## 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)).
* Improve performance of aggregation in order of sorting key (with enabled setting `optimize_aggregation_in_order`). [#19401](https://github.com/ClickHouse/ClickHouse/pull/19401) ([Anton Popov](https://github.com/CurtizJ)).
#### Improvement
* Add connection pool for PostgreSQL table/database engine and dictionary source. Should fix [#21444](https://github.com/ClickHouse/ClickHouse/issues/21444). [#21839](https://github.com/ClickHouse/ClickHouse/pull/21839) ([Kseniia Sumarokova](https://github.com/kssenii)).
* 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)).
* Better exception message in client in case of exception while server is writing blocks. In previous versions client may get misleading message like `Data compressed with different methods`. [#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)).
* Fix MSan report for function `range` with `UInt256` argument (support for large integers is experimental). This closes [#22157](https://github.com/ClickHouse/ClickHouse/issues/22157). [#22387](https://github.com/ClickHouse/ClickHouse/pull/22387) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Add `current_database` column to `system.processes` table. It contains the current database of the query. [#22365](https://github.com/ClickHouse/ClickHouse/pull/22365) ([Alexander Kuzmenkov](https://github.com/akuzm)).
* Add case-insensitive history search/navigation and subword movement features to `clickhouse-client`. [#22105](https://github.com/ClickHouse/ClickHouse/pull/22105) ([Amos Bird](https://github.com/amosbird)).
* If tuple of NULLs, e.g. `(NULL, NULL)` is on the left hand side of `IN` operator with tuples of non-NULLs on the right hand side, e.g. `SELECT (NULL, NULL) IN ((0, 0), (3, 1))` return 0 instead of throwing an exception about incompatible types. 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)).
* Update used version of simdjson to 0.9.1. This fixes [#21984](https://github.com/ClickHouse/ClickHouse/issues/21984). [#22057](https://github.com/ClickHouse/ClickHouse/pull/22057) ([Vitaly Baranov](https://github.com/vitlibar)).
* Added case insensitive aliases for `CONNECTION_ID()` and `VERSION()` functions. This fixes [#22028](https://github.com/ClickHouse/ClickHouse/issues/22028). [#22042](https://github.com/ClickHouse/ClickHouse/pull/22042) ([Eugene Klimov](https://github.com/Slach)).
* Add option `strict_increase` to `windowFunnel` function to calculate each event once (resolve [#21835](https://github.com/ClickHouse/ClickHouse/issues/21835)). [#22025](https://github.com/ClickHouse/ClickHouse/pull/22025) ([Vladimir](https://github.com/vdimir)).
* 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)).
* Supported `replication_alter_partitions_sync=1` setting in `clickhouse-copier` for moving partitions from helping table to destination. Decreased default timeouts. Fixes [#21911](https://github.com/ClickHouse/ClickHouse/issues/21911). [#21912](https://github.com/ClickHouse/ClickHouse/pull/21912) ([turbo jason](https://github.com/songenjie)).
* Show path to data directory of `EmbeddedRocksDB` tables in system tables. [#21903](https://github.com/ClickHouse/ClickHouse/pull/21903) ([tavplubix](https://github.com/tavplubix)).
* Add profile event `HedgedRequestsChangeReplica`, change read data timeout from sec to ms. [#21886](https://github.com/ClickHouse/ClickHouse/pull/21886) ([Kruglov Pavel](https://github.com/Avogar)).
* DiskS3 (experimental feature under development). Fixed bug with the impossibility to move directory if the destination is not empty and cache disk is used. [#21837](https://github.com/ClickHouse/ClickHouse/pull/21837) ([Pavel Kovalenko](https://github.com/Jokser)).
* Better formatting for `Array` and `Map` data types in Web UI. [#21798](https://github.com/ClickHouse/ClickHouse/pull/21798) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Update clusters only if their configurations were updated. [#21685](https://github.com/ClickHouse/ClickHouse/pull/21685) ([Kruglov Pavel](https://github.com/Avogar)).
* Propagate query and session settings for distributed DDL queries. Set `distributed_ddl_entry_format_version` to 2 to enable this. Added `distributed_ddl_output_mode` setting. Supported modes: `none`, `throw` (default), `null_status_on_timeout` and `never_throw`. Miscellaneous fixes and improvements for `Replicated` database engine. [#21535](https://github.com/ClickHouse/ClickHouse/pull/21535) ([tavplubix](https://github.com/tavplubix)).
* If `PODArray` was instantiated with element size that is neither a fraction or a multiple of 16, buffer overflow was possible. No bugs in current releases exist. [#21533](https://github.com/ClickHouse/ClickHouse/pull/21533) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Add `last_error_time`/`last_error_message`/`last_error_stacktrace`/`remote` columns for `system.errors`. [#21529](https://github.com/ClickHouse/ClickHouse/pull/21529) ([Azat Khuzhin](https://github.com/azat)).
* Add aliases `simpleJSONExtract/simpleJSONHas` to `visitParam/visitParamExtract{UInt, Int, Bool, Float, Raw, String}`. Fixes #21383. [#21519](https://github.com/ClickHouse/ClickHouse/pull/21519) ([fastio](https://github.com/fastio)).
* Add setting `optimize_skip_unused_shards_limit` to limit the number of sharding key values for `optimize_skip_unused_shards`. [#21512](https://github.com/ClickHouse/ClickHouse/pull/21512) ([Azat Khuzhin](https://github.com/azat)).
* Improve `clickhouse-format` to not throw exception when there are extra spaces or comment after the last query, and throw exception early with readable message when format `ASTInsertQuery` with data . [#21311](https://github.com/ClickHouse/ClickHouse/pull/21311) ([flynn](https://github.com/ucasFL)).
* Improve support of integer keys in data type `Map`. [#21157](https://github.com/ClickHouse/ClickHouse/pull/21157) ([Anton Popov](https://github.com/CurtizJ)).
* MaterializeMySQL: attempt to reconnect to MySQL if the connection is lost. [#20961](https://github.com/ClickHouse/ClickHouse/pull/20961) ([Håvard Kvålen](https://github.com/havardk)).
* Support more cases to rewrite `CROSS JOIN` to `INNER JOIN`. [#20392](https://github.com/ClickHouse/ClickHouse/pull/20392) ([Vladimir](https://github.com/vdimir)).
* Do not create empty parts on INSERT when `optimize_on_insert` setting enabled. Fixes [#20304](https://github.com/ClickHouse/ClickHouse/issues/20304). [#20387](https://github.com/ClickHouse/ClickHouse/pull/20387) ([Kruglov Pavel](https://github.com/Avogar)).
* `MaterializeMySQL`: add minmax skipping index for `_version` column. [#20382](https://github.com/ClickHouse/ClickHouse/pull/20382) ([Stig Bakken](https://github.com/stigsb)).
* Add option `--backslash` for `clickhouse-format`, which can add a backslash at the end of each line of the formatted query. [#21494](https://github.com/ClickHouse/ClickHouse/pull/21494) ([flynn](https://github.com/ucasFL)).
* Now clickhouse will not throw `LOGICAL_ERROR` exception when we try to mutate the already covered part. Fixes [#22013](https://github.com/ClickHouse/ClickHouse/issues/22013). [#22291](https://github.com/ClickHouse/ClickHouse/pull/22291) ([alesapin](https://github.com/alesapin)).
#### Bug Fix
* Remove socket from epoll before cancelling packet receiver in `HedgedConnections` to prevent possible race. Fixes [#22161](https://github.com/ClickHouse/ClickHouse/issues/22161). [#22443](https://github.com/ClickHouse/ClickHouse/pull/22443) ([Kruglov Pavel](https://github.com/Avogar)).
* Add (missing) memory accounting in parallel parsing routines. In previous versions OOM was possible when the resultset contains very large blocks of data. This closes [#22008](https://github.com/ClickHouse/ClickHouse/issues/22008). [#22425](https://github.com/ClickHouse/ClickHouse/pull/22425) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Fix exception which may happen when `SELECT` has constant `WHERE` condition and source table has columns which names are digits. [#22270](https://github.com/ClickHouse/ClickHouse/pull/22270) ([LiuNeng](https://github.com/liuneng1994)).
* Fix query cancellation with `use_hedged_requests=0` and `async_socket_for_remote=1`. [#22183](https://github.com/ClickHouse/ClickHouse/pull/22183) ([Azat Khuzhin](https://github.com/azat)).

#### Build/Testing/Packaging Improvement
* Add [Jepsen](https://github.com/jepsen-io/jepsen) tests for ClickHouse Keeper. [#21677](https://github.com/ClickHouse/ClickHouse/pull/21677) ([alesapin](https://github.com/alesapin)).
* Run stateless tests in parallel in CI. Depends on [#22181](https://github.com/ClickHouse/ClickHouse/issues/22181). [#22300](https://github.com/ClickHouse/ClickHouse/pull/22300) ([alesapin](https://github.com/alesapin)).
* Enable status check for [SQLancer](https://github.com/sqlancer/sqlancer) CI run. [#22015](https://github.com/ClickHouse/ClickHouse/pull/22015) ([Ilya Yatsishin](https://github.com/qoega)).
* Multiple preparations for PowerPC builds: Enable the bundled openldap on `ppc64le`. [#22487](https://github.com/ClickHouse/ClickHouse/pull/22487) ([Kfir Itzhak](https://github.com/mastertheknife)).

[#22445](https://github.com/ClickHouse/ClickHouse/pull/22445) ([Kfir Itzhak](https://github.com/mastertheknife)). Fixed compiling on `ppc64le` and use the correct instruction pointer register on `ppc64le`. [#22430](https://github.com/ClickHouse/ClickHouse/pull/22430) ([Kfir Itzhak](https://github.com/mastertheknife)).
* Re-enable the S3 (AWS) library on `aarch64`. [#22484](https://github.com/ClickHouse/ClickHouse/pull/22484) ([Kfir Itzhak](https://github.com/mastertheknife)).
* Add `tzdata` to Docker containers because reading `ORC` formats requires it. This closes [#14156](https://github.com/ClickHouse/ClickHouse/issues/14156). [#22000](https://github.com/ClickHouse/ClickHouse/pull/22000) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Introduce 2 arguments for `clickhouse-server` image Dockerfile: `deb_location` & `single_binary_location`. [#21977](https://github.com/ClickHouse/ClickHouse/pull/21977) ([filimonov](https://github.com/filimonov)).
* Allow to use clang-tidy with release builds by enabling assertions if it is used. [#21914](https://github.com/ClickHouse/ClickHouse/pull/21914) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Add llvm-12 binaries name to search in cmake scripts. Implicit constants conversions to mute clang warnings. Updated submodules to build with CMake 3.19. Mute recursion in macro expansion in `readpassphrase` library. Deprecated `-fuse-ld` changed to `--ld-path` for clang. [#21597](https://github.com/ClickHouse/ClickHouse/pull/21597) ([Ilya Yatsishin](https://github.com/qoega)).
* Updating `docker/test/testflows/runner/dockerd-entrypoint.sh` to use Yandex dockerhub-proxy, because Docker Hub has enabled very restrictive rate limits [#21551](https://github.com/ClickHouse/ClickHouse/pull/21551) ([vzakaznikov](https://github.com/vzakaznikov)).

## ClickHouse release 21.3 (LTS)
### ClickHouse release v21.3, 2021-03-12
#### Backward Incompatible Change
* Now it's not allowed to create MergeTree tables in old syntax with table TTL because it's just ignored. Attach of old tables is still possible. [#20282](https://github.com/ClickHouse/ClickHouse/pull/20282) ([alesapin](https://github.com/alesapin)).
* Now all case-insensitive function names will be rewritten to their canonical representations. This is needed for projection query routing (the upcoming feature). [#20174](https://github.com/ClickHouse/ClickHouse/pull/20174) ([Amos Bird](https://github.com/amosbird)).
* Fix creation of `TTL` in cases, when its expression is a function and it is the same as `ORDER BY` key. Now it's allowed to set custom aggregation to primary key columns in `TTL` with `GROUP BY`. Backward incompatible: For primary key columns, which are not in `GROUP BY` and aren't set explicitly now is applied function `any` instead of `max`, when TTL is expired. Also if you use TTL with `WHERE` or `GROUP BY` you can see exceptions at merges, while making rolling update. [#15450](https://github.com/ClickHouse/ClickHouse/pull/15450) ([Anton Popov](https://github.com/CurtizJ)).
#### New Feature
* Add file engine settings: `engine_file_empty_if_not_exists` and `engine_file_truncate_on_insert`. [#20620](https://github.com/ClickHouse/ClickHouse/pull/20620) ([M0r64n](https://github.com/M0r64n)).
* Add aggregate function `deltaSum` for summing the differences between consecutive rows. [#20057](https://github.com/ClickHouse/ClickHouse/pull/20057) ([Russ Frank](https://github.com/rf)).
* New `event_time_microseconds` column in `system.part_log` table. [#20027](https://github.com/ClickHouse/ClickHouse/pull/20027) ([Bharat Nallan](https://github.com/bharatnc)).
* Added `timezoneOffset(datetime)` function which will give the offset from UTC in seconds. This close [#issue:19850](https://github.com/ClickHouse/ClickHouse/issues/19850). [#19962](https://github.com/ClickHouse/ClickHouse/pull/19962) ([keenwolf](https://github.com/keen-wolf)).
* Add setting `insert_shard_id` to support insert data into specific shard from distributed table. [#19961](https://github.com/ClickHouse/ClickHouse/pull/19961) ([flynn](https://github.com/ucasFL)).
* Function `reinterpretAs` updated to support big integers. Fixes [#19691](https://github.com/ClickHouse/ClickHouse/issues/19691). [#19858](https://github.com/ClickHouse/ClickHouse/pull/19858) ([Maksim Kita](https://github.com/kitaisreal)).
* Added Server Side Encryption Customer Keys (the `x-amz-server-side-encryption-customer-(key/md5)` header) support in S3 client. See [the link](https://docs.aws.amazon.com/AmazonS3/latest/dev/ServerSideEncryptionCustomerKeys.html). Closes [#19428](https://github.com/ClickHouse/ClickHouse/issues/19428). [#19748](https://github.com/ClickHouse/ClickHouse/pull/19748) ([Vladimir Chebotarev](https://github.com/excitoon)).
* Added `implicit_key` option for `executable` dictionary source. It allows to avoid printing key for every record if records comes in the same order as the input keys. Implements [#14527](https://github.com/ClickHouse/ClickHouse/issues/14527). [#19677](https://github.com/ClickHouse/ClickHouse/pull/19677) ([Maksim Kita](https://github.com/kitaisreal)).
* Add quota type `query_selects` and `query_inserts`. [#19603](https://github.com/ClickHouse/ClickHouse/pull/19603) ([JackyWoo](https://github.com/JackyWoo)).
* Add function `extractTextFromHTML` [#19600](https://github.com/ClickHouse/ClickHouse/pull/19600) ([zlx19950903](https://github.com/zlx19950903)), ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Tables with `MergeTree*` engine now have two new table-level settings for query concurrency control. Setting `max_concurrent_queries` limits the number of concurrently executed queries which are related to this table. Setting `min_marks_to_honor_max_concurrent_queries` tells to apply previous setting only if query reads at least this number of marks. [#19544](https://github.com/ClickHouse/ClickHouse/pull/19544) ([Amos Bird](https://github.com/amosbird)).
* Added `file` function to read file from user_files directory as a String. This is different from the `file` table function. This implements [#issue:18851](https://github.com/ClickHouse/ClickHouse/issues/18851). [#19204](https://github.com/ClickHouse/ClickHouse/pull/19204) ([keenwolf](https://github.com/keen-wolf)).
#### Experimental feature
* 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_window_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)).
* Add the ability to backup/restore metadata files for DiskS3. [#18377](https://github.com/ClickHouse/ClickHouse/pull/18377) ([Pavel Kovalenko](https://github.com/Jokser)).
#### Performance Improvement
* Hedged requests for remote queries. When setting `use_hedged_requests` enabled (off by default), allow to establish many connections with different replicas for query. New connection is enabled in case existent connection(s) with replica(s) were not established within `hedged_connection_timeout` or no data was received within `receive_data_timeout`. Query uses the first connection which send non empty progress packet (or data packet, if `allow_changing_replica_until_first_data_packet`); other connections are cancelled. Queries with `max_parallel_replicas > 1` are supported. [#19291](https://github.com/ClickHouse/ClickHouse/pull/19291) ([Kruglov Pavel](https://github.com/Avogar)). This allows to significantly reduce tail latencies on very large clusters.
* Added support for `PREWHERE` (and enable the corresponding optimization) when tables have row-level security expressions specified. [#19576](https://github.com/ClickHouse/ClickHouse/pull/19576) ([Denis Glazachev](https://github.com/traceon)).
* The setting `distributed_aggregation_memory_efficient` is enabled by default. It will lower memory usage and improve performance of distributed queries. [#20599](https://github.com/ClickHouse/ClickHouse/pull/20599) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Improve performance of GROUP BY multiple fixed size keys. [#20472](https://github.com/ClickHouse/ClickHouse/pull/20472) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Improve performance of aggregate functions by more strict aliasing. [#19946](https://github.com/ClickHouse/ClickHouse/pull/19946) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Speed up reading from `Memory` tables in extreme cases (when reading speed is in order of 50 GB/sec) by simplification of pipeline and (consequently) less lock contention in pipeline scheduling. [#20468](https://github.com/ClickHouse/ClickHouse/pull/20468) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Partially reimplement HTTP server to make it making less copies of incoming and outgoing data. It gives up to 1.5 performance improvement on inserting long records over HTTP. [#19516](https://github.com/ClickHouse/ClickHouse/pull/19516) ([Ivan](https://github.com/abyss7)).
* Add `compress` setting for `Memory` tables. If it's enabled the table will use less RAM. On some machines and datasets it can also work faster on SELECT, but it is not always the case. This closes [#20093](https://github.com/ClickHouse/ClickHouse/issues/20093). Note: there are reasons why Memory tables can work slower than MergeTree: (1) lack of compression (2) static size of blocks (3) lack of indices and prewhere... [#20168](https://github.com/ClickHouse/ClickHouse/pull/20168) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Slightly better code in aggregation. [#20978](https://github.com/ClickHouse/ClickHouse/pull/20978) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Add back `intDiv`/`modulo` specializations for better performance. This fixes [#21293](https://github.com/ClickHouse/ClickHouse/issues/21293) . The regression was introduced in https://github.com/ClickHouse/ClickHouse/pull/18145 . [#21307](https://github.com/ClickHouse/ClickHouse/pull/21307) ([Amos Bird](https://github.com/amosbird)).
* Do not squash blocks too much on INSERT SELECT if inserting into Memory table. In previous versions inefficient data representation was created in Memory table after INSERT SELECT. This closes [#13052](https://github.com/ClickHouse/ClickHouse/issues/13052). [#20169](https://github.com/ClickHouse/ClickHouse/pull/20169) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Fix at least one case when DataType parser may have exponential complexity (found by fuzzer). This closes [#20096](https://github.com/ClickHouse/ClickHouse/issues/20096). [#20132](https://github.com/ClickHouse/ClickHouse/pull/20132) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Parallelize SELECT with FINAL for single part with level > 0 when `do_not_merge_across_partitions_select_final` setting is 1. [#19375](https://github.com/ClickHouse/ClickHouse/pull/19375) ([Kruglov Pavel](https://github.com/Avogar)).
* Fill only requested columns when querying `system.parts` and `system.parts_columns`. Closes [#19570](https://github.com/ClickHouse/ClickHouse/issues/19570). [#21035](https://github.com/ClickHouse/ClickHouse/pull/21035) ([Anmol Arora](https://github.com/anmolarora)).
* Perform algebraic optimizations of arithmetic expressions inside `avg` aggregate function. close [#20092](https://github.com/ClickHouse/ClickHouse/issues/20092). [#20183](https://github.com/ClickHouse/ClickHouse/pull/20183) ([flynn](https://github.com/ucasFL)).
#### Improvement
* Case-insensitive compression methods for table functions. Also fixed LZMA compression method which was checked in upper case. [#21416](https://github.com/ClickHouse/ClickHouse/pull/21416) ([Vladimir Chebotarev](https://github.com/excitoon)).
* Add two settings to delay or throw error during insertion when there are too many inactive parts. This is useful when server fails to clean up parts quickly enough. [#20178](https://github.com/ClickHouse/ClickHouse/pull/20178) ([Amos Bird](https://github.com/amosbird)).
* Provide better compatibility for mysql clients. 1. mysql jdbc 2. mycli. [#21367](https://github.com/ClickHouse/ClickHouse/pull/21367) ([Amos Bird](https://github.com/amosbird)).
* Forbid to drop a column if it's referenced by materialized view. Closes [#21164](https://github.com/ClickHouse/ClickHouse/issues/21164). [#21303](https://github.com/ClickHouse/ClickHouse/pull/21303) ([flynn](https://github.com/ucasFL)).
* MySQL dictionary source will now retry unexpected connection failures (Lost connection to MySQL server during query) which sometimes happen on SSL/TLS connections. [#21237](https://github.com/ClickHouse/ClickHouse/pull/21237) ([Alexander Kazakov](https://github.com/Akazz)).
* Usability improvement: more consistent `DateTime64` parsing: recognize the case when unix timestamp with subsecond resolution is specified as scaled integer (like `1111111111222` instead of `1111111111.222`). This closes [#13194](https://github.com/ClickHouse/ClickHouse/issues/13194). [#21053](https://github.com/ClickHouse/ClickHouse/pull/21053) ([alexey-milovidov](https://github.com/alexey-milovidov)).

* If user calls `JSONExtract` function with `Float32` type requested, allow inaccurate conversion to the result type. For example the number `0.1` in JSON is double precision and is not representable in Float32, but the user still wants to get it. Previous versions return 0 for non-Nullable type and NULL for Nullable type to indicate that conversion is imprecise. The logic was 100% correct but it was surprising to users and leading to questions. This closes [#13962](https://github.com/ClickHouse/ClickHouse/issues/13962).

/** Custom memcpy implementation for ClickHouse.
* It has the following benefits over using glibc's implementation:
* 1. Avoiding dependency on specific version of glibc's symbol, like memcpy@@GLIBC_2.14 for portability.
* 2. Avoiding indirect call via PLT due to shared linking, that can be less efficient.
* 3. It's possible to include this header and call inline_memcpy directly for better inlining or interprocedural analysis.
* 4. Better results on our performance tests on current CPUs: up to 25% on some queries and up to 0.7%..1% in average across all queries.
*
* Writing our own memcpy is extremely difficult for the following reasons:
* 1. The optimal variant depends on the specific CPU model.
* 2. The optimal variant depends on the distribution of size arguments.
* 3. It depends on the number of threads copying data concurrently.
* 4. It also depends on how the calling code is using the copied data and how the different memcpy calls are related to each other.
* Due to vast range of scenarios it makes proper testing especially difficult.
* When writing our own memcpy there is a risk to overoptimize it
* on non-representative microbenchmarks while making real-world use cases actually worse.
*
* Most of the benchmarks for memcpy on the internet are wrong.
*
* Let's look at the details:
*
* For small size, the order of branches in code is important.
* There are variants with specific order of branches (like here or in glibc)
* or with jump table (in asm code see example from Cosmopolitan libc:
* https://github.com/jart/cosmopolitan/blob/de09bec215675e9b0beb722df89c6f794da74f3f/libc/nexgen32e/memcpy.S#L61)
* or with Duff device in C (see https://github.com/skywind3000/FastMemcpy/)
*
* It's also important how to copy uneven sizes.
* Almost every implementation, including this, is using two overlapping movs.
*
* It is important to disable -ftree-loop-distribute-patterns when compiling memcpy implementation,
* otherwise the compiler can replace internal loops to a call to memcpy that will lead to infinite recursion.
*
* For larger sizes it's important to choose the instructions used:
* - SSE or AVX or AVX-512;
* - rep movsb;
* Performance will depend on the size threshold, on the CPU model, on the "erms" flag
* ("Enhansed Rep MovS" - it indicates that performance of "rep movsb" is decent for large sizes)
* https://stackoverflow.com/questions/43343231/enhanced-rep-movsb-for-memcpy
*
* Using AVX-512 can be bad due to throttling.
* Using AVX can be bad if most code is using SSE due to switching penalty
* (it also depends on the usage of "vzeroupper" instruction).
* But in some cases AVX gives a win.
*
* It also depends on how many times the loop will be unrolled.
* We are unrolling the loop 8 times (by the number of available registers), but it not always the best.
*
* It also depends on the usage of aligned or unaligned loads/stores.
* We are using unaligned loads and aligned stores.
*
* It also depends on the usage of prefetch instructions. It makes sense on some Intel CPUs but can slow down performance on AMD.
* Setting up correct offset for prefetching is non-obvious.
*
* Non-temporary (cache bypassing) stores can be used for very large sizes (more than a half of L3 cache).
* But the exact threshold is unclear - when doing memcpy from multiple threads the optimal threshold can be lower,
* because L3 cache is shared (and L2 cache is partially shared).
*
* Very large size of memcpy typically indicates suboptimal (not cache friendly) algorithms in code or unrealistic scenarios,
* so we don't pay attention to using non-temporary stores.
*
* On recent Intel CPUs, the presence of "erms" makes "rep movsb" the most benefitial,
* even comparing to non-temporary aligned unrolled stores even with the most wide registers.
*
* memcpy can be written in asm, C or C++. The latter can also use inline asm.
* The asm implementation can be better to make sure that compiler won't make the code worse,
* to ensure the order of branches, the code layout, the usage of all required registers.
* But if it is located in separate translation unit, inlining will not be possible
* (inline asm can be used to overcome this limitation).
* Sometimes C or C++ code can be further optimized by compiler.
* For example, clang is capable replacing SSE intrinsics to AVX code if -mavx is used.
*
* Please note that compiler can replace plain code to memcpy and vice versa.
* - memcpy with compile-time known small size is replaced to simple instructions without a call to memcpy;
* it is controlled by -fbuiltin-memcpy and can be manually ensured by calling __builtin_memcpy.
* This is often used to implement unaligned load/store without undefined behaviour in C++.
* - a loop with copying bytes can be recognized and replaced by a call to memcpy;
* it is controlled by -ftree-loop-distribute-patterns.
* - also note that a loop with copying bytes can be unrolled, peeled and vectorized that will give you
* inline code somewhat similar to a decent implementation of memcpy.
*
* This description is up to date as of Mar 2021.
*
* How to test the memcpy implementation for performance:
* 1. Test on real production workload.
* 2. For synthetic test, see utils/memcpy-bench, but make sure you will do the best to exhaust the wide range of scenarios.
*
* TODO: Add self-tuning memcpy with bayesian bandits algorithm for large sizes.
* See https://habr.com/en/company/yandex/blog/457612/

Internal implementation of `memcpy` function.
It has the following advantages over `libc`-supplied implementation:
- it is linked statically, so the function is called directly, not through a `PLT` (procedure lookup table of shared library);
- it is linked statically, so the function can have position-dependent code;
- your binaries will not depend on `glibc`'s memcpy, that forces dependency on specific symbol version like `memcpy@@GLIBC_2.14` and consequently on specific version of `glibc` library;
- you can include `memcpy.h` directly and the function has the chance to be inlined, which is beneficial for small but unknown at compile time sizes of memory regions;
- this version of `memcpy` pretend to be faster (in our benchmarks, the difference is within few percents).
Currently it uses the implementation from **Linwei** (skywind3000@163.com).
Look at https://www.zhihu.com/question/35172305 for discussion.
Drawbacks:
- only use SSE 2, doesn't use wider (AVX, AVX 512) vector registers when available;
- no CPU dispatching; doesn't take into account actual cache size.
Also worth to look at:
- simple implementation from Facebook: https://github.com/facebook/folly/blob/master/folly/memcpy.S
- implementation from Agner Fog: http://www.agner.org/optimize/
- glibc source code.
