muestran a continuación.

-!!! note "Nota"
-    Para mejorar la eficiencia de clasificación, el [Transformación de Schwartzian](https://en.wikipedia.org/wiki/Schwartzian_transform) se utiliza.
-
-## arrayReverseSort(\[func,\] arr, …) {#array_functions-reverse-sort}
-
-Ordena los elementos del `arr` matriz en orden descendente. Si el `func` se especifica la función, `arr` se ordena de acuerdo con el resultado de la `func` función aplicada a los elementos de la matriz, y luego la matriz ordenada se invierte. Si `func` acepta múltiples argumentos, el `arrayReverseSort` función se pasa varias matrices que los argumentos de `func` corresponderá a. Los ejemplos detallados se muestran al final de `arrayReverseSort` descripci.
-
-Ejemplo de clasificación de valores enteros:
-
-``` sql
-SELECT arrayReverseSort([1, 3, 3, 0]);
-```
-
-``` text
-┌─arrayReverseSort([1, 3, 3, 0])─┐
-│ [3,3,1,0]                      │
-└────────────────────────────────┘
-```
-
-Ejemplo de ordenación de valores de cadena:
-
-``` sql
-SELECT arrayReverseSort(['hello', 'world', '!']);
-```
-
-``` text
-┌─arrayReverseSort(['hello', 'world', '!'])─┐
-│ ['world','hello','!']                     │
-└───────────────────────────────────────────┘
-```
-
-Considere el siguiente orden de clasificación `NULL`, `NaN` y `Inf` valor:
-
-``` sql
-SELECT arrayReverseSort([1, nan, 2, NULL, 3, nan, -4, NULL, inf, -inf]) as res;
-```
-
-``` text
-┌─res───────────────────────────────────┐
-│ [inf,3,2,1,-4,-inf,nan,nan,NULL,NULL] │
-└───────────────────────────────────────┘
-```
-
--   `Inf` los valores son los primeros en la matriz.
--   `NULL` los valores son los últimos en la matriz.
--   `NaN` los valores están justo antes `NULL`.
--   `-Inf` los valores están justo antes `NaN`.
-
-Tenga en cuenta que el `arrayReverseSort` es una [función de orden superior](higher-order-functions.md). Puede pasarle una función lambda como primer argumento. Ejemplo se muestra a continuación.
-
-``` sql
-SELECT arrayReverseSort((x) -> -x, [1, 2, 3]) as res;
-```
-
-``` text
-┌─res─────┐
-│ [1,2,3] │
-└─────────┘
-```
-
-La matriz se ordena de la siguiente manera:
-
-1.  Al principio, la matriz de origen (\[1, 2, 3\]) se ordena de acuerdo con el resultado de la función lambda aplicada a los elementos de la matriz. El resultado es una matriz \[3, 2, 1\].
-2.  Matriz que se obtiene en el paso anterior, se invierte. Entonces, el resultado final es \[1, 2, 3\].
-
-La función lambda puede aceptar múltiples argumentos. En este caso, debe pasar el `arrayReverseSort` función varias matrices de idéntica longitud a las que corresponderán los argumentos de la función lambda. La matriz resultante constará de elementos de la primera matriz de entrada; los elementos de la siguiente matriz de entrada especifican las claves de clasificación. Por ejemplo:
-
-``` sql
-SELECT arrayReverseSort((x, y) -> y, ['hello', 'world'], [2, 1]) as res;
-```
-
-``` text
-┌─res───────────────┐
-│ ['hello','world'] │
-└───────────────────┘
-```
-
-En este ejemplo, la matriz se ordena de la siguiente manera:
-
-1.  Al principio, la matriz de origen (\[‘hello’, ‘world’\]) se ordena de acuerdo con el resultado de la función lambda aplicada a los elementos de las matrices. Los elementos que se pasan en la segunda matriz (\[2, 1\]), definen las claves de ordenación para los elementos correspondientes de la matriz de origen. El resultado es una matriz \[‘world’, ‘hello’\].
-2.  Matriz que se ordenó en el paso anterior, se invierte. Entonces, el resultado final es \[‘hello’, ‘world’\].
-
-Otros ejemplos se muestran a continuación.
-
-``` sql
-SELECT arrayReverseSort((x, y) -> y, [4, 3, 5], ['a', 'b', 'c']) AS res;
-```
-
-``` text

-
-## arrayUniq(arr, …) {#arrayuniqarr}
-
-Si se pasa un argumento, cuenta el número de elementos diferentes en la matriz.
-Si se pasan varios argumentos, cuenta el número de tuplas diferentes de elementos en las posiciones correspondientes en múltiples matrices.
-
-Si desea obtener una lista de elementos únicos en una matriz, puede usar arrayReduce(‘groupUniqArray’ arr).

-# arrayJoin función {#functions_arrayjoin}
-
-Esta es una función muy inusual.
-
-Las funciones normales no cambian un conjunto de filas, sino que simplemente cambian los valores en cada fila (mapa).
-Las funciones agregadas comprimen un conjunto de filas (doblar o reducir).
-El ‘arrayJoin’ función toma cada fila y genera un conjunto de filas (desplegar).
-
-Esta función toma una matriz como argumento y propaga la fila de origen a varias filas para el número de elementos de la matriz.
-Todos los valores de las columnas simplemente se copian, excepto los valores de la columna donde se aplica esta función; se reemplaza con el valor de matriz correspondiente.
-
-Una consulta puede usar múltiples `arrayJoin` función. En este caso, la transformación se realiza varias veces.
-
-Tenga en cuenta la sintaxis ARRAY JOIN en la consulta SELECT, que proporciona posibilidades más amplias.
-
-Ejemplo:
-
-``` sql
-SELECT arrayJoin([1, 2, 3] AS src) AS dst, 'Hello', src
-```
-
-``` text

-# Funciones de mapa de bits {#bitmap-functions}
-
-Las funciones de mapa de bits funcionan para dos mapas de bits Cálculo del valor del objeto, es devolver un nuevo mapa de bits o cardinalidad mientras se usa el cálculo de la fórmula, como y, o, xor, y no, etc.
-
-Hay 2 tipos de métodos de construcción para Bitmap Object. Uno debe ser construido por la función de agregación groupBitmap con -State , el otro debe ser construido por Array Object . También es para convertir objeto de mapa de bits a objeto de matriz.
-
-RoaringBitmap se envuelve en una estructura de datos, mientras que el almacenamiento real de los objetos de mapa de bits. Cuando la cardinalidad es menor o igual que 32, utiliza Set objet. Cuando la cardinalidad es mayor que 32, utiliza el objeto RoaringBitmap. Es por eso que el almacenamiento del conjunto de baja cardinalidad es más rápido.
-
-Para obtener más información sobre RoaringBitmap, consulte: [CRoaring](https://github.com/RoaringBitmap/CRoaring).

-# Funciones de comparación {#comparison-functions}
-
-Las funciones de comparación siempre devuelven 0 o 1 (Uint8).
-
-Se pueden comparar los siguientes tipos:
-
--   numero
--   cuerdas y cuerdas fijas
--   fechas
--   fechas con tiempos
-
-dentro de cada grupo, pero no entre diferentes grupos.
-
-Por ejemplo, no puede comparar una fecha con una cadena. Debe usar una función para convertir la cadena a una fecha, o viceversa.
-
-Las cadenas se comparan por bytes. Una cadena más corta es más pequeña que todas las cadenas que comienzan con ella y que contienen al menos un carácter más.

-# Funciones condicionales {#conditional-functions}
-
-## si {#if}
-
-Controla la bifurcación condicional. A diferencia de la mayoría de los sistemas, ClickHouse siempre evalúa ambas expresiones `then` y `else`.
-
-**Sintaxis**
-
-``` sql
-SELECT if(cond, then, else)
-```
-
-Si la condición `cond` evalúa a un valor distinto de cero, devuelve el resultado de la expresión `then` y el resultado de la expresión `else` si está presente, se omite. Si el `cond` es cero o `NULL` el resultado de la `then` expresión se omite y el resultado de la `else` expresión, si está presente, se devuelve.
-
-**Parámetros**
-
--   `cond` – The condition for evaluation that can be zero or not. The type is UInt8, Nullable(UInt8) or NULL.
--   `then` - La expresión que se va a devolver si se cumple la condición.
--   `else` - La expresión a devolver si no se cumple la condición.-
-
-**Valores devueltos**
-
-La función se ejecuta `then` y `else` expresiones y devuelve su resultado, dependiendo de si la condición `cond` terminó siendo cero o no.
-
-**Ejemplo**
-
-Consulta:
-
-``` sql
-SELECT if(1, plus(2, 2), plus(2, 6))
-```
-
-Resultado:
-
-``` text
-┌─plus(2, 2)─┐
-│          4 │
-└────────────┘
-```
-
-Consulta:
-
-``` sql
-SELECT if(0, plus(2, 2), plus(2, 6))
-```
-
-Resultado:
-
-``` text
-┌─plus(2, 6)─┐
-│          8 │
-└────────────┘
-```
-
--   `then` y `else` debe tener el tipo común más bajo.
-
-**Ejemplo:**
-
-Toma esto `LEFT_RIGHT` tabla:
-
-``` sql
-SELECT *
-FROM LEFT_RIGHT
-
-┌─left─┬─right─┐
-│ ᴺᵁᴸᴸ │     4 │
-│    1 │     3 │
-│    2 │     2 │
-│    3 │     1 │
-│    4 │  ᴺᵁᴸᴸ │
-└──────┴───────┘
-```
-
-La siguiente consulta compara `left` y `right` valor:
-
-``` sql
-SELECT
-    left,
-    right,
-    if(left < right, 'left is smaller than right', 'right is greater or equal than left') AS is_smaller
-FROM LEFT_RIGHT
-WHERE isNotNull(left) AND isNotNull(right)
-
-┌─left─┬─right─┬─is_smaller──────────────────────────┐
-│    1 │     3 │ left is smaller than right          │

-│    3 │     1 │ right is greater or equal than left │
-└──────┴───────┴─────────────────────────────────────┘
-```
-
-Nota: `NULL` los valores no se utilizan en este ejemplo, compruebe [Valores NULL en condicionales](#null-values-in-conditionals) apartado.
-
-## Operador ternario {#ternary-operator}
-
-Funciona igual que `if` función.
-
-Sintaxis: `cond ? then : else`
-
-Devoluciones `then` si el `cond` evalúa que es verdadero (mayor que cero), de lo contrario devuelve `else`.
-
--   `cond` debe ser de tipo de `UInt8`, y `then` y `else` debe tener el tipo común más bajo.
-
--   `then` y `else` puede ser `NULL`
-
-**Ver también**
-
--   [ifNotFinite](other-functions.md#ifnotfinite).
-
-## MultiIf {#multiif}
-
-Le permite escribir el [CASE](../operators/index.md#operator_case) operador más compacto en la consulta.
-
-Sintaxis: `multiIf(cond_1, then_1, cond_2, then_2, ..., else)`
-
-**Parámetros:**
-
--   `cond_N` — The condition for the function to return `then_N`.
--   `then_N` — The result of the function when executed.
--   `else` — The result of the function if none of the conditions is met.
-
-La función acepta `2N+1` parámetros.
-
-**Valores devueltos**
-
-La función devuelve uno de los valores `then_N` o `else` dependiendo de las condiciones `cond_N`.
-
-**Ejemplo**
-
-De nuevo usando `LEFT_RIGHT` tabla.
-
-``` sql
-SELECT
-    left,
-    right,
-    multiIf(left < right, 'left is smaller', left > right, 'left is greater', left = right, 'Both equal', 'Null value') AS result

-│    3 │     1 │ left is greater │
-│    4 │  ᴺᵁᴸᴸ │ Null value      │
-└──────┴───────┴─────────────────┘
-```
-
-## Uso directo de resultados condicionales {#using-conditional-results-directly}
-
-Los condicionales siempre dan como resultado `0`, `1` o `NULL`. Entonces puedes usar resultados condicionales directamente como este:
-
-``` sql
-SELECT left < right AS is_small
-FROM LEFT_RIGHT
-
-┌─is_small─┐

-└──────────┘
-```
-
-## Valores NULL en condicionales {#null-values-in-conditionals}
-
-Cuando `NULL` están involucrados en condicionales, el resultado también será `NULL`.
-
-``` sql
-SELECT
-    NULL < 1,

-
-Soporte para zonas horarias
-
-Todas las funciones para trabajar con la fecha y la hora que tienen un uso lógico para la zona horaria pueden aceptar un segundo argumento de zona horaria opcional. Ejemplo: Asia/Ekaterimburgo. En este caso, utilizan la zona horaria especificada en lugar de la local (predeterminada).
-
-``` sql
-SELECT
-    toDateTime('2016-06-15 23:00:00') AS time,
-    toDate(time) AS date_local,
-    toDate(time, 'Asia/Yekaterinburg') AS date_yekat,
-    toString(time, 'US/Samoa') AS time_samoa

-
-## ToWeek(fecha\[,modo\]) {#toweekdatemode}
-
-Esta función devuelve el número de semana para la fecha o la fecha y hora. La forma de dos argumentos de toWeek() le permite especificar si la semana comienza el domingo o el lunes y si el valor de retorno debe estar en el rango de 0 a 53 o de 1 a 53. Si se omite el argumento mode, el modo predeterminado es 0.
-`toISOWeek()`es una función de compatibilidad que es equivalente a `toWeek(date,3)`.
-La siguiente tabla describe cómo funciona el argumento mode.
-
-| Modo | Primer día de la semana | Gama | Week 1 is the first week … |
-|------|-------------------------|------|----------------------------|
-| 0    | Domingo                 | 0-53 | con un domingo de este año |
-| 1    | Lunes                   | 0-53 | con 4 o más días este año  |
-| 2    | Domingo                 | 1-53 | con un domingo de este año |
-| 3    | Lunes                   | 1-53 | con 4 o más días este año  |
-| 4    | Domingo                 | 0-53 | con 4 o más días este año  |
-| 5    | Lunes                   | 0-53 | con un lunes de este año   |
-| 6    | Domingo                 | 1-53 | con 4 o más días este año  |
-| 7    | Lunes                   | 1-53 | con un lunes de este año   |
-| 8    | Domingo                 | 1-53 | contiene 1 de enero        |
-| 9    | Lunes                   | 1-53 | contiene 1 de enero        |
-
-Para valores de modo con un significado de “with 4 or more days this year,” semanas están numeradas según ISO 8601:1988:
-
--   Si la semana que contiene el 1 de enero tiene 4 o más días en el nuevo año, es la semana 1.
-
--   De lo contrario, es la última semana del año anterior, y la semana siguiente es la semana 1.
-
-Para valores de modo con un significado de “contains January 1”, la semana contiene 1 de enero es la semana 1. No importa cuántos días en el nuevo año contenía la semana, incluso si contenía solo un día.

-
-## aYearWeek(fecha\[,modo\]) {#toyearweekdatemode}
-
-Devuelve año y semana para una fecha. El año en el resultado puede ser diferente del año en el argumento de fecha para la primera y la última semana del año.
-
-El argumento mode funciona exactamente igual que el argumento mode a toWeek() . Para la sintaxis de argumento único, se utiliza un valor de modo de 0.
-
-`toISOYear()`es una función de compatibilidad que es equivalente a `intDiv(toYearWeek(date,3),100)`.
-
-**Ejemplo**
-
-``` sql
-SELECT toDate('2016-12-27') AS date, toYearWeek(date) AS yearWeek0, toYearWeek(date,1) AS yearWeek1, toYearWeek(date,9) AS yearWeek9;

-Lo mismo que ‘today() - 1’.
-
-## timeSlot {#timeslot}
-
-Redondea el tiempo a la media hora.
-Esta función es específica de Yandex.Metrica, ya que media hora es la cantidad mínima de tiempo para dividir una sesión en dos sesiones si una etiqueta de seguimiento muestra las páginas vistas consecutivas de un solo usuario que difieren en el tiempo en estrictamente más de esta cantidad. Esto significa que las tuplas (el ID de etiqueta, el ID de usuario y el intervalo de tiempo) se pueden usar para buscar páginas vistas que se incluyen en la sesión correspondiente.

-# Funciones de codificación {#encoding-functions}
-
-## char {#char}
-
-Devuelve la cadena con la longitud como el número de argumentos pasados y cada byte tiene el valor del argumento correspondiente. Acepta varios argumentos de tipos numéricos. Si el valor del argumento está fuera del rango del tipo de datos UInt8, se convierte a UInt8 con posible redondeo y desbordamiento.
-
-**Sintaxis**
-
-``` sql
-char(number_1, [number_2, ..., number_n]);
-```
-
-**Parámetros**
-
--   `number_1, number_2, ..., number_n` — Numerical arguments interpreted as integers. Types: [En](../../sql-reference/data-types/int-uint.md), [Flotante](../../sql-reference/data-types/float.md).
-
-**Valor devuelto**
-
--   una cadena de bytes.
-
-Tipo: `String`.
-
-**Ejemplo**
-
-Consulta:
-
-``` sql
-SELECT char(104.1, 101, 108.9, 108.9, 111) AS hello
-```
-
-Resultado:
-
-``` text
-┌─hello─┐
-│ hello │
-└───────┘
-```
-
-Puede construir una cadena de codificación arbitraria pasando los bytes correspondientes. Aquí hay un ejemplo para UTF-8:
-
-Consulta:
-
-``` sql
-SELECT char(0xD0, 0xBF, 0xD1, 0x80, 0xD0, 0xB8, 0xD0, 0xB2, 0xD0, 0xB5, 0xD1, 0x82) AS hello;
-```
-
-Resultado:
-
-``` text
-┌─hello──┐
-│ привет │
-└────────┘
-```
-
-Consulta:
-
-``` sql
-SELECT char(0xE4, 0xBD, 0xA0, 0xE5, 0xA5, 0xBD) AS hello;
-```
-
-Resultado:
-
-``` text
-┌─hello─┐
-│ 你好  │
-└───────┘
-```
-
-## hexagonal {#hex}
-
-Devuelve una cadena que contiene la representación hexadecimal del argumento.
-
-**Sintaxis**
-
-``` sql
-hex(arg)
-```
-
-La función está usando letras mayúsculas `A-F` y no usar ningún prefijo (como `0x`) o sufijos (como `h`).
-
-Para argumentos enteros, imprime dígitos hexadecimales (“nibbles”) del más significativo al menos significativo (big endian o “human readable” orden). Comienza con el byte distinto de cero más significativo (se omiten los cero bytes principales) pero siempre imprime ambos dígitos de cada byte incluso si el dígito inicial es cero.
-
-Ejemplo:
-
-**Ejemplo**
-
-Consulta:
-
-``` sql
-SELECT hex(1);
-```
-
-Resultado:
-
-``` text
-01
-```
-
-Valores de tipo `Date` y `DateTime` están formateados como enteros correspondientes (el número de días desde Epoch para Date y el valor de Unix Timestamp para DateTime).
-
-Para `String` y `FixedString`, todos los bytes son simplemente codificados como dos números hexadecimales. No se omiten cero bytes.
-
-Los valores de los tipos de coma flotante y Decimal se codifican como su representación en la memoria. Como apoyamos la pequeña arquitectura endian, están codificados en little endian. No se omiten cero bytes iniciales / finales.
-
-**Parámetros**
-
--   `arg` — A value to convert to hexadecimal. Types: [Cadena](../../sql-reference/data-types/string.md), [UInt](../../sql-reference/data-types/int-uint.md), [Flotante](../../sql-reference/data-types/float.md), [Decimal](../../sql-reference/data-types/decimal.md), [Fecha](../../sql-reference/data-types/date.md) o [FechaHora](../../sql-reference/data-types/datetime.md).
-
-**Valor devuelto**

-│ 0000000000003040 │
-└──────────────────┘
-```
-
-## unhex(str) {#unhexstr}
-
-Acepta una cadena que contiene cualquier número de dígitos hexadecimales y devuelve una cadena que contiene los bytes correspondientes. Admite letras mayúsculas y minúsculas A-F. El número de dígitos hexadecimales no tiene que ser par. Si es impar, el último dígito se interpreta como la mitad menos significativa del byte 00-0F. Si la cadena de argumento contiene algo que no sean dígitos hexadecimales, se devuelve algún resultado definido por la implementación (no se produce una excepción).
-Si desea convertir el resultado en un número, puede usar el ‘reverse’ y ‘reinterpretAsType’ función.
-
-## UUIDStringToNum (str) {#uuidstringtonumstr}
-
-Acepta una cadena que contiene 36 caracteres en el formato `123e4567-e89b-12d3-a456-426655440000`, y lo devuelve como un conjunto de bytes en un FixedString(16).
-
-## UUIDNumToString (str) {#uuidnumtostringstr}
-
-Acepta un valor de FixedString(16). Devuelve una cadena que contiene 36 caracteres en formato de texto.
-
-## ¿Cómo puedo hacerlo?) {#bitmasktolistnum}
-
-Acepta un entero. Devuelve una cadena que contiene la lista de potencias de dos que suman el número de origen cuando se suma. Están separados por comas sin espacios en formato de texto, en orden ascendente.
-
-## ¿Qué puedes encontrar en Neodigit) {#bitmasktoarraynum}
-
-Acepta un entero. Devuelve una matriz de números UInt64 que contiene la lista de potencias de dos que suman el número de origen cuando se suma. Los números en la matriz están en orden ascendente.

-## MD5 {#hash_functions-md5}
-
-Calcula el MD5 de una cadena y devuelve el conjunto de bytes resultante como FixedString(16).
-Si no necesita MD5 en particular, pero necesita un hash criptográfico decente de 128 bits, use el ‘sipHash128’ función en su lugar.
-Si desea obtener el mismo resultado que la salida de la utilidad md5sum, use lower(hex(MD5(s)) .
-
-## sipHash64 {#hash_functions-siphash64}
-
-Produce un [SipHash](https://131002.net/siphash/) valor hash.
-

-
-Esta es una función hash criptográfica. Funciona al menos tres veces más rápido que el [MD5](#hash_functions-md5) función.
-
-Función [interpretar](../../sql-reference/functions/type-conversion-functions.md#type_conversion_functions-reinterpretAsString) todos los parámetros de entrada como cadenas y calcula el valor hash para cada uno de ellos. Luego combina hashes por el siguiente algoritmo:
-
-1.  Después de hash todos los parámetros de entrada, la función obtiene la matriz de hashes.
-2.  La función toma el primero y el segundo elementos y calcula un hash para la matriz de ellos.
-3.  Luego, la función toma el valor hash, calculado en el paso anterior, y el tercer elemento de la matriz hash inicial, y calcula un hash para la matriz de ellos.
-4.  El paso anterior se repite para todos los elementos restantes de la matriz hash inicial.

-A [UInt64](../../sql-reference/data-types/int-uint.md) tipo de datos valor hash.
-
-**Ejemplos**
-
-Ejemplo de llamada:
-
-``` sql
-SELECT cityHash64(array('e','x','a'), 'mple', 10, toDateTime('2019-06-15 23:00:00')) AS CityHash, toTypeName(CityHash) AS type
-```
-
-``` text
-┌─────────────CityHash─┬─type───┐
-│ 12072650598913549138 │ UInt64 │
-└──────────────────────┴────────┘
-```
-
-En el ejemplo siguiente se muestra cómo calcular la suma de comprobación de toda la tabla con precisión hasta el orden de fila:
-
-``` sql
-SELECT groupBitXor(cityHash64(*)) FROM table
-```
-
-## intHash32 {#inthash32}
-
-Calcula un código hash de 32 bits a partir de cualquier tipo de entero.
-Esta es una función hash no criptográfica relativamente rápida de calidad media para los números.
-
-## intHash64 {#inthash64}
-
-Calcula un código hash de 64 bits a partir de cualquier tipo de entero.
-Funciona más rápido que intHash32. Calidad media.
-
-## SHA1 {#sha1}
-
-## SHA224 {#sha224}
-
-## SHA256 {#sha256}
-
-Calcula SHA-1, SHA-224 o SHA-256 de una cadena y devuelve el conjunto de bytes resultante como FixedString(20), FixedString(28) o FixedString(32).
-La función funciona bastante lentamente (SHA-1 procesa alrededor de 5 millones de cadenas cortas por segundo por núcleo del procesador, mientras que SHA-224 y SHA-256 procesan alrededor de 2.2 millones).
-Recomendamos usar esta función solo en los casos en que necesite una función hash específica y no pueda seleccionarla.
-Incluso en estos casos, recomendamos aplicar la función offline y precalcular valores al insertarlos en la tabla, en lugar de aplicarlo en SELECTS.
-
-## Nombre de la red inalámbrica (SSID):\]) {#urlhashurl-n}
-
-Una función hash no criptográfica rápida y de calidad decente para una cadena obtenida de una URL utilizando algún tipo de normalización.
-`URLHash(s)` – Calculates a hash from a string without one of the trailing symbols `/`,`?` o `#` al final, si está presente.
-`URLHash(s, N)` – Calculates a hash from a string up to the N level in the URL hierarchy, without one of the trailing symbols `/`,`?` o `#` al final, si está presente.
-Los niveles son los mismos que en URLHierarchy. Esta función es específica de Yandex.Métrica.

-# Funciones de orden superior {#higher-order-functions}
-
-## `->` operador, función lambda (params, expr) {#operator-lambdaparams-expr-function}
-
-Allows describing a lambda function for passing to a higher-order function. The left side of the arrow has a formal parameter, which is any ID, or multiple formal parameters – any IDs in a tuple. The right side of the arrow has an expression that can use these formal parameters, as well as any table columns.
-
-Ejemplos: `x -> 2 * x, str -> str != Referer.`
-
-Las funciones de orden superior solo pueden aceptar funciones lambda como su argumento funcional.
-
-Una función lambda que acepta múltiples argumentos se puede pasar a una función de orden superior. En este caso, a la función de orden superior se le pasan varias matrices de idéntica longitud a las que corresponderán estos argumentos.
-
-Para algunas funciones, tales como [arrayCount](#higher_order_functions-array-count) o [arraySum](#higher_order_functions-array-count), el primer argumento (la función lambda) se puede omitir. En este caso, se supone un mapeo idéntico.
-
-No se puede omitir una función lambda para las siguientes funciones:
-
--   [arrayMap](#higher_order_functions-array-map)
--   [arrayFilter](#higher_order_functions-array-filter)
--   [arrayFill](#higher_order_functions-array-fill)
--   [arrayReverseFill](#higher_order_functions-array-reverse-fill)
--   [arraySplit](#higher_order_functions-array-split)
--   [arrayReverseSplit](#higher_order_functions-array-reverse-split)
--   [arrayFirst](#higher_order_functions-array-first)
--   [arrayFirstIndex](#higher_order_functions-array-first-index)
-
-### arrayMap(func, arr1, …) {#higher_order_functions-array-map}
-
-Devuelve una matriz obtenida de la aplicación original `func` función a cada elemento en el `arr` matriz.
-
-Ejemplos:
-
-``` sql
-SELECT arrayMap(x -> (x + 2), [1, 2, 3]) as res;
-```
-
-``` text
-┌─res─────┐
-│ [3,4,5] │
-└─────────┘
-```
-
-En el ejemplo siguiente se muestra cómo crear una tupla de elementos de diferentes matrices:
-
-``` sql
-SELECT arrayMap((x, y) -> (x, y), [1, 2, 3], [4, 5, 6]) AS res
-```
-
-``` text
-┌─res─────────────────┐
-│ [(1,4),(2,5),(3,6)] │
-└─────────────────────┘
-```
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arrayMap` función.
-
-### arrayFilter(func, arr1, …) {#higher_order_functions-array-filter}
-
-Devuelve una matriz que contiene sólo los elementos en `arr1` para los cuales `func` devuelve algo distinto de 0.
-
-Ejemplos:
-
-``` sql
-SELECT arrayFilter(x -> x LIKE '%World%', ['Hello', 'abc World']) AS res
-```
-
-``` text
-┌─res───────────┐
-│ ['abc World'] │
-└───────────────┘
-```
-
-``` sql
-SELECT
-    arrayFilter(
-        (i, x) -> x LIKE '%World%',
-        arrayEnumerate(arr),
-        ['Hello', 'abc World'] AS arr)
-    AS res
-```
-
-``` text
-┌─res─┐
-│ [2] │
-└─────┘
-```
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arrayFilter` función.
-
-### arrayFill(func, arr1, …) {#higher_order_functions-array-fill}
-
-Escanear a través de `arr1` desde el primer elemento hasta el último elemento y reemplazar `arr1[i]` por `arr1[i - 1]` si `func` devuelve 0. El primer elemento de `arr1` no será reemplazado.
-
-Ejemplos:
-
-``` sql
-SELECT arrayFill(x -> not isNull(x), [1, null, 3, 11, 12, null, null, 5, 6, 14, null, null]) AS res
-```
-
-``` text
-┌─res──────────────────────────────┐
-│ [1,1,3,11,12,12,12,5,6,14,14,14] │
-└──────────────────────────────────┘

-
-### arrayReverseFill(func, arr1, …) {#higher_order_functions-array-reverse-fill}
-
-Escanear a través de `arr1` del último elemento al primer elemento y reemplace `arr1[i]` por `arr1[i + 1]` si `func` devuelve 0. El último elemento de `arr1` no será reemplazado.
-
-Ejemplos:
-
-``` sql
-SELECT arrayReverseFill(x -> not isNull(x), [1, null, 3, 11, 12, null, null, 5, 6, 14, null, null]) AS res
-```
-
-``` text
-┌─res────────────────────────────────┐
-│ [1,3,3,11,12,5,5,5,6,14,NULL,NULL] │
-└────────────────────────────────────┘
-```
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arrayReverseFill` función.
-
-### arraySplit(func, arr1, …) {#higher_order_functions-array-split}
-
-Dividir `arr1` en múltiples matrices. Cuando `func` devuelve algo distinto de 0, la matriz se dividirá en el lado izquierdo del elemento. La matriz no se dividirá antes del primer elemento.
-
-Ejemplos:
-
-``` sql
-SELECT arraySplit((x, y) -> y, [1, 2, 3, 4, 5], [1, 0, 0, 1, 0]) AS res
-```
-
-``` text
-┌─res─────────────┐
-│ [[1,2,3],[4,5]] │
-└─────────────────┘
-```
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arraySplit` función.
-
-### arrayReverseSplit(func, arr1, …) {#higher_order_functions-array-reverse-split}
-
-Dividir `arr1` en múltiples matrices. Cuando `func` devuelve algo distinto de 0, la matriz se dividirá en el lado derecho del elemento. La matriz no se dividirá después del último elemento.
-
-Ejemplos:
-
-``` sql
-SELECT arrayReverseSplit((x, y) -> y, [1, 2, 3, 4, 5], [1, 0, 0, 1, 0]) AS res
-```
-
-``` text
-┌─res───────────────┐
-│ [[1],[2,3,4],[5]] │
-└───────────────────┘
-```
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arraySplit` función.
-
-### arrayCount(\[func,\] arr1, …) {#higher_order_functions-array-count}
-
-Devuelve el número de elementos de la matriz arr para los cuales func devuelve algo distinto de 0. Si ‘func’ no se especifica, devuelve el número de elementos distintos de cero en la matriz.
-
-### arrayExists(\[func,\] arr1, …) {#arrayexistsfunc-arr1}
-
-Devuelve 1 si hay al menos un elemento en ‘arr’ para los cuales ‘func’ devuelve algo distinto de 0. De lo contrario, devuelve 0.
-
-### arrayAll(\[func,\] arr1, …) {#arrayallfunc-arr1}
-
-Devuelve 1 si ‘func’ devuelve algo distinto de 0 para todos los elementos en ‘arr’. De lo contrario, devuelve 0.
-
-### arraySum(\[func,\] arr1, …) {#higher-order-functions-array-sum}
-
-Devuelve la suma de la ‘func’ valor. Si se omite la función, simplemente devuelve la suma de los elementos de la matriz.
-
-### arrayFirst(func, arr1, …) {#higher_order_functions-array-first}
-
-Devuelve el primer elemento en el ‘arr1’ matriz para la cual ‘func’ devuelve algo distinto de 0.
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arrayFirst` función.
-
-### arrayFirstIndex(func, arr1, …) {#higher_order_functions-array-first-index}
-
-Devuelve el índice del primer elemento ‘arr1’ matriz para la cual ‘func’ devuelve algo distinto de 0.
-
-Tenga en cuenta que el primer argumento (función lambda) no se puede omitir en el `arrayFirstIndex` función.
-
-### arrayCumSum(\[func,\] arr1, …) {#arraycumsumfunc-arr1}
-
-Devuelve una matriz de sumas parciales de elementos en la matriz de origen (una suma en ejecución). Si el `func` se especifica la función, luego los valores de los elementos de la matriz se convierten mediante esta función antes de sumar.
-
-Ejemplo:
-
-``` sql
-SELECT arrayCumSum([1, 1, 1, 1]) AS res
-```
-
-``` text
-┌─res──────────┐
-│ [1, 2, 3, 4] │
-└──────────────┘
-```
-
-### Información de archivo) {#arraycumsumnonnegativearr}
-
-Lo mismo que `arrayCumSum`, devuelve una matriz de sumas parciales de elementos en la matriz de origen (una suma en ejecución). Diferente `arrayCumSum`, cuando el valor devuelto contiene un valor menor que cero, el valor se reemplaza con cero y el cálculo posterior se realiza con cero parámetros. Por ejemplo:
-
-``` sql
-SELECT arrayCumSumNonNegative([1, 1, -4, 1]) AS res
-```
-
-``` text
-┌─res───────┐
-│ [1,2,0,1] │
-└───────────┘
-```
-
-### arraySort(\[func,\] arr1, …) {#arraysortfunc-arr1}
-
-Devuelve una matriz como resultado de ordenar los elementos de `arr1` en orden ascendente. Si el `func` se especifica la función, el orden de clasificación se determina por el resultado de la función `func` aplicado a los elementos de la matriz (arrays)
-
-El [Transformación de Schwartzian](https://en.wikipedia.org/wiki/Schwartzian_transform) se utiliza para mejorar la eficiencia de clasificación.
-
-Ejemplo:
-
-``` sql
-SELECT arraySort((x, y) -> y, ['hello', 'world'], [2, 1]);
-```
-
-``` text
-┌─res────────────────┐
-│ ['world', 'hello'] │
-└────────────────────┘
-```
-
-Para obtener más información sobre el `arraySort` método, véase el [Funciones para trabajar con matrices](array-functions.md#array_functions-sort) apartado.
-
-### arrayReverseSort(\[func,\] arr1, …) {#arrayreversesortfunc-arr1}
-
-Devuelve una matriz como resultado de ordenar los elementos de `arr1` en orden descendente. Si el `func` se especifica la función, el orden de clasificación se determina por el resultado de la función `func` aplicado a los elementos de la matriz (arrays).
-
-Ejemplo:
-
-``` sql
-SELECT arrayReverseSort((x, y) -> y, ['hello', 'world'], [2, 1]) as res;
-```
-
-``` text
-┌─res───────────────┐
-│ ['hello','world'] │
-└───────────────────┘
-```
-
-Para obtener más información sobre el `arrayReverseSort` método, véase el [Funciones para trabajar con matrices](array-functions.md#array_functions-reverse-sort) apartado.

-# Funciones para implementar el operador IN {#functions-for-implementing-the-in-operator}
-
-## Información de uso {#in-functions}
-
-Vea la sección [IN operadores](../operators/in.md#select-in-operators).
-
-## tuple(x, y, …), operator (x, y, …) {#tuplex-y-operator-x-y}
-
-Una función que permite agrupar varias columnas.
-For columns with the types T1, T2, …, it returns a Tuple(T1, T2, …) type tuple containing these columns. There is no cost to execute the function.
-Las tuplas se usan normalmente como valores intermedios para un argumento de operadores IN, o para crear una lista de parámetros formales de funciones lambda. Las tuplas no se pueden escribir en una tabla.
-
-## Puede utilizar el siguiente ejemplo: {#tupleelementtuple-n-operator-x-n}
-
-Una función que permite obtener una columna de una tupla.
-‘N’ es el índice de columna, comenzando desde 1. N debe ser una constante. ‘N’ debe ser una constante. ‘N’ debe ser un entero postivo estricto no mayor que el tamaño de la tupla.
-No hay ningún costo para ejecutar la función.

-# Función {#functions}
-
-Hay al menos \* dos tipos de funciones: funciones regulares (simplemente se llaman “functions”) and aggregate functions. These are completely different concepts. Regular functions work as if they are applied to each row separately (for each row, the result of the function doesn't depend on the other rows). Aggregate functions accumulate a set of values from various rows (i.e. they depend on the entire set of rows).
-
-En esta sección discutimos las funciones regulares. Para las funciones agregadas, consulte la sección “Aggregate functions”.
-
-\* - Existe un tercer tipo de función que el ‘arrayJoin’ la función pertenece a; las funciones de la tabla también se pueden mencionar por separado.\*
-
-## Fuerte mecanografía {#strong-typing}
-
-A diferencia del SQL estándar, ClickHouse tiene una tipificación fuerte. En otras palabras, no hace conversiones implícitas entre tipos. Cada función funciona para un conjunto específico de tipos. Esto significa que a veces necesita usar funciones de conversión de tipos.
-
-## Eliminación de subexpresiones comunes {#common-subexpression-elimination}
-
-Se considera que todas las expresiones de una consulta que tienen el mismo AST (el mismo registro o el mismo resultado del análisis sintáctico) tienen valores idénticos. Tales expresiones se concatenan y se ejecutan una vez. Las subconsultas idénticas también se eliminan de esta manera.
-
-## Tipos de resultados {#types-of-results}
-
-Todas las funciones devuelven un único retorno como resultado (no varios valores, y no valores cero). El tipo de resultado generalmente se define solo por los tipos de argumentos, no por los valores. Las excepciones son la función tupleElement (el operador a.N) y la función toFixedString.
-
-## Constante {#constants}
-
-Para simplificar, ciertas funciones solo pueden funcionar con constantes para algunos argumentos. Por ejemplo, el argumento correcto del operador LIKE debe ser una constante.
-Casi todas las funciones devuelven una constante para argumentos constantes. La excepción son las funciones que generan números aleatorios.
-El ‘now’ function devuelve valores diferentes para las consultas que se ejecutaron en diferentes momentos, pero el resultado se considera una constante, ya que la constancia solo es importante dentro de una sola consulta.
-Una expresión constante también se considera una constante (por ejemplo, la mitad derecha del operador LIKE se puede construir a partir de múltiples constantes).
-
-Las funciones se pueden implementar de diferentes maneras para argumentos constantes y no constantes (se ejecuta un código diferente). Pero los resultados para una constante y para una columna verdadera que contiene solo el mismo valor deben coincidir entre sí.
-
-## Procesamiento NULL {#null-processing}
-
-Las funciones tienen los siguientes comportamientos:
-
--   Si al menos uno de los argumentos de la función es `NULL` el resultado de la función es también `NULL`.
--   Comportamiento especial que se especifica individualmente en la descripción de cada función. En el código fuente de ClickHouse, estas funciones tienen `UseDefaultImplementationForNulls=false`.
-
-## Constancia {#constancy}
-
-Functions can't change the values of their arguments – any changes are returned as the result. Thus, the result of calculating separate functions does not depend on the order in which the functions are written in the query.
-
-## Manejo de errores {#error-handling}
-
-Algunas funciones pueden producir una excepción si los datos no son válidos. En este caso, la consulta se cancela y se devuelve un texto de error al cliente. Para el procesamiento distribuido, cuando se produce una excepción en uno de los servidores, los otros servidores también intentan anular la consulta.
-
-## Evaluación de las expresiones de argumento {#evaluation-of-argument-expressions}
-
-En casi todos los lenguajes de programación, uno de los argumentos puede no evaluarse para ciertos operadores. Esto suele ser los operadores `&&`, `||`, y `?:`.
-Pero en ClickHouse, los argumentos de las funciones (operadores) siempre se evalúan. Esto se debe a que partes enteras de columnas se evalúan a la vez, en lugar de calcular cada fila por separado.
-
-## Realización de funciones para el procesamiento de consultas distribuidas {#performing-functions-for-distributed-query-processing}
-
-Para el procesamiento de consultas distribuidas, se realizan tantas etapas de procesamiento de consultas como sea posible en servidores remotos, y el resto de las etapas (fusionando resultados intermedios y todo lo posterior) se realizan en el servidor solicitante.
-
-Esto significa que las funciones se pueden realizar en diferentes servidores.
-Por ejemplo, en la consulta `SELECT f(sum(g(x))) FROM distributed_table GROUP BY h(y),`
-
--   si una `distributed_table` tiene al menos dos fragmentos, las funciones ‘g’ y ‘h’ se realizan en servidores remotos, y la función ‘f’ se realiza en el servidor solicitante.
--   si una `distributed_table` tiene sólo un fragmento, todos los ‘f’, ‘g’, y ‘h’ funciones se realizan en el servidor de este fragmento.
-
-El resultado de una función generalmente no depende del servidor en el que se realice. Sin embargo, a veces esto es importante.
-Por ejemplo, las funciones que funcionan con diccionarios utilizan el diccionario que existe en el servidor en el que se están ejecutando.
-Otro ejemplo es el `hostName` función, que devuelve el nombre del servidor en el que se está ejecutando para `GROUP BY` por servidores en un `SELECT` consulta.
-
-Si se realiza una función en una consulta en el servidor solicitante, pero debe realizarla en servidores remotos, puede envolverla en un ‘any’ agregar o agregarlo a una clave en `GROUP BY`.

-# Funciones de introspección {#introspection-functions}
-
-Puede utilizar las funciones descritas en este capítulo para [ELF](https://en.wikipedia.org/wiki/Executable_and_Linkable_Format) y [DWARF](https://en.wikipedia.org/wiki/DWARF) para la creación de perfiles de consultas.
-
-!!! warning "Advertencia"
-    Estas funciones son lentas y pueden imponer consideraciones de seguridad.
-
-Para el correcto funcionamiento de las funciones de introspección:
-
--   Instale el `clickhouse-common-static-dbg` paquete.
-
--   Establezca el [allow_introspection_functions](../../operations/settings/settings.md#settings-allow_introspection_functions) a 1.
-
-        For security reasons introspection functions are disabled by default.
-
-ClickHouse guarda los informes del generador de perfiles [trace_log](../../operations/system-tables.md#system_tables-trace_log) tabla del sistema. Asegúrese de que la tabla y el generador de perfiles estén configurados correctamente.
-
-## addressToLine {#addresstoline}

----
-
-# Funciones para trabajar con JSON {#functions-for-working-with-json}
-
-En el Yandex.Metrica, JSON es transmitido por los usuarios como parámetros de sesión. Hay algunas funciones especiales para trabajar con este JSON. (Aunque en la mayoría de los casos, los JSON también se procesan previamente, y los valores resultantes se colocan en columnas separadas en su formato procesado.) Todas estas funciones se basan en sólidas suposiciones sobre lo que puede ser el JSON, pero tratan de hacer lo menos posible para hacer el trabajo.
-
-Se hacen las siguientes suposiciones:
-
-1.  El nombre de campo (argumento de función) debe ser una constante.
-2.  El nombre del campo de alguna manera está codificado canónicamente en JSON. Por ejemplo: `visitParamHas('{"abc":"def"}', 'abc') = 1`, pero `visitParamHas('{"\\u0061\\u0062\\u0063":"def"}', 'abc') = 0`
-3.  Los campos se buscan en cualquier nivel de anidación, indiscriminadamente. Si hay varios campos coincidentes, se utiliza la primera aparición.
-4.  El JSON no tiene caracteres de espacio fuera de los literales de cadena.
-
-## visitParamHas (params, nombre) {#visitparamhasparams-name}
-
-Comprueba si hay un campo con el ‘name’ nombre.
-
-## visitParamExtractUInt (params, nombre) {#visitparamextractuintparams-name}
-
-Analiza UInt64 a partir del valor del campo denominado ‘name’. Si se trata de un campo de cadena, intenta analizar un número desde el principio de la cadena. Si el campo no existe, o existe pero no contiene un número, devuelve 0.
-
-## visitParamExtractInt (params, nombre) {#visitparamextractintparams-name}
-
-Lo mismo que para Int64.
-
-## visitParamExtractFloat (params, nombre) {#visitparamextractfloatparams-name}
-
-Lo mismo que para Float64.
-
-## visitParamExtractBool (params, nombre) {#visitparamextractboolparams-name}
-
-Analiza un valor verdadero/falso. El resultado es UInt8.
-
-## visitParamExtractRaw (params, nombre) {#visitparamextractrawparams-name}
-
-Devuelve el valor de un campo, incluidos los separadores.
-
-Ejemplos:
-
-``` sql
-visitParamExtractRaw('{"abc":"\\n\\u0000"}', 'abc') = '"\\n\\u0000"'
-visitParamExtractRaw('{"abc":{"def":[1,2,3]}}', 'abc') = '{"def":[1,2,3]}'
-```
-
-## visitParamExtractString(params, nombre) {#visitparamextractstringparams-name}
-
-Analiza la cadena entre comillas dobles. El valor es sin escape. Si no se pudo desescapar, devuelve una cadena vacía.
-
-Ejemplos:
-
-``` sql
-visitParamExtractString('{"abc":"\\n\\u0000"}', 'abc') = '\n\0'
-visitParamExtractString('{"abc":"\\u263a"}', 'abc') = '☺'
-visitParamExtractString('{"abc":"\\u263"}', 'abc') = ''
-visitParamExtractString('{"abc":"hello}', 'abc') = ''
-```
-
-Actualmente no hay soporte para puntos de código en el formato `\uXXXX\uYYYY` que no son del plano multilingüe básico (se convierten a CESU-8 en lugar de UTF-8).
-
-Las siguientes funciones se basan en [simdjson](https://github.com/lemire/simdjson) diseñado para requisitos de análisis JSON más complejos. La suposición 2 mencionada anteriormente todavía se aplica.
-
-## ¿Qué puedes encontrar en Neodigit) {#isvalidjsonjson}
-
-Comprueba que la cadena pasada es un json válido.
-
-Ejemplos:
-
-``` sql
-SELECT isValidJSON('{"a": "hello", "b": [-100, 200.0, 300]}') = 1
-SELECT isValidJSON('not a json') = 0
-```
-
-## JSONHas(json\[, indices_or_keys\]…) {#jsonhasjson-indices-or-keys}
-
-Si el valor existe en el documento JSON, `1` serán devueltos.
-
-Si el valor no existe, `0` serán devueltos.
-
-Ejemplos:
-
-``` sql
-SELECT JSONHas('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = 1
-SELECT JSONHas('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 4) = 0
-```
-
-`indices_or_keys` es una lista de cero o más argumentos, cada uno de ellos puede ser de cadena o entero.
-
--   Cadena = miembro del objeto de acceso por clave.
--   Entero positivo = acceder al n-ésimo miembro / clave desde el principio.
--   Entero negativo = acceder al n-ésimo miembro / clave desde el final.
-
-El índice mínimo del elemento es 1. Por lo tanto, el elemento 0 no existe.
-
-Puede usar enteros para acceder a matrices JSON y objetos JSON.
-
-Entonces, por ejemplo:
-
-``` sql
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', 1) = 'a'
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', 2) = 'b'
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', -1) = 'b'
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', -2) = 'a'
-SELECT JSONExtractString('{"a": "hello", "b": [-100, 200.0, 300]}', 1) = 'hello'
-```
-
-## JSONLength(json\[, indices_or_keys\]…) {#jsonlengthjson-indices-or-keys}
-
-Devuelve la longitud de una matriz JSON o un objeto JSON.
-
-Si el valor no existe o tiene un tipo incorrecto, `0` serán devueltos.
-
-Ejemplos:
-
-``` sql
-SELECT JSONLength('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = 3
-SELECT JSONLength('{"a": "hello", "b": [-100, 200.0, 300]}') = 2
-```
-
-## JSONType(json\[, indices_or_keys\]…) {#jsontypejson-indices-or-keys}
-
-Devuelve el tipo de un valor JSON.
-
-Si el valor no existe, `Null` serán devueltos.
-
-Ejemplos:
-
-``` sql
-SELECT JSONType('{"a": "hello", "b": [-100, 200.0, 300]}') = 'Object'
-SELECT JSONType('{"a": "hello", "b": [-100, 200.0, 300]}', 'a') = 'String'
-SELECT JSONType('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = 'Array'
-```
-
-## JSONExtractUInt(json\[, indices_or_keys\]…) {#jsonextractuintjson-indices-or-keys}
-
-## JSONExtractInt(json\[, indices_or_keys\]…) {#jsonextractintjson-indices-or-keys}
-
-## JSONExtractFloat(json\[, indices_or_keys\]…) {#jsonextractfloatjson-indices-or-keys}
-
-## JSONExtractBool(json\[, indices_or_keys\]…) {#jsonextractbooljson-indices-or-keys}
-
-Analiza un JSON y extrae un valor. Estas funciones son similares a `visitParam` función.
-
-Si el valor no existe o tiene un tipo incorrecto, `0` serán devueltos.
-
-Ejemplos:
-
-``` sql
-SELECT JSONExtractInt('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 1) = -100
-SELECT JSONExtractFloat('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 2) = 200.0
-SELECT JSONExtractUInt('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', -1) = 300
-```
-
-## JSONExtractString(json\[, indices_or_keys\]…) {#jsonextractstringjson-indices-or-keys}
-
-Analiza un JSON y extrae una cadena. Esta función es similar a `visitParamExtractString` función.
-
-Si el valor no existe o tiene un tipo incorrecto, se devolverá una cadena vacía.
-
-El valor es sin escape. Si no se pudo desescapar, devuelve una cadena vacía.
-
-Ejemplos:
-
-``` sql
-SELECT JSONExtractString('{"a": "hello", "b": [-100, 200.0, 300]}', 'a') = 'hello'
-SELECT JSONExtractString('{"abc":"\\n\\u0000"}', 'abc') = '\n\0'
-SELECT JSONExtractString('{"abc":"\\u263a"}', 'abc') = '☺'
-SELECT JSONExtractString('{"abc":"\\u263"}', 'abc') = ''
-SELECT JSONExtractString('{"abc":"hello}', 'abc') = ''
-```
-
-## JSONExtract(json\[, indices_or_keys…\], Return_type) {#jsonextractjson-indices-or-keys-return-type}
-
-Analiza un JSON y extrae un valor del tipo de datos ClickHouse dado.
-
-Esta es una generalización de la anterior `JSONExtract<type>` función.
-Esto significa
-`JSONExtract(..., 'String')` devuelve exactamente lo mismo que `JSONExtractString()`,
-`JSONExtract(..., 'Float64')` devuelve exactamente lo mismo que `JSONExtractFloat()`.
-
-Ejemplos:
-
-``` sql
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'Tuple(String, Array(Float64))') = ('hello',[-100,200,300])
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'Tuple(b Array(Float64), a String)') = ([-100,200,300],'hello')
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 'Array(Nullable(Int8))') = [-100, NULL, NULL]
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 4, 'Nullable(Int64)') = NULL
-SELECT JSONExtract('{"passed": true}', 'passed', 'UInt8') = 1
-SELECT JSONExtract('{"day": "Thursday"}', 'day', 'Enum8(\'Sunday\' = 0, \'Monday\' = 1, \'Tuesday\' = 2, \'Wednesday\' = 3, \'Thursday\' = 4, \'Friday\' = 5, \'Saturday\' = 6)') = 'Thursday'
-SELECT JSONExtract('{"day": 5}', 'day', 'Enum8(\'Sunday\' = 0, \'Monday\' = 1, \'Tuesday\' = 2, \'Wednesday\' = 3, \'Thursday\' = 4, \'Friday\' = 5, \'Saturday\' = 6)') = 'Friday'
-```
-
-## JSONExtractKeysAndValues(json\[, indices_or_keys…\], Value_type) {#jsonextractkeysandvaluesjson-indices-or-keys-value-type}
-
-Analiza los pares clave-valor de un JSON donde los valores son del tipo de datos ClickHouse especificado.
-
-Ejemplo:
-
-``` sql
-SELECT JSONExtractKeysAndValues('{"x": {"a": 5, "b": 7, "c": 11}}', 'x', 'Int8') = [('a',5),('b',7),('c',11)]
-```
-
-## JSONExtractRaw(json\[, indices_or_keys\]…) {#jsonextractrawjson-indices-or-keys}
-
-Devuelve una parte de JSON como cadena sin analizar.
-
-Si la pieza no existe o tiene un tipo incorrecto, se devolverá una cadena vacía.
-
-Ejemplo:
-
-``` sql
-SELECT JSONExtractRaw('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = '[-100, 200.0, 300]'
-```
-
-## JSONExtractArrayRaw(json\[, indices_or_keys…\]) {#jsonextractarrayrawjson-indices-or-keys}
-
-Devuelve una matriz con elementos de matriz JSON, cada uno representado como cadena sin analizar.
-
-Si la parte no existe o no es una matriz, se devolverá una matriz vacía.
-
-Ejemplo:
-
-``` sql
-SELECT JSONExtractArrayRaw('{"a": "hello", "b": [-100, 200.0, "hello"]}', 'b') = ['-100', '200.0', '"hello"']'
-```
-
-## JSONExtractKeysAndValuesRaw {#json-extract-keys-and-values-raw}
-
-Extrae datos sin procesar de un objeto JSON.
-
-**Sintaxis**
-
-``` sql
-JSONExtractKeysAndValuesRaw(json[, p, a, t, h])
-```
-
-**Parámetros**
-
--   `json` — [Cadena](../data-types/string.md) con JSON válido.
--   `p, a, t, h` — Comma-separated indices or keys that specify the path to the inner field in a nested JSON object. Each argument can be either a [cadena](../data-types/string.md) para obtener el campo por la clave o un [entero](../data-types/int-uint.md) para obtener el campo N-ésimo (indexado desde 1, los enteros negativos cuentan desde el final). Si no se establece, todo el JSON se analiza como el objeto de nivel superior. Parámetro opcional.
-
-**Valores devueltos**
-
--   Matriz con `('key', 'value')` tuplas. Ambos miembros de tupla son cadenas.
--   Vacíe la matriz si el objeto solicitado no existe o si la entrada JSON no es válida.
-
-Tipo: [Matriz](../data-types/array.md)([Tupla](../data-types/tuple.md)([Cadena](../data-types/string.md), [Cadena](../data-types/string.md)).

-
-## isConstant {#is-constant}
-
-Comprueba si el argumento es una expresión constante.
-
-A constant expression means an expression whose resulting value is known at the query analysis (i.e. before execution). For example, expressions over [literal](../syntax.md#literals) son expresiones constantes.
-
-La función está destinada al desarrollo, depuración y demostración.
-

-## transformar {#transform}
-
-Transforma un valor de acuerdo con la asignación explícitamente definida de algunos elementos a otros.
-Hay dos variaciones de esta función:
-
-### ¿Cómo puedo hacerlo?) {#transformx-array-from-array-to-default}
-
-`x` – What to transform.
-
-`array_from` – Constant array of values for converting.
-
-`array_to` – Constant array of values to convert the values in ‘from’ a.
-
-`default` – Which value to use if ‘x’ no es igual a ninguno de los valores en ‘from’.
-
-`array_from` y `array_to` – Arrays of the same size.
-
-Tipo:
-
-`transform(T, Array(T), Array(U), U) -> U`
-
-`T` y `U` pueden ser tipos numéricos, de cadena o de fecha o de fecha y hora.
-Cuando se indica la misma letra (T o U), para los tipos numéricos pueden no ser tipos coincidentes, sino tipos que tienen un tipo común.
-Por ejemplo, el primer argumento puede tener el tipo Int64, mientras que el segundo tiene el tipo Array(UInt16).
-
-Si el ‘x’ valor es igual a uno de los elementos en el ‘array_from’ matriz, devuelve el elemento existente (que está numerado igual) de la ‘array_to’ matriz. De lo contrario, devuelve ‘default’. Si hay varios elementos coincidentes en ‘array_from’, devuelve una de las coincidencias.
-
-Ejemplo:
-
-``` sql
-SELECT
-    transform(SearchEngineID, [2, 3], ['Yandex', 'Google'], 'Other') AS title,
-    count() AS c
-FROM test.hits
-WHERE SearchEngineID != 0
-GROUP BY title
-ORDER BY c DESC
-```
-
-``` text

-│ Yandex    │ 498635 │
-│ Google    │ 229872 │
-│ Other     │ 104472 │
-└───────────┴────────┘
-```
-
-### ¿Cómo puedo hacerlo?) {#transformx-array-from-array-to}
-
-Difiere de la primera variación en que el ‘default’ se omite el argumento.
-Si el ‘x’ valor es igual a uno de los elementos en el ‘array_from’ matriz, devuelve el elemento coincidente (que está numerado igual) de la ‘array_to’ matriz. De lo contrario, devuelve ‘x’.
-
-Tipo:
-
-`transform(T, Array(T), Array(T)) -> T`
-
-Ejemplo:
-
-``` sql
-SELECT
-    transform(domain(Referer), ['yandex.ru', 'google.ru', 'vk.com'], ['www.yandex', 'example.com']) AS s,
-    count() AS c
-FROM test.hits
-GROUP BY domain(Referer)
-ORDER BY count() DESC
-LIMIT 10

-# Funciones de redondeo {#rounding-functions}
-
-## piso(x\[, N\]) {#floorx-n}
-
-Devuelve el número de ronda más grande que es menor o igual que `x`. Un número redondo es un múltiplo de 1 / 10N, o el número más cercano del tipo de datos apropiado si 1 / 10N no es exacto.
-‘N’ es una constante entera, parámetro opcional. Por defecto es cero, lo que significa redondear a un entero.
-‘N’ puede ser negativo.
-
-Ejemplos: `floor(123.45, 1) = 123.4, floor(123.45, -1) = 120.`
-
-`x` es cualquier tipo numérico. El resultado es un número del mismo tipo.
-Para argumentos enteros, tiene sentido redondear con un negativo `N` valor no negativo `N` la función no hace nada).
-Si el redondeo causa desbordamiento (por ejemplo, floor(-128, -1)), se devuelve un resultado específico de la implementación.
-
-## Por ejemplo:\]) {#ceilx-n-ceilingx-n}
-
-Devuelve el número redondo más pequeño que es mayor o igual que `x`. En todos los demás sentidos, es lo mismo que el `floor` función (véase más arriba).
-
-## ¿Cómo puedo hacerlo?\]) {#truncx-n-truncatex-n}
-
-Devuelve el número redondo con el valor absoluto más grande que tiene un valor absoluto menor o igual que `x`‘s. In every other way, it is the same as the ’floor’ función (véase más arriba).
-
-## Ronda (x\[, N\]) {#rounding_functions-round}
-
-Redondea un valor a un número especificado de decimales.
-
-La función devuelve el número más cercano del orden especificado. En caso de que el número dado tenga la misma distancia que los números circundantes, la función utiliza el redondeo del banquero para los tipos de números flotantes y se redondea desde cero para los otros tipos de números.
-
-``` sql

-```
-
-**Parámetros:**
-
--   `expression` — A number to be rounded. Can be any [expresion](../syntax.md#syntax-expressions) devolviendo el numérico [tipo de datos](../../sql-reference/data-types/index.md#data_types).
--   `decimal-places` — An integer value.
-    -   Si `decimal-places > 0` luego la función redondea el valor a la derecha del punto decimal.
-    -   Si `decimal-places < 0` luego la función redondea el valor a la izquierda del punto decimal.
-    -   Si `decimal-places = 0` entonces la función redondea el valor a entero. En este caso, el argumento puede omitirse.

--   [roundBankers](#roundbankers)
-
-## roundBankers {#roundbankers}
-
-Redondea un número a una posición decimal especificada.
-
--   Si el número de redondeo está a medio camino entre dos números, la función utiliza el redondeo del banquero.
-
-        Banker's rounding is a method of rounding fractional numbers. When the rounding number is halfway between two numbers, it's rounded to the nearest even digit at the specified decimal position. For example: 3.5 rounds up to 4, 2.5 rounds down to 2.
-
-        It's the default rounding method for floating point numbers defined in [IEEE 754](https://en.wikipedia.org/wiki/IEEE_754#Roundings_to_nearest). The [round](#rounding_functions-round) function performs the same rounding for floating point numbers. The `roundBankers` function also rounds integers the same way, for example, `roundBankers(45, -1) = 40`.
-
--   En otros casos, la función redondea los números al entero más cercano.
-
-Usando el redondeo del banquero, puede reducir el efecto que tiene el redondeo de números en los resultados de sumar o restar estos números.
-
-Por ejemplo, suma números 1.5, 2.5, 3.5, 4.5 con redondeo diferente:
-
--   Sin redondeo: 1.5 + 2.5 + 3.5 + 4.5 = 12.
--   Redondeo del banquero: 2 + 2 + 4 + 4 = 12.
--   Redondeando al entero más cercano: 2 + 3 + 4 + 5 = 14.
-
-**Sintaxis**
-
-``` sql
-roundBankers(expression [, decimal_places])
-```
-
-**Parámetros**
-
--   `expression` — A number to be rounded. Can be any [expresion](../syntax.md#syntax-expressions) devolviendo el numérico [tipo de datos](../../sql-reference/data-types/index.md#data_types).
--   `decimal-places` — Decimal places. An integer number.
-    -   `decimal-places > 0` — The function rounds the number to the given position right of the decimal point. Example: `roundBankers(3.55, 1) = 3.6`.
-    -   `decimal-places < 0` — The function rounds the number to the given position left of the decimal point. Example: `roundBankers(24.55, -1) = 20`.
-    -   `decimal-places = 0` — The function rounds the number to an integer. In this case the argument can be omitted. Example: `roundBankers(2.5) = 2`.

-La cadena única, que contiene la cadena `s` repetir `n` tiempo. Si `n` \< 1, la función devuelve cadena vacía.
-
-Tipo: `String`.
-
-**Ejemplo**

-
-## inverso {#reverse}
-
-Invierte la cadena (como una secuencia de bytes).
-
-## reverseUTF8 {#reverseutf8}
-
-Invierte una secuencia de puntos de código Unicode, suponiendo que la cadena contiene un conjunto de bytes que representan un texto UTF-8. De lo contrario, hace otra cosa (no arroja una excepción).
-
-## format(pattern, s0, s1, …) {#format}
-
-Formatear el patrón constante con la cadena enumerada en los argumentos. `pattern` es un patrón de formato de Python simplificado. La cadena de formato contiene “replacement fields” rodeado de llaves `{}`. Cualquier cosa que no esté contenida entre llaves se considera texto literal, que se copia sin cambios en la salida. Si necesita incluir un carácter de llave en el texto literal, se puede escapar duplicando: `{{ '{{' }}` y `{{ '}}' }}`. Los nombres de campo pueden ser números (comenzando desde cero) o vacíos (luego se tratan como números de consecuencia).
-
-``` sql
-SELECT format('{1} {0} {1}', 'World', 'Hello')
-```
-
-``` text
-┌─format('{1} {0} {1}', 'World', 'Hello')─┐
-│ Hello World Hello                       │
-└─────────────────────────────────────────┘
-```
-
-``` sql
-SELECT format('{} {}', 'Hello', 'World')
-```
-
-``` text
-┌─format('{} {}', 'Hello', 'World')─┐
-│ Hello World                       │
-└───────────────────────────────────┘
-```
-
-## concat {#concat}
-
-Concatena las cadenas enumeradas en los argumentos, sin un separador.
-
-**Sintaxis**
-

-```
-
-**Parámetros**
-
-Valores de tipo String o FixedString.
-
-**Valores devueltos**
-
-Devuelve la cadena que resulta de concatenar los argumentos.
-
-Si alguno de los valores de argumento `NULL`, `concat` devoluciones `NULL`.
-
-**Ejemplo**
-

-
-``` sql
-SELECT concat('Hello, ', 'World!')
-```
-
-Resultado:
-
-``` text
-┌─concat('Hello, ', 'World!')─┐
-│ Hello, World!               │
-└─────────────────────────────┘
-```
-
-## ConcatAssumeInjective {#concatassumeinjective}
-
-Lo mismo que [concat](#concat), la diferencia es que usted necesita asegurar eso `concat(s1, s2, ...) → sn` es inyectivo, se utilizará para la optimización de GROUP BY.
-
-La función se llama “injective” si siempre devuelve un resultado diferente para diferentes valores de argumentos. En otras palabras: diferentes argumentos nunca arrojan un resultado idéntico.
-
-**Sintaxis**
-
-``` sql
-concatAssumeInjective(s1, s2, ...)
-```
-
-**Parámetros**
-
-Valores de tipo String o FixedString.
-
-**Valores devueltos**

----
-
-# Funciones para buscar y reemplazar en cadenas {#functions-for-searching-and-replacing-in-strings}
-
-## replaceOne(pajar, patrón, reemplazo) {#replaceonehaystack-pattern-replacement}
-
-Sustituye la primera aparición, si existe, de la ‘pattern’ subcadena en ‘haystack’ con el ‘replacement’ subcadena.
-Sucesivo, ‘pattern’ y ‘replacement’ deben ser constantes.
-
-## replaceAll (pajar, patrón, reemplazo), replace (pajar, patrón, reemplazo) {#replaceallhaystack-pattern-replacement-replacehaystack-pattern-replacement}
-
-Sustituye todas las apariciones del ‘pattern’ subcadena en ‘haystack’ con el ‘replacement’ subcadena.
-
-## replaceRegexpOne (pajar, patrón, reemplazo) {#replaceregexponehaystack-pattern-replacement}
-
-Reemplazo usando el ‘pattern’ expresión regular. Una expresión regular re2.
-Sustituye sólo la primera ocurrencia, si existe.
-Un patrón se puede especificar como ‘replacement’. Este patrón puede incluir sustituciones `\0-\9`.
-Sustitución `\0` incluye toda la expresión regular. Sustitución `\1-\9` corresponden a los números de subpatrón. `\` en una plantilla, escapar de ella usando `\`.
-También tenga en cuenta que un literal de cadena requiere un escape adicional.
-
-Ejemplo 1. Conversión de la fecha a formato americano:
-
-``` sql
-SELECT DISTINCT
-    EventDate,
-    replaceRegexpOne(toString(EventDate), '(\\d{4})-(\\d{2})-(\\d{2})', '\\2/\\3/\\1') AS res
-FROM test.hits
-LIMIT 7
-FORMAT TabSeparated
-```
-
-``` text

-2014-03-22      03/22/2014
-2014-03-23      03/23/2014
-```
-
-Ejemplo 2. Copiar una cadena diez veces:
-
-``` sql
-SELECT replaceRegexpOne('Hello, World!', '.*', '\\0\\0\\0\\0\\0\\0\\0\\0\\0\\0') AS res
-```
-
-``` text
-┌─res────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┐
-│ Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World! │
-└────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┘
-```
-
-## replaceRegexpAll (pajar, patrón, reemplazo) {#replaceregexpallhaystack-pattern-replacement}
-
-Esto hace lo mismo, pero reemplaza todas las ocurrencias. Ejemplo:
-
-``` sql
-SELECT replaceRegexpAll('Hello, World!', '.', '\\0\\0') AS res
-```
-
-``` text
-┌─res────────────────────────┐
-│ HHeelllloo,,  WWoorrlldd!! │
-└────────────────────────────┘
-```
-
-Como excepción, si una expresión regular funcionó en una subcadena vacía, el reemplazo no se realiza más de una vez.
-Ejemplo:
-
-``` sql
-SELECT replaceRegexpAll('Hello, World!', '^', 'here: ') AS res
-```
-
-``` text
-┌─res─────────────────┐
-│ here: Hello, World! │
-└─────────────────────┘
-```
-
-## Sistema abierto.) {#regexpquotemetas}
-
-La función agrega una barra invertida antes de algunos caracteres predefinidos en la cadena.
-Caracteres predefinidos: ‘0’, ‘\\’, ‘\|’, ‘(’, ‘)’, ‘^’, ‘$’, ‘.’, ‘\[’, '\]', ‘?’, '\*‘,’+‘,’{‘,’:‘,’-'.
-Esta implementación difiere ligeramente de re2::RE2::QuoteMeta. Escapa de byte cero como \\0 en lugar de 00 y escapa solo de los caracteres requeridos.
-Para obtener más información, consulte el enlace: [RE2](https://github.com/google/re2/blob/master/re2/re2.cc#L473)

-## multiSearchAllPositions {#multisearchallpositions}
-
-Lo mismo que [posición](string-search-functions.md#position) pero devuelve `Array` posiciones (en bytes) de las subcadenas correspondientes encontradas en la cadena. Las posiciones se indexan a partir de 1.
-
-La búsqueda se realiza en secuencias de bytes sin respecto a la codificación de cadenas y la intercalación.
-
--   Para la búsqueda ASCII sin distinción de mayúsculas y minúsculas, utilice la función `multiSearchAllPositionsCaseInsensitive`.
--   Para buscar en UTF-8, use la función [MultiSearchAllPositionsUTF8](#multiSearchAllPositionsUTF8).
--   Para la búsqueda UTF-8 sin distinción de mayúsculas y minúsculas, utilice la función multiSearchAllPositionsCaseInsensitiveUTF8.
-
-**Sintaxis**
-
-``` sql
-multiSearchAllPositions(haystack, [needle1, needle2, ..., needlen])
-```
-
-**Parámetros**
-
--   `haystack` — string, in which substring will to be searched. [Cadena](../syntax.md#syntax-string-literal).
--   `needle` — substring to be searched. [Cadena](../syntax.md#syntax-string-literal).
-
-**Valores devueltos**

-## MultiSearchAllPositionsUTF8 {#multiSearchAllPositionsUTF8}
-
-Ver `multiSearchAllPositions`.
-
-## multiSearchFirstPosition(pajar, \[aguja<sub>1</sub>, aguja<sub>2</sub>, …, needle<sub>y</sub>\]) {#multisearchfirstposition}
-
-Lo mismo que `position` pero devuelve el desplazamiento más a la izquierda de la cadena `haystack` que se corresponde con algunas de las agujas.
-
-Para una búsqueda que no distingue entre mayúsculas y minúsculas o / y en formato UTF-8, use funciones `multiSearchFirstPositionCaseInsensitive, multiSearchFirstPositionUTF8, multiSearchFirstPositionCaseInsensitiveUTF8`.
-
-## multiSearchFirstIndex(pajar, \[aguja<sub>1</sub>, aguja<sub>2</sub>, …, needle<sub>y</sub>\]) {#multisearchfirstindexhaystack-needle1-needle2-needlen}
-
-Devuelve el índice `i` (a partir de 1) de la aguja encontrada más a la izquierda<sub>me</sub> en la cadena `haystack` y 0 de lo contrario.
-
-Para una búsqueda que no distingue entre mayúsculas y minúsculas o / y en formato UTF-8, use funciones `multiSearchFirstIndexCaseInsensitive, multiSearchFirstIndexUTF8, multiSearchFirstIndexCaseInsensitiveUTF8`.
-
-## multiSearchAny(pajar, \[aguja<sub>1</sub>, aguja<sub>2</sub>, …, needle<sub>y</sub>\]) {#function-multisearchany}
-
-Devuelve 1, si al menos una aguja de cuerda<sub>me</sub> coincide con la cadena `haystack` y 0 de lo contrario.
-
-Para una búsqueda que no distingue entre mayúsculas y minúsculas o / y en formato UTF-8, use funciones `multiSearchAnyCaseInsensitive, multiSearchAnyUTF8, multiSearchAnyCaseInsensitiveUTF8`.
-
-!!! note "Nota"
-    En todos `multiSearch*` el número de agujas debe ser inferior a 2<sup>8</sup> debido a la especificación de implementación.
-
-## match (pajar, patrón) {#matchhaystack-pattern}
-
-Comprueba si la cadena coincide con la `pattern` expresión regular. Un `re2` expresión regular. El [sintaxis](https://github.com/google/re2/wiki/Syntax) de la `re2` expresiones regulares es más limitada que la sintaxis de las expresiones regulares de Perl.
-
-Devuelve 0 si no coincide, o 1 si coincide.
-
-Tenga en cuenta que el símbolo de barra invertida (`\`) se utiliza para escapar en la expresión regular. El mismo símbolo se usa para escapar en literales de cadena. Por lo tanto, para escapar del símbolo en una expresión regular, debe escribir dos barras invertidas (\\) en un literal de cadena.
-
-La expresión regular funciona con la cadena como si fuera un conjunto de bytes. La expresión regular no puede contener bytes nulos.
-Para que los patrones busquen subcadenas en una cadena, es mejor usar LIKE o ‘position’, ya que trabajan mucho más rápido.
-
-## multiMatchAny(pajar, \[patrón<sub>1</sub>, patrón<sub>2</sub>, …, pattern<sub>y</sub>\]) {#multimatchanyhaystack-pattern1-pattern2-patternn}
-
-Lo mismo que `match`, pero devuelve 0 si ninguna de las expresiones regulares coincide y 1 si alguno de los patrones coincide. Se utiliza [hyperscan](https://github.com/intel/hyperscan) biblioteca. Para que los patrones busquen subcadenas en una cadena, es mejor usar `multiSearchAny` ya que funciona mucho más rápido.
-
-!!! note "Nota"
-    La longitud de cualquiera de los `haystack` cadena debe ser inferior a 2<sup>32</sup> bytes de lo contrario, se lanza la excepción. Esta restricción tiene lugar debido a la API de hiperscan.
-
-## multiMatchAnyIndex(pajar, \[patrón<sub>1</sub>, patrón<sub>2</sub>, …, pattern<sub>y</sub>\]) {#multimatchanyindexhaystack-pattern1-pattern2-patternn}
-
-Lo mismo que `multiMatchAny`, pero devuelve cualquier índice que coincida con el pajar.
-
-## ¿Cómo puedo obtener más información?<sub>1</sub>, patrón<sub>2</sub>, …, pattern<sub>y</sub>\]) {#multimatchallindiceshaystack-pattern1-pattern2-patternn}
-
-Lo mismo que `multiMatchAny`, pero devuelve la matriz de todas las indicaciones que coinciden con el pajar en cualquier orden.
-
-## multiFuzzyMatchAny(pajar, distancia, \[patrón<sub>1</sub>, patrón<sub>2</sub>, …, pattern<sub>y</sub>\]) {#multifuzzymatchanyhaystack-distance-pattern1-pattern2-patternn}
-
-Lo mismo que `multiMatchAny`, pero devuelve 1 si algún patrón coincide con el pajar dentro de una constante [editar distancia](https://en.wikipedia.org/wiki/Edit_distance). Esta función también está en modo experimental y puede ser extremadamente lenta. Para obtener más información, consulte [documentación de hyperscan](https://intel.github.io/hyperscan/dev-reference/compilation.html#approximate-matching).
-
-## multiFuzzyMatchAnyIndex(pajar, distancia, \[patrón<sub>1</sub>, patrón<sub>2</sub>, …, pattern<sub>y</sub>\]) {#multifuzzymatchanyindexhaystack-distance-pattern1-pattern2-patternn}
-
-Lo mismo que `multiFuzzyMatchAny`, pero devuelve cualquier índice que coincida con el pajar dentro de una distancia de edición constante.
-
-## multiFuzzyMatchAllIndices(pajar, distancia, \[patrón<sub>1</sub>, patrón<sub>2</sub>, …, pattern<sub>y</sub>\]) {#multifuzzymatchallindiceshaystack-distance-pattern1-pattern2-patternn}
-
-Lo mismo que `multiFuzzyMatchAny`, pero devuelve la matriz de todos los índices en cualquier orden que coincida con el pajar dentro de una distancia de edición constante.
-
-!!! note "Nota"
-    `multiFuzzyMatch*` las funciones no admiten expresiones regulares UTF-8, y dichas expresiones se tratan como bytes debido a la restricción de hiperscan.
-
-!!! note "Nota"
-    Para desactivar todas las funciones que utilizan hyperscan, utilice la configuración `SET allow_hyperscan = 0;`.
-
-## extracto(pajar, patrón) {#extracthaystack-pattern}
-
-Extrae un fragmento de una cadena utilizando una expresión regular. Si ‘haystack’ no coincide con el ‘pattern’ regex, se devuelve una cadena vacía. Si la expresión regular no contiene subpatrones, toma el fragmento que coincide con toda la expresión regular. De lo contrario, toma el fragmento que coincide con el primer subpatrón.
-
-## extractAll(pajar, patrón) {#extractallhaystack-pattern}
-
-Extrae todos los fragmentos de una cadena utilizando una expresión regular. Si ‘haystack’ no coincide con el ‘pattern’ regex, se devuelve una cadena vacía. Devuelve una matriz de cadenas que consiste en todas las coincidencias con la expresión regular. En general, el comportamiento es el mismo que el ‘extract’ función (toma el primer subpatrón, o la expresión completa si no hay un subpatrón).
-
-## como (pajar, patrón), operador de patrón COMO pajar {#function-like}
-
-Comprueba si una cadena coincide con una expresión regular simple.
-La expresión regular puede contener los metasímbolos `%` y `_`.
-
-`%` indica cualquier cantidad de bytes (incluidos cero caracteres).
-
-`_` indica cualquier byte.
-
-Utilice la barra invertida (`\`) para escapar de metasímbolos. Vea la nota sobre el escape en la descripción del ‘match’ función.
-
-Para expresiones regulares como `%needle%`, el código es más óptimo y trabaja tan rápido como el `position` función.
-Para otras expresiones regulares, el código es el mismo que para ‘match’ función.
-
-## notLike(haystack, pattern), haystack NOT LIKE operador de patrón {#function-notlike}
-
-Lo mismo que ‘like’ pero negativo.
-
-## ngramDistance(pajar, aguja) {#ngramdistancehaystack-needle}
-
-Calcula la distancia de 4 gramos entre `haystack` y `needle`: counts the symmetric difference between two multisets of 4-grams and normalizes it by the sum of their cardinalities. Returns float number from 0 to 1 – the closer to zero, the more strings are similar to each other. If the constant `needle` o `haystack` es más de 32Kb, arroja una excepción. Si algunos de los no constantes `haystack` o `needle` Las cadenas son más de 32Kb, la distancia es siempre una.
-
-Para la búsqueda sin distinción de mayúsculas y minúsculas o / y en formato UTF-8, use funciones `ngramDistanceCaseInsensitive, ngramDistanceUTF8, ngramDistanceCaseInsensitiveUTF8`.
-
-## ngramSearch(pajar, aguja) {#ngramsearchhaystack-needle}
-
-Lo mismo que `ngramDistance` pero calcula la diferencia no simétrica entre `needle` y `haystack` – the number of n-grams from needle minus the common number of n-grams normalized by the number of `needle` n-gramas. Cuanto más cerca de uno, más probable es `needle` está en el `haystack`. Puede ser útil para la búsqueda de cadenas difusas.
-
-Para la búsqueda sin distinción de mayúsculas y minúsculas o / y en formato UTF-8, use funciones `ngramSearchCaseInsensitive, ngramSearchUTF8, ngramSearchCaseInsensitiveUTF8`.
-
-!!! note "Nota"
-    For UTF-8 case we use 3-gram distance. All these are not perfectly fair n-gram distances. We use 2-byte hashes to hash n-grams and then calculate the (non-)symmetric difference between these hash tables – collisions may occur. With UTF-8 case-insensitive format we do not use fair `tolower` function – we zero the 5-th bit (starting from zero) of each codepoint byte and first bit of zeroth byte if bytes more than one – this works for Latin and mostly for all Cyrillic letters.

-
-## Problemas comunes de conversiones numéricas {#numeric-conversion-issues}
-
-Cuando convierte un valor de uno a otro tipo de datos, debe recordar que, en un caso común, es una operación insegura que puede provocar una pérdida de datos. Puede producirse una pérdida de datos si intenta ajustar el valor de un tipo de datos más grande a un tipo de datos más pequeño, o si convierte valores entre diferentes tipos de datos.
-
-ClickHouse tiene el [mismo comportamiento que los programas de C++](https://en.cppreference.com/w/cpp/language/implicit_conversion).
-
-## ¿Cómo puedo obtener más información?) {#toint8163264}
-
-Convierte un valor de entrada en el [En](../../sql-reference/data-types/int-uint.md) tipo de datos. Esta familia de funciones incluye:
-
--   `toInt8(expr)` — Results in the `Int8` tipo de datos.
--   `toInt16(expr)` — Results in the `Int16` tipo de datos.
--   `toInt32(expr)` — Results in the `Int32` tipo de datos.
--   `toInt64(expr)` — Results in the `Int64` tipo de datos.
-
-**Parámetros**
-
--   `expr` — [Expresion](../syntax.md#syntax-expressions) devolviendo un número o una cadena con la representación decimal de un número. No se admiten representaciones binarias, octales y hexadecimales de números. Los ceros principales son despojados.
-
-**Valor devuelto**
-
-Valor entero en el `Int8`, `Int16`, `Int32`, o `Int64` tipo de datos.
-
-Funciones de uso [redondeando hacia cero](https://en.wikipedia.org/wiki/Rounding#Rounding_towards_zero), lo que significa que truncan dígitos fraccionarios de números.
-
-El comportamiento de las funciones [NaN y Inf](../../sql-reference/data-types/float.md#data_type-float-nan-inf) los argumentos no están definidos. Recuerde acerca de [problemas de conversión numérica](#numeric-conversion-issues), al usar las funciones.

-## ToString {#tostring}
-
-Funciones para convertir entre números, cadenas (pero no cadenas fijas), fechas y fechas con horas.
-Todas estas funciones aceptan un argumento.
-
-Al convertir a o desde una cadena, el valor se formatea o se analiza utilizando las mismas reglas que para el formato TabSeparated (y casi todos los demás formatos de texto). Si la cadena no se puede analizar, se lanza una excepción y se cancela la solicitud.
-
-Al convertir fechas a números o viceversa, la fecha corresponde al número de días desde el comienzo de la época Unix.
-Al convertir fechas con horas a números o viceversa, la fecha con hora corresponde al número de segundos desde el comienzo de la época Unix.
-
-Los formatos de fecha y fecha con hora para las funciones toDate/toDateTime se definen de la siguiente manera:
-
-``` text
-YYYY-MM-DD
-YYYY-MM-DD hh:mm:ss
-```
-
-Como excepción, si convierte de tipos numéricos UInt32, Int32, UInt64 o Int64 a Date, y si el número es mayor o igual que 65536, el número se interpreta como una marca de tiempo Unix (y no como el número de días) y se redondea a la fecha. Esto permite soporte para la ocurrencia común de la escritura ‘toDate(unix_timestamp)’, que de otra manera sería un error y requeriría escribir el más engorroso ‘toDate(toDateTime(unix_timestamp))’.
-
-La conversión entre una fecha y una fecha con la hora se realiza de la manera natural: agregando un tiempo nulo o eliminando el tiempo.
-
-La conversión entre tipos numéricos utiliza las mismas reglas que las asignaciones entre diferentes tipos numéricos en C++.
-
-Además, la función toString del argumento DateTime puede tomar un segundo argumento String que contiene el nombre de la zona horaria. Ejemplo: `Asia/Yekaterinburg` En este caso, la hora se formatea de acuerdo con la zona horaria especificada.
-
-``` sql
-SELECT
-    now() AS now_local,
-    toString(now(), 'Asia/Yekaterinburg') AS now_yekat
-```
-
-``` text
-┌───────────now_local─┬─now_yekat───────────┐
-│ 2016-06-15 00:11:21 │ 2016-06-15 02:11:21 │
-└─────────────────────┴─────────────────────┘
-```
-
-Ver también el `toUnixTimestamp` función.
-
-## ¿Qué puedes encontrar en Neodigit) {#tofixedstrings-n}
-
-Convierte un argumento de tipo String en un tipo FixedString(N) (una cadena con longitud fija N). N debe ser una constante.
-Si la cadena tiene menos bytes que N, se rellena con bytes nulos a la derecha. Si la cadena tiene más bytes que N, se produce una excepción.
-
-## Todos los derechos reservados.) {#tostringcuttozeros}
-
-Acepta un argumento String o FixedString. Devuelve la cadena con el contenido truncado en el primer byte cero encontrado.
-
-Ejemplo:
-
-``` sql
-SELECT toFixedString('foo', 8) AS s, toStringCutToZero(s) AS s_cut
-```
-
-``` text
-┌─s─────────────┬─s_cut─┐
-│ foo\0\0\0\0\0 │ foo   │

-Estas funciones aceptan una cadena e interpretan los bytes colocados al principio de la cadena como un número en orden de host (little endian). Si la cadena no es lo suficientemente larga, las funciones funcionan como si la cadena estuviera rellenada con el número necesario de bytes nulos. Si la cadena es más larga de lo necesario, se ignoran los bytes adicionales. Una fecha se interpreta como el número de días desde el comienzo de la época Unix, y una fecha con hora se interpreta como el número de segundos desde el comienzo de la época Unix.
-
-## reinterpretAsString {#type_conversion_functions-reinterpretAsString}
-
-Esta función acepta un número o fecha o fecha con hora, y devuelve una cadena que contiene bytes que representan el valor correspondiente en orden de host (little endian). Los bytes nulos se eliminan desde el final. Por ejemplo, un valor de tipo UInt32 de 255 es una cadena que tiene un byte de longitud.
-
-## reinterpretAsFixedString {#reinterpretasfixedstring}
-
-Esta función acepta un número o fecha o fecha con hora, y devuelve un FixedString que contiene bytes que representan el valor correspondiente en orden de host (little endian). Los bytes nulos se eliminan desde el final. Por ejemplo, un valor de tipo UInt32 de 255 es un FixedString que tiene un byte de longitud.
-
-## CAST(x, T) {#type_conversion_function-cast}
-
-Convertir ‘x’ a la ‘t’ tipo de datos. La sintaxis CAST(x AS t) también es compatible.
-
-Ejemplo:
-
-``` sql
-SELECT
-    '2016-06-15 23:00:00' AS timestamp,
-    CAST(timestamp AS DateTime) AS datetime,
-    CAST(timestamp AS Date) AS date,
-    CAST(timestamp, 'String') AS string,
-    CAST(timestamp, 'FixedString(22)') AS fixed_string
-```

-
-## toInterval(Year\|Quarter\|Month\|Week\|Day\|Hour\|Minute\|Second) {#function-tointerval}
-
-Convierte un argumento de tipo Number en un [Intervalo](../../sql-reference/data-types/special-data-types/interval.md) tipo de datos.
-
-**Sintaxis**
-

-
-Convierte una fecha y una hora en el [Cadena](../../sql-reference/data-types/string.md) representación a [FechaHora](../../sql-reference/data-types/datetime.md#data_type-datetime) tipo de datos.
-
-La función analiza [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601), [RFC 1123 - 5.2.14 RFC-822 Especificación de fecha y hora](https://tools.ietf.org/html/rfc1123#page-55), ClickHouse y algunos otros formatos de fecha y hora.

-toc_title: Trabajando con Yandex.Diccionarios de Metrica
----
-
-# Funciones para trabajar con Yandex.Diccionarios de Metrica {#functions-for-working-with-yandex-metrica-dictionaries}
-
-Para que las funciones a continuación funcionen, la configuración del servidor debe especificar las rutas y direcciones para obtener todo el Yandex.Diccionarios Metrica. Los diccionarios se cargan en la primera llamada de cualquiera de estas funciones. Si las listas de referencia no se pueden cargar, se lanza una excepción.
-
-Para obtener información sobre cómo crear listas de referencia, consulte la sección “Dictionaries”.
-
-## Múltiples Geobases {#multiple-geobases}
-
-ClickHouse admite trabajar con múltiples geobases alternativas (jerarquías regionales) simultáneamente, con el fin de soportar diversas perspectivas sobre a qué países pertenecen ciertas regiones.
-
-El ‘clickhouse-server’ config especifica el archivo con la jerarquía regional::`<path_to_regions_hierarchy_file>/opt/geo/regions_hierarchy.txt</path_to_regions_hierarchy_file>`
-
-Además de este archivo, también busca archivos cercanos que tengan el símbolo _ y cualquier sufijo anexado al nombre (antes de la extensión del archivo).
-Por ejemplo, también encontrará el archivo `/opt/geo/regions_hierarchy_ua.txt` si está presente.
-
-`ua` se llama la clave del diccionario. Para un diccionario sin un sufijo, la clave es una cadena vacía.
-
-Todos los diccionarios se vuelven a cargar en tiempo de ejecución (una vez cada cierto número de segundos, como se define en el parámetro de configuración builtin_dictionaries_reload_interval , o una vez por hora por defecto). Sin embargo, la lista de diccionarios disponibles se define una vez, cuando se inicia el servidor.
-
-All functions for working with regions have an optional argument at the end – the dictionary key. It is referred to as the geobase.
-Ejemplo:
-
-``` sql
-regionToCountry(RegionID) – Uses the default dictionary: /opt/geo/regions_hierarchy.txt
-regionToCountry(RegionID, '') – Uses the default dictionary: /opt/geo/regions_hierarchy.txt
-regionToCountry(RegionID, 'ua') – Uses the dictionary for the 'ua' key: /opt/geo/regions_hierarchy_ua.txt
-```
-
-### ¿Cómo puedo hacerlo?\]) {#regiontocityid-geobase}
-
-Accepts a UInt32 number – the region ID from the Yandex geobase. If this region is a city or part of a city, it returns the region ID for the appropriate city. Otherwise, returns 0.
-
-### ¿Cómo puedo hacerlo?\]) {#regiontoareaid-geobase}
-
-Convierte una región en un área (tipo 5 en la geobase). En todos los demás sentidos, esta función es la misma que ‘regionToCity’.
-
-``` sql
-SELECT DISTINCT regionToName(regionToArea(toUInt32(number), 'ua'))
-FROM system.numbers
-LIMIT 15
-```

-### IN Operadores {#select-in-operators}
-
-El `IN`, `NOT IN`, `GLOBAL IN`, y `GLOBAL NOT IN` están cubiertos por separado, ya que su funcionalidad es bastante rica.
-
-El lado izquierdo del operador es una sola columna o una tupla.
-
-Ejemplos:
-
-``` sql
-SELECT UserID IN (123, 456) FROM ...
-SELECT (CounterID, UserID) IN ((34, 123), (101500, 456)) FROM ...
-```
-
-Si el lado izquierdo es una sola columna que está en el índice, y el lado derecho es un conjunto de constantes, el sistema usa el índice para procesar la consulta.
-
-Don't list too many values explicitly (i.e. millions). If a data set is large, put it in a temporary table (for example, see the section “External data for query processing”), luego use una subconsulta.
-
-El lado derecho del operador puede ser un conjunto de expresiones constantes, un conjunto de tuplas con expresiones constantes (mostradas en los ejemplos anteriores) o el nombre de una tabla de base de datos o subconsulta SELECT entre paréntesis.
-
-Si el lado derecho del operador es el nombre de una tabla (por ejemplo, `UserID IN users`), esto es equivalente a la subconsulta `UserID IN (SELECT * FROM users)`. Úselo cuando trabaje con datos externos que se envían junto con la consulta. Por ejemplo, la consulta se puede enviar junto con un conjunto de ID de usuario ‘users’ tabla temporal, que debe ser filtrada.
-
-Si el lado derecho del operador es un nombre de tabla que tiene el motor Set (un conjunto de datos preparado que siempre está en RAM), el conjunto de datos no se volverá a crear para cada consulta.
-
-La subconsulta puede especificar más de una columna para filtrar tuplas.
-Ejemplo:
-
-``` sql
-SELECT (CounterID, UserID) IN (SELECT CounterID, UserID FROM ...) FROM ...
-```
-
-Las columnas a la izquierda y a la derecha del operador IN deben tener el mismo tipo.
-
-El operador IN y la subconsulta pueden aparecer en cualquier parte de la consulta, incluidas las funciones agregadas y las funciones lambda.
-Ejemplo:
-
-``` sql
-SELECT
-    EventDate,
-    avg(UserID IN
-    (
-        SELECT UserID
-        FROM test.hits
-        WHERE EventDate = toDate('2014-03-17')
-    )) AS ratio
-FROM test.hits
-GROUP BY EventDate
-ORDER BY EventDate ASC
-```
-
-``` text
-┌──EventDate─┬────ratio─┐

-│ 2014-03-18 │ 0.807696 │

-└────────────┴──────────┘
-```
-
-Para cada día después del 17 de marzo, cuente el porcentaje de páginas vistas realizadas por los usuarios que visitaron el sitio el 17 de marzo.
-Una subconsulta en la cláusula IN siempre se ejecuta una sola vez en un único servidor. No hay subconsultas dependientes.
-
-## Procesamiento NULL {#null-processing-1}
-
-Durante el procesamiento de la solicitud, el operador IN asume que el resultado de una operación [NULL](../syntax.md#null-literal) siempre es igual a `0`, independientemente de si `NULL` está en el lado derecho o izquierdo del operador. `NULL` Los valores no se incluyen en ningún conjunto de datos, no se corresponden entre sí y no se pueden comparar.
-
-Aquí hay un ejemplo con el `t_null` tabla:
-
-``` text
-┌─x─┬────y─┐
-│ 1 │ ᴺᵁᴸᴸ │
-│ 2 │    3 │
-└───┴──────┘
-```
-
-Ejecución de la consulta `SELECT x FROM t_null WHERE y IN (NULL,3)` da el siguiente resultado:
-
-``` text
-┌─x─┐
-│ 2 │
-└───┘
-```
-
-Se puede ver que la fila en la que `y = NULL` se expulsa de los resultados de la consulta. Esto se debe a que ClickHouse no puede decidir si `NULL` está incluido en el `(NULL,3)` conjunto, devuelve `0` como resultado de la operación, y `SELECT` excluye esta fila de la salida final.
-
-``` sql
-SELECT y IN (NULL, 3)
-FROM t_null
-```
-
-``` text
-┌─in(y, tuple(NULL, 3))─┐
-│                     0 │
-│                     1 │
-└───────────────────────┘
-```
-
-## Subconsultas distribuidas {#select-distributed-subqueries}
-
-Hay dos opciones para IN-s con subconsultas (similar a JOINs): normal `IN` / `JOIN` y `GLOBAL IN` / `GLOBAL JOIN`. Se diferencian en cómo se ejecutan para el procesamiento de consultas distribuidas.
-
-!!! attention "Atención"
-    Recuerde que los algoritmos descritos a continuación pueden funcionar de manera diferente dependiendo de la [configuración](../../operations/settings/settings.md) `distributed_product_mode` configuración.
-
-Cuando se utiliza el IN normal, la consulta se envía a servidores remotos, y cada uno de ellos ejecuta las subconsultas en el `IN` o `JOIN` clausula.
-
-Cuando se utiliza `GLOBAL IN` / `GLOBAL JOINs`, primero todas las subconsultas se ejecutan para `GLOBAL IN` / `GLOBAL JOINs`, y los resultados se recopilan en tablas temporales. A continuación, las tablas temporales se envían a cada servidor remoto, donde las consultas se ejecutan utilizando estos datos temporales.
-
-Para una consulta no distribuida, utilice el `IN` / `JOIN`.
-
-Tenga cuidado al usar subconsultas en el `IN` / `JOIN` para el procesamiento de consultas distribuidas.
-
-Veamos algunos ejemplos. Supongamos que cada servidor del clúster tiene un **local_table**. Cada servidor también tiene un **distributed_table** mesa con el **Distribuido** tipo, que mira todos los servidores del clúster.
-
-Para una consulta al **distributed_table**, la consulta se enviará a todos los servidores remotos y se ejecutará en ellos usando el **local_table**.
-
-Por ejemplo, la consulta
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table
-```
-
-se enviará a todos los servidores remotos como
-
-``` sql
-SELECT uniq(UserID) FROM local_table
-```
-
-y ejecutar en cada uno de ellos en paralelo, hasta que llegue a la etapa donde se pueden combinar resultados intermedios. Luego, los resultados intermedios se devolverán al servidor solicitante y se fusionarán en él, y el resultado final se enviará al cliente.
-
-Ahora examinemos una consulta con IN:
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM local_table WHERE CounterID = 34)
-```
-
--   Cálculo de la intersección de audiencias de dos sitios.
-
-Esta consulta se enviará a todos los servidores remotos como
-
-``` sql
-SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM local_table WHERE CounterID = 34)
-```
-
-En otras palabras, los datos establecidos en la cláusula IN se recopilarán en cada servidor de forma independiente, solo a través de los datos que se almacenan localmente en cada uno de los servidores.
-
-Esto funcionará correctamente y de manera óptima si está preparado para este caso y ha distribuido datos en los servidores de clúster de modo que los datos de un único ID de usuario residen completamente en un único servidor. En este caso, todos los datos necesarios estarán disponibles localmente en cada servidor. De lo contrario, el resultado será inexacto. Nos referimos a esta variación de la consulta como “local IN”.
-
-Para corregir cómo funciona la consulta cuando los datos se distribuyen aleatoriamente entre los servidores de clúster, puede especificar **distributed_table** dentro de una subconsulta. La consulta se vería así:
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)
-```
-
-Esta consulta se enviará a todos los servidores remotos como
-
-``` sql
-SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)
-```
-
-La subconsulta comenzará a ejecutarse en cada servidor remoto. Dado que la subconsulta utiliza una tabla distribuida, la subconsulta que se encuentra en cada servidor remoto se reenviará a cada servidor remoto como
-
-``` sql
-SELECT UserID FROM local_table WHERE CounterID = 34
-```
-
-Por ejemplo, si tiene un clúster de 100 servidores, la ejecución de toda la consulta requerirá 10.000 solicitudes elementales, lo que generalmente se considera inaceptable.
-
-En tales casos, siempre debe usar GLOBAL IN en lugar de IN. Veamos cómo funciona para la consulta
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID GLOBAL IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)
-```
-
-El servidor del solicitante ejecutará la subconsulta
-
-``` sql
-SELECT UserID FROM distributed_table WHERE CounterID = 34
-```
-
-y el resultado se colocará en una tabla temporal en la RAM. A continuación, la solicitud se enviará a cada servidor remoto como
-
-``` sql
-SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID GLOBAL IN _data1
-```
-
-y la tabla temporal `_data1` se enviará a cada servidor remoto con la consulta (el nombre de la tabla temporal está definido por la implementación).
-
-Esto es más óptimo que usar el IN normal. Sin embargo, tenga en cuenta los siguientes puntos:
-
-1.  Al crear una tabla temporal, los datos no se hacen únicos. Para reducir el volumen de datos transmitidos a través de la red, especifique DISTINCT en la subconsulta. (No necesita hacer esto para un IN normal.)
-2.  La tabla temporal se enviará a todos los servidores remotos. La transmisión no tiene en cuenta la topología de red. Por ejemplo, si 10 servidores remotos residen en un centro de datos que es muy remoto en relación con el servidor solicitante, los datos se enviarán 10 veces a través del canal al centro de datos remoto. Intente evitar grandes conjuntos de datos cuando use GLOBAL IN.
-3.  Al transmitir datos a servidores remotos, las restricciones en el ancho de banda de la red no son configurables. Puede sobrecargar la red.
-4.  Intente distribuir datos entre servidores para que no necesite usar GLOBAL IN de forma regular.
-5.  Si necesita utilizar GLOBAL IN con frecuencia, planifique la ubicación del clúster ClickHouse para que un único grupo de réplicas resida en no más de un centro de datos con una red rápida entre ellos, de modo que una consulta se pueda procesar completamente dentro de un único centro de datos.
-
-También tiene sentido especificar una tabla local en el `GLOBAL IN` cláusula, en caso de que esta tabla local solo esté disponible en el servidor solicitante y desee usar datos de ella en servidores remotos.

-    Los intervalos con diferentes tipos no se pueden combinar. No puedes usar expresiones como `INTERVAL 4 DAY 1 HOUR`. Especifique intervalos en unidades que sean más pequeñas o iguales que la unidad más pequeña del intervalo, por ejemplo, `INTERVAL 25 HOUR`. Puede usar operaciones consecutivas, como en el siguiente ejemplo.

-
-Nota:
-
-El operador condicional calcula los valores de b y c, luego verifica si se cumple la condición a y luego devuelve el valor correspondiente. Si `b` o `C` es una [arrayJoin()](../../sql-reference/functions/array-join.md#functions_arrayjoin) función, cada fila se replicará independientemente de la “a” condición.

-
-Si `x` se especifica, entonces `transform(x, [a, ...], [b, ...], c)` function is used. Otherwise – `multiIf(a, b, ..., c)`.
-
-Si no hay `ELSE c` cláusula en la expresión, el valor predeterminado es `NULL`.

-`[x1, ...]` – The `array(x1, ...) function.`
-
-## Operador de creación de tupla {#tuple-creation-operator}
-
-`(x1, x2, ...)` – The `tuple(x2, x2, ...) function.`
-
-## Asociatividad {#associativity}
-
-Todos los operadores binarios han dejado asociatividad. Por ejemplo, `1 + 2 + 3` se transforma a `plus(plus(1, 2), 3)`.
-A veces esto no funciona de la manera que esperas. Por ejemplo, `SELECT 4 > 2 > 3` resultará en 0.
-
-Para la eficiencia, el `and` y `or` funciones aceptan cualquier número de argumentos. Las cadenas correspondientes de `AND` y `OR` operadores se transforman en una sola llamada de estas funciones.
-
-## Comprobación de `NULL` {#checking-for-null}
-
-ClickHouse soporta el `IS NULL` y `IS NOT NULL` operador.
-
-### IS NULL {#operator-is-null}
-
--   Para [NULL](../../sql-reference/data-types/nullable.md) valores de tipo, el `IS NULL` operador devuelve:
-    -   `1` si el valor es `NULL`.
-    -   `0` de lo contrario.
--   Para otros valores, el `IS NULL` operador siempre devuelve `0`.

-## ALTER {#query_language_queries_alter}
-
-El `ALTER` consulta sólo se admite para `*MergeTree` mesas, así como `Merge`y`Distributed`. La consulta tiene varias variaciones.
-
-### Manipulaciones de columna {#column-manipulations}
-
-Cambiar la estructura de la tabla.
-
-``` sql
-ALTER TABLE [db].name [ON CLUSTER cluster] ADD|DROP|CLEAR|COMMENT|MODIFY COLUMN ...
-```
-
-En la consulta, especifique una lista de una o más acciones separadas por comas.
-Cada acción es una operación en una columna.
-
-Se admiten las siguientes acciones:
-
--   [ADD COLUMN](#alter_add-column) — Adds a new column to the table.
--   [DROP COLUMN](#alter_drop-column) — Deletes the column.
--   [CLEAR COLUMN](#alter_clear-column) — Resets column values.
--   [COMMENT COLUMN](#alter_comment-column) — Adds a text comment to the column.
--   [MODIFY COLUMN](#alter_modify-column) — Changes column's type, default expression and TTL.
-
-Estas acciones se describen en detalle a continuación.
-
-#### ADD COLUMN {#alter_add-column}
-
-``` sql
-ADD COLUMN [IF NOT EXISTS] name [type] [default_expr] [codec] [AFTER name_after]
-```
-
-Agrega una nueva columna a la tabla con el `name`, `type`, [`codec`](create.md#codecs) y `default_expr` (ver la sección [Expresiones predeterminadas](create.md#create-default-values)).
-
-Si el `IF NOT EXISTS` cláusula, la consulta no devolverá un error si la columna ya existe. Si especifica `AFTER name_after` (el nombre de otra columna), la columna se agrega después de la especificada en la lista de columnas de tabla. De lo contrario, la columna se agrega al final de la tabla. Tenga en cuenta que no hay forma de agregar una columna al principio de una tabla. Para una cadena de acciones, `name_after` puede ser el nombre de una columna que se agrega en una de las acciones anteriores.
-
-Agregar una columna solo cambia la estructura de la tabla, sin realizar ninguna acción con datos. Los datos no aparecen en el disco después de `ALTER`. Si faltan los datos para una columna al leer de la tabla, se rellena con valores predeterminados (realizando la expresión predeterminada si hay una, o usando ceros o cadenas vacías). La columna aparece en el disco después de fusionar partes de datos (consulte [Método de codificación de datos:](../../engines/table-engines/mergetree-family/mergetree.md)).
-
-Este enfoque nos permite completar el `ALTER` consulta al instante, sin aumentar el volumen de datos antiguos.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits ADD COLUMN browser String AFTER user_id
-```
-
-#### DROP COLUMN {#alter_drop-column}
-
-``` sql
-DROP COLUMN [IF EXISTS] name
-```
-
-Elimina la columna con el nombre `name`. Si el `IF EXISTS` se especifica una cláusula, la consulta no devolverá un error si la columna no existe.
-
-Elimina datos del sistema de archivos. Dado que esto elimina archivos completos, la consulta se completa casi al instante.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits DROP COLUMN browser
-```
-
-#### CLEAR COLUMN {#alter_clear-column}
-
-``` sql
-CLEAR COLUMN [IF EXISTS] name IN PARTITION partition_name
-```
-
-Restablece todos los datos de una columna para una partición especificada. Obtenga más información sobre cómo configurar el nombre de la partición en la sección [Cómo especificar la expresión de partición](#alter-how-to-specify-part-expr).
-
-Si el `IF EXISTS` se especifica una cláusula, la consulta no devolverá un error si la columna no existe.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits CLEAR COLUMN browser IN PARTITION tuple()
-```
-
-#### COMMENT COLUMN {#alter_comment-column}
-
-``` sql
-COMMENT COLUMN [IF EXISTS] name 'comment'
-```
-
-Agrega un comentario a la columna. Si el `IF EXISTS` se especifica una cláusula, la consulta no devolverá un error si la columna no existe.
-
-Cada columna puede tener un comentario. Si ya existe un comentario para la columna, un nuevo comentario sobrescribe el comentario anterior.
-
-Los comentarios se almacenan en el `comment_expression` columna devuelta por el [DESCRIBE TABLE](misc.md#misc-describe-table) consulta.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits COMMENT COLUMN browser 'The table shows the browser used for accessing the site.'
-```
-
-#### MODIFY COLUMN {#alter_modify-column}
-
-``` sql
-MODIFY COLUMN [IF EXISTS] name [type] [default_expr] [TTL]
-```
-
-Esta consulta cambia el `name` propiedades de la columna:
-
--   Tipo
-
--   Expresión predeterminada
-
--   TTL
-
-        For examples of columns TTL modifying, see [Column TTL](../engines/table_engines/mergetree_family/mergetree.md#mergetree-column-ttl).
-
-Si el `IF EXISTS` se especifica una cláusula, la consulta no devolverá un error si la columna no existe.
-
-Al cambiar el tipo, los valores se convierten como si [ToType](../../sql-reference/functions/type-conversion-functions.md) se les aplicaron funciones. Si solo se cambia la expresión predeterminada, la consulta no hace nada complejo y se completa casi al instante.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits MODIFY COLUMN browser Array(String)
-```
-
-Changing the column type is the only complex action – it changes the contents of files with data. For large tables, this may take a long time.
-
-Hay varias etapas de procesamiento:
-
--   Preparación de archivos temporales (nuevos) con datos modificados.
--   Cambiar el nombre de los archivos antiguos.
--   Cambiar el nombre de los archivos temporales (nuevos) a los nombres antiguos.
--   Eliminar los archivos antiguos.
-
-Solo la primera etapa lleva tiempo. Si hay un error en esta etapa, los datos no se cambian.
-Si hay un error durante una de las etapas sucesivas, los datos se pueden restaurar manualmente. La excepción es si los archivos antiguos se eliminaron del sistema de archivos, pero los datos de los nuevos archivos no se escribieron en el disco y se perdieron.
-
-El `ALTER` se replica la consulta para cambiar columnas. Las instrucciones se guardan en ZooKeeper, luego cada réplica las aplica. Todo `ALTER` las consultas se ejecutan en el mismo orden. La consulta espera a que se completen las acciones adecuadas en las otras réplicas. Sin embargo, una consulta para cambiar columnas en una tabla replicada se puede interrumpir y todas las acciones se realizarán de forma asincrónica.
-
-#### Limitaciones de consulta ALTER {#alter-query-limitations}
-
-El `ALTER` query le permite crear y eliminar elementos separados (columnas) en estructuras de datos anidadas, pero no en estructuras de datos anidadas completas. Para agregar una estructura de datos anidada, puede agregar columnas con un nombre como `name.nested_name` y el tipo `Array(T)`. Una estructura de datos anidada es equivalente a varias columnas de matriz con un nombre que tiene el mismo prefijo antes del punto.
-
-No hay soporte para eliminar columnas en la clave principal o la clave de muestreo (columnas que se utilizan en el `ENGINE` expresion). Solo es posible cambiar el tipo de las columnas que se incluyen en la clave principal si este cambio no provoca que se modifiquen los datos (por ejemplo, puede agregar valores a un Enum o cambiar un tipo de `DateTime` a `UInt32`).
-
-Si el `ALTER` la consulta no es suficiente para realizar los cambios en la tabla que necesita, puede crear una nueva tabla, copiar los datos [INSERT SELECT](insert-into.md#insert_query_insert-select) consulta, luego cambie las tablas usando el [RENAME](misc.md#misc_operations-rename) consulta y elimina la tabla anterior. Puede usar el [Método de codificación de datos:](../../operations/utilities/clickhouse-copier.md) como una alternativa a la `INSERT SELECT` consulta.
-
-El `ALTER` query bloquea todas las lecturas y escrituras para la tabla. En otras palabras, si un largo `SELECT` se está ejecutando en el momento de la `ALTER` consulta, el `ALTER` la consulta esperará a que se complete. Al mismo tiempo, todas las consultas nuevas a la misma tabla esperarán `ALTER` se está ejecutando.
-
-Para tablas que no almacenan datos por sí mismas (como `Merge` y `Distributed`), `ALTER` simplemente cambia la estructura de la tabla, y no cambia la estructura de las tablas subordinadas. Por ejemplo, cuando se ejecuta ALTER para un `Distributed` mesa, también tendrá que ejecutar `ALTER` para las tablas en todos los servidores remotos.
-
-### Manipulaciones con expresiones clave {#manipulations-with-key-expressions}
-
-Se admite el siguiente comando:
-
-``` sql
-MODIFY ORDER BY new_expression
-```
-
-Solo funciona para tablas en el [`MergeTree`](../../engines/table-engines/mergetree-family/mergetree.md) familia (incluyendo
-[repetición](../../engines/table-engines/mergetree-family/replication.md) tabla). El comando cambia el
-[clave de clasificación](../../engines/table-engines/mergetree-family/mergetree.md) de la mesa
-a `new_expression` (una expresión o una tupla de expresiones). La clave principal sigue siendo la misma.
-
-El comando es liviano en el sentido de que solo cambia los metadatos. Para mantener la propiedad esa parte de datos
-las filas están ordenadas por la expresión de clave de ordenación, no puede agregar expresiones que contengan columnas existentes
-a la clave de ordenación (sólo las columnas añadidas `ADD COLUMN` comando en el mismo `ALTER` consulta).
-
-### Manipulaciones con índices de saltos de datos {#manipulations-with-data-skipping-indices}
-
-Solo funciona para tablas en el [`*MergeTree`](../../engines/table-engines/mergetree-family/mergetree.md) familia (incluyendo
-[repetición](../../engines/table-engines/mergetree-family/replication.md) tabla). Las siguientes operaciones
-están disponibles:
-
--   `ALTER TABLE [db].name ADD INDEX name expression TYPE type GRANULARITY value AFTER name [AFTER name2]` - Agrega la descripción del índice a los metadatos de las tablas.
-
--   `ALTER TABLE [db].name DROP INDEX name` - Elimina la descripción del índice de los metadatos de las tablas y elimina los archivos de índice del disco.
-
-Estos comandos son livianos en el sentido de que solo cambian los metadatos o eliminan archivos.
-Además, se replican (sincronizando metadatos de índices a través de ZooKeeper).
-
-### Manipulaciones con restricciones {#manipulations-with-constraints}
-
-Ver más en [limitación](create.md#constraints)
-
-Las restricciones se pueden agregar o eliminar utilizando la siguiente sintaxis:
-
-``` sql
-ALTER TABLE [db].name ADD CONSTRAINT constraint_name CHECK expression;
-ALTER TABLE [db].name DROP CONSTRAINT constraint_name;
-```
-
-Las consultas agregarán o eliminarán metadatos sobre restricciones de la tabla para que se procesen inmediatamente.
-
-Comprobación de restricciones *no se ejecutará* en los datos existentes si se agregaron.
-
-Todos los cambios en las tablas replicadas se transmiten a ZooKeeper, por lo que se aplicarán en otras réplicas.
-
-### Manipulaciones con particiones y piezas {#alter_manipulations-with-partitions}
-
-Las siguientes operaciones con [partición](../../engines/table-engines/mergetree-family/custom-partitioning-key.md) están disponibles:
-
--   [DETACH PARTITION](#alter_detach-partition) – Moves a partition to the `detached` directorio y olvidarlo.
--   [DROP PARTITION](#alter_drop-partition) – Deletes a partition.
--   [ATTACH PART\|PARTITION](#alter_attach-partition) – Adds a part or partition from the `detached` directorio a la tabla.
--   [ATTACH PARTITION FROM](#alter_attach-partition-from) – Copies the data partition from one table to another and adds.
--   [REPLACE PARTITION](#alter_replace-partition) - Copia la partición de datos de una tabla a otra y reemplaza.
--   [MOVE PARTITION TO TABLE](#alter_move_to_table-partition)(#alter_move_to_table-partition) - Mover la partición de datos de una tabla a otra.
--   [CLEAR COLUMN IN PARTITION](#alter_clear-column-partition) - Restablece el valor de una columna especificada en una partición.
--   [CLEAR INDEX IN PARTITION](#alter_clear-index-partition) - Restablece el índice secundario especificado en una partición.
--   [FREEZE PARTITION](#alter_freeze-partition) – Creates a backup of a partition.
--   [FETCH PARTITION](#alter_fetch-partition) – Downloads a partition from another server.
--   [MOVE PARTITION\|PART](#alter_move-partition) – Move partition/data part to another disk or volume.
-
-<!-- -->
-
-#### DETACH PARTITION {#alter_detach-partition}
-
-``` sql
-ALTER TABLE table_name DETACH PARTITION partition_expr
-```
-
-Mueve todos los datos de la partición especificada `detached` directorio. El servidor se olvida de la partición de datos separada como si no existiera. El servidor no sabrá acerca de estos datos hasta que [ATTACH](#alter_attach-partition) consulta.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits DETACH PARTITION 201901
-```
-
-Lea cómo configurar la expresión de partición en una sección [Cómo especificar la expresión de partición](#alter-how-to-specify-part-expr).
-
-Después de ejecutar la consulta, puede hacer lo que quiera con los datos en el `detached` directory — delete it from the file system, or just leave it.
-
-This query is replicated – it moves the data to the `detached` directorio en todas las réplicas. Tenga en cuenta que solo puede ejecutar esta consulta en una réplica de líder. Para averiguar si una réplica es un líder, realice `SELECT` consulta a la [sistema.Replica](../../operations/system-tables.md#system_tables-replicas) tabla. Alternativamente, es más fácil hacer un `DETACH` consulta en todas las réplicas: todas las réplicas producen una excepción, excepto la réplica líder.
-
-#### DROP PARTITION {#alter_drop-partition}
-
-``` sql
-ALTER TABLE table_name DROP PARTITION partition_expr
-```
-
-Elimina la partición especificada de la tabla. Esta consulta etiqueta la partición como inactiva y elimina los datos por completo, aproximadamente en 10 minutos.
-
-Lea cómo configurar la expresión de partición en una sección [Cómo especificar la expresión de partición](#alter-how-to-specify-part-expr).
-
-The query is replicated – it deletes data on all replicas.
-
-#### DROP DETACHED PARTITION\|PART {#alter_drop-detached}
-
-``` sql
-ALTER TABLE table_name DROP DETACHED PARTITION|PART partition_expr
-```
-
-Quita la parte especificada o todas las partes de la partición especificada de `detached`.
-Más información sobre cómo establecer la expresión de partición en una sección [Cómo especificar la expresión de partición](#alter-how-to-specify-part-expr).
-
-#### ATTACH PARTITION\|PART {#alter_attach-partition}
-
-``` sql
-ALTER TABLE table_name ATTACH PARTITION|PART partition_expr
-```
-
-Agrega datos a la tabla desde el `detached` directorio. Es posible agregar datos para una partición completa o para una parte separada. Ejemplos:
-
-``` sql
-ALTER TABLE visits ATTACH PARTITION 201901;
-ALTER TABLE visits ATTACH PART 201901_2_2_0;
-```
-
-Más información sobre cómo establecer la expresión de partición en una sección [Cómo especificar la expresión de partición](#alter-how-to-specify-part-expr).
-
-Esta consulta se replica. El iniciador de réplica comprueba si hay datos en el `detached` directorio. Si existen datos, la consulta comprueba su integridad. Si todo es correcto, la consulta agrega los datos a la tabla. Todas las demás réplicas descargan los datos del iniciador de réplica.
-
-Entonces puedes poner datos en el `detached` en una réplica, y utilice el directorio `ALTER ... ATTACH` consulta para agregarlo a la tabla en todas las réplicas.
-
-#### ATTACH PARTITION FROM {#alter_attach-partition-from}
-
-``` sql
-ALTER TABLE table2 ATTACH PARTITION partition_expr FROM table1
-```
-
-Esta consulta copia la partición de datos `table1` a `table2` añade datos a los que existen en el `table2`. Tenga en cuenta que los datos no se eliminarán de `table1`.
-
-Para que la consulta se ejecute correctamente, se deben cumplir las siguientes condiciones:
-
--   Ambas tablas deben tener la misma estructura.
--   Ambas tablas deben tener la misma clave de partición.
-
-#### REPLACE PARTITION {#alter_replace-partition}
-
-``` sql
-ALTER TABLE table2 REPLACE PARTITION partition_expr FROM table1
-```
-
-Esta consulta copia la partición de datos `table1` a `table2` y reemplaza la partición existente en el `table2`. Tenga en cuenta que los datos no se eliminarán de `table1`.
-
-Para que la consulta se ejecute correctamente, se deben cumplir las siguientes condiciones:
-
--   Ambas tablas deben tener la misma estructura.
--   Ambas tablas deben tener la misma clave de partición.
-
-#### MOVE PARTITION TO TABLE {#alter_move_to_table-partition}
-
-``` sql
-ALTER TABLE table_source MOVE PARTITION partition_expr TO TABLE table_dest
-```
-
-Esta consulta mueve la partición de datos `table_source` a `table_dest` con la eliminación de los datos de `table_source`.
-
-Para que la consulta se ejecute correctamente, se deben cumplir las siguientes condiciones:
-
--   Ambas tablas deben tener la misma estructura.
--   Ambas tablas deben tener la misma clave de partición.
--   Ambas tablas deben ser de la misma familia de motores. (replicado o no replicado)
--   Ambas tablas deben tener la misma política de almacenamiento.
-
-#### CLEAR COLUMN IN PARTITION {#alter_clear-column-partition}
-
-``` sql
-ALTER TABLE table_name CLEAR COLUMN column_name IN PARTITION partition_expr
-```
-
-Restablece todos los valores de la columna especificada en una partición. Si el `DEFAULT` cláusula se determinó al crear una tabla, esta consulta establece el valor de columna en un valor predeterminado especificado.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE visits CLEAR COLUMN hour in PARTITION 201902
-```
-
-#### FREEZE PARTITION {#alter_freeze-partition}
-
-``` sql
-ALTER TABLE table_name FREEZE [PARTITION partition_expr]
-```
-
-Esta consulta crea una copia de seguridad local de una partición especificada. Si el `PARTITION` se omite la cláusula, la consulta crea la copia de seguridad de todas las particiones a la vez.
-
-!!! note "Nota"
-    Todo el proceso de copia de seguridad se realiza sin detener el servidor.
-
-Tenga en cuenta que para las tablas de estilo antiguo puede especificar el prefijo del nombre de la partición (por ejemplo, ‘2019’) - entonces la consulta crea la copia de seguridad para todas las particiones correspondientes. Lea cómo configurar la expresión de partición en una sección [Cómo especificar la expresión de partición](#alter-how-to-specify-part-expr).
-
-En el momento de la ejecución, para una instantánea de datos, la consulta crea vínculos rígidos a los datos de una tabla. Los enlaces duros se colocan en el directorio `/var/lib/clickhouse/shadow/N/...`, donde:
-
--   `/var/lib/clickhouse/` es el directorio ClickHouse de trabajo especificado en la configuración.
--   `N` es el número incremental de la copia de seguridad.
-
-!!! note "Nota"
-    Si usted usa [un conjunto de discos para el almacenamiento de datos en una tabla](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes), el `shadow/N` directorio aparece en cada disco, almacenando partes de datos que coinciden con el `PARTITION` expresion.
-
-La misma estructura de directorios se crea dentro de la copia de seguridad que dentro `/var/lib/clickhouse/`. La consulta realiza ‘chmod’ para todos los archivos, prohibiendo escribir en ellos.
-
-Después de crear la copia de seguridad, puede copiar los datos desde `/var/lib/clickhouse/shadow/` al servidor remoto y, a continuación, elimínelo del servidor local. Tenga en cuenta que el `ALTER t FREEZE PARTITION` consulta no se replica. Crea una copia de seguridad local solo en el servidor local.
-
-La consulta crea una copia de seguridad casi instantáneamente (pero primero espera a que las consultas actuales a la tabla correspondiente terminen de ejecutarse).
-
-`ALTER TABLE t FREEZE PARTITION` copia solo los datos, no los metadatos de la tabla. Para hacer una copia de seguridad de los metadatos de la tabla, copie el archivo `/var/lib/clickhouse/metadata/database/table.sql`
-
-Para restaurar los datos de una copia de seguridad, haga lo siguiente:
-
-1.  Cree la tabla si no existe. Para ver la consulta, utilice el .archivo sql (reemplazar `ATTACH` en ella con `CREATE`).
-2.  Copie los datos de la `data/database/table/` directorio dentro de la copia de seguridad a la `/var/lib/clickhouse/data/database/table/detached/` directorio.
-3.  Ejecutar `ALTER TABLE t ATTACH PARTITION` consultas para agregar los datos a una tabla.
-
-La restauración desde una copia de seguridad no requiere detener el servidor.
-
-Para obtener más información sobre las copias de seguridad y la restauración de datos, consulte [Copia de seguridad de datos](../../operations/backup.md) apartado.
-
-#### CLEAR INDEX IN PARTITION {#alter_clear-index-partition}
-
-``` sql
-ALTER TABLE table_name CLEAR INDEX index_name IN PARTITION partition_expr
-```
-
-La consulta funciona de forma similar a `CLEAR COLUMN`, pero restablece un índice en lugar de una columna de datos.
-
-#### FETCH PARTITION {#alter_fetch-partition}
-
-``` sql
-ALTER TABLE table_name FETCH PARTITION partition_expr FROM 'path-in-zookeeper'
-```
-
-Descarga una partición desde otro servidor. Esta consulta solo funciona para las tablas replicadas.
-
-La consulta hace lo siguiente:
-
-1.  Descarga la partición del fragmento especificado. En ‘path-in-zookeeper’ debe especificar una ruta al fragmento en ZooKeeper.
-2.  Luego, la consulta coloca los datos descargados en el `detached` directorio de la `table_name` tabla. Utilice el [ATTACH PARTITION\|PART](#alter_attach-partition) consulta para agregar los datos a la tabla.
-
-Por ejemplo:
-
-``` sql
-ALTER TABLE users FETCH PARTITION 201902 FROM '/clickhouse/tables/01-01/visits';
-ALTER TABLE users ATTACH PARTITION 201902;
-```
-
-Tenga en cuenta que:
-
--   El `ALTER ... FETCH PARTITION` consulta no se replica. Coloca la partición en el `detached` sólo en el servidor local.
--   El `ALTER TABLE ... ATTACH` consulta se replica. Agrega los datos a todas las réplicas. Los datos se agregan a una de las réplicas desde el `detached` directorio, y para los demás - de réplicas vecinas.
-
-Antes de descargar, el sistema verifica si la partición existe y la estructura de la tabla coincide. La réplica más adecuada se selecciona automáticamente de las réplicas en buen estado.
-
-Aunque se llama a la consulta `ALTER TABLE`, no cambia la estructura de la tabla y no cambiar inmediatamente los datos disponibles en la tabla.
-
-#### MOVE PARTITION\|PART {#alter_move-partition}
-
-Mueve particiones o partes de datos a otro volumen o disco para `MergeTree`-mesas de motor. Ver [Uso de varios dispositivos de bloque para el almacenamiento de datos](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes).
-
-``` sql
-ALTER TABLE table_name MOVE PARTITION|PART partition_expr TO DISK|VOLUME 'disk_name'
-```
-
-El `ALTER TABLE t MOVE` consulta:
-
--   No replicado, porque diferentes réplicas pueden tener diferentes directivas de almacenamiento.
--   Devuelve un error si el disco o volumen especificado no está configurado. La consulta también devuelve un error si no se pueden aplicar las condiciones de movimiento de datos especificadas en la directiva de almacenamiento.
--   Puede devolver un error en el caso, cuando los datos que se moverán ya se mueven por un proceso en segundo plano, concurrente `ALTER TABLE t MOVE` consulta o como resultado de la fusión de datos de fondo. Un usuario no debe realizar ninguna acción adicional en este caso.
-
-Ejemplo:
-
-``` sql
-ALTER TABLE hits MOVE PART '20190301_14343_16206_438' TO VOLUME 'slow'
-ALTER TABLE hits MOVE PARTITION '2019-09-01' TO DISK 'fast_ssd'
-```
-
-#### Cómo establecer la expresión de partición {#alter-how-to-specify-part-expr}
-
-Puede especificar la expresión de partición en `ALTER ... PARTITION` de diferentes maneras:
-
--   Como valor de la `partition` columna de la `system.parts` tabla. Por ejemplo, `ALTER TABLE visits DETACH PARTITION 201901`.
--   Como la expresión de la columna de la tabla. Se admiten constantes y expresiones constantes. Por ejemplo, `ALTER TABLE visits DETACH PARTITION toYYYYMM(toDate('2019-01-25'))`.
--   Usando el ID de partición. El ID de partición es un identificador de cadena de la partición (legible por humanos, si es posible) que se usa como nombres de particiones en el sistema de archivos y en ZooKeeper. El ID de partición debe especificarse en el `PARTITION ID` cláusula, entre comillas simples. Por ejemplo, `ALTER TABLE visits DETACH PARTITION ID '201901'`.
--   En el [ALTER ATTACH PART](#alter_attach-partition) y [DROP DETACHED PART](#alter_drop-detached) consulta, para especificar el nombre de una parte, utilice un literal de cadena con un valor `name` columna de la [sistema.detached_parts](../../operations/system-tables.md#system_tables-detached_parts) tabla. Por ejemplo, `ALTER TABLE visits ATTACH PART '201901_1_1_0'`.
-
-El uso de comillas al especificar la partición depende del tipo de expresión de partición. Por ejemplo, para el `String` tipo, debe especificar su nombre entre comillas (`'`). Para el `Date` y `Int*` tipos no se necesitan comillas.
-
-Para las tablas de estilo antiguo, puede especificar la partición como un número `201901` o una cadena `'201901'`. La sintaxis para las tablas de nuevo estilo es más estricta con los tipos (similar al analizador para el formato de entrada VALUES).
-
-Todas las reglas anteriores también son ciertas para el [OPTIMIZE](misc.md#misc_operations-optimize) consulta. Si necesita especificar la única partición al optimizar una tabla no particionada, establezca la expresión `PARTITION tuple()`. Por ejemplo:
-
-``` sql
-OPTIMIZE TABLE table_not_partitioned PARTITION tuple() FINAL;
-```
-
-Los ejemplos de `ALTER ... PARTITION` las consultas se demuestran en las pruebas [`00502_custom_partitioning_local`](https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/00502_custom_partitioning_local.sql) y [`00502_custom_partitioning_replicated_zookeeper`](https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/00502_custom_partitioning_replicated_zookeeper.sql).
-
-### Manipulaciones con Tabla TTL {#manipulations-with-table-ttl}
-
-Usted puede cambiar [tabla TTL](../../engines/table-engines/mergetree-family/mergetree.md#mergetree-table-ttl) con una solicitud del siguiente formulario:
-
-``` sql
-ALTER TABLE table-name MODIFY TTL ttl-expression
-```
-
-### Sincronicidad de las consultas ALTER {#synchronicity-of-alter-queries}
-
-Para tablas no replicables, todas `ALTER` las consultas se realizan de forma sincrónica. Para las tablas replicables, la consulta solo agrega instrucciones para las acciones apropiadas para `ZooKeeper`, y las acciones mismas se realizan tan pronto como sea posible. Sin embargo, la consulta puede esperar a que estas acciones se completen en todas las réplicas.
-
-Para `ALTER ... ATTACH|DETACH|DROP` consultas, puede utilizar el `replication_alter_partitions_sync` configuración para configurar la espera.
-Valores posibles: `0` – do not wait; `1` – only wait for own execution (default); `2` – wait for all.
-
-### Mutación {#alter-mutations}
-
-Las mutaciones son una variante de consulta ALTER que permite cambiar o eliminar filas en una tabla. En contraste con el estándar `UPDATE` y `DELETE` consultas destinadas a cambios de datos puntuales, las mutaciones están destinadas a operaciones pesadas que cambian muchas filas en una tabla. Apoyado para el `MergeTree` familia de motores de mesa, incluidos los motores con soporte de replicación.
-
-Las tablas existentes están listas para las mutaciones tal como están (no es necesaria la conversión), pero después de que la primera mutación se aplica a una tabla, su formato de metadatos se vuelve incompatible con las versiones anteriores del servidor y volver a una versión anterior se vuelve imposible.
-
-Comandos disponibles actualmente:
-
-``` sql
-ALTER TABLE [db.]table DELETE WHERE filter_expr
-```
-
-El `filter_expr` debe ser de tipo `UInt8`. La consulta elimina las filas de la tabla para la que esta expresión toma un valor distinto de cero.
-
-``` sql
-ALTER TABLE [db.]table UPDATE column1 = expr1 [, ...] WHERE filter_expr
-```
-
-El `filter_expr` debe ser de tipo `UInt8`. Esta consulta actualiza los valores de las columnas especificadas a los valores de las expresiones correspondientes `filter_expr` toma un valor distinto de cero. Los valores se convierten al tipo de columna utilizando el `CAST` operador. No se admite la actualización de columnas que se utilizan en el cálculo de la clave principal o de partición.
-
-``` sql
-ALTER TABLE [db.]table MATERIALIZE INDEX name IN PARTITION partition_name
-```
-
-La consulta reconstruye el índice secundario `name` en la partición `partition_name`.
-
-Una consulta puede contener varios comandos separados por comas.
-
-Para las tablas \*MergeTree, las mutaciones se ejecutan reescribiendo partes de datos completas. No hay atomicidad - las partes se sustituyen por partes mutadas tan pronto como están listas y una `SELECT` La consulta que comenzó a ejecutarse durante una mutación verá datos de partes que ya han sido mutadas junto con datos de partes que aún no han sido mutadas.
-
-Las mutaciones están totalmente ordenadas por su orden de creación y se aplican a cada parte en ese orden. Las mutaciones también se ordenan parcialmente con INSERTs: los datos que se insertaron en la tabla antes de que se enviara la mutación se mutarán y los datos que se insertaron después de eso no se mutarán. Tenga en cuenta que las mutaciones no bloquean INSERTs de ninguna manera.
-
-Una consulta de mutación regresa inmediatamente después de agregar la entrada de mutación (en el caso de tablas replicadas a ZooKeeper, para tablas no replicadas, al sistema de archivos). La mutación en sí se ejecuta de forma asíncrona utilizando la configuración del perfil del sistema. Para realizar un seguimiento del progreso de las mutaciones, puede usar el [`system.mutations`](../../operations/system-tables.md#system_tables-mutations) tabla. Una mutación que se envió correctamente continuará ejecutándose incluso si se reinician los servidores ClickHouse. No hay forma de revertir la mutación una vez que se presenta, pero si la mutación está atascada por alguna razón, puede cancelarse con el [`KILL MUTATION`](misc.md#kill-mutation) consulta.
-
-Las entradas de mutaciones terminadas no se eliminan de inmediato (el número de entradas conservadas viene determinado por el `finished_mutations_to_keep` parámetro del motor de almacenamiento). Las entradas de mutación más antiguas se eliminan.

-# CREATE Consultas {#create-queries}
-
-## CREATE DATABASE {#query-language-create-database}
-
-Crea una base de datos.
-
-``` sql
-CREATE DATABASE [IF NOT EXISTS] db_name [ON CLUSTER cluster] [ENGINE = engine(...)]
-```
-
-### Clausula {#clauses}
-
--   `IF NOT EXISTS`
-    Si el `db_name` base de datos ya existe, entonces ClickHouse no crea una nueva base de datos y:
-
-    -   No lanza una excepción si se especifica una cláusula.
-    -   Lanza una excepción si no se especifica la cláusula.
-
--   `ON CLUSTER`
-    ClickHouse crea el `db_name` base de datos en todos los servidores de un clúster especificado.
-
--   `ENGINE`
-
-    -   [MySQL](../../engines/database-engines/mysql.md)
-        Le permite recuperar datos del servidor MySQL remoto.
-        De forma predeterminada, ClickHouse usa su propio [motor de base de datos](../../engines/database-engines/index.md).
-
-## CREATE TABLE {#create-table-query}
-
-El `CREATE TABLE` consulta puede tener varias formas.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [compression_codec] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [compression_codec] [TTL expr2],
-    ...
-) ENGINE = engine
-```
-
-Crea una tabla llamada ‘name’ en el ‘db’ base de datos o la base de datos actual si ‘db’ no está establecida, con la estructura especificada entre paréntesis y ‘engine’ motor.
-La estructura de la tabla es una lista de descripciones de columnas. Si los índices son compatibles con el motor, se indican como parámetros para el motor de tablas.
-
-Una descripción de columna es `name type` en el caso más simple. Ejemplo: `RegionID UInt32`.
-Las expresiones también se pueden definir para los valores predeterminados (ver más abajo).
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name AS [db2.]name2 [ENGINE = engine]
-```
-
-Crea una tabla con la misma estructura que otra tabla. Puede especificar un motor diferente para la tabla. Si no se especifica el motor, se utilizará el mismo motor que para el `db2.name2` tabla.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name AS table_function()
-```
-
-Crea una tabla con la estructura y los datos [función de la tabla](../table-functions/index.md#table-functions).
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name ENGINE = engine AS SELECT ...
-```
-
-Crea una tabla con una estructura como el resultado de la `SELECT` consulta, con el ‘engine’ motor, y lo llena con datos de SELECT.
-
-En todos los casos, si `IF NOT EXISTS` se especifica, la consulta no devolverá un error si la tabla ya existe. En este caso, la consulta no hará nada.
-
-Puede haber otras cláusulas después del `ENGINE` cláusula en la consulta. Consulte la documentación detallada sobre cómo crear tablas en las descripciones de [motores de mesa](../../engines/table-engines/index.md#table_engines).
-
-### Valores predeterminados {#create-default-values}
-
-La descripción de la columna puede especificar una expresión para un valor predeterminado, de una de las siguientes maneras:`DEFAULT expr`, `MATERIALIZED expr`, `ALIAS expr`.
-Ejemplo: `URLDomain String DEFAULT domain(URL)`.
-
-Si no se define una expresión para el valor predeterminado, los valores predeterminados se establecerán en ceros para números, cadenas vacías para cadenas, matrices vacías para matrices y `1970-01-01` para fechas o zero unix timestamp para las fechas con el tiempo. Los NULL no son compatibles.
-
-Si se define la expresión predeterminada, el tipo de columna es opcional. Si no hay un tipo definido explícitamente, se utiliza el tipo de expresión predeterminado. Ejemplo: `EventDate DEFAULT toDate(EventTime)` – the ‘Date’ tipo será utilizado para el ‘EventDate’ columna.
-
-Si el tipo de datos y la expresión predeterminada se definen explícitamente, esta expresión se convertirá al tipo especificado utilizando funciones de conversión de tipos. Ejemplo: `Hits UInt32 DEFAULT 0` significa lo mismo que `Hits UInt32 DEFAULT toUInt32(0)`.
-
-Default expressions may be defined as an arbitrary expression from table constants and columns. When creating and changing the table structure, it checks that expressions don't contain loops. For INSERT, it checks that expressions are resolvable – that all columns they can be calculated from have been passed.
-
-`DEFAULT expr`
-
-Valor predeterminado Normal. Si la consulta INSERT no especifica la columna correspondiente, se completará calculando la expresión correspondiente.
-
-`MATERIALIZED expr`
-
-Expresión materializada. Dicha columna no se puede especificar para INSERT, porque siempre se calcula.
-Para un INSERT sin una lista de columnas, estas columnas no se consideran.
-Además, esta columna no se sustituye cuando se utiliza un asterisco en una consulta SELECT. Esto es para preservar el invariante que el volcado obtuvo usando `SELECT *` se puede volver a insertar en la tabla usando INSERT sin especificar la lista de columnas.
-
-`ALIAS expr`
-
-Sinónimo. Tal columna no se almacena en la tabla en absoluto.
-Sus valores no se pueden insertar en una tabla, y no se sustituye cuando se usa un asterisco en una consulta SELECT.
-Se puede usar en SELECT si el alias se expande durante el análisis de consultas.
-
-Cuando se utiliza la consulta ALTER para agregar nuevas columnas, no se escriben datos antiguos para estas columnas. En su lugar, al leer datos antiguos que no tienen valores para las nuevas columnas, las expresiones se calculan sobre la marcha de forma predeterminada. Sin embargo, si la ejecución de las expresiones requiere diferentes columnas que no están indicadas en la consulta, estas columnas se leerán adicionalmente, pero solo para los bloques de datos que lo necesitan.
-
-Si agrega una nueva columna a una tabla pero luego cambia su expresión predeterminada, los valores utilizados para los datos antiguos cambiarán (para los datos donde los valores no se almacenaron en el disco). Tenga en cuenta que cuando se ejecutan combinaciones en segundo plano, los datos de las columnas que faltan en una de las partes de combinación se escriben en la parte combinada.
-
-No es posible establecer valores predeterminados para elementos en estructuras de datos anidadas.
-
-### Limitación {#constraints}
-
-Junto con las descripciones de columnas, se podrían definir restricciones:
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [compression_codec] [TTL expr1],
-    ...
-    CONSTRAINT constraint_name_1 CHECK boolean_expr_1,
-    ...
-) ENGINE = engine
-```
-
-`boolean_expr_1` podría por cualquier expresión booleana. Si se definen restricciones para la tabla, cada una de ellas se verificará para cada fila en `INSERT` query. If any constraint is not satisfied — server will raise an exception with constraint name and checking expression.
-
-Agregar una gran cantidad de restricciones puede afectar negativamente el rendimiento de grandes `INSERT` consulta.
-
-### Expresión TTL {#ttl-expression}
-
-Define el tiempo de almacenamiento de los valores. Solo se puede especificar para tablas de la familia MergeTree. Para la descripción detallada, ver [TTL para columnas y tablas](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-ttl).
-
-### Códecs de compresión de columna {#codecs}
-
-De forma predeterminada, ClickHouse aplica el `lz4` método de compresión. Para `MergeTree`- familia de motor puede cambiar el método de compresión predeterminado en el [compresión](../../operations/server-configuration-parameters/settings.md#server-settings-compression) sección de una configuración de servidor. También puede definir el método de compresión para cada columna `CREATE TABLE` consulta.
-
-``` sql
-CREATE TABLE codec_example
-(
-    dt Date CODEC(ZSTD),
-    ts DateTime CODEC(LZ4HC),
-    float_value Float32 CODEC(NONE),
-    double_value Float64 CODEC(LZ4HC(9))
-    value Float32 CODEC(Delta, ZSTD)
-)
-ENGINE = <Engine>
-...
-```
-
-Si se especifica un códec, el códec predeterminado no se aplica. Los códecs se pueden combinar en una tubería, por ejemplo, `CODEC(Delta, ZSTD)`. Para seleccionar la mejor combinación de códecs para su proyecto, pase puntos de referencia similares a los descritos en Altinity [Nuevas codificaciones para mejorar la eficiencia de ClickHouse](https://www.altinity.com/blog/2019/7/new-encodings-to-improve-clickhouse) artículo.
-
-!!! warning "Advertencia"
-    No puede descomprimir archivos de base de datos ClickHouse con utilidades externas como `lz4`. En su lugar, use el especial [Compresor de clickhouse](https://github.com/ClickHouse/ClickHouse/tree/master/programs/compressor) utilidad.
-
-La compresión es compatible con los siguientes motores de tablas:
-
--   [Método de codificación de datos:](../../engines/table-engines/mergetree-family/mergetree.md) familia. Admite códecs de compresión de columnas y selecciona el método de compresión predeterminado mediante [compresión](../../operations/server-configuration-parameters/settings.md#server-settings-compression) configuración.
--   [Registro](../../engines/table-engines/log-family/index.md) familia. Utiliza el `lz4` método de compresión por defecto y soporta códecs de compresión de columna.
--   [Establecer](../../engines/table-engines/special/set.md). Solo admite la compresión predeterminada.
--   [Unir](../../engines/table-engines/special/join.md). Solo admite la compresión predeterminada.
-
-ClickHouse admite códecs de propósito común y códecs especializados.
-
-#### Especializados Codecs {#create-query-specialized-codecs}
-
-Estos códecs están diseñados para hacer que la compresión sea más efectiva mediante el uso de características específicas de los datos. Algunos de estos códecs no comprimen los datos por sí mismos. En su lugar, preparan los datos para un códec de propósito común, que lo comprime mejor que sin esta preparación.
-
-Especializados codecs:
-
--   `Delta(delta_bytes)` — Compression approach in which raw values are replaced by the difference of two neighboring values, except for the first value that stays unchanged. Up to `delta_bytes` se utilizan para almacenar valores delta, por lo que `delta_bytes` es el tamaño máximo de los valores brutos. Posible `delta_bytes` valores: 1, 2, 4, 8. El valor predeterminado para `delta_bytes` ser `sizeof(type)` si es igual a 1, 2, 4 u 8. En todos los demás casos, es 1.
--   `DoubleDelta` — Calculates delta of deltas and writes it in compact binary form. Optimal compression rates are achieved for monotonic sequences with a constant stride, such as time series data. Can be used with any fixed-width type. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. Uses 1 extra bit for 32-byte deltas: 5-bit prefixes instead of 4-bit prefixes. For additional information, see Compressing Time Stamps in [Gorila: Una base de datos de series temporales rápida, escalable y en memoria](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
--   `Gorilla` — Calculates XOR between current and previous value and writes it in compact binary form. Efficient when storing a series of floating point values that change slowly, because the best compression rate is achieved when neighboring values are binary equal. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. For additional information, see Compressing Values in [Gorila: Una base de datos de series temporales rápida, escalable y en memoria](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
--   `T64` — Compression approach that crops unused high bits of values in integer data types (including `Enum`, `Date` y `DateTime`). En cada paso de su algoritmo, el códec toma un bloque de 64 valores, los coloca en una matriz de 64x64 bits, lo transpone, recorta los bits de valores no utilizados y devuelve el resto como una secuencia. Los bits no utilizados son los bits, que no difieren entre los valores máximo y mínimo en toda la parte de datos para la que se utiliza la compresión.
-
-`DoubleDelta` y `Gorilla` códecs se utilizan en Gorilla TSDB como los componentes de su algoritmo de compresión. El enfoque de gorila es efectivo en escenarios en los que hay una secuencia de valores que cambian lentamente con sus marcas de tiempo. Las marcas de tiempo se comprimen efectivamente por el `DoubleDelta` códec, y los valores son efectivamente comprimidos por el `Gorilla` códec. Por ejemplo, para obtener una tabla almacenada efectivamente, puede crearla en la siguiente configuración:
-
-``` sql
-CREATE TABLE codec_example
-(
-    timestamp DateTime CODEC(DoubleDelta),
-    slow_values Float32 CODEC(Gorilla)
-)
-ENGINE = MergeTree()
-```
-
-#### Códecs de uso general {#create-query-general-purpose-codecs}
-
-Códecs:
-
--   `NONE` — No compression.
--   `LZ4` — Lossless [algoritmo de compresión de datos](https://github.com/lz4/lz4) utilizado por defecto. Aplica compresión rápida LZ4.
--   `LZ4HC[(level)]` — LZ4 HC (high compression) algorithm with configurable level. Default level: 9. Setting `level <= 0` aplica el nivel predeterminado. Niveles posibles: \[1, 12\]. Rango de nivel recomendado: \[4, 9\].
--   `ZSTD[(level)]` — [Algoritmo de compresión ZSTD](https://en.wikipedia.org/wiki/Zstandard) con configurable `level`. Niveles posibles: \[1, 22\]. Valor predeterminado: 1.
-
-Los altos niveles de compresión son útiles para escenarios asimétricos, como comprimir una vez, descomprimir repetidamente. Los niveles más altos significan una mejor compresión y un mayor uso de la CPU.
-
-## Tablas temporales {#temporary-tables}
-
-ClickHouse admite tablas temporales que tienen las siguientes características:
-
--   Las tablas temporales desaparecen cuando finaliza la sesión, incluso si se pierde la conexión.
--   Una tabla temporal solo utiliza el motor de memoria.
--   No se puede especificar la base de datos para una tabla temporal. Se crea fuera de las bases de datos.
--   Imposible crear una tabla temporal con consulta DDL distribuida en todos los servidores de clúster (mediante `ON CLUSTER`): esta tabla sólo existe en la sesión actual.
--   Si una tabla temporal tiene el mismo nombre que otra y una consulta especifica el nombre de la tabla sin especificar la base de datos, se utilizará la tabla temporal.
--   Para el procesamiento de consultas distribuidas, las tablas temporales utilizadas en una consulta se pasan a servidores remotos.
-
-Para crear una tabla temporal, utilice la siguiente sintaxis:
-
-``` sql
-CREATE TEMPORARY TABLE [IF NOT EXISTS] table_name
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-)
-```
-
-En la mayoría de los casos, las tablas temporales no se crean manualmente, sino cuando se utilizan datos externos para una consulta o para `(GLOBAL) IN`. Para obtener más información, consulte las secciones correspondientes
-
-Es posible usar tablas con [MOTOR = Memoria](../../engines/table-engines/special/memory.md) en lugar de tablas temporales.
-
-## Consultas DDL distribuidas (cláusula ON CLUSTER) {#distributed-ddl-queries-on-cluster-clause}
-
-El `CREATE`, `DROP`, `ALTER`, y `RENAME` las consultas admiten la ejecución distribuida en un clúster.
-Por ejemplo, la siguiente consulta crea el `all_hits` `Distributed` la tabla en cada host `cluster`:
-
-``` sql
-CREATE TABLE IF NOT EXISTS all_hits ON CLUSTER cluster (p Date, i Int32) ENGINE = Distributed(cluster, default, hits)
-```
-
-Para ejecutar estas consultas correctamente, cada host debe tener la misma definición de clúster (para simplificar la sincronización de configuraciones, puede usar sustituciones de ZooKeeper). También deben conectarse a los servidores ZooKeeper.
-La versión local de la consulta finalmente se implementará en cada host del clúster, incluso si algunos hosts no están disponibles actualmente. El orden para ejecutar consultas dentro de un único host está garantizado.
-
-## CREATE VIEW {#create-view}
-
-``` sql
-CREATE [MATERIALIZED] VIEW [IF NOT EXISTS] [db.]table_name [TO[db.]name] [ENGINE = engine] [POPULATE] AS SELECT ...
-```
-
-Crea una vista. Hay dos tipos de vistas: normal y MATERIALIZADO.
-
-Las vistas normales no almacenan ningún dato, solo realizan una lectura desde otra tabla. En otras palabras, una vista normal no es más que una consulta guardada. Al leer desde una vista, esta consulta guardada se utiliza como una subconsulta en la cláusula FROM.
-
-Como ejemplo, suponga que ha creado una vista:
-
-``` sql
-CREATE VIEW view AS SELECT ...
-```
-
-y escribió una consulta:
-
-``` sql
-SELECT a, b, c FROM view
-```
-
-Esta consulta es totalmente equivalente a usar la subconsulta:
-
-``` sql
-SELECT a, b, c FROM (SELECT ...)
-```
-
-Las vistas materializadas almacenan datos transformados por la consulta SELECT correspondiente.
-
-Al crear una vista materializada sin `TO [db].[table]`, you must specify ENGINE – the table engine for storing data.
-
-Al crear una vista materializada con `TO [db].[table]` usted no debe usar `POPULATE`.
-
-Una vista materializada se organiza de la siguiente manera: al insertar datos en la tabla especificada en SELECT, parte de los datos insertados se convierte mediante esta consulta SELECT y el resultado se inserta en la vista.
-
-Si especifica POPULATE, los datos de tabla existentes se insertan en la vista al crearlos, como si `CREATE TABLE ... AS SELECT ...` . De lo contrario, la consulta solo contiene los datos insertados en la tabla después de crear la vista. No recomendamos usar POPULATE, ya que los datos insertados en la tabla durante la creación de la vista no se insertarán en ella.
-
-A `SELECT` consulta puede contener `DISTINCT`, `GROUP BY`, `ORDER BY`, `LIMIT`… Note that the corresponding conversions are performed independently on each block of inserted data. For example, if `GROUP BY` se establece, los datos se agregan durante la inserción, pero solo dentro de un solo paquete de datos insertados. Los datos no se agregarán más. La excepción es cuando se utiliza un ENGINE que realiza de forma independiente la agregación de datos, como `SummingMergeTree`.
-
-La ejecución de `ALTER` las consultas sobre vistas materializadas no se han desarrollado completamente, por lo que podrían ser inconvenientes. Si la vista materializada utiliza la construcción `TO [db.]name` puede `DETACH` la vista, ejecutar `ALTER` para la tabla de destino, y luego `ATTACH` el previamente separado (`DETACH`) vista.
-
-Las vistas tienen el mismo aspecto que las tablas normales. Por ejemplo, se enumeran en el resultado de la `SHOW TABLES` consulta.
-
-No hay una consulta separada para eliminar vistas. Para eliminar una vista, utilice `DROP TABLE`.

-
-Crear [diccionario externo](../../sql-reference/dictionaries/external-dictionaries/external-dicts.md) con dado [estructura](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-structure.md), [fuente](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-sources.md), [diseño](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-layout.md) y [vida](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-lifetime.md).
-
-La estructura del diccionario externo consta de atributos. Los atributos de diccionario se especifican de manera similar a las columnas de la tabla. La única propiedad de atributo requerida es su tipo, todas las demás propiedades pueden tener valores predeterminados.
-
-Dependiendo del diccionario [diseño](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-layout.md) se pueden especificar uno o más atributos como claves de diccionario.
-
-Para obtener más información, consulte [Diccionarios externos](../dictionaries/external-dictionaries/external-dicts.md) apartado.
-
-## CREATE USER {#create-user-statement}
-
-Crea un [cuenta de usuario](../../operations/access-rights.md#user-account-management).
-
-### Sintaxis {#create-user-syntax}
-
-``` sql
-CREATE USER [IF NOT EXISTS | OR REPLACE] name [ON CLUSTER cluster_name]
-    [IDENTIFIED [WITH {NO_PASSWORD|PLAINTEXT_PASSWORD|SHA256_PASSWORD|SHA256_HASH|DOUBLE_SHA1_PASSWORD|DOUBLE_SHA1_HASH}] BY {'password'|'hash'}]
-    [HOST {LOCAL | NAME 'name' | REGEXP 'name_regexp' | IP 'address' | LIKE 'pattern'} [,...] | ANY | NONE]
-    [DEFAULT ROLE role [,...]]
-    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [READONLY|WRITABLE] | PROFILE 'profile_name'] [,...]
-```
-
-#### Identificación {#identification}
-
-Hay múltiples formas de identificación del usuario:
-
--   `IDENTIFIED WITH no_password`
--   `IDENTIFIED WITH plaintext_password BY 'qwerty'`
--   `IDENTIFIED WITH sha256_password BY 'qwerty'` o `IDENTIFIED BY 'password'`
--   `IDENTIFIED WITH sha256_hash BY 'hash'`
--   `IDENTIFIED WITH double_sha1_password BY 'qwerty'`
--   `IDENTIFIED WITH double_sha1_hash BY 'hash'`
-
-#### Anfitrión del usuario {#user-host}
-
-El host de usuario es un host desde el que se podría establecer una conexión con el servidor ClickHouse. El host se puede especificar en el `HOST` sección de consulta de las siguientes maneras:
-
--   `HOST IP 'ip_address_or_subnetwork'` — User can connect to ClickHouse server only from the specified IP address or a [subred](https://en.wikipedia.org/wiki/Subnetwork). Ejemplos: `HOST IP '192.168.0.0/16'`, `HOST IP '2001:DB8::/32'`. Para su uso en producción, sólo especifique `HOST IP` elementos (direcciones IP y sus máscaras), ya que usan `host` y `host_regexp` podría causar latencia adicional.
--   `HOST ANY` — User can connect from any location. This is default option.
--   `HOST LOCAL` — User can connect only locally.
--   `HOST NAME 'fqdn'` — User host can be specified as FQDN. For example, `HOST NAME 'mysite.com'`.
--   `HOST NAME REGEXP 'regexp'` — You can use [pcre](http://www.pcre.org/) expresiones regulares al especificar hosts de usuario. Por ejemplo, `HOST NAME REGEXP '.*\.mysite\.com'`.
--   `HOST LIKE 'template'` — Allows you use the [LIKE](../functions/string-search-functions.md#function-like) operador para filtrar los hosts de usuario. Por ejemplo, `HOST LIKE '%'` es equivalente a `HOST ANY`, `HOST LIKE '%.mysite.com'` filtros todos los anfitriones en el `mysite.com` dominio.
-
-Otra forma de especificar el host es usar `@` sintaxis con el nombre de usuario. Ejemplos:
-
--   `CREATE USER mira@'127.0.0.1'` — Equivalent to the `HOST IP` sintaxis.
--   `CREATE USER mira@'localhost'` — Equivalent to the `HOST LOCAL` sintaxis.
--   `CREATE USER mira@'192.168.%.%'` — Equivalent to the `HOST LIKE` sintaxis.
-
-!!! info "Advertencia"
-    ClickHouse trata `user_name@'address'` como un nombre de usuario en su conjunto. Por lo tanto, técnicamente puede crear múltiples usuarios con `user_name` y diferentes construcciones después `@`. No recomendamos hacerlo.
-
-### Ejemplos {#create-user-examples}
-
-Crear la cuenta de usuario `mira` protegido por la contraseña `qwerty`:
-
-``` sql
-CREATE USER mira HOST IP '127.0.0.1' IDENTIFIED WITH sha256_password BY 'qwerty'
-```
-
-`mira` debe iniciar la aplicación cliente en el host donde se ejecuta el servidor ClickHouse.
-
-Crear la cuenta de usuario `john`, asignarle roles y hacer que estos roles sean predeterminados:
-
-``` sql
-CREATE USER john DEFAULT ROLE role1, role2
-```
-
-Crear la cuenta de usuario `john` y hacer todos sus roles futuros por defecto:
-
-``` sql
-ALTER USER user DEFAULT ROLE ALL
-```
-
-Cuando se asignará algún rol a `john` en el futuro se convertirá en predeterminado automáticamente.
-
-Crear la cuenta de usuario `john` y hacer todos sus futuros roles por defecto excepto `role1` y `role2`:
-
-``` sql
-ALTER USER john DEFAULT ROLE ALL EXCEPT role1, role2
-```
-
-## CREATE ROLE {#create-role-statement}
-
-Crea un [rol](../../operations/access-rights.md#role-management).
-
-### Sintaxis {#create-role-syntax}
-
-``` sql
-CREATE ROLE [IF NOT EXISTS | OR REPLACE] name
-    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [READONLY|WRITABLE] | PROFILE 'profile_name'] [,...]
-```
-
-### Descripci {#create-role-description}
-
-El rol es un conjunto de [privilegio](grant.md#grant-privileges). Un usuario concedido con un rol obtiene todos los privilegios de este rol.
-
-A un usuario se le pueden asignar varios roles. Los usuarios pueden aplicar sus roles otorgados en combinaciones arbitrarias por el [SET ROLE](misc.md#set-role-statement) instrucción. El ámbito final de los privilegios es un conjunto combinado de todos los privilegios de todos los roles aplicados. Si un usuario tiene privilegios otorgados directamente a su cuenta de usuario, también se combinan con los privilegios otorgados por roles.
-
-El usuario puede tener roles predeterminados que se aplican al iniciar sesión del usuario. Para establecer roles predeterminados, utilice el [SET DEFAULT ROLE](misc.md#set-default-role-statement) declaración o el [ALTER USER](alter.md#alter-user-statement) instrucción.
-
-Para revocar un rol, utilice el [REVOKE](revoke.md) instrucción.
-
-Para eliminar el rol, utilice el [DROP ROLE](misc.md#drop-role-statement) instrucción. El rol eliminado se revoca automáticamente de todos los usuarios y roles a los que se concedió.
-
-### Ejemplos {#create-role-examples}
-
-``` sql
-CREATE ROLE accountant;
-GRANT SELECT ON db.* TO accountant;
-```
-
-Esta secuencia de consultas crea el rol `accountant` que tiene el privilegio de leer datos del `accounting` base.
-
-Conceder el rol al usuario `mira`:
-
-``` sql
-GRANT accountant TO mira;
-```
-
-Después de conceder el rol, el usuario puede usarlo y realizar las consultas permitidas. Por ejemplo:
-
-``` sql
-SET ROLE accountant;
-SELECT * FROM db.*;
-```
-
-## CREATE ROW POLICY {#create-row-policy-statement}
-
-Crea un [filtro para filas](../../operations/access-rights.md#row-policy-management) que un usuario puede leer de una tabla.
-
-### Sintaxis {#create-row-policy-syntax}
-
-``` sql
-CREATE [ROW] POLICY [IF NOT EXISTS | OR REPLACE] policy_name [ON CLUSTER cluster_name] ON [db.]table
-    [AS {PERMISSIVE | RESTRICTIVE}]
-    [FOR SELECT]
-    [USING condition]
-    [TO {role [,...] | ALL | ALL EXCEPT role [,...]}]
-```
-
-#### Sección AS {#create-row-policy-as}
-
-Con esta sección puede crear políticas permisivas o restrictivas.
-
-La política permisiva concede acceso a las filas. Las políticas permisivas que se aplican a la misma tabla se combinan usando el valor booleano `OR` operador. Las políticas son permisivas de forma predeterminada.
-
-La política restrictiva restringe el acceso a la fila. Las políticas restrictivas que se aplican a la misma tabla se combinan usando el valor booleano `AND` operador.
-
-Las políticas restrictivas se aplican a las filas que pasaron los filtros permisivos. Si establece directivas restrictivas pero no directivas permisivas, el usuario no puede obtener ninguna fila de la tabla.
-
-#### Sección A {#create-row-policy-to}
-
-En la sección `TO` puede dar una lista mixta de roles y usuarios, por ejemplo, `CREATE ROW POLICY ... TO accountant, john@localhost`.
-
-Palabra clave `ALL` significa todos los usuarios de ClickHouse, incluido el usuario actual. Palabras clave `ALL EXCEPT` permitir excluir a algunos usuarios de la lista de todos los usuarios, por ejemplo `CREATE ROW POLICY ... TO ALL EXCEPT accountant, john@localhost`
-
-### Ejemplos {#examples}
-
--   `CREATE ROW POLICY filter ON mydb.mytable FOR SELECT USING a<1000 TO accountant, john@localhost`
--   `CREATE ROW POLICY filter ON mydb.mytable FOR SELECT USING a<1000 TO ALL EXCEPT mira`
-
-## CREATE QUOTA {#create-quota-statement}
-
-Crea un [cuota](../../operations/access-rights.md#quotas-management) que se puede asignar a un usuario o a un rol.
-
-### Sintaxis {#create-quota-syntax}
-
-``` sql
-CREATE QUOTA [IF NOT EXISTS | OR REPLACE] name [ON CLUSTER cluster_name]
-    [KEYED BY {'none' | 'user name' | 'ip address' | 'client key' | 'client key or user name' | 'client key or ip address'}]
-    [FOR [RANDOMIZED] INTERVAL number {SECOND | MINUTE | HOUR | DAY | WEEK | MONTH | QUARTER | YEAR}
-        {MAX { {QUERIES | ERRORS | RESULT ROWS | RESULT BYTES | READ ROWS | READ BYTES | EXECUTION TIME} = number } [,...] |
-         NO LIMITS | TRACKING ONLY} [,...]]
-    [TO {role [,...] | ALL | ALL EXCEPT role [,...]}]
-```
-
-### Ejemplo {#create-quota-example}
-
-Limite el número máximo de consultas para el usuario actual con 123 consultas en una restricción de 15 meses:
-
-``` sql
-CREATE QUOTA qA FOR INTERVAL 15 MONTH MAX QUERIES 123 TO CURRENT_USER
-```
-
-## CREATE SETTINGS PROFILE {#create-settings-profile-statement}
-
-Crea un [perfil de configuración](../../operations/access-rights.md#settings-profiles-management) que se puede asignar a un usuario o a un rol.
-
-### Sintaxis {#create-settings-profile-syntax}
-
-``` sql
-CREATE SETTINGS PROFILE [IF NOT EXISTS | OR REPLACE] name [ON CLUSTER cluster_name]
-    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [READONLY|WRITABLE] | INHERIT 'profile_name'] [,...]
-```
-
-# Ejemplo {#create-settings-profile-syntax}
-
-Crear el `max_memory_usage_profile` perfil de configuración con valor y restricciones para el `max_memory_usage` configuración. Asignarlo a `robin`:
-
-``` sql
-CREATE SETTINGS PROFILE max_memory_usage_profile SETTINGS max_memory_usage = 100000001 MIN 90000000 MAX 110000000 TO robin
-```

-# GRANT {#grant}
-
--   Conceder [privilegio](#grant-privileges) a las cuentas o roles de usuario de ClickHouse.
--   Asigna roles a cuentas de usuario u otros roles.
-
-Para revocar privilegios, utilice el [REVOKE](revoke.md) instrucción. También puede enumerar los privilegios concedidos por el [SHOW GRANTS](show.md#show-grants-statement) instrucción.
-
-## Concesión de sintaxis de privilegios {#grant-privigele-syntax}
-
-``` sql
-GRANT [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} TO {user | role | CURRENT_USER} [,...] [WITH GRANT OPTION]
-```
-
--   `privilege` — Type of privilege.
--   `role` — ClickHouse user role.
--   `user` — ClickHouse user account.
-
-El `WITH GRANT OPTION` subvenciones de cláusula `user` o `role` con permiso para realizar el `GRANT` consulta. Los usuarios pueden otorgar privilegios del mismo alcance que tienen y menos.
-
-## Concesión de sintaxis de roles {#assign-role-syntax}
-
-``` sql
-GRANT [ON CLUSTER cluster_name] role [,...] TO {user | another_role | CURRENT_USER} [,...] [WITH ADMIN OPTION]
-```
-
--   `role` — ClickHouse user role.
--   `user` — ClickHouse user account.
-
-El `WITH ADMIN OPTION` conjuntos de cláusulas [ADMIN OPTION](#admin-option-privilege) privilegio para `user` o `role`.
-
-## Uso {#grant-usage}
-
-Utilizar `GRANT` su cuenta debe tener el `GRANT OPTION` privilegio. Puede otorgar privilegios solo dentro del ámbito de los privilegios de su cuenta.
-
-Por ejemplo, el administrador ha otorgado privilegios a `john` cuenta por la consulta:
-
-``` sql
-GRANT SELECT(x,y) ON db.table TO john WITH GRANT OPTION
-```
-
-Significa que `john` tiene el permiso para realizar:
-
--   `SELECT x,y FROM db.table`.
--   `SELECT x FROM db.table`.
--   `SELECT y FROM db.table`.
-
-`john` no puede realizar `SELECT z FROM db.table`. El `SELECT * FROM db.table` también no está disponible. Al procesar esta consulta, ClickHouse no devuelve ningún dato, incluso `x` y `y`. La única excepción es si una tabla `x` y `y` columnas, en este caso ClickHouse devuelve todos los datos.
-
-También `john` tiene el `GRANT OPTION` privilegios, por lo que puede otorgar a otros usuarios con privilegios del mismo o del menor alcance.
-
-Especificación de privilegios que puede utilizar asterisco (`*`) en lugar de una tabla o un nombre de base de datos. Por ejemplo, el `GRANT SELECT ON db.* TO john` consulta permite `john` para realizar el `SELECT` consulta sobre todas las tablas en `db` base. Además, puede omitir el nombre de la base de datos. En este caso, se otorgan privilegios para la base de datos actual, por ejemplo: `GRANT SELECT ON * TO john` otorga el privilegio en todas las tablas de la base de datos actual, `GRANT SELECT ON mytable TO john` otorga el privilegio sobre el `mytable` tabla en la base de datos actual.
-
-Acceso a la `system` base de datos siempre está permitida (ya que esta base de datos se utiliza para procesar consultas).
-
-Puede conceder varios privilegios a varias cuentas en una consulta. Consulta `GRANT SELECT, INSERT ON *.* TO john, robin` permite cuentas `john` y `robin` para realizar el `INSERT` y `SELECT` consultas sobre todas las tablas en todas las bases de datos en el servidor.
-
-## Privilegio {#grant-privileges}
-
-Privilegio es un permiso para realizar un tipo específico de consultas.
-
-Los privilegios tienen una estructura jerárquica. Un conjunto de consultas permitidas depende del ámbito de privilegios.
-
-Jerarquía de privilegios:
-
--   [SELECT](#grant-select)
--   [INSERT](#grant-insert)
--   [ALTER](#grant-alter)
-    -   `ALTER TABLE`
-        -   `ALTER UPDATE`

--   [dictGet](#grant-dictget)
-
-Ejemplos de cómo se trata esta jerarquía:
-
--   El `ALTER` privilegio incluye todos los demás `ALTER*` privilegio.
--   `ALTER CONSTRAINT` incluir `ALTER ADD CONSTRAINT` y `ALTER DROP CONSTRAINT` privilegio.
-
-Los privilegios se aplican a diferentes niveles. Conocer un nivel sugiere sintaxis disponible para privilegios.
-
-Niveles (de menor a mayor):
-
--   `COLUMN` — Privilege can be granted for column, table, database, or globally.
--   `TABLE` — Privilege can be granted for table, database, or globally.
--   `VIEW` — Privilege can be granted for view, database, or globally.
--   `DICTIONARY` — Privilege can be granted for dictionary, database, or globally.
--   `DATABASE` — Privilege can be granted for database or globally.
--   `GLOBAL` — Privilege can be granted only globally.
--   `GROUP` — Groups privileges of different levels. When `GROUP`-level privilegio se concede, sólo los privilegios del grupo se conceden que corresponden a la sintaxis utilizada.
-
-Ejemplos de sintaxis permitida:
-
--   `GRANT SELECT(x) ON db.table TO user`
--   `GRANT SELECT ON db.* TO user`
-
-Ejemplos de sintaxis no permitida:
-
--   `GRANT CREATE USER(x) ON db.table TO user`
--   `GRANT CREATE USER ON db.* TO user`
-
-El privilegio especial [ALL](#grant-all) otorga todos los privilegios a una cuenta de usuario o un rol.
-
-De forma predeterminada, una cuenta de usuario o un rol no tiene privilegios.
-
-Si un usuario o rol no tiene privilegios, se muestra como [NONE](#grant-none) privilegio.
-
-Algunas consultas por su implementación requieren un conjunto de privilegios. Por ejemplo, para realizar el [RENAME](misc.md#misc_operations-rename) consulta necesita los siguientes privilegios: `SELECT`, `CREATE TABLE`, `INSERT` y `DROP TABLE`.
-
-### SELECT {#grant-select}
-
-Permite realizar [SELECT](select/index.md) consulta.
-
-Nivel de privilegio: `COLUMN`.
-
-**Descripci**
-
-El usuario concedido con este privilegio puede realizar `SELECT` consultas sobre una lista especificada de columnas en la tabla y la base de datos especificadas. Si el usuario incluye otras columnas, entonces se especifica una consulta no devuelve datos.
-
-Considere el siguiente privilegio:
-
-``` sql
-GRANT SELECT(x,y) ON db.table TO john
-```
-
-Este privilegio permite `john` realizar cualquier `SELECT` consulta que involucra datos de la `x` y/o `y` columnas en `db.table`. Por ejemplo, `SELECT x FROM db.table`. `john` no puede realizar `SELECT z FROM db.table`. El `SELECT * FROM db.table` también no está disponible. Al procesar esta consulta, ClickHouse no devuelve ningún dato, incluso `x` y `y`. La única excepción es si una tabla `x` y `y` columnas, en este caso ClickHouse devuelve todos los datos.
-
-### INSERT {#grant-insert}
-
-Permite realizar [INSERT](insert-into.md) consulta.
-
-Nivel de privilegio: `COLUMN`.
-
-**Descripci**
-
-El usuario concedido con este privilegio puede realizar `INSERT` consultas sobre una lista especificada de columnas en la tabla y la base de datos especificadas. Si el usuario incluye otras columnas, entonces se especifica una consulta no inserta ningún dato.
-
-**Ejemplo**
-
-``` sql
-GRANT INSERT(x,y) ON db.table TO john
-```
-
-El privilegio concedido permite `john` para insertar datos en el `x` y/o `y` columnas en `db.table`.
-
-### ALTER {#grant-alter}
-
-Permite realizar [ALTER](alter.md) consultas correspondientes a la siguiente jerarquía de privilegios:
-
--   `ALTER`. Nivel: `COLUMN`.

-
-## INSERT {#insert}
-
-Adición de datos.
-
-Formato de consulta básico:
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] VALUES (v11, v12, v13), (v21, v22, v23), ...
-```
-
-La consulta puede especificar una lista de columnas para insertar `[(c1, c2, c3)]`. En este caso, el resto de las columnas se llenan con:
-
--   Los valores calculados a partir del `DEFAULT` expresiones especificadas en la definición de la tabla.
--   Ceros y cadenas vacías, si `DEFAULT` expresiones no están definidas.
-
-Si [strict_insert_defaults=1](../../operations/settings/settings.md), columnas que no tienen `DEFAULT` definido debe figurar en la consulta.
-
-Los datos se pueden pasar al INSERT en cualquier [formato](../../interfaces/formats.md#formats) con el apoyo de ClickHouse. El formato debe especificarse explícitamente en la consulta:
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] FORMAT format_name data_set
-```
-
-For example, the following query format is identical to the basic version of INSERT … VALUES:
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] FORMAT Values (v11, v12, v13), (v21, v22, v23), ...
-```
-
-ClickHouse elimina todos los espacios y un avance de línea (si hay uno) antes de los datos. Al formar una consulta, recomendamos colocar los datos en una nueva línea después de los operadores de consulta (esto es importante si los datos comienzan con espacios).
-
-Ejemplo:
-
-``` sql
-INSERT INTO t FORMAT TabSeparated
-11  Hello, world!
-22  Qwerty
-```
-
-Puede insertar datos por separado de la consulta mediante el cliente de línea de comandos o la interfaz HTTP. Para obtener más información, consulte la sección “[Interfaz](../../interfaces/index.md#interfaces)”.
-
-### Limitación {#constraints}
-
-Si la tabla tiene [limitación](create.md#constraints), their expressions will be checked for each row of inserted data. If any of those constraints is not satisfied — server will raise an exception containing constraint name and expression, the query will be stopped.
-
-### Insertar los resultados de `SELECT` {#insert_query_insert-select}
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] SELECT ...
-```
-
-Las columnas se asignan de acuerdo con su posición en la cláusula SELECT. Sin embargo, sus nombres en la expresión SELECT y la tabla para INSERT pueden diferir. Si es necesario, se realiza la fundición de tipo.
-
-Ninguno de los formatos de datos, excepto Valores, permite establecer valores para expresiones como `now()`, `1 + 2` y así sucesivamente. El formato Values permite el uso limitado de expresiones, pero esto no se recomienda, porque en este caso se usa código ineficiente para su ejecución.
-
-No se admiten otras consultas para modificar partes de datos: `UPDATE`, `DELETE`, `REPLACE`, `MERGE`, `UPSERT`, `INSERT UPDATE`.
-Sin embargo, puede eliminar datos antiguos usando `ALTER TABLE ... DROP PARTITION`.
-
-`FORMAT` cláusula debe especificarse al final de la consulta si `SELECT` cláusula contiene la función de tabla [entrada()](../table-functions/input.md).
-
-### Consideraciones de rendimiento {#performance-considerations}
-
-`INSERT` ordena los datos de entrada por clave principal y los divide en particiones por una clave de partición. Si inserta datos en varias particiones a la vez, puede reducir significativamente el rendimiento del `INSERT` consulta. Para evitar esto:
-
--   Agregue datos en lotes bastante grandes, como 100.000 filas a la vez.
--   Agrupe los datos por una clave de partición antes de cargarlos en ClickHouse.
-
-El rendimiento no disminuirá si:
-
--   Los datos se agregan en tiempo real.
--   Carga datos que normalmente están ordenados por tiempo.

-# Consultas Misceláneas {#miscellaneous-queries}
-
-## ATTACH {#attach}
-
-Esta consulta es exactamente la misma que `CREATE`, pero
-
--   En lugar de la palabra `CREATE` utiliza la palabra `ATTACH`.
--   La consulta no crea datos en el disco, pero supone que los datos ya están en los lugares apropiados, y simplemente agrega información sobre la tabla al servidor.
-    Después de ejecutar una consulta ATTACH, el servidor sabrá sobre la existencia de la tabla.
-
-Si la tabla se separó previamente (`DETACH`), lo que significa que su estructura es conocida, puede usar taquigrafía sin definir la estructura.
-
-``` sql
-ATTACH TABLE [IF NOT EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Esta consulta se utiliza al iniciar el servidor. El servidor almacena los metadatos de la tabla como archivos con `ATTACH` consultas, que simplemente se ejecuta en el lanzamiento (con la excepción de las tablas del sistema, que se crean explícitamente en el servidor).
-
-## CHECK TABLE {#check-table}
-
-Comprueba si los datos de la tabla están dañados.
-
-``` sql
-CHECK TABLE [db.]name
-```
-
-El `CHECK TABLE` query compara los tamaños de archivo reales con los valores esperados que se almacenan en el servidor. Si los tamaños de archivo no coinciden con los valores almacenados, significa que los datos están dañados. Esto puede deberse, por ejemplo, a un bloqueo del sistema durante la ejecución de la consulta.
-
-La respuesta de consulta contiene el `result` columna con una sola fila. La fila tiene un valor de
-[Booleana](../../sql-reference/data-types/boolean.md) tipo:
-
--   0 - Los datos de la tabla están dañados.
--   1 - Los datos mantienen la integridad.
-
-El `CHECK TABLE` query admite los siguientes motores de tablas:
-
--   [Registro](../../engines/table-engines/log-family/log.md)
--   [TinyLog](../../engines/table-engines/log-family/tinylog.md)
--   [StripeLog](../../engines/table-engines/log-family/stripelog.md)
--   [Familia MergeTree](../../engines/table-engines/mergetree-family/mergetree.md)
-
-Realizado sobre las tablas con otros motores de tabla causa una excepción.
-
-Motores del `*Log` la familia no proporciona la recuperación automática de datos en caso de fallo. Utilice el `CHECK TABLE` consulta para rastrear la pérdida de datos de manera oportuna.
-
-Para `MergeTree` motores familiares, el `CHECK TABLE` query muestra un estado de comprobación para cada parte de datos individual de una tabla en el servidor local.
-
-**Si los datos están dañados**
-
-Si la tabla está dañada, puede copiar los datos no dañados a otra tabla. Para hacer esto:
-
-1.  Cree una nueva tabla con la misma estructura que la tabla dañada. Para ello, ejecute la consulta `CREATE TABLE <new_table_name> AS <damaged_table_name>`.
-2.  Establezca el [max_threads](../../operations/settings/settings.md#settings-max_threads) valor a 1 para procesar la siguiente consulta en un único subproceso. Para ello, ejecute la consulta `SET max_threads = 1`.
-3.  Ejecutar la consulta `INSERT INTO <new_table_name> SELECT * FROM <damaged_table_name>`. Esta solicitud copia los datos no dañados de la tabla dañada a otra tabla. Solo se copiarán los datos anteriores a la parte dañada.
-4.  Reinicie el `clickhouse-client` para restablecer el `max_threads` valor.
-
-## DESCRIBE TABLE {#misc-describe-table}
-
-``` sql
-DESC|DESCRIBE TABLE [db.]table [INTO OUTFILE filename] [FORMAT format]
-```
-
-Devuelve lo siguiente `String` tipo columnas:
-
--   `name` — Column name.
--   `type`— Column type.
--   `default_type` — Clause that is used in [expresión predeterminada](create.md#create-default-values) (`DEFAULT`, `MATERIALIZED` o `ALIAS`). La columna contiene una cadena vacía, si no se especifica la expresión predeterminada.
--   `default_expression` — Value specified in the `DEFAULT` clausula.
--   `comment_expression` — Comment text.
-
-Las estructuras de datos anidadas se generan en “expanded” formato. Cada columna se muestra por separado, con el nombre después de un punto.
-
-## DETACH {#detach}
-
-Elimina información sobre el ‘name’ tabla desde el servidor. El servidor deja de saber sobre la existencia de la tabla.
-
-``` sql
-DETACH TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Esto no elimina los datos ni los metadatos de la tabla. En el próximo lanzamiento del servidor, el servidor leerá los metadatos y volverá a conocer la tabla.
-Del mismo modo, un “detached” se puede volver a conectar usando el `ATTACH` consulta (con la excepción de las tablas del sistema, que no tienen metadatos almacenados para ellas).
-
-No hay `DETACH DATABASE` consulta.
-
-## DROP {#drop}
-
-Esta consulta tiene dos tipos: `DROP DATABASE` y `DROP TABLE`.
-
-``` sql
-DROP DATABASE [IF EXISTS] db [ON CLUSTER cluster]
-```
-
-Elimina todas las tablas dentro del ‘db’ base de datos, a continuación, elimina ‘db’ base de datos en sí.
-Si `IF EXISTS` se especifica, no devuelve un error si la base de datos no existe.
-
-``` sql
-DROP [TEMPORARY] TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Elimina la tabla.
-Si `IF EXISTS` se especifica, no devuelve un error si la tabla no existe o la base de datos no existe.
-
-    DROP DICTIONARY [IF EXISTS] [db.]name
-
-Elimina el diccionario.
-Si `IF EXISTS` se especifica, no devuelve un error si la tabla no existe o la base de datos no existe.
-
-## DROP USER {#drop-user-statement}
-
-Elimina un usuario.
-
-### Sintaxis {#drop-user-syntax}
-
-``` sql
-DROP USER [IF EXISTS] name [,...] [ON CLUSTER cluster_name]
-```

-
-El rol eliminado se revoca de todas las entidades donde se concedió.
-
-### Sintaxis {#drop-role-syntax}
-
-``` sql

-```
-
-## DROP ROW POLICY {#drop-row-policy-statement}
-
-Elimina una directiva de fila.
-
-La directiva de filas eliminadas se revoca de todas las entidades a las que se asignó.
-
-### Sintaxis {#drop-row-policy-syntax}
-
-``` sql
-DROP [ROW] POLICY [IF EXISTS] name [,...] ON [database.]table [,...] [ON CLUSTER cluster_name]
-```
-
-## DROP QUOTA {#drop-quota-statement}
-
-Elimina una cuota.
-
-La cuota eliminada se revoca de todas las entidades a las que se asignó.
-
-### Sintaxis {#drop-quota-syntax}

-```
-
-## DROP SETTINGS PROFILE {#drop-settings-profile-statement}
-
-Elimina una cuota.
-
-La cuota eliminada se revoca de todas las entidades a las que se asignó.
-
-### Sintaxis {#drop-settings-profile-syntax}
-
-``` sql
-DROP [SETTINGS] PROFILE [IF EXISTS] name [,...] [ON CLUSTER cluster_name]
-```
-
-## EXISTS {#exists-statement}
-
-``` sql

-Devuelve una sola `UInt8`columna -type, que contiene el valor único `0` si la tabla o base de datos no existe, o `1` si la tabla existe en la base de datos especificada.
-
-## KILL QUERY {#kill-query-statement}
-
-``` sql
-KILL QUERY [ON CLUSTER cluster]
-  WHERE <where expression to SELECT FROM system.processes query>
-  [SYNC|ASYNC|TEST]
-  [FORMAT format]
-```
-
-Intenta terminar por la fuerza las consultas que se están ejecutando actualmente.
-Las consultas a finalizar se seleccionan en el sistema.tabla de procesos utilizando los criterios definidos en el `WHERE` cláusula de la `KILL` consulta.
-
-Ejemplos:
-
-``` sql
--- Forcibly terminates all queries with the specified query_id:
-KILL QUERY WHERE query_id='2-857d-4a57-9ee0-327da5d60a90'
-
--- Synchronously terminates all queries run by 'username':
-KILL QUERY WHERE user='username' SYNC
-```
-
-Los usuarios de solo lectura solo pueden detener sus propias consultas.
-
-De forma predeterminada, se utiliza la versión asincrónica de las consultas (`ASYNC`), que no espera la confirmación de que las consultas se han detenido.
-
-La versión síncrona (`SYNC`) espera a que se detengan todas las consultas y muestra información sobre cada proceso a medida que se detiene.
-La respuesta contiene el `kill_status` columna, que puede tomar los siguientes valores:
-
-1.  ‘finished’ – The query was terminated successfully.
-2.  ‘waiting’ – Waiting for the query to end after sending it a signal to terminate.
-3.  The other values ​​explain why the query can't be stopped.
-
-Una consulta de prueba (`TEST`) sólo comprueba los derechos del usuario y muestra una lista de consultas para detener.
-
-## KILL MUTATION {#kill-mutation}
-
-``` sql
-KILL MUTATION [ON CLUSTER cluster]
-  WHERE <where expression to SELECT FROM system.mutations query>
-  [TEST]
-  [FORMAT format]
-```
-
-Intenta cancelar y quitar [mutación](alter.md#alter-mutations) que se están ejecutando actualmente. Las mutaciones para cancelar se seleccionan en el [`system.mutations`](../../operations/system-tables.md#system_tables-mutations) utilizando el filtro especificado por el `WHERE` cláusula de la `KILL` consulta.
-
-Una consulta de prueba (`TEST`) sólo comprueba los derechos del usuario y muestra una lista de consultas para detener.
-
-Ejemplos:
-
-``` sql
--- Cancel and remove all mutations of the single table:
-KILL MUTATION WHERE database = 'default' AND table = 'table'
-
--- Cancel the specific mutation:
-KILL MUTATION WHERE database = 'default' AND table = 'table' AND mutation_id = 'mutation_3.txt'
-```
-
-The query is useful when a mutation is stuck and cannot finish (e.g. if some function in the mutation query throws an exception when applied to the data contained in the table).
-
-Los cambios ya realizados por la mutación no se revierten.
-
-## OPTIMIZE {#misc_operations-optimize}
-
-``` sql
-OPTIMIZE TABLE [db.]name [ON CLUSTER cluster] [PARTITION partition | PARTITION ID 'partition_id'] [FINAL] [DEDUPLICATE]
-```
-
-Esta consulta intenta inicializar una combinación no programada de partes de datos para tablas con un motor de tablas [Método de codificación de datos:](../../engines/table-engines/mergetree-family/mergetree.md) familia.
-
-El `OPTMIZE` consulta también es compatible con el [Método de codificación de datos:](../../engines/table-engines/special/materializedview.md) y el [Búfer](../../engines/table-engines/special/buffer.md) motor. No se admiten otros motores de tabla.
-
-Cuando `OPTIMIZE` se utiliza con el [ReplicatedMergeTree](../../engines/table-engines/mergetree-family/replication.md) la familia de motores de tablas, ClickHouse crea una tarea para fusionar y espera la ejecución en todos los nodos (si `replication_alter_partitions_sync` está habilitada la configuración).
-
--   Si `OPTIMIZE` no realiza una fusión por ningún motivo, no notifica al cliente. Para habilitar las notificaciones, [Optize_throw_if_noop](../../operations/settings/settings.md#setting-optimize_throw_if_noop) configuración.
--   Si especifica un `PARTITION`, sólo la partición especificada está optimizada. [Cómo establecer la expresión de partición](alter.md#alter-how-to-specify-part-expr).
--   Si especifica `FINAL`, la optimización se realiza incluso cuando todos los datos ya están en una parte.
--   Si especifica `DEDUPLICATE`, luego se deduplicarán filas completamente idénticas (se comparan todas las columnas), tiene sentido solo para el motor MergeTree.
-
-!!! warning "Advertencia"
-    `OPTIMIZE` no se puede arreglar el “Too many parts” error.
-
-## RENAME {#misc_operations-rename}
-
-Cambia el nombre de una o más tablas.
-
-``` sql
-RENAME TABLE [db11.]name11 TO [db12.]name12, [db21.]name21 TO [db22.]name22, ... [ON CLUSTER cluster]
-```
-
-Todas las tablas se renombran bajo bloqueo global. Cambiar el nombre de las tablas es una operación ligera. Si ha indicado otra base de datos después de TO, la tabla se moverá a esta base de datos. Sin embargo, los directorios con bases de datos deben residir en el mismo sistema de archivos (de lo contrario, se devuelve un error).
-
-## SET {#query-set}
-
-``` sql
-SET param = value
-```
-
-Asignar `value` a la `param` [configuración](../../operations/settings/index.md) para la sesión actual. No se puede cambiar [configuración del servidor](../../operations/server-configuration-parameters/index.md) de esta manera.
-
-También puede establecer todos los valores del perfil de configuración especificado en una sola consulta.
-
-``` sql
-SET profile = 'profile-name-from-the-settings-file'
-```
-
-Para obtener más información, consulte [Configuración](../../operations/settings/settings.md).
-
-## SET ROLE {#set-role-statement}
-
-Activa roles para el usuario actual.
-
-### Sintaxis {#set-role-syntax}
-
-``` sql
-SET ROLE {DEFAULT | NONE | role [,...] | ALL | ALL EXCEPT role [,...]}
-```
-
-## SET DEFAULT ROLE {#set-default-role-statement}
-
-Establece roles predeterminados para un usuario.
-
-Los roles predeterminados se activan automáticamente al iniciar sesión del usuario. Puede establecer como predeterminado sólo los roles concedidos anteriormente. Si el rol no se concede a un usuario, ClickHouse produce una excepción.
-
-### Sintaxis {#set-default-role-syntax}
-
-``` sql
-SET DEFAULT ROLE {NONE | role [,...] | ALL | ALL EXCEPT role [,...]} TO {user|CURRENT_USER} [,...]
-```
-
-### Ejemplos {#set-default-role-examples}
-
-Establecer varios roles predeterminados para un usuario:
-
-``` sql
-SET DEFAULT ROLE role1, role2, ... TO user
-```
-
-Establezca todos los roles concedidos como predeterminados para un usuario:
-
-``` sql
-SET DEFAULT ROLE ALL TO user
-```
-
-Borrar roles predeterminados de un usuario:
-
-``` sql
-SET DEFAULT ROLE NONE TO user
-```
-
-Establezca todos los roles concedidos como predeterminados excepto algunos de ellos:
-
-``` sql
-SET DEFAULT ROLE ALL EXCEPT role1, role2 TO user
-```
-
-## TRUNCATE {#truncate-statement}
-
-``` sql
-TRUNCATE TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Elimina todos los datos de una tabla. Cuando la cláusula `IF EXISTS` se omite, la consulta devuelve un error si la tabla no existe.
-
-El `TRUNCATE` consulta no es compatible con [Vista](../../engines/table-engines/special/view.md), [File](../../engines/table-engines/special/file.md), [URL](../../engines/table-engines/special/url.md) y [Nulo](../../engines/table-engines/special/null.md) motores de mesa.
-
-## USE {#use}
-
-``` sql
-USE db
-```
-
-Permite establecer la base de datos actual para la sesión.
-La base de datos actual se utiliza para buscar tablas si la base de datos no está definida explícitamente en la consulta con un punto antes del nombre de la tabla.
-Esta consulta no se puede realizar cuando se usa el protocolo HTTP, ya que no existe un concepto de sesión.

-# REVOKE {#revoke}
-
-Revoca privilegios de usuarios o roles.
-
-## Sintaxis {#revoke-syntax}
-
-**Revocación de privilegios de usuarios**
-
-``` sql
-REVOKE [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} FROM {user | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user | CURRENT_USER} [,...]
-```
-
-**Revocación de roles de usuarios**
-
-``` sql
-REVOKE [ON CLUSTER cluster_name] [ADMIN OPTION FOR] role [,...] FROM {user | role | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user_name | role_name | CURRENT_USER} [,...]
-```
-
-## Descripci {#revoke-description}
-
-Para revocar algún privilegio, puede usar un privilegio de alcance más amplio que planea revocar. Por ejemplo, si un usuario tiene `SELECT (x,y)` privilegio, administrador puede realizar `REVOKE SELECT(x,y) ...`, o `REVOKE SELECT * ...` o incluso `REVOKE ALL PRIVILEGES ...` consulta para revocar este privilegio.
-
-### Revocaciones parciales {#partial-revokes-dscr}
-
-Puede revocar una parte de un privilegio. Por ejemplo, si un usuario tiene `SELECT *.*` privilegio puede revocarle un privilegio para leer datos de alguna tabla o una base de datos.
-
-## Ejemplos {#revoke-example}
-
-Otorgue el `john` cuenta de usuario con un privilegio para seleccionar de todas las bases de datos `accounts` una:
-
-``` sql
-GRANT SELECT ON *.* TO john;
-REVOKE SELECT ON accounts.* FROM john;
-```
-
-Otorgue el `mira` cuenta de usuario con un privilegio para seleccionar entre todas las columnas `accounts.staff` excepción de la tabla `wage` una.
-
-``` sql
-GRANT SELECT ON accounts.staff TO mira;
-REVOKE SELECT(wage) ON accounts.staff FROM mira;
-```

-# ARRAY JOIN Cláusula {#select-array-join-clause}
-
-Es una operación común para las tablas que contienen una columna de matriz para producir una nueva tabla que tiene una columna con cada elemento de matriz individual de esa columna inicial, mientras que los valores de otras columnas se duplican. Este es el caso básico de lo que `ARRAY JOIN` cláusula hace.
-
-Su nombre proviene del hecho de que se puede considerar como una ejecución `JOIN` con una matriz o estructura de datos anidada. La intención es similar a la [arrayJoin](../../functions/array-join.md#functions_arrayjoin) función, pero la funcionalidad de la cláusula es más amplia.
-
-Sintaxis:
-
-``` sql
-SELECT <expr_list>
-FROM <left_subquery>
-[LEFT] ARRAY JOIN <array>
-[WHERE|PREWHERE <expr>]
-...
-```
-
-Solo puede especificar uno `ARRAY JOIN` cláusula en una `SELECT` consulta.
-
-Tipos admitidos de `ARRAY JOIN` se enumeran a continuación:
-
--   `ARRAY JOIN` - En el caso base, las matrices vacías no se incluyen en el resultado de `JOIN`.
--   `LEFT ARRAY JOIN` - El resultado de `JOIN` contiene filas con matrices vacías. El valor de una matriz vacía se establece en el valor predeterminado para el tipo de elemento de matriz (normalmente 0, cadena vacía o NULL).
-
-## Ejemplos básicos de ARRAY JOIN {#basic-array-join-examples}
-
-Los siguientes ejemplos demuestran el uso de la `ARRAY JOIN` y `LEFT ARRAY JOIN` clausula. Vamos a crear una tabla con un [Matriz](../../../sql-reference/data-types/array.md) escriba la columna e inserte valores en ella:
-
-``` sql
-CREATE TABLE arrays_test
-(
-    s String,
-    arr Array(UInt8)
-) ENGINE = Memory;
-
-INSERT INTO arrays_test
-VALUES ('Hello', [1,2]), ('World', [3,4,5]), ('Goodbye', []);
-```
-
-``` text
-┌─s───────────┬─arr─────┐
-│ Hello       │ [1,2]   │
-│ World       │ [3,4,5] │
-│ Goodbye     │ []      │
-└─────────────┴─────────┘
-```
-
-El siguiente ejemplo utiliza el `ARRAY JOIN` clausula:
-
-``` sql
-SELECT s, arr
-FROM arrays_test
-ARRAY JOIN arr;
-```
-
-``` text
-┌─s─────┬─arr─┐
-│ Hello │   1 │
-│ Hello │   2 │
-│ World │   3 │
-│ World │   4 │
-│ World │   5 │
-└───────┴─────┘
-```
-
-El siguiente ejemplo utiliza el `LEFT ARRAY JOIN` clausula:
-
-``` sql
-SELECT s, arr
-FROM arrays_test
-LEFT ARRAY JOIN arr;
-```
-
-``` text
-┌─s───────────┬─arr─┐
-│ Hello       │   1 │
-│ Hello       │   2 │
-│ World       │   3 │
-│ World       │   4 │
-│ World       │   5 │
-│ Goodbye     │   0 │
-└─────────────┴─────┘
-```
-
-## Uso de alias {#using-aliases}
-
-Se puede especificar un alias para una matriz en el `ARRAY JOIN` clausula. En este caso, este alias puede acceder a un elemento de matriz, pero el nombre original tiene acceso a la matriz en sí. Ejemplo:
-
-``` sql
-SELECT s, arr, a
-FROM arrays_test
-ARRAY JOIN arr AS a;
-```
-
-``` text
-┌─s─────┬─arr─────┬─a─┐
-│ Hello │ [1,2]   │ 1 │
-│ Hello │ [1,2]   │ 2 │
-│ World │ [3,4,5] │ 3 │
-│ World │ [3,4,5] │ 4 │
-│ World │ [3,4,5] │ 5 │
-└───────┴─────────┴───┘
-```
-
-Usando alias, puede realizar `ARRAY JOIN` con una matriz externa. Por ejemplo:
-
-``` sql
-SELECT s, arr_external
-FROM arrays_test
-ARRAY JOIN [1, 2, 3] AS arr_external;
-```
-
-``` text
-┌─s───────────┬─arr_external─┐
-│ Hello       │            1 │
-│ Hello       │            2 │
-│ Hello       │            3 │
-│ World       │            1 │
-│ World       │            2 │
-│ World       │            3 │
-│ Goodbye     │            1 │
-│ Goodbye     │            2 │
-│ Goodbye     │            3 │
-└─────────────┴──────────────┘
-```
-
-Múltiples matrices se pueden separar por comas en el `ARRAY JOIN` clausula. En este caso, `JOIN` se realiza con ellos simultáneamente (la suma directa, no el producto cartesiano). Tenga en cuenta que todas las matrices deben tener el mismo tamaño. Ejemplo:
-
-``` sql
-SELECT s, arr, a, num, mapped
-FROM arrays_test
-ARRAY JOIN arr AS a, arrayEnumerate(arr) AS num, arrayMap(x -> x + 1, arr) AS mapped;
-```
-
-``` text
-┌─s─────┬─arr─────┬─a─┬─num─┬─mapped─┐
-│ Hello │ [1,2]   │ 1 │   1 │      2 │
-│ Hello │ [1,2]   │ 2 │   2 │      3 │
-│ World │ [3,4,5] │ 3 │   1 │      4 │
-│ World │ [3,4,5] │ 4 │   2 │      5 │
-│ World │ [3,4,5] │ 5 │   3 │      6 │
-└───────┴─────────┴───┴─────┴────────┘
-```
-
-El siguiente ejemplo utiliza el [arrayEnumerate](../../../sql-reference/functions/array-functions.md#array_functions-arrayenumerate) función:
-
-``` sql
-SELECT s, arr, a, num, arrayEnumerate(arr)
-FROM arrays_test
-ARRAY JOIN arr AS a, arrayEnumerate(arr) AS num;
-```
-
-``` text
-┌─s─────┬─arr─────┬─a─┬─num─┬─arrayEnumerate(arr)─┐
-│ Hello │ [1,2]   │ 1 │   1 │ [1,2]               │
-│ Hello │ [1,2]   │ 2 │   2 │ [1,2]               │
-│ World │ [3,4,5] │ 3 │   1 │ [1,2,3]             │
-│ World │ [3,4,5] │ 4 │   2 │ [1,2,3]             │
-│ World │ [3,4,5] │ 5 │   3 │ [1,2,3]             │
-└───────┴─────────┴───┴─────┴─────────────────────┘
-```
-
-## ARRAY JOIN con estructura de datos anidada {#array-join-with-nested-data-structure}
-
-`ARRAY JOIN` también funciona con [estructuras de datos anidados](../../../sql-reference/data-types/nested-data-structures/nested.md):
-
-``` sql
-CREATE TABLE nested_test
-(
-    s String,
-    nest Nested(
-    x UInt8,
-    y UInt32)
-) ENGINE = Memory;
-
-INSERT INTO nested_test
-VALUES ('Hello', [1,2], [10,20]), ('World', [3,4,5], [30,40,50]), ('Goodbye', [], []);
-```
-
-``` text
-┌─s───────┬─nest.x──┬─nest.y─────┐
-│ Hello   │ [1,2]   │ [10,20]    │
-│ World   │ [3,4,5] │ [30,40,50] │
-│ Goodbye │ []      │ []         │
-└─────────┴─────────┴────────────┘
-```
-
-``` sql
-SELECT s, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN nest;
-```
-
-``` text
-┌─s─────┬─nest.x─┬─nest.y─┐
-│ Hello │      1 │     10 │
-│ Hello │      2 │     20 │
-│ World │      3 │     30 │
-│ World │      4 │     40 │
-│ World │      5 │     50 │
-└───────┴────────┴────────┘
-```
-
-Al especificar nombres de estructuras de datos anidadas en `ARRAY JOIN` el significado es el mismo `ARRAY JOIN` con todos los elementos de la matriz en los que consiste. Los ejemplos se enumeran a continuación:
-
-``` sql
-SELECT s, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN `nest.x`, `nest.y`;
-```
-
-``` text
-┌─s─────┬─nest.x─┬─nest.y─┐
-│ Hello │      1 │     10 │
-│ Hello │      2 │     20 │
-│ World │      3 │     30 │
-│ World │      4 │     40 │
-│ World │      5 │     50 │
-└───────┴────────┴────────┘
-```
-
-Esta variación también tiene sentido:
-
-``` sql
-SELECT s, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN `nest.x`;
-```
-
-``` text
-┌─s─────┬─nest.x─┬─nest.y─────┐
-│ Hello │      1 │ [10,20]    │
-│ Hello │      2 │ [10,20]    │
-│ World │      3 │ [30,40,50] │
-│ World │      4 │ [30,40,50] │
-│ World │      5 │ [30,40,50] │
-└───────┴────────┴────────────┘
-```
-
-Se puede usar un alias para una estructura de datos anidada, con el fin de seleccionar `JOIN` resultado o la matriz de origen. Ejemplo:
-
-``` sql
-SELECT s, `n.x`, `n.y`, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN nest AS n;
-```
-
-``` text
-┌─s─────┬─n.x─┬─n.y─┬─nest.x──┬─nest.y─────┐
-│ Hello │   1 │  10 │ [1,2]   │ [10,20]    │
-│ Hello │   2 │  20 │ [1,2]   │ [10,20]    │
-│ World │   3 │  30 │ [3,4,5] │ [30,40,50] │
-│ World │   4 │  40 │ [3,4,5] │ [30,40,50] │
-│ World │   5 │  50 │ [3,4,5] │ [30,40,50] │
-└───────┴─────┴─────┴─────────┴────────────┘
-```
-
-Ejemplo de uso del [arrayEnumerate](../../../sql-reference/functions/array-functions.md#array_functions-arrayenumerate) función:
-
-``` sql
-SELECT s, `n.x`, `n.y`, `nest.x`, `nest.y`, num
-FROM nested_test
-ARRAY JOIN nest AS n, arrayEnumerate(`nest.x`) AS num;
-```
-
-``` text
-┌─s─────┬─n.x─┬─n.y─┬─nest.x──┬─nest.y─────┬─num─┐

-## Detalles de implementación {#implementation-details}
-
-El orden de ejecución de la consulta se optimiza cuando se ejecuta `ARRAY JOIN`. Aunque `ARRAY JOIN` debe especificarse siempre antes de la [WHERE](where.md)/[PREWHERE](prewhere.md) cláusula en una consulta, técnicamente se pueden realizar en cualquier orden, a menos que resultado de `ARRAY JOIN` se utiliza para filtrar. El optimizador de consultas controla el orden de procesamiento.

-# Cláusula DISTINCT {#select-distinct}
-
-Si `SELECT DISTINCT` se especifica, sólo las filas únicas permanecerán en un resultado de consulta. Por lo tanto, solo quedará una sola fila de todos los conjuntos de filas completamente coincidentes en el resultado.
-
-## Procesamiento nulo {#null-processing}
-
-`DISTINCT` trabaja con [NULL](../../syntax.md#null-literal) como si `NULL` Era un valor específico, y `NULL==NULL`. En otras palabras, en el `DISTINCT` resultados, diferentes combinaciones con `NULL` se producen sólo una vez. Se diferencia de `NULL` procesamiento en la mayoría de los otros contextos.
-
-## Alternativa {#alternatives}
-
-Es posible obtener el mismo resultado aplicando [GROUP BY](group-by.md) en el mismo conjunto de valores especificados como `SELECT` cláusula, sin utilizar ninguna función agregada. Pero hay pocas diferencias de `GROUP BY` enfoque:
-
--   `DISTINCT` se puede aplicar junto con `GROUP BY`.
--   Cuando [ORDER BY](order-by.md) se omite y [LIMIT](limit.md) se define, la consulta deja de ejecutarse inmediatamente después de que se haya leído el número requerido de filas diferentes.
--   Los bloques de datos se generan a medida que se procesan, sin esperar a que finalice la ejecución de toda la consulta.
-
-## Limitacion {#limitations}
-
-`DISTINCT` no se admite si `SELECT` tiene al menos una columna de matriz.
-
-## Ejemplos {#examples}
-
-ClickHouse admite el uso de `DISTINCT` y `ORDER BY` para diferentes columnas en una consulta. El `DISTINCT` cláusula se ejecuta antes de `ORDER BY` clausula.

-# FORMAT Cláusula {#format-clause}
-
-ClickHouse soporta una amplia gama de [formatos de serialización](../../../interfaces/formats.md) que se pueden usar en los resultados de consultas, entre otras cosas. Hay varias formas de elegir un formato para `SELECT` salida, uno de ellos es especificar `FORMAT format` al final de la consulta para obtener los datos resultantes en cualquier formato específico.
-
-El formato específico se puede utilizar ya sea por conveniencia, integración con otros sistemas o ganancia de rendimiento.
-
-## Formato predeterminado {#default-format}
-
-Si el `FORMAT` se omite la cláusula, se utiliza el formato predeterminado, que depende tanto de la configuración como de la interfaz utilizada para acceder al servidor ClickHouse. Para el [Interfaz HTTP](../../../interfaces/http.md) y el [cliente de línea de comandos](../../../interfaces/cli.md) En el modo batch, el formato predeterminado es `TabSeparated`. Para el cliente de línea de comandos en modo interactivo, el formato predeterminado es `PrettyCompact` (produce tablas compactas legibles por humanos).
-
-## Detalles de implementación {#implementation-details}
-
-Cuando se utiliza el cliente de línea de comandos, los datos siempre se pasan a través de la red en un formato interno eficiente (`Native`). El cliente interpreta independientemente el `FORMAT` cláusula de la consulta y formatea los datos en sí (aliviando así la red y el servidor de la carga adicional).

-# Cláusula FROM {#select-from}
-
-El `FROM` cláusula especifica la fuente de la que se leen los datos:
-
--   [Tabla](../../../engines/table-engines/index.md)
--   [Subconsultas](index.md) {## TODO: mejor enlace ##}
--   [Función de la tabla](../../table-functions/index.md#table-functions)
-
-[JOIN](join.md) y [ARRAY JOIN](array-join.md) también pueden utilizarse para ampliar la funcionalidad del `FROM` clausula.
-
-La subconsulta es otra `SELECT` consulta que se puede especificar entre paréntesis dentro `FROM` clausula.
-
-`FROM` cláusula puede contener múltiples fuentes de datos, separadas por comas, que es equivalente a realizar [CROSS JOIN](join.md) en ellos.
-
-## Modificador FINAL {#select-from-final}
-
-Cuando `FINAL` se especifica, ClickHouse fusiona completamente los datos antes de devolver el resultado y, por lo tanto, realiza todas las transformaciones de datos que ocurren durante las fusiones para el motor de tabla dado.
-
-Es aplicable cuando se seleccionan datos de tablas que utilizan [Método de codificación de datos:](../../../engines/table-engines/mergetree-family/mergetree.md)- familia del motor (excepto `GraphiteMergeTree`). También soportado para:
-
--   [Replicado](../../../engines/table-engines/mergetree-family/replication.md) versiones de `MergeTree` motor.
--   [Vista](../../../engines/table-engines/special/view.md), [Búfer](../../../engines/table-engines/special/buffer.md), [Distribuido](../../../engines/table-engines/special/distributed.md), y [Método de codificación de datos:](../../../engines/table-engines/special/materializedview.md) motores que funcionan sobre otros motores, siempre que se hayan creado sobre `MergeTree`-mesas de motor.
-
-### Inconveniente {#drawbacks}
-
-Consultas que usan `FINAL` se ejecutan no tan rápido como consultas similares que no lo hacen, porque:
-
--   La consulta se ejecuta en un solo subproceso y los datos se combinan durante la ejecución de la consulta.
--   Consultas con `FINAL` leer columnas de clave primaria además de las columnas especificadas en la consulta.
-
-**En la mayoría de los casos, evite usar `FINAL`.** El enfoque común es utilizar diferentes consultas que asumen los procesos en segundo plano de la `MergeTree` el motor aún no ha sucedido y tratar con él mediante la aplicación de agregación (por ejemplo, para descartar duplicados). {## TODO: ejemplos ##}
-
-## Detalles de implementación {#implementation-details}
-
-Si el `FROM` se omite la cláusula, los datos se leerán desde el `system.one` tabla.
-El `system.one` table contiene exactamente una fila (esta tabla cumple el mismo propósito que la tabla DUAL que se encuentra en otros DBMS).
-
-Para ejecutar una consulta, todas las columnas enumeradas en la consulta se extraen de la tabla adecuada. Las columnas no necesarias para la consulta externa se eliminan de las subconsultas.
-Si una consulta no muestra ninguna columnas (por ejemplo, `SELECT count() FROM t`), alguna columna se extrae de la tabla de todos modos (se prefiere la más pequeña), para calcular el número de filas.

-# GRUPO POR Cláusula {#select-group-by-clause}
-
-`GROUP BY` cláusula cambia el `SELECT` consulta en un modo de agregación, que funciona de la siguiente manera:
-
--   `GROUP BY` clause contiene una lista de expresiones (o una sola expresión, que se considera la lista de longitud uno). Esta lista actúa como un “grouping key”, mientras que cada expresión individual será referida como un “key expressions”.
--   Todas las expresiones en el [SELECT](index.md), [HAVING](having.md), y [ORDER BY](order-by.md) clausula **deber** se calculará basándose en expresiones clave **o** en [funciones agregadas](../../../sql-reference/aggregate-functions/index.md) sobre expresiones no clave (incluidas columnas simples). En otras palabras, cada columna seleccionada de la tabla debe usarse en una expresión clave o dentro de una función agregada, pero no en ambas.
--   Resultado de la agregación `SELECT` la consulta contendrá tantas filas como valores únicos de “grouping key” en la tabla de origen. Por lo general, esto reduce significativamente el recuento de filas, a menudo en órdenes de magnitud, pero no necesariamente: el recuento de filas se mantiene igual si todo “grouping key” los valores fueron distintos.
-
-!!! note "Nota"
-    Hay una forma adicional de ejecutar la agregación sobre una tabla. Si una consulta contiene columnas de tabla solo dentro de funciones agregadas, el `GROUP BY clause` se puede omitir, y se asume la agregación por un conjunto vacío de claves. Tales consultas siempre devuelven exactamente una fila.
-
-## Procesamiento NULL {#null-processing}
-
-Para agrupar, ClickHouse interpreta [NULL](../../syntax.md#null-literal) como valor, y `NULL==NULL`. Se diferencia de `NULL` procesamiento en la mayoría de los otros contextos.
-
-Aquí hay un ejemplo para mostrar lo que esto significa.
-
-Supongamos que tienes esta tabla:
-
-``` text
-┌─x─┬────y─┐
-│ 1 │    2 │
-│ 2 │ ᴺᵁᴸᴸ │
-│ 3 │    2 │
-│ 3 │    3 │
-│ 3 │ ᴺᵁᴸᴸ │
-└───┴──────┘
-```
-
-Consulta `SELECT sum(x), y FROM t_null_big GROUP BY y` resultados en:
-
-``` text
-┌─sum(x)─┬────y─┐
-│      4 │    2 │
-│      3 │    3 │
-│      5 │ ᴺᵁᴸᴸ │
-└────────┴──────┘
-```
-
-Se puede ver que `GROUP BY` para `y = NULL` resumir `x` como si `NULL` es este valor.
-
-Si pasa varias teclas a `GROUP BY` el resultado le dará todas las combinaciones de la selección, como si `NULL` fueron un valor específico.
-
-## CON TOTALS Modificador {#with-totals-modifier}
-
-Si el `WITH TOTALS` se especifica el modificador, se calculará otra fila. Esta fila tendrá columnas clave que contienen valores predeterminados (zeros o líneas vacías) y columnas de funciones agregadas con los valores calculados en todas las filas (el “total” valor).
-
-Esta fila adicional solo se produce en `JSON*`, `TabSeparated*`, y `Pretty*` formatos, por separado de las otras filas:
-
--   En `JSON*` formatos, esta fila se muestra como una ‘totals’ campo.
--   En `TabSeparated*` formatea, la fila viene después del resultado principal, precedida por una fila vacía (después de los otros datos).
--   En `Pretty*` formatea, la fila se muestra como una tabla separada después del resultado principal.
--   En los otros formatos no está disponible.
-
-`WITH TOTALS` se puede ejecutar de diferentes maneras cuando HAVING está presente. El comportamiento depende de la ‘totals_mode’ configuración.
-
-### Configuración del procesamiento de totales {#configuring-totals-processing}
-
-Predeterminada, `totals_mode = 'before_having'`. En este caso, ‘totals’ se calcula en todas las filas, incluidas las que no pasan por HAVING y `max_rows_to_group_by`.
-
-Las otras alternativas incluyen solo las filas que pasan por HAVING en ‘totals’, y comportarse de manera diferente con el ajuste `max_rows_to_group_by` y `group_by_overflow_mode = 'any'`.
-
-`after_having_exclusive` – Don't include rows that didn't pass through `max_rows_to_group_by`. En otras palabras, ‘totals’ tendrá menos o el mismo número de filas que si `max_rows_to_group_by` se omitieron.
-
-`after_having_inclusive` – Include all the rows that didn't pass through ‘max_rows_to_group_by’ en ‘totals’. En otras palabras, ‘totals’ tendrá más o el mismo número de filas como lo haría si `max_rows_to_group_by` se omitieron.
-
-`after_having_auto` – Count the number of rows that passed through HAVING. If it is more than a certain amount (by default, 50%), include all the rows that didn't pass through ‘max_rows_to_group_by’ en ‘totals’. De lo contrario, no los incluya.
-
-`totals_auto_threshold` – By default, 0.5. The coefficient for `after_having_auto`.
-
-Si `max_rows_to_group_by` y `group_by_overflow_mode = 'any'` no se utilizan, todas las variaciones de `after_having` son los mismos, y se puede utilizar cualquiera de ellos (por ejemplo, `after_having_auto`).
-
-Puede usar WITH TOTALS en subconsultas, incluidas las subconsultas en la cláusula JOIN (en este caso, se combinan los valores totales respectivos).
-
-## Ejemplos {#examples}
-
-Ejemplo:
-
-``` sql
-SELECT
-    count(),
-    median(FetchTiming > 60 ? 60 : FetchTiming),
-    count() - sum(Refresh)
-FROM hits
-```
-
-Sin embargo, a diferencia del SQL estándar, si la tabla no tiene ninguna fila (o no hay ninguna, o no hay ninguna después de usar WHERE para filtrar), se devuelve un resultado vacío, y no el resultado de una de las filas que contienen los valores iniciales de las funciones agregadas.
-
-A diferencia de MySQL (y conforme a SQL estándar), no puede obtener algún valor de alguna columna que no esté en una función clave o agregada (excepto expresiones constantes). Para evitar esto, puede usar el ‘any’ función de agregado (obtener el primer valor encontrado) o ‘min/max’.
-
-Ejemplo:
-
-``` sql
-SELECT
-    domainWithoutWWW(URL) AS domain,
-    count(),
-    any(Title) AS title -- getting the first occurred page header for each domain.
-FROM hits
-GROUP BY domain
-```
-
-Para cada valor de clave diferente encontrado, GROUP BY calcula un conjunto de valores de función agregados.
-
-GROUP BY no se admite para columnas de matriz.
-
-No se puede especificar una constante como argumentos para funciones agregadas. Ejemplo: sum(1). En lugar de esto, puedes deshacerte de la constante. Ejemplo: `count()`.
-
-## Detalles de implementación {#implementation-details}
-
-La agregación es una de las características más importantes de un DBMS orientado a columnas, y por lo tanto su implementación es una de las partes más optimizadas de ClickHouse. De forma predeterminada, la agregación se realiza en la memoria utilizando una tabla hash. Tiene más de 40 especializaciones que se eligen automáticamente dependiendo de “grouping key” tipos de datos.
-
-### GROUP BY en memoria externa {#select-group-by-in-external-memory}
-
-Puede habilitar el volcado de datos temporales en el disco para restringir el uso de memoria durante `GROUP BY`.
-El [max_bytes_before_external_group_by](../../../operations/settings/settings.md#settings-max_bytes_before_external_group_by) determina el umbral de consumo de RAM para el dumping `GROUP BY` datos temporales al sistema de archivos. Si se establece en 0 (el valor predeterminado), está deshabilitado.
-
-Cuando se utiliza `max_bytes_before_external_group_by`, le recomendamos que establezca `max_memory_usage` aproximadamente el doble de alto. Esto es necesario porque hay dos etapas para la agregación: leer los datos y formar datos intermedios (1) y fusionar los datos intermedios (2). El volcado de datos al sistema de archivos solo puede ocurrir durante la etapa 1. Si los datos temporales no se volcaron, entonces la etapa 2 puede requerir hasta la misma cantidad de memoria que en la etapa 1.
-
-Por ejemplo, si [Método de codificación de datos:](../../../operations/settings/settings.md#settings_max_memory_usage) se estableció en 10000000000 y desea usar agregación externa, tiene sentido establecer `max_bytes_before_external_group_by` a 10000000000, y `max_memory_usage` a 20000000000. Cuando se activa la agregación externa (si hubo al menos un volcado de datos temporales), el consumo máximo de RAM es solo un poco más que `max_bytes_before_external_group_by`.
-
-Con el procesamiento de consultas distribuidas, la agregación externa se realiza en servidores remotos. Para que el servidor solicitante use solo una pequeña cantidad de RAM, establezca `distributed_aggregation_memory_efficient` a 1.
-
-Al fusionar datos en el disco, así como al fusionar resultados de servidores remotos cuando `distributed_aggregation_memory_efficient` la configuración está habilitada, consume hasta `1/256 * the_number_of_threads` de la cantidad total de RAM.
-
-Cuando la agregación externa está habilitada, si `max_bytes_before_external_group_by` of data (i.e. data was not flushed), the query runs just as fast as without external aggregation. If any temporary data was flushed, the run time will be several times longer (approximately three times).
-
-Si usted tiene un [ORDER BY](order-by.md) con un [LIMIT](limit.md) despues `GROUP BY`, entonces la cantidad de RAM usada depende de la cantidad de datos en `LIMIT`, no en toda la tabla. Pero si el `ORDER BY` no tiene `LIMIT`, no se olvide de habilitar la clasificación externa (`max_bytes_before_external_sort`).

-# Cláusula HAVING {#having-clause}
-
-Permite filtrar los resultados de agregación producidos por [GROUP BY](group-by.md). Es similar a la [WHERE](where.md) cláusula, pero la diferencia es que `WHERE` se realiza antes de la agregación, mientras que `HAVING` se realiza después de eso.
-

-
-## SELECT Cláusula {#select-clause}
-
-[Expresiones](../../syntax.md#syntax-expressions) especificado en el `SELECT` cláusula se calculan después de que todas las operaciones en las cláusulas descritas anteriormente hayan finalizado. Estas expresiones funcionan como si se aplicaran a filas separadas en el resultado. Si las expresiones en el `SELECT` cláusula contiene funciones agregadas, a continuación, ClickHouse procesa funciones agregadas y expresiones utilizadas como sus argumentos durante el [GROUP BY](group-by.md) agregación.
-
-Si desea incluir todas las columnas en el resultado, use el asterisco (`*`) simbolo. Por ejemplo, `SELECT * FROM ...`.
-
-Para hacer coincidir algunas columnas en el resultado con un [Re2](https://en.wikipedia.org/wiki/RE2_(software)) expresión regular, puede utilizar el `COLUMNS` expresion.
-
-``` sql
-COLUMNS('regexp')
-```
-
-Por ejemplo, considere la tabla:
-
-``` sql
-CREATE TABLE default.col_names (aa Int8, ab Int8, bc Int8) ENGINE = TinyLog
-```
-
-La siguiente consulta selecciona datos de todas las columnas que contienen `a` símbolo en su nombre.
-
-``` sql
-SELECT COLUMNS('a') FROM col_names
-```
-
-``` text
-┌─aa─┬─ab─┐
-│  1 │  1 │
-└────┴────┘
-```
-
-Las columnas seleccionadas no se devuelven en orden alfabético.
-
-Puede utilizar múltiples `COLUMNS` expresiones en una consulta y aplicarles funciones.
-
-Por ejemplo:
-
-``` sql
-SELECT COLUMNS('a'), COLUMNS('c'), toTypeName(COLUMNS('c')) FROM col_names
-```
-
-``` text
-┌─aa─┬─ab─┬─bc─┬─toTypeName(bc)─┐
-│  1 │  1 │  1 │ Int8           │
-└────┴────┴────┴────────────────┘
-```
-
-Cada columna devuelta por el `COLUMNS` expresión se pasa a la función como un argumento separado. También puede pasar otros argumentos a la función si los admite. Tenga cuidado al usar funciones. Si una función no admite la cantidad de argumentos que le ha pasado, ClickHouse lanza una excepción.
-
-Por ejemplo:
-
-``` sql
-SELECT COLUMNS('a') + COLUMNS('c') FROM col_names
-```
-
-``` text
-Received exception from server (version 19.14.1):
-Code: 42. DB::Exception: Received from localhost:9000. DB::Exception: Number of arguments for function plus doesn't match: passed 3, should be 2.
-```
-
-En este ejemplo, `COLUMNS('a')` devuelve dos columnas: `aa` y `ab`. `COLUMNS('c')` devuelve el `bc` columna. El `+` el operador no puede aplicar a 3 argumentos, por lo que ClickHouse lanza una excepción con el mensaje relevante.
-
-Columnas que coinciden con el `COLUMNS` expresión puede tener diferentes tipos de datos. Si `COLUMNS` no coincide con ninguna columna y es la única expresión en `SELECT`, ClickHouse lanza una excepción.
-
-### Asterisco {#asterisk}
-
-Puede poner un asterisco en cualquier parte de una consulta en lugar de una expresión. Cuando se analiza la consulta, el asterisco se expande a una lista de todas las columnas de la tabla `MATERIALIZED` y `ALIAS` columna). Solo hay unos pocos casos en los que se justifica el uso de un asterisco:
-
--   Al crear un volcado de tabla.
--   Para tablas que contienen solo unas pocas columnas, como las tablas del sistema.
--   Para obtener información sobre qué columnas están en una tabla. En este caso, establezca `LIMIT 1`. Pero es mejor usar el `DESC TABLE` consulta.
--   Cuando hay una filtración fuerte en un pequeño número de columnas usando `PREWHERE`.
--   En subconsultas (ya que las columnas que no son necesarias para la consulta externa están excluidas de las subconsultas).
-
-En todos los demás casos, no recomendamos usar el asterisco, ya que solo le da los inconvenientes de un DBMS columnar en lugar de las ventajas. En otras palabras, no se recomienda usar el asterisco.
-
-### Valores extremos {#extreme-values}
-
-Además de los resultados, también puede obtener valores mínimos y máximos para las columnas de resultados. Para hacer esto, establezca el **extremo** a 1. Los mínimos y máximos se calculan para tipos numéricos, fechas y fechas con horas. Para otras columnas, se generan los valores predeterminados.
-
-An extra two rows are calculated – the minimums and maximums, respectively. These extra two rows are output in `JSON*`, `TabSeparated*`, y `Pretty*` [formato](../../../interfaces/formats.md), separado de las otras filas. No se emiten para otros formatos.
-
-En `JSON*` los valores extremos se emiten en un formato separado. ‘extremes’ campo. En `TabSeparated*` , la fila viene después del resultado principal, y después de ‘totals’ si está presente. Está precedido por una fila vacía (después de los otros datos). En `Pretty*` formatea, la fila se muestra como una tabla separada después del resultado principal, y después de `totals` si está presente.
-
-Los valores extremos se calculan para las filas anteriores `LIMIT`, pero después `LIMIT BY`. Sin embargo, cuando se usa `LIMIT offset, size`, las filas antes `offset` están incluidos en `extremes`. En las solicitudes de secuencia, el resultado también puede incluir un pequeño número de filas que pasaron por `LIMIT`.
-
-### Nota {#notes}
-
-Puedes usar sinónimos (`AS` aliases) en cualquier parte de una consulta.
-
-El `GROUP BY` y `ORDER BY` las cláusulas no admiten argumentos posicionales. Esto contradice MySQL, pero se ajusta al SQL estándar. Por ejemplo, `GROUP BY 1, 2` will be interpreted as grouping by constants (i.e. aggregation of all rows into one).
-
-## Detalles de implementación {#implementation-details}
-
-Si la consulta omite el `DISTINCT`, `GROUP BY` y `ORDER BY` cláusulas y el `IN` y `JOIN` subconsultas, la consulta se procesará por completo, utilizando O (1) cantidad de RAM. De lo contrario, la consulta podría consumir mucha RAM si no se especifican las restricciones adecuadas:
-
--   `max_memory_usage`
--   `max_rows_to_group_by`
--   `max_rows_to_sort`
--   `max_rows_in_distinct`
--   `max_bytes_in_distinct`
--   `max_rows_in_set`
--   `max_bytes_in_set`
--   `max_rows_in_join`
--   `max_bytes_in_join`
--   `max_bytes_before_external_sort`
--   `max_bytes_before_external_group_by`
-
-Para obtener más información, consulte la sección “Settings”. Es posible utilizar la clasificación externa (guardar tablas temporales en un disco) y la agregación externa.

-# Cláusula JOIN {#select-join}
-
-Join produce una nueva tabla combinando columnas de una o varias tablas utilizando valores comunes a cada una. Es una operación común en bases de datos con soporte SQL, que corresponde a [álgebra relacional](https://en.wikipedia.org/wiki/Relational_algebra#Joins_and_join-like_operators) unir. El caso especial de una combinación de tabla a menudo se conoce como “self-join”.
-
-Sintaxis:
-
-``` sql
-SELECT <expr_list>
-FROM <left_table>
-[GLOBAL] [INNER|LEFT|RIGHT|FULL|CROSS] [OUTER|SEMI|ANTI|ANY|ASOF] JOIN <right_table>
-(ON <expr_list>)|(USING <column_list>) ...
-```
-
-Expresiones de `ON` y columnas de `USING` cláusula se llaman “join keys”. A menos que se indique lo contrario, join produce un [Producto cartesiano](https://en.wikipedia.org/wiki/Cartesian_product) de filas con coincidencia “join keys”, lo que podría producir resultados con muchas más filas que las tablas de origen.
-
-## Tipos admitidos de JOIN {#select-join-types}
-
-Todo estándar [SQL JOIN](https://en.wikipedia.org/wiki/Join_(SQL)) tipos son compatibles:
-
--   `INNER JOIN`, sólo se devuelven las filas coincidentes.
--   `LEFT OUTER JOIN`, filas no coincidentes de la tabla izquierda se devuelven además de las filas coincidentes.
--   `RIGHT OUTER JOIN`, filas no coincidentes de la tabla izquierda se devuelven además de las filas coincidentes.
--   `FULL OUTER JOIN`, las filas que no coinciden de ambas tablas se devuelven además de las filas coincidentes.
--   `CROSS JOIN`, produce el producto cartesiano de tablas enteras, “join keys” ser **ni** indicado.
-
-`JOIN` sin tipo especificado implica `INNER`. Palabra clave `OUTER` se puede omitir con seguridad. Sintaxis alternativa para `CROSS JOIN` está especificando múltiples tablas en [Cláusula FROM](from.md) separados por comas.
-
-Tipos de unión adicionales disponibles en ClickHouse:
-
--   `LEFT SEMI JOIN` y `RIGHT SEMI JOIN`, una lista blanca en “join keys”, sin producir un producto cartesiano.
--   `LEFT ANTI JOIN` y `RIGHT ANTI JOIN`, una lista negra sobre “join keys”, sin producir un producto cartesiano.
--   `LEFT ANY JOIN`, `RIGHT ANY JOIN` and `INNER ANY JOIN`, partially (for opposite side of `LEFT` and `RIGHT`) or completely (for `INNER` and `FULL`) disables the cartesian product for standard `JOIN` types.
--   `ASOF JOIN` and `LEFT ASOF JOIN`, joining sequences with a non-exact match. `ASOF JOIN` usage is described below.
-
-## Setting {#join-settings}
-
-!!! note "Nota"
-    El valor de rigor predeterminado se puede anular usando [Por favor, introduzca su dirección de correo electrónico](../../../operations/settings/settings.md#settings-join_default_strictness) configuración.
-
-### ASOF JOIN Uso {#asof-join-usage}
-
-`ASOF JOIN` es útil cuando necesita unir registros que no tienen una coincidencia exacta.
-
-Tablas para `ASOF JOIN` debe tener una columna de secuencia ordenada. Esta columna no puede estar sola en una tabla y debe ser uno de los tipos de datos: `UInt32`, `UInt64`, `Float32`, `Float64`, `Date`, y `DateTime`.
-
-Sintaxis `ASOF JOIN ... ON`:
-
-``` sql
-SELECT expressions_list
-FROM table_1
-ASOF LEFT JOIN table_2
-ON equi_cond AND closest_match_cond
-```
-
-Puede usar cualquier número de condiciones de igualdad y exactamente una condición de coincidencia más cercana. Por ejemplo, `SELECT count() FROM table_1 ASOF LEFT JOIN table_2 ON table_1.a == table_2.b AND table_2.t <= table_1.t`.
-
-Condiciones admitidas para la coincidencia más cercana: `>`, `>=`, `<`, `<=`.
-
-Sintaxis `ASOF JOIN ... USING`:
-
-``` sql
-SELECT expressions_list
-FROM table_1
-ASOF JOIN table_2
-USING (equi_column1, ... equi_columnN, asof_column)
-```
-
-`ASOF JOIN` utilizar `equi_columnX` para unirse a la igualdad y `asof_column` para unirse en el partido más cercano con el `table_1.asof_column >= table_2.asof_column` condición. El `asof_column` columna siempre el último en el `USING` clausula.
-
-Por ejemplo, considere las siguientes tablas:
-
-         table_1                           table_2
-      event   | ev_time | user_id       event   | ev_time | user_id
-    ----------|---------|----------   ----------|---------|----------
-                  ...                               ...
-    event_1_1 |  12:00  |  42         event_2_1 |  11:59  |   42
-                  ...                 event_2_2 |  12:30  |   42
-    event_1_2 |  13:00  |  42         event_2_3 |  13:00  |   42
-                  ...                               ...
-
-`ASOF JOIN` puede tomar la marca de tiempo de un evento de usuario de `table_1` y encontrar un evento en `table_2` donde la marca de tiempo es la más cercana a la marca de tiempo del evento `table_1` correspondiente a la condición de coincidencia más cercana. Los valores de marca de tiempo iguales son los más cercanos si están disponibles. Aquí, el `user_id` se puede utilizar para unirse a la igualdad y el `ev_time` columna se puede utilizar para unirse en el partido más cercano. En nuestro ejemplo, `event_1_1` se puede unir con `event_2_1` y `event_1_2` se puede unir con `event_2_3`, pero `event_2_2` no se puede unir.
-
-!!! note "Nota"
-    `ASOF` unirse es **ni** apoyado en el [Unir](../../../engines/table-engines/special/join.md) motor de mesa.
-
-## Unión distribuida {#global-join}
-
-Hay dos formas de ejecutar la unión que involucra tablas distribuidas:
-
--   Cuando se utiliza una normal `JOIN`, la consulta se envía a servidores remotos. Las subconsultas se ejecutan en cada una de ellas para crear la tabla correcta, y la unión se realiza con esta tabla. En otras palabras, la tabla correcta se forma en cada servidor por separado.
--   Cuando se utiliza `GLOBAL ... JOIN`, primero el servidor requestor ejecuta una subconsulta para calcular la tabla correcta. Esta tabla temporal se pasa a cada servidor remoto y las consultas se ejecutan en ellos utilizando los datos temporales que se transmitieron.
-
-Tenga cuidado al usar `GLOBAL`. Para obtener más información, consulte [Subconsultas distribuidas](../../operators/in.md#select-distributed-subqueries) apartado.
-
-## Recomendaciones de uso {#usage-recommendations}
-
-### Procesamiento de celdas vacías o NULL {#processing-of-empty-or-null-cells}
-
-Al unir tablas, pueden aparecer las celdas vacías. Configuración [Sistema abierto.](../../../operations/settings/settings.md#join_use_nulls) definir cómo ClickHouse llena estas celdas.
-
-Si el `JOIN` las llaves son [NULL](../../data-types/nullable.md) campos, las filas donde al menos una de las claves tiene el valor [NULL](../../../sql-reference/syntax.md#null-literal) no se unen.
-
-### Sintaxis {#syntax}
-
-Las columnas especificadas en `USING` debe tener los mismos nombres en ambas subconsultas, y las otras columnas deben tener un nombre diferente. Puede utilizar alias para cambiar los nombres de las columnas en subconsultas.
-
-El `USING` clause especifica una o más columnas a unir, lo que establece la igualdad de estas columnas. La lista de columnas se establece sin corchetes. No se admiten condiciones de unión más complejas.
-
-### Limitaciones de sintaxis {#syntax-limitations}
-
-Para múltiples `JOIN` cláusulas en una sola `SELECT` consulta:
-
--   Tomando todas las columnas a través de `*` está disponible solo si se unen tablas, no subconsultas.
--   El `PREWHERE` cláusula no está disponible.
-
-Para `ON`, `WHERE`, y `GROUP BY` clausula:
-
--   Las expresiones arbitrarias no se pueden utilizar en `ON`, `WHERE`, y `GROUP BY` cláusulas, pero puede definir una expresión en un `SELECT` cláusula y luego usarla en estas cláusulas a través de un alias.
-
-### Rendimiento {#performance}
-
-Cuando se ejecuta un `JOIN`, no hay optimización del orden de ejecución en relación con otras etapas de la consulta. La combinación (una búsqueda en la tabla de la derecha) se ejecuta antes de filtrar `WHERE` y antes de la agregación.
-
-Cada vez que se ejecuta una consulta `JOIN`, la subconsulta se ejecuta de nuevo porque el resultado no se almacena en caché. Para evitar esto, use el especial [Unir](../../../engines/table-engines/special/join.md) motor de tabla, que es una matriz preparada para unirse que siempre está en RAM.
-
-En algunos casos, es más eficiente de usar [IN](../../operators/in.md) en lugar de `JOIN`.
-
-Si necesita un `JOIN` para unirse a tablas de dimensión (son tablas relativamente pequeñas que contienen propiedades de dimensión, como nombres para campañas publicitarias), un `JOIN` podría no ser muy conveniente debido al hecho de que se vuelve a acceder a la tabla correcta para cada consulta. Para tales casos, hay un “external dictionaries” característica que debe utilizar en lugar de `JOIN`. Para obtener más información, consulte [Diccionarios externos](../../dictionaries/external-dictionaries/external-dicts.md) apartado.
-
-### Limitaciones de memoria {#memory-limitations}
-
-De forma predeterminada, ClickHouse usa el [hash unirse](https://en.wikipedia.org/wiki/Hash_join) algoritmo. ClickHouse toma el `<right_table>` y crea una tabla hash para ello en RAM. Después de algún umbral de consumo de memoria, ClickHouse vuelve a fusionar el algoritmo de unión.
-
-Si necesita restringir el consumo de memoria de la operación de unión, use la siguiente configuración:
-
--   [Método de codificación de datos:](../../../operations/settings/query-complexity.md#settings-max_rows_in_join) — Limits number of rows in the hash table.
--   [Método de codificación de datos:](../../../operations/settings/query-complexity.md#settings-max_bytes_in_join) — Limits size of the hash table.
-
-Cuando se alcanza cualquiera de estos límites, ClickHouse actúa como el [join_overflow_mode](../../../operations/settings/query-complexity.md#settings-join_overflow_mode) configuración instruye.
-
-## Ejemplos {#examples}

-Ejemplo:
-
-``` sql
-SELECT
-    CounterID,
-    hits,

-# LIMITAR POR Cláusula {#limit-by-clause}
-
-Una consulta con el `LIMIT n BY expressions` cláusula selecciona la primera `n` para cada valor distinto de `expressions`. La clave para `LIMIT BY` puede contener cualquier número de [expresiones](../../syntax.md#syntax-expressions).
-
-ClickHouse admite las siguientes variantes de sintaxis:
-
--   `LIMIT [offset_value, ]n BY expressions`
--   `LIMIT n OFFSET offset_value BY expressions`
-
-Durante el procesamiento de consultas, ClickHouse selecciona los datos ordenados por clave de ordenación. La clave de ordenación se establece explícitamente utilizando un [ORDER BY](order-by.md) cláusula o implícitamente como una propiedad del motor de tablas. Entonces se aplica ClickHouse `LIMIT n BY expressions` y devuelve la primera `n` filas para cada combinación distinta de `expressions`. Si `OFFSET` se especifica, a continuación, para cada bloque de datos que pertenece a una combinación distinta de `expressions`, ClickHouse salta `offset_value` número de filas desde el principio del bloque y devuelve un máximo de `n` filas como resultado. Si `offset_value` es mayor que el número de filas en el bloque de datos, ClickHouse devuelve cero filas del bloque.
-
-!!! note "Nota"
-    `LIMIT BY` no está relacionado con [LIMIT](limit.md). Ambos se pueden usar en la misma consulta.
-
-## Ejemplos {#examples}

-# ORDEN POR CLÁUSULA {#select-order-by}
-
-El `ORDER BY` cláusula contiene una lista de expresiones, cada una de las cuales puede atribuirse con `DESC` (descendente) o `ASC` modificador (ascendente) que determina la dirección de clasificación. Si no se especifica la dirección, `ASC` se supone, por lo que generalmente se omite. La dirección de ordenación se aplica a una sola expresión, no a toda la lista. Ejemplo: `ORDER BY Visits DESC, SearchPhrase`
-
-Las filas que tienen valores idénticos para la lista de expresiones de clasificación se generan en un orden arbitrario, que también puede ser no determinista (diferente cada vez).
-Si se omite la cláusula ORDER BY, el orden de las filas tampoco está definido, y también puede ser no determinista.
-
-## Clasificación de valores especiales {#sorting-of-special-values}
-
-Hay dos enfoques para `NaN` y `NULL` orden de clasificación:
-
--   Por defecto o con el `NULLS LAST` modificador: primero los valores, luego `NaN`, entonces `NULL`.
--   Con el `NULLS FIRST` modificador: primero `NULL`, entonces `NaN`, luego otros valores.
-
-### Ejemplo {#example}

-└───┴──────┘
-```
-
-Cuando se ordenan los números de coma flotante, los NaN están separados de los otros valores. Independientemente del orden de clasificación, los NaN vienen al final. En otras palabras, para la clasificación ascendente se colocan como si fueran más grandes que todos los demás números, mientras que para la clasificación descendente se colocan como si fueran más pequeños que el resto.
-
-## Soporte de colación {#collation-support}
-
-Para ordenar por valores de cadena, puede especificar la intercalación (comparación). Ejemplo: `ORDER BY SearchPhrase COLLATE 'tr'` - para ordenar por palabra clave en orden ascendente, utilizando el alfabeto turco, insensible a mayúsculas y minúsculas, suponiendo que las cadenas están codificadas en UTF-8. COLLATE se puede especificar o no para cada expresión en ORDER BY de forma independiente. Si se especifica ASC o DESC, se especifica COLLATE después de él. Cuando se usa COLLATE, la clasificación siempre distingue entre mayúsculas y minúsculas.
-
-Solo recomendamos usar COLLATE para la clasificación final de un pequeño número de filas, ya que la clasificación con COLLATE es menos eficiente que la clasificación normal por bytes.
-
-## Detalles de implementación {#implementation-details}
-
-Menos RAM se utiliza si un pequeño suficiente [LIMIT](limit.md) se especifica además `ORDER BY`. De lo contrario, la cantidad de memoria gastada es proporcional al volumen de datos para clasificar. Para el procesamiento de consultas distribuidas, si [GROUP BY](group-by.md) se omite, la clasificación se realiza parcialmente en servidores remotos y los resultados se fusionan en el servidor solicitante. Esto significa que para la ordenación distribuida, el volumen de datos a ordenar puede ser mayor que la cantidad de memoria en un único servidor.
-
-Si no hay suficiente RAM, es posible realizar la clasificación en la memoria externa (creando archivos temporales en un disco). Utilice el ajuste `max_bytes_before_external_sort` para este propósito. Si se establece en 0 (el valor predeterminado), la ordenación externa está deshabilitada. Si está habilitada, cuando el volumen de datos a ordenar alcanza el número especificado de bytes, los datos recopilados se ordenan y se vuelcan en un archivo temporal. Después de leer todos los datos, todos los archivos ordenados se fusionan y se generan los resultados. Los archivos se escriben en el `/var/lib/clickhouse/tmp/` directorio en la configuración (de forma predeterminada, pero puede usar el `tmp_path` parámetro para cambiar esta configuración).
-
-La ejecución de una consulta puede usar más memoria que `max_bytes_before_external_sort`. Por este motivo, esta configuración debe tener un valor significativamente menor que `max_memory_usage`. Como ejemplo, si su servidor tiene 128 GB de RAM y necesita ejecutar una sola consulta, establezca `max_memory_usage` de hasta 100 GB, y `max_bytes_before_external_sort` para 80 GB.
-
-La clasificación externa funciona con mucha menos eficacia que la clasificación en RAM.

-# PREWHERE Cláusula {#prewhere-clause}
-
-Prewhere es una optimización para aplicar el filtrado de manera más eficiente. Está habilitado de forma predeterminada incluso si `PREWHERE` cláusula no se especifica explícitamente. Funciona moviendo automáticamente parte de [WHERE](where.md) condición a la etapa prewhere. El papel de `PREWHERE` cláusula es sólo para controlar esta optimización si usted piensa que usted sabe cómo hacerlo mejor de lo que sucede por defecto.
-
-Con la optimización prewhere, al principio solo se leen las columnas necesarias para ejecutar la expresión prewhere. Luego se leen las otras columnas que son necesarias para ejecutar el resto de la consulta, pero solo aquellos bloques donde está la expresión prewhere “true” al menos para algunas filas. Si hay muchos bloques donde la expresión prewhere es “false” para todas las filas y prewhere necesita menos columnas que otras partes de la consulta, esto a menudo permite leer muchos menos datos del disco para la ejecución de la consulta.
-
-## Control de Prewhere manualmente {#controlling-prewhere-manually}
-
-La cláusula tiene el mismo significado que la `WHERE` clausula. La diferencia radica en qué datos se leen de la tabla. Al controlar manualmente `PREWHERE` para las condiciones de filtración utilizadas por una minoría de las columnas de la consulta, pero que proporcionan una filtración de datos segura. Esto reduce el volumen de datos a leer.
-
-Una consulta puede especificar simultáneamente `PREWHERE` y `WHERE`. En este caso, `PREWHERE` preceder `WHERE`.
-
-Si el `optimize_move_to_prewhere` se establece en 0, heurística para mover automáticamente partes de expresiones de `WHERE` a `PREWHERE` están deshabilitados.
-
-## Limitacion {#limitations}
-
-`PREWHERE` sólo es compatible con tablas de la `*MergeTree` familia.

-# Cláusula SAMPLE {#select-sample-clause}
-
-El `SAMPLE` cláusula permite aproximadamente `SELECT` procesamiento de consultas.
-
-Cuando se habilita el muestreo de datos, la consulta no se realiza en todos los datos, sino solo en una cierta fracción de datos (muestra). Por ejemplo, si necesita calcular estadísticas para todas las visitas, es suficiente ejecutar la consulta en la fracción 1/10 de todas las visitas y luego multiplicar el resultado por 10.
-
-El procesamiento de consultas aproximado puede ser útil en los siguientes casos:
-
--   Cuando tiene requisitos de temporización estrictos (como \<100 ms) pero no puede justificar el costo de recursos de hardware adicionales para cumplirlos.
--   Cuando sus datos sin procesar no son precisos, la aproximación no degrada notablemente la calidad.
--   Los requisitos comerciales se centran en los resultados aproximados (por rentabilidad o para comercializar los resultados exactos a los usuarios premium).
-
-!!! note "Nota"
-    Sólo puede utilizar el muestreo con las tablas en el [Método de codificación de datos:](../../../engines/table-engines/mergetree-family/mergetree.md) familia, y sólo si la expresión de muestreo se especificó durante la creación de la tabla (ver [Motor MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table)).
-
-Las características del muestreo de datos se enumeran a continuación:
-
--   El muestreo de datos es un mecanismo determinista. El resultado de la misma `SELECT .. SAMPLE` la consulta es siempre la misma.
--   El muestreo funciona consistentemente para diferentes tablas. Para tablas con una sola clave de muestreo, una muestra con el mismo coeficiente siempre selecciona el mismo subconjunto de datos posibles. Por ejemplo, una muestra de ID de usuario toma filas con el mismo subconjunto de todos los ID de usuario posibles de diferentes tablas. Esto significa que puede utilizar el ejemplo en subconsultas [IN](../../operators/in.md) clausula. Además, puede unir muestras usando el [JOIN](join.md) clausula.
--   El muestreo permite leer menos datos de un disco. Tenga en cuenta que debe especificar la clave de muestreo correctamente. Para obtener más información, consulte [Creación de una tabla MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table).

-| `SAMPLE k`           | Aqui `k` es el número de 0 a 1.</br>La consulta se ejecuta en `k` de datos. Por ejemplo, `SAMPLE 0.1` ejecuta la consulta en el 10% de los datos. [Leer más](#select-sample-k)                                                                                                |
-| `SAMPLE n`           | Aqui `n` es un entero suficientemente grande.</br>La consulta se ejecuta en una muestra de al menos `n` filas (pero no significativamente más que esto). Por ejemplo, `SAMPLE 10000000` ejecuta la consulta en un mínimo de 10.000.000 de filas. [Leer más](#select-sample-n) |

-
-## SAMPLE K {#select-sample-k}
-
-Aqui `k` es el número de 0 a 1 (se admiten notaciones fraccionarias y decimales). Por ejemplo, `SAMPLE 1/2` o `SAMPLE 0.5`.
-
-En un `SAMPLE k` cláusula, la muestra se toma de la `k` de datos. El ejemplo se muestra a continuación:
-
-``` sql
-SELECT
-    Title,
-    count() * 10 AS PageViews
-FROM hits_distributed
-SAMPLE 0.1
-WHERE
-    CounterID = 34
-GROUP BY Title
-ORDER BY PageViews DESC LIMIT 1000
-```
-
-En este ejemplo, la consulta se ejecuta en una muestra de 0,1 (10%) de datos. Los valores de las funciones agregadas no se corrigen automáticamente, por lo que para obtener un resultado aproximado, el valor `count()` se multiplica manualmente por 10.
-
-## SAMPLE N {#select-sample-n}
-
-Aqui `n` es un entero suficientemente grande. Por ejemplo, `SAMPLE 10000000`.
-
-En este caso, la consulta se ejecuta en una muestra de al menos `n` filas (pero no significativamente más que esto). Por ejemplo, `SAMPLE 10000000` ejecuta la consulta en un mínimo de 10.000.000 de filas.
-
-Dado que la unidad mínima para la lectura de datos es un gránulo (su tamaño se establece mediante el `index_granularity` ajuste), tiene sentido establecer una muestra que es mucho más grande que el tamaño del gránulo.
-
-Cuando se utiliza el `SAMPLE n` cláusula, no sabe qué porcentaje relativo de datos se procesó. Por lo tanto, no sabe el coeficiente por el que se deben multiplicar las funciones agregadas. Utilice el `_sample_factor` columna virtual para obtener el resultado aproximado.
-
-El `_sample_factor` columna contiene coeficientes relativos que se calculan dinámicamente. Esta columna se crea automáticamente cuando [crear](../../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table) una tabla con la clave de muestreo especificada. Los ejemplos de uso del `_sample_factor` columna se muestran a continuación.
-
-Consideremos la tabla `visits`, que contiene las estadísticas sobre las visitas al sitio. El primer ejemplo muestra cómo calcular el número de páginas vistas:
-
-``` sql
-SELECT sum(PageViews * _sample_factor)
-FROM visits
-SAMPLE 10000000
-```
-
-El siguiente ejemplo muestra cómo calcular el número total de visitas:
-
-``` sql
-SELECT sum(_sample_factor)
-FROM visits
-SAMPLE 10000000
-```
-
-El siguiente ejemplo muestra cómo calcular la duración media de la sesión. Tenga en cuenta que no necesita usar el coeficiente relativo para calcular los valores promedio.
-
-``` sql
-SELECT avg(Duration)
-FROM visits
-SAMPLE 10000000
-```
-
-## SAMPLE K OFFSET M {#select-sample-offset}
-
-Aqui `k` y `m` son números del 0 al 1. Los ejemplos se muestran a continuación.
-
-**Ejemplo 1**
-
-``` sql
-SAMPLE 1/10
-```
-
-En este ejemplo, la muestra es 1/10 de todos los datos:
-
-`[++------------]`
-
-**Ejemplo 2**
-
-``` sql
-SAMPLE 1/10 OFFSET 1/2
-```
-
-Aquí, se toma una muestra del 10% de la segunda mitad de los datos.

-# UNION Cláusula {#union-clause}
-
-Usted puede utilizar `UNION ALL` combinar cualquier número de `SELECT` consultas extendiendo sus resultados. Ejemplo:
-
-``` sql
-SELECT CounterID, 1 AS table, toInt64(count()) AS c
-    FROM test.hits
-    GROUP BY CounterID
-
-UNION ALL
-
-SELECT CounterID, 2 AS table, sum(Sign) AS c
-    FROM test.visits
-    GROUP BY CounterID
-    HAVING c > 0
-```
-
-Las columnas de resultados coinciden con su índice (orden dentro `SELECT`). Si los nombres de columna no coinciden, los nombres del resultado final se toman de la primera consulta.
-
-La fundición de tipo se realiza para uniones. Por ejemplo, si dos consultas que se combinan tienen el mismo campo-`Nullable` y `Nullable` tipos de un tipo compatible, el resultado `UNION ALL` tiene una `Nullable` campo de tipo.
-
-Consultas que son parte de `UNION ALL` no se puede encerrar entre corchetes redondos. [ORDER BY](order-by.md) y [LIMIT](limit.md) se aplican a consultas separadas, no al resultado final. Si necesita aplicar una conversión al resultado final, puede colocar todas las consultas con `UNION ALL` en una subconsulta en el [FROM](from.md) clausula.
-
-## Limitacion {#limitations}
-
-Solo `UNION ALL` se admite. Regular `UNION` (`UNION DISTINCT`) no es compatible. Si necesita `UNION DISTINCT` usted puede escribir `SELECT DISTINCT` de una subconsulta que contiene `UNION ALL`.
-
-## Detalles de implementación {#implementation-details}
-
-Consultas que son parte de `UNION ALL` se puede ejecutar simultáneamente, y sus resultados se pueden mezclar juntos.

-# DONDE Cláusula {#select-where}
-
-`WHERE` cláusula permite filtrar los datos que provienen de [FROM](from.md) cláusula de `SELECT`.
-
-Si hay un `WHERE` cláusula, debe contener una expresión con el `UInt8` tipo. Esta suele ser una expresión con comparación y operadores lógicos. Las filas en las que esta expresión se evalúa como 0 se explican a partir de otras transformaciones o resultados.
-
-`WHERE` expresión se evalúa en la capacidad de utilizar índices y poda de partición, si el motor de tabla subyacente lo admite.
-
-!!! note "Nota"
-    Hay una optimización de filtrado llamada [preliminar](prewhere.md).

-# CON Cláusula {#with-clause}
-
-Esta sección proporciona soporte para expresiones de tabla común ([CTE](https://en.wikipedia.org/wiki/Hierarchical_and_recursive_queries_in_SQL)), por lo que los resultados de `WITH` cláusula se puede utilizar en el interior `SELECT` clausula.
-
-## Limitacion {#limitations}
-
-1.  No se admiten consultas recursivas.
-2.  Cuando se usa subconsulta dentro de la sección WITH , su resultado debe ser escalar con exactamente una fila.
-3.  Los resultados de la expresión no están disponibles en las subconsultas.
-
-## Ejemplos {#examples}
-
-**Ejemplo 1:** Usando expresión constante como “variable”
-
-``` sql
-WITH '2019-08-01 15:23:00' as ts_upper_bound
-SELECT *
-FROM hits
-WHERE
-    EventDate = toDate(ts_upper_bound) AND
-    EventTime <= ts_upper_bound
-```
-
-**Ejemplo 2:** Evictar el resultado de la expresión de sum (bytes) de la lista de columnas de la cláusula SELECT
-
-``` sql
-WITH sum(bytes) as s
-SELECT
-    formatReadableSize(s),
-    table
-FROM system.parts
-GROUP BY table
-ORDER BY s
-```
-
-**Ejemplo 3:** Uso de los resultados de la subconsulta escalar
-
-``` sql
-/* this example would return TOP 10 of most huge tables */
-WITH
-    (
-        SELECT sum(bytes)
-        FROM system.parts
-        WHERE active
-    ) AS total_disk_usage
-SELECT
-    (sum(bytes) / total_disk_usage) * 100 AS table_disk_usage,
-    table
-FROM system.parts
-GROUP BY table
-ORDER BY table_disk_usage DESC
-LIMIT 10
-```
-
-**Ejemplo 4:** Reutilización de la expresión en subconsulta
-
-Como solución alternativa para la limitación actual para el uso de expresiones en subconsultas, puede duplicarla.
-
-``` sql
-WITH ['hello'] AS hello
-SELECT
-    hello,
-    *
-FROM
-(
-    WITH ['hello'] AS hello
-    SELECT hello
-)
-```
-
-``` text
-┌─hello─────┬─hello─────┐
-│ ['hello'] │ ['hello'] │
-└───────────┴───────────┘

-## RELOAD DICTIONARIES {#query_language-system-reload-dictionaries}
-
-Vuelve a cargar todos los diccionarios que se han cargado correctamente antes.
-De forma predeterminada, los diccionarios se cargan perezosamente (ver [Diccionarios_lazy_load](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-dictionaries_lazy_load)), por lo que en lugar de cargarse automáticamente al inicio, se inicializan en el primer acceso a través de la función dictGet o SELECT desde tablas con ENGINE = Dictionary . El `SYSTEM RELOAD DICTIONARIES` consulta vuelve a cargar dichos diccionarios (LOADED).
-Siempre vuelve `Ok.` independientemente del resultado de la actualización del diccionario.
-
-## RELOAD DICTIONARY Dictionary_name {#query_language-system-reload-dictionary}
-
-Recarga completamente un diccionario `dictionary_name`, independientemente del estado del diccionario (LOADED / NOT_LOADED / FAILED).
-Siempre vuelve `Ok.` independientemente del resultado de la actualización del diccionario.
-El estado del diccionario se puede comprobar consultando el `system.dictionaries` tabla.
-
-``` sql
-SELECT name, status FROM system.dictionaries;
-```
-
-## DROP DNS CACHE {#query_language-system-drop-dns-cache}
-
-Restablece la caché DNS interna de ClickHouse. A veces (para versiones anteriores de ClickHouse) es necesario usar este comando al cambiar la infraestructura (cambiar la dirección IP de otro servidor de ClickHouse o el servidor utilizado por los diccionarios).
-
-Para obtener una administración de caché más conveniente (automática), consulte disable_internal_dns_cache, dns_cache_update_period parameters.
-
-## DROP MARK CACHE {#query_language-system-drop-mark-cache}
-
-Restablece la caché de marcas. Utilizado en el desarrollo de ClickHouse y pruebas de rendimiento.
-
-## FLUSH LOGS {#query_language-system-flush_logs}
-
-Flushes buffers of log messages to system tables (e.g. system.query_log). Allows you to not wait 7.5 seconds when debugging.
-
-## RELOAD CONFIG {#query_language-system-reload-config}
-
-Vuelve a cargar la configuración de ClickHouse. Se usa cuando la configuración se almacena en ZooKeeeper.
-
-## SHUTDOWN {#query_language-system-shutdown}
-
-Normalmente se apaga ClickHouse (como `service clickhouse-server stop` / `kill {$pid_clickhouse-server}`)
-
-## KILL {#query_language-system-kill}
-
-Anula el proceso de ClickHouse (como `kill -9 {$ pid_clickhouse-server}`)
-
-## Administración de tablas distribuidas {#query-language-system-distributed}
-
-ClickHouse puede administrar [distribuido](../../engines/table-engines/special/distributed.md) tabla. Cuando un usuario inserta datos en estas tablas, ClickHouse primero crea una cola de los datos que se deben enviar a los nodos del clúster y, a continuación, los envía de forma asincrónica. Puede administrar el procesamiento de colas con el [STOP DISTRIBUTED SENDS](#query_language-system-stop-distributed-sends), [FLUSH DISTRIBUTED](#query_language-system-flush-distributed), y [START DISTRIBUTED SENDS](#query_language-system-start-distributed-sends) consulta. También puede insertar sincrónicamente datos distribuidos con el `insert_distributed_sync` configuración.
-
-### STOP DISTRIBUTED SENDS {#query_language-system-stop-distributed-sends}
-
-Deshabilita la distribución de datos en segundo plano al insertar datos en tablas distribuidas.
-
-``` sql
-SYSTEM STOP DISTRIBUTED SENDS [db.]<distributed_table_name>
-```
-
-### FLUSH DISTRIBUTED {#query_language-system-flush-distributed}
-
-Obliga a ClickHouse a enviar datos a nodos de clúster de forma sincrónica. Si algún nodo no está disponible, ClickHouse produce una excepción y detiene la ejecución de la consulta. Puede volver a intentar la consulta hasta que tenga éxito, lo que sucederá cuando todos los nodos estén nuevamente en línea.
-
-``` sql
-SYSTEM FLUSH DISTRIBUTED [db.]<distributed_table_name>
-```
-
-### START DISTRIBUTED SENDS {#query_language-system-start-distributed-sends}
-
-Habilita la distribución de datos en segundo plano al insertar datos en tablas distribuidas.
-
-``` sql
-SYSTEM START DISTRIBUTED SENDS [db.]<distributed_table_name>
-```
-
-### STOP MERGES {#query_language-system-stop-merges}
-
-Proporciona la posibilidad de detener las fusiones en segundo plano para las tablas de la familia MergeTree:
-
-``` sql
-SYSTEM STOP MERGES [[db.]merge_tree_family_table_name]
-```
-
-!!! note "Nota"
-    `DETACH / ATTACH` la tabla comenzará las fusiones de fondo para la tabla, incluso en caso de que las fusiones se hayan detenido para todas las tablas MergeTree antes.
-
-### START MERGES {#query_language-system-start-merges}
-
-Proporciona la posibilidad de iniciar fusiones en segundo plano para tablas de la familia MergeTree:
-
-``` sql
-SYSTEM START MERGES [[db.]merge_tree_family_table_name]
-```

----
-
-# Sintaxis {#syntax}
-
-Hay dos tipos de analizadores en el sistema: el analizador SQL completo (un analizador de descenso recursivo) y el analizador de formato de datos (un analizador de flujo rápido).
-En todos los casos, excepto el `INSERT` consulta, sólo se utiliza el analizador SQL completo.
-El `INSERT` consulta utiliza ambos analizadores:
-
-``` sql
-INSERT INTO t VALUES (1, 'Hello, world'), (2, 'abc'), (3, 'def')
-```
-
-El `INSERT INTO t VALUES` fragmento es analizado por el analizador completo, y los datos `(1, 'Hello, world'), (2, 'abc'), (3, 'def')` es analizado por el analizador de flujo rápido. También puede activar el analizador completo de los datos mediante el [input_format_values_interpret_expressions](../operations/settings/settings.md#settings-input_format_values_interpret_expressions) configuración. Cuando `input_format_values_interpret_expressions = 1`, ClickHouse primero intenta analizar valores con el analizador de flujo rápido. Si falla, ClickHouse intenta usar el analizador completo para los datos, tratándolo como un SQL [expresion](#syntax-expressions).
-
-Los datos pueden tener cualquier formato. Cuando se recibe una consulta, el servidor no calcula más de [max_query_size](../operations/settings/settings.md#settings-max_query_size) bytes de la solicitud en RAM (por defecto, 1 MB), y el resto se analiza la secuencia.
-Permite evitar problemas con grandes `INSERT` consulta.
-
-Cuando se utiliza el `Values` formato en un `INSERT` consulta, puede parecer que los datos se analizan igual que las expresiones en un `SELECT` consulta, pero esto no es cierto. El `Values` formato es mucho más limitado.
-
-El resto de este artículo cubre el analizador completo. Para obtener más información sobre los analizadores de formato, consulte [Formato](../interfaces/formats.md) apartado.
-
-## Espacio {#spaces}
-
-Puede haber cualquier número de símbolos de espacio entre las construcciones sintácticas (incluidos el principio y el final de una consulta). Los símbolos de espacio incluyen el espacio, tabulación, avance de línea, CR y avance de formulario.
-
-## Comentario {#comments}
-
-ClickHouse admite comentarios de estilo SQL y de estilo C.
-Los comentarios de estilo SQL comienzan con `--` y continuar hasta el final de la línea, un espacio después `--` se puede omitir.
-C-estilo son de `/*` a `*/`y puede ser multilínea, tampoco se requieren espacios.
-
-## Palabras clave {#syntax-keywords}
-
-Las palabras clave no distinguen entre mayúsculas y minúsculas cuando corresponden a:
-
--   Estándar SQL. Por ejemplo, `SELECT`, `select` y `SeLeCt` son todos válidos.
--   Implementación en algunos DBMS populares (MySQL o Postgres). Por ejemplo, `DateTime` es lo mismo que `datetime`.
-
-Si el nombre del tipo de datos distingue entre mayúsculas y minúsculas `system.data_type_families` tabla.
-
-A diferencia de SQL estándar, todas las demás palabras clave (incluidos los nombres de funciones) son **minúsculas**.
-
-Las palabras clave no están reservadas; se tratan como tales solo en el contexto correspondiente. Si usted usa [identificador](#syntax-identifiers) con el mismo nombre que las palabras clave, encerrarlas en comillas dobles o backticks. Por ejemplo, la consulta `SELECT "FROM" FROM table_name` es válido si la tabla `table_name` tiene columna con el nombre `"FROM"`.
-
-## Identificador {#syntax-identifiers}
-
-Los identificadores son:
-
--   Nombres de clúster, base de datos, tabla, partición y columna.
--   Función.
--   Tipos de datos.
--   [Alias de expresión](#syntax-expression_aliases).
-
-Los identificadores pueden ser citados o no citados. Este último es preferido.
-
-Los identificadores no citados deben coincidir con la expresión regular `^[a-zA-Z_][0-9a-zA-Z_]*$` y no puede ser igual a [Palabras clave](#syntax-keywords). Ejemplos: `x, _1, X_y__Z123_.`
-
-Si desea utilizar identificadores iguales a las palabras clave o si desea utilizar otros símbolos en los identificadores, cítelo con comillas dobles o retrocesos, por ejemplo, `"id"`, `` `id` ``.
-
-## Literal {#literals}
-
-Hay numérico, cadena, compuesto, y `NULL` literal.
-
-### Numérico {#numeric}
-
-Literal numérico, intenta ser analizado:
-
--   Primero, como un número firmado de 64 bits, usando el [strtoull](https://en.cppreference.com/w/cpp/string/byte/strtoul) función.
--   Si no tiene éxito, como un número de 64 bits sin signo, [Sistema abierto.](https://en.cppreference.com/w/cpp/string/byte/strtol) función.
--   Si no tiene éxito, como un número de punto flotante [strtod](https://en.cppreference.com/w/cpp/string/byte/strtof) función.
--   De lo contrario, devuelve un error.
-
-El valor literal tiene el tipo más pequeño en el que se ajusta el valor.
-Por ejemplo, 1 se analiza como `UInt8` pero 256 se analiza como `UInt16`. Para obtener más información, consulte [Tipos de datos](../sql-reference/data-types/index.md).
-
-Ejemplos: `1`, `18446744073709551615`, `0xDEADBEEF`, `01`, `0.1`, `1e100`, `-1e-100`, `inf`, `nan`.
-
-### Cadena {#syntax-string-literal}
-
-Solo se admiten literales de cadena entre comillas simples. Los caracteres incluidos se pueden escapar de barra invertida. Las siguientes secuencias de escape tienen un valor especial correspondiente: `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\a`, `\v`, `\xHH`. En todos los demás casos, secuencias de escape en el formato `\c`, donde `c` cualquier carácter, se convierten a `c`. Significa que puedes usar las secuencias `\'`y`\\`. El valor tendrá el [Cadena](../sql-reference/data-types/string.md) tipo.
-
-En literales de cadena, necesitas escapar al menos `'` y `\`. Las comillas simples se pueden escapar con las comillas simples, literales `'It\'s'` y `'It''s'` son iguales.
-
-### Compuesto {#compound}
-
-Las matrices se construyen con corchetes `[1, 2, 3]`. Nuples están construidos con paréntesis `(1, 'Hello, world!', 2)`.
-Técnicamente, estos no son literales, sino expresiones con el operador de creación de matriz y el operador de creación de tuplas, respectivamente.
-Una matriz debe constar de al menos un elemento y una tupla debe tener al menos dos elementos.
-Hay un caso separado cuando aparecen tuplas en el `IN` cláusula de un `SELECT` consulta. Los resultados de la consulta pueden incluir tuplas, pero las tuplas no se pueden guardar en una base de datos (excepto las tablas con [Memoria](../engines/table-engines/special/memory.md) motor).
-
-### NULL {#null-literal}
-
-Indica que falta el valor.
-
-Para almacenar `NULL` en un campo de tabla, debe ser del [NULL](../sql-reference/data-types/nullable.md) tipo.
-
-Dependiendo del formato de datos (entrada o salida), `NULL` puede tener una representación diferente. Para obtener más información, consulte la documentación de [Formatos de datos](../interfaces/formats.md#formats).
-
-Hay muchos matices para el procesamiento `NULL`. Por ejemplo, si al menos uno de los argumentos de una operación de comparación es `NULL`, el resultado de esta operación también es `NULL`. Lo mismo es cierto para la multiplicación, la suma y otras operaciones. Para obtener más información, lea la documentación de cada operación.
-
-En las consultas, puede verificar `NULL` utilizando el [IS NULL](operators/index.md#operator-is-null) y [IS NOT NULL](operators/index.md) operadores y las funciones relacionadas `isNull` y `isNotNull`.
-
-## Función {#functions}
-
-Las llamadas a funciones se escriben como un identificador con una lista de argumentos (posiblemente vacíos) entre corchetes redondos. A diferencia de SQL estándar, los corchetes son necesarios, incluso para una lista de argumentos vacía. Ejemplo: `now()`.
-Hay funciones regulares y agregadas (ver la sección “Aggregate functions”). Algunas funciones agregadas pueden contener dos listas de argumentos entre paréntesis. Ejemplo: `quantile (0.9) (x)`. Estas funciones agregadas se llaman “parametric” funciones, y los argumentos en la primera lista se llaman “parameters”. La sintaxis de las funciones agregadas sin parámetros es la misma que para las funciones regulares.
-
-## Operador {#operators}
-
-Los operadores se convierten a sus funciones correspondientes durante el análisis de consultas, teniendo en cuenta su prioridad y asociatividad.
-Por ejemplo, la expresión `1 + 2 * 3 + 4` se transforma a `plus(plus(1, multiply(2, 3)), 4)`.
-
-## Tipos de datos y motores de tabla de base de datos {#data_types-and-database-table-engines}
-
-Tipos de datos y motores de tablas en el `CREATE` las consultas se escriben de la misma manera que los identificadores o funciones. En otras palabras, pueden o no contener una lista de argumentos entre corchetes. Para obtener más información, consulte las secciones “Data types,” “Table engines,” y “CREATE”.
-
-## Alias de expresión {#syntax-expression_aliases}
-
-Un alias es un nombre definido por el usuario para la expresión en una consulta.
-
-``` sql
-expr AS alias
-```
-
--   `AS` — The keyword for defining aliases. You can define the alias for a table name or a column name in a `SELECT` cláusula sin usar el `AS` palabra clave.
-
-        For example, `SELECT table_name_alias.column_name FROM table_name table_name_alias`.
-
-        In the [CAST](sql_reference/functions/type_conversion_functions.md#type_conversion_function-cast) function, the `AS` keyword has another meaning. See the description of the function.
-
--   `expr` — Any expression supported by ClickHouse.
-
-        For example, `SELECT column_name * 2 AS double FROM some_table`.
-
--   `alias` — Name for `expr`. Los alias deben cumplir con el [identificador](#syntax-identifiers) sintaxis.
-
-        For example, `SELECT "table t".column_name FROM table_name AS "table t"`.
-
-### Notas sobre el uso {#notes-on-usage}
-
-Los alias son globales para una consulta o subconsulta, y puede definir un alias en cualquier parte de una consulta para cualquier expresión. Por ejemplo, `SELECT (1 AS n) + 2, n`.
-
-Los alias no son visibles en subconsultas y entre subconsultas. Por ejemplo, al ejecutar la consulta `SELECT (SELECT sum(b.a) + num FROM b) - a.a AS num FROM a` ClickHouse genera la excepción `Unknown identifier: num`.
-
-Si se define un alias para las columnas de resultados `SELECT` cláusula de una subconsulta, estas columnas son visibles en la consulta externa. Por ejemplo, `SELECT n + m FROM (SELECT 1 AS n, 2 AS m)`.
-
-Tenga cuidado con los alias que son iguales a los nombres de columna o tabla. Consideremos el siguiente ejemplo:
-
-``` sql
-CREATE TABLE t
-(
-    a Int,
-    b Int
-)
-ENGINE = TinyLog()
-```
-
-``` sql
-SELECT
-    argMax(a, b),
-    sum(b) AS b
-FROM t
-```
-
-``` text
-Received exception from server (version 18.14.17):
-Code: 184. DB::Exception: Received from localhost:9000, 127.0.0.1. DB::Exception: Aggregate function sum(b) is found inside another aggregate function in query.
-```
-
-En este ejemplo, declaramos tabla `t` con columna `b`. Luego, al seleccionar los datos, definimos el `sum(b) AS b` apodo. Como los alias son globales, ClickHouse sustituyó el literal `b` en la expresión `argMax(a, b)` con la expresión `sum(b)`. Esta sustitución causó la excepción.
-
-## Asterisco {#asterisk}
-
-En un `SELECT` consulta, un asterisco puede reemplazar la expresión. Para obtener más información, consulte la sección “SELECT”.
-
-## Expresiones {#syntax-expressions}
-
-Una expresión es una función, identificador, literal, aplicación de un operador, expresión entre paréntesis, subconsulta o asterisco. También puede contener un alias.
-Una lista de expresiones es una o más expresiones separadas por comas.
-Las funciones y los operadores, a su vez, pueden tener expresiones como argumentos.

-# entrada {#input}
-
-`input(structure)` - función de tabla que permite convertir e insertar efectivamente los datos enviados al
-servidor con estructura dada a la tabla con otra estructura.
-
-`structure` - estructura de los datos enviados al servidor en el siguiente formato `'column1_name column1_type, column2_name column2_type, ...'`.
-Por ejemplo, `'id UInt32, name String'`.
-
-Esta función sólo se puede utilizar en `INSERT SELECT` consulta y sólo una vez, pero por lo demás se comporta como función de tabla ordinaria
-(por ejemplo, se puede usar en subconsulta, etc.).
-
-Los datos se pueden enviar de cualquier manera como para ordinario `INSERT` consulta y pasado en cualquier disponible [formato](../../interfaces/formats.md#formats)
-que debe especificarse al final de la consulta (a diferencia de lo ordinario `INSERT SELECT`).
-
-La característica principal de esta función es que cuando el servidor recibe datos del cliente, los convierte simultáneamente
-según la lista de expresiones en el `SELECT` cláusula e inserta en la tabla de destino. Tabla temporal
-con todos los datos transferidos no se crea.
-
-**Ejemplos**
-
--   Deje que el `test` tiene la siguiente estructura `(a String, b String)`
-    y datos en `data.csv` tiene una estructura diferente `(col1 String, col2 Date, col3 Int32)`. Consulta de inserción
-    datos de la `data.csv` en el `test` con conversión simultánea se ve así:
-
-<!-- -->
-
-``` bash
-$ cat data.csv | clickhouse-client --query="INSERT INTO test SELECT lower(col1), col3 * col3 FROM input('col1 String, col2 Date, col3 Int32') FORMAT CSV";
-```
-
--   Si `data.csv` contiene datos de la misma estructura `test_structure` como la mesa `test` entonces estas dos consultas son iguales:
-
-<!-- -->
-
-``` bash
-$ cat data.csv | clickhouse-client --query="INSERT INTO test FORMAT CSV"
-$ cat data.csv | clickhouse-client --query="INSERT INTO test SELECT * FROM input('test_structure') FORMAT CSV"
-```

-# mysql {#mysql}
-
-Permitir `SELECT` consultas que se realizarán en los datos que se almacenan en un servidor MySQL remoto.
-
-``` sql
-mysql('host:port', 'database', 'table', 'user', 'password'[, replace_query, 'on_duplicate_clause']);
-```
-
-**Parámetros**
-
--   `host:port` — MySQL server address.
-
--   `database` — Remote database name.
-
--   `table` — Remote table name.
-
--   `user` — MySQL user.
-
--   `password` — User password.
-
--   `replace_query` — Flag that converts `INSERT INTO` consultas a `REPLACE INTO`. Si `replace_query=1`, la consulta se reemplaza.
-
--   `on_duplicate_clause` — The `ON DUPLICATE KEY on_duplicate_clause` expresión que se añade a la `INSERT` consulta.
-
-        Example: `INSERT INTO t (c1,c2) VALUES ('a', 2) ON DUPLICATE KEY UPDATE c2 = c2 + 1`, where `on_duplicate_clause` is `UPDATE c2 = c2 + 1`. See the MySQL documentation to find which `on_duplicate_clause` you can use with the `ON DUPLICATE KEY` clause.
-
-        To specify `on_duplicate_clause` you need to pass `0` to the `replace_query` parameter. If you simultaneously pass `replace_query = 1` and `on_duplicate_clause`, ClickHouse generates an exception.
-
-Simple `WHERE` cláusulas tales como `=, !=, >, >=, <, <=` se ejecutan actualmente en el servidor MySQL.
-
-El resto de las condiciones y el `LIMIT` La restricción de muestreo se ejecuta en ClickHouse solo después de que finalice la consulta a MySQL.
-
-**Valor devuelto**
-
-Un objeto de tabla con las mismas columnas que la tabla MySQL original.

-Devuelve la tabla que está conectada a través de [ODBC](https://en.wikipedia.org/wiki/Open_Database_Connectivity).
-
-``` sql
-odbc(connection_settings, external_database, external_table)
-```
-
-Parámetros:
-
--   `connection_settings` — Name of the section with connection settings in the `odbc.ini` file.
--   `external_database` — Name of a database in an external DBMS.
--   `external_table` — Name of a table in the `external_database`.
-
-Para implementar con seguridad conexiones ODBC, ClickHouse usa un programa separado `clickhouse-odbc-bridge`. Si el controlador ODBC se carga directamente desde `clickhouse-server`, problemas de controlador pueden bloquear el servidor ClickHouse. ClickHouse se inicia automáticamente `clickhouse-odbc-bridge` cuando se requiere. El programa de puente ODBC se instala desde el mismo paquete que el `clickhouse-server`.
-
-Los campos con el `NULL` Los valores de la tabla externa se convierten en los valores predeterminados para el tipo de datos base. Por ejemplo, si un campo de tabla MySQL remoto tiene `INT NULL` tipo se convierte a 0 (el valor predeterminado para ClickHouse `Int32` tipo de datos).
-
-## Ejemplo de uso {#usage-example}
-
-**Obtener datos de la instalación local de MySQL a través de ODBC**
-
-Este ejemplo se comprueba para Ubuntu Linux 18.04 y el servidor MySQL 5.7.
-
-Asegúrese de que unixODBC y MySQL Connector están instalados.
-
-De forma predeterminada (si se instala desde paquetes), ClickHouse comienza como usuario `clickhouse`. Por lo tanto, debe crear y configurar este usuario en el servidor MySQL.
-
-``` bash
-$ sudo mysql
-```
-
-``` sql
-mysql> CREATE USER 'clickhouse'@'localhost' IDENTIFIED BY 'clickhouse';
-mysql> GRANT ALL PRIVILEGES ON *.* TO 'clickhouse'@'clickhouse' WITH GRANT OPTION;
-```
-
-A continuación, configure la conexión en `/etc/odbc.ini`.
-
-``` bash
-$ cat /etc/odbc.ini
-[mysqlconn]
-DRIVER = /usr/local/lib/libmyodbc5w.so
-SERVER = 127.0.0.1
-PORT = 3306
-DATABASE = test
-USERNAME = clickhouse
-PASSWORD = clickhouse
-```
-
-Puede verificar la conexión usando el `isql` utilidad desde la instalación de unixODBC.
-
-``` bash
-$ isql -v mysqlconn
-+-------------------------+
-| Connected!                            |

-
-# remoto, remoteSecure {#remote-remotesecure}
-
-Le permite acceder a servidores remotos sin crear un `Distributed` tabla.
-
-Firma:
-
-``` sql
-remote('addresses_expr', db, table[, 'user'[, 'password']])
-remote('addresses_expr', db.table[, 'user'[, 'password']])
-remoteSecure('addresses_expr', db, table[, 'user'[, 'password']])
-remoteSecure('addresses_expr', db.table[, 'user'[, 'password']])
-```
-
-`addresses_expr` – An expression that generates addresses of remote servers. This may be just one server address. The server address is `host:port` o simplemente `host`. El host se puede especificar como nombre de servidor o como dirección IPv4 o IPv6. Una dirección IPv6 se especifica entre corchetes. El puerto es el puerto TCP del servidor remoto. Si se omite el puerto, utiliza `tcp_port` del archivo de configuración del servidor (por defecto, 9000).
-
-!!! important "Importante"
-    El puerto es necesario para una dirección IPv6.
-
-Ejemplos:
-
-``` text
-example01-01-1
-example01-01-1:9000
-localhost
-127.0.0.1
-[::]:9000
-[2a02:6b8:0:1111::11]:9000
-```
-
-Se pueden separar varias direcciones por comas. En este caso, ClickHouse usará procesamiento distribuido, por lo que enviará la consulta a todas las direcciones especificadas (como a fragmentos con datos diferentes).
-
-Ejemplo:
-
-``` text
-example01-01-1,example01-02-1
-```
-
-Parte de la expresión se puede especificar entre llaves. El ejemplo anterior se puede escribir de la siguiente manera:
-
-``` text
-example01-0{1,2}-1
-```
-
-Los corchetes rizados pueden contener un rango de números separados por dos puntos (enteros no negativos). En este caso, el rango se expande a un conjunto de valores que generan direcciones de fragmentos. Si el primer número comienza con cero, los valores se forman con la misma alineación cero. El ejemplo anterior se puede escribir de la siguiente manera:
-
-``` text
-example01-{01..02}-1
-```
-
-Si tiene varios pares de llaves, genera el producto directo de los conjuntos correspondientes.
-
-Las direcciones y partes de las direcciones entre llaves se pueden separar mediante el símbolo de tubería (\|). En este caso, los conjuntos de direcciones correspondientes se interpretan como réplicas y la consulta se enviará a la primera réplica en buen estado. Sin embargo, las réplicas se iteran en el orden establecido actualmente en el [load_balancing](../../operations/settings/settings.md) configuración.
-
-Ejemplo:
-
-``` text
-example01-{01..02}-{1|2}
-```
-
-En este ejemplo se especifican dos fragmentos que tienen dos réplicas cada uno.
-
-El número de direcciones generadas está limitado por una constante. En este momento esto es 1000 direcciones.
-
-Uso de la `remote` función de la tabla es menos óptima que la creación de un `Distributed` mesa, porque en este caso, la conexión del servidor se restablece para cada solicitud. Además, si se establecen nombres de host, los nombres se resuelven y los errores no se cuentan cuando se trabaja con varias réplicas. Cuando procese un gran número de consultas, cree siempre el `Distributed` mesa antes de tiempo, y no utilice el `remote` función de la tabla.
-
-El `remote` puede ser útil en los siguientes casos:
-
--   Acceder a un servidor específico para la comparación de datos, la depuración y las pruebas.
--   Consultas entre varios clústeres de ClickHouse con fines de investigación.
--   Solicitudes distribuidas poco frecuentes que se realizan manualmente.
--   Solicitudes distribuidas donde el conjunto de servidores se redefine cada vez.
-
-Si el usuario no está especificado, `default` se utiliza.
-Si no se especifica la contraseña, se utiliza una contraseña vacía.
-
-`remoteSecure` - igual que `remote` but with secured connection. Default port — [Tcp_port_secure](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-tcp_port_secure) de config o 9440.

-toc_title: Vue d'ensemble de L'Architecture ClickHouse
----
-
-# Vue d'ensemble de L'Architecture ClickHouse {#overview-of-clickhouse-architecture}
-
-ClickHouse est un véritable SGBD orienté colonne. Les données sont stockées par colonnes et lors de l'exécution de tableaux (vecteurs ou morceaux de colonnes). Dans la mesure du possible, les opérations sont distribuées sur des tableaux, plutôt que sur des valeurs individuelles. Il est appelé “vectorized query execution,” et cela aide à réduire le coût du traitement des données réel.
-
-> Cette idée n'est pas nouvelle. Il remonte à la `APL` langage de programmation et ses descendants: `A +`, `J`, `K`, et `Q`. La programmation de tableau est utilisée dans le traitement des données scientifiques. Cette idée n'est pas non plus nouvelle dans les bases de données relationnelles: par exemple, elle est utilisée dans le `Vectorwise` système.
-
-Il existe deux approches différentes pour accélérer le traitement des requêtes: l'exécution vectorisée des requêtes et la génération de code d'exécution. Ce dernier supprime toute indirection et expédition dynamique. Aucune de ces approches est strictement meilleure que l'autre. La génération de code d'exécution peut être meilleure lorsqu'elle fusionne de nombreuses opérations, utilisant ainsi pleinement les unités D'exécution du processeur et le pipeline. L'exécution de requête vectorisée peut être moins pratique car elle implique des vecteurs temporaires qui doivent être écrits dans le cache et lus. Si les données temporaires ne rentre pas dans le cache L2, cela devient un problème. Mais l'exécution de requête vectorisée utilise plus facilement les capacités SIMD de la CPU. Un [document de recherche](http://15721.courses.cs.cmu.edu/spring2016/papers/p5-sompolski.pdf) écrit par nos amis montre qu'il est préférable de combiner les deux approches. ClickHouse utilise l'exécution de requête vectorisée et a un support initial limité pour la génération de code d'exécution.
-
-## Colonne {#columns}
-
-`IColumn` l'interface est utilisée pour représenter des colonnes en mémoire (en fait, des morceaux de colonnes). Cette interface fournit des méthodes d'aide pour la mise en œuvre de divers opérateurs relationnels. Presque toutes les opérations sont immuables: elles ne modifient pas la colonne d'origine, mais en créent une nouvelle modifiée. Par exemple, l' `IColumn :: filter` méthode accepte un masque d'octet de filtre. Il est utilisé pour le `WHERE` et `HAVING` opérateurs relationnels. Exemples supplémentaires: `IColumn :: permute` méthode de soutien `ORDER BY`, le `IColumn :: cut` méthode de soutien `LIMIT`.
-
-Divers `IColumn` application (`ColumnUInt8`, `ColumnString` et ainsi de suite) sont responsables de la mémoire disposition de colonnes. La disposition de la mémoire est généralement un tableau contigu. Pour le type entier de colonnes, c'est juste un contiguë tableau, comme `std :: vector`. Pour `String` et `Array` colonnes, il s'agit de deux vecteurs: Un pour tous les éléments du tableau, placé de manière contiguë, et un second pour les décalages au début de chaque tableau. Il y a aussi `ColumnConst` cela stocke une seule valeur en mémoire, mais ressemble à une colonne.
-
-## Champ {#field}
-
-Néanmoins, il est possible de travailler avec des valeurs individuelles ainsi. Pour représenter une valeur individuelle, la `Field` est utilisée. `Field` est juste une union discriminée de `UInt64`, `Int64`, `Float64`, `String` et `Array`. `IColumn` a l' `operator[]` méthode pour obtenir la n-ème valeur en tant que `Field` et la `insert` méthode pour ajouter un `Field` à la fin d'une colonne. Ces méthodes ne sont pas très efficaces, car ils nécessitent de traiter avec temporaire `Field` des objets représentant une valeur individuelle. Il existe des méthodes plus efficaces, telles que `insertFrom`, `insertRangeFrom` et ainsi de suite.
-
-`Field` ne pas avoir assez d'informations sur un type de données spécifique pour une table. Exemple, `UInt8`, `UInt16`, `UInt32`, et `UInt64` tous sont représentés comme `UInt64` dans un `Field`.
-
-## Abstractions Qui Fuient {#leaky-abstractions}
-
-`IColumn` a des méthodes pour les transformations relationnelles communes des données, mais elles ne répondent pas à tous les besoins. Exemple, `ColumnUInt64` ne pas avoir une méthode pour calculer la somme des deux colonnes, et `ColumnString` n'a pas de méthode pour exécuter une recherche de sous-chaîne. Ces innombrables routines sont mises en œuvre en dehors de `IColumn`.
-
-Diverses fonctions sur les colonnes peuvent être implémentées de manière générique et non efficace en utilisant `IColumn` méthodes pour extraire `Field` valeurs, ou d'une manière spécialisée en utilisant la connaissance de la disposition de la mémoire interne des données dans un `IColumn` application. Il est implémenté en lançant des fonctions à un `IColumn` tapez et traitez directement la représentation interne. Exemple, `ColumnUInt64` a l' `getData` méthode qui renvoie une référence à un tableau interne, puis une autre routine lit ou remplit ce tableau directement. Nous avons “leaky abstractions” permettent de spécialisations diverses routines.
-
-## Types De Données {#data_types}
-
-`IDataType` est responsable de la sérialisation et de la désérialisation: pour la lecture et l'écriture de morceaux de colonnes ou de valeurs individuelles sous forme binaire ou de texte. `IDataType` correspond directement aux types de données dans les tables. Par exemple, il y a `DataTypeUInt32`, `DataTypeDateTime`, `DataTypeString` et ainsi de suite.
-
-`IDataType` et `IColumn` ne sont que faiblement liés les uns aux autres. Différents types de données peuvent être représentés en mémoire par le même `IColumn` application. Exemple, `DataTypeUInt32` et `DataTypeDateTime` sont tous deux représentés par `ColumnUInt32` ou `ColumnConstUInt32`. En outre, le même type de données peut être représentée par différents `IColumn` application. Exemple, `DataTypeUInt8` peut être représenté par `ColumnUInt8` ou `ColumnConstUInt8`.
-
-`IDataType` stocke uniquement les métadonnées. Par exemple, `DataTypeUInt8` ne stocke rien du tout (sauf vptr) et `DataTypeFixedString` magasins juste `N` (la taille des chaînes de taille fixe).
-
-`IDataType` a des méthodes d'aide pour différents formats de données. Des exemples sont des méthodes pour sérialiser une valeur avec des guillemets possibles, pour sérialiser une valeur pour JSON et pour sérialiser une valeur dans le format XML. Il n'y a pas de correspondance directe avec les formats de données. Par exemple, les différents formats de données `Pretty` et `TabSeparated` pouvez utiliser le même `serializeTextEscaped` méthode d'aide à partir de la `IDataType` interface.
-
-## Bloc {#block}
-
-A `Block` est un conteneur qui représente un sous-ensemble (morceau) d'une table en mémoire. C'est juste un ensemble de triplets: `(IColumn, IDataType, column name)`. Pendant l'exécution de la requête, les données sont traitées par `Block`s. Si nous avons un `Block`, nous disposons de données (dans le `IColumn` objet), nous avons des informations sur son type (dans `IDataType`) qui nous indique comment traiter cette colonne, et nous avons le nom de la colonne. Il peut s'agir du nom de colonne d'origine de la table ou d'un nom artificiel attribué pour obtenir des résultats temporaires de calculs.
-
-Lorsque nous calculons une fonction sur des colonnes dans un bloc, nous ajoutons une autre colonne avec son résultat au bloc, et nous ne touchons pas les colonnes pour les arguments de la fonction car les opérations sont immuables. Plus tard, les colonnes inutiles peuvent être supprimées du bloc, mais pas modifiées. Il est pratique pour l'élimination des sous-expressions communes.
-
-Des blocs sont créés pour chaque bloc de données traité. Notez que pour le même type de calcul, les noms et les types de colonnes restent les mêmes pour différents blocs, et seules les données de colonne changent. Il est préférable de diviser les données de bloc de l'en-tête de bloc car les petites tailles de Bloc ont une surcharge élevée de chaînes temporaires pour copier shared_ptrs et les noms de colonnes.
-
-## Bloquer Les Flux {#block-streams}
-
-Les flux de blocs sont destinés au traitement des données. Nous utilisons des flux de blocs pour lire des données quelque part, effectuer des transformations de données ou écrire des données quelque part. `IBlockInputStream` a l' `read` méthode pour récupérer le bloc suivant, tandis que des. `IBlockOutputStream` a l' `write` méthode pour pousser le bloc quelque part.
-
-Les flux sont responsables de:
-
-1.  De la lecture ou de l'écriture dans une table. La table renvoie simplement un flux pour lire ou écrire des blocs.
-2.  Mise en œuvre des formats de données. Par exemple, si vous souhaitez envoyer des données vers un terminal `Pretty` format, vous créez un flux de sortie de bloc où vous poussez des blocs, et il les formate.
-3.  Effectuer des transformations de données. Disons que vous avez `IBlockInputStream` et veulent créer un flux filtré. Vous créez `FilterBlockInputStream` et l'initialiser avec votre flux de données. Puis quand vous tirez un bloc de `FilterBlockInputStream`, il extrait un bloc de votre flux, le filtre et vous renvoie le bloc filtré. Les pipelines d'exécution des requêtes sont représentés de cette façon.
-
-Il y a des transformations plus sophistiquées. Par exemple, lorsque vous tirez de `AggregatingBlockInputStream` il lit toutes les données à partir de sa source, agrégats, puis renvoie un flux de données agrégées pour vous. Un autre exemple: `UnionBlockInputStream` accepte de nombreuses sources d'entrée dans le constructeur et également un certain nombre de threads. Il lance plusieurs threads et lit à partir de plusieurs sources en parallèle.
-
-> Les flux de blocs utilisent le “pull” approche pour contrôler le flux: lorsque vous extrayez un bloc du premier flux, il extrait par conséquent les blocs requis des flux imbriqués, et l'ensemble du pipeline d'exécution fonctionnera. Ni “pull” ni “push” est la meilleure solution, car le flux de contrôle est implicite, ce qui limite l'implémentation de diverses fonctionnalités telles que l'exécution simultanée de plusieurs requêtes (fusion de plusieurs pipelines ensemble). Cette limitation pourrait être surmontée avec des coroutines ou simplement en exécutant des threads supplémentaires qui s'attendent les uns aux autres. Nous pouvons avoir plus de possibilités si nous rendons le flux de contrôle explicite: si nous localisons la logique pour passer des données d'une unité de calcul à une autre en dehors de ces unités de calcul. Lire ce [article](http://journal.stuffwithstuff.com/2013/01/13/iteration-inside-and-out/) pour plus de pensées.
-
-Il convient de noter que le pipeline d'exécution de la requête crée des données temporaires à chaque étape. Nous essayons de garder la taille du bloc suffisamment petite pour que les données temporaires tiennent dans le cache du processeur. Avec cette hypothèse, l'écriture et la lecture de données temporaires sont presque libres en comparaison avec d'autres calculs. Nous pourrions envisager une alternative, qui est de fusionner de nombreuses opérations dans le pipeline ensemble. Cela pourrait rendre le pipeline aussi court que possible et supprimer une grande partie des données temporaires, ce qui pourrait être un avantage, mais cela présente également des inconvénients. Par exemple, un pipeline divisé facilite l'implémentation de la mise en cache de données intermédiaires, le vol de données intermédiaires à partir de requêtes similaires exécutées en même temps et la fusion de pipelines pour des requêtes similaires.
-
-## Format {#formats}
-
-Les formats de données sont implémentés avec des flux de blocs. Il y a “presentational” formats appropriés uniquement pour la sortie de données vers le client, tels que `Pretty` format, qui fournit seulement `IBlockOutputStream`. Et il existe des formats d'entrée / sortie, tels que `TabSeparated` ou `JSONEachRow`.
-
-Il y a aussi des flux de lignes: `IRowInputStream` et `IRowOutputStream`. Ils vous permettent de tirer/pousser des données par des lignes individuelles, pas par des blocs. Et ils ne sont nécessaires que pour simplifier la mise en œuvre des formats orientés ligne. Wrapper `BlockInputStreamFromRowInputStream` et `BlockOutputStreamFromRowOutputStream` vous permet de convertir des flux orientés ligne en flux orientés blocs réguliers.
-
-## I/O {#io}
-
-Pour l'entrée/sortie orientée octet, il y a `ReadBuffer` et `WriteBuffer` les classes abstraites. Ils sont utilisés à la place de C++ `iostream`s. Ne vous inquiétez pas: chaque projet c++ mature utilise autre chose que `iostream`s pour de bonnes raisons.
-
-`ReadBuffer` et `WriteBuffer` sont juste un tampon contigu et un curseur pointant vers la position dans ce tampon. Les implémentations peuvent posséder ou non la mémoire du tampon. Il existe une méthode virtuelle pour remplir le tampon avec les données suivantes (pour `ReadBuffer`) ou pour vider le tampon quelque part (pour `WriteBuffer`). Les méthodes virtuelles sont rarement cités.
-
-Les implémentations de `ReadBuffer`/`WriteBuffer` sont utilisés pour travailler avec des fichiers et des descripteurs de fichiers et des sockets réseau, pour implémenter la compression (`CompressedWriteBuffer` is initialized with another WriteBuffer and performs compression before writing data to it), and for other purposes – the names `ConcatReadBuffer`, `LimitReadBuffer`, et `HashingWriteBuffer` parler pour eux-mêmes.
-
-Read / WriteBuffers ne traite que les octets. Il y a des fonctions de `ReadHelpers` et `WriteHelpers` fichiers d'en-tête pour aider à formater l'entrée / sortie. Par exemple, il existe des assistants pour écrire un nombre au format décimal.
-
-Regardons ce qui se passe lorsque vous voulez écrire un ensemble de résultats dans `JSON` format de sortie standard (stdout). Vous avez un jeu de résultats prêt à être récupéré `IBlockInputStream`. Vous créez `WriteBufferFromFileDescriptor(STDOUT_FILENO)` pour écrire des octets dans stdout. Vous créez `JSONRowOutputStream`, initialisé avec qui `WriteBuffer`, pour écrire des lignes dans `JSON` à stdout. Vous créez `BlockOutputStreamFromRowOutputStream` de plus, pour la représenter comme `IBlockOutputStream`. Ensuite, vous appelez `copyData` pour transférer des données de `IBlockInputStream` de `IBlockOutputStream` et tout fonctionne. Interne, `JSONRowOutputStream` écrira divers délimiteurs JSON et appellera `IDataType::serializeTextJSON` méthode avec une référence à `IColumn` et le numéro de ligne comme arguments. Conséquent, `IDataType::serializeTextJSON` appellera une méthode de `WriteHelpers.h`: exemple, `writeText` pour les types numériques et `writeJSONString` pour `DataTypeString`.
-
-## Table {#tables}
-
-Le `IStorage` l'interface représente les tables. Différentes implémentations de cette interface sont des moteurs de table différents. Les exemples sont `StorageMergeTree`, `StorageMemory` et ainsi de suite. Les Instances de ces classes ne sont que des tables.
-
-Clé `IStorage` les méthodes sont `read` et `write`. Il y a aussi des `alter`, `rename`, `drop` et ainsi de suite. Le `read` méthode accepte les arguments suivants: l'ensemble de colonnes à lire à partir d'un tableau, l' `AST` requête à considérer, et le nombre souhaité de flux de retour. Il renvoie un ou plusieurs `IBlockInputStream` objets et informations sur l'étape de traitement des données qui a été effectuée dans un moteur de table lors de l'exécution de la requête.
-
-Dans la plupart des cas, la méthode read n'est responsable que de la lecture des colonnes spécifiées à partir d'une table, et non d'un traitement ultérieur des données. Tout traitement ultérieur des données est effectué par l'interpréteur de requêtes et n'est pas de la responsabilité de `IStorage`.
-
-Mais il y a des exceptions notables:
-
--   La requête AST est transmise au `read` et le moteur de table peut l'utiliser pour dériver l'utilisation de l'index et pour lire moins de données à partir d'une table.
--   Parfois, le moteur de table peut traiter les données lui-même à une étape spécifique. Exemple, `StorageDistributed` peut envoyer une requête aux serveurs distants, leur demander de traiter les données à une étape où les données de différents serveurs distants peuvent être fusionnées, et renvoyer ces données prétraitées. L'interpréteur de requête termine ensuite le traitement des données.
-
-Table `read` la méthode peut retourner plusieurs `IBlockInputStream` objets permettant le traitement parallèle des données. Ces flux d'entrée de bloc multiples peuvent lire à partir d'une table en parallèle. Ensuite, vous pouvez envelopper ces flux avec diverses transformations (telles que l'évaluation d'expression ou le filtrage) qui peuvent être calculées indépendamment et créer un `UnionBlockInputStream` en plus d'eux, pour lire à partir de plusieurs flux en parallèle.
-
-Il y a aussi des `TableFunction`s. Ce sont des fonctions qui renvoient un `IStorage` objet à utiliser dans le `FROM` la clause d'une requête.
-
-Pour avoir une idée rapide de la façon d'implémenter votre moteur de table, regardez quelque chose de simple, comme `StorageMemory` ou `StorageTinyLog`.
-
-> Comme le résultat de l' `read` méthode, `IStorage` retourner `QueryProcessingStage` – information about what parts of the query were already calculated inside storage.
-
-## Analyseur {#parsers}
-
-Un analyseur de descente récursif écrit à la main analyse une requête. Exemple, `ParserSelectQuery` appelle simplement récursivement les analyseurs sous-jacents pour diverses parties de la requête. Les analyseurs créent un `AST`. Le `AST` est représenté par des nœuds, qui sont des instances de `IAST`.
-
-> Les générateurs d'analyseurs ne sont pas utilisés pour des raisons historiques.
-
-## Interprète {#interpreters}
-
-Les interprètes sont responsables de la création du pipeline d'exécution des requêtes à partir `AST`. Il existe des interprètes simples, tels que `InterpreterExistsQuery` et `InterpreterDropQuery` ou le plus sophistiqué de `InterpreterSelectQuery`. Le pipeline d'exécution de requête est une combinaison de flux d'entrée ou de sortie de bloc. Par exemple, le résultat de l'interprétation de la `SELECT` la requête est la `IBlockInputStream` pour lire le jeu de résultats; le résultat de la requête d'INSERTION est l' `IBlockOutputStream` pour écrire des données à insérer, et le résultat de l'interprétation `INSERT SELECT` la requête est la `IBlockInputStream` cela renvoie un jeu de résultats vide lors de la première lecture, mais qui copie `SELECT` de `INSERT` dans le même temps.
-
-`InterpreterSelectQuery` utiliser `ExpressionAnalyzer` et `ExpressionActions` machines pour l'analyse des requêtes et des transformations. C'est là que la plupart des optimisations de requêtes basées sur des règles sont effectuées. `ExpressionAnalyzer` est assez désordonné et devrait être réécrit: diverses transformations et optimisations de requête doivent être extraites dans des classes séparées pour permettre des transformations modulaires ou une requête.
-
-## Fonction {#functions}
-
-Il y a des fonctions ordinaires et des fonctions agrégées. Pour les fonctions d'agrégation, voir la section suivante.
-
-Ordinary functions don't change the number of rows – they work as if they are processing each row independently. In fact, functions are not called for individual rows, but for `Block`'s de données pour implémenter l'exécution de requête vectorisée.
-
-Il y a quelques fonctions diverses, comme [la taille de bloc](../sql-reference/functions/other-functions.md#function-blocksize), [rowNumberInBlock](../sql-reference/functions/other-functions.md#function-rownumberinblock), et [runningAccumulate](../sql-reference/functions/other-functions.md#function-runningaccumulate), qui exploitent le traitement de bloc et violent l'indépendance des lignes.
-
-ClickHouse a un typage fort, donc il n'y a pas de conversion de type implicite. Si une fonction ne prend pas en charge une combinaison spécifique de types, elle lève une exception. Mais les fonctions peuvent fonctionner (être surchargées) pour de nombreuses combinaisons de types différentes. Par exemple, l' `plus` fonction (pour mettre en œuvre la `+` opérateur) fonctionne pour toute combinaison de types numériques: `UInt8` + `Float32`, `UInt16` + `Int8` et ainsi de suite. En outre, certaines fonctions variadiques peuvent accepter n'importe quel nombre d'arguments, tels que `concat` fonction.
-
-L'implémentation d'une fonction peut être légèrement gênante car une fonction distribue explicitement les types de données pris en charge et pris en charge `IColumns`. Par exemple, l' `plus` la fonction a du code généré par l'instanciation D'un modèle C++ pour chaque combinaison de types numériques, et des arguments gauche et droit constants ou non constants.
-
-C'est un excellent endroit pour implémenter la génération de code d'exécution pour éviter le gonflement du code de modèle. En outre, il permet d'ajouter des fonctions fusionnées comme Fusionné Multiplier-Ajouter ou de faire plusieurs comparaisons dans une itération de boucle.
-
-En raison de l'exécution de requête vectorisée, les fonctions ne sont pas court-circuitées. Par exemple, si vous écrivez `WHERE f(x) AND g(y)` les deux faces sont calculés, même pour les lignes, quand `f(x)` est égal à zéro (sauf quand `f(x)` est une expression constante nulle). Mais si la sélectivité de l' `f(x)` la condition est élevée, et le calcul de `f(x)` est beaucoup moins cher que `g(y)`, il est préférable d'implémenter le calcul multi-pass. Il serait d'abord calculer `f(x)` puis filtrer les colonnes par la suite, puis de calculer `g(y)` uniquement pour les petits morceaux de données filtrés.
-
-## Les Fonctions D'Agrégation {#aggregate-functions}
-
-Les fonctions d'agrégation sont des fonctions avec État. Ils accumulent les valeurs passées dans certains etats et vous permettent d'obtenir des résultats de cet état. Ils sont gérés avec le `IAggregateFunction` interface. Les États peuvent être assez simples (l'État pour `AggregateFunctionCount` est juste un seul `UInt64` valeur) ou très complexes (l'état de `AggregateFunctionUniqCombined` est une combinaison linéaire du tableau, d'une table de hachage, et un `HyperLogLog` structure probabiliste des données).
-
-Les États sont répartis en `Arena` (un pool de mémoire) pour traiter plusieurs états lors de l'exécution d'une cardinalité élevée `GROUP BY` requête. Les États peuvent avoir un constructeur et un destructeur non triviaux: par exemple, les États d'agrégation compliqués peuvent allouer eux-mêmes de la mémoire supplémentaire. Il faut accorder une certaine attention à la création et à la destruction des États et à la transmission appropriée de leur propriété et de leur ordre de destruction.
-
-Les États d'agrégation peuvent être sérialisés et désérialisés pour passer sur le réseau pendant l'exécution de la requête distribuée ou pour les écrire sur le disque où il n'y a pas assez de RAM. Ils peuvent même être stockés dans une table avec le `DataTypeAggregateFunction` pour permettre l'agrégation incrémentielle des données.
-
-> Le format de données sérialisé pour les états de fonction d'agrégat n'est pas versionné pour le moment. C'est ok si les États d'agrégat ne sont stockés que temporairement. Mais nous avons l' `AggregatingMergeTree` moteur de table pour l'agrégation incrémentielle, et les gens l'utilisent déjà en production. C'est la raison pour laquelle la rétrocompatibilité est requise lors de la modification du format sérialisé pour toute fonction d'agrégat à l'avenir.
-
-## Serveur {#server}
-
-Le serveur implémente plusieurs interfaces différentes:
-
--   Une interface HTTP pour tous les clients étrangers.
--   Une interface TCP pour le client clickhouse natif et pour la communication inter-serveur lors de l'exécution de la requête distribuée.
--   Une interface pour transférer des données pour la réplication.
-
-En interne, il s'agit simplement d'un serveur multithread primitif sans coroutines ni fibres. Étant donné que le serveur n'est pas conçu pour traiter un taux élevé de requêtes simples, mais pour traiter un taux relativement faible de requêtes complexes, chacun d'eux peut traiter une grande quantité de données à des fins d'analyse.
-
-Le serveur initialise le `Context` classe avec l'environnement nécessaire à l'exécution des requêtes: la liste des bases de données disponibles, des utilisateurs et des droits d'accès, des paramètres, des clusters, la liste des processus, le journal des requêtes, etc. Les interprètes utilisent cet environnement.
-
-Nous maintenons une compatibilité ascendante et descendante complète pour le protocole TCP du serveur: les anciens clients peuvent parler à de nouveaux serveurs, et les nouveaux clients peuvent parler à d'anciens serveurs. Mais nous ne voulons pas le maintenir éternellement, et nous supprimons le support pour les anciennes versions après environ un an.
-
-!!! note "Note"
-    Pour la plupart des applications externes, nous vous recommandons d'utiliser L'interface HTTP car elle est simple et facile à utiliser. Le protocole TCP est plus étroitement lié aux structures de données internes: il utilise un format interne pour passer des blocs de données, et il utilise un cadrage personnalisé pour les données compressées. Nous n'avons pas publié de bibliothèque C pour ce protocole car elle nécessite de lier la plupart de la base de code ClickHouse, ce qui n'est pas pratique.
-
-## Exécution De Requête Distribuée {#distributed-query-execution}
-
-Les serveurs d'une configuration de cluster sont pour la plupart indépendants. Vous pouvez créer un `Distributed` table sur un ou tous les serveurs dans un cluster. Le `Distributed` table does not store data itself – it only provides a “view” à toutes les tables sur plusieurs nœuds d'un cluster. Lorsque vous sélectionnez à partir d'un `Distributed` table, il réécrit cette requête, choisit les nœuds distants en fonction des paramètres d'équilibrage de charge et leur envoie la requête. Le `Distributed` table demande aux serveurs distants de traiter une requête jusqu'à une étape où les résultats intermédiaires de différents serveurs peuvent être fusionnés. Puis il reçoit les résultats intermédiaires et les fusionne. La table distribuée essaie de distribuer autant de travail que possible aux serveurs distants et n'envoie pas beaucoup de données intermédiaires sur le réseau.
-
-Les choses deviennent plus compliquées lorsque vous avez des sous-requêtes dans des clauses IN ou JOIN, et que chacune d'elles utilise un `Distributed` table. Nous avons différentes stratégies pour l'exécution de ces requêtes.
-
-Il n'existe pas de plan de requête global pour l'exécution des requêtes distribuées. Chaque nœud a son plan de requête local pour sa partie du travail. Nous n'avons qu'une simple exécution de requête distribuée en une seule passe: nous envoyons des requêtes pour les nœuds distants, puis fusionnons les résultats. Mais cela n'est pas possible pour les requêtes compliquées avec des groupes de cardinalité élevés ou avec une grande quantité de données temporaires pour la jointure. Dans de tels cas, nous avons besoin de “reshuffle” données entre les serveurs, ce qui nécessite une coordination supplémentaire. ClickHouse ne supporte pas ce type d'exécution de requête, et nous devons y travailler.
-
-## Fusion De L'Arbre {#merge-tree}
-
-`MergeTree` est une famille de moteurs de stockage qui prend en charge l'indexation par clé primaire. La clé primaire peut être un tuple arbitraire de colonnes ou d'expressions. De données dans un `MergeTree` la table est stockée dans “parts”. Chaque partie stocke les données dans l'ordre de la clé primaire, de sorte que les données sont ordonnées lexicographiquement par le tuple de clé primaire. Toutes les colonnes du tableau sont stockés dans différents `column.bin` les fichiers dans ces régions. Les fichiers sont constitués de blocs compressés. Chaque bloc est généralement de 64 KO à 1 Mo de données non compressées, en fonction de la taille de la valeur moyenne. Les blocs sont constitués de valeurs de colonne placées de manière contiguë l'une après l'autre. Les valeurs de colonne sont dans le même ordre pour chaque colonne (la clé primaire définit l'ordre), donc lorsque vous itérez par plusieurs colonnes, vous obtenez des valeurs pour les lignes correspondantes.
-
-La clé primaire elle-même est “sparse”. Il ne traite pas chaque ligne, mais seulement certaines plages de données. Séparé `primary.idx` fichier a la valeur de la clé primaire pour chaque N-ième ligne, où N est appelé `index_granularity` (habituellement, N = 8192). Aussi, pour chaque colonne, nous avons `column.mrk` les fichiers avec l' “marks,” qui sont des décalages à chaque N-ème ligne dans le fichier de données. Chaque marque est une paire: le décalage dans le fichier au début du bloc compressé, et le décalage dans le bloc décompressé au début des données. Habituellement, les blocs compressés sont alignés par des marques, et le décalage dans le bloc décompressé est nul. Les données pour `primary.idx` réside toujours dans la mémoire, et les données pour `column.mrk` les fichiers sont mis en cache.
-
-Quand nous allons lire quelque chose d'une partie dans `MergeTree` nous regardons `primary.idx` données et locate plages qui pourraient contenir des données demandées, puis regardez `column.mrk` données et calculer des décalages pour savoir où commencer à lire ces plages. En raison de la rareté, les données excédentaires peuvent être lues. ClickHouse ne convient pas à une charge élevée de requêtes ponctuelles simples, car toute la gamme avec `index_granularity` les lignes doivent être lues pour chaque clé, et le bloc compressé entier doit être décompressé pour chaque colonne. Nous avons rendu l'index clairsemé parce que nous devons être en mesure de maintenir des milliards de lignes par serveur unique sans consommation de mémoire notable pour l'index. De plus, comme la clé primaire est clairsemée, elle n'est pas unique: elle ne peut pas vérifier l'existence de la clé dans la table au moment de l'insertion. Vous pourriez avoir plusieurs lignes avec la même clé dans une table.
-
-Lorsque vous `INSERT` un tas de données dans `MergeTree`, ce groupe est trié par ordre de clé primaire et forme une nouvelle partie. Il existe des threads d'arrière-plan qui sélectionnent périodiquement certaines parties et les fusionnent en une seule partie triée pour maintenir le nombre de parties relativement faible. C'est pourquoi il est appelé `MergeTree`. Bien sûr, la fusion conduit à “write amplification”. Toutes les parties sont immuables: elles sont seulement créées et supprimées, mais pas modifiées. Lorsque SELECT est exécuté, il contient un instantané de la table (un ensemble de parties). Après la Fusion, nous conservons également les anciennes pièces pendant un certain temps pour faciliter une récupération après une défaillance, donc si nous voyons qu'une partie fusionnée est probablement cassée, nous pouvons la remplacer par ses parties sources.
-
-`MergeTree` n'est pas un arbre LSM car il ne contient pas “memtable” et “log”: inserted data is written directly to the filesystem. This makes it suitable only to INSERT data in batches, not by individual row and not very frequently – about once per second is ok, but a thousand times a second is not. We did it this way for simplicity's sake, and because we are already inserting data in batches in our applications.
-
-> Les tables MergeTree ne peuvent avoir qu'un seul index (primaire): il n'y a pas d'index secondaires. Il serait bon d'autoriser plusieurs représentations physiques sous une table logique, par exemple, pour stocker des données dans plus d'un ordre physique ou même pour autoriser des représentations avec des données pré-agrégées avec des données originales.
-
-Il existe des moteurs MergeTree qui effectuent un travail supplémentaire lors des fusions en arrière-plan. Les exemples sont `CollapsingMergeTree` et `AggregatingMergeTree`. Cela pourrait être traité comme un support spécial pour les mises à jour. Gardez à l'esprit que ce ne sont pas de vraies mises à jour car les utilisateurs n'ont généralement aucun contrôle sur le moment où les fusions en arrière-plan sont exécutées et les données dans un `MergeTree` la table est presque toujours stockée dans plus d'une partie, pas sous une forme complètement fusionnée.
-
-## Réplication {#replication}
-
-La réplication dans ClickHouse peut être configurée sur une base par table. Vous pouvez avoir des tables répliquées et des tables non répliquées sur le même serveur. Vous pouvez également avoir des tables répliquées de différentes manières, comme une table avec une réplication à deux facteurs et une autre avec trois facteurs.
-
-La réplication est implémentée dans le `ReplicatedMergeTree` moteur de stockage. Le chemin d'accès dans `ZooKeeper` est spécifié comme paramètre pour le moteur de stockage. Toutes les tables avec le même chemin dans `ZooKeeper` devenez des répliques les unes des autres: elles synchronisent leurs données et maintiennent la cohérence. Les répliques peuvent être ajoutées et supprimées dynamiquement simplement en créant ou en supprimant une table.
-
-La réplication utilise un schéma multi-maître asynchrone. Vous pouvez insérer des données dans n'importe quel réplica qui a une session avec `ZooKeeper`, et les données sont répliquées à toutes les autres répliques de manière asynchrone. Parce que ClickHouse ne prend pas en charge les mises à jour, la réplication est sans conflit. Comme il n'y a pas d'accusé de réception de quorum des insertions, les données juste insérées peuvent être perdues si un nœud échoue.
-
-Les métadonnées pour la réplication sont stockées dans ZooKeeper. Il existe un journal de réplication qui répertorie les actions à effectuer. Les Actions sont: obtenir une partie; fusionner des parties; déposer une partition, et ainsi de suite. Chaque réplica copie le journal de réplication dans sa file d'attente, puis exécute les actions de la file d'attente. Par exemple, sur l'insertion, l' “get the part” l'action est créée dans le journal, et chaque réplique téléchargements de la partie. Les fusions sont coordonnées entre les répliques pour obtenir des résultats identiques aux octets. Toutes les parties sont fusionnées de la même manière sur toutes les répliques. Il est réalisé en élisant une réplique en tant que leader, et cette réplique initie fusionne et écrit “merge parts” actions dans le journal.
-
-La réplication est physique: seules les parties compressées sont transférées entre les nœuds, pas les requêtes. Les fusions sont traitées sur chaque réplique indépendamment dans la plupart des cas pour réduire les coûts du réseau en évitant l'amplification du réseau. Grand fusionné les pièces sont envoyées sur le réseau uniquement en cas de retard de réplication.
-
-En outre, chaque réplique stocke son état dans ZooKeeper comme l'ensemble des pièces et ses sommes de contrôle. Lorsque l'état sur le système de fichiers local diverge de l'état de référence dans ZooKeeper, le réplica restaure sa cohérence en téléchargeant les parties manquantes et brisées à partir d'autres réplicas. Lorsqu'il y a des données inattendues ou brisées dans le système de fichiers local, ClickHouse ne les supprime pas, mais les déplace dans un répertoire séparé et les oublie.
-
-!!! note "Note"
-    Le cluster ClickHouse est constitué de fragments indépendants, et chaque fragment est constitué de répliques. Le cluster est **pas élastique**, donc, après avoir ajouté un nouveau fragment, les données ne sont pas rééquilibrées automatiquement entre les fragments. Au lieu de cela, la charge du cluster est censée être ajustée pour être inégale. Cette implémentation vous donne plus de contrôle, et c'est ok pour des clusters relativement petits, tels que des dizaines de nœuds. Mais pour les clusters avec des centaines de nœuds que nous utilisons en production, cette approche devient un inconvénient important. Nous devrions implémenter un moteur de table qui s'étend sur le cluster avec des régions répliquées dynamiquement qui pourraient être divisées et équilibrées automatiquement entre les clusters.

-Cela va créer de l' `programs/clickhouse` exécutable, qui peut être utilisé avec `client` ou `server` argument.
-
-# Comment Construire ClickHouse sur N'importe quel Linux {#how-to-build-clickhouse-on-any-linux}
-
-La construction nécessite les composants suivants:
-
--   Git (est utilisé uniquement pour extraire les sources, ce n'est pas nécessaire pour la construction)
--   CMake 3.10 ou plus récent
--   Ninja (recommandé) ou faire
--   Compilateur C++: gcc 10 ou clang 8 ou plus récent
--   Linker: lld ou gold (le classique GNU LD ne fonctionnera pas)
--   Python (est seulement utilisé dans la construction LLVM et il est facultatif)
-
-Si tous les composants sont installés, vous pouvez construire de la même manière que les étapes ci-dessus.
-
-Exemple pour Ubuntu Eoan:
-
-    sudo apt update
-    sudo apt install git cmake ninja-build g++ python
-    git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-    mkdir build && cd build
-    cmake ../ClickHouse
-    ninja
-
-Exemple Pour openSUSE Tumbleweed:
-
-    sudo zypper install git cmake ninja gcc-c++ python lld
-    git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-    mkdir build && cd build
-    cmake ../ClickHouse
-    ninja
-
-Exemple Pour Fedora Rawhide:
-
-    sudo yum update
-    yum --nogpg install git cmake make gcc-c++ python3
-    git clone --recursive https://github.com/ClickHouse/ClickHouse.git
-    mkdir build && cd build
-    cmake ../ClickHouse
-    make -j $(nproc)
-
-# Vous N'avez pas à construire ClickHouse {#you-dont-have-to-build-clickhouse}
-
-ClickHouse est disponible dans des binaires et des paquets pré-construits. Les binaires sont portables et peuvent être exécutés sur N'importe quelle saveur Linux.
-
-Ils sont conçus pour les versions stables, préconfigurables et de test aussi longtemps que pour chaque commit à master et pour chaque requête d'extraction.
-
-Pour trouver la construction la plus fraîche de `master`, aller à [page commits](https://github.com/ClickHouse/ClickHouse/commits/master), cliquez sur la première coche verte ou Croix Rouge près de commit, et cliquez sur le “Details” lien à droite après “ClickHouse Build Check”.

-toc_title: "Le D\xE9butant Clickhouse Developer Instruction"
----
-
-La construction de ClickHouse est prise en charge sous Linux, FreeBSD et Mac OS X.
-
-# Si Vous Utilisez Windows {#if-you-use-windows}
-
-Si vous utilisez Windows, vous devez créer une machine virtuelle avec Ubuntu. Pour commencer à travailler avec une machine virtuelle, installez VirtualBox. Vous pouvez télécharger Ubuntu sur le site: https://www.ubuntu.com/#download. veuillez créer une machine virtuelle à partir de l'image téléchargée (vous devez réserver au moins 4 Go de RAM pour cela). Pour exécuter un terminal de ligne de commande dans Ubuntu, recherchez un programme contenant le mot “terminal” dans son nom (gnome-terminal, konsole etc.) ou appuyez simplement sur Ctrl + Alt + T.
-
-# Si vous utilisez un système 32 bits {#if-you-use-a-32-bit-system}
-
-ClickHouse ne peut pas fonctionner ou construire sur un système 32 bits. Vous devez acquérir l'accès à un système 64 bits et vous pouvez continuer la lecture.
-
-# Création d'un référentiel sur GitHub {#creating-a-repository-on-github}
-
-Pour commencer à travailler avec clickhouse repository, vous aurez besoin d'un compte GitHub.
-
-Vous en avez probablement déjà un, mais si vous ne le faites pas, veuillez vous inscrire à https://github.com. dans le cas où vous n'avez pas de clés SSH, vous devez les générer, puis les télécharger sur GitHub. Il est nécessaire pour l'envoi de vos correctifs. Il est également possible d'utiliser les mêmes clés SSH que vous utilisez avec d'autres serveurs SSH - vous les avez probablement déjà.
-
-Créer un fork de clickhouse repository. Pour ce faire, cliquez sur l' “fork” bouton dans le coin supérieur droit à https://github.com/ClickHouse/ClickHouse. il fourche votre propre copie de ClickHouse / ClickHouse à votre compte.
-
-Le processus de développement consiste d'abord à valider les modifications prévues dans votre fork de ClickHouse, puis à créer un “pull request” pour que ces modifications soient acceptées dans le référentiel principal (ClickHouse/ClickHouse).
-
-Pour travailler avec les dépôts git, veuillez installer `git`.
-
-Pour ce faire dans Ubuntu vous exécutez dans le terminal de ligne de commande:
-
-    sudo apt update
-    sudo apt install git
-
-Un bref manuel sur l'utilisation de Git peut être trouvé ici: https://education.github.com/git-cheat-sheet-education.pdf.
-Pour un manuel détaillé sur Git voir https://git-scm.com/book/en/v2.
-
-# Clonage D'un référentiel sur votre machine de développement {#cloning-a-repository-to-your-development-machine}
-
-Ensuite, vous devez télécharger les fichiers source sur votre machine de travail. Ceci est appelé “to clone a repository” parce qu'il crée une copie locale du dépôt sur votre machine de travail.
-
-Dans le terminal de ligne de commande exécuter:
-
-    git clone --recursive git@github.com:your_github_username/ClickHouse.git
-    cd ClickHouse
-
-Remarque: Veuillez remplacer *your_github_username* avec ce qui est approprié!
-
-Cette commande va créer un répertoire `ClickHouse` contenant la copie de travail du projet.
-
-Il est important que le chemin d'accès au répertoire de travail ne contienne aucun espace, car cela peut entraîner des problèmes lors de l'exécution du système de construction.
-
-Veuillez noter que clickhouse repository utilise `submodules`. That is what the references to additional repositories are called (i.e. external libraries on which the project depends). It means that when cloning the repository you need to specify the `--recursive` drapeau comme dans l'exemple ci-dessus. Si le dépôt a été cloné sans submodules, pour télécharger, vous devez exécuter les opérations suivantes:
-
-    git submodule init
-    git submodule update
-
-Vous pouvez vérifier l'état avec la commande: `git submodule status`.
-
-Si vous obtenez le message d'erreur suivantes:
-
-    Permission denied (publickey).
-    fatal: Could not read from remote repository.
-
-    Please make sure you have the correct access rights
-    and the repository exists.
-
-Cela signifie généralement que les clés SSH pour la connexion à GitHub sont manquantes. Ces clés sont normalement situés dans `~/.ssh`. Pour que les clés SSH soient acceptées, vous devez les télécharger dans la section Paramètres de L'interface utilisateur GitHub.
-
-Vous pouvez également cloner le référentiel via le protocole https:
-
-    git clone https://github.com/ClickHouse/ClickHouse.git
-
-Ceci, cependant, ne vous permettra pas d'envoyer vos modifications sur le serveur. Vous pouvez toujours l'utiliser temporairement et ajouter les clés SSH plus tard en remplaçant l'adresse distante du référentiel par `git remote` commande.
-
-Vous pouvez également ajouter l'adresse du dépôt clickhouse original à votre référentiel local pour extraire les mises à jour à partir de là:
-
-    git remote add upstream git@github.com:ClickHouse/ClickHouse.git
-
-Après avoir exécuté avec succès cette commande vous serez en mesure de tirer les mises à jour du repo clickhouse principal en exécutant `git pull upstream master`.
-
-## Travailler avec des Submodules {#working-with-submodules}
-
-Travailler avec des sous-modules dans git pourrait être douloureux. Prochaines commandes aidera à gérer:
-
-    # ! each command accepts --recursive
-    # Update remote URLs for submodules. Barely rare case
-    git submodule sync
-    # Add new submodules
-    git submodule init
-    # Update existing submodules to the current state
-    git submodule update
-    # Two last commands could be merged together
-    git submodule update --init
-
-Les commandes suivantes vous aideront à réinitialiser tous les sous-modules à l'état initial (!AVERTISSEMENT! - tout changement à l'intérieur sera supprimé):
-
-    # Synchronizes submodules' remote URL with .gitmodules
-    git submodule sync --recursive
-    # Update the registered submodules with initialize not yet initialized
-    git submodule update --init --recursive
-    # Reset all changes done after HEAD
-    git submodule foreach git reset --hard
-    # Clean files from .gitignore
-    git submodule foreach git clean -xfd
-    # Repeat last 4 commands for all submodule
-    git submodule foreach git submodule sync --recursive
-    git submodule foreach git submodule update --init --recursive
-    git submodule foreach git submodule foreach git reset --hard
-    git submodule foreach git submodule foreach git clean -xfd
-
-# Système De Construction {#build-system}
-
-ClickHouse utilise CMake et Ninja pour la construction.
-
-CMake - un système de méta-construction qui peut générer des fichiers Ninja (tâches de construction).
-Ninja - un système de construction plus petit avec un accent sur la vitesse utilisée pour exécuter ces tâches générées cmake.
-
-Pour installer sur Ubuntu, Debian ou mint run `sudo apt install cmake ninja-build`.
-
-Sur CentOS, RedHat run `sudo yum install cmake ninja-build`.
-
-Si vous utilisez Arch ou Gentoo, vous savez probablement vous - même comment installer CMake.
-
-Pour installer CMake et Ninja sur Mac OS X installez D'abord Homebrew puis installez tout le reste via brew:
-
-    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-    brew install cmake ninja
-
-Ensuite, vérifiez la version de CMake: `cmake --version`. Si elle est inférieure à 3.3, vous devez installer une version plus récente du site web: https://cmake.org/download/.
-
-# Bibliothèques Externes Facultatives {#optional-external-libraries}
-
-ClickHouse utilise plusieurs bibliothèques externes pour la construction. Tous n'ont pas besoin d'être installés séparément car ils sont construits avec ClickHouse à partir des sources situées dans les sous-modules. Vous pouvez vérifier la liste dans `contrib`.
-
-# Compilateur C++  {#c-compiler}
-
-Les compilateurs GCC à partir de la version 10 et Clang version 8 ou supérieure sont pris en charge pour construire ClickHouse.
-
-Les builds officiels de Yandex utilisent actuellement GCC car ils génèrent du code machine de performances légèrement meilleures (ce qui donne une différence allant jusqu'à plusieurs pour cent selon nos benchmarks). Et Clang est plus pratique pour le développement habituellement. Cependant, notre plate-forme d'intégration continue (CI) vérifie environ une douzaine de combinaisons de construction.
-
-Pour installer GCC sur Ubuntu Exécutez: `sudo apt install gcc g++`
-
-Vérifiez la version de gcc: `gcc --version`. Si elle est inférieure à 10, suivez les instructions ici: https://clickhouse.tech/docs/fr/development/build/#install-gcc-10.
-
-Mac OS X build est pris en charge uniquement pour Clang. Il suffit d'exécuter `brew install llvm`
-
-Si vous décidez d'utiliser Clang, vous pouvez également installer `libc++` et `lld` si vous savez ce que c'est. Utiliser `ccache` est également recommandé.
-
-# Le Processus De Construction {#the-building-process}
-
-Maintenant que vous êtes prêt à construire ClickHouse nous vous conseillons de créer un répertoire séparé `build` à l'intérieur de `ClickHouse` qui contiendra tous les artefacts de construction:
-
-    mkdir build
-    cd build
-
-Vous pouvez avoir plusieurs répertoires différents (build_release, build_debug, etc.) pour les différents types de construction.
-
-Tandis qu'à l'intérieur de la `build` répertoire, configurez votre build en exécutant CMake. Avant la première exécution, vous devez définir des variables d'environnement qui spécifient le compilateur (compilateur gcc version 10 dans cet exemple).
-
-Linux:
-
-    export CC=gcc-10 CXX=g++-10
-    cmake ..
-
-Mac OS X:
-
-    export CC=clang CXX=clang++
-    cmake ..
-
-Le `CC` variable spécifie le compilateur pour C (abréviation de compilateur C), et `CXX` variable indique quel compilateur C++ doit être utilisé pour la construction.
-
-Pour une version plus rapide, vous pouvez recourir à l' `debug` build type - Une construction sans optimisations. Pour cela fournissez le paramètre suivant `-D CMAKE_BUILD_TYPE=Debug`:
-
-    cmake -D CMAKE_BUILD_TYPE=Debug ..
-
-Vous pouvez modifier le type de génération en exécutant cette commande dans le `build` répertoire.
-
-Exécutez ninja pour construire:
-
-    ninja clickhouse-server clickhouse-client
-
-Seules les binaires vont être construites dans cet exemple.
-
-Si vous avez besoin de construire tous les binaires (utilitaires et tests), vous devez exécuter ninja sans paramètres:
-
-    ninja
-
-La construction complète nécessite environ 30 Go d'espace disque libre ou 15 Go pour construire les binaires principaux.
-
-Lorsqu'une grande quantité de RAM est disponible sur la machine de construction vous devez limiter le nombre de tâches de construction exécutées en parallèle avec `-j` param:
-
-    ninja -j 1 clickhouse-server clickhouse-client
-
-Sur les machines avec 4 Go de RAM, il est recommandé de spécifier 1, pour 8 Go de RAM `-j 2` est recommandé.
-
-Si vous recevez le message: `ninja: error: loading 'build.ninja': No such file or directory`, cela signifie que la génération d'une configuration de construction a échoué et que vous devez inspecter le message ci-dessus.
-
-Après le démarrage réussi du processus de construction, vous verrez la progression de la construction - le nombre de tâches traitées et le nombre total de tâches.
-
-Lors de la construction de messages sur les fichiers protobuf dans la bibliothèque libhdfs2 comme `libprotobuf WARNING` peuvent apparaître. Ils touchent rien et sont sûrs d'être ignoré.
-
-Lors de la construction, vous obtenez un fichier exécutable `ClickHouse/<build_dir>/programs/clickhouse`:
-
-    ls -l programs/clickhouse
-
-# Exécution de L'exécutable construit de ClickHouse {#running-the-built-executable-of-clickhouse}
-
-Pour exécuter le serveur sous l'utilisateur actuel vous devez naviguer vers `ClickHouse/programs/server/` (situé à l'extérieur de `build` et les exécuter:
-
-    ../../build/programs/clickhouse server
-
-Dans ce cas, ClickHouse utilisera les fichiers de configuration situés dans le répertoire courant. Vous pouvez l'exécuter `clickhouse server` depuis n'importe quel répertoire spécifiant le chemin d'accès à un fichier de configuration en tant que paramètre de ligne de commande `--config-file`.
-
-Pour vous connecter à ClickHouse avec clickhouse-client dans un autre terminal, accédez à `ClickHouse/build/programs/` et exécuter `./clickhouse client`.
-
-Si vous obtenez `Connection refused` message sur Mac OS X ou FreeBSD, essayez de spécifier l'adresse hôte 127.0.0.1:
-
-    clickhouse client --host 127.0.0.1
-
-Vous pouvez remplacer la version de production de clickhouse binary installée dans votre système par votre clickhouse Binary sur mesure. Pour ce faire, installez ClickHouse sur votre machine en suivant les instructions du site officiel. Ensuite, exécutez ce qui suit:
-
-    sudo service clickhouse-server stop
-    sudo cp ClickHouse/build/programs/clickhouse /usr/bin/
-    sudo service clickhouse-server start
-
-Notez que `clickhouse-client`, `clickhouse-server` et d'autres sont des liens symboliques à la commune `clickhouse` binaire.
-
-Vous pouvez également exécuter votre binaire ClickHouse personnalisé avec le fichier de configuration du package clickhouse installé sur votre système:
-
-    sudo service clickhouse-server stop
-    sudo -u clickhouse ClickHouse/build/programs/clickhouse server --config-file /etc/clickhouse-server/config.xml
-
-# IDE (environnement de développement intégré) {#ide-integrated-development-environment}
-
-Si vous ne savez pas quel IDE utiliser, nous vous recommandons D'utiliser CLion. CLion est un logiciel commercial, mais il offre une période d'essai gratuite de 30 jours. Il est également gratuit pour les étudiants. CLion peut être utilisé à la fois sur Linux et sur Mac OS X.
-
-KDevelop et QTCreator sont d'autres grandes alternatives D'un IDE pour développer ClickHouse. KDevelop est un IDE très pratique bien qu'instable. Si KDevelop se bloque après un certain temps lors de l'ouverture du projet, vous devez cliquer sur “Stop All” bouton dès qu'il a ouvert la liste des fichiers du projet. Après cela, KDevelop devrait être bien pour travailler avec.
-
-En tant qu'éditeurs de code simples, vous pouvez utiliser Sublime Text ou Visual Studio Code, ou Kate (qui sont tous disponibles sur Linux).
-
-Juste au cas où, il convient de mentionner que CLion crée `build` chemin sur son propre, il aussi sur son propre sélectionne `debug` pour le type de construction, pour la configuration, il utilise une version de CMake définie dans CLion et non celle installée par vous, et enfin, CLion utilisera `make` pour exécuter construire des tâches au lieu de `ninja`. C'est un comportement normal, gardez cela à l'esprit pour éviter toute confusion.

-# Des Données De Test {#test-data}
-
-Le développement de ClickHouse nécessite souvent le chargement d'ensembles de données réalistes. Il est particulièrement important pour les tests de performance. Nous avons un ensemble spécialement préparé de données anonymisées de Yandex.Metrica. Il nécessite en outre quelques 3 Go d'espace disque libre. Notez que ces données ne sont pas requises pour accomplir la plupart des tâches de développement.

-# La Création De Pull Request {#creating-pull-request}
-
-Accédez à votre référentiel fork dans L'interface utilisateur de GitHub. Si vous avez développé dans une branche, vous devez sélectionner cette branche. Il y aura un “Pull request” bouton situé sur l'écran. En substance, cela signifie “create a request for accepting my changes into the main repository”.
-
-Une demande d'extraction peuvent être créés, même si le travail n'est pas encore terminée. Dans ce cas veuillez mettre le mot “WIP” (travaux en cours) au début du titre, il peut être modifié plus tard. Ceci est utile pour l'examen coopératif et la discussion des changements ainsi que pour l'exécution de tous les tests disponibles. Il est important que vous fournissiez une brève description de vos modifications, il sera ensuite utilisé pour générer des journaux de modifications de version.
-
-Les tests commenceront dès que les employés de Yandex étiqueteront votre PR avec une étiquette “can be tested”. The results of some first checks (e.g. code style) will come in within several minutes. Build check results will arrive within half an hour. And the main set of tests will report itself within an hour.
-
-Le système préparera les builds binaires ClickHouse pour votre demande de tirage individuellement. Pour récupérer ces versions cliquez sur le “Details” lien à côté “ClickHouse build check” entrée dans la liste de vérifications. Vous y trouverez des liens directs vers les construit .paquets deb de ClickHouse que vous pouvez déployer même sur vos serveurs de production (si vous n'avez pas peur).
-
-Très probablement, certaines des constructions échoueront à la première fois. Cela est dû au fait que nous avons vérifier s'appuie à la fois avec gcc, ainsi qu'avec clang, pratiquement tous les avertissements existants (toujours avec le `-Werror` drapeau) activé pour clang. Sur cette même page, vous pouvez trouver tous les journaux de construction afin que vous n'ayez pas à construire ClickHouse de toutes les manières possibles.

-# Comment écrire du Code C++  {#how-to-write-c-code}
-
-## Recommandations Générales {#general-recommendations}
-
-**1.** Ce qui suit sont des recommandations, pas des exigences.
-
-**2.** Si vous modifiez du code, il est logique de suivre le formatage du code existant.
-
-**3.** Le style de Code est nécessaire pour la cohérence. La cohérence facilite la lecture du code et facilite également la recherche du code.
-
-**4.** Beaucoup de règles n'ont pas de raisons logiques; elles sont dictées par des pratiques établies.
-
-## Formater {#formatting}
-
-**1.** La plupart du formatage se fera automatiquement par `clang-format`.
-
-**2.** Les tirets sont 4 espaces. Configurez votre environnement de développement afin qu'un onglet ajoute quatre espaces.
-
-**3.** Les crochets d'ouverture et de fermeture doivent être sur une ligne séparée.
-
-``` cpp
-inline void readBoolText(bool & x, ReadBuffer & buf)
-{
-    char tmp = '0';
-    readChar(tmp, buf);
-    x = tmp != '0';
-}
-```
-
-**4.** Si le corps entier de la fonction est un `statement` il peut donc être placé sur une seule ligne. Place des espaces autour des accolades (en plus de l'espace à la fin de la ligne).
-
-``` cpp
-inline size_t mask() const                { return buf_size() - 1; }
-inline size_t place(HashValue x) const    { return x & mask(); }
-```
-
-**5.** Pour les fonctions. Ne mettez pas d'espaces entre parenthèses.
-
-``` cpp
-void reinsert(const Value & x)
-```
-
-``` cpp
-memcpy(&buf[place_value], &x, sizeof(x));
-```
-
-**6.** Dans `if`, `for`, `while` et d'autres expressions, un espace est inséré devant le support d'ouverture (par opposition aux appels de fonction).
-
-``` cpp
-for (size_t i = 0; i < rows; i += storage.index_granularity)
-```
-
-**7.** Ajouter des espaces autour des opérateurs binaires (`+`, `-`, `*`, `/`, `%`, …) and the ternary operator `?:`.
-
-``` cpp
-UInt16 year = (s[0] - '0') * 1000 + (s[1] - '0') * 100 + (s[2] - '0') * 10 + (s[3] - '0');
-UInt8 month = (s[5] - '0') * 10 + (s[6] - '0');
-UInt8 day = (s[8] - '0') * 10 + (s[9] - '0');
-```
-
-**8.** Si un saut de ligne est entré, placez l'opérateur sur une nouvelle ligne et augmentez le retrait avant.
-
-``` cpp
-if (elapsed_ns)
-    message << " ("
-        << rows_read_on_server * 1000000000 / elapsed_ns << " rows/s., "
-        << bytes_read_on_server * 1000.0 / elapsed_ns << " MB/s.) ";
-```
-
-**9.** Vous pouvez utiliser des espaces pour l'alignement dans une ligne, si vous le souhaitez.
-
-``` cpp
-dst.ClickLogID         = click.LogID;
-dst.ClickEventID       = click.EventID;
-dst.ClickGoodEvent     = click.GoodEvent;
-```
-
-**10.** N'utilisez pas d'espaces autour des opérateurs `.`, `->`.
-
-Si nécessaire, l'opérateur peut être renvoyé à la ligne suivante. Dans ce cas, le décalage devant celui-ci est augmenté.
-
-**11.** N'utilisez pas d'espace pour séparer les opérateurs unaires (`--`, `++`, `*`, `&`, …) from the argument.
-
-**12.** Mettre un espace après une virgule, mais pas avant. La même règle vaut pour un point-virgule à l'intérieur d'un `for` expression.
-
-**13.** Ne pas utiliser des espaces pour séparer les `[]` opérateur.
-
-**14.** Dans un `template <...>` expression, utiliser un espace entre les `template` et `<`; pas d'espace après `<` ou avant `>`.
-
-``` cpp
-template <typename TKey, typename TValue>
-struct AggregatedStatElement
-{}
-```
-
-**15.** Dans les classes et les structures, écrivez `public`, `private`, et `protected` sur le même niveau que `class/struct` et tiret le reste du code.
-
-``` cpp
-template <typename T>
-class MultiVersion
-{
-public:
-    /// Version of object for usage. shared_ptr manage lifetime of version.
-    using Version = std::shared_ptr<const T>;
-    ...
-}
-```
-
-**16.** Si le même `namespace` est utilisé pour l'ensemble du fichier, et il n'y a rien d'autre significatif, un décalage n'est pas nécessaire à l'intérieur `namespace`.
-
-**17.** Si le bloc pour un `if`, `for`, `while` ou autres expressions se compose d'un seul `statement`, les accolades sont facultatives. Place de la `statement` sur une ligne séparée, à la place. Cette règle est également valable pour les imbriqués `if`, `for`, `while`, …
-
-Mais si l'intérieur `statement` contient des accolades ou `else` le bloc externe doit être écrit dans les accolades.
-
-``` cpp
-/// Finish write.
-for (auto & stream : streams)
-    stream.second->finalize();
-```
-
-**18.** Il ne devrait pas y avoir d'espaces aux extrémités des lignes.
-
-**19.** Les fichiers Source sont encodés en UTF-8.
-
-**20.** Les caractères non-ASCII peuvent être utilisés dans les littéraux de chaîne.
-
-``` cpp
-<< ", " << (timer.elapsed() / chunks_stats.hits) << " μsec/hit.";
-```
-
-**21.** N'écrivez pas plusieurs expressions sur une seule ligne.
-
-**22.** Groupez les sections de code à l'intérieur des fonctions et séparez-les avec pas plus d'une ligne vide.
-
-**23.** Séparez les fonctions, les classes, etc. avec une ou deux lignes vides.
-
-**24.** `A const` (liés à une valeur) doit être écrit avant le nom du type.
-
-``` cpp
-//correct
-const char * pos
-const std::string & s
-//incorrect
-char const * pos
-```
-
-**25.** Lors de la déclaration d'un pointeur ou d'une référence, le `*` et `&` les symboles doivent être séparés par des espaces des deux côtés.
-
-``` cpp
-//correct
-const char * pos
-//incorrect
-const char* pos
-const char *pos
-```
-
-**26.** Lors de l'utilisation de types de modèles, les alias avec le `using` mot-clé (sauf dans les cas les plus simples).
-
-En d'autres termes, les paramètres du modèle sont indiquées que dans `using` et ne sont pas répétés dans le code.
-
-`using` peut être déclaré localement, comme dans une fonction.
-
-``` cpp
-//correct
-using FileStreams = std::map<std::string, std::shared_ptr<Stream>>;
-FileStreams streams;
-//incorrect
-std::map<std::string, std::shared_ptr<Stream>> streams;
-```
-
-**27.** Ne déclarez pas plusieurs variables de types différents dans une instruction.
-
-``` cpp
-//incorrect
-int x, *y;
-```
-
-**28.** N'utilisez pas de moulages de style C.
-
-``` cpp
-//incorrect
-std::cerr << (int)c <<; std::endl;
-//correct
-std::cerr << static_cast<int>(c) << std::endl;
-```
-
-**29.** Dans les classes et les structures, groupez les membres et les fonctions séparément dans chaque portée de visibilité.
-
-**30.** Pour les petites classes et structures, il n'est pas nécessaire de séparer la déclaration de méthode de l'implémentation.
-
-La même chose est vraie pour les petites méthodes dans toutes les classes ou structures.
-
-Pour les classes et les structures modélisées, ne séparez pas les déclarations de méthode de l'implémentation (car sinon elles doivent être définies dans la même unité de traduction).
-
-**31.** Vous pouvez envelopper des lignes à 140 caractères, au lieu de 80.
-
-**32.** Utilisez toujours les opérateurs d'incrémentation/décrémentation de préfixe si postfix n'est pas requis.
-
-``` cpp
-for (Names::const_iterator it = column_names.begin(); it != column_names.end(); ++it)
-```
-
-## Commentaire {#comments}
-
-**1.** Assurez-vous d'ajouter des commentaires pour toutes les parties non triviales du code.
-
-C'est très important. Écrit le commentaire peut vous aider à réaliser que le code n'est pas nécessaire, ou qu'il est mal conçu.
-
-``` cpp
-/** Part of piece of memory, that can be used.
-  * For example, if internal_buffer is 1MB, and there was only 10 bytes loaded to buffer from file for reading,
-  * then working_buffer will have size of only 10 bytes
-  * (working_buffer.end() will point to position right after those 10 bytes available for read).
-  */
-```
-
-**2.** Les commentaires peuvent être aussi détaillées que nécessaire.
-
-**3.** Placez les commentaires avant le code qu'ils décrivent. Dans de rares cas, des commentaires peuvent venir après le code, sur la même ligne.
-
-``` cpp
-/** Parses and executes the query.
-*/
-void executeQuery(
-    ReadBuffer & istr, /// Where to read the query from (and data for INSERT, if applicable)
-    WriteBuffer & ostr, /// Where to write the result
-    Context & context, /// DB, tables, data types, engines, functions, aggregate functions...
-    BlockInputStreamPtr & query_plan, /// Here could be written the description on how query was executed
-    QueryProcessingStage::Enum stage = QueryProcessingStage::Complete /// Up to which stage process the SELECT query
-    )
-```
-
-**4.** Les commentaires doivent être rédigés en anglais seulement.
-
-**5.** Si vous écrivez une bibliothèque, incluez des commentaires détaillés l'expliquant dans le fichier d'en-tête principal.
-
-**6.** N'ajoutez pas de commentaires qui ne fournissent pas d'informations supplémentaires. En particulier, ne laissez pas de commentaires vides comme celui-ci:
-
-``` cpp
-/*
-* Procedure Name:
-* Original procedure name:
-* Author:
-* Date of creation:
-* Dates of modification:
-* Modification authors:
-* Original file name:
-* Purpose:
-* Intent:
-* Designation:
-* Classes used:
-* Constants:
-* Local variables:
-* Parameters:
-* Date of creation:
-* Purpose:
-*/
-```
-
-L'exemple est emprunté à partir de la ressource http://home.tamk.fi/~jaalto/cours/coding-style/doc/désuète-code/.
-
-**7.** Ne pas écrire des commentaires de déchets (auteur, date de création .. au début de chaque fichier.
-
-**8.** Les commentaires sur une seule ligne commencent par trois barres obliques: `///` et les commentaires multi-lignes commencer avec `/**`. Ces commentaires sont pris en considération “documentation”.
-
-REMARQUE: Vous pouvez utiliser Doxygen pour générer de la documentation à partir de ces commentaires. Mais Doxygen n'est généralement pas utilisé car il est plus pratique de naviguer dans le code dans L'IDE.
-
-**9.** Les commentaires multilignes ne doivent pas avoir de lignes vides au début et à la fin (sauf la ligne qui ferme un commentaire multilignes).
-
-**10.** Pour commenter le code, utilisez des commentaires de base, pas “documenting” commentaire.
-
-**11.** Supprimez les parties commentées du code avant de valider.
-
-**12.** N'utilisez pas de blasphème dans les commentaires ou le code.
-
-**13.** N'utilisez pas de majuscules. N'utilisez pas de ponctuation excessive.
-
-``` cpp
-/// WHAT THE FAIL???
-```
-
-**14.** N'utilisez pas de commentaires pour créer des délimiteurs.
-
-``` cpp
-///******************************************************
-```
-
-**15.** Ne commencez pas les discussions dans les commentaires.
-
-``` cpp
-/// Why did you do this stuff?
-```
-
-**16.** Il n'est pas nécessaire d'écrire un commentaire à la fin d'un bloc décrivant de quoi il s'agissait.
-
-``` cpp
-/// for
-```

-**1.** Utilisez des lettres minuscules avec des traits de soulignement dans les noms des variables et des membres de la classe.
-
-``` cpp
-size_t max_block_size;
-```
-
-**2.** Pour les noms de fonctions (méthodes), utilisez camelCase commençant par une lettre minuscule.
-
-``` cpp
-std::string getName() const override { return "Memory"; }
-```
-
-**3.** Pour les noms de classes (structures), utilisez CamelCase commençant par une lettre majuscule. Les préfixes autres que I ne sont pas utilisés pour les interfaces.
-
-``` cpp
-class StorageMemory : public IStorage
-```
-
-**4.** `using` sont nommées de la même manière que les classes, ou avec `_t` sur la fin.
-
-**5.** Noms des arguments de type de modèle: dans les cas simples, utilisez `T`; `T`, `U`; `T1`, `T2`.
-
-Pour les cas plus complexes, suivez les règles pour les noms de classe ou ajoutez le préfixe `T`.
-
-``` cpp
-template <typename TKey, typename TValue>
-struct AggregatedStatElement
-```
-
-**6.** Noms des arguments constants du modèle: suivez les règles pour les noms de variables ou utilisez `N` dans les cas simples.
-
-``` cpp
-template <bool without_www>
-struct ExtractDomain
-```
-
-**7.** Pour les classes abstraites (interfaces), vous pouvez ajouter `I` préfixe.
-
-``` cpp
-class IBlockInputStream
-```
-
-**8.** Si vous utilisez une variable localement, vous pouvez utiliser le nom court.
-
-Dans tous les autres cas, utilisez un nom qui décrit la signification.
-
-``` cpp
-bool info_successfully_loaded = false;
-```
-
-**9.** Les noms de `define`les constantes s et globales utilisent ALL_CAPS avec des traits de soulignement.
-
-``` cpp
-#define MAX_SRC_TABLE_NAMES_TO_STORE 1000
-```
-
-**10.** Les noms de fichiers doivent utiliser le même style que leur contenu.
-
-Si un fichier contient une seule classe, nommez-le de la même manière que la classe (CamelCase).
-
-Si le fichier contient une seule fonction, nommez le fichier de la même manière que la fonction (camelCase).
-
-**11.** Si le nom contient une abréviation, puis:
-
--   Pour les noms de variables, l'abréviation doit utiliser des lettres minuscules `mysql_connection` (pas `mySQL_connection`).
--   Pour les noms de classes et de fonctions, conservez les majuscules dans l'abréviation`MySQLConnection` (pas `MySqlConnection`).
-
-**12.** Les arguments du constructeur utilisés uniquement pour initialiser les membres de la classe doivent être nommés de la même manière que les membres de la classe, mais avec un trait de soulignement à la fin.
-
-``` cpp
-FileQueueProcessor(
-    const std::string & path_,
-    const std::string & prefix_,
-    std::shared_ptr<FileHandler> handler_)
-    : path(path_),
-    prefix(prefix_),
-    handler(handler_),
-    log(&Logger::get("FileQueueProcessor"))
-{
-}
-```
-
-Le suffixe de soulignement peut être omis si l'argument n'est pas utilisé dans le corps du constructeur.
-
-**13.** Il n'y a pas de différence dans les noms des variables locales et des membres de classe (aucun préfixe requis).
-
-``` cpp
-timer (not m_timer)
-```
-
-**14.** Pour les constantes dans un `enum`, utilisez CamelCase avec une lettre majuscule. ALL_CAPS est également acceptable. Si l' `enum` est non local, utilisez un `enum class`.
-
-``` cpp
-enum class CompressionMethod
-{
-    QuickLZ = 0,
-    LZ4     = 1,
-};
-```
-
-**15.** Tous les noms doivent être en anglais. La translittération des mots russes n'est pas autorisé.
-
-    not Stroka
-
-**16.** Les abréviations sont acceptables si elles sont bien connues (quand vous pouvez facilement trouver la signification de l'abréviation dans Wikipédia ou dans un moteur de recherche).
-
-    `AST`, `SQL`.
-
-    Not `NVDH` (some random letters)
-
-Les mots incomplets sont acceptables si la version abrégée est d'usage courant.
-
-Vous pouvez également utiliser une abréviation si le nom complet est ensuite incluse dans les commentaires.
-
-**17.** Les noms de fichiers avec le code source C++ doivent avoir `.cpp` extension. Fichiers d'en-tête doit avoir la `.h` extension.
-
-## Comment écrire du Code {#how-to-write-code}
-
-**1.** Gestion de la mémoire.
-
-Désallocation manuelle de la mémoire (`delete`) ne peut être utilisé que dans le code de la bibliothèque.
-
-Dans le code de la bibliothèque, de la `delete` l'opérateur ne peut être utilisé dans des destructeurs.
-
-Dans le code de l'application, la mémoire doit être libérée par l'objet qui la possède.
-
-Exemple:
-
--   Le plus simple est de placer un objet sur la pile, ou d'en faire un membre d'une autre classe.
--   Pour un grand nombre de petits objets, utiliser des récipients.
--   Pour la désallocation automatique d'un petit nombre d'objets qui résident dans le tas, utilisez `shared_ptr/unique_ptr`.
-
-**2.** La gestion des ressources.
-
-Utiliser `RAII` et voir ci-dessus.
-
-**3.** La gestion des erreurs.
-
-Utilisez des exceptions. Dans la plupart des cas, vous avez seulement besoin de lancer une exception, et n'avez pas besoin de l'attraper (à cause de `RAII`).
-
-Dans les applications de traitement de données hors ligne, il est souvent acceptable de ne pas attraper d'exceptions.
-
-Dans les serveurs qui gèrent les demandes des utilisateurs, il suffit généralement d'attraper des exceptions au niveau supérieur du gestionnaire de connexion.
-
-Dans les fonctions de thread, vous devez attraper et conserver toutes les exceptions pour les repasser dans le thread principal après `join`.
-
-``` cpp
-/// If there weren't any calculations yet, calculate the first block synchronously
-if (!started)
-{
-    calculate();
-    started = true;
-}
-else /// If calculations are already in progress, wait for the result
-    pool.wait();
-
-if (exception)
-    exception->rethrow();
-```
-
-Ne cachez jamais les exceptions sans les manipuler. Ne mettez jamais aveuglément toutes les exceptions au journal.
-
-``` cpp
-//Not correct
-catch (...) {}
-```
-
-Si vous devez ignorer certaines exceptions, ne le faites que pour des exceptions spécifiques et repensez le reste.
-
-``` cpp
-catch (const DB::Exception & e)
-{
-    if (e.code() == ErrorCodes::UNKNOWN_AGGREGATE_FUNCTION)
-        return nullptr;
-    else
-        throw;
-}
-```
-
-Lorsque vous utilisez des fonctions avec des codes de réponse ou `errno` toujours vérifier le résultat et de lever une exception en cas d'erreur.
-
-``` cpp
-if (0 != close(fd))
-    throwFromErrno("Cannot close file " + file_name, ErrorCodes::CANNOT_CLOSE_FILE);
-```
-
-`Do not use assert`.
-
-**4.** Les types d'Exception.
-
-Il n'est pas nécessaire d'utiliser une hiérarchie d'exceptions complexe dans le code de l'application. Le texte d'exception doit être compréhensible pour un administrateur système.
-
-**5.** Lancer des exceptions de destructeurs.
-
-Ce n'est pas recommandé, mais il est permis.
-
-Utilisez les options suivantes:
-
--   Créer une fonction (`done()` ou `finalize()`) qui vont faire tout le travail en amont qui pourrait conduire à une exception. Si cette fonction a été appelée, il ne devrait y avoir aucune exception dans le destructeur plus tard.
--   Les tâches trop complexes (comme l'envoi de messages sur le réseau) peuvent être placées dans une méthode distincte que l'utilisateur de la classe devra appeler avant la destruction.
--   Si il y a une exception dans le destructeur, il est préférable de l'enregistrer que de le cacher (si l'enregistreur est disponible).
--   Dans les applications simples, il est acceptable de compter sur `std::terminate` (pour les cas de `noexcept` par défaut en C++11) pour gérer les exceptions.
-
-**6.** Blocs de code anonymes.
-
-Vous pouvez créer un bloc de code séparé à l'intérieur d'une seule fonction afin de rendre certaines variables locales, de sorte que les destructeurs sont appelés à la sortie du bloc.
-
-``` cpp
-Block block = data.in->read();
-
-{
-    std::lock_guard<std::mutex> lock(mutex);
-    data.ready = true;
-    data.block = block;
-}
-
-ready_any.set();
-```
-
-**7.** Multithreading.
-
-Dans les programmes de traitement de données hors ligne:
-
--   Essayez d'obtenir les meilleures performances possibles sur un seul noyau CPU. Vous pouvez ensuite paralléliser votre code si nécessaire.
-
-Dans les applications serveur:
-
--   Utiliser le pool de threads pour traiter les demandes. À ce stade, nous n'avons pas eu de tâches nécessitant un changement de contexte dans l'espace utilisateur.
-
-La fourche n'est pas utilisé pour la parallélisation.
-
-**8.** Synchronisation des threads.
-
-Souvent, il est possible de faire en sorte que différents threads utilisent différentes cellules de mémoire (encore mieux: différentes lignes de cache,) et de ne pas utiliser de synchronisation de thread (sauf `joinAll`).
-
-Si la synchronisation est nécessaire, dans la plupart des cas, il suffit d'utiliser mutex sous `lock_guard`.
-
-Dans d'autres cas, utilisez des primitives de synchronisation système. Ne pas utiliser occupé attendre.
-
-Les opérations atomiques ne doivent être utilisées que dans les cas les plus simples.
-
-N'essayez pas d'implémenter des structures de données sans verrou à moins qu'il ne s'agisse de votre principal domaine d'expertise.
-
-**9.** Pointeurs vs références.
-
-Dans la plupart des cas, préférez les références.
-
-**10.** const.
-
-Utiliser des références constantes, des pointeurs vers des constantes, `const_iterator` et const méthodes.
-
-Considérer `const` pour être par défaut et utiliser non-`const` seulement quand c'est nécessaire.
-
-Lors du passage de variables par valeur, en utilisant `const` habituellement ne fait pas de sens.
-
-**11.** non signé.
-
-Utiliser `unsigned` si nécessaire.
-
-**12.** Les types numériques.
-
-Utiliser les types `UInt8`, `UInt16`, `UInt32`, `UInt64`, `Int8`, `Int16`, `Int32`, et `Int64` ainsi que `size_t`, `ssize_t`, et `ptrdiff_t`.
-
-N'utilisez pas ces types pour les nombres: `signed/unsigned long`, `long long`, `short`, `signed/unsigned char`, `char`.
-
-**13.** Passer des arguments.
-
-Passer des valeurs complexes par référence (y compris `std::string`).
-
-Si une fonction capture la propriété d'un objet créé dans le tas, définissez le type d'argument `shared_ptr` ou `unique_ptr`.
-
-**14.** Les valeurs de retour.
-
-Dans la plupart des cas, il suffit d'utiliser `return`. Ne pas écrire `return std::move(res)`.
-
-Si la fonction alloue un objet sur le tas et le renvoie, utilisez `shared_ptr` ou `unique_ptr`.
-
-Dans de rares cas, vous devrez peut-être renvoyer la valeur via un argument. Dans ce cas, l'argument doit être une référence.
-
-``` cpp
-using AggregateFunctionPtr = std::shared_ptr<IAggregateFunction>;
-
-/** Allows creating an aggregate function by its name.
-  */
-class AggregateFunctionFactory
-{
-public:
-    AggregateFunctionFactory();
-    AggregateFunctionPtr get(const String & name, const DataTypes & argument_types) const;
-```
-
-**15.** espace de noms.
-
-Il n'est pas nécessaire d'utiliser une `namespace` pour le code de l'application.
-
-Les petites bibliothèques n'ont pas besoin de cela non plus.
-
-Pour les bibliothèques moyennes et grandes, mettez tout dans un `namespace`.
-
-Dans la bibliothèque `.h` fichier, vous pouvez utiliser `namespace detail` pour masquer les détails d'implémentation non nécessaires pour le code de l'application.
-
-Dans un `.cpp` fichier, vous pouvez utiliser un `static` ou un espace de noms anonyme pour masquer les symboles.
-
-Aussi, un `namespace` peut être utilisé pour un `enum` pour éviter que les noms correspondants ne tombent dans un `namespace` (mais il est préférable d'utiliser un `enum class`).
-
-**16.** Initialisation différée.
-
-Si des arguments sont requis pour l'initialisation, vous ne devriez normalement pas écrire de constructeur par défaut.
-
-Si plus tard, vous devez retarder l'initialisation, vous pouvez ajouter un constructeur par défaut qui créera un objet invalide. Ou, pour un petit nombre d'objets, vous pouvez utiliser `shared_ptr/unique_ptr`.
-
-``` cpp
-Loader(DB::Connection * connection_, const std::string & query, size_t max_block_size_);
-
-/// For deferred initialization
-Loader() {}
-```
-
-**17.** Des fonctions virtuelles.
-
-Si la classe n'est pas destinée à une utilisation polymorphe, vous n'avez pas besoin de rendre les fonctions virtuelles. Ceci s'applique également pour le destructeur.
-
-**18.** Encodage.
-
-Utilisez UTF-8 partout. Utiliser `std::string`et`char *`. Ne pas utiliser de `std::wstring`et`wchar_t`.
-
-**19.** Journalisation.
-
-Voir les exemples partout dans le code.
-
-Avant de valider, supprimez toute journalisation sans signification et de débogage, ainsi que tout autre type de sortie de débogage.
-
-L'enregistrement des cycles doit être évité, même au niveau de la Trace.
-
-Les journaux doivent être lisibles à tout niveau d'enregistrement.
-
-La journalisation ne doit être utilisée que dans le code de l'application, pour la plupart.
-
-Les messages du journal doivent être écrits en anglais.
-
-Le journal devrait de préférence être compréhensible pour l'administrateur système.
-
-N'utilisez pas de blasphème dans le journal.
-
-Utilisez L'encodage UTF-8 dans le journal. Dans de rares cas, vous pouvez utiliser des caractères non-ASCII dans le journal.
-
-**20.** D'entrée-sortie.
-
-Ne pas utiliser de `iostreams` dans les cycles internes qui sont critiques pour les performances de l'application (et ne jamais utiliser `stringstream`).
-
-L'utilisation de la `DB/IO` la bibliothèque la place.
-
-**21.** La Date et l'heure.
-
-Voir la `DateLUT` bibliothèque.
-
-**22.** comprendre.
-
-Toujours utiliser `#pragma once` au lieu d'inclure des gardes.
-
-**23.** utiliser.
-
-`using namespace` n'est pas utilisé. Vous pouvez utiliser `using` avec quelque chose de spécifique. Mais faire local à l'intérieur d'une classe ou d'une fonction.
-
-**24.** Ne pas utiliser de `trailing return type` pour les fonctions, sauf si nécessaire.
-
-``` cpp
-auto f() -> void
-```
-
-**25.** Déclaration et initialisation des variables.
-
-``` cpp
-//right way
-std::string s = "Hello";
-std::string s{"Hello"};
-
-//wrong way
-auto s = std::string{"Hello"};
-```
-
-**26.** Pour les fonctions virtuelles, écrire `virtual` dans la classe de base, mais d'écrire `override` plutôt `virtual` dans les classes descendantes.
-
-## Fonctionnalités inutilisées de C++ {#unused-features-of-c}
-
-**1.** L'héritage virtuel n'est pas utilisé.
-
-**2.** Les spécificateurs d'Exception de C++03 ne sont pas utilisés.
-
-## Plate {#platform}
-
-**1.** Nous écrivons du code pour une plate-forme spécifique.
-
-Mais toutes choses étant égales par ailleurs, le code multi-plateforme ou portable est préféré.
-
-**2.** Langue: C++20.
-
-**3.** Compilateur: `gcc`. En ce moment (août 2020), le code est compilé en utilisant la version 9.3. (Il peut également être compilé en utilisant `clang 8`.)
-
-La bibliothèque standard est utilisée (`libc++`).
-
-**4.**OS: Linux Ubuntu, pas plus vieux que précis.
-
-**5.**Le Code est écrit pour l'architecture CPU x86_64.
-
-Le jeu D'instructions CPU est l'ensemble minimum pris en charge parmi nos serveurs. Actuellement, il s'agit de SSE 4.2.
-
-**6.** Utiliser `-Wall -Wextra -Werror` drapeaux de compilation.
-
-**7.** Utilisez la liaison statique avec toutes les bibliothèques sauf celles qui sont difficiles à connecter statiquement (voir la sortie de la `ldd` commande).
-
-**8.** Le Code est développé et débogué avec les paramètres de version.
-
-## Outils {#tools}
-
-**1.** KDevelop est un bon IDE.
-
-**2.** Pour le débogage, utilisez `gdb`, `valgrind` (`memcheck`), `strace`, `-fsanitize=...`, ou `tcmalloc_minimal_debug`.
-
-**3.** Pour le profilage, utilisez `Linux Perf`, `valgrind` (`callgrind`), ou `strace -cf`.
-
-**4.** Les Sources sont dans Git.
-
-**5.** Assemblée utilise `CMake`.
-
-**6.** Les programmes sont libérés en utilisant `deb` paquet.
-
-**7.** Les Commits à master ne doivent pas casser la construction.
-
-Bien que seules les révisions sélectionnées soient considérées comme réalisables.
-
-**8.** Faire s'engage aussi souvent que possible, même si le code n'est que partiellement prêt.
-
-Utilisez des branches à cet effet.
-
-Si votre code dans le `master` la branche n'est pas constructible pourtant, l'exclure de la construction avant que le `push`. Vous devrez le terminer ou l'enlever dans quelques jours.
-
-**9.** Pour les modifications non triviales, utilisez les branches et publiez-les sur le serveur.
-
-**10.** Le code inutilisé est supprimé du référentiel.
-
-## Bibliothèque {#libraries}
-
-**1.** La bibliothèque standard C++20 est utilisée (les extensions expérimentales sont autorisées), ainsi que `boost` et `Poco` Framework.
-
-**2.** Si nécessaire, vous pouvez utiliser toutes les bibliothèques bien connues disponibles dans le package OS.
-
-S'il existe déjà une bonne solution, utilisez-la, même si cela signifie que vous devez installer une autre bibliothèque.
-
-(Mais soyez prêt à supprimer les mauvaises bibliothèques du code.)
-
-**3.** Vous pouvez installer une bibliothèque qui n'est pas dans les paquets, les paquets n'ont pas ce que vous souhaitez ou avez une version périmée ou le mauvais type de compilation.
-
-**4.** Si la Bibliothèque est petite et n'a pas son propre système de construction complexe, placez les fichiers source dans le `contrib` dossier.
-
-**5.** La préférence est toujours donnée aux bibliothèques déjà utilisées.
-
-## Recommandations Générales {#general-recommendations-1}
-
-**1.** Écrivez aussi peu de code que possible.
-
-**2.** Essayez la solution la plus simple.
-
-**3.** N'écrivez pas de code tant que vous ne savez pas comment cela va fonctionner et comment la boucle interne fonctionnera.
-
-**4.** Dans les cas les plus simples, utilisez `using` au lieu de classes ou des structures.
-
-**5.** Si possible, n'écrivez pas de constructeurs de copie, d'opérateurs d'affectation, de destructeurs (autres que Virtuels, si la classe contient au moins une fonction virtuelle), de constructeurs de déplacement ou d'opérateurs d'affectation de déplacement. En d'autres termes, les fonctions générées par le compilateur doivent fonctionner correctement. Vous pouvez utiliser `default`.
-
-**6.** La simplification du Code est encouragée. Réduire la taille de votre code si possible.
-
-## Recommandations Supplémentaires {#additional-recommendations}
-
-**1.** Spécifier explicitement `std::` pour les types de `stddef.h`
-
-n'est pas recommandé. En d'autres termes, nous vous recommandons d'écriture `size_t` plutôt `std::size_t` parce que c'est plus court.
-
-Il est acceptable d'ajouter `std::`.
-
-**2.** Spécifier explicitement `std::` pour les fonctions de la bibliothèque C standard
-
-n'est pas recommandé. En d'autres termes, écrire `memcpy` plutôt `std::memcpy`.
-
-La raison en est qu'il existe des fonctions non standard similaires, telles que `memmem`. Nous utilisons ces fonctions à l'occasion. Ces fonctions n'existent pas dans `namespace std`.
-
-Si vous écrivez `std::memcpy` plutôt `memcpy` partout, puis `memmem` sans `std::` va sembler étrange.
-
-Néanmoins, vous pouvez toujours utiliser `std::` si vous le souhaitez.
-
-**3.** Utilisation des fonctions de C lorsque les mêmes sont disponibles dans la bibliothèque C++ standard.
-
-Ceci est acceptable s'il est plus efficace.
-
-Par exemple, l'utilisation `memcpy` plutôt `std::copy` pour copier de gros morceaux de mémoire.
-
-**4.** Arguments de fonction multiligne.
-
-L'un des styles d'emballage suivants est autorisé:
-
-``` cpp
-function(
-  T1 x1,
-  T2 x2)
-```
-
-``` cpp
-function(
-  size_t left, size_t right,
-  const & RangesInDataParts ranges,
-  size_t limit)
-```
-
-``` cpp
-function(size_t left, size_t right,
-  const & RangesInDataParts ranges,
-  size_t limit)
-```
-
-``` cpp
-function(size_t left, size_t right,
-      const & RangesInDataParts ranges,
-      size_t limit)
-```
-
-``` cpp
-function(
-      size_t left,
-      size_t right,
-      const & RangesInDataParts ranges,
-      size_t limit)
-```

-# Moteurs De Table {#table_engines}
-
-Le moteur de table (type de table) détermine:
-
--   Comment et où les données sont stockées, où les écrire et où les lire.
--   Quelles requêtes sont prises en charge et comment.
--   Accès simultané aux données.
--   Utilisation des index, si elle est présente.
--   Indique si l'exécution d'une requête multithread est possible.
--   Paramètres de réplication des données.
-
-## Familles De Moteurs {#engine-families}

-## Les Colonnes Virtuelles {#table_engines-virtual_columns}
-
-Colonne virtuelle est un attribut de moteur de table intégrale qui est défini dans le code source du moteur.
-
-Vous ne devez pas spécifier de colonnes virtuelles dans `CREATE TABLE` requête et vous ne pouvez pas les voir dans `SHOW CREATE TABLE` et `DESCRIBE TABLE` les résultats de la requête. Les colonnes virtuelles sont également en lecture seule, vous ne pouvez donc pas insérer de données dans des colonnes virtuelles.
-
-Pour sélectionner des données dans une colonne virtuelle, vous devez spécifier son nom `SELECT` requête. `SELECT *` ne renvoie pas de valeurs à partir de colonnes virtuelles.
-
-Si vous créez une table avec une colonne portant le même nom que l'une des colonnes virtuelles de la table, la colonne virtuelle devient inaccessible. Nous ne recommandons pas de faire cela. Pour éviter les conflits, les noms de colonnes virtuelles sont généralement précédés d'un trait de soulignement.

-toc_title: HDFS
----
-
-# HDFS {#table_engines-hdfs}
-
-Ce moteur fournit l'intégration avec [Apache Hadoop](https://en.wikipedia.org/wiki/Apache_Hadoop) l'écosystème en permettant de gérer les données sur [HDFS](https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html)via ClickHouse. Ce moteur est similaire
-à l' [Fichier](../special/file.md#table_engines-file) et [URL](../special/url.md#table_engines-url) moteurs, mais fournit des fonctionnalités spécifiques Hadoop.
-
-## Utilisation {#usage}
-
-``` sql
-ENGINE = HDFS(URI, format)
-```
-
-Le `URI` paramètre est L'URI du fichier entier dans HDFS.
-Le `format` paramètre spécifie l'un des formats de fichier disponibles. Effectuer
-`SELECT` requêtes, le format doit être pris en charge pour l'entrée, et à effectuer
-`INSERT` queries – for output. The available formats are listed in the
-[Format](../../../interfaces/formats.md#formats) section.
-Le chemin le cadre de `URI` peut contenir des globules. Dans ce cas, le tableau serait en lecture seule.
-
-**Exemple:**
-
-**1.** Configurer le `hdfs_engine_table` table:
-
-``` sql
-CREATE TABLE hdfs_engine_table (name String, value UInt32) ENGINE=HDFS('hdfs://hdfs1:9000/other_storage', 'TSV')
-```
-
-**2.** Remplir le fichier:
-
-``` sql
-INSERT INTO hdfs_engine_table VALUES ('one', 1), ('two', 2), ('three', 3)
-```
-
-**3.** Interroger les données:
-
-``` sql
-SELECT * FROM hdfs_engine_table LIMIT 2
-```
-
-``` text
-┌─name─┬─value─┐
-│ one  │     1 │
-│ two  │     2 │
-└──────┴───────┘
-```
-
-## Détails De Mise En Œuvre {#implementation-details}
-
--   Les lectures et les écritures peuvent être parallèles
--   Pas pris en charge:
-    -   `ALTER` et `SELECT...SAMPLE` opérations.
-    -   Index.
-    -   Réplication.
-
-**Globs dans le chemin**
-
-Plusieurs composants de chemin peuvent avoir des globs. Pour être traité, le fichier devrait exister et correspondre au modèle de chemin entier. Liste des fichiers détermine pendant `SELECT` (pas à l' `CREATE` moment).
-
--   `*` — Substitutes any number of any characters except `/` y compris la chaîne vide.
--   `?` — Substitutes any single character.
--   `{some_string,another_string,yet_another_one}` — Substitutes any of strings `'some_string', 'another_string', 'yet_another_one'`.
--   `{N..M}` — Substitutes any number in range from N to M including both borders.
-
-Les Constructions avec `{}` sont similaires à l' [distant](../../../sql-reference/table-functions/remote.md) table de fonction.
-
-**Exemple**
-
-1.  Supposons que nous ayons plusieurs fichiers au format TSV avec les URI suivants sur HDFS:
-
--   ‘hdfs://hdfs1:9000/some_dir/some_file_1’
--   ‘hdfs://hdfs1:9000/some_dir/some_file_2’
--   ‘hdfs://hdfs1:9000/some_dir/some_file_3’
--   ‘hdfs://hdfs1:9000/another_dir/some_file_1’
--   ‘hdfs://hdfs1:9000/another_dir/some_file_2’
--   ‘hdfs://hdfs1:9000/another_dir/some_file_3’
-
-1.  Il y a plusieurs façons de faire une table composée des six fichiers:
-
-<!-- -->
-
-``` sql
-CREATE TABLE table_with_range (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/{some,another}_dir/some_file_{1..3}', 'TSV')
-```
-
-Une autre façon:
-
-``` sql
-CREATE TABLE table_with_question_mark (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/{some,another}_dir/some_file_?', 'TSV')
-```
-
-Table se compose de tous les fichiers dans les deux répertoires (tous les fichiers doivent satisfaire le format et le schéma décrits dans la requête):
-
-``` sql
-CREATE TABLE table_with_asterisk (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/{some,another}_dir/*', 'TSV')
-```
-
-!!! warning "Avertissement"
-    Si la liste des fichiers contient des plages de nombres avec des zéros en tête, utilisez la construction avec des accolades pour chaque chiffre séparément ou utilisez `?`.
-
-**Exemple**
-
-Créer une table avec des fichiers nommés `file000`, `file001`, … , `file999`:
-
-``` sql
-CREARE TABLE big_table (name String, value UInt32) ENGINE = HDFS('hdfs://hdfs1:9000/big_dir/file{0..9}{0..9}{0..9}', 'CSV')
-```
-
-## Les Colonnes Virtuelles {#virtual-columns}
-
--   `_path` — Path to the file.
--   `_file` — Name of the file.

-# JDBC {#table-engine-jdbc}
-
-Permet à ClickHouse de se connecter à des bases de données externes via [JDBC](https://en.wikipedia.org/wiki/Java_Database_Connectivity).
-
-Pour implémenter la connexion JDBC, ClickHouse utilise le programme séparé [clickhouse-JDBC-pont](https://github.com/alex-krash/clickhouse-jdbc-bridge) cela devrait fonctionner comme un démon.
-
-Ce moteur prend en charge le [Nullable](../../../sql-reference/data-types/nullable.md) type de données.
-
-## Création d'une Table {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name
-(
-    columns list...
-)
-ENGINE = JDBC(dbms_uri, external_database, external_table)
-```
-
-**Les Paramètres Du Moteur**
-
--   `dbms_uri` — URI of an external DBMS.
-
-    Format: `jdbc:<driver_name>://<host_name>:<port>/?user=<username>&password=<password>`.
-    Exemple pour MySQL: `jdbc:mysql://localhost:3306/?user=root&password=root`.
-
--   `external_database` — Database in an external DBMS.
-
--   `external_table` — Name of the table in `external_database`.
-
-## Exemple D'Utilisation {#usage-example}
-
-Création d'une table dans le serveur MySQL en se connectant directement avec son client console:
-
-``` text
-mysql> CREATE TABLE `test`.`test` (
-    ->   `int_id` INT NOT NULL AUTO_INCREMENT,
-    ->   `int_nullable` INT NULL DEFAULT NULL,
-    ->   `float` FLOAT NOT NULL,
-    ->   `float_nullable` FLOAT NULL DEFAULT NULL,
-    ->   PRIMARY KEY (`int_id`));
-Query OK, 0 rows affected (0,09 sec)
-
-mysql> insert into test (`int_id`, `float`) VALUES (1,2);
-Query OK, 1 row affected (0,00 sec)
-
-mysql> select * from test;
-+------+----------+-----+----------+
-| int_id | int_nullable | float | float_nullable |
-+------+----------+-----+----------+
-|      1 |         NULL |     2 |           NULL |
-+------+----------+-----+----------+
-1 row in set (0,00 sec)
-```
-
-Création d'une table dans le serveur ClickHouse et sélection des données:
-
-``` sql
-CREATE TABLE jdbc_table
-(
-    `int_id` Int32,
-    `int_nullable` Nullable(Int32),
-    `float` Float32,
-    `float_nullable` Nullable(Float32)
-)
-ENGINE JDBC('jdbc:mysql://localhost:3306/?user=root&password=root', 'test', 'test')
-```
-
-``` sql
-SELECT *
-FROM jdbc_table
-```
-
-``` text
-┌─int_id─┬─int_nullable─┬─float─┬─float_nullable─┐

----
-
-# Kafka {#kafka}
-
-Ce moteur fonctionne avec [Apache Kafka](http://kafka.apache.org/).
-
-Kafka vous permet de:
-
--   Publier ou s'abonner aux flux de données.
--   Organiser le stockage tolérant aux pannes.
--   Traiter les flux à mesure qu'ils deviennent disponibles.
-
-## Création d'une Table {#table_engine-kafka-creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = Kafka()
-SETTINGS
-    kafka_broker_list = 'host:port',
-    kafka_topic_list = 'topic1,topic2,...',
-    kafka_group_name = 'group_name',
-    kafka_format = 'data_format'[,]
-    [kafka_row_delimiter = 'delimiter_symbol',]
-    [kafka_schema = '',]
-    [kafka_num_consumers = N,]
-    [kafka_max_block_size = 0,]
-    [kafka_skip_broken_messages = N,]
-    [kafka_commit_every_batch = 0]
-```
-
-Les paramètres requis:
-
--   `kafka_broker_list` – A comma-separated list of brokers (for example, `localhost:9092`).
--   `kafka_topic_list` – A list of Kafka topics.
--   `kafka_group_name` – A group of Kafka consumers. Reading margins are tracked for each group separately. If you don't want messages to be duplicated in the cluster, use the same group name everywhere.
--   `kafka_format` – Message format. Uses the same notation as the SQL `FORMAT` la fonction, tels que `JSONEachRow`. Pour plus d'informations, voir le [Format](../../../interfaces/formats.md) section.
-
-Paramètres facultatifs:
-
--   `kafka_row_delimiter` – Delimiter character, which ends the message.
--   `kafka_schema` – Parameter that must be used if the format requires a schema definition. For example, [Cap'n Proto](https://capnproto.org/) nécessite le chemin d'accès du fichier de schéma et le nom de la racine `schema.capnp:Message` objet.
--   `kafka_num_consumers` – The number of consumers per table. Default: `1`. Spécifiez plus de consommateurs si le débit d'un consommateur est insuffisant. Le nombre total de consommateurs ne doit pas dépasser le nombre de partitions dans la rubrique, car un seul consommateur peut être affecté par partition.
--   `kafka_max_block_size` - La taille maximale du lot (dans les messages) pour le sondage (par défaut: `max_block_size`).
--   `kafka_skip_broken_messages` – Kafka message parser tolerance to schema-incompatible messages per block. Default: `0`. Si `kafka_skip_broken_messages = N` puis le moteur saute *N* Messages Kafka qui ne peuvent pas être analysés (un message est égal à une ligne de données).
--   `kafka_commit_every_batch` - Commit chaque lot consommé et traité au lieu d'un seul commit après avoir écrit un bloc entier (par défaut: `0`).
-
-Exemple:
-
-``` sql
-  CREATE TABLE queue (
-    timestamp UInt64,
-    level String,
-    message String
-  ) ENGINE = Kafka('localhost:9092', 'topic', 'group1', 'JSONEachRow');
-
-  SELECT * FROM queue LIMIT 5;
-
-  CREATE TABLE queue2 (
-    timestamp UInt64,
-    level String,
-    message String
-  ) ENGINE = Kafka SETTINGS kafka_broker_list = 'localhost:9092',
-                            kafka_topic_list = 'topic',
-                            kafka_group_name = 'group1',
-                            kafka_format = 'JSONEachRow',
-                            kafka_num_consumers = 4;
-
-  CREATE TABLE queue2 (
-    timestamp UInt64,
-    level String,
-    message String
-  ) ENGINE = Kafka('localhost:9092', 'topic', 'group1')
-              SETTINGS kafka_format = 'JSONEachRow',

-## Description {#description}
-
-Les messages livrés sont suivis automatiquement, de sorte que chaque message d'un groupe n'est compté qu'une seule fois. Si vous souhaitez obtenir les données deux fois, créez une copie de la table avec un autre nom de groupe.
-
-Les groupes sont flexibles et synchronisés sur le cluster. Par exemple, si vous avez 10 thèmes et 5 copies d'une table dans un cluster, chaque copie obtient 2 sujets. Si le nombre de copies change, les rubriques sont redistribuées automatiquement entre les copies. En savoir plus à ce sujet à http://kafka.apache.org/intro.
-
-`SELECT` n'est pas particulièrement utile pour la lecture de messages (sauf pour le débogage), car chaque message ne peut être lu qu'une seule fois. Il est plus pratique de créer des threads en temps réel à l'aide de vues matérialisées. Pour ce faire:
-
-1.  Utilisez le moteur pour créer un consommateur Kafka et considérez-le comme un flux de données.
-2.  Créez une table avec la structure souhaitée.
-3.  Créer une vue matérialisée qui convertit les données du moteur et le met dans une table créée précédemment.
-
-Lorsque l' `MATERIALIZED VIEW` rejoint le moteur, il commence à collecter des données en arrière-plan. Cela vous permet de recevoir continuellement des messages de Kafka et de les convertir au format requis en utilisant `SELECT`.
-Une table kafka peut avoir autant de vues matérialisées que vous le souhaitez, elles ne lisent pas directement les données de la table kafka, mais reçoivent de nouveaux enregistrements( en blocs), de cette façon vous pouvez écrire sur plusieurs tables avec différents niveaux de détail (avec regroupement - agrégation et sans).
-
-Exemple:
-
-``` sql
-  CREATE TABLE queue (
-    timestamp UInt64,
-    level String,
-    message String
-  ) ENGINE = Kafka('localhost:9092', 'topic', 'group1', 'JSONEachRow');
-
-  CREATE TABLE daily (
-    day Date,
-    level String,
-    total UInt64
-  ) ENGINE = SummingMergeTree(day, (day, level), 8192);
-
-  CREATE MATERIALIZED VIEW consumer TO daily
-    AS SELECT toDate(toDateTime(timestamp)) AS day, level, count() as total
-    FROM queue GROUP BY day, level;
-
-  SELECT level, sum(total) FROM daily GROUP BY level;
-```
-
-Pour améliorer les performances, les messages reçus sont regroupées en blocs de la taille de [max_insert_block_size](../../../operations/server-configuration-parameters/settings.md#settings-max_insert_block_size). Si le bloc n'a pas été formé à l'intérieur [stream_flush_interval_ms](../../../operations/server-configuration-parameters/settings.md) millisecondes, les données seront vidées dans le tableau, indépendamment de l'intégralité du bloc.
-
-Pour arrêter de recevoir des données de rubrique ou pour modifier la logique de conversion, détachez la vue matérialisée:
-
-``` sql
-  DETACH TABLE consumer;
-  ATTACH TABLE consumer;
-```
-
-Si vous souhaitez modifier la table cible en utilisant `ALTER`, nous vous recommandons de désactiver la vue matériel pour éviter les divergences entre la table cible et les données de la vue.
-
-## Configuration {#configuration}
-
-Similaire à GraphiteMergeTree, le moteur Kafka prend en charge la configuration étendue à l'aide du fichier de configuration ClickHouse. Il y a deux clés de configuration que vous pouvez utiliser: global (`kafka`) et des rubriques (`kafka_*`). La configuration globale est appliquée en premier, puis la configuration au niveau de la rubrique est appliquée (si elle existe).
-
-``` xml
-  <!-- Global configuration options for all tables of Kafka engine type -->
-  <kafka>
-    <debug>cgrp</debug>
-    <auto_offset_reset>smallest</auto_offset_reset>
-  </kafka>
-
-  <!-- Configuration specific for topic "logs" -->
-  <kafka_logs>
-    <retry_backoff_ms>250</retry_backoff_ms>
-    <fetch_min_bytes>100000</fetch_min_bytes>
-  </kafka_logs>
-```
-
-Pour obtenir une liste des options de configuration possibles, consultez [librdkafka référence de configuration](https://github.com/edenhill/librdkafka/blob/master/CONFIGURATION.md). Utilisez le trait de soulignement (`_`) au lieu d'un point dans la configuration ClickHouse. Exemple, `check.crcs=true` sera `<check_crcs>true</check_crcs>`.
-
-## Les Colonnes Virtuelles {#virtual-columns}
-
--   `_topic` — Kafka topic.
--   `_key` — Key of the message.
--   `_offset` — Offset of the message.
--   `_timestamp` — Timestamp of the message.
--   `_partition` — Partition of Kafka topic.

-# Mysql {#mysql}
-
-Le moteur MySQL vous permet d'effectuer `SELECT` requêtes sur les données stockées sur un serveur MySQL distant.
-
-## Création d'une Table {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
-    ...
-) ENGINE = MySQL('host:port', 'database', 'table', 'user', 'password'[, replace_query, 'on_duplicate_clause']);
-```
-
-Voir une description détaillée de la [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) requête.
-
-La structure de la table peut différer de la structure de la table MySQL d'origine:
-
--   Les noms de colonnes doivent être les mêmes que dans la table MySQL d'origine, mais vous pouvez utiliser seulement certaines de ces colonnes et dans n'importe quel ordre.
--   Les types de colonnes peuvent différer de ceux de la table MySQL d'origine. ClickHouse essaie de [jeter](../../../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) valeurs des types de données ClickHouse.
-
-**Les Paramètres Du Moteur**
-
--   `host:port` — MySQL server address.
-
--   `database` — Remote database name.
-
--   `table` — Remote table name.
-
--   `user` — MySQL user.
-
--   `password` — User password.
-
--   `replace_query` — Flag that converts `INSERT INTO` les requêtes de `REPLACE INTO`. Si `replace_query=1` la requête est substitué.
-
--   `on_duplicate_clause` — The `ON DUPLICATE KEY on_duplicate_clause` expression qui est ajoutée à la `INSERT` requête.
-
-    Exemple: `INSERT INTO t (c1,c2) VALUES ('a', 2) ON DUPLICATE KEY UPDATE c2 = c2 + 1`, où `on_duplicate_clause` être `UPDATE c2 = c2 + 1`. Voir la [Documentation de MySQL](https://dev.mysql.com/doc/refman/8.0/en/insert-on-duplicate.html) pour trouver lequel `on_duplicate_clause` vous pouvez utiliser avec le `ON DUPLICATE KEY` clause.
-
-    Spécifier `on_duplicate_clause` vous avez besoin de passer `0` à l' `replace_query` paramètre. Si vous passez simultanément `replace_query = 1` et `on_duplicate_clause`, Clickhouse génère une exception.
-
-Simple `WHERE` des clauses telles que `=, !=, >, >=, <, <=` sont exécutés sur le serveur MySQL.
-
-Le reste des conditions et le `LIMIT` les contraintes d'échantillonnage sont exécutées dans ClickHouse uniquement après la fin de la requête à MySQL.
-
-## Exemple D'Utilisation {#usage-example}
-
-Table dans MySQL:
-
-``` text

-    ->   `float_nullable` FLOAT NULL DEFAULT NULL,
-    ->   PRIMARY KEY (`int_id`));
-Query OK, 0 rows affected (0,09 sec)
-
-mysql> insert into test (`int_id`, `float`) VALUES (1,2);
-Query OK, 1 row affected (0,00 sec)

-# ODBC {#table-engine-odbc}
-
-Permet à ClickHouse de se connecter à des bases de données externes via [ODBC](https://en.wikipedia.org/wiki/Open_Database_Connectivity).
-
-Pour implémenter en toute sécurité les connexions ODBC, ClickHouse utilise un programme distinct `clickhouse-odbc-bridge`. Si le pilote ODBC est chargé directement depuis `clickhouse-server`, les problèmes de pilote peuvent planter le serveur ClickHouse. Clickhouse démarre automatiquement `clickhouse-odbc-bridge` lorsque cela est nécessaire. Le programme ODBC bridge est installé à partir du même package que `clickhouse-server`.

-## Exemple D'Utilisation {#usage-example}
-
-**Récupération des données de L'installation MySQL locale via ODBC**
-
-Cet exemple est vérifié pour Ubuntu Linux 18.04 et MySQL server 5.7.
-
-Assurez-vous que unixODBC et MySQL Connector sont installés.
-
-Par défaut (si installé à partir de paquets), ClickHouse démarre en tant qu'utilisateur `clickhouse`. Ainsi, vous devez créer et configurer cet utilisateur dans le serveur MySQL.
-
-``` bash
-$ sudo mysql
-```
-
-``` sql
-mysql> CREATE USER 'clickhouse'@'localhost' IDENTIFIED BY 'clickhouse';
-mysql> GRANT ALL PRIVILEGES ON *.* TO 'clickhouse'@'clickhouse' WITH GRANT OPTION;
-```
-
-Puis configurez la connexion dans `/etc/odbc.ini`.
-
-``` bash
-$ cat /etc/odbc.ini
-[mysqlconn]
-DRIVER = /usr/local/lib/libmyodbc5w.so
-SERVER = 127.0.0.1
-PORT = 3306
-DATABASE = test
-USERNAME = clickhouse
-PASSWORD = clickhouse
-```
-
-Vous pouvez vérifier la connexion en utilisant le `isql` utilitaire de l'installation unixODBC.
-
-``` bash
-$ isql -v mysqlconn

----
-
-# Famille De Moteurs En Rondins {#log-engine-family}
-
-Ces moteurs ont été développés pour les scénarios où vous devez écrire rapidement de nombreuses petites tables (jusqu'à environ 1 million de lignes) et les lire plus tard dans leur ensemble.
-
-Les moteurs de la famille:
-
--   [StripeLog](stripelog.md)
--   [Journal](log.md)
--   [TinyLog](tinylog.md)
-
-## Propriétés Communes {#common-properties}
-
-Moteur:
-
--   Stocker des données sur un disque.
-
--   Ajouter des données à la fin du fichier lors de l'écriture.
-
--   Bloque simultanées dans l'accès aux données.
-
-    Lors `INSERT` requêtes, la table est verrouillée, et d'autres requêtes pour la lecture et l'écriture de données attendent que la table se déverrouille. S'il n'y a pas de requêtes d'écriture de données, un certain nombre de requêtes de lecture de données peuvent être effectuées simultanément.
-
--   Ne prennent pas en charge [mutation](../../../sql-reference/statements/alter.md#alter-mutations) opérations.
-
--   Ne prennent pas en charge les index.
-
-    Cela signifie que `SELECT` les requêtes pour les plages de données ne sont pas efficaces.
-
--   N'écrivez pas de données de manière atomique.
-
-    Vous pouvez obtenir une table avec des données corrompues si quelque chose interrompt l'opération d'écriture, par exemple, un arrêt anormal du serveur.
-
-## Différence {#differences}
-
-Le `TinyLog` le moteur est le plus simple de la famille et offre la fonctionnalité la plus pauvre et la plus faible efficacité. Le `TinyLog` le moteur ne prend pas en charge la lecture de données parallèles par plusieurs threads. Il lit les données plus lentement que les autres moteurs de la famille qui prennent en charge la lecture parallèle et utilise presque autant de descripteurs que `Log` moteur, car il stocke chaque colonne dans un fichier séparé. Utilisez-le dans des scénarios simples à faible charge.
-
-Le `Log` et `StripeLog` les moteurs prennent en charge la lecture de données parallèle. Lors de la lecture de données, ClickHouse utilise plusieurs threads. Chaque thread traite un bloc de données séparé. Le `Log` le moteur utilise un fichier distinct pour chaque colonne de la table. `StripeLog` stocke toutes les données dans un seul fichier. En conséquence, la `StripeLog` moteur utilise moins de descripteurs dans le système d'exploitation, mais le `Log` moteur fournit une plus grande efficacité lors de la lecture des données.

----
-
-# Journal {#log}
-
-Moteur appartient à la famille de journal des moteurs. Voir les propriétés communes des moteurs de journal et leurs différences dans le [Famille De Moteurs En Rondins](index.md) article.
-
-Journal diffère de [TinyLog](tinylog.md) dans un petit fichier de “marks” réside avec les fichiers de colonne. Ces marques sont écrites sur chaque bloc de données et contiennent des décalages qui indiquent où commencer à lire le fichier afin d'ignorer le nombre de lignes spécifié. Cela permet de lire les données de table dans plusieurs threads.
-Pour l'accès aux données simultanées, les opérations de lecture peuvent être effectuées simultanément, tandis que les opérations d'écriture bloc lit et l'autre.
-Le moteur de journal ne prend pas en charge les index. De même, si l'écriture dans une table a échoué, la table est cassée et la lecture de celle-ci renvoie une erreur. Le moteur de journal est approprié pour les données temporaires, les tables en écriture unique, et à des fins de test ou de démonstration.

-
-# Stripelog {#stripelog}
-
-Ce moteur appartient à la famille des moteurs en rondins. Voir les propriétés communes des moteurs de journal et leurs différences dans le [Famille De Moteurs En Rondins](index.md) article.
-
-Utilisez ce moteur dans des scénarios lorsque vous devez écrire de nombreuses tables avec une petite quantité de données (moins de 1 million de lignes).
-
-## Création d'une Table {#table_engines-stripelog-creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    column1_name [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    column2_name [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = StripeLog
-```
-
-Voir la description détaillée de la [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) requête.
-
-## L'écriture des Données {#table_engines-stripelog-writing-the-data}
-
-Le `StripeLog` moteur stocke toutes les colonnes dans un fichier. Pour chaque `INSERT` requête, ClickHouse ajoute le bloc de données à la fin d'un fichier de table, en écrivant des colonnes une par une.
-
-Pour chaque table ClickHouse écrit les fichiers:
-
--   `data.bin` — Data file.
--   `index.mrk` — File with marks. Marks contain offsets for each column of each data block inserted.
-
-Le `StripeLog` moteur ne prend pas en charge la `ALTER UPDATE` et `ALTER DELETE` opérations.
-
-## La lecture des Données {#table_engines-stripelog-reading-the-data}
-
-Le fichier avec des marques permet à ClickHouse de paralléliser la lecture des données. Cela signifie qu'une `SELECT` la requête renvoie des lignes dans un ordre imprévisible. L'utilisation de la `ORDER BY` clause pour trier les lignes.
-
-## Exemple D'utilisation {#table_engines-stripelog-example-of-use}
-
-Création d'une table:
-
-``` sql
-CREATE TABLE stripe_log_table
-(
-    timestamp DateTime,
-    message_type String,
-    message String
-)
-ENGINE = StripeLog
-```
-
-Insertion de données:
-
-``` sql
-INSERT INTO stripe_log_table VALUES (now(),'REGULAR','The first regular message')
-INSERT INTO stripe_log_table VALUES (now(),'REGULAR','The second regular message'),(now(),'WARNING','The first warning message')
-```
-
-Nous avons utilisé deux `INSERT` requêtes pour créer deux blocs de données `data.bin` fichier.
-
-ClickHouse utilise plusieurs threads lors de la sélection des données. Chaque thread lit un bloc de données séparé et renvoie les lignes résultantes indépendamment à la fin. En conséquence, l'ordre des blocs de lignes dans le résultat ne correspond pas à l'ordre des mêmes blocs dans l'entrée, dans la plupart des cas. Exemple:
-
-``` sql
-SELECT * FROM stripe_log_table
-```
-
-``` text
-┌───────────timestamp─┬─message_type─┬─message────────────────────┐
-│ 2019-01-18 14:27:32 │ REGULAR      │ The second regular message │
-│ 2019-01-18 14:34:53 │ WARNING      │ The first warning message  │
-└─────────────────────┴──────────────┴────────────────────────────┘
-┌───────────timestamp─┬─message_type─┬─message───────────────────┐
-│ 2019-01-18 14:23:43 │ REGULAR      │ The first regular message │
-└─────────────────────┴──────────────┴───────────────────────────┘
-```
-
-Trier les résultats (ordre croissant par défaut):
-
-``` sql
-SELECT * FROM stripe_log_table ORDER BY timestamp
-```
-
-``` text
-┌───────────timestamp─┬─message_type─┬─message────────────────────┐
-│ 2019-01-18 14:23:43 │ REGULAR      │ The first regular message  │
-│ 2019-01-18 14:27:32 │ REGULAR      │ The second regular message │
-│ 2019-01-18 14:34:53 │ WARNING      │ The first warning message  │
-└─────────────────────┴──────────────┴────────────────────────────┘

-# TinyLog {#tinylog}
-
-Le moteur appartient à la famille de moteurs en rondins. Voir [Famille De Moteurs En Rondins](index.md) pour les propriétés communes des moteurs en rondins et leurs différences.
-
-Ce moteur de table est généralement utilisé avec la méthode write-once: écrivez des données une fois, puis lisez-les autant de fois que nécessaire. Par exemple, vous pouvez utiliser `TinyLog`- tapez des tables pour les données intermédiaires qui sont traitées en petits lots. Notez que le stockage des données dans un grand nombre de petites tables est inefficace.
-
-Les requêtes sont exécutées dans un flux unique. En d'autres termes, ce moteur est destiné à des tables relativement petites (jusqu'à environ 1 000 000 de lignes). Il est logique d'utiliser ce moteur de table si vous avez beaucoup de petites tables, car il est plus simple que le [Journal](log.md) moteur (moins de fichiers doivent être ouverts).

-# Aggregatingmergetree {#aggregatingmergetree}
-
-Le moteur hérite de [MergeTree](mergetree.md#table_engines-mergetree), modifier la logique pour les parties de données Fusion. ClickHouse remplace toutes les lignes avec la même clé primaire (ou, plus précisément, avec la même [clé de tri](mergetree.md)) avec une seule ligne (dans un rayon d'une partie des données) qui stocke une combinaison d'états de fonctions d'agrégation.
-
-Vous pouvez utiliser `AggregatingMergeTree` tables pour l'agrégation incrémentielle des données, y compris pour les vues matérialisées agrégées.
-
-Le moteur traite toutes les colonnes avec les types suivants:
-
--   [AggregateFunction](../../../sql-reference/data-types/aggregatefunction.md)
--   [SimpleAggregateFunction](../../../sql-reference/data-types/simpleaggregatefunction.md)
-
-Il est approprié d'utiliser `AggregatingMergeTree` si elle réduit le nombre de lignes par commande.
-
-## Création d'une Table {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = AggregatingMergeTree()
-[PARTITION BY expr]
-[ORDER BY expr]
-[SAMPLE BY expr]
-[TTL expr]
-[SETTINGS name=value, ...]
-```
-
-Pour une description des paramètres de requête, voir [demande de description](../../../sql-reference/statements/create.md).
-
-**Les clauses de requête**
-
-Lors de la création d'un `AggregatingMergeTree` la table de la même [clause](mergetree.md) sont nécessaires, comme lors de la création d'un `MergeTree` table.

-
-Tous les paramètres ont la même signification que dans `MergeTree`.
-</details>
-
-## Sélectionner et insérer {#select-and-insert}
-
-Pour insérer des données, utilisez [INSERT SELECT](../../../sql-reference/statements/insert-into.md) requête avec l'ensemble-l'État des fonctions.
-Lors de la sélection des données `AggregatingMergeTree` table, utilisez `GROUP BY` et les mêmes fonctions d'agrégat que lors de l'insertion de données, mais en utilisant `-Merge` suffixe.
-
-Dans les résultats de `SELECT` requête, les valeurs de `AggregateFunction` type ont une représentation binaire spécifique à l'implémentation pour tous les formats de sortie ClickHouse. Si les données de vidage dans, par exemple, `TabSeparated` format avec `SELECT` requête alors ce vidage peut être chargé en utilisant `INSERT` requête.
-
-## Exemple D'une vue matérialisée agrégée {#example-of-an-aggregated-materialized-view}
-
-`AggregatingMergeTree` vue matérialisée qui regarde le `test.visits` table:
-
-``` sql
-CREATE MATERIALIZED VIEW test.basic
-ENGINE = AggregatingMergeTree() PARTITION BY toYYYYMM(StartDate) ORDER BY (CounterID, StartDate)
-AS SELECT
-    CounterID,
-    StartDate,
-    sumState(Sign)    AS Visits,
-    uniqState(UserID) AS Users
-FROM test.visits
-GROUP BY CounterID, StartDate;
-```
-
-Insertion de données dans la `test.visits` table.
-
-``` sql
-INSERT INTO test.visits ...
-```
-
-Les données sont insérées dans la table et la vue `test.basic` que va effectuer l'agrégation.
-
-Pour obtenir les données agrégées, nous devons exécuter une requête telle que `SELECT ... GROUP BY ...` à partir de la vue `test.basic`:
-
-``` sql
-SELECT
-    StartDate,
-    sumMerge(Visits) AS Visits,
-    uniqMerge(Users) AS Users
-FROM test.basic
-GROUP BY StartDate
-ORDER BY StartDate;

Les lignes sans paire sont conservées. Pour plus de détails, voir le [Effondrer](#table_engine-collapsingmergetree-collapsing) la section du document.

-
-## Effondrer {#table_engine-collapsingmergetree-collapsing}
-
-### Données {#data}
-
-Considérez la situation où vous devez enregistrer des données en constante évolution pour un objet. Il semble logique d'avoir une ligne pour un objet et de la mettre à jour à tout changement, mais l'opération de mise à jour est coûteuse et lente pour le SGBD car elle nécessite une réécriture des données dans le stockage. Si vous avez besoin d'écrire des données rapidement, la mise à jour n'est pas acceptable, mais vous pouvez écrire les modifications d'un objet de manière séquentielle comme suit.
-
-Utilisez la colonne particulière `Sign`. Si `Sign = 1` cela signifie que la ligne est un état d'un objet, appelons-la “state” rangée. Si `Sign = -1` il signifie l'annulation de l'état d'un objet avec les mêmes attributs, nous allons l'appeler “cancel” rangée.
-
-Par exemple, nous voulons calculer combien de pages les utilisateurs ont vérifié sur un site et combien de temps ils étaient là. À un certain moment nous écrire la ligne suivante avec l'état de l'activité de l'utilisateur:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-À un moment donné, nous enregistrons le changement d'activité de l'utilisateur et l'écrivons avec les deux lignes suivantes.
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-La première ligne annule le précédent état de l'objet (utilisateur). Il doit copier les champs de clé de tri de l'état annulé sauf `Sign`.
-
-La deuxième ligne contient l'état actuel.
-
-Comme nous avons besoin seulement le dernier état de l'activité de l'utilisateur, les lignes
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-│ 4324182021466249494 │         5 │      146 │   -1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-peut être supprimé en réduisant l'état invalide (ancien) d'un objet. `CollapsingMergeTree` fait cela lors de la fusion des parties de données.
-
-Pourquoi nous avons besoin de 2 lignes pour chaque changement lu dans le [Algorithme](#table_engine-collapsingmergetree-collapsing-algorithm) paragraphe.
-
-**Propriétés particulières d'une telle approche**
-
-1.  Le programme qui écrit les données doit se souvenir de l'état d'un objet pour pouvoir l'annuler. “Cancel” string doit contenir des copies des champs de clé de tri du “state” chaîne et le contraire `Sign`. Il augmente la taille initiale de stockage, mais permet d'écrire les données rapidement.
-2.  Les tableaux de plus en plus longs dans les colonnes réduisent l'efficacité du moteur en raison de la charge pour l'écriture. Plus les données sont simples, plus l'efficacité est élevée.
-3.  Le `SELECT` les résultats dépendent fortement de la cohérence de l'historique des modifications d'objet. Être précis lors de la préparation des données pour l'insertion. Vous pouvez obtenir des résultats imprévisibles dans des données incohérentes, par exemple des valeurs négatives pour des mesures non négatives telles que la profondeur de session.
-
-### Algorithme {#table_engine-collapsingmergetree-collapsing-algorithm}
-
-Lorsque ClickHouse fusionne des parties de données, chaque groupe de lignes consécutives avec la même clé de tri (`ORDER BY`) est réduit à pas plus de deux rangées, une avec `Sign = 1` (“state” ligne) et l'autre avec `Sign = -1` (“cancel” rangée). En d'autres termes, les entrées de l'effondrement.
-
-Pour chaque partie de données résultante clickhouse enregistre:
-
-1.  Première “cancel” et la dernière “state” lignes, si le nombre de “state” et “cancel” lignes correspond et la dernière ligne est un “state” rangée.
-2.  La dernière “state” ligne, si il y a plus de “state” les lignes de “cancel” rangée.
-3.  Première “cancel” ligne, si il y a plus de “cancel” les lignes de “state” rangée.
-4.  Aucune des lignes, dans tous les autres cas.
-
-Aussi quand il y a au moins 2 plus “state” les lignes de “cancel” les lignes, ou au moins 2 de plus “cancel” rangs puis “state” la fusion continue, mais ClickHouse traite cette situation comme une erreur logique et l'enregistre dans le journal du serveur. Cette erreur peut se produire si les mêmes données ont été insérées plus d'une fois.
-
-Ainsi, l'effondrement ne devrait pas changer les résultats du calcul des statistiques.
-Les changements se sont progressivement effondrés de sorte qu'à la fin seul le dernier état de presque tous les objets à gauche.
-
-Le `Sign` est nécessaire car l'algorithme de fusion ne garantit pas que toutes les lignes avec la même clé de tri seront dans la même partie de données résultante et même sur le même serveur physique. Processus de ClickHouse `SELECT` les requêtes avec plusieurs threads, et il ne peut pas prédire l'ordre des lignes dans le résultat. L'agrégation est nécessaire s'il y a un besoin d'obtenir complètement “collapsed” les données de `CollapsingMergeTree` table.
-
-Pour finaliser la réduction, écrivez une requête avec `GROUP BY` fonctions de clause et d'agrégation qui tiennent compte du signe. Par exemple, pour calculer la quantité, l'utilisation `sum(Sign)` plutôt `count()`. Pour calculer la somme de quelque chose, utilisez `sum(Sign * x)` plutôt `sum(x)` et ainsi de suite , et également ajouter `HAVING sum(Sign) > 0`.
-
-Aggregate `count`, `sum` et `avg` pourrait être calculée de cette manière. Aggregate `uniq` peut être calculé si un objet a au moins un état non réduit. Aggregate `min` et `max` impossible de calculer parce que `CollapsingMergeTree` n'enregistre pas l'historique des valeurs des États réduits.
-
-Si vous avez besoin d'extraire des données sans agrégation (par exemple, pour vérifier si des lignes sont présentes dont les valeurs les plus récentes correspondent à certaines conditions), vous pouvez utiliser `FINAL` le modificateur du `FROM` clause. Cette approche est nettement moins efficace.
-
-## Exemple D'utilisation {#example-of-use}

-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Création de la table:
-
-``` sql
-CREATE TABLE UAct
-(
-    UserID UInt64,
-    PageViews UInt8,
-    Duration UInt8,
-    Sign Int8
-)
-ENGINE = CollapsingMergeTree(Sign)
-ORDER BY UserID
-```
-
-Insertion des données:
-
-``` sql
-INSERT INTO UAct VALUES (4324182021466249494, 5, 146, 1)
-```
-
-``` sql
-INSERT INTO UAct VALUES (4324182021466249494, 5, 146, -1),(4324182021466249494, 6, 185, 1)
-```
-
-Nous utilisons deux `INSERT` requêtes pour créer deux parties de données différentes. Si nous insérons les données avec une requête, ClickHouse crée une partie de données et n'effectuera aucune fusion.
-
-L'obtention de données:
-
-``` sql
-SELECT * FROM UAct
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Que voyons-nous et où s'effondre?
-
-Avec deux `INSERT` requêtes, nous avons créé 2 parties de données. Le `SELECT` la requête a été effectuée dans 2 threads, et nous avons obtenu un ordre aléatoire de lignes. L'effondrement n'a pas eu lieu car il n'y avait pas encore de fusion des parties de données. ClickHouse fusionne une partie des données dans un moment inconnu que nous ne pouvons pas prédire.
-
-Nous avons donc besoin d'agrégation:
-
-``` sql
-SELECT
-    UserID,
-    sum(PageViews * Sign) AS PageViews,
-    sum(Duration * Sign) AS Duration
-FROM UAct
-GROUP BY UserID
-HAVING sum(Sign) > 0
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┐
-│ 4324182021466249494 │         6 │      185 │
-└─────────────────────┴───────────┴──────────┘
-```
-
-Si nous n'avons pas besoin d'agrégation et de vouloir forcer l'effondrement, nous pouvons utiliser `FINAL` le modificateur `FROM` clause.
-
-``` sql
-SELECT * FROM UAct FINAL
-```
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Cette façon de sélectionner les données est très inefficace. Ne l'utilisez pas pour les grandes tables.
-
-## Exemple D'une autre approche {#example-of-another-approach}
-
-Les données de l'exemple:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │    1 │
-│ 4324182021466249494 │        -5 │     -146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-L'idée est que les fusions ne prennent en compte que les champs clés. Et dans le “Cancel” ligne nous pouvons spécifier des valeurs négatives qui égalisent la version précédente de la ligne lors de la sommation sans utiliser la colonne de signe. Pour cette approche, il est nécessaire de changer le type de données `PageViews`,`Duration` pour stocker les valeurs négatives de UInt8 - \> Int16.
-
-``` sql
-CREATE TABLE UAct
-(
-    UserID UInt64,
-    PageViews Int16,
-    Duration Int16,
-    Sign Int8
-)
-ENGINE = CollapsingMergeTree(Sign)
-ORDER BY UserID
-```
-
-Nous allons tester l'approche:
-
-``` sql
-insert into UAct values(4324182021466249494,  5,  146,  1);
-insert into UAct values(4324182021466249494, -5, -146, -1);
-insert into UAct values(4324182021466249494,  6,  185,  1);
-
-select * from UAct final; // avoid using final in production (just for a test or small tables)

----
-
-# Clé De Partitionnement Personnalisée {#custom-partitioning-key}
-
-Le partitionnement est disponible pour [MergeTree](mergetree.md) table de famille (y compris les [répliqué](replication.md) table). [Les vues matérialisées](../special/materializedview.md#materializedview) basé sur les tables MergeTree prennent également en charge le partitionnement.
-
-Une partition est une combinaison logique d'enregistrements dans une table selon un critère spécifié. Vous pouvez définir une partition par un critère arbitraire, comme, par mois, par jour, ou par type d'événement. Chaque partition est stockée séparément pour simplifier les manipulations de ces données. Lors de l'accès aux données, ClickHouse utilise le plus petit sous-ensemble de partitions possible.
-
-La partition est spécifiée dans le `PARTITION BY expr` clause lors de [création d'une table](mergetree.md#table_engine-mergetree-creating-a-table). La clé de partition peut être n'importe quelle expression des colonnes de la table. Par exemple, pour spécifier le partitionnement par mois, utilisez l'expression `toYYYYMM(date_column)`:
-
-``` sql
-CREATE TABLE visits
-(
-    VisitDate Date,
-    Hour UInt8,
-    ClientID UUID
-)
-ENGINE = MergeTree()
-PARTITION BY toYYYYMM(VisitDate)
-ORDER BY Hour;
-```
-
-La clé de partition peut également être un tuple d'expressions (similaire à la [clé primaire](mergetree.md#primary-keys-and-indexes-in-queries)). Exemple:
-
-``` sql
-ENGINE = ReplicatedCollapsingMergeTree('/clickhouse/tables/name', 'replica1', Sign)
-PARTITION BY (toMonday(StartDate), EventType)
-ORDER BY (CounterID, StartDate, intHash32(UserID));
-```
-
-Dans cet exemple, nous définissons le partitionnement par les types d'événements qui se sont produits au cours de la semaine en cours.
-
-Lors de l'insertion de nouvelles données dans une table, ces données sont stockées en tant que partie séparée (bloc) triée par la clé primaire. Dans 10-15 minutes après l'insertion, les parties de la même partition sont fusionnées dans la partie entière.
-
-!!! info "Info"
-    Une fusion ne fonctionne que pour les parties de données qui ont la même valeur pour l'expression de partitionnement. Cela signifie **vous ne devriez pas faire des partitions trop granulaires** (plus d'un millier de partitions). Sinon, l' `SELECT` la requête fonctionne mal en raison d'un nombre déraisonnablement élevé de fichiers dans le système de fichiers et des descripteurs de fichiers ouverts.
-
-L'utilisation de la [système.partie](../../../operations/system-tables.md#system_tables-parts) table pour afficher les parties et les partitions de la table. Par exemple, supposons que nous avons une `visits` table avec partitionnement par mois. Nous allons effectuer le `SELECT` la requête pour l' `system.parts` table:
-
-``` sql
-SELECT
-    partition,
-    name,
-    active
-FROM system.parts
-WHERE table = 'visits'
-```

-
-Le `partition` colonne contient les noms des partitions. Il y a deux partitions dans cet exemple: `201901` et `201902`. Vous pouvez utiliser cette valeur de colonne pour spécifier le nom de [ALTER … PARTITION](#alter_manipulations-with-partitions) requête.
-
-Le `name` colonne contient les noms des parties de données de partition. Vous pouvez utiliser cette colonne pour spécifier le nom de la partie dans la [ALTER ATTACH PART](#alter_attach-partition) requête.
-
-Décomposons le nom de la première partie: `201901_1_3_1`:
-
--   `201901` est le nom de la partition.
--   `1` est le nombre minimum du bloc de données.
--   `3` est le nombre maximal de blocs de données.
--   `1` est le niveau de bloc (la profondeur de l'arbre de fusion à partir duquel il est formé).
-
-!!! info "Info"
-    Les parties des tables de type ancien ont le nom: `20190117_20190123_2_2_0` (date minimale - date maximale - numéro de bloc minimum - numéro de bloc maximum-niveau).
-
-Le `active` colonne indique le statut de la partie. `1` est active; `0` est inactif. Les parties inactives sont, par exemple, des parties source restant après la fusion à une partie plus grande. Les parties de données corrompues sont également indiquées comme inactives.
-
-Comme vous pouvez le voir dans l'exemple, il y a plusieurs parties séparées de la même partition (par exemple, `201901_1_3_1` et `201901_1_9_2`). Cela signifie que ces parties ne sont pas encore fusionnées. Clickhouse fusionne les parties insérées des données périodiquement, environ 15 minutes après l'insertion. En outre, vous pouvez effectuer une fusion non planifiée en utilisant [OPTIMIZE](../../../sql-reference/statements/misc.md#misc_operations-optimize) requête. Exemple:
-
-``` sql
-OPTIMIZE TABLE visits PARTITION 201902;
-```
-
-``` text
-┌─partition─┬─name───────────┬─active─┐
-│ 201901    │ 201901_1_3_1   │      0 │
-│ 201901    │ 201901_1_9_2   │      1 │
-│ 201901    │ 201901_8_8_0   │      0 │
-│ 201901    │ 201901_9_9_0   │      0 │
-│ 201902    │ 201902_4_6_1   │      0 │
-│ 201902    │ 201902_4_11_2  │      1 │
-│ 201902    │ 201902_10_10_0 │      0 │
-│ 201902    │ 201902_11_11_0 │      0 │
-└───────────┴────────────────┴────────┘
-```
-
-Les parties inactives seront supprimées environ 10 minutes après la fusion.
-
-Une autre façon d'afficher un ensemble de pièces et de partitions est d'aller dans le répertoire de la table: `/var/lib/clickhouse/data/<database>/<table>/`. Exemple:
-
-``` bash
-/var/lib/clickhouse/data/default/visits$ ls -l
-total 40
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  1 16:48 201901_1_3_1
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:17 201901_1_9_2
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 15:52 201901_8_8_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 15:52 201901_9_9_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:17 201902_10_10_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:17 201902_11_11_0
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 16:19 201902_4_11_2
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  5 12:09 201902_4_6_1
-drwxr-xr-x 2 clickhouse clickhouse 4096 Feb  1 16:48 detached
-```
-
-Dossier ‘201901_1_1_0’, ‘201901_1_7_1’ et ainsi de suite sont les répertoires des parties. Chaque partie se rapporte à une partition correspondante et contient des données juste pour un certain mois (la table dans cet exemple a partitionnement par mois).
-
-Le `detached` le répertoire contient des parties qui ont été détachées de la table à l'aide [DETACH](../../../sql-reference/statements/alter.md#alter_detach-partition) requête. Les parties corrompues sont également déplacées dans ce répertoire, au lieu d'être supprimées. Le serveur n'utilise pas les pièces de la `detached` directory. You can add, delete, or modify the data in this directory at any time – the server will not know about this until you run the [ATTACH](../../../sql-reference/statements/alter.md#alter_attach-partition) requête.
-
-Notez que sur le serveur d'exploitation, vous ne pouvez pas modifier manuellement l'ensemble de pièces ou leurs données sur le système de fichiers, car le serveur ne le saura pas. Pour les tables non répliquées, vous pouvez le faire lorsque le serveur est arrêté, mais ce n'est pas recommandé. Pour les tables répliquées, l'ensemble de pièces ne peut en aucun cas être modifié.
-
-ClickHouse vous permet d'effectuer des opérations avec les partitions: les supprimer, copier d'une table à une autre, ou créer une sauvegarde. Voir la liste de toutes les opérations de la section [Manipulations avec des Partitions et des pièces](../../../sql-reference/statements/alter.md#alter_manipulations-with-partitions).

-# GraphiteMergeTree {#graphitemergetree}
-
-Ce moteur est conçu pour l'amincissement et l'agrégation / moyenne (cumul) [Graphite](http://graphite.readthedocs.io/en/latest/index.html) données. Il peut être utile aux développeurs qui veulent utiliser ClickHouse comme un magasin de données pour Graphite.
-
-Vous pouvez utiliser N'importe quel moteur de table ClickHouse pour stocker les données Graphite si vous n'avez pas besoin de cumul, mais si vous avez besoin d'un cumul, utilisez `GraphiteMergeTree`. Le moteur réduit le volume de stockage et augmente l'efficacité des requêtes de Graphite.
-
-Le moteur hérite des propriétés de [MergeTree](mergetree.md).
-
-## Création d'une Table {#creating-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    Path String,
-    Time DateTime,
-    Value <Numeric_type>,
-    Version <Numeric_type>
-    ...
-) ENGINE = GraphiteMergeTree(config_section)
-[PARTITION BY expr]
-[ORDER BY expr]
-[SAMPLE BY expr]
-[SETTINGS name=value, ...]
-```
-
-Voir une description détaillée de la [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) requête.
-
-Un tableau pour les données de Graphite devrait avoir les colonnes suivantes pour les données suivantes:
-
--   Nom métrique (Capteur De Graphite). Type de données: `String`.
-
--   Temps de mesure de la métrique. Type de données: `DateTime`.
-
--   La valeur de la métrique. Type de données: tout numérique.
-
--   La Version de la métrique. Type de données: tout numérique.
-
-    ClickHouse enregistre les lignes avec la version la plus élevée ou la dernière écrite si les versions sont les mêmes. Les autres lignes sont supprimées lors de la fusion des parties de données.
-
-Les noms de ces colonnes doivent être définis dans la configuration de cumul.
-
-**GraphiteMergeTree paramètres**
-
--   `config_section` — Name of the section in the configuration file, where are the rules of rollup set.
-
-**Les clauses de requête**
-
-Lors de la création d'un `GraphiteMergeTree` de table, de la même [clause](mergetree.md#table_engine-mergetree-creating-a-table) sont nécessaires, comme lors de la création d'un `MergeTree` table.

-## Configuration De Cumul {#rollup-configuration}
-
-Les paramètres de cumul sont définis par [graphite_rollup](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-graphite) paramètre dans la configuration du serveur. Le nom du paramètre pourrait être tout. Vous pouvez créer plusieurs configurations et les utiliser pour différentes tables.
-
-Structure de configuration de cumul:
-
-      required-columns
-      patterns
-
-### Les Colonnes Requises {#required-columns}
-
--   `path_column_name` — The name of the column storing the metric name (Graphite sensor). Default value: `Path`.
--   `time_column_name` — The name of the column storing the time of measuring the metric. Default value: `Time`.
--   `value_column_name` — The name of the column storing the value of the metric at the time set in `time_column_name`. Valeur par défaut: `Value`.
--   `version_column_name` — The name of the column storing the version of the metric. Default value: `Timestamp`.

-
-!!! warning "Attention"
-    Les motifs doivent être strictement commandés:
-
-      1. Patterns without `function` or `retention`.
-      1. Patterns with both `function` and `retention`.
-      1. Pattern `default`.
-
-Lors du traitement d'une ligne, ClickHouse vérifie les règles `pattern` section. Chacun `pattern` (comprendre `default`) les articles peuvent contenir des `function` paramètre d'agrégation, `retention` les paramètres ou les deux à la fois. Si le nom de la métrique correspond `regexp` les règles de la `pattern` section (ou sections) sont appliquées; sinon, les règles de la `default` section sont utilisés.
-
-Champs pour `pattern` et `default` section:
-
--   `regexp`– A pattern for the metric name.
--   `age` – The minimum age of the data in seconds.
--   `precision`– How precisely to define the age of the data in seconds. Should be a divisor for 86400 (seconds in a day).
--   `function` – The name of the aggregating function to apply to data whose age falls within the range `[age, age + precision]`.

-# MergeTree {#table_engines-mergetree}
-
-Le `MergeTree` moteur et autres moteurs de cette famille (`*MergeTree`) sont les moteurs de table ClickHouse les plus robustes.
-
-Les moteurs de la `MergeTree` famille sont conçus pour l'insertion d'une très grande quantité de données dans une table. Les données sont rapidement écrites dans la table partie par partie, puis des règles sont appliquées pour fusionner les parties en arrière-plan. Cette méthode est beaucoup plus efficace que de réécrire continuellement les données dans le stockage pendant l'insertion.
-
-Principales caractéristiques:
-
--   Stocke les données triées par clé primaire.
-
-    Cela vous permet de créer un petit index clairsemé qui aide à trouver les données plus rapidement.
-
--   Les Partitions peuvent être utilisées si [clé de partitionnement](custom-partitioning-key.md) est spécifié.
-
-    ClickHouse prend en charge certaines opérations avec des partitions plus efficaces que les opérations générales sur les mêmes données avec le même résultat. ClickHouse Coupe également automatiquement les données de partition où la clé de partitionnement est spécifiée dans la requête. Cela améliore également les performances de la requête.
-
--   Prise en charge de la réplication des données.
-
-    La famille de `ReplicatedMergeTree` tables fournit la réplication des données. Pour plus d'informations, voir [Réplication des données](replication.md).
-
--   Appui d'échantillonnage de données.
-
-    Si nécessaire, vous pouvez définir la méthode d'échantillonnage des données dans le tableau.
-
-!!! info "Info"
-    Le [Fusionner](../special/merge.md#merge) le moteur n'appartient pas à la `*MergeTree` famille.
-
-## Création d'une Table {#table_engine-mergetree-creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
-    ...

-[ORDER BY expr]
-[PRIMARY KEY expr]
-[SAMPLE BY expr]
-[TTL expr [DELETE|TO DISK 'xxx'|TO VOLUME 'xxx'], ...]
-[SETTINGS name=value, ...]
-```
-
-Pour une description des paramètres, voir [Créer une description de requête](../../../sql-reference/statements/create.md).
-
-!!! note "Note"
-    `INDEX` est une fonctionnalité expérimentale, voir [Index De Saut De Données](#table_engine-mergetree-data_skipping-indexes).
-
-### Les Clauses De Requête {#mergetree-query-clauses}
-
--   `ENGINE` — Name and parameters of the engine. `ENGINE = MergeTree()`. Le `MergeTree` le moteur n'a pas de paramètres.
-
--   `PARTITION BY` — The [clé de partitionnement](custom-partitioning-key.md).
-
-    Pour le partitionnement par mois, utilisez les `toYYYYMM(date_column)` l'expression, où `date_column` est une colonne avec une date du type [Date](../../../sql-reference/data-types/date.md). Les noms de partition ici ont le `"YYYYMM"` format.
-
--   `ORDER BY` — The sorting key.
-
-    Un tuple de colonnes ou d'expressions arbitraires. Exemple: `ORDER BY (CounterID, EventDate)`.
-
--   `PRIMARY KEY` — The primary key if it [diffère de la clé de tri](#choosing-a-primary-key-that-differs-from-the-sorting-key).
-
-    Par défaut, la clé primaire est la même que la clé de tri (qui est spécifiée par `ORDER BY` clause). Ainsi dans la plupart des cas il n'est pas nécessaire de spécifier un `PRIMARY KEY` clause.
-
--   `SAMPLE BY` — An expression for sampling.
-
-    Si un échantillonnage expression est utilisée, la clé primaire doit contenir. Exemple: `SAMPLE BY intHash32(UserID) ORDER BY (CounterID, EventDate, intHash32(UserID))`.
-
--   `TTL` — A list of rules specifying storage duration of rows and defining logic of automatic parts movement [entre disques et volumes](#table_engine-mergetree-multiple-volumes).
-
-    L'Expression doit en avoir une `Date` ou `DateTime` colonne comme un résultat. Exemple:
-    `TTL date + INTERVAL 1 DAY`
-
-    Le Type de la règle `DELETE|TO DISK 'xxx'|TO VOLUME 'xxx'` spécifie une action à effectuer avec la partie si l'expression est satisfaite (atteint l'heure actuelle): suppression des Lignes expirées, déplacement d'une partie (si l'expression est satisfaite pour toutes les lignes d'une partie) sur le disque spécifié (`TO DISK 'xxx'`) ou de volume (`TO VOLUME 'xxx'`). Le type par défaut de la règle est suppression (`DELETE`). Liste de règles multiples peut spécifié, mais il ne devrait pas y avoir plus d'un `DELETE` règle.
-
-    Pour plus de détails, voir [TTL pour les colonnes et les tableaux](#table_engine-mergetree-ttl)
-
--   `SETTINGS` — Additional parameters that control the behavior of the `MergeTree`:
-
-    -   `index_granularity` — Maximum number of data rows between the marks of an index. Default value: 8192. See [Le Stockage De Données](#mergetree-data-storage).
-    -   `index_granularity_bytes` — Maximum size of data granules in bytes. Default value: 10Mb. To restrict the granule size only by number of rows, set to 0 (not recommended). See [Le Stockage De Données](#mergetree-data-storage).
-    -   `enable_mixed_granularity_parts` — Enables or disables transitioning to control the granule size with the `index_granularity_bytes` paramètre. Avant la version 19.11, il n'y avait que le `index_granularity` réglage pour restreindre la taille des granules. Le `index_granularity_bytes` le paramètre améliore les performances de ClickHouse lors de la sélection de données à partir de tables avec de grandes lignes (des dizaines et des centaines de mégaoctets). Si vous avez des tables avec de grandes lignes, vous pouvez activer ce paramètre pour les tables d'améliorer l'efficacité de `SELECT` requête.
-    -   `use_minimalistic_part_header_in_zookeeper` — Storage method of the data parts headers in ZooKeeper. If `use_minimalistic_part_header_in_zookeeper=1`, puis Zookeeper stocke moins de données. Pour plus d'informations, voir le [Description du réglage](../../../operations/server-configuration-parameters/settings.md#server-settings-use_minimalistic_part_header_in_zookeeper) dans “Server configuration parameters”.
-    -   `min_merge_bytes_to_use_direct_io` — The minimum data volume for merge operation that is required for using direct I/O access to the storage disk. When merging data parts, ClickHouse calculates the total storage volume of all the data to be merged. If the volume exceeds `min_merge_bytes_to_use_direct_io` octets, ClickHouse lit et écrit les données sur le disque de stockage en utilisant l'interface d'E/S directe (`O_DIRECT` option). Si `min_merge_bytes_to_use_direct_io = 0`, puis les e/s directes sont désactivées. Valeur par défaut: `10 * 1024 * 1024 * 1024` octet.
-        <a name="mergetree_setting-merge_with_ttl_timeout"></a>
-    -   `merge_with_ttl_timeout` — Minimum delay in seconds before repeating a merge with TTL. Default value: 86400 (1 day).
-    -   `write_final_mark` — Enables or disables writing the final index mark at the end of data part (after the last byte). Default value: 1. Don't turn it off.
-    -   `merge_max_block_size` — Maximum number of rows in block for merge operations. Default value: 8192.
-    -   `storage_policy` — Storage policy. See [Utilisation de plusieurs périphériques de bloc pour le stockage de données](#table_engine-mergetree-multiple-volumes).
-
-**Exemple de réglage des Sections**
-
-``` sql
-ENGINE MergeTree() PARTITION BY toYYYYMM(EventDate) ORDER BY (CounterID, EventDate, intHash32(UserID)) SAMPLE BY intHash32(UserID) SETTINGS index_granularity=8192
-```
-
-Dans l'exemple, nous définissons le partitionnement par mois.
-
-Nous définissons également une expression pour l'échantillonnage en tant que hachage par l'ID utilisateur. Cela vous permet de pseudorandomiser les données dans la table pour chaque `CounterID` et `EventDate`. Si vous définissez un [SAMPLE](../../../sql-reference/statements/select/sample.md#select-sample-clause) clause lors de la sélection des données, ClickHouse retournera un échantillon de données uniformément pseudo-aléatoire pour un sous-ensemble d'utilisateurs.
-
-Le `index_granularity` paramètre peut être omis, car 8192 est la valeur par défaut.

-```
-
-**Paramètres MergeTree ()**
-
--   `date-column` — The name of a column of the [Date](../../../sql-reference/data-types/date.md) type. ClickHouse crée automatiquement des partitions par mois en fonction de cette colonne. Les noms de partition sont dans le `"YYYYMM"` format.
--   `sampling_expression` — An expression for sampling.
--   `(primary, key)` — Primary key. Type: [Tuple()](../../../sql-reference/data-types/tuple.md)
--   `index_granularity` — The granularity of an index. The number of data rows between the “marks” d'un index. La valeur 8192 est appropriée pour la plupart des tâches.
-
-**Exemple**
-
-``` sql
-MergeTree(EventDate, intHash32(UserID), (CounterID, EventDate, intHash32(UserID)), 8192)
-```
-
-Le `MergeTree` le moteur est configuré de la même manière que dans l'exemple ci-dessus pour la méthode de configuration du moteur principal.
-</details>
-
-## Le Stockage De Données {#mergetree-data-storage}
-
-Une table se compose de parties de données triées par clé primaire.
-
-Lorsque des données sont insérées dans une table, des parties de données distinctes sont créées et chacune d'elles est lexicographiquement triée par clé primaire. Par exemple, si la clé primaire est `(CounterID, Date)`, les données de la pièce sont triées par `CounterID` et au sein de chaque `CounterID` il est commandé par `Date`.
-
-Les données appartenant à différentes partitions sont séparés en différentes parties. En arrière-plan, ClickHouse fusionne des parties de données pour un stockage plus efficace. Les parties appartenant à des partitions différentes ne sont pas fusionnées. La fusion mécanisme ne garantit pas que toutes les lignes avec la même clé primaire sera dans la même partie des données.
-
-Chaque partie de données est logiquement divisée en granules. Un granule est le plus petit ensemble de données indivisible que ClickHouse lit lors de la sélection des données. ClickHouse ne divise pas les lignes ou les valeurs, de sorte que chaque granule contient toujours un nombre entier de lignes. La première rangée de granules est marqué avec la valeur de la clé primaire de la ligne. Pour chaque partie de données, ClickHouse crée un fichier d'index qui stocke les marques. Pour chaque colonne, que ce soit dans la clé primaire ou non, ClickHouse stocke également les mêmes marques. Ces marques vous permettent de trouver des données directement dans les fichiers de colonnes.
-
-La taille de granule est limitée par `index_granularity` et `index_granularity_bytes` paramètres du moteur de table. Le nombre de lignes dans un granule jette dans la `[1, index_granularity]` gamme, en fonction de la taille des lignes. La taille des granulés peut dépasser `index_granularity_bytes` si la taille d'une seule ligne est supérieure à la valeur du paramètre. Dans ce cas, la taille du granule est égale à la taille de la ligne.
-
-## Clés primaires et Index dans les requêtes {#primary-keys-and-indexes-in-queries}
-
-Prendre la `(CounterID, Date)` clé primaire comme un exemple. Dans ce cas, le tri et l'index peuvent être illustrés comme suit:
-
-      Whole data:     [---------------------------------------------]
-      CounterID:      [aaaaaaaaaaaaaaaaaabbbbcdeeeeeeeeeeeeefgggggggghhhhhhhhhiiiiiiiiikllllllll]
-      Date:           [1111111222222233331233211111222222333211111112122222223111112223311122333]
-      Marks:           |      |      |      |      |      |      |      |      |      |      |
-                      a,1    a,2    a,3    b,3    e,2    e,3    g,1    h,2    i,1    i,3    l,3
-      Marks numbers:   0      1      2      3      4      5      6      7      8      9      10
-
-Si la requête de données spécifie:
-
--   `CounterID in ('a', 'h')` le serveur lit les données dans les gammes des marques `[0, 3)` et `[6, 8)`.
--   `CounterID IN ('a', 'h') AND Date = 3` le serveur lit les données dans les gammes des marques `[1, 3)` et `[7, 8)`.
--   `Date = 3`, le serveur lit les données de la plage de marque `[1, 10]`.
-
-Les exemples ci-dessus montrent qu'il est toujours plus efficace d'utiliser un indice qu'une analyse complète.
-
-Un index clairsemé permet de lire des données supplémentaires. Lors de la lecture d'une plage unique de la clé primaire, jusqu'à `index_granularity * 2` lignes supplémentaires dans chaque bloc de données peut être lu.
-
-Les index clairsemés vous permettent de travailler avec un très grand nombre de lignes de table, car dans la plupart des cas, ces index tiennent dans la RAM de l'ordinateur.
-
-ClickHouse ne nécessite pas de clé primaire unique. Vous pouvez insérer plusieurs lignes avec la même clé primaire.
-
-### Sélection de la clé primaire {#selecting-the-primary-key}
-
-Le nombre de colonnes de la clé primaire n'est pas explicitement limitée. Selon la structure de données, vous pouvez inclure plus ou moins de colonnes dans la clé primaire. Cela peut:
-
--   Améliorer la performance d'un indice.
-
-    Si la clé primaire est `(a, b)`, puis ajouter une autre colonne `c` pour améliorer les performances si les conditions suivantes sont réunies:
-
-    -   Il y a des requêtes avec une condition sur la colonne `c`.
-    -   Longues plages de données (plusieurs fois plus longues que `index_granularity`) avec des valeurs identiques pour `(a, b)` sont communs. En d'autres termes, lors de l'ajout d'une autre colonne vous permet de passer très longues plages de données.
-
--   Améliorer la compression des données.
-
-    ClickHouse trie les données par clé primaire, donc plus la cohérence est élevée, meilleure est la compression.
-
--   Fournir une logique supplémentaire lors de la fusion de parties de [CollapsingMergeTree](collapsingmergetree.md#table_engine-collapsingmergetree) et [SummingMergeTree](summingmergetree.md) moteur.
-
-    Dans ce cas, on peut spécifier l' *clé de tri* qui est différente de la clé primaire.
-
-Une clé primaire longue affectera négativement les performances d'insertion et la consommation de mémoire, mais des colonnes supplémentaires dans la clé primaire n'affecteront pas les performances de ClickHouse pendant `SELECT` requête.
-
-### Choisir une clé primaire qui diffère de la clé de tri {#choosing-a-primary-key-that-differs-from-the-sorting-key}
-
-Il est possible de spécifier une clé primaire (une expression avec des valeurs qui sont écrites dans le fichier d'index pour chaque marque) qui est différente de la clé de tri (une expression pour trier les lignes dans les parties de données). Dans ce cas, le tuple d'expression de clé primaire doit être un préfixe du tuple d'expression de clé de tri.
-
-Cette fonctionnalité est utile lorsque vous utilisez le [SummingMergeTree](summingmergetree.md) et
-[AggregatingMergeTree](aggregatingmergetree.md) table des moteurs. Dans un cas courant lors de l'utilisation de ces moteurs, la table a deux types de colonnes: *dimension* et *mesure*. Les requêtes typiques agrégent les valeurs des colonnes de mesure avec arbitraire `GROUP BY` et filtrage par dimensions. Comme SummingMergeTree et AggregatingMergeTree regroupent des lignes avec la même valeur de la clé de tri, il est naturel d'y ajouter toutes les dimensions. En conséquence, l'expression se compose d'une longue liste de colonnes, et cette liste doit être mise à jour fréquemment avec nouvellement ajoutée.
-
-Dans ce cas, il est logique de ne laisser que quelques colonnes dans la clé primaire qui fourniront des analyses de plage efficaces et ajouteront les colonnes de dimension restantes au tuple de clé de tri.
-
-[ALTER](../../../sql-reference/statements/alter.md) la clé de tri est une opération légère car lorsqu'une nouvelle colonne est ajoutée simultanément à la table et à la clé de tri, les parties de données existantes n'ont pas besoin d'être modifiées. Comme l'ancienne clé de tri est un préfixe de la nouvelle clé de tri et qu'il n'y a pas de données dans la colonne nouvellement ajoutée, les données sont triées à la fois par l'ancienne et la nouvelle clé de tri au moment de la modification de la table.
-
-### Utilisation D'Index et de Partitions dans les requêtes {#use-of-indexes-and-partitions-in-queries}
-
-Pour `SELECT` requêtes, clickhouse analyse si un index peut être utilisé. Un index peut être utilisé si le `WHERE/PREWHERE` clause a une expression (comme l'un des éléments de conjonction, ou entièrement) qui représente une opération de comparaison d'égalité ou d'inégalité, ou si elle a `IN` ou `LIKE` avec un préfixe fixe sur les colonnes ou les expressions qui sont dans la clé primaire ou la clé de partitionnement, ou sur certaines fonctions partiellement répétitives de ces colonnes, ou les relations logiques de ces expressions.
-
-Ainsi, il est possible d'exécuter des requêtes sur une ou plusieurs plages de la clé primaire. Dans cet exemple, les requêtes seront rapides lorsqu'elles sont exécutées pour une balise de suivi spécifique, pour une balise et une plage de dates spécifiques, pour une balise et une date spécifiques, pour plusieurs balises avec une plage de dates, etc.
-
-Regardons le moteur configuré comme suit:
-
-      ENGINE MergeTree() PARTITION BY toYYYYMM(EventDate) ORDER BY (CounterID, EventDate) SETTINGS index_granularity=8192
-
-Dans ce cas, dans les requêtes:
-
-``` sql
-SELECT count() FROM table WHERE EventDate = toDate(now()) AND CounterID = 34
-SELECT count() FROM table WHERE EventDate = toDate(now()) AND (CounterID = 34 OR CounterID = 42)
-SELECT count() FROM table WHERE ((EventDate >= toDate('2014-01-01') AND EventDate <= toDate('2014-01-31')) OR EventDate = toDate('2014-05-01')) AND CounterID IN (101500, 731962, 160656) AND (CounterID = 101500 OR EventDate != toDate('2014-05-01'))
-```
-
-ClickHouse utilisera l'index de clé primaire pour supprimer les données incorrectes et la clé de partitionnement mensuel pour supprimer les partitions qui se trouvent dans des plages de dates incorrectes.
-
-Les requêtes ci-dessus montrent que l'index est utilisé même pour les expressions complexes. La lecture de la table est organisée de sorte que l'utilisation de l'index ne peut pas être plus lente qu'une analyse complète.
-
-Dans l'exemple ci-dessous, l'index ne peut pas être utilisé.
-
-``` sql
-SELECT count() FROM table WHERE CounterID = 34 OR URL LIKE '%upyachka%'
-```
-
-Pour vérifier si ClickHouse pouvez utiliser l'index lors de l'exécution d'une requête, utilisez les paramètres [force_index_by_date](../../../operations/settings/settings.md#settings-force_index_by_date) et [force_primary_key](../../../operations/settings/settings.md).
-
-La clé de partitionnement par mois permet de lire uniquement les blocs de données qui contiennent des dates de la plage appropriée. Dans ce cas, le bloc de données peut contenir des données pour plusieurs dates (jusqu'à un mois entier). Dans un bloc, les données sont triées par clé primaire, qui peut ne pas contenir la date comme première colonne. Pour cette raison, l'utilisation d'une requête avec seulement une condition de date qui ne spécifie pas le préfixe de clé primaire entraînera la lecture de plus de données que pour une seule date.
-
-### Utilisation de L'Index pour les clés primaires partiellement monotones {#use-of-index-for-partially-monotonic-primary-keys}
-
-Considérons, par exemple, les jours du mois. Ils forment un [monotone de la séquence](https://en.wikipedia.org/wiki/Monotonic_function) pendant un mois, mais pas monotone pendant des périodes plus longues. C'est une séquence partiellement monotone. Si un utilisateur crée la table avec une clé primaire partiellement monotone, ClickHouse crée un index clairsemé comme d'habitude. Lorsqu'un utilisateur sélectionne des données à partir de ce type de table, ClickHouse analyse les conditions de requête. Si L'utilisateur veut obtenir des données entre deux marques de l'index et que ces deux marques tombent dans un mois, ClickHouse peut utiliser l'index dans ce cas particulier car il peut calculer la distance entre les paramètres d'une requête et les marques d'index.
-
-ClickHouse ne peut pas utiliser un index si les valeurs de la clé primaire dans la plage de paramètres de requête ne représentent pas une séquence monotone. Dans ce cas, ClickHouse utilise la méthode full scan.
-
-ClickHouse utilise cette logique non seulement pour les séquences de jours du mois, mais pour toute clé primaire qui représente une séquence partiellement monotone.
-
-### Index de saut de données (expérimental) {#table_engine-mergetree-data_skipping-indexes}
-
-La déclaration d'index se trouve dans la section colonnes du `CREATE` requête.
-
-``` sql
-INDEX index_name expr TYPE type(...) GRANULARITY granularity_value
-```
-
-Pour les tables de la `*MergeTree` famille, les indices de saut de données peuvent être spécifiés.
-
-Ces indices agrégent certaines informations sur l'expression spécifiée sur les blocs, qui consistent en `granularity_value` granules (la taille du granule est spécifiée en utilisant `index_granularity` réglage dans le moteur de table). Ensuite, ces agrégats sont utilisés dans `SELECT` requêtes pour réduire la quantité de données à lire à partir du disque en ignorant de gros blocs de données `where` la requête ne peut pas être satisfait.
-
-**Exemple**
-
-``` sql
-CREATE TABLE table_name
-(
-    u64 UInt64,
-    i32 Int32,
-    s String,
-    ...
-    INDEX a (u64 * i32, s) TYPE minmax GRANULARITY 3,
-    INDEX b (u64 * length(s)) TYPE set(1000) GRANULARITY 4
-) ENGINE = MergeTree()
-...
-```
-
-Les Indices de L'exemple peuvent être utilisés par ClickHouse pour réduire la quantité de données à lire à partir du disque dans les requêtes suivantes:
-
-``` sql
-SELECT count() FROM table WHERE s < 'z'
-SELECT count() FROM table WHERE u64 * i32 == 10 AND u64 * length(s) >= 1234
-```
-
-#### Types d'Indices disponibles {#available-types-of-indices}
-
--   `minmax`
-
-    Magasins extrêmes de l'expression spécifiée (si l'expression est `tuple` puis il stocke les extrêmes pour chaque élément de `tuple`), utilise les informations stockées pour sauter des blocs de données comme la clé primaire.
-
--   `set(max_rows)`
-
-    Stocke les valeurs uniques de l'expression spécifiée (pas plus de `max_rows` rangée, `max_rows=0` moyen “no limits”). Utilise les valeurs pour vérifier si le `WHERE` l'expression n'est pas satisfiable sur un bloc de données.
-
--   `ngrambf_v1(n, size_of_bloom_filter_in_bytes, number_of_hash_functions, random_seed)`
-
-    Magasins un [Filtre de Bloom](https://en.wikipedia.org/wiki/Bloom_filter) qui contient tous les ngrams d'un bloc de données. Fonctionne uniquement avec des chaînes. Peut être utilisé pour l'optimisation de `equals`, `like` et `in` expression.
-
-    -   `n` — ngram size,
-    -   `size_of_bloom_filter_in_bytes` — Bloom filter size in bytes (you can use large values here, for example, 256 or 512, because it can be compressed well).
-    -   `number_of_hash_functions` — The number of hash functions used in the Bloom filter.
-    -   `random_seed` — The seed for Bloom filter hash functions.
-
--   `tokenbf_v1(size_of_bloom_filter_in_bytes, number_of_hash_functions, random_seed)`
-
-    Le même que `ngrambf_v1`, mais stocke des jetons au lieu de ngrams. Les jetons sont des séquences séparées par des caractères non alphanumériques.
-
--   `bloom_filter([false_positive])` — Stores a [Filtre de Bloom](https://en.wikipedia.org/wiki/Bloom_filter) pour les colonnes spécifiées.
-
-    Facultatif `false_positive` le paramètre est la probabilité de recevoir une réponse faussement positive du filtre. Valeurs possibles: (0, 1). Valeur par défaut: 0.025.
-
-    Types de données pris en charge: `Int*`, `UInt*`, `Float*`, `Enum`, `Date`, `DateTime`, `String`, `FixedString`, `Array`, `LowCardinality`, `Nullable`.
-
-    Les fonctions suivantes peuvent l'utiliser: [égal](../../../sql-reference/functions/comparison-functions.md), [notEquals](../../../sql-reference/functions/comparison-functions.md), [dans](../../../sql-reference/functions/in-functions.md), [notIn](../../../sql-reference/functions/in-functions.md), [avoir](../../../sql-reference/functions/array-functions.md).
-
-<!-- -->
-
-``` sql
-INDEX sample_index (u64 * length(s)) TYPE minmax GRANULARITY 4
-INDEX sample_index2 (u64 * length(str), i32 + f64 * 100, date, str) TYPE set(100) GRANULARITY 4
-INDEX sample_index3 (lower(str), str) TYPE ngrambf_v1(3, 256, 2, 0) GRANULARITY 4
-```
-
-#### Les Fonctions De Soutien {#functions-support}
-
-Les Conditions dans le `WHERE` la clause contient des appels des fonctions qui fonctionnent avec des colonnes. Si la colonne fait partie d'un index, ClickHouse essaie d'utiliser cet index lors de l'exécution des fonctions. ClickHouse prend en charge différents sous-ensembles de fonctions pour l'utilisation d'index.
-
-Le `set` l'indice peut être utilisé avec toutes les fonctions. Les sous-ensembles de fonctions pour les autres index sont présentés dans le tableau ci-dessous.
-

-
-Les fonctions avec un argument constant inférieur à la taille ngram ne peuvent pas être utilisées par `ngrambf_v1` pour l'optimisation de la requête.
-
-Les filtres Bloom peuvent avoir des correspondances faussement positives, de sorte que le `ngrambf_v1`, `tokenbf_v1`, et `bloom_filter` les index ne peuvent pas être utilisés pour optimiser les requêtes où le résultat d'une fonction est censé être faux, par exemple:
-
--   Peut être optimisé:
-    -   `s LIKE '%test%'`
-    -   `NOT s NOT LIKE '%test%'`
-    -   `s = 1`
-    -   `NOT s != 1`
-    -   `startsWith(s, 'test')`
--   Ne peut pas être optimisé:
-    -   `NOT s LIKE '%test%'`
-    -   `s NOT LIKE '%test%'`
-    -   `NOT s = 1`
-    -   `s != 1`
-    -   `NOT startsWith(s, 'test')`
-
-## Accès Simultané Aux Données {#concurrent-data-access}
-
-Pour l'accès aux tables simultanées, nous utilisons le multi-versioning. En d'autres termes, lorsqu'une table est lue et mise à jour simultanément, les données sont lues à partir d'un ensemble de parties en cours au moment de la requête. Il n'y a pas de longues mèches. Les Inserts ne gênent pas les opérations de lecture.
-
-Lecture à partir d'un tableau est automatiquement parallélisée.
-
-## TTL pour les colonnes et les tableaux {#table_engine-mergetree-ttl}
-
-Détermine la durée de vie de des valeurs.
-
-Le `TTL` clause peut être définie pour la table entière et pour chaque colonne individuelle. Ttl de niveau Table peut également spécifier la logique de déplacement automatique des données entre les disques et les volumes.
-
-Les Expressions doivent évaluer pour [Date](../../../sql-reference/data-types/date.md) ou [DateTime](../../../sql-reference/data-types/datetime.md) type de données.
-
-Exemple:
-
-``` sql
-TTL time_column
-TTL time_column + interval
-```
-
-Définir `interval`, utiliser [intervalle](../../../sql-reference/operators/index.md#operators-datetime) opérateur.
-
-``` sql
-TTL date_time + INTERVAL 1 MONTH
-TTL date_time + INTERVAL 15 HOUR
-```
-
-### Colonne TTL {#mergetree-column-ttl}
-
-Lorsque les valeurs de la colonne expirent, ClickHouse les remplace par les valeurs par défaut du type de données de la colonne. Si toutes les valeurs de colonne de la partie données expirent, ClickHouse supprime cette colonne de la partie données d'un système de fichiers.
-
-Le `TTL` la clause ne peut pas être utilisée pour les colonnes clés.
-
-Exemple:
-
-Création d'une table avec TTL
-
-``` sql
-CREATE TABLE example_table
-(
-    d DateTime,
-    a Int TTL d + INTERVAL 1 MONTH,
-    b Int TTL d + INTERVAL 1 MONTH,
-    c String
-)
-ENGINE = MergeTree
-PARTITION BY toYYYYMM(d)
-ORDER BY d;
-```
-
-Ajout de TTL à une colonne d'une table existante
-
-``` sql
-ALTER TABLE example_table
-    MODIFY COLUMN
-    c String TTL d + INTERVAL 1 DAY;
-```
-
-Modification de TTL de la colonne
-
-``` sql
-ALTER TABLE example_table
-    MODIFY COLUMN
-    c String TTL d + INTERVAL 1 MONTH;
-```
-
-### Tableau TTL {#mergetree-table-ttl}
-
-Table peut avoir une expression pour la suppression de Lignes expirées, et plusieurs expressions pour le déplacement automatique de pièces entre [disques ou volumes](#table_engine-mergetree-multiple-volumes). Lorsque les lignes de la table expirent, ClickHouse supprime toutes les lignes correspondantes. Pour les pièces en mouvement, toutes les lignes d'une pièce doivent satisfaire aux critères d'expression de mouvement.
-
-``` sql
-TTL expr [DELETE|TO DISK 'aaa'|TO VOLUME 'bbb'], ...
-```
-
-Type de règle TTL peut suivre chaque expression TTL. Il affecte une action qui doit être faite une fois que l'expression est satisfaite (atteint l'heure actuelle):
-
--   `DELETE` - supprimer les Lignes expirées (action par défaut);
--   `TO DISK 'aaa'` - déplacer la partie sur le disque `aaa`;
--   `TO VOLUME 'bbb'` - déplacer la partie sur le disque `bbb`.
-
-Exemple:
-
-Création d'une table avec TTL
-
-``` sql
-CREATE TABLE example_table
-(
-    d DateTime,
-    a Int
-)
-ENGINE = MergeTree
-PARTITION BY toYYYYMM(d)
-ORDER BY d
-TTL d + INTERVAL 1 MONTH [DELETE],
-    d + INTERVAL 1 WEEK TO VOLUME 'aaa',
-    d + INTERVAL 2 WEEK TO DISK 'bbb';
-```
-
-Modification de TTL de la table
-
-``` sql
-ALTER TABLE example_table
-    MODIFY TTL d + INTERVAL 1 DAY;
-```
-
-**Suppression De Données**
-
-Les données avec un TTL expiré sont supprimées lorsque ClickHouse fusionne des parties de données.
-
-Lorsque ClickHouse voit que les données sont expirées, il effectue une fusion hors calendrier. Pour contrôler la fréquence de ces fusions, vous pouvez définir `merge_with_ttl_timeout`. Si la valeur est trop faible, il effectuera de nombreuses fusions hors calendrier qui peuvent consommer beaucoup de ressources.
-
-Si vous effectuez la `SELECT` requête entre les fusionne, vous pouvez obtenir des données expirées. Pour éviter cela, utilisez la [OPTIMIZE](../../../sql-reference/statements/misc.md#misc_operations-optimize) requête avant de l' `SELECT`.
-
-## Utilisation de plusieurs périphériques de bloc pour le stockage de données {#table_engine-mergetree-multiple-volumes}
-
-### Introduction {#introduction}
-
-`MergeTree` les moteurs de table de famille peuvent stocker des données sur plusieurs périphériques de bloc. Par exemple, il peut être utile lorsque les données d'un tableau sont implicitement divisé en “hot” et “cold”. Les données les plus récentes sont régulièrement demandées mais ne nécessitent qu'une petite quantité d'espace. Au contraire, les données historiques à queue grasse sont rarement demandées. Si plusieurs disques sont disponibles, la “hot” les données peuvent être situées sur des disques rapides (par exemple, SSD NVMe ou en mémoire), tandis que le “cold” des données relativement lente (par exemple, disque dur).
-
-La partie de données est l'unité mobile minimum pour `MergeTree`-tables de moteur. Les données appartenant à une partie sont stockées sur un disque. Les parties de données peuvent être déplacées entre les disques en arrière-plan (selon les paramètres de l'utilisateur) ainsi qu'au moyen du [ALTER](../../../sql-reference/statements/alter.md#alter_move-partition) requête.
-
-### Terme {#terms}
-
--   Disk — Block device mounted to the filesystem.
--   Default disk — Disk that stores the path specified in the [chemin](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-path) paramètre de serveur.
--   Volume — Ordered set of equal disks (similar to [JBOD](https://en.wikipedia.org/wiki/Non-RAID_drive_architectures)).
--   Storage policy — Set of volumes and the rules for moving data between them.
-
-Les noms donnés aux entités décrites peuvent être trouvés dans les tables système, [système.storage_policies](../../../operations/system-tables.md#system_tables-storage_policies) et [système.disque](../../../operations/system-tables.md#system_tables-disks). Pour appliquer l'une des stratégies de stockage configurées pour une table, utilisez `storage_policy` réglage de `MergeTree`-moteur de table de famille.
-
-### Configuration {#table_engine-mergetree-multiple-volumes_configure}
-
-Les disques, les volumes et les stratégies de stockage doivent être déclarés `<storage_configuration>` étiquette, soit dans le fichier principal `config.xml` ou dans un fichier distinct dans le `config.d` répertoire.
-
-Structure de Configuration:
-
-``` xml
-<storage_configuration>
-    <disks>
-        <disk_name_1> <!-- disk name -->
-            <path>/mnt/fast_ssd/clickhouse/</path>
-        </disk_name_1>
-        <disk_name_2>
-            <path>/mnt/hdd1/clickhouse/</path>
-            <keep_free_space_bytes>10485760</keep_free_space_bytes>
-        </disk_name_2>
-        <disk_name_3>
-            <path>/mnt/hdd2/clickhouse/</path>
-            <keep_free_space_bytes>10485760</keep_free_space_bytes>
-        </disk_name_3>
-
-        ...
-    </disks>
-
-    ...
-</storage_configuration>
-```
-
-Balise:
-
--   `<disk_name_N>` — Disk name. Names must be different for all disks.
--   `path` — path under which a server will store data (`data` et `shadow` des dossiers), doit être terminé par ‘/’.
--   `keep_free_space_bytes` — the amount of free disk space to be reserved.
-
-L'ordre du disque définition n'est pas important.
-
-Stratégies de stockage balisage de configuration:
-
-``` xml

-    ...
-    <policies>
-        <policy_name_1>
-            <volumes>
-                <volume_name_1>
-                    <disk>disk_name_from_disks_configuration</disk>
-                    <max_data_part_size_bytes>1073741824</max_data_part_size_bytes>
-                </volume_name_1>
-                <volume_name_2>
-                    <!-- configuration -->
-                </volume_name_2>
-                <!-- more volumes -->
-            </volumes>
-            <move_factor>0.2</move_factor>
-        </policy_name_1>
-        <policy_name_2>
-            <!-- configuration -->
-        </policy_name_2>
-
-        <!-- more policies -->
-    </policies>
-    ...
-</storage_configuration>
-```
-
-Balise:
-
--   `policy_name_N` — Policy name. Policy names must be unique.
--   `volume_name_N` — Volume name. Volume names must be unique.
--   `disk` — a disk within a volume.
--   `max_data_part_size_bytes` — the maximum size of a part that can be stored on any of the volume's disks.
--   `move_factor` — when the amount of available space gets lower than this factor, data automatically start to move on the next volume if any (by default, 0.1).
-
-Exemples de Cofiguration:
-
-``` xml
-<storage_configuration>
-    ...
-    <policies>
-        <hdd_in_order> <!-- policy name -->
-            <volumes>
-                <single> <!-- volume name -->
-                    <disk>disk1</disk>
-                    <disk>disk2</disk>
-                </single>
-            </volumes>
-        </hdd_in_order>
-
-        <moving_from_ssd_to_hdd>
-            <volumes>
-                <hot>
-                    <disk>fast_ssd</disk>
-                    <max_data_part_size_bytes>1073741824</max_data_part_size_bytes>
-                </hot>
-                <cold>
-                    <disk>disk1</disk>
-                </cold>
-            </volumes>
-            <move_factor>0.2</move_factor>
-        </moving_from_ssd_to_hdd>
-    </policies>
-    ...
-</storage_configuration>
-```
-
-Dans l'exemple donné, la `hdd_in_order` politique met en œuvre les [round-robin](https://en.wikipedia.org/wiki/Round-robin_scheduling) approche. Ainsi cette politique ne définit qu'un seul volume (`single`), les parties des données sont stockées sur tous ses disques dans l'ordre circulaire. Une telle politique peut être très utile s'il y a plusieurs disques similaires sont montés sur le système, mais RAID N'est pas configuré. Gardez à l'esprit que chaque lecteur de disque n'est pas fiable et vous pouvez compenser avec facteur de réplication de 3 ou plus.
-
-S'il existe différents types de disques disponibles dans le système, `moving_from_ssd_to_hdd` la stratégie peut être utilisée à la place. Volume `hot` se compose d'un disque SSD (`fast_ssd`), et la taille maximale d'une pièce qui peut être stocké sur ce volume est de 1 go. Toutes les pièces avec la taille plus grande que 1 GB sera stocké directement sur le `cold` le volume, qui contient un disque dur de disque `disk1`.
-Aussi, une fois le disque `fast_ssd` est complété par plus de 80%, les données seront transférées à la `disk1` par un processus d'arrière-plan.
-
-L'ordre d'énumération des volumes dans une stratégie de stockage est important. Une fois qu'un volume est surchargé, les données sont déplacées vers le suivant. L'ordre d'énumération des disques est important parce que les données sont stockées dans les virages.
-
-Lors de la création d'une table, on peut lui appliquer l'une des stratégies de stockage configurées:
-
-``` sql
-CREATE TABLE table_with_non_default_policy (
-    EventDate Date,
-    OrderID UInt64,
-    BannerID UInt64,
-    SearchPhrase String
-) ENGINE = MergeTree
-ORDER BY (OrderID, BannerID)
-PARTITION BY toYYYYMM(EventDate)
-SETTINGS storage_policy = 'moving_from_ssd_to_hdd'
-```
-
-Le `default` la Politique de stockage implique d'utiliser un seul volume, qui se compose d'un seul disque donné dans `<path>`. Une fois qu'une table est créée, sa stratégie de stockage ne peut pas être modifiée.
-
-### Détail {#details}
-
-Dans le cas de `MergeTree` les tableaux, les données sont sur le disque de différentes façons:
-
--   En tant que résultat d'un insert (`INSERT` requête).
--   En arrière-plan fusionne et [mutation](../../../sql-reference/statements/alter.md#alter-mutations).
--   Lors du téléchargement à partir d'une autre réplique.
--   À la suite du gel de la partition [ALTER TABLE … FREEZE PARTITION](../../../sql-reference/statements/alter.md#alter_freeze-partition).
-
-Dans tous ces cas, à l'exception des mutations et du gel de partition, une pièce est stockée sur un volume et un disque selon la Politique de stockage donnée:
-
-1.  Le premier volume (dans l'ordre de définition) qui a suffisamment d'espace disque pour stocker une pièce (`unreserved_space > current_part_size`) et permet de stocker des pièces d'une taille donnée (`max_data_part_size_bytes > current_part_size`) est choisi.
-2.  Dans ce volume, ce disque est choisi qui suit celui, qui a été utilisé pour stocker le bloc de données précédent, et qui a de l'espace libre plus que la taille de la pièce (`unreserved_space - keep_free_space_bytes > current_part_size`).
-
-Sous le capot, les mutations et la congélation des cloisons utilisent [des liens en dur](https://en.wikipedia.org/wiki/Hard_link). Les liens durs entre différents disques ne sont pas pris en charge, donc dans de tels cas, les pièces résultantes sont stockées sur les mêmes disques que les disques initiaux.
-
-En arrière - plan, les pièces sont déplacées entre les volumes en fonction de la quantité d'espace libre (`move_factor` paramètre) selon l'ordre les volumes sont déclarées dans le fichier de configuration.
-Les données ne sont jamais transférées du dernier et dans le premier. On peut utiliser des tables système [système.part_log](../../../operations/system-tables.md#system_tables-part-log) (champ `type = MOVE_PART`) et [système.partie](../../../operations/system-tables.md#system_tables-parts) (Fields `path` et `disk`) pour surveiller l'arrière-plan se déplace. Aussi, les informations détaillées peuvent être trouvées dans les journaux du serveur.
-
-L'utilisateur peut forcer le déplacement d'une partie ou d'une partition d'un volume à l'autre à l'aide de la requête [ALTER TABLE … MOVE PART\|PARTITION … TO VOLUME\|DISK …](../../../sql-reference/statements/alter.md#alter_move-partition), toutes les restrictions pour les opérations de fond sont prises en compte. La requête initie un mouvement seul et n'attend pas que les opérations d'arrière-plan soient terminées. L'utilisateur recevra un message d'erreur si pas assez d'espace libre est disponible ou si l'une des conditions requises ne sont pas remplies.
-
-Le déplacement des données n'interfère pas avec la réplication des données. Par conséquent, différentes stratégies de stockage peuvent être spécifiées pour la même table sur différents réplicas.
-
-Après l'achèvement des fusions d'arrière-plan et des mutations, les anciennes parties ne sont supprimées qu'après un certain temps (`old_parts_lifetime`).
-Pendant ce temps, ils ne sont pas déplacés vers d'autres volumes ou des disques. Par conséquent, jusqu'à ce que les pièces soient finalement supprimées, elles sont toujours prises en compte pour l'évaluation de l'espace disque occupé.

-# ReplacingMergeTree {#replacingmergetree}
-
-Le moteur diffère de [MergeTree](mergetree.md#table_engines-mergetree) en ce qu'il supprime les doublons avec la même valeur de clé primaire (ou, plus précisément, avec la même [clé de tri](mergetree.md) valeur).
-
-La déduplication des données se produit uniquement lors d'une fusion. La fusion se produit en arrière-plan à un moment inconnu, vous ne pouvez donc pas le planifier. Certaines des données peuvent rester non traitées. Bien que vous puissiez exécuter une fusion imprévue en utilisant le `OPTIMIZE` requête, ne comptez pas l'utiliser, parce que la `OPTIMIZE` requête va lire et écrire une grande quantité de données.
-
-Ainsi, `ReplacingMergeTree` convient pour effacer les données en double en arrière-plan afin d'économiser de l'espace, mais cela ne garantit pas l'absence de doublons.
-
-## Création d'une Table {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = ReplacingMergeTree([ver])
-[PARTITION BY expr]
-[ORDER BY expr]
-[PRIMARY KEY expr]
-[SAMPLE BY expr]
-[SETTINGS name=value, ...]
-```
-
-Pour une description des paramètres de requête, voir [demande de description](../../../sql-reference/statements/create.md).
-
-**ReplacingMergeTree Paramètres**
-
--   `ver` — column with version. Type `UInt*`, `Date` ou `DateTime`. Paramètre facultatif.
-
-    Lors de la fusion, `ReplacingMergeTree` de toutes les lignes avec la même clé primaire ne laisse qu'un:
-
-    -   Dernier dans la sélection, si `ver` pas ensemble.
-    -   Avec la version maximale, si `ver` défini.
-
-**Les clauses de requête**
-
-Lors de la création d'un `ReplacingMergeTree` la table de la même [clause](mergetree.md) sont nécessaires, comme lors de la création d'un `MergeTree` table.

-# Réplication Des Données {#table_engines-replication}
-
-La réplication n'est prise en charge que pour les tables de la famille MergeTree:
-
--   ReplicatedMergeTree
--   ReplicatedSummingMergeTree
--   ReplicatedReplacingMergeTree
--   ReplicatedAggregatingMergeTree
--   ReplicatedCollapsingMergeTree
--   ReplicatedVersionedCollapsingMergetree
--   ReplicatedGraphiteMergeTree
-
-La réplication fonctionne au niveau d'une table individuelle, Pas du serveur entier. Un serveur peut stocker des tables répliquées et non répliquées en même temps.
-
-La réplication ne dépend pas de la fragmentation. Chaque fragment a sa propre réplication indépendante.
-
-Données compressées pour `INSERT` et `ALTER` les requêtes sont répliquées (pour plus d'informations, consultez la documentation de [ALTER](../../../sql-reference/statements/alter.md#query_language_queries_alter)).
-
-`CREATE`, `DROP`, `ATTACH`, `DETACH` et `RENAME` les requêtes sont exécutées sur un seul serveur et ne sont pas répliquées:
-
--   Le `CREATE TABLE` query crée une nouvelle table réplicable sur le serveur où la requête est exécutée. Si cette table existe déjà sur d'autres serveurs, il ajoute une nouvelle réplique.
--   Le `DROP TABLE` requête supprime la réplique situé sur le serveur où l'exécution de la requête.
--   Le `RENAME` requête renomme la table sur l'une des répliques. En d'autres termes, les tables répliquées peuvent avoir des noms différents sur différentes répliques.
-
-Clickhouse utilise [Apache ZooKeeper](https://zookeeper.apache.org) pour stocker des informations méta répliques. Utilisez ZooKeeper version 3.4.5 ou plus récente.
-
-Pour utiliser la réplication, définissez les paramètres [zookeeper](../../../operations/server-configuration-parameters/settings.md#server-settings_zookeeper) section de configuration du serveur.
-
-!!! attention "Attention"
-    Ne négligez pas la sécurité. Clickhouse soutient le `digest` [Schéma ACL](https://zookeeper.apache.org/doc/current/zookeeperProgrammers.html#sc_ZooKeeperAccessControl) du sous-système de sécurité ZooKeeper.
-
-Exemple de définition des adresses du cluster ZooKeeper:
-
-``` xml
-<zookeeper>
-    <node index="1">
-        <host>example1</host>
-        <port>2181</port>
-    </node>
-    <node index="2">
-        <host>example2</host>
-        <port>2181</port>
-    </node>
-    <node index="3">
-        <host>example3</host>
-        <port>2181</port>
-    </node>
-</zookeeper>
-```
-
-Vous pouvez spécifier N'importe quel cluster Zookeeper existant et le système utilisera un répertoire pour ses propres données (le répertoire est spécifié lors de la création d'une table réplicable).
-
-Si ZooKeeper n'est pas défini dans le fichier de configuration, vous ne pouvez pas créer de tables répliquées et toutes les tables répliquées existantes seront en lecture seule.
-
-La gardienne n'est pas utilisé dans `SELECT` requêtes car la réplication n'affecte pas les performances de `SELECT` et les requêtes s'exécutent aussi vite que pour les tables non répliquées. Lors de l'interrogation de tables répliquées distribuées, le comportement de ClickHouse est contrôlé par les paramètres [max_replica_delay_for_distributed_queries](../../../operations/settings/settings.md#settings-max_replica_delay_for_distributed_queries) et [fallback_to_stale_replicas_for_distributed_queries](../../../operations/settings/settings.md#settings-fallback_to_stale_replicas_for_distributed_queries).
-
-Pour chaque `INSERT` requête, environ dix entrées sont ajoutées à ZooKeeper par le biais de plusieurs transactions. (Pour être plus précis, c'est pour chaque bloc de données inséré; une requête D'insertion contient un bloc ou un bloc par `max_insert_block_size = 1048576` rangée.) Cela conduit à des latences légèrement plus longues pour `INSERT` par rapport aux tables non répliquées. Mais si vous suivez les recommandations pour insérer des données dans des lots de pas plus d'un `INSERT` par seconde, cela ne crée aucun problème. L'ensemble du cluster clickhouse utilisé pour coordonner un cluster ZooKeeper a un total de plusieurs centaines `INSERTs` par seconde. Le débit sur les insertions de données (le nombre de lignes par seconde) est aussi élevé que pour les non-données répliquées.
-
-Pour les clusters très volumineux, vous pouvez utiliser différents clusters ZooKeeper pour différents fragments. Cependant, cela ne s'est pas avéré nécessaire sur le Yandex.Cluster Metrica (environ 300 serveurs).
-
-La réplication est asynchrone et multi-maître. `INSERT` les requêtes (ainsi que `ALTER`) peuvent être envoyés à n'importe quel serveur disponible. Les données sont insérées sur le serveur où la requête est exécutée, puis il est copié sur les autres serveurs. Comme il est asynchrone, les données récemment insérées apparaissent sur les autres répliques avec une certaine latence. Si une partie des répliques ne sont pas disponibles, les données sont écrites lorsqu'elles sont disponibles. Si une réplique est disponible, la latence correspond au temps nécessaire pour transférer le bloc de données compressées sur le réseau.
-
-Par défaut, une requête INSERT attend la confirmation de l'écriture des données à partir d'un seul réplica. Si les données ont été correctement écrit sur une seule réplique et le serveur avec cette réplique cesse d'exister, les données enregistrées seront perdues. Pour activer la confirmation des Écritures de données à partir de plusieurs réplicas, utilisez `insert_quorum` option.
-
-Chaque bloc de données est écrit de manière atomique. La requête D'insertion est divisée en blocs jusqu'à `max_insert_block_size = 1048576` rangée. En d'autres termes, si l' `INSERT` la requête a moins de 1048576 lignes, elle est faite de manière atomique.
-
-Les blocs de données sont dédupliquées. Pour plusieurs écritures du même bloc de données (blocs de données de même taille contenant les mêmes lignes dans le même ordre), le bloc n'est écrit qu'une seule fois. La raison en est en cas de défaillance du réseau lorsque l'application cliente ne sait pas si les données ont été écrites dans la base de données, de sorte que le `INSERT` requête peut simplement être répété. Peu importe à quelles insertions de réplica ont été envoyées avec des données identiques. `INSERTs` sont idempotents. Les paramètres de déduplication sont contrôlés par [merge_tree](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-merge_tree) les paramètres du serveur.
-
-Pendant la réplication, seules les données source à insérer sont transférées sur le réseau. D'autres transformations de données (fusion) sont coordonnées et effectuées sur toutes les répliques de la même manière. Cela minimise l'utilisation du réseau, ce qui signifie que la réplication fonctionne bien lorsque les répliques résident dans différents centres de données. (Notez que la duplication de données dans différents centres de données est l'objectif principal de la réplication.)
-
-Vous pouvez avoir n'importe quel nombre de répliques des mêmes données. Yandex.Metrica utilise la double réplication en production. Chaque serveur utilise RAID-5 ou RAID-6, et RAID-10 dans certains cas. C'est une solution relativement fiable et pratique.
-
-Le système surveille la synchronicité des données sur les répliques et est capable de récupérer après une défaillance. Le basculement est automatique (pour les petites différences de données) ou semi-automatique (lorsque les données diffèrent trop, ce qui peut indiquer une erreur de configuration).
-
-## Création De Tables Répliquées {#creating-replicated-tables}
-
-Le `Replicated` le préfixe est ajouté au nom du moteur de table. Exemple:`ReplicatedMergeTree`.
-
-**Répliqué \* MergeTree paramètres**
-
--   `zoo_path` — The path to the table in ZooKeeper.
--   `replica_name` — The replica name in ZooKeeper.
-
-Exemple:
-
-``` sql
-CREATE TABLE table_name
-(
-    EventDate DateTime,
-    CounterID UInt32,
-    UserID UInt32
-) ENGINE = ReplicatedMergeTree('/clickhouse/tables/{layer}-{shard}/table_name', '{replica}')
-PARTITION BY toYYYYMM(EventDate)
-ORDER BY (CounterID, EventDate, intHash32(UserID))
-SAMPLE BY intHash32(UserID)
-```
-
-<details markdown="1">
-
-<summary>Exemple de syntaxe obsolète</summary>
-
-``` sql
-CREATE TABLE table_name
-(
-    EventDate DateTime,
-    CounterID UInt32,
-    UserID UInt32
-) ENGINE = ReplicatedMergeTree('/clickhouse/tables/{layer}-{shard}/table_name', '{replica}', EventDate, intHash32(UserID), (CounterID, EventDate, intHash32(UserID), EventTime), 8192)
-```
-
-</details>
-
-Comme le montre l'exemple, ces paramètres peuvent contenir des substitutions entre crochets. Les valeurs substituées sont tirées de la ‘macros’ section du fichier de configuration. Exemple:
-
-``` xml
-<macros>
-    <layer>05</layer>
-    <shard>02</shard>
-    <replica>example05-02-1.yandex.ru</replica>
-</macros>
-```
-
-Le chemin d'accès à la table dans ZooKeeper doit être unique pour chaque table répliquée. Les Tables sur différents fragments doivent avoir des chemins différents.
-Dans ce cas, le chemin se compose des parties suivantes:
-
-`/clickhouse/tables/` est le préfixe commun. Nous vous recommandons d'utiliser exactement celui-ci.
-
-`{layer}-{shard}` est l'identificateur de fragment. Dans cet exemple, il se compose de deux parties, depuis l'Yandex.Le cluster Metrica utilise le sharding à deux niveaux. Pour la plupart des tâches, vous ne pouvez laisser que la substitution {shard}, qui sera étendue à l'Identificateur de partition.
-
-`table_name` est le nom du nœud de la table dans ZooKeeper. C'est une bonne idée de le rendre identique au nom de la table. Il est défini explicitement, car contrairement au nom de la table, il ne change pas après une requête de renommage.
-*HINT*: vous pouvez ajouter un nom de base de données devant `table_name` Aussi. E. g. `db_name.table_name`
-
-Le nom du réplica identifie différentes réplicas de la même table. Vous pouvez utiliser le nom de serveur pour cela, comme dans l'exemple. Le nom doit seulement être unique dans chaque fragment.
-
-Vous pouvez définir les paramètres explicitement au lieu d'utiliser des substitutions. Cela peut être pratique pour tester et configurer de petits clusters. Cependant, vous ne pouvez pas utiliser de requêtes DDL distribuées (`ON CLUSTER`) dans ce cas.
-
-Lorsque vous travaillez avec de grands clusters, nous vous recommandons d'utiliser des substitutions car elles réduisent la probabilité d'erreur.
-
-Exécutez l' `CREATE TABLE` requête sur chaque réplique. Cette requête crée une nouvelle table répliquée, ou ajoute une nouvelle réplique à un existant.
-
-Si vous ajoutez une nouvelle réplique après que la table contient déjà des données sur d'autres répliques, les données seront copiées des autres répliques vers la nouvelle après l'exécution de la requête. En d'autres termes, la nouvelle réplique synchronise avec les autres.
-
-Pour supprimer une réplique, exécutez `DROP TABLE`. However, only one replica is deleted – the one that resides on the server where you run the query.
-
-## Récupération Après Des Échecs {#recovery-after-failures}
-
-Si ZooKeeper n'est pas disponible au démarrage d'un serveur, les tables répliquées passent en mode Lecture seule. Le système tente périodiquement de se connecter à ZooKeeper.
-
-Si ZooKeeper est indisponible pendant un `INSERT`, ou une erreur se produit lors de l'interaction avec ZooKeeper, une exception est levée.
-
-Après la connexion à ZooKeeper, le système vérifie si l'ensemble de données du système de fichiers local correspond à l'ensemble de données attendu (ZooKeeper stocke ces informations). S'il y a des incohérences mineures, le système les résout en synchronisant les données avec les répliques.
-
-Si le système détecte des parties de données brisées (avec la mauvaise taille des fichiers) ou des parties non reconnues (parties écrites dans le système de fichiers mais non enregistrées dans ZooKeeper), il les déplace vers le `detached` sous-répertoire (ils ne sont pas supprimés). Toutes les pièces manquantes sont copiées à partir des répliques.
-
-Notez que ClickHouse n'effectue aucune action destructrice telle que la suppression automatique d'une grande quantité de données.
-
-Lorsque le serveur démarre (ou établit une nouvelle session avec ZooKeeper), il vérifie uniquement la quantité et la taille de tous les fichiers. Si les tailles de fichier correspondent mais que les octets ont été modifiés quelque part au milieu, cela n'est pas détecté immédiatement, mais uniquement lorsque vous tentez de lire les données `SELECT` requête. La requête lève une exception concernant une somme de contrôle ou une taille non correspondante d'un bloc compressé. Dans ce cas, des parties de données sont ajoutées à la file d'attente de vérification et copiées à partir des répliques si nécessaire.
-
-Si la série de données diffère trop de celle attendue, un mécanisme de sécurité est déclenché. Le serveur entre cela dans le journal et refuse de lancer. La raison en est que ce cas peut indiquer une erreur de configuration, par exemple si une réplique sur un fragment a été accidentellement configurée comme une réplique sur un fragment différent. Cependant, les seuils pour ce mécanisme sont fixés assez bas, et cette situation peut se produire pendant la récupération normale de la défaillance. Dans ce cas, les données sont restaurées semi-automatiquement - par “pushing a button”.
-
-Pour démarrer la récupération, créez le nœud `/path_to_table/replica_name/flags/force_restore_data` dans ZooKeeper avec n'importe quel contenu, ou exécutez la commande pour restaurer toutes les tables répliquées:
-
-``` bash
-sudo -u clickhouse touch /var/lib/clickhouse/flags/force_restore_data
-```
-
-Puis redémarrez le serveur. Au démarrage, le serveur supprime ces indicateurs et démarre la récupération.
-
-## Récupération Après La Perte De Données Complète {#recovery-after-complete-data-loss}
-
-Si toutes les données et métadonnées ont disparu de l'un des serveurs, procédez comme suit pour la récupération:
-
-1.  Installez ClickHouse sur le serveur. Définissez correctement les substitutions dans le fichier de configuration qui contient l'Identificateur de fragment et les répliques, si vous les utilisez.
-2.  Si vous avez des tables non compliquées qui doivent être dupliquées manuellement sur les serveurs, copiez leurs données à partir d'un réplica (dans le répertoire `/var/lib/clickhouse/data/db_name/table_name/`).
-3.  Copier les définitions de table situées dans `/var/lib/clickhouse/metadata/` à partir d'une réplique. Si un identificateur de fragment ou de réplica est défini explicitement dans les définitions de table, corrigez-le de manière à ce qu'il corresponde à ce réplica. (Alternativement, démarrez le serveur et faites tous les `ATTACH TABLE` les requêtes qui auraient dû être dans les .les fichiers sql dans `/var/lib/clickhouse/metadata/`.)
-4.  Pour démarrer la récupération, créez le nœud ZooKeeper `/path_to_table/replica_name/flags/force_restore_data` tout contenu, ou d'exécuter la commande pour restaurer toutes les tables répliquées: `sudo -u clickhouse touch /var/lib/clickhouse/flags/force_restore_data`
-
-Ensuite, démarrez le serveur (redémarrez, s'il est déjà en cours d'exécution). Les données seront téléchargées à partir de répliques.
-
-Une autre option de récupération consiste à supprimer des informations sur la réplique perdue de ZooKeeper (`/path_to_table/replica_name`), puis créez à nouveau la réplique comme décrit dans “[Création de tables répliquées](#creating-replicated-tables)”.
-
-Il n'y a aucune restriction sur la bande passante réseau pendant la récupération. Gardez cela à l'esprit si vous restaurez de nombreuses répliques à la fois.
-
-## Conversion de MergeTree en ReplicatedMergeTree {#converting-from-mergetree-to-replicatedmergetree}
-
-Nous utilisons le terme `MergeTree` pour consulter tous les moteurs de la `MergeTree family` le même que pour `ReplicatedMergeTree`.
-
-Si vous avez eu une `MergeTree` table qui a été répliquée manuellement, vous pouvez le convertir en une table répliquée. Vous devrez peut-être le faire si vous avez déjà recueilli une grande quantité de données dans un `MergeTree` table et maintenant vous voulez activer la réplication.
-
-Si les données diffèrent sur différentes répliques, synchronisez-les d'abord ou supprimez-les sur toutes les répliques sauf une.
-
-Renommez la table mergetree existante, puis créez un `ReplicatedMergeTree` table avec l'ancien nom.
-Déplacez les données de l'ancienne table vers `detached` sous-répertoire à l'intérieur du répertoire avec les nouvelles données de la table (`/var/lib/clickhouse/data/db_name/table_name/`).
-Ensuite, exécutez `ALTER TABLE ATTACH PARTITION` sur l'une des répliques d'ajouter ces données à des parties de l'ensemble de travail.
-
-## Conversion de ReplicatedMergeTree en MergeTree {#converting-from-replicatedmergetree-to-mergetree}
-
-Créez une table MergeTree avec un nom différent. Déplacez toutes les données du répertoire avec le `ReplicatedMergeTree` données de la table dans le répertoire de données de la nouvelle table. Ensuite, supprimer le `ReplicatedMergeTree` table et redémarrez le serveur.
-
-Si vous voulez vous débarrasser d'un `ReplicatedMergeTree` table sans lancer le serveur:
-
--   Supprimer la `.sql` fichier dans le répertoire de métadonnées (`/var/lib/clickhouse/metadata/`).
--   Supprimer le chemin correspondant dans ZooKeeper (`/path_to_table/replica_name`).
-
-Après cela, vous pouvez lancer le serveur, créer un `MergeTree` tableau, déplacer les données de son répertoire, puis redémarrez le serveur.
-
-## Récupération lorsque les métadonnées du Cluster Zookeeper sont perdues ou endommagées {#recovery-when-metadata-in-the-zookeeper-cluster-is-lost-or-damaged}
-
-Si les données de ZooKeeper ont été perdues ou endommagées, vous pouvez les enregistrer en les déplaçant dans une table non compliquée comme décrit ci-dessus.

-# SummingMergeTree {#summingmergetree}
-
-Le moteur hérite de [MergeTree](mergetree.md#table_engines-mergetree). La différence est que lors de la fusion de parties de données pour `SummingMergeTree` tables ClickHouse remplace toutes les lignes avec la même clé primaire (ou, plus précisément, avec la même [clé de tri](mergetree.md)) avec une ligne qui contient des valeurs résumées pour les colonnes avec le type de données numériques. Si la clé de tri est composée de telle sorte qu'une seule valeur de clé correspond à un grand nombre de lignes, cela réduit considérablement le volume de stockage et accélère la sélection des données.
-
-Nous vous recommandons d'utiliser le moteur avec `MergeTree`. Stocker des données complètes dans `MergeTree` table, et l'utilisation `SummingMergeTree` pour le stockage de données agrégées, par exemple, lors de la préparation de rapports. Une telle approche vous empêchera de perdre des données précieuses en raison d'une clé primaire mal composée.
-
-## Création d'une Table {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE = SummingMergeTree([columns])
-[PARTITION BY expr]
-[ORDER BY expr]
-[SAMPLE BY expr]
-[SETTINGS name=value, ...]
-```
-
-Pour une description des paramètres de requête, voir [demande de description](../../../sql-reference/statements/create.md).
-
-**Paramètres de SummingMergeTree**
-
--   `columns` - un n-uplet avec les noms de colonnes où les valeurs seront résumées. Paramètre facultatif.
-    Les colonnes doivent être d'un type numérique et ne doit pas être dans la clé primaire.
-
-    Si `columns` non spécifié, ClickHouse résume les valeurs dans toutes les colonnes avec un type de données numérique qui ne sont pas dans la clé primaire.
-
-**Les clauses de requête**
-
-Lors de la création d'un `SummingMergeTree` la table de la même [clause](mergetree.md) sont nécessaires, comme lors de la création d'un `MergeTree` table.

-<summary>Méthode obsolète pour créer une Table</summary>
-
-!!! attention "Attention"
-    N'utilisez pas cette méthode dans les nouveaux projets et, si possible, remplacez les anciens projets par la méthode décrite ci-dessus.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-) ENGINE [=] SummingMergeTree(date-column [, sampling_expression], (primary, key), index_granularity, [columns])
-```
-
-Tous les paramètres excepté `columns` ont la même signification que dans `MergeTree`.
-
--   `columns` — tuple with names of columns values of which will be summarized. Optional parameter. For a description, see the text above.
-
-</details>
-
-## Exemple D'Utilisation {#usage-example}
-
-Considérons le tableau suivant:
-
-``` sql
-CREATE TABLE summtt
-(
-    key UInt32,
-    value UInt32
-)
-ENGINE = SummingMergeTree()
-ORDER BY key
-```
-
-Insérer des données:
-
-``` sql
-INSERT INTO summtt Values(1,1),(1,2),(2,1)
-```
-
-ClickHouse peut résumer toutes les lignes pas complètement ([voir ci-dessous](#data-processing)), nous utilisons donc une fonction d'agrégation `sum` et `GROUP BY` la clause dans la requête.
-
-``` sql
-SELECT key, sum(value) FROM summtt GROUP BY key
-```
-
-``` text
-┌─key─┬─sum(value)─┐
-│   2 │          1 │
-│   1 │          3 │
-└─────┴────────────┘
-```
-
-## Le Traitement Des Données {#data-processing}
-
-Lorsque les données sont insérées dans une table, elles sont enregistrées telles quelles. Clickhouse fusionne périodiquement les parties de données insérées et c'est à ce moment que les lignes avec la même clé primaire sont additionnées et remplacées par une pour chaque partie de données résultante.
-
-ClickHouse can merge the data parts so that different resulting parts of data cat consist rows with the same primary key, i.e. the summation will be incomplete. Therefore (`SELECT`) une fonction d'agrégation [somme()](../../../sql-reference/aggregate-functions/reference.md#agg_function-sum) et `GROUP BY` la clause doit être utilisé dans une requête comme décrit dans l'exemple ci-dessus.
-
-### Règles communes pour la sommation {#common-rules-for-summation}
-
-Les valeurs dans les colonnes avec le type de données numériques sont résumées. L'ensemble des colonnes est défini par le paramètre `columns`.
-
-Si les valeurs étaient 0 dans toutes les colonnes pour la sommation, la ligne est supprimée.
-
-Si la colonne n'est pas dans la clé primaire et n'est pas résumée, une valeur arbitraire est sélectionnée parmi celles existantes.
-
-Les valeurs ne sont pas résumés des colonnes de la clé primaire.
-
-### La somme dans les colonnes Aggregatefunction {#the-summation-in-the-aggregatefunction-columns}
-
-Pour les colonnes de [Type AggregateFunction](../../../sql-reference/data-types/aggregatefunction.md) ClickHouse se comporte comme [AggregatingMergeTree](aggregatingmergetree.md) moteur d'agrégation selon la fonction.
-
-### Structures Imbriquées {#nested-structures}
-
-Table peut avoir des structures de données imbriquées qui sont traitées d'une manière spéciale.
-
-Si le nom d'une table imbriquée se termine avec `Map` et il contient au moins deux colonnes qui répondent aux critères suivants:
-
--   la première colonne est numérique `(*Int*, Date, DateTime)` ou une chaîne de caractères `(String, FixedString)`, nous allons l'appeler `key`,
--   les autres colonnes sont arithmétique `(*Int*, Float32/64)`, nous allons l'appeler `(values...)`,
-
-ensuite, cette table imbriquée est interprétée comme un mappage de `key => (values...)` et lors de la fusion de ses lignes, les éléments de deux ensembles de données sont regroupées par `key` avec une sommation du correspondant `(values...)`.
-
-Exemple:
-
-``` text
-[(1, 100)] + [(2, 150)] -> [(1, 100), (2, 150)]
-[(1, 100)] + [(1, 150)] -> [(1, 250)]
-[(1, 100)] + [(1, 150), (2, 150)] -> [(1, 250), (2, 150)]
-[(1, 100), (2, 150)] + [(1, -100)] -> [(2, 150)]
-```
-
-Lorsque vous demandez des données, utilisez [sumMap (clé, valeur)](../../../sql-reference/aggregate-functions/reference.md) fonction pour l'agrégation de `Map`.
-
-Pour la structure de données imbriquée, vous n'avez pas besoin de spécifier ses colonnes dans le tuple de colonnes pour la sommation.

-
-Le moteur hérite de [MergeTree](mergetree.md#table_engines-mergetree) et ajoute la logique de réduction des lignes à l'algorithme de fusion des parties de données. `VersionedCollapsingMergeTree` sert le même but que [CollapsingMergeTree](collapsingmergetree.md) mais utilise un autre effondrement algorithme qui permet d'insérer les données dans n'importe quel ordre avec plusieurs threads. En particulier, l' `Version` la colonne aide à réduire correctement les lignes même si elles sont insérées dans le mauvais ordre. Contrairement, `CollapsingMergeTree` permet uniquement une insertion strictement consécutive.

-
-## Effondrer {#table_engines_versionedcollapsingmergetree}
-
-### Données {#data}
-
-Considérez une situation où vous devez enregistrer des données en constante évolution pour un objet. Il est raisonnable d'avoir une ligne pour un objet et de mettre à jour la ligne chaque fois qu'il y a des modifications. Cependant, l'opération de mise à jour est coûteuse et lente pour un SGBD car elle nécessite la réécriture des données dans le stockage. La mise à jour n'est pas acceptable si vous devez écrire des données rapidement, mais vous pouvez écrire les modifications sur un objet de manière séquentielle comme suit.
-
-L'utilisation de la `Sign` colonne lors de l'écriture de la ligne. Si `Sign = 1` cela signifie que la ligne est un état d'un objet (appelons-la “state” rangée). Si `Sign = -1` il indique l'annulation de l'état d'un objet avec les mêmes attributs (appelons-la “cancel” rangée). Également utiliser l' `Version` colonne, qui doit identifier chaque état d'un objet avec un numéro distinct.
-
-Par exemple, nous voulons calculer le nombre de pages visitées sur le site et combien de temps ils étaient là. À un moment donné nous écrivons la ligne suivante avec l'état de l'activité de l'utilisateur:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐
-│ 4324182021466249494 │         5 │      146 │    1 │       1 |
-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-À un moment donné, nous enregistrons le changement d'activité de l'utilisateur et l'écrivons avec les deux lignes suivantes.
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │       1 |
-│ 4324182021466249494 │         6 │      185 │    1 │       2 |
-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-La première ligne annule le précédent état de l'objet (utilisateur). Il doit copier tous les champs de l'état annulé sauf `Sign`.
-
-La deuxième ligne contient l'état actuel.
-
-Parce que nous avons besoin seulement le dernier état de l'activité de l'utilisateur, les lignes
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┬─Version─┐
-│ 4324182021466249494 │         5 │      146 │    1 │       1 |
-│ 4324182021466249494 │         5 │      146 │   -1 │       1 |
-└─────────────────────┴───────────┴──────────┴──────┴─────────┘
-```
-
-peut être supprimé, réduisant l'état invalide (ancien) de l'objet. `VersionedCollapsingMergeTree` fait cela lors de la fusion des parties de données.
-
-Pour savoir pourquoi nous avons besoin de deux lignes pour chaque changement, voir [Algorithme](#table_engines-versionedcollapsingmergetree-algorithm).
-
-**Notes sur l'Utilisation de la**
-
-1.  Le programme qui écrit les données devraient se souvenir de l'état d'un objet afin de l'annuler. Le “cancel” chaîne doit être une copie de la “state” chaîne avec le contraire `Sign`. Cela augmente la taille initiale de stockage, mais permet d'écrire les données rapidement.
-2.  Les tableaux de plus en plus longs dans les colonnes réduisent l'efficacité du moteur en raison de la charge d'écriture. Plus les données sont simples, meilleure est l'efficacité.
-3.  `SELECT` les résultats dépendent fortement de la cohérence de l'histoire de l'objet change. Être précis lors de la préparation des données pour l'insertion. Vous pouvez obtenir des résultats imprévisibles avec des données incohérentes, telles que des valeurs négatives pour des métriques non négatives telles que la profondeur de session.
-
-### Algorithme {#table_engines-versionedcollapsingmergetree-algorithm}
-
-Lorsque ClickHouse fusionne des parties de données, il supprime chaque paire de lignes ayant la même clé primaire et la même version et différentes `Sign`. L'ordre des lignes n'a pas d'importance.
-
-Lorsque ClickHouse insère des données, il ordonne les lignes par la clé primaire. Si l' `Version` la colonne n'est pas dans la clé primaire, ClickHouse ajoute à la clé primaire implicitement que le dernier champ et l'utilise pour la commande.
-
-## La Sélection De Données {#selecting-data}
-
-ClickHouse ne garantit pas que toutes les lignes avec la même clé primaire sera dans la même partie des données ou même sur le même serveur physique. Cela est vrai à la fois pour l'écriture des données et pour la fusion ultérieure des parties de données. En outre, les processus ClickHouse `SELECT` requêtes avec plusieurs threads, et il ne peut pas prédire l'ordre des lignes dans le résultat. Cela signifie que le regroupement est nécessaire s'il est nécessaire pour obtenir complètement “collapsed” données à partir d'un `VersionedCollapsingMergeTree` table.
-
-Pour finaliser la réduction, écrivez une requête avec un `GROUP BY` fonctions de clause et d'agrégation qui tiennent compte du signe. Par exemple, pour calculer la quantité, l'utilisation `sum(Sign)` plutôt `count()`. Pour calculer la somme de quelque chose, utilisez `sum(Sign * x)` plutôt `sum(x)` et d'ajouter `HAVING sum(Sign) > 0`.
-
-Aggregate `count`, `sum` et `avg` peut être calculée de cette manière. Aggregate `uniq` peut être calculé si un objet a au moins un non-état effondré. Aggregate `min` et `max` ne peut pas être calculé, car `VersionedCollapsingMergeTree` ne sauvegarde pas l'historique des valeurs des États réduits.
-
-Si vous avez besoin d'extraire les données avec “collapsing” mais sans agrégation (par exemple, pour vérifier si des lignes sont présentes dont les valeurs les plus récentes correspondent à certaines conditions), vous pouvez utiliser `FINAL` le modificateur du `FROM` clause. Cette approche est inefficace et ne devrait pas être utilisée avec de grandes tables.

-Création de la table:
-
-``` sql
-CREATE TABLE UAct
-(
-    UserID UInt64,
-    PageViews UInt8,
-    Duration UInt8,
-    Sign Int8,
-    Version UInt8
-)
-ENGINE = VersionedCollapsingMergeTree(Sign, Version)
-ORDER BY UserID
-```
-
-Insérer les données:
-
-``` sql
-INSERT INTO UAct VALUES (4324182021466249494, 5, 146, 1, 1)

-
-Nous utilisons deux `INSERT` requêtes pour créer deux parties de données différentes. Si nous insérons les données avec une seule requête, ClickHouse crée une partie de données et n'effectuera jamais de fusion.

-Que voyons-nous ici et où sont les parties effondrées?
-Nous avons créé deux parties de données en utilisant deux `INSERT` requête. Le `SELECT` la requête a été effectuée dans deux threads, et le résultat est un ordre aléatoire de lignes.
-L'effondrement n'a pas eu lieu car les parties de données n'ont pas encore été fusionnées. ClickHouse fusionne des parties de données à un moment inconnu que nous ne pouvons pas prédire.
-
-C'est pourquoi nous avons besoin de l'agrégation:
-
-``` sql
-SELECT
-    UserID,
-    sum(PageViews * Sign) AS PageViews,
-    sum(Duration * Sign) AS Duration,
-    Version
-FROM UAct
-GROUP BY UserID, Version
-HAVING sum(Sign) > 0
-```

-└─────────────────────┴───────────┴──────────┴─────────┘
-```
-
-Si nous n'avons pas besoin d'agrégation et que nous voulons forcer l'effondrement, nous pouvons utiliser le `FINAL` le modificateur du `FROM` clause.
-
-``` sql
-SELECT * FROM UAct FINAL
-```
-

-
-C'est un moyen très inefficace de sélectionner des données. Ne l'utilisez pas pour les grandes tables.

-# Tampon {#buffer}
-
-Met en mémoire tampon les données à écrire dans la RAM, les vidant périodiquement dans une autre table. Pendant l'opération de lecture, les données sont lues à partir de la mémoire tampon, et l'autre simultanément.
-
-``` sql
-Buffer(database, table, num_layers, min_time, max_time, min_rows, max_rows, min_bytes, max_bytes)
-```
-
-Les paramètres du moteur:
-
--   `database` – Database name. Instead of the database name, you can use a constant expression that returns a string.
--   `table` – Table to flush data to.
--   `num_layers` – Parallelism layer. Physically, the table will be represented as `num_layers` indépendant de tampons. Valeur recommandée: 16.
--   `min_time`, `max_time`, `min_rows`, `max_rows`, `min_bytes`, et `max_bytes` – Conditions for flushing data from the buffer.
-
-Les données sont vidées du tampon et écrites dans la table de destination si toutes les `min*` conditions ou au moins un `max*` conditions sont remplies.
-
--   `min_time`, `max_time` – Condition for the time in seconds from the moment of the first write to the buffer.
--   `min_rows`, `max_rows` – Condition for the number of rows in the buffer.
--   `min_bytes`, `max_bytes` – Condition for the number of bytes in the buffer.
-
-Pendant l'opération d'écriture, les données sont insérées dans un `num_layers` nombre aléatoire de tampons. Ou, si la partie de données à insérer est suffisamment grande (supérieure à `max_rows` ou `max_bytes`), il est écrit directement dans la table de destination, en omettant le tampon.
-
-Les conditions de purger les données sont calculées séparément pour chacun des `num_layers` tampon. Par exemple, si `num_layers = 16` et `max_bytes = 100000000`, la consommation maximale de RAM est de 1,6 Go.
-
-Exemple:
-
-``` sql
-CREATE TABLE merge.hits_buffer AS merge.hits ENGINE = Buffer(merge, hits, 16, 10, 100, 10000, 1000000, 10000000, 100000000)
-```
-
-La création d'un ‘merge.hits_buffer’ table avec la même structure que ‘merge.hits’ et en utilisant le moteur tampon. Lors de l'écriture dans cette table, les données sont mises en mémoire tampon dans la RAM ‘merge.hits’ table. 16 tampons sont créés. Les données dans chacun d'entre eux est rincé si 100 secondes sont écoulées, ou un million de lignes ont été écrites, ou 100 MO de données ont été écrits; ou si, simultanément, 10 secondes et 10 000 lignes et 10 MO de données ont été écrites. Par exemple, si une ligne a été écrite, après 100 secondes, il sera vidé, n'importe quoi. Mais si plusieurs lignes ont été écrites, les données seront vidées plus tôt.
-
-Lorsque le serveur est arrêté, avec DROP TABLE ou DETACH TABLE, les données du tampon sont également vidées vers la table de destination.
-
-Vous pouvez définir des chaînes vides entre guillemets simples pour le nom de la base de données et de la table. Cela indique l'absence d'une table de destination. Dans ce cas, lorsque les conditions de vidage des données sont atteintes, le tampon est simplement effacé. Cela peut être utile pour garder une fenêtre de données dans la mémoire.
-
-Lors de la lecture à partir d'une table tampon, les données sont traitées à la fois à partir du tampon et de la table de destination (s'il y en a une).
-Notez que les tables de tampon ne prennent pas en charge un index. En d'autres termes, les données dans le tampon sont entièrement analysées, ce qui peut être lent pour les grands tampons. (Pour les données dans une table subordonnée, l'index qu'il prend en charge sera utilisé.)
-
-Si l'ensemble de colonnes de la table tampon ne correspond pas à l'ensemble de colonnes d'une table subordonnée, un sous-ensemble de colonnes existant dans les deux tables est inséré.
-
-Si les types ne correspondent pas à l'une des colonnes de la table tampon et à une table subordonnée, un message d'erreur est entré dans le journal du serveur et le tampon est effacé.
-La même chose se produit si la table subordonnée n'existe pas lorsque le tampon est vidé.
-
-Si vous devez exécuter ALTER pour une table subordonnée et la table tampon, nous vous recommandons de supprimer d'abord la table tampon, d'exécuter ALTER pour la table subordonnée, puis de créer à nouveau la table tampon.
-
-Si le serveur est redémarré anormalement, les données dans le tampon sont perdues.
-
-FINAL et SAMPLE ne fonctionnent pas correctement pour les tables tampon. Ces conditions sont transmises à la table de destination, mais ne sont pas utilisées pour traiter les données dans le tampon. Si ces fonctionnalités sont nécessaires, nous vous recommandons d'utiliser uniquement la table tampon pour l'écriture, lors de la lecture à partir de la table de destination.
-
-Lors de l'ajout de données à un Tampon, un des tampons est verrouillé. Cela entraîne des retards si une opération de lecture est effectuée simultanément à partir de la table.
-
-Les données insérées dans une table tampon peuvent se retrouver dans la table subordonnée dans un ordre différent et dans des blocs différents. Pour cette raison, une table tampon est difficile à utiliser pour écrire correctement dans un CollapsingMergeTree. Pour éviter les problèmes, vous pouvez définir ‘num_layers’ 1.
-
-Si la table de destination est répliquée, certaines caractéristiques attendues des tables répliquées sont perdues lors de l'écriture dans une table tampon. Les modifications aléatoires apportées à l'ordre des lignes et des tailles des parties de données provoquent l'arrêt de la déduplication des données, ce qui signifie qu'il n'est pas possible d'avoir un ‘exactly once’ Ecrire dans des tables répliquées.
-
-En raison de ces inconvénients, nous ne pouvons recommander l'utilisation d'une table tampon que dans de rares cas.
-
-Une table tampon est utilisée lorsque trop D'insertions sont reçues d'un grand nombre de serveurs sur une unité de temps et que les données ne peuvent pas être mises en mémoire tampon avant l'insertion, ce qui signifie que les insertions ne peuvent pas s'exécuter assez rapidement.
-
-Notez qu'il n'est pas judicieux d'insérer des données d'une ligne de temps, même pour Tampon tables. Cela ne produira qu'une vitesse de quelques milliers de lignes par seconde, tandis que l'insertion de blocs de données plus grands peut produire plus d'un million de lignes par seconde (voir la section “Performance”).

-# Distribué {#distributed}
-
-**Les Tables avec moteur distribué ne stockent aucune donnée par elles mêmes**, mais autoriser le traitement des requêtes distribuées sur plusieurs serveurs.
-La lecture est automatiquement parallélisée. Lors d'une lecture, les index de table sur les serveurs distants sont utilisés, s'il y en a.
-
-Le moteur distribué accepte les paramètres:
-
--   le nom du cluster dans le fichier de configuration du serveur
-
--   le nom d'une base de données distante
-
--   le nom d'une table distante
-
--   (en option) sharding clé
-
--   (éventuellement) nom de la stratégie, il sera utilisé pour stocker des fichiers temporaires pour l'envoi asynchrone
-
-    Voir aussi:
-
-    -   `insert_distributed_sync` paramètre
-    -   [MergeTree](../mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes) pour les exemples
-
-Exemple:
-
-``` sql
-Distributed(logs, default, hits[, sharding_key[, policy_name]])
-```
-
-Les données seront lues à partir de tous les serveurs ‘logs’ cluster, à partir de la valeur par défaut.hits table située sur chaque serveur du cluster.
-Les données ne sont pas seulement lues mais sont partiellement traitées sur les serveurs distants (dans la mesure du possible).
-Par exemple, pour une requête avec GROUP BY, les données seront agrégées sur des serveurs distants et les états intermédiaires des fonctions d'agrégation seront envoyés au serveur demandeur. Ensuite, les données seront plus agrégées.
-
-Au lieu du nom de la base de données, vous pouvez utiliser une expression constante qui renvoie une chaîne. Par exemple: currentDatabase().
-
-logs – The cluster name in the server's config file.
-
-Les Clusters sont définis comme ceci:
-
-``` xml
-<remote_servers>
-    <logs>
-        <shard>
-            <!-- Optional. Shard weight when writing data. Default: 1. -->
-            <weight>1</weight>
-            <!-- Optional. Whether to write data to just one of the replicas. Default: false (write data to all replicas). -->
-            <internal_replication>false</internal_replication>
-            <replica>
-                <host>example01-01-1</host>
-                <port>9000</port>
-            </replica>
-            <replica>
-                <host>example01-01-2</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-        <shard>
-            <weight>2</weight>
-            <internal_replication>false</internal_replication>
-            <replica>
-                <host>example01-02-1</host>
-                <port>9000</port>
-            </replica>
-            <replica>

-                <port>9440</port>
-            </replica>
-        </shard>
-    </logs>
-</remote_servers>
-```
-
-Ici un cluster est défini avec le nom ‘logs’ qui se compose de deux fragments, dont chacune contient deux répliques.
-Les partitions se réfèrent aux serveurs qui contiennent différentes parties des données (pour lire toutes les données, vous devez accéder à tous les partitions).
-Les répliques sont des serveurs de duplication (afin de lire toutes les données, vous pouvez accéder aux données sur l'une des répliques).
-
-Les noms de Cluster ne doivent pas contenir de points.
-
-Paramètre `host`, `port` et , éventuellement, `user`, `password`, `secure`, `compression` sont spécifiés pour chaque serveur:
-- `host` – The address of the remote server. You can use either the domain or the IPv4 or IPv6 address. If you specify the domain, the server makes a DNS request when it starts, and the result is stored as long as the server is running. If the DNS request fails, the server doesn't start. If you change the DNS record, restart the server.
-- `port` – The TCP port for messenger activity (‘tcp_port’ dans la configuration, généralement définie sur 9000). Ne le confondez pas avec http_port.
-- `user` – Name of the user for connecting to a remote server. Default value: default. This user must have access to connect to the specified server. Access is configured in the users.xml file. For more information, see the section [Les droits d'accès](../../../operations/access-rights.md).
-- `password` – The password for connecting to a remote server (not masked). Default value: empty string.
-- `secure` - Utilisez ssl pour la connexion, généralement vous devez également définir `port` = 9440. Le serveur doit écouter `<tcp_port_secure>9440</tcp_port_secure>` et avoir des certificats corrects.
-- `compression` - Utiliser la compression de données. Valeur par défaut: true.
-
-When specifying replicas, one of the available replicas will be selected for each of the shards when reading. You can configure the algorithm for load balancing (the preference for which replica to access) – see the [équilibrage](../../../operations/settings/settings.md#settings-load_balancing) paramètre.
-Si la connexion avec le serveur n'est pas établie, il y aura une tentative de connexion avec un court délai. Si la connexion échoue, la réplique suivante sera sélectionnée, et ainsi de suite pour toutes les répliques. Si la tentative de connexion a échoué pour toutes les répliques, la tentative sera répété de la même façon, plusieurs fois.
-Cela fonctionne en faveur de la résilience, mais ne fournit pas de tolérance aux pannes complète: un serveur distant peut accepter la connexion, mais peut ne pas fonctionner ou fonctionner mal.
-
-Vous pouvez spécifier un seul des fragments (dans ce cas, le traitement de la requête doit être appelé distant, plutôt que distribué) ou jusqu'à un nombre quelconque de fragments. Dans chaque fragment, vous pouvez spécifier un nombre de répliques. Vous pouvez spécifier un nombre différent de répliques pour chaque fragment.
-
-Vous pouvez spécifier autant de clusters que vous souhaitez dans la configuration.
-
-Pour afficher vos clusters, utilisez ‘system.clusters’ table.
-
-Le moteur distribué permet de travailler avec un cluster comme un serveur local. Cependant, le cluster est inextensible: vous devez écrire sa configuration dans le fichier de configuration du serveur (encore mieux, pour tous les serveurs du cluster).
-
-The Distributed engine requires writing clusters to the config file. Clusters from the config file are updated on the fly, without restarting the server. If you need to send a query to an unknown set of shards and replicas each time, you don't need to create a Distributed table – use the ‘remote’ fonction de table à la place. Voir la section [Les fonctions de Table](../../../sql-reference/table-functions/index.md).
-
-Il existe deux méthodes pour écrire des données dans un cluster:
-
-Tout d'abord, vous pouvez définir les serveurs d'écrire les données à et effectuer l'écriture directement sur chaque fragment. En d'autres termes, effectuez INSERT dans les tables que la table distribuée “looks at”. C'est la solution la plus flexible car vous pouvez utiliser n'importe quel schéma de sharding, qui pourrait être non trivial en raison des exigences du sujet. C'est également la solution la plus optimale puisque les données peuvent être écrites sur différents fragments de manière complètement indépendante.
-
-Deuxièmement, vous pouvez effectuer INSERT dans une table distribuée. Dans ce cas, la table distribuera les données insérées sur les serveurs eux-mêmes. Pour écrire dans une table distribuée, elle doit avoir un jeu de clés de sharding (le dernier paramètre). De plus, s'il n'y a qu'un seul fragment, l'opération d'écriture fonctionne sans spécifier la clé de sharding, car cela ne signifie rien dans ce cas.
-
-Chaque fragment peut avoir un poids défini dans le fichier de configuration. Par défaut, le poids est égal à un. Les données sont réparties entre les fragments dans la quantité proportionnelle au poids des fragments. Par exemple, si il y a deux tessons et le premier a un poids de 9 tandis que la seconde a un poids de 10, le premier sera envoyé 9 / 19 parties de lignes, et le second sera envoyé 10 / 19.
-
-Chaque fragment peut avoir le ‘internal_replication’ paramètre défini dans le fichier de configuration.
-
-Si ce paramètre est défini à ‘true’, l'opération d'écriture sélectionne le premier saine réplique et écrit les données. Utilisez cette option si le tableau Distribué “looks at” tables répliquées. En d'autres termes, si la table où les données seront écrites va répliquer elle-même.
-
-Si elle est définie sur ‘false’ (par défaut), les données sont écrites dans toutes les répliques. En substance, cela signifie que la table distribuée réplique les données elle-même. C'est pire que d'utiliser des tables répliquées, car la cohérence des répliques n'est pas vérifiée et, au fil du temps, elles contiendront des données légèrement différentes.
-
-Pour sélectionner le fragment auquel une ligne de données est envoyée, l'expression de sharding est analysée et son reste est extrait de la diviser par le poids total des fragments. La ligne est envoyée au fragment qui correspond au demi-intervalle des restes de ‘prev_weight’ de ‘prev_weights + weight’, où ‘prev_weights’ c'est le poids total des tessons avec le plus petit nombre, et ‘weight’ est le poids de cet éclat. Par exemple, s'il y a deux fragments, et que le premier a un poids de 9 tandis que le second a un poids de 10, la ligne sera envoyée au premier fragment pour les restes de la plage \[0, 9), et au second pour les restes de la plage \[9, 19).
-
-L'expression de sharding peut être n'importe quelle expression de constantes et de colonnes de table qui renvoie un entier. Par exemple, vous pouvez utiliser l'expression ‘rand()’ pour la distribution aléatoire des données, ou ‘UserID’ pour la distribution par le reste de la division de L'ID de l'utilisateur (alors les données d'un seul utilisateur résideront sur un seul fragment, ce qui simplifie l'exécution et la jointure par les utilisateurs). Si l'une des colonnes n'est pas assez répartie uniformément, vous pouvez l'envelopper dans une fonction de hachage: intHash64 (UserID).
-
-Un simple rappel de la division est une solution limitée pour le sharding et n'est pas toujours approprié. Cela fonctionne pour des volumes de données moyens et importants (des dizaines de serveurs), mais pas pour des volumes de données très importants (des centaines de serveurs ou plus). Dans ce dernier cas, utilisez le schéma de répartition requis par le domaine, plutôt que d'utiliser des entrées dans des tableaux distribués.
-
-SELECT queries are sent to all the shards and work regardless of how data is distributed across the shards (they can be distributed completely randomly). When you add a new shard, you don't have to transfer the old data to it. You can write new data with a heavier weight – the data will be distributed slightly unevenly, but queries will work correctly and efficiently.
-
-Vous devriez être préoccupé par le système de sharding dans les cas suivants:
-
--   Les requêtes sont utilisées qui nécessitent des données de jointure (IN ou JOIN) par une clé spécifique. Si les données sont partagées par cette clé, vous pouvez utiliser local in ou JOIN au lieu de GLOBAL IN ou global JOIN, ce qui est beaucoup plus efficace.
--   Un grand nombre de serveurs est utilisé (des centaines ou plus) avec un grand nombre de petites requêtes (requêtes de clients individuels - sites Web, annonceurs ou partenaires). Pour que les petites requêtes n'affectent pas l'ensemble du cluster, il est logique de localiser les données d'un seul client sur un seul fragment. Alternativement, comme nous l'avons fait dans Yandex.Metrica, vous pouvez configurer le sharding à deux niveaux: divisez le cluster entier en “layers”, où une couche peut être constituée de plusieurs éclats. Les données d'un seul client sont situées sur une seule couche, mais des fragments peuvent être ajoutés à une couche si nécessaire, et les données sont distribuées aléatoirement à l'intérieur de celles-ci. Des tables distribuées sont créées pour chaque couche et une seule table distribuée partagée est créée pour les requêtes globales.
-
-Les données sont écrites de manière asynchrone. Lorsqu'il est inséré dans la table, le bloc de données est simplement écrit dans le système de fichiers local. Les données sont envoyées aux serveurs distants en arrière-plan dès que possible. La période d'envoi des données est gérée par [distributed_directory_monitor_sleep_time_ms](../../../operations/settings/settings.md#distributed_directory_monitor_sleep_time_ms) et [distributed_directory_monitor_max_sleep_time_ms](../../../operations/settings/settings.md#distributed_directory_monitor_max_sleep_time_ms) paramètre. Le `Distributed` moteur envoie chaque fichier de données insérées séparément, mais vous pouvez activer le lot envoi de fichiers avec l' [distributed_directory_monitor_batch_inserts](../../../operations/settings/settings.md#distributed_directory_monitor_batch_inserts) paramètre. Ce paramètre améliore les performances du cluster en utilisant mieux les ressources réseau et serveur local. Vous devriez vérifier si les données sont envoyées avec succès en vérifiant la liste des fichiers (données en attente d'envoi) dans le répertoire de la table: `/var/lib/clickhouse/data/database/table/`.
-
-Si le serveur a cessé d'exister ou a subi un redémarrage Brutal (par exemple, après une panne de périphérique) après une insertion dans une table distribuée, les données insérées peuvent être perdues. Si une partie de données endommagée est détectée dans le répertoire de la table, elle est transférée ‘broken’ sous-répertoire et n'est plus utilisé.
-

-# Données externes pour le traitement des requêtes {#external-data-for-query-processing}
-
-ClickHouse permet d'Envoyer à un serveur les données nécessaires au traitement d'une requête, ainsi qu'une requête SELECT. Ces données sont placées dans une table temporaire (voir la section “Temporary tables”) et peut être utilisé dans la requête (par exemple, dans les DANS les opérateurs).
-
-Par exemple, si vous disposez d'un fichier texte avec important des identifiants d'utilisateur, vous pouvez le télécharger sur le serveur avec une requête qui utilise la filtration par cette liste.
-
-Si vous devez exécuter plusieurs requêtes avec un volume important de données externes, n'utilisez pas cette fonctionnalité. Il est préférable de télécharger les données sur la base de données à l'avance.
-
-Les données externes peuvent être téléchargées à l'aide du client de ligne de commande (en mode non interactif) ou à l'aide de L'interface HTTP.
-
-Dans le client de ligne de commande, vous pouvez spécifier une section paramètres du format
-
-``` bash
---external --file=... [--name=...] [--format=...] [--types=...|--structure=...]
-```
-
-Vous pouvez avoir plusieurs sections comme ça, pour le nombre de tables étant transmis.
-
-**–external** – Marks the beginning of a clause.
-**–file** – Path to the file with the table dump, or -, which refers to stdin.
-Une seule table peut être récupérée à partir de stdin.
-
-Les paramètres suivants sont facultatifs: **–name**– Name of the table. If omitted, _data is used.
-**–format** – Data format in the file. If omitted, TabSeparated is used.
-
-L'un des paramètres suivants est requis:**–types** – A list of comma-separated column types. For example: `UInt64,String`. The columns will be named _1, _2, …
-**–structure**– The table structure in the format`UserID UInt64`, `URL String`. Définit les noms et les types de colonnes.
-
-Les fichiers spécifiés dans ‘file’ sera analysé par le format spécifié dans ‘format’, en utilisant les types de données spécifié dans ‘types’ ou ‘structure’. La table sera téléchargée sur le serveur et accessible en tant que table temporaire avec le nom dans ‘name’.
-
-Exemple:
-
-``` bash
-$ echo -ne "1\n2\n3\n" | clickhouse-client --query="SELECT count() FROM test.visits WHERE TraficSourceID IN _data" --external --file=- --types=Int8
-849897
-$ cat /etc/passwd | sed 's/:/\t/g' | clickhouse-client --query="SELECT shell, count() AS c FROM passwd GROUP BY shell ORDER BY c DESC" --external --file=- --name=passwd --structure='login String, unused String, uid UInt16, gid UInt16, comment String, home String, shell String'
-/bin/sh 20
-/bin/false      5
-/bin/bash       4
-/usr/sbin/nologin       1
-/bin/sync       1
-```
-
-Lors de l'utilisation de L'interface HTTP, les données externes sont transmises au format multipart/form-data. Chaque tableau est transmis en tant que fichier séparé. Le nom de la table est tiré du nom du fichier. Le ‘query_string’ est passé les paramètres ‘name_format’, ‘name_types’, et ‘name_structure’, où ‘name’ est le nom de la table que ces paramètres correspondent. La signification des paramètres est la même que lors de l'utilisation du client de ligne de commande.
-
-Exemple:
-
-``` bash
-$ cat /etc/passwd | sed 's/:/\t/g' > passwd.tsv
-
-$ curl -F 'passwd=@passwd.tsv;' 'http://localhost:8123/?query=SELECT+shell,+count()+AS+c+FROM+passwd+GROUP+BY+shell+ORDER+BY+c+DESC&passwd_structure=login+String,+unused+String,+uid+UInt16,+gid+UInt16,+comment+String,+home+String,+shell+String'

-/bin/false      5
-/bin/bash       4
-/usr/sbin/nologin       1
-/bin/sync       1
-```
-
-Pour le traitement des requêtes distribuées, les tables temporaires sont envoyées à tous les serveurs distants.

----
-
-# Fichier {#table_engines-file}
-
-Le moteur de table de fichiers conserve les données dans un fichier dans l'un des [fichier
-format](../../../interfaces/formats.md#formats) (TabSeparated, Native, etc.).
-
-Exemples d'utilisation:
-
--   Exportation de données de ClickHouse vers un fichier.
--   Convertir des données d'un format à un autre.
--   Mise à jour des données dans ClickHouse via l'édition d'un fichier sur un disque.
-
-## Utilisation dans le serveur ClickHouse {#usage-in-clickhouse-server}
-
-``` sql
-File(Format)
-```
-
-Le `Format` paramètre spécifie l'un des formats de fichier disponibles. Effectuer
-`SELECT` requêtes, le format doit être pris en charge pour l'entrée, et à effectuer
-`INSERT` queries – for output. The available formats are listed in the
-[Format](../../../interfaces/formats.md#formats) section.
-
-ClickHouse ne permet pas de spécifier le chemin du système de fichiers pour`File`. Il utilisera le dossier défini par [chemin](../../../operations/server-configuration-parameters/settings.md) réglage dans la configuration du serveur.
-
-Lors de la création de la table en utilisant `File(Format)` il crée sous-répertoire vide dans ce dossier. Lorsque les données sont écrites dans cette table, elles sont mises dans `data.Format` fichier dans ce répertoire.
-
-Vous pouvez créer manuellement ce sous dossier et ce fichier dans le système de fichiers [ATTACH](../../../sql-reference/statements/misc.md) il à la table des informations avec le nom correspondant, de sorte que vous pouvez interroger les données de ce fichier.
-
-!!! warning "Avertissement"
-    Soyez prudent avec cette fonctionnalité, car ClickHouse ne garde pas trace des modifications externes apportées à ces fichiers. Le résultat des Écritures simultanées via ClickHouse et en dehors de ClickHouse n'est pas défini.
-
-**Exemple:**
-
-**1.** Configurer le `file_engine_table` table:
-
-``` sql
-CREATE TABLE file_engine_table (name String, value UInt32) ENGINE=File(TabSeparated)
-```
-
-Par défaut ClickHouse va créer un dossier `/var/lib/clickhouse/data/default/file_engine_table`.
-
-**2.** Créer manuellement `/var/lib/clickhouse/data/default/file_engine_table/data.TabSeparated` contenant:
-
-``` bash
-$ cat data.TabSeparated
-one 1
-two 2
-```
-
-**3.** Interroger les données:
-
-``` sql
-SELECT * FROM file_engine_table
-```
-
-``` text
-┌─name─┬─value─┐
-│ one  │     1 │
-│ two  │     2 │
-└──────┴───────┘
-```
-
-## Utilisation dans ClickHouse-local {#usage-in-clickhouse-local}
-
-Dans [clickhouse-local](../../../operations/utilities/clickhouse-local.md) Fichier moteur accepte chemin d'accès au fichier en plus `Format`. Les flux d'entrée / sortie par défaut peuvent être spécifiés en utilisant des noms numériques ou lisibles par l'homme comme `0` ou `stdin`, `1` ou `stdout`.
-**Exemple:**
-
-``` bash
-$ echo -e "1,2\n3,4" | clickhouse-local -q "CREATE TABLE table (a Int64, b Int64) ENGINE = File(CSV, stdin); SELECT a, b FROM table; DROP TABLE table"
-```
-
-## Les détails de mise en Œuvre {#details-of-implementation}
-
--   Plusieurs `SELECT` les requêtes peuvent être effectuées simultanément, mais `INSERT` requêtes s'attendre les uns les autres.
--   Prise en charge de la création d'un nouveau fichier par `INSERT` requête.
--   Si le fichier existe, `INSERT` ajouterait de nouvelles valeurs dedans.
--   Pas pris en charge:

-# Rejoindre {#join}
-
-Structure de données préparée pour l'utilisation dans [JOIN](../../../sql-reference/statements/select/join.md#select-join) opérations.
-
-## Création d'une Table {#creating-a-table}
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
-) ENGINE = Join(join_strictness, join_type, k1[, k2, ...])
-```
-
-Voir la description détaillée de la [CREATE TABLE](../../../sql-reference/statements/create.md#create-table-query) requête.
-
-**Les Paramètres Du Moteur**
-
--   `join_strictness` – [ADHÉRER à la rigueur](../../../sql-reference/statements/select/join.md#select-join-types).
--   `join_type` – [Type de jointure](../../../sql-reference/statements/select/join.md#select-join-types).
--   `k1[, k2, ...]` – Key columns from the `USING` la clause que l' `JOIN` l'opération est faite avec de la.
-
-Entrer `join_strictness` et `join_type` paramètres sans guillemets, par exemple, `Join(ANY, LEFT, col1)`. Ils doivent correspondre à la `JOIN` fonctionnement que le tableau sera utilisé pour. Si les paramètres ne correspondent pas, ClickHouse ne lance pas d'exception et peut renvoyer des données incorrectes.
-
-## Utilisation Du Tableau {#table-usage}
-
-### Exemple {#example}
-
-Création de la table de gauche:
-
-``` sql
-CREATE TABLE id_val(`id` UInt32, `val` UInt32) ENGINE = TinyLog
-```
-
-``` sql
-INSERT INTO id_val VALUES (1,11)(2,12)(3,13)
-```
-
-Création du côté droit `Join` table:
-
-``` sql
-CREATE TABLE id_val_join(`id` UInt32, `val` UInt8) ENGINE = Join(ANY, LEFT, id)
-```
-
-``` sql
-INSERT INTO id_val_join VALUES (1,21)(1,22)(3,23)
-```
-
-Rejoindre les tables:
-
-``` sql
-SELECT * FROM id_val ANY LEFT JOIN id_val_join USING (id) SETTINGS join_use_nulls = 1
-```
-
-``` text
-┌─id─┬─val─┬─id_val_join.val─┐
-│  1 │  11 │              21 │
-│  2 │  12 │            ᴺᵁᴸᴸ │
-│  3 │  13 │              23 │
-└────┴─────┴─────────────────┘
-```
-
-Comme alternative, vous pouvez récupérer des données de la `Join` table, spécifiant la valeur de la clé de jointure:
-
-``` sql
-SELECT joinGet('id_val_join', 'val', toUInt32(1))
-```
-
-``` text
-┌─joinGet('id_val_join', 'val', toUInt32(1))─┐
-│                                         21 │
-└────────────────────────────────────────────┘
-```
-
-### Sélection et insertion de données {#selecting-and-inserting-data}
-
-Vous pouvez utiliser `INSERT` requêtes pour ajouter des données au `Join`-tables de moteur. Si la table a été créée avec `ANY` rigueur, les données pour les clés en double sont ignorées. Avec l' `ALL` rigueur, toutes les lignes sont ajoutées.
-
-Vous ne pouvez pas effectuer un `SELECT` requête directement à partir de la table. Au lieu de cela, utilisez l'une des méthodes suivantes:
-
--   Placez la table sur le côté droit dans un `JOIN` clause.
--   Appelez le [joinGet](../../../sql-reference/functions/other-functions.md#joinget) fonction, qui vous permet d'extraire des données de la table de la même manière que d'un dictionnaire.
-
-### Limitations et paramètres {#join-limitations-and-settings}
-
-Lors de la création d'un tableau, les paramètres suivants sont appliqués:
-
--   [join_use_nulls](../../../operations/settings/settings.md#join_use_nulls)
--   [max_rows_in_join](../../../operations/settings/query-complexity.md#settings-max_rows_in_join)
--   [max_bytes_in_join](../../../operations/settings/query-complexity.md#settings-max_bytes_in_join)
--   [join_overflow_mode](../../../operations/settings/query-complexity.md#settings-join_overflow_mode)
--   [join_any_take_last_row](../../../operations/settings/settings.md#settings-join_any_take_last_row)
-
-Le `Join`- les tables de moteur ne peuvent pas être utilisées dans `GLOBAL JOIN` opérations.
-
-Le `Join`-moteur permet d'utiliser [join_use_nulls](../../../operations/settings/settings.md#join_use_nulls) réglage de la `CREATE TABLE` déclaration. Et [SELECT](../../../sql-reference/statements/select/index.md) requête permet d'utiliser `join_use_nulls` trop. Si vous avez différents `join_use_nulls` paramètres, vous pouvez obtenir une table de jointure d'erreur. Il dépend de type de JOINTURE. Lorsque vous utilisez [joinGet](../../../sql-reference/functions/other-functions.md#joinget) fonction, vous devez utiliser le même `join_use_nulls` réglage en `CRATE TABLE` et `SELECT` déclaration.
-
-## Le Stockage De Données {#data-storage}
-
-`Join` les données de la table sont toujours situées dans la RAM. Lors de l'insertion de lignes dans une table, ClickHouse écrit des blocs de données dans le répertoire du disque afin qu'ils puissent être restaurés lorsque le serveur redémarre.
-
-Si le serveur redémarre incorrectement, le bloc de données sur le disque peut être perdu ou endommagé. Dans ce cas, vous devrez peut-être supprimer manuellement le fichier contenant des données endommagées.

-# Mémoire {#memory}
-
-Le moteur de mémoire stocke les données en RAM, sous forme non compressée. Les données sont stockées exactement sous la même forme qu'elles sont reçues lors de la lecture. En d'autres termes, la lecture de ce tableau est entièrement gratuit.
-L'accès aux données simultanées est synchronisé. Les verrous sont courts: les opérations de lecture et d'écriture ne se bloquent pas.
-Les index ne sont pas pris en charge. La lecture est parallélisée.
-La productivité maximale (plus de 10 Go / s) est atteinte sur les requêtes simples, car il n'y a pas de lecture à partir du disque, de décompression ou de désérialisation des données. (Il convient de noter que dans de nombreux cas, la productivité du moteur MergeTree est presque aussi élevée.)
-Lors du redémarrage d'un serveur, les données disparaissent de la table et la table devient vide.
-Normalement, l'utilisation de ce moteur de table n'est pas justifiée. Cependant, il peut être utilisé pour des tests, et pour des tâches où la vitesse maximale est requise sur un nombre relativement faible de lignes (jusqu'à environ 100 000 000).
-
-Le moteur de mémoire est utilisé par le système pour les tables temporaires avec des données de requête externes (voir la section “External data for processing a query”), et pour la mise en œuvre globale dans (voir la section “IN operators”).

-# Fusionner {#merge}
-
-Le `Merge` moteur (à ne pas confondre avec `MergeTree`) ne stocke pas les données elles-mêmes, mais permet la lecture de n'importe quel nombre d'autres tables simultanément.
-La lecture est automatiquement parallélisée. L'écriture dans une table n'est pas prise en charge. Lors de la lecture, les index des tables en cours de lecture sont utilisés, s'ils existent.
-Le `Merge` engine accepte les paramètres: le nom de la base de données et une expression régulière pour les tables.
-
-Exemple:
-
-``` sql
-Merge(hits, '^WatchLog')
-```
-
-Les données seront lues à partir des tableaux du `hits` base de données dont les noms correspondent à l'expression régulière ‘`^WatchLog`’.
-
-Au lieu du nom de la base de données, vous pouvez utiliser une expression constante qui renvoie une chaîne. Exemple, `currentDatabase()`.
-
-Regular expressions — [re2](https://github.com/google/re2) (prend en charge un sous-ensemble de PCRE), sensible à la casse.
-Voir les notes sur les symboles d'échappement dans les expressions régulières “match” section.
-
-Lors de la sélection des tables à lire, le `Merge` le tableau lui-même ne sera pas choisie, même si elle correspond à l'expression rationnelle. C'est pour éviter les boucles.
-Il est possible de créer deux `Merge` des tables qui essaieront sans cesse de lire les données des autres, mais ce n'est pas une bonne idée.
-
-L'utilisation traditionnelle de la `Merge` moteur pour travailler avec un grand nombre de `TinyLog` les tables comme si avec une seule table.
-
-Exemple 2:
-
-Disons que vous avez une ancienne table (WatchLog_old) et que vous avez décidé de changer de partitionnement sans déplacer les données vers une nouvelle table (WatchLog_new) et que vous devez voir les données des deux tables.
-
-``` sql
-CREATE TABLE WatchLog_old(date Date, UserId Int64, EventType String, Cnt UInt64)
-ENGINE=MergeTree(date, (UserId, EventType), 8192);
-INSERT INTO WatchLog_old VALUES ('2018-01-01', 1, 'hit', 3);
-
-CREATE TABLE WatchLog_new(date Date, UserId Int64, EventType String, Cnt UInt64)
-ENGINE=MergeTree PARTITION BY date ORDER BY (UserId, EventType) SETTINGS index_granularity=8192;
-INSERT INTO WatchLog_new VALUES ('2018-01-02', 2, 'hit', 3);
-
-CREATE TABLE WatchLog as WatchLog_old ENGINE=Merge(currentDatabase(), '^WatchLog');
-
-SELECT *
-FROM WatchLog
-```

-# Définir {#set}
-
-Un ensemble de données qui est toujours en RAM. Il est conçu pour être utilisé sur le côté droit de l'opérateur (voir la section “IN operators”).
-
-Vous pouvez utiliser INSERT pour insérer des données dans la table. De nouveaux éléments seront ajoutés à l'ensemble de données, tandis que les doublons seront ignorés.
-Mais vous ne pouvez pas effectuer SELECT à partir de la table. La seule façon de récupérer des données est en l'utilisant dans la moitié droite de l'opérateur.
-
-Les données sont toujours situées dans la RAM. Pour INSERT, les blocs de données insérées sont également écrits dans le répertoire des tables sur le disque. Lors du démarrage du serveur, ces données sont chargées dans la RAM. En d'autres termes, après le redémarrage, les données restent en place.
-
-Pour un redémarrage brutal du serveur, le bloc de données sur le disque peut être perdu ou endommagé. Dans ce dernier cas, vous devrez peut-être supprimer manuellement le fichier contenant des données endommagées.

-# URL (URL, Format) {#table_engines-url}
-
-Gère les données sur un serveur HTTP / HTTPS distant. Ce moteur est similaire
-à l' [Fichier](file.md) moteur.
-
-## Utilisation du moteur dans le serveur ClickHouse {#using-the-engine-in-the-clickhouse-server}
-
-Le `format` doit être celui que ClickHouse peut utiliser dans
-`SELECT` les requêtes et, si nécessaire, en `INSERTs`. Pour la liste complète des formats pris en charge, voir
-[Format](../../../interfaces/formats.md#formats).
-
-Le `URL` doit être conforme à la structure D'un Localisateur de ressources uniforme. L'URL spécifiée doit pointer vers un serveur
-qui utilise le protocole HTTP ou HTTPS. Cela ne nécessite pas de
-en-têtes supplémentaires pour obtenir une réponse du serveur.
-
-`INSERT` et `SELECT` les requêtes sont transformées en `POST` et `GET` demande,
-respectivement. Pour le traitement `POST` demandes, le serveur distant doit prendre en charge
-[Encodage de transfert en morceaux](https://en.wikipedia.org/wiki/Chunked_transfer_encoding).
-
-Vous pouvez limiter le nombre maximal de sauts de redirection HTTP GET en utilisant [max_http_get_redirects](../../../operations/settings/settings.md#setting-max_http_get_redirects) paramètre.
-
-**Exemple:**
-
-**1.** Créer un `url_engine_table` table sur le serveur :
-
-``` sql
-CREATE TABLE url_engine_table (word String, value UInt64)
-ENGINE=URL('http://127.0.0.1:12345/', CSV)
-```
-
-**2.** Créez un serveur HTTP de base à l'aide des outils Python 3 standard et
-démarrer:
-
-``` python3
-from http.server import BaseHTTPRequestHandler, HTTPServer
-
-class CSVHTTPServer(BaseHTTPRequestHandler):
-    def do_GET(self):
-        self.send_response(200)
-        self.send_header('Content-type', 'text/csv')
-        self.end_headers()
-
-        self.wfile.write(bytes('Hello,1\nWorld,2\n', "utf-8"))
-
-if __name__ == "__main__":
-    server_address = ('127.0.0.1', 12345)
-    HTTPServer(server_address, CSVHTTPServer).serve_forever()
-```
-
-``` bash
-$ python3 server.py
-```
-
-**3.** Les données de la demande:
-
-``` sql
-SELECT * FROM url_engine_table
-```
-
-``` text
-┌─word──┬─value─┐
-│ Hello │     1 │
-│ World │     2 │
-└───────┴───────┘
-```

----
-
-# Questions Générales {#general-questions}
-
-## Pourquoi Ne Pas Utiliser Quelque Chose Comme MapReduce? {#why-not-use-something-like-mapreduce}
-
-Nous pouvons nous référer à des systèmes comme MapReduce en tant que systèmes informatiques distribués dans lesquels l'opération de réduction est basée sur le tri distribué. La solution open-source la plus courante dans cette classe est [Apache Hadoop](http://hadoop.apache.org). Yandex utilise sa solution interne, YT.
-
-Ces systèmes ne sont pas appropriés pour les requêtes en ligne en raison de leur latence élevée. En d'autres termes, ils ne peuvent pas être utilisés comme back-end pour une interface web. Ces types de systèmes ne sont pas utiles pour les mises à jour de données en temps réel. Le tri distribué n'est pas la meilleure façon d'effectuer des opérations de réduction si le résultat de l'opération et tous les résultats intermédiaires (s'il y en a) sont situés dans la RAM d'un seul serveur, ce qui est généralement le cas pour les requêtes en ligne. Dans un tel cas, une table de hachage est un moyen optimal d'effectuer des opérations de réduction. Une approche courante pour optimiser les tâches map-reduce est la pré-agrégation (réduction partielle) à l'aide d'une table de hachage en RAM. L'utilisateur effectue cette optimisation manuellement. Le tri distribué est l'une des principales causes de réduction des performances lors de l'exécution de tâches simples de réduction de la carte.
-
-La plupart des implémentations MapReduce vous permettent d'exécuter du code arbitraire sur un cluster. Mais un langage de requête déclaratif est mieux adapté à OLAP pour exécuter des expériences rapidement. Par exemple, Hadoop a ruche et Cochon. Considérez également Cloudera Impala ou Shark (obsolète) pour Spark, ainsi que Spark SQL, Presto et Apache Drill. Les performances lors de l'exécution de telles tâches sont très sous-optimales par rapport aux systèmes spécialisés, mais une latence relativement élevée rend irréaliste l'utilisation de ces systèmes comme backend pour une interface web.
-
-## Que Faire si j'ai un problème avec les encodages lors de l'utilisation D'Oracle via ODBC? {#oracle-odbc-encodings}
-
-Si vous utilisez Oracle via le pilote ODBC comme source de dictionnaires externes, vous devez définir la valeur correcte pour `NLS_LANG` variable d'environnement dans `/etc/default/clickhouse`. Pour plus d'informations, voir le [FAQ Oracle NLS_LANG](https://www.oracle.com/technetwork/products/globalization/nls-lang-099431.html).
-
-**Exemple**
-
-``` sql
-NLS_LANG=RUSSIAN_RUSSIA.UTF8
-```
-
-## Comment exporter des données de ClickHouse vers un fichier? {#how-to-export-to-file}
-
-### Utilisation de la Clause INTO OUTFILE {#using-into-outfile-clause}
-
-Ajouter un [INTO OUTFILE](../sql-reference/statements/select/into-outfile.md#into-outfile-clause) clause à votre requête.
-
-Exemple:
-
-``` sql
-SELECT * FROM table INTO OUTFILE 'file'
-```
-
-Par défaut, ClickHouse utilise [TabSeparated](../interfaces/formats.md#tabseparated) format pour les données de sortie. Pour sélectionner le [format de données](../interfaces/formats.md), utiliser le [FORMAT de la clause](../sql-reference/statements/select/format.md#format-clause).
-
-Exemple:
-
-``` sql
-SELECT * FROM table INTO OUTFILE 'file' FORMAT CSV
-```
-
-### Utilisation d'une Table de moteur de fichiers {#using-a-file-engine-table}
-
-Voir [Fichier](../engines/table-engines/special/file.md).
-
-### Utilisation De La Redirection En Ligne De Commande {#using-command-line-redirection}
-
-``` sql
-$ clickhouse-client --query "SELECT * from table" --format FormatName > result.txt
-```
-
-Voir [clickhouse-client](../interfaces/cli.md).

-## Exemple De Requêtes {#example-queries}
-
-[Tutoriel ClickHouse](../../getting-started/tutorial.md) est basé sur Yandex.Metrica dataset et la façon recommandée pour commencer avec cet ensemble de données est de simplement passer par tutoriel.
-
-D'autres exemples de requêtes pour ces tables peuvent être trouvés parmi [tests avec État](https://github.com/ClickHouse/ClickHouse/tree/master/tests/queries/1_stateful) de ClickHouse (ils sont nommés `test.hists` et `test.visits` y).

-# New York Taxi Données {#new-york-taxi-data}
-
-Ce jeu de données peut être obtenu de deux façons:
-
--   importation à partir de données brutes
--   téléchargement de partitions
-
-## Comment importer les données brutes {#how-to-import-the-raw-data}
-
-Tu vois https://github.com/toddwschneider/nyc-taxi-data et http://tech.marksblogg.com/billion-nyc-taxi-rides-redshift.html pour la description d'un ensemble de données et les instructions de téléchargement.
-
-Le téléchargement entraînera environ 227 Go de données non compressées dans des fichiers CSV. Le téléchargement prend environ une heure sur une connexion 1 Gbit (téléchargement parallèle depuis s3.amazonaws.com récupère au moins la moitié d'un canal 1 Gbit).
-Certains fichiers peuvent ne pas télécharger entièrement. Vérifiez la taille des fichiers et re-télécharger tout ce qui semble douteux.
-
-Certains fichiers peuvent contenir des lignes invalides. Vous pouvez les corriger comme suit:
-
-``` bash
-sed -E '/(.*,){18,}/d' data/yellow_tripdata_2010-02.csv > data/yellow_tripdata_2010-02.csv_
-sed -E '/(.*,){18,}/d' data/yellow_tripdata_2010-03.csv > data/yellow_tripdata_2010-03.csv_
-mv data/yellow_tripdata_2010-02.csv_ data/yellow_tripdata_2010-02.csv
-mv data/yellow_tripdata_2010-03.csv_ data/yellow_tripdata_2010-03.csv
-```
-
-Ensuite, les données doivent être pré-traitées dans PostgreSQL. Cela créera des sélections de points dans les polygones (pour faire correspondre les points sur la carte avec les arrondissements de New York) et combinera toutes les données en une seule table plate dénormalisée à l'aide d'une jointure. Pour ce faire, vous devrez installer PostgreSQL avec le support PostGIS.
-
-Soyez prudent lors de l'exécution `initialize_database.sh` et vérifiez à nouveau manuellement que toutes les tables ont été créées correctement.
-
-Il faut environ 20-30 minutes pour traiter la valeur de chaque mois de données dans PostgreSQL, pour un total d'environ 48 heures.
-
-Vous pouvez vérifier le nombre de téléchargé lignes comme suit:
-
-``` bash
-$ time psql nyc-taxi-data -c "SELECT count(*) FROM trips;"
-## Count
- 1298979494
-(1 row)
-
-real    7m9.164s
-```
-
-(C'est un peu plus de 1,1 milliard de lignes rapportées par Mark Litwintschik dans une série de billets de blog.)
-
-Les données de PostgreSQL utilisent 370 GO d'espace.

-
-Dans ce cas, le temps de traitement des requêtes est déterminé surtout par la latence du réseau.
-Nous avons exécuté des requêtes en utilisant un client situé dans un centre de données Yandex en Finlande sur un cluster en Russie, ce qui a ajouté environ 20 ms de latence.

----
-
-# Installation {#installation}
-
-## Configuration Système Requise {#system-requirements}
-
-ClickHouse peut fonctionner sur N'importe quel Linux, FreeBSD ou Mac OS X avec une architecture CPU x86_64, AArch64 ou PowerPC64LE.
-
-Les binaires pré-construits officiels sont généralement compilés pour le jeu d'instructions x86_64 et leverage SSE 4.2, donc sauf indication contraire, l'utilisation du processeur qui le prend en charge devient une exigence système supplémentaire. Voici la commande pour vérifier si le processeur actuel prend en charge SSE 4.2:
-
-``` bash
-$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
-```
-
-Pour exécuter ClickHouse sur des processeurs qui ne prennent pas en charge SSE 4.2 ou qui ont une architecture AArch64 ou PowerPC64LE, vous devez [construire ClickHouse à partir de sources](#from-sources) avec des ajustements de configuration appropriés.
-
-## Options D'Installation Disponibles {#available-installation-options}
-
-### À partir de paquets DEB {#install-from-deb-packages}
-
-Il est recommandé d'utiliser officiel pré-compilé `deb` Paquets Pour Debian ou Ubuntu. Exécutez ces commandes pour installer les paquets:
-
-``` bash
-{% include 'install/deb.sh' %}
-```
-
-Si vous souhaitez utiliser la version la plus récente, remplacer `stable` avec `testing` (ceci est recommandé pour vos environnements de test).
-
-Vous pouvez également télécharger et installer des paquets manuellement à partir de [ici](https://repo.clickhouse.tech/deb/stable/main/).
-
-#### Paquet {#packages}
-
--   `clickhouse-common-static` — Installs ClickHouse compiled binary files.
--   `clickhouse-server` — Creates a symbolic link for `clickhouse-server` et installe la configuration du serveur par défaut.
--   `clickhouse-client` — Creates a symbolic link for `clickhouse-client` et d'autres outils. et installe les fichiers de configuration du client.
--   `clickhouse-common-static-dbg` — Installs ClickHouse compiled binary files with debug info.
-
-### À partir de paquets RPM {#from-rpm-packages}
-
-Il est recommandé d'utiliser officiel pré-compilé `rpm` packages pour CentOS, RedHat et toutes les autres distributions Linux basées sur rpm.
-
-Tout d'abord, vous devez ajouter le dépôt officiel:
-
-``` bash
-sudo yum install yum-utils
-sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
-sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64
-```
-
-Si vous souhaitez utiliser la version la plus récente, remplacer `stable` avec `testing` (ceci est recommandé pour vos environnements de test). Le `prestable` la balise est parfois trop.
-
-Exécutez ensuite ces commandes pour installer les paquets:
-
-``` bash
-sudo yum install clickhouse-server clickhouse-client
-```
-
-Vous pouvez également télécharger et installer des paquets manuellement à partir de [ici](https://repo.clickhouse.tech/rpm/stable/x86_64).
-
-### À Partir D'Archives Tgz {#from-tgz-archives}
-
-Il est recommandé d'utiliser officiel pré-compilé `tgz` archives pour toutes les distributions Linux, où l'installation de `deb` ou `rpm` les emballages n'est pas possible.
-
-La version requise peut être téléchargée avec `curl` ou `wget` depuis le référentiel https://repo.clickhouse.tech/tgz/.
-Après cela, les archives téléchargées doivent être décompressées et installées avec des scripts d'installation. Exemple pour la dernière version:
-
-``` bash
-export LATEST_VERSION=`curl https://api.github.com/repos/ClickHouse/ClickHouse/tags 2>/dev/null | grep -Eo '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | head -n 1`
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-common-static-$LATEST_VERSION.tgz
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-common-static-dbg-$LATEST_VERSION.tgz
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-server-$LATEST_VERSION.tgz
-curl -O https://repo.clickhouse.tech/tgz/clickhouse-client-$LATEST_VERSION.tgz
-
-tar -xzvf clickhouse-common-static-$LATEST_VERSION.tgz
-sudo clickhouse-common-static-$LATEST_VERSION/install/doinst.sh
-
-tar -xzvf clickhouse-common-static-dbg-$LATEST_VERSION.tgz
-sudo clickhouse-common-static-dbg-$LATEST_VERSION/install/doinst.sh
-
-tar -xzvf clickhouse-server-$LATEST_VERSION.tgz
-sudo clickhouse-server-$LATEST_VERSION/install/doinst.sh
-sudo /etc/init.d/clickhouse-server start
-
-tar -xzvf clickhouse-client-$LATEST_VERSION.tgz
-sudo clickhouse-client-$LATEST_VERSION/install/doinst.sh
-```
-
-Pour les environnements de production, il est recommandé d'utiliser la dernière `stable`-version. Vous pouvez trouver son numéro sur la page GitHub https://github.com/ClickHouse/ClickHouse/tags avec postfix `-stable`.
-
-### À Partir De L'Image Docker {#from-docker-image}
-
-Pour exécuter Clickhouse à L'intérieur Docker suivez le guide sur [Hub Docker](https://hub.docker.com/r/yandex/clickhouse-server/). Ces images utilisent officiel `deb` les paquets à l'intérieur.
-
-### À Partir De Sources {#from-sources}
-
-Pour compiler manuellement ClickHouse, suivez les instructions pour [Linux](../development/build.md) ou [Mac OS X](../development/build-osx.md).
-
-Vous pouvez compiler des paquets et les installer ou utiliser des programmes sans installer de paquets. En outre, en construisant manuellement, vous pouvez désactiver L'exigence SSE 4.2 ou construire pour les processeurs AArch64.
-
-      Client: programs/clickhouse-client
-      Server: programs/clickhouse-server
-
-Vous devrez créer un dossier de données et de métadonnées et `chown` pour l'utilisateur souhaité. Leurs chemins peuvent être modifiés dans la configuration du serveur (src / programs / server / config.xml), par défaut, ils sont:
-
-      /opt/clickhouse/data/default/
-      /opt/clickhouse/metadata/default/
-
-Sur Gentoo, vous pouvez simplement utiliser `emerge clickhouse` pour installer ClickHouse à partir de sources.
-
-## Lancer {#launch}
-
-Pour démarrer le serveur en tant que démon, exécutez:
-
-``` bash
-$ sudo service clickhouse-server start
-```
-
-Si vous n'avez pas `service` commande, exécuter comme
-
-``` bash
-$ sudo /etc/init.d/clickhouse-server start
-```
-
-Voir les journaux dans le `/var/log/clickhouse-server/` répertoire.
-
-Si le serveur ne démarre pas, vérifiez les configurations dans le fichier `/etc/clickhouse-server/config.xml`.
-
-Vous pouvez également lancer manuellement le serveur à partir de la console:
-
-``` bash
-$ clickhouse-server --config-file=/etc/clickhouse-server/config.xml
-```
-
-Dans ce cas, le journal sera imprimé sur la console, ce qui est pratique lors du développement.
-Si le fichier de configuration se trouve dans le répertoire courant, vous n'avez pas besoin `--config-file` paramètre. Par défaut, il utilise `./config.xml`.
-
-ClickHouse prend en charge les paramètres de restriction d'accès. Ils sont situés dans la `users.xml` fichier (à côté de `config.xml`).
-Par défaut, l'accès est autorisé depuis n'importe où pour `default` l'utilisateur, sans un mot de passe. Voir `user/default/networks`.
-Pour plus d'informations, consultez la section [“Configuration Files”](../operations/configuration-files.md).
-
-Après le lancement du serveur, vous pouvez utiliser le client de ligne de commande pour vous y connecter:
-
-``` bash
-$ clickhouse-client
-```
-
-Par défaut, il se connecte à `localhost:9000` au nom de l'utilisateur `default` sans un mot de passe. Il peut également être utilisé pour se connecter à un serveur distant en utilisant `--host` argument.
-
-Le terminal doit utiliser L'encodage UTF-8.
-Pour plus d'informations, consultez la section [“Command-line client”](../interfaces/cli.md).
-
-Exemple:
-
-``` bash
-$ ./clickhouse-client
-ClickHouse client version 0.0.18749.
-Connecting to localhost:9000.
-Connected to ClickHouse server version 0.0.18749.
-
-:) SELECT 1
-
-SELECT 1
-
-┌─1─┐
-│ 1 │
-└───┘
-
-1 rows in set. Elapsed: 0.003 sec.
-
-:)
-```
-
-**Félicitations, le système fonctionne!**
-
-Pour continuer à expérimenter, vous pouvez télécharger l'un des jeux de données de test ou passer par [tutoriel](https://clickhouse.tech/tutorial.html).

-# Clickhouse Aire De Jeux {#clickhouse-playground}
-
-[Clickhouse Aire De Jeux](https://play.clickhouse.tech?file=welcome) permet aux utilisateurs d'expérimenter avec ClickHouse en exécutant des requêtes instantanément, sans configurer leur serveur ou leur cluster.
-Plusieurs exemples de jeux de données sont disponibles dans le terrain de jeu ainsi que des exemples de requêtes qui montrent les fonctionnalités de ClickHouse.
-
-Les requêtes sont exécutées comme un utilisateur en lecture seule. Cela implique certaines limites:
-
--   Les requêtes DDL ne sont pas autorisées
--   Les requêtes D'insertion ne sont pas autorisées
-
-Les paramètres suivants sont également appliquées:
-- [`max_result_bytes=10485760`](../operations/settings/query_complexity/#max-result-bytes)
-- [`max_result_rows=2000`](../operations/settings/query_complexity/#setting-max_result_rows)
-- [`result_overflow_mode=break`](../operations/settings/query_complexity/#result-overflow-mode)
-- [`max_execution_time=60000`](../operations/settings/query_complexity/#max-execution-time)

-Clickhouse Playground donne l'expérience du m2.Petite
-[Service géré pour ClickHouse](https://cloud.yandex.com/services/managed-clickhouse)
-exemple hébergé dans [Yandex.Nuage](https://cloud.yandex.com/).
-Plus d'informations sur [les fournisseurs de cloud](../commercial/cloud.md).
-
-Clickhouse Playground interface web fait des demandes via ClickHouse [HTTP API](../interfaces/http.md).
-Le backend Playground est juste un cluster ClickHouse sans aucune application Côté Serveur supplémentaire.
-ClickHouse HTTPS endpoint est également disponible dans le cadre du terrain de jeu.
-
-Vous pouvez effectuer des requêtes sur playground en utilisant n'importe quel client HTTP, par exemple [curl](https://curl.haxx.se) ou [wget](https://www.gnu.org/software/wget/), ou configurer une connexion en utilisant [JDBC](../interfaces/jdbc.md) ou [ODBC](../interfaces/odbc.md) pilote.

-# Tutoriel ClickHouse {#clickhouse-tutorial}
-
-## À quoi S'attendre de ce tutoriel? {#what-to-expect-from-this-tutorial}
-
-En parcourant ce tutoriel, vous apprendrez à configurer un cluster ClickHouse simple. Ce sera petit, mais tolérant aux pannes et évolutif. Ensuite, nous utiliserons l'un des exemples de jeux de données pour le remplir de données et exécuter des requêtes de démonstration.
-
-## Configuration De Noeud Unique {#single-node-setup}
-
-Pour retarder les complexités d'un environnement distribué, nous allons commencer par déployer ClickHouse sur un seul serveur ou une machine virtuelle. ClickHouse est généralement installé à partir de [deb](install.md#install-from-deb-packages) ou [tr / min](install.md#from-rpm-packages) les paquets, mais il y a [alternative](install.md#from-docker-image) pour les systèmes d'exploitation qui ne sont pas les soutenir.
-
-Par exemple, vous avez choisi `deb` paquets et exécutés:
-
-``` bash
-{% include 'install/deb.sh' %}
-```
-
-Quelles sont les paquets installés:
-
--   `clickhouse-client` package contient [clickhouse-client](../interfaces/cli.md) application, client interactif de console de ClickHouse.
--   `clickhouse-common` paquet contient un fichier exécutable ClickHouse.
--   `clickhouse-server` package contient des fichiers de configuration pour exécuter ClickHouse en tant que serveur.
-
-Les fichiers de configuration du serveur sont `/etc/clickhouse-server/`. Avant d'aller plus loin, notez le `<path>` élément `config.xml`. Path détermine l'emplacement pour le stockage des données, il doit donc être situé sur le volume avec une grande capacité de disque; la valeur par défaut est `/var/lib/clickhouse/`. Si vous souhaitez ajuster la configuration, il n'est pas pratique de modifier directement `config.xml` fichier, considérant qu'il pourrait obtenir réécrit sur les futures mises à jour du progiciel. La façon recommandée de remplacer les éléments de configuration est de créer [fichiers dans config.d: répertoire](../operations/configuration-files.md) qui servent de “patches” config.XML.
-
-Comme vous l'avez peut-être remarqué, `clickhouse-server` n'est pas lancé automatiquement après l'installation du paquet. Il ne sera pas redémarré automatiquement après les mises à jour, non plus. La façon dont vous démarrez le serveur dépend de votre système d'initialisation, généralement, c'est:
-
-``` bash
-sudo service clickhouse-server start
-```
-
-ou
-
-``` bash
-sudo /etc/init.d/clickhouse-server start
-```
-
-L'emplacement par défaut pour les journaux du serveur est `/var/log/clickhouse-server/`. Le serveur est prêt à gérer les connexions client une fois `Ready for connections` message.
-
-Une fois l' `clickhouse-server` est opérationnel, nous pouvons utiliser `clickhouse-client` pour se connecter au serveur et effectuer des tests de requêtes comme `SELECT "Hello, world!";`.
-
-<details markdown="1">
-
-<summary>Conseils rapides pour clickhouse-client</summary>
-
-Mode interactif:
-
-``` bash
-clickhouse-client
-clickhouse-client --host=... --port=... --user=... --password=...
-```
-
-Activer les requêtes multilignes:
-
-``` bash
-clickhouse-client -m
-clickhouse-client --multiline
-```
-
-Exécuter des requêtes en mode batch:
-
-``` bash
-clickhouse-client --query='SELECT 1'
-echo 'SELECT 1' | clickhouse-client
-clickhouse-client <<< 'SELECT 1'
-```
-
-Insérer des données à partir d'un fichier au format spécifié:
-
-``` bash
-clickhouse-client --query='INSERT INTO table VALUES' < data.txt
-clickhouse-client --query='INSERT INTO table FORMAT TabSeparated' < data.tsv
-```
-
-</details>
-
-## Importer Un Échantillon De Données {#import-sample-dataset}
-
-Maintenant, il est temps de remplir notre serveur ClickHouse avec quelques exemples de données. Dans ce tutoriel, nous allons utiliser les données anonymisées de Yandex.Metrica, le premier service qui exécute ClickHouse en production avant de devenir open-source (plus à ce sujet dans [section d'histoire](../introduction/history.md)). Il y a [plusieurs façons d'importer Yandex.Metrica dataset](example-datasets/metrica.md), et pour le bien du tutoriel, nous irons avec le plus réaliste.
-
-### Télécharger et extraire les données de la Table {#download-and-extract-table-data}
-
-``` bash
-curl https://datasets.clickhouse.tech/hits/tsv/hits_v1.tsv.xz | unxz --threads=`nproc` > hits_v1.tsv
-curl https://datasets.clickhouse.tech/visits/tsv/visits_v1.tsv.xz | unxz --threads=`nproc` > visits_v1.tsv
-```
-
-Les fichiers extraits ont une taille d'environ 10 Go.
-
-### Créer Des Tables {#create-tables}
-
-Comme dans la plupart des systèmes de gestion de bases de données, clickhouse regroupe logiquement les tables en “databases”. Il y a un `default` base de données, mais nous allons en créer une nouvelle nommée `tutorial`:
-
-``` bash
-clickhouse-client --query "CREATE DATABASE IF NOT EXISTS tutorial"
-```
-
-La syntaxe pour créer des tables est beaucoup plus compliquée par rapport aux bases de données (voir [référence](../sql-reference/statements/create.md). En général `CREATE TABLE` déclaration doit spécifier trois choses clés:
-
-1.  Nom de la table à créer.
-2.  Table schema, i.e. list of columns and their [types de données](../sql-reference/data-types/index.md).
-3.  [Tableau moteur](../engines/table-engines/index.md) et ses paramètres, qui détermine tous les détails sur la façon dont les requêtes à cette table seront physiquement exécutées.
-
-Yandex.Metrica est un service d'analyse web, et l'exemple de jeu de données ne couvre pas toutes ses fonctionnalités, il n'y a donc que deux tables à créer:
-
--   `hits` est un tableau avec chaque action effectuée par tous les utilisateurs sur tous les sites couverts par le service.
--   `visits` est une table qui contient des sessions pré-construites au lieu d'actions individuelles.
-
-Voyons et exécutons les vraies requêtes create table pour ces tables:

-```
-
-Vous pouvez exécuter ces requêtes en utilisant le mode interactif de `clickhouse-client` (lancez - le simplement dans un terminal sans spécifier une requête à l'avance) ou essayez-en [interface de rechange](../interfaces/index.md) Si tu veux.
-
-Comme nous pouvons le voir, `hits_v1` utilise la [moteur MergeTree de base](../engines/table-engines/mergetree-family/mergetree.md) tandis que le `visits_v1` utilise la [Effondrer](../engines/table-engines/mergetree-family/collapsingmergetree.md) variante.
-
-### Importer Des Données {#import-data}
-
-L'importation de données vers ClickHouse se fait via [INSERT INTO](../sql-reference/statements/insert-into.md) requête comme dans de nombreuses autres bases de données SQL. Toutefois, les données sont généralement fournies dans l'une des [formats de sérialisation pris en charge](../interfaces/formats.md) plutôt `VALUES` clause (qui est également pris en charge).
-
-Les fichiers que nous avons téléchargés plus tôt sont au format séparé par des onglets, alors voici comment les importer via le client console:
-
-``` bash
-clickhouse-client --query "INSERT INTO tutorial.hits_v1 FORMAT TSV" --max_insert_block_size=100000 < hits_v1.tsv
-clickhouse-client --query "INSERT INTO tutorial.visits_v1 FORMAT TSV" --max_insert_block_size=100000 < visits_v1.tsv
-```
-
-ClickHouse a beaucoup de [les paramètres de tune](../operations/settings/index.md) et une façon de Les spécifier dans le client console est via des arguments, comme nous pouvons le voir avec `--max_insert_block_size`. La façon la plus simple de comprendre quels paramètres sont disponibles, que signifient-ils et quelles sont les valeurs par défaut est d'interroger le `system.settings` table:
-
-``` sql
-SELECT name, value, changed, description
-FROM system.settings
-WHERE name LIKE '%max_insert_b%'
-FORMAT TSV
-
-max_insert_block_size    1048576    0    "The maximum block size for insertion, if we control the creation of blocks for insertion."
-```
-
-Optionnellement, vous pouvez [OPTIMIZE](../sql-reference/statements/misc.md#misc_operations-optimize) les tables après l'importation. Les Tables configurées avec un moteur de MergeTree-family font toujours des fusions de parties de données en arrière-plan pour optimiser le stockage des données (ou au moins vérifier si cela a du sens). Ces requêtes forcent le moteur de table à optimiser le stockage dès maintenant au lieu d'un certain temps plus tard:
-
-``` bash
-clickhouse-client --query "OPTIMIZE TABLE tutorial.hits_v1 FINAL"
-clickhouse-client --query "OPTIMIZE TABLE tutorial.visits_v1 FINAL"
-```
-
-Ces requêtes démarrent une opération intensive D'E/S et de CPU, donc si la table reçoit systématiquement de nouvelles données, il est préférable de la laisser seule et de laisser les fusions s'exécuter en arrière-plan.
-
-Maintenant, nous pouvons vérifier si l'importation de table a réussi:
-
-``` bash
-clickhouse-client --query "SELECT COUNT(*) FROM tutorial.hits_v1"
-clickhouse-client --query "SELECT COUNT(*) FROM tutorial.visits_v1"
-```
-
-## Exemple De Requêtes {#example-queries}
-
-``` sql
-SELECT
-    StartURL AS URL,
-    AVG(Duration) AS AvgDuration
-FROM tutorial.visits_v1
-WHERE StartDate BETWEEN '2014-03-23' AND '2014-03-30'
-GROUP BY URL
-ORDER BY AvgDuration DESC
-LIMIT 10
-```
-
-``` sql
-SELECT
-    sum(Sign) AS visits,
-    sumIf(Sign, has(Goals.ID, 1105530)) AS goal_visits,
-    (100. * goal_visits) / visits AS goal_percent
-FROM tutorial.visits_v1
-WHERE (CounterID = 912887) AND (toYYYYMM(StartDate) = 201403) AND (domain(StartURL) = 'yandex.ru')
-```
-
-## Déploiement De Cluster {#cluster-deployment}
-
-Clickhouse cluster est un cluster homogène. Étapes pour configurer:
-
-1.  Installer clickhouse server sur toutes les machines du cluster
-2.  Configurer les configurations de cluster dans les fichiers de configuration
-3.  Créer des tables locales sur chaque instance
-4.  Créer un [Distribué table](../engines/table-engines/special/distributed.md)
-
-[Distribué table](../engines/table-engines/special/distributed.md) est en fait une sorte de “view” aux tables locales du cluster ClickHouse. SELECT query from a distributed table s'exécute à l'aide des ressources de tous les fragments du cluster. Vous pouvez spécifier des configurations pour plusieurs clusters et créer plusieurs tables distribuées fournissant des vues à différents clusters.
-
-Exemple de configuration pour un cluster avec trois fragments, une réplique chacun:
-
-``` xml
-<remote_servers>
-    <perftest_3shards_1replicas>
-        <shard>
-            <replica>
-                <host>example-perftest01j.yandex.ru</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-        <shard>
-            <replica>
-                <host>example-perftest02j.yandex.ru</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-        <shard>
-            <replica>
-                <host>example-perftest03j.yandex.ru</host>
-                <port>9000</port>
-            </replica>
-        </shard>
-    </perftest_3shards_1replicas>
-</remote_servers>
-```
-
-Pour plus de démonstration, créons une nouvelle table locale avec le même `CREATE TABLE` la requête que nous avons utilisé pour `hits_v1`, mais nom de table différent:
-
-``` sql
-CREATE TABLE tutorial.hits_local (...) ENGINE = MergeTree() ...
-```
-
-Création d'une table distribuée fournissant une vue dans les tables locales du cluster:
-
-``` sql
-CREATE TABLE tutorial.hits_all AS tutorial.hits_local
-ENGINE = Distributed(perftest_3shards_1replicas, tutorial, hits_local, rand());
-```
-
-Une pratique courante consiste à créer des tables distribuées similaires sur toutes les machines du cluster. Il permet d'exécuter des requêtes distribuées sur n'importe quelle machine du cluster. Il existe également une autre option pour créer une table distribuée temporaire pour une requête SELECT donnée en utilisant [distant](../sql-reference/table-functions/remote.md) table de fonction.
-
-Passons à l'exécution de [INSERT SELECT](../sql-reference/statements/insert-into.md) dans les Distribué table la table à plusieurs serveurs.
-
-``` sql
-INSERT INTO tutorial.hits_all SELECT * FROM tutorial.hits_v1;
-```
-
-!!! warning "Avis"
-    Cette approche ne convient pas au sharding de grandes tables. Il y a un outil séparé [clickhouse-copieur](../operations/utilities/clickhouse-copier.md) cela peut re-fragmenter de grandes tables arbitraires.
-
-Comme vous pouvez vous y attendre, les requêtes lourdes de calcul s'exécutent N fois plus vite si elles utilisent 3 serveurs au lieu d'un.
-
-Dans ce cas, nous avons utilisé un cluster avec 3 fragments, et chacun contient une seule réplique.
-
-Pour assurer la résilience dans un environnement de production, nous recommandons que chaque fragment contienne 2-3 répliques réparties entre plusieurs zones de disponibilité ou centres de données (ou au moins des racks). Notez que ClickHouse prend en charge un nombre illimité de répliques.
-
-Exemple de configuration pour un cluster d'un fragment contenant trois répliques:
-
-``` xml
-<remote_servers>
-    ...
-    <perftest_1shards_3replicas>
-        <shard>
-            <replica>
-                <host>example-perftest01j.yandex.ru</host>
-                <port>9000</port>
-             </replica>
-             <replica>
-                <host>example-perftest02j.yandex.ru</host>
-                <port>9000</port>
-             </replica>
-             <replica>
-                <host>example-perftest03j.yandex.ru</host>
-                <port>9000</port>
-             </replica>
-        </shard>
-    </perftest_1shards_3replicas>
-</remote_servers>
-```
-
-Pour activer la réplication native [ZooKeeper](http://zookeeper.apache.org/) est requis. ClickHouse s'occupe de la cohérence des données sur toutes les répliques et exécute automatiquement la procédure de restauration après l'échec. Il est recommandé de déployer le cluster ZooKeeper sur des serveurs séparés (où aucun autre processus, y compris ClickHouse, n'est en cours d'exécution).
-
-!!! note "Note"
-    ZooKeeper est pas une exigence stricte: dans certains cas simples, vous pouvez dupliquer les données par écrit dans tous les réplicas de votre code d'application. Cette approche est **pas** recommandé, dans ce cas, ClickHouse ne sera pas en mesure de garantir la cohérence des données sur toutes les répliques. Ainsi, il devient la responsabilité de votre application.
-
-Les emplacements ZooKeeper sont spécifiés dans le fichier de configuration:
-
-``` xml
-<zookeeper>
-    <node>
-        <host>zoo01.yandex.ru</host>
-        <port>2181</port>
-    </node>
-    <node>
-        <host>zoo02.yandex.ru</host>
-        <port>2181</port>
-    </node>
-    <node>
-        <host>zoo03.yandex.ru</host>
-        <port>2181</port>
-    </node>
-</zookeeper>
-```
-
-En outre, nous devons définir des macros pour identifier chaque fragment et chaque réplique utilisés lors de la création de la table:
-
-``` xml
-<macros>
-    <shard>01</shard>
-    <replica>01</replica>
-</macros>
-```
-
-S'il n'y a pas de répliques pour le moment lors de la création de la table répliquée, une nouvelle première réplique est instanciée. S'il existe déjà des répliques en direct, la nouvelle réplique clone les données de celles existantes. Vous avez la possibilité de créer toutes les tables répliquées d'abord, et ensuite insérer les données. Une autre option consiste à créer des répliques et à en ajouter d'autres Après ou pendant l'insertion des données.
-
-``` sql
-CREATE TABLE tutorial.hits_replica (...)
-ENGINE = ReplcatedMergeTree(
-    '/clickhouse_perftest/tables/{shard}/hits',
-    '{replica}'
-)
-...
-```
-
-Ici, nous utilisons [ReplicatedMergeTree](../engines/table-engines/mergetree-family/replication.md) tableau moteur. Dans les paramètres, nous spécifions le chemin Zookeeper contenant des identificateurs de fragments et de répliques.
-
-``` sql
-INSERT INTO tutorial.hits_replica SELECT * FROM tutorial.hits_local;
-```
-
-La réplication fonctionne en mode multi-maître. Les données peuvent être chargées dans n'importe quel réplica, et le système les synchronise ensuite automatiquement avec d'autres instances. La réplication est asynchrone, donc à un moment donné, toutes les répliques ne peuvent pas contenir de données récemment insérées. Au moins une réplique devrait être en place pour permettre l'ingestion de données. D'autres synchroniseront les données et répareront la cohérence une fois qu'ils redeviendront actifs. Notez que cette approche permet une faible possibilité de perte de données récemment insérées.

-# Application D'un modèle Catboost dans ClickHouse {#applying-catboost-model-in-clickhouse}
-
-[CatBoost](https://catboost.ai) est une bibliothèque de dynamisation de gradient libre et open-source développée à [Yandex](https://yandex.com/company/) pour l'apprentissage automatique.
-
-Avec cette instruction, vous apprendrez à appliquer des modèles pré-formés dans ClickHouse en exécutant l'inférence de modèle à partir de SQL.
-
-Pour appliquer un modèle CatBoost dans ClickHouse:
-
-1.  [Créer une Table](#create-table).
-2.  [Insérez les données dans la Table](#insert-data-to-table).
-3.  [Intégrer CatBoost dans ClickHouse](#integrate-catboost-into-clickhouse) (Étape facultative).
-4.  [Exécutez L'inférence du modèle à partir de SQL](#run-model-inference).
-
-Pour plus d'informations sur la formation des modèles CatBoost, voir [Formation et application de modèles](https://catboost.ai/docs/features/training.html#training).
-
-## Préalable {#prerequisites}
-
-Si vous n'avez pas le [Docker](https://docs.docker.com/install/) pourtant, l'installer.
-
-!!! note "Note"
-    [Docker](https://www.docker.com) est une plate-forme logicielle qui vous permet de créer des conteneurs qui isolent une installation CatBoost et ClickHouse du reste du système.
-
-Avant d'appliquer un modèle CatBoost:
-
-**1.** Tirez la [Docker image](https://hub.docker.com/r/yandex/tutorial-catboost-clickhouse) à partir du registre:
-
-``` bash
-$ docker pull yandex/tutorial-catboost-clickhouse
-```
-
-Cette image Docker contient tout ce dont vous avez besoin pour exécuter CatBoost et ClickHouse: code, runtime, bibliothèques, variables d'environnement et fichiers de configuration.
-
-**2.** Assurez-vous que l'image Docker a été tirée avec succès:
-
-``` bash
-$ docker image ls
-REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
-yandex/tutorial-catboost-clickhouse   latest              622e4d17945b        22 hours ago        1.37GB
-```
-
-**3.** Démarrer un conteneur Docker basé sur cette image:
-
-``` bash
-$ docker run -it -p 8888:8888 yandex/tutorial-catboost-clickhouse
-```
-
-## 1. Créer une Table {#create-table}
-
-Pour créer une table ClickHouse pour l'exemple de formation:
-
-**1.** Démarrez clickhouse console client en mode interactif:
-
-``` bash
-$ clickhouse client
-```
-
-!!! note "Note"
-    Le serveur ClickHouse est déjà en cours d'exécution dans le conteneur Docker.
-
-**2.** Créer la table à l'aide de la commande:
-
-``` sql
-:) CREATE TABLE amazon_train
-(
-    date Date MATERIALIZED today(),
-    ACTION UInt8,
-    RESOURCE UInt32,
-    MGR_ID UInt32,
-    ROLE_ROLLUP_1 UInt32,
-    ROLE_ROLLUP_2 UInt32,
-    ROLE_DEPTNAME UInt32,
-    ROLE_TITLE UInt32,
-    ROLE_FAMILY_DESC UInt32,
-    ROLE_FAMILY UInt32,
-    ROLE_CODE UInt32
-)
-ENGINE = MergeTree ORDER BY date
-```
-
-**3.** Quitter le client de la console ClickHouse:
-
-``` sql
-:) exit
-```
-
-## 2. Insérez les données dans la Table {#insert-data-to-table}
-
-Pour insérer les données:
-
-**1.** Exécutez la commande suivante:
-
-``` bash
-$ clickhouse client --host 127.0.0.1 --query 'INSERT INTO amazon_train FORMAT CSVWithNames' < ~/amazon/train.csv
-```
-
-**2.** Démarrez clickhouse console client en mode interactif:
-
-``` bash
-$ clickhouse client
-```
-
-**3.** Assurez-vous que les données ont été téléchargées:
-
-``` sql
-:) SELECT count() FROM amazon_train
-
-SELECT count()
-FROM amazon_train
-
-+-count()-+
-|   65538 |
-+-------+
-```
-
-## 3. Intégrer CatBoost dans ClickHouse {#integrate-catboost-into-clickhouse}
-
-!!! note "Note"
-    **Étape facultative.** L'image Docker contient tout ce dont vous avez besoin pour exécuter CatBoost et ClickHouse.
-
-Pour intégrer CatBoost dans ClickHouse:
-
-**1.** Construire la bibliothèque d'évaluation.
-
-Le moyen le plus rapide d'évaluer un modèle CatBoost est la compilation `libcatboostmodel.<so|dll|dylib>` bibliothèque. Pour plus d'informations sur la création de la bibliothèque, voir [Documentation CatBoost](https://catboost.ai/docs/concepts/c-plus-plus-api_dynamic-c-pluplus-wrapper.html).
-
-**2.** Créez un nouveau répertoire n'importe où et avec n'importe quel nom, par exemple, `data` et mettez la bibliothèque créée dedans. L'image Docker contient déjà la bibliothèque `data/libcatboostmodel.so`.
-
-**3.** Créez un nouveau répertoire pour le modèle de configuration n'importe où et avec n'importe quel nom, par exemple, `models`.
-
-**4.** Créez un fichier de configuration de modèle avec n'importe quel nom, par exemple, `models/amazon_model.xml`.
-
-**5.** Décrire la configuration du modèle:
-
-``` xml
-<models>
-    <model>
-        <!-- Model type. Now catboost only. -->
-        <type>catboost</type>
-        <!-- Model name. -->
-        <name>amazon</name>
-        <!-- Path to trained model. -->
-        <path>/home/catboost/tutorial/catboost_model.bin</path>
-        <!-- Update interval. -->
-        <lifetime>0</lifetime>
-    </model>
-</models>
-```
-
-**6.** Ajoutez le chemin D'accès à CatBoost et la configuration du modèle à la configuration de ClickHouse:
-
-``` xml
-<!-- File etc/clickhouse-server/config.d/models_config.xml. -->
-<catboost_dynamic_library_path>/home/catboost/data/libcatboostmodel.so</catboost_dynamic_library_path>
-<models_config>/home/catboost/models/*_model.xml</models_config>
-```
-
-## 4. Exécutez L'inférence du modèle à partir de SQL {#run-model-inference}
-
-Pour le modèle de test exécutez le client ClickHouse `$ clickhouse client`.
-
-Assurons nous que le modèle fonctionne:
-
-``` sql
-:) SELECT
-    modelEvaluate('amazon',
-                RESOURCE,
-                MGR_ID,
-                ROLE_ROLLUP_1,
-                ROLE_ROLLUP_2,
-                ROLE_DEPTNAME,
-                ROLE_TITLE,
-                ROLE_FAMILY_DESC,
-                ROLE_FAMILY,
-                ROLE_CODE) > 0 AS prediction,
-    ACTION AS target
-FROM amazon_train
-LIMIT 10
-```
-
-!!! note "Note"
-    Fonction [modelEvaluate](../sql-reference/functions/other-functions.md#function-modelevaluate) retourne tuple avec des prédictions brutes par classe pour les modèles multiclasse.
-
-Prédisons la probabilité:
-
-``` sql
-:) SELECT
-    modelEvaluate('amazon',
-                RESOURCE,
-                MGR_ID,
-                ROLE_ROLLUP_1,
-                ROLE_ROLLUP_2,
-                ROLE_DEPTNAME,
-                ROLE_TITLE,
-                ROLE_FAMILY_DESC,
-                ROLE_FAMILY,
-                ROLE_CODE) AS prediction,
-    1. / (1 + exp(-prediction)) AS probability,
-    ACTION AS target
-FROM amazon_train
-LIMIT 10
-```
-
-!!! note "Note"
-    Plus d'infos sur [exp()](../sql-reference/functions/math-functions.md) fonction.
-
-Calculons LogLoss sur l'échantillon:
-
-``` sql
-:) SELECT -avg(tg * log(prob) + (1 - tg) * log(1 - prob)) AS logloss
-FROM
-(
-    SELECT
-        modelEvaluate('amazon',
-                    RESOURCE,
-                    MGR_ID,
-                    ROLE_ROLLUP_1,

-# Qu'Est-Ce Que ClickHouse? {#what-is-clickhouse}
-
-ClickHouse est un système de gestion de base de données orienté colonne (SGBD) pour le traitement analytique en ligne des requêtes (OLAP).
-
-Dans un “normal” SGBD orienté ligne, les données sont stockées dans cet ordre:
-
-| Rangée | WatchID     | JavaEnable | Intitulé                         | GoodEvent | EventTime           |
-|--------|-------------|------------|----------------------------------|-----------|---------------------|
-| #0    | 89354350662 | 1          | Relations Avec Les Investisseurs | 1         | 2016-05-18 05:19:20 |
-| #1    | 90329509958 | 0          | Contacter                        | 1         | 2016-05-18 08:10:20 |
-| #2    | 89953706054 | 1          | Mission                          | 1         | 2016-05-18 07:38:00 |
-| #N    | …           | …          | …                                | …         | …                   |
-
-En d'autres termes, toutes les valeurs liées à une ligne sont physiquement stockées l'une à côté de l'autre.
-
-Des exemples d'un SGBD orienté ligne sont MySQL, Postgres et MS SQL Server.
-
-Dans un SGBD orienté colonne, les données sont stockées comme ceci:
-
-| Rangée:     | #0                              | #1                 | #2                 | #N |
-|-------------|----------------------------------|---------------------|---------------------|-----|
-| WatchID:    | 89354350662                      | 90329509958         | 89953706054         | …   |
-| JavaEnable: | 1                                | 0                   | 1                   | …   |
-| Intitulé:   | Relations Avec Les Investisseurs | Contacter           | Mission             | …   |
-| GoodEvent:  | 1                                | 1                   | 1                   | …   |
-| EventTime:  | 2016-05-18 05:19:20              | 2016-05-18 08:10:20 | 2016-05-18 07:38:00 | …   |
-
-Ces exemples montrent l'ordre que les données sont organisées en. Les valeurs de différentes colonnes sont stockés séparément, et les données de la même colonne sont stockées ensemble.
-
-Exemples D'un SGBD orienté colonne: Vertica, Paraccel (matrice Actian et Amazon Redshift), Sybase IQ, Exasol, Infobright, InfiniDB, MonetDB (VectorWise et Actian Vector), LucidDB, SAP HANA, Google Dremel, Google PowerDrill, Druid et kdb+.
-
-Different orders for storing data are better suited to different scenarios. The data access scenario refers to what queries are made, how often, and in what proportion; how much data is read for each type of query – rows, columns, and bytes; the relationship between reading and updating data; the working size of the data and how locally it is used; whether transactions are used, and how isolated they are; requirements for data replication and logical integrity; requirements for latency and throughput for each type of query, and so on.
-
-Plus la charge sur le système est élevée, plus il est important de personnaliser le système configuré pour correspondre aux exigences du scénario d'utilisation, et plus cette personnalisation devient fine. Il n'y a pas de système qui soit aussi bien adapté à des scénarios significativement différents. Si un système est adaptable à un large ensemble de scénarios, sous une charge élevée, le système traitera tous les scénarios de manière également médiocre, ou fonctionnera bien pour un ou quelques-uns des scénarios possibles.
-
-## Propriétés clés du scénario OLAP {#key-properties-of-olap-scenario}
-
--   La grande majorité des demandes concernent l'accès en lecture.
--   Les données sont mises à jour en lots assez importants (\> 1000 lignes), pas par des lignes simples; ou elles ne sont pas mises à jour du tout.
--   Les données sont ajoutées à la base de données mais ne sont pas modifiées.
--   Pour les lectures, un assez grand nombre de lignes sont extraites de la base de données, mais seulement un petit sous-ensemble de colonnes.
--   Les Tables sont “wide,” ce qui signifie qu'ils contiennent un grand nombre de colonnes.
--   Les requêtes sont relativement rares (généralement des centaines de requêtes par serveur ou moins par seconde).
--   Pour les requêtes simples, les latences autour de 50 ms sont autorisées.
--   Les valeurs de colonne sont assez petites: nombres et chaînes courtes (par exemple, 60 octets par URL).
--   Nécessite un débit élevé lors du traitement d'une seule requête (jusqu'à des milliards de lignes par seconde par serveur).
--   Les Transactions ne sont pas nécessaires.
--   Faibles exigences en matière de cohérence des données.
--   Il y a une grande table par requête. Toutes les tables sont petites, sauf une.
--   Un résultat de requête est significativement plus petit que les données source. En d'autres termes, les données sont filtrées ou agrégées, de sorte que le résultat s'intègre dans la RAM d'un seul serveur.
-
-Il est facile de voir que le scénario OLAP est très différent des autres scénarios populaires (tels que OLTP ou key-Value access). Il n'est donc pas logique d'essayer D'utiliser OLTP ou une base de données clé-valeur pour traiter les requêtes analytiques si vous voulez obtenir des performances décentes. Par exemple, si vous essayez D'utiliser MongoDB ou Redis pour l'analyse, vous obtiendrez des performances très médiocres par rapport aux bases de données OLAP.
-
-## Pourquoi les bases de données orientées colonne fonctionnent mieux dans le scénario OLAP {#why-column-oriented-databases-work-better-in-the-olap-scenario}
-
-Les bases de données orientées colonne sont mieux adaptées aux scénarios OLAP: elles sont au moins 100 fois plus rapides dans le traitement de la plupart des requêtes. Les raisons sont expliquées en détail ci-dessous, mais le fait est plus facile de démontrer visuellement:
-
-**SGBD orienté ligne**
-
-![Row-oriented](images/row-oriented.gif#)
-
-**SGBD orienté colonne**
-
-![Column-oriented](images/column-oriented.gif#)
-
-Vous voyez la différence?
-
-### D'entrée/sortie {#inputoutput}
-
-1.  Pour une requête analytique, seul un petit nombre de colonnes de table doit être lu. Dans une base de données orientée colonne, vous pouvez lire uniquement les données dont vous avez besoin. Par exemple, si vous avez besoin de 5 colonnes sur 100, Vous pouvez vous attendre à une réduction de 20 fois des e / s.
-2.  Puisque les données sont lues en paquets, il est plus facile de les compresser. Les données dans les colonnes sont également plus faciles à compresser. Cela réduit d'autant le volume d'e/S.
-3.  En raison de la réduction des E / S, Plus de données s'insèrent dans le cache du système.
-
-Par exemple, la requête “count the number of records for each advertising platform” nécessite la lecture d'un “advertising platform ID” colonne, qui prend 1 octet non compressé. Si la majeure partie du trafic ne provenait pas de plates-formes publicitaires, vous pouvez vous attendre à une compression d'au moins 10 fois de cette colonne. Lors de l'utilisation d'un algorithme de compression rapide, la décompression des données est possible à une vitesse d'au moins plusieurs gigaoctets de données non compressées par seconde. En d'autres termes, cette requête ne peut être traitée qu'à une vitesse d'environ plusieurs milliards de lignes par seconde sur un seul serveur. Cette vitesse est effectivement atteinte dans la pratique.
-
-### CPU {#cpu}
-
-Étant donné que l'exécution d'une requête nécessite le traitement d'un grand nombre de lignes, il est utile de répartir toutes les opérations pour des vecteurs entiers au lieu de lignes séparées, ou d'implémenter le moteur de requête de sorte qu'il n'y ait presque aucun coût d'expédition. Si vous ne le faites pas, avec un sous-système de disque à moitié décent, l'interpréteur de requête bloque inévitablement le processeur. Il est logique de stocker des données dans des colonnes et de les traiter, si possible, par des colonnes.
-
-Il y a deux façons de le faire:
-
-1.  Un moteur vectoriel. Toutes les opérations sont écrites pour les vecteurs, au lieu de valeurs séparées. Cela signifie que vous n'avez pas besoin d'appeler les opérations très souvent, et les coûts d'expédition sont négligeables. Le code d'opération contient un cycle interne optimisé.
-
-2.  La génération de Code. Le code généré pour la requête contient tous les appels indirects.
-
-Ce n'est pas fait dans “normal” bases de données, car cela n'a pas de sens lors de l'exécution de requêtes simples. Cependant, il y a des exceptions. Par exemple, MemSQL utilise la génération de code pour réduire la latence lors du traitement des requêtes SQL. (À titre de comparaison, les SGBD analytiques nécessitent une optimisation du débit, et non une latence.)
-
-Notez que pour l'efficacité du processeur, le langage de requête doit être déclaratif (SQL ou MDX), ou au moins un vecteur (J, K). La requête ne doit contenir que des boucles implicites, permettant une optimisation.

-toc_title: Client De Ligne De Commande
----
-
-# Client de ligne de commande {#command-line-client}
-
-ClickHouse fournit un client de ligne de commande natif: `clickhouse-client`. Le client prend en charge les options de ligne de commande et les fichiers de configuration. Pour plus d'informations, voir [Configuration](#interfaces_cli_configuration).
-
-[Installer](../getting-started/index.md) à partir de la `clickhouse-client` package et l'exécuter avec la commande `clickhouse-client`.
-
-``` bash
-$ clickhouse-client
-ClickHouse client version 19.17.1.1579 (official build).
-Connecting to localhost:9000 as user default.
-Connected to ClickHouse server version 19.17.1 revision 54428.
-
-:)
-```
-
-Différentes versions client et serveur sont compatibles les unes avec les autres, mais certaines fonctionnalités peuvent ne pas être disponibles dans les anciens clients. Nous vous recommandons d'utiliser la même version du client que l'application serveur. Lorsque vous essayez d'utiliser un client de l'ancienne version, puis le serveur, `clickhouse-client` affiche le message:
-
-      ClickHouse client version is older than ClickHouse server. It may lack support for new features.
-
-## Utilisation {#cli_usage}
-
-Le client peut être utilisé en mode interactif et non interactif (batch). Pour utiliser le mode batch, spécifiez ‘query’ d'un paramètre ou d'envoyer des données à ‘stdin’ (il vérifie que ‘stdin’ n'est pas un terminal), ou les deux. Similaire à L'interface HTTP, lors de l'utilisation ‘query’ paramètre et envoi de données à ‘stdin’ la demande est une concaténation de la ‘query’ paramètre, un saut de ligne, et les données de ‘stdin’. Ceci est pratique pour les grandes requêtes D'insertion.
-
-Exemple d'utilisation du client pour insérer des données:
-
-``` bash
-$ echo -ne "1, 'some text', '2016-08-14 00:00:00'\n2, 'some more text', '2016-08-14 00:00:01'" | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
-
-$ cat <<_EOF | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
-3, 'some text', '2016-08-14 00:00:00'
-4, 'some more text', '2016-08-14 00:00:01'
-_EOF
-
-$ cat file.csv | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
-```
-
-En mode batch, le format de données par défaut est TabSeparated. Vous pouvez définir le format dans la clause FORMAT de la requête.
-
-Par défaut, vous ne pouvez traiter une seule requête en mode batch. De faire plusieurs requêtes à partir d'un “script,” l'utilisation de la `--multiquery` paramètre. Cela fonctionne pour toutes les requêtes sauf INSERT. Les résultats de la requête sont produits consécutivement sans séparateurs supplémentaires. De même, pour traiter un grand nombre de requêtes, vous pouvez exécuter ‘clickhouse-client’ pour chaque requête. Notez que cela peut prendre des dizaines de millisecondes pour lancer le ‘clickhouse-client’ programme.
-
-En mode interactif, vous obtenez une ligne de commande où vous pouvez entrer des requêtes.
-
-Si ‘multiline’ n'est pas spécifié (par défaut): Pour exécuter la requête, appuyez sur Entrée. Le point-virgule n'est pas nécessaire à la fin de la requête. Pour entrer une requête multiligne, entrez une barre oblique inverse `\` avant le saut de ligne. Après avoir appuyé sur Entrée, il vous sera demandé d'entrer la ligne suivante de la requête.
-
-Si multiline est spécifié: pour exécuter une requête, terminez-la par un point-virgule et appuyez sur Entrée. Si le point-virgule a été omis à la fin de l'entrée ligne, vous serez invité à entrer la ligne suivante de la requête.
-
-Une seule requête est exécutée, donc tout après le point-virgule est ignoré.
-
-Vous pouvez spécifier `\G` au lieu de le ou après le point-virgule. Cela indique le format Vertical. Dans ce format, chaque valeur est imprimée sur une ligne distincte, ce qui est pratique pour les grandes tables. Cette fonctionnalité inhabituelle a été ajoutée pour la compatibilité avec la CLI MySQL.
-
-La ligne de commande est basé sur ‘replxx’ (similaire à ‘readline’). En d'autres termes, il utilise les raccourcis clavier familiers et conserve un historique. L'histoire est écrite à `~/.clickhouse-client-history`.
-
-Par défaut, le format utilisé est Jolicompact. Vous pouvez modifier le format dans la clause FORMAT de la requête, ou en spécifiant `\G` à la fin de la requête, en utilisant le `--format` ou `--vertical` dans la ligne de commande, ou en utilisant le fichier de configuration client.
-
-Pour quitter le client, appuyez sur Ctrl + D (ou Ctrl + C), ou entrez l'une des options suivantes au lieu d'une requête: “exit”, “quit”, “logout”, “exit;”, “quit;”, “logout;”, “q”, “Q”, “:q”
-
-Lors du traitement d'une requête, le client affiche:
-
-1.  Progrès, qui est mis à jour pas plus de 10 fois par seconde (par défaut). Pour les requêtes rapides, la progression peut ne pas avoir le temps d'être affichée.
-2.  La requête formatée après l'analyse, pour le débogage.
-3.  Le résultat dans le format spécifié.
-4.  Le nombre de lignes dans le résultat, le temps passé et la vitesse moyenne de traitement des requêtes.
-
-Vous pouvez annuler une requête longue en appuyant sur Ctrl + C. Cependant, vous devrez toujours attendre un peu pour que le serveur abandonne la requête. Il n'est pas possible d'annuler une requête à certaines étapes. Si vous n'attendez pas et appuyez une seconde fois sur Ctrl+C, le client quittera.
-
-Le client de ligne de commande permet de passer des données externes (tables temporaires externes) pour l'interrogation. Pour plus d'informations, consultez la section “External data for query processing”.
-
-### Requêtes avec paramètres {#cli-queries-with-parameters}
-
-Vous pouvez créer une requête avec des paramètres et leur transmettre des valeurs à partir de l'application cliente. Cela permet d'éviter le formatage de la requête avec des valeurs dynamiques spécifiques côté client. Exemple:
-
-``` bash
-$ clickhouse-client --param_parName="[1, 2]"  -q "SELECT * FROM table WHERE a = {parName:Array(UInt16)}"
-```
-
-#### La Syntaxe De La Requête {#cli-queries-with-parameters-syntax}
-
-Formatez une requête comme d'habitude, puis placez les valeurs que vous souhaitez transmettre des paramètres de l'application à la requête entre accolades au format suivant:
-
-``` sql
-{<name>:<data type>}
-```
-
--   `name` — Placeholder identifier. In the console client it should be used in app parameters as `--param_<name> = value`.
--   `data type` — [Type de données](../sql-reference/data-types/index.md) de l'application valeur de paramètre. Par exemple, une structure de données comme `(integer, ('string', integer))` peut avoir la `Tuple(UInt8, Tuple(String, UInt8))` type de données (vous pouvez également utiliser un autre [entier](../sql-reference/data-types/int-uint.md) type).
-
-#### Exemple {#example}
-
-``` bash
-$ clickhouse-client --param_tuple_in_tuple="(10, ('dt', 10))" -q "SELECT * FROM table WHERE val = {tuple_in_tuple:Tuple(UInt8, Tuple(String, UInt8))}"
-```
-
-## Configuration {#interfaces_cli_configuration}
-
-Vous pouvez passer des paramètres à `clickhouse-client` (tous les paramètres ont une valeur par défaut) en utilisant:
-
--   À partir de la ligne de commande
-
-    Les options de ligne de commande remplacent les valeurs et les paramètres par défaut dans les fichiers de configuration.
-
--   Les fichiers de Configuration.
-
-    Les paramètres des fichiers de configuration remplacent les valeurs par défaut.
-
-### Options De Ligne De Commande {#command-line-options}
-
--   `--host, -h` -– The server name, ‘localhost’ par défaut. Vous pouvez utiliser le nom ou L'adresse IPv4 ou IPv6.
--   `--port` – The port to connect to. Default value: 9000. Note that the HTTP interface and the native interface use different ports.
--   `--user, -u` – The username. Default value: default.
--   `--password` – The password. Default value: empty string.
--   `--query, -q` – The query to process when using non-interactive mode.
--   `--database, -d` – Select the current default database. Default value: the current database from the server settings (‘default’ par défaut).
--   `--multiline, -m` – If specified, allow multiline queries (do not send the query on Enter).
--   `--multiquery, -n` – If specified, allow processing multiple queries separated by semicolons.
--   `--format, -f` – Use the specified default format to output the result.
--   `--vertical, -E` – If specified, use the Vertical format by default to output the result. This is the same as ‘–format=Vertical’. Dans ce format, chaque valeur est imprimée sur une ligne séparée, ce qui est utile lors de l'affichage de tables larges.
--   `--time, -t` – If specified, print the query execution time to ‘stderr’ en mode non interactif.
--   `--stacktrace` – If specified, also print the stack trace if an exception occurs.
--   `--config-file` – The name of the configuration file.
--   `--secure` – If specified, will connect to server over secure connection.
--   `--param_<name>` — Value for a [requête avec paramètres](#cli-queries-with-parameters).
-
-### Fichiers De Configuration {#configuration_files}
-
-`clickhouse-client` utilise le premier fichier existant de suite:
-
--   Défini dans le `--config-file` paramètre.
--   `./clickhouse-client.xml`
--   `~/.clickhouse-client/config.xml`
--   `/etc/clickhouse-client/config.xml`
-
-Exemple de fichier de configuration:
-
-``` xml
-<config>
-    <user>username</user>
-    <password>password</password>
-    <secure>False</secure>
-</config>
-```

-# Formats pour les données D'entrée et de sortie {#formats}
-
-ClickHouse peut accepter et renvoyer des données dans différents formats. Un format pris en charge pour l'entrée peut être utilisée pour analyser les données fournies à `INSERT`s, pour effectuer `SELECT`s à partir d'une table sauvegardée par fichier, telle Qu'un fichier, une URL ou un HDFS, ou pour lire un dictionnaire externe. Un format pris en charge pour la sortie peut être utilisé pour organiser
-les résultats d'une `SELECT` et pour effectuer `INSERT`s dans une table sauvegardée par fichier.
-
-Les formats pris en charge sont:
-
-| Format                                                          | Entrée | Sortie |

-
-## TabSeparated {#tabseparated}
-
-Au format TabSeparated, les données sont écrites par ligne. Chaque ligne contient des valeurs séparées par des onglets. Chaque valeur est suivie par un onglet, à l'exception de la dernière valeur dans la ligne, qui est suivi par un saut de ligne. Les flux de ligne strictement Unix sont supposés partout. La dernière ligne doit également contenir un saut de ligne à la fin. Les valeurs sont écrites au format texte, sans guillemets et avec des caractères spéciaux échappés.
-
-Ce format est également disponible sous le nom de `TSV`.
-
-Le `TabSeparated` le format est pratique pour le traitement des données à l'aide de programmes et de scripts personnalisés. Il est utilisé par défaut dans L'interface HTTP et dans le mode batch du client de ligne de commande. Ce format permet également de transférer des données entre différents SGBD. Par exemple, vous pouvez obtenir un dump de MySQL et le télécharger sur ClickHouse, ou vice versa.
-
-Le `TabSeparated` format prend en charge la sortie des valeurs totales (lors de L'utilisation avec des totaux) et des valeurs extrêmes (lorsque ‘extremes’ est réglé sur 1). Dans ces cas, les valeurs totales et les extrêmes sont sorties après les données principales. Le résultat principal, les valeurs totales et les extrêmes sont séparés les uns des autres par une ligne vide. Exemple:
-
-``` sql
-SELECT EventDate, count() AS c FROM test.hits GROUP BY EventDate WITH TOTALS ORDER BY EventDate FORMAT TabSeparated``
-```
-
-``` text

-### Mise En Forme Des Données {#data-formatting}
-
-Les nombres entiers sont écrits sous forme décimale. Les numéros peuvent contenir un supplément “+” caractère au début (ignoré lors de l'analyse, et non enregistré lors du formatage). Les nombres non négatifs ne peuvent pas contenir le signe négatif. Lors de la lecture, il est permis d'analyser une chaîne vide en tant que zéro, ou (pour les types signés) une chaîne composée d'un signe moins en tant que zéro. Les nombres qui ne correspondent pas au type de données correspondant peuvent être analysés comme un nombre différent, sans message d'erreur.
-
-Les nombres à virgule flottante sont écrits sous forme décimale. Le point est utilisé comme séparateur décimal. Les entrées exponentielles sont prises en charge, tout comme ‘inf’, ‘+inf’, ‘-inf’, et ‘nan’. Une entrée de nombres à virgule flottante peut commencer ou se terminer par une virgule décimale.
-Pendant le formatage, la précision peut être perdue sur les nombres à virgule flottante.
-Pendant l'analyse, il n'est pas strictement nécessaire de lire le nombre représentable de la machine le plus proche.
-
-Les Dates sont écrites au format AAAA-MM-JJ et analysées dans le même format, mais avec tous les caractères comme séparateurs.
-Les Dates avec les heures sont écrites dans le format `YYYY-MM-DD hh:mm:ss` et analysé dans le même format, mais avec des caractères comme séparateurs.
-Tout cela se produit dans le fuseau horaire du système au moment où le client ou le serveur démarre (selon lequel d'entre eux formate les données). Pour les dates avec des heures, l'heure d'été n'est pas spécifiée. Donc, si un vidage a des temps pendant l'heure d'été, le vidage ne correspond pas sans équivoque aux données, et l'analyse sélectionnera l'une des deux fois.
-Lors d'une opération de lecture, les dates et dates incorrectes avec des heures peuvent être analysées avec un débordement naturel ou en tant que dates et heures nulles, sans message d'erreur.
-
-À titre d'exception, l'analyse des dates avec des heures est également prise en charge au format d'horodatage Unix, si elle se compose exactement de 10 chiffres décimaux. Le résultat n'est pas dépendant du fuseau horaire. Les formats AAAA-MM-JJ hh:mm:ss et NNNNNNNNNN sont différenciés automatiquement.
-
-Les chaînes sont sorties avec des caractères spéciaux échappés par une barre oblique inverse. Les séquences d'échappement suivantes sont utilisées pour la sortie: `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\'`, `\\`. L'analyse prend également en charge les séquences `\a`, `\v`, et `\xHH` (séquences d'échappement hexadécimales) et `\c` séquences, où `c` est un caractère (ces séquences sont convertis à `c`). Ainsi, la lecture de données prend en charge les formats où un saut de ligne peut être écrit comme `\n` ou `\` ou comme un saut de ligne. Par exemple, la chaîne `Hello world` avec un saut de ligne entre les mots au lieu de l'espace peut être analysé dans l'une des variantes suivantes:
-
-``` text
-Hello\nworld
-
-Hello\
-world
-```
-
-La deuxième variante est prise en charge car MySQL l'utilise lors de l'écriture de vidages séparés par des tabulations.
-
-L'ensemble minimum de caractères que vous devez échapper lors du passage de données au format TabSeparated: tab, saut de ligne (LF) et barre oblique inverse.
-
-Seul un petit ensemble de symboles sont échappés. Vous pouvez facilement tomber sur une valeur de chaîne que votre terminal va ruiner en sortie.
-
-Les tableaux sont écrits sous la forme d'une liste de valeurs séparées par des virgules entre crochets. Le nombre d'éléments dans le tableau sont formatés comme normalement. `Date` et `DateTime` les types sont écrits entre guillemets simples. Les chaînes sont écrites entre guillemets simples avec les mêmes règles d'échappement que ci-dessus.
-
-[NULL](../sql-reference/syntax.md) est formaté en tant qu' `\N`.
-
-Chaque élément de [Imbriqué](../sql-reference/data-types/nested-data-structures/nested.md) structures est représenté sous forme de tableau.
-
-Exemple:
-
-``` sql
-CREATE TABLE nestedt
-(
-    `id` UInt8,
-    `aux` Nested(
-        a UInt8,
-        b String
-    )
-)
-ENGINE = TinyLog
-```
-
-``` sql
-INSERT INTO nestedt Values ( 1, [1], ['a'])
-```
-
-``` sql
-SELECT * FROM nestedt FORMAT TSV
-```
-
-``` text
-1  [1]    ['a']
-```
-
-## TabSeparatedRaw {#tabseparatedraw}
-
-Diffère de `TabSeparated` format en ce que les lignes sont écrites sans échappement.
-Ce format n'est approprié que pour la sortie d'un résultat de requête, mais pas pour l'analyse (récupération des données à insérer dans une table).
-
-Ce format est également disponible sous le nom de `TSVRaw`.
-
-## TabSeparatedWithNames {#tabseparatedwithnames}
-
-Diffère de la `TabSeparated` formater en ce que les noms de colonne sont écrits dans la première ligne.
-Pendant l'analyse, la première ligne est complètement ignorée. Vous ne pouvez pas utiliser les noms de colonnes pour déterminer leur position ou vérifier leur exactitude.
-(La prise en charge de l'analyse de la ligne d'en-tête peut être ajoutée à l'avenir.)
-
-Ce format est également disponible sous le nom de `TSVWithNames`.
-
-## TabSeparatedWithNamesAndTypes {#tabseparatedwithnamesandtypes}
-
-Diffère de la `TabSeparated` format que les noms de colonne sont écrits à la première ligne, tandis que les types de colonne sont dans la deuxième rangée.
-Pendant l'analyse, les première et deuxième lignes sont complètement ignorées.
-
-Ce format est également disponible sous le nom de `TSVWithNamesAndTypes`.
-
-## Modèle {#format-template}
-
-Ce format permet de spécifier une chaîne de format personnalisée avec des espaces réservés pour les valeurs avec une règle d'échappement spécifiée.
-
-Il utilise les paramètres `format_template_resultset`, `format_template_row`, `format_template_rows_between_delimiter` and some settings of other formats (e.g. `output_format_json_quote_64bit_integers` lors de l'utilisation de `JSON` s'échapper, voir plus loin)
-
-Paramètre `format_template_row` spécifie le chemin d'accès au fichier, qui contient une chaîne de format pour les lignes avec la syntaxe suivante:
-
-`delimiter_1${column_1:serializeAs_1}delimiter_2${column_2:serializeAs_2} ... delimiter_N`,
-
-où `delimiter_i` est un délimiteur entre les valeurs (`$` symbole peut être échappé comme `$$`),
-`column_i` est un nom ou un index d'une colonne dont les valeurs sont choisies ou inséré (si vide, alors la colonne sera ignoré),
-`serializeAs_i` est une règle d'échappement pour les valeurs de colonne. Les règles d'échappement suivantes sont prises en charge:
-
--   `CSV`, `JSON`, `XML` (de même pour les formats des mêmes noms)
--   `Escaped` (de la même manière à `TSV`)
--   `Quoted` (de la même manière à `Values`)
--   `Raw` (sans s'échapper, de même pour `TSVRaw`)
--   `None` (pas de règle d'échappement, voir plus loin)
-
-Si une règle d'échappement est omise, alors `None` sera utilisé. `XML` et `Raw` sont adaptés uniquement pour la sortie.
-
-Donc, pour la chaîne de format suivante:
-
-      `Search phrase: ${SearchPhrase:Quoted}, count: ${c:Escaped}, ad price: $$${price:JSON};`
-
-les valeurs de `SearchPhrase`, `c` et `price` colonnes, qui sont échappées comme `Quoted`, `Escaped` et `JSON` imprimées (pour sélectionner) ou sera prévu (insert) entre `Search phrase:`, `, count:`, `, ad price: $` et `;` délimiteurs respectivement. Exemple:
-
-`Search phrase: 'bathroom interior design', count: 2166, ad price: $3;`
-
-Le `format_template_rows_between_delimiter` paramètre spécifie délimiteur entre les lignes, qui est imprimé (ou attendu) après chaque ligne, sauf la dernière (`\n` par défaut)
-
-Paramètre `format_template_resultset` spécifie le chemin d'accès au fichier, qui contient une chaîne de format pour resultset. Format string for resultset a la même syntaxe qu'une chaîne de format pour row et permet de spécifier un préfixe, un suffixe et un moyen d'imprimer des informations supplémentaires. Il contient les espaces réservés suivants au lieu des noms de colonnes:
-
--   `data` est les lignes avec des données dans `format_template_row` format, séparés par des `format_template_rows_between_delimiter`. Cet espace doit être le premier espace réservé dans la chaîne de format.
--   `totals` est la ligne avec des valeurs totales dans `format_template_row` format (lors de L'utilisation avec des totaux)
--   `min` est la ligne avec des valeurs minimales dans `format_template_row` format (lorsque les extrêmes sont définis sur 1)
--   `max` est la ligne avec des valeurs maximales en `format_template_row` format (lorsque les extrêmes sont définis sur 1)
--   `rows` le nombre total de lignes de sortie
--   `rows_before_limit` est le nombre minimal de lignes qu'il y aurait eu sans limite. Sortie uniquement si la requête contient LIMIT. Si la requête contient GROUP BY, rows_before_limit_at_least est le nombre exact de lignes qu'il y aurait eu sans limite.
--   `time` est le temps d'exécution de la requête en secondes
--   `rows_read` est le nombre de lignes a été lu
--   `bytes_read` est le nombre d'octets (non compressé) a été lu
-
-Réservé `data`, `totals`, `min` et `max` ne doit pas avoir de règle d'échappement spécifiée (ou `None` doit être spécifié explicitement). Les espaces réservés restants peuvent avoir une règle d'échappement spécifiée.
-Si l' `format_template_resultset` paramètre est une chaîne vide, `${data}` est utilisé comme valeur par défaut.
-Pour insérer des requêtes format permet de sauter certaines colonnes ou certains champs si préfixe ou suffixe (voir Exemple).

-Sélectionnez exemple:
-
-``` sql
-SELECT SearchPhrase, count() AS c FROM test.hits GROUP BY SearchPhrase ORDER BY c DESC LIMIT 5 FORMAT Template SETTINGS
-format_template_resultset = '/some/path/resultset.format', format_template_row = '/some/path/row.format', format_template_rows_between_delimiter = '\n    '

-Insérez exemple:
-
-``` text
-Some header
-Page views: 5, User id: 4324182021466249494, Useless field: hello, Duration: 146, Sign: -1
-Page views: 6, User id: 4324182021466249494, Useless field: world, Duration: 185, Sign: 1
-Total rows: 2
-```
-
-``` sql
-INSERT INTO UserActivity FORMAT Template SETTINGS
-format_template_resultset = '/some/path/resultset.format', format_template_row = '/some/path/row.format'
-```
-
-`/some/path/resultset.format`:
-
-``` text
-Some header\n${data}\nTotal rows: ${:CSV}\n
-```
-
-`/some/path/row.format`:
-
-``` text
-Page views: ${PageViews:CSV}, User id: ${UserID:CSV}, Useless field: ${:CSV}, Duration: ${Duration:CSV}, Sign: ${Sign:CSV}
-```
-
-`PageViews`, `UserID`, `Duration` et `Sign` à l'intérieur des espaces réservés sont des noms de colonnes dans la table. Les valeurs après `Useless field` en rangées et après `\nTotal rows:` dans le suffixe sera ignoré.
-Tous les séparateurs dans les données d'entrée doivent être strictement égal à délimiteurs dans les chaînes de format.
-
-## TemplateIgnoreSpaces {#templateignorespaces}
-
-Ce format est adapté uniquement pour l'entrée.
-Semblable à `Template`, mais ignore les espaces entre les séparateurs et les valeurs dans le flux d'entrée. Toutefois, si les chaînes de format contiennent des espaces, ces caractères seront attendus dans le flux d'entrée. Permet également de spécifier des espaces réservés vides (`${}` ou `${:None}`) pour diviser un délimiteur en parties séparées pour ignorer les espaces entre eux. Ces espaces réservés sont utilisés uniquement pour ignorer les caractères d'espace.
-Il est possible de lire `JSON` l'utilisation de ce format, si les valeurs des colonnes ont le même ordre dans toutes les lignes. Par exemple, la requête suivante peut être utilisée pour insérer des données à partir d'un exemple de format de sortie [JSON](#json):
-
-``` sql
-INSERT INTO table_name FORMAT TemplateIgnoreSpaces SETTINGS
-format_template_resultset = '/some/path/resultset.format', format_template_row = '/some/path/row.format', format_template_rows_between_delimiter = ','
-```
-
-`/some/path/resultset.format`:
-
-``` text
-{${}"meta"${}:${:JSON},${}"data"${}:${}[${data}]${},${}"totals"${}:${:JSON},${}"extremes"${}:${:JSON},${}"rows"${}:${:JSON},${}"rows_before_limit_at_least"${}:${:JSON}${}}
-```
-
-`/some/path/row.format`:
-
-``` text
-{${}"SearchPhrase"${}:${}${phrase:JSON}${},${}"c"${}:${}${cnt:JSON}${}}
-```
-
-## TSKV {#tskv}
-
-Similaire à TabSeparated, mais affiche une valeur au format name = value. Les noms sont échappés de la même manière qu'au format TabSeparated, et le symbole = est également échappé.
-
-``` text
-SearchPhrase=   count()=8267016
-SearchPhrase=bathroom interior design    count()=2166
-SearchPhrase=yandex     count()=1655
-SearchPhrase=2014 spring fashion    count()=1549
-SearchPhrase=freeform photos       count()=1480
-SearchPhrase=angelina jolie    count()=1245
-SearchPhrase=omsk       count()=1112
-SearchPhrase=photos of dog breeds    count()=1091
-SearchPhrase=curtain designs        count()=1064
-SearchPhrase=baku       count()=1000
-```
-
-[NULL](../sql-reference/syntax.md) est formaté en tant qu' `\N`.
-
-``` sql
-SELECT * FROM t_null FORMAT TSKV
-```
-
-``` text
-x=1    y=\N
-```
-
-Quand il y a un grand nombre de petites colonnes, ce format est inefficace, et il n'y a généralement pas de raison de l'utiliser. Néanmoins, ce n'est pas pire que JSONEachRow en termes d'efficacité.
-
-Both data output and parsing are supported in this format. For parsing, any order is supported for the values of different columns. It is acceptable for some values to be omitted – they are treated as equal to their default values. In this case, zeros and blank rows are used as default values. Complex values that could be specified in the table are not supported as defaults.
-
-L'analyse permet la présence du champ supplémentaire `tskv` sans le signe égal ou de valeur. Ce champ est ignoré.
-
-## CSV {#csv}
-
-Format des valeurs séparées par des virgules ([RFC](https://tools.ietf.org/html/rfc4180)).
-
-Lors du formatage, les lignes sont entourées de guillemets doubles. Un guillemet double à l'intérieur d'une chaîne est affiché sous la forme de deux guillemets doubles dans une rangée. Il n'y a pas d'autres règles pour échapper les caractères. Date et date-heure sont entre guillemets. Les nombres sont produits sans guillemets. Les valeurs sont séparées par un caractère délimiteur, qui est `,` par défaut. Le caractère délimiteur est défini dans le paramètre [format_csv_delimiter](../operations/settings/settings.md#settings-format_csv_delimiter). Les lignes sont séparées à L'aide du saut de ligne Unix (LF). Les tableaux sont sérialisés au format CSV comme suit: tout d'abord, le tableau est sérialisé en une chaîne comme au format TabSeparated, puis la chaîne résultante est sortie au format CSV entre guillemets doubles. Les Tuples au format CSV sont sérialisés en tant que colonnes séparées (c'est-à-dire que leur imbrication dans le tuple est perdue).
-
-``` bash
-$ clickhouse-client --format_csv_delimiter="|" --query="INSERT INTO test.csv FORMAT CSV" < data.csv
-```
-
-\*Par défaut, le délimiteur est `,`. Voir la [format_csv_delimiter](../operations/settings/settings.md#settings-format_csv_delimiter) réglage pour plus d'informations.
-
-Lors de l'analyse, toutes les valeurs peuvent être analysés avec ou sans guillemets. Les guillemets doubles et simples sont pris en charge. Les lignes peuvent également être organisées sans guillemets. Dans ce cas, ils sont analysés jusqu'au caractère délimiteur ou au saut de ligne (CR ou LF). En violation de la RFC, lors de l'analyse des lignes sans guillemets, les espaces et les onglets de début et de fin sont ignorés. Pour le saut de ligne, les types Unix (LF), Windows (CR LF) et Mac OS Classic (CR LF) sont tous pris en charge.
-
-Les valeurs d'entrée non cotées vides sont remplacées par des valeurs par défaut pour les colonnes respectives, si
-[input_format_defaults_for_omitted_fields](../operations/settings/settings.md#session_settings-input_format_defaults_for_omitted_fields)
-est activé.
-
-`NULL` est formaté en tant qu' `\N` ou `NULL` ou une chaîne vide non cotée (voir paramètres [input_format_csv_unquoted_null_literal_as_null](../operations/settings/settings.md#settings-input_format_csv_unquoted_null_literal_as_null) et [input_format_defaults_for_omitted_fields](../operations/settings/settings.md#session_settings-input_format_defaults_for_omitted_fields)).
-
-Le format CSV prend en charge la sortie des totaux et des extrêmes de la même manière que `TabSeparated`.
-
-## CSVWithNames {#csvwithnames}
-
-Imprime également la ligne d'en-tête, semblable à `TabSeparatedWithNames`.
-
-## CustomSeparated {#format-customseparated}
-
-Semblable à [Modèle](#format-template), mais il imprime ou lit toutes les colonnes et utilise la règle d'échappement du paramètre `format_custom_escaping_rule` et délimiteurs de paramètres `format_custom_field_delimiter`, `format_custom_row_before_delimiter`, `format_custom_row_after_delimiter`, `format_custom_row_between_delimiter`, `format_custom_result_before_delimiter` et `format_custom_result_after_delimiter`, pas à partir de chaînes de format.
-Il y a aussi `CustomSeparatedIgnoreSpaces` le format, qui est similaire à `TemplateIgnoreSpaces`.
-
-## JSON {#json}
-
-Sorties de données au format JSON. Outre les tables de données, il génère également des noms et des types de colonnes, ainsi que des informations supplémentaires: le nombre total de lignes de sortie et le nombre de lignes qui auraient pu être sorties s'il n'y avait pas de limite. Exemple:
-
-``` sql
-SELECT SearchPhrase, count() AS c FROM test.hits GROUP BY SearchPhrase WITH TOTALS ORDER BY c DESC LIMIT 5 FORMAT JSON
-```
-
-``` json
-{
-        "meta":

-Le JSON est compatible avec JavaScript. Pour ce faire, certains caractères sont en outre échappés: la barre oblique `/` s'est échappée comme l' `\/`; sauts de ligne alternatifs `U+2028` et `U+2029`, qui cassent certains navigateurs, sont échappés comme `\uXXXX`. Les caractères de contrôle ASCII sont échappés: retour arrière, flux de formulaire, saut de ligne, retour chariot et tabulation horizontale sont remplacés par `\b`, `\f`, `\n`, `\r`, `\t` , ainsi que les octets restants dans la plage 00-1F en utilisant `\uXXXX` sequences. Invalid UTF-8 sequences are changed to the replacement character � so the output text will consist of valid UTF-8 sequences. For compatibility with JavaScript, Int64 and UInt64 integers are enclosed in double-quotes by default. To remove the quotes, you can set the configuration parameter [output_format_json_quote_64bit_integers](../operations/settings/settings.md#session_settings-output_format_json_quote_64bit_integers) à 0.
-
-`rows` – The total number of output rows.
-
-`rows_before_limit_at_least` Le nombre minimal de lignes aurait été sans limite. Sortie uniquement si la requête contient LIMIT.
-Si la requête contient GROUP BY, rows_before_limit_at_least est le nombre exact de lignes qu'il y aurait eu sans limite.
-
-`totals` – Total values (when using WITH TOTALS).
-
-`extremes` – Extreme values (when extremes are set to 1).
-
-Ce format n'est approprié que pour la sortie d'un résultat de requête, mais pas pour l'analyse (récupération des données à insérer dans une table).
-
-Supports ClickHouse [NULL](../sql-reference/syntax.md) s'affiche à l'écran `null` dans la sortie JSON.
-
-Voir aussi l' [JSONEachRow](#jsoneachrow) format.
-
-## JSONCompact {#jsoncompact}
-
-Diffère de JSON uniquement en ce que les lignes de données sont sorties dans des tableaux, pas dans des objets.
-
-Exemple:
-
-``` json
-{
-        "meta":
-        [
-                {
-                        "name": "SearchPhrase",
-                        "type": "String"
-                },
-                {
-                        "name": "c",
-                        "type": "UInt64"
-                }
-        ],
-
-        "data":
-        [
-                ["", "8267016"],
-                ["bathroom interior design", "2166"],
-                ["yandex", "1655"],
-                ["fashion trends spring 2014", "1549"],
-                ["freeform photo", "1480"]
-        ],
-
-        "totals": ["","8873898"],
-
-        "extremes":
-        {
-                "min": ["","1480"],
-                "max": ["","8267016"]
-        },
-
-        "rows": 5,
-
-        "rows_before_limit_at_least": 141137
-}
-```
-
-Ce format n'est approprié que pour la sortie d'un résultat de requête, mais pas pour l'analyse (récupération des données à insérer dans une table).
-Voir aussi l' `JSONEachRow` format.
-
-## JSONEachRow {#jsoneachrow}
-
-Lorsque vous utilisez ce format, ClickHouse affiche les lignes en tant qu'objets JSON séparés et délimités par des retours à la ligne, mais les données dans leur ensemble ne sont pas JSON valides.
-
-``` json
-{"SearchPhrase":"curtain designs","count()":"1064"}
-{"SearchPhrase":"baku","count()":"1000"}
-{"SearchPhrase":"","count()":"8267016"}
-```
-
-Lors de l'insertion des données, vous devez fournir un objet JSON distinct pour chaque ligne.
-
-### Insertion De Données {#inserting-data}
-
-``` sql
-INSERT INTO UserActivity FORMAT JSONEachRow {"PageViews":5, "UserID":"4324182021466249494", "Duration":146,"Sign":-1} {"UserID":"4324182021466249494","PageViews":6,"Duration":185,"Sign":1}
-```
-
-Clickhouse permet:
-
--   Toute commande de paires clé-valeur dans l'objet.
--   Omettre certaines valeurs.
-
-ClickHouse ignore les espaces entre les éléments et les virgules après les objets. Vous pouvez passer tous les objets en une seule ligne. Vous n'avez pas à les séparer avec des sauts de ligne.
-
-**Valeurs omises traitement**
-
-Clickhouse remplace les valeurs omises par les valeurs par défaut pour le [types de données](../sql-reference/data-types/index.md).
-
-Si `DEFAULT expr` clickhouse utilise différentes règles de substitution en fonction de [input_format_defaults_for_omitted_fields](../operations/settings/settings.md#session_settings-input_format_defaults_for_omitted_fields) paramètre.
-
-Considérons le tableau suivant:
-
-``` sql
-CREATE TABLE IF NOT EXISTS example_table
-(
-    x UInt32,
-    a DEFAULT x * 2
-) ENGINE = Memory;
-```
-
--   Si `input_format_defaults_for_omitted_fields = 0`, alors la valeur par défaut pour `x` et `a` égal `0` (la valeur par défaut pour le `UInt32` type de données).
--   Si `input_format_defaults_for_omitted_fields = 1`, alors la valeur par défaut pour `x` égal `0` mais la valeur par défaut de `a` égal `x * 2`.
-
-!!! note "Avertissement"
-    Lors de l'insertion de données avec `insert_sample_with_metadata = 1`, ClickHouse consomme plus de ressources de calcul, par rapport à l'insertion avec `insert_sample_with_metadata = 0`.
-
-### La Sélection De Données {#selecting-data}
-
-Envisager l' `UserActivity` table comme un exemple:
-
-``` text
-┌──────────────UserID─┬─PageViews─┬─Duration─┬─Sign─┐
-│ 4324182021466249494 │         5 │      146 │   -1 │
-│ 4324182021466249494 │         6 │      185 │    1 │
-└─────────────────────┴───────────┴──────────┴──────┘
-```
-
-Requête `SELECT * FROM UserActivity FORMAT JSONEachRow` retourner:
-
-``` text
-{"UserID":"4324182021466249494","PageViews":5,"Duration":146,"Sign":-1}
-{"UserID":"4324182021466249494","PageViews":6,"Duration":185,"Sign":1}
-```
-
-Contrairement à l' [JSON](#json) format, il n'y a pas de substitution de séquences UTF-8 non valides. Les valeurs sont échappés de la même manière que pour `JSON`.
-
-!!! note "Note"
-    Tout ensemble d'octets peut être sortie dans les cordes. L'utilisation de la `JSONEachRow` formater si vous êtes sûr que les données de la table peuvent être formatées en tant que JSON sans perdre aucune information.
-
-### Utilisation de Structures imbriquées {#jsoneachrow-nested}
-
-Si vous avez une table avec [Imbriqué](../sql-reference/data-types/nested-data-structures/nested.md) colonnes de type de données, vous pouvez insérer des données JSON avec la même structure. Activer cette fonctionnalité avec le [input_format_import_nested_json](../operations/settings/settings.md#settings-input_format_import_nested_json) paramètre.
-
-Par exemple, considérez le tableau suivant:
-
-``` sql
-CREATE TABLE json_each_row_nested (n Nested (s String, i Int32) ) ENGINE = Memory
-```
-
-Comme vous pouvez le voir dans la `Nested` description du type de données, ClickHouse traite chaque composant de la structure imbriquée comme une colonne distincte (`n.s` et `n.i` pour notre table). Vous pouvez insérer des données de la manière suivante:
-
-``` sql
-INSERT INTO json_each_row_nested FORMAT JSONEachRow {"n.s": ["abc", "def"], "n.i": [1, 23]}
-```
-
-Pour insérer des données en tant qu'objet JSON hiérarchique, définissez [input_format_import_nested_json=1](../operations/settings/settings.md#settings-input_format_import_nested_json).
-
-``` json
-{
-    "n": {
-        "s": ["abc", "def"],
-        "i": [1, 23]
-    }
-}
-```
-
-Sans ce paramètre, ClickHouse lance une exception.
-
-``` sql
-SELECT name, value FROM system.settings WHERE name = 'input_format_import_nested_json'
-```
-
-``` text
-┌─name────────────────────────────┬─value─┐
-│ input_format_import_nested_json │ 0     │
-└─────────────────────────────────┴───────┘
-```
-
-``` sql
-INSERT INTO json_each_row_nested FORMAT JSONEachRow {"n": {"s": ["abc", "def"], "i": [1, 23]}}
-```
-
-``` text
-Code: 117. DB::Exception: Unknown field found while parsing JSONEachRow format: n: (at row 1)
-```
-
-``` sql
-SET input_format_import_nested_json=1
-INSERT INTO json_each_row_nested FORMAT JSONEachRow {"n": {"s": ["abc", "def"], "i": [1, 23]}}
-SELECT * FROM json_each_row_nested
-```
-
-``` text
-┌─n.s───────────┬─n.i────┐
-│ ['abc','def'] │ [1,23] │
-└───────────────┴────────┘
-```
-
-## Natif {#native}
-
-Le format le plus efficace. Les données sont écrites et lues par des blocs au format binaire. Pour chaque bloc, le nombre de lignes, le nombre de colonnes, les noms et types de colonnes et les parties de colonnes de ce bloc sont enregistrés les uns après les autres. En d'autres termes, ce format est “columnar” – it doesn't convert columns to rows. This is the format used in the native interface for interaction between servers, for using the command-line client, and for C++ clients.
-
-Vous pouvez utiliser ce format pour générer rapidement des vidages qui ne peuvent être lus que par le SGBD ClickHouse. Cela n'a pas de sens de travailler avec ce format vous-même.
-
-## NULL {#null}
-
-Rien n'est sortie. Cependant, la requête est traitée et, lors de l'utilisation du client de ligne de commande, les données sont transmises au client. Ceci est utilisé pour les tests, y compris les tests de performance.
-Évidemment, ce format n'est approprié que pour la sortie, pas pour l'analyse.
-
-## Joli {#pretty}
-
-Affiche les données sous forme de tables Unicode-art, en utilisant également des séquences d'échappement ANSI pour définir les couleurs dans le terminal.
-Une grille complète de la table est dessinée, et chaque ligne occupe deux lignes dans le terminal.
-Chaque bloc de résultat est sorti sous la forme d'une table séparée. Ceci est nécessaire pour que les blocs puissent être sortis sans résultats de mise en mémoire tampon (la mise en mémoire tampon serait nécessaire pour pré-calculer la largeur visible de toutes les valeurs).
-
-[NULL](../sql-reference/syntax.md) est sortie `ᴺᵁᴸᴸ`.
-
-Exemple (montré pour le [PrettyCompact](#prettycompact) format):
-
-``` sql
-SELECT * FROM t_null
-```
-
-``` text
-┌─x─┬────y─┐
-│ 1 │ ᴺᵁᴸᴸ │
-└───┴──────┘
-```
-
-Les lignes ne sont pas échappées dans les formats Pretty\*. Exemple est montré pour la [PrettyCompact](#prettycompact) format:
-
-``` sql
-SELECT 'String with \'quotes\' and \t character' AS Escaping_test
-```
-
-``` text
-┌─Escaping_test────────────────────────┐
-│ String with 'quotes' and      character │
-└──────────────────────────────────────┘
-```
-
-Pour éviter de déverser trop de données sur le terminal, seules les 10 000 premières lignes sont imprimées. Si le nombre de lignes est supérieur ou égal à 10 000, le message “Showed first 10 000” est imprimé.
-Ce format n'est approprié que pour la sortie d'un résultat de requête, mais pas pour l'analyse (récupération des données à insérer dans une table).
-
-Le joli format prend en charge la sortie des valeurs totales (lors de L'utilisation avec des totaux) et des extrêmes (lorsque ‘extremes’ est réglé sur 1). Dans ces cas, les valeurs totales et les valeurs extrêmes sont sorties après les données principales, dans des tableaux séparés. Exemple (montré pour le [PrettyCompact](#prettycompact) format):
-
-``` sql
-SELECT EventDate, count() AS c FROM test.hits GROUP BY EventDate WITH TOTALS ORDER BY EventDate FORMAT PrettyCompact
-```
-
-``` text
-┌──EventDate─┬───────c─┐
-│ 2014-03-17 │ 1406958 │
-│ 2014-03-18 │ 1383658 │
-│ 2014-03-19 │ 1405797 │
-│ 2014-03-20 │ 1353623 │
-│ 2014-03-21 │ 1245779 │
-│ 2014-03-22 │ 1031592 │
-│ 2014-03-23 │ 1046491 │
-└────────────┴─────────┘
-
-Totals:
-┌──EventDate─┬───────c─┐
-│ 1970-01-01 │ 8873898 │
-└────────────┴─────────┘
-
-Extremes:
-┌──EventDate─┬───────c─┐
-│ 2014-03-17 │ 1031592 │
-│ 2014-03-23 │ 1406958 │
-└────────────┴─────────┘
-```
-
-## PrettyCompact {#prettycompact}
-
-Diffère de [Joli](#pretty) en ce que la grille est dessinée entre les lignes et le résultat est plus compact.
-Ce format est utilisé par défaut dans le client de ligne de commande en mode interactif.
-
-## PrettyCompactMonoBlock {#prettycompactmonoblock}
-
-Diffère de [PrettyCompact](#prettycompact) dans ce cas, jusqu'à 10 000 lignes sont mises en mémoire tampon, puis sorties en tant que table unique, pas par blocs.
-
-## PrettyNoEscapes {#prettynoescapes}
-
-Diffère de Pretty en ce que les séquences d'échappement ANSI ne sont pas utilisées. Ceci est nécessaire pour afficher ce format dans un navigateur, ainsi que pour utiliser le ‘watch’ utilitaire de ligne de commande.
-
-Exemple:
-
-``` bash
-$ watch -n1 "clickhouse-client --query='SELECT event, value FROM system.events FORMAT PrettyCompactNoEscapes'"
-```
-
-Vous pouvez utiliser L'interface HTTP pour afficher dans le navigateur.
-
-### Joliscompactnoescapes {#prettycompactnoescapes}
-
-Le même que le réglage précédent.
-
-### PrettySpaceNoEscapes {#prettyspacenoescapes}
-
-Le même que le réglage précédent.
-
-## PrettySpace {#prettyspace}
-
-Diffère de [PrettyCompact](#prettycompact) dans cet espace (caractères d'espace) est utilisé à la place de la grille.
-
-## RowBinary {#rowbinary}
-
-Formats et analyse les données par ligne au format binaire. Les lignes et les valeurs sont répertoriées consécutivement, sans séparateurs.
-Ce format est moins efficace que le format natif car il est basé sur des lignes.
-
-Les entiers utilisent une représentation little-endian de longueur fixe. Par exemple, UInt64 utilise 8 octets.
-DateTime est représenté par UInt32 contenant L'horodatage Unix comme valeur.
-Date est représenté comme un objet UInt16 qui contient le nombre de jours depuis 1970-01-01 comme valeur.
-La chaîne est représentée par une longueur varint (non signée [LEB128](https://en.wikipedia.org/wiki/LEB128)), suivie par les octets de la chaîne.
-FixedString est représenté simplement comme une séquence d'octets.
-
-Le tableau est représenté sous la forme d'une longueur varint (non signée [LEB128](https://en.wikipedia.org/wiki/LEB128)), suivie par les éléments de la matrice.
-
-Pour [NULL](../sql-reference/syntax.md#null-literal) un soutien, un octet supplémentaire contenant 1 ou 0 est ajouté avant chaque [Nullable](../sql-reference/data-types/nullable.md) valeur. Si la valeur est 1, alors la valeur est `NULL` et cet octet est interprétée comme une valeur distincte. Si 0, la valeur après l'octet n'est pas `NULL`.
-
-## Rowbinarywithnamesettypes {#rowbinarywithnamesandtypes}
-
-Semblable à [RowBinary](#rowbinary) mais avec l'ajout de l'en-tête:
-
--   [LEB128](https://en.wikipedia.org/wiki/LEB128)- nombre codé de colonnes (N)
--   N `String`s spécification des noms de colonnes
--   N `String`s spécification des types de colonnes
-
-## Valeur {#data-format-values}
-
-Imprime chaque ligne entre parenthèses. Les lignes sont séparées par des virgules. Il n'y a pas de virgule après la dernière ligne. Les valeurs entre parenthèses sont également séparées par des virgules. Les nombres sont produits dans un format décimal sans guillemets. Les tableaux sont affichés entre crochets. Les chaînes, les dates et les dates avec des heures sont affichées entre guillemets. Les règles d'échappement et l'analyse sont similaires à [TabSeparated](#tabseparated) format. Pendant le formatage, les espaces supplémentaires ne sont pas insérés, mais pendant l'analyse, ils sont autorisés et ignorés (sauf pour les espaces à l'intérieur des valeurs de tableau, qui ne sont pas autorisés). [NULL](../sql-reference/syntax.md) est représentée comme `NULL`.
-
-The minimum set of characters that you need to escape when passing data in Values ​​format: single quotes and backslashes.
-
-C'est le format qui est utilisé dans `INSERT INTO t VALUES ...`, mais vous pouvez également l'utiliser pour le formatage des résultats de requête.
-
-Voir aussi: [input_format_values_interpret_expressions](../operations/settings/settings.md#settings-input_format_values_interpret_expressions) et [input_format_values_deduce_templates_of_expressions](../operations/settings/settings.md#settings-input_format_values_deduce_templates_of_expressions) paramètre.
-
-## Vertical {#vertical}
-
-Imprime chaque valeur sur une ligne distincte avec le nom de colonne spécifié. Ce format est pratique pour imprimer une ou plusieurs lignes si chaque ligne est constituée d'un grand nombre de colonnes.
-
-[NULL](../sql-reference/syntax.md) est sortie `ᴺᵁᴸᴸ`.
-
-Exemple:
-
-``` sql
-SELECT * FROM t_null FORMAT Vertical
-```
-
-``` text
-Row 1:
-──────
-x: 1
-y: ᴺᵁᴸᴸ
-```
-
-Les lignes ne sont pas échappées au format Vertical:
-
-``` sql
-SELECT 'string with \'quotes\' and \t with some special \n characters' AS test FORMAT Vertical
-```
-
-``` text
-Row 1:
-──────
-test: string with 'quotes' and      with some special
- characters
-```
-
-Ce format n'est approprié que pour la sortie d'un résultat de requête, mais pas pour l'analyse (récupération des données à insérer dans une table).
-
-## VerticalRaw {#verticalraw}
-
-Semblable à [Vertical](#vertical), mais avec échapper désactivé. Ce format ne convient que pour la sortie des résultats de requête, pas pour l'analyse (recevoir des données et les insérer dans la table).
-
-## XML {#xml}
-
-Le format XML ne convient que pour la sortie, pas pour l'analyse. Exemple:
-
-``` xml
-<?xml version='1.0' encoding='UTF-8' ?>
-<result>
-        <meta>
-                <columns>

-        <rows>10</rows>
-        <rows_before_limit_at_least>141137</rows_before_limit_at_least>
-</result>
-```
-
-Si le nom de colonne n'a pas un format acceptable, juste ‘field’ est utilisé comme le nom de l'élément. En général, la structure XML suit la structure JSON.
-Just as for JSON, invalid UTF-8 sequences are changed to the replacement character � so the output text will consist of valid UTF-8 sequences.
-
-Dans les valeurs de chaîne, les caractères `<` et `&` sont échappés comme `<` et `&`.
-
-Les tableaux sont produits comme `<array><elem>Hello</elem><elem>World</elem>...</array>`,et n-uplets d' `<tuple><elem>Hello</elem><elem>World</elem>...</tuple>`.
-
-## CapnProto {#capnproto}
-
-Cap'n Proto est un format de message binaire similaire aux tampons de protocole et Thrift, mais pas comme JSON ou MessagePack.
-
-Les messages Cap'n Proto sont strictement typés et ne sont pas auto-descriptifs, ce qui signifie qu'ils ont besoin d'une description de schéma externe. Le schéma est appliqué à la volée et mise en cache pour chaque requête.
-
-``` bash
-$ cat capnproto_messages.bin | clickhouse-client --query "INSERT INTO test.hits FORMAT CapnProto SETTINGS format_schema='schema:Message'"
-```
-
-Où `schema.capnp` ressemble à ceci:
-
-``` capnp
-struct Message {
-  SearchPhrase @0 :Text;
-  c @1 :Uint64;
-}
-```
-
-La désérialisation est efficace et n'augmente généralement pas la charge du système.
-
-Voir aussi [Schéma De Format](#formatschema).
-
-## Protobuf {#protobuf}
-
-Protobuf-est un [Protocol Buffers](https://developers.google.com/protocol-buffers/) format.
-
-Ce format nécessite un schéma de format externe. Le schéma est mis en cache entre les requêtes.
-Clickhouse prend en charge les deux `proto2` et `proto3` syntaxe. Les champs répétés/optionnels/obligatoires sont pris en charge.
-
-Exemples d'utilisation:
-
-``` sql
-SELECT * FROM test.table FORMAT Protobuf SETTINGS format_schema = 'schemafile:MessageType'
-```
-
-``` bash
-cat protobuf_messages.bin | clickhouse-client --query "INSERT INTO test.table FORMAT Protobuf SETTINGS format_schema='schemafile:MessageType'"
-```
-
-où le fichier `schemafile.proto` ressemble à ceci:
-
-``` capnp
-syntax = "proto3";
-
-message MessageType {
-  string name = 1;
-  string surname = 2;
-  uint32 birthDate = 3;
-  repeated string phoneNumbers = 4;
-};
-```
-
-Pour trouver la correspondance entre les colonnes de table et les champs du type de message des tampons de protocole, ClickHouse compare leurs noms.
-Cette comparaison est insensible à la casse et les caractères `_` (trait de soulignement) et `.` (dot) sont considérés comme égaux.
-Si les types d'une colonne et d'un champ de message des tampons de protocole sont différents, la conversion nécessaire est appliquée.
-
-Les messages imbriqués sont pris en charge. Par exemple, pour le champ `z` dans le type de message suivant
-
-``` capnp
-message MessageType {
-  message XType {
-    message YType {
-      int32 z;
-    };
-    repeated YType y;
-  };
-  XType x;
-};
-```
-
-ClickHouse tente de trouver une colonne nommée `x.y.z` (ou `x_y_z` ou `X.y_Z` et ainsi de suite).
-Les messages imbriqués conviennent à l'entrée ou à la sortie d'un [structures de données imbriquées](../sql-reference/data-types/nested-data-structures/nested.md).
-
-Valeurs par défaut définies dans un schéma protobuf comme ceci
-
-``` capnp
-syntax = "proto2";
-
-message MessageType {
-  optional int32 result_per_page = 3 [default = 10];
-}
-```
-
-ne sont pas appliquées; la [valeurs par défaut de la table](../sql-reference/statements/create.md#create-default-values) sont utilisés à leur place.
-
-Clickhouse entrées et sorties messages protobuf dans le `length-delimited` format.
-Cela signifie avant que chaque message devrait être écrit sa longueur comme un [varint](https://developers.google.com/protocol-buffers/docs/encoding#varints).
-Voir aussi [comment lire / écrire des messages protobuf délimités par la longueur dans les langues populaires](https://cwiki.apache.org/confluence/display/GEODE/Delimiting+Protobuf+Messages).

-Types de données Avro non pris en charge: `record` (non-root), `map`
-
-Types de données logiques Avro non pris en charge: `uuid`, `time-millis`, `time-micros`, `duration`
-
-### Insertion De Données {#inserting-data-1}
-
-Pour insérer des données d'un fichier Avro dans la table ClickHouse:
-
-``` bash
-$ cat file.avro | clickhouse-client --query="INSERT INTO {some_table} FORMAT Avro"
-```
-
-Le schéma racine du fichier Avro d'entrée doit être de `record` type.
-
-Pour trouver la correspondance entre les colonnes de table et les champs du schéma Avro ClickHouse compare leurs noms. Cette comparaison est sensible à la casse.
-Les champs inutilisés sont ignorés.
-
-Les types de données des colonnes de la table ClickHouse peuvent différer des champs correspondants des données Avro insérées. Lors de l'insertion de données, ClickHouse interprète les types de données selon le tableau ci-dessus, puis [jeter](../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) les données au type de colonne correspondant.
-
-### La Sélection De Données {#selecting-data-1}
-
-Pour sélectionner des données de la table ClickHouse dans un fichier Avro:
-
-``` bash
-$ clickhouse-client --query="SELECT * FROM {some_table} FORMAT Avro" > file.avro
-```
-
-Les noms de colonnes doivent:
-
--   commencer avec `[A-Za-z_]`
--   par la suite contenir uniquement `[A-Za-z0-9_]`
-
-Sortie Avro fichier de compression et sync intervalle peut être configuré avec [output_format_avro_codec](../operations/settings/settings.md#settings-output_format_avro_codec) et [output_format_avro_sync_interval](../operations/settings/settings.md#settings-output_format_avro_sync_interval) respectivement.
-
-## AvroConfluent {#data-format-avro-confluent}
-
-Avroconfluent prend en charge le décodage des messages Avro à objet unique couramment utilisés avec [Kafka](https://kafka.apache.org/) et [Confluentes Schéma De Registre](https://docs.confluent.io/current/schema-registry/index.html).
-
-Chaque message Avro intègre un id de schéma qui peut être résolu dans le schéma réel à l'aide du registre de schéma.
-
-Les schémas sont mis en cache une fois résolus.
-
-L'URL du registre de schéma est configurée avec [format_avro_schema_registry_url](../operations/settings/settings.md#settings-format_avro_schema_registry_url)
-
-### Types De Données Correspondant {#data_types-matching-1}
-
-Même que [Avro](#data-format-avro)
-
-### Utilisation {#usage}
-
-Pour vérifier rapidement la résolution du schéma, vous pouvez utiliser [kafkacat](https://github.com/edenhill/kafkacat) avec [clickhouse-local](../operations/utilities/clickhouse-local.md):
-
-``` bash
-$ kafkacat -b kafka-broker  -C -t topic1 -o beginning -f '%s' -c 3 | clickhouse-local   --input-format AvroConfluent --format_avro_schema_registry_url 'http://schema-registry' -S "field1 Int64, field2 String"  -q 'select *  from table'
-1 a
-2 b
-3 c
-```
-
-Utiliser `AvroConfluent` avec [Kafka](../engines/table-engines/integrations/kafka.md):
-
-``` sql
-CREATE TABLE topic1_stream
-(
-    field1 String,
-    field2 String
-)
-ENGINE = Kafka()
-SETTINGS
-kafka_broker_list = 'kafka-broker',
-kafka_topic_list = 'topic1',
-kafka_group_name = 'group1',
-kafka_format = 'AvroConfluent';
-
-SET format_avro_schema_registry_url = 'http://schema-registry';
-
-SELECT * FROM topic1_stream;
-```
-
-!!! note "Avertissement"
-    Paramètre `format_avro_schema_registry_url` doit être configuré dans `users.xml` afin de maintenir sa valeur après un redémarrage.

-
-## Schéma De Format {#formatschema}
-
-Le nom du fichier contenant le schéma de format est défini par le paramètre `format_schema`.
-Il est nécessaire de définir ce paramètre lorsqu'il est utilisé dans l'un des formats `Cap'n Proto` et `Protobuf`.
-Le format de schéma est une combinaison d'un nom de fichier et le nom d'un type de message dans ce fichier, délimité par une virgule,
-e.g. `schemafile.proto:MessageType`.
-Si le fichier possède l'extension standard pour le format (par exemple, `.proto` pour `Protobuf`),
-il peut être omis et dans ce cas, le format de schéma ressemble `schemafile:MessageType`.
-
-Si vous entrez ou sortez des données via le [client](../interfaces/cli.md) dans le [mode interactif](../interfaces/cli.md#cli_usage) le nom de fichier spécifié dans le format de schéma
-peut contenir un chemin absolu, soit un chemin relatif au répertoire courant sur le client.
-Si vous utilisez le client dans le [mode batch](../interfaces/cli.md#cli_usage), le chemin d'accès au schéma doit être relatif pour des raisons de sécurité.
-
-Si vous entrez ou sortez des données via le [Interface HTTP](../interfaces/http.md) le nom de fichier spécifié dans le format de schéma
-doit être situé dans le répertoire spécifié dans [format_schema_path](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-format_schema_path)
-dans la configuration du serveur.
-
-## Sauter Les Erreurs {#skippingerrors}
-
-Certains formats tels que `CSV`, `TabSeparated`, `TSKV`, `JSONEachRow`, `Template`, `CustomSeparated` et `Protobuf` pouvez ignorer brisé ligne si erreur d'analyse s'est produite et poursuivre l'analyse à partir du début de la ligne suivante. Voir [input_format_allow_errors_num](../operations/settings/settings.md#settings-input_format_allow_errors_num) et
-[input_format_allow_errors_ratio](../operations/settings/settings.md#settings-input_format_allow_errors_ratio) paramètre.
-Limitation:
-- En cas d'erreur d'analyse `JSONEachRow` ignore toutes les données jusqu'à la nouvelle ligne (ou EOF), donc les lignes doivent être délimitées par `\n` pour compter les erreurs correctement.
-- `Template` et `CustomSeparated` utilisez delimiter après la dernière colonne et delimiter entre les lignes pour trouver le début de la ligne suivante, donc sauter les erreurs ne fonctionne que si au moins l'une d'entre elles n'est pas vide.

-# Interface HTTP {#http-interface}
-
-L'interface HTTP vous permet D'utiliser ClickHouse sur n'importe quelle plate-forme à partir de n'importe quel langage de programmation. Nous l'utilisons pour travailler à partir de Java et Perl, ainsi que des scripts shell. Dans d'autres départements, L'interface HTTP est utilisée à partir de Perl, Python et Go. L'interface HTTP est plus limitée que l'interface native, mais elle a une meilleure compatibilité.
-
-Par défaut, clickhouse-server écoute HTTP sur le port 8123 (cela peut être modifié dans la configuration).
-
-Si vous faites une requête GET / sans Paramètres, elle renvoie le code de réponse 200 et la chaîne définie dans [http_server_default_response](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-http_server_default_response) valeur par défaut “Ok.” (avec un saut de ligne à la fin)
-
-``` bash
-$ curl 'http://localhost:8123/'
-Ok.
-```
-
-Utilisez la requête GET /ping dans les scripts de vérification de la santé. Ce gestionnaire revient toujours “Ok.” (avec un saut de ligne à la fin). Disponible à partir de la version 18.12.13.
-
-``` bash
-$ curl 'http://localhost:8123/ping'
-Ok.
-```
-
-Envoyer la demande sous forme D'URL ‘query’ paramètre, ou comme un POSTE. Ou envoyer le début de la requête dans l' ‘query’ paramètre, et le reste dans le POST (nous expliquerons plus tard pourquoi cela est nécessaire). La taille de L'URL est limitée à 16 Ko, alors gardez cela à l'esprit lors de l'envoi de requêtes volumineuses.
-
-En cas de succès, vous recevez le code de réponse 200 et le résultat dans le corps de réponse.
-Si une erreur se produit, vous recevez le code de réponse 500 et un texte de description de l'erreur dans le corps de la réponse.
-
-Lorsque vous utilisez la méthode GET, ‘readonly’ est définie. En d'autres termes, pour les requêtes qui modifient les données, vous ne pouvez utiliser que la méthode POST. Vous pouvez envoyer la requête elle-même dans le corps du message ou dans le paramètre URL.
-
-Exemple:
-
-``` bash
-$ curl 'http://localhost:8123/?query=SELECT%201'
-1
-
-$ wget -nv -O- 'http://localhost:8123/?query=SELECT 1'
-1
-
-$ echo -ne 'GET /?query=SELECT%201 HTTP/1.0\r\n\r\n' | nc localhost 8123
-HTTP/1.0 200 OK
-Date: Wed, 27 Nov 2019 10:30:18 GMT
-Connection: Close
-Content-Type: text/tab-separated-values; charset=UTF-8
-X-ClickHouse-Server-Display-Name: clickhouse.ru-central1.internal
-X-ClickHouse-Query-Id: 5abe861c-239c-467f-b955-8a201abb8b7f
-X-ClickHouse-Summary: {"read_rows":"0","read_bytes":"0","written_rows":"0","written_bytes":"0","total_rows_to_read":"0"}
-
-1
-```
-
-Comme vous pouvez le voir, curl est un peu gênant en ce sens que les espaces doivent être échappés URL.
-Bien que wget échappe à tout lui-même, nous ne recommandons pas de l'utiliser car il ne fonctionne pas bien sur HTTP 1.1 lors de l'utilisation de keep-alive et Transfer-Encoding: chunked.
-
-``` bash
-$ echo 'SELECT 1' | curl 'http://localhost:8123/' --data-binary @-
-1
-
-$ echo 'SELECT 1' | curl 'http://localhost:8123/?query=' --data-binary @-
-1
-
-$ echo '1' | curl 'http://localhost:8123/?query=SELECT' --data-binary @-
-1
-```
-
-Si une partie de la requête est envoyée dans le paramètre et une partie dans la publication, un saut de ligne est inséré entre ces deux parties de données.
-Exemple (cela ne fonctionnera pas):
-
-``` bash
-$ echo 'ECT 1' | curl 'http://localhost:8123/?query=SEL' --data-binary @-
-Code: 59, e.displayText() = DB::Exception: Syntax error: failed at position 0: SEL
-ECT 1
-, expected One of: SHOW TABLES, SHOW DATABASES, SELECT, INSERT, CREATE, ATTACH, RENAME, DROP, DETACH, USE, SET, OPTIMIZE., e.what() = DB::Exception
-```
-
-Par défaut, les données sont renvoyées au format TabSeparated (pour plus d'informations, voir “Formats” section).
-Vous utilisez la clause FORMAT de la requête pour demander tout autre format.
-
-``` bash
-$ echo 'SELECT 1 FORMAT Pretty' | curl 'http://localhost:8123/?' --data-binary @-
-┏━━━┓
-┃ 1 ┃
-┡━━━┩
-│ 1 │
-└───┘
-```
-
-La méthode POST de transmission des données est nécessaire pour les requêtes INSERT. Dans ce cas, vous pouvez écrire le début de la requête dans le paramètre URL et utiliser POST pour transmettre les données à insérer. Les données à insérer pourraient être, par exemple, un vidage séparé par tabulation de MySQL. De cette façon, la requête INSERT remplace LOAD DATA LOCAL INFILE de MySQL.
-
-Exemples: création d'une table:
-
-``` bash
-$ echo 'CREATE TABLE t (a UInt8) ENGINE = Memory' | curl 'http://localhost:8123/' --data-binary @-
-```
-
-Utilisation de la requête D'insertion familière pour l'insertion de données:
-
-``` bash
-$ echo 'INSERT INTO t VALUES (1),(2),(3)' | curl 'http://localhost:8123/' --data-binary @-
-```
-
-Les données peuvent être envoyées séparément de la requête:
-
-``` bash
-$ echo '(4),(5),(6)' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20VALUES' --data-binary @-
-```
-
-Vous pouvez spécifier n'importe quel format de données. Le ‘Values’ le format est le même que ce qui est utilisé lors de L'écriture INSERT dans les valeurs t:
-
-``` bash
-$ echo '(7),(8),(9)' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20FORMAT%20Values' --data-binary @-
-```
-
-Pour insérer des données à partir d'un vidage séparé par des tabulations, spécifiez le format correspondant:
-
-``` bash
-$ echo -ne '10\n11\n12\n' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20FORMAT%20TabSeparated' --data-binary @-
-```
-
-La lecture de la table des matières. Les données sont sorties dans un ordre aléatoire en raison d'un traitement de requête parallèle:
-
-``` bash
-$ curl 'http://localhost:8123/?query=SELECT%20a%20FROM%20t'
-7
-8
-9
-10
-11
-12
-1
-2
-3
-4
-5
-6
-```
-
-Suppression de la table.
-
-``` bash
-$ echo 'DROP TABLE t' | curl 'http://localhost:8123/' --data-binary @-
-```
-
-Pour les requêtes réussies qui ne renvoient pas de table de données, un corps de réponse vide est renvoyé.
-
-Vous pouvez utiliser le format de compression ClickHouse interne lors de la transmission de données. Les données compressées ont un format non standard, et vous devrez utiliser le spécial `clickhouse-compressor` programme de travail (il s'est installé avec le `clickhouse-client` paquet). Pour augmenter l'efficacité de l'insertion de données, vous pouvez désactiver la vérification de la somme de contrôle côté serveur en utilisant [http_native_compression_disable_checksumming_on_decompress](../operations/settings/settings.md#settings-http_native_compression_disable_checksumming_on_decompress) paramètre.
-
-Si vous avez spécifié `compress=1` dans l'URL, le serveur compresse les données qu'il vous envoie.
-Si vous avez spécifié `decompress=1` dans L'URL, le serveur décompresse les mêmes données que vous transmettez `POST` méthode.
-
-Vous pouvez également choisir d'utiliser [La compression HTTP](https://en.wikipedia.org/wiki/HTTP_compression). Pour envoyer un compressé `POST` demande, ajouter l'en-tête de requête `Content-Encoding: compression_method`. Pour que ClickHouse compresse la réponse, vous devez ajouter `Accept-Encoding: compression_method`. Supports ClickHouse `gzip`, `br`, et `deflate` [méthodes de compression](https://en.wikipedia.org/wiki/HTTP_compression#Content-Encoding_tokens). Pour activer la compression HTTP, vous devez utiliser le ClickHouse [enable_http_compression](../operations/settings/settings.md#settings-enable_http_compression) paramètre. Vous pouvez configurer le niveau de compression des données dans le [http_zlib_compression_level](#settings-http_zlib_compression_level) pour toutes les méthodes de compression.
-
-Vous pouvez l'utiliser pour réduire le trafic réseau lors de la transmission d'une grande quantité de données, ou pour créer des vidages qui sont immédiatement compressés.
-
-Exemples d'envoi de données avec compression:
-
-``` bash
-#Sending data to the server:
-$ curl -vsS "http://localhost:8123/?enable_http_compression=1" -d 'SELECT number FROM system.numbers LIMIT 10' -H 'Accept-Encoding: gzip'
-
-#Sending data to the client:
-$ echo "SELECT 1" | gzip -c | curl -sS --data-binary @- -H 'Content-Encoding: gzip' 'http://localhost:8123/'
-```
-
-!!! note "Note"
-    Certains clients HTTP peuvent décompresser les données du serveur par défaut (avec `gzip` et `deflate`) et vous pouvez obtenir des données décompressées même si vous utilisez les paramètres de compression correctement.
-
-Vous pouvez utiliser l' ‘database’ Paramètre URL pour spécifier la base de données par défaut.
-
-``` bash
-$ echo 'SELECT number FROM numbers LIMIT 10' | curl 'http://localhost:8123/?database=system' --data-binary @-
-0
-1
-2
-3
-4
-5
-6
-7
-8
-9
-```
-
-Par défaut, la base de données enregistrée dans les paramètres du serveur est utilisée comme base de données par défaut. Par défaut, c'est la base de données appelée ‘default’. Alternativement, vous pouvez toujours spécifier la base de données en utilisant un point avant le nom de la table.
-
-Le nom d'utilisateur et le mot de passe peuvent être indiqués de l'une des trois façons suivantes:
-
-1.  Utilisation de L'authentification de base HTTP. Exemple:
-
-<!-- -->
-
-``` bash
-$ echo 'SELECT 1' | curl 'http://user:password@localhost:8123/' -d @-
-```
-
-1.  Dans le ‘user’ et ‘password’ Les paramètres d'URL. Exemple:
-
-<!-- -->
-
-``` bash
-$ echo 'SELECT 1' | curl 'http://localhost:8123/?user=user&password=password' -d @-
-```
-
-1.  Utiliser ‘X-ClickHouse-User’ et ‘X-ClickHouse-Key’ tête. Exemple:
-
-<!-- -->
-
-``` bash
-$ echo 'SELECT 1' | curl -H 'X-ClickHouse-User: user' -H 'X-ClickHouse-Key: password' 'http://localhost:8123/' -d @-
-```
-
-Si le nom d'utilisateur n'est spécifié, le `default` le nom est utilisé. Si le mot de passe n'est spécifié, le mot de passe vide est utilisé.
-Vous pouvez également utiliser les paramètres D'URL pour spécifier des paramètres pour le traitement d'une seule requête ou de profils entiers de paramètres. Exemple: http: / / localhost: 8123/?profil = web & max_rows_to_read=1000000000 & query=sélectionner + 1
-
-Pour plus d'informations, voir le [Paramètre](../operations/settings/index.md) section.
-
-``` bash
-$ echo 'SELECT number FROM system.numbers LIMIT 10' | curl 'http://localhost:8123/?' --data-binary @-
-0
-1
-2
-3
-4
-5
-6
-7
-8
-9
-```
-
-Pour plus d'informations sur les autres paramètres, consultez la section “SET”.
-
-De même, vous pouvez utiliser des sessions ClickHouse dans le protocole HTTP. Pour ce faire, vous devez ajouter l' `session_id` GET paramètre à la demande. Vous pouvez utiliser n'importe quelle chaîne comme ID de session. Par défaut, la session est terminée après 60 secondes d'inactivité. Pour modifier ce délai d'attente, de modifier la `default_session_timeout` dans la configuration du serveur, ou ajoutez le `session_timeout` GET paramètre à la demande. Pour vérifier l'état de la session, utilisez `session_check=1` paramètre. Une seule requête à la fois peut être exécutée dans une seule session.
-
-Vous pouvez recevoir des informations sur le déroulement d'une requête en `X-ClickHouse-Progress` en-têtes de réponse. Pour ce faire, activez [send_progress_in_http_headers](../operations/settings/settings.md#settings-send_progress_in_http_headers). Exemple de l'en-tête de séquence:
-
-``` text
-X-ClickHouse-Progress: {"read_rows":"2752512","read_bytes":"240570816","total_rows_to_read":"8880128"}
-X-ClickHouse-Progress: {"read_rows":"5439488","read_bytes":"482285394","total_rows_to_read":"8880128"}
-X-ClickHouse-Progress: {"read_rows":"8783786","read_bytes":"819092887","total_rows_to_read":"8880128"}
-```
-
-Possibles champs d'en-tête:
-
--   `read_rows` — Number of rows read.
--   `read_bytes` — Volume of data read in bytes.
--   `total_rows_to_read` — Total number of rows to be read.
--   `written_rows` — Number of rows written.
--   `written_bytes` — Volume of data written in bytes.
-
-Les requêtes en cours d'exécution ne s'arrêtent pas automatiquement si la connexion HTTP est perdue. L'analyse et le formatage des données sont effectués côté serveur et l'utilisation du réseau peut s'avérer inefficace.
-Facultatif ‘query_id’ le paramètre peut être passé comme ID de requête (n'importe quelle chaîne). Pour plus d'informations, consultez la section “Settings, replace_running_query”.
-
-Facultatif ‘quota_key’ le paramètre peut être passé comme clé de quota (n'importe quelle chaîne). Pour plus d'informations, consultez la section “Quotas”.
-
-L'interface HTTP permet de transmettre des données externes (tables temporaires externes) pour l'interrogation. Pour plus d'informations, consultez la section “External data for query processing”.
-
-## Tampon De Réponse {#response-buffering}
-
-Vous pouvez activer la mise en mémoire tampon des réponses côté serveur. Le `buffer_size` et `wait_end_of_query` Les paramètres D'URL sont fournis à cette fin.
-
-`buffer_size` détermine le nombre d'octets dans le résultat de tampon dans la mémoire du serveur. Si un corps de résultat est supérieur à ce seuil, le tampon est écrit sur le canal HTTP et les données restantes sont envoyées directement au canal HTTP.
-
-Pour vous assurer que la réponse entière est mise en mémoire tampon, définissez `wait_end_of_query=1`. Dans ce cas, les données ne sont pas stockées dans la mémoire tampon temporaire du serveur de fichiers.
-
-Exemple:
-
-``` bash
-$ curl -sS 'http://localhost:8123/?max_result_bytes=4000000&buffer_size=3000000&wait_end_of_query=1' -d 'SELECT toUInt8(number) FROM system.numbers LIMIT 9000000 FORMAT RowBinary'
-```
-
-Utilisez la mise en mémoire tampon pour éviter les situations où une erreur de traitement de requête s'est produite après l'envoi du code de réponse et des en-têtes HTTP au client. Dans cette situation, un message d'erreur est écrit à la fin du corps de la réponse, et du côté client, l'erreur ne peut être détectée qu'à l'étape d'analyse.
-
-### Requêtes avec paramètres {#cli-queries-with-parameters}
-
-Vous pouvez créer une requête avec paramètres et transmettre des valeurs des paramètres de la requête HTTP. Pour plus d'informations, voir [Requêtes avec des paramètres pour CLI](cli.md#cli-queries-with-parameters).
-
-### Exemple {#example}
-
-``` bash
-$ curl -sS "<address>?param_id=2&param_phrase=test" -d "SELECT * FROM table WHERE int_column = {id:UInt8} and string_column = {phrase:String}"
-```
-
-## Interface HTTP prédéfinie {#predefined_http_interface}
-
-ClickHouse prend en charge des requêtes spécifiques via L'interface HTTP. Par exemple, vous pouvez écrire des données dans un tableau comme suit:
-
-``` bash
-$ echo '(4),(5),(6)' | curl 'http://localhost:8123/?query=INSERT%20INTO%20t%20VALUES' --data-binary @-
-```
-
-ClickHouse prend également en charge L'Interface HTTP prédéfinie qui peut vous aider à une intégration plus facile avec des outils tiers tels que [Prometheus exportateur](https://github.com/percona-lab/clickhouse_exporter).
-
-Exemple:
-
--   Tout d'abord, ajoutez cette section au fichier de configuration du serveur:
-
-<!-- -->
-
-``` xml
-<http_handlers>
-    <rule>
-        <url>/predefined_query</url>
-        <methods>POST,GET</methods>
-        <handler>
-            <type>predefined_query_handler</type>
-            <query>SELECT * FROM system.metrics LIMIT 5 FORMAT Template SETTINGS format_template_resultset = 'prometheus_template_output_format_resultset', format_template_row = 'prometheus_template_output_format_row', format_template_rows_between_delimiter = '\n'</query>
-        </handler>
-    </rule>
-    <rule>...</rule>
-    <rule>...</rule>
-</http_handlers>
-```
-
--   Vous pouvez maintenant demander l'url directement pour les données au format Prometheus:
-
-<!-- -->
-
-``` bash
-$ curl -v 'http://localhost:8123/predefined_query'
-*   Trying ::1...
-* Connected to localhost (::1) port 8123 (#0)
-> GET /predefined_query HTTP/1.1
-> Host: localhost:8123

-
-Comme vous pouvez le voir dans l'exemple, si `<http_handlers>` est configuré dans la configuration.fichier xml et `<http_handlers>` peut contenir beaucoup `<rule>s`. ClickHouse fera correspondre les requêtes HTTP reçues au type prédéfini `<rule>` et la première appariés exécute le gestionnaire. Ensuite, ClickHouse exécutera la requête prédéfinie correspondante si la correspondance est réussie.
-
-> Maintenant `<rule>` pouvez configurer `<method>`, `<headers>`, `<url>`,`<handler>`:
-> `<method>` est responsable de la correspondance de la partie méthode de la requête HTTP. `<method>` entièrement conforme à la définition de [méthode](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods) dans le protocole HTTP. C'est une option de configuration. S'il n'est pas défini dans le fichier de configuration, il ne correspond pas à la partie méthode de la requête HTTP.
->
-> `<url>` est responsable de la correspondance de la partie url de la requête HTTP. Il est compatible avec [RE2](https://github.com/google/re2)s 'expressions régulières. C'est une option de configuration. S'il n'est pas défini dans le fichier de configuration, il ne correspond pas à la partie url de la requête HTTP.
->
-> `<headers>` est responsable de la correspondance de la partie d'en-tête de la requête HTTP. Il est compatible avec les expressions régulières de RE2. C'est une option de configuration. S'il n'est pas défini dans le fichier de configuration, il ne correspond pas à la partie d'en-tête de la requête HTTP.
->
-> `<handler>` contient la partie de traitement principale. Maintenant `<handler>` pouvez configurer `<type>`, `<status>`, `<content_type>`, `<response_content>`, `<query>`, `<query_param_name>`.
-> \> `<type>` prend actuellement en charge trois types: **predefined_query_handler**, **dynamic_query_handler**, **statique**.
-> \>
-> \> `<query>` - utiliser avec le type predefined_query_handler, exécute la requête lorsque le gestionnaire est appelé.
-> \>
-> \> `<query_param_name>` - utiliser avec le type dynamic_query_handler, extrait et exécute la valeur correspondant au `<query_param_name>` valeur dans les paramètres de requête HTTP.
-> \>
-> \> `<status>` - utiliser avec le type statique, code d'état de réponse.
-> \>
-> \> `<content_type>` - utiliser avec statique type, réponse [content-type](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Type).
-> \>
-> \> `<response_content>` - utiliser avec le type statique, le contenu de la réponse envoyé au client, lors de l'utilisation du préfixe ‘file://’ ou ‘config://’, trouver le contenu du fichier ou de la configuration envoyer au client.
-
-Viennent ensuite les méthodes de configuration pour les différents `<type>`.
-
-## predefined_query_handler {#predefined_query_handler}
-
-`<predefined_query_handler>` prend en charge les paramètres de réglage et les valeurs query_params. Vous pouvez configurer `<query>` dans le type de `<predefined_query_handler>`.
-
-`<query>` la valeur est une requête prédéfinie de `<predefined_query_handler>`, qui est exécuté par ClickHouse lorsqu'une requête HTTP est mise en correspondance et que le résultat de la requête est renvoyé. C'est une configuration incontournable.
-
-L'exemple suivant définit les valeurs de `max_threads` et `max_alter_threads` Paramètres, puis interroge la table système pour vérifier si ces paramètres ont été définis avec succès.
-
-Exemple:
-
-``` xml
-<http_handlers>
-    <rule>
-        <url><![CDATA[/query_param_with_url/\w+/(?P<name_1>[^/]+)(/(?P<name_2>[^/]+))?]]></url>
-        <method>GET</method>
-        <headers>
-            <XXX>TEST_HEADER_VALUE</XXX>
-            <PARAMS_XXX><![CDATA[(?P<name_1>[^/]+)(/(?P<name_2>[^/]+))?]]></PARAMS_XXX>
-        </headers>
-        <handler>
-            <type>predefined_query_handler</type>
-            <query>SELECT value FROM system.settings WHERE name = {name_1:String}</query>
-            <query>SELECT name, value FROM system.settings WHERE name = {name_2:String}</query>
-        </handler>
-    </rule>
-</http_handlers>
-```
-
-``` bash
-$ curl -H 'XXX:TEST_HEADER_VALUE' -H 'PARAMS_XXX:max_threads' 'http://localhost:8123/query_param_with_url/1/max_threads/max_alter_threads?max_threads=1&max_alter_threads=2'
-1
-max_alter_threads   2
-```
-
-!!! note "précaution"
-    Dans un `<predefined_query_handler>` prend en charge un seul `<query>` d'un type d'insertion.
-
-## dynamic_query_handler {#dynamic_query_handler}
-
-Dans `<dynamic_query_handler>`, la requête est écrite sous la forme de param de la requête HTTP. La différence est que dans `<predefined_query_handler>`, la requête est écrite dans le fichier de configuration. Vous pouvez configurer `<query_param_name>` dans `<dynamic_query_handler>`.
-
-Clickhouse extrait et exécute la valeur correspondant au `<query_param_name>` valeur dans l'url de la requête HTTP. La valeur par défaut de `<query_param_name>` être `/query` . C'est une option de configuration. Si il n'y a pas de définition dans le fichier de configuration, le paramètre n'est pas passé.
-
-Pour expérimenter cette fonctionnalité, l'exemple définit les valeurs de max_threads et max_alter_threads et demande si les paramètres ont été définis avec succès.
-
-Exemple:
-
-``` xml
-<http_handlers>
-    <rule>
-    <headers>
-        <XXX>TEST_HEADER_VALUE_DYNAMIC</XXX>    </headers>
-    <handler>
-        <type>dynamic_query_handler</type>
-        <query_param_name>query_param</query_param_name>
-    </handler>
-    </rule>
-</http_handlers>
-```
-
-``` bash
-$ curl  -H 'XXX:TEST_HEADER_VALUE_DYNAMIC'  'http://localhost:8123/own?max_threads=1&max_alter_threads=2&param_name_1=max_threads&param_name_2=max_alter_threads&query_param=SELECT%20name,value%20FROM%20system.settings%20where%20name%20=%20%7Bname_1:String%7D%20OR%20name%20=%20%7Bname_2:String%7D'
-max_threads 1
-max_alter_threads   2
-```

-# Interface {#interfaces}
-
-ClickHouse fournit deux interfaces réseau (les deux peuvent être encapsulées en option dans TLS pour plus de sécurité):
-
--   [HTTP](http.md) qui est documenté et facile à utiliser directement.
--   [Natif de TCP](tcp.md) qui a moins de frais généraux.
-
-Dans la plupart des cas, il est recommandé d'utiliser un outil ou une bibliothèque approprié au lieu d'interagir directement avec ceux-ci. Officiellement pris en charge par Yandex sont les suivants:
-
--   [Client de ligne de commande](cli.md)
--   [JDBC](jdbc.md)
--   [Pilote ODBC](odbc.md)
--   [Bibliothèque client c++ ](cpp.md)
-
-Il existe également un large éventail de bibliothèques tierces pour travailler avec ClickHouse:
-
--   [Bibliothèques clientes](third-party/client-libraries.md)
--   [Intégration](third-party/integrations.md)
--   [Les interfaces visuelles](third-party/gui.md)

----
-
-# Interface MySQL {#mysql-interface}
-
-ClickHouse prend en charge le protocole de fil MySQL. Il peut être activé par [mysql_port](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-mysql_port) paramètre dans le fichier de configuration:
-
-``` xml
-<mysql_port>9004</mysql_port>
-```
-
-Exemple de connexion à l'aide d'outil de ligne de commande `mysql`:
-
-``` bash
-$ mysql --protocol tcp -u default -P 9004
-```
-
-Sortie si une connexion a réussi:
-
-``` text
-Welcome to the MySQL monitor.  Commands end with ; or \g.
-Your MySQL connection id is 4
-Server version: 20.2.1.1-ClickHouse
-
-Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.
-
-Oracle is a registered trademark of Oracle Corporation and/or its
-affiliates. Other names may be trademarks of their respective
-owners.
-
-Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
-
-mysql>
-```
-
-Pour la compatibilité avec tous les clients MySQL, il est recommandé de spécifier le mot de passe utilisateur avec [double SHA1](../operations/settings/settings-users.md#password_double_sha1_hex) dans le fichier de configuration.
-Si le mot de passe de l'utilisateur est spécifié [SHA256](../operations/settings/settings-users.md#password_sha256_hex), certains clients ne pourront pas s'authentifier (mysqljs et anciennes versions de l'outil de ligne de commande mysql).
-
-Restriction:
-
--   les requêtes préparées ne sont pas prises en charge
-
--   certains types de données sont envoyés sous forme de chaînes

-# Interface Native (TCP) {#native-interface-tcp}
-
-Le protocole natif est utilisé dans le [client de ligne de commande](cli.md), pour la communication inter-serveur pendant le traitement de requête distribué, et également dans d'autres programmes C++. Malheureusement, le protocole clickhouse natif n'a pas encore de spécification formelle, mais il peut être rétro-conçu à partir du code source ClickHouse (démarrage [ici](https://github.com/ClickHouse/ClickHouse/tree/master/src/Client)) et/ou en interceptant et en analysant le trafic TCP.

-# Caractéristiques distinctives de ClickHouse {#distinctive-features-of-clickhouse}
-
-## Vrai SGBD orienté colonne {#true-column-oriented-dbms}
-
-Dans un vrai SGBD orienté colonne, aucune donnée supplémentaire n'est stockée avec les valeurs. Entre autres choses, cela signifie que les valeurs de longueur constante doivent être prises en charge, pour éviter de stocker leur longueur “number” à côté de ces valeurs. Par exemple, un milliard de valeurs de type UInt8 devrait consommer environ 1 Go non compressé, ou cela affecte fortement l'utilisation du processeur. Il est essentiel de stocker des données de manière compacte (sans “garbage”) même lorsqu'il n'est pas compressé, puisque la vitesse de décompression (utilisation du processeur) dépend principalement du volume de données non compressées.
-
-Il est à noter car il existe des systèmes qui peuvent stocker des valeurs de différentes colonnes séparément, mais qui ne peuvent pas traiter efficacement les requêtes analytiques en raison de leur optimisation pour d'autres scénarios. Les exemples sont HBase, BigTable, Cassandra et HyperTable. Dans ces systèmes, vous obtiendriez un débit d'environ cent mille lignes par seconde, mais pas des centaines de millions de lignes par seconde.
-
-Il est également intéressant de noter que ClickHouse est un système de gestion de base de données, pas une seule base de données. ClickHouse permet de créer des tables et des bases de données en cours d'exécution, de charger des données et d'exécuter des requêtes sans reconfigurer et redémarrer le serveur.
-
-## Compression De Données {#data-compression}
-
-Certains SGBD orientés colonne (InfiniDB CE et MonetDB) n'utilisent pas la compression de données. Cependant, la compression des données joue un rôle clé dans la réalisation d'excellentes performances.
-
-## Stockage de données sur disque {#disk-storage-of-data}
-
-Garder les données physiquement triées par clé primaire permet d'extraire des données pour ses valeurs spécifiques ou plages de valeurs avec une faible latence, moins de quelques dizaines de millisecondes. Certains SGBD orientés colonne (tels que SAP HANA et Google PowerDrill) ne peuvent fonctionner qu'en RAM. Cette approche encourage l'allocation d'un budget matériel plus important que ce qui est nécessaire pour l'analyse en temps réel. ClickHouse est conçu pour fonctionner sur des disques durs réguliers, ce qui signifie que le coût par Go de stockage de données est faible, mais SSD et RAM supplémentaire sont également entièrement utilisés si disponible.
-
-## Traitement parallèle sur plusieurs cœurs {#parallel-processing-on-multiple-cores}
-
-Les grandes requêtes sont parallélisées naturellement, en prenant toutes les ressources nécessaires disponibles sur le serveur actuel.
-
-## Traitement distribué sur plusieurs serveurs {#distributed-processing-on-multiple-servers}
-
-Presque aucun des SGBD en colonnes mentionnés ci-dessus ne prend en charge le traitement des requêtes distribuées.
-Dans ClickHouse, les données peuvent résider sur différents fragments. Chaque fragment peut être un groupe de répliques utilisées pour la tolérance aux pannes. Tous les fragments sont utilisés pour exécuter une requête en parallèle, de façon transparente pour l'utilisateur.
-
-## Prise en charge SQL {#sql-support}
-
-ClickHouse prend en charge un langage de requête déclarative basé sur SQL qui est identique à la norme SQL dans de nombreux cas.
-Les requêtes prises en charge incluent les clauses GROUP BY, ORDER BY, les sous-requêtes in FROM, IN et JOIN, ainsi que les sous-requêtes scalaires.
-Les sous-requêtes dépendantes et les fonctions de fenêtre ne sont pas prises en charge.
-
-## Moteur Vectoriel {#vector-engine}
-
-Les données ne sont pas seulement stockées par des colonnes, mais sont traitées par des vecteurs (parties de colonnes), ce qui permet d'atteindre une efficacité élevée du processeur.
-
-## Données en temps réel des Mises à jour {#real-time-data-updates}
-
-ClickHouse prend en charge les tables avec une clé primaire. Pour effectuer rapidement des requêtes sur la plage de la clé primaire, les données sont triées progressivement à l'aide de l'arborescence de fusion. Pour cette raison, les données peuvent être continuellement ajoutées à la table. Pas de verrouillage lorsque de nouvelles données sont ingérés.
-
-## Index {#index}
-
-Avoir une donnée physiquement triée par clé primaire permet d'extraire des données pour ses valeurs spécifiques ou plages de valeurs avec une faible latence, moins de quelques dizaines de millisecondes.
-
-## Convient pour les requêtes en ligne {#suitable-for-online-queries}
-
-Faible latence signifie que les requêtes peuvent être traitées sans délai et sans essayer de préparer une réponse à l'avance, au même moment pendant le chargement de la page de l'interface utilisateur. En d'autres termes, en ligne.
-
-## Prise en charge des calculs approximatifs {#support-for-approximated-calculations}
-
-ClickHouse offre différentes façons d'échanger la précision pour la performance:
-
-1.  Fonctions d'agrégation pour le calcul approximatif du nombre de valeurs distinctes, de médianes et de quantiles.
-2.  L'exécution d'une requête basée sur une partie (échantillon) de données et obtenir un pseudo résultat. Dans ce cas, proportionnellement, moins de données sont récupérées à partir du disque.
-3.  L'exécution d'une agrégation pour un nombre limité de clés aléatoires, au lieu de toutes les clés. Sous certaines conditions pour la distribution des clés dans les données, cela fournit un résultat raisonnablement précis tout en utilisant moins de ressources.
-
-## Prise en charge de la réplication et de l'intégrité des données {#data-replication-and-data-integrity-support}
-
-ClickHouse utilise la réplication multi-maître asynchrone. Après avoir été écrit dans n'importe quelle réplique disponible, toutes les répliques restantes récupèrent leur copie en arrière-plan. Le système conserve des données identiques sur différentes répliques. La récupération après la plupart des échecs est effectuée automatiquement ou semi-automatiquement dans les cas complexes.
-
-Pour plus d'informations, consultez la section [Réplication des données](../engines/table-engines/mergetree-family/replication.md).
-
-## Caractéristiques qui peuvent être considérées comme des inconvénients {#clickhouse-features-that-can-be-considered-disadvantages}
-
-1.  Pas de transactions à part entière.
-2.  Manque de capacité à modifier ou supprimer des données déjà insérées avec un taux élevé et une faible latence. Des suppressions et des mises à jour par lots sont disponibles pour nettoyer ou modifier les données, par exemple pour [GDPR](https://gdpr-info.eu).
-3.  L'index clairsemé rend ClickHouse pas si approprié pour les requêtes ponctuelles récupérant des lignes simples par leurs clés.

-# Histoire De ClickHouse {#clickhouse-history}
-
-ClickHouse a été développé initialement au pouvoir [Yandex.Metrica](https://metrica.yandex.com/), [la deuxième plus grande plateforme d'analyse dans le monde](http://w3techs.com/technologies/overview/traffic_analysis/all) et continue à être le composant de base de ce système. Avec plus de 13 Billions d'enregistrements dans la base de données et plus de 20 milliards d'événements par jour, ClickHouse permet de générer des rapports personnalisés à la volée directement à partir de données non agrégées. Cet article couvre brièvement les objectifs de ClickHouse dans les premiers stades de son développement.
-
-Yandex.Metrica construit des rapports personnalisés à la volée en fonction des hits et des sessions, avec des segments arbitraires définis par l'utilisateur. Faisant souvent requiert la construction d'agrégats complexes, tels que le nombre d'utilisateurs uniques. De nouvelles données pour la création d'un rapport arrivent en temps réel.
-
-En avril 2014, Yandex.Metrica suivait environ 12 milliards d'événements (pages vues et clics) par jour. Tous ces événements doivent être stockés à créer des rapports personnalisés. Une seule requête peut exiger de la numérisation de millions de lignes en quelques centaines de millisecondes, ou des centaines de millions de lignes en quelques secondes.
-
-## Utilisation dans Yandex.Metrica et autres Services Yandex {#usage-in-yandex-metrica-and-other-yandex-services}
-
-ClickHouse sert à des fins multiples dans Yandex.Metrica.
-Sa tâche principale est de créer des rapports en mode en ligne en utilisant des données non agrégées. Il utilise un cluster de 374 serveurs qui stockent plus de 20,3 billions de lignes dans la base de données. Le volume de données compressées est d'environ 2 PB, sans tenir compte des doublons et des répliques. Le volume de données non compressées (au format TSV) serait d'environ 17 PB.
-
-ClickHouse joue également un rôle clé dans les processus suivants:
-
--   Stockage des données pour la relecture de Session de Yandex.Metrica.
--   Traitement des données intermédiaires.
--   Création de rapports globaux avec Analytics.
--   Exécution de requêtes pour le débogage du Yandex.Moteur Metrica.
--   Analyse des journaux de L'API et de l'interface utilisateur.
-
-De nos jours, il existe plusieurs dizaines d'installations ClickHouse dans D'autres services et départements Yandex: recherche verticale, E-commerce, Publicité, business analytics, développement mobile, Services personnels et autres.
-
-## Données agrégées et non agrégées {#aggregated-and-non-aggregated-data}
-
-Il y a une opinion répandue que pour calculer efficacement les statistiques, vous devez agréger les données car cela réduit le volume de données.
-
-Mais l'agrégation de données est livré avec beaucoup de limitations:
-
--   Vous devez disposer d'une liste prédéfinie des rapports requis.
--   L'utilisateur ne peut pas créer de rapports personnalisés.
--   Lors de l'agrégation sur un grand nombre de clés distinctes, le volume de données est à peine réduit, l'agrégation est donc inutile.
--   Pour un grand nombre de rapports, il y a trop de variations d'agrégation (explosion combinatoire).
--   Lors de l'agrégation de clés avec une cardinalité élevée (telles que les URL), le volume de données n'est pas réduit de beaucoup (moins de deux fois).
--   Pour cette raison, le volume de données avec l'agrégation peut augmenter au lieu de diminuer.
--   Les utilisateurs ne voient pas tous les rapports que nous générons pour eux. Une grande partie de ces calculs est inutile.
--   L'intégrité logique des données peut être violée pour diverses agrégations.
-
-Si nous n'agrégeons rien et travaillons avec des données non agrégées, cela pourrait réduire le volume des calculs.
-
-Cependant, avec l'agrégation, une partie importante du travail est déconnectée et achevée relativement calmement. En revanche, les calculs en ligne nécessitent un calcul aussi rapide que possible, car l'utilisateur attend le résultat.
-
-Yandex.Metrica dispose d'un système spécialisé d'agrégation des données appelé Metrage, qui a été utilisé pour la majorité des rapports.
-À partir de 2009, Yandex.Metrica a également utilisé une base de données OLAP spécialisée pour les données non agrégées appelée OLAPServer, qui était auparavant utilisée pour le générateur de rapports.
-OLAPServer a bien fonctionné pour les données non agrégées, mais il avait de nombreuses restrictions qui ne lui permettaient pas d'être utilisé pour tous les rapports comme souhaité. Ceux-ci comprenaient le manque de prise en charge des types de données (uniquement des nombres) et l'incapacité de mettre à jour progressivement les données en temps réel (cela ne pouvait être fait qu'en réécrivant les données quotidiennement). OLAPServer n'est pas un SGBD, mais une base de données spécialisée.
-
-L'objectif initial de ClickHouse était de supprimer les limites D'OLAPServer et de résoudre le problème du travail avec des données non agrégées pour tous les rapports, mais au fil des ans, il est devenu un système de gestion de base de données polyvalent adapté à un large éventail de tâches analytiques.

-# Performance {#performance}
-
-Selon les résultats des tests internes chez Yandex, ClickHouse affiche les meilleures performances (à la fois le débit le plus élevé pour les requêtes longues et la latence la plus faible pour les requêtes courtes) pour des scénarios d'exploitation comparables parmi les systèmes de sa classe disponibles pour les tests. Vous pouvez afficher les résultats du test sur un [page séparée](https://clickhouse.tech/benchmark/dbms/).
-
-De nombreux points de repère indépendants sont arrivés à des conclusions similaires. Ils ne sont pas difficiles à trouver en utilisant une recherche sur internet, ou vous pouvez voir [notre petite collection de liens](https://clickhouse.tech/#independent-benchmarks).
-
-## Débit pour une seule grande requête {#throughput-for-a-single-large-query}
-
-Le débit peut être mesuré en lignes par seconde ou en mégaoctets par seconde. Si les données sont placées dans le cache de page, une requête pas trop complexe est traitée sur du matériel moderne à une vitesse d'environ 2-10 GB / s de données non compressées sur un seul serveur (pour les cas les plus simples, la vitesse peut atteindre 30 GB/s). Si les données ne sont pas placées dans le cache de page, la vitesse dépend du sous-système de disque et du taux de compression des données. Par exemple, si le sous-système de disque permet de lire des données à 400 Mo/s et que le taux de compression des données est de 3, la vitesse devrait être d'environ 1,2 Go/s. Pour obtenir la vitesse en lignes par seconde, divisez la vitesse en octets par seconde par la taille totale des colonnes utilisées dans la requête. Par exemple, si 10 octets de colonnes sont extraites, la vitesse devrait être d'environ 100 à 200 millions de lignes par seconde.
-
-La vitesse de traitement augmente presque linéairement pour le traitement distribué, mais seulement si le nombre de lignes résultant de l'agrégation ou du tri n'est pas trop important.
-
-## Latence Lors Du Traitement Des Requêtes Courtes {#latency-when-processing-short-queries}
-
-Si une requête utilise une clé primaire et ne sélectionne pas trop de colonnes et de lignes à traiter (des centaines de milliers), Vous pouvez vous attendre à moins de 50 millisecondes de latence (un seul chiffre de millisecondes dans le meilleur des cas) si les données sont placées dans le cache de page. Sinon, la latence est principalement dominée par le nombre de recherches. Si vous utilisez des lecteurs de disque rotatifs, pour un système qui n'est pas surchargé, la latence peut être estimée avec cette formule: `seek time (10 ms) * count of columns queried * count of data parts`.
-
-## Débit lors du traitement d'une grande quantité de requêtes courtes {#throughput-when-processing-a-large-quantity-of-short-queries}
-
-Dans les mêmes conditions, ClickHouse peut traiter plusieurs centaines de requêtes par seconde sur un seul serveur (jusqu'à plusieurs milliers dans le meilleur des cas). Étant donné que ce scénario n'est pas typique pour les SGBD analytiques, nous vous recommandons d'attendre un maximum de 100 requêtes par seconde.
-
-## Performances Lors De L'Insertion De Données {#performance-when-inserting-data}
-
-Nous vous recommandons d'insérer des données dans des paquets d'au moins 1000 lignes, ou pas plus qu'une seule demande par seconde. Lors de l'insertion dans une table MergeTree à partir d'un dump séparé par des tabulations, la vitesse d'insertion peut être de 50 à 200 Mo/s. Si les lignes insérées ont une taille d'environ 1 KO, La vitesse sera de 50 000 à 200 000 lignes par seconde. Si les lignes sont petites, les performances peuvent être plus élevées en lignes par seconde (sur les données du système de bannière -`>` 500 000 lignes par seconde; sur les données de Graphite -`>` 1 000 000 lignes par seconde). Pour améliorer les performances, vous pouvez effectuer plusieurs requêtes D'insertion en parallèle, qui s'adaptent linéairement.

----
-
-# Le Contrôle d'accès et de Gestion de Compte {#access-control}
-
-Clickhouse prend en charge la gestion du contrôle d'accès basée sur [RBAC](https://en.wikipedia.org/wiki/Role-based_access_control) approche.
-
-Entités d'accès ClickHouse:
-- [Compte d'utilisateur](#user-account-management)
-- [Rôle](#role-management)
-- [La Ligne Politique](#row-policy-management)
-- [Les Paramètres De Profil](#settings-profiles-management)
-- [Quota](#quotas-management)
-
-Vous pouvez configurer des entités d'accès à l'aide de:
-
--   Flux de travail piloté par SQL.
-
-    Vous avez besoin de [permettre](#enabling-access-control) cette fonctionnalité.
-
--   Serveur [les fichiers de configuration](configuration-files.md) `users.xml` et `config.xml`.
-
-Nous vous recommandons D'utiliser un workflow piloté par SQL. Les deux méthodes de configuration fonctionnent simultanément, donc si vous utilisez les fichiers de configuration du serveur pour gérer les comptes et les droits d'accès, vous pouvez passer doucement au flux de travail piloté par SQL.
-
-!!! note "Avertissement"
-    Vous ne pouvez pas gérer la même entité d'accès par les deux méthodes de configuration simultanément.
-
-## Utilisation {#access-control-usage}
-
-Par défaut, le serveur ClickHouse fournit le compte utilisateur `default` ce qui n'est pas autorisé à utiliser le contrôle D'accès piloté par SQL et la gestion de compte, mais a tous les droits et autorisations. Le `default` compte d'utilisateur est utilisé dans tous les cas, lorsque l'utilisateur n'est pas défini, par exemple, lors de la connexion du client ou dans les requêtes distribuées. Dans le traitement des requêtes distribuées, un compte utilisateur par défaut est utilisé si la configuration du serveur ou du cluster ne spécifie pas [d'utilisateur et mot de passe](../engines/table-engines/special/distributed.md) propriété.
-
-Si vous commencez simplement à utiliser ClickHouse, vous pouvez utiliser le scénario suivant:
-
-1.  [Permettre](#enabling-access-control) Contrôle D'accès piloté par SQL et gestion de compte pour le `default` utilisateur.
-2.  Connexion en vertu de la `default` compte d'utilisateur et de créer tous les utilisateurs. N'oubliez pas de créer un compte d'administrateur (`GRANT ALL ON *.* WITH GRANT OPTION TO admin_user_account`).
-3.  [Restreindre les autorisations](settings/permissions-for-queries.md#permissions_for_queries) pour l' `default` utilisateur et désactiver le contrôle D'accès piloté par SQL et la gestion des comptes pour elle.
-
-### Propriétés de la Solution actuelle {#access-control-properties}
-
--   Vous pouvez accorder des autorisations pour les bases de données et les tables même si elles n'existent pas.
--   Si une table a été supprimée, tous les privilèges correspondant à cette table ne sont pas révoqués. Ainsi, si une nouvelle table est créée plus tard avec le même nom, tous les privilèges redeviennent réels. Pour révoquer les privilèges correspondant à la table supprimée, vous devez effectuer, par exemple, l' `REVOKE ALL PRIVILEGES ON db.table FROM ALL` requête.
--   Il n'y a pas de paramètres de durée de vie pour les privilèges.
-
-## Compte d'utilisateur {#user-account-management}
-
-Un compte d'utilisateur est une entité qui permet d'autoriser quelqu'un à ClickHouse. Un compte utilisateur contient:
-
--   Informations d'Identification.
--   [Privilège](../sql-reference/statements/grant.md#grant-privileges) qui définissent l'étendue des requêtes que l'utilisateur peut effectuer.
--   Hôtes à partir desquels la connexion au serveur ClickHouse est autorisée.
--   Rôles accordés et par défaut.
--   Paramètres avec leurs contraintes qui s'appliquent par défaut lors de la connexion de l'utilisateur.
--   Profils de paramètres assignés.
-
-Des privilèges à un compte d'utilisateur peuvent être accordés par [GRANT](../sql-reference/statements/grant.md) requête ou en attribuant [rôle](#role-management). Pour révoquer les privilèges d'un utilisateur, ClickHouse fournit [REVOKE](../sql-reference/statements/revoke.md) requête. Pour lister les privilèges d'un utilisateur, utilisez - [SHOW GRANTS](../sql-reference/statements/show.md#show-grants-statement) déclaration.
-
-Gestion des requêtes:
-
--   [CREATE USER](../sql-reference/statements/create.md#create-user-statement)
--   [ALTER USER](../sql-reference/statements/alter.md#alter-user-statement)
--   [DROP USER](../sql-reference/statements/misc.md#drop-user-statement)
--   [SHOW CREATE USER](../sql-reference/statements/show.md#show-create-user-statement)
-
-### Paramètres Application {#access-control-settings-applying}
-
-Les paramètres peuvent être définis de différentes manières: pour un compte utilisateur, dans ses profils de rôles et de paramètres accordés. Lors d'une connexion utilisateur, si un paramètre est défini dans différentes entités d'accès, la valeur et les contraintes de ce paramètre sont appliquées par les priorités suivantes (de plus haut à plus bas):
-
-1.  Paramètre de compte utilisateur.
-2.  Les paramètres de rôles par défaut du compte d'utilisateur. Si un paramètre est défini dans certains rôles, l'ordre de la mise en application n'est pas défini.
-3.  Les paramètres dans les profils de paramètres attribués à un utilisateur ou à ses rôles par défaut. Si un paramètre est défini dans certains profils, l'ordre d'application des paramètres n'est pas défini.
-4.  Paramètres appliqués à l'ensemble du serveur par défaut [profil par défaut](server-configuration-parameters/settings.md#default-profile).
-
-## Rôle {#role-management}
-
-Le rôle est un conteneur pour l'accès des entités qui peuvent être accordées à un compte d'utilisateur.
-
-Rôle contient:
-
--   [Privilège](../sql-reference/statements/grant.md#grant-privileges)
--   Paramètres et contraintes
--   Liste des rôles attribués
-
-Gestion des requêtes:
-
--   [CREATE ROLE](../sql-reference/statements/create.md#create-role-statement)
--   [ALTER ROLE](../sql-reference/statements/alter.md#alter-role-statement)
--   [DROP ROLE](../sql-reference/statements/misc.md#drop-role-statement)
--   [SET ROLE](../sql-reference/statements/misc.md#set-role-statement)
--   [SET DEFAULT ROLE](../sql-reference/statements/misc.md#set-default-role-statement)
--   [SHOW CREATE ROLE](../sql-reference/statements/show.md#show-create-role-statement)
-
-Les privilèges d'un rôle peuvent être accordés par [GRANT](../sql-reference/statements/grant.md) requête. Pour révoquer les privilèges D'un rôle ClickHouse fournit [REVOKE](../sql-reference/statements/revoke.md) requête.
-
-## La Ligne Politique {#row-policy-management}
-
-La stratégie de ligne est un filtre qui définit les lignes disponibles pour un utilisateur ou pour un rôle. La stratégie de ligne contient des filtres pour une table spécifique et une liste de rôles et / ou d'utilisateurs qui doivent utiliser cette stratégie de ligne.
-
-Gestion des requêtes:
-
--   [CREATE ROW POLICY](../sql-reference/statements/create.md#create-row-policy-statement)
--   [ALTER ROW POLICY](../sql-reference/statements/alter.md#alter-row-policy-statement)
--   [DROP ROW POLICY](../sql-reference/statements/misc.md#drop-row-policy-statement)
--   [SHOW CREATE ROW POLICY](../sql-reference/statements/show.md#show-create-row-policy-statement)
-
-## Les Paramètres De Profil {#settings-profiles-management}
-
-Paramètres profil est une collection de [paramètre](settings/index.md). Le profil paramètres contient les paramètres et les contraintes, ainsi que la liste des rôles et/ou des utilisateurs auxquels ce quota est appliqué.
-
-Gestion des requêtes:
-
--   [CREATE SETTINGS PROFILE](../sql-reference/statements/create.md#create-settings-profile-statement)
--   [ALTER SETTINGS PROFILE](../sql-reference/statements/alter.md#alter-settings-profile-statement)
--   [DROP SETTINGS PROFILE](../sql-reference/statements/misc.md#drop-settings-profile-statement)
--   [SHOW CREATE SETTINGS PROFILE](../sql-reference/statements/show.md#show-create-settings-profile-statement)
-
-## Quota {#quotas-management}
-
-Le Quota limite l'utilisation des ressources. Voir [Quota](quotas.md).
-
-Quota contient un ensemble de limites pour certaines durées, et la liste des rôles et/ou des utilisateurs qui devrait utiliser ce quota.
-
-Gestion des requêtes:
-
--   [CREATE QUOTA](../sql-reference/statements/create.md#create-quota-statement)
--   [ALTER QUOTA](../sql-reference/statements/alter.md#alter-quota-statement)
--   [DROP QUOTA](../sql-reference/statements/misc.md#drop-quota-statement)
--   [SHOW CREATE QUOTA](../sql-reference/statements/show.md#show-create-quota-statement)
-
-## Activation du contrôle D'accès piloté par SQL et de la gestion de Compte {#enabling-access-control}
-
--   Configurez un répertoire pour le stockage des configurations.
-
-    Clickhouse stocke les configurations d'entité d'accès dans le dossier défini dans [access_control_path](server-configuration-parameters/settings.md#access_control_path) paramètre de configuration du serveur.
-
--   Activez le contrôle D'accès piloté par SQL et la gestion de compte pour au moins un compte d'utilisateur.
-
-    Par défaut, le contrôle D'accès piloté par SQL et la gestion des comptes sont activés pour tous les utilisateurs. Vous devez configurer au moins un utilisateur dans le `users.xml` fichier de configuration et affecter 1 au [access_management](settings/settings-users.md#access_management-user-setting) paramètre.

-# La Sauvegarde Des Données {#data-backup}
-
-Alors [réplication](../engines/table-engines/mergetree-family/replication.md) provides protection from hardware failures, it does not protect against human errors: accidental deletion of data, deletion of the wrong table or a table on the wrong cluster, and software bugs that result in incorrect data processing or data corruption. In many cases mistakes like these will affect all replicas. ClickHouse has built-in safeguards to prevent some types of mistakes — for example, by default [vous ne pouvez pas simplement supprimer des tables avec un moteur de type MergeTree contenant plus de 50 Go de données](server-configuration-parameters/settings.md#max-table-size-to-drop). Toutefois, ces garanties ne couvrent pas tous les cas possibles et peuvent être contournés.
-
-Afin d'atténuer efficacement les erreurs humaines possibles, vous devez préparer soigneusement une stratégie de sauvegarde et de restauration de vos données **préalablement**.
-
-Chaque entreprise a différentes ressources disponibles et les exigences de l'entreprise, donc il n'y a pas de solution universelle pour les sauvegardes et restaurations ClickHouse qui s'adaptera à toutes les situations. Ce qui fonctionne pour un gigaoctet de données ne fonctionnera probablement pas pour des dizaines de pétaoctets. Il existe une variété d'approches possibles avec leurs propres avantages et inconvénients, qui sera discuté ci-dessous. C'est une bonne idée d'utiliser plusieurs approches au lieu d'un seul, afin de compenser leurs lacunes.
-
-!!! note "Note"
-    Gardez à l'esprit que si vous avez sauvegardé quelque chose et que vous n'avez jamais essayé de le restaurer, il est probable que la restauration ne fonctionnera pas correctement lorsque vous en avez réellement besoin (ou du moins cela prendra plus de temps que ce que les entreprises peuvent tolérer). Donc, quelle que soit l'approche de sauvegarde que vous choisissez, assurez-vous d'automatiser le processus de restauration et de le pratiquer sur un cluster clickhouse de rechange régulièrement.
-
-## Dupliquer Les Données Sources Ailleurs {#duplicating-source-data-somewhere-else}
-
-Souvent, les données qui sont ingérées dans ClickHouse sont livrées via une sorte de file d'attente persistante, telle que [Apache Kafka](https://kafka.apache.org). Dans ce cas, il est possible de configurer un ensemble supplémentaire d'abonnés qui liront le même flux de données pendant qu'il est écrit dans ClickHouse et le stockeront dans un stockage à froid quelque part. La plupart des entreprises ont déjà un stockage à froid recommandé par défaut, qui pourrait être un magasin d'objets ou un système de fichiers distribué comme [HDFS](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html).
-
-## Instantanés Du Système De Fichiers {#filesystem-snapshots}
-
-Certains systèmes de fichiers locaux fournissent des fonctionnalités d'instantané (par exemple, [ZFS](https://en.wikipedia.org/wiki/ZFS)), mais ils pourraient ne pas être le meilleur choix pour servir les requêtes actives. Une solution possible consiste à créer des répliques supplémentaires avec ce type de système de fichiers et à les exclure du [Distribué](../engines/table-engines/special/distributed.md) les tables qui sont utilisés pour `SELECT` requête. Les instantanés sur ces répliques seront hors de portée des requêtes qui modifient les données. En prime, ces répliques pourraient avoir des configurations matérielles spéciales avec plus de disques attachés par serveur, ce qui serait rentable.
-
-## clickhouse-copieur {#clickhouse-copier}
-
-[clickhouse-copieur](utilities/clickhouse-copier.md) est un outil polyvalent qui a été initialement créé pour re-shard petaoctet - sized tables. Il peut également être utilisé à des fins de sauvegarde et de restauration car il copie de manière fiable les données entre les tables ClickHouse et les clusters.
-
-Pour de plus petits volumes de données, un simple `INSERT INTO ... SELECT ...` les tables distantes peuvent également fonctionner.
-
-## Manipulations avec des pièces {#manipulations-with-parts}
-
-ClickHouse permet d'utiliser le `ALTER TABLE ... FREEZE PARTITION ...` requête pour créer une copie locale des partitions de table. Ceci est implémenté en utilisant des liens durs vers le `/var/lib/clickhouse/shadow/` dossier, donc il ne consomme généralement pas d'espace disque supplémentaire pour les anciennes données. Les copies créées des fichiers ne sont pas gérées par clickhouse server, vous pouvez donc les laisser là: vous aurez une sauvegarde simple qui ne nécessite aucun système externe supplémentaire, mais elle sera toujours sujette à des problèmes matériels. Pour cette raison, il est préférable de les copier à distance vers un autre emplacement, puis de supprimer les copies locales. Les systèmes de fichiers distribués et les magasins d'objets sont toujours une bonne option pour cela, mais les serveurs de fichiers attachés normaux avec une capacité suffisante peuvent également fonctionner (dans ce cas, le transfert se fera via le système de fichiers réseau ou peut-être [rsync](https://en.wikipedia.org/wiki/Rsync)).
-
-Pour plus d'informations sur les requêtes liées aux manipulations de [Modifier la documentation](../sql-reference/statements/alter.md#alter_manipulations-with-partitions).
-
-Un outil tiers est disponible pour automatiser cette approche: [clickhouse-sauvegarde](https://github.com/AlexAkulov/clickhouse-backup).

-toc_title: Fichiers De Configuration
----
-
-# Fichiers De Configuration {#configuration_files}
-
-ClickHouse prend en charge la gestion de la configuration multi-fichiers. Le fichier de configuration du serveur principal est `/etc/clickhouse-server/config.xml`. Les autres fichiers doivent être dans le `/etc/clickhouse-server/config.d` répertoire.
-
-!!! note "Note"
-    Tous les fichiers de configuration doivent être au format XML. Aussi, ils doivent avoir le même élément racine, généralement `<yandex>`.
-
-Certains paramètres spécifiés dans le fichier de configuration principal peuvent être remplacés dans d'autres fichiers de configuration. Le `replace` ou `remove` les attributs peuvent être spécifiés pour les éléments de ces fichiers de configuration.
-
-Si ni l'un ni l'autre n'est spécifié, il combine le contenu des éléments de manière récursive, remplaçant les valeurs des enfants en double.
-
-Si `replace` est spécifié, il remplace l'élément entier par celui spécifié.
-
-Si `remove` est spécifié, il supprime l'élément.
-
-La configuration peut également définir “substitutions”. Si un élément a le `incl` attribut, la substitution correspondante du fichier sera utilisée comme valeur. Par défaut, le chemin d'accès au fichier avec des substitutions est `/etc/metrika.xml`. Ceci peut être changé dans le [include_from](server-configuration-parameters/settings.md#server_configuration_parameters-include_from) élément dans la configuration du serveur. Les valeurs de substitution sont spécifiées dans `/yandex/substitution_name` les éléments de ce fichier. Si une substitution spécifiée dans `incl` n'existe pas, il est enregistré dans le journal. Pour empêcher ClickHouse de consigner les substitutions manquantes, spécifiez `optional="true"` attribut (par exemple, les paramètres de [macro](server-configuration-parameters/settings.md)).
-
-Les Substitutions peuvent également être effectuées à partir de ZooKeeper. Pour ce faire, spécifiez l'attribut `from_zk = "/path/to/node"`. La valeur de l'élément est remplacé par le contenu du noeud au `/path/to/node` dans ZooKeeper. Vous pouvez également placer un sous-arbre XML entier sur le nœud ZooKeeper et il sera entièrement inséré dans l'élément source.
-
-Le `config.xml` le fichier peut spécifier une configuration distincte avec les paramètres utilisateur, les profils et les quotas. Le chemin relatif à cette configuration est défini dans `users_config` élément. Par défaut, il est `users.xml`. Si `users_config` est omis, les paramètres utilisateur, les profils et les quotas sont `config.xml`.
-
-La configuration des utilisateurs peut être divisée en fichiers séparés similaires à `config.xml` et `config.d/`.
-Nom du répertoire est défini comme `users_config` sans `.xml` postfix concaténé avec `.d`.
-Répertoire `users.d` est utilisé par défaut, comme `users_config` par défaut `users.xml`.
-Par exemple, vous pouvez avoir séparé fichier de configuration pour chaque utilisateur comme ceci:
-
-``` bash
-$ cat /etc/clickhouse-server/users.d/alice.xml
-```
-
-``` xml
-<yandex>
-    <users>
-      <alice>
-          <profile>analytics</profile>
-            <networks>
-                  <ip>::/0</ip>
-            </networks>
-          <password_sha256_hex>...</password_sha256_hex>
-          <quota>analytics</quota>
-      </alice>
-    </users>
-</yandex>
-```
-
-Pour chaque fichier de configuration, le serveur génère également `file-preprocessed.xml` les fichiers lors du démarrage. Ces fichiers contiennent toutes les remplacements et des remplacements, et ils sont destinés à l'usage informatif. Si des substitutions ZooKeeper ont été utilisées dans les fichiers de configuration mais que ZooKeeper n'est pas disponible au démarrage du serveur, le serveur charge la configuration à partir du fichier prétraité.
-
-Le serveur suit les changements dans les fichiers de configuration, ainsi que les fichiers et les nœuds ZooKeeper utilisés lors des substitutions et des remplacements, et recharge les paramètres pour les utilisateurs et les clusters à la volée. Cela signifie que vous pouvez modifier le cluster, les utilisateurs et leurs paramètres sans redémarrer le serveur.

-# Surveiller {#monitoring}
-
-Vous pouvez surveiller:
-
--   L'utilisation des ressources matérielles.
--   Statistiques du serveur ClickHouse.
-
-## L'Utilisation Des Ressources {#resource-utilization}
-
-ClickHouse ne surveille pas l'état des ressources matérielles par lui-même.
-
-Il est fortement recommandé de configurer la surveillance de:
-
--   Charge et température sur les processeurs.
-
-    Vous pouvez utiliser [dmesg](https://en.wikipedia.org/wiki/Dmesg), [turbostat](https://www.linux.org/docs/man8/turbostat.html) ou d'autres instruments.
-
--   Utilisation du système de stockage, de la RAM et du réseau.
-
-## Métriques Du Serveur ClickHouse {#clickhouse-server-metrics}
-
-Clickhouse server a des instruments embarqués pour la surveillance de l'auto-état.
-
-Pour suivre les événements du serveur, utilisez les journaux du serveur. Voir la [enregistreur](server-configuration-parameters/settings.md#server_configuration_parameters-logger) section du fichier de configuration.
-
-Clickhouse recueille:
-
--   Différentes mesures de la façon dont le serveur utilise les ressources de calcul.
--   Statistiques communes sur le traitement des requêtes.
-
-Vous pouvez trouver des mesures dans le [système.métrique](../operations/system-tables.md#system_tables-metrics), [système.événement](../operations/system-tables.md#system_tables-events), et [système.asynchronous_metrics](../operations/system-tables.md#system_tables-asynchronous_metrics) table.
-
-Vous pouvez configurer ClickHouse pour exporter des métriques vers [Graphite](https://github.com/graphite-project). Voir la [Graphite section](server-configuration-parameters/settings.md#server_configuration_parameters-graphite) dans le fichier de configuration du serveur ClickHouse. Avant de configurer l'exportation des métriques, vous devez configurer Graphite en suivant leur [guide](https://graphite.readthedocs.io/en/latest/install.html).
-
-Vous pouvez configurer ClickHouse pour exporter des métriques vers [Prometheus](https://prometheus.io). Voir la [Prometheus section](server-configuration-parameters/settings.md#server_configuration_parameters-prometheus) dans le fichier de configuration du serveur ClickHouse. Avant de configurer l'exportation des métriques, vous devez configurer Prometheus en suivant leur [guide](https://prometheus.io/docs/prometheus/latest/installation/).
-
-De plus, vous pouvez surveiller la disponibilité du serveur via L'API HTTP. Envoyer la `HTTP GET` demande à `/ping`. Si le serveur est disponible, il répond avec `200 OK`.
-
-Pour surveiller les serveurs dans une configuration de cluster, vous devez [max_replica_delay_for_distributed_queries](settings/settings.md#settings-max_replica_delay_for_distributed_queries) paramètre et utiliser la ressource HTTP `/replicas_status`. Une demande de `/replicas_status` retourner `200 OK` si la réplique est disponible et n'est pas retardé derrière les autres réplicas. Si une réplique est retardée, elle revient `503 HTTP_SERVICE_UNAVAILABLE` avec des informations sur l'écart.

----
-
-# Échantillonnage Du Profileur De Requête {#sampling-query-profiler}
-
-ClickHouse exécute un profileur d'échantillonnage qui permet d'analyser l'exécution des requêtes. En utilisant profiler, vous pouvez trouver des routines de code source qui ont utilisé le plus fréquemment lors de l'exécution de la requête. Vous pouvez suivre le temps CPU et le temps d'horloge murale passé, y compris le temps d'inactivité.
-
-Utilisation du générateur de profils:
-
--   Installation de la [trace_log](../server-configuration-parameters/settings.md#server_configuration_parameters-trace_log) la section de la configuration du serveur.
-
-    Cette section configure le [trace_log](../../operations/system-tables.md#system_tables-trace_log) tableau système contenant les résultats du fonctionnement du profileur. Il est configuré par défaut. Rappelez-vous que les données de ce tableau est valable que pour un serveur en cours d'exécution. Après le redémarrage du serveur, ClickHouse ne nettoie pas la table et toute l'adresse de mémoire virtuelle stockée peut devenir invalide.
-
--   Installation de la [query_profiler_cpu_time_period_ns](../settings/settings.md#query_profiler_cpu_time_period_ns) ou [query_profiler_real_time_period_ns](../settings/settings.md#query_profiler_real_time_period_ns) paramètre. Les deux paramètres peuvent être utilisés simultanément.
-
-    Ces paramètres vous permettent de configurer les minuteries du profileur. Comme il s'agit des paramètres de session, vous pouvez obtenir une fréquence d'échantillonnage différente pour l'ensemble du serveur, les utilisateurs individuels ou les profils d'utilisateurs, pour votre session interactive et pour chaque requête individuelle.
-
-La fréquence d'échantillonnage par défaut est d'un échantillon par seconde et le processeur et les minuteries réelles sont activés. Cette fréquence permet de collecter suffisamment d'informations sur le cluster ClickHouse. En même temps, en travaillant avec cette fréquence, profiler n'affecte pas les performances du serveur ClickHouse. Si vous avez besoin de profiler chaque requête individuelle, essayez d'utiliser une fréquence d'échantillonnage plus élevée.
-
-Pour analyser les `trace_log` système de table:
-
--   Installer le `clickhouse-common-static-dbg` paquet. Voir [Installer à partir de paquets DEB](../../getting-started/install.md#install-from-deb-packages).
-
--   Autoriser les fonctions d'introspection par [allow_introspection_functions](../settings/settings.md#settings-allow_introspection_functions) paramètre.
-
-    Pour des raisons de sécurité, les fonctions d'introspection sont désactivées par défaut.
-
--   L'utilisation de la `addressToLine`, `addressToSymbol` et `demangle` [fonctions d'introspection](../../sql-reference/functions/introspection.md) pour obtenir les noms de fonctions et leurs positions dans le code ClickHouse. Pour obtenir un profil pour une requête, vous devez agréger les données du `trace_log` table. Vous pouvez agréger des données par des fonctions individuelles ou par l'ensemble des traces de la pile.
-
-Si vous avez besoin de visualiser `trace_log` info, essayez [flamegraph](../../interfaces/third-party/gui/#clickhouse-flamegraph) et [speedscope](https://github.com/laplab/clickhouse-speedscope).
-
-## Exemple {#example}
-
-Dans cet exemple, nous:
-
--   Filtrage `trace_log` données par un identifiant de requête et la date actuelle.
-
--   Agrégation par trace de pile.
-
--   En utilisant les fonctions d'introspection, nous obtiendrons un rapport de:
-
-    -   Noms des symboles et des fonctions de code source correspondantes.
-    -   Emplacements de code Source de ces fonctions.
-
-<!-- -->
-
-``` sql

-toc_title: Quota
----
-
-# Quota {#quotas}
-
-Les Quotas permettent de limiter l'utilisation des ressources au cours d'une période de temps ou de suivre l'utilisation des ressources.
-Les Quotas sont configurés dans la configuration utilisateur, qui est généralement ‘users.xml’.
-
-Le système dispose également d'une fonctionnalité pour limiter la complexité d'une seule requête. Voir la section “Restrictions on query complexity”).
-
-Contrairement aux restrictions de complexité des requêtes, les quotas:
-
--   Placez des restrictions sur un ensemble de requêtes qui peuvent être exécutées sur une période de temps, au lieu de limiter une seule requête.
--   Compte des ressources dépensées sur tous les serveurs distants pour le traitement des requêtes distribuées.
-
-Regardons la section de la ‘users.xml’ fichier qui définit les quotas.
-
-``` xml
-<!-- Quotas -->
-<quotas>
-    <!-- Quota name. -->
-    <default>
-        <!-- Restrictions for a time period. You can set many intervals with different restrictions. -->
-        <interval>
-            <!-- Length of the interval. -->
-            <duration>3600</duration>
-
-            <!-- Unlimited. Just collect data for the specified time interval. -->
-            <queries>0</queries>
-            <errors>0</errors>
-            <result_rows>0</result_rows>
-            <read_rows>0</read_rows>
-            <execution_time>0</execution_time>
-        </interval>
-    </default>
-```
-
-Par défaut, le quota suit la consommation de ressources pour chaque heure, sans limiter l'utilisation.
-La consommation de ressources calculé pour chaque intervalle est sortie dans le journal du serveur après chaque demande.
-
-``` xml
-<statbox>
-    <!-- Restrictions for a time period. You can set many intervals with different restrictions. -->
-    <interval>
-        <!-- Length of the interval. -->
-        <duration>3600</duration>
-
-        <queries>1000</queries>
-        <errors>100</errors>
-        <result_rows>1000000000</result_rows>
-        <read_rows>100000000000</read_rows>
-        <execution_time>900</execution_time>
-    </interval>
-
-    <interval>
-        <duration>86400</duration>
-
-        <queries>10000</queries>
-        <errors>1000</errors>
-        <result_rows>5000000000</result_rows>
-        <read_rows>500000000000</read_rows>
-        <execution_time>7200</execution_time>
-    </interval>
-</statbox>
-```
-
-Pour l' ‘statbox’ quota, restrictions sont fixées pour toutes les heures et pour toutes les 24 heures (86 400 secondes). L'intervalle de temps est compté, à partir d'un moment fixe défini par l'implémentation. En d'autres termes, l'intervalle de 24 heures ne commence pas nécessairement à minuit.
-
-Lorsque l'intervalle se termine, toutes les valeurs collectées sont effacées. Pour l'heure suivante, le calcul du quota recommence.
-
-Voici les montants qui peuvent être restreint:
-
-`queries` – The total number of requests.
-
-`errors` – The number of queries that threw an exception.
-
-`result_rows` – The total number of rows given as a result.
-
-`read_rows` – The total number of source rows read from tables for running the query on all remote servers.
-
-`execution_time` – The total query execution time, in seconds (wall time).
-
-Si la limite est dépassée pendant au moins un intervalle de temps, une exception est levée avec un texte indiquant quelle restriction a été dépassée, pour quel intervalle et quand le nouvel intervalle commence (lorsque les requêtes peuvent être envoyées à nouveau).
-
-Les Quotas peuvent utiliser le “quota key” fonctionnalité de rapport sur les ressources pour plusieurs clés indépendamment. Voici un exemple de ce:
-
-``` xml
-<!-- For the global reports designer. -->
-<web_global>
-    <!-- keyed – The quota_key "key" is passed in the query parameter,
-            and the quota is tracked separately for each key value.
-        For example, you can pass a Yandex.Metrica username as the key,
-            so the quota will be counted separately for each username.
-        Using keys makes sense only if quota_key is transmitted by the program, not by a user.
-
-        You can also write <keyed_by_ip />, so the IP address is used as the quota key.
-        (But keep in mind that users can change the IPv6 address fairly easily.)
-    -->
-    <keyed />
-```
-
-Le quota est attribué aux utilisateurs dans le ‘users’ section de la configuration. Voir la section “Access rights”.
-
-Pour le traitement des requêtes distribuées, les montants accumulés sont stockés sur le serveur demandeur. Donc, si l'utilisateur se rend sur un autre serveur, le quota y sera “start over”.
-
-Lorsque le serveur est redémarré, les quotas sont réinitialisés.

----
-
-# Exigence {#requirements}
-
-## CPU {#cpu}
-
-Pour l'installation à partir de paquets deb prédéfinis, utilisez un processeur avec l'architecture x86_64 et la prise en charge des instructions SSE 4.2. Pour exécuter ClickHouse avec des processeurs qui ne prennent pas en charge SSE 4.2 ou qui ont une architecture AArch64 ou PowerPC64LE, vous devez créer ClickHouse à partir de sources.
-
-ClickHouse implémente le traitement parallèle des données et utilise toutes les ressources matérielles disponibles. Lors du choix d'un processeur, tenez compte du fait que ClickHouse fonctionne plus efficacement dans les configurations avec un grand nombre de cœurs mais une fréquence d'horloge plus faible que dans les configurations avec moins de cœurs et une fréquence d'horloge plus élevée. Par exemple, 16 cœurs avec 2600 MHz est préférable à 8 cœurs avec 3600 MHz.
-
-Il est recommandé d'utiliser **Turbo Boost** et **la technologie hyper-threading** technologie. Il améliore considérablement les performances avec une charge de travail typique.
-
-## RAM {#ram}
-
-Nous vous recommandons d'utiliser un minimum de 4 Go de RAM pour effectuer des requêtes non triviales. Le serveur ClickHouse peut fonctionner avec une quantité beaucoup plus petite de RAM, mais il nécessite de la mémoire pour traiter les requêtes.
-
-Le volume de RAM requis dépend de:
-
--   La complexité des requêtes.
--   La quantité de données traitées dans les requêtes.
-
-Pour calculer le volume de RAM requis, vous devez estimer la taille des données temporaires pour [GROUP BY](../sql-reference/statements/select/group-by.md#select-group-by-clause), [DISTINCT](../sql-reference/statements/select/distinct.md#select-distinct), [JOIN](../sql-reference/statements/select/join.md#select-join) et d'autres opérations que vous utilisez.
-
-ClickHouse peut utiliser la mémoire externe pour les données temporaires. Voir [Groupe par dans la mémoire externe](../sql-reference/statements/select/group-by.md#select-group-by-in-external-memory) pour plus de détails.
-
-## Fichier D'Échange {#swap-file}
-
-Désactiver le fichier d'échange pour les environnements de production.
-
-## Sous-Système De Stockage {#storage-subsystem}
-
-Vous devez avoir 2 Go d'espace disque libre pour installer ClickHouse.
-
-Le volume de stockage requis pour vos données doit être calculé séparément. L'évaluation devrait inclure:
-
--   Estimation du volume de données.
-
-    Vous pouvez prendre un échantillon des données et obtenir la taille moyenne d'une ligne. Ensuite, multipliez la valeur par le nombre de lignes que vous souhaitez stocker.
-
--   Le coefficient de compression des données.
-
-    Pour estimer le coefficient de compression des données, chargez un échantillon de vos données dans ClickHouse et comparez la taille réelle des données avec la taille de la table stockée. Par exemple, les données de flux de clics sont généralement compressées de 6 à 10 fois.
-
-Pour calculer le volume final de données à stocker, appliquez le coefficient de compression au volume de données estimé. Si vous prévoyez de stocker des données dans plusieurs répliques, puis multipliez le volume estimé par le nombre de réplicas.
-
-## Réseau {#network}
-
-Si possible, utilisez des réseaux de classe 10G ou supérieure.
-
-La bande passante du réseau est essentielle pour traiter les requêtes distribuées avec une grande quantité de données intermédiaires. En outre, la vitesse du réseau affecte les processus de réplication.
-
-## Logiciel {#software}
-
-ClickHouse est développé principalement pour la famille de systèmes D'exploitation Linux. La distribution Linux recommandée est Ubuntu. Le `tzdata` paquet doit être installé dans le système.
-
-ClickHouse peut également fonctionner dans d'autres familles de systèmes d'exploitation. Voir les détails dans le [Prise en main](../getting-started/index.md) section de la documentation.

-`system.query_log`, `system.text_log`, `system.processes` table, et dans les journaux envoyés au client. Qui permet à la prévention de
-fuite de données sensibles à partir de requêtes SQL (comme les noms, e-mails,
-identificateurs ou numéros de carte de crédit) aux journaux.
-
-**Exemple**
-
-``` xml

-Spécifié comme identifiant IANA pour le fuseau horaire UTC ou l'emplacement géographique (par exemple, Afrique / Abidjan).
-
-Le fuseau horaire est nécessaire pour les conversions entre les formats String et DateTime lorsque les champs DateTime sont sortis au format texte (imprimés à l'écran ou dans un fichier) et lors de L'obtention de DateTime à partir d'une chaîne. En outre, le fuseau horaire est utilisé dans les fonctions qui fonctionnent avec l'heure et la date si elles ne reçoivent pas le fuseau horaire dans les paramètres d'entrée.

-
-``` xml
-<timezone>Europe/Moscow</timezone>
-```
-
-## tcp_port {#server_configuration_parameters-tcp_port}

-
-La politique de [`storage_configuration`](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes) pour stocker des fichiers temporaires.
-Si cela n'est pas [`tmp_path`](#server-settings-tmp_path) est utilisé, sinon elle est ignorée.
-
-!!! note "Note"

-
-Taille du Cache (en octets) pour les données non compressées utilisées par les [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md).
-
-Il y a un cache partagé pour le serveur. La mémoire est allouée à la demande. Le cache est utilisé si l'option [use_uncompressed_cache](../settings/settings.md#setting-use_uncompressed_cache) est activé.
-
-Le cache non compressé est avantageux pour les requêtes très courtes dans des cas individuels.
-
-**Exemple**
-

-```
-
-## zookeeper {#server-settings_zookeeper}
-
-Contient des paramètres qui permettent à ClickHouse d'interagir avec [ZooKeeper](http://zookeeper.apache.org/) cluster.
-
-ClickHouse utilise ZooKeeper pour stocker les métadonnées des répliques lors de l'utilisation de tables répliquées. Si les tables répliquées ne sont pas utilisées, cette section de paramètres peut être omise.
-
-Cette section contient les paramètres suivants:
-
--   `node` — ZooKeeper endpoint. You can set multiple endpoints.
-
-    Exemple:
-
-<!-- -->
-
-``` xml
-    <node index="1">
-        <host>example_host</host>
-        <port>2181</port>
-    </node>
-```
-
-      The `index` attribute specifies the node order when trying to connect to the ZooKeeper cluster.
-
--   `session_timeout` — Maximum timeout for the client session in milliseconds.
--   `root` — The [znode](http://zookeeper.apache.org/doc/r3.5.5/zookeeperOver.html#Nodes+and+ephemeral+nodes) qui est utilisé comme racine pour les znodes utilisés par le serveur ClickHouse. Facultatif.
--   `identity` — User and password, that can be required by ZooKeeper to give access to requested znodes. Optional.
-
-**Exemple de configuration**
-
-``` xml

-        <port>2181</port>
-    </node>
-    <session_timeout_ms>30000</session_timeout_ms>
-    <operation_timeout_ms>10000</operation_timeout_ms>
-    <!-- Optional. Chroot suffix. Should exist. -->
-    <root>/path/to/zookeeper/node</root>
-    <!-- Optional. Zookeeper digest ACL string. -->
-    <identity>user:password</identity>
-</zookeeper>

-
-## use_minimalistic_part_header_in_zookeeper {#server-settings-use_minimalistic_part_header_in_zookeeper}
-
-Méthode de stockage pour les en-têtes de partie de données dans ZooKeeper.
-
-Ce paramètre s'applique uniquement à l' `MergeTree` famille. Il peut être spécifié:
-
--   À l'échelle mondiale dans le [merge_tree](#server_configuration_parameters-merge_tree) la section de la `config.xml` fichier.
-
-    ClickHouse utilise le paramètre pour toutes les tables du serveur. Vous pouvez modifier le réglage à tout moment. Les tables existantes changent de comportement lorsque le paramètre change.
-
--   Pour chaque table.
-
-    Lors de la création d'un tableau, indiquer la [moteur de réglage](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table). Le comportement d'une table existante avec ce paramètre ne change pas, même si le paramètre global des changements.
-
-**Valeurs possibles**
-
--   0 — Functionality is turned off.
--   1 — Functionality is turned on.
-
-Si `use_minimalistic_part_header_in_zookeeper = 1`, puis [répliqué](../../engines/table-engines/mergetree-family/replication.md) les tables stockent les en-têtes des parties de données de manière compacte à l'aide `znode`. Si la table contient plusieurs colonnes, cette méthode de stockage réduit considérablement le volume des données stockées dans Zookeeper.
-
-!!! attention "Attention"
-    Après l'application de `use_minimalistic_part_header_in_zookeeper = 1`, vous ne pouvez pas rétrograder le serveur ClickHouse vers une version qui ne prend pas en charge ce paramètre. Soyez prudent lors de la mise à niveau de ClickHouse sur les serveurs d'un cluster. Ne mettez pas à niveau tous les serveurs à la fois. Il est plus sûr de tester de nouvelles versions de ClickHouse dans un environnement de test, ou sur quelques serveurs d'un cluster.
-
-      Data part headers already stored with this setting can't be restored to their previous (non-compact) representation.
-
-**Valeur par défaut:** 0.
-
-## disable_internal_dns_cache {#server-settings-disable-internal-dns-cache}
-
-Désactive le cache DNS interne. Recommandé pour l'utilisation de ClickHouse dans les systèmes
-avec des infrastructures en constante évolution telles que Kubernetes.
-
-**Valeur par défaut:** 0.
-
-## dns_cache_update_period {#server-settings-dns-cache-update-period}
-
-La période de mise à jour des adresses IP stockées dans le cache DNS interne de ClickHouse (en secondes).
-La mise à jour est effectuée de manière asynchrone, dans un thread système séparé.
-
-**Valeur par défaut**: 15.
-
-## access_control_path {#access_control_path}
-
-Chemin d'accès à un dossier dans lequel un serveur clickhouse stocke les configurations utilisateur et rôle créées par les commandes SQL.
-
-Valeur par défaut: `/var/lib/clickhouse/access/`.

----
-
-# Contraintes sur les paramètres {#constraints-on-settings}
-
-Les contraintes sur les paramètres peuvent être définis dans le `profiles` la section de la `user.xml` fichier de configuration et interdire aux utilisateurs de modifier certains `SET` requête.
-Les contraintes sont définies comme suit:
-
-``` xml
-<profiles>
-  <user_name>
-    <constraints>
-      <setting_name_1>
-        <min>lower_boundary</min>
-      </setting_name_1>
-      <setting_name_2>
-        <max>upper_boundary</max>
-      </setting_name_2>
-      <setting_name_3>
-        <min>lower_boundary</min>
-        <max>upper_boundary</max>
-      </setting_name_3>
-      <setting_name_4>
-        <readonly/>
-      </setting_name_4>
-    </constraints>
-  </user_name>
-</profiles>
-```
-
-Si l'utilisateur tente de violer les contraintes une exception est levée et le réglage n'est pas modifié.
-Trois types de contraintes sont pris en charge: `min`, `max`, `readonly`. Le `min` et `max` les contraintes spécifient les limites supérieure et inférieure pour un paramètre numérique et peuvent être utilisées en combinaison. Le `readonly` contrainte spécifie que l'utilisateur ne peut pas modifier le paramètre correspondant à tous.
-
-**Exemple:** Laisser `users.xml` comprend des lignes:
-
-``` xml
-<profiles>
-  <default>
-    <max_memory_usage>10000000000</max_memory_usage>
-    <force_index_by_date>0</force_index_by_date>
-    ...
-    <constraints>
-      <max_memory_usage>
-        <min>5000000000</min>
-        <max>20000000000</max>
-      </max_memory_usage>
-      <force_index_by_date>
-        <readonly/>
-      </force_index_by_date>
-    </constraints>
-  </default>
-</profiles>
-```
-
-Les requêtes suivantes toutes les exceptions throw:
-
-``` sql
-SET max_memory_usage=20000000001;
-SET max_memory_usage=4999999999;
-SET force_index_by_date=1;
-```
-
-``` text
-Code: 452, e.displayText() = DB::Exception: Setting max_memory_usage should not be greater than 20000000000.
-Code: 452, e.displayText() = DB::Exception: Setting max_memory_usage should not be less than 5000000000.
-Code: 452, e.displayText() = DB::Exception: Setting force_index_by_date should not be changed.
-```
-
-**Note:** le `default` le profil a une manipulation particulière: toutes les contraintes définies pour `default` le profil devient les contraintes par défaut, de sorte qu'ils restreignent tous les utilisateurs jusqu'à ce qu'ils soient explicitement remplacés pour ces utilisateurs.

-# Paramètre {#session-settings-intro}
-
-Il existe plusieurs façons d'effectuer tous les paramètres décrits dans cette section de la documentation.
-
-Les paramètres sont configurés en couches, de sorte que chaque couche suivante redéfinit les paramètres précédents.
-
-Façons de configurer les paramètres, par ordre de priorité:
-
--   Paramètres dans l' `users.xml` fichier de configuration du serveur.
-
-    Situé dans l'élément `<profiles>`.
-
--   Les paramètres de la Session.
-
-    Envoyer `SET setting=value` depuis le client de la console ClickHouse en mode interactif.
-    De même, vous pouvez utiliser des sessions ClickHouse dans le protocole HTTP. Pour ce faire, vous devez spécifier le `session_id` Paramètre HTTP.
-
--   Les paramètres de requête.
-
-    -   Lorsque vous démarrez le client clickhouse console en mode non interactif, définissez le paramètre startup `--setting=value`.
-    -   Lors de l'utilisation de L'API HTTP, passez les paramètres CGI (`URL?setting_1=value&setting_2=value...`).
-
-Les paramètres qui ne peuvent être effectués que dans le fichier de configuration du serveur ne sont pas couverts dans cette section.

----
-
-# Autorisations pour les requêtes {#permissions_for_queries}
-
-Les requêtes dans ClickHouse peuvent être divisées en plusieurs types:
-
-1.  Lire les requêtes de données: `SELECT`, `SHOW`, `DESCRIBE`, `EXISTS`.
-2.  Écrire des requêtes de données: `INSERT`, `OPTIMIZE`.
-3.  Modifier les paramètres requête: `SET`, `USE`.
-4.  [DDL](https://en.wikipedia.org/wiki/Data_definition_language) requête: `CREATE`, `ALTER`, `RENAME`, `ATTACH`, `DETACH`, `DROP` `TRUNCATE`.
-5.  `KILL QUERY`.
-
-Les paramètres suivants règlent les autorisations utilisateur selon le type de requête:
-
--   [ReadOnly](#settings_readonly) — Restricts permissions for all types of queries except DDL queries.
--   [allow_ddl](#settings_allow_ddl) — Restricts permissions for DDL queries.
-
-`KILL QUERY` peut être réalisée avec tous les paramètres.
-
-## ReadOnly {#settings_readonly}
-
-Restreint les autorisations pour lire des données, écrire des données et modifier les requêtes de paramètres.
-
-Voyez comment les requêtes sont divisées en types [surtout](#permissions_for_queries).
-
-Valeurs possibles:
-
--   0 — All queries are allowed.
--   1 — Only read data queries are allowed.
--   2 — Read data and change settings queries are allowed.
-
-Après le réglage de `readonly = 1` l'utilisateur ne peut pas changer `readonly` et `allow_ddl` les paramètres de la session en cours.
-
-Lors de l'utilisation de la `GET` méthode dans le [Interface HTTP](../../interfaces/http.md), `readonly = 1` est définie automatiquement. Pour modifier les données, utilisez `POST` méthode.
-
-Paramètre `readonly = 1` interdire à l'utilisateur de modifier tous les paramètres. Il y a un moyen d'interdire à l'utilisateur
-de modifier uniquement des paramètres spécifiques, pour plus de détails, voir [contraintes sur les paramètres](constraints-on-settings.md).
-
-Valeur par défaut: 0
-
-## allow_ddl {#settings_allow_ddl}
-
-Permet ou interdit [DDL](https://en.wikipedia.org/wiki/Data_definition_language) requête.
-
-Voyez comment les requêtes sont divisées en types [surtout](#permissions_for_queries).
-
-Valeurs possibles:
-
--   0 — DDL queries are not allowed.
--   1 — DDL queries are allowed.
-
-Vous ne pouvez pas exécuter `SET allow_ddl = 1` si `allow_ddl = 0` pour la session en cours.
-
-Valeur par défaut: 1

-toc_title: "Restrictions sur la complexit\xE9 des requ\xEAtes"
----
-
-# Restrictions sur la complexité des requêtes {#restrictions-on-query-complexity}
-
-Les Restrictions sur la complexité des requêtes font partie des paramètres.
-Ils sont utilisés pour fournir une exécution plus sûre à partir de l'interface utilisateur.
-Presque toutes les restrictions ne s'appliquent qu'à `SELECT`. Pour le traitement des requêtes distribuées, des restrictions sont appliquées sur chaque serveur séparément.
-
-ClickHouse vérifie les restrictions pour les parties de données, pas pour chaque ligne. Cela signifie que vous pouvez dépasser la valeur de restriction de la taille de la partie données.
-
-Restrictions sur l' “maximum amount of something” peut prendre la valeur 0, ce qui signifie “unrestricted”.
-La plupart des restrictions ont également un ‘overflow_mode’ paramètre signification que faire lorsque la limite est dépassée.
-Il peut prendre deux valeurs: `throw` ou `break`. Les Restrictions sur l'agrégation (group_by_overflow_mode) ont également la valeur `any`.
-
-`throw` – Throw an exception (default).
-
-`break` – Stop executing the query and return the partial result, as if the source data ran out.
-
-`any (only for group_by_overflow_mode)` – Continuing aggregation for the keys that got into the set, but don't add new keys to the set.
-
-## max_memory_usage {#settings_max_memory_usage}
-
-La quantité maximale de RAM à utiliser pour exécuter une requête sur un seul serveur.
-
-Dans le fichier de configuration par défaut, le maximum est de 10 Go.
-
-Le réglage ne tient pas compte du volume de mémoire disponible ou du volume total de mémoire sur la machine.
-La restriction s'applique à une seule requête au sein d'un seul serveur.
-Vous pouvez utiliser `SHOW PROCESSLIST` pour vérifier la consommation de mémoire pour chaque requête.
-En outre, la consommation de mémoire maximale est suivie pour chaque requête et écrite dans le journal.
-
-L'utilisation de la mémoire n'est pas surveillée pour les membres de certaines fonctions d'agrégation.
-
-L'utilisation de la mémoire n'est pas totalement suivies pour les états des fonctions d'agrégation `min`, `max`, `any`, `anyLast`, `argMin`, `argMax` de `String` et `Array` argument.
-
-La consommation de mémoire est également limitée par les paramètres `max_memory_usage_for_user` et `max_memory_usage_for_all_queries`.
-
-## max_memory_usage_for_user {#max-memory-usage-for-user}
-
-Quantité maximale de RAM à utiliser pour exécuter les requêtes d'un utilisateur sur un seul serveur.
-
-Les valeurs par défaut sont définies dans [Paramètre.h](https://github.com/ClickHouse/ClickHouse/blob/master/src/Core/Settings.h#L288). Par défaut, le montant n'est pas limité (`max_memory_usage_for_user = 0`).
-
-Voir aussi la description de [max_memory_usage](#settings_max_memory_usage).
-
-## max_memory_usage_for_all_queries {#max-memory-usage-for-all-queries}
-
-La quantité maximale de RAM à utiliser pour exécuter toutes les requêtes sur un seul serveur.
-
-Les valeurs par défaut sont définies dans [Paramètre.h](https://github.com/ClickHouse/ClickHouse/blob/master/src/Core/Settings.h#L289). Par défaut, le montant n'est pas limité (`max_memory_usage_for_all_queries = 0`).
-
-Voir aussi la description de [max_memory_usage](#settings_max_memory_usage).
-
-## max_rows_to_read {#max-rows-to-read}
-
-Les restrictions suivantes peut être vérifiée sur chaque bloc (au lieu de sur chaque ligne). Autrement dit, les restrictions peuvent être brisées un peu.
-Lors de l'exécution d'une requête dans plusieurs threads, les restrictions suivantes s'appliquent à chaque thread séparément.
-
-Un nombre maximum de lignes pouvant être lues à partir d'un tableau lors de l'exécution d'une requête.
-
-## max_bytes_to_read {#max-bytes-to-read}
-
-Nombre maximal d'octets (données non compressées) pouvant être lus à partir d'une table lors de l'exécution d'une requête.
-
-## read_overflow_mode {#read-overflow-mode}
-
-Que faire lorsque le volume de lecture de données dépasse l'une des limites: ‘throw’ ou ‘break’. Par défaut, les jeter.
-
-## max_rows_to_group_by {#settings-max-rows-to-group-by}
-
-Un nombre maximum de clés uniques reçues de l'agrégation. Ce paramètre permet de limiter la consommation de mémoire lors de l'agrégation.
-
-## group_by_overflow_mode {#group-by-overflow-mode}
-
-Que faire lorsque le nombre de clés uniques pour l'agrégation dépasse la limite: ‘throw’, ‘break’, ou ‘any’. Par défaut, les jeter.
-À l'aide de la ‘any’ valeur vous permet d'exécuter une approximation de GROUP BY. La qualité de cette approximation dépend de la nature statistique des données.
-
-## max_bytes_before_external_group_by {#settings-max_bytes_before_external_group_by}
-
-Active ou désactive l'exécution de `GROUP BY` clauses dans la mémoire externe. Voir [Groupe par dans la mémoire externe](../../sql-reference/statements/select/group-by.md#select-group-by-in-external-memory).
-
-Valeurs possibles:
-
--   Volume maximal de RAM (en octets) pouvant être utilisé par le [GROUP BY](../../sql-reference/statements/select/group-by.md#select-group-by-clause) opération.
--   0 — `GROUP BY` dans la mémoire externe désactivé.
-
-Valeur par défaut: 0.
-
-## max_rows_to_sort {#max-rows-to-sort}
-
-Un nombre maximum de lignes avant le tri. Cela vous permet de limiter la consommation de mémoire lors du tri.
-
-## max_bytes_to_sort {#max-bytes-to-sort}
-
-Un nombre maximal d'octets avant le tri.
-
-## sort_overflow_mode {#sort-overflow-mode}
-
-Que faire si le nombre de lignes reçues avant le tri dépasse l'une des limites: ‘throw’ ou ‘break’. Par défaut, les jeter.
-
-## max_result_rows {#setting-max_result_rows}
-
-Limite sur le nombre de lignes dans le résultat. Également vérifié pour les sous-requêtes, et sur des serveurs distants lors de l'exécution de parties d'une requête distribuée.
-
-## max_result_bytes {#max-result-bytes}
-
-Limite sur le nombre d'octets dans le résultat. Le même que le réglage précédent.
-
-## result_overflow_mode {#result-overflow-mode}
-
-Que faire si le volume du résultat dépasse l'une des limites: ‘throw’ ou ‘break’. Par défaut, les jeter.
-
-Utiliser ‘break’ est similaire à L'utilisation de LIMIT. `Break` interrompt l'exécution seulement au niveau du bloc. Cela signifie que la quantité de lignes renvoyées est supérieure à [max_result_rows](#setting-max_result_rows) multiples de [max_block_size](settings.md#setting-max_block_size) et dépend de l' [max_threads](settings.md#settings-max_threads).
-
-Exemple:
-
-``` sql
-SET max_threads = 3, max_block_size = 3333;
-SET max_result_rows = 3334, result_overflow_mode = 'break';
-
-SELECT *
-FROM numbers_mt(100000)
-FORMAT Null;
-```
-
-Résultat:
-
-``` text
-6666 rows in set. ...
-```
-
-## max_execution_time {#max-execution-time}
-
-Durée maximale d'exécution de la requête en secondes.
-Pour le moment, il n'est pas vérifié pour l'une des étapes de tri, ni lors de la fusion et de la finalisation des fonctions d'agrégat.
-
-## timeout_overflow_mode {#timeout-overflow-mode}
-
-Que faire si la requête est exécutée plus de ‘max_execution_time’: ‘throw’ ou ‘break’. Par défaut, les jeter.
-
-## min_execution_speed {#min-execution-speed}
-
-Vitesse d'exécution minimale en lignes par seconde. Vérifié sur chaque bloc de données quand ‘timeout_before_checking_execution_speed’ expirer. Si la vitesse d'exécution est inférieure, une exception est levée.
-
-## min_execution_speed_bytes {#min-execution-speed-bytes}
-
-Un nombre minimum d'exécution d'octets par seconde. Vérifié sur chaque bloc de données quand ‘timeout_before_checking_execution_speed’ expirer. Si la vitesse d'exécution est inférieure, une exception est levée.
-
-## max_execution_speed {#max-execution-speed}

-
-Valeur par défaut: 100.
-
-**Détail**
-
-Lors de l'insertion de données, ClickHouse calcule le nombre de partitions dans le bloc inséré. Si le nombre de partitions est plus que `max_partitions_per_insert_block`, ClickHouse lève une exception avec le texte suivant:
-
-> “Too many partitions for single INSERT block (more than” + toString (max_parts) + “). The limit is controlled by ‘max_partitions_per_insert_block’ setting. A large number of partitions is a common misconception. It will lead to severe negative performance impact, including slow server startup, slow INSERT queries and slow SELECT queries. Recommended total number of partitions for a table is under 1000..10000. Please note, that partitioning is not intended to speed up SELECT queries (ORDER BY key is sufficient to make range queries fast). Partitions are intended for data manipulation (DROP PARTITION, etc).”

-# Les Paramètres Des Profils {#settings-profiles}
-
-Un profil de paramètres est une collection de paramètres regroupés sous le même nom.
-
-!!! note "Information"
-    Clickhouse prend également en charge [Flux de travail piloté par SQL](../access-rights.md#access-control) pour gérer les profils de paramètres. Nous vous conseillons de l'utiliser.
-
-Un profil peut avoir n'importe quel nom. Le profil peut avoir n'importe quel nom. Vous pouvez spécifier le même profil pour différents utilisateurs. La chose la plus importante que vous pouvez écrire dans les paramètres de profil `readonly=1` qui assure un accès en lecture seule.
-
-Paramètres les profils peuvent hériter les uns des autres. Pour utiliser l'héritage, indiquer un ou plusieurs `profile` paramètres avant les autres paramètres répertoriés dans le profil. Dans le cas où un paramètre est défini dans les différents profils, les dernières définie est utilisée.
-
-Pour appliquer tous les paramètres d'un profil, définissez `profile` paramètre.
-
-Exemple:
-
-Installer le `web` profil.
-
-``` sql
-SET profile = 'web'
-```
-
-Les profils de paramètres sont déclarés dans le fichier de configuration utilisateur. Ce n'est généralement `users.xml`.
-
-Exemple:
-
-``` xml
-<!-- Settings profiles -->
-<profiles>
-    <!-- Default settings -->
-    <default>
-        <!-- The maximum number of threads when running a single query. -->
-        <max_threads>8</max_threads>
-    </default>
-
-    <!-- Settings for quries from the user interface -->
-    <web>
-        <max_rows_to_read>1000000000</max_rows_to_read>

-        <max_bytes_to_sort>1000000000</max_bytes_to_sort>
-
-        <max_result_rows>100000</max_result_rows>
-        <max_result_bytes>100000000</max_result_bytes>
-        <result_overflow_mode>break</result_overflow_mode>
-
-        <max_execution_time>600</max_execution_time>
-        <min_execution_speed>1000000</min_execution_speed>
-        <timeout_before_checking_execution_speed>15</timeout_before_checking_execution_speed>
-
-        <max_columns_to_read>25</max_columns_to_read>
-        <max_temporary_columns>100</max_temporary_columns>
-        <max_temporary_non_const_columns>50</max_temporary_non_const_columns>
-
-        <max_subquery_depth>2</max_subquery_depth>
-        <max_pipeline_depth>25</max_pipeline_depth>
-        <max_ast_depth>50</max_ast_depth>
-        <max_ast_elements>100</max_ast_elements>
-
-        <readonly>1</readonly>
-    </web>
-</profiles>
-```
-
-L'exemple spécifie deux profils: `default` et `web`.
-
-Le `default` profil a un but particulier: il doit toujours être présent et est appliquée lors du démarrage du serveur. En d'autres termes, l' `default` profil contient les paramètres par défaut.
-
-Le `web` profil est un profil régulier qui peut être défini à l'aide `SET` requête ou en utilisant un paramètre URL dans une requête HTTP.

-
-### nom_utilisateur/mot de passe {#user-namepassword}
-
-Le mot de passe peut être spécifié en texte clair ou en SHA256 (format hexadécimal).
-
--   Pour attribuer un mot de passe en clair (**pas recommandé**), la placer dans un `password` élément.
-
-    Exemple, `<password>qwerty</password>`. Le mot de passe peut être laissé en blanc.
-
-<a id="password_sha256_hex"></a>
-
--   Pour attribuer un mot de passe à l'aide de son hachage SHA256, placez-le dans un `password_sha256_hex` élément.
-
-    Exemple, `<password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex>`.

-    Exemple de génération d'un mot de passe à partir du shell:
-
-          PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
-
-    La première ligne du résultat est le mot de passe. La deuxième ligne est le hachage SHA256 correspondant.
-
-<a id="password_double_sha1_hex"></a>
-
--   Pour la compatibilité avec les clients MySQL, le mot de passe peut être spécifié dans le hachage double SHA1. Le placer dans `password_double_sha1_hex` élément.
-
-    Exemple, `<password_double_sha1_hex>08b4a0f1de6ad37da17359e592c8d74788a83eb0</password_double_sha1_hex>`.

-    La première ligne du résultat est le mot de passe. La deuxième ligne est le double hachage SHA1 correspondant.
-
-### access_management {#access_management-user-setting}
-
-Ce paramètre active de désactive l'utilisation de SQL-driven [le contrôle d'accès et de gestion de compte](../access-rights.md#access-control) pour l'utilisateur.
-
-Valeurs possibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valeur par défaut: 0.
-
-### nom_utilisateur / réseaux {#user-namenetworks}
-
-Liste des réseaux à partir desquels L'utilisateur peut se connecter au serveur ClickHouse.
-
-Chaque élément de la liste peut avoir l'une des formes suivantes:
-
--   `<ip>` — IP address or network mask.
-
-    Exemple: `213.180.204.3`, `10.0.0.1/8`, `10.0.0.1/255.255.255.0`, `2a02:6b8::3`, `2a02:6b8::3/64`, `2a02:6b8::3/ffff:ffff:ffff:ffff::`.
-
--   `<host>` — Hostname.
-
-    Exemple: `example01.host.ru`.
-
-    Pour vérifier l'accès, une requête DNS est effectuée et toutes les adresses IP renvoyées sont comparées à l'adresse homologue.
-
--   `<host_regexp>` — Regular expression for hostnames.
-
-    Exemple, `^example\d\d-\d\d-\d\.host\.ru$`
-
-    Pour vérifier l'accès, un [Requête DNS PTR](https://en.wikipedia.org/wiki/Reverse_DNS_lookup) est effectuée pour l'adresse homologue, puis l'expression rationnelle spécifiée est appliquée. Ensuite, une autre requête DNS est effectuée pour les résultats de la requête PTR et toutes les adresses reçues sont comparées à l'adresse homologue. Nous recommandons fortement que regexp se termine avec $.
-
-Tous les résultats des requêtes DNS sont mis en cache jusqu'au redémarrage du serveur.
-
-**Exemple**
-
-Pour ouvrir l'accès de l'utilisateur à partir de n'importe quel réseau, spécifiez:
-
-``` xml
-<ip>::/0</ip>
-```
-
-!!! warning "Avertissement"
-    Il n'est pas sûr d'ouvrir l'accès à partir de n'importe quel réseau, sauf si vous avez un pare-feu correctement configuré ou si le serveur n'est pas directement connecté à Internet.
-
-Pour ouvrir l'accès uniquement à partir de localhost, spécifier:
-
-``` xml
-<ip>::1</ip>
-<ip>127.0.0.1</ip>
-```
-
-### nom_utilisateur / profil {#user-nameprofile}
-
-Vous pouvez attribuer un profil des paramètres pour l'utilisateur. Les profils de paramètres sont configurés dans une section distincte du `users.xml` fichier. Pour plus d'informations, voir [Profils des paramètres](settings-profiles.md).
-
-### nom_utilisateur / quota {#user-namequota}
-
-Les Quotas vous permettent de suivre ou de limiter l'utilisation des ressources sur une période donnée. Les Quotas sont configurés dans le `quotas`
-la section de la `users.xml` fichier de configuration.
-
-Vous pouvez attribuer un jeu de quotas à l'utilisateur. Pour une description détaillée de la configuration des quotas, voir [Quota](../quotas.md#quotas).
-
-### nom_utilisateur/bases de données {#user-namedatabases}
-
-Dans cette section, vous pouvez limiter les lignes renvoyées par ClickHouse pour `SELECT` requêtes faites par l'utilisateur actuel, implémentant ainsi la sécurité de base au niveau de la ligne.
-
-**Exemple**
-
-La configuration suivante force cet utilisateur `user1` ne peut voir les lignes de `table1` comme le résultat de `SELECT` requêtes, où la valeur de la `id` le champ est 1000.
-
-``` xml
-<user1>
-    <databases>
-        <database_name>
-            <table1>
-                <filter>id = 1000</filter>
-            </table1>
-        </database_name>
-    </databases>
-</user1>
-```
-
-Le `filter` peut être n'importe quelle expression résultant en un [UInt8](../../sql-reference/data-types/int-uint.md)-le type de la valeur. Il contient généralement des comparaisons et des opérateurs logiques. Les lignes de `database_name.table1` où filtrer les résultats à 0 ne sont pas retournés pour cet utilisateur. Le filtrage est incompatible avec `PREWHERE` opérations et désactive `WHERE→PREWHERE` optimisation.

-# Paramètre {#settings}
-
-## distributed_product_mode {#distributed-product-mode}
-
-Modifie le comportement de [distribués sous-requêtes](../../sql-reference/operators/in.md).
-
-ClickHouse applies this setting when the query contains the product of distributed tables, i.e. when the query for a distributed table contains a non-GLOBAL subquery for the distributed table.
-
-Restriction:
-
--   Uniquement appliqué pour les sous-requêtes IN et JOIN.
--   Uniquement si la section FROM utilise une table distribuée contenant plus d'un fragment.
--   Si la sous-requête concerne un distribué tableau contenant plus d'un fragment.
--   Pas utilisé pour une table [distant](../../sql-reference/table-functions/remote.md) fonction.
-
-Valeurs possibles:
-
--   `deny` — Default value. Prohibits using these types of subqueries (returns the “Double-distributed in/JOIN subqueries is denied” exception).
--   `local` — Replaces the database and table in the subquery with local ones for the destination server (shard), leaving the normal `IN`/`JOIN.`
--   `global` — Replaces the `IN`/`JOIN` requête avec `GLOBAL IN`/`GLOBAL JOIN.`
--   `allow` — Allows the use of these types of subqueries.
-
-## enable_optimize_predicate_expression {#enable-optimize-predicate-expression}
-
-Active la poussée du prédicat `SELECT` requête.
-
-Prédicat pushdown peut réduire considérablement le trafic réseau pour les requêtes distribuées.
-
-Valeurs possibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valeur par défaut: 1.
-
-Utilisation
-
-Considérez les requêtes suivantes:
-
-1.  `SELECT count() FROM test_table WHERE date = '2018-10-10'`
-2.  `SELECT count() FROM (SELECT * FROM test_table) WHERE date = '2018-10-10'`
-
-Si `enable_optimize_predicate_expression = 1`, alors le temps d'exécution de ces requêtes est égal car ClickHouse s'applique `WHERE` à la sous-requête lors du traitement.
-
-Si `enable_optimize_predicate_expression = 0` puis le temps d'exécution de la deuxième requête est beaucoup plus long, parce que le `WHERE` la clause s'applique à toutes les données après la sous-requête des finitions.
-
-## fallback_to_stale_replicas_for_distributed_queries {#settings-fallback_to_stale_replicas_for_distributed_queries}
-
-Force une requête à un réplica obsolète si les données mises à jour ne sont pas disponibles. Voir [Réplication](../../engines/table-engines/mergetree-family/replication.md).
-
-ClickHouse sélectionne le plus pertinent parmi les répliques obsolètes de la table.
-
-Utilisé lors de l'exécution `SELECT` à partir d'une table distribuée qui pointe vers des tables répliquées.
-
-Par défaut, 1 (activé).
-
-## force_index_by_date {#settings-force_index_by_date}
-
-Désactive l'exécution de la requête si l'index ne peut pas être utilisé par jour.
-
-Fonctionne avec les tables de la famille MergeTree.
-
-Si `force_index_by_date=1`, Clickhouse vérifie si la requête a une condition de clé de date qui peut être utilisée pour restreindre les plages de données. S'il n'y a pas de condition appropriée, il lève une exception. Cependant, il ne vérifie pas si la condition réduit la quantité de données à lire. Par exemple, la condition `Date != ' 2000-01-01 '` est acceptable même lorsqu'il correspond à toutes les données de la table (c'est-à-dire que l'exécution de la requête nécessite une analyse complète). Pour plus d'informations sur les plages de données dans les tables MergeTree, voir [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md).
-
-## force_primary_key {#force-primary-key}
-
-Désactive l'exécution de la requête si l'indexation par la clé primaire n'est pas possible.
-
-Fonctionne avec les tables de la famille MergeTree.
-
-Si `force_primary_key=1`, Clickhouse vérifie si la requête a une condition de clé primaire qui peut être utilisée pour restreindre les plages de données. S'il n'y a pas de condition appropriée, il lève une exception. Cependant, il ne vérifie pas si la condition réduit la quantité de données à lire. Pour plus d'informations sur les plages de données dans les tables MergeTree, voir [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md).
-
-## format_schema {#format-schema}
-
-Ce paramètre est utile lorsque vous utilisez des formats nécessitant une définition de schéma, tels que [Cap'n Proto](https://capnproto.org/) ou [Protobuf](https://developers.google.com/protocol-buffers/). La valeur dépend du format.
-
-## fsync_metadata {#fsync-metadata}
-
-Active ou désactive [fsync](http://pubs.opengroup.org/onlinepubs/9699919799/functions/fsync.html) lors de l'écriture `.sql` fichier. Activé par défaut.
-
-Il est logique de le désactiver si le serveur a des millions de tables minuscules qui sont constamment créées et détruites.
-
-## enable_http_compression {#settings-enable_http_compression}
-
-Active ou désactive la compression de données dans la réponse à une requête HTTP.
-
-Pour plus d'informations, lire l' [Description de L'interface HTTP](../../interfaces/http.md).
-
-Valeurs possibles:
-
--   0 — Disabled.

-## input_format_values_interpret_expressions {#settings-input_format_values_interpret_expressions}
-
-Active ou désactive L'analyseur SQL complet si l'analyseur de flux rapide ne peut pas analyser les données. Ce paramètre est utilisé uniquement pour la [Valeur](../../interfaces/formats.md#data-format-values) format lors de l'insertion des données. Pour plus d'informations sur l'analyse syntaxique, consultez [Syntaxe](../../sql-reference/syntax.md) section.
-
-Valeurs possibles:
-
--   0 — Disabled.
-
-    Dans ce cas, vous devez fournir des données formatées. Voir la [Format](../../interfaces/formats.md) section.
-
--   1 — Enabled.
-
-    Dans ce cas, vous pouvez utiliser une expression SQL en tant que valeur, mais l'insertion de données est beaucoup plus lente de cette façon. Si vous insérez uniquement des données formatées, ClickHouse se comporte comme si la valeur de réglage était 0.
-
-Valeur par défaut: 1.
-
-Exemple D'utilisation
-
-Insérez le [DateTime](../../sql-reference/data-types/datetime.md) tapez valeur avec les différents paramètres.
-
-``` sql
-SET input_format_values_interpret_expressions = 0;
-INSERT INTO datetime_t VALUES (now())
-```
-
-``` text
-Exception on client:
-Code: 27. DB::Exception: Cannot parse input: expected ) before: now()): (at row 1)
-```
-
-``` sql
-SET input_format_values_interpret_expressions = 1;
-INSERT INTO datetime_t VALUES (now())
-```
-
-``` text
-Ok.
-```
-
-La dernière requête est équivalente à la suivante:
-
-``` sql
-SET input_format_values_interpret_expressions = 0;
-INSERT INTO datetime_t SELECT now()
-```
-
-``` text
-Ok.
-```
-
-## input_format_values_deduce_templates_of_expressions {#settings-input_format_values_deduce_templates_of_expressions}
-
-Active ou désactive la déduction de modèle pour les expressions SQL dans [Valeur](../../interfaces/formats.md#data-format-values) format. Il permet d'analyser et d'interpréter des expressions dans `Values` beaucoup plus rapide si les expressions dans des lignes consécutives ont la même structure. ClickHouse tente de déduire le modèle d'une expression, d'analyser les lignes suivantes à l'aide de ce modèle et d'évaluer l'expression sur un lot de lignes analysées avec succès.
-
-Valeurs possibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valeur par défaut: 1.
-
-Pour la requête suivante:
-
-``` sql
-INSERT INTO test VALUES (lower('Hello')), (lower('world')), (lower('INSERT')), (upper('Values')), ...
-```
-
--   Si `input_format_values_interpret_expressions=1` et `format_values_deduce_templates_of_expressions=0`, les expressions sont interprétées séparément pour chaque ligne (c'est très lent pour un grand nombre de lignes).
--   Si `input_format_values_interpret_expressions=0` et `format_values_deduce_templates_of_expressions=1`, les expressions des première, deuxième et troisième lignes sont analysées à l'aide de template `lower(String)` et interprété ensemble, l'expression dans la quatrième ligne est analysée avec un autre modèle (`upper(String)`).
--   Si `input_format_values_interpret_expressions=1` et `format_values_deduce_templates_of_expressions=1`, le même que dans le cas précédent, mais permet également d'interpréter les expressions séparément s'il n'est pas possible de déduire le modèle.
-
-## input_format_values_accurate_types_of_literals {#settings-input-format-values-accurate-types-of-literals}
-
-Ce paramètre est utilisé uniquement lorsque `input_format_values_deduce_templates_of_expressions = 1`. Il peut arriver que les expressions pour une colonne aient la même structure, mais contiennent des littéraux numériques de types différents, par exemple
-
-``` sql
-(..., abs(0), ...),             -- UInt64 literal
-(..., abs(3.141592654), ...),   -- Float64 literal
-(..., abs(-1), ...),            -- Int64 literal
-```
-
-Valeurs possibles:
-
--   0 — Disabled.
-
-    In this case, ClickHouse may use a more general type for some literals (e.g., `Float64` ou `Int64` plutôt `UInt64` pour `42`), mais cela peut causer des problèmes de débordement et de précision.
-
--   1 — Enabled.
-
-    Dans ce cas, ClickHouse vérifie le type réel de littéral et utilise un modèle d'expression du type correspondant. Dans certains cas, cela peut considérablement ralentir l'évaluation de l'expression dans `Values`.
-
-Valeur par défaut: 1.

-
-## max_block_size {#setting-max_block_size}
-
-Dans ClickHouse, les données sont traitées par Blocs (Ensembles de parties de colonne). Les cycles de traitement internes pour un seul bloc sont assez efficaces, mais il y a des dépenses notables sur chaque bloc. Le `max_block_size` le paramètre est une recommandation pour la taille du bloc (dans un nombre de lignes) à charger à partir des tables. La taille du bloc ne doit pas être trop petite, de sorte que les dépenses sur chaque bloc sont toujours perceptibles, mais pas trop grande pour que la requête avec limite qui est terminée après le premier bloc soit traitée rapidement. L'objectif est d'éviter de consommer trop de mémoire lors de l'extraction d'un grand nombre de colonnes dans plusieurs threads et de préserver au moins certains localité de cache.
-
-Valeur par défaut: de 65 536.
-
-Les blocs de la taille de `max_block_size` ne sont pas toujours chargées de la table. Si il est évident que moins de données doivent être récupérées, un bloc plus petit est traitée.
-
-## preferred_block_size_bytes {#preferred-block-size-bytes}
-
-Utilisé dans le même but que `max_block_size`, mais il définit la taille de bloc recommandée en octets en l'adaptant au nombre de lignes dans le bloc.
-Cependant, la taille du bloc ne peut pas être supérieure à `max_block_size` rangée.
-Par défaut: 1 000 000. Cela ne fonctionne que lors de la lecture des moteurs MergeTree.
-
-## merge_tree_min_rows_for_concurrent_read {#setting-merge-tree-min-rows-for-concurrent-read}
-
-Si le nombre de lignes à lire à partir d'un fichier d'un [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) table dépasse `merge_tree_min_rows_for_concurrent_read` ensuite, ClickHouse essaie d'effectuer une lecture simultanée de ce fichier sur plusieurs threads.

-
-Valeur par défaut: 0.
-
-## merge_tree_coarse_index_granularité {#setting-merge-tree-coarse-index-granularity}
-
-Lors de la recherche de données, ClickHouse vérifie les marques de données dans le fichier d'index. Si ClickHouse trouve que les clés requises sont dans une certaine plage, il divise cette plage en `merge_tree_coarse_index_granularity` subranges et recherche les clés requises récursivement.
-

-## merge_tree_max_rows_to_use_cache {#setting-merge-tree-max-rows-to-use-cache}
-
-Si ClickHouse devrait lire plus de `merge_tree_max_rows_to_use_cache` lignes dans une requête, il n'utilise pas le cache des blocs non compressés.
-
-Le cache des blocs non compressés stocke les données extraites pour les requêtes. ClickHouse utilise ce cache pour accélérer les réponses aux petites requêtes répétées. Ce paramètre protège le cache contre le saccage par les requêtes qui lisent une grande quantité de données. Le [uncompressed_cache_size](../server-configuration-parameters/settings.md#server-settings-uncompressed_cache_size) le paramètre serveur définit la taille du cache des blocs non compressés.

-
-Le cache des blocs non compressés stocke les données extraites pour les requêtes. ClickHouse utilise ce cache pour accélérer les réponses aux petites requêtes répétées. Ce paramètre protège le cache contre le saccage par les requêtes qui lisent une grande quantité de données. Le [uncompressed_cache_size](../server-configuration-parameters/settings.md#server-settings-uncompressed_cache_size) le paramètre serveur définit la taille du cache des blocs non compressés.

-Valeur par défaut: 2013265920.
-
-## min_bytes_to_use_direct_io {#settings-min-bytes-to-use-direct-io}
-
-Volume de données minimum requis pour utiliser l'accès direct aux E/S sur le disque de stockage.
-
-ClickHouse utilise ce paramètre lors de la lecture de données à partir de tables. Si le volume total de stockage de toutes les données à lire dépasse `min_bytes_to_use_direct_io` octets, puis ClickHouse lit les données du disque de stockage avec le `O_DIRECT` option.

-## log_queries {#settings-log-queries}
-
-Configuration de la journalisation des requêtes.
-
-Les requêtes envoyées à ClickHouse avec cette configuration sont enregistrées selon les règles du [query_log](../server-configuration-parameters/settings.md#server_configuration_parameters-query-log) paramètre de configuration du serveur.
-
-Exemple:
-
-``` text
-log_queries=1
-```
-
-## log_queries_min_type {#settings-log-queries-min-type}
-
-`query_log` type minimal à enregistrer.
-
-Valeurs possibles:
-- `QUERY_START` (`=1`)
-- `QUERY_FINISH` (`=2`)
-- `EXCEPTION_BEFORE_START` (`=3`)
-- `EXCEPTION_WHILE_PROCESSING` (`=4`)
-
-Valeur par défaut: `QUERY_START`.
-
-Peut être utilisé pour limiter le nombre de entiries va va `query_log`, dites que vous êtes intéressant que dans les erreurs, alors vous pouvez utiliser `EXCEPTION_WHILE_PROCESSING`:
-
-``` text
-log_queries_min_type='EXCEPTION_WHILE_PROCESSING'
-```
-
-## log_query_threads {#settings-log-query-threads}
-
-Configuration de la journalisation des threads de requête.
-
-Les threads de requêtes exécutés par ClickHouse avec cette configuration sont journalisés selon les règles du [query_thread_log](../server-configuration-parameters/settings.md#server_configuration_parameters-query-thread-log) paramètre de configuration du serveur.
-
-Exemple:
-
-``` text
-log_query_threads=1
-```
-
-## max_insert_block_size {#settings-max_insert_block_size}
-
-La taille des blocs à former pour l'insertion dans une table.
-Ce paramètre s'applique uniquement dans les cas où le serveur formes les blocs.
-Par exemple, pour une insertion via L'interface HTTP, le serveur analyse le format de données et forme des blocs de la taille spécifiée.
-Mais lors de l'utilisation de clickhouse-client, le client analyse les données ‘max_insert_block_size’ le réglage sur le serveur n'affecte pas la taille des blocs insérés.
-Le paramètre n'a pas non plus de but lors de L'utilisation D'INSERT SELECT, car les données sont insérées à l'aide des mêmes blocs qui sont formés après SELECT.
-
-Valeur par défaut: 1 048 576 octets.
-
-La valeur par défaut est légèrement supérieure à `max_block_size`. La raison en est que certains moteurs de table (`*MergeTree`) former une partie de données sur le disque pour chaque bloc inséré, qui est une entité assez grande. Pareillement, `*MergeTree` les tables trient les données lors de l'insertion et une taille de bloc suffisamment grande permet de trier plus de données dans la RAM.
-
-## min_insert_block_size_rows {#min-insert-block-size-rows}
-
-Définit le nombre minimum de lignes dans le bloc qui peut être inséré dans un tableau par un `INSERT` requête. Les blocs de plus petite taille sont écrasés en plus gros.
-
-Valeurs possibles:
-
--   Entier positif.
--   0 — Squashing disabled.
-
-Valeur par défaut: 1048576.
-
-## min_insert_block_size_bytes {#min-insert-block-size-bytes}
-
-Définit le nombre minimal d'octets dans le bloc qui peut être inséré dans un tableau par un `INSERT` requête. Les blocs de plus petite taille sont écrasés en plus gros.
-
-Valeurs possibles:
-
--   Entier positif.
--   0 — Squashing disabled.
-
-Valeur par défaut: 268435456.
-
-## max_replica_delay_for_distributed_queries {#settings-max_replica_delay_for_distributed_queries}
-
-Désactive les répliques en retard pour les requêtes distribuées. Voir [Réplication](../../engines/table-engines/mergetree-family/replication.md).
-
-Définit le temps en secondes. Si une réplique accuse plus de retard que la valeur définie, cette réplique n'est pas utilisée.
-
-Valeur par défaut: 300.
-
-Utilisé lors de l'exécution `SELECT` à partir d'une table distribuée qui pointe vers des tables répliquées.
-
-## max_threads {#settings-max_threads}
-
-Nombre maximal de threads de traitement des requêtes, à l'exclusion des threads de récupération de données à partir de serveurs distants (voir ‘max_distributed_connections’ paramètre).
-
-Ce paramètre s'applique aux threads qui effectuent les mêmes étapes du pipeline de traitement des requêtes en parallèle.
-Par exemple, lors de la lecture d'une table, s'il est possible d'évaluer des expressions avec des fonctions, filtrer avec WHERE et pré-agréger pour GROUP BY en parallèle en utilisant au moins ‘max_threads’ nombre de threads, puis ‘max_threads’ sont utilisés.
-
-Valeur par défaut: nombre de cœurs de processeur physiques.
-
-Si moins d'une requête SELECT est normalement exécutée sur un serveur à la fois, définissez ce paramètre sur une valeur légèrement inférieure au nombre réel de cœurs de processeur.
-
-Pour les requêtes qui sont terminées rapidement en raison d'une limite, vous pouvez définir une valeur inférieure ‘max_threads’. Par exemple, si le nombre d'entrées se trouvent dans chaque bloc et max_threads = 8, 8 blocs sont récupérées, même s'il aurait été suffisante pour lire un seul.
-
-Le plus petit de la `max_threads` valeur, moins la mémoire est consommée.
-
-## max_insert_threads {#settings-max-insert-threads}
-
-Nombre maximal de threads à exécuter `INSERT SELECT` requête.
-
-Valeurs possibles:
-
--   0 (or 1) — `INSERT SELECT` pas d'exécution parallèle.
--   Entier positif. Plus grand que 1.
-
-Valeur par défaut: 0.
-
-Parallèle `INSERT SELECT` n'a d'effet que si l' `SELECT` une partie est exécutée en parallèle, voir [max_threads](#settings-max_threads) paramètre.
-Des valeurs plus élevées conduiront à une utilisation de la mémoire plus élevée.
-
-## max_compress_block_size {#max-compress-block-size}
-
-La taille maximale des blocs de données non compressées avant la compression pour l'écriture dans une table. Par défaut, 1 048 576 (1 MiB). Si la taille est réduite, le taux de compression est considérablement réduit, la vitesse de compression et de décompression augmente légèrement en raison de la localisation du cache, et la consommation de mémoire est réduite. Il n'y aucune raison de modifier ce paramètre.
-
-Ne confondez pas les blocs pour la compression (un morceau de mémoire constitué d'octets) avec des blocs pour le traitement des requêtes (Un ensemble de lignes d'une table).

-Pour [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md)" table. Afin de réduire la latence lors du traitement des requêtes, un bloc est compressé lors de l'écriture de la marque suivante si sa taille est au moins ‘min_compress_block_size’. Par défaut, 65 536.
-
-La taille réelle du bloc, si les données non compressées sont inférieures à ‘max_compress_block_size’ pas moins de cette valeur et pas moins que le volume de données pour une marque.
-
-Regardons un exemple. Supposons que ‘index_granularity’ a 8192 lors de la création de la table.
-
-Nous écrivons une colonne de type UInt32 (4 octets par valeur). Lors de l'écriture de 8192 lignes, le total sera de 32 KO de données. Puisque min_compress_block_size = 65 536, un bloc compressé sera formé pour toutes les deux marques.
-
-Nous écrivons une colonne URL avec le type de chaîne (taille moyenne de 60 octets par valeur). Lors de l'écriture de 8192 lignes, la moyenne sera légèrement inférieure à 500 Ko de données. Comme il s'agit de plus de 65 536, un bloc compressé sera formé pour chaque marque. Dans ce cas, lors de la lecture de données du disque dans la plage d'une seule marque, les données supplémentaires ne seront pas décompressées.
-
-Il n'y aucune raison de modifier ce paramètre.
-
-## max_query_size {#settings-max_query_size}
-
-La partie maximale d'une requête qui peut être prise en RAM pour l'analyse avec L'analyseur SQL.
-La requête INSERT contient également des données pour INSERT qui sont traitées par un analyseur de flux séparé (qui consomme O (1) RAM), qui n'est pas inclus dans cette restriction.
-
-Valeur par défaut: 256 Ko.
-
-## interactive_delay {#interactive-delay}
-
-Intervalle en microsecondes pour vérifier si l'exécution de la requête a été annulée et envoyer la progression.
-
-Valeur par défaut: 100 000 (vérifie l'Annulation et envoie la progression dix fois par seconde).
-
-## connect_timeout, receive_timeout, send_timeout {#connect-timeout-receive-timeout-send-timeout}
-
-Délais d'attente en secondes sur le socket utilisé pour communiquer avec le client.
-
-Valeur par défaut: 10, 300, 300.
-
-## cancel_http_readonly_queries_on_client_close {#cancel-http-readonly-queries-on-client-close}
-
-Cancels HTTP read-only queries (e.g. SELECT) when a client closes the connection without waiting for the response.
-
-Valeur par défaut: 0
-
-## poll_interval {#poll-interval}
-
-Verrouillez une boucle d'attente pendant le nombre de secondes spécifié.
-
-Valeur par défaut: 10.
-
-## max_distributed_connections {#max-distributed-connections}
-
-Nombre maximal de connexions simultanées avec des serveurs distants pour le traitement distribué d'une seule requête vers une seule table distribuée. Nous vous recommandons de définir une valeur au moins égale au nombre de serveurs dans le cluster.
-
-Valeur par défaut: 1024.
-
-Les paramètres suivants ne sont utilisés que lors de la création de tables distribuées (et lors du lancement d'un serveur), il n'y a donc aucune raison de les modifier lors de l'exécution.
-
-## distributed_connections_pool_size {#distributed-connections-pool-size}
-
-Nombre maximal de connexions simultanées avec des serveurs distants pour le traitement distribué de toutes les requêtes vers une seule table distribuée. Nous vous recommandons de définir une valeur au moins égale au nombre de serveurs dans le cluster.
-
-Valeur par défaut: 1024.
-
-## connect_timeout_with_failover_ms {#connect-timeout-with-failover-ms}
-
-Délai d'attente en millisecondes pour la connexion à un serveur distant pour un moteur de table distribué, si ‘shard’ et ‘replica’ les sections sont utilisées dans la définition du cluster.
-En cas d'échec, plusieurs tentatives sont faites pour se connecter à diverses répliques.
-
-Valeur par défaut: 50.
-
-## connections_with_failover_max_tries {#connections-with-failover-max-tries}
-
-Nombre maximal de tentatives de connexion avec chaque réplique pour le moteur de table distribué.
-
-Valeur par défaut: 3.
-
-## extrême {#extremes}
-
-Indique s'il faut compter les valeurs extrêmes (les minimums et les maximums dans les colonnes d'un résultat de requête). Accepte 0 ou 1. Par défaut, 0 (désactivé).
-Pour plus d'informations, consultez la section “Extreme values”.
-
-## use_uncompressed_cache {#setting-use_uncompressed_cache}
-
-Indique s'il faut utiliser un cache de blocs non compressés. Accepte 0 ou 1. Par défaut, 0 (désactivé).
-L'utilisation du cache non compressé (uniquement pour les tables de la famille MergeTree) peut réduire considérablement la latence et augmenter le débit lorsque vous travaillez avec un grand nombre de requêtes courtes. Activez ce paramètre pour les utilisateurs qui envoient des requêtes courtes fréquentes. Faites également attention à la [uncompressed_cache_size](../server-configuration-parameters/settings.md#server-settings-uncompressed_cache_size) configuration parameter (only set in the config file) – the size of uncompressed cache blocks. By default, it is 8 GiB. The uncompressed cache is filled in as needed and the least-used data is automatically deleted.
-
-Pour les requêtes qui lisent au moins un volume de données assez important (un million de lignes ou plus), le cache non compressé est désactivé automatiquement pour économiser de l'espace pour les requêtes vraiment petites. Cela signifie que vous pouvez garder la ‘use_uncompressed_cache’ toujours la valeur 1.
-
-## replace_running_query {#replace-running-query}
-
-Lors de l'utilisation de L'interface HTTP, le ‘query_id’ le paramètre peut être passé. C'est n'importe quelle chaîne qui sert d'Identificateur de requête.
-Si une requête d'un utilisateur avec le même ‘query_id’ il existe déjà à ce moment, le comportement dépend de la ‘replace_running_query’ paramètre.
-
-`0` (default) – Throw an exception (don't allow the query to run if a query with the same ‘query_id’ est déjà en cours d'exécution).
-
-`1` – Cancel the old query and start running the new one.
-
-Yandex.Metrica utilise ce paramètre défini sur 1 pour implémenter des suggestions de conditions de segmentation. Après avoir entré le caractère suivant, si l'ancienne requête n'est pas encore terminée, elle doit être annulée.
-
-## stream_flush_interval_ms {#stream-flush-interval-ms}
-
-Fonctionne pour les tables avec des flux dans le cas d'une expiration, ou lorsqu'un thread génère [max_insert_block_size](#settings-max_insert_block_size) rangée.
-
-La valeur par défaut est 7500.
-
-Plus la valeur est petite, plus les données sont vidées dans la table. Régler la valeur trop faible entraîne de mauvaises performances.
-
-## équilibrage {#settings-load_balancing}
-
-Spécifie l'algorithme de sélection des réplicas utilisé pour le traitement des requêtes distribuées.
-
-ClickHouse prend en charge les algorithmes suivants de choix des répliques:
-
--   [Aléatoire](#load_balancing-random) (par défaut)
--   [Nom d'hôte le plus proche](#load_balancing-nearest_hostname)
--   [Afin](#load_balancing-in_order)
--   [Premier ou aléatoire](#load_balancing-first_or_random)
-
-### Aléatoire (par défaut) {#load_balancing-random}
-
-``` sql
-load_balancing = random
-```
-
-Le nombre d'erreurs est compté pour chaque réplique. La requête est envoyée au réplica avec le moins d'erreurs, et s'il y en a plusieurs, à n'importe qui d'entre eux.
-Inconvénients: la proximité du serveur n'est pas prise en compte; si les répliques ont des données différentes, vous obtiendrez également des données différentes.
-
-### Nom D'Hôte Le Plus Proche {#load_balancing-nearest_hostname}
-
-``` sql
-load_balancing = nearest_hostname
-```
-
-The number of errors is counted for each replica. Every 5 minutes, the number of errors is integrally divided by 2. Thus, the number of errors is calculated for a recent time with exponential smoothing. If there is one replica with a minimal number of errors (i.e. errors occurred recently on the other replicas), the query is sent to it. If there are multiple replicas with the same minimal number of errors, the query is sent to the replica with a hostname that is most similar to the server's hostname in the config file (for the number of different characters in identical positions, up to the minimum length of both hostnames).
-
-Par exemple, exemple01-01-1 et example01-01-2.yandex.ru sont différents dans une position, tandis que l'exemple01-01-1 et l'exemple01-02-2 diffèrent dans deux endroits.
-Cette méthode peut sembler primitive, mais elle ne nécessite pas de données externes sur la topologie du réseau, et elle ne compare pas les adresses IP, ce qui serait compliqué pour nos adresses IPv6.
-
-Ainsi, s'il existe des répliques équivalentes, la plus proche par son nom est préférée.
-Nous pouvons également supposer que lors de l'envoi d'une requête au même serveur, en l'absence d'Échecs, une requête distribuée ira également aux mêmes serveurs. Ainsi, même si des données différentes sont placées sur les répliques, la requête retournera principalement les mêmes résultats.
-
-### Afin {#load_balancing-in_order}
-
-``` sql
-load_balancing = in_order
-```
-
-Répliques avec le même nombre d'erreurs sont accessibles dans le même ordre qu'ils sont définis dans la configuration.
-Cette méthode est appropriée lorsque vous savez exactement quelle réplique est préférable.
-
-### Premier ou aléatoire {#load_balancing-first_or_random}
-
-``` sql
-load_balancing = first_or_random
-```
-
-Cet algorithme choisit la première réplique de l'ensemble ou une réplique aléatoire si la première n'est pas disponible. Il est efficace dans les configurations de topologie de réplication croisée, mais inutile dans d'autres configurations.
-
-Le `first_or_random` algorithme résout le problème de la `in_order` algorithme. Avec `in_order`, si une réplique tombe en panne, la suivante obtient une double charge tandis que les répliques restantes gèrent la quantité habituelle de trafic. Lors de l'utilisation de la `first_or_random` algorithme, la charge est répartie uniformément entre les répliques qui sont encore disponibles.
-
-## prefer_localhost_replica {#settings-prefer-localhost-replica}
-
-Active / désactive préférable d'utiliser le réplica localhost lors du traitement des requêtes distribuées.
-
-Valeurs possibles:
-
--   1 — ClickHouse always sends a query to the localhost replica if it exists.
--   0 — ClickHouse uses the balancing strategy specified by the [équilibrage](#settings-load_balancing) paramètre.
-
-Valeur par défaut: 1.
-
-!!! warning "Avertissement"
-    Désactivez ce paramètre si vous utilisez [max_parallel_replicas](#settings-max_parallel_replicas).
-
-## totals_mode {#totals-mode}
-
-Comment calculer les totaux lorsque HAVING est présent, ainsi que lorsque max_rows_to_group_by et group_by_overflow_mode = ‘any’ sont présents.
-Voir la section “WITH TOTALS modifier”.
-
-## totals_auto_threshold {#totals-auto-threshold}
-
-Le seuil de `totals_mode = 'auto'`.
-Voir la section “WITH TOTALS modifier”.
-
-## max_parallel_replicas {#settings-max_parallel_replicas}
-
-Nombre maximal de répliques pour chaque fragment lors de l'exécution d'une requête.
-Par souci de cohérence (pour obtenir différentes parties du même partage de données), Cette option ne fonctionne que lorsque la clé d'échantillonnage est définie.
-Le retard de réplique n'est pas contrôlé.
-
-## compiler {#compile}
-
-Activer la compilation des requêtes. Par défaut, 0 (désactivé).
-
-La compilation n'est utilisée que pour une partie du pipeline de traitement des requêtes: pour la première étape de l'agrégation (GROUP BY).
-Si cette partie du pipeline a été compilée, la requête peut s'exécuter plus rapidement en raison du déploiement de cycles courts et des appels de fonction d'agrégation intégrés. L'amélioration maximale des performances (jusqu'à quatre fois plus rapide dans de rares cas) est observée pour les requêtes avec plusieurs fonctions d'agrégat simples. Typiquement, le gain de performance est insignifiant. Dans de très rares cas, il peut ralentir l'exécution de la requête.
-
-## min_count_to_compile {#min-count-to-compile}
-
-Combien de fois utiliser potentiellement un morceau de code compilé avant d'exécuter la compilation. Par défaut, 3.
-For testing, the value can be set to 0: compilation runs synchronously and the query waits for the end of the compilation process before continuing execution. For all other cases, use values ​​starting with 1. Compilation normally takes about 5-10 seconds.
-Si la valeur est 1 ou plus, la compilation se produit de manière asynchrone dans un thread séparé. Le résultat sera utilisé dès qu'il sera prêt, y compris les requêtes en cours d'exécution.
-
-Le code compilé est requis pour chaque combinaison différente de fonctions d'agrégat utilisées dans la requête et le type de clés dans la clause GROUP BY.
-The results of the compilation are saved in the build directory in the form of .so files. There is no restriction on the number of compilation results since they don't use very much space. Old results will be used after server restarts, except in the case of a server upgrade – in this case, the old results are deleted.
-
-## output_format_json_quote_64bit_integers {#session_settings-output_format_json_quote_64bit_integers}
-
-Si la valeur est true, les entiers apparaissent entre guillemets lors de l'utilisation des formats JSON\* Int64 et UInt64 (pour la compatibilité avec la plupart des implémentations JavaScript); sinon, les entiers sont sortis sans les guillemets.
-
-## format_csv_delimiter {#settings-format_csv_delimiter}
-
-Caractère interprété comme un délimiteur dans les données CSV. Par défaut, le délimiteur est `,`.
-
-## input_format_csv_unquoted_null_literal_as_null {#settings-input_format_csv_unquoted_null_literal_as_null}
-
-Pour le format D'entrée CSV active ou désactive l'analyse des `NULL` comme littéral (synonyme de `\N`).
-
-## output_format_csv_crlf_end_of_line {#settings-output-format-csv-crlf-end-of-line}
-
-Utilisez le séparateur de ligne de style DOS/Windows (CRLF) en CSV au lieu du style Unix (LF).
-
-## output_format_tsv_crlf_end_of_line {#settings-output-format-tsv-crlf-end-of-line}
-
-Utilisez le séparateur de ligne de style DOC/Windows (CRLF) dans TSV au lieu du style Unix (LF).
-
-## insert_quorum {#settings-insert_quorum}
-
-Active les Écritures de quorum.
-
--   Si `insert_quorum < 2`, les Écritures de quorum sont désactivées.
--   Si `insert_quorum >= 2`, les Écritures de quorum sont activées.
-
-Valeur par défaut: 0.
-
-Quorum écrit
-
-`INSERT` ne réussit que lorsque ClickHouse parvient à écrire correctement les données `insert_quorum` des répliques au cours de la `insert_quorum_timeout`. Si, pour une raison quelconque, le nombre de répliques avec succès écrit n'atteint pas le `insert_quorum`, l'écriture est considérée comme ayant échoué et ClickHouse supprimera le bloc inséré de toutes les répliques où les données ont déjà été écrites.
-
-Toutes les répliques du quorum sont cohérentes, c'est-à-dire qu'elles contiennent des données de toutes les `INSERT` requête. Le `INSERT` la séquence est linéarisé.
-
-Lors de la lecture des données écrites à partir du `insert_quorum`, vous pouvez utiliser le [select_sequential_consistency](#settings-select_sequential_consistency) option.
-
-Clickhouse génère une exception
-
--   Si le nombre de répliques au moment de la requête est inférieure à la `insert_quorum`.
--   Lors d'une tentative d'écriture de données lorsque le bloc précédent n'a pas encore été inséré dans le `insert_quorum` des répliques. Cette situation peut se produire si l'utilisateur tente d'effectuer une `INSERT` avant le précédent avec le `insert_quorum` est terminé.

-## insert_quorum_timeout {#settings-insert_quorum_timeout}
-
-Ecrire dans quorum timeout en secondes. Si le délai d'attente est passé et qu'aucune écriture n'a encore eu lieu, ClickHouse génère une exception et le client doit répéter la requête pour écrire le même bloc dans le même réplica ou tout autre réplica.
-
-Valeur par défaut: 60 secondes.

-
-## select_sequential_consistency {#settings-select_sequential_consistency}
-
-Active ou désactive la cohérence séquentielle pour `SELECT` requête:
-
-Valeurs possibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valeur par défaut: 0.
-
-Utilisation
-
-Lorsque la cohérence séquentielle est activée, ClickHouse permet au client d'exécuter `SELECT` requête uniquement pour les répliques qui contiennent des données de toutes les `INSERT` requêtes exécutées avec `insert_quorum`. Si le client fait référence à une réplique partielle, ClickHouse génère une exception. La requête SELECT n'inclut pas les données qui n'ont pas encore été écrites dans le quorum des répliques.

-## insert_deduplicate {#settings-insert-deduplicate}
-
-Active ou désactive la déduplication des blocs `INSERT` (Répliqués\* les tableaux).
-
-Valeurs possibles:
-
--   0 — Disabled.
--   1 — Enabled.
-
-Valeur par défaut: 1.
-
-Par défaut, les blocs insérés dans les tables répliquées `INSERT` déclaration sont dédupliquées (voir [Réplication Des Données](../../engines/table-engines/mergetree-family/replication.md)).
-
-## déduplicate_blocks_in_dependent_materialized_views {#settings-deduplicate-blocks-in-dependent-materialized-views}
-
-Active ou désactive la vérification de déduplication des vues matérialisées qui reçoivent des données à partir de tables\* répliquées.
-
-Valeurs possibles:
-
-      0 — Disabled.
-      1 — Enabled.
-
-Valeur par défaut: 0.
-
-Utilisation
-
-Par défaut, la déduplication n'est pas effectuée pour les vues matérialisées mais en amont, dans la table source.
-Si un bloc inséré est ignoré en raison de la déduplication dans la table source, il n'y aura pas d'insertion dans les vues matérialisées attachées. Ce comportement existe pour permettre l'insertion de données hautement agrégées dans des vues matérialisées, dans les cas où les blocs insérés sont les mêmes après l'agrégation de vues matérialisées mais dérivés de différentes insertions dans la table source.
-Dans le même temps, ce comportement “breaks” `INSERT` idempotence. Si un `INSERT` dans la table principale a été un succès et `INSERT` into a materialized view failed (e.g. because of communication failure with Zookeeper) a client will get an error and can retry the operation. However, the materialized view won't receive the second insert because it will be discarded by deduplication in the main (source) table. The setting `deduplicate_blocks_in_dependent_materialized_views` permet de changer ce comportement. Lors d'une nouvelle tentative, une vue matérialisée recevra l'insertion répétée et effectuera une vérification de déduplication par elle-même,
-ignorant le résultat de la vérification pour la table source, et insérera des lignes perdues en raison de la première défaillance.

-!!! warning "Avertissement"
-    Pour utiliser ce paramètre, vous devez définir l' `CAP_SYS_NICE` capacité. Le `clickhouse-server` paquet configure lors de l'installation. Certains environnements virtuels ne vous permettent pas de définir `CAP_SYS_NICE` capacité. Dans ce cas, `clickhouse-server` affiche un message à ce sujet au début.
-
-Valeurs possibles:
-
--   Vous pouvez définir des valeurs dans la gamme `[-20, 19]`.
-
-Des valeurs plus faibles signifient une priorité plus élevée. Les discussions avec des bas `nice` les valeurs de priorité sont effectués plus fréquemment que les discussions avec des valeurs élevées. Les valeurs élevées sont préférables pour les requêtes non interactives de longue durée, car elles leur permettent d'abandonner rapidement des ressources au profit de requêtes interactives courtes lorsqu'elles arrivent.

-# Les Tables Système {#system-tables}
-
-Les tables système sont utilisées pour implémenter une partie des fonctionnalités du système et pour fournir un accès à des informations sur le fonctionnement du système.
-Vous ne pouvez pas supprimer une table système (mais vous pouvez effectuer un détachement).
-Les tables système n'ont pas de fichiers avec des données sur le disque ou de fichiers avec des métadonnées. Le serveur crée toutes les tables système au démarrage.
-Les tables système sont en lecture seule.
-Ils sont situés dans la ‘system’ la base de données.
-
-## système.asynchronous_metrics {#system_tables-asynchronous_metrics}
-
-Contient des mesures qui sont calculées périodiquement en arrière-plan. Par exemple, la quantité de RAM utilisée.
-
-Colonne:
-
--   `metric` ([Chaîne](../sql-reference/data-types/string.md)) — Metric name.
--   `value` ([Float64](../sql-reference/data-types/float.md)) — Metric value.
-
-**Exemple**
-
-``` sql
-SELECT * FROM system.asynchronous_metrics LIMIT 10
-```

-
-Veuillez noter que `errors_count` est mise à jour une fois par requête à la grappe, mais `estimated_recovery_time` est recalculé sur-demande. Il pourrait donc y avoir un cas de non-zéro `errors_count` et zéro `estimated_recovery_time`, cette requête suivante sera nulle `errors_count` et essayez d'utiliser des répliques comme si elle ne comporte pas d'erreurs.

-
-Chaque requête crée une ou deux lignes dans le `query_log` le tableau, en fonction de l'état de la requête:
-
-1.  Si l'exécution de la requête est réussie, deux événements de type 1 et 2 sont créés (voir `type` colonne).
-2.  Si une erreur s'est produite pendant le traitement de la requête, deux événements avec les types 1 et 4 sont créés.
-3.  Si une erreur s'est produite avant le lancement de la requête, un seul événement de type 3 est créé.
-
-Par défaut, les journaux sont ajoutés à la table à des intervalles de 7,5 secondes. Vous pouvez définir cet intervalle dans la [query_log](server-configuration-parameters/settings.md#server_configuration_parameters-query-log) configuration du serveur (voir `flush_interval_milliseconds` paramètre). Pour vider les journaux de force du tampon mémoire dans la table, utilisez le `SYSTEM FLUSH LOGS` requête.

-
--   `database` (`String`) - Nom de base de données
--   `table` (`String`)- Nom de la Table
--   `engine` (`String`)- Nom du moteur de Table
--   `is_leader` (`UInt8`) - Si la réplique est le chef de file.
-    Une seule réplique à la fois peut être le leader. Le leader est responsable de la sélection des fusions d'arrière-plan à effectuer.
-    Notez que les Écritures peuvent être effectuées sur n'importe quel réplica disponible et ayant une session dans ZK, qu'il s'agisse d'un leader.
--   `can_become_leader` (`UInt8`)- Si la réplique peut être élue en tant que leader.
--   `is_readonly` (`UInt8`) - Si la réplique est en mode lecture seule.
-    Ce mode est activé si la configuration n'a pas de sections avec ZooKeeper, si une erreur inconnue s'est produite lors de la réinitialisation des sessions dans ZooKeeper et lors de la réinitialisation des sessions dans ZooKeeper.
--   `is_session_expired` (`UInt8`)- la session avec ZooKeeper a expiré. Fondamentalement le même que `is_readonly`.
--   `future_parts` (`UInt32`)- Le nombre de parties de données qui apparaîtront à la suite D'insertions ou de fusions qui n'ont pas encore été effectuées.
--   `parts_to_check` (`UInt32`) - Le nombre de parties des données dans la file d'attente pour la vérification. Une pièce est placée dans la file d'attente de vérification s'il y a un soupçon qu'elle pourrait être endommagée.
--   `zookeeper_path` (`String`)- Chemin d'accès aux données de la table dans ZooKeeper.
--   `replica_name` (`String`) - Réplique nom de la Gardienne. Différentes répliques d'une même table ont des noms différents.
--   `replica_path` (`String`)- Chemin vers les données de réplique dans ZooKeeper. La même chose que la concaténation ‘zookeeper_path/replicas/replica_path’.
--   `columns_version` (`Int32`)- Numéro de Version de la structure de la table. Indique combien de fois ALTER a été effectué. Si les répliques ont des versions différentes, cela signifie que certaines répliques n'ont pas encore Toutes les modifications.
--   `queue_size` (`UInt32`),- La taille de la file d'attente pour les opérations en attente d'être exécuté. Les opérations comprennent l'insertion de blocs de données, les fusions et certaines autres actions. Il coïncide généralement avec `future_parts`.
--   `inserts_in_queue` (`UInt32`) - Nombre d'insertions de blocs de données qui doivent être faits. Les Insertions sont généralement répliquées assez rapidement. Si ce nombre est grand, cela signifie que quelque chose est faux.
--   `merges_in_queue` (`UInt32`) - Le nombre de fusions en attente d'être fait. Parfois, les fusions sont longues, donc cette valeur peut être supérieure à zéro pendant une longue période.
--   `part_mutations_in_queue` (`UInt32`) - Le nombre de mutations en attente d'être fait.
--   `queue_oldest_time` (`DateTime`) - Si `queue_size` supérieur à 0, indique quand l'opération la plus ancienne a été ajoutée à la file d'attente.
--   `inserts_oldest_time` (`DateTime`) - Voir `queue_oldest_time`
--   `merges_oldest_time` (`DateTime`) - Voir `queue_oldest_time`
--   `part_mutations_oldest_time` (`DateTime`) - Voir `queue_oldest_time`
-
-Les 4 colonnes suivantes ont une valeur non nulle uniquement lorsqu'il y a une session active avec ZK.
-
--   `log_max_index` (`UInt64`) - Maximum nombre d'entrées dans le journal de l'activité générale.
--   `log_pointer` (`UInt64`)- Numéro d'entrée Maximum dans le journal de l'activité générale que le réplica a copié dans sa file d'attente d'exécution, plus un. Si `log_pointer` est beaucoup plus petite que `log_max_index` quelque chose ne va pas.
--   `last_queue_update` (`DateTime`) - Lorsque la file d'attente a été mise à jour la dernière fois.
--   `absolute_delay` (`UInt64`)- Combien de décalage en secondes la réplique actuelle A.
--   `total_replicas` (`UInt8`) - Le nombre total de répliques connues de ce tableau.
--   `active_replicas` (`UInt8`) - Le nombre de répliques de cette table qui ont une session dans ZooKeeper (c'est-à-dire le nombre de répliques fonctionnelles).
-
-Si vous demandez toutes les colonnes, la table peut fonctionner un peu lentement, car plusieurs lectures de ZooKeeper sont faites pour chaque ligne.
-Si vous ne demandez pas les 4 dernières colonnes (log_max_index, log_pointer, total_replicas, active_replicas), la table fonctionne rapidement.
-
-Par exemple, vous pouvez vérifier que tout fonctionne correctement comme ceci:
-
-``` sql
-SELECT
-    database,
-    table,
-    is_leader,
-    is_readonly,
-    is_session_expired,
-    future_parts,

-    columns_version,
-    queue_size,
-    inserts_in_queue,
-    merges_in_queue,
-    log_max_index,
-    log_pointer,
-    total_replicas,
-    active_replicas
-FROM system.replicas

-## système.mutation {#system_tables-mutations}
-
-Le tableau contient des informations sur [mutation](../sql-reference/statements/alter.md#alter-mutations) des tables MergeTree et leur progression. Chaque commande de mutation est représentée par une seule ligne. Le tableau comporte les colonnes suivantes:
-
-**base de données**, **table** - Le nom de la base de données et de la table à laquelle la mutation a été appliquée.
-
-**mutation_id** - Le numéro d'identification de la mutation. Pour les tables répliquées ces ID correspondent aux noms znode dans le `<table_path_in_zookeeper>/mutations/` répertoire de la Gardienne. Pour les tables non compliquées, Les Id correspondent aux noms de fichiers dans le répertoire de données de la table.
-
-**commande** - La chaîne de commande mutation (la partie de la requête après `ALTER TABLE [db.]table`).
-
-**create_time** - Quand cette commande de mutation a été soumise pour exécution.
-
-**block_numbers.partition_id**, **block_numbers.nombre** - Une colonne imbriquée. Pour les mutations de tables répliquées, il contient un enregistrement pour chaque partition: l'ID de partition et le numéro de bloc acquis par la mutation (dans chaque partition, seules les parties contenant des blocs avec des nombres inférieurs au numéro de bloc acquis par la mutation dans cette partition seront mutées). Dans les tables non répliquées, les numéros de bloc de toutes les partitions forment une seule séquence. Cela signifie que pour les mutations de tables non répliquées, la colonne contiendra un enregistrement avec un seul numéro de bloc acquis par la mutation.
-
-**parts_to_do** - Le nombre de parties de données qui doivent être mutées pour que la mutation se termine.
-
-**_done** - La mutation est faite? Notez que même si `parts_to_do = 0` il est possible qu'une mutation d'une table répliquée ne soit pas encore effectuée en raison d'un INSERT de longue durée qui créera une nouvelle partie de données qui devra être mutée.
-
-S'il y avait des problèmes avec la mutation de certaines parties, les colonnes suivantes contiennent des informations supplémentaires:
-
-**latest_failed_part** - Le nom de la partie la plus récente qui n'a pas pu être mutée.
-
-**latest_fail_time** - Le temps de la partie la plus récente mutation de l'échec.
-
-**latest_fail_reason** - Le message d'exception qui a provoqué l'échec de la mutation de pièce la plus récente.

-## système.storage_policies {#system_tables-storage_policies}
-
-Contient des informations sur les stratégies de stockage et les volumes définis [configuration du serveur](../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes_configure).
-
-Colonne:
-
--   `policy_name` ([Chaîne](../sql-reference/data-types/string.md)) — Name of the storage policy.

----
-
-# Recommandations D'Utilisation {#usage-recommendations}
-
-## Gouverneur de mise à L'échelle du processeur {#cpu-scaling-governor}
-
-Utilisez toujours la `performance` mise à l'échelle gouverneur. Le `on-demand` gouverneur de mise à l'échelle fonctionne bien pire avec une demande constamment élevée.
-
-``` bash
-$ echo 'performance' | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
-```
-
-## CPU Limitations {#cpu-limitations}
-
-Les processeurs peuvent surchauffer. Utiliser `dmesg` pour voir si la fréquence D'horloge du processeur était limitée en raison de la surchauffe.
-La restriction peut également être définie en externe au niveau du centre de données. Vous pouvez utiliser `turbostat` à surveiller sous une charge.
-
-## RAM {#ram}
-
-Pour de petites quantités de données (jusqu'à ~200 GO en mode compressé), il est préférable d'utiliser autant de mémoire que le volume de données.
-Pour de grandes quantités de données et lors du traitement de requêtes interactives (en ligne), vous devez utiliser une quantité raisonnable de RAM (128 Go ou plus) afin que le sous-ensemble de données chaudes s'intègre dans le cache des pages.
-Même pour des volumes de données d'environ 50 To par serveur, l'utilisation de 128 Go de RAM améliore considérablement les performances des requêtes par rapport à 64 Go.
-
-Ne désactivez pas de surcharge. Valeur `cat /proc/sys/vm/overcommit_memory` devrait être 0 ou 1. Exécuter
-
-``` bash
-$ echo 0 | sudo tee /proc/sys/vm/overcommit_memory
-```
-
-## Huge Pages {#huge-pages}
-
-Toujours désactiver les pages énormes transparentes. Il interfère avec les allocateurs de mémoire, ce qui entraîne une dégradation significative des performances.
-
-``` bash
-$ echo 'never' | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
-```
-
-Utiliser `perf top` pour regarder le temps passé dans le noyau pour la gestion de la mémoire.
-Les pages énormes permanentes n'ont pas non plus besoin d'être allouées.
-
-## Sous-Système De Stockage {#storage-subsystem}
-
-Si votre budget vous permet D'utiliser SSD, utilisez SSD.
-Sinon, utilisez un disque dur. Disques durs SATA 7200 RPM fera l'affaire.
-
-Donner la préférence à un grand nombre de serveurs avec des disques durs locaux sur un plus petit nombre de serveurs avec un disque attaché étagères.
-Mais pour stocker des archives avec des requêtes rares, les étagères fonctionneront.
-
-## RAID {#raid}
-
-Lorsque vous utilisez le disque dur, vous pouvez combiner leur RAID-10, RAID-5, RAID-6 ou RAID-50.
-Pour Linux, le RAID logiciel est meilleur (avec `mdadm`). Nous ne recommandons pas d'utiliser LVM.
-Lors de la création de RAID-10, sélectionnez `far` disposition.
-Si votre budget le permet, choisissez RAID-10.
-
-Si vous avez plus de 4 disques, Utilisez RAID-6 (préféré) ou RAID-50, au lieu de RAID-5.
-Lorsque vous utilisez RAID-5, RAID-6 ou RAID-50, augmentez toujours stripe_cache_size, car la valeur par défaut n'est généralement pas le meilleur choix.
-
-``` bash
-$ echo 4096 | sudo tee /sys/block/md2/md/stripe_cache_size
-```
-
-Calculez le nombre exact à partir du nombre de périphériques et de la taille du bloc, en utilisant la formule: `2 * num_devices * chunk_size_in_bytes / 4096`.
-
-Une taille de bloc de 1024 KO est suffisante pour toutes les configurations RAID.
-Ne définissez jamais la taille du bloc trop petite ou trop grande.
-
-Vous pouvez utiliser RAID-0 sur SSD.
-Quelle que soit L'utilisation du RAID, utilisez toujours la réplication pour la sécurité des données.
-
-Activer NCQ avec une longue file d'attente. Pour HDD, choisissez le planificateur CFQ, et pour SSD, choisissez noop. Ne pas réduire le ‘readahead’ paramètre.
-Pour le disque dur, activez le cache d'écriture.
-
-## Système De Fichiers {#file-system}
-
-Ext4 est l'option la plus fiable. Définir les options de montage `noatime, nobarrier`.
-XFS est également adapté, mais il n'a pas été aussi soigneusement testé avec ClickHouse.
-La plupart des autres systèmes de fichiers devraient également fonctionner correctement. Les systèmes de fichiers avec allocation retardée fonctionnent mieux.
-
-## Le Noyau Linux {#linux-kernel}
-
-N'utilisez pas un noyau Linux obsolète.
-
-## Réseau {#network}
-
-Si vous utilisez IPv6, augmenter la taille du cache.
-Le noyau Linux avant 3.2 avait une multitude de problèmes avec l'implémentation D'IPv6.
-
-Utilisez au moins un réseau de 10 Go, si possible. 1 Go fonctionnera également, mais ce sera bien pire pour patcher des répliques avec des dizaines de téraoctets de données, ou pour traiter des requêtes distribuées avec une grande quantité de données intermédiaires.
-
-## ZooKeeper {#zookeeper}
-
-Vous utilisez probablement déjà ZooKeeper à d'autres fins. Vous pouvez utiliser la même installation de ZooKeeper, si elle n'est pas déjà surchargée.
-
-It's best to use a fresh version of ZooKeeper – 3.4.9 or later. The version in stable Linux distributions may be outdated.
-
-Vous ne devez jamais utiliser de scripts écrits manuellement pour transférer des données entre différents clusters ZooKeeper, car le résultat sera incorrect pour les nœuds séquentiels. Ne jamais utiliser de l' “zkcopy” utilitaire pour la même raison: https://github.com/ksprojects/zkcopy/issues/15
-
-Si vous souhaitez diviser un cluster Zookeeper existant en deux, le bon moyen est d'augmenter le nombre de ses répliques, puis de le reconfigurer en deux clusters indépendants.
-
-N'exécutez pas ZooKeeper sur les mêmes serveurs que ClickHouse. Parce que ZooKeeper est très sensible à la latence et ClickHouse peut utiliser toutes les ressources système disponibles.
-
-Avec les paramètres par défaut, ZooKeeper est une bombe à retardement:
-
-> Le serveur ZooKeeper ne supprime pas les fichiers des anciens snapshots et journaux lors de l'utilisation de la configuration par défaut (voir autopurge), et c'est la responsabilité de l'opérateur.
-
-Cette bombe doit être désamorcée.
-
-La configuration ZooKeeper (3.5.1) ci-dessous est utilisée dans le Yandex.Environnement de production Metrica au 20 mai 2017:
-
-zoo.cfg:
-

-
-# To avoid seeks ZooKeeper allocates space in the transaction log file in
-# blocks of preAllocSize kilobytes. The default block size is 64M. One reason
-# for changing the size of the blocks is to reduce the block size if snapshots
-# are taken more often. (Also, see snapCount).
-preAllocSize=131072
-
-# Clients can submit requests faster than ZooKeeper can process them,
-# especially if there are a lot of clients. To prevent ZooKeeper from running
-# out of memory due to queued requests, ZooKeeper will throttle clients so that
-# there is no more than globalOutstandingLimit outstanding requests in the
-# system. The default limit is 1,000.ZooKeeper logs transactions to a
-# transaction log. After snapCount transactions are written to a log file a
-# snapshot is started and a new transaction log file is started. The default
-# snapCount is 10,000.

-
-## Installation {#troubleshooting-installation-errors}
-
-### Vous ne pouvez pas obtenir de paquets deb à partir du référentiel ClickHouse avec Apt-get {#you-cannot-get-deb-packages-from-clickhouse-repository-with-apt-get}
-
--   Vérifiez les paramètres du pare-feu.
--   Si vous ne pouvez pas accéder au référentiel pour quelque raison que ce soit, téléchargez les packages comme décrit dans [Prise en main](../getting-started/index.md) article et les installer manuellement en utilisant le `sudo dpkg -i <packages>` commande. Vous aurez aussi besoin d' `tzdata` paquet.
-
-## Connexion au Serveur {#troubleshooting-accepts-no-connections}
-
-Problèmes possibles:
-
--   Le serveur n'est pas en cours d'exécution.
--   Paramètres de configuration inattendus ou incorrects.
-
-### Le Serveur N'Est Pas En Cours D'Exécution {#server-is-not-running}
-
-**Vérifiez si le serveur est runnnig**
-
-Commande:
-
-``` bash
-$ sudo service clickhouse-server status
-```
-
-Si le serveur n'est pas en cours d'exécution, démarrez-le avec la commande:
-
-``` bash
-$ sudo service clickhouse-server start
-```
-
-**Vérifier les journaux**
-
-Le journal principal de `clickhouse-server` est dans `/var/log/clickhouse-server/clickhouse-server.log` par défaut.
-
-Si le serveur a démarré avec succès, vous devriez voir les chaînes:
-
--   `<Information> Application: starting up.` — Server started.
--   `<Information> Application: Ready for connections.` — Server is running and ready for connections.
-
-Si `clickhouse-server` démarrage a échoué avec une erreur de configuration, vous devriez voir la `<Error>` chaîne avec une description de l'erreur. Exemple:
-
-``` text
-2019.01.11 15:23:25.549505 [ 45 ] {} <Error> ExternalDictionaries: Failed reloading 'event2id' external dictionary: Poco::Exception. Code: 1000, e.code() = 111, e.displayText() = Connection refused, e.what() = Connection refused
-```
-
-Si vous ne voyez pas d'erreur à la fin du fichier, parcourez le fichier entier à partir de la chaîne:
-
-``` text
-<Information> Application: starting up.
-```
-
-Si vous essayez de démarrer une deuxième instance de `clickhouse-server` sur le serveur, vous voyez le journal suivant:
-
-``` text
-2019.01.11 15:25:11.151730 [ 1 ] {} <Information> : Starting ClickHouse 19.1.0 with revision 54413
-2019.01.11 15:25:11.154578 [ 1 ] {} <Information> Application: starting up

-2019.01.11 15:25:11.156716 [ 2 ] {} <Information> BaseDaemon: Stop SignalListener thread
-```
-
-**Voir système.d les journaux**
-
-Si vous ne trouvez aucune information utile dans `clickhouse-server` journaux ou il n'y a pas de journaux, vous pouvez afficher `system.d` journaux à l'aide de la commande:
-
-``` bash
-$ sudo journalctl -u clickhouse-server
-```
-
-**Démarrer clickhouse-server en mode interactif**
-
-``` bash
-$ sudo -u clickhouse /usr/bin/clickhouse-server --config-file /etc/clickhouse-server/config.xml
-```
-
-Cette commande démarre le serveur en tant qu'application interactive avec les paramètres standard du script de démarrage automatique. Dans ce mode `clickhouse-server` imprime tous les messages d'événement dans la console.
-
-### Paramètres De Configuration {#configuration-parameters}
-
-Vérifier:
-
--   Le panneau paramètres.
-
-    Si vous exécutez ClickHouse dans Docker dans un réseau IPv6, assurez-vous que `network=host` est définie.
-
--   Paramètres du point de terminaison.
-
-    Vérifier [listen_host](server-configuration-parameters/settings.md#server_configuration_parameters-listen_host) et [tcp_port](server-configuration-parameters/settings.md#server_configuration_parameters-tcp_port) paramètre.
-
-    Clickhouse server accepte les connexions localhost uniquement par défaut.
-
--   Paramètres du protocole HTTP.
-
-    Vérifiez les paramètres de protocole pour L'API HTTP.
-
--   Paramètres de connexion sécurisés.
-
-    Vérifier:
-
-    -   Le [tcp_port_secure](server-configuration-parameters/settings.md#server_configuration_parameters-tcp_port_secure) paramètre.
-    -   Paramètres pour [SSL sertificates](server-configuration-parameters/settings.md#server_configuration_parameters-openssl).
-
-    Utilisez les paramètres appropriés lors de la connexion. Par exemple, l'utilisation de la `port_secure` paramètre avec `clickhouse_client`.
-
--   Les paramètres de l'utilisateur.
-
-    Vous utilisez peut-être un mauvais nom d'utilisateur ou mot de passe.
-
-## Traitement Des Requêtes {#troubleshooting-does-not-process-queries}
-
-Si ClickHouse ne peut pas traiter la requête, il envoie une description d'erreur au client. Dans le `clickhouse-client` vous obtenez une description de l'erreur dans la console. Si vous utilisez L'interface HTTP, ClickHouse envoie la description de l'erreur dans le corps de la réponse. Exemple:
-
-``` bash
-$ curl 'http://localhost:8123/' --data-binary "SELECT a"
-Code: 47, e.displayText() = DB::Exception: Unknown identifier: a. Note that there are no tables (FROM clause) in your query, context: required_names: 'a' source_tables: table_aliases: private_aliases: column_aliases: public_columns: 'a' masked_columns: array_join_columns: source_columns: , e.what() = DB::Exception
-```
-
-Si vous commencez à `clickhouse-client` avec l' `stack-trace` paramètre, ClickHouse renvoie la trace de la pile du serveur avec la description d'une erreur.
-
-Vous pouvez voir un message sur une connexion rompue. Dans ce cas, vous pouvez répéter la requête. Si la connexion se rompt chaque fois que vous effectuez la requête, vérifiez les journaux du serveur pour détecter les erreurs.
-
-## Efficacité du traitement des requêtes {#troubleshooting-too-slow}
-
-Si vous voyez que ClickHouse fonctionne trop lentement, vous devez profiler la charge sur les ressources du serveur et le réseau pour vos requêtes.
-
-Vous pouvez utiliser l'utilitaire clickhouse-benchmark pour profiler les requêtes. Il indique le nombre de requêtes traitées par seconde, le nombre de lignes traitées par seconde, et les percentiles de temps de traitement des requêtes.

-# Mise À Jour De ClickHouse {#clickhouse-update}
-
-Si ClickHouse a été installé à partir de paquets deb, exécutez les commandes suivantes sur le serveur:
-
-``` bash
-$ sudo apt-get update
-$ sudo apt-get install clickhouse-client clickhouse-server
-$ sudo service clickhouse-server restart
-```
-
-Si vous avez installé ClickHouse en utilisant autre chose que les paquets deb recommandés, utilisez la méthode de mise à jour appropriée.
-
-ClickHouse ne prend pas en charge une mise à jour distribuée. L'opération doit être effectuée consécutivement sur chaque serveur séparé. Ne pas mettre à jour tous les serveurs d'un cluster simultanément, ou le cluster sera indisponible pendant un certain temps.

-# clickhouse-benchmark {#clickhouse-benchmark}
-
-Se connecte à un serveur ClickHouse et envoie à plusieurs reprises des requêtes spécifiées.
-
-Syntaxe:
-
-``` bash
-$ echo "single query" | clickhouse-benchmark [keys]
-```
-
-ou
-
-``` bash
-$ clickhouse-benchmark [keys] <<< "single query"
-```
-
-Si vous souhaitez envoyer un ensemble de requêtes, créez un fichier texte et placez chaque requête sur la chaîne individuelle de ce fichier. Exemple:
-
-``` sql
-SELECT * FROM system.numbers LIMIT 10000000
-SELECT 1
-```
-
-Ensuite, passez ce fichier à une entrée standard de `clickhouse-benchmark`.
-
-``` bash
-clickhouse-benchmark [keys] < queries_file
-```
-
-## Touches {#clickhouse-benchmark-keys}
-
--   `-c N`, `--concurrency=N` — Number of queries that `clickhouse-benchmark` envoie simultanément. Valeur par défaut: 1.
--   `-d N`, `--delay=N` — Interval in seconds between intermediate reports (set 0 to disable reports). Default value: 1.
--   `-h WORD`, `--host=WORD` — Server host. Default value: `localhost`. Pour l' [mode de comparaison](#clickhouse-benchmark-comparison-mode) vous pouvez utiliser plusieurs `-h` touches.
--   `-p N`, `--port=N` — Server port. Default value: 9000. For the [mode de comparaison](#clickhouse-benchmark-comparison-mode) vous pouvez utiliser plusieurs `-p` touches.
--   `-i N`, `--iterations=N` — Total number of queries. Default value: 0.
--   `-r`, `--randomize` — Random order of queries execution if there is more then one input query.
--   `-s`, `--secure` — Using TLS connection.
--   `-t N`, `--timelimit=N` — Time limit in seconds. `clickhouse-benchmark` arrête d'envoyer des requêtes lorsque le délai spécifié est atteint. Valeur par défaut: 0 (limite de temps désactivée).
--   `--confidence=N` — Level of confidence for T-test. Possible values: 0 (80%), 1 (90%), 2 (95%), 3 (98%), 4 (99%), 5 (99.5%). Default value: 5. In the [mode de comparaison](#clickhouse-benchmark-comparison-mode) `clickhouse-benchmark` effectue les [Test T de L'étudiant indépendant à deux échantillons](https://en.wikipedia.org/wiki/Student%27s_t-test#Independent_two-sample_t-test) tester pour déterminer si les deux distributions ne sont pas différentes avec le niveau de confiance sélectionné.
--   `--cumulative` — Printing cumulative data instead of data per interval.
--   `--database=DATABASE_NAME` — ClickHouse database name. Default value: `default`.
--   `--json=FILEPATH` — JSON output. When the key is set, `clickhouse-benchmark` génère un rapport dans le fichier JSON spécifié.
--   `--user=USERNAME` — ClickHouse user name. Default value: `default`.
--   `--password=PSWD` — ClickHouse user password. Default value: empty string.
--   `--stacktrace` — Stack traces output. When the key is set, `clickhouse-bencmark` affiche les traces d'exceptions de la pile.
--   `--stage=WORD` — Query processing stage at server. ClickHouse stops query processing and returns answer to `clickhouse-benchmark` à l'étape spécifiée. Valeurs possibles: `complete`, `fetch_columns`, `with_mergeable_state`. Valeur par défaut: `complete`.
--   `--help` — Shows the help message.
-
-Si vous voulez appliquer des [paramètre](../../operations/settings/index.md) pour les requêtes, les passer comme une clé `--<session setting name>= SETTING_VALUE`. Exemple, `--max_memory_usage=1048576`.
-
-## Sortie {#clickhouse-benchmark-output}
-
-Par défaut, `clickhouse-benchmark` les rapports de chaque `--delay` intervalle.

-## Mode De Comparaison {#clickhouse-benchmark-comparison-mode}
-
-`clickhouse-benchmark` peut comparer les performances pour deux serveurs clickhouse en cours d'exécution.
-
-Pour utiliser le mode de comparaison, spécifiez les points de terminaison des deux serveurs par deux paires de `--host`, `--port` touches. Clés appariées ensemble par position dans la liste des arguments, la première `--host` est assorti avec le premier `--port` et ainsi de suite. `clickhouse-benchmark` établit les connexions aux serveurs, puis envoie des requêtes. Chaque requête adressée à un serveur sélectionné au hasard. Les résultats sont présentés pour chaque serveur séparément.

-# clickhouse-copieur {#clickhouse-copier}
-
-Copie les données des tables d'un cluster vers des tables d'un autre cluster (ou du même cluster).
-
-Vous pouvez exécuter plusieurs `clickhouse-copier` instances sur différents serveurs pour effectuer le même travail. ZooKeeper est utilisé pour synchroniser les processus.
-
-Après le démarrage de, `clickhouse-copier`:
-
--   Se connecte à ZooKeeper et reçoit:
-
-    -   La copie de tâches.
-    -   L'état de la copie d'emplois.
-
--   Il effectue les travaux.
-
-    Chaque processus en cours choisit le “closest” eclat du cluster source et copie les données dans le cluster de destination, la refragmentation les données si nécessaire.
-
-`clickhouse-copier` suit les changements dans ZooKeeper et les applique à la volée.
-
-Pour réduire le trafic réseau, nous vous recommandons de `clickhouse-copier` sur le même serveur où se trouvent les données source.
-
-## Course Clickhouse-copieur {#running-clickhouse-copier}
-
-L'utilitaire doit être exécuté manuellement:
-
-``` bash
-$ clickhouse-copier copier --daemon --config zookeeper.xml --task-path /task/path --base-dir /path/to/dir
-```
-
-Paramètre:
-
--   `daemon` — Starts `clickhouse-copier` en mode démon.
--   `config` — The path to the `zookeeper.xml` fichier avec les paramètres pour la connexion à la Gardienne.
--   `task-path` — The path to the ZooKeeper node. This node is used for syncing `clickhouse-copier` processus et stockage des tâches. Les tâches sont stockées dans `$task-path/description`.
--   `task-file` — Optional path to file with task configuration for initial upload to ZooKeeper.
--   `task-upload-force` — Force upload `task-file` même si le nœud existe déjà.
--   `base-dir` — The path to logs and auxiliary files. When it starts, `clickhouse-copier` crée `clickhouse-copier_YYYYMMHHSS_<PID>` les sous-répertoires `$base-dir`. Si ce paramètre est omis, les répertoires sont créés dans le répertoire où `clickhouse-copier` a été lancé.
-
-## Format de Zookeeper.XML {#format-of-zookeeper-xml}

-# clickhouse-local {#clickhouse-local}
-
-Le `clickhouse-local` programme vous permet d'effectuer un traitement rapide sur les fichiers locaux, sans avoir à déployer et configurer le serveur ClickHouse.
-
-Accepte les données qui représentent des tables et les interroge en utilisant [Clickhouse dialecte SQL](../../sql-reference/index.md).
-
-`clickhouse-local` utilise le même noyau que clickhouse server, de sorte qu'il prend en charge la plupart des fonctionnalités et le même ensemble de formats et de moteurs de table.
-
-Par défaut `clickhouse-local` n'a pas accès aux données sur le même hôte, mais il prend en charge le chargement de la configuration du serveur à l'aide `--config-file` argument.
-
-!!! warning "Avertissement"
-    Il n'est pas recommandé de charger la configuration du serveur de production dans `clickhouse-local` parce que les données peuvent être endommagées en cas d'erreur humaine.
-
-## Utilisation {#usage}
-
-Utilisation de base:
-
-``` bash
-$ clickhouse-local --structure "table_structure" --input-format "format_of_incoming_data" -q "query"
-```
-
-Argument:
-
--   `-S`, `--structure` — table structure for input data.
--   `-if`, `--input-format` — input format, `TSV` par défaut.
--   `-f`, `--file` — path to data, `stdin` par défaut.
--   `-q` `--query` — queries to execute with `;` comme délimiteur.
--   `-N`, `--table` — table name where to put output data, `table` par défaut.
--   `-of`, `--format`, `--output-format` — output format, `TSV` par défaut.
--   `--stacktrace` — whether to dump debug output in case of exception.
--   `--verbose` — more details on query execution.
--   `-s` — disables `stderr` journalisation.
--   `--config-file` — path to configuration file in same format as for ClickHouse server, by default the configuration empty.
--   `--help` — arguments references for `clickhouse-local`.
-
-Il existe également des arguments pour chaque variable de configuration de ClickHouse qui sont plus couramment utilisés à la place de `--config-file`.
-
-## Exemple {#examples}
-
-``` bash
-$ echo -e "1,2\n3,4" | clickhouse-local -S "a Int64, b Int64" -if "CSV" -q "SELECT * FROM table"
-Read 2 rows, 32.00 B in 0.000 sec., 5182 rows/sec., 80.97 KiB/sec.
-1   2
-3   4
-```
-
-Exemple précédent est le même que:
-
-``` bash
-$ echo -e "1,2\n3,4" | clickhouse-local -q "CREATE TABLE table (a Int64, b Int64) ENGINE = File(CSV, stdin); SELECT a, b FROM table; DROP TABLE table"
-Read 2 rows, 32.00 B in 0.000 sec., 4987 rows/sec., 77.93 KiB/sec.
-1   2
-3   4
-```
-
-Maintenant, nous allons sortie utilisateur de mémoire pour chaque utilisateur Unix:
-
-``` bash
-$ ps aux | tail -n +2 | awk '{ printf("%s\t%s\n", $1, $4) }' | clickhouse-local -S "user String, mem Float64" -q "SELECT user, round(sum(mem), 2) as memTotal FROM table GROUP BY user ORDER BY memTotal DESC FORMAT Pretty"
-```
-
-``` text
-Read 186 rows, 4.15 KiB in 0.035 sec., 5302 rows/sec., 118.34 KiB/sec.
-┏━━━━━━━━━━┳━━━━━━━━━━┓
-┃ user     ┃ memTotal ┃
-┡━━━━━━━━━━╇━━━━━━━━━━┩
-│ bayonet  │    113.5 │
-├──────────┼──────────┤
-│ root     │      8.8 │

----
-
-# Combinateurs De Fonction D'Agrégat {#aggregate_functions_combinators}
-
-Le nom d'une fonction d'agrégat peut avoir un suffixe ajouté. Cela change la façon dont la fonction d'agrégation fonctionne.
-
-## -Si {#agg-functions-combinator-if}
-
-The suffix -If can be appended to the name of any aggregate function. In this case, the aggregate function accepts an extra argument – a condition (Uint8 type). The aggregate function processes only the rows that trigger the condition. If the condition was not triggered even once, it returns a default value (usually zeros or empty strings).
-
-Exemple: `sumIf(column, cond)`, `countIf(cond)`, `avgIf(x, cond)`, `quantilesTimingIf(level1, level2)(x, cond)`, `argMinIf(arg, val, cond)` et ainsi de suite.
-
-Avec les fonctions d'agrégat conditionnel, vous pouvez calculer des agrégats pour plusieurs conditions à la fois, sans utiliser de sous-requêtes et `JOIN`s. Par exemple, dans Yandex.Metrica, les fonctions d'agrégat conditionnel sont utilisées pour implémenter la fonctionnalité de comparaison de segment.
-
-## -Tableau {#agg-functions-combinator-array}
-
-Le Tableau suffixe peut être ajouté à toute fonction d'agrégation. Dans ce cas, la fonction d'agrégation des arguments de la ‘Array(T)’ type (tableaux) au lieu de ‘T’ tapez les arguments. Si la fonction aggregate accepte plusieurs arguments, il doit s'agir de tableaux de longueurs égales. Lors du traitement des tableaux, la fonction d'agrégation fonctionne comme la fonction d'agrégation d'origine sur tous les éléments du tableau.
-
-Exemple 1: `sumArray(arr)` - Totalise tous les éléments de tous ‘arr’ tableau. Dans cet exemple, il aurait pu être écrit plus simplement: `sum(arraySum(arr))`.
-
-Exemple 2: `uniqArray(arr)` – Counts the number of unique elements in all ‘arr’ tableau. Cela pourrait être fait d'une manière plus facile: `uniq(arrayJoin(arr))` mais ce n'est pas toujours possible d'ajouter des ‘arrayJoin’ pour une requête.
-
-\- Si et-tableau peut être combiné. Cependant, ‘Array’ doit venir en premier, puis ‘If’. Exemple: `uniqArrayIf(arr, cond)`, `quantilesTimingArrayIf(level1, level2)(arr, cond)`. En raison de cet ordre, le ‘cond’ argument ne sera pas un tableau.
-
-## -État {#agg-functions-combinator-state}
-
-Si vous appliquez ce combinateur, la fonction d'agrégation ne renvoie pas la valeur résultante (par exemple le nombre de valeurs uniques pour [uniq](reference.md#agg_function-uniq) la fonction), mais un état intermédiaire de l'agrégation (pour `uniq`, c'est la table de hachage pour calculer le nombre de valeurs uniques). C'est un `AggregateFunction(...)` qui peuvent être utilisés pour un traitement ultérieur ou stockés dans un tableau pour terminer l'agrégation plus tard.
-
-Pour travailler avec ces états, utilisez:
-
--   [AggregatingMergeTree](../../engines/table-engines/mergetree-family/aggregatingmergetree.md) tableau moteur.
--   [finalizeAggregation](../../sql-reference/functions/other-functions.md#function-finalizeaggregation) fonction.
--   [runningAccumulate](../../sql-reference/functions/other-functions.md#function-runningaccumulate) fonction.
--   [-Fusionner](#aggregate_functions_combinators-merge) combinator.
--   [-MergeState](#aggregate_functions_combinators-mergestate) combinator.
-
-## -Fusionner {#aggregate_functions_combinators-merge}
-
-Si vous appliquez ce combinateur, la fonction d'agrégation prend l'état d'agrégation intermédiaire comme argument, combine les États pour terminer l'agrégation et renvoie la valeur résultante.
-
-## -MergeState {#aggregate_functions_combinators-mergestate}
-
-Fusionne les États d'agrégation intermédiaires de la même manière que le combinateur-Merge. Cependant, il ne renvoie pas la valeur résultante, mais un État d'agrégation intermédiaire, similaire au combinateur-State.
-
-## - ForEach {#agg-functions-combinator-foreach}
-
-Convertit une fonction d'agrégation pour les tables en une fonction d'agrégation pour les tableaux qui agrège les éléments de tableau correspondants et renvoie un tableau de résultats. Exemple, `sumForEach` pour les tableaux `[1, 2]`, `[3, 4, 5]`et`[6, 7]`renvoie le résultat `[10, 13, 5]` après avoir additionné les éléments de tableau correspondants.
-
-## - OrDefault {#agg-functions-combinator-ordefault}
-
-Modifie le comportement d'une fonction d'agrégat.
-
-Si une fonction d'agrégation n'a pas de valeurs d'entrée, avec ce combinateur, elle renvoie la valeur par défaut pour son type de données de retour. S'applique aux fonctions d'agrégation qui peuvent prendre des données d'entrée vides.
-
-`-OrDefault` peut être utilisé avec d'autres combinators.
-
-**Syntaxe**
-
-``` sql
-<aggFunction>OrDefault(x)
-```
-
-**Paramètre**
-
--   `x` — Aggregate function parameters.
-
-**Valeurs renvoyées**
-
-Renvoie la valeur par défaut du type de retour d'une fonction d'agrégation s'il n'y a rien à agréger.
-
-Le Type dépend de la fonction d'agrégation utilisée.
-
-**Exemple**
-
-Requête:
-
-``` sql
-SELECT avg(number), avgOrDefault(number) FROM numbers(0)
-```
-
-Résultat:
-
-``` text
-┌─avg(number)─┬─avgOrDefault(number)─┐
-│         nan │                    0 │
-└─────────────┴──────────────────────┘
-```
-
-Également `-OrDefault` peut être utilisé avec un autre combinateur. Il est utile lorsque la fonction d'agrégation n'accepte pas l'entrée vide.
-
-Requête:
-
-``` sql
-SELECT avgOrDefaultIf(x, x > 10)
-FROM
-(
-    SELECT toDecimal32(1.23, 2) AS x
-)
-```
-
-Résultat:
-
-``` text
-┌─avgOrDefaultIf(x, greater(x, 10))─┐
-│                              0.00 │
-└───────────────────────────────────┘
-```
-
-## - OrNull {#agg-functions-combinator-ornull}
-
-Modifie le comportement d'une fonction d'agrégat.
-
-Ce combinateur convertit un résultat d'une fonction d'agrégation à l' [Nullable](../data-types/nullable.md) type de données. Si la fonction d'agrégation n'a pas de valeurs à calculer elle renvoie [NULL](../syntax.md#null-literal).
-
-`-OrNull` peut être utilisé avec d'autres combinators.
-
-**Syntaxe**
-
-``` sql
-<aggFunction>OrNull(x)
-```
-
-**Paramètre**
-
--   `x` — Aggregate function parameters.
-
-**Valeurs renvoyées**
-
--   Le résultat de la fonction d'agrégat, converti en `Nullable` type de données.
--   `NULL` si il n'y a rien à s'agréger.
-
-Type: `Nullable(aggregate function return type)`.
-
-**Exemple**
-
-Ajouter `-orNull` à la fin de la fonction d'agrégation.
-
-Requête:
-
-``` sql
-SELECT sumOrNull(number), toTypeName(sumOrNull(number)) FROM numbers(10) WHERE number > 10
-```
-
-Résultat:
-
-``` text
-┌─sumOrNull(number)─┬─toTypeName(sumOrNull(number))─┐
-│              ᴺᵁᴸᴸ │ Nullable(UInt64)              │
-└───────────────────┴───────────────────────────────┘
-```
-
-Également `-OrNull` peut être utilisé avec un autre combinateur. Il est utile lorsque la fonction d'agrégation n'accepte pas l'entrée vide.
-
-Requête:
-
-``` sql
-SELECT avgOrNullIf(x, x > 10)
-FROM
-(
-    SELECT toDecimal32(1.23, 2) AS x
-)
-```
-
-Résultat:
-
-``` text
-┌─avgOrNullIf(x, greater(x, 10))─┐
-│                           ᴺᵁᴸᴸ │
-└────────────────────────────────┘
-```
-
-## -Resample {#agg-functions-combinator-resample}
-
-Permet de diviser les données en groupes, puis séparément agrège les données de ces groupes. Les groupes sont créés en divisant les valeurs d'une colonne en intervalles.
-
-``` sql
-<aggFunction>Resample(start, end, step)(<aggFunction_params>, resampling_key)
-```
-
-**Paramètre**
-
--   `start` — Starting value of the whole required interval for `resampling_key` valeur.
--   `stop` — Ending value of the whole required interval for `resampling_key` valeur. L'ensemble de l'intervalle ne comprend pas les `stop` valeur `[start, stop)`.
--   `step` — Step for separating the whole interval into subintervals. The `aggFunction` est exécuté sur chacun de ces sous-intervalles indépendamment.
--   `resampling_key` — Column whose values are used for separating data into intervals.
--   `aggFunction_params` — `aggFunction` paramètre.
-
-**Valeurs renvoyées**
-
--   Tableau de `aggFunction` les résultats pour chaque subinterval.
-
-**Exemple**
-
-Envisager l' `people` le tableau avec les données suivantes:
-
-``` text
-┌─name───┬─age─┬─wage─┐
-│ John   │  16 │   10 │
-│ Alice  │  30 │   15 │
-│ Mary   │  35 │    8 │
-│ Evelyn │  48 │ 11.5 │
-│ David  │  62 │  9.9 │
-│ Brian  │  60 │   16 │
-└────────┴─────┴──────┘
-```
-
-Obtenons les noms des personnes dont l'âge se trouve dans les intervalles de `[30,60)` et `[60,75)`. Puisque nous utilisons la représentation entière pour l'âge, nous obtenons des âges dans le `[30, 59]` et `[60,74]` intervalle.
-
-Pour agréger des noms dans un tableau, nous utilisons [grouperay](reference.md#agg_function-grouparray) fonction d'agrégation. Il faut un argument. Dans notre cas, c'est l' `name` colonne. Le `groupArrayResample` fonction devrait utiliser le `age` colonne pour agréger les noms par âge. Pour définir les intervalles requis, nous passons le `30, 75, 30` des arguments dans la `groupArrayResample` fonction.
-
-``` sql
-SELECT groupArrayResample(30, 75, 30)(name, age) FROM people
-```
-
-``` text
-┌─groupArrayResample(30, 75, 30)(name, age)─────┐
-│ [['Alice','Mary','Evelyn'],['David','Brian']] │
-└───────────────────────────────────────────────┘
-```
-
-Considérez les résultats.
-
-`Jonh` est hors de l'échantillon parce qu'il est trop jeune. D'autres personnes sont distribués selon les intervalles d'âge.
-
-Maintenant, nous allons compter le nombre total de personnes et leur salaire moyen dans les intervalles d'âge.
-
-``` sql
-SELECT
-    countResample(30, 75, 30)(name, age) AS amount,
-    avgResample(30, 75, 30)(wage, age) AS avg_wage
-FROM people
-```
-
-``` text
-┌─amount─┬─avg_wage──────────────────┐
-│ [3,2]  │ [11.5,12.949999809265137] │
-└────────┴───────────────────────────┘

-
-# Les Fonctions D'Agrégation {#aggregate-functions}
-
-Les fonctions d'agrégation fonctionnent dans le [normal](http://www.sql-tutorial.com/sql-aggregate-functions-sql-tutorial) comme prévu par les experts de la base de données.
-
-Clickhouse prend également en charge:
-
--   [Fonctions d'agrégat paramétriques](parametric-functions.md#aggregate_functions_parametric) qui acceptent d'autres paramètres en plus des colonnes.
--   [Combinators](combinators.md#aggregate_functions_combinators), qui modifient le comportement des fonctions d'agrégation.
-
-## Le Traitement NULL {#null-processing}
-
-Au cours de l'agrégation, tous les `NULL`s sont ignorés.
-
-**Exemple:**
-
-Considérez ce tableau:
-
-``` text
-┌─x─┬────y─┐
-│ 1 │    2 │
-│ 2 │ ᴺᵁᴸᴸ │
-│ 3 │    2 │
-│ 3 │    3 │
-│ 3 │ ᴺᵁᴸᴸ │
-└───┴──────┘
-```
-
-Disons que vous devez totaliser les valeurs dans le `y` colonne:
-
-``` sql
-SELECT sum(y) FROM t_null_big
-```
-
-    ┌─sum(y)─┐
-    │      7 │
-    └────────┘
-
-Le `sum` la fonction d'interprète `NULL` comme `0`. En particulier, cela signifie que si la fonction reçoit en entrée d'une sélection où toutes les valeurs sont `NULL`, alors le résultat sera `0`, pas `NULL`.
-
-Maintenant, vous pouvez utiliser le `groupArray` fonction pour créer un tableau à partir `y` colonne:
-
-``` sql
-SELECT groupArray(y) FROM t_null_big
-```
-
-``` text
-┌─groupArray(y)─┐
-│ [2,2,3]       │
-└───────────────┘
-```
-
-`groupArray` ne comprend pas `NULL` dans le tableau résultant.

-# Fonctions D'Agrégat Paramétriques {#aggregate_functions_parametric}
-
-Some aggregate functions can accept not only argument columns (used for compression), but a set of parameters – constants for initialization. The syntax is two pairs of brackets instead of one. The first is for parameters, and the second is for arguments.
-
-## histogramme {#histogram}
-
-Calcule un histogramme adaptatif. Cela ne garantit pas des résultats précis.
-
-``` sql
-histogram(number_of_bins)(values)
-```
-
-Les fonctions utilise [Un Algorithme D'Arbre De Décision Parallèle En Continu](http://jmlr.org/papers/volume11/ben-haim10a/ben-haim10a.pdf). Les bordures des bacs d'histogramme sont ajustées au fur et à mesure que de nouvelles données entrent dans une fonction. Dans le cas courant, les largeurs des bacs ne sont pas égales.
-
-**Paramètre**
-
-`number_of_bins` — Upper limit for the number of bins in the histogram. The function automatically calculates the number of bins. It tries to reach the specified number of bins, but if it fails, it uses fewer bins.
-`values` — [Expression](../syntax.md#syntax-expressions) résultant en valeurs d'entrée.
-
-**Valeurs renvoyées**
-
--   [Tableau](../../sql-reference/data-types/array.md) de [Tuple](../../sql-reference/data-types/tuple.md) de le format suivant:
-
-        ```
-        [(lower_1, upper_1, height_1), ... (lower_N, upper_N, height_N)]
-        ```
-
-        - `lower` — Lower bound of the bin.
-        - `upper` — Upper bound of the bin.
-        - `height` — Calculated height of the bin.
-
-**Exemple**
-
-``` sql
-SELECT histogram(5)(number + 1)
-FROM (
-    SELECT *
-    FROM system.numbers
-    LIMIT 20
-)
-```
-
-``` text
-┌─histogram(5)(plus(number, 1))───────────────────────────────────────────┐
-│ [(1,4.5,4),(4.5,8.5,4),(8.5,12.75,4.125),(12.75,17,4.625),(17,20,3.25)] │
-└─────────────────────────────────────────────────────────────────────────┘
-```
-
-Vous pouvez visualiser un histogramme avec la [bar](../../sql-reference/functions/other-functions.md#function-bar) fonction, par exemple:
-
-``` sql
-WITH histogram(5)(rand() % 100) AS hist
-SELECT
-    arrayJoin(hist).3 AS height,
-    bar(height, 0, 6, 5) AS bar
-FROM
-(
-    SELECT *
-    FROM system.numbers
-    LIMIT 20
-)
-```
-
-``` text
-┌─height─┬─bar───┐

-│  5.625 │ ████▏ │
-│  5.625 │ ████▏ │
-│  3.375 │ ██▌   │

-
-Dans ce cas, vous devez vous rappeler que vous ne connaissez pas les frontières de la corbeille d'histogramme.

-## sequenceMatch(pattern)(timestamp, cond1, cond2, …) {#function-sequencematch}
-
-Vérifie si la séquence contient une chaîne d'événements qui correspond au modèle.
-
-``` sql
-sequenceMatch(pattern)(timestamp, cond1, cond2, ...)
-```
-
-!!! warning "Avertissement"
-    Les événements qui se produisent à la même seconde peuvent se situer dans la séquence dans un ordre indéfini affectant le résultat.
-
-**Paramètre**
-
--   `pattern` — Pattern string. See [Syntaxe du motif](#sequence-function-pattern-syntax).
-
--   `timestamp` — Column considered to contain time data. Typical data types are `Date` et `DateTime`. Vous pouvez également utiliser les prises en charge [UInt](../../sql-reference/data-types/int-uint.md) types de données.
-
--   `cond1`, `cond2` — Conditions that describe the chain of events. Data type: `UInt8`. Vous pouvez passer jusqu'à 32 arguments de condition. La fonction ne prend en compte que les événements décrits dans ces conditions. Si la séquence contient des données qui ne sont pas décrites dans une condition, la fonction les ignore.
-
-**Valeurs renvoyées**
-
--   1, si le profil correspond.
--   0, si le motif ne correspond pas.
-
-Type: `UInt8`.
-
-<a name="sequence-function-pattern-syntax"></a>
-**Syntaxe du motif**
-
--   `(?N)` — Matches the condition argument at position `N`. Les Conditions sont numérotées dans le `[1, 32]` gamme. Exemple, `(?1)` correspond à l'argument passé au `cond1` paramètre.
-
--   `.*` — Matches any number of events. You don't need conditional arguments to match this element of the pattern.
-
--   `(?t operator value)` — Sets the time in seconds that should separate two events. For example, pattern `(?1)(?t>1800)(?2)` correspond à des événements qui se produisent plus de 1800 secondes les uns des autres. Un nombre arbitraire d'événements peut se trouver entre ces événements. Vous pouvez utiliser l' `>=`, `>`, `<`, `<=` opérateur.
-
-**Exemple**
-
-Considérer les données dans le `t` table:
-
-``` text
-┌─time─┬─number─┐
-│    1 │      1 │
-│    2 │      3 │

-
-Effectuer la requête:
-
-``` sql

-└───────────────────────────────────────────────────────────────────────┘
-```
-
-La fonction a trouvé la chaîne d'événements où le numéro 2 suit le numéro 1. Il a sauté le numéro 3 entre eux, car le nombre n'est pas décrit comme un événement. Si nous voulons prendre ce nombre en compte lors de la recherche de l'événement de la chaîne donnée dans l'exemple, nous devrions en faire une condition.
-
-``` sql
-SELECT sequenceMatch('(?1)(?2)')(time, number = 1, number = 2, number = 3) FROM t
-```
-
-``` text
-┌─sequenceMatch('(?1)(?2)')(time, equals(number, 1), equals(number, 2), equals(number, 3))─┐

-└──────────────────────────────────────────────────────────────────────────────────────────┘
-```
-
-Dans ce cas, la fonction n'a pas pu trouver la chaîne d'événements correspondant au modèle, car l'événement pour le numéro 3 s'est produit entre 1 et 2. Si dans le même cas nous vérifions la condition pour le numéro 4, la séquence correspondrait au motif.

-## fenêtrefunnel {#windowfunnel}
-
-Recherche les chaînes d'événements dans une fenêtre de temps coulissante et calcule le nombre maximum d'événements qui se sont produits à partir de la chaîne.
-
-La fonction fonctionne selon l'algorithme:
-
--   La fonction recherche les données qui déclenchent la première condition de la chaîne et définit le compteur d'événements sur 1. C'est le moment où la fenêtre coulissante commence.
-
--   Si les événements de la chaîne se produisent séquentiellement dans la fenêtre, le compteur est incrémenté. Si la séquence d'événements est perturbée, le compteur n'est pas incrémenté.
-
--   Si les données ont plusieurs chaînes d'événements à différents points d'achèvement, la fonction affichera uniquement la taille de la chaîne la plus longue.
-
-**Syntaxe**
-
-``` sql
-windowFunnel(window, [mode])(timestamp, cond1, cond2, ..., condN)
-```
-
-**Paramètre**
-
--   `window` — Length of the sliding window in seconds.
--   `mode` - C'est un argument facultatif.
-    -   `'strict'` - Lorsque le `'strict'` est défini, le windowFunnel() applique des conditions uniquement pour les valeurs uniques.
--   `timestamp` — Name of the column containing the timestamp. Data types supported: [Date](../../sql-reference/data-types/date.md), [DateTime](../../sql-reference/data-types/datetime.md#data_type-datetime) et d'autres types entiers non signés (notez que même si timestamp prend en charge le `UInt64` type, sa valeur ne peut pas dépasser le maximum Int64, qui est 2^63 - 1).
--   `cond` — Conditions or data describing the chain of events. [UInt8](../../sql-reference/data-types/int-uint.md).

-## uniqUpTo (N) (x) {#uniquptonx}
-
-Calculates the number of different argument values ​​if it is less than or equal to N. If the number of different argument values is greater than N, it returns N + 1.
-
-Recommandé pour une utilisation avec de petites Ns, jusqu'à 10. La valeur maximale de N est de 100.
-
-Pour l'état d'une fonction d'agrégation, il utilise la quantité de mémoire égale à 1 + N \* de la taille d'une valeur d'octets.
-Pour les chaînes, il stocke un hachage non cryptographique de 8 octets. Soit le calcul est approchée pour les chaînes.
-
-La fonction fonctionne également pour plusieurs arguments.
-
-Cela fonctionne aussi vite que possible, sauf dans les cas où une grande valeur N est utilisée et le nombre de valeurs uniques est légèrement inférieur à N.
-
-Exemple d'utilisation:
-
-``` text
-Problem: Generate a report that shows only keywords that produced at least 5 unique users.
-Solution: Write in the GROUP BY query SearchPhrase HAVING uniqUpTo(4)(UserID) >= 5

-# Référence De La Fonction Agrégée {#aggregate-functions-reference}
-
-## compter {#agg_function-count}
-
-Compte le nombre de lignes ou de valeurs non NULL.
-
-ClickHouse prend en charge les syntaxes suivantes pour `count`:
-- `count(expr)` ou `COUNT(DISTINCT expr)`.
-- `count()` ou `COUNT(*)`. Le `count()` la syntaxe est spécifique à ClickHouse.
-
-**Paramètre**
-
-La fonction peut prendre:
-
--   Zéro des paramètres.
--   Un [expression](../syntax.md#syntax-expressions).
-
-**Valeur renvoyée**
-
--   Si la fonction est appelée sans paramètres, il compte le nombre de lignes.
--   Si l' [expression](../syntax.md#syntax-expressions) est passé, alors la fonction compte combien de fois cette expression retournée not null. Si l'expression renvoie un [Nullable](../../sql-reference/data-types/nullable.md)- tapez la valeur, puis le résultat de `count` séjours pas `Nullable`. La fonction renvoie 0 si l'expression est retournée `NULL` pour toutes les lignes.
-
-Dans les deux cas le type de la valeur renvoyée est [UInt64](../../sql-reference/data-types/int-uint.md).
-
-**Détail**
-
-Clickhouse soutient le `COUNT(DISTINCT ...)` syntaxe. Le comportement de cette construction dépend de la [count_distinct_implementation](../../operations/settings/settings.md#settings-count_distinct_implementation) paramètre. Il définit lequel des [uniq\*](#agg_function-uniq) fonctions est utilisée pour effectuer l'opération. La valeur par défaut est la [uniqExact](#agg_function-uniqexact) fonction.

-Le `SELECT count() FROM table` la requête n'est pas optimisé, car le nombre d'entrées dans la table n'est pas stockée séparément. Il choisit une petite colonne de la table et compte le nombre de valeurs qu'il contient.
-
-**Exemple**
-
-Exemple 1:
-
-``` sql
-SELECT count() FROM t
-```
-
-``` text
-┌─count()─┐
-│       5 │
-└─────────┘
-```
-
-Exemple 2:
-
-``` sql
-SELECT name, value FROM system.settings WHERE name = 'count_distinct_implementation'
-```
-
-``` text
-┌─name──────────────────────────┬─value─────┐
-│ count_distinct_implementation │ uniqExact │
-└───────────────────────────────┴───────────┘
-```
-
-``` sql
-SELECT count(DISTINCT num) FROM t
-```
-
-``` text
-┌─uniqExact(num)─┐
-│              3 │
-└────────────────┘
-```
-
-Cet exemple montre que `count(DISTINCT num)` est effectuée par le `uniqExact` en fonction de l' `count_distinct_implementation` valeur de réglage.
-
-## tout(x) {#agg_function-any}
-
-Sélectionne la première valeur rencontrée.
-La requête peut être exécutée dans n'importe quel ordre, et même dans un ordre différent à chaque fois, de sorte que le résultat de cette fonction est indéterminée.
-Pour obtenir un résultat déterminé, vous pouvez utiliser le ‘min’ ou ‘max’ fonction au lieu de ‘any’.
-
-Dans certains cas, vous pouvez compter sur l'ordre de l'exécution. Cela s'applique aux cas où SELECT provient d'une sous-requête qui utilise ORDER BY.
-
-Lorsqu'un `SELECT` la requête a l' `GROUP BY` ou au moins une fonction d'agrégat, ClickHouse (contrairement à MySQL) exige que toutes les expressions du `SELECT`, `HAVING`, et `ORDER BY` clauses être calculée à partir de clés ou de fonctions d'agrégation. En d'autres termes, chaque colonne sélectionnée dans la table doit être utilisée soit dans les clés, soit dans les fonctions d'agrégation. Pour obtenir un comportement comme dans MySQL, vous pouvez mettre les autres colonnes dans le `any` fonction d'agrégation.
-
-## anyHeavy (x) {#anyheavyx}
-
-Sélectionne une valeur fréquente à l'aide [poids lourds](http://www.cs.umd.edu/~samir/498/karp.pdf) algorithme. S'il y a une valeur qui se produit plus de la moitié des cas dans chacun des threads d'exécution de la requête, cette valeur est renvoyée. Normalement, le résultat est non déterministe.

-
-`HLL_precision` est le logarithme en base 2 du nombre de cellules dans [HyperLogLog](https://en.wikipedia.org/wiki/HyperLogLog). Facultatif, vous pouvez utiliser la fonction comme `uniqCombined(x[, ...])`. La valeur par défaut pour `HLL_precision` est 17, qui est effectivement 96 Ko d'espace(2 ^ 17 cellules, 6 bits chacune).
-
-**Valeur renvoyée**
-
--   Nombre [UInt64](../../sql-reference/data-types/int-uint.md)numéro de type.
-
-**Détails de mise en œuvre**
-
-Fonction:
-
--   Calcule un hachage (hachage 64 bits pour `String` et 32 bits sinon) pour tous les paramètres dans l'agrégat, puis l'utilise dans les calculs.
-
--   Utilise une combinaison de trois algorithmes: tableau, table de hachage et HyperLogLog avec une table de correction d'erreur.
-
-        For a small number of distinct elements, an array is used. When the set size is larger, a hash table is used. For a larger number of elements, HyperLogLog is used, which will occupy a fixed amount of memory.
-
--   Fournit le résultat de manière déterministe (cela ne dépend pas de l'ordre de traitement de la requête).
-
-!!! note "Note"
-    Comme il utilise le hachage 32 bits pour non-`String` type, le résultat aura une erreur très élevée pour les cardinalités significativement plus grandes que `UINT_MAX` (erreur va augmenter rapidement après quelques dizaines de milliards de valeurs distinctes), donc dans ce cas, vous devez utiliser [uniqCombined64](#agg_function-uniqcombined64)
-
-Par rapport à la [uniq](#agg_function-uniq) la fonction, la `uniqCombined`:
-
--   Consomme plusieurs fois moins de mémoire.
--   Calcule avec plusieurs fois plus de précision.
--   A généralement des performances légèrement inférieures. Dans certains scénarios, `uniqCombined` peut faire mieux que `uniq` par exemple, avec des requêtes distribuées qui transmettent un grand nombre d'agrégation des états sur le réseau.

--   A [UInt64](../../sql-reference/data-types/int-uint.md)numéro de type.
-
-**Détails de mise en œuvre**
-
-Fonction:
-
--   Calcule un hachage pour tous les paramètres de l'agrégat, puis l'utilise dans les calculs.
-
--   Utilise L'algorithme HyperLogLog pour approximer le nombre de valeurs d'argument différentes.
-
-        212 5-bit cells are used. The size of the state is slightly more than 2.5 KB. The result is not very accurate (up to ~10% error) for small data sets (<10K elements). However, the result is fairly accurate for high-cardinality data sets (10K-100M), with a maximum error of ~1.6%. Starting from 100M, the estimation error increases, and the function will return very inaccurate results for data sets with extremely high cardinality (1B+ elements).
-
--   Fournit le résultat déterminé (il ne dépend pas de l'ordre de traitement de la requête).

-```
-
-L'utilisation de la `uniqExact` fonction si vous avez absolument besoin d'un résultat exact. Sinon l'utilisation de la [uniq](#agg_function-uniq) fonction.

-Les valeurs peuvent être ajoutées au tableau dans une (indéterminée) de commande.
-
-La deuxième version (avec le `max_size` paramètre) limite la taille du tableau résultant à `max_size` élément.
-Exemple, `groupArray (1) (x)` est équivalent à `[any (x)]`.

-## quantileTDigestWeighted {#quantiletdigestweighted}
-
-Calcule une approximation [quantile](https://en.wikipedia.org/wiki/Quantile) d'une séquence de données numériques utilisant [t-digest](https://github.com/tdunning/t-digest/blob/master/docs/t-digest-paper/histo.pdf) algorithme. La fonction prend en compte le poids de chaque séquence de membre. L'erreur maximale est de 1%. La consommation de mémoire est `log(n)`, où `n` est un certain nombre de valeurs.
-
-La performance de la fonction est inférieure à la performance de [quantile](#quantile) ou [quantileTiming](#quantiletiming). En termes de rapport entre la taille de L'état et la précision, cette fonction est bien meilleure que `quantile`.
-
-Le résultat dépend de l'ordre d'exécution de la requête et n'est pas déterministe.

-## stochasticLinearRegression {#agg_functions-stochasticlinearregression}
-
-Cette fonction implémente la régression linéaire stochastique. Il prend en charge les paramètres personnalisés pour le taux d'apprentissage, le coefficient de régularisation L2, la taille de mini-lot et a peu de méthodes pour mettre à jour les poids ([Adam](https://en.wikipedia.org/wiki/Stochastic_gradient_descent#Adam) (utilisé par défaut), [simple SGD](https://en.wikipedia.org/wiki/Stochastic_gradient_descent), [Élan](https://en.wikipedia.org/wiki/Stochastic_gradient_descent#Momentum), [Nesterov](https://mipt.ru/upload/medialibrary/d7e/41-91.pdf)).
-
-### Paramètre {#agg_functions-stochasticlinearregression-parameters}
-
-Il y a 4 paramètres personnalisables. Ils sont passés à la fonction séquentiellement, mais il n'est pas nécessaire de passer tous les quatre-les valeurs par défaut seront utilisées, mais un bon modèle nécessite un réglage des paramètres.
-
-``` text
-stochasticLinearRegression(1.0, 1.0, 10, 'SGD')
-```
-
-1.  `learning rate` est le coefficient sur la longueur de l'étape, lorsque l'étape de descente de gradient est effectuée. Un taux d'apprentissage trop élevé peut entraîner des poids infinis du modèle. Par défaut est `0.00001`.
-2.  `l2 regularization coefficient` ce qui peut aider à éviter le surajustement. Par défaut est `0.1`.
-3.  `mini-batch size` définit le nombre d'éléments, dont les gradients seront calculés et additionnés pour effectuer une étape de descente de gradient. La descente stochastique Pure utilise un élément, mais avoir de petits lots (environ 10 éléments) rend les étapes de gradient plus stables. Par défaut est `15`.
-4.  `method for updating weights` ils sont: `Adam` (par défaut), `SGD`, `Momentum`, `Nesterov`. `Momentum` et `Nesterov` nécessitent un peu plus de calculs et de mémoire, mais ils sont utiles en termes de vitesse de convergence et de stabilité des méthodes de gradient stochastique.
-
-### Utilisation {#agg_functions-stochasticlinearregression-usage}
-
-`stochasticLinearRegression` est utilisé en deux étapes: ajustement du modèle et prédiction sur de nouvelles données. Afin de correspondre le modèle et l'enregistrer son état pour utilisation ultérieure nous utilisons `-State` combinator, qui enregistre essentiellement l'état (poids du modèle, etc.).
-Pour prédire nous utilisons la fonction [evalMLMethod](../functions/machine-learning-functions.md#machine_learning_methods-evalmlmethod) qui prend un état comme un argument ainsi que des fonctionnalités à prévoir sur.
-
-<a name="stochasticlinearregression-usage-fitting"></a>
-
-**1.** Raccord
-
-Une telle requête peut être utilisé.
-
-``` sql
-CREATE TABLE IF NOT EXISTS train_data
-(
-    param1 Float64,
-    param2 Float64,
-    target Float64
-) ENGINE = Memory;
-
-CREATE TABLE your_model ENGINE = Memory AS SELECT
-stochasticLinearRegressionState(0.1, 0.0, 5, 'SGD')(target, param1, param2)
-AS state FROM train_data;
-```
-
-Ici, nous devons également insérer des données dans `train_data` table. Le nombre de paramètres n'est pas fixe, il dépend uniquement du nombre d'arguments, passés dans `linearRegressionState`. Ils doivent tous être des valeurs numériques.
-Notez que la colonne avec la valeur cible (que nous aimerions apprendre à prédire) est insérée comme premier argument.
-
-**2.** Prédire
-
-Après avoir enregistré un État dans la table, nous pouvons l'utiliser plusieurs fois pour la prédiction, ou même fusionner avec d'autres États et créer de nouveaux modèles encore meilleurs.
-
-``` sql
-WITH (SELECT state FROM your_model) AS model SELECT
-evalMLMethod(model, param1, param2) FROM test_data
-```
-
-La requête renvoie une colonne de valeurs prédites. Notez que le premier argument de `evalMLMethod` être `AggregateFunctionState` objet, sont ensuite des colonnes de fonctionnalités.
-
-`test_data` est un tableau comme `train_data` mais peut ne pas contenir de valeur cible.
-
-### Note {#agg_functions-stochasticlinearregression-notes}
-
-1.  Pour fusionner deux modèles l'utilisateur peut créer une telle requête:
-    `sql  SELECT state1 + state2 FROM your_models`
-    où `your_models` le tableau contient les deux modèles. Cette requête renvoie la nouvelle `AggregateFunctionState` objet.
-
-2.  L'utilisateur peut récupérer les poids du modèle pour ses propres fins, sans enregistrer le modèle, si aucune `-State` combinator est utilisé.
-    `sql  SELECT stochasticLinearRegression(0.01)(target, param1, param2) FROM train_data`
-    Une telle requête s'adaptera au Modèle et retournera ses poids-d'abord sont des poids, qui correspondent aux paramètres du modèle, le dernier est un biais. Ainsi, dans l'exemple ci-dessus, la requête renvoie une colonne avec 3 valeurs.

-
-Les paramètres sont exactement les mêmes que dans stochasticLinearRegression:
-`learning rate`, `l2 regularization coefficient`, `mini-batch size`, `method for updating weights`.
-Pour plus d'informations, voir [paramètre](#agg_functions-stochasticlinearregression-parameters).

-    See the `Fitting` section in the [stochasticLinearRegression](#stochasticlinearregression-usage-fitting) description.
-
-    Predicted labels have to be in \[-1, 1\].
-
-1.  Prédire
-
-<!-- -->
-
-    Using saved state we can predict probability of object having label `1`.
-
-    ``` sql
-    WITH (SELECT state FROM your_model) AS model SELECT
-    evalMLMethod(model, param1, param2) FROM test_data
-    ```
-
-    The query will return a column of probabilities. Note that first argument of `evalMLMethod` is `AggregateFunctionState` object, next are columns of features.
-
-    We can also set a bound of probability, which assigns elements to different labels.
-
-    ``` sql
-    SELECT ans < 1.1 AND ans > 0.5 FROM
-    (WITH (SELECT state FROM your_model) AS model SELECT
-    evalMLMethod(model, param1, param2) AS ans FROM test_data)
-    ```
-
-    Then the result will be labels.
-
-    `test_data` is a table like `train_data` but may not contain target value.

-# AggregateFunction(name, types_of_arguments…) {#data-type-aggregatefunction}
-
-Aggregate functions can have an implementation-defined intermediate state that can be serialized to an AggregateFunction(…) data type and stored in a table, usually, by means of [une vue matérialisée](../../sql-reference/statements/create.md#create-view). La manière courante de produire un État de fonction d'agrégat est d'appeler la fonction d'agrégat avec le `-State` suffixe. Pour obtenir le résultat final de l'agrégation dans l'avenir, vous devez utiliser la même fonction d'agrégation avec la `-Merge`suffixe.
-
-`AggregateFunction` — parametric data type.
-
-**Paramètre**
-
--   Nom de la fonction d'agrégation.
-
-        If the function is parametric, specify its parameters too.
-
--   Types des arguments de la fonction d'agrégation.
-
-**Exemple**
-
-``` sql
-CREATE TABLE t
-(
-    column1 AggregateFunction(uniq, UInt64),
-    column2 AggregateFunction(anyIf, String, UInt8),
-    column3 AggregateFunction(quantiles(0.5, 0.9), UInt64)
-) ENGINE = ...
-```
-
-[uniq](../../sql-reference/aggregate-functions/reference.md#agg_function-uniq), anyIf ([tout](../../sql-reference/aggregate-functions/reference.md#agg_function-any)+[Si](../../sql-reference/aggregate-functions/combinators.md#agg-functions-combinator-if)) et [les quantiles](../../sql-reference/aggregate-functions/reference.md) les fonctions d'agrégation sont-elles prises en charge dans ClickHouse.
-
-## Utilisation {#usage}
-
-### Insertion De Données {#data-insertion}
-
-Pour insérer des données, utilisez `INSERT SELECT` avec le regroupement d' `-State`- fonction.
-
-**Exemples de fonction**
-
-``` sql
-uniqState(UserID)
-quantilesState(0.5, 0.9)(SendTiming)
-```
-
-Contrairement aux fonctions correspondantes `uniq` et `quantiles`, `-State`- les fonctions renvoient l'état, au lieu de la valeur finale. En d'autres termes, ils renvoient une valeur de `AggregateFunction` type.
-
-Dans les résultats de `SELECT` requête, les valeurs de `AggregateFunction` type ont une représentation binaire spécifique à l'implémentation pour tous les formats de sortie ClickHouse. Si les données de vidage dans, par exemple, `TabSeparated` format avec `SELECT` requête, puis ce vidage peut être chargé en utilisant `INSERT` requête.
-
-### Sélection De Données {#data-selection}
-
-Lors de la sélection des données `AggregatingMergeTree` table, utilisez `GROUP BY` et les mêmes fonctions d'agrégat que lors de l'insertion de données, mais en utilisant `-Merge`suffixe.
-
-Une fonction d'agrégation avec `-Merge` suffixe prend un ensemble d'états, les combine, et renvoie le résultat complet de l'agrégation de données.
-
-Par exemple, les deux requêtes suivantes retournent le même résultat:
-
-``` sql
-SELECT uniq(UserID) FROM table
-
-SELECT uniqMerge(state) FROM (SELECT uniqState(UserID) AS state FROM table GROUP BY RegionID)
-```
-
-## Exemple D'Utilisation {#usage-example}
-
-Voir [AggregatingMergeTree](../../engines/table-engines/mergetree-family/aggregatingmergetree.md) Description du moteur.

----
-
-# Array(t) {#data-type-array}
-
-Un tableau de `T`les éléments de type. `T` peut être n'importe quel type de données, y compris un tableau.
-
-## La création d'un Tableau {#creating-an-array}
-
-Vous pouvez utiliser une fonction pour créer un tableau:
-
-``` sql
-array(T)
-```
-
-Vous pouvez également utiliser des crochets.
-
-``` sql
-[]
-```
-
-Exemple de création d'un tableau:
-
-``` sql
-SELECT array(1, 2) AS x, toTypeName(x)
-```
-
-``` text
-┌─x─────┬─toTypeName(array(1, 2))─┐
-│ [1,2] │ Array(UInt8)            │
-└───────┴─────────────────────────┘
-```
-
-``` sql
-SELECT [1, 2] AS x, toTypeName(x)
-```
-
-``` text
-┌─x─────┬─toTypeName([1, 2])─┐
-│ [1,2] │ Array(UInt8)       │
-└───────┴────────────────────┘
-```
-
-## Utilisation de Types de données {#working-with-data-types}
-
-Lors de la création d'un tableau à la volée, ClickHouse définit automatiquement le type d'argument comme le type de données le plus étroit pouvant stocker tous les arguments listés. S'il y a des [Nullable](nullable.md#data_type-nullable) ou littéral [NULL](../../sql-reference/syntax.md#null-literal) les valeurs, le type d'un élément de tableau devient également [Nullable](nullable.md).
-
-Si ClickHouse n'a pas pu déterminer le type de données, il génère une exception. Par exemple, cela se produit lorsque vous essayez de créer un tableau avec des chaînes et des nombres simultanément (`SELECT array(1, 'a')`).
-
-Exemples de détection automatique de type de données:
-
-``` sql
-SELECT array(1, 2, NULL) AS x, toTypeName(x)
-```
-
-``` text
-┌─x──────────┬─toTypeName(array(1, 2, NULL))─┐
-│ [1,2,NULL] │ Array(Nullable(UInt8))        │
-└────────────┴───────────────────────────────┘
-```
-
-Si vous essayez de créer un tableau de types de données incompatibles, ClickHouse lève une exception:
-
-``` sql
-SELECT array(1, 'a')
-```
-
-``` text
-Received exception from server (version 1.1.54388):
-Code: 386. DB::Exception: Received from localhost:9000, 127.0.0.1. DB::Exception: There is no supertype for types UInt8, String because some of them are String/FixedString and some of them are not.

-# Datetime {#data_type-datetime}
-
-Permet de stocker un instant dans le temps, qui peut être exprimé comme une date de calendrier et une heure d'une journée.
-
-Syntaxe:
-
-``` sql
-DateTime([timezone])
-```
-
-Plage de valeurs prise en charge: \[1970-01-01 00:00:00, 2105-12-31 23:59:59\].
-
-Résolution: 1 seconde.
-
-## Utilisation Remarques {#usage-remarks}
-
-Le point dans le temps est enregistré en tant que [Le timestamp Unix](https://en.wikipedia.org/wiki/Unix_time), quel que soit le fuseau horaire ou l'heure d'été. En outre, l' `DateTime` type peut stocker le fuseau horaire qui est le même pour la colonne entière, qui affecte la façon dont les valeurs de la `DateTime` les valeurs de type sont affichées au format texte et comment les valeurs spécifiées en tant que chaînes sont analysées (‘2020-01-01 05:00:01’). Le fuseau horaire n'est pas stocké dans les lignes de la table (ou dans resultset), mais est stocké dans les métadonnées de la colonne.
-Une liste des fuseaux horaires pris en charge peut être trouvée dans le [Base de données de fuseau horaire IANA](https://www.iana.org/time-zones).
-Le `tzdata` paquet, contenant [Base de données de fuseau horaire IANA](https://www.iana.org/time-zones), doit être installé dans le système. L'utilisation de la `timedatectl list-timezones` commande pour lister les fuseaux horaires connus par un système local.
-
-Vous pouvez définir explicitement un fuseau horaire `DateTime`- tapez des colonnes lors de la création d'une table. Si le fuseau horaire n'est pas défini, ClickHouse utilise la valeur [fuseau](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) paramètre dans les paramètres du serveur ou les paramètres du système d'exploitation au moment du démarrage du serveur ClickHouse.
-
-Le [clickhouse-client](../../interfaces/cli.md) applique le fuseau horaire du serveur par défaut si un fuseau horaire n'est pas explicitement défini lors de l'initialisation du type de données. Pour utiliser le fuseau horaire du client, exécutez `clickhouse-client` avec l' `--use_client_time_zone` paramètre.
-
-Clickhouse affiche les valeurs dans `YYYY-MM-DD hh:mm:ss` format de texte par défaut. Vous pouvez modifier la sortie avec le [formatDateTime](../../sql-reference/functions/date-time-functions.md#formatdatetime) fonction.
-
-Lorsque vous insérez des données dans ClickHouse, vous pouvez utiliser différents formats de chaînes de date et d'heure, en fonction de la valeur du [date_time_input_format](../../operations/settings/settings.md#settings-date_time_input_format) paramètre.
-
-## Exemple {#examples}
-
-**1.** Création d'une table avec un `DateTime`- tapez la colonne et insérez des données dedans:
-
-``` sql
-CREATE TABLE dt
-(
-    `timestamp` DateTime('Europe/Moscow'),
-    `event_id` UInt8
-)
-ENGINE = TinyLog;
-```
-
-``` sql
-INSERT INTO dt Values (1546300800, 1), ('2019-01-01 00:00:00', 2);
-```
-
-``` sql
-SELECT * FROM dt;
-```
-
-``` text
-┌───────────timestamp─┬─event_id─┐
-│ 2019-01-01 03:00:00 │        1 │

-└─────────────────────┴──────────┘
-```
-
--   Lors de l'insertion de datetime en tant qu'entier, il est traité comme un horodatage Unix (UTC). `1546300800` représenter `'2019-01-01 00:00:00'` L'UTC. Cependant, comme `timestamp` la colonne a `Europe/Moscow` (UTC+3) fuseau horaire spécifié, lors de la sortie en tant que chaîne, la valeur sera affichée comme `'2019-01-01 03:00:00'`
--   Lors de l'insertion d'une valeur de chaîne en tant que datetime, elle est traitée comme étant dans le fuseau horaire de la colonne. `'2019-01-01 00:00:00'` sera considérée comme étant en `Europe/Moscow` fuseau horaire et enregistré sous `1546290000`.
-
-**2.** Le filtrage sur `DateTime` valeur
-
-``` sql
-SELECT * FROM dt WHERE timestamp = toDateTime('2019-01-01 00:00:00', 'Europe/Moscow')
-```
-
-``` text
-┌───────────timestamp─┬─event_id─┐
-│ 2019-01-01 00:00:00 │        2 │
-└─────────────────────┴──────────┘
-```
-
-`DateTime` les valeurs de colonne peuvent être filtrées à l'aide d'une `WHERE` prédicat. Elle sera convertie `DateTime` automatiquement:
-
-``` sql
-SELECT * FROM dt WHERE timestamp = '2019-01-01 00:00:00'
-```
-
-``` text
-┌───────────timestamp─┬─event_id─┐
-│ 2019-01-01 03:00:00 │        1 │
-└─────────────────────┴──────────┘
-```
-
-**3.** Obtenir un fuseau horaire pour un `DateTime`colonne de type:
-
-``` sql
-SELECT toDateTime(now(), 'Europe/Moscow') AS column, toTypeName(column) AS x
-```
-
-``` text
-┌──────────────column─┬─x─────────────────────────┐
-│ 2019-10-16 04:12:04 │ DateTime('Europe/Moscow') │
-└─────────────────────┴───────────────────────────┘
-```
-
-**4.** Conversion de fuseau horaire
-
-``` sql
-SELECT
-toDateTime(timestamp, 'Europe/London') as lon_time,
-toDateTime(timestamp, 'Europe/Moscow') as mos_time
-FROM dt
-```
-

-# Décimal (P, S), Décimal32 (S), Décimal64 (S), Décimal128 (S) {#decimalp-s-decimal32s-decimal64s-decimal128s}
-
-Nombres à points fixes signés qui conservent la précision pendant les opérations d'addition, de soustraction et de multiplication. Pour la division, les chiffres les moins significatifs sont ignorés (non arrondis).
-
-## Paramètre {#parameters}
-
--   P-précision. Plage valide: \[1: 38 \]. Détermine le nombre de chiffres décimaux nombre peut avoir (fraction y compris).
--   S - échelle. Plage valide: \[0: P \]. Détermine le nombre de chiffres décimaux fraction peut avoir.
-
-En fonction de P Paramètre Valeur décimal (P, S) est un synonyme de:
-- P à partir de \[ 1: 9\] - Pour Décimal32 (S)
-- P à partir de \[10: 18\] - pour Décimal64 (S)
-- P à partir de \[19: 38\] - pour Décimal128 (S)
-
-## Plages De Valeurs Décimales {#decimal-value-ranges}
-
--   Décimal32 (S) - ( -1 \* 10^(9 - S), 1 \* 10^(9-S) )
--   Décimal64 (S) - ( -1 \* 10^(18 - S), 1 \* 10^(18-S) )
--   Décimal128 (S) - ( -1 \* 10^(38 - S), 1 \* 10^(38-S) )
-
-Par exemple, Decimal32(4) peut contenir des nombres de -99999.9999 à 99999.9999 avec 0,0001 étape.
-
-## Représentation Interne {#internal-representation}
-
-En interne, les données sont représentées comme des entiers signés normaux avec une largeur de bit respective. Les plages de valeurs réelles qui peuvent être stockées en mémoire sont un peu plus grandes que celles spécifiées ci-dessus, qui sont vérifiées uniquement lors de la conversion à partir d'une chaîne.
-
-Parce que les processeurs modernes ne prennent pas en charge les entiers 128 bits nativement, les opérations sur Decimal128 sont émulées. Pour cette raison, Decimal128 fonctionne significativement plus lentement que Decimal32 / Decimal64.
-
-## Opérations et type de résultat {#operations-and-result-type}
-
-Les opérations binaires sur le résultat décimal dans le type de résultat plus large (avec n'importe quel ordre d'arguments).
-
--   `Decimal64(S1) <op> Decimal32(S2) -> Decimal64(S)`
--   `Decimal128(S1) <op> Decimal32(S2) -> Decimal128(S)`
--   `Decimal128(S1) <op> Decimal64(S2) -> Decimal128(S)`
-
-Règles pour l'échelle:
-
--   ajouter, soustraire: S = max (S1, S2).
--   multuply: S = S1 + S2.
--   diviser: S = S1.
-
-Pour des opérations similaires entre décimal et entier, le résultat est Décimal de la même taille qu'un argument.
-
-Les opérations entre Decimal et Float32 / Float64 ne sont pas définies. Si vous en avez besoin, vous pouvez explicitement lancer l'un des arguments en utilisant les builtins toDecimal32, toDecimal64, toDecimal128 ou toFloat32, toFloat64. Gardez à l'esprit que le résultat perdra de la précision et que la conversion de type est une opération coûteuse en calcul.
-
-Certaines fonctions sur le résultat de retour décimal comme Float64 (par exemple, var ou stddev). Les calculs intermédiaires peuvent toujours être effectués en décimal, ce qui peut conduire à des résultats différents entre les entrées Float64 et Decimal avec les mêmes valeurs.
-
-## Contrôles De Débordement {#overflow-checks}
-
-Pendant les calculs sur Décimal, des débordements entiers peuvent se produire. Les chiffres excessifs dans une fraction sont éliminés (non arrondis). Les chiffres excessifs dans la partie entière conduiront à une exception.
-
-``` sql
-SELECT toDecimal32(2, 4) AS x, x / 3

-
-``` text
-┌──────x─┬─divide(toDecimal32(2, 4), 3)─┐

-```
-
-Les contrôles de débordement entraînent un ralentissement des opérations. S'il est connu que les débordements ne sont pas possibles, il est logique de désactiver les contrôles en utilisant `decimal_check_overflow` paramètre. Lorsque des contrôles sont désactivés et le débordement se produit, le résultat sera faux:
-
-``` sql
-SET decimal_check_overflow = 0;
-SELECT toDecimal32(4.2, 8) AS x, 6 * x

-
-Les contrôles de débordement se produisent non seulement sur les opérations arithmétiques mais aussi sur la comparaison de valeurs:
-
-``` sql

-# Domaine {#domains}
-
-Les domaines sont des types spéciaux qui ajoutent des fonctionnalités supplémentaires au sommet du type de base existant, mais en laissant le format on-wire et on-disc du type de données sous-jacent intact. À l'heure actuelle, ClickHouse ne prend pas en charge les domaines définis par l'utilisateur.
-
-Vous pouvez utiliser des domaines partout type de base correspondant peut être utilisé, par exemple:
-
--   Créer une colonne d'un type de domaine
--   Valeurs de lecture / écriture depuis / vers la colonne de domaine
--   L'utiliser comme un indice si un type de base peut être utilisée comme un indice
--   Fonctions d'appel avec des valeurs de colonne de domaine
-
-### Fonctionnalités supplémentaires des domaines {#extra-features-of-domains}
-
--   Nom de type de colonne explicite dans `SHOW CREATE TABLE` ou `DESCRIBE TABLE`
--   Entrée du format convivial avec `INSERT INTO domain_table(domain_column) VALUES(...)`
--   Sortie au format convivial pour `SELECT domain_column FROM domain_table`
--   Chargement de données à partir d'une source externe dans un format convivial: `INSERT INTO domain_table FORMAT CSV ...`
-
-### Limitation {#limitations}
-
--   Impossible de convertir la colonne d'index du type de base en type de domaine via `ALTER TABLE`.
--   Impossible de convertir implicitement des valeurs de chaîne en valeurs de domaine lors de l'insertion de données d'une autre colonne ou table.
--   Le domaine n'ajoute aucune contrainte sur les valeurs stockées.

-
-Ou vous pouvez utiliser le domaine IPv4 comme clé:
-
-``` sql
-CREATE TABLE hits (url String, from IPv4) ENGINE = MergeTree() ORDER BY from;
-```
-
-`IPv4` le domaine prend en charge le format d'entrée personnalisé en tant que chaînes IPv4:
-
-``` sql
-INSERT INTO hits (url, from) VALUES ('https://wikipedia.org', '116.253.40.133')('https://clickhouse.tech', '183.247.232.58')('https://clickhouse.tech/docs/en/', '116.106.34.242');

-
-Les valeurs de domaine ne sont pas implicitement convertibles en types autres que `UInt32`.
-Si vous voulez convertir `IPv4` valeur à une chaîne, vous devez le faire explicitement avec `IPv4NumToString()` fonction:

-
-Ou coulé à un `UInt32` valeur:
-
-``` sql
-SELECT toTypeName(i), CAST(from as UInt32) as i FROM hits LIMIT 1;

-## IPv6 {#ipv6}
-
-`IPv6` est un domaine basé sur `FixedString(16)` tapez et sert de remplacement typé pour stocker des valeurs IPv6. Il fournit un stockage compact avec le format d'entrée-sortie convivial et les informations de type de colonne sur l'inspection.
-
-### Utilisation De Base {#basic-usage}
-
-``` sql
-CREATE TABLE hits (url String, from IPv6) ENGINE = MergeTree() ORDER BY url;
-
-DESCRIBE TABLE hits;
-```
-
-``` text
-┌─name─┬─type───┬─default_type─┬─default_expression─┬─comment─┬─codec_expression─┐

-
-Ou vous pouvez utiliser `IPv6` domaine comme l'un des principaux:
-
-``` sql
-CREATE TABLE hits (url String, from IPv6) ENGINE = MergeTree() ORDER BY from;
-```
-
-`IPv6` le domaine prend en charge l'entrée personnalisée en tant que chaînes IPv6:
-
-``` sql
-INSERT INTO hits (url, from) VALUES ('https://wikipedia.org', '2a02:aa08:e000:3100::2')('https://clickhouse.tech', '2001:44c8:129:2632:33:0:252:2')('https://clickhouse.tech/docs/en/', '2a02:e980:1e::1');

-└──────────────────┴──────────────────────────────────┘
-```
-
-Les valeurs de domaine ne sont pas implicitement convertibles en types autres que `FixedString(16)`.
-Si vous voulez convertir `IPv6` valeur à une chaîne, vous devez le faire explicitement avec `IPv6NumToString()` fonction:
-
-``` sql
-SELECT toTypeName(s), IPv6NumToString(from) as s FROM hits LIMIT 1;
-```

-toc_title: Enum
----
-
-# Enum {#enum}
-
-Type énuméré composé de valeurs nommées.
-
-Les valeurs nommées doivent être déclarées comme `'string' = integer` pair. ClickHouse ne stocke que des nombres, mais prend en charge les opérations avec les valeurs à travers leurs noms.
-
-Supports ClickHouse:
-
--   8-bit `Enum`. Il peut contenir jusqu'à 256 valeurs énumérées dans le `[-128, 127]` gamme.
--   16 bits `Enum`. Il peut contenir jusqu'à 65 536 valeurs énumérées dans le `[-32768, 32767]` gamme.
-
-Clickhouse choisit automatiquement le type de `Enum` lorsque les données sont insérées. Vous pouvez également utiliser `Enum8` ou `Enum16` types pour être sûr de la taille de stockage.
-
-## Exemples D'Utilisation {#usage-examples}
-
-Ici, nous créons une table avec une `Enum8('hello' = 1, 'world' = 2)` type de colonne:
-
-``` sql
-CREATE TABLE t_enum
-(
-    x Enum('hello' = 1, 'world' = 2)
-)
-ENGINE = TinyLog
-```
-
-Colonne `x` ne peut stocker que les valeurs répertoriées dans la définition de type: `'hello'` ou `'world'`. Si vous essayez d'enregistrer une autre valeur, ClickHouse déclenchera une exception. Taille 8 bits pour cela `Enum` est choisi automatiquement.
-
-``` sql
-INSERT INTO t_enum VALUES ('hello'), ('world'), ('hello')
-```
-
-``` text
-Ok.
-```
-
-``` sql
-INSERT INTO t_enum values('a')
-```
-
-``` text
-Exception on client:
-Code: 49. DB::Exception: Unknown element 'a' for type Enum('hello' = 1, 'world' = 2)
-```
-
-Lorsque vous interrogez des données de la table, ClickHouse affiche les valeurs de chaîne de `Enum`.
-
-``` sql
-SELECT * FROM t_enum
-```
-
-``` text
-┌─x─────┐
-│ hello │
-│ world │
-│ hello │
-└───────┘
-```
-
-Si vous avez besoin de voir les équivalents numériques des lignes, vous devez `Enum` valeur en type entier.
-
-``` sql
-SELECT CAST(x, 'Int8') FROM t_enum
-```
-
-``` text
-┌─CAST(x, 'Int8')─┐
-│               1 │
-│               2 │
-│               1 │
-└─────────────────┘
-```
-
-Pour créer une valeur d'Enum dans une requête, vous devez également utiliser `CAST`.
-
-``` sql
-SELECT toTypeName(CAST('a', 'Enum(\'a\' = 1, \'b\' = 2)'))
-```
-
-``` text
-┌─toTypeName(CAST('a', 'Enum(\'a\' = 1, \'b\' = 2)'))─┐
-│ Enum8('a' = 1, 'b' = 2)                             │
-└─────────────────────────────────────────────────────┘
-```
-
-## Règles générales et utilisation {#general-rules-and-usage}
-
-Chacune des valeurs se voit attribuer un nombre dans la plage `-128 ... 127` pour `Enum8` ou dans la gamme `-32768 ... 32767` pour `Enum16`. Toutes les chaînes et les nombres doivent être différents. Une chaîne vide est autorisé. Si ce type est spécifié (dans une définition de table), les nombres peuvent être dans un ordre arbitraire. Toutefois, l'ordre n'a pas d'importance.
-
-Ni la chaîne ni la valeur numérique dans un `Enum` peut être [NULL](../../sql-reference/syntax.md).
-
-Un `Enum` peut être contenue dans [Nullable](nullable.md) type. Donc, si vous créez une table en utilisant la requête
-
-``` sql
-CREATE TABLE t_enum_nullable
-(
-    x Nullable( Enum8('hello' = 1, 'world' = 2) )
-)
-ENGINE = TinyLog
-```
-
-il peut stocker non seulement des `'hello'` et `'world'`, mais `NULL`, ainsi.
-
-``` sql
-INSERT INTO t_enum_nullable Values('hello'),('world'),(NULL)
-```
-
-Dans la mémoire RAM, un `Enum` la colonne est stockée dans la même manière que `Int8` ou `Int16` des valeurs numériques correspondantes.
-
-Lors de la lecture sous forme de texte, ClickHouse analyse la valeur sous forme de chaîne et recherche la chaîne correspondante à partir de l'ensemble des valeurs Enum. Si elle n'est pas trouvée, une exception est levée. Lors de la lecture au format texte, la chaîne est lue et la valeur numérique correspondante est recherchée. Une exception sera levée si il n'est pas trouvé.
-Lors de l'écriture sous forme de texte, il écrit la valeur correspondante de la chaîne. Si les données de colonne contiennent des déchets (nombres qui ne proviennent pas de l'ensemble valide), une exception est levée. Lors de la lecture et de l'écriture sous forme binaire, cela fonctionne de la même manière que pour les types de données Int8 et Int16.
-La valeur implicite par défaut est la valeur avec le numéro le plus bas.
-
-Lors `ORDER BY`, `GROUP BY`, `IN`, `DISTINCT` et ainsi de suite, les Énumérations se comportent de la même façon que les nombres correspondants. Par exemple, ORDER BY les trie numériquement. Les opérateurs d'égalité et de comparaison fonctionnent de la même manière sur les énumérations que sur les valeurs numériques sous-jacentes.
-
-Les valeurs Enum ne peuvent pas être comparées aux nombres. Les Enums peuvent être comparés à une chaîne constante. Si la chaîne comparée à n'est pas une valeur valide pour L'énumération, une exception sera levée. L'opérateur est pris en charge avec l'Enum sur le côté gauche, et un ensemble de chaînes sur le côté droit. Les chaînes sont les valeurs de L'énumération correspondante.
-
-Most numeric and string operations are not defined for Enum values, e.g. adding a number to an Enum or concatenating a string to an Enum.
-Cependant, L'énumération a un naturel `toString` fonction qui renvoie sa valeur de chaîne.
-
-Les valeurs Enum sont également convertibles en types numériques en utilisant `toT` fonction, où T est un type numérique. Lorsque T correspond au type numérique sous-jacent de l'énumération, cette conversion est à coût nul.
-Le type Enum peut être modifié sans coût en utilisant ALTER, si seulement l'ensemble des valeurs est modifié. Il est possible d'ajouter et de supprimer des membres de L'énumération en utilisant ALTER (la suppression n'est sûre que si la valeur supprimée n'a jamais été utilisée dans la table). À titre de sauvegarde, la modification de la valeur numérique d'un membre Enum précédemment défini lancera une exception.
-
-En utilisant ALTER, il est possible de changer un Enum8 en Enum16 ou vice versa, tout comme changer un Int8 en Int16.

-toc_title: FixedString (N)
----
-
-# Fixedstring {#fixedstring}
-
-Une chaîne de longueur fixe de `N` octets (ni caractères ni points de code).
-
-Pour déclarer une colonne de `FixedString` tapez, utilisez la syntaxe suivante:
-
-``` sql
-<column_name> FixedString(N)
-```
-
-Où `N` est un nombre naturel.
-
-Le `FixedString` type est efficace lorsque les données ont la longueur de précisément `N` octet. Dans tous les autres cas, il est susceptible de réduire l'efficacité.
-
-Exemples de valeurs qui peuvent être stockées efficacement dans `FixedString`-tapé colonnes:
-
--   La représentation binaire des adresses IP (`FixedString(16)` pour IPv6).
--   Language codes (ru_RU, en_US … ).
--   Currency codes (USD, RUB … ).
--   Représentation binaire des hachages (`FixedString(16)` pour MD5, `FixedString(32)` pour SHA256).
-
-Pour stocker les valeurs UUID, utilisez [UUID](uuid.md) type de données.
-
-Lors de l'insertion des données, ClickHouse:
-
--   Complète une chaîne avec des octets null si la chaîne contient moins de `N` octet.
--   Jette le `Too large value for FixedString(N)` exception si la chaîne contient plus de `N` octet.
-
-Lors de la sélection des données, ClickHouse ne supprime pas les octets nuls à la fin de la chaîne. Si vous utilisez le `WHERE` clause, vous devez ajouter des octets null manuellement pour `FixedString` valeur. L'exemple suivant illustre l'utilisation de l' `WHERE` la clause de `FixedString`.
-
-Considérons le tableau suivant avec le seul `FixedString(2)` colonne:
-
-``` text
-┌─name──┐
-│ b     │
-└───────┘
-```
-
-Requête `SELECT * FROM FixedStringTable WHERE a = 'b'` ne renvoie aucune donnée en conséquence. Nous devrions compléter le modèle de filtre avec des octets nuls.
-
-``` sql
-SELECT * FROM FixedStringTable
-WHERE a = 'b\0'
-```
-
-``` text
-┌─a─┐
-│ b │
-└───┘
-```
-
-Ce comportement diffère de MySQL pour le `CHAR` type (où les chaînes sont remplies d'espaces et les espaces sont supprimés pour la sortie).
-
-À noter que la longueur de la `FixedString(N)` la valeur est constante. Le [longueur](../../sql-reference/functions/array-functions.md#array_functions-length) la fonction renvoie `N` même si l' `FixedString(N)` la valeur est remplie uniquement avec des octets [vide](../../sql-reference/functions/string-functions.md#empty) la fonction renvoie `1` dans ce cas.

-# Nested(name1 Type1, Name2 Type2, …) {#nestedname1-type1-name2-type2}
-
-A nested data structure is like a table inside a cell. The parameters of a nested data structure – the column names and types – are specified the same way as in a [CREATE TABLE](../../../sql-reference/statements/create.md) requête. Chaque ligne de table peut correspondre à n'importe quel nombre de lignes dans une structure de données imbriquée.
-
-Exemple:
-
-``` sql
-CREATE TABLE test.visits
-(
-    CounterID UInt32,
-    StartDate Date,
-    Sign Int8,
-    IsNew UInt8,
-    VisitID UInt64,
-    UserID UInt64,
-    ...
-    Goals Nested
-    (
-        ID UInt32,
-        Serial UInt32,
-        EventTime DateTime,
-        Price Int64,
-        OrderID String,
-        CurrencyID UInt32
-    ),
-    ...
-) ENGINE = CollapsingMergeTree(StartDate, intHash32(UserID), (CounterID, StartDate, intHash32(UserID), VisitID), 8192, Sign)
-```
-
-Cet exemple déclare le `Goals` structure de données imbriquée, qui contient des données sur les conversions (objectifs atteints). Chaque ligne de la ‘visits’ table peut correspondre à zéro ou n'importe quel nombre de conversions.
-
-Un seul niveau d'imbrication est pris en charge. Les colonnes de structures imbriquées contenant des tableaux sont équivalentes à des tableaux multidimensionnels, elles ont donc un support limité (il n'y a pas de support pour stocker ces colonnes dans des tables avec le moteur MergeTree).
-
-Dans la plupart des cas, lorsque vous travaillez avec une structure de données imbriquée, ses colonnes sont spécifiées avec des noms de colonnes séparés par un point. Ces colonnes constituent un tableau de types correspondants. Tous les tableaux de colonnes d'une structure de données imbriquée unique ont la même longueur.
-
-Exemple:
-
-``` sql
-SELECT
-    Goals.ID,
-    Goals.EventTime
-FROM test.visits
-WHERE CounterID = 101500 AND length(Goals.ID) < 5
-LIMIT 10
-```

-
-Pour une requête INSERT, vous devez passer tous les tableaux de colonnes composant d'une structure de données imbriquée séparément (comme s'il s'agissait de tableaux de colonnes individuels). Au cours de l'insertion, le système vérifie qu'ils ont la même longueur.

----
-
-# Nullable(typename) {#data_type-nullable}
-
-Permet de stocker marqueur spécial ([NULL](../../sql-reference/syntax.md)) qui dénote “missing value” aux valeurs normales autorisées par `TypeName`. Par exemple, un `Nullable(Int8)` type colonne peut stocker `Int8` type de valeurs, et les lignes qui n'ont pas de valeur magasin `NULL`.
-
-Pour un `TypeName` vous ne pouvez pas utiliser les types de données composites [Tableau](array.md) et [Tuple](tuple.md). Les types de données composites peuvent contenir `Nullable` valeurs de type, telles que `Array(Nullable(Int8))`.
-
-A `Nullable` le champ type ne peut pas être inclus dans les index de table.
-
-`NULL` est la valeur par défaut pour tout `Nullable` type, sauf indication contraire dans la configuration du serveur ClickHouse.
-
-## Caractéristiques De Stockage {#storage-features}
-
-Stocker `Nullable` valeurs de type dans une colonne de table, ClickHouse utilise un fichier séparé avec `NULL` masques en plus du fichier normal avec des valeurs. Les entrées du fichier masks permettent à ClickHouse de faire la distinction entre `NULL` et une valeur par défaut du type de données correspondant pour chaque ligne de table. En raison d'un fichier supplémentaire, `Nullable` colonne consomme de l'espace de stockage supplémentaire par rapport à une normale similaire.
-
-!!! info "Note"
-    Utiliser `Nullable` affecte presque toujours négativement les performances, gardez cela à l'esprit lors de la conception de vos bases de données.
-

-CREATE TABLE t_null(x Int8, y Nullable(Int8)) ENGINE TinyLog

-# SimpleAggregateFunction {#data-type-simpleaggregatefunction}
-
-`SimpleAggregateFunction(name, types_of_arguments…)` le type de données stocke la valeur actuelle de la fonction d'agrégat et ne stocke pas son état complet comme [`AggregateFunction`](aggregatefunction.md) faire. Cette optimisation peut être appliquée aux fonctions pour lesquelles la propriété suivante est conservée: le résultat de l'application d'une fonction `f` pour un ensemble de lignes `S1 UNION ALL S2` peut être obtenu en appliquant `f` pour les parties de la ligne définie séparément, puis à nouveau l'application `f` pour les résultats: `f(S1 UNION ALL S2) = f(f(S1) UNION ALL f(S2))`. Cette propriété garantit que les résultats d'agrégation partielle sont suffisants pour calculer le combiné, de sorte que nous n'avons pas à stocker et traiter de données supplémentaires.
-
-Les fonctions d'agrégation suivantes sont prises en charge:
-
--   [`any`](../../sql-reference/aggregate-functions/reference.md#agg_function-any)
--   [`anyLast`](../../sql-reference/aggregate-functions/reference.md#anylastx)
--   [`min`](../../sql-reference/aggregate-functions/reference.md#agg_function-min)
--   [`max`](../../sql-reference/aggregate-functions/reference.md#agg_function-max)
--   [`sum`](../../sql-reference/aggregate-functions/reference.md#agg_function-sum)
--   [`groupBitAnd`](../../sql-reference/aggregate-functions/reference.md#groupbitand)
--   [`groupBitOr`](../../sql-reference/aggregate-functions/reference.md#groupbitor)
--   [`groupBitXor`](../../sql-reference/aggregate-functions/reference.md#groupbitxor)
-
-Les valeurs de la `SimpleAggregateFunction(func, Type)` regarder et stockées de la même manière que `Type`, de sorte que vous n'avez pas besoin d'appliquer des fonctions avec `-Merge`/`-State` suffixe. `SimpleAggregateFunction` a de meilleures performances que `AggregateFunction` avec la même fonction d'agrégation.
-
-**Paramètre**
-
--   Nom de la fonction d'agrégation.
--   Types des arguments de la fonction d'agrégation.
-
-**Exemple**
-
-``` sql
-CREATE TABLE t
-(
-    column1 SimpleAggregateFunction(sum, UInt64),
-    column2 SimpleAggregateFunction(any, String)
-) ENGINE = ...

-toc_title: Intervalle
----
-
-# Intervalle {#data-type-interval}
-
-Famille de types de données représentant des intervalles d'heure et de date. Les types de la [INTERVAL](../../../sql-reference/operators/index.md#operator-interval) opérateur.
-
-!!! warning "Avertissement"
-    `Interval` les valeurs de type de données ne peuvent pas être stockées dans les tables.
-
-Structure:
-
--   Intervalle de temps en tant que valeur entière non signée.
--   Type de l'intervalle.
-
-Types d'intervalles pris en charge:
-
--   `SECOND`
--   `MINUTE`
--   `HOUR`
--   `DAY`
--   `WEEK`
--   `MONTH`
--   `QUARTER`
--   `YEAR`
-
-Pour chaque type d'intervalle, il existe un type de données distinct. Par exemple, l' `DAY` l'intervalle correspond au `IntervalDay` type de données:
-
-``` sql
-SELECT toTypeName(INTERVAL 4 DAY)
-```
-
-``` text
-┌─toTypeName(toIntervalDay(4))─┐
-│ IntervalDay                  │
-└──────────────────────────────┘
-```
-
-## Utilisation Remarques {#data-type-interval-usage-remarks}
-
-Vous pouvez utiliser `Interval`-tapez des valeurs dans des opérations arithmétiques avec [Date](../../../sql-reference/data-types/date.md) et [DateTime](../../../sql-reference/data-types/datetime.md)-type de valeurs. Par exemple, vous pouvez ajouter 4 jours à l'heure actuelle:
-
-``` sql
-SELECT now() as current_date_time, current_date_time + INTERVAL 4 DAY
-```
-
-``` text
-┌───current_date_time─┬─plus(now(), toIntervalDay(4))─┐
-│ 2019-10-23 10:58:45 │           2019-10-27 10:58:45 │
-└─────────────────────┴───────────────────────────────┘
-```
-
-Les intervalles avec différents types ne peuvent pas être combinés. Vous ne pouvez pas utiliser des intervalles comme `4 DAY 1 HOUR`. Spécifiez des intervalles en unités inférieures ou égales à la plus petite unité de l'intervalle, par exemple, l'intervalle `1 day and an hour` l'intervalle peut être exprimée comme `25 HOUR` ou `90000 SECOND`.
-
-Vous ne pouvez pas effectuer d'opérations arithmétiques avec `Interval`- tapez des valeurs, mais vous pouvez ajouter des intervalles de différents types par conséquent aux valeurs dans `Date` ou `DateTime` types de données. Exemple:
-
-``` sql
-SELECT now() AS current_date_time, current_date_time + INTERVAL 4 DAY + INTERVAL 3 HOUR
-```
-
-``` text
-┌───current_date_time─┬─plus(plus(now(), toIntervalDay(4)), toIntervalHour(3))─┐
-│ 2019-10-23 11:16:28 │                                    2019-10-27 14:16:28 │
-└─────────────────────┴────────────────────────────────────────────────────────┘
-```
-
-La requête suivante provoque une exception:
-
-``` sql
-select now() AS current_date_time, current_date_time + (INTERVAL 4 DAY + INTERVAL 3 HOUR)
-```
-
-``` text
-Received exception from server (version 19.14.1):
-Code: 43. DB::Exception: Received from localhost:9000. DB::Exception: Wrong argument types for function plus: if one argument is Interval, then another must be Date or DateTime..

-
-## Encodage {#encodings}
-
-ClickHouse n'a pas le concept d'encodages. Les chaînes peuvent contenir un ensemble arbitraire d'octets, qui sont stockés et sortis tels quels.
-Si vous avez besoin de stocker des textes, nous vous recommandons d'utiliser L'encodage UTF-8. À tout le moins, si votre terminal utilise UTF-8 (comme recommandé), vous pouvez lire et écrire vos valeurs sans effectuer de conversions.
-De même, certaines fonctions pour travailler avec des chaînes ont des variations distinctes qui fonctionnent sous l'hypothèse que la chaîne contient un ensemble d'octets représentant un texte codé en UTF-8.
-Par exemple, l' ‘length’ fonction calcule la longueur de la chaîne en octets, tandis que le ‘lengthUTF8’ la fonction calcule la longueur de la chaîne en points de code Unicode, en supposant que la valeur est encodée en UTF-8.

-# Tuple(t1, T2, …) {#tuplet1-t2}
-
-Un n-uplet d'éléments, chacun ayant une personne [type](index.md#data_types).
-
-Les Tuples sont utilisés pour le regroupement temporaire de colonnes. Les colonnes peuvent être regroupées lorsqu'une expression IN est utilisée dans une requête et pour spécifier certains paramètres formels des fonctions lambda. Pour plus d'informations, voir les sections [Dans les opérateurs](../../sql-reference/operators/in.md) et [Des fonctions d'ordre supérieur](../../sql-reference/functions/higher-order-functions.md).
-
-Les Tuples peuvent être le résultat d'une requête. Dans ce cas, pour les formats de texte autres que JSON, les valeurs sont séparées par des virgules entre parenthèses. Dans les formats JSON, les tuples sont sortis sous forme de tableaux (entre crochets).
-
-## La création d'un Tuple {#creating-a-tuple}
-
-Vous pouvez utiliser une fonction pour créer un tuple:
-
-``` sql
-tuple(T1, T2, ...)
-```
-
-Exemple de création d'un tuple:
-
-``` sql
-SELECT tuple(1,'a') AS x, toTypeName(x)
-```
-
-``` text
-┌─x───────┬─toTypeName(tuple(1, 'a'))─┐

-
-## Utilisation de Types de données {#working-with-data-types}

-Lors de la création d'un tuple à la volée, ClickHouse détecte automatiquement le type de chaque argument comme le minimum des types qui peuvent stocker la valeur de l'argument. Si l'argument est [NULL](../../sql-reference/syntax.md#null-literal) le type de l'élément tuple est [Nullable](nullable.md).
-
-Exemple de détection automatique de type de données:
-
-``` sql
-SELECT tuple(1, NULL) AS x, toTypeName(x)
-```
-
-``` text

-## Comment générer {#how-to-generate}
-
-Pour générer la valeur UUID, ClickHouse fournit [generateUUIDv4](../../sql-reference/functions/uuid-functions.md) fonction.
-
-## Exemple D'Utilisation {#usage-example}
-
-**Exemple 1**
-
-Cet exemple montre la création d'une table avec la colonne de type UUID et l'insertion d'une valeur dans la table.
-
-``` sql
-CREATE TABLE t_uuid (x UUID, y String) ENGINE=TinyLog
-```
-
-``` sql
-INSERT INTO t_uuid SELECT generateUUIDv4(), 'Example 1'
-```
-
-``` sql
-SELECT * FROM t_uuid
-```
-
-``` text
-┌────────────────────────────────────x─┬─y─────────┐
-│ 417ddc5d-e556-4d27-95dd-a34d84e46a50 │ Example 1 │
-└──────────────────────────────────────┴───────────┘
-```
-
-**Exemple 2**
-
-Dans cet exemple, la valeur de la colonne UUID n'est pas spécifiée lors de l'insertion d'un nouvel enregistrement.
-
-``` sql
-INSERT INTO t_uuid (y) VALUES ('Example 2')
-```
-
-``` sql
-SELECT * FROM t_uuid
-```
-
-``` text
-┌────────────────────────────────────x─┬─y─────────┐
-│ 417ddc5d-e556-4d27-95dd-a34d84e46a50 │ Example 1 │
-│ 00000000-0000-0000-0000-000000000000 │ Example 2 │
-└──────────────────────────────────────┴───────────┘
-```
-
-## Restriction {#restrictions}
-
-Le type de données UUID ne prend en charge que les fonctions qui [Chaîne](string.md) type de données prend également en charge (par exemple, [min](../../sql-reference/aggregate-functions/reference.md#agg_function-min), [Max](../../sql-reference/aggregate-functions/reference.md#agg_function-max), et [compter](../../sql-reference/aggregate-functions/reference.md#agg_function-count)).
-
-Le type de données UUID n'est pas pris en charge par les opérations arithmétiques (par exemple, [ABS](../../sql-reference/functions/arithmetic-functions.md#arithm_func-abs)) ou des fonctions d'agrégation, comme [somme](../../sql-reference/aggregate-functions/reference.md#agg_function-sum) et [avg](../../sql-reference/aggregate-functions/reference.md#agg_function-avg).

-# Dictionnaires Hiérarchiques {#hierarchical-dictionaries}
-
-Clickhouse prend en charge les dictionnaires hiérarchiques avec un [touche numérique](external-dicts-dict-structure.md#ext_dict-numeric-key).
-
-Voici une structure hiérarchique:
-
-``` text
-0 (Common parent)
-│
-├── 1 (Russia)
-│   │
-│   └── 2 (Moscow)
-│       │
-│       └── 3 (Center)
-│
-└── 4 (Great Britain)
-    │
-    └── 5 (London)
-```
-
-Cette hiérarchie peut être exprimée comme la table de dictionnaire suivante.
-
-| id_région | région_parent | nom_région        |
-|------------|----------------|--------------------|
-| 1          | 0              | Russie             |
-| 2          | 1              | Moscou             |
-| 3          | 2              | Center             |
-| 4          | 0              | La Grande-Bretagne |
-| 5          | 4              | Londres            |
-
-Ce tableau contient une colonne `parent_region` qui contient la clé du parent le plus proche de l'élément.
-
-Clickhouse soutient le [hiérarchique](external-dicts-dict-structure.md#hierarchical-dict-attr) propriété pour [externe dictionnaire](index.md) attribut. Cette propriété vous permet de configurer le dictionnaire hiérarchique comme décrit ci-dessus.
-
-Le [dictGetHierarchy](../../../sql-reference/functions/ext-dict-functions.md#dictgethierarchy) la fonction vous permet d'obtenir la chaîne parent d'un élément.
-
-Pour notre exemple, la structure du dictionnaire peut être la suivante:
-
-``` xml
-<dictionary>
-    <structure>
-        <id>
-            <name>region_id</name>
-        </id>
-
-        <attribute>
-            <name>parent_region</name>
-            <type>UInt64</type>
-            <null_value>0</null_value>
-            <hierarchical>true</hierarchical>
-        </attribute>
-
-        <attribute>
-            <name>region_name</name>
-            <type>String</type>
-            <null_value></null_value>
-        </attribute>
-
-    </structure>
-</dictionary>
-```

-# Stockage des dictionnaires en mémoire {#dicts-external-dicts-dict-layout}
-
-Il existe une variété de façons de stocker les dictionnaires en mémoire.
-
-Nous vous recommandons [plat](#flat), [haché](#dicts-external_dicts_dict_layout-hashed) et [complex_key_hashed](#complex-key-hashed). qui fournissent la vitesse de traitement optimale.
-
-La mise en cache n'est pas recommandée en raison de performances potentiellement médiocres et de difficultés à sélectionner les paramètres optimaux. En savoir plus dans la section “[cache](#cache)”.
-
-Il existe plusieurs façons d'améliorer les performances du dictionnaire:
-
--   Appelez la fonction pour travailler avec le dictionnaire après `GROUP BY`.
--   Marquer les attributs à extraire comme injectifs. Un attribut est appelé injectif si différentes valeurs d'attribut correspondent à différentes clés. Alors, quand `GROUP BY` utilise une fonction qui récupère une valeur d'attribut par la clé, cette fonction est automatiquement retirée de `GROUP BY`.
-
-ClickHouse génère une exception pour les erreurs avec les dictionnaires. Des exemples d'erreurs:
-
--   Le dictionnaire accessible n'a pas pu être chargé.
--   Erreur de la requête d'une `cached` dictionnaire.
-
-Vous pouvez afficher la liste des dictionnaires externes et leurs statuts dans le `system.dictionaries` table.
-
-La configuration ressemble à ceci:
-
-``` xml
-<yandex>
-    <dictionary>
-        ...
-        <layout>
-            <layout_type>
-                <!-- layout settings -->
-            </layout_type>
-        </layout>
-        ...
-    </dictionary>
-</yandex>
-```
-
-Correspondant [DDL-requête](../../statements/create.md#create-dictionary-query):
-
-``` sql
-CREATE DICTIONARY (...)
-...
-LAYOUT(LAYOUT_TYPE(param value)) -- layout settings
-...
-```
-
-## Façons de stocker des dictionnaires en mémoire {#ways-to-store-dictionaries-in-memory}
-
--   [plat](#flat)
--   [haché](#dicts-external_dicts_dict_layout-hashed)
--   [sparse_hashed](#dicts-external_dicts_dict_layout-sparse_hashed)
--   [cache](#cache)
--   [direct](#direct)
--   [range_hashed](#range-hashed)
--   [complex_key_hashed](#complex-key-hashed)
--   [complex_key_cache](#complex-key-cache)
--   [complex_key_direct](#complex-key-direct)
--   [ip_trie](#ip-trie)
-
-### plat {#flat}
-
-Le dictionnaire est complètement stocké en mémoire sous la forme de tableaux plats. Combien de mémoire le dictionnaire utilise-t-il? Le montant est proportionnel à la taille de la plus grande clé (dans l'espace).
-
-La clé du dictionnaire a le `UInt64` type et la valeur est limitée à 500 000. Si une clé plus grande est découverte lors de la création du dictionnaire, ClickHouse lève une exception et ne crée pas le dictionnaire.
-
-Tous les types de sources sont pris en charge. Lors de la mise à jour, les données (à partir d'un fichier ou d'une table) sont lues dans leur intégralité.
-
-Cette méthode fournit les meilleures performances parmi toutes les méthodes disponibles de stockage du dictionnaire.
-
-Exemple de Configuration:
-
-``` xml
-<layout>
-  <flat />
-</layout>
-```
-
-ou
-
-``` sql
-LAYOUT(FLAT())
-```
-
-### haché {#dicts-external_dicts_dict_layout-hashed}
-
-Le dictionnaire est entièrement stockée en mémoire sous la forme d'une table de hachage. Le dictionnaire peut contenir n'importe quel nombre d'éléments avec tous les identificateurs Dans la pratique, le nombre de clés peut atteindre des dizaines de millions d'articles.
-
-Tous les types de sources sont pris en charge. Lors de la mise à jour, les données (à partir d'un fichier ou d'une table) sont lues dans leur intégralité.
-
-Exemple de Configuration:
-
-``` xml
-<layout>
-  <hashed />
-</layout>
-```
-
-ou
-
-``` sql
-LAYOUT(HASHED())
-```
-
-### sparse_hashed {#dicts-external_dicts_dict_layout-sparse_hashed}
-
-Semblable à `hashed`, mais utilise moins de mémoire en faveur de plus D'utilisation du processeur.
-
-Exemple de Configuration:
-
-``` xml
-<layout>
-  <sparse_hashed />
-</layout>
-```
-
-``` sql
-LAYOUT(SPARSE_HASHED())
-```
-
-### complex_key_hashed {#complex-key-hashed}
-
-Ce type de stockage est pour une utilisation avec composite [touches](external-dicts-dict-structure.md). Semblable à `hashed`.
-
-Exemple de Configuration:
-
-``` xml
-<layout>
-  <complex_key_hashed />
-</layout>
-```
-
-``` sql
-LAYOUT(COMPLEX_KEY_HASHED())
-```
-
-### range_hashed {#range-hashed}
-
-Le dictionnaire est stocké en mémoire sous la forme d'une table de hachage avec un tableau ordonné de gammes et leurs valeurs correspondantes.
-
-Cette méthode de stockage fonctionne de la même manière que hachée et permet d'utiliser des plages de date / heure (Type numérique arbitraire) en plus de la clé.
-
-Exemple: Le tableau contient des réductions pour chaque annonceur dans le format:
-
-``` text
-+---------|-------------|-------------|------+
-| advertiser id | discount start date | discount end date | amount |
-+===============+=====================+===================+========+
-| 123           | 2015-01-01          | 2015-01-15        | 0.15   |
-+---------|-------------|-------------|------+
-| 123           | 2015-01-16          | 2015-01-31        | 0.25   |
-+---------|-------------|-------------|------+
-| 456           | 2015-01-01          | 2015-01-15        | 0.05   |
-+---------|-------------|-------------|------+
-```
-
-Pour utiliser un échantillon pour les plages de dates, définissez `range_min` et `range_max` éléments dans le [structure](external-dicts-dict-structure.md). Ces éléments doivent contenir des éléments `name` et`type` (si `type` n'est pas spécifié, le type par défaut sera utilisé-Date). `type` peut être n'importe quel type numérique (Date / DateTime / UInt64 / Int32 / autres).
-
-Exemple:
-
-``` xml
-<structure>
-    <id>
-        <name>Id</name>
-    </id>
-    <range_min>
-        <name>first</name>
-        <type>Date</type>
-    </range_min>
-    <range_max>
-        <name>last</name>
-        <type>Date</type>
-    </range_max>
-    ...
-```
-
-ou
-
-``` sql
-CREATE DICTIONARY somedict (
-    id UInt64,
-    first Date,
-    last Date
-)
-PRIMARY KEY id
-LAYOUT(RANGE_HASHED())
-RANGE(MIN first MAX last)
-```
-
-Pour travailler avec ces dictionnaires, vous devez passer un argument supplémentaire à l' `dictGetT` fonction, pour laquelle une plage est sélectionnée:
-
-``` sql
-dictGetT('dict_name', 'attr_name', id, date)
-```
-
-Cette fonction retourne la valeur pour l' `id`s et la plage de dates qui inclut la date passée.
-
-Détails de l'algorithme:
-
--   Si l' `id` est introuvable ou une plage n'est pas trouvé pour l' `id` il retourne la valeur par défaut pour le dictionnaire.
--   S'il y a des plages qui se chevauchent, vous pouvez en utiliser.
--   Si le délimiteur est `NULL` ou une date non valide (telle que 1900-01-01 ou 2039-01-01), la plage est laissée ouverte. La gamme peut être ouverte des deux côtés.
-
-Exemple de Configuration:
-
-``` xml
-<yandex>
-        <dictionary>
-
-                ...
-
-                <layout>
-                        <range_hashed />

-    StartTimeStamp UInt64,
-    EndTimeStamp UInt64,

-PRIMARY KEY Abcdef
-RANGE(MIN StartTimeStamp MAX EndTimeStamp)
-```
-
-### cache {#cache}
-
-Le dictionnaire est stocké dans un cache qui a un nombre fixe de cellules. Ces cellules contiennent des éléments fréquemment utilisés.
-
-Lors de la recherche d'un dictionnaire, le cache est recherché en premier. Pour chaque bloc de données, toutes les clés qui ne sont pas trouvées dans le cache ou qui sont obsolètes sont demandées à la source en utilisant `SELECT attrs... FROM db.table WHERE id IN (k1, k2, ...)`. Les données reçues sont ensuite écrites dans le cache.
-
-Pour les dictionnaires de cache, l'expiration [vie](external-dicts-dict-lifetime.md) des données dans le cache peuvent être définies. Si plus de temps que `lifetime` passé depuis le chargement des données dans une cellule, la valeur de la cellule n'est pas utilisée et elle est demandée à nouveau la prochaine fois qu'elle doit être utilisée.
-C'est la moins efficace de toutes les façons de stocker les dictionnaires. La vitesse du cache dépend fortement des paramètres corrects et que le scénario d'utilisation. Un dictionnaire de type de cache fonctionne bien uniquement lorsque les taux de réussite sont suffisamment élevés (recommandé 99% et plus). Vous pouvez afficher le taux de réussite moyen dans le `system.dictionaries` table.
-
-Pour améliorer les performances du cache, utilisez une sous-requête avec `LIMIT`, et appelez la fonction avec le dictionnaire en externe.
-
-Soutenu [source](external-dicts-dict-sources.md): MySQL, ClickHouse, exécutable, HTTP.
-
-Exemple de paramètres:
-
-``` xml
-<layout>
-    <cache>
-        <!-- The size of the cache, in number of cells. Rounded up to a power of two. -->
-        <size_in_cells>1000000000</size_in_cells>
-    </cache>
-</layout>
-```
-
-ou
-
-``` sql
-LAYOUT(CACHE(SIZE_IN_CELLS 1000000000))
-```
-
-Définissez une taille de cache suffisamment grande. Vous devez expérimenter pour sélectionner le nombre de cellules:
-
-1.  Définissez une valeur.
-2.  Exécutez les requêtes jusqu'à ce que le cache soit complètement plein.
-3.  Évaluer la consommation de mémoire en utilisant le `system.dictionaries` table.
-4.  Augmentez ou diminuez le nombre de cellules jusqu'à ce que la consommation de mémoire requise soit atteinte.
-
-!!! warning "Avertissement"
-    N'utilisez pas ClickHouse comme source, car le traitement des requêtes avec des lectures aléatoires est lent.
-
-### complex_key_cache {#complex-key-cache}
-
-Ce type de stockage est pour une utilisation avec composite [touches](external-dicts-dict-structure.md). Semblable à `cache`.
-
-### direct {#direct}
-
-Le dictionnaire n'est pas stocké dans la mémoire et va directement à la source, pendant le traitement d'une demande.
-
-La clé du dictionnaire a le `UInt64` type.
-
-Tous les types de [source](external-dicts-dict-sources.md), sauf les fichiers locaux, sont pris en charge.
-
-Exemple de Configuration:
-
-``` xml
-<layout>
-  <direct />
-</layout>
-```
-
-ou
-
-``` sql
-LAYOUT(DIRECT())
-```
-
-### complex_key_direct {#complex-key-direct}
-
-Ce type de stockage est destiné à être utilisé avec des [clés](../../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-structure.md) composites. Similaire à `direct`
-
-### ip_trie {#ip-trie}
-
-Ce type de stockage permet de mapper des préfixes de réseau (adresses IP) à des métadonnées telles que ASN.
-
-Exemple: la table contient les préfixes de réseau et leur correspondant en tant que numéro et Code de pays:
-
-``` text
-  +-----------|-----|------+
-  | prefix          | asn   | cca2   |
-  +=================+=======+========+
-  | 202.79.32.0/20  | 17501 | NP     |
-  +-----------|-----|------+
-  | 2620:0:870::/48 | 3856  | US     |
-  +-----------|-----|------+
-  | 2a02:6b8:1::/48 | 13238 | RU     |
-  +-----------|-----|------+
-  | 2001:db8::/32   | 65536 | ZZ     |
-  +-----------|-----|------+
-```
-
-Lorsque vous utilisez ce type de mise en page, la structure doit avoir une clé composite.
-
-Exemple:
-
-``` xml
-<structure>
-    <key>
-        <attribute>
-            <name>prefix</name>
-            <type>String</type>
-        </attribute>
-    </key>
-    <attribute>
-            <name>asn</name>
-            <type>UInt32</type>
-            <null_value />
-    </attribute>
-    <attribute>
-            <name>cca2</name>
-            <type>String</type>
-            <null_value>??</null_value>
-    </attribute>
-    ...
-</structure>
-<layout>
-    <ip_trie>
-        <access_to_key_from_attributes>true</access_to_key_from_attributes>
-    </ip_trie>
-</layout>
-```
-
-ou
-
-``` sql
-CREATE DICTIONARY somedict (
-    prefix String,
-    asn UInt32,
-    cca2 String DEFAULT '??'
-)
-PRIMARY KEY prefix
-```
-
-La clé ne doit avoir qu'un seul attribut de type chaîne contenant un préfixe IP autorisé. Les autres types ne sont pas encore pris en charge.
-
-Pour les requêtes, vous devez utiliser les mêmes fonctions (`dictGetT` avec un n-uplet) comme pour les dictionnaires avec des clés composites:
-
-``` sql
-dictGetT('dict_name', 'attr_name', tuple(ip))
-```
-
-La fonction prend soit `UInt32` pour IPv4, ou `FixedString(16)` pour IPv6:
-
-``` sql
-dictGetString('prefix', 'asn', tuple(IPv6StringToNum('2001:db8::1')))
-```
-
-Les autres types ne sont pas encore pris en charge. La fonction renvoie l'attribut du préfixe correspondant à cette adresse IP. S'il y a chevauchement des préfixes, le plus spécifique est retourné.
-
-Les données doit complètement s'intégrer dans la RAM.

-# Mises À Jour Du Dictionnaire {#dictionary-updates}
-
-ClickHouse met périodiquement à jour les dictionnaires. L'intervalle de mise à jour pour les dictionnaires entièrement téléchargés et l'intervalle d'invalidation pour les dictionnaires `<lifetime>` tag en quelques secondes.
-
-Les mises à jour du dictionnaire (autres que le chargement pour la première utilisation) ne bloquent pas les requêtes. Lors des mises à jour, l'ancienne version d'un dictionnaire est utilisée. Si une erreur se produit pendant une mise à jour, l'erreur est écrite dans le journal du serveur et les requêtes continuent d'utiliser l'ancienne version des dictionnaires.
-
-Exemple de paramètres:
-
-``` xml
-<dictionary>
-    ...
-    <lifetime>300</lifetime>
-    ...
-</dictionary>
-```
-
-``` sql
-CREATE DICTIONARY (...)
-...
-LIFETIME(300)
-...
-```
-
-Paramètre `<lifetime>0</lifetime>` (`LIFETIME(0)`) empêche la mise à jour des dictionnaires.
-
-Vous pouvez définir un intervalle de temps pour les mises à niveau, et ClickHouse choisira un temps uniformément aléatoire dans cette plage. Ceci est nécessaire pour répartir la charge sur la source du dictionnaire lors de la mise à niveau sur un grand nombre de serveurs.
-
-Exemple de paramètres:
-
-``` xml
-<dictionary>
-    ...
-    <lifetime>
-        <min>300</min>
-        <max>360</max>
-    </lifetime>
-    ...
-</dictionary>
-```
-
-ou
-
-``` sql
-LIFETIME(MIN 300 MAX 360)
-```
-
-Si `<min>0</min>` et `<max>0</max>`, ClickHouse ne recharge pas le dictionnaire par timeout.
-Dans ce cas, ClickHouse peut recharger le dictionnaire plus tôt si le fichier de configuration du dictionnaire a été `SYSTEM RELOAD DICTIONARY` la commande a été exécutée.
-
-Lors de la mise à niveau des dictionnaires, le serveur ClickHouse applique une logique différente selon le type de [source](external-dicts-dict-sources.md):
-
-Lors de la mise à niveau des dictionnaires, le serveur ClickHouse applique une logique différente selon le type de [source](external-dicts-dict-sources.md):
-
--   Pour un fichier texte, il vérifie l'heure de la modification. Si l'heure diffère de l'heure enregistrée précédemment, le dictionnaire est mis à jour.
--   Pour les tables MyISAM, l'Heure de modification est vérifiée à l'aide d'un `SHOW TABLE STATUS` requête.
--   Les dictionnaires d'autres sources sont mis à jour à chaque fois par défaut.
-
-Pour les sources MySQL (InnoDB), ODBC et ClickHouse, vous pouvez configurer une requête qui mettra à jour les dictionnaires uniquement s'ils ont vraiment changé, plutôt que chaque fois. Pour ce faire, suivez ces étapes:
-
--   La table de dictionnaire doit avoir un champ qui change toujours lorsque les données source sont mises à jour.
--   Les paramètres de la source doivent spécifier une requête qui récupère le champ de modification. Le serveur ClickHouse interprète le résultat de la requête comme une ligne, et si cette ligne a changé par rapport à son état précédent, le dictionnaire est mis à jour. Spécifier la requête dans le `<invalidate_query>` champ dans les paramètres pour le [source](external-dicts-dict-sources.md).
-
-Exemple de paramètres:
-
-``` xml
-<dictionary>
-    ...
-    <odbc>
-      ...
-      <invalidate_query>SELECT update_time FROM dictionary_source where id = 1</invalidate_query>
-    </odbc>
-    ...
-</dictionary>
-```
-
-ou
-
-``` sql
-...
-SOURCE(ODBC(... invalidate_query 'SELECT update_time FROM dictionary_source where id = 1'))

----
-
-# Sources de dictionnaires externes {#dicts-external-dicts-dict-sources}
-
-Externe dictionnaire peut être connecté à partir de nombreuses sources différentes.
-
-Si dictionary est configuré à l'aide de xml-file, la configuration ressemble à ceci:
-
-``` xml
-<yandex>
-  <dictionary>
-    ...
-    <source>
-      <source_type>
-        <!-- Source configuration -->
-      </source_type>
-    </source>
-    ...
-  </dictionary>
-  ...
-</yandex>
-```
-
-En cas de [DDL-requête](../../statements/create.md#create-dictionary-query), configuration égale ressemblera à:
-
-``` sql
-CREATE DICTIONARY dict_name (...)
-...
-SOURCE(SOURCE_TYPE(param1 val1 ... paramN valN)) -- Source configuration
-...
-```
-
-La source est configurée dans le `source` section.
-
-Pour les types de source [Fichier Local](#dicts-external_dicts_dict_sources-local_file), [Fichier exécutable](#dicts-external_dicts_dict_sources-executable), [HTTP(S)](#dicts-external_dicts_dict_sources-http), [ClickHouse](#dicts-external_dicts_dict_sources-clickhouse)
-les paramètres optionnels sont disponibles:
-
-``` xml
-<source>
-  <file>
-    <path>/opt/dictionaries/os.tsv</path>
-    <format>TabSeparated</format>
-  </file>
-  <settings>
-      <format_csv_allow_single_quotes>0</format_csv_allow_single_quotes>
-  </settings>
-</source>
-```
-
-ou
-
-``` sql
-SOURCE(FILE(path '/opt/dictionaries/os.tsv' format 'TabSeparated'))
-SETTINGS(format_csv_allow_single_quotes = 0)

-## Fichier Local {#dicts-external_dicts_dict_sources-local_file}
-
-Exemple de paramètres:
-
-``` xml
-<source>
-  <file>
-    <path>/opt/dictionaries/os.tsv</path>
-    <format>TabSeparated</format>
-  </file>
-</source>
-```
-
-ou
-
-``` sql
-SOURCE(FILE(path '/opt/dictionaries/os.tsv' format 'TabSeparated'))
-```
-
-Définition des champs:
-
--   `path` – The absolute path to the file.
--   `format` – The file format. All the formats described in “[Format](../../../interfaces/formats.md#formats)” sont pris en charge.
-
-## Fichier Exécutable {#dicts-external_dicts_dict_sources-executable}
-
-Travailler avec des fichiers exécutables en dépend [comment le dictionnaire est stocké dans la mémoire](external-dicts-dict-layout.md). Si le dictionnaire est stocké en utilisant `cache` et `complex_key_cache`, Clickhouse demande les clés nécessaires en envoyant une requête au STDIN du fichier exécutable. Sinon, ClickHouse démarre le fichier exécutable et traite sa sortie comme des données de dictionnaire.
-
-Exemple de paramètres:
-
-``` xml
-<source>
-    <executable>
-        <command>cat /opt/dictionaries/os.tsv</command>
-        <format>TabSeparated</format>
-    </executable>
-</source>
-```
-
-ou
-
-``` sql
-SOURCE(EXECUTABLE(command 'cat /opt/dictionaries/os.tsv' format 'TabSeparated'))
-```
-
-Définition des champs:
-
--   `command` – The absolute path to the executable file, or the file name (if the program directory is written to `PATH`).
--   `format` – The file format. All the formats described in “[Format](../../../interfaces/formats.md#formats)” sont pris en charge.
-
-## Http(s) {#dicts-external_dicts_dict_sources-http}
-
-Travailler avec un serveur HTTP (S) dépend de [comment le dictionnaire est stocké dans la mémoire](external-dicts-dict-layout.md). Si le dictionnaire est stocké en utilisant `cache` et `complex_key_cache`, Clickhouse demande les clés nécessaires en envoyant une demande via le `POST` méthode.
-
-Exemple de paramètres:
-
-``` xml
-<source>
-    <http>
-        <url>http://[::1]/os.tsv</url>
-        <format>TabSeparated</format>
-        <credentials>
-            <user>user</user>
-            <password>password</password>
-        </credentials>
-        <headers>
-            <header>
-                <name>API-KEY</name>
-                <value>key</value>
-            </header>
-        </headers>
-    </http>
-</source>
-```
-
-ou
-
-``` sql
-SOURCE(HTTP(
-    url 'http://[::1]/os.tsv'
-    format 'TabSeparated'
-    credentials(user 'user' password 'password')
-    headers(header(name 'API-KEY' value 'key'))
-))
-```
-
-Pour que ClickHouse accède à une ressource HTTPS, vous devez [configurer openSSL](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-openssl) dans la configuration du serveur.
-
-Définition des champs:
-
--   `url` – The source URL.
--   `format` – The file format. All the formats described in “[Format](../../../interfaces/formats.md#formats)” sont pris en charge.
--   `credentials` – Basic HTTP authentication. Optional parameter.
-    -   `user` – Username required for the authentication.
-    -   `password` – Password required for the authentication.
--   `headers` – All custom HTTP headers entries used for the HTTP request. Optional parameter.
-    -   `header` – Single HTTP header entry.
-    -   `name` – Identifiant name used for the header send on the request.
-    -   `value` – Value set for a specific identifiant name.
-
-## ODBC {#dicts-external_dicts_dict_sources-odbc}
-
-Vous pouvez utiliser cette méthode pour connecter n'importe quelle base de données dotée d'un pilote ODBC.
-
-Exemple de paramètres:
-
-``` xml
-<source>
-    <odbc>
-        <db>DatabaseName</db>
-        <table>ShemaName.TableName</table>
-        <connection_string>DSN=some_parameters</connection_string>
-        <invalidate_query>SQL_QUERY</invalidate_query>
-    </odbc>
-</source>
-```
-
-ou
-
-``` sql
-SOURCE(ODBC(
-    db 'DatabaseName'
-    table 'SchemaName.TableName'
-    connection_string 'DSN=some_parameters'
-    invalidate_query 'SQL_QUERY'
-))
-```
-
-Définition des champs:
-
--   `db` – Name of the database. Omit it if the database name is set in the `<connection_string>` paramètre.
--   `table` – Name of the table and schema if exists.
--   `connection_string` – Connection string.
--   `invalidate_query` – Query for checking the dictionary status. Optional parameter. Read more in the section [Mise à jour des dictionnaires](external-dicts-dict-lifetime.md).
-
-ClickHouse reçoit des symboles de citation D'ODBC-driver et cite tous les paramètres des requêtes au pilote, il est donc nécessaire de définir le nom de la table en conséquence sur le cas du nom de la table dans la base de données.

-Si vous avez des problèmes avec des encodages lors de l'utilisation d'Oracle, consultez le [FAQ](../../../faq/general.md#oracle-odbc-encodings) article.
-
-### Vulnérabilité connue de la fonctionnalité du dictionnaire ODBC {#known-vulnerability-of-the-odbc-dictionary-functionality}
-
-!!! attention "Attention"
-    Lors de la connexion à la base de données via le paramètre de connexion du pilote ODBC `Servername` peut être substitué. Dans ce cas, les valeurs de `USERNAME` et `PASSWORD` de `odbc.ini` sont envoyés au serveur distant et peuvent être compromis.
-
-**Exemple d'utilisation non sécurisée**
-
-Configurons unixODBC pour PostgreSQL. Le contenu de `/etc/odbc.ini`:
-
-``` text
-[gregtest]
-Driver = /usr/lib/psqlodbca.so
-Servername = localhost
-PORT = 5432
-DATABASE = test_db
-#OPTION = 3
-USERNAME = test
-PASSWORD = test
-```
-
-Si vous faites alors une requête telle que
-
-``` sql
-SELECT * FROM odbc('DSN=gregtest;Servername=some-server.com', 'test_db');
-```
-
-Le pilote ODBC enverra des valeurs de `USERNAME` et `PASSWORD` de `odbc.ini` de `some-server.com`.
-
-### Exemple de connexion Postgresql {#example-of-connecting-postgresql}
-
-Ubuntu OS.
-
-Installation d'unixODBC et du pilote ODBC pour PostgreSQL:
-
-``` bash
-$ sudo apt-get install -y unixodbc odbcinst odbc-postgresql
-```
-
-Configuration `/etc/odbc.ini` (ou `~/.odbc.ini`):
-
-``` text
-    [DEFAULT]
-    Driver = myconnection
-

----
-
-# Clé et champs du dictionnaire {#dictionary-key-and-fields}
-
-Le `<structure>` la clause décrit la clé du dictionnaire et les champs disponibles pour les requêtes.
-
-Description XML:
-
-``` xml
-<dictionary>
-    <structure>
-        <id>
-            <name>Id</name>
-        </id>
-
-        <attribute>
-            <!-- Attribute parameters -->
-        </attribute>
-
-        ...
-
-    </structure>
-</dictionary>
-```
-
-Les attributs sont décrits dans les éléments:
-
--   `<id>` — [La colonne de la clé](external-dicts-dict-structure.md#ext_dict_structure-key).
--   `<attribute>` — [Colonne de données](external-dicts-dict-structure.md#ext_dict_structure-attributes). Il peut y avoir un certain nombre d'attributs.
-
-Requête DDL:
-
-``` sql
-CREATE DICTIONARY dict_name (
-    Id UInt64,
-    -- attributes
-)
-PRIMARY KEY Id
-...
-```
-
-Les attributs sont décrits dans le corps de la requête:
-
--   `PRIMARY KEY` — [La colonne de la clé](external-dicts-dict-structure.md#ext_dict_structure-key)
--   `AttrName AttrType` — [Colonne de données](external-dicts-dict-structure.md#ext_dict_structure-attributes). Il peut y avoir un certain nombre d'attributs.
-
-## Clé {#ext_dict_structure-key}
-
-ClickHouse prend en charge les types de clés suivants:
-
--   Touche numérique. `UInt64`. Défini dans le `<id>` tag ou en utilisant `PRIMARY KEY` mot.
--   Clé Composite. Ensemble de valeurs de types différents. Défini dans la balise `<key>` ou `PRIMARY KEY` mot.
-
-Une structure xml peut contenir `<id>` ou `<key>`. DDL-requête doit contenir unique `PRIMARY KEY`.
-
-!!! warning "Avertissement"
-    Vous ne devez pas décrire clé comme un attribut.
-
-### Touche Numérique {#ext_dict-numeric-key}
-
-Type: `UInt64`.
-
-Exemple de Configuration:
-
-``` xml
-<id>
-    <name>Id</name>
-</id>
-```
-
-Champs de Configuration:
-
--   `name` – The name of the column with keys.
-
-Pour DDL-requête:
-
-``` sql
-CREATE DICTIONARY (
-    Id UInt64,
-    ...
-)
-PRIMARY KEY Id
-...
-```
-
--   `PRIMARY KEY` – The name of the column with keys.
-
-### Clé Composite {#composite-key}
-
-La clé peut être un `tuple` de tous les types de champs. Le [disposition](external-dicts-dict-layout.md) dans ce cas, doit être `complex_key_hashed` ou `complex_key_cache`.
-
-!!! tip "Conseil"
-    Une clé composite peut être constitué d'un seul élément. Cela permet d'utiliser une chaîne comme clé, par exemple.
-
-La structure de clé est définie dans l'élément `<key>`. Les principaux champs sont spécifiés dans le même format que le dictionnaire [attribut](external-dicts-dict-structure.md). Exemple:
-
-``` xml
-<structure>
-    <key>
-        <attribute>
-            <name>field1</name>
-            <type>String</type>
-        </attribute>
-        <attribute>
-            <name>field2</name>
-            <type>UInt32</type>
-        </attribute>
-        ...
-    </key>
-...
-```
-
-ou
-
-``` sql
-CREATE DICTIONARY (
-    field1 String,
-    field2 String
-    ...
-)
-PRIMARY KEY field1, field2
-...
-```
-
-Pour une requête à l' `dictGet*` fonction, un tuple est passé comme clé. Exemple: `dictGetString('dict_name', 'attr_name', tuple('string for field1', num_for_field2))`.
-
-## Attribut {#ext_dict_structure-attributes}
-
-Exemple de Configuration:
-
-``` xml
-<structure>
-    ...
-    <attribute>
-        <name>Name</name>
-        <type>ClickHouseDataType</type>
-        <null_value></null_value>
-        <expression>rand64()</expression>
-        <hierarchical>true</hierarchical>
-        <injective>true</injective>
-        <is_object_id>true</is_object_id>
-    </attribute>
-</structure>
-```
-
-ou
-
-``` sql
-CREATE DICTIONARY somename (
-    Name ClickHouseDataType DEFAULT '' EXPRESSION rand64() HIERARCHICAL INJECTIVE IS_OBJECT_ID
-)
-```

-# Dictionnaires Externes {#dicts-external-dicts}
-
-Vous pouvez ajouter vos propres dictionnaires à partir de diverses sources de données. La source de données d'un dictionnaire peut être un texte local ou un fichier exécutable, une ressource HTTP(S) ou un autre SGBD. Pour plus d'informations, voir “[Sources pour les dictionnaires externes](external-dicts-dict-sources.md)”.
-
-ClickHouse:
-
--   Stocke entièrement ou partiellement les dictionnaires en RAM.
--   Met à jour périodiquement les dictionnaires et charge dynamiquement les valeurs manquantes. En d'autres mots, les dictionnaires peuvent être chargés dynamiquement.
--   Permet de créer des dictionnaires externes avec des fichiers xml ou [Les requêtes DDL](../../statements/create.md#create-dictionary-query).
-
-La configuration des dictionnaires externes peut être située dans un ou plusieurs fichiers xml. Le chemin d'accès à la configuration spécifiée dans le [dictionaries_config](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-dictionaries_config) paramètre.
-
-Les dictionnaires peuvent être chargés au démarrage du serveur ou à la première utilisation, en fonction [dictionaries_lazy_load](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-dictionaries_lazy_load) paramètre.
-
-Le [dictionnaire](../../../operations/system-tables.md#system_tables-dictionaries) la table système contient des informations sur les dictionnaires configurés sur le serveur. Pour chaque dictionnaire, vous pouvez y trouver:
-
--   Statut du dictionnaire.
--   Paramètres de Configuration.
--   Des métriques telles que la quantité de RAM allouée pour le dictionnaire ou un certain nombre de requêtes depuis que le dictionnaire a été chargé avec succès.
-
-Le fichier de configuration du dictionnaire a le format suivant:
-
-``` xml
-<yandex>
-    <comment>An optional element with any content. Ignored by the ClickHouse server.</comment>
-
-    <!--Optional element. File name with substitutions-->
-    <include_from>/etc/metrika.xml</include_from>
-
-
-    <dictionary>
-        <!-- Dictionary configuration. -->
-        <!-- There can be any number of <dictionary> sections in the configuration file. -->
-    </dictionary>
-
-</yandex>
-```
-
-Vous pouvez [configurer](external-dicts-dict.md) le nombre de dictionnaires dans le même fichier.
-
-[Requêtes DDL pour les dictionnaires](../../statements/create.md#create-dictionary-query) ne nécessite aucun enregistrement supplémentaire dans la configuration du serveur. Ils permettent de travailler avec des dictionnaires en tant qu'entités de première classe, comme des tables ou des vues.
-
-!!! attention "Attention"
-    Vous pouvez convertir les valeurs pour un petit dictionnaire en le décrivant dans un `SELECT` requête (voir la [transformer](../../../sql-reference/functions/other-functions.md) fonction). Cette fonctionnalité n'est pas liée aux dictionnaires externes.

-# Dictionnaire {#dictionaries}
-
-Un dictionnaire est une cartographie (`key -> attributes`) qui est pratique pour différents types de listes de référence.
-
-ClickHouse prend en charge des fonctions spéciales pour travailler avec des dictionnaires qui peuvent être utilisés dans les requêtes. Il est plus facile et plus efficace d'utiliser des dictionnaires avec des fonctions que par une `JOIN` avec des tableaux de référence.
-
-[NULL](../../sql-reference/syntax.md#null-literal) les valeurs ne peuvent pas être stockées dans un dictionnaire.
-
-Supports ClickHouse:
-
--   [Construit-dans les dictionnaires](internal-dicts.md#internal_dicts) avec un [ensemble de fonctions](../../sql-reference/functions/ym-dict-functions.md).
--   [Plug-in (externe) dictionnaires](external-dictionaries/external-dicts.md#dicts-external-dicts) avec un [ensemble de fonctions](../../sql-reference/functions/ext-dict-functions.md).

----
-
-# Dictionnaires Internes {#internal_dicts}
-
-ClickHouse contient une fonction intégrée pour travailler avec une géobase.
-
-Cela vous permet de:
-
--   Utilisez L'ID d'une région pour obtenir son nom dans la langue souhaitée.
--   Utilisez L'ID d'une région pour obtenir L'ID d'une ville, d'une région, d'un district fédéral, d'un pays ou d'un continent.
--   Vérifiez si une région fait partie d'une autre région.
--   Obtenez une chaîne de régions parentes.
-
-Toutes les fonctions prennent en charge “translocality,” la capacité d'utiliser simultanément différentes perspectives sur la propriété de la région. Pour plus d'informations, consultez la section “Functions for working with Yandex.Metrica dictionaries”.
-
-Les dictionnaires internes sont désactivés dans le package par défaut.
-Pour les activer, décommentez les paramètres `path_to_regions_hierarchy_file` et `path_to_regions_names_files` dans le fichier de configuration du serveur.
-
-La géobase est chargée à partir de fichiers texte.
-
-Place de la `regions_hierarchy*.txt` les fichiers dans le `path_to_regions_hierarchy_file` répertoire. Ce paramètre de configuration doit contenir le chemin `regions_hierarchy.txt` fichier (la hiérarchie régionale par défaut), et les autres fichiers (`regions_hierarchy_ua.txt`) doit être situé dans le même répertoire.
-
-Mettre le `regions_names_*.txt` les fichiers dans le `path_to_regions_names_files` répertoire.
-
-Vous pouvez également créer ces fichiers vous-même. Le format de fichier est le suivant:
-
-`regions_hierarchy*.txt`: TabSeparated (pas d'en-tête), colonnes:
-
--   région de l'ID (`UInt32`)
--   ID de région parent (`UInt32`)
--   type de région (`UInt8`): 1-continent, 3-pays, 4-district fédéral, 5-région, 6-ville; les autres types n'ont pas de valeurs
--   population (`UInt32`) — optional column
-
-`regions_names_*.txt`: TabSeparated (pas d'en-tête), colonnes:
-
--   région de l'ID (`UInt32`)
--   nom de la région (`String`) — Can't contain tabs or line feeds, even escaped ones.
-
-Un tableau plat est utilisé pour stocker dans la RAM. Pour cette raison, les ID ne devraient pas dépasser un million.
-
-Les dictionnaires peuvent être mis à jour sans redémarrer le serveur. Cependant, l'ensemble des dictionnaires n'est pas mis à jour.
-Pour les mises à jour, les temps de modification du fichier sont vérifiés. Si un fichier a été modifié, le dictionnaire est mis à jour.
-L'intervalle de vérification des modifications est configuré dans le `builtin_dictionaries_reload_interval` paramètre.
-Les mises à jour du dictionnaire (autres que le chargement lors de la première utilisation) ne bloquent pas les requêtes. Lors des mises à jour, les requêtes utilisent les anciennes versions des dictionnaires. Si une erreur se produit pendant une mise à jour, l'erreur est écrite dans le journal du serveur et les requêtes continuent d'utiliser l'ancienne version des dictionnaires.
-
-Nous vous recommandons de mettre à jour périodiquement les dictionnaires avec la géobase. Lors d'une mise à jour, générez de nouveaux fichiers et écrivez-les dans un emplacement séparé. Lorsque tout est prêt, renommez - les en fichiers utilisés par le serveur.
-
-Il existe également des fonctions pour travailler avec les identifiants du système d'exploitation et Yandex.Moteurs de recherche Metrica, mais ils ne devraient pas être utilisés.

-# Fonctions Arithmétiques {#arithmetic-functions}
-
-Pour toutes les fonctions arithmétiques, le type de résultat est calculé comme le plus petit type de nombre dans lequel le résultat correspond, s'il existe un tel type. Le minimum est pris simultanément sur la base du nombre de bits, s'il est signé, et s'il flotte. S'il n'y a pas assez de bits, le type de bits le plus élevé est pris.
-
-Exemple:
-
-``` sql
-SELECT toTypeName(0), toTypeName(0 + 0), toTypeName(0 + 0 + 0), toTypeName(0 + 0 + 0 + 0)
-```
-
-``` text
-┌─toTypeName(0)─┬─toTypeName(plus(0, 0))─┬─toTypeName(plus(plus(0, 0), 0))─┬─toTypeName(plus(plus(plus(0, 0), 0), 0))─┐
-│ UInt8         │ UInt16                 │ UInt32                          │ UInt64                                   │
-└───────────────┴────────────────────────┴─────────────────────────────────┴──────────────────────────────────────────┘
-```
-
-Les fonctions arithmétiques fonctionnent pour n'importe quelle paire de types de UInt8, UInt16, UInt32, UInt64, Int8, Int16, Int32, Int64, Float32 ou Float64.
-
-Le débordement est produit de la même manière qu'en C++.
-
-## plus (A, B), opérateur a + b {#plusa-b-a-b-operator}
-
-Calcule la somme des nombres.
-Vous pouvez également ajouter des nombres entiers avec une date ou la date et l'heure. Dans le cas d'une date, Ajouter un entier signifie ajouter le nombre de jours correspondant. Pour une date avec l'heure, cela signifie ajouter le nombre de secondes correspondant.
-
-## moins (A, B), opérateur a - b {#minusa-b-a-b-operator}
-
-Calcule la différence. Le résultat est toujours signé.
-
-You can also calculate integer numbers from a date or date with time. The idea is the same – see above for ‘plus’.
-
-## la multiplication(a, b), a \* et b \* de l'opérateur {#multiplya-b-a-b-operator}
-
-Calcule le produit des nombres.
-
-## diviser (A, B), opérateur a / b {#dividea-b-a-b-operator}
-
-Calcule le quotient des nombres. Le type de résultat est toujours un type à virgule flottante.
-Il n'est pas de division entière. Pour la division entière, utilisez le ‘intDiv’ fonction.
-En divisant par zéro vous obtenez ‘inf’, ‘-inf’, ou ‘nan’.
-
-## intDiv (a, b) {#intdiva-b}
-
-Calcule le quotient des nombres. Divise en entiers, arrondi vers le bas (par la valeur absolue).
-Une exception est levée en divisant par zéro ou en divisant un nombre négatif minimal par moins un.
-
-## intDivOrZero(a, b) {#intdivorzeroa-b}
-
-Diffère de ‘intDiv’ en ce sens qu'il renvoie zéro en divisant par zéro ou en divisant un nombre négatif minimal par moins un.
-
-## opérateur modulo(A, B), A % B {#moduloa-b-a-b-operator}
-
-Calcule le reste après la division.
-Si les arguments sont des nombres à virgule flottante, ils sont pré-convertis en entiers en supprimant la partie décimale.
-Le reste est pris dans le même sens qu'en C++. La division tronquée est utilisée pour les nombres négatifs.
-Une exception est levée en divisant par zéro ou en divisant un nombre négatif minimal par moins un.
-
-## moduloOrZero (a, b) {#moduloorzeroa-b}
-
-Diffère de ‘modulo’ en ce sens qu'il renvoie zéro lorsque le diviseur est nul.
-
-## annuler (a), - un opérateur {#negatea-a-operator}
-
-Calcule un nombre avec le signe inverse. Le résultat est toujours signé.
-
-## abs(un) {#arithm_func-abs}
-
-Calcule la valeur absolue d'un nombre (un). Autrement dit, si un \< 0, Il renvoie-A. pour les types non signés, il ne fait rien. Pour les types entiers signés, il renvoie un nombre non signé.
-
-## pgcd(a, b) {#gcda-b}
-
-Renvoie le plus grand diviseur commun des nombres.
-Une exception est levée en divisant par zéro ou en divisant un nombre négatif minimal par moins un.
-
-## ppcm(a, b) {#lcma-b}
-
-Renvoie le multiple le moins commun des nombres.
-Une exception est levée en divisant par zéro ou en divisant un nombre négatif minimal par moins un.

-
-## plage (fin), Plage(début, fin \[, étape\]) {#rangeend-rangestart-end-step}
-
-Retourne un tableau de nombres du début à la fin-1 par étape.
-Si l'argument `start` n'est pas spécifié, la valeur par défaut est 0.
-Si l'argument `step` n'est pas spécifié, la valeur par défaut est 1.
-Il se comporte presque comme pythonic `range`. Mais la différence est que tous les types d'arguments doivent être `UInt` nombre.
-Juste au cas où, une exception est levée si des tableaux d'une longueur totale de plus de 100 000 000 d'éléments sont créés dans un bloc de données.
-
-## array(x1, …), operator \[x1, …\] {#arrayx1-operator-x1}
-
-Crée un tableau à partir des arguments de la fonction.
-Les arguments doivent être des constantes et avoir des types qui ont le plus petit type commun. Au moins un argument doit être passé, sinon il n'est pas clair quel type de tableau créer. Qui est, vous ne pouvez pas utiliser cette fonction pour créer un tableau vide (pour ce faire, utilisez la ‘emptyArray\*’ la fonction décrite ci-dessus).
-Retourne un ‘Array(T)’ type de résultat, où ‘T’ est le plus petit type commun parmi les arguments passés.
-
-## arrayConcat {#arrayconcat}
-
-Combine des tableaux passés comme arguments.
-
-``` sql
-arrayConcat(arrays)
-```
-
-**Paramètre**
-
--   `arrays` – Arbitrary number of arguments of [Tableau](../../sql-reference/data-types/array.md) type.
-    **Exemple**
-
-<!-- -->

-Les index dans un tableau commencent à partir d'un.
-Les index négatifs sont pris en charge. Dans ce cas, il sélectionne l'élément correspondant numérotées à partir de la fin. Exemple, `arr[-1]` est le dernier élément du tableau.
-
-Si l'index est en dehors des limites d'un tableau, il renvoie une valeur (0 pour les nombres, une chaîne vide pour les cordes, etc.), sauf pour le cas avec un tableau non constant et un index constant 0 (dans ce cas, il y aura une erreur `Array indices are 1-based`).
-
-## a (arr, elem) {#hasarr-elem}
-
-Vérifie si le ‘arr’ tableau a la ‘elem’ élément.
-Retourne 0 si l'élément n'est pas dans le tableau, ou 1 si elle l'est.

-
--   `1`, si `set` contient tous les éléments de `subset`.
--   `0`, autrement.
-
-**Propriétés particulières**
-
--   Un tableau vide est un sous-ensemble d'un tableau quelconque.
--   `Null` traitée comme une valeur.
--   Ordre des valeurs dans les deux tableaux n'a pas d'importance.
-
-**Exemple**
-
-`SELECT hasAll([], [])` retours 1.
-
-`SELECT hasAll([1, Null], [Null])` retours 1.
-
-`SELECT hasAll([1.0, 2, 3, 4], [1, 3])` retours 1.
-
-`SELECT hasAll(['a', 'b'], ['a'])` retours 1.
-
-`SELECT hasAll([1], ['a'])` renvoie 0.

-`SELECT hasAll([[1, 2], [3, 4]], [[1, 2], [3, 5]])` renvoie 0.
-
-## hasAny {#hasany}
-
-Vérifie si deux tableaux ont une intersection par certains éléments.
-
-``` sql
-hasAny(array1, array2)
-```
-
-**Paramètre**
-
--   `array1` – Array of any type with a set of elements.
--   `array2` – Array of any type with a set of elements.
-
-**Les valeurs de retour**
-
--   `1`, si `array1` et `array2` avoir un élément similaire au moins.
--   `0`, autrement.
-
-**Propriétés particulières**
-
--   `Null` traitée comme une valeur.
--   Ordre des valeurs dans les deux tableaux n'a pas d'importance.
-
-**Exemple**
-
-`SELECT hasAny([1], [])` retourner `0`.
-
-`SELECT hasAny([Null], [Null, 1])` retourner `1`.
-
-`SELECT hasAny([-128, 1., 512], [1])` retourner `1`.
-
-`SELECT hasAny([[1, 2], [3, 4]], ['a', 'c'])` retourner `0`.
-
-`SELECT hasAll([[1, 2], [3, 4]], [[1, 2], [1, 2]])` retourner `1`.
-
-## indexOf (arr, x) {#indexofarr-x}
-
-Renvoie l'index de la première ‘x’ élément (à partir de 1) s'il est dans le tableau, ou 0 s'il ne l'est pas.
-
-Exemple:
-
-``` sql
-SELECT indexOf([1, 3, NULL, NULL], NULL)
-```
-
-``` text
-┌─indexOf([1, 3, NULL, NULL], NULL)─┐
-│                                 3 │
-└───────────────────────────────────┘
-```
-
-Ensemble d'éléments de `NULL` sont traités comme des valeurs normales.
-
-## countEqual (arr, x) {#countequalarr-x}
-
-Renvoie le nombre d'éléments dans le tableau égal à X. équivalent à arrayCount (elem - \> elem = x, arr).
-
-`NULL` les éléments sont traités comme des valeurs distinctes.
-
-Exemple:
-
-``` sql
-SELECT countEqual([1, 2, NULL, NULL], NULL)
-```
-
-``` text
-┌─countEqual([1, 2, NULL, NULL], NULL)─┐
-│                                    2 │
-└──────────────────────────────────────┘
-```
-
-## arrayEnumerate (arr) {#array_functions-arrayenumerate}
-
-Returns the array \[1, 2, 3, …, length (arr) \]
-
-Cette fonction est normalement utilisée avec ARRAY JOIN. Il permet de compter quelque chose une seule fois pour chaque tableau après l'application de la jointure de tableau. Exemple:
-
-``` sql
-SELECT
-    count() AS Reaches,
-    countIf(num = 1) AS Hits
-FROM test.hits
-ARRAY JOIN
-    GoalsReached,
-    arrayEnumerate(GoalsReached) AS num
-WHERE CounterID = 160656
-LIMIT 10
-```
-
-``` text
-┌─Reaches─┬──Hits─┐
-│   95606 │ 31406 │
-└─────────┴───────┘
-```
-
-Dans cet exemple, Reaches est le nombre de conversions (les chaînes reçues après l'application de la jointure de tableau), et Hits est le nombre de pages vues (chaînes avant la jointure de tableau). Dans ce cas particulier, vous pouvez obtenir le même résultat dans une voie plus facile:
-
-``` sql
-SELECT
-    sum(length(GoalsReached)) AS Reaches,
-    count() AS Hits
-FROM test.hits
-WHERE (CounterID = 160656) AND notEmpty(GoalsReached)
-```
-
-``` text
-┌─Reaches─┬──Hits─┐
-│   95606 │ 31406 │
-└─────────┴───────┘
-```
-
-Cette fonction peut également être utilisée dans les fonctions d'ordre supérieur. Par exemple, vous pouvez l'utiliser pour obtenir les indices de tableau pour les éléments qui correspondent à une condition.
-
-## arrayEnumerateUniq(arr, …) {#arrayenumerateuniqarr}
-
-Renvoie un tableau de la même taille que le tableau source, indiquant pour chaque élément Quelle est sa position parmi les éléments de même valeur.
-Par exemple: arrayEnumerateUniq(\[10, 20, 10, 30\]) = \[1, 1, 2, 1\].
-
-Cette fonction est utile lors de L'utilisation de la jointure de tableau et de l'agrégation d'éléments de tableau.
-Exemple:
-
-``` sql
-SELECT
-    Goals.ID AS GoalID,
-    sum(Sign) AS Reaches,
-    sumIf(Sign, num = 1) AS Visits
-FROM test.visits
-ARRAY JOIN
-    Goals,
-    arrayEnumerateUniq(Goals.ID) AS num
-WHERE CounterID = 160656
-GROUP BY GoalID
-ORDER BY Reaches DESC
-LIMIT 10
-```
-
-``` text
-┌──GoalID─┬─Reaches─┬─Visits─┐
-│   53225 │    3214 │   1097 │
-│ 2825062 │    3188 │   1097 │
-│   56600 │    2803 │    488 │
-│ 1989037 │    2401 │    365 │
-│ 2830064 │    2396 │    910 │
-│ 1113562 │    2372 │    373 │
-│ 3270895 │    2262 │    812 │
-│ 1084657 │    2262 │    345 │
-│   56599 │    2260 │    799 │
-│ 3271094 │    2256 │    812 │
-└─────────┴─────────┴────────┘
-```
-
-Dans cet exemple, chaque ID d'objectif a un calcul du nombre de conversions (chaque élément de la structure de données imbriquées objectifs est un objectif atteint, que nous appelons une conversion) et le nombre de sessions. Sans array JOIN, nous aurions compté le nombre de sessions comme sum(signe). Mais dans ce cas particulier, les lignes ont été multipliées par la structure des objectifs imbriqués, donc pour compter chaque session une fois après cela, nous appliquons une condition à la valeur de arrayEnumerateUniq(Goals.ID) fonction.
-
-La fonction arrayEnumerateUniq peut prendre plusieurs tableaux de la même taille que les arguments. Dans ce cas, l'unicité est considérée pour les tuples d'éléments dans les mêmes positions dans tous les tableaux.
-
-``` sql
-SELECT arrayEnumerateUniq([1, 1, 1, 2, 2, 2], [1, 1, 2, 1, 1, 2]) AS res
-```
-
-``` text
-┌─res───────────┐
-│ [1,2,1,1,2,1] │
-└───────────────┘
-```
-
-Ceci est nécessaire lors de L'utilisation de Array JOIN avec une structure de données imbriquée et une agrégation supplémentaire entre plusieurs éléments de cette structure.

--   `-Inf` les valeurs sont d'abord dans le tableau.
--   `NULL` les valeurs sont les derniers dans le tableau.
--   `NaN` les valeurs sont juste avant `NULL`.
--   `Inf` les valeurs sont juste avant `NaN`.
-
-Notez que `arraySort` est un [fonction d'ordre supérieur](higher-order-functions.md). Vous pouvez passer d'une fonction lambda comme premier argument. Dans ce cas, l'ordre de classement est déterminé par le résultat de la fonction lambda appliquée aux éléments de la matrice.
-
-Considérons l'exemple suivant:
-
-``` sql
-SELECT arraySort((x) -> -x, [1, 2, 3]) as res;
-```
-
-``` text
-┌─res─────┐
-│ [3,2,1] │
-└─────────┘
-```
-
-For each element of the source array, the lambda function returns the sorting key, that is, \[1 –\> -1, 2 –\> -2, 3 –\> -3\]. Since the `arraySort` fonction trie les touches dans l'ordre croissant, le résultat est \[3, 2, 1\]. Ainsi, l' `(x) –> -x` fonction lambda définit le [l'ordre décroissant](#array_functions-reverse-sort) dans un tri.
-
-La fonction lambda peut accepter plusieurs arguments. Dans ce cas, vous avez besoin de passer l' `arraySort` fonction plusieurs tableaux de longueur identique à laquelle correspondront les arguments de la fonction lambda. Le tableau résultant sera composé d'éléments du premier tableau d'entrée; les éléments du(des) Tableau (s) d'entrée suivant (s) spécifient les clés de tri. Exemple:
-
-``` sql
-SELECT arraySort((x, y) -> y, ['hello', 'world'], [2, 1]) as res;
-```
-
-``` text
-┌─res────────────────┐
-│ ['world', 'hello'] │
-└────────────────────┘
-```
-
-Ici, les éléments qui sont passés dans le deuxième tableau (\[2, 1\]) définissent une clé de tri pour l'élément correspondant à partir du tableau source (\[‘hello’, ‘world’\]), qui est, \[‘hello’ –\> 2, ‘world’ –\> 1\]. Since the lambda function doesn't use `x`, les valeurs réelles du tableau source n'affectent pas l'ordre dans le résultat. Si, ‘hello’ sera le deuxième élément du résultat, et ‘world’ sera le premier.
-
-D'autres exemples sont présentés ci-dessous.

-SELECT arraySort((x, y) -> y, [0, 1, 2], ['c', 'b', 'a']) as res;

-## arrayReverseSort(\[func,\] arr, …) {#array_functions-reverse-sort}
-
-Trie les éléments de la `arr` tableau dans l'ordre décroissant. Si l' `func` la fonction est spécifiée, `arr` est trié en fonction du résultat de la `func` fonction appliquée aux éléments du tableau, puis le tableau trié est inversé. Si `func` accepte plusieurs arguments, le `arrayReverseSort` la fonction est passé plusieurs tableaux que les arguments de `func` correspond à. Des exemples détaillés sont présentés à la fin de `arrayReverseSort` Description.
-
-Exemple de tri de valeurs entières:
-
-``` sql
-SELECT arrayReverseSort([1, 3, 3, 0]);
-```
-
-``` text
-┌─arrayReverseSort([1, 3, 3, 0])─┐
-│ [3,3,1,0]                      │
-└────────────────────────────────┘
-```
-
-Exemple de tri des valeurs de chaîne:
-
-``` sql
-SELECT arrayReverseSort(['hello', 'world', '!']);
-```
-
-``` text
-┌─arrayReverseSort(['hello', 'world', '!'])─┐
-│ ['world','hello','!']                     │
-└───────────────────────────────────────────┘
-```
-
-Considérez l'ordre de tri suivant pour le `NULL`, `NaN` et `Inf` valeur:
-
-``` sql
-SELECT arrayReverseSort([1, nan, 2, NULL, 3, nan, -4, NULL, inf, -inf]) as res;
-```
-
-``` text
-┌─res───────────────────────────────────┐
-│ [inf,3,2,1,-4,-inf,nan,nan,NULL,NULL] │
-└───────────────────────────────────────┘
-```
-
--   `Inf` les valeurs sont d'abord dans le tableau.
--   `NULL` les valeurs sont les derniers dans le tableau.
--   `NaN` les valeurs sont juste avant `NULL`.
--   `-Inf` les valeurs sont juste avant `NaN`.
-
-Notez que l' `arrayReverseSort` est un [fonction d'ordre supérieur](higher-order-functions.md). Vous pouvez passer d'une fonction lambda comme premier argument. Exemple est montré ci-dessous.
-
-``` sql
-SELECT arrayReverseSort((x) -> -x, [1, 2, 3]) as res;
-```
-
-``` text
-┌─res─────┐
-│ [1,2,3] │
-└─────────┘
-```
-
-Le tableau est trié de la façon suivante:
-
-1.  Dans un premier temps, le tableau source (\[1, 2, 3\]) est trié en fonction du résultat de la fonction lambda appliquée aux éléments du tableau. Le résultat est un tableau \[3, 2, 1\].
-2.  Tableau qui est obtenu à l'étape précédente, est renversé. Donc, le résultat final est \[1, 2, 3\].
-
-La fonction lambda peut accepter plusieurs arguments. Dans ce cas, vous avez besoin de passer l' `arrayReverseSort` fonction plusieurs tableaux de longueur identique à laquelle correspondront les arguments de la fonction lambda. Le tableau résultant sera composé d'éléments du premier tableau d'entrée; les éléments du(des) Tableau (s) d'entrée suivant (s) spécifient les clés de tri. Exemple:

-``` text
-┌─res───────────────┐
-│ ['hello','world'] │
-└───────────────────┘
-```
-
-Dans cet exemple, le tableau est trié de la façon suivante:
-
-1.  Au début, le tableau source (\[‘hello’, ‘world’\]) est triée selon le résultat de la fonction lambda appliquée aux éléments de tableaux. Les éléments qui sont passés dans le deuxième tableau (\[2, 1\]), définissent les clés de tri pour les éléments correspondants du tableau source. Le résultat est un tableau \[‘world’, ‘hello’\].
-2.  Tableau trié lors de l'étape précédente, est renversé. Donc, le résultat final est \[‘hello’, ‘world’\].

-# fonction arrayJoin {#functions_arrayjoin}
-
-C'est un très inhabituelle de la fonction.
-
-Les fonctions normales ne modifient pas un ensemble de lignes, mais modifient simplement les valeurs de chaque ligne (map).
-Les fonctions d'agrégation compriment un ensemble de lignes (plier ou réduire).
-Le ‘arrayJoin’ la fonction prend chaque ligne et génère un ensemble de lignes (dépliante).
-
-Cette fonction prend un tableau comme argument et propage la ligne source à plusieurs lignes pour le nombre d'éléments dans le tableau.
-Toutes les valeurs des colonnes sont simplement copiés, sauf les valeurs dans la colonne où cette fonction est appliquée; elle est remplacée par la valeur correspondante de tableau.
-
-Une requête peut utiliser plusieurs `arrayJoin` fonction. Dans ce cas, la transformation est effectuée plusieurs fois.
-
-Notez la syntaxe de jointure de tableau dans la requête SELECT, qui offre des possibilités plus larges.
-
-Exemple:
-
-``` sql
-SELECT arrayJoin([1, 2, 3] AS src) AS dst, 'Hello', src

-# Fonctions De Bitmap {#bitmap-functions}
-
-Les fonctions Bitmap fonctionnent pour le calcul de la valeur de L'objet de deux bitmaps, il s'agit de renvoyer un nouveau bitmap ou une cardinalité tout en utilisant le calcul de la formule, tel que and, or, xor, and not, etc.
-
-Il existe 2 types de méthodes de construction pour L'objet Bitmap. L'un doit être construit par la fonction d'agrégation groupBitmap avec-State, l'autre doit être construit par L'objet Array. Il est également de convertir L'objet Bitmap en objet tableau.
-
-RoaringBitmap est enveloppé dans une structure de données pendant le stockage réel des objets Bitmap. Lorsque la cardinalité est inférieure ou égale à 32, elle utilise Set objet. Lorsque la cardinalité est supérieure à 32, elle utilise l'objet RoaringBitmap. C'est pourquoi le stockage de faible cardinalité jeu est plus rapide.
-
-Pour plus d'informations sur RoaringBitmap, voir: [CRoaring](https://github.com/RoaringBitmap/CRoaring).

-# Fonctions De Comparaison {#comparison-functions}
-
-Les fonctions de comparaison renvoient toujours 0 ou 1 (Uint8).
-
-Les types suivants peuvent être comparés:
-
--   nombre
--   cordes et cordes fixes
--   date
--   dates avec heures
-
-au sein de chaque groupe, mais pas entre différents groupes.
-
-Par exemple, vous ne pouvez pas comparer une date avec une chaîne. Vous devez utiliser une fonction pour convertir la chaîne en une date, ou vice versa.
-
-Les chaînes sont comparées par octets. Une courte chaîne est plus petite que toutes les chaînes qui commencent par elle et qui contiennent au moins un caractère de plus.

-# Fonctions Conditionnelles {#conditional-functions}
-
-## si {#if}
-
-Contrôle la ramification conditionnelle. Contrairement à la plupart des systèmes, ClickHouse évalue toujours les deux expressions `then` et `else`.
-
-**Syntaxe**
-
-``` sql
-SELECT if(cond, then, else)
-```
-
-Si la condition `cond` renvoie une valeur non nulle, retourne le résultat de l'expression `then` et le résultat de l'expression `else`, si présent, est ignoré. Si l' `cond` est égal à zéro ou `NULL` alors le résultat de la `then` l'expression est ignorée et le résultat de `else` expression, si elle est présente, est renvoyée.
-
-**Paramètre**
-
--   `cond` – The condition for evaluation that can be zero or not. The type is UInt8, Nullable(UInt8) or NULL.
--   `then` - L'expression à renvoyer si la condition est remplie.
--   `else` - L'expression à renvoyer si la condition n'est pas remplie.
-
-**Valeurs renvoyées**
-
-La fonction s'exécute `then` et `else` expressions et retourne son résultat, selon que la condition `cond` fini par être zéro ou pas.
-
-**Exemple**
-
-Requête:
-
-``` sql
-SELECT if(1, plus(2, 2), plus(2, 6))
-```
-
-Résultat:
-
-``` text
-┌─plus(2, 2)─┐

-
-Résultat:
-
-``` text
-┌─plus(2, 6)─┐
-│          8 │
-└────────────┘
-```
-
--   `then` et `else` doit avoir le type commun le plus bas.
-
-**Exemple:**
-
-Prendre cette `LEFT_RIGHT` table:
-
-``` sql
-SELECT *
-FROM LEFT_RIGHT

-Note: `NULL` les valeurs ne sont pas utilisés dans cet exemple, vérifier [Valeurs nulles dans les conditions](#null-values-in-conditionals) section.
-
-## Opérateur Ternaire {#ternary-operator}
-
-Il fonctionne même comme `if` fonction.
-
-Syntaxe: `cond ? then : else`
-
-Retourner `then` si l' `cond` renvoie la valeur vrai (supérieur à zéro), sinon renvoie `else`.
-
--   `cond` doit être de type de `UInt8`, et `then` et `else` doit avoir le type commun le plus bas.
-
--   `then` et `else` peut être `NULL`
-
-**Voir aussi**
-
--   [ifNotFinite](other-functions.md#ifnotfinite).
-
-## multiIf {#multiif}
-
-Permet d'écrire le [CASE](../operators/index.md#operator_case) opérateur plus compacte dans la requête.
-
-Syntaxe: `multiIf(cond_1, then_1, cond_2, then_2, ..., else)`
-
-**Paramètre:**
-
--   `cond_N` — The condition for the function to return `then_N`.
--   `then_N` — The result of the function when executed.
--   `else` — The result of the function if none of the conditions is met.
-
-La fonction accepte `2N+1` paramètre.
-
-**Valeurs renvoyées**
-
-La fonction renvoie l'une des valeurs `then_N` ou `else` selon les conditions `cond_N`.
-
-**Exemple**
-
-En utilisant à nouveau `LEFT_RIGHT` table.
-
-``` sql
-SELECT
-    left,
-    right,
-    multiIf(left < right, 'left is smaller', left > right, 'left is greater', left = right, 'Both equal', 'Null value') AS result
-FROM LEFT_RIGHT
-
-┌─left─┬─right─┬─result──────────┐
-│ ᴺᵁᴸᴸ │     4 │ Null value      │
-│    1 │     3 │ left is smaller │
-│    2 │     2 │ Both equal      │
-│    3 │     1 │ left is greater │
-│    4 │  ᴺᵁᴸᴸ │ Null value      │
-└──────┴───────┴─────────────────┘
-```
-
-## Utilisation Directe Des Résultats Conditionnels {#using-conditional-results-directly}
-
-Les conditions entraînent toujours `0`, `1` ou `NULL`. Vous pouvez donc utiliser des résultats conditionnels directement comme ceci:
-
-``` sql
-SELECT left < right AS is_small
-FROM LEFT_RIGHT
-
-┌─is_small─┐
-│     ᴺᵁᴸᴸ │
-│        1 │
-│        0 │
-│        0 │
-│     ᴺᵁᴸᴸ │
-└──────────┘
-```
-
-## Valeurs nulles dans les conditions {#null-values-in-conditionals}
-
-Lorsque `NULL` les valeurs sont impliqués dans des conditions, le résultat sera également `NULL`.
-
-``` sql
-SELECT
-    NULL < 1,
-    2 < NULL,
-    NULL < NULL,
-    NULL = NULL
-
-┌─less(NULL, 1)─┬─less(2, NULL)─┬─less(NULL, NULL)─┬─equals(NULL, NULL)─┐
-│ ᴺᵁᴸᴸ          │ ᴺᵁᴸᴸ          │ ᴺᵁᴸᴸ             │ ᴺᵁᴸᴸ               │
-└───────────────┴───────────────┴──────────────────┴────────────────────┘
-```
-
-Donc, vous devriez construire vos requêtes avec soin si les types sont `Nullable`.
-
-L'exemple suivant le démontre en omettant d'ajouter la condition égale à `multiIf`.
-
-``` sql
-SELECT
-    left,
-    right,
-    multiIf(left < right, 'left is smaller', left > right, 'right is smaller', 'Both equal') AS faulty_result
-FROM LEFT_RIGHT
-
-┌─left─┬─right─┬─faulty_result────┐

-│    1 │     3 │ left is smaller  │
-│    2 │     2 │ Both equal       │
-│    3 │     1 │ right is smaller │
-│    4 │  ᴺᵁᴸᴸ │ Both equal       │

-# Fonctions pour travailler avec des Dates et des heures {#functions-for-working-with-dates-and-times}
-
-Support des fuseaux horaires
-
-Toutes les fonctions pour travailler avec la date et l'heure qui ont une logique d'utilisation pour le fuseau horaire peut accepter un second fuseau horaire argument. Exemple: Asie / Ekaterinbourg. Dans ce cas, ils utilisent le fuseau horaire spécifié au lieu du fuseau horaire local (par défaut).
-
-``` sql
-SELECT
-    toDateTime('2016-06-15 23:00:00') AS time,
-    toDate(time) AS date_local,
-    toDate(time, 'Asia/Yekaterinburg') AS date_yekat,
-    toString(time, 'US/Samoa') AS time_samoa
-```

-Cette fonction renvoie le numéro de semaine pour date ou datetime. La forme à deux arguments de toWeek() vous permet de spécifier si la semaine commence le dimanche ou le lundi et si la valeur de retour doit être comprise entre 0 et 53 ou entre 1 et 53. Si l'argument mode est omis, le mode par défaut est 0.
-`toISOWeek()`est une fonction de compatibilité équivalente à `toWeek(date,3)`.
-Le tableau suivant décrit le fonctionnement de l'argument mode.
-
-| Mode | Premier jour de la semaine | Gamme | Week 1 is the first week …       |
-|------|----------------------------|-------|----------------------------------|
-| 0    | Dimanche                   | 0-53  | avec un dimanche cette année     |
-| 1    | Lundi                      | 0-53  | avec 4 jours ou plus cette année |
-| 2    | Dimanche                   | 1-53  | avec un dimanche cette année     |

-| 9    | Lundi                      | 1-53  | contient Janvier 1               |
-
-Pour les valeurs de mode avec une signification de “with 4 or more days this year,” les semaines sont numérotées selon ISO 8601: 1988:
-
--   Si la semaine contenant Janvier 1 A 4 jours ou plus dans la nouvelle année, il est Semaine 1.
-
--   Sinon, c'est la dernière semaine de l'année précédente, et la semaine prochaine est la semaine 1.
-
-Pour les valeurs de mode avec une signification de “contains January 1”, la semaine contient Janvier 1 est Semaine 1. Peu importe combien de jours dans la nouvelle année la semaine contenait, même si elle contenait seulement un jour.
-
-``` sql
-toWeek(date, [, mode][, Timezone])
-```
-
-**Paramètre**
-
--   `date` – Date or DateTime.
--   `mode` – Optional parameter, Range of values is \[0,9\], default is 0.
--   `Timezone` – Optional parameter, it behaves like any other conversion function.
-
-**Exemple**
-
-``` sql
-SELECT toDate('2016-12-27') AS date, toWeek(date) AS week0, toWeek(date,1) AS week1, toWeek(date,9) AS week9;
-```
-

-│ 2016-12-27 │    52 │    52 │     1 │
-└────────────┴───────┴───────┴───────┘
-```
-
-## toYearWeek (date \[, mode\]) {#toyearweekdatemode}
-
-Retourne l'année et la semaine pour une date. L'année dans le résultat peut être différente de l'année dans l'argument date pour la première et la dernière semaine de l'année.
-
-L'argument mode fonctionne exactement comme l'argument mode de toWeek(). Pour la syntaxe à argument unique, une valeur de mode de 0 est utilisée.
-
-`toISOYear()`est une fonction de compatibilité équivalente à `intDiv(toYearWeek(date,3),100)`.
-
-**Exemple**
-
-``` sql
-SELECT toDate('2016-12-27') AS date, toYearWeek(date) AS yearWeek0, toYearWeek(date,1) AS yearWeek1, toYearWeek(date,9) AS yearWeek9;
-```

-
-## maintenant {#now}
-
-Accepte zéro argument et renvoie l'heure actuelle à l'un des moments de l'exécution de la requête.
-Cette fonction renvoie une constante, même si la requête a pris beaucoup de temps à compléter.
-
-## aujourd' {#today}
-
-Accepte zéro argument et renvoie la date actuelle à l'un des moments de l'exécution de la requête.
-Le même que ‘toDate(now())’.
-
-## hier {#yesterday}
-
-Accepte zéro argument et renvoie la date d'hier à l'un des moments de l'exécution de la requête.
-Le même que ‘today() - 1’.
-
-## l'horaire de diffusion {#timeslot}
-
-Arrondit le temps à la demi-heure.
-Cette fonction est spécifique à Yandex.Metrica, car une demi-heure est le temps minimum pour diviser une session en deux sessions si une balise de suivi affiche les pages vues consécutives d'un seul utilisateur qui diffèrent dans le temps de strictement plus que ce montant. Cela signifie que les tuples (l'ID de balise, l'ID utilisateur et l'intervalle de temps) peuvent être utilisés pour rechercher les pages vues incluses dans la session correspondante.

-# L'Encodage Des Fonctions {#encoding-functions}
-
-## char {#char}
-
-Retourne la chaîne avec la longueur que le nombre d'arguments passés et chaque octet a la valeur de l'argument correspondant. Accepte plusieurs arguments de types numériques. Si la valeur de l'argument est hors de portée du type de données UInt8, elle est convertie en UInt8 avec arrondi et débordement possibles.
-
-**Syntaxe**
-
-``` sql
-char(number_1, [number_2, ..., number_n]);
-```
-
-**Paramètre**
-
--   `number_1, number_2, ..., number_n` — Numerical arguments interpreted as integers. Types: [Int](../../sql-reference/data-types/int-uint.md), [Flottant](../../sql-reference/data-types/float.md).
-
-**Valeur renvoyée**
-
--   une chaîne d'octets.
-
-Type: `String`.
-
-**Exemple**
-
-Requête:
-
-``` sql
-SELECT char(104.1, 101, 108.9, 108.9, 111) AS hello
-```
-
-Résultat:
-
-``` text
-┌─hello─┐
-│ hello │
-└───────┘
-```
-
-Vous pouvez construire une chaîne de codage arbitraire en passant les octets correspondants. Voici un exemple pour UTF-8:
-
-Requête:
-
-``` sql
-SELECT char(0xD0, 0xBF, 0xD1, 0x80, 0xD0, 0xB8, 0xD0, 0xB2, 0xD0, 0xB5, 0xD1, 0x82) AS hello;
-```
-
-Résultat:
-
-``` text
-┌─hello──┐
-│ привет │
-└────────┘
-```
-
-Requête:
-
-``` sql
-SELECT char(0xE4, 0xBD, 0xA0, 0xE5, 0xA5, 0xBD) AS hello;
-```
-
-Résultat:
-
-``` text
-┌─hello─┐
-│ 你好  │
-└───────┘
-```
-
-## Hex {#hex}
-
-Renvoie une chaîne contenant la représentation hexadécimale de l'argument.
-
-**Syntaxe**
-
-``` sql
-hex(arg)
-```
-
-La fonction utilise des lettres majuscules `A-F` et ne pas utiliser de préfixes (comme `0x`) ou suffixes (comme `h`).
-
-Pour les arguments entiers, il imprime des chiffres hexadécimaux (“nibbles”) du plus significatif au moins significatif (big endian ou “human readable” ordre). Il commence par l'octet non nul le plus significatif (les octets de début zéro sont omis) mais imprime toujours les deux chiffres de chaque octet même si le chiffre de début est nul.
-
-Exemple:
-
-**Exemple**
-
-Requête:
-
-``` sql
-SELECT hex(1);
-```
-
-Résultat:
-
-``` text
-01
-```
-
-Les valeurs de type `Date` et `DateTime` sont formatés comme des entiers correspondants (le nombre de jours depuis Epoch pour Date et la valeur de L'horodatage Unix pour DateTime).
-
-Pour `String` et `FixedString`, tous les octets sont simplement codés en deux nombres hexadécimaux. Zéro octets ne sont pas omis.
-
-Les valeurs des types virgule flottante et décimale sont codées comme leur représentation en mémoire. Comme nous soutenons l'architecture little endian, ils sont codés dans little endian. Zéro octets de début / fin ne sont pas omis.
-
-**Paramètre**
-
--   `arg` — A value to convert to hexadecimal. Types: [Chaîne](../../sql-reference/data-types/string.md), [UInt](../../sql-reference/data-types/int-uint.md), [Flottant](../../sql-reference/data-types/float.md), [Décimal](../../sql-reference/data-types/decimal.md), [Date](../../sql-reference/data-types/date.md) ou [DateTime](../../sql-reference/data-types/datetime.md).
-
-**Valeur renvoyée**
-
--   Une chaîne avec la représentation hexadécimale de l'argument.
-
-Type: `String`.
-
-**Exemple**
-
-Requête:
-
-``` sql
-SELECT hex(toFloat32(number)) as hex_presentation FROM numbers(15, 2);
-```
-
-Résultat:
-

-┌─hex_presentation─┐
-│ 00007041         │
-│ 00008041         │
-└──────────────────┘
-```
-
-Requête:
-
-``` sql
-SELECT hex(toFloat64(number)) as hex_presentation FROM numbers(15, 2);
-```
-
-Résultat:
-
-``` text
-┌─hex_presentation─┐
-│ 0000000000002E40 │
-│ 0000000000003040 │
-└──────────────────┘
-```
-
-## unhex (str) {#unhexstr}
-
-Accepte une chaîne contenant un nombre quelconque de chiffres hexadécimaux, et renvoie une chaîne contenant le correspondant octets. Prend en charge les lettres majuscules et minuscules A-F. Le nombre de chiffres hexadécimaux ne doit pas être pair. S'il est impair, le dernier chiffre est interprété comme la moitié la moins significative de l'octet 00-0F. Si la chaîne d'argument contient autre chose que des chiffres hexadécimaux, un résultat défini par l'implémentation est renvoyé (une exception n'est pas levée).
-Si vous voulez convertir le résultat en un nombre, vous pouvez utiliser le ‘reverse’ et ‘reinterpretAsType’ fonction.
-
-## UUIDStringToNum (str) {#uuidstringtonumstr}
-
-Accepte une chaîne contenant 36 caractères dans le format `123e4567-e89b-12d3-a456-426655440000`, et le renvoie comme un ensemble d'octets dans un FixedString (16).
-
-## UUIDNumToString (str) {#uuidnumtostringstr}

-Accepte un entier. Renvoie une chaîne contenant la liste des puissances de deux qui totalisent le nombre source lorsqu'il est additionné. Ils sont séparés par des virgules sans espaces au format texte, dans l'ordre croissant.
-
-## bitmaskToArray(num) {#bitmasktoarraynum}
-
-Accepte un entier. Renvoie un tableau de nombres UInt64 contenant la liste des puissances de deux qui totalisent le nombre source lorsqu'il est additionné. Les numéros dans le tableau sont dans l'ordre croissant.

-# Les Fonctions De Hachage {#hash-functions}
-
-Les fonctions de hachage peuvent être utilisées pour le brassage pseudo-aléatoire déterministe des éléments.
-
-## halfMD5 {#hash-functions-halfmd5}
-
-[Interpréter](../../sql-reference/functions/type-conversion-functions.md#type_conversion_functions-reinterpretAsString) tous les paramètres d'entrée sous forme de chaînes et calcule le [MD5](https://en.wikipedia.org/wiki/MD5) la valeur de hachage pour chacun d'eux. Puis combine les hachages, prend les 8 premiers octets du hachage de la chaîne résultante, et les interprète comme `UInt64` dans l'ordre des octets big-endian.
-
-``` sql
-halfMD5(par1, ...)
-```
-
-La fonction est relativement lente (5 millions de chaînes courtes par seconde par cœur de processeur).
-Envisager l'utilisation de la [sipHash64](#hash_functions-siphash64) la fonction la place.
-
-**Paramètre**
-
-La fonction prend un nombre variable de paramètres d'entrée. Les paramètres peuvent être tout de la [types de données pris en charge](../../sql-reference/data-types/index.md).
-
-**Valeur Renvoyée**
-
-A [UInt64](../../sql-reference/data-types/int-uint.md) valeur de hachage du type de données.
-
-**Exemple**
-
-``` sql
-SELECT halfMD5(array('e','x','a'), 'mple', 10, toDateTime('2019-06-15 23:00:00')) AS halfMD5hash, toTypeName(halfMD5hash) AS type

-
-## MD5 {#hash_functions-md5}
-
-Calcule le MD5 à partir d'une chaîne et renvoie L'ensemble d'octets résultant en tant que FixedString(16).
-Si vous n'avez pas besoin de MD5 en particulier, mais que vous avez besoin d'un hachage cryptographique 128 bits décent, utilisez le ‘sipHash128’ la fonction la place.
-Si vous voulez obtenir le même résultat que la sortie de l'utilitaire md5sum, utilisez lower (hex(MD5 (s))).
-
-## sipHash64 {#hash_functions-siphash64}
-
-Produit un 64 bits [SipHash](https://131002.net/siphash/) la valeur de hachage.
-
-``` sql
-sipHash64(par1,...)
-```
-
-C'est une fonction de hachage cryptographique. Il fonctionne au moins trois fois plus vite que le [MD5](#hash_functions-md5) fonction.
-
-Fonction [interpréter](../../sql-reference/functions/type-conversion-functions.md#type_conversion_functions-reinterpretAsString) tous les paramètres d'entrée sous forme de chaînes et calcule la valeur de hachage pour chacun d'eux. Puis combine les hachages par l'algorithme suivant:
-
-1.  Après avoir haché tous les paramètres d'entrée, la fonction obtient le tableau de hachages.
-2.  La fonction prend le premier et le second éléments et calcule un hachage pour le tableau d'entre eux.
-3.  Ensuite, la fonction prend la valeur de hachage, calculée à l'étape précédente, et le troisième élément du tableau de hachage initial, et calcule un hachage pour le tableau d'entre eux.
-4.  L'étape précédente est répétée pour tous les éléments restants de la période initiale de hachage tableau.
-
-**Paramètre**
-
-La fonction prend un nombre variable de paramètres d'entrée. Les paramètres peuvent être tout de la [types de données pris en charge](../../sql-reference/data-types/index.md).

-
-## sipHash128 {#hash_functions-siphash128}
-
-Calcule SipHash à partir d'une chaîne.
-Accepte un argument de type chaîne. Renvoie FixedString (16).
-Diffère de sipHash64 en ce que l'état de pliage xor final n'est effectué que jusqu'à 128 bits.
-
-## cityHash64 {#cityhash64}
-
-Produit un 64 bits [CityHash](https://github.com/google/cityhash) la valeur de hachage.
-
-``` sql
-cityHash64(par1,...)
-```
-
-Ceci est une fonction de hachage non cryptographique rapide. Il utilise L'algorithme CityHash pour les paramètres de chaîne et la fonction de hachage rapide non cryptographique spécifique à l'implémentation pour les paramètres avec d'autres types de données. La fonction utilise le combinateur CityHash pour obtenir les résultats finaux.
-
-**Paramètre**
-
-La fonction prend un nombre variable de paramètres d'entrée. Les paramètres peuvent être tout de la [types de données pris en charge](../../sql-reference/data-types/index.md).
-
-**Valeur Renvoyée**
-
-A [UInt64](../../sql-reference/data-types/int-uint.md) valeur de hachage du type de données.
-
-**Exemple**
-
-Appelez exemple:
-
-``` sql
-SELECT cityHash64(array('e','x','a'), 'mple', 10, toDateTime('2019-06-15 23:00:00')) AS CityHash, toTypeName(CityHash) AS type

-┌─────────────CityHash─┬─type───┐
-│ 12072650598913549138 │ UInt64 │
-└──────────────────────┴────────┘
-```
-
-L'exemple suivant montre comment calculer la somme de l'ensemble de la table avec précision jusqu'à la ligne de commande:
-
-``` sql
-SELECT groupBitXor(cityHash64(*)) FROM table
-```
-
-## intHash32 {#inthash32}
-
-Calcule un code de hachage 32 bits à partir de n'importe quel type d'entier.
-C'est une fonction de hachage non cryptographique relativement rapide de qualité moyenne pour les nombres.
-
-## intHash64 {#inthash64}
-
-Calcule un code de hachage 64 bits à partir de n'importe quel type d'entier.
-Il fonctionne plus vite que intHash32. Qualité moyenne.
-
-## SHA1 {#sha1}
-
-## SHA224 {#sha224}
-
-## SHA256 {#sha256}
-
-Calcule SHA-1, SHA-224 ou SHA-256 à partir d'une chaîne et renvoie l'ensemble d'octets résultant en tant que FixedString(20), FixedString(28) ou FixedString(32).
-La fonction fonctionne assez lentement (SHA-1 traite environ 5 millions de chaînes courtes par seconde par cœur de processeur, tandis que SHA-224 et SHA-256 traitent environ 2,2 millions).
-Nous vous recommandons d'utiliser cette fonction uniquement dans les cas où vous avez besoin d'une fonction de hachage spécifique et que vous ne pouvez pas la sélectionner.
-Même dans ces cas, nous vous recommandons d'appliquer la fonction hors ligne et de pré-calculer les valeurs lors de leur insertion dans la table, au lieu de l'appliquer dans SELECTS.
-
-## URLHash(url \[, N\]) {#urlhashurl-n}
-
-Une fonction de hachage non cryptographique rapide et de qualité décente pour une chaîne obtenue à partir d'une URL en utilisant un type de normalisation.
-`URLHash(s)` – Calculates a hash from a string without one of the trailing symbols `/`,`?` ou `#` à la fin, si elle est présente.
-`URLHash(s, N)` – Calculates a hash from a string up to the N level in the URL hierarchy, without one of the trailing symbols `/`,`?` ou `#` à la fin, si elle est présente.
-Les niveaux sont les mêmes que dans URLHierarchy. Cette fonction est spécifique à Yandex.Metrica.

-# Fonctions d'ordre supérieur {#higher-order-functions}
-
-## `->` opérateur, fonction lambda (params, expr) {#operator-lambdaparams-expr-function}
-
-Allows describing a lambda function for passing to a higher-order function. The left side of the arrow has a formal parameter, which is any ID, or multiple formal parameters – any IDs in a tuple. The right side of the arrow has an expression that can use these formal parameters, as well as any table columns.
-
-Exemple: `x -> 2 * x, str -> str != Referer.`
-
-Les fonctions d'ordre supérieur ne peuvent accepter que les fonctions lambda comme argument fonctionnel.
-
-Une fonction lambda qui accepte plusieurs arguments peuvent être passés à une fonction d'ordre supérieur. Dans ce cas, la fonction d'ordre supérieur est passé plusieurs tableaux de longueur identique que ces arguments correspondent.
-
-Pour certaines fonctions, telles que [arrayCount](#higher_order_functions-array-count) ou [arraySum](#higher_order_functions-array-count) le premier argument (la fonction lambda) peut être omis. Dans ce cas, un mappage identique est supposé.
-
-Une fonction lambda ne peut pas être omise pour les fonctions suivantes:
-
--   [arrayMap](#higher_order_functions-array-map)
--   [arrayFilter](#higher_order_functions-array-filter)
--   [arrayFill](#higher_order_functions-array-fill)
--   [arrayReverseFill](#higher_order_functions-array-reverse-fill)
--   [arraySplit](#higher_order_functions-array-split)

-SELECT arrayMap(x -> (x + 2), [1, 2, 3]) as res;
-```
-
-``` text
-┌─res─────┐

-```
-
-``` text
-┌─res─────────────────┐

-```
-
-Notez que le premier argument (fonction lambda) ne peut pas être omis dans le `arrayMap` fonction.
-
-### arrayFilter(func, arr1, …) {#higher_order_functions-array-filter}
-
-Renvoie un tableau contenant uniquement les éléments `arr1` pour ce qui `func` retourne autre chose que 0.
-
-Exemple:

-Notez que le premier argument (fonction lambda) ne peut pas être omis dans le `arrayFilter` fonction.
-
-### arrayFill(func, arr1, …) {#higher_order_functions-array-fill}
-
-Analyse par le biais de `arr1` du premier élément au dernier élément et remplacer `arr1[i]` par `arr1[i - 1]` si `func` renvoie 0. Le premier élément de `arr1` ne sera pas remplacé.
-
-Exemple:
-
-``` sql
-SELECT arrayFill(x -> not isNull(x), [1, null, 3, 11, 12, null, null, 5, 6, 14, null, null]) AS res

-
-### arraySplit(func, arr1, …) {#higher_order_functions-array-split}
-
-Split `arr1` en plusieurs tableaux. Lorsque `func` retourne autre chose que 0, la matrice sera de split sur le côté gauche de l'élément. Le tableau ne sera pas partagé avant le premier élément.
-
-Exemple:
-
-``` sql
-SELECT arraySplit((x, y) -> y, [1, 2, 3, 4, 5], [1, 0, 0, 1, 0]) AS res
-```
-
-``` text

-```
-
-Notez que le premier argument (fonction lambda) ne peut pas être omis dans le `arraySplit` fonction.
-
-### arrayReverseSplit(func, arr1, …) {#higher_order_functions-array-reverse-split}
-
-Split `arr1` en plusieurs tableaux. Lorsque `func` retourne autre chose que 0, la matrice sera de split sur le côté droit de l'élément. Le tableau ne sera pas divisé après le dernier élément.
-
-Exemple:
-
-``` sql
-SELECT arrayReverseSplit((x, y) -> y, [1, 2, 3, 4, 5], [1, 0, 0, 1, 0]) AS res
-```
-
-``` text
-┌─res───────────────┐
-│ [[1],[2,3,4],[5]] │

-```
-
-Notez que le premier argument (fonction lambda) ne peut pas être omis dans le `arraySplit` fonction.
-
-### arrayCount(\[func,\] arr1, …) {#higher_order_functions-array-count}
-
-Renvoie le nombre d'éléments dans l'arr tableau pour lequel func renvoie autre chose que 0. Si ‘func’ n'est pas spécifié, il renvoie le nombre d'éléments non nuls dans le tableau.
-
-### arrayExists(\[func,\] arr1, …) {#arrayexistsfunc-arr1}
-
-Renvoie 1 s'il existe au moins un élément ‘arr’ pour ce qui ‘func’ retourne autre chose que 0. Sinon, il renvoie 0.
-
-### arrayAll(\[func,\] arr1, …) {#arrayallfunc-arr1}
-
-Renvoie 1 si ‘func’ retourne autre chose que 0 pour tous les éléments de ‘arr’. Sinon, il renvoie 0.
-
-### arraySum(\[func,\] arr1, …) {#higher-order-functions-array-sum}
-
-Renvoie la somme de la ‘func’ valeur. Si la fonction est omise, elle retourne la somme des éléments du tableau.
-
-### arrayFirst(func, arr1, …) {#higher_order_functions-array-first}
-
-Renvoie le premier élément du ‘arr1’ tableau pour lequel ‘func’ retourne autre chose que 0.
-
-Notez que le premier argument (fonction lambda) ne peut pas être omis dans le `arrayFirst` fonction.
-
-### arrayFirstIndex(func, arr1, …) {#higher_order_functions-array-first-index}
-
-Renvoie l'index du premier élément de la ‘arr1’ tableau pour lequel ‘func’ retourne autre chose que 0.
-
-Notez que le premier argument (fonction lambda) ne peut pas être omis dans le `arrayFirstIndex` fonction.
-
-### arrayCumSum(\[func,\] arr1, …) {#arraycumsumfunc-arr1}
-
-Retourne un tableau des sommes partielles d'éléments dans le tableau source (une somme). Si l' `func` la fonction est spécifiée, les valeurs des éléments du tableau sont convertis par cette fonction avant l'addition.
-
-Exemple:
-
-``` sql
-SELECT arrayCumSum([1, 1, 1, 1]) AS res
-```
-
-``` text
-┌─res──────────┐
-│ [1, 2, 3, 4] │
-└──────────────┘
-```
-
-### arrayCumSumNonNegative (arr) {#arraycumsumnonnegativearr}
-
-Même que `arrayCumSum`, renvoie un tableau des sommes partielles d'éléments dans le tableau source (une somme). Différent `arrayCumSum`, lorsque la valeur renvoyée contient une valeur inférieure à zéro, la valeur est remplacée par zéro et le calcul ultérieur est effectué avec des paramètres zéro. Exemple:
-
-``` sql
-SELECT arrayCumSumNonNegative([1, 1, -4, 1]) AS res
-```
-
-``` text
-┌─res───────┐
-│ [1,2,0,1] │
-└───────────┘
-```
-
-### arraySort(\[func,\] arr1, …) {#arraysortfunc-arr1}
-
-Renvoie un tableau à la suite du tri des éléments de `arr1` dans l'ordre croissant. Si l' `func` la fonction est spécifiée, l'ordre de classement est déterminé par le résultat de la fonction `func` appliquée aux éléments du tableau (tableaux)
-
-Le [Transformation schwartzienne](https://en.wikipedia.org/wiki/Schwartzian_transform) est utilisé pour améliorer l'efficacité du tri.
-
-Exemple:
-
-``` sql
-SELECT arraySort((x, y) -> y, ['hello', 'world'], [2, 1]);
-```
-
-``` text
-┌─res────────────────┐
-│ ['world', 'hello'] │
-└────────────────────┘
-```

-
-### arrayReverseSort(\[func,\] arr1, …) {#arrayreversesortfunc-arr1}
-
-Renvoie un tableau à la suite du tri des éléments de `arr1` dans l'ordre décroissant. Si l' `func` la fonction est spécifiée, l'ordre de classement est déterminé par le résultat de la fonction `func` appliquée aux éléments du tableau (tableaux).
-
-Exemple:
-

----

-# Fonction {#functions}
-
-Il y a au moins\* deux types de fonctions - des fonctions régulières (elles sont simplement appelées “functions”) and aggregate functions. These are completely different concepts. Regular functions work as if they are applied to each row separately (for each row, the result of the function doesn't depend on the other rows). Aggregate functions accumulate a set of values from various rows (i.e. they depend on the entire set of rows).
-
-Dans cette section, nous discutons des fonctions classiques. Pour les fonctions d'agrégation, voir la section “Aggregate functions”.
-
-\* - Il existe un troisième type de fonction ‘arrayJoin’ la fonction appartient à; les fonctions de table peuvent également être mentionnées séparément.\*
-
-## Typage Fort {#strong-typing}
-
-Contrairement à SQL standard, ClickHouse a une forte typage. En d'autres termes, il ne fait pas de conversions implicites entre les types. Chaque fonction fonctionne pour un ensemble spécifique de types. Cela signifie que vous devez parfois utiliser des fonctions de conversion de type.
-
-## Élimination Des Sous-Expressions Courantes {#common-subexpression-elimination}
-
-Toutes les expressions d'une requête qui ont le même AST (le même enregistrement ou le même résultat d'analyse syntaxique) sont considérées comme ayant des valeurs identiques. De telles expressions sont concaténées et exécutées une fois. Les sous-requêtes identiques sont également éliminées de cette façon.
-
-## Types de résultats {#types-of-results}
-
-Toutes les fonctions renvoient un seul retour comme résultat (pas plusieurs valeurs, et pas des valeurs nulles). Le type de résultat est généralement défini uniquement par les types d'arguments, pas par les valeurs. Les Exceptions sont la fonction tupleElement (l'opérateur A. N) et la fonction toFixedString.
-
-## Constant {#constants}
-
-Pour simplifier, certaines fonctions ne peuvent fonctionner qu'avec des constantes pour certains arguments. Par exemple, le bon argument de L'opérateur LIKE doit être une constante.
-Presque toutes les fonctions renvoient une constante pour des arguments constants. L'exception est les fonctions qui génèrent des nombres aléatoires.
-Le ‘now’ function renvoie des valeurs différentes pour les requêtes qui ont été exécutées à des moments différents, mais le résultat est considéré comme une constante, car la constance n'est importante que dans une seule requête.
-Une expression constante est également considérée comme une constante (par exemple, la moitié droite de L'opérateur LIKE peut être construite à partir de plusieurs constantes).
-
-Les fonctions peuvent être implémentées de différentes manières pour des arguments constants et non constants (un code différent est exécuté). Mais les résultats pour une constante et pour une colonne vraie Ne contenant que la même valeur doivent correspondre les uns aux autres.
-
-## Le Traitement NULL {#null-processing}
-
-Les fonctions ont les comportements suivants:
-
--   Si au moins l'un des arguments de la fonction est `NULL` le résultat de la fonction est également `NULL`.
--   Comportement spécial spécifié individuellement dans la description de chaque fonction. Dans le code source de ClickHouse, ces fonctions ont `UseDefaultImplementationForNulls=false`.
-
-## Constance {#constancy}
-
-Functions can't change the values of their arguments – any changes are returned as the result. Thus, the result of calculating separate functions does not depend on the order in which the functions are written in the query.
-
-## Erreur De Manipulation {#error-handling}
-
-Certaines fonctions peuvent lancer une exception si les données ne sont pas valides. Dans ce cas, la requête est annulée et un message d'erreur est retourné au client. Pour le traitement distribué, lorsqu'une exception se produit sur l'un des serveurs, les autres serveurs aussi tenté d'interrompre la requête.
-
-## Évaluation des Expressions D'Argument {#evaluation-of-argument-expressions}
-
-Dans presque tous les langages de programmation, l'un des arguments peut pas être évalué pour certains opérateurs. Ce sont généralement les opérateurs `&&`, `||`, et `?:`.
-Mais dans ClickHouse, les arguments des fonctions (opérateurs) sont toujours évalués. En effet, des parties entières de colonnes sont évaluées à la fois, au lieu de calculer chaque ligne séparément.
-
-## Exécution de fonctions pour le traitement de requêtes distribuées {#performing-functions-for-distributed-query-processing}
-
-Pour le traitement de requête distribué, autant d'étapes de traitement de requête que possible sont effectuées sur des serveurs distants, et le reste des étapes (fusion des résultats intermédiaires et tout ce qui suit) sont effectuées sur le serveur demandeur.
-
-Cela signifie que les fonctions peuvent être effectuées sur différents serveurs.
-Par exemple, dans la requête `SELECT f(sum(g(x))) FROM distributed_table GROUP BY h(y),`
-
--   si un `distributed_table` a au moins deux fragments, les fonctions ‘g’ et ‘h’ sont effectuées sur des serveurs distants, et la fonction ‘f’ est effectuée sur le serveur demandeur.
--   si un `distributed_table` a un seul fragment, tous les ‘f’, ‘g’, et ‘h’ les fonctions sont exécutées sur le serveur de ce fragment.
-
-Le résultat d'une fonction habituellement ne dépendent pas le serveur sur lequel elle est exécutée. Cependant, parfois c'est important.
-Par exemple, les fonctions qui fonctionnent avec des dictionnaires utilisent le dictionnaire qui existe sur le serveur sur lequel elles s'exécutent.
-Un autre exemple est l' `hostName` fonction, qui renvoie le nom du serveur sur lequel il s'exécute afin de `GROUP BY` par les serveurs dans un `SELECT` requête.
-
-Si une fonction dans une requête est effectuée sur le demandeur serveur, mais vous devez l'exécuter sur des serveurs distants, vous pouvez l'envelopper dans un ‘any’ fonction d'agrégation ou l'ajouter à une clé dans `GROUP BY`.

-toc_title: Travailler avec JSON
----
-
-# Fonctions pour travailler avec JSON {#functions-for-working-with-json}
-
-Dans Yandex.Metrica, JSON est transmis par les utilisateurs en tant que paramètres de session. Il y a quelques fonctions spéciales pour travailler avec ce JSON. (Bien que dans la plupart des cas, les JSONs soient en outre prétraités et les valeurs résultantes sont placées dans des colonnes séparées dans leur format traité.) Toutes ces fonctions sont basées sur des hypothèses fortes sur ce que le JSON peut être, mais elles essaient de faire le moins possible pour faire le travail.
-
-Les hypothèses suivantes sont apportées:
-
-1.  Le nom du champ (argument de fonction) doit être une constante.
-2.  Le nom du champ est en quelque sorte codé canoniquement dans JSON. Exemple: `visitParamHas('{"abc":"def"}', 'abc') = 1`, mais `visitParamHas('{"\\u0061\\u0062\\u0063":"def"}', 'abc') = 0`
-3.  Les champs sont recherchés à n'importe quel niveau d'imbrication, sans discrimination. S'il y a plusieurs champs correspondants, la première occurrence est utilisé.
-4.  Le JSON n'a pas de caractères d'espace en dehors des littéraux de chaîne.
-
-## visitParamHas(params, nom) {#visitparamhasparams-name}
-
-Vérifie s'il existe un champ avec ‘name’ nom.
-
-## visitParamExtractUInt(params, nom) {#visitparamextractuintparams-name}
-
-Analyse UInt64 à partir de la valeur du champ nommé ‘name’. Si c'est un champ de type chaîne, il tente d'analyser un numéro à partir du début de la chaîne. Si le champ n'existe pas, ou s'il existe mais ne contient pas de nombre, il renvoie 0.
-
-## visitParamExtractInt(params, name) {#visitparamextractintparams-name}
-
-Le même que pour Int64.
-
-## visitParamExtractFloat(params, nom) {#visitparamextractfloatparams-name}
-
-Le même que pour Float64.
-
-## visitParamExtractBool(params, nom) {#visitparamextractboolparams-name}
-
-Analyse d'une valeur vrai/faux. Le résultat est UInt8.
-
-## visitParamExtractRaw(params, nom) {#visitparamextractrawparams-name}
-
-Retourne la valeur d'un champ, y compris les séparateurs.
-
-Exemple:
-
-``` sql
-visitParamExtractRaw('{"abc":"\\n\\u0000"}', 'abc') = '"\\n\\u0000"'
-visitParamExtractRaw('{"abc":{"def":[1,2,3]}}', 'abc') = '{"def":[1,2,3]}'
-```
-
-## visitParamExtractString(params, nom) {#visitparamextractstringparams-name}
-
-Analyse la chaîne entre guillemets doubles. La valeur est sans échappement. Si l'échappement échoue, il renvoie une chaîne vide.
-
-Exemple:
-
-``` sql
-visitParamExtractString('{"abc":"\\n\\u0000"}', 'abc') = '\n\0'
-visitParamExtractString('{"abc":"\\u263a"}', 'abc') = '☺'
-visitParamExtractString('{"abc":"\\u263"}', 'abc') = ''
-visitParamExtractString('{"abc":"hello}', 'abc') = ''
-```
-
-Il n'y a actuellement aucun support pour les points de code dans le format `\uXXXX\uYYYY` qui ne proviennent pas du plan multilingue de base (ils sont convertis en CESU-8 au lieu de UTF-8).
-
-Les fonctions suivantes sont basées sur [simdjson](https://github.com/lemire/simdjson) conçu pour des exigences D'analyse JSON plus complexes. L'hypothèse 2 mentionnée ci-dessus s'applique toujours.
-
-## isValidJSON (json) {#isvalidjsonjson}
-
-Vérifie que la chaîne est un json valide.
-
-Exemple:
-
-``` sql
-SELECT isValidJSON('{"a": "hello", "b": [-100, 200.0, 300]}') = 1
-SELECT isValidJSON('not a json') = 0
-```
-
-## JSONHas(json\[, indices_or_keys\]…) {#jsonhasjson-indices-or-keys}
-
-Si la valeur existe dans le document JSON, `1` sera retourné.
-
-Si la valeur n'existe pas, `0` sera retourné.
-
-Exemple:
-
-``` sql
-SELECT JSONHas('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = 1
-SELECT JSONHas('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 4) = 0
-```
-
-`indices_or_keys` est une liste de zéro ou plusieurs arguments chacun d'entre eux peut être une chaîne ou un entier.
-
--   String = membre d'objet d'accès par clé.
--   Entier positif = accédez au n-ème membre / clé depuis le début.
--   Entier négatif = accédez au n-ème membre / clé à partir de la fin.
-
-Minimum de l'indice de l'élément est 1. Ainsi, l'élément 0 n'existe pas.
-
-Vous pouvez utiliser des entiers pour accéder à la fois aux tableaux JSON et aux objets JSON.
-
-Ainsi, par exemple:
-
-``` sql
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', 1) = 'a'
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', 2) = 'b'
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', -1) = 'b'
-SELECT JSONExtractKey('{"a": "hello", "b": [-100, 200.0, 300]}', -2) = 'a'
-SELECT JSONExtractString('{"a": "hello", "b": [-100, 200.0, 300]}', 1) = 'hello'
-```
-
-## JSONLength(json\[, indices_or_keys\]…) {#jsonlengthjson-indices-or-keys}
-
-Renvoie la longueur D'un tableau JSON ou d'un objet JSON.
-
-Si la valeur n'existe pas ou a un mauvais type, `0` sera retourné.
-
-Exemple:
-
-``` sql
-SELECT JSONLength('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = 3
-SELECT JSONLength('{"a": "hello", "b": [-100, 200.0, 300]}') = 2
-```
-
-## JSONType(json\[, indices_or_keys\]…) {#jsontypejson-indices-or-keys}
-
-De retour le type d'une valeur JSON.
-
-Si la valeur n'existe pas, `Null` sera retourné.
-
-Exemple:
-
-``` sql
-SELECT JSONType('{"a": "hello", "b": [-100, 200.0, 300]}') = 'Object'
-SELECT JSONType('{"a": "hello", "b": [-100, 200.0, 300]}', 'a') = 'String'
-SELECT JSONType('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = 'Array'
-```
-
-## JSONExtractUInt(json\[, indices_or_keys\]…) {#jsonextractuintjson-indices-or-keys}
-
-## JSONExtractInt(json\[, indices_or_keys\]…) {#jsonextractintjson-indices-or-keys}
-
-## JSONExtractFloat(json\[, indices_or_keys\]…) {#jsonextractfloatjson-indices-or-keys}
-
-## JSONExtractBool(json\[, indices_or_keys\]…) {#jsonextractbooljson-indices-or-keys}
-
-Analyse un JSON et extrait une valeur. Ces fonctions sont similaires à `visitParam` fonction.
-
-Si la valeur n'existe pas ou a un mauvais type, `0` sera retourné.
-
-Exemple:
-
-``` sql
-SELECT JSONExtractInt('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 1) = -100
-SELECT JSONExtractFloat('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 2) = 200.0
-SELECT JSONExtractUInt('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', -1) = 300
-```
-
-## JSONExtractString(json\[, indices_or_keys\]…) {#jsonextractstringjson-indices-or-keys}
-
-Analyse un JSON et extrait une chaîne. Cette fonction est similaire à `visitParamExtractString` fonction.
-
-Si la valeur n'existe pas ou a un mauvais type, une chaîne vide est retournée.
-
-La valeur est sans échappement. Si l'échappement échoue, il renvoie une chaîne vide.
-
-Exemple:
-
-``` sql
-SELECT JSONExtractString('{"a": "hello", "b": [-100, 200.0, 300]}', 'a') = 'hello'
-SELECT JSONExtractString('{"abc":"\\n\\u0000"}', 'abc') = '\n\0'
-SELECT JSONExtractString('{"abc":"\\u263a"}', 'abc') = '☺'
-SELECT JSONExtractString('{"abc":"\\u263"}', 'abc') = ''
-SELECT JSONExtractString('{"abc":"hello}', 'abc') = ''
-```
-
-## JSONExtract(json\[, indices_or_keys…\], Return_type) {#jsonextractjson-indices-or-keys-return-type}
-
-Analyse un JSON et extrait une valeur du type de données clickhouse donné.
-
-C'est une généralisation de la précédente `JSONExtract<type>` fonction.
-Cela signifie
-`JSONExtract(..., 'String')` retourne exactement le même que `JSONExtractString()`,
-`JSONExtract(..., 'Float64')` retourne exactement le même que `JSONExtractFloat()`.
-
-Exemple:
-
-``` sql
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'Tuple(String, Array(Float64))') = ('hello',[-100,200,300])
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'Tuple(b Array(Float64), a String)') = ([-100,200,300],'hello')
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 'Array(Nullable(Int8))') = [-100, NULL, NULL]
-SELECT JSONExtract('{"a": "hello", "b": [-100, 200.0, 300]}', 'b', 4, 'Nullable(Int64)') = NULL
-SELECT JSONExtract('{"passed": true}', 'passed', 'UInt8') = 1
-SELECT JSONExtract('{"day": "Thursday"}', 'day', 'Enum8(\'Sunday\' = 0, \'Monday\' = 1, \'Tuesday\' = 2, \'Wednesday\' = 3, \'Thursday\' = 4, \'Friday\' = 5, \'Saturday\' = 6)') = 'Thursday'
-SELECT JSONExtract('{"day": 5}', 'day', 'Enum8(\'Sunday\' = 0, \'Monday\' = 1, \'Tuesday\' = 2, \'Wednesday\' = 3, \'Thursday\' = 4, \'Friday\' = 5, \'Saturday\' = 6)') = 'Friday'
-```
-
-## JSONExtractKeysAndValues(json\[, indices_or_keys…\], Value_type) {#jsonextractkeysandvaluesjson-indices-or-keys-value-type}
-
-Analyse les paires clé-valeur à partir D'un JSON où les valeurs sont du type de données clickhouse donné.
-
-Exemple:
-
-``` sql
-SELECT JSONExtractKeysAndValues('{"x": {"a": 5, "b": 7, "c": 11}}', 'x', 'Int8') = [('a',5),('b',7),('c',11)]
-```
-
-## JSONExtractRaw(json\[, indices_or_keys\]…) {#jsonextractrawjson-indices-or-keys}
-
-Renvoie une partie de JSON en tant que chaîne non analysée.
-
-Si la pièce n'existe pas ou a un mauvais type, une chaîne vide est retournée.
-
-Exemple:
-
-``` sql
-SELECT JSONExtractRaw('{"a": "hello", "b": [-100, 200.0, 300]}', 'b') = '[-100, 200.0, 300]'
-```
-
-## JSONExtractArrayRaw(json\[, indices_or_keys…\]) {#jsonextractarrayrawjson-indices-or-keys}
-
-Retourne un tableau avec des éléments de tableau JSON, chacun représenté comme une chaîne non analysée.
-
-Si la pièce n'existe pas ou n'est pas de tableau, un tableau vide sera retournée.
-
-Exemple:
-
-``` sql
-SELECT JSONExtractArrayRaw('{"a": "hello", "b": [-100, 200.0, "hello"]}', 'b') = ['-100', '200.0', '"hello"']'
-```
-
-## JSONExtractKeysAndValuesRaw {#json-extract-keys-and-values-raw}
-
-Extrait les données brutes d'un objet JSON.
-
-**Syntaxe**

-## transformer {#transform}
-
-Transforme une valeur en fonction explicitement définis cartographie de certains éléments à l'autre.
-Il existe deux variantes de cette fonction:
-
-### de transformation(x, array_from, array_to, par défaut) {#transformx-array-from-array-to-default}
-
-`x` – What to transform.
-
-`array_from` – Constant array of values for converting.
-
-`array_to` – Constant array of values to convert the values in ‘from’ de.
-
-`default` – Which value to use if ‘x’ n'est pas égale à une des valeurs de ‘from’.
-
-`array_from` et `array_to` – Arrays of the same size.
-
-Type:
-
-`transform(T, Array(T), Array(U), U) -> U`
-
-`T` et `U` peuvent être des types numériques, chaîne ou Date ou DateTime.
-Lorsque la même lettre est indiquée (T ou U), pour les types numériques, il se peut qu'il ne s'agisse pas de types correspondants, mais de types ayant un type commun.
-Par exemple, le premier argument peut avoir le type Int64, tandis que le second a le type Array(UInt16).
-
-Si l' ‘x’ la valeur est égale à l'un des éléments dans la ‘array_from’ tableau, elle renvoie l'élément existant (qui est numéroté de même) de la ‘array_to’ tableau. Sinon, elle renvoie ‘default’. S'il y a plusieurs éléments correspondants dans ‘array_from’ il renvoie l'un des matches.
-
-Exemple:
-
-``` sql
-SELECT
-    transform(SearchEngineID, [2, 3], ['Yandex', 'Google'], 'Other') AS title,
-    count() AS c
-FROM test.hits
-WHERE SearchEngineID != 0
-GROUP BY title
-ORDER BY c DESC

-└───────────┴────────┘
-```
-
-### de transformation(x, array_from, array_to) {#transformx-array-from-array-to}
-
-Diffère de la première variation en ce que le ‘default’ l'argument est omis.
-Si l' ‘x’ la valeur est égale à l'un des éléments dans la ‘array_from’ tableau, elle renvoie l'élément correspondant (qui est numéroté de même) de la ‘array_to’ tableau. Sinon, elle renvoie ‘x’.
-
-Type:
-
-`transform(T, Array(T), Array(T)) -> T`
-
-Exemple:
-
-``` sql
-SELECT
-    transform(domain(Referer), ['yandex.ru', 'google.ru', 'vk.com'], ['www.yandex', 'example.com']) AS s,
-    count() AS c
-FROM test.hits
-GROUP BY domain(Referer)
-ORDER BY count() DESC
-LIMIT 10

-# Fonctions pour générer des nombres Pseudo-aléatoires {#functions-for-generating-pseudo-random-numbers}
-
-Des générateurs Non cryptographiques de nombres pseudo-aléatoires sont utilisés.
-
-Toutes les fonctions acceptent zéro argument ou un argument.
-Si un argument est passé, il peut être de n'importe quel type, et sa valeur n'est utilisée pour rien.
-Le seul but de cet argument est d'empêcher l'élimination des sous-expressions courantes, de sorte que deux instances différentes de la même fonction renvoient des colonnes différentes avec des nombres aléatoires différents.

-**Paramètre**
-
--   `x` — [Expression](../syntax.md#syntax-expressions) résultant de la [types de données pris en charge](../data-types/index.md#data_types). La valeur résultante est ignorée, mais l'expression elle-même si elle est utilisée pour contourner [élimination des sous-expressions courantes](index.md#common-subexpression-elimination) si la fonction est appelée plusieurs fois dans une seule requête.

----
-
-# Fonctions D'Arrondi {#rounding-functions}
-
-## floor(x\[, N\]) {#floorx-n}
-
-Renvoie le plus grand nombre rond inférieur ou égal à `x`. Un nombre rond est un multiple de 1 / 10N, ou le nombre le plus proche du type de données approprié si 1 / 10N n'est pas exact.
-‘N’ est une constante entière, paramètre facultatif. Par défaut, il est zéro, ce qui signifie arrondir à un entier.
-‘N’ peut être négative.
-
-Exemple: `floor(123.45, 1) = 123.4, floor(123.45, -1) = 120.`
-
-`x` est n'importe quel type numérique. Le résultat est un nombre du même type.
-Pour les arguments entiers, il est logique d'arrondir avec un négatif `N` valeur (pour non négatif `N`, la fonction ne fait rien).
-Si l'arrondi provoque un débordement (par exemple, floor(-128, -1)), un résultat spécifique à l'implémentation est renvoyé.
-
-## ceil(x\[, n\]), plafond (x\[, n\]) {#ceilx-n-ceilingx-n}
-
-Renvoie le plus petit nombre rond supérieur ou égal à `x`. Dans tous les autres sens, il est le même que le `floor` fonction (voir ci-dessus).
-
-## trunc(x \[, N\]), truncate(x \[, N\]) {#truncx-n-truncatex-n}
-
-Renvoie le nombre rond avec la plus grande valeur absolue qui a une valeur absolue inférieure ou égale à `x`‘s. In every other way, it is the same as the ’floor’ fonction (voir ci-dessus).
-
-## round(x\[, N\]) {#rounding_functions-round}
-
-Arrondit une valeur à un nombre spécifié de décimales.
-
-La fonction renvoie le nombre plus proche de l'ordre spécifié. Dans le cas où un nombre donné a une distance égale aux nombres environnants, la fonction utilise l'arrondi de banquier pour les types de nombres flottants et arrondit à partir de zéro pour les autres types de nombres.
-
-``` sql
-round(expression [, decimal_places])
-```
-
-**Paramètre:**
-
--   `expression` — A number to be rounded. Can be any [expression](../syntax.md#syntax-expressions) retour du numérique [type de données](../../sql-reference/data-types/index.md#data_types).
--   `decimal-places` — An integer value.
-    -   Si `decimal-places > 0` alors la fonction arrondit la valeur à droite du point décimal.
-    -   Si `decimal-places < 0` alors la fonction arrondit la valeur à gauche de la virgule décimale.
-    -   Si `decimal-places = 0` alors la fonction arrondit la valeur à l'entier. Dans ce cas, l'argument peut être omis.
-
-**Valeur renvoyée:**
-
-Le nombre arrondi du même type que le nombre d'entrée.
-
-### Exemple {#examples}

-round(4.5) = 4
-round(3.55, 1) = 3.6
-round(3.65, 1) = 3.6
-```
-
-**Voir Aussi**
-
--   [roundBankers](#roundbankers)
-
-## roundBankers {#roundbankers}
-
-Arrondit un nombre à une position décimale spécifiée.
-
--   Si le nombre est arrondi à mi-chemin entre deux nombres, la fonction utilise l'arrondi.
-
-        Banker's rounding is a method of rounding fractional numbers. When the rounding number is halfway between two numbers, it's rounded to the nearest even digit at the specified decimal position. For example: 3.5 rounds up to 4, 2.5 rounds down to 2.
-
-        It's the default rounding method for floating point numbers defined in [IEEE 754](https://en.wikipedia.org/wiki/IEEE_754#Roundings_to_nearest). The [round](#rounding_functions-round) function performs the same rounding for floating point numbers. The `roundBankers` function also rounds integers the same way, for example, `roundBankers(45, -1) = 40`.
-
--   Dans d'autres cas, la fonction arrondit les nombres à l'entier le plus proche.
-
-À l'aide de l'arrondi, vous pouvez réduire l'effet qu'arrondir les nombres sur les résultats d'additionner ou de soustraire ces chiffres.
-
-Par exemple, les nombres de somme 1.5, 2.5, 3.5, 4.5 avec des arrondis différents:
-
--   Pas d'arrondi: 1.5 + 2.5 + 3.5 + 4.5 = 12.
--   Arrondi du banquier: 2 + 2 + 4 + 4 = 12.
--   Arrondi à l'entier le plus proche: 2 + 3 + 4 + 5 = 14.
-
-**Syntaxe**
-
-``` sql
-roundBankers(expression [, decimal_places])
-```
-
-**Paramètre**
-
--   `expression` — A number to be rounded. Can be any [expression](../syntax.md#syntax-expressions) retour du numérique [type de données](../../sql-reference/data-types/index.md#data_types).
--   `decimal-places` — Decimal places. An integer number.
-    -   `decimal-places > 0` — The function rounds the number to the given position right of the decimal point. Example: `roundBankers(3.55, 1) = 3.6`.
-    -   `decimal-places < 0` — The function rounds the number to the given position left of the decimal point. Example: `roundBankers(24.55, -1) = 20`.
-    -   `decimal-places = 0` — The function rounds the number to an integer. In this case the argument can be omitted. Example: `roundBankers(2.5) = 2`.

-## replaceOne(botte de foin, modèle, remplacement) {#replaceonehaystack-pattern-replacement}
-
-Remplace la première occurrence, si elle existe, ‘pattern’ sous-chaîne dans ‘haystack’ avec l' ‘replacement’ substring.
-Ci-après, ‘pattern’ et ‘replacement’ doivent être constantes.
-
-## replaceAll(botte de foin, motif, remplacement), Remplacer(botte de foin, motif, remplacement) {#replaceallhaystack-pattern-replacement-replacehaystack-pattern-replacement}

-Remplacement en utilisant le ‘pattern’ expression régulière. Une expression régulière re2.
-Remplace seulement la première occurrence, si elle existe.
-Un motif peut être spécifié comme ‘replacement’. Ce modèle peut inclure des substitutions `\0-\9`.
-Substitution `\0` inclut l'expression régulière entière. Substitution `\1-\9` correspond au sous-modèle numbers.To utilisez le `\` caractère dans un modèle, échappez-le en utilisant `\`.
-Aussi garder à l'esprit qu'un littéral de chaîne nécessite une évasion.
-
-Exemple 1. Conversion de la date au format américain:
-
-``` sql
-SELECT DISTINCT

-## regexpQuoteMeta (s) {#regexpquotemetas}
-
-La fonction ajoute une barre oblique inverse avant certains caractères prédéfinis dans la chaîne.
-Les personnages prédéfinis: ‘0’, ‘\\’, ‘\|’, ‘(’, ‘)’, ‘^’, ‘$’, ‘.’, ‘\[’, '\]', ‘?’, '\*‘,’+‘,’{‘,’:‘,’-'.
-Cette implémentation diffère légèrement de re2:: RE2:: QuoteMeta. Il échappe à zéro octet comme \\0 au lieu de 00 et il échappe uniquement les caractères requis.
-Pour plus d'informations, voir le lien: [RE2](https://github.com/google/re2/blob/master/re2/re2.cc#L473)

-# Fonctions de recherche de chaînes {#functions-for-searching-strings}
-
-La recherche est sensible à la casse par défaut dans toutes ces fonctions. Il existe des variantes pour la recherche insensible à la casse.
-
-## position(botte de foin, aiguille), localiser( botte de foin, aiguille) {#position}
-
-Renvoie la position (en octets) de la sous-chaîne trouvée dans la chaîne, à partir de 1.
-
-Fonctionne sous l'hypothèse que la chaîne de caractères contient un ensemble d'octets représentant un octet texte codé. Si cette hypothèse n'est pas remplie et qu'un caractère ne peut pas être représenté à l'aide d'un seul octet, la fonction ne lance pas d'exception et renvoie un résultat inattendu. Si le caractère peut être représenté en utilisant deux octets, il utilisera deux octets et ainsi de suite.
-
-Pour une recherche insensible à la casse, utilisez la fonction [positioncaseinsensible](#positioncaseinsensitive).
-
-**Syntaxe**
-
-``` sql
-position(haystack, needle)
-```
-
-Alias: `locate(haystack, needle)`.
-
-**Paramètre**
-
--   `haystack` — string, in which substring will to be searched. [Chaîne](../syntax.md#syntax-string-literal).
--   `needle` — substring to be searched. [Chaîne](../syntax.md#syntax-string-literal).
-
-**Valeurs renvoyées**
-
--   Position de départ en octets (à partir de 1), si la sous-chaîne a été trouvée.
--   0, si la sous-chaîne n'a pas été trouvé.
-
-Type: `Integer`.
-
-**Exemple**
-
-Phrase “Hello, world!” contient un ensemble d'octets représentant un octet texte codé. La fonction renvoie un résultat attendu:
-
-Requête:
-
-``` sql
-SELECT position('Hello, world!', '!')

-
-La même phrase en russe contient des caractères qui ne peuvent pas être représentés en utilisant un seul octet. La fonction renvoie un résultat inattendu (utilisation [positionUTF8](#positionutf8) fonction pour le texte codé sur plusieurs octets):
-
-Requête:

-
-La recherche est effectuée sur des séquences d'octets sans tenir compte de l'encodage et du classement des chaînes.

-## multiSearchAllPositionsUTF8 {#multiSearchAllPositionsUTF8}
-
-Voir `multiSearchAllPositions`.
-
-## multiSearchFirstPosition(botte de foin, \[aiguille<sub>1</sub>, aiguille<sub>2</sub>, …, needle<sub>et</sub>\]) {#multisearchfirstposition}
-
-Le même que `position` mais renvoie le décalage le plus à gauche de la chaîne `haystack` et qui correspond à certains des aiguilles.
-
-Pour une recherche insensible à la casse ou/et au format UTF-8, utilisez les fonctions `multiSearchFirstPositionCaseInsensitive, multiSearchFirstPositionUTF8, multiSearchFirstPositionCaseInsensitiveUTF8`.
-
-## multiSearchFirstIndex(botte de foin, \[aiguille<sub>1</sub>, aiguille<sub>2</sub>, …, needle<sub>et</sub>\]) {#multisearchfirstindexhaystack-needle1-needle2-needlen}
-
-Renvoie l'index `i` (à partir de 1) de l'aiguille trouvée la plus à gauche<sub>je</sub> dans la chaîne `haystack` et 0 sinon.
-
-Pour une recherche insensible à la casse ou/et au format UTF-8, utilisez les fonctions `multiSearchFirstIndexCaseInsensitive, multiSearchFirstIndexUTF8, multiSearchFirstIndexCaseInsensitiveUTF8`.
-
-## multiSearchAny(botte de foin, \[aiguille<sub>1</sub>, aiguille<sub>2</sub>, …, needle<sub>et</sub>\]) {#function-multisearchany}
-
-Renvoie 1, si au moins une aiguille de chaîne<sub>je</sub> correspond à la chaîne `haystack` et 0 sinon.
-
-Pour une recherche insensible à la casse ou/et au format UTF-8, utilisez les fonctions `multiSearchAnyCaseInsensitive, multiSearchAnyUTF8, multiSearchAnyCaseInsensitiveUTF8`.
-
-!!! note "Note"
-    Dans tous les `multiSearch*` fonctions le nombre d'aiguilles doit être d'au moins 2<sup>8</sup> en raison de la spécification de mise en œuvre.
-
-## match (botte de foin, motif) {#matchhaystack-pattern}
-
-Vérifie si la chaîne correspond au `pattern` expression régulière. Un `re2` expression régulière. Le [syntaxe](https://github.com/google/re2/wiki/Syntax) de la `re2` les expressions régulières sont plus limitées que la syntaxe des expressions régulières Perl.
-
-Renvoie 0 si elle ne correspond pas, ou 1 si elle correspond.
-
-Notez que le symbole antislash (`\`) est utilisé pour s'échapper dans l'expression régulière. Le même symbole est utilisé pour échapper dans les littéraux de chaîne. Donc, pour échapper au symbole dans une expression régulière, vous devez écrire deux barres obliques inverses ( \\ ) dans un littéral de chaîne.
-
-L'expression régulière travaille à la chaîne, comme si c'est un ensemble d'octets. L'expression régulière ne peut pas contenir d'octets nuls.
-Pour que les modèles recherchent des sous-chaînes dans une chaîne, il est préférable D'utiliser LIKE ou ‘position’ depuis ils travaillent beaucoup plus vite.
-
-## multiMatchAny(botte de foin, \[motif<sub>1</sub>, modèle<sub>2</sub>, …, pattern<sub>et</sub>\]) {#multimatchanyhaystack-pattern1-pattern2-patternn}
-
-Le même que `match` mais renvoie 0 si aucune des expressions régulières sont appariés et 1 si l'un des modèles les matchs. Il utilise [hyperscan](https://github.com/intel/hyperscan) bibliothèque. Pour que les modèles recherchent des sous-chaînes dans une chaîne, il est préférable d'utiliser `multiSearchAny` comme cela fonctionne beaucoup plus vite.
-
-!!! note "Note"
-    La longueur de l'un des `haystack` la chaîne doit être inférieure à 2<sup>32</sup> octets sinon l'exception est levée. Cette restriction a lieu en raison de l'API hyperscan.
-
-## multiMatchAnyIndex(botte de foin, \[motif<sub>1</sub>, modèle<sub>2</sub>, …, pattern<sub>et</sub>\]) {#multimatchanyindexhaystack-pattern1-pattern2-patternn}
-
-Le même que `multiMatchAny` mais retourne un index qui correspond à la botte de foin.
-
-## multiMatchAllIndices(botte de foin, \[motif<sub>1</sub>, modèle<sub>2</sub>, …, pattern<sub>et</sub>\]) {#multimatchallindiceshaystack-pattern1-pattern2-patternn}
-
-Le même que `multiMatchAny`, mais renvoie le tableau de tous les indices qui correspondent à la botte de foin dans n'importe quel ordre.
-
-## multiFuzzyMatchAny(botte de foin, distance, \[motif<sub>1</sub>, modèle<sub>2</sub>, …, pattern<sub>et</sub>\]) {#multifuzzymatchanyhaystack-distance-pattern1-pattern2-patternn}
-
-Le même que `multiMatchAny`, mais renvoie 1 si un motif correspond à la botte de foin dans une constante [distance d'édition](https://en.wikipedia.org/wiki/Edit_distance). Cette fonction est également en mode expérimental et peut être extrêmement lente. Pour plus d'informations, voir [documentation hyperscan](https://intel.github.io/hyperscan/dev-reference/compilation.html#approximate-matching).
-
-## multiFuzzyMatchAnyIndex(botte de foin, distance, \[motif<sub>1</sub>, modèle<sub>2</sub>, …, pattern<sub>et</sub>\]) {#multifuzzymatchanyindexhaystack-distance-pattern1-pattern2-patternn}
-
-Le même que `multiFuzzyMatchAny`, mais renvoie tout index qui correspond à la botte de foin à une distance d'édition constante.
-
-## multiFuzzyMatchAllIndices(botte de foin, distance, \[motif<sub>1</sub>, modèle<sub>2</sub>, …, pattern<sub>et</sub>\]) {#multifuzzymatchallindiceshaystack-distance-pattern1-pattern2-patternn}
-
-Le même que `multiFuzzyMatchAny`, mais renvoie le tableau de tous les indices dans n'importe quel ordre qui correspond à la botte de foin à une distance d'édition constante.
-
-!!! note "Note"
-    `multiFuzzyMatch*` les fonctions ne prennent pas en charge les expressions régulières UTF-8, et ces expressions sont traitées comme des octets en raison de la restriction hyperscan.
-
-!!! note "Note"
-    Pour désactiver toutes les fonctions qui utilisent hyperscan, utilisez le réglage `SET allow_hyperscan = 0;`.
-
-## extrait(botte de foin, motif) {#extracthaystack-pattern}
-
-Extraits d'un fragment d'une chaîne à l'aide d'une expression régulière. Si ‘haystack’ ne correspond pas à l' ‘pattern’ regex, une chaîne vide est renvoyée. Si l'expression rationnelle ne contient pas de sous-modèles, elle prend le fragment qui correspond à l'expression rationnelle entière. Sinon, il prend le fragment qui correspond au premier sous-masque.
-
-## extractAll(botte de foin, motif) {#extractallhaystack-pattern}
-
-Extrait tous les fragments d'une chaîne à l'aide d'une expression régulière. Si ‘haystack’ ne correspond pas à l' ‘pattern’ regex, une chaîne vide est renvoyée. Renvoie un tableau de chaînes composé de toutes les correspondances à l'expression rationnelle. En général, le comportement est le même que le ‘extract’ fonction (il prend le premier sous-masque, ou l'expression entière s'il n'y a pas de sous-masque).
-
-## comme (botte de foin, motif), botte de foin comme opérateur de motif {#function-like}
-
-Vérifie si une chaîne correspond à une expression régulière simple.
-L'expression régulière peut contenir les métasymboles `%` et `_`.
-
-`%` indique n'importe quelle quantité d'octets (y compris zéro caractère).
-
-`_` indique un octet.
-
-Utilisez la barre oblique inverse (`\`) pour échapper aux métasymboles. Voir la note sur l'échappement dans la description du ‘match’ fonction.
-
-Pour les expressions régulières comme `%needle%`, le code est plus optimale et fonctionne aussi vite que le `position` fonction.
-Pour d'autres expressions régulières, le code est le même que pour la ‘match’ fonction.
-
-## notLike (botte de foin, motif), botte de foin pas comme opérateur de motif {#function-notlike}
-
-La même chose que ‘like’ mais négative.
-
-## ngramDistance(botte de foin, aiguille) {#ngramdistancehaystack-needle}
-
-Calcule la distance de 4 grammes entre `haystack` et `needle`: counts the symmetric difference between two multisets of 4-grams and normalizes it by the sum of their cardinalities. Returns float number from 0 to 1 – the closer to zero, the more strings are similar to each other. If the constant `needle` ou `haystack` est plus de 32Kb, jette une exception. Si une partie de la non-constante `haystack` ou `needle` les chaînes sont plus que 32Kb, la distance est toujours un.
-
-Pour une recherche insensible à la casse ou/et au format UTF-8, utilisez les fonctions `ngramDistanceCaseInsensitive, ngramDistanceUTF8, ngramDistanceCaseInsensitiveUTF8`.
-
-## ngramSearch(botte de foin, aiguille) {#ngramsearchhaystack-needle}
-
-Même que `ngramDistance` mais calcule la différence non symétrique entre `needle` et `haystack` – the number of n-grams from needle minus the common number of n-grams normalized by the number of `needle` n-grammes. Le plus proche d'un, le plus probable `needle` est dans le `haystack`. Peut être utile pour la recherche de chaîne floue.
-
-Pour une recherche insensible à la casse ou/et au format UTF-8, utilisez les fonctions `ngramSearchCaseInsensitive, ngramSearchUTF8, ngramSearchCaseInsensitiveUTF8`.
-
-!!! note "Note"
-    For UTF-8 case we use 3-gram distance. All these are not perfectly fair n-gram distances. We use 2-byte hashes to hash n-grams and then calculate the (non-)symmetric difference between these hash tables – collisions may occur. With UTF-8 case-insensitive format we do not use fair `tolower` function – we zero the 5-th bit (starting from zero) of each codepoint byte and first bit of zeroth byte if bytes more than one – this works for Latin and mostly for all Cyrillic letters.

-# Fonctions De Conversion De Type {#type-conversion-functions}
-
-## Problèmes courants des Conversions numériques {#numeric-conversion-issues}
-
-Lorsque vous convertissez une valeur d'un type de données à un autre, vous devez vous rappeler que dans le cas courant, il s'agit d'une opération dangereuse qui peut entraîner une perte de données. Une perte de données peut se produire si vous essayez d'ajuster la valeur d'un type de données plus grand à un type de données plus petit, ou si vous convertissez des valeurs entre différents types de données.
-
-ClickHouse a le [même comportement que les programmes C++ ](https://en.cppreference.com/w/cpp/language/implicit_conversion).
-
-## toInt (8/16/32/64) {#toint8163264}
-
-Convertit une valeur d'entrée en [Int](../../sql-reference/data-types/int-uint.md) type de données. Cette fonction comprend:
-
--   `toInt8(expr)` — Results in the `Int8` type de données.
--   `toInt16(expr)` — Results in the `Int16` type de données.
--   `toInt32(expr)` — Results in the `Int32` type de données.
--   `toInt64(expr)` — Results in the `Int64` type de données.
-
-**Paramètre**
-
--   `expr` — [Expression](../syntax.md#syntax-expressions) renvoyer un nombre ou une chaîne avec la représentation décimale d'un nombre. Les représentations binaires, octales et hexadécimales des nombres ne sont pas prises en charge. Les zéros principaux sont dépouillés.
-
-**Valeur renvoyée**
-
-Valeur entière dans le `Int8`, `Int16`, `Int32`, ou `Int64` type de données.
-
-Fonctions d'utilisation [l'arrondi vers zéro](https://en.wikipedia.org/wiki/Rounding#Rounding_towards_zero), ce qui signifie qu'ils tronquent des chiffres fractionnaires de nombres.
-
-Le comportement des fonctions pour le [NaN et Inf](../../sql-reference/data-types/float.md#data_type-float-nan-inf) arguments est indéfini. Rappelez-vous sur [problèmes de conversion numérique](#numeric-conversion-issues), lorsque vous utilisez les fonctions.

--   `toUInt8(expr)` — Results in the `UInt8` type de données.
--   `toUInt16(expr)` — Results in the `UInt16` type de données.
--   `toUInt32(expr)` — Results in the `UInt32` type de données.
--   `toUInt64(expr)` — Results in the `UInt64` type de données.
-
-**Paramètre**
-
--   `expr` — [Expression](../syntax.md#syntax-expressions) renvoyer un nombre ou une chaîne avec la représentation décimale d'un nombre. Les représentations binaires, octales et hexadécimales des nombres ne sont pas prises en charge. Les zéros principaux sont dépouillés.
-
-**Valeur renvoyée**
-
-Valeur entière dans le `UInt8`, `UInt16`, `UInt32`, ou `UInt64` type de données.
-
-Fonctions d'utilisation [l'arrondi vers zéro](https://en.wikipedia.org/wiki/Rounding#Rounding_towards_zero), ce qui signifie qu'ils tronquent des chiffres fractionnaires de nombres.
-
-Le comportement des fonctions pour les agruments négatifs et pour le [NaN et Inf](../../sql-reference/data-types/float.md#data_type-float-nan-inf) arguments est indéfini. Si vous passez une chaîne avec un nombre négatif, par exemple `'-32'`, ClickHouse soulève une exception. Rappelez-vous sur [problèmes de conversion numérique](#numeric-conversion-issues), lorsque vous utilisez les fonctions.

-
-## toString {#tostring}
-
-Fonctions de conversion entre des nombres, des chaînes (mais pas des chaînes fixes), des dates et des dates avec des heures.
-Toutes ces fonctions acceptent un argument.
-
-Lors de la conversion vers ou à partir d'une chaîne, la valeur est formatée ou analysée en utilisant les mêmes règles que pour le format TabSeparated (et presque tous les autres formats de texte). Si la chaîne ne peut pas être analysée, une exception est levée et la demande est annulée.
-
-Lors de la conversion de dates en nombres ou vice versa, la date correspond au nombre de jours depuis le début de L'époque Unix.
-Lors de la conversion de dates avec des heures en nombres ou vice versa, la date avec l'heure correspond au nombre de secondes depuis le début de L'époque Unix.
-
-Les formats date et date-avec-heure pour les fonctions toDate/toDateTime sont définis comme suit:
-
-``` text
-YYYY-MM-DD
-YYYY-MM-DD hh:mm:ss
-```
-
-À titre d'exception, si vous convertissez des types numériques UInt32, Int32, UInt64 ou Int64 à Date, et si le nombre est supérieur ou égal à 65536, le nombre est interprété comme un horodatage Unix (et non comme le nombre de jours) et est arrondi à la date. Cela permet de prendre en charge l'occurrence commune de l'écriture ‘toDate(unix_timestamp)’, qui autrement serait une erreur et nécessiterait d'écrire le plus lourd ‘toDate(toDateTime(unix_timestamp))’.
-
-La Conversion entre une date et une date avec l'heure est effectuée de manière naturelle: en ajoutant une heure nulle ou en supprimant l'heure.
-
-La Conversion entre types numériques utilise les mêmes règles que les affectations entre différents types numériques en C++.
-
-De plus, la fonction ToString de L'argument DateTime peut prendre un deuxième argument de chaîne contenant le nom du fuseau horaire. Exemple: `Asia/Yekaterinburg` Dans ce cas, l'heure est formatée en fonction du fuseau horaire spécifié.
-
-``` sql
-SELECT
-    now() AS now_local,
-    toString(now(), 'Asia/Yekaterinburg') AS now_yekat
-```
-
-``` text
-┌───────────now_local─┬─now_yekat───────────┐
-│ 2016-06-15 00:11:21 │ 2016-06-15 02:11:21 │
-└─────────────────────┴─────────────────────┘
-```
-
-Voir aussi l' `toUnixTimestamp` fonction.
-
-## toFixedString (s, N) {#tofixedstrings-n}
-
-Convertit un argument de type String en un type FixedString (N) (une chaîne de longueur fixe N). N doit être une constante.
-Si la chaîne a moins d'octets que N, elle est complétée avec des octets null à droite. Si la chaîne a plus d'octets que N, une exception est levée.
-
-## toStringCutToZero(s) {#tostringcuttozeros}
-
-Accepte un argument String ou FixedString. Renvoie la chaîne avec le contenu tronqué au premier octet zéro trouvé.
-
-Exemple:
-
-``` sql
-SELECT toFixedString('foo', 8) AS s, toStringCutToZero(s) AS s_cut
-```
-
-``` text
-┌─s─────────────┬─s_cut─┐
-│ foo\0\0\0\0\0 │ foo   │
-└───────────────┴───────┘
-```
-
-``` sql
-SELECT toFixedString('foo\0bar', 8) AS s, toStringCutToZero(s) AS s_cut
-```
-
-``` text
-┌─s──────────┬─s_cut─┐
-│ foo\0bar\0 │ foo   │
-└────────────┴───────┘

-## reinterpretAsInt (8/16/32/64) {#reinterpretasint8163264}
-
-## reinterpretAsFloat (32/64) {#reinterpretasfloat3264}
-
-## réinterprétasdate {#reinterpretasdate}
-
-## reinterpretAsDateTime {#reinterpretasdatetime}
-
-Ces fonctions acceptent une chaîne et interprètent les octets placés au début de la chaîne comme un nombre dans l'ordre de l'hôte (little endian). Si la chaîne n'est pas assez longue, les fonctions fonctionnent comme si la chaîne était remplie avec le nombre nécessaire d'octets nuls. Si la chaîne est plus longue que nécessaire, les octets supplémentaires sont ignorés. Une date est interprétée comme le nombre de jours depuis le début de l'Époque Unix, et une date avec le temps, est interprété comme le nombre de secondes écoulées depuis le début de l'Époque Unix.
-
-## reinterpretAsString {#type_conversion_functions-reinterpretAsString}
-
-Cette fonction accepte un nombre ou une date ou une date avec l'heure, et renvoie une chaîne contenant des octets représentant la valeur correspondante dans l'ordre de l'hôte (little endian). Les octets nuls sont supprimés de la fin. Par exemple, une valeur de type uint32 de 255 est une chaîne longue d'un octet.
-
-## reinterpretAsFixedString {#reinterpretasfixedstring}
-
-Cette fonction accepte un nombre ou une date ou une date avec l'heure, et renvoie une chaîne fixe contenant des octets représentant la valeur correspondante dans l'ordre de l'hôte (little endian). Les octets nuls sont supprimés de la fin. Par exemple, une valeur de type uint32 de 255 est une chaîne fixe longue d'un octet.
-
-## CAST (x, T) {#type_conversion_function-cast}
-
-Convertir ‘x’ à l' ‘t’ type de données. La syntaxe CAST (X comme t) est également prise en charge.
-
-Exemple:
-
-``` sql
-SELECT
-    '2016-06-15 23:00:00' AS timestamp,
-    CAST(timestamp AS DateTime) AS datetime,
-    CAST(timestamp AS Date) AS date,
-    CAST(timestamp, 'String') AS string,
-    CAST(timestamp, 'FixedString(22)') AS fixed_string
-```

-
-La Conversion en FixedString (N) ne fonctionne que pour les arguments de type String ou FixedString (N).

-Renvoie la “first significant subdomain”. C'est un concept non standard spécifique à Yandex.Metrica. Le premier sous-domaine significatif est un domaine de deuxième niveau s'il est ‘com’, ‘net’, ‘org’, ou ‘co’. Sinon, il est un domaine de troisième niveau. Exemple, `firstSignificantSubdomain (‘https://news.yandex.ru/’) = ‘yandex’, firstSignificantSubdomain (‘https://news.yandex.com.tr/’) = ‘yandex’`. La liste des “insignificant” les domaines de deuxième niveau et d'autres détails de mise en œuvre peuvent changer à l'avenir.
-
-### cutToFirstSignificantSubdomain {#cuttofirstsignificantsubdomain}
-
-Renvoie la partie du domaine qui inclut les sous-domaines de premier niveau “first significant subdomain” (voir l'explication ci-dessus).
-
-Exemple, `cutToFirstSignificantSubdomain('https://news.yandex.com.tr/') = 'yandex.com.tr'`.

-
-La même chose que ci-dessus, mais y compris la chaîne de requête et le fragment. Exemple: / top / nouvelles.le html?page = 2 # commentaires
-
-### queryString {#querystring}
-
-Retourne la chaîne de requête. Exemple: page = 1 & lr=213. query-string n'inclut pas le point d'interrogation initial, ainsi que # et tout ce qui suit #.
-
-### fragment {#fragment}
-
-Renvoie l'identificateur de fragment. fragment n'inclut pas le symbole de hachage initial.
-
-### queryStringAndFragment {#querystringandfragment}
-
-Renvoie la chaîne de requête et l'Identificateur de fragment. Exemple: page = 1 # 29390.
-
-### extractURLParameter (URL, nom) {#extracturlparameterurl-name}
-
-Renvoie la valeur de la ‘name’ paramètre dans l'URL, le cas échéant. Sinon, une chaîne vide. S'il y a beaucoup de paramètres avec ce nom, il renvoie la première occurrence. Cette fonction fonctionne en supposant que le nom du paramètre est codé dans L'URL exactement de la même manière que dans l'argument passé.
-
-### extractURLParameters (URL) {#extracturlparametersurl}
-
-Renvoie un tableau de chaînes name = value correspondant aux paramètres D'URL. Les valeurs ne sont en aucun cas décodées.
-
-### extractURLParameterNames (URL) {#extracturlparameternamesurl}
-
-Retourne un tableau de chaînes de noms correspondant aux noms des paramètres d'URL. Les valeurs ne sont en aucun cas décodées.
-
-### URLHierarchy (URL) {#urlhierarchyurl}
-
-Retourne un tableau contenant L'URL, tronquée à la fin par les symboles /,? dans le chemin et la chaîne de requête. Les caractères séparateurs consécutifs sont comptés comme un. La coupe est faite dans la position après tous les caractères de séparation consécutifs.
-
-### URLPathHierarchy (URL) {#urlpathhierarchyurl}
-
-La même chose que ci-dessus, mais sans le protocole et l'hôte dans le résultat. Le / les élément (racine) n'est pas inclus. Exemple: la fonction est utilisée pour implémenter l'arborescence des rapports de L'URL dans Yandex. Métrique.
-
-``` text
-URLPathHierarchy('https://example.com/browse/CONV-6788') =
-[
-    '/browse/',
-    '/browse/CONV-6788'
-]
-```
-
-### decodeURLComponent (URL) {#decodeurlcomponenturl}
-
-Renvoie L'URL décodée.
-Exemple:
-
-``` sql
-SELECT decodeURLComponent('http://127.0.0.1:8123/?query=SELECT%201%3B') AS DecodedURL;
-```
-
-``` text
-┌─DecodedURL─────────────────────────────┐
-│ http://127.0.0.1:8123/?query=SELECT 1; │
-└────────────────────────────────────────┘
-```
-
-## Fonctions qui suppriment une partie D'une URL {#functions-that-remove-part-of-a-url}

-toc_title: Travailler avec Yandex.Dictionnaires Metrica
----
-
-# Fonctions pour travailler avec Yandex.Dictionnaires Metrica {#functions-for-working-with-yandex-metrica-dictionaries}
-
-Pour que les fonctions ci-dessous fonctionnent, la configuration du serveur doit spécifier les chemins et les adresses pour obtenir tous les Yandex.Dictionnaires Metrica. Les dictionnaires sont chargés au premier appel de l'une de ces fonctions. Si les listes de référence ne peuvent pas être chargées, une exception est levée.
-
-Pour plus d'informations sur la création de listes de références, consultez la section “Dictionaries”.
-
-## Plusieurs Geobases {#multiple-geobases}
-
-ClickHouse soutient le travail avec plusieurs géobases alternatives (hiérarchies régionales) simultanément, afin de soutenir diverses perspectives sur les pays auxquels appartiennent certaines régions.
-
-Le ‘clickhouse-server’ config spécifie le fichier avec l'échelon régional::`<path_to_regions_hierarchy_file>/opt/geo/regions_hierarchy.txt</path_to_regions_hierarchy_file>`
-
-Outre ce fichier, il recherche également les fichiers à proximité qui ont le symbole _ et tout suffixe ajouté au nom (avant l'extension de fichier).
-Par exemple, il trouvera également le fichier `/opt/geo/regions_hierarchy_ua.txt` si présente.
-
-`ua` est appelée la clé du dictionnaire. Pour un dictionnaire sans suffixe, la clé est une chaîne vide.
-
-Tous les dictionnaires sont rechargés dans l'exécution (une fois toutes les secondes, comme défini dans le paramètre de configuration builtin_dictionaries_reload_interval, ou une fois par heure par défaut). Cependant, la liste des dictionnaires disponibles est définie une fois, lorsque le serveur démarre.
-
-All functions for working with regions have an optional argument at the end – the dictionary key. It is referred to as the geobase.
-Exemple:
-
-``` sql
-regionToCountry(RegionID) – Uses the default dictionary: /opt/geo/regions_hierarchy.txt
-regionToCountry(RegionID, '') – Uses the default dictionary: /opt/geo/regions_hierarchy.txt
-regionToCountry(RegionID, 'ua') – Uses the dictionary for the 'ua' key: /opt/geo/regions_hierarchy_ua.txt
-```
-
-### regionToCity (id \[, geobase\]) {#regiontocityid-geobase}
-
-Accepts a UInt32 number – the region ID from the Yandex geobase. If this region is a city or part of a city, it returns the region ID for the appropriate city. Otherwise, returns 0.
-
-### regionToArea (id \[, geobase\]) {#regiontoareaid-geobase}
-
-Convertit une région en une zone (tapez 5 dans la géobase). Dans tous les autres cas, cette fonction est la même que ‘regionToCity’.
-
-``` sql
-SELECT DISTINCT regionToName(regionToArea(toUInt32(number), 'ua'))
-FROM system.numbers
-LIMIT 15
-```
-
-``` text

-
-### regionToDistrict(id \[, geobase\]) {#regiontodistrictid-geobase}
-
-Convertit une région en district fédéral (type 4 dans la géobase). Dans tous les autres cas, cette fonction est la même que ‘regionToCity’.
-
-``` sql
-SELECT DISTINCT regionToName(regionToDistrict(toUInt32(number), 'ua'))
-FROM system.numbers
-LIMIT 15

-
-### regionToCountry (id \[, geobase\]) {#regiontocountryid-geobase}
-
-Convertit une région en un pays. Dans tous les autres cas, cette fonction est la même que ‘regionToCity’.
-Exemple: `regionToCountry(toUInt32(213)) = 225` convertit Moscou (213) en Russie (225).
-
-### regionToContinent(id \[, géobase\]) {#regiontocontinentid-geobase}
-
-Convertit une région en continent. Dans tous les autres cas, cette fonction est la même que ‘regionToCity’.
-Exemple: `regionToContinent(toUInt32(213)) = 10001` convertit Moscou (213) en Eurasie (10001).
-
-### regionToTopContinent (#regiontotopcontinent) {#regiontotopcontinent-regiontotopcontinent}

-
-### regionToPopulation (id \[, geobase\]) {#regiontopopulationid-geobase}
-
-Obtient la population d'une région.
-La population peut être enregistrée dans des fichiers avec la géobase. Voir la section “External dictionaries”.
-Si la population n'est pas enregistrée pour la région, elle renvoie 0.

-### Dans les opérateurs {#select-in-operators}
-
-Le `IN`, `NOT IN`, `GLOBAL IN`, et `GLOBAL NOT IN` les opérateurs sont traitées séparément, car leur fonctionnalité est assez riche.
-
-Le côté gauche de l'opérateur, soit une seule colonne ou un tuple.
-
-Exemple:
-
-``` sql
-SELECT UserID IN (123, 456) FROM ...
-SELECT (CounterID, UserID) IN ((34, 123), (101500, 456)) FROM ...
-```
-
-Si le côté gauche est une colonne unique qui est dans l'index, et le côté droit est un ensemble de constantes, le système utilise l'index pour le traitement de la requête.
-
-Don't list too many values explicitly (i.e. millions). If a data set is large, put it in a temporary table (for example, see the section “External data for query processing”), puis utiliser une sous-requête.
-
-Le côté droit de l'opérateur peut être un ensemble d'expressions constantes, un ensemble de tuples avec des expressions constantes (illustrées dans les exemples ci-dessus), ou le nom d'une table de base de données ou une sous-requête SELECT entre parenthèses.
-
-Si le côté droit de l'opérateur est le nom d'une table (par exemple, `UserID IN users`), ceci est équivalent à la sous-requête `UserID IN (SELECT * FROM users)`. Utilisez ceci lorsque vous travaillez avec des données externes envoyées avec la requête. Par exemple, la requête peut être envoyée avec un ensemble d'ID utilisateur chargés dans le ‘users’ table temporaire, qui doit être filtrée.
-
-Si le côté droit de l'opérateur est un nom de table qui a le moteur Set (un ensemble de données préparé qui est toujours en RAM), l'ensemble de données ne sera pas créé à nouveau pour chaque requête.
-
-La sous-requête peut spécifier plusieurs colonnes pour filtrer les tuples.
-Exemple:
-
-``` sql
-SELECT (CounterID, UserID) IN (SELECT CounterID, UserID FROM ...) FROM ...
-```
-
-Les colonnes à gauche et à droite de l'opérateur doit avoir le même type.
-
-L'opérateur IN et la sous-requête peuvent se produire dans n'importe quelle partie de la requête, y compris dans les fonctions d'agrégation et les fonctions lambda.
-Exemple:
-
-``` sql
-SELECT
-    EventDate,
-    avg(UserID IN
-    (
-        SELECT UserID
-        FROM test.hits
-        WHERE EventDate = toDate('2014-03-17')
-    )) AS ratio
-FROM test.hits
-GROUP BY EventDate
-ORDER BY EventDate ASC
-```
-
-``` text
-┌──EventDate─┬────ratio─┐
-│ 2014-03-17 │        1 │
-│ 2014-03-18 │ 0.807696 │

-│ 2014-03-22 │ 0.647851 │
-│ 2014-03-23 │ 0.648416 │
-└────────────┴──────────┘
-```
-
-Pour chaque jour après le 17 mars, comptez le pourcentage de pages vues par les utilisateurs qui ont visité le site le 17 mars.
-Une sous-requête dans la clause est toujours exécuter une seule fois sur un seul serveur. Il n'y a pas de sous-requêtes dépendantes.
-
-## Le Traitement NULL {#null-processing-1}
-
-Pendant le traitement de la demande, l'opérateur n'assume que le résultat d'une opération avec [NULL](../syntax.md#null-literal) est toujours égale à `0` indépendamment de savoir si `NULL` est sur le côté droit ou gauche de l'opérateur. `NULL` les valeurs ne sont incluses dans aucun jeu de données, ne correspondent pas entre elles et ne peuvent pas être comparées.
-
-Voici un exemple avec le `t_null` table:
-
-``` text

-L'exécution de la requête `SELECT x FROM t_null WHERE y IN (NULL,3)` vous donne le résultat suivant:
-
-``` text
-┌─x─┐
-│ 2 │
-└───┘
-```
-
-Vous pouvez voir que la ligne dans laquelle `y = NULL` est jeté hors de résultats de la requête. C'est parce que ClickHouse ne peut pas décider si `NULL` est inclus dans le `(NULL,3)` ensemble, les retours `0` comme le résultat de l'opération, et `SELECT` exclut cette ligne de la sortie finale.
-
-``` sql
-SELECT y IN (NULL, 3)
-FROM t_null

-## Sous-Requêtes Distribuées {#select-distributed-subqueries}
-
-Il y a deux options pour IN-S avec des sous-requêtes (similaires aux jointures): normal `IN` / `JOIN` et `GLOBAL IN` / `GLOBAL JOIN`. Ils diffèrent dans la façon dont ils sont exécutés pour le traitement des requêtes distribuées.
-
-!!! attention "Attention"
-    Rappelez-vous que les algorithmes décrits ci-dessous peuvent travailler différemment en fonction de la [paramètre](../../operations/settings/settings.md) `distributed_product_mode` paramètre.
-
-Lors de l'utilisation de l'IN régulier, la requête est envoyée à des serveurs distants, et chacun d'eux exécute les sous-requêtes dans le `IN` ou `JOIN` clause.
-
-Lors de l'utilisation de `GLOBAL IN` / `GLOBAL JOINs`, d'abord toutes les sous-requêtes sont exécutées pour `GLOBAL IN` / `GLOBAL JOINs`, et les résultats sont recueillis dans des tableaux temporaires. Ensuite, les tables temporaires sont envoyés à chaque serveur distant, où les requêtes sont exécutées à l'aide temporaire de données.
-
-Pour une requête non distribuée, utilisez `IN` / `JOIN`.
-
-Soyez prudent lorsque vous utilisez des sous-requêtes dans le `IN` / `JOIN` clauses pour le traitement des requêtes distribuées.
-
-Regardons quelques exemples. Supposons que chaque serveur du cluster a un **local_table**. Chaque serveur dispose également d'une **table distributed_table** table avec le **Distribué** type, qui regarde tous les serveurs du cluster.
-
-Pour une requête à l' **table distributed_table**, la requête sera envoyée à tous les serveurs distants et exécutée sur eux en utilisant le **local_table**.
-
-Par exemple, la requête
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table
-```
-
-sera envoyé à tous les serveurs distants
-
-``` sql
-SELECT uniq(UserID) FROM local_table
-```
-
-et l'exécuter sur chacun d'eux en parallèle, jusqu'à ce qu'il atteigne le stade où les résultats intermédiaires peuvent être combinés. Ensuite, les résultats intermédiaires seront retournés au demandeur de serveur et de fusion, et le résultat final sera envoyé au client.
-
-Examinons maintenant une requête avec IN:
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM local_table WHERE CounterID = 34)
-```
-
--   Calcul de l'intersection des audiences de deux sites.
-
-Cette requête sera envoyée à tous les serveurs distants
-
-``` sql
-SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM local_table WHERE CounterID = 34)
-```
-
-En d'autres termes, l'ensemble de données de la clause IN sera collecté sur chaque serveur indépendamment, uniquement à travers les données stockées localement sur chacun des serveurs.
-
-Cela fonctionnera correctement et de manière optimale si vous êtes prêt pour ce cas et que vous avez réparti les données entre les serveurs de cluster de telle sorte que les données d'un seul ID utilisateur résident entièrement sur un seul serveur. Dans ce cas, toutes les données nécessaires seront disponibles localement sur chaque serveur. Sinon, le résultat sera erroné. Nous nous référons à cette variation de la requête que “local IN”.
-
-Pour corriger le fonctionnement de la requête lorsque les données sont réparties aléatoirement sur les serveurs de cluster, vous pouvez spécifier **table distributed_table** à l'intérieur d'une sous-requête. La requête ressemblerait à ceci:
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)
-```
-
-Cette requête sera envoyée à tous les serveurs distants
-
-``` sql
-SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)
-```
-
-La sous-requête commencera à s'exécuter sur chaque serveur distant. Étant donné que la sous-requête utilise une table distribuée, la sous-requête qui se trouve sur chaque serveur distant sera renvoyée à chaque serveur distant comme
-
-``` sql
-SELECT UserID FROM local_table WHERE CounterID = 34
-```
-
-Par exemple, si vous avez un cluster de 100 SERVEURS, l'exécution de la requête entière nécessitera 10 000 requêtes élémentaires, ce qui est généralement considéré comme inacceptable.
-
-Dans de tels cas, vous devez toujours utiliser GLOBAL IN au lieu de IN. Voyons comment cela fonctionne pour la requête
-
-``` sql
-SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID GLOBAL IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)
-```
-
-Le serveur demandeur exécutera la sous requête
-
-``` sql
-SELECT UserID FROM distributed_table WHERE CounterID = 34
-```
-
-et le résultat sera mis dans une table temporaire en RAM. Ensuite, la demande sera envoyée à chaque serveur distant
-
-``` sql
-SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID GLOBAL IN _data1
-```
-
-et la table temporaire `_data1` sera envoyé à chaque serveur distant avec la requête (le nom de la table temporaire est défini par l'implémentation).
-
-Ceci est plus optimal que d'utiliser la normale dans. Cependant, gardez les points suivants à l'esprit:
-
-1.  Lors de la création d'une table temporaire, les données ne sont pas uniques. Pour réduire le volume de données transmises sur le réseau, spécifiez DISTINCT dans la sous-requête. (Vous n'avez pas besoin de le faire pour un IN normal.)
-2.  La table temporaire sera envoyé à tous les serveurs distants. La Transmission ne tient pas compte de la topologie du réseau. Par exemple, si 10 serveurs distants résident dans un centre de données très distant par rapport au serveur demandeur, les données seront envoyées 10 fois sur le canal au centre de données distant. Essayez d'éviter les grands ensembles de données lorsque vous utilisez GLOBAL IN.
-3.  Lors de la transmission de données à des serveurs distants, les restrictions sur la bande passante réseau ne sont pas configurables. Vous pourriez surcharger le réseau.
-4.  Essayez de distribuer les données entre les serveurs afin que vous n'ayez pas besoin D'utiliser GLOBAL IN sur une base régulière.
-5.  Si vous devez utiliser GLOBAL in souvent, planifiez l'emplacement du cluster ClickHouse de sorte qu'un seul groupe de répliques ne réside pas dans plus d'un centre de données avec un réseau rapide entre eux, de sorte qu'une requête puisse être traitée entièrement dans un seul centre de données.
-
-Il est également judicieux de spécifier une table locale dans le `GLOBAL IN` clause, dans le cas où cette table locale est uniquement disponible sur le serveur demandeur et que vous souhaitez utiliser les données de celui-ci sur des serveurs distants.

-## Opérateurs pour travailler avec des Dates et des heures {#operators-datetime}
-
-### EXTRACT {#operator-extract}
-
-``` sql
-EXTRACT(part FROM date);
-```
-
-Extraire des parties d'une date donnée. Par exemple, vous pouvez récupérer un mois à partir d'une date donnée, ou d'une seconde à partir d'un moment.
-
-Le `part` paramètre spécifie la partie de la date à récupérer. Les valeurs suivantes sont disponibles:
-
--   `DAY` — The day of the month. Possible values: 1–31.
--   `MONTH` — The number of a month. Possible values: 1–12.
--   `YEAR` — The year.
--   `SECOND` — The second. Possible values: 0–59.
--   `MINUTE` — The minute. Possible values: 0–59.
--   `HOUR` — The hour. Possible values: 0–23.
-
-Le `part` le paramètre est insensible à la casse.
-
-Le `date` paramètre spécifie la date ou l'heure à traiter. Soit [Date](../../sql-reference/data-types/date.md) ou [DateTime](../../sql-reference/data-types/datetime.md) le type est pris en charge.
-
-Exemple:
-
-``` sql
-SELECT EXTRACT(DAY FROM toDate('2017-06-15'));
-SELECT EXTRACT(MONTH FROM toDate('2017-06-15'));
-SELECT EXTRACT(YEAR FROM toDate('2017-06-15'));
-```
-
-Dans l'exemple suivant, nous créons un tableau et de les insérer dans une valeur avec le `DateTime` type.
-
-``` sql
-CREATE TABLE test.Orders
-(
-    OrderId UInt64,
-    OrderName String,
-    OrderDate DateTime
-)
-ENGINE = Log;
-```
-
-``` sql
-INSERT INTO test.Orders VALUES (1, 'Jarlsberg Cheese', toDateTime('2008-10-11 13:23:44'));
-```
-
-``` sql
-SELECT
-    toYear(OrderDate) AS OrderYear,
-    toMonth(OrderDate) AS OrderMonth,
-    toDayOfMonth(OrderDate) AS OrderDay,
-    toHour(OrderDate) AS OrderHour,
-    toMinute(OrderDate) AS OrderMinute,
-    toSecond(OrderDate) AS OrderSecond
-FROM test.Orders;
-```
-
-``` text
-┌─OrderYear─┬─OrderMonth─┬─OrderDay─┬─OrderHour─┬─OrderMinute─┬─OrderSecond─┐
-│      2008 │         10 │       11 │        13 │          23 │          44 │
-└───────────┴────────────┴──────────┴───────────┴─────────────┴─────────────┘

-
-Vous pouvez voir plus d'exemples de [test](https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/00619_extract.sql).
-
-### INTERVAL {#operator-interval}
-
-Crée un [Intervalle](../../sql-reference/data-types/special-data-types/interval.md)- valeur de type qui doit être utilisée dans les opérations arithmétiques avec [Date](../../sql-reference/data-types/date.md) et [DateTime](../../sql-reference/data-types/datetime.md)-type de valeurs.
-
-Types d'intervalles:
-- `SECOND`
-- `MINUTE`
-- `HOUR`
-- `DAY`
-- `WEEK`
-- `MONTH`
-- `QUARTER`
-- `YEAR`
-
-!!! warning "Avertissement"
-    Les intervalles avec différents types ne peuvent pas être combinés. Vous ne pouvez pas utiliser des expressions comme `INTERVAL 4 DAY 1 HOUR`. Spécifiez des intervalles en unités inférieures ou égales à la plus petite unité de l'intervalle, par exemple, `INTERVAL 25 HOUR`. Vous pouvez utiliser les opérations consécutives, comme dans l'exemple ci-dessous.
-
-Exemple:
-
-``` sql
-SELECT now() AS current_date_time, current_date_time + INTERVAL 4 DAY + INTERVAL 3 HOUR
-```
-
-``` text
-┌───current_date_time─┬─plus(plus(now(), toIntervalDay(4)), toIntervalHour(3))─┐
-│ 2019-10-23 11:16:28 │                                    2019-10-27 14:16:28 │

-
-## Opérateur De Négation Logique {#logical-negation-operator}
-
-`NOT a` – The `not(a)` fonction.
-
-## Logique ET de l'Opérateur {#logical-and-operator}
-
-`a AND b` – The`and(a, b)` fonction.
-
-## Logique ou opérateur {#logical-or-operator}
-
-`a OR b` – The `or(a, b)` fonction.
-
-## Opérateur Conditionnel {#conditional-operator}
-
-`a ? b : c` – The `if(a, b, c)` fonction.
-
-Note:
-
-L'opérateur conditionnel calcule les valeurs de b et c, puis vérifie si la condition a est remplie, puis renvoie la valeur correspondante. Si `b` ou `C` est un [arrayJoin()](../../sql-reference/functions/array-join.md#functions_arrayjoin) fonction, chaque ligne sera répliquée indépendamment de la “a” condition.
-
-## Expression Conditionnelle {#operator_case}
-
-``` sql
-CASE [x]
-    WHEN a THEN b
-    [WHEN ... THEN ...]
-    [ELSE c]
-END
-```
-
-Si `x` est spécifié, alors `transform(x, [a, ...], [b, ...], c)` function is used. Otherwise – `multiIf(a, b, ..., c)`.
-
-Si il n'y a pas de `ELSE c` dans l'expression, la valeur par défaut est `NULL`.
-
-Le `transform` la fonction ne fonctionne pas avec `NULL`.
-
-## Opérateur De Concaténation {#concatenation-operator}
-
-`s1 || s2` – The `concat(s1, s2) function.`
-
-## Opérateur De Création Lambda {#lambda-creation-operator}
-
-`x -> expr` – The `lambda(x, expr) function.`
-
-Les opérateurs suivants n'ont pas de priorité puisqu'ils sont des parenthèses:
-
-## Opérateur De Création De Tableau {#array-creation-operator}
-
-`[x1, ...]` – The `array(x1, ...) function.`
-
-## Opérateur De Création De Tuple {#tuple-creation-operator}
-
-`(x1, x2, ...)` – The `tuple(x2, x2, ...) function.`
-
-## Associativité {#associativity}
-
-Tous les opérateurs binaires ont associativité gauche. Exemple, `1 + 2 + 3` est transformé à `plus(plus(1, 2), 3)`.
-Parfois, cela ne fonctionne pas de la façon que vous attendez. Exemple, `SELECT 4 > 2 > 3` résultat sera 0.
-
-Pour l'efficacité, le `and` et `or` les fonctions acceptent n'importe quel nombre d'arguments. Les chaînes de `AND` et `OR` les opérateurs se sont transformés en un seul appel de ces fonctions.
-
-## La vérification de `NULL` {#checking-for-null}
-
-Clickhouse soutient le `IS NULL` et `IS NOT NULL` opérateur.
-
-### IS NULL {#operator-is-null}
-
--   Pour [Nullable](../../sql-reference/data-types/nullable.md) type de valeurs, l' `IS NULL` opérateur retourne:
-    -   `1` si la valeur est `NULL`.
-    -   `0` autrement.
--   Pour les autres valeurs, la `IS NULL` l'opérateur renvoie toujours `0`.
-
-<!-- -->
-
-``` sql
-SELECT x+100 FROM t_null WHERE y IS NULL
-```
-
-``` text
-┌─plus(x, 100)─┐

-
-### IS NOT NULL {#is-not-null}
-
--   Pour [Nullable](../../sql-reference/data-types/nullable.md) type de valeurs, l' `IS NOT NULL` opérateur retourne:
-    -   `0` si la valeur est `NULL`.
-    -   `1` autrement.
--   Pour les autres valeurs, la `IS NOT NULL` l'opérateur renvoie toujours `1`.

----
-
-## ALTER {#query_language_queries_alter}
-
-Le `ALTER` la requête est prise en charge uniquement pour `*MergeTree` des tables, ainsi que `Merge`et`Distributed`. La requête a plusieurs variantes.
-
-### Manipulations De Colonne {#column-manipulations}
-
-Modification de la structure de la table.
-
-``` sql
-ALTER TABLE [db].name [ON CLUSTER cluster] ADD|DROP|CLEAR|COMMENT|MODIFY COLUMN ...
-```
-
-Dans la requête, spécifiez une liste d'une ou plusieurs actions séparées par des virgules.
-Chaque action est une opération sur une colonne.
-
-Les actions suivantes sont prises en charge:
-
--   [ADD COLUMN](#alter_add-column) — Adds a new column to the table.
--   [DROP COLUMN](#alter_drop-column) — Deletes the column.
--   [CLEAR COLUMN](#alter_clear-column) — Resets column values.
--   [COMMENT COLUMN](#alter_comment-column) — Adds a text comment to the column.
--   [MODIFY COLUMN](#alter_modify-column) — Changes column's type, default expression and TTL.
-
-Ces actions sont décrites en détail ci-dessous.
-
-#### ADD COLUMN {#alter_add-column}
-
-``` sql
-ADD COLUMN [IF NOT EXISTS] name [type] [default_expr] [codec] [AFTER name_after]
-```
-
-Ajoute une nouvelle colonne à la table spécifiée `name`, `type`, [`codec`](create.md#codecs) et `default_expr` (voir la section [Expressions par défaut](create.md#create-default-values)).
-
-Si l' `IF NOT EXISTS` la clause est incluse, la requête ne retournera pas d'erreur si la colonne existe déjà. Si vous spécifiez `AFTER name_after` (le nom d'une autre colonne), la colonne est ajoutée après celle spécifiée dans la liste des colonnes de la table. Sinon, la colonne est ajoutée à la fin de la table. Notez qu'il n'existe aucun moyen d'ajouter une colonne au début d'un tableau. Pour une chaîne d'actions, `name_after` peut être le nom d'une colonne est ajoutée dans l'une des actions précédentes.
-
-L'ajout d'une colonne modifie simplement la structure de la table, sans effectuer d'actions avec des données. Les données n'apparaissent pas sur le disque après la `ALTER`. Si les données sont manquantes pour une colonne lors de la lecture de la table, elles sont remplies avec des valeurs par défaut (en exécutant l'expression par défaut s'il y en a une, ou en utilisant des zéros ou des chaînes vides). La colonne apparaît sur le disque après la fusion des parties de données (voir [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md)).
-
-Cette approche nous permet de compléter le `ALTER` requête instantanément, sans augmenter le volume de données anciennes.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits ADD COLUMN browser String AFTER user_id
-```
-
-#### DROP COLUMN {#alter_drop-column}
-
-``` sql
-DROP COLUMN [IF EXISTS] name
-```
-
-Supprime la colonne avec le nom `name`. Si l' `IF EXISTS` la clause est spécifiée, la requête ne retournera pas d'erreur si la colonne n'existe pas.
-
-Supprime les données du système de fichiers. Comme cela supprime des fichiers entiers, la requête est terminée presque instantanément.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits DROP COLUMN browser
-```
-
-#### CLEAR COLUMN {#alter_clear-column}
-
-``` sql
-CLEAR COLUMN [IF EXISTS] name IN PARTITION partition_name
-```
-
-Réinitialise toutes les données dans une colonne pour une partition spécifiée. En savoir plus sur la définition du nom de la partition dans la section [Comment spécifier l'expression de partition](#alter-how-to-specify-part-expr).
-
-Si l' `IF EXISTS` la clause est spécifiée, la requête ne retournera pas d'erreur si la colonne n'existe pas.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits CLEAR COLUMN browser IN PARTITION tuple()
-```
-
-#### COMMENT COLUMN {#alter_comment-column}
-
-``` sql
-COMMENT COLUMN [IF EXISTS] name 'comment'
-```
-
-Ajoute un commentaire à la colonne. Si l' `IF EXISTS` la clause est spécifiée, la requête ne retournera pas d'erreur si la colonne n'existe pas.
-
-Chaque colonne peut avoir un commentaire. Si un commentaire existe déjà pour la colonne, un nouveau commentaire remplace le précédent commentaire.
-
-Les commentaires sont stockés dans le `comment_expression` colonne renvoyée par le [DESCRIBE TABLE](misc.md#misc-describe-table) requête.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits COMMENT COLUMN browser 'The table shows the browser used for accessing the site.'
-```
-
-#### MODIFY COLUMN {#alter_modify-column}
-
-``` sql
-MODIFY COLUMN [IF EXISTS] name [type] [default_expr] [TTL]
-```
-
-Cette requête modifie le `name` les propriétés de la colonne:
-
--   Type
-
--   Expression par défaut
-
--   TTL
-
-        For examples of columns TTL modifying, see [Column TTL](../engines/table_engines/mergetree_family/mergetree.md#mergetree-column-ttl).
-
-Si l' `IF EXISTS` la clause est spécifiée, la requête ne retournera pas d'erreur si la colonne n'existe pas.
-
-Lors de la modification du type, les valeurs sont converties comme si [toType](../../sql-reference/functions/type-conversion-functions.md) les fonctions ont été appliquées. Si seule l'expression par défaut est modifiée, la requête ne fait rien de complexe et est terminée presque instantanément.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits MODIFY COLUMN browser Array(String)
-```
-
-Changing the column type is the only complex action – it changes the contents of files with data. For large tables, this may take a long time.
-
-Il y a plusieurs étapes de traitement:
-
--   Préparation de (nouveaux) fichiers temporaires avec des données modifiées.
--   Renommer les anciens fichiers.
--   Renommer les (nouveaux) fichiers temporaires en anciens noms.
--   Suppression des anciens fichiers.
-
-Seule la première étape prend du temps. Si il y a un échec à ce stade, les données ne sont pas modifiées.
-En cas d'échec au cours d'une des étapes successives, les données peuvent être restaurées manuellement. L'exception est si les anciens fichiers ont été supprimés du système de fichiers mais que les données des nouveaux fichiers n'ont pas été écrites sur le disque et ont été perdues.
-
-Le `ALTER` la requête de modification des colonnes est répliquée. Les instructions sont enregistrées dans ZooKeeper, puis chaque réplique les applique. Tout `ALTER` les requêtes sont exécutées dans le même ordre. La requête attend que les actions appropriées soient terminées sur les autres répliques. Cependant, une requête pour modifier des colonnes dans une table répliquée peut être interrompue, et toutes les actions seront effectuées de manière asynchrone.
-
-#### Modifier les limites de la requête {#alter-query-limitations}
-
-Le `ALTER` query vous permet de créer et de supprimer des éléments distincts (colonnes) dans des structures de données imbriquées, mais pas des structures de données imbriquées entières. Pour ajouter une structure de données imbriquée, vous pouvez ajouter des colonnes avec un nom comme `name.nested_name` et le type `Array(T)`. Une structure de données imbriquée est équivalente à plusieurs colonnes de tableau avec un nom qui a le même préfixe avant le point.
-
-Il n'y a pas de support pour supprimer des colonnes dans la clé primaire ou la clé d'échantillonnage (colonnes qui sont utilisées dans le `ENGINE` expression). La modification du type des colonnes incluses dans la clé primaire n'est possible que si cette modification n'entraîne pas la modification des données (par exemple, vous êtes autorisé à ajouter des valeurs à une énumération ou à modifier un type de `DateTime` de `UInt32`).
-
-Si l' `ALTER` la requête n'est pas suffisante pour apporter les modifications de table dont vous avez besoin, vous pouvez créer une nouvelle table, y copier les données en utilisant le [INSERT SELECT](insert-into.md#insert_query_insert-select) requête, puis changer les tables en utilisant le [RENAME](misc.md#misc_operations-rename) requête et supprimer l'ancienne table. Vous pouvez utiliser l' [clickhouse-copieur](../../operations/utilities/clickhouse-copier.md) comme une alternative à la `INSERT SELECT` requête.
-
-Le `ALTER` query bloque toutes les lectures et écritures pour la table. En d'autres termes, si une longue `SELECT` est en cours d'exécution au moment de la `ALTER` requête, la `ALTER` la requête va attendre qu'elle se termine. Dans le même temps, toutes les nouvelles requêtes à la même table attendre que ce `ALTER` est en cours d'exécution.
-
-Pour les tables qui ne stockent pas les données elles-mêmes (telles que `Merge` et `Distributed`), `ALTER` change simplement la structure de la table, et ne change pas la structure des tables subordonnées. Par exemple, lors de L'exécution de ALTER pour un `Distributed` table, vous devrez également exécuter `ALTER` pour les tables sur tous les serveurs distants.
-
-### Manipulations avec des Expressions clés {#manipulations-with-key-expressions}
-
-La commande suivante est prise en charge:
-
-``` sql
-MODIFY ORDER BY new_expression
-```
-
-Cela ne fonctionne que pour les tables du [`MergeTree`](../../engines/table-engines/mergetree-family/mergetree.md) de la famille (y compris les
-[répliqué](../../engines/table-engines/mergetree-family/replication.md) table). La commande change l'
-[clé de tri](../../engines/table-engines/mergetree-family/mergetree.md) de la table
-de `new_expression` (une expression ou un tuple d'expressions). Clé primaire reste le même.
-
-La commande est légère en ce sens qu'elle ne modifie que les métadonnées. Pour conserver la propriété cette partie de données
-les lignes sont ordonnées par l'expression de clé de tri vous ne pouvez pas ajouter d'expressions contenant des colonnes existantes
-à la clé de tri (seules les colonnes ajoutées par `ADD COLUMN` commande dans le même `ALTER` requête).
-
-### Manipulations avec des Indices de saut de données {#manipulations-with-data-skipping-indices}
-
-Cela ne fonctionne que pour les tables du [`*MergeTree`](../../engines/table-engines/mergetree-family/mergetree.md) de la famille (y compris les
-[répliqué](../../engines/table-engines/mergetree-family/replication.md) table). Les opérations suivantes
-sont disponibles:
-
--   `ALTER TABLE [db].name ADD INDEX name expression TYPE type GRANULARITY value AFTER name [AFTER name2]` - Ajoute la description de l'index aux métadonnées des tables.
-
--   `ALTER TABLE [db].name DROP INDEX name` - Supprime la description de l'index des métadonnées des tables et supprime les fichiers d'index du disque.
-
-Ces commandes sont légères dans le sens où elles ne modifient que les métadonnées ou suppriment des fichiers.
-En outre, ils sont répliqués (synchronisation des métadonnées des indices via ZooKeeper).
-
-### Manipulations avec contraintes {#manipulations-with-constraints}
-
-En voir plus sur [contraintes](create.md#constraints)
-
-Les contraintes peuvent être ajoutées ou supprimées à l'aide de la syntaxe suivante:
-
-``` sql
-ALTER TABLE [db].name ADD CONSTRAINT constraint_name CHECK expression;
-ALTER TABLE [db].name DROP CONSTRAINT constraint_name;
-```
-
-Les requêtes ajouteront ou supprimeront des métadonnées sur les contraintes de la table afin qu'elles soient traitées immédiatement.
-
-Contrainte de vérifier *ne sera pas exécuté* sur les données existantes si elle a été ajoutée.
-
-Toutes les modifications sur les tables répliquées sont diffusées sur ZooKeeper et seront donc appliquées sur d'autres répliques.
-
-### Manipulations avec des Partitions et des pièces {#alter_manipulations-with-partitions}
-
-Les opérations suivantes avec [partition](../../engines/table-engines/mergetree-family/custom-partitioning-key.md) sont disponibles:
-
--   [DETACH PARTITION](#alter_detach-partition) – Moves a partition to the `detached` répertoire et de l'oublier.
--   [DROP PARTITION](#alter_drop-partition) – Deletes a partition.
--   [ATTACH PART\|PARTITION](#alter_attach-partition) – Adds a part or partition from the `detached` répertoire à la table.
--   [ATTACH PARTITION FROM](#alter_attach-partition-from) – Copies the data partition from one table to another and adds.
--   [REPLACE PARTITION](#alter_replace-partition) - Copie la partition de données d'une table à l'autre et la remplace.
--   [MOVE PARTITION TO TABLE](#alter_move_to_table-partition)(#alter_move_to_table-partition) - déplace la partition de données d'une table à l'autre.
--   [CLEAR COLUMN IN PARTITION](#alter_clear-column-partition) - Rétablit la valeur d'une colonne spécifiée dans une partition.
--   [CLEAR INDEX IN PARTITION](#alter_clear-index-partition) - Réinitialise l'index secondaire spécifié dans une partition.
--   [FREEZE PARTITION](#alter_freeze-partition) – Creates a backup of a partition.
--   [FETCH PARTITION](#alter_fetch-partition) – Downloads a partition from another server.
--   [MOVE PARTITION\|PART](#alter_move-partition) – Move partition/data part to another disk or volume.
-
-<!-- -->
-
-#### DETACH PARTITION {#alter_detach-partition}
-
-``` sql
-ALTER TABLE table_name DETACH PARTITION partition_expr
-```
-
-Déplace toutes les données de la partition spécifiée vers `detached` répertoire. Le serveur oublie la partition de données détachée comme si elle n'existait pas. Le serveur ne connaîtra pas ces données tant que vous n'aurez pas [ATTACH](#alter_attach-partition) requête.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits DETACH PARTITION 201901
-```
-
-Lisez à propos de la définition de l'expression de partition dans une section [Comment spécifier l'expression de partition](#alter-how-to-specify-part-expr).
-
-Une fois la requête exécutée, vous pouvez faire ce que vous voulez avec les données du `detached` directory — delete it from the file system, or just leave it.
-
-This query is replicated – it moves the data to the `detached` répertoire sur toutes les répliques. Notez que vous ne pouvez exécuter cette requête que sur un réplica leader. Pour savoir si une réplique est un leader, effectuez le `SELECT` requête à l' [système.réplique](../../operations/system-tables.md#system_tables-replicas) table. Alternativement, il est plus facile de faire une `DETACH` requête sur toutes les répliques - toutes les répliques lancent une exception, à l'exception de la réplique leader.
-
-#### DROP PARTITION {#alter_drop-partition}
-
-``` sql
-ALTER TABLE table_name DROP PARTITION partition_expr
-```
-
-Supprime la partition spécifiée de la table. Cette requête marque la partition comme inactive et supprime complètement les données, environ en 10 minutes.
-
-Lisez à propos de la définition de l'expression de partition dans une section [Comment spécifier l'expression de partition](#alter-how-to-specify-part-expr).
-
-The query is replicated – it deletes data on all replicas.
-
-#### DROP DETACHED PARTITION\|PART {#alter_drop-detached}
-
-``` sql
-ALTER TABLE table_name DROP DETACHED PARTITION|PART partition_expr
-```
-
-Supprime la partie spécifiée ou toutes les parties de la partition spécifiée de `detached`.
-En savoir plus sur la définition de l'expression de partition dans une section [Comment spécifier l'expression de partition](#alter-how-to-specify-part-expr).
-
-#### ATTACH PARTITION\|PART {#alter_attach-partition}
-
-``` sql
-ALTER TABLE table_name ATTACH PARTITION|PART partition_expr
-```
-
-Ajoute des données à la table à partir du `detached` répertoire. Il est possible d'ajouter des données dans une partition entière ou pour une partie distincte. Exemple:
-
-``` sql
-ALTER TABLE visits ATTACH PARTITION 201901;
-ALTER TABLE visits ATTACH PART 201901_2_2_0;
-```
-
-En savoir plus sur la définition de l'expression de partition dans une section [Comment spécifier l'expression de partition](#alter-how-to-specify-part-expr).
-
-Cette requête est répliquée. L'initiateur de réplica vérifie s'il y a des données dans le `detached` répertoire. Si des données existent, la requête vérifie son intégrité. Si tout est correct, la requête ajoute les données à la table. Tous les autres réplicas téléchargent les données de l'initiateur de réplica.
-
-Ainsi, vous pouvez mettre des données à la `detached` répertoire sur une réplique, et utilisez le `ALTER ... ATTACH` requête pour l'ajouter à la table sur tous les réplicas.
-
-#### ATTACH PARTITION FROM {#alter_attach-partition-from}
-
-``` sql
-ALTER TABLE table2 ATTACH PARTITION partition_expr FROM table1
-```
-
-Cette requête copie la partition de données du `table1` de `table2` ajoute des données de gratuit dans la `table2`. Notez que les données ne seront pas supprimées de `table1`.
-
-Pour que la requête s'exécute correctement, les conditions suivantes doivent être remplies:
-
--   Les deux tables doivent avoir la même structure.
--   Les deux tables doivent avoir la même clé de partition.
-
-#### REPLACE PARTITION {#alter_replace-partition}
-
-``` sql
-ALTER TABLE table2 REPLACE PARTITION partition_expr FROM table1
-```
-
-Cette requête copie la partition de données du `table1` de `table2` et remplace la partition existante dans le `table2`. Notez que les données ne seront pas supprimées de `table1`.
-
-Pour que la requête s'exécute correctement, les conditions suivantes doivent être remplies:
-
--   Les deux tables doivent avoir la même structure.
--   Les deux tables doivent avoir la même clé de partition.
-
-#### MOVE PARTITION TO TABLE {#alter_move_to_table-partition}
-
-``` sql
-ALTER TABLE table_source MOVE PARTITION partition_expr TO TABLE table_dest
-```
-
-Cette requête déplace la partition de données du `table_source` de `table_dest` avec la suppression des données de `table_source`.
-
-Pour que la requête s'exécute correctement, les conditions suivantes doivent être remplies:
-
--   Les deux tables doivent avoir la même structure.
--   Les deux tables doivent avoir la même clé de partition.
--   Les deux tables doivent appartenir à la même famille de moteurs. (répliqué ou non répliqué)
--   Les deux tables doivent avoir la même stratégie de stockage.
-
-#### CLEAR COLUMN IN PARTITION {#alter_clear-column-partition}
-
-``` sql
-ALTER TABLE table_name CLEAR COLUMN column_name IN PARTITION partition_expr
-```
-
-Réinitialise toutes les valeurs de la colonne spécifiée dans une partition. Si l' `DEFAULT` la clause a été déterminée lors de la création d'une table, cette requête définit la valeur de la colonne à une valeur par défaut spécifiée.
-
-Exemple:
-
-``` sql
-ALTER TABLE visits CLEAR COLUMN hour in PARTITION 201902
-```
-
-#### FREEZE PARTITION {#alter_freeze-partition}
-
-``` sql
-ALTER TABLE table_name FREEZE [PARTITION partition_expr]
-```
-
-Cette requête crée une sauvegarde locale d'une partition spécifiée. Si l' `PARTITION` la clause est omise, la requête crée la sauvegarde de toutes les partitions à la fois.
-
-!!! note "Note"
-    L'ensemble du processus de sauvegarde est effectuée sans arrêter le serveur.
-
-Notez que pour les tables de style ancien, vous pouvez spécifier le préfixe du nom de la partition (par exemple, ‘2019’)- ensuite, la requête crée la sauvegarde pour toutes les partitions correspondantes. Lisez à propos de la définition de l'expression de partition dans une section [Comment spécifier l'expression de partition](#alter-how-to-specify-part-expr).
-
-Au moment de l'exécution, pour un instantané de données, la requête crée des liens rigides vers des données de table. Les liens sont placés dans le répertoire `/var/lib/clickhouse/shadow/N/...`, où:
-
--   `/var/lib/clickhouse/` est le répertoire de travail clickhouse spécifié dans la configuration.
--   `N` est le numéro incrémental de la sauvegarde.
-
-!!! note "Note"
-    Si vous utilisez [un ensemble de disques pour le stockage des données dans une table](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes), le `shadow/N` le répertoire apparaît sur chaque disque, stockant les parties de données correspondant `PARTITION` expression.
-
-La même structure de répertoires est créée à l'intérieur de la sauvegarde qu'à l'intérieur `/var/lib/clickhouse/`. La requête effectue ‘chmod’ pour tous les fichiers, interdisant d'écrire en eux.
-
-Après avoir créé la sauvegarde, vous pouvez copier les données depuis `/var/lib/clickhouse/shadow/` sur le serveur distant, puis supprimez-le du serveur local. Notez que l' `ALTER t FREEZE PARTITION` la requête n'est pas répliqué. Il crée une sauvegarde locale uniquement sur le serveur local.
-
-La requête crée une sauvegarde presque instantanément (mais elle attend d'abord que les requêtes en cours à la table correspondante se terminent).
-
-`ALTER TABLE t FREEZE PARTITION` copie uniquement les données, pas les métadonnées de la table. Faire une sauvegarde des métadonnées de la table, copiez le fichier `/var/lib/clickhouse/metadata/database/table.sql`
-
-Pour restaurer des données à partir d'une sauvegarde, procédez comme suit:
-
-1.  Créer la table si elle n'existe pas. Pour afficher la requête, utilisez la .fichier sql (remplacer `ATTACH` avec `CREATE`).
-2.  Copier les données de la `data/database/table/` répertoire à l'intérieur de la sauvegarde `/var/lib/clickhouse/data/database/table/detached/` répertoire.
-3.  Exécuter `ALTER TABLE t ATTACH PARTITION` les requêtes pour ajouter les données à une table.
-
-La restauration à partir d'une sauvegarde ne nécessite pas l'arrêt du serveur.
-
-Pour plus d'informations sur les sauvegardes et la restauration [La Sauvegarde Des Données](../../operations/backup.md) section.
-
-#### CLEAR INDEX IN PARTITION {#alter_clear-index-partition}
-
-``` sql
-ALTER TABLE table_name CLEAR INDEX index_name IN PARTITION partition_expr
-```
-
-La requête fonctionne de manière similaire à `CLEAR COLUMN` mais il remet un index au lieu d'une colonne de données.
-
-#### FETCH PARTITION {#alter_fetch-partition}
-
-``` sql
-ALTER TABLE table_name FETCH PARTITION partition_expr FROM 'path-in-zookeeper'
-```
-
-Télécharge une partition depuis un autre serveur. Cette requête ne fonctionne que pour les tables répliquées.
-
-La requête effectue les opérations suivantes:
-
-1.  Télécharge la partition à partir du fragment spécifié. Dans ‘path-in-zookeeper’ vous devez spécifier un chemin vers le fragment dans ZooKeeper.
-2.  Ensuite, la requête met les données téléchargées dans le `detached` répertoire de la `table_name` table. L'utilisation de la [ATTACH PARTITION\|PART](#alter_attach-partition) requête pour ajouter les données à la table.
-
-Exemple:
-
-``` sql
-ALTER TABLE users FETCH PARTITION 201902 FROM '/clickhouse/tables/01-01/visits';
-ALTER TABLE users ATTACH PARTITION 201902;
-```
-
-Notez que:
-
--   Le `ALTER ... FETCH PARTITION` la requête n'est pas répliqué. Il place la partition à la `detached` répertoire sur le serveur local.
--   Le `ALTER TABLE ... ATTACH` la requête est répliquée. Il ajoute les données à toutes les répliques. Les données sont ajoutées à l'une des répliques `detached` répertoire, et aux autres-des répliques voisines.
-
-Avant le téléchargement, le système vérifie si la partition existe et si la structure de la table correspond. La réplique la plus appropriée est sélectionnée automatiquement parmi les répliques saines.
-
-Bien que la requête soit appelée `ALTER TABLE`, il ne modifie pas la structure de la table et ne modifie pas immédiatement les données disponibles dans la table.
-
-#### MOVE PARTITION\|PART {#alter_move-partition}
-
-Déplace des partitions ou des parties de données vers un autre volume ou disque pour `MergeTree`-tables de moteur. Voir [Utilisation de plusieurs périphériques de bloc pour le stockage de données](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-multiple-volumes).
-
-``` sql
-ALTER TABLE table_name MOVE PARTITION|PART partition_expr TO DISK|VOLUME 'disk_name'
-```
-
-Le `ALTER TABLE t MOVE` requête:
-
--   Non répliqué, car différentes répliques peuvent avoir des stratégies de stockage différentes.
--   Renvoie une erreur si le disque ou le volume n'est pas configuré. Query renvoie également une erreur si les conditions de déplacement des données, spécifiées dans la stratégie de stockage, ne peuvent pas être appliquées.
--   Peut renvoyer une erreur dans le cas, lorsque les données à déplacer sont déjà déplacées par un processus en arrière-plan, simultané `ALTER TABLE t MOVE` requête ou à la suite de la fusion de données d'arrière-plan. Un utilisateur ne doit effectuer aucune action supplémentaire dans ce cas.
-
-Exemple:
-
-``` sql
-ALTER TABLE hits MOVE PART '20190301_14343_16206_438' TO VOLUME 'slow'
-ALTER TABLE hits MOVE PARTITION '2019-09-01' TO DISK 'fast_ssd'
-```
-
-#### Comment définir L'Expression de la Partition {#alter-how-to-specify-part-expr}
-
-Vous pouvez spécifier l'expression de partition dans `ALTER ... PARTITION` requêtes de différentes manières:
-
--   Comme une valeur de l' `partition` la colonne de la `system.parts` table. Exemple, `ALTER TABLE visits DETACH PARTITION 201901`.
--   Comme expression de la colonne de la table. Les constantes et les expressions constantes sont prises en charge. Exemple, `ALTER TABLE visits DETACH PARTITION toYYYYMM(toDate('2019-01-25'))`.
--   À l'aide de l'ID de partition. Partition ID est un identifiant de chaîne de la partition (lisible par l'homme, si possible) qui est utilisé comme noms de partitions dans le système de fichiers et dans ZooKeeper. L'ID de partition doit être spécifié dans `PARTITION ID` clause, entre guillemets simples. Exemple, `ALTER TABLE visits DETACH PARTITION ID '201901'`.
--   Dans le [ALTER ATTACH PART](#alter_attach-partition) et [DROP DETACHED PART](#alter_drop-detached) requête, pour spécifier le nom d'une partie, utilisez le littéral de chaîne avec une valeur de `name` la colonne de la [système.detached_parts](../../operations/system-tables.md#system_tables-detached_parts) table. Exemple, `ALTER TABLE visits ATTACH PART '201901_1_1_0'`.
-
-L'utilisation de guillemets lors de la spécification de la partition dépend du type d'expression de partition. Par exemple, pour la `String` type, vous devez spécifier son nom entre guillemets (`'`). Pour l' `Date` et `Int*` types aucune citation n'est nécessaire.
-
-Pour les tables de style ancien, vous pouvez spécifier la partition sous forme de nombre `201901` ou une chaîne de caractères `'201901'`. La syntaxe des tables new-style est plus stricte avec les types (similaire à l'analyseur pour le format D'entrée des valeurs).
-
-Toutes les règles ci-dessus sont aussi valables pour la [OPTIMIZE](misc.md#misc_operations-optimize) requête. Si vous devez spécifier la seule partition lors de l'optimisation d'une table non partitionnée, définissez l'expression `PARTITION tuple()`. Exemple:
-
-``` sql
-OPTIMIZE TABLE table_not_partitioned PARTITION tuple() FINAL;
-```
-
-Les exemples de `ALTER ... PARTITION` les requêtes sont démontrées dans les tests [`00502_custom_partitioning_local`](https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/00502_custom_partitioning_local.sql) et [`00502_custom_partitioning_replicated_zookeeper`](https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/00502_custom_partitioning_replicated_zookeeper.sql).
-
-### Manipulations avec Table TTL {#manipulations-with-table-ttl}
-
-Vous pouvez modifier [tableau TTL](../../engines/table-engines/mergetree-family/mergetree.md#mergetree-table-ttl) avec une demande du formulaire suivant:
-
-``` sql
-ALTER TABLE table-name MODIFY TTL ttl-expression
-```
-
-### Synchronicité des requêtes ALTER {#synchronicity-of-alter-queries}
-
-Pour les tables non réplicables, tous `ALTER` les requêtes sont exécutées simultanément. Pour les tables réplicables, la requête ajoute simplement des instructions pour les actions appropriées à `ZooKeeper` et les actions elles-mêmes sont effectuées dès que possible. Cependant, la requête peut attendre que ces actions soient terminées sur tous les réplicas.
-
-Pour `ALTER ... ATTACH|DETACH|DROP` les requêtes, vous pouvez utiliser le `replication_alter_partitions_sync` configuration pour configurer l'attente.
-Valeurs possibles: `0` – do not wait; `1` – only wait for own execution (default); `2` – wait for all.
-
-### Mutation {#alter-mutations}
-
-Les Mutations sont une variante ALTER query qui permet de modifier ou de supprimer des lignes dans une table. Contrairement à la norme `UPDATE` et `DELETE` les requêtes qui sont destinées aux changements de données de point, les mutations sont destinées aux opérations lourdes qui modifient beaucoup de lignes dans une table. Pris en charge pour le `MergeTree` famille de moteurs de table, y compris les moteurs avec support de réplication.
-
-Les tables existantes sont prêtes pour les mutations telles quelles (aucune conversion nécessaire), mais après l'application de la première mutation à une table, son format de métadonnées devient incompatible avec les versions précédentes du serveur et il devient impossible de revenir à une version précédente.
-
-Commandes actuellement disponibles:
-
-``` sql
-ALTER TABLE [db.]table DELETE WHERE filter_expr
-```
-
-Le `filter_expr` doit être de type `UInt8`. La requête supprime les lignes de la table pour lesquelles cette expression prend une valeur différente de zéro.
-
-``` sql
-ALTER TABLE [db.]table UPDATE column1 = expr1 [, ...] WHERE filter_expr
-```
-
-Le `filter_expr` doit être de type `UInt8`. Cette requête met à jour les valeurs des colonnes spécifiées en les valeurs des expressions correspondantes dans les lignes pour lesquelles `filter_expr` prend une valeur non nulle. Les valeurs sont converties en type de colonne à l'aide `CAST` opérateur. La mise à jour des colonnes utilisées dans le calcul de la clé primaire ou de la clé de partition n'est pas prise en charge.
-
-``` sql
-ALTER TABLE [db.]table MATERIALIZE INDEX name IN PARTITION partition_name
-```
-
-La requête reconstruit l'index secondaire `name` dans la partition `partition_name`.
-
-Une requête peut contenir plusieurs commandes séparées par des virgules.
-
-Pour les tables \* MergeTree, les mutations s'exécutent en réécrivant des parties de données entières. Il n'y a pas d'atomicité-les pièces sont substituées aux pièces mutées dès qu'elles sont prêtes et un `SELECT` la requête qui a commencé à s'exécuter pendant une mutation verra les données des parties qui ont déjà été mutées ainsi que les données des parties qui n'ont pas encore été mutées.
-
-Les Mutations sont totalement ordonnées par leur ordre de création et sont appliquées à chaque partie dans cet ordre. Les Mutations sont également partiellement ordonnées avec des insertions - les données insérées dans la table avant la soumission de la mutation seront mutées et les données insérées après ne seront pas mutées. Notez que les mutations ne bloquent en aucune façon les INSERTs.
-
-Une requête de mutation retourne immédiatement après l'ajout de l'entrée de mutation (dans le cas de tables répliquées à ZooKeeper, pour les tables non compliquées - au système de fichiers). La mutation elle-même s'exécute de manière asynchrone en utilisant les paramètres du profil système. Pour suivre l'avancement des mutations vous pouvez utiliser la [`system.mutations`](../../operations/system-tables.md#system_tables-mutations) table. Une mutation qui a été soumise avec succès continuera à s'exécuter même si les serveurs ClickHouse sont redémarrés. Il n'y a aucun moyen de faire reculer la mutation une fois qu'elle est soumise, mais si la mutation est bloquée pour une raison quelconque, elle peut être annulée avec le [`KILL MUTATION`](misc.md#kill-mutation) requête.
-
-Les entrées pour les mutations finies ne sont pas supprimées immédiatement (le nombre d'entrées conservées est déterminé par `finished_mutations_to_keep` le moteur de stockage de paramètre). Les anciennes entrées de mutation sont supprimées.

-# Créer des requêtes {#create-queries}
-
-## CREATE DATABASE {#query-language-create-database}
-
-Crée la base de données.
-
-``` sql
-CREATE DATABASE [IF NOT EXISTS] db_name [ON CLUSTER cluster] [ENGINE = engine(...)]
-```
-
-### Clause {#clauses}
-
--   `IF NOT EXISTS`
-    Si l' `db_name` la base de données existe déjà, alors ClickHouse ne crée pas de nouvelle base de données et:
-
-    -   Ne lance pas d'exception si la clause est spécifiée.
-    -   Lève une exception si la clause n'est pas spécifiée.
-
--   `ON CLUSTER`
-    Clickhouse crée le `db_name` base de données sur tous les serveurs d'un cluster spécifié.
-
--   `ENGINE`
-
-    -   [MySQL](../../engines/database-engines/mysql.md)
-        Vous permet de récupérer des données à partir du serveur MySQL distant.
-        Par défaut, ClickHouse utilise son propre [moteur de base de données](../../engines/database-engines/index.md).
-
-## CREATE TABLE {#create-table-query}
-
-Le `CREATE TABLE` la requête peut avoir plusieurs formes.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [compression_codec] [TTL expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [compression_codec] [TTL expr2],
-    ...
-) ENGINE = engine
-```
-
-Crée une table nommée ‘name’ dans le ‘db’ base de données ou la base de données actuelle si ‘db’ n'est pas définie, avec la structure spécifiée entre parenthèses et l' ‘engine’ moteur.
-La structure de la table est une liste de descriptions de colonnes. Si les index sont pris en charge par le moteur, ils sont indiqués comme paramètres pour le moteur de table.
-
-Une description de colonne est `name type` dans le cas le plus simple. Exemple: `RegionID UInt32`.
-Des Expressions peuvent également être définies pour les valeurs par défaut (voir ci-dessous).
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name AS [db2.]name2 [ENGINE = engine]
-```
-
-Crée une table avec la même structure qu'une autre table. Vous pouvez spécifier un moteur différent pour la table. Si le moteur n'est pas spécifié, le même moteur sera utilisé que pour la `db2.name2` table.
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name AS table_function()
-```
-
-Crée une table avec la structure et les données renvoyées par [fonction de table](../table-functions/index.md#table-functions).
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name ENGINE = engine AS SELECT ...
-```
-
-Crée une table avec une structure comme le résultat de l' `SELECT` une requête avec les ‘engine’ moteur, et le remplit avec des données de SELECT.
-
-Dans tous les cas, si `IF NOT EXISTS` est spécifié, la requête ne renvoie pas une erreur si la table existe déjà. Dans ce cas, la requête ne font rien.
-
-Il peut y avoir d'autres clauses après le `ENGINE` la clause dans la requête. Voir la documentation détaillée sur la façon de créer des tables dans les descriptions de [moteurs de table](../../engines/table-engines/index.md#table_engines).
-
-### Les Valeurs Par Défaut {#create-default-values}
-
-La description de colonne peut spécifier une expression pour une valeur par défaut, de l'une des manières suivantes:`DEFAULT expr`, `MATERIALIZED expr`, `ALIAS expr`.
-Exemple: `URLDomain String DEFAULT domain(URL)`.
-
-Si une expression pour la valeur par défaut n'est pas définie, les valeurs par défaut seront définies sur zéros pour les nombres, chaînes vides pour les chaînes, tableaux vides pour les tableaux et `1970-01-01` pour les dates ou zero unix timestamp pour les dates avec le temps. Les valeurs NULL ne sont pas prises en charge.
-
-Si l'expression par défaut est définie, le type de colonne est facultatif. S'il n'y a pas de type explicitement défini, le type d'expression par défaut est utilisé. Exemple: `EventDate DEFAULT toDate(EventTime)` – the ‘Date’ type sera utilisé pour la ‘EventDate’ colonne.
-
-Si le type de données et l'expression par défaut sont définis explicitement, cette expression sera convertie au type spécifié à l'aide des fonctions de conversion de type. Exemple: `Hits UInt32 DEFAULT 0` signifie la même chose que `Hits UInt32 DEFAULT toUInt32(0)`.
-
-Default expressions may be defined as an arbitrary expression from table constants and columns. When creating and changing the table structure, it checks that expressions don't contain loops. For INSERT, it checks that expressions are resolvable – that all columns they can be calculated from have been passed.
-
-`DEFAULT expr`
-
-Valeur par défaut normale. Si la requête INSERT ne spécifie pas la colonne correspondante, elle sera remplie en calculant l'expression correspondante.
-
-`MATERIALIZED expr`
-
-Expression matérialisée. Une telle colonne ne peut pas être spécifiée pour INSERT, car elle est toujours calculée.
-Pour un INSERT sans Liste de colonnes, ces colonnes ne sont pas prises en compte.
-De plus, cette colonne n'est pas substituée lors de l'utilisation d'un astérisque dans une requête SELECT. C'est pour préserver l'invariant que le dump obtenu en utilisant `SELECT *` peut être inséré dans la table en utilisant INSERT sans spécifier la liste des colonnes.
-
-`ALIAS expr`
-
-Synonyme. Une telle colonne n'est pas du tout stockée dans la table.
-Ses valeurs ne peuvent pas être insérées dans une table et elles ne sont pas substituées lors de l'utilisation d'un astérisque dans une requête SELECT.
-Il peut être utilisé dans SELECTs si l'alias est développé pendant l'analyse des requêtes.
-
-Lorsque vous utilisez la requête ALTER pour ajouter de nouvelles colonnes, les anciennes données de ces colonnes ne sont pas écrites. Au lieu de cela, lors de la lecture d'anciennes données qui n'ont pas de valeurs pour les nouvelles colonnes, les expressions sont calculées à la volée par défaut. Cependant, si l'exécution des expressions nécessite différentes colonnes qui ne sont pas indiquées dans la requête, ces colonnes seront en outre lues, mais uniquement pour les blocs de données qui en ont besoin.
-
-Si vous ajoutez une nouvelle colonne à une table mais modifiez ultérieurement son expression par défaut, les valeurs utilisées pour les anciennes données changeront (pour les données où les valeurs n'ont pas été stockées sur le disque). Notez que lors de l'exécution de fusions d'arrière-plan, les données des colonnes manquantes dans l'une des parties de fusion sont écrites dans la partie fusionnée.
-
-Il n'est pas possible de définir des valeurs par défaut pour les éléments dans les structures de données.
-
-### Contraintes {#constraints}
-
-Avec les descriptions de colonnes des contraintes peuvent être définies:
-
-``` sql
-CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [compression_codec] [TTL expr1],
-    ...
-    CONSTRAINT constraint_name_1 CHECK boolean_expr_1,
-    ...
-) ENGINE = engine
-```
-
-`boolean_expr_1` pourrait par n'importe quelle expression booléenne. Si les contraintes sont définies pour la table, chacun d'eux sera vérifiée pour chaque ligne `INSERT` query. If any constraint is not satisfied — server will raise an exception with constraint name and checking expression.
-
-L'ajout d'une grande quantité de contraintes peut affecter négativement les performances de big `INSERT` requête.
-
-### Expression TTL {#ttl-expression}
-
-Définit la durée de stockage des valeurs. Peut être spécifié uniquement pour les tables mergetree-family. Pour la description détaillée, voir [TTL pour les colonnes et les tableaux](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-ttl).
-
-### Codecs De Compression De Colonne {#codecs}
-
-Par défaut, ClickHouse applique le `lz4` méthode de compression. Pour `MergeTree`- famille de moteurs Vous pouvez modifier la méthode de compression par défaut dans le [compression](../../operations/server-configuration-parameters/settings.md#server-settings-compression) section d'une configuration de serveur. Vous pouvez également définir la méthode de compression pour chaque colonne `CREATE TABLE` requête.
-
-``` sql
-CREATE TABLE codec_example
-(
-    dt Date CODEC(ZSTD),
-    ts DateTime CODEC(LZ4HC),
-    float_value Float32 CODEC(NONE),
-    double_value Float64 CODEC(LZ4HC(9))
-    value Float32 CODEC(Delta, ZSTD)
-)
-ENGINE = <Engine>
-...
-```
-
-Si un codec est spécifié, le codec par défaut ne s'applique pas. Les Codecs peuvent être combinés dans un pipeline, par exemple, `CODEC(Delta, ZSTD)`. Pour sélectionner la meilleure combinaison de codecs pour votre projet, passez des benchmarks similaires à ceux décrits dans Altinity [Nouveaux encodages pour améliorer L'efficacité du ClickHouse](https://www.altinity.com/blog/2019/7/new-encodings-to-improve-clickhouse) article.
-
-!!! warning "Avertissement"
-    Vous ne pouvez pas décompresser les fichiers de base de données ClickHouse avec des utilitaires externes tels que `lz4`. Au lieu de cela, utilisez le spécial [clickhouse-compresseur](https://github.com/ClickHouse/ClickHouse/tree/master/programs/compressor) utilitaire.
-
-La Compression est prise en charge pour les moteurs de tableau suivants:
-
--   [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) famille. Prend en charge les codecs de compression de colonne et la sélection de la méthode de compression par défaut par [compression](../../operations/server-configuration-parameters/settings.md#server-settings-compression) paramètre.
--   [Journal](../../engines/table-engines/log-family/index.md) famille. Utilise le `lz4` méthode de compression par défaut et prend en charge les codecs de compression de colonne.
--   [Définir](../../engines/table-engines/special/set.md). Uniquement pris en charge la compression par défaut.
--   [Rejoindre](../../engines/table-engines/special/join.md). Uniquement pris en charge la compression par défaut.
-
-ClickHouse prend en charge les codecs à usage commun et les codecs spécialisés.
-
-#### Codecs Spécialisés {#create-query-specialized-codecs}
-
-Ces codecs sont conçus pour rendre la compression plus efficace en utilisant des fonctionnalités spécifiques des données. Certains de ces codecs ne compressent pas les données eux-mêmes. Au lieu de cela, ils préparent les données pour un codec à usage commun, qui les compresse mieux que sans cette préparation.
-
-Spécialisé codecs:
-
--   `Delta(delta_bytes)` — Compression approach in which raw values are replaced by the difference of two neighboring values, except for the first value that stays unchanged. Up to `delta_bytes` sont utilisés pour stocker des valeurs delta, donc `delta_bytes` est la taille maximale des valeurs brutes. Possible `delta_bytes` valeurs: 1, 2, 4, 8. La valeur par défaut pour `delta_bytes` être `sizeof(type)` si égale à 1, 2, 4 ou 8. Dans tous les autres cas, c'est 1.
--   `DoubleDelta` — Calculates delta of deltas and writes it in compact binary form. Optimal compression rates are achieved for monotonic sequences with a constant stride, such as time series data. Can be used with any fixed-width type. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. Uses 1 extra bit for 32-byte deltas: 5-bit prefixes instead of 4-bit prefixes. For additional information, see Compressing Time Stamps in [Gorilla: Une Base De Données De Séries Chronologiques Rapide, Évolutive Et En Mémoire](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
--   `Gorilla` — Calculates XOR between current and previous value and writes it in compact binary form. Efficient when storing a series of floating point values that change slowly, because the best compression rate is achieved when neighboring values are binary equal. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. For additional information, see Compressing Values in [Gorilla: Une Base De Données De Séries Chronologiques Rapide, Évolutive Et En Mémoire](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
--   `T64` — Compression approach that crops unused high bits of values in integer data types (including `Enum`, `Date` et `DateTime`). À chaque étape de son algorithme, le codec prend un bloc de 64 valeurs, les place dans une matrice de 64x64 bits, le transpose, recadre les bits de valeurs inutilisés et renvoie le reste sous forme de séquence. Les bits inutilisés sont les bits, qui ne diffèrent pas entre les valeurs maximum et minimum dans la partie de données entière pour laquelle la compression est utilisée.
-
-`DoubleDelta` et `Gorilla` les codecs sont utilisés dans Gorilla TSDB comme composants de son algorithme de compression. L'approche Gorilla est efficace dans les scénarios où il y a une séquence de valeurs qui changent lentement avec leurs horodatages. Les horodatages sont effectivement compressés par le `DoubleDelta` codec, et les valeurs sont effectivement comprimé par le `Gorilla` codec. Par exemple, pour obtenir une table stockée efficacement, vous pouvez la créer dans la configuration suivante:
-
-``` sql
-CREATE TABLE codec_example
-(
-    timestamp DateTime CODEC(DoubleDelta),
-    slow_values Float32 CODEC(Gorilla)
-)
-ENGINE = MergeTree()
-```
-
-#### Codecs À Usage Général {#create-query-general-purpose-codecs}
-
-Codec:
-
--   `NONE` — No compression.
--   `LZ4` — Lossless [algorithme de compression de données](https://github.com/lz4/lz4) utilisé par défaut. Applique la compression rapide LZ4.
--   `LZ4HC[(level)]` — LZ4 HC (high compression) algorithm with configurable level. Default level: 9. Setting `level <= 0` s'applique le niveau par défaut. Niveaux possibles: \[1, 12\]. Plage de niveau recommandée: \[4, 9\].
--   `ZSTD[(level)]` — [Algorithme de compression ZSTD](https://en.wikipedia.org/wiki/Zstandard) avec configurables `level`. Niveaux possibles: \[1, 22\]. Valeur par défaut: 1.
-
-Des niveaux de compression élevés sont utiles pour les scénarios asymétriques, comme compresser une fois, décompresser à plusieurs reprises. Des niveaux plus élevés signifient une meilleure compression et une utilisation plus élevée du processeur.
-
-## Les Tables Temporaires {#temporary-tables}
-
-Clickhouse prend en charge les tables temporaires qui ont les caractéristiques suivantes:
-
--   Les tables temporaires disparaissent à la fin de la session, y compris si la connexion est perdue.
--   Une table temporaire utilise uniquement le moteur de mémoire.
--   La base de données ne peut pas être spécifiée pour une table temporaire. Il est créé en dehors des bases de données.
--   Impossible de créer une table temporaire avec une requête DDL distribuée sur tous les serveurs de cluster (en utilisant `ON CLUSTER`): ce tableau n'existe que dans la session en cours.
--   Si une table temporaire a le même nom qu'une autre et qu'une requête spécifie le nom de la table sans spécifier la base de données, la table temporaire sera utilisée.
--   Pour le traitement des requêtes distribuées, les tables temporaires utilisées dans une requête sont transmises à des serveurs distants.
-
-Pour créer une table temporaire, utilisez la syntaxe suivante:
-
-``` sql
-CREATE TEMPORARY TABLE [IF NOT EXISTS] table_name
-(
-    name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
-    name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
-    ...
-)
-```
-
-Dans la plupart des cas, les tables temporaires ne sont pas créées manuellement, mais lors de l'utilisation de données externes pour une requête ou pour `(GLOBAL) IN`. Pour plus d'informations, consultez les sections appropriées
-
-Il est possible d'utiliser des tables avec [Moteur = mémoire](../../engines/table-engines/special/memory.md) au lieu de tables temporaires.
-
-## Requêtes DDL distribuées (sur la clause CLUSTER) {#distributed-ddl-queries-on-cluster-clause}
-
-Le `CREATE`, `DROP`, `ALTER`, et `RENAME` les requêtes prennent en charge l'exécution distribuée sur un cluster.
-Par exemple, la requête suivante crée la `all_hits` `Distributed` tableau sur chaque ordinateur hôte `cluster`:
-
-``` sql
-CREATE TABLE IF NOT EXISTS all_hits ON CLUSTER cluster (p Date, i Int32) ENGINE = Distributed(cluster, default, hits)
-```
-
-Pour exécuter ces requêtes correctement, chaque hôte doit avoir la même définition de cluster (pour simplifier la synchronisation des configs, vous pouvez utiliser des substitutions de ZooKeeper). Ils doivent également se connecter aux serveurs ZooKeeper.
-La version locale de la requête sera finalement implémentée sur chaque hôte du cluster, même si certains hôtes ne sont actuellement pas disponibles. L'ordre d'exécution des requêtes au sein d'un seul hôte est garanti.
-
-## CREATE VIEW {#create-view}
-
-``` sql
-CREATE [MATERIALIZED] VIEW [IF NOT EXISTS] [db.]table_name [TO[db.]name] [ENGINE = engine] [POPULATE] AS SELECT ...
-```
-
-Crée une vue. Il existe deux types de vues: normale et matérialisée.
-
-Les vues normales ne stockent aucune donnée, mais effectuent simplement une lecture à partir d'une autre table. En d'autres termes, une vue normale n'est rien de plus qu'une requête enregistrée. Lors de la lecture à partir d'une vue, cette requête enregistrée est utilisée comme sous-requête dans la clause FROM.
-
-Par exemple, supposons que vous avez créé une vue:
-
-``` sql
-CREATE VIEW view AS SELECT ...
-```
-
-et écrit une requête:
-
-``` sql
-SELECT a, b, c FROM view
-```
-
-Cette requête est entièrement équivalente à l'utilisation de la sous requête:
-
-``` sql
-SELECT a, b, c FROM (SELECT ...)
-```
-
-Les vues matérialisées stockent les données transformées par la requête SELECT correspondante.
-
-Lors de la création d'une vue matérialisée sans `TO [db].[table]`, you must specify ENGINE – the table engine for storing data.
-
-Lors de la création d'une vue matérialisée avec `TO [db].[table]` vous ne devez pas utiliser `POPULATE`.
-
-Une vue matérialisée est agencée comme suit: lors de l'insertion de données dans la table spécifiée dans SELECT, une partie des données insérées est convertie par cette requête SELECT, et le résultat est inséré dans la vue.
-
-Si vous spécifiez POPULATE, les données de table existantes sont insérées dans la vue lors de sa création, comme si `CREATE TABLE ... AS SELECT ...` . Sinon, la requête ne contient que les données insérées dans la table après la création de la vue. Nous ne recommandons pas D'utiliser POPULATE, car les données insérées dans la table lors de la création de la vue ne seront pas insérées dedans.
-
-A `SELECT` la requête peut contenir `DISTINCT`, `GROUP BY`, `ORDER BY`, `LIMIT`… Note that the corresponding conversions are performed independently on each block of inserted data. For example, if `GROUP BY` est définie, les données sont agrégées lors de l'insertion, mais uniquement dans un seul paquet de données insérées. Les données ne seront pas agrégées davantage. L'exception concerne l'utilisation d'un moteur qui effectue indépendamment l'agrégation de données, par exemple `SummingMergeTree`.
-
-L'exécution de `ALTER` les requêtes sur les vues matérialisées n'ont pas été complètement développées, elles pourraient donc être gênantes. Si la vue matérialisée utilise la construction `TO [db.]name` vous pouvez `DETACH` la vue, exécutez `ALTER` pour la table cible, puis `ATTACH` précédemment détaché (`DETACH`) vue.
-
-Les vues ressemblent aux tables normales. Par exemple, ils sont répertoriés dans le résultat de la `SHOW TABLES` requête.
-
-Il n'y a pas de requête séparée pour supprimer des vues. Pour supprimer une vue, utilisez `DROP TABLE`.
-
-## CREATE DICTIONARY {#create-dictionary-query}
-
-``` sql
-CREATE DICTIONARY [IF NOT EXISTS] [db.]dictionary_name [ON CLUSTER cluster]
-(
-    key1 type1  [DEFAULT|EXPRESSION expr1] [HIERARCHICAL|INJECTIVE|IS_OBJECT_ID],
-    key2 type2  [DEFAULT|EXPRESSION expr2] [HIERARCHICAL|INJECTIVE|IS_OBJECT_ID],
-    attr1 type2 [DEFAULT|EXPRESSION expr3],
-    attr2 type2 [DEFAULT|EXPRESSION expr4]
-)
-PRIMARY KEY key1, key2
-SOURCE(SOURCE_NAME([param1 value1 ... paramN valueN]))
-LAYOUT(LAYOUT_NAME([param_name param_value]))
-LIFETIME({MIN min_val MAX max_val | max_val})
-```
-
-Crée [externe dictionnaire](../../sql-reference/dictionaries/external-dictionaries/external-dicts.md) avec le [structure](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-structure.md), [source](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-sources.md), [disposition](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-layout.md) et [vie](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-lifetime.md).
-
-Structure de dictionnaire externe se compose d'attributs. Les attributs du dictionnaire sont spécifiés de la même manière que les colonnes du tableau. La seule propriété d'attribut requise est son type, toutes les autres propriétés peuvent avoir des valeurs par défaut.
-
-Selon le dictionnaire [disposition](../../sql-reference/dictionaries/external-dictionaries/external-dicts-dict-layout.md) un ou plusieurs attributs peuvent être spécifiés comme les clés de dictionnaire.
-
-Pour plus d'informations, voir [Dictionnaires Externes](../dictionaries/external-dictionaries/external-dicts.md) section.
-
-## CREATE USER {#create-user-statement}
-
-Crée un [compte d'utilisateur](../../operations/access-rights.md#user-account-management).
-
-### Syntaxe {#create-user-syntax}
-
-``` sql
-CREATE USER [IF NOT EXISTS | OR REPLACE] name [ON CLUSTER cluster_name]
-    [IDENTIFIED [WITH {NO_PASSWORD|PLAINTEXT_PASSWORD|SHA256_PASSWORD|SHA256_HASH|DOUBLE_SHA1_PASSWORD|DOUBLE_SHA1_HASH}] BY {'password'|'hash'}]
-    [HOST {LOCAL | NAME 'name' | REGEXP 'name_regexp' | IP 'address' | LIKE 'pattern'} [,...] | ANY | NONE]
-    [DEFAULT ROLE role [,...]]
-    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [READONLY|WRITABLE] | PROFILE 'profile_name'] [,...]
-```
-
-#### Identification {#identification}
-
-Il existe de multiples façons d'identification d'un utilisateur:
-
--   `IDENTIFIED WITH no_password`
--   `IDENTIFIED WITH plaintext_password BY 'qwerty'`
--   `IDENTIFIED WITH sha256_password BY 'qwerty'` ou `IDENTIFIED BY 'password'`
--   `IDENTIFIED WITH sha256_hash BY 'hash'`
--   `IDENTIFIED WITH double_sha1_password BY 'qwerty'`
--   `IDENTIFIED WITH double_sha1_hash BY 'hash'`
-
-#### L'Utilisateur De L'Hôte {#user-host}
-
-L'hôte utilisateur est un hôte à partir duquel une connexion au serveur ClickHouse peut être établie. Hôte peut être spécifié dans le `HOST` section de requête par les moyens suivants:
-
--   `HOST IP 'ip_address_or_subnetwork'` — User can connect to ClickHouse server only from the specified IP address or a [sous-réseau](https://en.wikipedia.org/wiki/Subnetwork). Exemple: `HOST IP '192.168.0.0/16'`, `HOST IP '2001:DB8::/32'`. Pour une utilisation en production, spécifiez uniquement `HOST IP` (adresses IP et leurs masques), depuis l'utilisation `host` et `host_regexp` peut causer une latence supplémentaire.
--   `HOST ANY` — User can connect from any location. This is default option.
--   `HOST LOCAL` — User can connect only locally.
--   `HOST NAME 'fqdn'` — User host can be specified as FQDN. For example, `HOST NAME 'mysite.com'`.
--   `HOST NAME REGEXP 'regexp'` — You can use [pcre](http://www.pcre.org/) expressions régulières lors de la spécification des hôtes utilisateur. Exemple, `HOST NAME REGEXP '.*\.mysite\.com'`.
--   `HOST LIKE 'template'` — Allows you use the [LIKE](../functions/string-search-functions.md#function-like) opérateur de filtre de l'utilisateur hôtes. Exemple, `HOST LIKE '%'` est équivalent à `HOST ANY`, `HOST LIKE '%.mysite.com'` filtre tous les hôtes dans le `mysite.com` domaine.
-
-Une autre façon de spécifier l'hôte est d'utiliser `@` syntaxe avec le nom d'utilisateur. Exemple:
-
--   `CREATE USER mira@'127.0.0.1'` — Equivalent to the `HOST IP` syntaxe.
--   `CREATE USER mira@'localhost'` — Equivalent to the `HOST LOCAL` syntaxe.
--   `CREATE USER mira@'192.168.%.%'` — Equivalent to the `HOST LIKE` syntaxe.
-
-!!! info "Avertissement"
-    Clickhouse traite `user_name@'address'` comme un nom d'utilisateur dans son ensemble. Donc, techniquement, vous pouvez créer plusieurs utilisateurs avec `user_name` et différentes constructions après `@`. Nous ne recommandons pas de le faire.
-
-### Exemple {#create-user-examples}
-
-Créer le compte d'utilisateur `mira` protégé par le mot de passe `qwerty`:
-
-``` sql
-CREATE USER mira HOST IP '127.0.0.1' IDENTIFIED WITH sha256_password BY 'qwerty'
-```
-
-`mira` devrait démarrer l'application client sur l'hôte où le serveur ClickHouse s'exécute.
-
-Créer le compte d'utilisateur `john`, attribuez-lui des rôles et définissez ces rôles par défaut:
-
-``` sql
-CREATE USER john DEFAULT ROLE role1, role2
-```
-
-Créer le compte d'utilisateur `john` et faire tous ses futurs rôles par défaut:
-
-``` sql
-ALTER USER user DEFAULT ROLE ALL
-```
-
-Quand un rôle sera attribué à `john` dans l'avenir, il deviendra automatiquement par défaut.
-
-Créer le compte d'utilisateur `john` et faire tous ses futurs rôles par défaut sauf `role1` et `role2`:
-
-``` sql
-ALTER USER john DEFAULT ROLE ALL EXCEPT role1, role2
-```
-
-## CREATE ROLE {#create-role-statement}
-
-Crée un [rôle](../../operations/access-rights.md#role-management).
-
-### Syntaxe {#create-role-syntax}
-
-``` sql
-CREATE ROLE [IF NOT EXISTS | OR REPLACE] name
-    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [READONLY|WRITABLE] | PROFILE 'profile_name'] [,...]
-```
-
-### Description {#create-role-description}
-
-Rôle est un ensemble de [privilège](grant.md#grant-privileges). Un utilisateur reçoit un rôle obtient tous les privilèges de ce rôle.
-
-Un utilisateur peut être affecté à plusieurs rôles. Les utilisateurs peuvent appliquer leurs rôles accordés dans des combinaisons arbitraires par le [SET ROLE](misc.md#set-role-statement) déclaration. La finale de la portée des privilèges est un ensemble combiné de tous les privilèges de tous les rôles. Si un utilisateur a des privilèges accordés directement à son compte d'utilisateur, ils sont également combinés avec les privilèges accordés par les rôles.
-
-L'utilisateur peut avoir des rôles par défaut qui s'appliquent à la connexion de l'utilisateur. Pour définir les rôles par défaut, utilisez [SET DEFAULT ROLE](misc.md#set-default-role-statement) - déclaration ou de la [ALTER USER](alter.md#alter-user-statement) déclaration.
-
-Pour révoquer un rôle, utilisez [REVOKE](revoke.md) déclaration.
-
-Pour supprimer le rôle, utilisez [DROP ROLE](misc.md#drop-role-statement) déclaration. Le rôle supprimé est automatiquement révoqué de tous les utilisateurs et rôles auxquels il a été accordé.
-
-### Exemple {#create-role-examples}
-
-``` sql
-CREATE ROLE accountant;
-GRANT SELECT ON db.* TO accountant;
-```
-
-Cette séquence de requêtes crée le rôle `accountant` cela a le privilège de lire les données du `accounting` la base de données.
-
-Octroi du rôle à l'utilisateur `mira`:
-
-``` sql
-GRANT accountant TO mira;
-```
-
-Une fois le rôle accordé, l'utilisateur peut l'utiliser et effectuer les requêtes autorisées. Exemple:
-
-``` sql
-SET ROLE accountant;
-SELECT * FROM db.*;
-```
-
-## CREATE ROW POLICY {#create-row-policy-statement}
-
-Crée un [filtre pour les lignes](../../operations/access-rights.md#row-policy-management) qu'un utilisateur peut lire à partir d'une table.
-
-### Syntaxe {#create-row-policy-syntax}
-
-``` sql
-CREATE [ROW] POLICY [IF NOT EXISTS | OR REPLACE] policy_name [ON CLUSTER cluster_name] ON [db.]table
-    [AS {PERMISSIVE | RESTRICTIVE}]
-    [FOR SELECT]
-    [USING condition]
-    [TO {role [,...] | ALL | ALL EXCEPT role [,...]}]
-```

-
-À l'aide de cette section, vous pouvez créer des stratégies permissives ou restrictives.
-
-La stratégie Permissive accorde l'accès aux lignes. Les stratégies permissives qui s'appliquent à la même table sont combinées ensemble en utilisant le booléen `OR` opérateur. Les stratégies sont permissives par défaut.
-
-La politique Restrictive limite l'accès à la ligne. Les politiques restrictives qui s'appliquent à la même table sont combinées en utilisant le booléen `AND` opérateur.
-
-Les stratégies restrictives s'appliquent aux lignes qui ont passé les filtres permissifs. Si vous définissez des stratégies restrictives mais aucune politique permissive, l'utilisateur ne peut obtenir aucune ligne de la table.
-
-#### La Section DE {#create-row-policy-to}
-
-Dans la section `TO` vous pouvez donner une liste mixte de rôles et d'utilisateurs, par exemple, `CREATE ROW POLICY ... TO accountant, john@localhost`.
-
-Mot `ALL` signifie Tous les utilisateurs de ClickHouse, y compris l'utilisateur actuel. Mot `ALL EXCEPT` autoriser à exclure certains utilisateurs de la liste tous les utilisateurs, par exemple `CREATE ROW POLICY ... TO ALL EXCEPT accountant, john@localhost`
-
-### Exemple {#examples}
-
--   `CREATE ROW POLICY filter ON mydb.mytable FOR SELECT USING a<1000 TO accountant, john@localhost`
--   `CREATE ROW POLICY filter ON mydb.mytable FOR SELECT USING a<1000 TO ALL EXCEPT mira`
-
-## CREATE QUOTA {#create-quota-statement}
-
-Crée un [quota](../../operations/access-rights.md#quotas-management) qui peut être attribué à un utilisateur ou un rôle.
-
-### Syntaxe {#create-quota-syntax}
-
-``` sql
-CREATE QUOTA [IF NOT EXISTS | OR REPLACE] name [ON CLUSTER cluster_name]
-    [KEYED BY {'none' | 'user name' | 'ip address' | 'client key' | 'client key or user name' | 'client key or ip address'}]
-    [FOR [RANDOMIZED] INTERVAL number {SECOND | MINUTE | HOUR | DAY | WEEK | MONTH | QUARTER | YEAR}
-        {MAX { {QUERIES | ERRORS | RESULT ROWS | RESULT BYTES | READ ROWS | READ BYTES | EXECUTION TIME} = number } [,...] |
-         NO LIMITS | TRACKING ONLY} [,...]]
-    [TO {role [,...] | ALL | ALL EXCEPT role [,...]}]
-```
-
-### Exemple {#create-quota-example}
-
-Limiter le nombre maximum de requêtes pour l'utilisateur actuel avec 123 requêtes en 15 mois contrainte:
-
-``` sql
-CREATE QUOTA qA FOR INTERVAL 15 MONTH MAX QUERIES 123 TO CURRENT_USER
-```
-
-## CREATE SETTINGS PROFILE {#create-settings-profile-statement}
-
-Crée un [les paramètres de profil](../../operations/access-rights.md#settings-profiles-management) qui peut être attribué à un utilisateur ou un rôle.
-
-### Syntaxe {#create-settings-profile-syntax}
-
-``` sql
-CREATE SETTINGS PROFILE [IF NOT EXISTS | OR REPLACE] name [ON CLUSTER cluster_name]
-    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [READONLY|WRITABLE] | INHERIT 'profile_name'] [,...]
-```
-
-# Exemple {#create-settings-profile-syntax}
-
-Créer l' `max_memory_usage_profile` paramètres du profil avec valeur et contraintes pour `max_memory_usage` paramètre. L'affecter à `robin`:
-
-``` sql
-CREATE SETTINGS PROFILE max_memory_usage_profile SETTINGS max_memory_usage = 100000001 MIN 90000000 MAX 110000000 TO robin
-```

-# GRANT {#grant}
-
--   Accorder [privilège](#grant-privileges) pour ClickHouse comptes d'utilisateurs ou des rôles.
--   Affecte des rôles à des comptes d'utilisateurs ou à d'autres rôles.
-
-Pour révoquer les privilèges, utilisez [REVOKE](revoke.md) déclaration. Vous pouvez également classer les privilèges accordés par le [SHOW GRANTS](show.md#show-grants-statement) déclaration.
-
-## Accorder La Syntaxe Des Privilèges {#grant-privigele-syntax}
-
-``` sql
-GRANT [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} TO {user | role | CURRENT_USER} [,...] [WITH GRANT OPTION]
-```
-
--   `privilege` — Type of privilege.
--   `role` — ClickHouse user role.
--   `user` — ClickHouse user account.
-
-Le `WITH GRANT OPTION` clause de subventions `user` ou `role` avec l'autorisation de réaliser des `GRANT` requête. Les utilisateurs peuvent accorder des privilèges de la même portée qu'ils ont et moins.
-
-## Attribution De La Syntaxe Du Rôle {#assign-role-syntax}
-
-``` sql
-GRANT [ON CLUSTER cluster_name] role [,...] TO {user | another_role | CURRENT_USER} [,...] [WITH ADMIN OPTION]
-```
-
--   `role` — ClickHouse user role.
--   `user` — ClickHouse user account.
-
-Le `WITH ADMIN OPTION` clause de jeux [ADMIN OPTION](#admin-option-privilege) privilège pour `user` ou `role`.
-
-## Utilisation {#grant-usage}
-
-Utiliser `GRANT` votre compte doit avoir le `GRANT OPTION` privilège. Vous ne pouvez accorder des privilèges que dans le cadre de vos privilèges de Compte.
-
-Par exemple, l'administrateur a accordé des privilèges `john` compte par la requête:
-
-``` sql
-GRANT SELECT(x,y) ON db.table TO john WITH GRANT OPTION
-```
-
-Cela signifie que `john` a la permission d'effectuer:
-
--   `SELECT x,y FROM db.table`.
--   `SELECT x FROM db.table`.
--   `SELECT y FROM db.table`.
-
-`john` ne pouvez pas effectuer de `SELECT z FROM db.table`. Le `SELECT * FROM db.table` aussi n'est pas disponible. En traitant cette requête, ClickHouse ne renvoie aucune donnée, même `x` et `y`. La seule exception est si une table contient uniquement `x` et `y` colonnes, dans ce cas ClickHouse renvoie toutes les données.
-
-Également `john` a l' `GRANT OPTION` privilège, de sorte qu'il peut accorder à d'autres utilisateurs avec des privilèges de la même ou de la plus petite portée.
-
-Spécification des privilèges vous pouvez utiliser asterisk (`*`) au lieu d'une table ou d'un nom de base de données. Par exemple, l' `GRANT SELECT ON db.* TO john` requête permet `john` pour effectuer la `SELECT` requête sur toutes les tables dans `db` la base de données. En outre, vous pouvez omettre le nom de la base de données. Dans ce cas, des privilèges sont accordés pour la base de données actuelle, par exemple: `GRANT SELECT ON * TO john` accorde le privilège sur toutes les tables dans la base de données actuelle, `GRANT SELECT ON mytable TO john` accorde le privilège sur le `mytable` table dans la base de données actuelle.
-
-L'accès à la `system` la base de données est toujours autorisée (puisque cette base de données est utilisée pour traiter les requêtes).
-
-Vous pouvez accorder plusieurs privilèges à plusieurs comptes dans une requête. Requête `GRANT SELECT, INSERT ON *.* TO john, robin` permet de comptes `john` et `robin` pour effectuer la `INSERT` et `SELECT` des requêtes sur toutes les tables de toutes les bases de données sur le serveur.
-
-## Privilège {#grant-privileges}
-
-Privilège est une autorisation pour effectuer un type spécifique de requêtes.
-
-Les privilèges ont une structure hiérarchique. Un ensemble de requêtes autorisées dépend de la portée des privilèges.
-
-Hiérarchie des privilèges:
-
--   [SELECT](#grant-select)

-
-Exemples de la façon dont cette hiérarchie est traitée:
-
--   Le `ALTER` privilège comprend tous les autres `ALTER*` privilège.
--   `ALTER CONSTRAINT` comprendre `ALTER ADD CONSTRAINT` et `ALTER DROP CONSTRAINT` privilège.
-
-Les privilèges sont appliqués à différents niveaux. Connaissant un niveau suggère la syntaxe disponible pour le privilège.
-
-Les niveaux (du plus faible au plus élevé):
-
--   `COLUMN` — Privilege can be granted for column, table, database, or globally.
--   `TABLE` — Privilege can be granted for table, database, or globally.
--   `VIEW` — Privilege can be granted for view, database, or globally.
--   `DICTIONARY` — Privilege can be granted for dictionary, database, or globally.
--   `DATABASE` — Privilege can be granted for database or globally.
--   `GLOBAL` — Privilege can be granted only globally.
--   `GROUP` — Groups privileges of different levels. When `GROUP`- le privilège de niveau est accordé, seuls les privilèges du groupe sont accordés qui correspondent à la syntaxe utilisée.
-
-Exemples de syntaxe:
-
--   `GRANT SELECT(x) ON db.table TO user`
--   `GRANT SELECT ON db.* TO user`
-
-Exemples de syntaxe refusée:
-
--   `GRANT CREATE USER(x) ON db.table TO user`
--   `GRANT CREATE USER ON db.* TO user`
-
-Le privilège spécial [ALL](#grant-all) accorde tous les privilèges à un compte d'utilisateur ou à un rôle.
-
-Par défaut, un compte d'utilisateur ou un rôle a pas de privilèges.
-
-Si un utilisateur ou un rôle ont pas de privilèges qu'il s'affiche comme [NONE](#grant-none) privilège.
-
-Certaines requêtes par leur implémentation nécessitent un ensemble de privilèges. Par exemple, pour effectuer la [RENAME](misc.md#misc_operations-rename) requête vous avez besoin des privilèges suivants: `SELECT`, `CREATE TABLE`, `INSERT` et `DROP TABLE`.
-
-### SELECT {#grant-select}
-
-Permet d'effectuer des [SELECT](select/index.md) requête.
-
-Le niveau de privilège: `COLUMN`.
-
-**Description**
-
-L'utilisateur accordé avec ce privilège peut effectuer `SELECT` requêtes sur une liste spécifiée de colonnes dans la table et la base de données spécifiées. Si l'utilisateur inclut d'autres colonnes, une requête ne renvoie aucune donnée.
-
-Considérez le privilège suivant:
-
-``` sql
-GRANT SELECT(x,y) ON db.table TO john
-```
-
-Ce privilège permet à `john` pour effectuer toute `SELECT` requête qui implique des données du `x` et/ou `y` les colonnes en `db.table`. Exemple, `SELECT x FROM db.table`. `john` ne pouvez pas effectuer de `SELECT z FROM db.table`. Le `SELECT * FROM db.table` aussi n'est pas disponible. En traitant cette requête, ClickHouse ne renvoie aucune donnée, même `x` et `y`. La seule exception est si une table contient uniquement `x` et `y` colonnes, dans ce cas ClickHouse renvoie toutes les données.
-
-### INSERT {#grant-insert}
-
-Permet d'effectuer des [INSERT](insert-into.md) requête.

-
-**Exemple**
-
-``` sql
-GRANT INSERT(x,y) ON db.table TO john

----
-
-## INSERT {#insert}
-
-L'ajout de données.
-
-Format de requête de base:
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] VALUES (v11, v12, v13), (v21, v22, v23), ...
-```
-
-La requête peut spécifier une liste de colonnes à insérer `[(c1, c2, c3)]`. Dans ce cas, le reste des colonnes sont remplis avec:
-
--   Les valeurs calculées à partir `DEFAULT` expressions spécifiées dans la définition de la table.
--   Zéros et chaînes vides, si `DEFAULT` les expressions ne sont pas définies.
-
-Si [strict_insert_defaults=1](../../operations/settings/settings.md), les colonnes qui n'ont pas `DEFAULT` défini doit être répertorié dans la requête.
-
-Les données peuvent être transmises à L'INSERT dans n'importe quel [format](../../interfaces/formats.md#formats) soutenu par ClickHouse. Le format doit être spécifié explicitement dans la requête:
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] FORMAT format_name data_set
-```
-
-For example, the following query format is identical to the basic version of INSERT … VALUES:
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] FORMAT Values (v11, v12, v13), (v21, v22, v23), ...
-```
-
-ClickHouse supprime tous les espaces et un saut de ligne (s'il y en a un) avant les données. Lors de la formation d'une requête, nous recommandons de placer les données sur une nouvelle ligne après les opérateurs de requête (ceci est important si les données commencent par des espaces).
-
-Exemple:
-
-``` sql
-INSERT INTO t FORMAT TabSeparated
-11  Hello, world!
-22  Qwerty
-```
-
-Vous pouvez insérer des données séparément de la requête à l'aide du client de ligne de commande ou de L'interface HTTP. Pour plus d'informations, consultez la section “[Interface](../../interfaces/index.md#interfaces)”.
-
-### Contraintes {#constraints}
-
-Si la table a [contraintes](create.md#constraints), their expressions will be checked for each row of inserted data. If any of those constraints is not satisfied — server will raise an exception containing constraint name and expression, the query will be stopped.
-
-### Insertion des résultats de `SELECT` {#insert_query_insert-select}
-
-``` sql
-INSERT INTO [db.]table [(c1, c2, c3)] SELECT ...
-```
-
-Les colonnes sont mappées en fonction de leur position dans la clause SELECT. Cependant, leurs noms dans L'expression SELECT et la table pour INSERT peuvent différer. Si nécessaire, la coulée de type est effectuée.
-
-Aucun des formats de données à l'exception des Valeurs permettent de définir des valeurs d'expressions telles que `now()`, `1 + 2` et ainsi de suite. Le format des valeurs permet une utilisation limitée des expressions, mais ce n'est pas recommandé, car dans ce cas, un code inefficace est utilisé pour leur exécution.
-
-Les autres requêtes de modification des parties de données ne sont pas prises en charge: `UPDATE`, `DELETE`, `REPLACE`, `MERGE`, `UPSERT`, `INSERT UPDATE`.
-Cependant, vous pouvez supprimer les anciennes données en utilisant `ALTER TABLE ... DROP PARTITION`.
-
-`FORMAT` la clause doit être spécifié à la fin de la requête si `SELECT` la clause contient la fonction de table [entrée()](../table-functions/input.md).
-
-### Considérations De Performance {#performance-considerations}
-
-`INSERT` trie les données d'entrée par la clé primaire et les divise en partitions par une clé de partition. Si vous insérez des données dans plusieurs partitions à la fois, cela peut réduire considérablement les performances de l' `INSERT` requête. Pour éviter cela:
-
--   Ajoutez des données en lots assez importants, tels que 100 000 lignes à la fois.
--   Groupez les données par une clé de partition avant de les télécharger sur ClickHouse.
-
-Les performances ne diminueront pas si:
-
--   Les données sont ajoutées en temps réel.
--   Vous téléchargez des données qui sont généralement triées par heure.

-# Diverses Requêtes {#miscellaneous-queries}
-
-## ATTACH {#attach}
-
-Cette requête est exactement la même que `CREATE`, mais
-
--   Au lieu de la parole `CREATE` il utilise le mot `ATTACH`.
--   La requête ne crée pas de données sur le disque, mais suppose que les données sont déjà aux endroits appropriés, et ajoute simplement des informations sur la table au serveur.
-    Après avoir exécuté une requête ATTACH, le serveur connaîtra l'existence de la table.
-
-Si la table a été précédemment détachée (`DETACH`), ce qui signifie que sa structure est connue, vous pouvez utiliser un raccourci sans définir la structure.
-
-``` sql
-ATTACH TABLE [IF NOT EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Cette requête est utilisée lors du démarrage du serveur. Le serveur stocke les métadonnées de la table sous forme de fichiers avec `ATTACH` requêtes, qu'il exécute simplement au lancement (à l'exception des tables système, qui sont explicitement créées sur le serveur).
-
-## CHECK TABLE {#check-table}
-
-Vérifie si les données de la table sont corrompues.
-
-``` sql
-CHECK TABLE [db.]name
-```
-
-Le `CHECK TABLE` requête compare réelle des tailles de fichier avec les valeurs attendues qui sont stockés sur le serveur. Si le fichier tailles ne correspondent pas aux valeurs stockées, cela signifie que les données sont endommagées. Cela peut être causé, par exemple, par un plantage du système lors de l'exécution de la requête.
-
-La réponse de la requête contient `result` colonne avec une seule ligne. La ligne a une valeur de
-[Booléen](../../sql-reference/data-types/boolean.md) type:
-
--   0 - les données de la table sont corrompues.
--   1 - les données maintiennent l'intégrité.
-
-Le `CHECK TABLE` query prend en charge les moteurs de table suivants:
-
--   [Journal](../../engines/table-engines/log-family/log.md)
--   [TinyLog](../../engines/table-engines/log-family/tinylog.md)
--   [StripeLog](../../engines/table-engines/log-family/stripelog.md)
--   [Famille MergeTree](../../engines/table-engines/mergetree-family/mergetree.md)
-
-Effectué sur les tables avec un autre moteur de table provoque une exception.
-
-Les moteurs de la `*Log` la famille ne fournit pas de récupération automatique des données en cas d'échec. L'utilisation de la `CHECK TABLE` requête pour suivre la perte de données en temps opportun.
-
-Pour `MergeTree` moteurs de la famille, le `CHECK TABLE` query affiche un État de vérification pour chaque partie de données individuelle d'une table sur le serveur local.
-
-**Si les données sont corrompues**
-
-Si la table est corrompue, vous pouvez copier les données non corrompues dans une autre table. Pour ce faire:
-
-1.  Créez une nouvelle table avec la même structure que la table endommagée. Pour ce faire exécutez la requête `CREATE TABLE <new_table_name> AS <damaged_table_name>`.
-2.  Définir le [max_threads](../../operations/settings/settings.md#settings-max_threads) la valeur 1 pour traiter la requête suivante dans un seul thread. Pour ce faire, exécutez la requête `SET max_threads = 1`.
-3.  Exécuter la requête `INSERT INTO <new_table_name> SELECT * FROM <damaged_table_name>`. Cette demande copie les données non corrompues de la table endommagée vers une autre table. Seules les données avant la partie corrompue seront copiées.
-4.  Redémarrez l' `clickhouse-client` pour réinitialiser l' `max_threads` valeur.
-
-## DESCRIBE TABLE {#misc-describe-table}
-
-``` sql
-DESC|DESCRIBE TABLE [db.]table [INTO OUTFILE filename] [FORMAT format]
-```
-
-Renvoie ce qui suit `String` les colonnes de type:
-
--   `name` — Column name.
--   `type`— Column type.
--   `default_type` — Clause that is used in [expression par défaut](create.md#create-default-values) (`DEFAULT`, `MATERIALIZED` ou `ALIAS`). Column contient une chaîne vide, si l'expression par défaut n'est pas spécifiée.
--   `default_expression` — Value specified in the `DEFAULT` clause.
--   `comment_expression` — Comment text.
-
-Les structures de données imbriquées sont sorties dans “expanded” format. Chaque colonne est affichée séparément, avec le nom après un point.
-
-## DETACH {#detach}
-
-Supprime les informations sur le ‘name’ table du serveur. Le serveur cesse de connaître l'existence de la table.
-
-``` sql
-DETACH TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Cela ne supprime pas les données ou les métadonnées de la table. Lors du prochain lancement du serveur, le serveur Lira les métadonnées et découvrira à nouveau la table.
-De même, un “detached” tableau peut être re-attaché en utilisant le `ATTACH` requête (à l'exception des tables système, qui n'ont pas de stocker les métadonnées pour eux).
-
-Il n'y a pas de `DETACH DATABASE` requête.
-
-## DROP {#drop}
-
-Cette requête a deux types: `DROP DATABASE` et `DROP TABLE`.
-
-``` sql
-DROP DATABASE [IF EXISTS] db [ON CLUSTER cluster]
-```
-
-Supprime toutes les tables à l'intérieur de la ‘db’ la base de données, puis supprime le ‘db’ la base de données elle-même.
-Si `IF EXISTS` est spécifié, il ne renvoie pas d'erreur si la base de données n'existe pas.
-
-``` sql
-DROP [TEMPORARY] TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Supprime la table.
-Si `IF EXISTS` est spécifié, il ne renvoie pas d'erreur si la table n'existe pas ou si la base de données n'existe pas.
-
-    DROP DICTIONARY [IF EXISTS] [db.]name
-
-Delets le dictionnaire.
-Si `IF EXISTS` est spécifié, il ne renvoie pas d'erreur si la table n'existe pas ou si la base de données n'existe pas.
-
-## DROP USER {#drop-user-statement}
-
-Supprime un utilisateur.
-
-### Syntaxe {#drop-user-syntax}
-
-``` sql
-DROP USER [IF EXISTS] name [,...] [ON CLUSTER cluster_name]
-```
-
-## DROP ROLE {#drop-role-statement}
-
-Supprime un rôle.
-
-Le rôle supprimé est révoqué de toutes les entités où il a été accordé.
-
-### Syntaxe {#drop-role-syntax}
-
-``` sql
-DROP ROLE [IF EXISTS] name [,...] [ON CLUSTER cluster_name]
-```
-
-## DROP ROW POLICY {#drop-row-policy-statement}
-
-Supprime une stratégie de ligne.
-
-La stratégie de ligne supprimée est révoquée de toutes les entités sur lesquelles elle a été affectée.
-
-### Syntaxe {#drop-row-policy-syntax}
-
-``` sql
-DROP [ROW] POLICY [IF EXISTS] name [,...] ON [database.]table [,...] [ON CLUSTER cluster_name]
-```
-
-## DROP QUOTA {#drop-quota-statement}
-
-Supprime un quota.
-
-Le quota supprimé est révoqué de toutes les entités où il a été affecté.
-
-### Syntaxe {#drop-quota-syntax}
-
-``` sql
-DROP QUOTA [IF EXISTS] name [,...] [ON CLUSTER cluster_name]
-```
-
-## DROP SETTINGS PROFILE {#drop-settings-profile-statement}
-
-Supprime un quota.
-
-Le quota supprimé est révoqué de toutes les entités où il a été affecté.
-
-### Syntaxe {#drop-settings-profile-syntax}
-
-``` sql
-DROP [SETTINGS] PROFILE [IF EXISTS] name [,...] [ON CLUSTER cluster_name]
-```
-
-## EXISTS {#exists-statement}
-
-``` sql
-EXISTS [TEMPORARY] [TABLE|DICTIONARY] [db.]name [INTO OUTFILE filename] [FORMAT format]
-```
-
-Renvoie un seul `UInt8`- type colonne, qui contient la valeur unique `0` si la table ou base de données n'existe pas, ou `1` si la table existe dans la base de données spécifiée.
-
-## KILL QUERY {#kill-query-statement}
-
-``` sql
-KILL QUERY [ON CLUSTER cluster]
-  WHERE <where expression to SELECT FROM system.processes query>
-  [SYNC|ASYNC|TEST]
-  [FORMAT format]
-```
-
-Tente de mettre fin de force aux requêtes en cours d'exécution.
-Les requêtes à terminer sont sélectionnées dans le système.processus en utilisant les critères définis dans le `WHERE` la clause de la `KILL` requête.
-
-Exemple:
-
-``` sql
--- Forcibly terminates all queries with the specified query_id:
-KILL QUERY WHERE query_id='2-857d-4a57-9ee0-327da5d60a90'
-
--- Synchronously terminates all queries run by 'username':
-KILL QUERY WHERE user='username' SYNC
-```
-
-Les utilisateurs en lecture seule peuvent uniquement arrêter leurs propres requêtes.
-
-Par défaut, la version asynchrone des requêtes est utilisé (`ASYNC`), qui n'attend pas la confirmation que les requêtes se sont arrêtées.
-
-La version synchrone (`SYNC`) attend que toutes les requêtes d'arrêter et affiche des informations sur chaque processus s'arrête.
-La réponse contient l' `kill_status` la colonne, qui peut prendre les valeurs suivantes:
-
-1.  ‘finished’ – The query was terminated successfully.
-2.  ‘waiting’ – Waiting for the query to end after sending it a signal to terminate.
-3.  The other values ​​explain why the query can't be stopped.
-
-Une requête de test (`TEST`) vérifie uniquement les droits de l'utilisateur et affiche une liste de requêtes à arrêter.
-
-## KILL MUTATION {#kill-mutation}
-
-``` sql
-KILL MUTATION [ON CLUSTER cluster]
-  WHERE <where expression to SELECT FROM system.mutations query>
-  [TEST]
-  [FORMAT format]
-```
-
-Essaie d'annuler et supprimer [mutation](alter.md#alter-mutations) actuellement en cours d'exécution. Les Mutations à annuler sont sélectionnées parmi [`system.mutations`](../../operations/system-tables.md#system_tables-mutations) tableau à l'aide du filtre spécifié par le `WHERE` la clause de la `KILL` requête.
-
-Une requête de test (`TEST`) vérifie uniquement les droits de l'utilisateur et affiche une liste de requêtes à arrêter.
-
-Exemple:
-
-``` sql
--- Cancel and remove all mutations of the single table:
-KILL MUTATION WHERE database = 'default' AND table = 'table'
-
--- Cancel the specific mutation:
-KILL MUTATION WHERE database = 'default' AND table = 'table' AND mutation_id = 'mutation_3.txt'
-```
-
-The query is useful when a mutation is stuck and cannot finish (e.g. if some function in the mutation query throws an exception when applied to the data contained in the table).
-
-Les modifications déjà apportées par la mutation ne sont pas annulées.
-
-## OPTIMIZE {#misc_operations-optimize}
-
-``` sql
-OPTIMIZE TABLE [db.]name [ON CLUSTER cluster] [PARTITION partition | PARTITION ID 'partition_id'] [FINAL] [DEDUPLICATE]
-```
-
-Cette requête tente d'initialiser une fusion non programmée de parties de données pour les tables avec un moteur de [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) famille.
-
-Le `OPTMIZE` la requête est également prise en charge pour [MaterializedView](../../engines/table-engines/special/materializedview.md) et la [Tampon](../../engines/table-engines/special/buffer.md) moteur. Les autres moteurs de table ne sont pas pris en charge.
-
-Lorsque `OPTIMIZE` est utilisé avec le [ReplicatedMergeTree](../../engines/table-engines/mergetree-family/replication.md) famille de moteurs de table, ClickHouse crée une tâche pour la fusion et attend l'exécution sur tous les nœuds (si le `replication_alter_partitions_sync` paramètre est activé).
-
--   Si `OPTIMIZE` n'effectue pas de fusion pour une raison quelconque, il ne notifie pas le client. Pour activer les notifications, utilisez [optimize_throw_if_noop](../../operations/settings/settings.md#setting-optimize_throw_if_noop) paramètre.
--   Si vous spécifiez un `PARTITION`, seule la partition spécifiée est optimisé. [Comment définir l'expression de la partition](alter.md#alter-how-to-specify-part-expr).
--   Si vous spécifiez `FINAL`, l'optimisation est effectuée, même lorsque toutes les données sont déjà dans une partie.
--   Si vous spécifiez `DEDUPLICATE`, alors des lignes complètement identiques seront dédupliquées (toutes les colonnes sont comparées), cela n'a de sens que pour le moteur MergeTree.
-
-!!! warning "Avertissement"
-    `OPTIMIZE` ne peut pas réparer le “Too many parts” erreur.
-
-## RENAME {#misc_operations-rename}
-
-Renomme une ou plusieurs tables.
-
-``` sql
-RENAME TABLE [db11.]name11 TO [db12.]name12, [db21.]name21 TO [db22.]name22, ... [ON CLUSTER cluster]
-```
-
-Toutes les tables sont renommées sous verrouillage global. Renommer des tables est une opération légère. Si vous avez indiqué une autre base de données après TO, la table sera déplacée vers cette base de données. Cependant, les répertoires contenant des bases de données doivent résider dans le même système de fichiers (sinon, une erreur est renvoyée).
-
-## SET {#query-set}
-
-``` sql
-SET param = value
-```
-
-Assigner `value` à l' `param` [paramètre](../../operations/settings/index.md) pour la session en cours. Vous ne pouvez pas modifier [les paramètres du serveur](../../operations/server-configuration-parameters/index.md) de cette façon.
-
-Vous pouvez également définir toutes les valeurs de certains paramètres de profil dans une seule requête.
-
-``` sql
-SET profile = 'profile-name-from-the-settings-file'
-```
-
-Pour plus d'informations, voir [Paramètre](../../operations/settings/settings.md).
-
-## SET ROLE {#set-role-statement}
-
-Active les rôles pour l'utilisateur actuel.
-
-### Syntaxe {#set-role-syntax}
-
-``` sql
-SET ROLE {DEFAULT | NONE | role [,...] | ALL | ALL EXCEPT role [,...]}
-```
-
-## SET DEFAULT ROLE {#set-default-role-statement}
-
-Définit les rôles par défaut à un utilisateur.
-
-Les rôles par défaut sont automatiquement activés lors de la connexion de l'utilisateur. Vous pouvez définir par défaut uniquement les rôles précédemment accordés. Si le rôle n'est pas accordé à un utilisateur, ClickHouse lève une exception.
-
-### Syntaxe {#set-default-role-syntax}
-
-``` sql
-SET DEFAULT ROLE {NONE | role [,...] | ALL | ALL EXCEPT role [,...]} TO {user|CURRENT_USER} [,...]
-```
-
-### Exemple {#set-default-role-examples}
-
-Définir plusieurs rôles par défaut à un utilisateur:
-
-``` sql
-SET DEFAULT ROLE role1, role2, ... TO user
-```
-
-Définissez tous les rôles accordés par défaut sur un utilisateur:
-
-``` sql
-SET DEFAULT ROLE ALL TO user
-```
-
-Purger les rôles par défaut d'un utilisateur:
-
-``` sql
-SET DEFAULT ROLE NONE TO user
-```
-
-Définissez tous les rôles accordés par défaut à l'exception de certains d'entre eux:
-
-``` sql
-SET DEFAULT ROLE ALL EXCEPT role1, role2 TO user
-```
-
-## TRUNCATE {#truncate-statement}
-
-``` sql
-TRUNCATE TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
-```
-
-Supprime toutes les données d'une table. Lorsque la clause `IF EXISTS` est omis, la requête renvoie une erreur si la table n'existe pas.
-
-Le `TRUNCATE` la requête n'est pas prise en charge pour [Vue](../../engines/table-engines/special/view.md), [Fichier](../../engines/table-engines/special/file.md), [URL](../../engines/table-engines/special/url.md) et [NULL](../../engines/table-engines/special/null.md) table des moteurs.
-
-## USE {#use}
-
-``` sql
-USE db
-```
-
-Vous permet de définir la base de données actuelle pour la session.
-La base de données actuelle est utilisée pour rechercher des tables si la base de données n'est pas explicitement définie dans la requête avec un point avant le nom de la table.
-Cette requête ne peut pas être faite lors de l'utilisation du protocole HTTP, car il n'y a pas de concept de session.

-Révoque les privilèges des utilisateurs ou rôles.
-
-## Syntaxe {#revoke-syntax}
-
-**Révocation des privilèges des utilisateurs**
-
-``` sql
-REVOKE [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} FROM {user | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user | CURRENT_USER} [,...]
-```
-
-**Révocation des rôles des utilisateurs**
-
-``` sql
-REVOKE [ON CLUSTER cluster_name] [ADMIN OPTION FOR] role [,...] FROM {user | role | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user_name | role_name | CURRENT_USER} [,...]
-```
-
-## Description {#revoke-description}
-
-Pour révoquer certains privilèges, vous pouvez utiliser un privilège de portée plus large que vous envisagez de révoquer. Par exemple, si un utilisateur a la `SELECT (x,y)` privilège, administrateur peut effectuer `REVOKE SELECT(x,y) ...`, ou `REVOKE SELECT * ...` ou même `REVOKE ALL PRIVILEGES ...` requête de révoquer ce privilège.
-
-### Révocations Partielles {#partial-revokes-dscr}
-
-Vous pouvez révoquer une partie d'un privilège. Par exemple, si un utilisateur a la `SELECT *.*` Privilège vous pouvez révoquer un privilège pour lire les données d'une table ou d'une base de données.
-
-## Exemple {#revoke-example}
-
-Subvention de l' `john` compte utilisateur avec le privilège de sélectionner parmi toutes les bases de données `accounts` un:
-
-``` sql
-GRANT SELECT ON *.* TO john;
-REVOKE SELECT ON accounts.* FROM john;
-```
-
-Subvention de l' `mira` compte utilisateur avec le privilège de sélectionner parmi toutes les colonnes `accounts.staff` tableau à l'exception de la `wage` un.
-
-``` sql
-GRANT SELECT ON accounts.staff TO mira;
-REVOKE SELECT(wage) ON accounts.staff FROM mira;
-```

-# Clause de jointure de tableau {#select-array-join-clause}
-
-C'est une opération courante pour les tables qui contiennent une colonne de tableau pour produire une nouvelle table qui a une colonne avec chaque élément de tableau individuel de cette colonne initiale, tandis que les valeurs des autres colonnes sont dupliquées. C'est le cas de fond de ce `ARRAY JOIN` la clause le fait.
-
-Son nom vient du fait qu'il peut être regardé comme l'exécution de `JOIN` avec un tableau ou une structure de données imbriquée. L'intention est similaire à la [arrayJoin](../../functions/array-join.md#functions_arrayjoin) fonction, mais la fonctionnalité de la clause est plus large.
-
-Syntaxe:
-
-``` sql
-SELECT <expr_list>
-FROM <left_subquery>
-[LEFT] ARRAY JOIN <array>
-[WHERE|PREWHERE <expr>]
-...
-```
-
-Vous ne pouvez en spécifier qu'un `ARRAY JOIN` la clause dans un `SELECT` requête.
-
-Types pris en charge de `ARRAY JOIN` sont énumérés ci-dessous:
-
--   `ARRAY JOIN` - Dans le cas de base, les tableaux vides ne sont pas inclus dans le résultat de `JOIN`.
--   `LEFT ARRAY JOIN` - Le résultat de `JOIN` contient des lignes avec des tableaux vides. La valeur d'un tableau vide est définie sur la valeur par défaut pour le type d'élément de tableau (généralement 0, chaîne vide ou NULL).
-
-## Exemples de jointure de tableau de base {#basic-array-join-examples}
-
-Les exemples ci-dessous illustrent l'utilisation de la `ARRAY JOIN` et `LEFT ARRAY JOIN` clause. Créons une table avec un [Tableau](../../../sql-reference/data-types/array.md) tapez colonne et insérez des valeurs dedans:
-
-``` sql
-CREATE TABLE arrays_test
-(
-    s String,
-    arr Array(UInt8)
-) ENGINE = Memory;
-
-INSERT INTO arrays_test
-VALUES ('Hello', [1,2]), ('World', [3,4,5]), ('Goodbye', []);
-```
-
-``` text
-┌─s───────────┬─arr─────┐
-│ Hello       │ [1,2]   │
-│ World       │ [3,4,5] │
-│ Goodbye     │ []      │
-└─────────────┴─────────┘
-```
-
-L'exemple ci-dessous utilise la `ARRAY JOIN` clause:
-
-``` sql
-SELECT s, arr
-FROM arrays_test
-ARRAY JOIN arr;
-```
-
-``` text
-┌─s─────┬─arr─┐
-│ Hello │   1 │
-│ Hello │   2 │
-│ World │   3 │
-│ World │   4 │
-│ World │   5 │
-└───────┴─────┘
-```
-
-L'exemple suivant utilise l' `LEFT ARRAY JOIN` clause:
-
-``` sql
-SELECT s, arr
-FROM arrays_test
-LEFT ARRAY JOIN arr;
-```
-
-``` text
-┌─s───────────┬─arr─┐
-│ Hello       │   1 │
-│ Hello       │   2 │
-│ World       │   3 │
-│ World       │   4 │
-│ World       │   5 │
-│ Goodbye     │   0 │
-└─────────────┴─────┘
-```
-
-## À L'Aide D'Alias {#using-aliases}
-
-Un alias peut être spécifié pour un tableau `ARRAY JOIN` clause. Dans ce cas, un élément de tableau peut être consulté par ce pseudonyme, mais le tableau lui-même est accessible par le nom d'origine. Exemple:
-
-``` sql
-SELECT s, arr, a
-FROM arrays_test
-ARRAY JOIN arr AS a;
-```
-
-``` text
-┌─s─────┬─arr─────┬─a─┐
-│ Hello │ [1,2]   │ 1 │
-│ Hello │ [1,2]   │ 2 │
-│ World │ [3,4,5] │ 3 │
-│ World │ [3,4,5] │ 4 │
-│ World │ [3,4,5] │ 5 │
-└───────┴─────────┴───┘
-```
-
-En utilisant des alias, vous pouvez effectuer `ARRAY JOIN` avec un groupe externe. Exemple:
-
-``` sql
-SELECT s, arr_external
-FROM arrays_test
-ARRAY JOIN [1, 2, 3] AS arr_external;
-```
-
-``` text
-┌─s───────────┬─arr_external─┐
-│ Hello       │            1 │
-│ Hello       │            2 │
-│ Hello       │            3 │
-│ World       │            1 │
-│ World       │            2 │
-│ World       │            3 │
-│ Goodbye     │            1 │
-│ Goodbye     │            2 │
-│ Goodbye     │            3 │
-└─────────────┴──────────────┘
-```
-
-Plusieurs tableaux peuvent être séparés par des virgules `ARRAY JOIN` clause. Dans ce cas, `JOIN` est effectuée avec eux simultanément (la somme directe, pas le produit cartésien). Notez que tous les tableaux doivent avoir la même taille. Exemple:
-
-``` sql
-SELECT s, arr, a, num, mapped
-FROM arrays_test
-ARRAY JOIN arr AS a, arrayEnumerate(arr) AS num, arrayMap(x -> x + 1, arr) AS mapped;
-```
-
-``` text
-┌─s─────┬─arr─────┬─a─┬─num─┬─mapped─┐
-│ Hello │ [1,2]   │ 1 │   1 │      2 │
-│ Hello │ [1,2]   │ 2 │   2 │      3 │
-│ World │ [3,4,5] │ 3 │   1 │      4 │
-│ World │ [3,4,5] │ 4 │   2 │      5 │
-│ World │ [3,4,5] │ 5 │   3 │      6 │
-└───────┴─────────┴───┴─────┴────────┘
-```
-
-L'exemple ci-dessous utilise la [arrayEnumerate](../../../sql-reference/functions/array-functions.md#array_functions-arrayenumerate) fonction:
-
-``` sql
-SELECT s, arr, a, num, arrayEnumerate(arr)
-FROM arrays_test
-ARRAY JOIN arr AS a, arrayEnumerate(arr) AS num;
-```
-
-``` text
-┌─s─────┬─arr─────┬─a─┬─num─┬─arrayEnumerate(arr)─┐
-│ Hello │ [1,2]   │ 1 │   1 │ [1,2]               │
-│ Hello │ [1,2]   │ 2 │   2 │ [1,2]               │
-│ World │ [3,4,5] │ 3 │   1 │ [1,2,3]             │
-│ World │ [3,4,5] │ 4 │   2 │ [1,2,3]             │
-│ World │ [3,4,5] │ 5 │   3 │ [1,2,3]             │
-└───────┴─────────┴───┴─────┴─────────────────────┘
-```
-
-## Jointure de tableau avec la Structure de données imbriquée {#array-join-with-nested-data-structure}
-
-`ARRAY JOIN` fonctionne également avec [structures de données imbriquées](../../../sql-reference/data-types/nested-data-structures/nested.md):
-
-``` sql
-CREATE TABLE nested_test
-(
-    s String,
-    nest Nested(
-    x UInt8,
-    y UInt32)
-) ENGINE = Memory;
-
-INSERT INTO nested_test
-VALUES ('Hello', [1,2], [10,20]), ('World', [3,4,5], [30,40,50]), ('Goodbye', [], []);
-```
-
-``` text
-┌─s───────┬─nest.x──┬─nest.y─────┐
-│ Hello   │ [1,2]   │ [10,20]    │
-│ World   │ [3,4,5] │ [30,40,50] │
-│ Goodbye │ []      │ []         │
-└─────────┴─────────┴────────────┘
-```
-
-``` sql
-SELECT s, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN nest;
-```
-
-``` text
-┌─s─────┬─nest.x─┬─nest.y─┐
-│ Hello │      1 │     10 │
-│ Hello │      2 │     20 │
-│ World │      3 │     30 │
-│ World │      4 │     40 │
-│ World │      5 │     50 │
-└───────┴────────┴────────┘
-```
-
-Lorsque vous spécifiez des noms de structures de données imbriquées dans `ARRAY JOIN` le sens est le même que `ARRAY JOIN` avec tous les éléments du tableau qui la compose. Des exemples sont énumérés ci-dessous:
-
-``` sql
-SELECT s, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN `nest.x`, `nest.y`;
-```
-
-``` text
-┌─s─────┬─nest.x─┬─nest.y─┐
-│ Hello │      1 │     10 │
-│ Hello │      2 │     20 │
-│ World │      3 │     30 │
-│ World │      4 │     40 │
-│ World │      5 │     50 │
-└───────┴────────┴────────┘
-```
-
-Cette variation a également du sens:
-
-``` sql
-SELECT s, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN `nest.x`;
-```
-
-``` text
-┌─s─────┬─nest.x─┬─nest.y─────┐
-│ Hello │      1 │ [10,20]    │
-│ Hello │      2 │ [10,20]    │
-│ World │      3 │ [30,40,50] │
-│ World │      4 │ [30,40,50] │
-│ World │      5 │ [30,40,50] │
-└───────┴────────┴────────────┘
-```
-
-Un alias peut être utilisé pour une structure de données imbriquée, afin de sélectionner `JOIN` le résultat ou le tableau source. Exemple:
-
-``` sql
-SELECT s, `n.x`, `n.y`, `nest.x`, `nest.y`
-FROM nested_test
-ARRAY JOIN nest AS n;
-```
-
-``` text
-┌─s─────┬─n.x─┬─n.y─┬─nest.x──┬─nest.y─────┐
-│ Hello │   1 │  10 │ [1,2]   │ [10,20]    │
-│ Hello │   2 │  20 │ [1,2]   │ [10,20]    │
-│ World │   3 │  30 │ [3,4,5] │ [30,40,50] │
-│ World │   4 │  40 │ [3,4,5] │ [30,40,50] │
-│ World │   5 │  50 │ [3,4,5] │ [30,40,50] │
-└───────┴─────┴─────┴─────────┴────────────┘
-```
-
-Exemple d'utilisation de l' [arrayEnumerate](../../../sql-reference/functions/array-functions.md#array_functions-arrayenumerate) fonction:
-
-``` sql
-SELECT s, `n.x`, `n.y`, `nest.x`, `nest.y`, num
-FROM nested_test
-ARRAY JOIN nest AS n, arrayEnumerate(`nest.x`) AS num;
-```
-
-``` text
-┌─s─────┬─n.x─┬─n.y─┬─nest.x──┬─nest.y─────┬─num─┐

-## Détails De Mise En Œuvre {#implementation-details}
-
-L'ordre d'exécution de la requête est optimisé lors de l'exécution `ARRAY JOIN`. Bien `ARRAY JOIN` doit toujours être spécifié avant l' [WHERE](where.md)/[PREWHERE](prewhere.md) dans une requête, techniquement, ils peuvent être exécutés dans n'importe quel ordre, sauf résultat de `ARRAY JOIN` est utilisé pour le filtrage. L'ordre de traitement est contrôlée par l'optimiseur de requête.

-# La Clause DISTINCT {#select-distinct}
-
-Si `SELECT DISTINCT` est spécifié, seules les lignes uniques restera un résultat de requête. Ainsi, une seule ligne restera hors de tous les ensembles de lignes entièrement correspondantes dans le résultat.
-
-## Le Traitement Null {#null-processing}
-
-`DISTINCT` fonctionne avec [NULL](../../syntax.md#null-literal) comme si `NULL` ont une valeur spécifique, et `NULL==NULL`. En d'autres termes, dans le `DISTINCT` résultats, différentes combinaisons avec `NULL` une fois seulement. Elle diffère de `NULL` traitement dans la plupart des autres contextes.
-
-## Alternative {#alternatives}
-
-Il est possible d'obtenir le même résultat en appliquant [GROUP BY](group-by.md) sur le même ensemble de valeurs, comme spécifié comme `SELECT` clause, sans utiliser de fonctions d'agrégation. Mais il y a peu de différences de `GROUP BY` approche:
-
--   `DISTINCT` peut être utilisé avec d' `GROUP BY`.
--   Lorsque [ORDER BY](order-by.md) est omis et [LIMIT](limit.md) est définie, la requête s'arrête immédiatement après le nombre de lignes différentes, a été lu.
--   Les blocs de données sont produits au fur et à mesure qu'ils sont traités, sans attendre que la requête entière se termine.
-
-## Limitation {#limitations}
-
-`DISTINCT` n'est pas pris en charge si `SELECT` a au moins une colonne de tableau.
-
-## Exemple {#examples}
-
-Clickhouse prend en charge l'utilisation du `DISTINCT` et `ORDER BY` clauses pour différentes colonnes dans une requête. Le `DISTINCT` la clause est exécutée avant la `ORDER BY` clause.
-
-Exemple de table:
-
-``` text
-┌─a─┬─b─┐
-│ 2 │ 1 │
-│ 1 │ 2 │
-│ 3 │ 3 │
-│ 2 │ 4 │
-└───┴───┘
-```
-
-Lors de la sélection de données avec le `SELECT DISTINCT a FROM t1 ORDER BY b ASC` requête, nous obtenons le résultat suivant:
-
-``` text
-┌─a─┐
-│ 2 │
-│ 1 │
-│ 3 │
-└───┘
-```
-
-Si nous changeons la direction de tri `SELECT DISTINCT a FROM t1 ORDER BY b DESC`, nous obtenons le résultat suivant:
-
-``` text
-┌─a─┐
-│ 3 │
-│ 1 │
-│ 2 │
-└───┘
-```
-
-Rangée `2, 4` a été coupé avant de les trier.
-

-# FORMAT de la Clause {#format-clause}
-
-Clickhouse prend en charge une large gamme de [formats de sérialisation](../../../interfaces/formats.md) qui peut être utilisé sur les résultats de la requête entre autres choses. Il existe plusieurs façons de choisir un format pour `SELECT` de sortie, l'un d'eux est de spécifier `FORMAT format` à la fin de la requête pour obtenir les données résultantes dans tout format spécifique.
-
-Un format spécifique peut être utilisé pour des raisons de commodité, d'intégration avec d'autres systèmes ou d'amélioration des performances.
-
-## Format Par Défaut {#default-format}
-
-Si l' `FORMAT` la clause est omise, le format par défaut est utilisé, ce qui dépend à la fois des paramètres et de l'interface utilisée pour accéder au serveur ClickHouse. Pour l' [Interface HTTP](../../../interfaces/http.md) et la [client de ligne de commande](../../../interfaces/cli.md) en mode batch, le format par défaut est `TabSeparated`. Pour le client de ligne de commande en mode interactif, le format par défaut est `PrettyCompact` (il produit des tables compactes lisibles par l'homme).
-
-## Détails De Mise En Œuvre {#implementation-details}
-
-Lors de l'utilisation du client de ligne de commande, les données sont toujours transmises sur le réseau dans un format efficace interne (`Native`). Le client interprète indépendamment le `FORMAT` clause de la requête et formate les données elles-mêmes (soulageant ainsi le réseau et le serveur de la charge supplémentaire).

-# De la Clause {#select-from}
-
-Le `FROM` clause spécifie la source à partir de laquelle lire les données:
-
--   [Table](../../../engines/table-engines/index.md)
--   [Sous-requête](index.md) {##TODO: meilleur lien ##}
--   [Fonction de Table](../../table-functions/index.md#table-functions)
-
-[JOIN](join.md) et [ARRAY JOIN](array-join.md) les clauses peuvent également être utilisées pour étendre la fonctionnalité de la `FROM` clause.
-
-Subquery est un autre `SELECT` requête qui peut être spécifié entre parenthèses à l'intérieur `FROM` clause.
-
-`FROM` la clause peut contenir plusieurs sources de données, séparées par des virgules, ce qui équivaut à effectuer [CROSS JOIN](join.md) sur eux.
-
-## Modificateur FINAL {#select-from-final}
-
-Lorsque `FINAL` est spécifié, ClickHouse fusionne complètement les données avant de renvoyer le résultat et effectue ainsi toutes les transformations de données qui se produisent lors des fusions pour le moteur de table donné.
-
-Il est applicable lors de la sélection de données à partir de tables qui utilisent [MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md)-la famille de moteurs (à l'exception de `GraphiteMergeTree`). Également pris en charge pour:
-
--   [Répliqué](../../../engines/table-engines/mergetree-family/replication.md) les versions de `MergeTree` moteur.
--   [Vue](../../../engines/table-engines/special/view.md), [Tampon](../../../engines/table-engines/special/buffer.md), [Distribué](../../../engines/table-engines/special/distributed.md), et [MaterializedView](../../../engines/table-engines/special/materializedview.md) moteurs qui fonctionnent sur d'autres moteurs, à condition qu'ils aient été créés sur `MergeTree`-tables de moteur.
-
-### Inconvénient {#drawbacks}
-
-Requêtes qui utilisent `FINAL` sont exécutés pas aussi vite que les requêtes similaires qui ne le font pas, car:
-
--   La requête est exécutée dans un seul thread et les données sont fusionnées lors de l'exécution de la requête.
--   Les requêtes avec `FINAL` lire les colonnes de clé primaire en plus des colonnes spécifiées dans la requête.
-
-**Dans la plupart des cas, évitez d'utiliser `FINAL`.** L'approche commune consiste à utiliser différentes requêtes qui supposent les processus d'arrière-plan du `MergeTree` le moteur n'est pas encore arrivé et y faire face en appliquant l'agrégation (par exemple, pour éliminer les doublons). {##TODO: exemples ##}
-
-## Détails De Mise En Œuvre {#implementation-details}
-
-Si l' `FROM` la clause est omise, les données seront lues à partir `system.one` table.
-Le `system.one` table contient exactement une ligne (cette table remplit le même but que la table double trouvée dans d'autres SGBD).
-
-Pour exécuter une requête, toutes les colonnes mentionnées dans la requête sont extraites de la table appropriée. Toutes les colonnes non nécessaires pour la requête externe sont rejetées des sous-requêtes.
-Si une requête ne répertorie aucune colonne (par exemple, `SELECT count() FROM t`), une colonne est extraite de la table de toute façon (la plus petite est préférée), afin de calculer le nombre de lignes.

-# Clause GROUP BY {#select-group-by-clause}
-
-`GROUP BY` la clause change le `SELECT` requête dans un mode d'agrégation, qui fonctionne comme suit:
-
--   `GROUP BY` clause contient une liste des expressions (ou une seule expression, qui est considéré comme la liste de longueur). Cette liste agit comme un “grouping key”, tandis que chaque expression individuelle sera appelée “key expressions”.
--   Toutes les expressions dans le [SELECT](index.md), [HAVING](having.md), et [ORDER BY](order-by.md) clause **devoir** être calculé sur la base d'expressions clés **ou** sur [les fonctions d'agrégation](../../../sql-reference/aggregate-functions/index.md) sur les expressions non-clés (y compris les colonnes simples). En d'autres termes, chaque colonne sélectionnée dans la table doit être utilisée soit dans une expression de clé, soit dans une fonction d'agrégat, mais pas les deux.
--   Résultat de l'agrégation de `SELECT` la requête contiendra autant de lignes qu'il y avait des valeurs uniques de “grouping key” dans la table source. Habituellement, cela réduit considérablement le nombre de lignes, souvent par ordre de grandeur, mais pas nécessairement: le nombre de lignes reste le même si tous “grouping key” les valeurs sont distinctes.
-
-!!! note "Note"
-    Il existe un moyen supplémentaire d'exécuter l'agrégation sur une table. Si une requête ne contient que des colonnes de table à l'intérieur des fonctions `GROUP BY clause` peut être omis, et l'agrégation par un ensemble vide de touches est supposé. Ces interrogations renvoient toujours exactement une ligne.
-
-## Le Traitement NULL {#null-processing}
-
-Pour le regroupement, ClickHouse interprète [NULL](../../syntax.md#null-literal) comme une valeur, et `NULL==NULL`. Elle diffère de `NULL` traitement dans la plupart des autres contextes.
-
-Voici un exemple pour montrer ce que cela signifie.
-
-Supposons que vous avez cette table:

-
-Vous pouvez voir que `GROUP BY` pour `y = NULL` résumer `x` comme si `NULL` a cette valeur.
-
-Si vous passez plusieurs clés `GROUP BY` le résultat vous donnera toutes les combinaisons de la sélection, comme si `NULL` ont une valeur spécifique.
-
-## Avec modificateur de totaux {#with-totals-modifier}
-
-Si l' `WITH TOTALS` modificateur est spécifié, une autre ligne sera calculée. Cette ligne aura des colonnes clés contenant des valeurs par défaut (zéros ou lignes vides), et des colonnes de fonctions d'agrégat avec les valeurs calculées sur toutes les lignes (le “total” valeur).
-
-Cette ligne supplémentaire est uniquement produite en `JSON*`, `TabSeparated*`, et `Pretty*` formats, séparément des autres lignes:
-
--   Dans `JSON*` formats, cette ligne est sortie en tant que distinct ‘totals’ champ.
--   Dans `TabSeparated*` formats, la ligne vient après le résultat principal, précédé par une ligne vide (après les autres données).
--   Dans `Pretty*` formats, la ligne est sortie comme une table séparée après le résultat principal.
--   Dans les autres formats, il n'est pas disponible.
-
-`WITH TOTALS` peut être exécuté de différentes manières lorsqu'il est présent. Le comportement dépend de l' ‘totals_mode’ paramètre.
-
-### Configuration Du Traitement Des Totaux {#configuring-totals-processing}
-
-Par défaut, `totals_mode = 'before_having'`. Dans ce cas, ‘totals’ est calculé sur toutes les lignes, y compris celles qui ne passent pas par `max_rows_to_group_by`.
-
-Les autres alternatives incluent uniquement les lignes qui passent à travers avoir dans ‘totals’, et se comporter différemment avec le réglage `max_rows_to_group_by` et `group_by_overflow_mode = 'any'`.
-
-`after_having_exclusive` – Don't include rows that didn't pass through `max_rows_to_group_by`. En d'autres termes, ‘totals’ aura moins ou le même nombre de lignes que si `max_rows_to_group_by` ont été omis.
-
-`after_having_inclusive` – Include all the rows that didn't pass through ‘max_rows_to_group_by’ dans ‘totals’. En d'autres termes, ‘totals’ aura plus ou le même nombre de lignes que si `max_rows_to_group_by` ont été omis.
-
-`after_having_auto` – Count the number of rows that passed through HAVING. If it is more than a certain amount (by default, 50%), include all the rows that didn't pass through ‘max_rows_to_group_by’ dans ‘totals’. Sinon, ne pas les inclure.
-
-`totals_auto_threshold` – By default, 0.5. The coefficient for `after_having_auto`.
-
-Si `max_rows_to_group_by` et `group_by_overflow_mode = 'any'` ne sont pas utilisés, toutes les variations de `after_having` sont les mêmes, et vous pouvez utiliser l'un d'eux (par exemple, `after_having_auto`).
-
-Vous pouvez utiliser avec les totaux dans les sous-requêtes, y compris les sous-requêtes dans la clause JOIN (dans ce cas, les valeurs totales respectives sont combinées).
-
-## Exemple {#examples}
-
-Exemple:
-
-``` sql
-SELECT
-    count(),
-    median(FetchTiming > 60 ? 60 : FetchTiming),
-    count() - sum(Refresh)
-FROM hits
-```
-
-Cependant, contrairement au SQL standard, si la table n'a pas de lignes (soit il n'y en a pas du tout, soit il n'y en a pas après avoir utilisé WHERE to filter), un résultat vide est renvoyé, et non le résultat d'une des lignes contenant les valeurs initiales des fonctions d'agrégat.
-
-Contrairement à MySQL (et conforme à SQL standard), vous ne pouvez pas obtenir une valeur d'une colonne qui n'est pas dans une fonction clé ou agrégée (sauf les expressions constantes). Pour contourner ce problème, vous pouvez utiliser le ‘any’ fonction d'agrégation (récupère la première valeur rencontrée) ou ‘min/max’.
-
-Exemple:
-
-``` sql
-SELECT
-    domainWithoutWWW(URL) AS domain,
-    count(),
-    any(Title) AS title -- getting the first occurred page header for each domain.
-FROM hits
-GROUP BY domain
-```
-
-Pour chaque valeur de clé différente rencontrée, GROUP BY calcule un ensemble de valeurs de fonction d'agrégation.
-
-GROUP BY n'est pas pris en charge pour les colonnes de tableau.
-
-Une constante ne peut pas être spécifiée comme arguments pour les fonctions d'agrégation. Exemple: somme(1). Au lieu de cela, vous pouvez vous débarrasser de la constante. Exemple: `count()`.
-
-## Détails De Mise En Œuvre {#implementation-details}
-
-L'agrégation est l'une des caractéristiques les plus importantes d'un SGBD orienté colonne, et donc son implémentation est l'une des parties les plus optimisées de ClickHouse. Par défaut, l'agrégation se fait en mémoire à l'aide d'une table de hachage. Il a plus de 40 spécialisations qui sont choisies automatiquement en fonction de “grouping key” types de données.
-
-### Groupe par dans la mémoire externe {#select-group-by-in-external-memory}
-
-Vous pouvez activer le dumping des données temporaires sur le disque pour limiter l'utilisation de la mémoire pendant `GROUP BY`.
-Le [max_bytes_before_external_group_by](../../../operations/settings/settings.md#settings-max_bytes_before_external_group_by) réglage détermine le seuil de consommation de RAM pour le dumping `GROUP BY` données temporaires dans le système de fichiers. Si elle est définie sur 0 (valeur par défaut), elle est désactivée.
-
-Lors de l'utilisation de `max_bytes_before_external_group_by`, nous vous recommandons de définir `max_memory_usage` environ deux fois plus élevé. Ceci est nécessaire car il y a deux étapes à l'agrégation: la lecture des données et la formation des données intermédiaires (1) et la fusion des données intermédiaires (2). Le Dumping des données dans le système de fichiers ne peut se produire qu'au cours de l'étape 1. Si les données temporaires n'ont pas été vidées, l'étape 2 peut nécessiter jusqu'à la même quantité de mémoire qu'à l'étape 1.
-
-Par exemple, si [max_memory_usage](../../../operations/settings/settings.md#settings_max_memory_usage) a été défini sur 10000000000 et que vous souhaitez utiliser l'agrégation externe, il est logique de définir `max_bytes_before_external_group_by` à 10000000000, et `max_memory_usage` à 20000000000. Lorsque l'agrégation externe est déclenchée (s'il y a eu au moins un vidage de données temporaires), la consommation maximale de RAM n'est que légèrement supérieure à `max_bytes_before_external_group_by`.
-
-Avec le traitement des requêtes distribuées, l'agrégation externe est effectuée sur des serveurs distants. Pour que le serveur demandeur n'utilise qu'une petite quantité de RAM, définissez `distributed_aggregation_memory_efficient` 1.
-
-Lors de la fusion de données vidées sur le disque, ainsi que lors de la fusion des résultats de serveurs distants lorsque `distributed_aggregation_memory_efficient` paramètre est activé, consomme jusqu'à `1/256 * the_number_of_threads` à partir de la quantité totale de mémoire RAM.
-
-Lorsque l'agrégation externe est activée, s'il y a moins de `max_bytes_before_external_group_by` of data (i.e. data was not flushed), the query runs just as fast as without external aggregation. If any temporary data was flushed, the run time will be several times longer (approximately three times).
-
-Si vous avez un [ORDER BY](order-by.md) avec un [LIMIT](limit.md) après `GROUP BY` puis la quantité de RAM dépend de la quantité de données dans `LIMIT`, pas dans l'ensemble de la table. Mais si l' `ORDER BY` n'a pas `LIMIT`, n'oubliez pas d'activer externe de tri (`max_bytes_before_external_sort`).

-# Clause HAVING {#having-clause}
-
-Permet de filtrer les résultats d'agrégation produits par [GROUP BY](group-by.md). Il est similaire à la [WHERE](where.md) la clause, mais la différence est que `WHERE` est effectuée avant l'agrégation, tandis que `HAVING` est effectué d'après elle.
-
-Il est possible de référencer les résultats d'agrégation à partir de `SELECT` la clause dans `HAVING` clause par leur alias. Alternativement, `HAVING` clause peut filtrer sur les résultats d'agrégats supplémentaires qui ne sont pas retournés dans les résultats de la requête.
-
-## Limitation {#limitations}
-
-`HAVING` ne peut pas être utilisé si le regroupement n'est pas effectuée. Utiliser `WHERE` plutôt.

-
-## Clause SELECT {#select-clause}
-
-[Expression](../../syntax.md#syntax-expressions) spécifié dans le `SELECT` clause sont calculés après toutes les opérations dans les clauses décrites ci-dessus sont terminés. Ces expressions fonctionnent comme si elles s'appliquaient à des lignes séparées dans le résultat. Si les expressions dans le `SELECT` la clause contient des fonctions d'agrégation, puis clickhouse traite les fonctions d'agrégation et les expressions utilisées [GROUP BY](group-by.md) agrégation.
-
-Si vous souhaitez inclure toutes les colonnes dans le résultat, utilisez l'astérisque (`*`) symbole. Exemple, `SELECT * FROM ...`.
-
-Pour correspondre à certaines colonnes dans le résultat avec un [re2](https://en.wikipedia.org/wiki/RE2_(software)) expression régulière, vous pouvez utiliser le `COLUMNS` expression.
-
-``` sql
-COLUMNS('regexp')
-```
-
-Par exemple, considérez le tableau:
-
-``` sql
-CREATE TABLE default.col_names (aa Int8, ab Int8, bc Int8) ENGINE = TinyLog
-```
-
-La requête suivante sélectionne les données de toutes les colonnes contenant les `a` symbole dans leur nom.
-
-``` sql
-SELECT COLUMNS('a') FROM col_names
-```
-
-``` text
-┌─aa─┬─ab─┐
-│  1 │  1 │
-└────┴────┘
-```
-
-Les colonnes sélectionnées sont retournés pas dans l'ordre alphabétique.
-
-Vous pouvez utiliser plusieurs `COLUMNS` expressions dans une requête et leur appliquer des fonctions.
-
-Exemple:
-
-``` sql
-SELECT COLUMNS('a'), COLUMNS('c'), toTypeName(COLUMNS('c')) FROM col_names
-```
-
-``` text
-┌─aa─┬─ab─┬─bc─┬─toTypeName(bc)─┐
-│  1 │  1 │  1 │ Int8           │
-└────┴────┴────┴────────────────┘
-```
-
-Chaque colonne renvoyée par le `COLUMNS` expression est passée à la fonction en tant qu'argument séparé. Vous pouvez également passer d'autres arguments à la fonction si elle les supporte. Soyez prudent lorsque vous utilisez des fonctions. Si une fonction ne prend pas en charge le nombre d'arguments que vous lui avez transmis, ClickHouse lève une exception.
-
-Exemple:
-
-``` sql
-SELECT COLUMNS('a') + COLUMNS('c') FROM col_names
-```
-
-``` text
-Received exception from server (version 19.14.1):
-Code: 42. DB::Exception: Received from localhost:9000. DB::Exception: Number of arguments for function plus doesn't match: passed 3, should be 2.
-```
-
-Dans cet exemple, `COLUMNS('a')` retourne deux colonnes: `aa` et `ab`. `COLUMNS('c')` renvoie la `bc` colonne. Le `+` l'opérateur ne peut pas s'appliquer à 3 arguments, donc ClickHouse lève une exception avec le message pertinent.
-
-Colonnes qui correspondent à la `COLUMNS` l'expression peut avoir différents types de données. Si `COLUMNS` ne correspond à aucune colonne et est la seule expression dans `SELECT`, ClickHouse lance une exception.
-
-### Astérisque {#asterisk}
-
-Vous pouvez mettre un astérisque dans quelque partie de la requête au lieu d'une expression. Lorsque la requête est analysée, l'astérisque est étendu à une liste de toutes les colonnes `MATERIALIZED` et `ALIAS` colonne). Il n'y a que quelques cas où l'utilisation d'un astérisque est justifiée:
-
--   Lors de la création d'un vidage de table.
--   Pour les tables contenant seulement quelques colonnes, comme les tables système.
--   Pour obtenir des informations sur ce que sont les colonnes dans une table. Dans ce cas, la valeur `LIMIT 1`. Mais il est préférable d'utiliser la `DESC TABLE` requête.
--   Quand il y a une forte filtration sur un petit nombre de colonnes en utilisant `PREWHERE`.
--   Dans les sous-requêtes (puisque les colonnes qui ne sont pas nécessaires pour la requête externe sont exclues des sous-requêtes).
-
-Dans tous les autres cas, nous ne recommandons pas d'utiliser l'astérisque, car il ne vous donne que les inconvénients d'un SGBD colonnaire au lieu des avantages. En d'autres termes, l'utilisation de l'astérisque n'est pas recommandée.
-
-### Les Valeurs Extrêmes {#extreme-values}
-
-En plus des résultats, vous pouvez également obtenir des valeurs minimales et maximales pour les colonnes de résultats. Pour ce faire, définissez la **extrême** réglage sur 1. Les Minimums et les maximums sont calculés pour les types numériques, les dates et les dates avec des heures. Pour les autres colonnes, les valeurs par défaut sont sorties.
-
-An extra two rows are calculated – the minimums and maximums, respectively. These extra two rows are output in `JSON*`, `TabSeparated*`, et `Pretty*` [format](../../../interfaces/formats.md), séparés des autres lignes. Ils ne sont pas Produits pour d'autres formats.
-
-Dans `JSON*` formats, les valeurs extrêmes sont sorties dans un ‘extremes’ champ. Dans `TabSeparated*` formats, la ligne vient après le résultat principal, et après ‘totals’ si elle est présente. Elle est précédée par une ligne vide (après les autres données). Dans `Pretty*` formats, la ligne est sortie comme une table séparée après le résultat principal, et après `totals` si elle est présente.
-
-Les valeurs extrêmes sont calculées pour les lignes avant `LIMIT` mais après `LIMIT BY`. Cependant, lors de l'utilisation de `LIMIT offset, size`, les lignes avant de les `offset` sont inclus dans `extremes`. Dans les requêtes de flux, le résultat peut également inclure un petit nombre de lignes qui ont traversé `LIMIT`.
-
-### Note {#notes}
-
-Vous pouvez utiliser des synonymes (`AS` alias) dans n'importe quelle partie d'une requête.
-
-Le `GROUP BY` et `ORDER BY` les clauses ne supportent pas les arguments positionnels. Cela contredit MySQL, mais est conforme à SQL standard. Exemple, `GROUP BY 1, 2` will be interpreted as grouping by constants (i.e. aggregation of all rows into one).
-
-## Détails De Mise En Œuvre {#implementation-details}
-
-Si la requête omet le `DISTINCT`, `GROUP BY` et `ORDER BY` les clauses et les `IN` et `JOIN` sous-requêtes, la requête sera complètement traitée en flux, en utilisant O (1) quantité de RAM. Sinon, la requête peut consommer beaucoup de RAM si les restrictions appropriées ne sont pas spécifiées:
-
--   `max_memory_usage`
--   `max_rows_to_group_by`
--   `max_rows_to_sort`
--   `max_rows_in_distinct`
--   `max_bytes_in_distinct`
--   `max_rows_in_set`
--   `max_bytes_in_set`
--   `max_rows_in_join`
--   `max_bytes_in_join`
--   `max_bytes_before_external_sort`
--   `max_bytes_before_external_group_by`
-
-Pour plus d'informations, consultez la section “Settings”. Il est possible d'utiliser le tri externe (sauvegarde des tables temporaires sur un disque) et l'agrégation externe.

-# Clause de JOINTURE {#select-join}
-
-Join produit une nouvelle table en combinant des colonnes d'une ou plusieurs tables en utilisant des valeurs communes à chacune. C'est une opération courante dans les bases de données avec support SQL, ce qui correspond à [l'algèbre relationnelle](https://en.wikipedia.org/wiki/Relational_algebra#Joins_and_join-like_operators) rejoindre. Le cas particulier d'une jointure de table est souvent appelé “self-join”.
-
-Syntaxe:
-
-``` sql
-SELECT <expr_list>
-FROM <left_table>
-[GLOBAL] [INNER|LEFT|RIGHT|FULL|CROSS] [OUTER|SEMI|ANTI|ANY|ASOF] JOIN <right_table>
-(ON <expr_list>)|(USING <column_list>) ...
-```
-
-Les Expressions de `ON` clause et colonnes de `USING` clause sont appelés “join keys”. Sauf indication contraire, joindre un produit [Produit cartésien](https://en.wikipedia.org/wiki/Cartesian_product) des lignes, avec correspondance “join keys”, ce qui pourrait produire des résultats avec beaucoup plus de lignes que les tables source.
-
-## Types de jointure pris en charge {#select-join-types}
-
-Tous les standard [SQL JOIN](https://en.wikipedia.org/wiki/Join_(SQL)) les types sont pris en charge:
-
--   `INNER JOIN`, seules les lignes correspondantes sont retournés.
--   `LEFT OUTER JOIN`, les lignes non correspondantes de la table de gauche sont retournées en plus des lignes correspondantes.
--   `RIGHT OUTER JOIN`, les lignes non correspondantes de la table de gauche sont retournées en plus des lignes correspondantes.
--   `FULL OUTER JOIN`, les lignes non correspondantes des deux tables sont renvoyées en plus des lignes correspondantes.
--   `CROSS JOIN`, produit le produit cartésien des tables entières, “join keys” être **pas** défini.
-
-`JOIN` sans type spécifié implique `INNER`. Mot `OUTER` peut les oublier. Syntaxe Alternative pour `CROSS JOIN` spécifie plusieurs tables dans [De la clause](from.md) séparés par des virgules.
-
-Autres types de jointure disponibles dans ClickHouse:
-
--   `LEFT SEMI JOIN` et `RIGHT SEMI JOIN` une liste blanche sur “join keys”, sans produire un produit cartésien.
--   `LEFT ANTI JOIN` et `RIGHT ANTI JOIN` une liste noire sur “join keys”, sans produire un produit cartésien.
--   `LEFT ANY JOIN`, `RIGHT ANY JOIN` et `INNER ANY JOIN`, partially (for opposite side of `LEFT` and `RIGHT`) or completely (for `INNER` and `FULL`) disables the cartesian product for standard `JOIN` types.
--   `ASOF JOIN` et `LEFT ASOF JOIN`, joining sequences with a non-exact match. `ASOF JOIN` usage is described below.
-
-## Setting {#join-settings}
-
-!!! note "Note"
-    La valeur de rigueur par défaut peut être remplacée à l'aide [join_default_strictness](../../../operations/settings/settings.md#settings-join_default_strictness) paramètre.
-
-### ASOF joindre L'utilisation {#asof-join-usage}
-
-`ASOF JOIN` est utile lorsque vous devez joindre des enregistrements qui n'ont pas de correspondance exacte.
-
-Tables pour `ASOF JOIN` doit avoir une colonne de séquence ordonnée. Cette colonne ne peut pas être seule dans une table et doit être l'un des types de données: `UInt32`, `UInt64`, `Float32`, `Float64`, `Date`, et `DateTime`.
-
-Syntaxe `ASOF JOIN ... ON`:
-
-``` sql
-SELECT expressions_list
-FROM table_1
-ASOF LEFT JOIN table_2
-ON equi_cond AND closest_match_cond
-```
-
-Vous pouvez utiliser n'importe quel nombre de conditions d'égalité et exactement une condition de correspondance la plus proche. Exemple, `SELECT count() FROM table_1 ASOF LEFT JOIN table_2 ON table_1.a == table_2.b AND table_2.t <= table_1.t`.
-
-Conditions prises en charge pour la correspondance la plus proche: `>`, `>=`, `<`, `<=`.
-
-Syntaxe `ASOF JOIN ... USING`:
-
-``` sql
-SELECT expressions_list
-FROM table_1
-ASOF JOIN table_2
-USING (equi_column1, ... equi_columnN, asof_column)
-```
-
-`ASOF JOIN` utiliser `equi_columnX` pour rejoindre sur l'égalité et `asof_column` pour rejoindre le match le plus proche avec le `table_1.asof_column >= table_2.asof_column` condition. Le `asof_column` colonne toujours la dernière dans le `USING` clause.
-
-Par exemple, considérez les tableaux suivants:
-
-         table_1                           table_2
-      event   | ev_time | user_id       event   | ev_time | user_id
-    ----------|---------|----------   ----------|---------|----------
-                  ...                               ...
-    event_1_1 |  12:00  |  42         event_2_1 |  11:59  |   42
-                  ...                 event_2_2 |  12:30  |   42
-    event_1_2 |  13:00  |  42         event_2_3 |  13:00  |   42
-                  ...                               ...
-
-`ASOF JOIN` peut prendre la date d'un événement utilisateur de `table_1` et trouver un événement dans `table_2` où le timestamp est plus proche de l'horodatage de l'événement à partir de `table_1` correspondant à la condition de correspondance la plus proche. Les valeurs d'horodatage égales sont les plus proches si elles sont disponibles. Ici, l' `user_id` la colonne peut être utilisée pour joindre sur l'égalité et le `ev_time` la colonne peut être utilisée pour se joindre à la correspondance la plus proche. Dans notre exemple, `event_1_1` peut être jointe à `event_2_1` et `event_1_2` peut être jointe à `event_2_3`, mais `event_2_2` ne peut pas être rejoint.
-
-!!! note "Note"
-    `ASOF` jointure est **pas** pris en charge dans le [Rejoindre](../../../engines/table-engines/special/join.md) tableau moteur.
-
-## Jointure Distribuée {#global-join}
-
-Il existe deux façons d'exécuter join impliquant des tables distribuées:
-
--   Lors de l'utilisation normale `JOIN` la requête est envoyée aux serveurs distants. Les sous-requêtes sont exécutées sur chacune d'elles afin de créer la bonne table, et la jointure est effectuée avec cette table. En d'autres termes, la table de droite est formée sur chaque serveur séparément.
--   Lors de l'utilisation de `GLOBAL ... JOIN`, d'abord le serveur demandeur exécute une sous-requête pour calculer la bonne table. Cette table temporaire est transmise à chaque serveur distant, et les requêtes sont exécutées sur eux en utilisant les données temporaires qui ont été transmises.
-
-Soyez prudent lorsque vous utilisez `GLOBAL`. Pour plus d'informations, voir le [Sous-requêtes distribuées](../../operators/in.md#select-distributed-subqueries) section.
-
-## Recommandations D'Utilisation {#usage-recommendations}
-
-### Traitement des cellules vides ou nulles {#processing-of-empty-or-null-cells}
-
-Lors de la jonction de tables, les cellules vides peuvent apparaître. Paramètre [join_use_nulls](../../../operations/settings/settings.md#join_use_nulls) définir comment clickhouse remplit ces cellules.
-
-Si l' `JOIN` les touches sont [Nullable](../../data-types/nullable.md) champs, les lignes où au moins une des clés a la valeur [NULL](../../../sql-reference/syntax.md#null-literal) ne sont pas jointes.
-
-### Syntaxe {#syntax}
-
-Les colonnes spécifiées dans `USING` doit avoir les mêmes noms dans les deux sous-requêtes, et les autres colonnes doivent être nommées différemment. Vous pouvez utiliser des alias pour les noms des colonnes dans les sous-requêtes.
-
-Le `USING` clause spécifie une ou plusieurs colonnes de jointure, qui établit l'égalité de ces colonnes. La liste des colonnes est définie sans crochets. Les conditions de jointure plus complexes ne sont pas prises en charge.
-
-### Limitations De Syntaxe {#syntax-limitations}
-
-Pour plusieurs `JOIN` clauses dans un seul `SELECT` requête:
-
--   Prendre toutes les colonnes via `*` n'est disponible que si les tables sont jointes, pas les sous-requêtes.
--   Le `PREWHERE` la clause n'est pas disponible.
-
-Pour `ON`, `WHERE`, et `GROUP BY` clause:
-
--   Les expressions arbitraires ne peuvent pas être utilisées dans `ON`, `WHERE`, et `GROUP BY` mais vous pouvez définir une expression dans un `SELECT` clause et ensuite l'utiliser dans ces clauses via un alias.
-
-### Performance {#performance}
-
-Lors de l'exécution d'un `JOIN`, il n'y a pas d'optimisation de la commande d'exécution par rapport aux autres stades de la requête. La jointure (une recherche dans la table de droite) est exécutée avant de filtrer `WHERE` et avant l'agrégation.
-
-Chaque fois qu'une requête est exécutée avec la même `JOIN`, la sous-requête est exécutée à nouveau car le résultat n'est pas mis en cache. Pour éviter cela, utilisez la spéciale [Rejoindre](../../../engines/table-engines/special/join.md) table engine, qui est un tableau préparé pour l'assemblage qui est toujours en RAM.
-
-Dans certains cas, il est plus efficace d'utiliser [IN](../../operators/in.md) plutôt `JOIN`.
-
-Si vous avez besoin d'un `JOIN` pour se joindre à des tables de dimension (ce sont des tables relativement petites qui contiennent des propriétés de dimension, telles que des noms pour des campagnes publicitaires), un `JOIN` peut-être pas très pratique en raison du fait que la bonne table est ré-accédée pour chaque requête. Pour de tels cas, il y a un “external dictionaries” la fonctionnalité que vous devez utiliser à la place de `JOIN`. Pour plus d'informations, voir le [Dictionnaires externes](../../dictionaries/external-dictionaries/external-dicts.md) section.
-
-### Limitations De Mémoire {#memory-limitations}
-
-Par défaut, ClickHouse utilise [jointure de hachage](https://en.wikipedia.org/wiki/Hash_join) algorithme. ClickHouse prend le `<right_table>` et crée une table de hachage pour cela dans la RAM. Après un certain seuil de consommation de mémoire, ClickHouse revient à fusionner l'algorithme de jointure.
-
-Si vous devez restreindre la consommation de mémoire de l'opération join utilisez les paramètres suivants:
-
--   [max_rows_in_join](../../../operations/settings/query-complexity.md#settings-max_rows_in_join) — Limits number of rows in the hash table.
--   [max_bytes_in_join](../../../operations/settings/query-complexity.md#settings-max_bytes_in_join) — Limits size of the hash table.
-
-Lorsque l'une de ces limites est atteinte, ClickHouse agit comme [join_overflow_mode](../../../operations/settings/query-complexity.md#settings-join_overflow_mode) réglage des instructions.

-# Limite par Clause {#limit-by-clause}
-
-Une requête avec l' `LIMIT n BY expressions` la clause sélectionne le premier `n` lignes pour chaque valeur distincte de `expressions`. La clé pour `LIMIT BY` peut contenir n'importe quel nombre de [expression](../../syntax.md#syntax-expressions).
-
-ClickHouse prend en charge les variantes de syntaxe suivantes:
-
--   `LIMIT [offset_value, ]n BY expressions`
--   `LIMIT n OFFSET offset_value BY expressions`
-
-Pendant le traitement de la requête, ClickHouse sélectionne les données classées par clé de tri. La clé de tri est définie explicitement à l'aide [ORDER BY](order-by.md) clause ou implicitement en tant que propriété du moteur de table. Puis clickhouse s'applique `LIMIT n BY expressions` et renvoie le premier `n` lignes pour chaque combinaison distincte de `expressions`. Si `OFFSET` est spécifié, puis pour chaque bloc de données qui appartient à une combinaison particulière de `expressions`, Clickhouse saute `offset_value` nombre de lignes depuis le début du bloc et renvoie un maximum de `n` les lignes en conséquence. Si `offset_value` est plus grand que le nombre de lignes dans le bloc de données, ClickHouse renvoie zéro lignes du bloc.
-
-!!! note "Note"
-    `LIMIT BY` n'est pas liée à [LIMIT](limit.md). Ils peuvent tous deux être utilisés dans la même requête.
-
-## Exemple {#examples}
-
-Exemple de table:
-
-``` sql
-CREATE TABLE limit_by(id Int, val Int) ENGINE = Memory;
-INSERT INTO limit_by VALUES (1, 10), (1, 11), (1, 12), (2, 20), (2, 21);
-```
-
-Requête:
-
-``` sql
-SELECT * FROM limit_by ORDER BY id, val LIMIT 2 BY id
-```
-
-``` text
-┌─id─┬─val─┐
-│  1 │  10 │
-│  1 │  11 │
-│  2 │  20 │
-│  2 │  21 │
-└────┴─────┘
-```
-
-``` sql
-SELECT * FROM limit_by ORDER BY id, val LIMIT 1, 2 BY id
-```
-
-``` text
-┌─id─┬─val─┐
-│  1 │  11 │
-│  1 │  12 │
-│  2 │  21 │
-└────┴─────┘
-```
-
-Le `SELECT * FROM limit_by ORDER BY id, val LIMIT 2 OFFSET 1 BY id` requête renvoie le même résultat.
-
-La requête suivante renvoie les 5 principaux référents pour chaque `domain, device_type` paire avec un maximum de 100 lignes au total (`LIMIT n BY + LIMIT`).
-
-``` sql
-SELECT
-    domainWithoutWWW(URL) AS domain,
-    domainWithoutWWW(REFERRER_URL) AS referrer,
-    device_type,
-    count() cnt
-FROM hits
-GROUP BY domain, referrer, device_type
-ORDER BY cnt DESC
-LIMIT 5 BY domain, device_type
-LIMIT 100
-```

-# Clause ORDER BY {#select-order-by}
-
-Le `ORDER BY` clause contient une liste des expressions, qui peuvent être attribuées avec `DESC` (décroissant) ou `ASC` modificateur (ascendant) qui détermine la direction de tri. Si la direction n'est pas spécifié, `ASC` est supposé, donc il est généralement omis. La direction de tri s'applique à une seule expression, pas à la liste entière. Exemple: `ORDER BY Visits DESC, SearchPhrase`
-
-Les lignes qui ont des valeurs identiques pour la liste des expressions de tri sont sorties dans un ordre arbitraire, qui peut également être non déterministe (différent à chaque fois).
-Si la clause ORDER BY est omise, l'ordre des lignes est également indéfini et peut également être non déterministe.
-
-## Tri des valeurs spéciales {#sorting-of-special-values}
-
-Il existe deux approches pour `NaN` et `NULL` ordre de tri:
-
--   Par défaut ou avec le `NULLS LAST` modificateur: d'abord les valeurs, puis `NaN`, puis `NULL`.
--   Avec l' `NULLS FIRST` modificateur: première `NULL`, puis `NaN` puis d'autres valeurs.
-
-### Exemple {#example}
-
-Pour la table
-
-``` text

-└───┴──────┘
-```
-
-Lorsque les nombres à virgule flottante sont triés, les Nan sont séparés des autres valeurs. Quel que soit l'ordre de tri, NaNs viennent à la fin. En d'autres termes, pour le Tri ascendant, ils sont placés comme s'ils étaient plus grands que tous les autres nombres, tandis que pour le Tri descendant, ils sont placés comme s'ils étaient plus petits que les autres.
-
-## Classement De Soutien {#collation-support}
-
-Pour le tri par valeurs de chaîne, vous pouvez spécifier le classement (comparaison). Exemple: `ORDER BY SearchPhrase COLLATE 'tr'` - pour le tri par mot-clé dans l'ordre croissant, en utilisant l'alphabet turc, insensible à la casse, en supposant que les chaînes sont encodées en UTF-8. COLLATE peut être spécifié ou non pour chaque expression dans L'ordre par indépendamment. Si ASC ou DESC est spécifié, COLLATE est spécifié après. Lors de L'utilisation de COLLATE, le tri est toujours insensible à la casse.
-
-Nous recommandons uniquement D'utiliser COLLATE pour le tri final d'un petit nombre de lignes, car le tri avec COLLATE est moins efficace que le tri normal par octets.
-
-## Détails De Mise En Œuvre {#implementation-details}
-
-Moins de RAM est utilisé si un assez petit [LIMIT](limit.md) est précisée en plus `ORDER BY`. Sinon, la quantité de mémoire dépensée est proportionnelle au volume de données à trier. Pour le traitement des requêtes distribuées, si [GROUP BY](group-by.md) est omis, le tri est partiellement effectué sur les serveurs distants et les résultats sont fusionnés Sur le serveur demandeur. Cela signifie que pour le tri distribué, le volume de données à trier peut être supérieur à la quantité de mémoire sur un seul serveur.
-
-S'il N'y a pas assez de RAM, il est possible d'effectuer un tri dans la mémoire externe (création de fichiers temporaires sur un disque). Utilisez le paramètre `max_bytes_before_external_sort` pour ce but. S'il est défini sur 0 (par défaut), le tri externe est désactivé. Si elle est activée, lorsque le volume de données à trier atteint le nombre spécifié d'octets, les données collectées sont triés et déposés dans un fichier temporaire. Une fois toutes les données lues, tous les fichiers triés sont fusionnés et les résultats sont générés. Les fichiers sont écrits dans le `/var/lib/clickhouse/tmp/` dans la configuration (par défaut, mais vous pouvez `tmp_path` paramètre pour modifier ce paramètre).
-
-L'exécution d'une requête peut utiliser plus de mémoire que `max_bytes_before_external_sort`. Pour cette raison, ce paramètre doit avoir une valeur significativement inférieure à `max_memory_usage`. Par exemple, si votre serveur dispose de 128 Go de RAM et que vous devez exécuter une seule requête, définissez `max_memory_usage` à 100 Go, et `max_bytes_before_external_sort` à 80 Go.
-
-Le tri externe fonctionne beaucoup moins efficacement que le tri dans la RAM.

-# Clause PREWHERE {#prewhere-clause}
-
-Prewhere est une optimisation pour appliquer le filtrage plus efficacement. Il est activé par défaut, même si `PREWHERE` la clause n'est pas explicitement spécifié. Il fonctionne en déplaçant automatiquement une partie de [WHERE](where.md) condition à prewhere étape. Le rôle de `PREWHERE` la clause est seulement pour contrôler cette optimisation si vous pensez que vous savez comment le faire mieux que par défaut.
-
-Avec l'optimisation prewhere, au début, seules les colonnes nécessaires à l'exécution de l'expression prewhere sont lues. Ensuite, les autres colonnes sont lues qui sont nécessaires pour exécuter le reste de la requête, mais seulement les blocs où l'expression prewhere est “true” au moins pour certaines lignes. S'il y a beaucoup de blocs où prewhere expression est “false” pour toutes les lignes et prewhere a besoin de moins de colonnes que les autres parties de la requête, cela permet souvent de lire beaucoup moins de données à partir du disque pour l'exécution de la requête.
-
-## Contrôle Manuel De Prewhere {#controlling-prewhere-manually}
-
-La clause a le même sens que la `WHERE` clause. La différence est dans laquelle les données sont lues à partir de la table. Quand à commander manuellement `PREWHERE` pour les conditions de filtration qui sont utilisées par une minorité des colonnes de la requête, mais qui fournissent une filtration de données forte. Cela réduit le volume de données à lire.
-
-Une requête peut spécifier simultanément `PREWHERE` et `WHERE`. Dans ce cas, `PREWHERE` précéder `WHERE`.
-
-Si l' `optimize_move_to_prewhere` le paramètre est défini sur 0, heuristiques pour déplacer automatiquement des parties d'expressions `WHERE` de `PREWHERE` sont désactivés.
-
-## Limitation {#limitations}
-
-`PREWHERE` est uniquement pris en charge par les tables `*MergeTree` famille.

-# Exemple de Clause {#select-sample-clause}
-
-Le `SAMPLE` clause permet approchée `SELECT` le traitement de la requête.
-
-Lorsque l'échantillonnage de données est activé, la requête n'est pas effectuée sur toutes les données, mais uniquement sur une certaine fraction de données (échantillon). Par exemple, si vous avez besoin de calculer des statistiques pour toutes les visites, il suffit d'exécuter la requête sur le 1/10 de la fraction de toutes les visites, puis multiplier le résultat par 10.
-
-Le traitement approximatif des requêtes peut être utile dans les cas suivants:
-
--   Lorsque vous avez des exigences de synchronisation strictes (comme \<100ms), mais que vous ne pouvez pas justifier le coût des ressources matérielles supplémentaires pour y répondre.
--   Lorsque vos données brutes ne sont pas précises, l'approximation ne dégrade pas sensiblement la qualité.
--   Les exigences commerciales ciblent des résultats approximatifs (pour la rentabilité, ou pour commercialiser des résultats exacts aux utilisateurs premium).
-
-!!! note "Note"
-    Vous ne pouvez utiliser l'échantillonnage qu'avec les tables [MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md) famille, et seulement si l'expression d'échantillonnage a été spécifiée lors de la création de la table (voir [Moteur MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table)).
-
-Les caractéristiques de l'échantillonnage des données sont énumérées ci-dessous:
-
--   L'échantillonnage de données est un mécanisme déterministe. Le résultat de la même `SELECT .. SAMPLE` la requête est toujours le même.
--   L'échantillonnage fonctionne de manière cohérente pour différentes tables. Pour les tables avec une seule clé d'échantillonnage, un échantillon avec le même coefficient sélectionne toujours le même sous-ensemble de données possibles. Par exemple, un exemple d'ID utilisateur prend des lignes avec le même sous-ensemble de tous les ID utilisateur possibles de différentes tables. Cela signifie que vous pouvez utiliser l'exemple dans les sous-requêtes dans la [IN](../../operators/in.md) clause. En outre, vous pouvez joindre des échantillons en utilisant le [JOIN](join.md) clause.
--   L'échantillonnage permet de lire moins de données à partir d'un disque. Notez que vous devez spécifier l'échantillonnage clé correctement. Pour plus d'informations, voir [Création d'une Table MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table).
-
-Pour l' `SAMPLE` clause la syntaxe suivante est prise en charge:
-
-| SAMPLE Clause Syntax | Description                                                                                                                                                                                                                                                                 |
-|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `SAMPLE k`           | Ici `k` est le nombre de 0 à 1.</br>La requête est exécutée sur `k` fraction des données. Exemple, `SAMPLE 0.1` exécute la requête sur 10% des données. [Lire plus](#select-sample-k)                                                                                       |
-| `SAMPLE n`           | Ici `n` est un entier suffisamment grand.</br>La requête est exécutée sur un échantillon d'au moins `n` lignes (mais pas significativement plus que cela). Exemple, `SAMPLE 10000000` exécute la requête sur un minimum de 10 000 000 lignes. [Lire plus](#select-sample-n) |
-| `SAMPLE k OFFSET m`  | Ici `k` et `m` sont les nombres de 0 à 1.</br>La requête est exécutée sur un échantillon de `k` fraction des données. Les données utilisées pour l'échantillon est compensée par `m` fraction. [Lire plus](#select-sample-offset)                                           |
-
-## SAMPLE K {#select-sample-k}
-
-Ici `k` est le nombre de 0 à 1 (les notations fractionnaires et décimales sont prises en charge). Exemple, `SAMPLE 1/2` ou `SAMPLE 0.5`.
-
-Dans un `SAMPLE k` clause, l'échantillon est prélevé à partir de la `k` fraction des données. L'exemple est illustré ci-dessous:
-
-``` sql
-SELECT
-    Title,
-    count() * 10 AS PageViews
-FROM hits_distributed
-SAMPLE 0.1
-WHERE
-    CounterID = 34
-GROUP BY Title
-ORDER BY PageViews DESC LIMIT 1000
-```
-
-Dans cet exemple, la requête est exécutée sur un échantillon de 0,1 (10%) de données. Les valeurs des fonctions d'agrégat ne sont pas corrigées automatiquement, donc pour obtenir un résultat approximatif, la valeur `count()` est multiplié manuellement par 10.
-
-## SAMPLE N {#select-sample-n}
-
-Ici `n` est un entier suffisamment grand. Exemple, `SAMPLE 10000000`.
-
-Dans ce cas, la requête est exécutée sur un échantillon d'au moins `n` lignes (mais pas significativement plus que cela). Exemple, `SAMPLE 10000000` exécute la requête sur un minimum de 10 000 000 lignes.
-
-Puisque l'unité minimale pour la lecture des données est un granule (sa taille est définie par le `index_granularity` de réglage), il est logique de définir un échantillon beaucoup plus grand que la taille du granule.
-
-Lors de l'utilisation de la `SAMPLE n` clause, vous ne savez pas quel pourcentage relatif de données a été traité. Donc, vous ne connaissez pas le coefficient par lequel les fonctions agrégées doivent être multipliées. L'utilisation de la `_sample_factor` colonne virtuelle pour obtenir le résultat approximatif.
-
-Le `_sample_factor` colonne contient des coefficients relatifs qui sont calculés dynamiquement. Cette colonne est créée automatiquement lorsque vous [créer](../../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-creating-a-table) une table avec la clé d'échantillonnage spécifiée. Les exemples d'utilisation de la `_sample_factor` colonne sont indiqués ci-dessous.
-
-Considérons la table `visits` qui contient des statistiques sur les visites de site. Le premier exemple montre comment calculer le nombre de pages vues:
-
-``` sql
-SELECT sum(PageViews * _sample_factor)
-FROM visits
-SAMPLE 10000000
-```
-
-L'exemple suivant montre comment calculer le nombre total de visites:
-
-``` sql
-SELECT sum(_sample_factor)
-FROM visits
-SAMPLE 10000000
-```
-
-L'exemple ci-dessous montre comment calculer la durée moyenne de la session. Notez que vous n'avez pas besoin d'utiliser le coefficient relatif pour calculer les valeurs moyennes.
-
-``` sql
-SELECT avg(Duration)
-FROM visits
-SAMPLE 10000000
-```
-
-## SAMPLE K OFFSET M {#select-sample-offset}
-
-Ici `k` et `m` sont des nombres de 0 à 1. Des exemples sont présentés ci-dessous.
-
-**Exemple 1**
-
-``` sql
-SAMPLE 1/10
-```
-
-Dans cet exemple, l'échantillon représente 1 / 10e de toutes les données:
-
-`[++------------]`
-
-**Exemple 2**
-
-``` sql
-SAMPLE 1/10 OFFSET 1/2
-```
-
-Ici, un échantillon de 10% est prélevé à partir de la seconde moitié des données.

-Les colonnes de résultat sont appariées par leur index (ordre intérieur `SELECT`). Si les noms de colonne ne correspondent pas, les noms du résultat final sont tirés de la première requête.
-
-La coulée de Type est effectuée pour les syndicats. Par exemple, si deux requêtes combinées ont le même champ avec non-`Nullable` et `Nullable` types d'un type compatible, la `UNION ALL` a un `Nullable` type de champ.
-
-Requêtes qui font partie de `UNION ALL` ne peut pas être placée entre parenthèses. [ORDER BY](order-by.md) et [LIMIT](limit.md) sont appliqués à des requêtes séparées, pas au résultat final. Si vous devez appliquer une conversion au résultat final, vous pouvez mettre toutes les requêtes avec `UNION ALL` dans une sous-requête dans la [FROM](from.md) clause.
-
-## Limitation {#limitations}
-
-Seulement `UNION ALL` est pris en charge. Régulier `UNION` (`UNION DISTINCT`) n'est pas pris en charge. Si vous avez besoin d' `UNION DISTINCT`, vous pouvez écrire `SELECT DISTINCT` à partir d'une sous-requête contenant `UNION ALL`.
-
-## Détails De Mise En Œuvre {#implementation-details}
-
-Requêtes qui font partie de `UNION ALL` peuvent être exécutées simultanément, et leurs résultats peuvent être mélangés ensemble.

-# Clause where {#select-where}
-
-`WHERE` clause permet de filtrer les données en provenance de [FROM](from.md) la clause de `SELECT`.
-
-Si il y a un `WHERE` , il doit contenir une expression avec la `UInt8` type. C'est généralement une expression avec comparaison et opérateurs logiques. Les lignes où cette expression est évaluée à 0 sont exclues des transformations ou des résultats ultérieurs.
-
-`WHERE` expression est évaluée sur la possibilité d'utiliser des index et l'élagage de partition, si le moteur de table sous-jacent le prend en charge.
-
-!!! note "Note"
-    Il y a une optimisation de filtrage appelée [prewhere](prewhere.md).

-# AVEC la Clause {#with-clause}
-
-Cette section prend en charge les Expressions de Table courantes ([CTE](https://en.wikipedia.org/wiki/Hierarchical_and_recursive_queries_in_SQL)), de sorte que les résultats de `WITH` la clause peut être utilisé à l'intérieur `SELECT` clause.
-
-## Limitation {#limitations}
-
-1.  Les requêtes récursives ne sont pas prises en charge.
-2.  Lorsque la sous-requête est utilisée à l'intérieur avec section, son résultat doit être scalaire avec exactement une ligne.
-3.  Les résultats d'Expression ne sont pas disponibles dans les sous-requêtes.
-
-## Exemple {#examples}
-
-**Exemple 1:** Utilisation d'une expression constante comme “variable”
-
-``` sql
-WITH '2019-08-01 15:23:00' as ts_upper_bound
-SELECT *
-FROM hits
-WHERE
-    EventDate = toDate(ts_upper_bound) AND
-    EventTime <= ts_upper_bound
-```
-
-**Exemple 2:** De les expulser, somme(octets) résultat de l'expression de clause SELECT de la liste de colonnes
-
-``` sql
-WITH sum(bytes) as s
-SELECT
-    formatReadableSize(s),
-    table
-FROM system.parts
-GROUP BY table
-ORDER BY s
-```
-
-**Exemple 3:** Utilisation des résultats de la sous-requête scalaire
-
-``` sql
-/* this example would return TOP 10 of most huge tables */
-WITH
-    (
-        SELECT sum(bytes)
-        FROM system.parts
-        WHERE active
-    ) AS total_disk_usage
-SELECT
-    (sum(bytes) / total_disk_usage) * 100 AS table_disk_usage,
-    table
-FROM system.parts
-GROUP BY table
-ORDER BY table_disk_usage DESC
-LIMIT 10
-```
-
-**Exemple 4:** Réutilisation de l'expression dans la sous-requête
-
-Comme solution de contournement pour la limitation actuelle de l'utilisation de l'expression dans les sous-requêtes, Vous pouvez la dupliquer.
-
-``` sql
-WITH ['hello'] AS hello
-SELECT
-    hello,
-    *
-FROM
-(
-    WITH ['hello'] AS hello
-    SELECT hello
-)
-```
-
-``` text
-┌─hello─────┬─hello─────┐
-│ ['hello'] │ ['hello'] │
-└───────────┴───────────┘

-
-## RELOAD DICTIONARIES {#query_language-system-reload-dictionaries}
-
-Recharge tous les dictionnaires qui ont déjà été chargés avec succès.
-Par défaut, les dictionnaires sont chargés paresseusement (voir [dictionaries_lazy_load](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-dictionaries_lazy_load)), donc au lieu d'être chargés automatiquement au démarrage, ils sont initialisés lors du premier accès via la fonction dictGet ou sélectionnez dans les tables avec ENGINE = Dictionary . Le `SYSTEM RELOAD DICTIONARIES` query recharge ces dictionnaires (chargés).
-Retourne toujours `Ok.` quel que soit le résultat de la mise à jour du dictionnaire.
-
-## Recharger le dictionnaire Dictionary_name {#query_language-system-reload-dictionary}
-
-Recharge complètement un dictionnaire `dictionary_name`, quel que soit l'état du dictionnaire (LOADED / NOT_LOADED / FAILED).
-Retourne toujours `Ok.` quel que soit le résultat de la mise à jour du dictionnaire.
-L'état du dictionnaire peut être vérifié en interrogeant le `system.dictionaries` table.
-
-``` sql
-SELECT name, status FROM system.dictionaries;
-```
-
-## DROP DNS CACHE {#query_language-system-drop-dns-cache}
-
-Réinitialise le cache DNS interne de ClickHouse. Parfois (pour les anciennes versions de ClickHouse), il est nécessaire d'utiliser cette commande lors de la modification de l'infrastructure (modification de l'adresse IP d'un autre serveur ClickHouse ou du serveur utilisé par les dictionnaires).
-
-Pour une gestion du cache plus pratique (automatique), voir paramètres disable_internal_dns_cache, dns_cache_update_period.
-
-## DROP MARK CACHE {#query_language-system-drop-mark-cache}
-
-Réinitialise le cache de marque. Utilisé dans le développement de ClickHouse et des tests de performance.
-
-## FLUSH LOGS {#query_language-system-flush_logs}
-
-Flushes buffers of log messages to system tables (e.g. system.query_log). Allows you to not wait 7.5 seconds when debugging.
-
-## RELOAD CONFIG {#query_language-system-reload-config}
-
-Recharge la configuration de ClickHouse. Utilisé lorsque la configuration est stockée dans ZooKeeeper.
-
-## SHUTDOWN {#query_language-system-shutdown}
-
-Normalement ferme ClickHouse (comme `service clickhouse-server stop` / `kill {$pid_clickhouse-server}`)
-
-## KILL {#query_language-system-kill}
-
-Annule le processus de ClickHouse (comme `kill -9 {$ pid_clickhouse-server}`)
-
-## Gestion Des Tables Distribuées {#query-language-system-distributed}
-
-ClickHouse peut gérer [distribué](../../engines/table-engines/special/distributed.md) table. Lorsqu'un utilisateur insère des données dans ces tables, ClickHouse crée d'abord une file d'attente des données qui doivent être envoyées aux nœuds de cluster, puis l'envoie de manière asynchrone. Vous pouvez gérer le traitement des files d'attente avec [STOP DISTRIBUTED SENDS](#query_language-system-stop-distributed-sends), [FLUSH DISTRIBUTED](#query_language-system-flush-distributed), et [START DISTRIBUTED SENDS](#query_language-system-start-distributed-sends) requête. Vous pouvez également insérer de manière synchrone des données distribuées avec `insert_distributed_sync` paramètre.
-
-### STOP DISTRIBUTED SENDS {#query_language-system-stop-distributed-sends}
-
-Désactive la distribution de données en arrière-plan lors de l'insertion de données dans des tables distribuées.
-
-``` sql
-SYSTEM STOP DISTRIBUTED SENDS [db.]<distributed_table_name>
-```
-
-### FLUSH DISTRIBUTED {#query_language-system-flush-distributed}
-
-Force ClickHouse à envoyer des données aux nœuds de cluster de manière synchrone. Si des nœuds ne sont pas disponibles, ClickHouse lève une exception et arrête l'exécution de la requête. Vous pouvez réessayer la requête jusqu'à ce qu'elle réussisse, ce qui se produira lorsque tous les nœuds seront de nouveau en ligne.
-
-``` sql
-SYSTEM FLUSH DISTRIBUTED [db.]<distributed_table_name>
-```
-
-### START DISTRIBUTED SENDS {#query_language-system-start-distributed-sends}
-
-Active la distribution de données en arrière-plan lors de l'insertion de données dans des tables distribuées.
-
-``` sql
-SYSTEM START DISTRIBUTED SENDS [db.]<distributed_table_name>
-```
-
-### STOP MERGES {#query_language-system-stop-merges}
-
-Offre la possibilité d'arrêter les fusions d'arrière-plan pour les tables de la famille MergeTree:
-
-``` sql
-SYSTEM STOP MERGES [[db.]merge_tree_family_table_name]
-```
-
-!!! note "Note"
-    `DETACH / ATTACH` table va commencer les fusions d'arrière-plan pour la table même dans le cas où les fusions ont été arrêtées pour toutes les tables MergeTree auparavant.
-
-### START MERGES {#query_language-system-start-merges}
-
-Offre la possibilité de démarrer des fusions en arrière-plan pour les tables de la famille MergeTree:
-
-``` sql
-SYSTEM START MERGES [[db.]merge_tree_family_table_name]
-```

-toc_title: Syntaxe
----
-
-# Syntaxe {#syntax}
-
-Il existe deux types d'analyseurs dans le système: L'analyseur SQL complet (un analyseur de descente récursif) et l'analyseur de format de données (un analyseur de flux rapide).
-Dans tous les cas à l'exception de la `INSERT` requête, seul L'analyseur SQL complet est utilisé.
-Le `INSERT` requête utilise les deux analyseurs:
-
-``` sql
-INSERT INTO t VALUES (1, 'Hello, world'), (2, 'abc'), (3, 'def')
-```
-
-Le `INSERT INTO t VALUES` fragment est analysé par l'analyseur complet, et les données `(1, 'Hello, world'), (2, 'abc'), (3, 'def')` est analysé par l'analyseur de flux rapide. Vous pouvez également activer l'analyseur complet pour les données à l'aide de la [input_format_values_interpret_expressions](../operations/settings/settings.md#settings-input_format_values_interpret_expressions) paramètre. Lorsque `input_format_values_interpret_expressions = 1`, ClickHouse essaie d'abord d'analyser les valeurs avec l'analyseur de flux rapide. S'il échoue, ClickHouse essaie d'utiliser l'analyseur complet pour les données, en le traitant comme un SQL [expression](#syntax-expressions).
-
-Les données peuvent avoir n'importe quel format. Lorsqu'une requête est reçue, le serveur calcule pas plus que [max_query_size](../operations/settings/settings.md#settings-max_query_size) octets de la requête en RAM (par défaut, 1 Mo), et le reste est analysé en flux.
-Il permet d'éviter les problèmes avec de grandes `INSERT` requête.
-
-Lors de l'utilisation de la `Values` format dans un `INSERT` de la requête, il peut sembler que les données sont analysées de même que les expressions dans un `SELECT` requête, mais ce n'est pas vrai. Le `Values` le format est beaucoup plus limitée.
-
-Le reste de cet article couvre l'analyseur complet. Pour plus d'informations sur les analyseurs de format, consultez [Format](../interfaces/formats.md) section.
-
-## Espace {#spaces}
-
-Il peut y avoir n'importe quel nombre de symboles d'espace entre les constructions syntaxiques (y compris le début et la fin d'une requête). Les symboles d'espace incluent l'espace, l'onglet, le saut de ligne, Le CR et le flux de formulaire.
-
-## Commentaire {#comments}
-
-ClickHouse prend en charge les commentaires de style SQL et de style C.
-Les commentaires de style SQL commencent par `--` et continuer jusqu'à la fin de la ligne, un espace après `--` peut être omis.
-C-style sont de `/*` de `*/`et peut être multiligne, les espaces ne sont pas requis non plus.
-
-## Mot {#syntax-keywords}
-
-Les mots clés sont insensibles à la casse lorsqu'ils correspondent à:
-
--   La norme SQL. Exemple, `SELECT`, `select` et `SeLeCt` sont toutes valides.
--   Implémentation dans certains SGBD populaires (MySQL ou Postgres). Exemple, `DateTime` est le même que `datetime`.
-
-Si le nom du type de données est sensible à la casse peut être vérifié `system.data_type_families` table.
-
-Contrairement à SQL standard, tous les autres mots clés (y compris les noms de fonctions) sont **sensible à la casse**.
-
-Mots-clés ne sont pas réservés; ils sont traités comme tels que dans le contexte correspondant. Si vous utilisez [identificateur](#syntax-identifiers) avec le même nom que les mots-clés, placez-les entre guillemets doubles ou backticks. Par exemple, la requête `SELECT "FROM" FROM table_name` est valide si la table `table_name` a colonne avec le nom de `"FROM"`.
-
-## Identificateur {#syntax-identifiers}
-
-Les identificateurs sont:
-
--   Noms de Cluster, de base de données, de table, de partition et de colonne.
--   Fonction.
--   Types de données.
--   [Expression des alias](#syntax-expression_aliases).
-
-Les identificateurs peuvent être cités ou non cités. Ce dernier est préféré.
-
-Non identificateurs doivent correspondre à l'expression régulière `^[a-zA-Z_][0-9a-zA-Z_]*$` et ne peut pas être égale à [mot](#syntax-keywords). Exemple: `x, _1, X_y__Z123_.`
-
-Si vous souhaitez utiliser les identifiants de la même manière que les mots-clés ou si vous souhaitez utiliser d'autres symboles dans les identifiants, citez-le en utilisant des guillemets doubles ou des backticks, par exemple, `"id"`, `` `id` ``.
-
-## Littéral {#literals}
-
-Il y a numérique, chaîne de caractères, composé, et `NULL` littéral.
-
-### Numérique {#numeric}
-
-Littéral numérique tente d'être analysé:
-
--   Tout d'abord, comme un nombre signé 64 bits, en utilisant le [strtoull](https://en.cppreference.com/w/cpp/string/byte/strtoul) fonction.
--   En cas d'échec, en tant que nombre non signé 64 bits, [strtoll](https://en.cppreference.com/w/cpp/string/byte/strtol) fonction.
--   En cas d'échec, en tant que nombre à virgule flottante [strtod](https://en.cppreference.com/w/cpp/string/byte/strtof) fonction.
--   Sinon, elle renvoie une erreur.
-
-La valeur littérale a le plus petit type dans lequel la valeur correspond.
-Par exemple, 1 est analysé comme `UInt8`, mais 256 est analysé comme `UInt16`. Pour plus d'informations, voir [Types de données](../sql-reference/data-types/index.md).
-
-Exemple: `1`, `18446744073709551615`, `0xDEADBEEF`, `01`, `0.1`, `1e100`, `-1e-100`, `inf`, `nan`.
-
-### Chaîne {#syntax-string-literal}
-
-Seuls les littéraux de chaîne entre guillemets simples sont pris en charge. Le clos de caractères barre oblique inverse échappé. Les séquences d'échappement suivantes ont une valeur spéciale correspondante: `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\a`, `\v`, `\xHH`. Dans tous les autres cas, des séquences d'échappement au format `\c`, où `c` est un caractère, sont convertis à `c`. Cela signifie que vous pouvez utiliser les séquences `\'`et`\\`. La valeur aurez l' [Chaîne](../sql-reference/data-types/string.md) type.
-
-Dans les littéraux de chaîne, vous devez vous échapper d'au moins `'` et `\`. Les guillemets simples peuvent être échappés avec le guillemet simple, littéraux `'It\'s'` et `'It''s'` sont égaux.
-
-### Composé {#compound}
-
-Les tableaux sont construits avec des crochets `[1, 2, 3]`. Nuples sont construits avec des supports ronds `(1, 'Hello, world!', 2)`.
-Techniquement, ce ne sont pas des littéraux, mais des expressions avec l'opérateur de création de tableau et l'opérateur de création de tuple, respectivement.
-Un tableau doit être composé d'au moins un élément, et un tuple doit avoir au moins deux éléments.
-Il y a un cas distinct lorsque les tuples apparaissent dans le `IN` clause de a `SELECT` requête. Les résultats de la requête peuvent inclure des tuples, mais les tuples ne peuvent pas être enregistrés dans une base de données (à l'exception des tables avec [Mémoire](../engines/table-engines/special/memory.md) moteur).
-
-### NULL {#null-literal}
-
-Indique que la valeur est manquante.
-
-Afin de stocker `NULL` dans un champ de table, il doit être de la [Nullable](../sql-reference/data-types/nullable.md) type.
-
-Selon le format de données (entrée ou sortie), `NULL` peut avoir une représentation différente. Pour plus d'informations, consultez la documentation de [formats de données](../interfaces/formats.md#formats).
-
-Il y a beaucoup de nuances au traitement `NULL`. Par exemple, si au moins l'un des arguments d'une opération de comparaison est `NULL` le résultat de cette opération est également `NULL`. Il en va de même pour la multiplication, l'addition et d'autres opérations. Pour plus d'informations, lisez la documentation pour chaque opération.
-
-Dans les requêtes, vous pouvez vérifier `NULL` à l'aide de la [IS NULL](operators/index.md#operator-is-null) et [IS NOT NULL](operators/index.md) opérateurs et les fonctions connexes `isNull` et `isNotNull`.
-
-## Fonction {#functions}
-
-Les appels de fonction sont écrits comme un identifiant avec une liste d'arguments (éventuellement vide) entre parenthèses. Contrairement à SQL standard, les crochets sont requis, même pour une liste d'arguments vide. Exemple: `now()`.
-Il existe des fonctions régulières et agrégées (voir la section “Aggregate functions”). Certaines fonctions d'agrégat peut contenir deux listes d'arguments entre parenthèses. Exemple: `quantile (0.9) (x)`. Ces fonctions d'agrégation sont appelés “parametric” fonctions, et les arguments dans la première liste sont appelés “parameters”. La syntaxe des fonctions d'agrégation sans paramètres est la même que pour les fonctions régulières.
-
-## Opérateur {#operators}
-
-Les opérateurs sont convertis en leurs fonctions correspondantes lors de l'analyse des requêtes, en tenant compte de leur priorité et de leur associativité.
-Par exemple, l'expression `1 + 2 * 3 + 4` est transformé à `plus(plus(1, multiply(2, 3)), 4)`.
-
-## Types de données et moteurs de Table de base de données {#data_types-and-database-table-engines}
-
-Types de données et moteurs de table dans `CREATE` les requêtes sont écrites de la même manière que les identifiants ou les fonctions. En d'autres termes, ils peuvent ou ne peuvent pas contenir une liste d'arguments entre parenthèses. Pour plus d'informations, voir les sections “Data types,” “Table engines,” et “CREATE”.
-
-## Expression Des Alias {#syntax-expression_aliases}
-
-Un alias est un nom défini par l'utilisateur pour l'expression dans une requête.
-
-``` sql
-expr AS alias
-```
-
--   `AS` — The keyword for defining aliases. You can define the alias for a table name or a column name in a `SELECT` clause sans utiliser le `AS` mot.
-
-        For example, `SELECT table_name_alias.column_name FROM table_name table_name_alias`.
-
-        In the [CAST](sql_reference/functions/type_conversion_functions.md#type_conversion_function-cast) function, the `AS` keyword has another meaning. See the description of the function.
-
--   `expr` — Any expression supported by ClickHouse.
-
-        For example, `SELECT column_name * 2 AS double FROM some_table`.
-
--   `alias` — Name for `expr`. Les alias doivent être conformes à la [identificateur](#syntax-identifiers) syntaxe.
-
-        For example, `SELECT "table t".column_name FROM table_name AS "table t"`.
-
-### Notes sur l'Utilisation de la {#notes-on-usage}
-
-Les alias sont globaux pour une requête ou d'une sous-requête, vous pouvez définir un alias dans n'importe quelle partie d'une requête de toute expression. Exemple, `SELECT (1 AS n) + 2, n`.
-
-Les alias ne sont pas visibles dans les sous-requêtes et entre les sous-requêtes. Par exemple, lors de l'exécution de la requête `SELECT (SELECT sum(b.a) + num FROM b) - a.a AS num FROM a` Clickhouse génère l'exception `Unknown identifier: num`.
-
-Si un alias est défini pour les colonnes de `SELECT` la clause d'une sous-requête, ces colonnes sont visibles dans la requête externe. Exemple, `SELECT n + m FROM (SELECT 1 AS n, 2 AS m)`.
-
-Soyez prudent avec les Alias qui sont les mêmes que les noms de colonnes ou de tables. Considérons l'exemple suivant:
-
-``` sql
-CREATE TABLE t
-(
-    a Int,
-    b Int
-)
-ENGINE = TinyLog()
-```
-
-``` sql
-SELECT
-    argMax(a, b),
-    sum(b) AS b
-FROM t
-```
-
-``` text
-Received exception from server (version 18.14.17):
-Code: 184. DB::Exception: Received from localhost:9000, 127.0.0.1. DB::Exception: Aggregate function sum(b) is found inside another aggregate function in query.
-```
-
-Dans cet exemple, nous avons déclaré table `t` avec la colonne `b`. Ensuite, lors de la sélection des données, nous avons défini le `sum(b) AS b` alias. Comme les alias sont globaux, ClickHouse a substitué le littéral `b` dans l'expression `argMax(a, b)` avec l'expression `sum(b)`. Cette substitution a provoqué l'exception.
-
-## Astérisque {#asterisk}
-
-Dans un `SELECT` requête, un astérisque peut remplacer l'expression. Pour plus d'informations, consultez la section “SELECT”.
-
-## Expression {#syntax-expressions}
-
-Une expression est une fonction, un identifiant, un littéral, une application d'un opérateur, une expression entre parenthèses, une sous-requête ou un astérisque. Il peut également contenir un alias.
-Une liste des expressions est une ou plusieurs expressions séparées par des virgules.
-Les fonctions et les opérateurs, à leur tour, peuvent avoir des expressions comme arguments.

-# entrée {#input}
-
-`input(structure)` - fonction de table qui permet effectivement convertir et insérer des données envoyées à la
-serveur avec une structure donnée à la table avec une autre structure.
-
-`structure` - structure de données envoyées au serveur dans le format suivant `'column1_name column1_type, column2_name column2_type, ...'`.
-Exemple, `'id UInt32, name String'`.
-
-Cette fonction peut être utilisée uniquement dans `INSERT SELECT` requête et une seule fois mais se comporte autrement comme une fonction de table ordinaire
-(par exemple, il peut être utilisé dans la sous-requête, etc.).
-
-Les données peuvent être envoyées de quelque manière que ce soit comme pour ordinaire `INSERT` requête et passé dans tout disponible [format](../../interfaces/formats.md#formats)
-qui doit être spécifié à la fin de la requête (contrairement à l'ordinaire `INSERT SELECT`).
-
-La caractéristique principale de cette fonction est que lorsque le serveur reçoit des données du client il les convertit simultanément
-selon la liste des expressions dans le `SELECT` clause et insère dans la table cible. Table temporaire
-avec toutes les données transférées n'est pas créé.
-
-**Exemple**
-
--   Laissez le `test` le tableau a la structure suivante `(a String, b String)`
-    et les données `data.csv` a une structure différente `(col1 String, col2 Date, col3 Int32)`. Requête pour insérer
-    les données de l' `data.csv` dans le `test` table avec conversion simultanée ressemble à ceci:
-
-<!-- -->
-
-``` bash
-$ cat data.csv | clickhouse-client --query="INSERT INTO test SELECT lower(col1), col3 * col3 FROM input('col1 String, col2 Date, col3 Int32') FORMAT CSV";
-```
-
--   Si `data.csv` contient les données de la même structure `test_structure` comme la table `test` puis ces deux requêtes sont égales:
-
-<!-- -->
-
-``` bash
-$ cat data.csv | clickhouse-client --query="INSERT INTO test FORMAT CSV"
-$ cat data.csv | clickhouse-client --query="INSERT INTO test SELECT * FROM input('test_structure') FORMAT CSV"

-# mysql {#mysql}
-
-Permettre `SELECT` requêtes à effectuer sur des données stockées sur un serveur MySQL distant.
-
-``` sql
-mysql('host:port', 'database', 'table', 'user', 'password'[, replace_query, 'on_duplicate_clause']);
-```
-
-**Paramètre**
-
--   `host:port` — MySQL server address.
-
--   `database` — Remote database name.
-
--   `table` — Remote table name.
-
--   `user` — MySQL user.
-
--   `password` — User password.
-
--   `replace_query` — Flag that converts `INSERT INTO` les requêtes de `REPLACE INTO`. Si `replace_query=1` la requête est remplacé.
-
--   `on_duplicate_clause` — The `ON DUPLICATE KEY on_duplicate_clause` expression qui est ajoutée à la `INSERT` requête.
-
-        Example: `INSERT INTO t (c1,c2) VALUES ('a', 2) ON DUPLICATE KEY UPDATE c2 = c2 + 1`, where `on_duplicate_clause` is `UPDATE c2 = c2 + 1`. See the MySQL documentation to find which `on_duplicate_clause` you can use with the `ON DUPLICATE KEY` clause.
-
-        To specify `on_duplicate_clause` you need to pass `0` to the `replace_query` parameter. If you simultaneously pass `replace_query = 1` and `on_duplicate_clause`, ClickHouse generates an exception.
-
-Simple `WHERE` des clauses telles que `=, !=, >, >=, <, <=` sont actuellement exécutés sur le serveur MySQL.
-
-Le reste des conditions et le `LIMIT` les contraintes d'échantillonnage sont exécutées dans ClickHouse uniquement après la fin de la requête à MySQL.
-
-**Valeur Renvoyée**
-
-Un objet table avec les mêmes colonnes que la table MySQL d'origine.
-
-## Exemple D'Utilisation {#usage-example}

-`numbers(N)` – Returns a table with the single ‘number’ colonne (UInt64) qui contient des entiers de 0 à n-1.
-`numbers(N, M)` - Retourne un tableau avec le seul ‘number’ colonne (UInt64) qui contient des entiers de N À (N + M-1).
-
-Similaire à la `system.numbers` table, il peut être utilisé pour tester et générer des valeurs successives, `numbers(N, M)` plus efficace que `system.numbers`.

-Les requêtes suivantes sont équivalentes:
-
-``` sql
-SELECT * FROM numbers(10);
-SELECT * FROM numbers(0, 10);
-SELECT * FROM system.numbers LIMIT 10;
-```

-# ODBC {#table-functions-odbc}
-
-Renvoie la table connectée via [ODBC](https://en.wikipedia.org/wiki/Open_Database_Connectivity).
-
-``` sql
-odbc(connection_settings, external_database, external_table)
-```
-
-Paramètre:
-
--   `connection_settings` — Name of the section with connection settings in the `odbc.ini` fichier.
--   `external_database` — Name of a database in an external DBMS.
--   `external_table` — Name of a table in the `external_database`.
-
-Pour implémenter en toute sécurité les connexions ODBC, ClickHouse utilise un programme distinct `clickhouse-odbc-bridge`. Si le pilote ODBC est chargé directement depuis `clickhouse-server`, les problèmes de pilote peuvent planter le serveur ClickHouse. Clickhouse démarre automatiquement `clickhouse-odbc-bridge` lorsque cela est nécessaire. Le programme ODBC bridge est installé à partir du même package que `clickhouse-server`.
-
-Les champs avec l' `NULL` les valeurs de la table externe sont converties en valeurs par défaut pour le type de données de base. Par exemple, si un champ de table MySQL distant a `INT NULL` type il est converti en 0 (la valeur par défaut pour ClickHouse `Int32` type de données).
-
-## Exemple D'Utilisation {#usage-example}
-
-**Obtenir des données de L'installation MySQL locale via ODBC**
-
-Cet exemple est vérifié pour Ubuntu Linux 18.04 et MySQL server 5.7.
-
-Assurez-vous que unixODBC et MySQL Connector sont installés.
-
-Par défaut (si installé à partir de paquets), ClickHouse démarre en tant qu'utilisateur `clickhouse`. Ainsi, vous devez créer et configurer cet utilisateur dans le serveur MySQL.
-
-``` bash
-$ sudo mysql
-```
-
-``` sql
-mysql> CREATE USER 'clickhouse'@'localhost' IDENTIFIED BY 'clickhouse';
-mysql> GRANT ALL PRIVILEGES ON *.* TO 'clickhouse'@'clickhouse' WITH GRANT OPTION;
-```
-
-Puis configurez la connexion dans `/etc/odbc.ini`.
-
-``` bash
-$ cat /etc/odbc.ini
-[mysqlconn]
-DRIVER = /usr/local/lib/libmyodbc5w.so
-SERVER = 127.0.0.1
-PORT = 3306
-DATABASE = test
-USERNAME = clickhouse
-PASSWORD = clickhouse
-```
-
-Vous pouvez vérifier la connexion en utilisant le `isql` utilitaire de l'installation unixODBC.
-
-``` bash
-$ isql -v mysqlconn
-+-------------------------+
-| Connected!                            |

-# à distance, remoteSecure {#remote-remotesecure}
-
-Vous permet d'accéder à des serveurs distants sans `Distributed` table.
-
-Signature:
-
-``` sql
-remote('addresses_expr', db, table[, 'user'[, 'password']])
-remote('addresses_expr', db.table[, 'user'[, 'password']])
-remoteSecure('addresses_expr', db, table[, 'user'[, 'password']])
-remoteSecure('addresses_expr', db.table[, 'user'[, 'password']])
-```
-
-`addresses_expr` – An expression that generates addresses of remote servers. This may be just one server address. The server address is `host:port` ou juste `host`. L'hôte peut être spécifié comme nom de serveur ou l'adresse IPv4 ou IPv6. Une adresse IPv6 est indiquée entre crochets. Le port est le port TCP sur le serveur distant. Si le port est omis, il utilise `tcp_port` à partir du fichier de configuration du serveur (par défaut, 9000).
-
-!!! important "Important"
-    Le port est requis pour une adresse IPv6.
-
-Exemple:
-
-``` text
-example01-01-1
-example01-01-1:9000
-localhost
-127.0.0.1
-[::]:9000
-[2a02:6b8:0:1111::11]:9000
-```
-
-Plusieurs adresses séparées par des virgules. Dans ce cas, ClickHouse utilisera le traitement distribué, donc il enverra la requête à toutes les adresses spécifiées (comme les fragments avec des données différentes).
-
-Exemple:
-
-``` text
-example01-01-1,example01-02-1
-```
-
-Une partie de l'expression peut être spécifiée entre crochets. L'exemple précédent peut être écrite comme suit:
-
-``` text
-example01-0{1,2}-1
-```
-
-Les accolades peuvent contenir une plage de Nombres séparés par deux points (entiers non négatifs). Dans ce cas, la gamme est étendue à un ensemble de valeurs qui génèrent fragment d'adresses. Si le premier nombre commence par zéro, les valeurs sont formées avec le même alignement zéro. L'exemple précédent peut être écrite comme suit:
-
-``` text
-example01-{01..02}-1
-```
-
-Si vous avez plusieurs paires d'accolades, il génère le produit direct des ensembles correspondants.
-
-Les adresses et les parties d'adresses entre crochets peuvent être séparées par le symbole de tuyau (\|). Dans ce cas, les ensembles correspondants de adresses sont interprétés comme des répliques, et la requête sera envoyée à la première sain réplique. Cependant, les répliques sont itérées dans l'ordre actuellement défini dans [équilibrage](../../operations/settings/settings.md) paramètre.
-
-Exemple:
-
-``` text
-example01-{01..02}-{1|2}
-```
-
-Cet exemple spécifie deux fragments qui ont chacun deux répliques.
-
-Le nombre d'adresses générées est limitée par une constante. En ce moment, c'est 1000 adresses.
-
-À l'aide de la `remote` la fonction de table est moins optimale que la création d'un `Distributed` table, car dans ce cas, la connexion au serveur est rétablie pour chaque requête. En outre, si des noms d'hôte, les noms sont résolus, et les erreurs ne sont pas comptés lors de travail avec diverses répliques. Lors du traitement d'un grand nombre de requêtes, créez toujours `Distributed` table à l'avance, et ne pas utiliser la `remote` table de fonction.
-
-Le `remote` table de fonction peut être utile dans les cas suivants:
-
--   Accès à un serveur spécifique pour la comparaison de données, le débogage et les tests.
--   Requêtes entre différents clusters ClickHouse à des fins de recherche.
--   Demandes distribuées peu fréquentes qui sont faites manuellement.
--   Distribué demandes où l'ensemble des serveurs est redéfinie à chaque fois.
-
-Si l'utilisateur n'est pas spécifié, `default` est utilisée.
-Si le mot de passe n'est spécifié, un mot de passe vide est utilisé.
-
-`remoteSecure` - la même chose que `remote` but with secured connection. Default port — [tcp_port_secure](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-tcp_port_secure) de config ou 9440.

+`SELECT` queries perform data retrieval. By default, the requested data is returned to the client, while in conjunction with [INSERT INTO](../../../sql-reference/statements/insert-into.md) it can be forwarded to a different table.
+
+## Syntax {#syntax}
+
+``` sql
+[WITH expr_list|(subquery)]
+SELECT [DISTINCT] expr_list
+[FROM [db.]table | (subquery) | table_function] [FINAL]
+[SAMPLE sample_coeff]
+[ARRAY JOIN ...]

+
+All clauses are optional, except for the required list of expressions immediately after `SELECT` which is covered in more detail [below](#select-clause).
+
+Specifics of each optional clause are covered in separate sections, which are listed in the same order as they are executed:
+
+-   [WITH clause](../../../sql-reference/statements/select/with.md)
+-   [FROM clause](../../../sql-reference/statements/select/from.md)

+-   [INTO OUTFILE clause](../../../sql-reference/statements/select/into-outfile.md)
+-   [FORMAT clause](../../../sql-reference/statements/select/format.md)
+
+## SELECT Clause {#select-clause}
+
+[Expressions](../../../sql-reference/syntax.md#syntax-expressions) specified in the `SELECT` clause are calculated after all the operations in the clauses described above are finished. These expressions work as if they apply to separate rows in the result. If expressions in the `SELECT` clause contain aggregate functions, then ClickHouse processes aggregate functions and expressions used as their arguments during the [GROUP BY](../../../sql-reference/statements/select/group-by.md) aggregation.
+
+If you want to include all columns in the result, use the asterisk (`*`) symbol. For example, `SELECT * FROM ...`.
+
+
+### COLUMNS expression {#columns-expression}
+
+To match some columns in the result with a [re2](https://en.wikipedia.org/wiki/RE2_(software)) regular expression, you can use the `COLUMNS` expression.
+
+``` sql
+COLUMNS('regexp')
+```
+
+For example, consider the table:
+
+``` sql
+CREATE TABLE default.col_names (aa Int8, ab Int8, bc Int8) ENGINE = TinyLog
+```
+
+The following query selects data from all the columns containing the `a` symbol in their name.
+
+``` sql
+SELECT COLUMNS('a') FROM col_names
+```
+
+``` text
+┌─aa─┬─ab─┐
+│  1 │  1 │
+└────┴────┘
+```
+
+The selected columns are returned not in the alphabetical order.
+
+You can use multiple `COLUMNS` expressions in a query and apply functions to them.
+
+For example:
+
+``` sql
+SELECT COLUMNS('a'), COLUMNS('c'), toTypeName(COLUMNS('c')) FROM col_names
+```
+
+``` text
+┌─aa─┬─ab─┬─bc─┬─toTypeName(bc)─┐
+│  1 │  1 │  1 │ Int8           │
+└────┴────┴────┴────────────────┘
+```
+
+Each column returned by the `COLUMNS` expression is passed to the function as a separate argument. Also you can pass other arguments to the function if it supports them. Be careful when using functions. If a function doesn’t support the number of arguments you have passed to it, ClickHouse throws an exception.
+
+For example:
+
+``` sql
+SELECT COLUMNS('a') + COLUMNS('c') FROM col_names
+```
+
+``` text
+Received exception from server (version 19.14.1):
+Code: 42. DB::Exception: Received from localhost:9000. DB::Exception: Number of arguments for function plus doesn't match: passed 3, should be 2.
+```
+
+In this example, `COLUMNS('a')` returns two columns: `aa` and `ab`. `COLUMNS('c')` returns the `bc` column. The `+` operator can’t apply to 3 arguments, so ClickHouse throws an exception with the relevant message.
+
+Columns that matched the `COLUMNS` expression can have different data types. If `COLUMNS` doesn’t match any columns and is the only expression in `SELECT`, ClickHouse throws an exception.
+
+### Asterisk {#asterisk}
+
+You can put an asterisk in any part of a query instead of an expression. When the query is analyzed, the asterisk is expanded to a list of all table columns (excluding the `MATERIALIZED` and `ALIAS` columns). There are only a few cases when using an asterisk is justified:
+
+-   When creating a table dump.
+-   For tables containing just a few columns, such as system tables.
+-   For getting information about what columns are in a table. In this case, set `LIMIT 1`. But it is better to use the `DESC TABLE` query.
+-   When there is strong filtration on a small number of columns using `PREWHERE`.
+-   In subqueries (since columns that aren’t needed for the external query are excluded from subqueries).
+
+In all other cases, we don’t recommend using the asterisk, since it only gives you the drawbacks of a columnar DBMS instead of the advantages. In other words using the asterisk is not recommended.
+
+### Extreme Values {#extreme-values}
+
+In addition to results, you can also get minimum and maximum values for the results columns. To do this, set the **extremes** setting to 1. Minimums and maximums are calculated for numeric types, dates, and dates with times. For other columns, the default values are output.
+
+An extra two rows are calculated – the minimums and maximums, respectively. These extra two rows are output in `JSON*`, `TabSeparated*`, and `Pretty*` [formats](../../../interfaces/formats.md), separate from the other rows. They are not output for other formats.
+
+In `JSON*` formats, the extreme values are output in a separate ‘extremes’ field. In `TabSeparated*` formats, the row comes after the main result, and after ‘totals’ if present. It is preceded by an empty row (after the other data). In `Pretty*` formats, the row is output as a separate table after the main result, and after `totals` if present.
+
+Extreme values are calculated for rows before `LIMIT`, but after `LIMIT BY`. However, when using `LIMIT offset, size`, the rows before `offset` are included in `extremes`. In stream requests, the result may also include a small number of rows that passed through `LIMIT`.
+
+### Notes {#notes}
+
+You can use synonyms (`AS` aliases) in any part of a query.
+
+The `GROUP BY` and `ORDER BY` clauses do not support positional arguments. This contradicts MySQL, but conforms to standard SQL. For example, `GROUP BY 1, 2` will be interpreted as grouping by constants (i.e. aggregation of all rows into one).
+
+## Implementation Details {#implementation-details}
+
+If the query omits the `DISTINCT`, `GROUP BY` and `ORDER BY` clauses and the `IN` and `JOIN` subqueries, the query will be completely stream processed, using O(1) amount of RAM. Otherwise, the query might consume a lot of RAM if the appropriate restrictions are not specified:
+
+-   `max_memory_usage`
+-   `max_rows_to_group_by`
+-   `max_rows_to_sort`
+-   `max_rows_in_distinct`
+-   `max_bytes_in_distinct`
+-   `max_rows_in_set`
+-   `max_bytes_in_set`
+-   `max_rows_in_join`
+-   `max_bytes_in_join`
+-   `max_bytes_before_external_sort`
+-   `max_bytes_before_external_group_by`
+
+For more information, see the section “Settings”. It is possible to use external sorting (saving temporary tables to a disk) and external aggregation.
+
+## SELECT modifiers {#select-modifiers}
+
+You can use the following modifiers in `SELECT` queries.
+
+### APPLY {#apply-modifier}
+
+Allows you to invoke some function for each row returned by an outer table expression of a query. 
+
+**Syntax:**
+
+``` sql
+SELECT <expr> APPLY( <func> ) FROM [db.]table_name
+```
+
+**Example:** 
+
+``` sql
+CREATE TABLE columns_transformers (i Int64, j Int16, k Int64) ENGINE = MergeTree ORDER by (i);
+INSERT INTO columns_transformers VALUES (100, 10, 324), (120, 8, 23);
+SELECT * APPLY(sum) FROM columns_transformers;
+```
+
+```
+┌─sum(i)─┬─sum(j)─┬─sum(k)─┐
+│    220 │     18 │    347 │
+└────────┴────────┴────────┘
+```
+
+### EXCEPT {#except-modifier}
+
+Specifies the names of one or more columns to exclude from the result. All matching column names are omitted from the output.
+
+**Syntax:**
+
+``` sql
+SELECT <expr> EXCEPT ( col_name1 [, col_name2, col_name3, ...] ) FROM [db.]table_name
+```
+
+**Example:**
+
+``` sql
+SELECT * EXCEPT (i) from columns_transformers;
+```
+
+```
+┌──j─┬───k─┐
+│ 10 │ 324 │
+│  8 │  23 │
+└────┴─────┘
+```
+
+### REPLACE {#replace-modifier}
+
+Specifies one or more [expression aliases](../../../sql-reference/syntax.md#syntax-expression_aliases). Each alias must match a column name from the `SELECT *` statement. In the output column list, the column that matches the alias is replaced by the expression in that `REPLACE`.
+
+This modifier does not change the names or order of columns. However, it can change the value and the value type.
+
+**Syntax:**
+
+``` sql
+SELECT <expr> REPLACE( <expr> AS col_name) from [db.]table_name
+```
+
+**Example:**
+
+``` sql
+SELECT * REPLACE(i + 1 AS i) from columns_transformers;
+```
+
+```
+┌───i─┬──j─┬───k─┐
+│ 101 │ 10 │ 324 │
+│ 121 │  8 │  23 │
+└─────┴────┴─────┘
+```
+
+### Modifier Combinations {#modifier-combinations}
+
+You can use each modifier separately or combine them.
+
+**Examples:**
+
+Using the same modifier multiple times.
+
+``` sql
+SELECT COLUMNS('[jk]') APPLY(toString) APPLY(length) APPLY(max) from columns_transformers;
+```
+
+```
+┌─max(length(toString(j)))─┬─max(length(toString(k)))─┐
+│                        2 │                        3 │
+└──────────────────────────┴──────────────────────────┘
+```
+
+Using multiple modifiers in a single query.
+
+``` sql
+SELECT * REPLACE(i + 1 AS i) EXCEPT (j) APPLY(sum) from columns_transformers;
+```
+
+```
+┌─sum(plus(i, 1))─┬─sum(k)─┐
+│             222 │    347 │
+└─────────────────┴────────┘
+```
+
+## SETTINGS in SELECT Query {#settings-in-select}
+
+You can specify the necessary settings right in the `SELECT` query. The setting value is applied only to this query and is reset to default or previous value after the query is executed. 
+
+Other ways to make settings see [here](../../../operations/settings/index.md). 
+
+**Example**
+
+``` sql
+SELECT * FROM some_table SETTINGS optimize_read_in_order=1, cast_keep_nullable=1;
+```

+
+# OFFSET FETCH Clause {#offset-fetch}
+
+`OFFSET` and `FETCH` allow you to retrieve data by portions. They specify a row block which you want to get by a single query.
+
+``` sql
+OFFSET offset_row_count {ROW | ROWS}] [FETCH {FIRST | NEXT} fetch_row_count {ROW | ROWS} {ONLY | WITH TIES}]
+```
+
+The `offset_row_count` or `fetch_row_count` value can be a number or a literal constant. You can omit `fetch_row_count`; by default, it equals to 1.
+
+`OFFSET` specifies the number of rows to skip before starting to return rows from the query result set.
+
+The `FETCH` specifies the maximum number of rows that can be in the result of a query.
+
+The `ONLY` option is used to return rows that immediately follow the rows omitted by the `OFFSET`. In this case the `FETCH` is an alternative to the [LIMIT](../../../sql-reference/statements/select/limit.md) clause. For example, the following query
+
+``` sql
+SELECT * FROM test_fetch ORDER BY a OFFSET 1 ROW FETCH FIRST 3 ROWS ONLY;
+```
+
+is identical to the query
+
+``` sql
+SELECT * FROM test_fetch ORDER BY a LIMIT 3 OFFSET 1;
+```
+
+The `WITH TIES` option is used to return any additional rows that tie for the last place in the result set according to the `ORDER BY` clause. For example, if `fetch_row_count` is set to 5 but two additional rows match the values of the `ORDER BY` columns in the fifth row, the result set will contain seven rows.
+
+!!! note "Note"
+    According to the standard, the `OFFSET` clause must come before the `FETCH` clause if both are present.
+    
+!!! note "Note"
+    The real offset can also depend on the [offset](../../../operations/settings/settings.md#offset) setting.

Позже ненужные колонки могут быть удалены из блока, но не модифицированы. Это удобно для устранения общих подвыражений.

 2. Реализацию форматов данных. Например, при выводе данных в терминал в формате `Pretty`, вы создаете выходной поток блоков, который форматирует поступающие в него блоки.
 3. Трансформацию данных. Допустим, у вас есть `IBlockInputStream` и вы хотите создать отфильтрованный поток. Вы создаете `FilterBlockInputStream` и инициализируете его вашим потоком. Затем вы тянете (pull) блоки из `FilterBlockInputStream`, а он тянет блоки исходного потока, фильтрует их и возвращает отфильтрованные блоки вам. Таким образом построены конвейеры выполнения запросов.
 
-Имеются и более сложные трансформации. Например, когда вы тянете блоки из `AggregatingBlockInputStream`, он считывает все данные из своего источника, агрегирует их, и возвращает поток агрегированных данных вам. Другой пример: конструктор `UnionBlockInputStream` принимает множество источников входных данных и число потоков. Такой `Stream` работает в несколько потоков и читает данные источников параллельно.

 > Потоки блоков используют «втягивающий» (pull) подход к управлению потоком выполнения: когда вы вытягиваете блок из первого потока, он, следовательно, вытягивает необходимые блоки из вложенных потоков, так и работает весь конвейер выполнения. Ни «pull» ни «push» не имеют явного преимущества, потому что поток управления неявный, и это ограничивает в реализации различных функций, таких как одновременное выполнение нескольких запросов (слияние нескольких конвейеров вместе). Это ограничение можно преодолеть с помощью сопрограмм (coroutines) или просто запуском дополнительных потоков, которые ждут друг друга. У нас может быть больше возможностей, если мы сделаем поток управления явным: если мы локализуем логику для передачи данных из одной расчетной единицы в другую вне этих расчетных единиц.

 ## Интерпретаторы {#interpreters}

 Интерпретаторы отвечают за создание конвейера выполнения запроса из `AST`. Есть простые интерпретаторы, такие как `InterpreterExistsQuery` и `InterpreterDropQuery` или более сложный `InterpreterSelectQuery`. Конвейер выполнения запроса представляет собой комбинацию входных и выходных потоков блоков. Например, результатом интерпретации `SELECT` запроса является `IBlockInputStream` для чтения результирующего набора данных; результат интерпретации `INSERT` запроса - это `IBlockOutputStream`, для записи данных, предназначенных для вставки; результат интерпретации `INSERT SELECT` запроса - это `IBlockInputStream`, который возвращает пустой результирующий набор при первом чтении, но копирует данные из `SELECT` к `INSERT`.
- 
+
 `InterpreterSelectQuery` использует `ExpressionAnalyzer` и `ExpressionActions` механизмы для анализа запросов и преобразований. Именно здесь выполняется большинство оптимизаций запросов на основе правил. `ExpressionAnalyzer` написан довольно грязно и должен быть переписан: различные преобразования запросов и оптимизации должны быть извлечены в отдельные классы, чтобы позволить модульные преобразования или запросы.

 Сервера в кластере в основном независимы. Вы можете создать `Распределенную` (`Distributed`) таблицу на одном или всех серверах в кластере. Такая таблица сама по себе не хранит данные - она только предоставляет возможность "просмотра" всех локальных таблиц на нескольких узлах кластера. При выполнении `SELECT` распределенная таблица переписывает запрос, выбирает удаленные узлы в соответствии с настройками балансировки нагрузки и отправляет им запрос. Распределенная таблица просит удаленные сервера обработать запрос до той стадии, когда промежуточные результаты с разных серверов могут быть объединены. Затем он получает промежуточные результаты и объединяет их. Распределенная таблица пытается возложить как можно больше работы на удаленные серверы и сократить объем промежуточных данных, передаваемых по сети.

 Репликация использует асинхронную multi-master схему. Вы можете вставить данные в любую реплику, которая имеет открытую сессию в `ZooKeeper`, и данные реплицируются на все другие реплики асинхронно. Поскольку ClickHouse не поддерживает UPDATE, репликация исключает конфликты (conflict-free replication). Поскольку подтверждение вставок кворумом не реализовано, только что вставленные данные могут быть потеряны в случае сбоя одного узла.

Каждая реплика копирует журнал репликации в свою очередь, а затем выполняет действия из очереди. Например, при вставке в журнале создается действие «получить часть» (get the part), и каждая реплика загружает эту часть. Слияния координируются между репликами, чтобы получить идентичные до байта результаты. Все части объединяются одинаково на всех репликах. Одна из реплик-лидеров инициирует новое слияние кусков первой и записывает действия «слияния частей» в журнал. Несколько реплик (или все) могут быть лидерами одновременно.

Крупные объединенные части отправляются по сети только в случае значительной задержки репликации.

+## Особенности и рекомендации {#specifics-and-recommendations}
+
+### UUID {#table-uuid}
+
+Каждая таблица в базе данных `Atomic` имеет уникальный [UUID](../../sql-reference/data-types/uuid.md) и хранит данные в папке `/clickhouse_path/store/xxx/xxxyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy/`, где `xxxyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy` - это UUID таблицы.
+Обычно UUID генерируется автоматически, но пользователь также может явно указать UUID в момент создания таблицы (однако это не рекомендуется). Для отображения UUID в запросе `SHOW CREATE` вы можете использовать настройку [show_table_uuid_in_table_create_query_if_not_nil](../../operations/settings/settings.md#show_table_uuid_in_table_create_query_if_not_nil). Результат выполнения в таком случае будет иметь вид:
+
+```sql
+CREATE TABLE name UUID '28f1c61c-2970-457a-bffe-454156ddcfef' (n UInt64) ENGINE = ...;
+```
+### RENAME TABLE {#rename-table}
+
+Запросы `RENAME` выполняются без изменения UUID и перемещения табличных данных. Эти запросы не ожидают завершения использующих таблицу запросов и будут выполнены мгновенно. 
+
+### DROP/DETACH TABLE {#drop-detach-table}
+
+При выполнении запроса `DROP TABLE` никакие данные не удаляются. Таблица помечается как удаленная, метаданные перемещаются в папку `/clickhouse_path/metadata_dropped/` и база данных уведомляет фоновый поток. Задержка перед окончательным удалением данных задается настройкой [database_atomic_delay_before_drop_table_sec](../../operations/server-configuration-parameters/settings.md#database_atomic_delay_before_drop_table_sec).
+Вы можете задать синхронный режим, определяя модификатор `SYNC`. Используйте для этого настройку [database_atomic_wait_for_drop_and_detach_synchronously](../../operations/settings/settings.md#database_atomic_wait_for_drop_and_detach_synchronously). В этом случае запрос `DROP` ждет завершения `SELECT`, `INSERT` и других запросов, которые используют таблицу. Таблица будет фактически удалена, когда она не будет использоваться.
+
+### EXCHANGE TABLES {#exchange-tables}
+
+Запрос `EXCHANGE` меняет местами две таблицы атомарно. Вместо неатомарной операции:
+
+```sql
+RENAME TABLE new_table TO tmp, old_table TO new_table, tmp TO old_table;
+```
+вы можете использовать один атомарный запрос:
+
+``` sql
+EXCHANGE TABLES new_table AND old_table;
+```
+
+### ReplicatedMergeTree in Atomic Database {#replicatedmergetree-in-atomic-database}
+
+Для таблиц [ReplicatedMergeTree](../table-engines/mergetree-family/replication.md#table_engines-replication) рекомендуется не указывать параметры движка - путь в ZooKeeper и имя реплики. В этом случае будут использоваться параметры конфигурации: [default_replica_path](../../operations/server-configuration-parameters/settings.md#default_replica_path) и [default_replica_name](../../operations/server-configuration-parameters/settings.md#default_replica_name). Если вы хотите определить параметры движка явно, рекомендуется использовать макрос {uuid}. Это удобно, так как автоматически генерируются уникальные пути для каждой таблицы в ZooKeeper.

+## Примеры использования {#examples-of-use}
+
+Обмен данными между БД ClickHouse и сервером PostgreSQL:
+
+``` sql
+CREATE DATABASE test_database 
+ENGINE = PostgreSQL('postgres1:5432', 'test_database', 'postgres', 'mysecretpassword', 1);
+```
+
+``` sql
+SHOW DATABASES;
+```
+
+``` text
+┌─name──────────┐
+│ default       │
+│ test_database │
+│ system        │
+└───────────────┘
+```
+
+``` sql
+SHOW TABLES FROM test_database;
+```
+
+``` text
+┌─name───────┐
+│ test_table │
+└────────────┘
+```
+
+Чтение данных из таблицы PostgreSQL:
+
+``` sql
+SELECT * FROM test_database.test_table;
+```
+
+``` text
+┌─id─┬─value─┐
+│  1 │     2 │
+└────┴───────┘
+```
+
+Запись данных в таблицу PostgreSQL:
+
+``` sql
+INSERT INTO test_database.test_table VALUES (3,4);
+SELECT * FROM test_database.test_table;
+```
+
+``` text
+┌─int_id─┬─value─┐
+│      1 │     2 │
+│      3 │     4 │
+└────────┴───────┘
+```
+
+Пусть структура таблицы была изменена в PostgreSQL: 
+
+``` sql
+postgre> ALTER TABLE test_table ADD COLUMN data Text
+```
+
+Поскольку при создании БД параметр `use_table_cache` был установлен в значение `1`, структура таблицы в ClickHouse была кеширована и поэтому не изменилась:
+
+``` sql
+DESCRIBE TABLE test_database.test_table;
+```
+``` text
+┌─name───┬─type──────────────┐
+│ id     │ Nullable(Integer) │
+│ value  │ Nullable(Integer) │
+└────────┴───────────────────┘
+```
+
+После того как таблицу «отцепили» и затем снова «прицепили», структура обновилась:
+
+``` sql
+DETACH TABLE test_database.test_table;
+ATTACH TABLE test_database.test_table;
+DESCRIBE TABLE test_database.test_table;
+```
+``` text
+┌─name───┬─type──────────────┐
+│ id     │ Nullable(Integer) │
+│ value  │ Nullable(Integer) │
+│ data   │ Nullable(String)  │
+└────────┴───────────────────┘
+```

 Чтобы получить данные из виртуального столбца, необходимо указать его название в запросе `SELECT`. `SELECT *` не отображает данные из виртуальных столбцов.
 
 При создании таблицы со столбцом, имя которого совпадает с именем одного из виртуальных столбцов таблицы, виртуальный столбец становится недоступным. Не делайте так. Чтобы помочь избежать конфликтов, имена виртуальных столбцов обычно предваряются подчеркиванием.

+-   Имена столбцов должны быть такими же, как в исходной таблице PostgreSQL, но вы можете использовать только некоторые из этих столбцов и в любом порядке.

 -   Настройка `external_table_functions_use_nulls` определяет как обрабатывать Nullable столбцы. По умолчанию 1, если 0 - табличная функция не будет делать nullable столбцы и будет вместо null выставлять значения по умолчанию для скалярного типа. Это также применимо для null значений внутри массивов.

 -   `database` — Имя базы данных на сервере PostgreSQL.
-
 -   `table` — Имя таблицы.

 PostgreSQL массивы конвертируются в массивы ClickHouse.
-Будьте осторожны в PostgreSQL массивы созданные как type_name[], являются многомерными и могут содержать в себе разное количество измерений в разных строках одной таблицы, внутри ClickHouse допустипы только многомерные массивы с одинаковым кол-вом измерений во всех строках таблицы.

 В этом примере задано партиционирование по типам событий, произошедших в течение текущей недели.
 
+По умолчанию, ключ партиционирования с плавающей запятой не поддерживается. Чтобы использовать его, включите настройку [allow_floating_point_partition_key](../../../operations/settings/merge-tree-settings.md#allow_floating_point_partition_key).
+
 Каждая партиция состоит из отдельных фрагментов или так называемых *кусков данных*. Каждый кусок отсортирован по первичному ключу. При вставке данных в таблицу каждая отдельная запись сохраняется в виде отдельного куска. Через некоторое время после вставки (обычно до 10 минут), ClickHouse выполняет в фоновом режиме слияние данных — в результате куски для одной и той же партиции будут объединены в более крупный кусок.

 Репликация асинхронная, мульти-мастер. Запросы `INSERT` и `ALTER` можно направлять на любой доступный сервер. Данные вставятся на сервер, где выполнен запрос, а затем скопируются на остальные серверы. В связи с асинхронностью, только что вставленные данные появляются на остальных репликах с небольшой задержкой. Если часть реплик недоступна, данные на них запишутся тогда, когда они станут доступны. Если реплика доступна, то задержка составляет столько времени, сколько требуется для передачи блока сжатых данных по сети. Количество потоков для выполнения фоновых задач можно задать с помощью настройки [background_schedule_pool_size](../../../operations/settings/settings.md#background_schedule_pool_size).
 
+Движок `ReplicatedMergeTree` использует отдельный пул потоков для скачивания кусков данных. Размер пула ограничен настройкой [background_fetches_pool_size](../../../operations/settings/settings.md#background_fetches_pool_size), которую можно указать при перезапуске сервера. 
+
 По умолчанию, запрос INSERT ждёт подтверждения записи только от одной реплики. Если данные были успешно записаны только на одну реплику, и сервер с этой репликой перестал существовать, то записанные данные будут потеряны. Вы можете включить подтверждение записи от нескольких реплик, используя настройку `insert_quorum`.
 
 Каждый блок данных записывается атомарно. Запрос INSERT разбивается на блоки данных размером до `max_insert_block_size = 1048576` строк. То есть, если в запросе `INSERT` менее 1048576 строк, то он делается атомарно.

+# Вышки сотовой связи {#cell-towers}
+
+Источник этого набора данных (dataset) - самая большая в мире открытая база данных о сотовых вышках - [OpenCellid](https://www.opencellid.org/). К 2021-му году здесь накопилось более, чем 40 миллионов записей о сотовых вышках (GSM, LTE, UMTS, и т.д.) по всему миру с их географическими координатами и метаданными (код страны, сети, и т.д.).
+
+OpenCelliD Project имеет лицензию Creative Commons Attribution-ShareAlike 4.0 International License, и мы распространяем снэпшот набора данных по условиям этой же лицензии. После авторизации можно загрузить последнюю версию набора данных.
+
+## Как получить набор данных {#get-the-dataset}
+
+1. Загрузите снэпшот набора данных за февраль 2021 [отсюда](https://datasets.clickhouse.tech/cell_towers.csv.xz) (729 MB).
+
+2. Если нужно, проверьте полноту и целостность при помощи команды:
+
+```
+md5sum cell_towers.csv.xz
+8cf986f4a0d9f12c6f384a0e9192c908  cell_towers.csv.xz
+```
+
+3. Распакуйте набор данных при помощи команды:
+
+```
+xz -d cell_towers.csv.xz
+```
+
+4. Создайте таблицу:
+
+```
+CREATE TABLE cell_towers
+(
+    radio Enum8('' = 0, 'CDMA' = 1, 'GSM' = 2, 'LTE' = 3, 'NR' = 4, 'UMTS' = 5),
+    mcc UInt16,
+    net UInt16,
+    area UInt16,
+    cell UInt64,
+    unit Int16,
+    lon Float64,
+    lat Float64,
+    range UInt32,
+    samples UInt32,
+    changeable UInt8,
+    created DateTime,
+    updated DateTime,
+    averageSignal UInt8
+)
+ENGINE = MergeTree ORDER BY (radio, mcc, net, created);
+```
+
+5. Вставьте данные:
+```
+clickhouse-client --query "INSERT INTO cell_towers FORMAT CSVWithNames" < cell_towers.csv
+```
+

 Сервер следит за изменениями конфигурационных файлов, а также файлов и ZooKeeper-узлов, которые были использованы при выполнении подстановок и переопределений, и перезагружает настройки пользователей и кластеров на лету. То есть, можно изменять кластера, пользователей и их настройки без перезапуска сервера.
 
+## Примеры записи конфигурации на YAML {#example}
+
+Здесь можно рассмотреть пример реальной конфигурации записанной на YAML: [config.yaml.example](https://github.com/ClickHouse/ClickHouse/blob/master/programs/server/config.yaml.example).
+
+Между стандартами XML и YAML имеются различия, поэтому в этом разделе будут перечислены некоторые подсказки для написания конфигурации на YMAL.
+
+Для записи обычной пары ключ-значение следует использовать Scalar:
+``` yaml
+key: value
+```
+
+Для создания тега, содержащего подтеги следует использовать Map:
+``` yaml
+map_key:
+  key1: val1
+  key2: val2
+  key3: val3
+```
+
+Для создания списка значений или подтегов, расположенных по определенному ключу, следует использовать Sequence:
+``` yaml
+seq_key:
+  - val1
+  - val2
+  - key1: val3
+  - map:
+      key2: val4
+      key3: val5
+```
+
+В случае, усли необходимо объявить тег, аналогичный XML-атрибуту, необходимо задать скаляр, имеющий ключ с префиксом @ и заключенный в кавычки:
+
+``` yaml
+map:
+  "@attr1": value1
+  "@attr2": value2
+  key: 123
+```
+
+Из такой Map мы получим после конвертации:
+
+``` xml
+<map attr1="value1" attr2="value2">
+    <key>123</key>
+</map>
+```
+
+Помимо Map, можно задавать атрибуты для Sequence:
+
+``` yaml
+seq:
+  - "@attr1": value1
+  - "@attr2": value2
+  - 123
+  - abc
+```
+
+Таким образом получая аналог следующей записи на XML:
+
+``` xml
+<seq attr1="value1" attr2="value2">123</seq>
+<seq attr1="value1" attr2="value2">abc</seq>
+```

+## check_query_single_value_result {#check_query_single_value_result}
+
+Определяет уровень детализации результата для запросов [CHECK TABLE](../../sql-reference/statements/check-table.md#checking-mergetree-tables) для таблиц семейства `MergeTree`.
+
+Возможные значения:
+
+-   0 — запрос возвращает статус каждого куска данных таблицы.
+-   1 — запрос возвращает статус таблицы в целом.
+
+Значение по умолчанию: `0`.
+
+## prefer_column_name_to_alias {#prefer-column-name-to-alias}
+
+Включает или отключает замену названий столбцов на псевдонимы (alias) в выражениях и секциях запросов, см. [Примечания по использованию синонимов](../../sql-reference/syntax.md#syntax-expression_aliases). Включите эту настройку, чтобы синтаксис псевдонимов в ClickHouse был более совместим с большинством других СУБД.
+
+Возможные значения:
+
+- 0 — псевдоним подставляется вместо имени столбца.
+- 1 — псевдоним не подставляется вместо имени столбца.
+
+Значение по умолчанию: `0`.
+
+**Пример**
+
+Какие изменения привносит включение и выключение настройки: 
+

----
-
-# Советы по эксплуатации {#sovety-po-ekspluatatsii}
-
-## CPU Scaling Governor {#cpu-scaling-governor}
-
-Всегда используйте `performance` scaling governor. `ondemand` scaling governor работает намного хуже при постоянно высоком спросе.
-
-``` bash
-$ echo 'performance' | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
-```
-
-## Ограничение CPU {#ogranichenie-cpu}
-
-Процессоры могут перегреваться. С помощью `dmesg` можно увидеть, если тактовая частота процессора была ограничена из-за перегрева.
-Также ограничение может устанавливаться снаружи на уровне дата-центра. С помощью `turbostat` можно за этим наблюдать под нагрузкой.
-
-## Оперативная память {#operativnaia-pamiat}
-
-Для небольших объёмов данных (до ~200 Гб в сжатом виде) лучше всего использовать столько памяти не меньше, чем объём данных.
-Для больших объёмов данных, при выполнении интерактивных (онлайн) запросов, стоит использовать разумный объём оперативной памяти (128 Гб или более) для того, чтобы горячее подмножество данных поместилось в кеше страниц.
-Даже для объёмов данных в ~50 Тб на сервер, использование 128 Гб оперативной памяти намного лучше для производительности выполнения запросов, чем 64 Гб.
-
-Не выключайте overcommit. Значение `cat /proc/sys/vm/overcommit_memory` должно быть 0 or 1. Выполните:
-
-``` bash
-$ echo 0 | sudo tee /proc/sys/vm/overcommit_memory
-```
-
-## Huge Pages {#huge-pages}
-
-Механизм прозрачных huge pages нужно отключить. Он мешает работе аллокаторов памяти, что приводит к значительной деградации производительности.
-
-``` bash
-$ echo 'madvise' | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
-```
-
-С помощью `perf top` можно наблюдать за временем, проведенном в ядре операционной системы для управления памятью.
-Постоянные huge pages так же не нужно аллоцировать.
-
-## Подсистема хранения {#podsistema-khraneniia}
-
-Если ваш бюджет позволяет использовать SSD, используйте SSD.
-В противном случае используйте HDD. SATA HDDs 7200 RPM подойдут.
-
-Предпочитайте много серверов с локальными жесткими дисками вместо меньшего числа серверов с подключенными дисковыми полками.
-Но для хранения архивов с редкими запросами полки всё же подходят.
-
-## RAID {#raid}
-
-При использовании HDD можно объединить их RAID-10, RAID-5, RAID-6 или RAID-50.
-Лучше использовать программный RAID в Linux (`mdadm`). Лучше не использовать LVM.
-При создании RAID-10, нужно выбрать `far` расположение.
-Если бюджет позволяет, лучше выбрать RAID-10.
-
-На более чем 4 дисках вместо RAID-5 нужно использовать RAID-6 (предпочтительнее) или RAID-50.
-При использовании RAID-5, RAID-6 или RAID-50, нужно всегда увеличивать stripe_cache_size, так как значение по умолчанию выбрано не самым удачным образом.
-
-``` bash
-$ echo 4096 | sudo tee /sys/block/md2/md/stripe_cache_size
-```
-
-Точное число стоит вычислять из числа устройств и размер блока по формуле: `2 * num_devices * chunk_size_in_bytes / 4096`.
-
-Размер блока в 1024 Кб подходит для всех конфигураций RAID.
-Никогда не указывайте слишком маленький или слишком большой размер блока.
-
-На SSD можно использовать RAID-0.
-Вне зависимости от использования RAID, всегда используйте репликацию для безопасности данных.
-
-Включите NCQ с длинной очередью. Для HDD стоит выбрать планировщик CFQ, а для SSD — noop. Не стоит уменьшать настройку readahead.
-На HDD стоит включать кеш записи.
-
-## Файловая система {#failovaia-sistema}
-
-Ext4 самый проверенный вариант. Укажите опции монтирования `noatime,nobarrier`.
-XFS также подходит, но не так тщательно протестирована в сочетании с ClickHouse.
-Большинство других файловых систем также должны нормально работать. Файловые системы с отложенной аллокацией работают лучше.
-
-## Ядро Linux {#iadro-linux}
-
-Не используйте слишком старое ядро Linux.
-
-## Сеть {#set}
-
-При использовании IPv6, стоит увеличить размер кеша маршрутов.
-Ядра Linux до 3.2 имели массу проблем в реализации IPv6.
-
-Предпочитайте как минимум 10 Гбит сеть. 1 Гбит также будет работать, но намного хуже для починки реплик с десятками терабайт данных или для обработки распределенных запросов с большим объёмом промежуточных данных.
-
-## ZooKeeper {#zookeeper}
-
-Вероятно вы уже используете ZooKeeper для других целей. Можно использовать ту же инсталляцию ZooKeeper, если она не сильно перегружена.
-
-Лучше использовать свежую версию ZooKeeper, как минимум 3.4.9. Версия в стабильных дистрибутивах Linux может быть устаревшей.
-
-Никогда не используете написанные вручную скрипты для переноса данных между разными ZooKeeper кластерами, потому что результат будет некорректный для sequential нод. Никогда не используйте утилиту «zkcopy», по той же причине: https://github.com/ksprojects/zkcopy/issues/15
-
-Если вы хотите разделить существующий ZooKeeper кластер на два, правильный способ - увеличить количество его реплик, а затем переконфигурировать его как два независимых кластера.
-
-Не запускайте ZooKeeper на тех же серверах, что и ClickHouse. Потому что ZooKeeper очень чувствителен к задержкам, а ClickHouse может использовать все доступные системные ресурсы.
-
-С настройками по умолчанию, ZooKeeper является бомбой замедленного действия:
-
-> Сервер ZooKeeper не будет удалять файлы со старыми снепшоты и логами при использовании конфигурации по умолчанию (см. autopurge), это является ответственностью оператора.
-
-Эту бомбу нужно обезвредить.
-
-Далее описана конфигурация ZooKeeper (3.5.1), используемая в боевом окружении Яндекс.Метрики на момент 20 мая 2017 года:

+
+Позволяет форматировать входящие запросы.
+
+Ключи:
+
+- `--help` или`-h` — выводит описание ключей.
+- `--hilite` — добавляет подсветку синтаксиса с экранированием символов.
+- `--oneline` — форматирование в одну строку.
+- `--quiet` или `-q` — проверяет синтаксис без вывода результата.
+- `--multiquery` or `-n` — поддерживает несколько запросов в одной строке.
+- `--obfuscate` — обфусцирует вместо форматирования.
+- `--seed <строка>` — задает строку, которая определяет результат обфускации.
+- `--backslash` — добавляет обратный слеш в конце каждой строки отформатированного запроса. Удобно использовать если многострочный запрос скопирован из интернета или другого источника и его нужно выполнить из командной строки.
+
+## Примеры {#examples} 
+
+1. Подсветка синтаксиса и форматирование в одну строку:
+
+```bash
+$ clickhouse-format --oneline --hilite <<< "SELECT sum(number) FROM numbers(5);"
+```
+
+Результат:
+
+```sql
+SELECT sum(number) FROM numbers(5)
+```
+
+2. Несколько запросов в одной строке: 
+
+```bash
+$ clickhouse-format -n <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
+```
+    
+Результат:
+
+```text
+SELECT *
+FROM
+(
+    SELECT 1 AS x
+    UNION ALL
+    SELECT 1
+    UNION DISTINCT
+    SELECT 3
+)
+;
+```
+
+3. Обфускация:
+
+```bash
+$ clickhouse-format --seed Hello --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
+```
+
+Результат:
+
+```text
+SELECT treasury_mammoth_hazelnut BETWEEN nutmeg AND span, CASE WHEN chive >= 116 THEN switching ELSE ANYTHING END;
+```
+   
+Тот же запрос с другой инициализацией обфускатора:
+
+```bash
+$ clickhouse-format --seed World --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
+```
+    
+Результат:
+
+```text
+SELECT horse_tape_summer BETWEEN folklore AND moccasins, CASE WHEN intestine >= 116 THEN nonconformist ELSE FORESTRY END;
+```
+
+4. Добавление обратного слеша:
+
+```bash
+$ clickhouse-format --backslash <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
+```
+
+Результат:
+
+```text
+SELECT * \
+FROM  \
+( \
+    SELECT 1 AS x \
+    UNION ALL \
+    SELECT 1 \
+    UNION DISTINCT \
+    SELECT 3 \
+)

+# clickhouse-odbc-bridge
+
+Simple HTTP-server which works like a proxy for ODBC driver. The main motivation
+was possible segfaults or another faults in ODBC implementations, which can
+crash whole clickhouse-server process.
+
+This tool works via HTTP, not via pipes, shared memory, or TCP because:
+- It's simpler to implement
+- It's simpler to debug
+- jdbc-bridge can be implemented in the same way
+
+## Usage
+
+`clickhouse-server` use this tool inside odbc table function and StorageODBC.
+However it can be used as standalone tool from command line with the following
+parameters in POST-request URL:
+- `connection_string` -- ODBC connection string.
+- `columns` -- columns in ClickHouse NamesAndTypesList format, name in backticks,
+  type as string. Name and type are space separated, rows separated with
+  newline.
+- `max_block_size` -- optional parameter, sets maximum size of single block.
+Query is send in post body. Response is returned in RowBinary format.
+
+## Example:
+
+```bash
+$ clickhouse-odbc-bridge --http-port 9018 --daemon
+
+$ curl -d "query=SELECT PageID, ImpID, AdType FROM Keys ORDER BY PageID, ImpID" --data-urlencode "connection_string=DSN=ClickHouse;DATABASE=stat" --data-urlencode "columns=columns format version: 1
+3 columns:
+\`PageID\` String
+\`ImpID\` String
+\`AdType\` String
+"  "http://localhost:9018/" > result.txt
+
+$ cat result.txt # Result in RowBinary format

+
+Суммирует разницу между последовательными строками. Если разница отрицательна — она будет проигнорирована. 
+
+Эта функция предназначена в первую очередь для [материализованных представлений](../../../sql-reference/statements/create/view.md#materialized), упорядоченных по некоторому временному бакету согласно timestamp, например, по бакету `toStartOfMinute`. Поскольку строки в таком материализованном представлении будут иметь одинаковый timestamp, невозможно объединить их в "правом" порядке. Функция отслеживает `timestamp` наблюдаемых значений, поэтому возможно правильно упорядочить состояния во время слияния.
+
+Чтобы вычислить разницу между упорядоченными последовательными строками, вы можете использовать функцию [deltaSum](../../../sql-reference/aggregate-functions/reference/deltasum.md#agg_functions-deltasum) вместо функции `deltaSumTimestamp`.

 а затем повторного выполнения `f` к результатам: `f(S1 UNION ALL S2) = f(f(S1) UNION ALL f(S2))`. Это свойство гарантирует, что результатов частичной агрегации достаточно для вычисления комбинированной, поэтому хранить и обрабатывать какие-либо дополнительные данные не требуется.

+Возвращает все данные из диапазона, в который попадают данные, соответствующие указанному выражению.
+Переданное выражение не будет вычислено. Выбор диапазона производится по индексу.
+Индекс в ClickHouse разреженный, при чтении диапазона в ответ попадают «лишние» соседние данные.
+
+**Синтаксис**
+
+```sql
+SELECT * FROM table WHERE indexHint(<expression>)
+```
+
+**Возвращаемое значение**
+
+Возвращает диапазон индекса, в котором выполняется заданное условие.
+
+Тип: [Uint8](https://clickhouse.yandex/docs/ru/data_types/int_uint/#diapazony-uint).
+
+**Пример**
+
+Рассмотрим пример с использованием тестовых данных таблицы [ontime](../../getting-started/example-datasets/ontime.md).
+
+Исходная таблица:
+
+```sql
+SELECT count() FROM ontime
+```
+
+```text
+┌─count()─┐
+│ 4276457 │
+└─────────┘
+```
+
+В таблице есть индексы по полям `(FlightDate, (Year, FlightDate))`.
+
+Выполним выборку по дате, где индекс не используется.
+
+Запрос:
+
+```sql
+SELECT FlightDate AS k, count() FROM ontime GROUP BY k ORDER BY k
+```
+
+ClickHouse обработал всю таблицу (`Processed 4.28 million rows`).
+
+Результат:
+
+```text
+┌──────────k─┬─count()─┐
+│ 2017-01-01 │   13970 │
+│ 2017-01-02 │   15882 │

+│ 2017-09-30 │   12520 │
+└────────────┴─────────┘
+```
+
+Для подключения индекса выбираем конкретную дату.
+
+Запрос:
+
+```sql
+SELECT FlightDate AS k, count() FROM ontime WHERE k = '2017-09-15' GROUP BY k ORDER BY k
+```
+
+При использовании индекса ClickHouse обработал значительно меньшее количество строк (`Processed 32.74 thousand rows`).
+
+Результат:
+
+```text

+    count()
+FROM ontime
+WHERE indexHint(k = '2017-09-15')

+```
+
+ClickHouse применил индекс по аналогии с примером выше (`Processed 32.74 thousand rows`).

+## extractTextFromHTML {#extracttextfromhtml}
+
+Функция для извлечения текста из HTML или XHTML.
+Она не соответствует всем HTML, XML или XHTML стандартам на 100%, но ее реализация достаточно точная и быстрая. Правила обработки следующие:
+
+1. Комментарии удаляются. Пример: `<!-- test -->`. Комментарий должен оканчиваться символами `-->`. Вложенные комментарии недопустимы.
+Примечание: конструкции наподобие `<!-->` и `<!--->` не являются допустимыми комментариями в HTML, но они будут удалены согласно другим правилам.
+2. Содержимое CDATA вставляется дословно. Примечание: формат CDATA специфичен для XML/XHTML. Но он обрабатывается всегда по принципу "наилучшего возможного результата".
+3. Элементы `script` и `style` удаляются вместе со всем содержимым. Примечание: предполагается, что закрывающий тег не может появиться внутри содержимого. Например, в JS строковый литерал должен быть экранирован как `"<\/script>"`.
+Примечание: комментарии и CDATA возможны внутри `script` или `style` - тогда закрывающие теги не ищутся внутри CDATA. Пример: `<script><![CDATA[</script>]]></script>`. Но они ищутся внутри комментариев. Иногда возникают сложные случаи: `<script>var x = "<!--"; </script> var y = "-->"; alert(x + y);</script>`
+Примечание: `script` и `style` могут быть названиями пространств имен XML - тогда они не обрабатываются как обычные элементы `script` или `style`. Пример: `<script:a>Hello</script:a>`.
+Примечание: пробелы возможны после имени закрывающего тега: `</script >`, но не перед ним: `< / script>`.
+4. Другие теги или элементы, подобные тегам, удаляются, а их внутреннее содержимое остается. Пример: `<a>.</a>`
+Примечание: ожидается, что такой HTML является недопустимым: `<a test=">"></a>`
+Примечание: функция также удаляет подобные тегам элементы: `<>`, `<!>`, и т. д.
+Примечание: если встречается тег без завершающего символа `>`, то удаляется этот тег и весь следующий за ним текст: `<hello `
+5. Мнемоники HTML и XML не декодируются. Они должны быть обработаны отдельной функцией.
+6. Пробелы в тексте удаляются и добавляются по следующим правилам:
+- Пробелы в начале и в конце извлеченного текста удаляются.
+- Несколько пробелов подряд заменяются одним пробелом.
+- Если текст разделен другими удаляемыми элементами и в этом месте нет пробела, он добавляется.
+- Это может привести к появлению неестественного написания, например: `Hello<b>world</b>`, `Hello<!-- -->world` — в HTML нет пробелов, но функция вставляет их. Также следует учитывать такие варианты написания: `Hello<p>world</p>`, `Hello<br>world`. Подобные результаты выполнения функции могут использоваться для анализа данных, например, для преобразования HTML-текста в набор используемых слов.
+7. Также обратите внимание, что правильная обработка пробелов требует поддержки `<pre></pre>` и свойств CSS `display` и `white-space`.
+
+**Синтаксис**
+
+``` sql
+extractTextFromHTML(x)
+```
+
+**Аргументы**
+
+-   `x` — текст для обработки. [String](../../sql-reference/data-types/string.md). 
+
+**Возвращаемое значение**
+
+-   Извлеченный текст.
+
+Тип: [String](../../sql-reference/data-types/string.md).
+
+**Пример**
+
+Первый пример содержит несколько тегов и комментарий. На этом примере также видно, как обрабатываются пробелы.
+Второй пример показывает обработку `CDATA` и тега `script`.
+В третьем примере текст выделяется из полного HTML ответа, полученного с помощью функции [url](../../sql-reference/table-functions/url.md).
+
+Запрос:
+
+``` sql
+SELECT extractTextFromHTML(' <p> A text <i>with</i><b>tags</b>. <!-- comments --> </p> ');
+SELECT extractTextFromHTML('<![CDATA[The content within <b>CDATA</b>]]> <script>alert("Script");</script>');
+SELECT extractTextFromHTML(html) FROM url('http://www.donothingfor2minutes.com/', RawBLOB, 'html String');

-
-С помощью данной секции можно создать политику разрешения или ограничения.
-
-Политика разрешения предоставляет доступ к строкам. Разрешительные политики, которые применяются к одной таблице, объединяются с помощью логического оператора `OR`. Политики являются разрешительными по умолчанию.
-
-Политика ограничения запрещает доступ к строкам. Ограничительные политики, которые применяются к одной таблице, объединяются логическим оператором `AND`.
-
-Ограничительные политики применяются к строкам, прошедшим фильтр разрешительной политики. Если вы не зададите разрешительные политики, пользователь не сможет обращаться ни к каким строкам из таблицы.
+Секция `USING` указывает условие для фильтрации строк. Пользователь может видеть строку, если это условие, вычисленное для строки, дает ненулевой результат.
 
 ## Секция TO {#create-row-policy-to}
 
-В секции `TO` вы можете перечислить как роли, так и пользователей. Например, `CREATE ROW POLICY ... TO accountant, john@localhost`.
+В секции `TO` перечисляются пользователи и роли, для которых должна действовать политика. Например, `CREATE ROW POLICY ... TO accountant, john@localhost`.
 
 Ключевым словом `ALL` обозначаются все пользователи, включая текущего. Ключевые слова `ALL EXCEPT` позволяют исключить пользователей из списка всех пользователей. Например, `CREATE ROW POLICY ... TO ALL EXCEPT accountant, john@localhost`
 
+!!! note "Note"
+    Если для таблицы не задано ни одной политики доступа к строкам, то любой пользователь может выполнить команду SELECT и получить все строки таблицы. Если определить хотя бы одну политику для таблицы, до доступ к строкам будет управляться этими политиками, причем для всех пользователей (даже для тех, для кого политики не определялись). Например, следующая политика
+
+    `CREATE ROW POLICY pol1 ON mydb.table1 USING b=1 TO mira, peter`
+
+    запретит пользователям `mira` и `peter` видеть строки с `b != 1`, и еще запретит всем остальным пользователям (например, пользователю `paul`) видеть какие-либо строки вообще из таблицы `mydb.table1`.
+    
+    Если это нежелательно, такое поведение можно исправить, определив дополнительную политику:
+
+    `CREATE ROW POLICY pol2 ON mydb.table1 USING 1 TO ALL EXCEPT mira, peter`
+
+## Секция AS {#create-row-policy-as}
+
+Может быть одновременно активно более одной политики для одной и той же таблицы и одного и того же пользователя. Поэтому нам нужен способ комбинировать политики.
+
+По умолчанию политики комбинируются с использованием логического оператора `OR`. Например, политики:
+
+``` sql
+CREATE ROW POLICY pol1 ON mydb.table1 USING b=1 TO mira, peter
+CREATE ROW POLICY pol2 ON mydb.table1 USING c=2 TO peter, antonio
+```
+
+разрешат пользователю с именем `peter` видеть строки, для которых будет верно `b=1` или `c=2`.
+
+Секция `AS` указывает, как политики должны комбинироваться с другими политиками. Политики могут быть или разрешительными (`PERMISSIVE`), или ограничительными (`RESTRICTIVE`). По умолчанию политики создаются разрешительными (`PERMISSIVE`); такие политики комбинируются с использованием логического оператора `OR`.
+
+Ограничительные (`RESTRICTIVE`) политики комбинируются с использованием логического оператора `AND`.
+
+Общая формула выглядит так:
+
+```
+строка_видима = (одна или больше permissive-политик дала ненулевой результат проверки условия) И
+                (все restrictive-политики дали ненулевой результат проверки условия)
+```
+
+Например, политики
+
+``` sql
+CREATE ROW POLICY pol1 ON mydb.table1 USING b=1 TO mira, peter
+CREATE ROW POLICY pol2 ON mydb.table1 USING c=2 AS RESTRICTIVE TO peter, antonio
+```
+
+разрешат пользователю с именем `peter` видеть только те строки, для которых будет одновременно `b=1` и `c=2`.

 ## Пользовательский хост
 
 Пользовательский хост — это хост, с которого можно установить соединение с сервером ClickHouse. Хост задается в секции `HOST` следующими способами:
 
-- `HOST IP 'ip_address_or_subnetwork'` — Пользователь может подключиться к серверу ClickHouse только с указанного IP-адреса или [подсети](https://ru.wikipedia.org/wiki/Подсеть). Примеры: `HOST IP '192.168.0.0/16'`, `HOST IP '2001:DB8::/32'`. При использовании в эксплуатации указывайте только элементы `HOST IP` (IP-адреса и маски подсети), так как использование `host` и `host_regexp` может привести к дополнительной задержке.
-- `HOST ANY` — Пользователь может подключиться с любого хоста. Используется по умолчанию.
-- `HOST LOCAL` — Пользователь может подключиться только локально.
-- `HOST NAME 'fqdn'` — Хост задается через FQDN. Например, `HOST NAME 'mysite.com'`.
-- `HOST NAME REGEXP 'regexp'` — Позволяет использовать регулярные выражения [pcre](http://www.pcre.org/), чтобы задать хосты. Например, `HOST NAME REGEXP '.*\.mysite\.com'`.
-- `HOST LIKE 'template'` — Позволяет использовать оператор [LIKE](../../functions/string-search-functions.md#function-like) для фильтрации хостов. Например, `HOST LIKE '%'` эквивалентен `HOST ANY`; `HOST LIKE '%.mysite.com'` разрешает подключение со всех хостов в домене `mysite.com`.
+-   `HOST IP 'ip_address_or_subnetwork'` — Пользователь может подключиться к серверу ClickHouse только с указанного IP-адреса или [подсети](https://ru.wikipedia.org/wiki/Подсеть). Примеры: `HOST IP '192.168.0.0/16'`, `HOST IP '2001:DB8::/32'`. При использовании в эксплуатации указывайте только элементы `HOST IP` (IP-адреса и маски подсети), так как использование `host` и `host_regexp` может привести к дополнительной задержке.
+-   `HOST ANY` — Пользователь может подключиться с любого хоста. Используется по умолчанию.
+-   `HOST LOCAL` — Пользователь может подключиться только локально.
+-   `HOST NAME 'fqdn'` — Хост задается через FQDN. Например, `HOST NAME 'mysite.com'`.
+-   `HOST NAME REGEXP 'regexp'` — Позволяет использовать регулярные выражения [pcre](http://www.pcre.org/), чтобы задать хосты. Например, `HOST NAME REGEXP '.*\.mysite\.com'`.
+-   `HOST LIKE 'template'` — Позволяет использовать оператор [LIKE](../../functions/string-search-functions.md#function-like) для фильтрации хостов. Например, `HOST LIKE '%'` эквивалентен `HOST ANY`; `HOST LIKE '%.mysite.com'` разрешает подключение со всех хостов в домене `mysite.com`.
 
 Также, чтобы задать хост, вы можете использовать `@` вместе с именем пользователя. Примеры:
 
-- `CREATE USER mira@'127.0.0.1'` — Эквивалентно `HOST IP`.
-- `CREATE USER mira@'localhost'` — Эквивалентно `HOST LOCAL`.
-- `CREATE USER mira@'192.168.%.%'` — Эквивалентно `HOST LIKE`.
+-   `CREATE USER mira@'127.0.0.1'` — Эквивалентно `HOST IP`.
+-   `CREATE USER mira@'localhost'` — Эквивалентно `HOST LOCAL`.
+-   `CREATE USER mira@'192.168.%.%'` — Эквивалентно `HOST LIKE`.
 
 !!! info "Внимание"
     ClickHouse трактует конструкцию `user_name@'address'` как имя пользователя целиком. То есть технически вы можете создать несколько пользователей с одинаковыми `user_name`, но разными частями конструкции после `@`, но лучше так не делать.
+	
+## Секция GRANTEES {#grantees}
 
+Указываются пользователи или роли, которым разрешено получать [привилегии](../../../sql-reference/statements/grant.md#grant-privileges) от создаваемого пользователя при условии, что этому пользователю также предоставлен весь необходимый доступ с использованием [GRANT OPTION](../../../sql-reference/statements/grant.md#grant-privigele-syntax). Параметры секции `GRANTEES`:
+
+-   `user` — указывается пользователь, которому разрешено получать привилегии от создаваемого пользователя.
+-   `role` — указывается роль, которой разрешено получать привилегии от создаваемого пользователя.
+-   `ANY` — любому пользователю или любой роли разрешено получать привилегии от создаваемого пользователя. Используется по умолчанию.
+-   `NONE` — никому не разрешено получать привилегии от создаваемого пользователя.
+
+Вы можете исключить любого пользователя или роль, используя выражение `EXCEPT`. Например, `CREATE USER user1 GRANTEES ANY EXCEPT user2`. Это означает, что если `user1` имеет привилегии, предоставленные с использованием `GRANT OPTION`, он сможет предоставить их любому, кроме `user2`.

+
+```sql
+EXPLAIN AST SELECT 1;
+```
+
+```sql

+## Выражение BY {#by-expression}
+
+Чтобы выполнить дедупликацию по произвольному набору столбцов, вы можете явно указать список столбцов или использовать любую комбинацию подстановки [`*`](../../sql-reference/statements/select/index.md#asterisk), выражений [`COLUMNS`](../../sql-reference/statements/select/index.md#columns-expression) и [`EXCEPT`](../../sql-reference/statements/select/index.md#except-modifier).
+
+ Список столбцов для дедупликации должен включать все столбцы, указанные в условиях сортировки (первичный ключ и ключ сортировки), а также в условиях партиционирования (ключ партиционирования).
+
+ !!! note "Примечание"
+    Обратите внимание, что символ подстановки `*` обрабатывается так же, как и в запросах `SELECT`: столбцы `MATERIALIZED` и `ALIAS` не включаются в результат.
+    Если указать пустой список или выражение, которое возвращает пустой список, или дедуплицировать столбец по псевдониму (`ALIAS`), то сервер вернет ошибку.
+
+
+**Примеры**
+
+Рассмотрим таблицу:
+
+``` sql
+CREATE TABLE example (
+    primary_key Int32,
+    secondary_key Int32,
+    value UInt32,
+    partition_key UInt32,

+    aliased_value UInt32 ALIAS 2,
+    PRIMARY KEY primary_key
+) ENGINE=MergeTree
+PARTITION BY partition_key;
+```
+
+Прежний способ дедупликации, когда учитываются все столбцы. Строка удаляется только в том случае, если все значения во всех столбцах равны соответствующим значениям в предыдущей строке.
+
+``` sql
+OPTIMIZE TABLE example FINAL DEDUPLICATE;
+```
+
+Дедупликация по всем столбцам, кроме `ALIAS` и `MATERIALIZED`: `primary_key`, `secondary_key`, `value`, `partition_key` и `materialized_value`.
+
+
+``` sql
+OPTIMIZE TABLE example FINAL DEDUPLICATE BY *;
+```
+
+Дедупликация по всем столбцам, кроме `ALIAS`, `MATERIALIZED` и `materialized_value`: столбцы `primary_key`, `secondary_key`, `value` и `partition_key`.

 Переименовывание таблицы является лёгкой операцией. Если вы указали после `TO` другую базу данных, то таблица будет перенесена в эту базу данных. При этом, директории с базами данных должны быть расположены в одной файловой системе (иначе возвращается ошибка). В случае переименования нескольких таблиц в одном запросе — это неатомарная операция,  может выполнится частично, запросы в других сессиях могут получить ошибку `Table ... doesn't exist...`.

+`OFFSET` и `FETCH` позволяют извлекать данные по частям. Они указывают строки, которые вы хотите получить в результате запроса.
+
+``` sql
+OFFSET offset_row_count {ROW | ROWS}] [FETCH {FIRST | NEXT} fetch_row_count {ROW | ROWS} {ONLY | WITH TIES}]
+```
+
+`offset_row_count` или `fetch_row_count` может быть числом или литеральной константой. Если вы не задаете `fetch_row_count` явно, используется значение по умолчанию, равное 1.
+
+`OFFSET` указывает количество строк, которые необходимо пропустить перед началом возврата строк из запроса.
+
+`FETCH` указывает максимальное количество строк, которые могут быть получены в результате запроса.
+
+Опция `ONLY` используется для возврата строк, которые следуют сразу же за строками, пропущенными секцией `OFFSET`. В этом случае `FETCH` — это альтернатива [LIMIT](../../../sql-reference/statements/select/limit.md). Например, следующий запрос
+
+``` sql
+SELECT * FROM test_fetch ORDER BY a OFFSET 1 ROW FETCH FIRST 3 ROWS ONLY;
+```
+
+идентичен запросу
+
+``` sql
+SELECT * FROM test_fetch ORDER BY a LIMIT 3 OFFSET 1;
+```
+
+Опция `WITH TIES` используется для возврата дополнительных строк, которые привязываются к последней в результате запроса. Например, если `fetch_row_count` имеет значение 5 и существуют еще 2 строки с такими же значениями столбцов, указанных в `ORDER BY`, что и у пятой строки результата, то финальный набор будет содержать 7 строк.

-## Секция OFFSET FETCH {#offset-fetch}
-
-`OFFSET` и `FETCH` позволяют извлекать данные по частям. Они указывают строки, которые вы хотите получить в результате запроса.
-
-``` sql
-OFFSET offset_row_count {ROW | ROWS}] [FETCH {FIRST | NEXT} fetch_row_count {ROW | ROWS} {ONLY | WITH TIES}]
-```
-
-`offset_row_count` или `fetch_row_count` может быть числом или литеральной константой. Если вы не используете `fetch_row_count`, то его значение равно 1.
-
-`OFFSET` указывает количество строк, которые необходимо пропустить перед началом возврата строк из запроса.
-
-`FETCH` указывает максимальное количество строк, которые могут быть получены в результате запроса.
-
-Опция `ONLY` используется для возврата строк, которые следуют сразу же за строками, пропущенными секцией `OFFSET`. В этом случае `FETCH` — это альтернатива [LIMIT](../../../sql-reference/statements/select/limit.md). Например, следующий запрос
-
-``` sql
-SELECT * FROM test_fetch ORDER BY a OFFSET 1 ROW FETCH FIRST 3 ROWS ONLY;
-```
-
-идентичен запросу
-
-``` sql
-SELECT * FROM test_fetch ORDER BY a LIMIT 3 OFFSET 1;
-```
-
-Опция `WITH TIES` используется для возврата дополнительных строк, которые привязываются к последней в результате запроса. Например, если `fetch_row_count` имеет значение 5 и существуют еще 2 строки с такими же значениями столбцов, указанных в `ORDER BY`, что и у пятой строки результата, то финальный набор будет содержать 7 строк.
-
-!!! note "Примечание"
-    Секция `OFFSET` должна находиться перед секцией `FETCH`, если обе присутствуют.

-  *
-  * There is a possibility to not initialize elements by default, but create them inplace.
-  * Member destructors are called automatically.
-  *
-  * `sizeof` is equal to the size of one pointer.

-  * Not exception-safe.
-  *
-  * Copying is supported via assign() method. Moving empties the original object.
-  * That is, it is inconvenient to use this array in many cases.
-  *
-  * Designed for situations in which many arrays of the same small size are created,
-  *  but the size is not known at compile time.
-  * Also gives a significant advantage in cases where it is important that `sizeof` is minimal.
-  * For example, if arrays are put in an open-addressing hash table with inplace storage of values (like HashMap)
-  *
-  * In this case, compared to std::vector:
-  * - for arrays of 1 element size - an advantage of about 2 times;
-  * - for arrays of 5 elements - an advantage of about 1.5 times

-///  * Implement interface for IFunction (old function interface, which is planned to be removed sometimes)
-///  * Implement three interfaces for IExecutableFunctionImpl, IFunctionBaseImpl and IFunctionOverloadResolverImpl
-/// Generally saying, IFunction represents a union of three new interfaces. However, it can't be used for all cases.
-/// Examples:
-///  * Function properties may depend on arguments type (e.g. toUInt32(UInt8) is globally monotonic, toUInt32(UInt64) - only on intervals)
-///  * In implementation of lambda functions DataTypeFunction needs an functional object with known arguments and return type
-///  * Function CAST prepares specific implementation based on argument types
-///
-/// Interfaces for IFunction, IExecutableFunctionImpl, IFunctionBaseImpl and IFunctionOverloadResolverImpl are pure.
-/// Default implementations are in adaptors classes (IFunctionAdaptors.h), which are implement user interfaces via developer ones.

+  * Main use cases:

+  *
+  * In LLVM library there are 2 main JIT stacks MCJIT and ORCv2.
+  *
+  * Main reasons for custom implementation vs MCJIT
+  * MCJIT keeps llvm::Module and compiled object code before linking process after module was compiled.
+  * llvm::Module can be removed, but compiled object code cannot be removed. Memory for compiled code
+  * will be release only during MCJIT instance destruction. It is too expensive to create MCJIT
+  * instance for each compiled module.
+  * Also important reason is that if some error occurred during compilation steps, MCJIT can just terminate
+  * our program.
+  *
+  * Main reasons for custom implementation vs ORCv2.
+  * ORC is on request compiler, we do not need support for asynchronous compilation.
+  * It was possible to remove compiled code with ORCv1 but it was deprecated.
+  * In ORCv2 this probably can be done only with custom layer and materialization unit.
+  * But it is inconvenient, discard is only called for materialization units by JITDylib that are not yet materialized.
+  *
+  * CHJIT interface is thread safe, that means all functions can be called from multiple threads and state of CHJIT instance
+  * will not be broken.
+  * It is client responsibility to be sure and do not use compiled code after it was released.

+              with the following parameters:
+                server - one of LDAP server names defined in 'ldap_servers' config section above.
+                        This parameter is mandatory and cannot be empty.
+                roles - section with a list of locally defined roles that will be assigned to each user retrieved from the LDAP server.
+                        If no roles are specified here or assigned during role mapping (below), user will not be able to perform any
+                         actions after authentication.
+                role_mapping - section with LDAP search parameters and mapping rules.
+                        When a user authenticates, while still bound to LDAP, an LDAP search is performed using search_filter and the
+                         name of the logged in user. For each entry found during that search, the value of the specified attribute is
+                         extracted. For each attribute value that has the specified prefix, the prefix is removed, and the rest of the
+                         value becomes the name of a local role defined in ClickHouse, which is expected to be created beforehand by
+                         CREATE ROLE command.
+                        There can be multiple 'role_mapping' sections defined inside the same 'ldap' section. All of them will be
+                         applied.
+                    base_dn - template used to construct the base DN for the LDAP search.
+                            The resulting DN will be constructed by replacing all '{user_name}' and '{bind_dn}' substrings
+                             of the template with the actual user name and bind DN during each LDAP search.
+                    scope - scope of the LDAP search.
+                            Accepted values are: 'base', 'one_level', 'children', 'subtree' (the default).
+                    search_filter - template used to construct the search filter for the LDAP search.
+                            The resulting filter will be constructed by replacing all '{user_name}', '{bind_dn}', and '{base_dn}'
+                             substrings of the template with the actual user name, bind DN, and base DN during each LDAP search.
+                            Note, that the special characters must be escaped properly in XML.
+                    attribute - attribute name whose values will be returned by the LDAP search.
+                    prefix - prefix, that will be expected to be in front of each string in the original list of strings returned by
+                             the LDAP search. Prefix will be removed from the original strings and resulting strings will be treated
+                             as local role names. Empty, by default.
+             Example:
+                <ldap>

+                  (Hamming distance).
+                 in_order - first live replica is chosen in specified order.

+
+                 If you want to specify password in plaintext (not recommended), place it in 'password' element.
+                 Example: <password>qwerty</password>.
+                 Password could be empty.
+
+                 If you want to specify SHA256, place it in 'password_sha256_hex' element.
+                 Example: <password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex>
+                 Restrictions of SHA256: impossibility to connect to ClickHouse using MySQL JS client (as of July 2019).
+
+                 If you want to specify double SHA1, place it in 'password_double_sha1_hex' element.
+                 Example: <password_double_sha1_hex>e395796d6546b1b65db9d665cd43f0e858dd4303</password_double_sha1_hex>
+
+                 If you want to specify a previously defined LDAP server (see 'ldap_servers' in the main config) for authentication,
+                  place its name in 'server' element inside 'ldap' element.
+                 Example: <ldap><server>my_ldap_server</server></ldap>
+
+                 If you want to authenticate the user via Kerberos (assuming Kerberos is enabled, see 'kerberos' in the main config),
+                  place 'kerberos' element instead of 'password' (and similar) elements.
+                 The name part of the canonical principal name of the initiator must match the user name for authentication to succeed.
+                 You can also place 'realm' element inside 'kerberos' element to further restrict authentication to only those requests
+                  whose initiator's realm matches it. 
+                 Example: <kerberos />
+                 Example: <kerberos><realm>EXAMPLE.COM</realm></kerberos>
+
+                 How to generate decent password:
+                 Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
+                 In first line will be password and in second - corresponding SHA256.
+
+                 How to generate double SHA1:
+                 Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha1sum | tr -d '-' | xxd -r -p | sha1sum | tr -d '-'
+                 In first line will be password and in second - corresponding double SHA1.

+
+                 To open access from everywhere, specify:
+                    <ip>::/0</ip>
+
+                 To open access only from localhost, specify:

+                    <ip>127.0.0.1</ip>
+
+                 Each element of list has one of the following forms:
+                 <ip> IP-address or network mask. Examples: 213.180.204.3 or 10.0.0.1/8 or 10.0.0.1/255.255.255.0

+                 <host> Hostname. Example: server01.yandex.ru.
+                     To check access, DNS query is performed, and all received addresses compared to peer address.
+                 <host_regexp> Regular expression for host names. Example, ^server\d\d-\d\d-\d\.yandex\.ru$
+                     To check access, DNS PTR query is performed for peer address and then regexp is applied.
+                     Then, for result of PTR query, another DNS query is performed and all received addresses compared to peer address.
+                     Strongly recommended that regexp is ends with $
+                 All results of DNS requests are cached till server restart.

+    text_from_issue = """BEGIN These examples only show the order that data is arranged in. The values from different columns are stored separately, and data from the same column is stored together.      Examples of a column-oriented DBMS: Vertica, Paraccel (Actian Matrix and Amazon Redshift), Sybase IQ, Exasol, Infobright, InfiniDB, MonetDB (VectorWise and Actian Vector), LucidDB, SAP HANA, Google Dremel, Google PowerDrill, Druid, and kdb+.      Different orders for storing data are better suited to different scenarios. The data access scenario refers to what queries are made, how often, and in what proportion; how much data is read for each type of query – rows, columns, and bytes; the relationship between reading and updating data; the working size of the data and how locally it is used; whether transactions are used, and how isolated they are; requirements for data replication and logical integrity; requirements for latency and throughput for each type of query, and so on.      The higher the load on the system, the more important it is to customize the system set up to match the requirements of the usage scenario, and the more fine grained this customization becomes. There is no system that is equally well-suited to significantly different scenarios. If a system is adaptable to a wide set of scenarios, under a high load, the system will handle all the scenarios equally poorly, or will work well for just one or few of possible scenarios.   Key Properties of OLAP Scenario¶          The vast majority of requests are for read access.       Data is updated in fairly large batches (> 1000 rows), not by single rows; or it is not updated at all.       Data is added to the DB but is not modified.       For reads, quite a large number of rows are extracted from the DB, but only a small subset of columns.       Tables are "wide," meaning they contain a large number of columns.       Queries are relatively rare (usually hundreds of queries per server or less per second).       For simple queries, latencies around 50 ms are allowed.       Column values are fairly small: numbers and short strings (for example, 60 bytes per URL).       Requires high throughput when processing a single query (up to billions of rows per second per server).       Transactions are not necessary.       Low requirements for data consistency.       There is one large table per query. All tables are small, except for one.       A query result is significantly smaller than the source data. In other words, data is filtered or aggregated, so the result fits in a single server"s RAM.      It is easy to see that the OLAP scenario is very different from other popular scenarios (such as OLTP or Key-Value access). So it doesn"t make sense to try to use OLTP or a Key-Value DB for processing analytical queries if you want to get decent performance. For example, if you try to use MongoDB or Redis for analytics, you will get very poor performance compared to OLAP databases.   Why Column-Oriented Databases Work Better in the OLAP Scenario¶      Column-oriented databases are better suited to OLAP scenarios: they are at least 100 times faster in processing most queries. The reasons are explained in detail below, but the fact is easier to demonstrate visually. END"""

+                 Password could be empty.

+[9961200,73476000,325666800,354675600,370400400,386125200,388566010,401850000,417574811,496803600,528253200,624423614,636516015,671011200,717555600,752047218,859683600,922582800,1018173600,1035705600,1143334800,1162105223,1174784400,1194156000,1206838823,1224982823,1236495624,1319936400,1319936424,1425798025,1459040400,1509872400,2090451627,2140668000]
+```
+
+
+### Specific
+
+##### RQ.SRS-010.DateTime64.ExtendedRange.Start
+version: 1.0
+
+[ClickHouse] SHALL support extended range for the [DateTime64] data type that starts at `1925-01-01T00:00:00.000000`
+expressed using the [ISO 8601 format].
+
+##### RQ.SRS-010.DateTime64.ExtendedRange.End
+version: 1.0
+
+[ClickHouse] SHALL support extended range for the [DateTime64] data type that ends at `2238-12-31T23:59:59.999999`
+expressed using the [ISO 8601 format].
+
+##### Non-Existent Time
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.InvalidDate
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid dates when using [DateTime64] extended range data type,
+such as:
+
+* `YYYY-04-31, YYYY-06-31, YYYY-09-31, YYYY-11-31`
+* `1990-02-30 00:00:02`
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.InvalidTime
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time for a timezone
+when using [DateTime64] extended range data type, for example,
+
+* `2002-04-07 02:30:00` never happened at all in the US/Eastern timezone ([Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime))
+
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.TimeZoneSwitch
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time when using [DateTime64] extended range data type
+when the invalid time is caused when *countries switch timezone definitions with no
+daylight savings time switch* [Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime).
+
+>
+> For example, in 1915 Warsaw switched from Warsaw time to Central European time with
+> no daylight savings transition. So at the stroke of midnight on August 5th 1915 the clocks
+> were wound back 24 minutes creating an ambiguous time period that cannot be specified without
+> referring to the timezone abbreviation or the actual UTC offset. In this case midnight happened twice,
+> neither time during a daylight saving time period. pytz handles this transition by treating the ambiguous
+> period before the switch as daylight savings time, and the ambiguous period after as standard time.
+>
+> [Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime)
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.DaylightSavingTime
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time when using [DateTime64] extended range data type
+when for a given timezone time switches from standard to daylight saving.
+
+> For example, in the US/Eastern timezone on the last Sunday morning in October, the following sequence happens:
+>
+> 01:00 EDT occurs
+> 1 hour later, instead of 2:00am the clock is turned back 1 hour and 01:00 happens again (this time 01:00 EST)
+> In fact, every instant between 01:00 and 02:00 occurs twice.
+> [Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime)
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.DaylightSavingTime.Disappeared
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time when using [DateTime64] extended range data type
+for a given timezone when transition from the standard to daylight saving time causes an hour to disappear.
+
+Expected behavior: if DateTime64 initialized by a skipped time value, it is being treated as DST and resulting value will be an hour earlier, e.g. `SELECT toDateTime64('2020-03-08 02:34:00', 0, 'America/Denver')` returns `2020-03-08 01:34:00`.
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.LeapSeconds
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of leap seconds adjustments when using [DateTime64] extended range data type.

+[ClickHouse] SHALL properly work with the following timestamps in all supported timezones:
+```
+[9961200,73476000,325666800,354675600,370400400,386125200,388566010,401850000,417574811,496803600,528253200,624423614,636516015,671011200,717555600,752047218,859683600,922582800,1018173600,1035705600,1143334800,1162105223,1174784400,1194156000,1206838823,1224982823,1236495624,1319936400,1319936424,1425798025,1459040400,1509872400,2090451627,2140668000]
+```
+
+
+### Specific
+
+##### RQ.SRS-010.DateTime64.ExtendedRange.Start
+version: 1.0
+
+[ClickHouse] SHALL support extended range for the [DateTime64] data type that starts at `1925-01-01T00:00:00.000000`
+expressed using the [ISO 8601 format].
+
+##### RQ.SRS-010.DateTime64.ExtendedRange.End
+version: 1.0
+
+[ClickHouse] SHALL support extended range for the [DateTime64] data type that ends at `2238-12-31T23:59:59.999999`
+expressed using the [ISO 8601 format].
+
+##### Non-Existent Time
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.InvalidDate
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid dates when using [DateTime64] extended range data type,
+such as:
+
+* `YYYY-04-31, YYYY-06-31, YYYY-09-31, YYYY-11-31`
+* `1990-02-30 00:00:02`
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.InvalidTime
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time for a timezone
+when using [DateTime64] extended range data type, for example,
+
+* `2002-04-07 02:30:00` never happened at all in the US/Eastern timezone ([Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime))
+
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.TimeZoneSwitch
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time when using [DateTime64] extended range data type
+when the invalid time is caused when *countries switch timezone definitions with no
+daylight savings time switch* [Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime).
+
+>
+> For example, in 1915 Warsaw switched from Warsaw time to Central European time with
+> no daylight savings transition. So at the stroke of midnight on August 5th 1915 the clocks
+> were wound back 24 minutes creating an ambiguous time period that cannot be specified without
+> referring to the timezone abbreviation or the actual UTC offset. In this case midnight happened twice,
+> neither time during a daylight saving time period. pytz handles this transition by treating the ambiguous
+> period before the switch as daylight savings time, and the ambiguous period after as standard time.
+>
+> [Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime)
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.DaylightSavingTime
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time when using [DateTime64] extended range data type
+when for a given timezone time switches from standard to daylight saving.
+
+> For example, in the US/Eastern timezone on the last Sunday morning in October, the following sequence happens:
+>
+> 01:00 EDT occurs
+> 1 hour later, instead of 2:00am the clock is turned back 1 hour and 01:00 happens again (this time 01:00 EST)
+> In fact, every instant between 01:00 and 02:00 occurs twice.
+> [Stuart Bishop: pytz library](http://pytz.sourceforge.net/#problems-with-localtime)
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.DaylightSavingTime.Disappeared
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of invalid time when using [DateTime64] extended range data type
+for a given timezone when transition from the standard to daylight saving time causes an hour to disappear.
+
+Expected behavior: if DateTime64 initialized by a skipped time value, it is being treated as DST and resulting value will be an hour earlier, e.g. `SELECT toDateTime64('2020-03-08 02:34:00', 0, 'America/Denver')` returns `2020-03-08 01:34:00`.
+
+###### RQ.SRS-010.DateTime64.ExtendedRange.NonExistentTime.LeapSeconds
+version: 1.0
+
+[ClickHouse] SHALL support proper handling of leap seconds adjustments when using [DateTime64] extended range data type.

+                 Password could be empty.

+            <!-- How to choose between replicas during distributed query processing.
+                 random - choose random replica from set of replicas with minimum number of errors
+                 nearest_hostname - from set of replicas with minimum number of errors, choose replica
+                  with minimum number of different symbols between replica's hostname and local hostname
+                  (Hamming distance).
+                 in_order - first live replica is chosen in specified order.
+                 first_or_random - if first replica one has higher number of errors, pick a random one from replicas with minimum number of errors.

+            <!-- Password could be specified in plaintext or in SHA256 (in hex format).
+
+                 If you want to specify password in plaintext (not recommended), place it in 'password' element.
+                 Example: <password>qwerty</password>.
+                 Password could be empty.
+
+                 If you want to specify SHA256, place it in 'password_sha256_hex' element.
+                 Example: <password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex>
+                 Restrictions of SHA256: impossibility to connect to ClickHouse using MySQL JS client (as of July 2019).
+
+                 If you want to specify double SHA1, place it in 'password_double_sha1_hex' element.
+                 Example: <password_double_sha1_hex>e395796d6546b1b65db9d665cd43f0e858dd4303</password_double_sha1_hex>
+
+                 How to generate decent password:

+                 In first line will be password and in second - corresponding SHA256.
+
+                 How to generate double SHA1:
+                 Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | openssl dgst -sha1 -binary | openssl dgst -sha1

+                 <host> Hostname. Example: server01.yandex.ru.
+                     To check access, DNS query is performed, and all received addresses compared to peer address.

+                     To check access, DNS PTR query is performed for peer address and then regexp is applied.
+                     Then, for result of PTR query, another DNS query is performed and all received addresses compared to peer address.
+                     Strongly recommended that regexp is ends with $

+## Introduction
+
+This software requirements specification covers requirements for supporting window functions in [ClickHouse].
+Similar functionality exists in [MySQL] and [PostreSQL]. [PostreSQL] defines a window function as follows:
+
+> A window function performs a calculation across a set of table rows that are somehow related to the current row.
+> This is comparable to the type of calculation that can be done with an aggregate function.
+> But unlike regular aggregate functions, use of a window function does not cause rows to
+> become grouped into a single output row — the rows retain their separate identities.
+
+## Requirements
+
+### General
+
+#### RQ.SRS-019.ClickHouse.WindowFunctions
+version: 1.0
+
+[ClickHouse] SHALL support [window functions] that produce a result for each row inside the window.
+
+#### RQ.SRS-019.ClickHouse.WindowFunctions.NonDistributedTables
+version: 1.0
+
+[ClickHouse] SHALL support correct operation of [window functions] on non-distributed 
+table engines such as `MergeTree`.
+
+
+#### RQ.SRS-019.ClickHouse.WindowFunctions.DistributedTables
+version: 1.0
+
+[ClickHouse] SHALL support correct operation of [window functions] on
+[Distributed](https://clickhouse.tech/docs/en/engines/table-engines/special/distributed/) table engine.

+###### RQ.SRS-019.ClickHouse.WindowFunctions.Rank
+version: 1.0
+
+[ClickHouse] SHALL support `rank` window function that SHALL
+return the rank of the current row within its partition with gaps.
+
+Peers SHALL be considered ties and receive the same rank.
+The function SHALL not assign consecutive ranks to peer groups if groups of size greater than one exist
+and the result is noncontiguous rank numbers.
+
+If the function is used without `ORDER BY` to sort partition rows into the desired order
+then all rows SHALL be peers.
+
+```
+rank() OVER ...
+```
+
+##### The `dense_rank()` Function
+
+###### RQ.SRS-019.ClickHouse.WindowFunctions.DenseRank
+version: 1.0
+
+[ClickHouse] SHALL support `dense_rank` function over a window that SHALL
+return the rank of the current row within its partition without gaps.
+
+Peers SHALL be considered ties and receive the same rank.
+The function SHALL assign consecutive ranks to peer groups and
+the result is that groups of size greater than one do not produce noncontiguous rank numbers.
+
+If the function is used without `ORDER BY` to sort partition rows into the desired order
+then all rows SHALL be peers.
+
+```
+dense_rank() OVER ...
+```
+
+##### The `row_number()` Function
+
+###### RQ.SRS-019.ClickHouse.WindowFunctions.RowNumber
+version: 1.0
+
+[ClickHouse] SHALL support `row_number` function over a window that SHALL
+returns the number of the current row within its partition.
+
+Rows numbers SHALL range from 1 to the number of partition rows.
+
+The `ORDER BY` affects the order in which rows are numbered.
+Without `ORDER BY`, row numbering MAY be nondeterministic.

+> A window function performs a calculation across a set of table rows that are somehow related to the current row.
+> This is comparable to the type of calculation that can be done with an aggregate function.
+> But unlike regular aggregate functions, use of a window function does not cause rows to
+> become grouped into a single output row — the rows retain their separate identities.

+returned for the current row.
+
+##### The `lead(value, offset)` Function Workaround
+
+###### RQ.SRS-019.ClickHouse.WindowFunctions.Lead.Workaround
+version: 1.0
+
+[ClickHouse] SHALL support a workaround for the `lead(value, offset)` function as
+
+```
+any(value) OVER (.... ROWS BETWEEN <offset> FOLLOWING AND <offset> FOLLOWING)
+```
+
+The function SHALL returns the value from the row that leads (follows) the current row by
+the `N` rows within its partition. Where `N` is the `value` passed to the `any` function.
+
+If there is no such row, the return value SHALL be default.
+
+For example, if `N` is 3, the return value is default for the last two rows.
+If `N` or default are missing, the defaults are 1 and NULL, respectively.
+
+`N` SHALL be a literal non-negative integer. If `N` is 0, the value SHALL be
+returned for the current row.
+
+##### The `rank()` Function
+
+###### RQ.SRS-019.ClickHouse.WindowFunctions.Rank
+version: 1.0
+
+[ClickHouse] SHALL support `rank` window function that SHALL
+return the rank of the current row within its partition with gaps.
+
+Peers SHALL be considered ties and receive the same rank.
+The function SHALL not assign consecutive ranks to peer groups if groups of size greater than one exist
+and the result is noncontiguous rank numbers.
+
+If the function is used without `ORDER BY` to sort partition rows into the desired order
+then all rows SHALL be peers.
+
+```
+rank() OVER ...
+```
+
+##### The `dense_rank()` Function
+
+###### RQ.SRS-019.ClickHouse.WindowFunctions.DenseRank
+version: 1.0
+
+[ClickHouse] SHALL support `dense_rank` function over a window that SHALL
+return the rank of the current row within its partition without gaps.
+
+Peers SHALL be considered ties and receive the same rank.
+The function SHALL assign consecutive ranks to peer groups and
+the result is that groups of size greater than one do not produce noncontiguous rank numbers.
+
+If the function is used without `ORDER BY` to sort partition rows into the desired order
+then all rows SHALL be peers.
+
+```
+dense_rank() OVER ...
+```
+
+##### The `row_number()` Function
+
+###### RQ.SRS-019.ClickHouse.WindowFunctions.RowNumber
+version: 1.0
+
+[ClickHouse] SHALL support `row_number` function over a window that SHALL
+returns the number of the current row within its partition.
+
+Rows numbers SHALL range from 1 to the number of partition rows.
+
+The `ORDER BY` affects the order in which rows are numbered.
+Without `ORDER BY`, row numbering MAY be nondeterministic.
+
+```
+row_number() OVER ...
+```
+
+#### Aggregate Functions
+
+##### RQ.SRS-019.ClickHouse.WindowFunctions.AggregateFunctions

+title: 'The Tests Are Passing, Why Would I Read The Diff Again?'

+
+
+Code review is one of the few software development techniques that are consistently found to reduce the incidence of defects. Why is it effective? This article offers some wild conjecture on this topic, complete with practical advice on getting the most out of your code review.
+
+
+## Understanding Why Your Program Works
+
+As software developers, we routinely have to reason about the behaviour of software. For example, to fix a bug, we start with a test case that exhibits the behavior in question, and then read the source code to see how this behavior arises. Often we find ourselves unable to understand anything, having to resort to forensic techniques such as using a debugger or interrogating the author of the code. This situation is far from ideal. After all, if we have trouble understanding our software, how can we be sure it works at all? No surprise that it doesn't.
+
+The correct understanding is also important when modifying and extending software. A programmer must always have a precise mental model on what is going on in the program, how exactly it maps to the domain, and so on. If there are flaws in this model, the code they write won't match the domain and won't solve the problem correctly. Wrong understanding directly causes bugs.
+
+How can we make our software easier to understand? It is often said that to see if you really understand something, you have to try explaining it to somebody. For example, as a science student taking an exam, you might be expected to give an explanation to some well-known observed effect, deriving it from the basic laws of this domain. In a similar way, if we are modeling some problem in software, we can start from domain knowledge and general programming knowledge, and build an argument as to why our model is applicable to the problem, why it is correct, has optimal performance and so on. This explanation takes the form of code comments, or, at a higher level, design documents.
+
+If you have a habit of thoroughly commenting your code, you might have noticed that writing the comments is often much harder than writing the code itself. It also has an unpleasant side effect &mdash; at times, while writing a comment, it becomes increasingly clear to you that the code is incomprehensible and takes forever to explain, or maybe is downright wrong, and you have to rewrite it. This is exactly the major positive effect of writing the comments. It helps you find bugs and make the code more understandable, and you wouldn't have noticed these problems unless you tried to explain the code.
+
+Understanding why your program works is inseparable from understanding why it fails, so it's no surprise that there is a similar process for the latter, called "rubber duck debugging". To debug a particularly nasty bug, you start explaining the program logic step by step to an imaginary partner or even to an inanimate object such as a yellow rubber duck. This process is often very effective, much in excess of what one would expect given the limited conversational abilities of rubber ducks. The underlying mechanism is probably the same as with comments &mdash; you start to understand your program better by just trying to explain it, and this lets you find bugs.
+
+When working in a team, you even have a luxury of explaining your code to another developer who works on the same project. It's probably more entertaining than talking to a duck. More importantly, they are going to maintain the code you wrote, so better make sure that _they_ can understand it as well. A good formal occasion for explaining how your code works is the code review process. Let's see how you can get the most out of it, in terms of making your code understandable.
+
+## Reviewing Others Code
+
+Code review is often framed as a gatekeeping process, where each contribution is vetted by maintainers to ensure that it is in line with project direction, has acceptable quality, meets the coding guidelines and so on. This perspective might seem natural when dealing with external contributions, but makes less sense if you apply it to internal ones. After all, our fellow maintainers have perfect understanding of project goals and guidelines, probably they are more talented and experienced than us, and can be trusted to produce the best solution possible. How can an additional review be helpful?
+
+A less-obvious, but very important, part of reviewing the code is just seeing whether it can be understood by another person. It is helpful regardless of the administrative roles and programming proficiency of the parties. What should you do as a reviewer if ease of understanding is your main priority?
+
+You probably don't need to be concerned with trivia such as code style. There are automated tools for that. You might find some bugs, but this is probably a side effect. Your main task is making sense of the code.
+
+Start with checking the high-level description of the problem that the pull request is trying to solve. Read the description of the bug it fixes, or the docs for the feature it adds. For bigger features, there is normally a design document that describes the overall implementation without getting too deep into the code details. After you understand the problem, start reading the code. Does it make sense to you? You shouldn't try too hard to understand it. Imagine that you are tired and under time pressure. If you feel you have to make a lot of effort to understand the code, ask the author for clarifications. As you talk, you might discover that the code is not correct, or it may be rewritten in a more straightforward way, or it needs more comments.
+
+<img src="https://blog-images.clickhouse.tech/en/2021/code-review/hidden-items.png"/>
+
+After you get the answers, don't forget to update the code and the comments to reflect them. Don't just stop after getting it explained to you personally. If you had a question as a reviewer, chances are that other people will also have this question later, but there might be nobody around to ask. They will have to resort to `git blame` and re-reading the entire pull request or several of them. Code archaeology is sometimes fun, but it's the last thing you want to do when you are investigating an urgent bug. All the answers should be on the surface.
+
+Working with the author, you should ensure that the code is mostly obvious to anyone with basic domain and programming knowledge, and all non-obvious parts are clearly explained.
+
+### Preparing Your Code For Review
+
+As an author, you can also do some things to make your code easier to understand for the reviewer.
+
+First of all, if you are implementing a major feature, it probably needs a round of design review before you even start writing code. Skipping a design review and jumping right into the code review can be a major source of frustration, because it might turn out that even the problem you are solving was formulated incorrectly, and all your work has to be thrown away. Of course, this is not prevented completely by design review, either. Programming is an iterative, exploratory activity, and in complex cases you only begin to grasp the problem after implementing a first solution, which you then realize is incorrect and has to be thrown away.
+
+When preparing your code for review, your major objective is to make your problem and its solution clear to the reviewer. A good tool for this is code comments. Any sizable piece of logic should have an introductory comment describing its general purpose and outlining the implementation. This description can reference similar features, explain the difference to them, explain how it interfaces with other subsystems. A good place to put this general description is a function that serves as a main entry point for the feature, or other form of its public interface, or the most significant class, or the file containing the implementation, and so on.
+
+Drilling down to each block of code, you should be able to explain what it does, why it does that, why this way and not another. If there are several ways of doing the thing, why did you choose this one? Of course, for some code these things follow from the more general comments and don't have to be restated. The mechanics of data manipulation should be apparent from the code itself. If you find yourself explaining a particular feature of the language, it's probably best not to use it.
+
+Pay special attention to making the data structures apparent in the code, and their meaning and invariants well commented. The choice of data structures ultimately determines which algorithms you can apply, and sets the limits of performance, which is another reason why we should care about it as ClickHouse developers. 
+
+When explaining the code, it is important to give your reader enough context, so that they can understand you without a deep investigation of the surrounding systems and obscure test cases. Give pointers to all the things that might be relevant to the task. If you know some corner cases which your code has to handle, describe them in enough detail so that they can be reproduced. If there is a relevant standard or a design document, reference it, or even quote it inline. If you're relying on some invariant in other system, mention it. It is good practice to add programmatic checks that mirror your comments, when it is easy to do so. Your comment about an invariant should be accompanied by an assertion, and an important scenario should be reproduced by a test case.
+
+Don't worry about being too verbose. There is often not enough comments, but almost never too much of them.
+
+## Common Concerns about Code Comments
+
+It is common to hear objections to the idea of commenting the code, so let's discuss a couple of usual ones.
+
+### Self-documenting Code
+
+You can often see a perplexing idea that the source code can somehow be "self-documenting", or that the comments are a "code smell", and their presence indicates that the code is badly written. I have trouble imagining how this belief can be compatible with any experience in maintaining sufficiently complex and large software, over the years, in collaboration with others. The code and the comments describe different parts of the solution. The code describes the data structures and their transformations, but it cannot convey meaning. The names in the code serve as pointers that map the data and its transformations to the domain concepts, but they are schematic and lack nuance. It is not so difficult to write code that makes it easy to understand what's going on in terms of data manipulation. What it takes is mostly moderation, that is, stopping yourself from being too clever. For most code, it is easy to see what it does, but why? Why this way and not that way? Why is it correct? Why this fast path here helps? Why did you choose this data layout? How is this invariant guaranteed? And so on. This might be not so evident for a developer who is working alone on a short-lived project, because they have all the necessary context in their head. But when they have to work with other people (or even with themselves from past and future), or in an unfamiliar area, the importance of non-code, higher-level context becomes painfully clear. The idea that we should, or even can, somehow encode comments such as [this one](https://github.com/ClickHouse/ClickHouse/blob/26d5db32ae5c9f54b8825e2eca1f077a3b17c84a/src/Storages/MergeTree/KeyCondition.cpp#L1312-L1347) into names or control flow is just absurd.
+
+### Obsolete Comments
+
+The comments can't be checked by the compiler or the tests, so there is no automated way to make sure that they are up to date with the rest of the comments and the code. The possibility of comments gradually getting incorrect is sometimes used as an argument against having any comments at all.
+
+This problem is not exclusive to the comments &mdash; the code also can and does become obsolete. Simple cases such as dead code can be detected by static analysis or studying the test coverage of code. More complex cases can only be found by proofreading, such as maintaining an invariant that is not important anymore, or preparing some data that is not needed.
+
+While an obsolete comment can lead to a mistake, the same applies, perhaps more strongly, to the lack of comments. When you need some higher-level knowledge about the code, but it is not written down, you are forced to perform an entire investigation from first principles to understand what's going on, and this is error-prone. Even an obsolete comment likely gives a better starting point than nothing. Moreover, in a code base that makes an active use of the comments, they tend to be mostly correct. This is because the developers rely on comments, read and write them, pay attention to them during code review. The comments are routinely changed along with changing the code, and the outdated comments are soon noticed and fixed. This does require some habit. A lone comment in a vast desert of impenetrable self-documenting code is not going to fare well.
+
+
+## Conclusion
+
+Code review makes your software better, and a significant part of this probably comes from trying to understand what your software actually does. By paying attention specifically to this aspect of code review, you can make it even more efficient. You'll have less bugs, and your code will be easier to maintain &mdash; and what else could we ask for as software developers?
