## 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)).
* Fix uncaught exception in `InterserverIOHTTPHandler`. [#22146](https://github.com/ClickHouse/ClickHouse/pull/22146) ([Azat Khuzhin](https://github.com/azat)).
* Fix docker entrypoint in case `http_port` is not in the config. [#22132](https://github.com/ClickHouse/ClickHouse/pull/22132) ([Ewout](https://github.com/devwout)).

* 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`.

On Ubuntu/Debian you can use the automatic installation script (check [official webpage](https://apt.llvm.org/))
```bash
```bash
sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"
```
For other Linux distribution - check the availability of the [prebuild packages](https://releases.llvm.org/download.html) or build clang [from sources](https://clang.llvm.org/get_started.html).

### Install GCC 10 {#install-gcc-10}
We recommend building ClickHouse with clang-11, GCC-10 also supported, but it is not used for production builds.
If you want to use GCC-10 there are several ways to install it.
#### Install from Repository {#install-from-repository}
On Ubuntu 19.10 or newer:
$ sudo apt-get update
$ sudo apt-get install gcc-10 g++-10
#### Install from a PPA Package {#install-from-a-ppa-package}
On older Ubuntu:
``` 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
```
#### Install from Sources {#install-from-sources}
See [utils/ci/build-gcc-from-sources.sh](https://github.com/ClickHouse/ClickHouse/blob/master/utils/ci/build-gcc-from-sources.sh)
#### Use GCC 10 for Builds {#use-gcc-10-for-builds}
``` bash
$ export CC=gcc-10
$ export CXX=g++-10

# Atomic {#atomic}
It supports non-blocking `DROP` and `RENAME TABLE` queries and atomic `EXCHANGE TABLES t1 AND t2` queries. `Atomic` database engine is used by default.
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.
## Creating a Database {#creating-a-database}
```sql
CREATE DATABASE test ENGINE = Atomic;
``` sql
CREATE DATABASE test[ ENGINE = Atomic];
```
[Original article](https://clickhouse.tech/docs/en/engines/database-engines/atomic/) <!--hide-->
## 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 is recomended do not specify parameters of engine - path in ZooKeeper and replica name. In this case will be used parameters of the configuration [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 specify parameters of engine explicitly than recomended to use {uuid} macros. This is useful so that unique paths are automatically generated for each table in the ZooKeeper.
