### ClickHouse release v21.9, 2021-09-09
|
||||
|
||||
#### Backward Incompatible Change
|
||||
|
||||
* Do not output trailing zeros in text representation of `Decimal` types. Example: `1.23` will be printed instead of `1.230000` for decimal with scale 6. This closes [#15794](https://github.com/ClickHouse/ClickHouse/issues/15794). It may introduce slight incompatibility if your applications somehow relied on the trailing zeros. Serialization in output formats can be controlled with the setting `output_format_decimal_trailing_zeros`. Implementation of `toString` and casting to String is changed unconditionally. [#27680](https://github.com/ClickHouse/ClickHouse/pull/27680) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Do not allow to apply parametric aggregate function with `-Merge` combinator to aggregate function state if state was produced by aggregate function with different parameters. For example, state of `fooState(42)(x)` cannot be finalized with `fooMerge(s)` or `fooMerge(123)(s)`, parameters must be specified explicitly like `fooMerge(42)(s)` and must be equal. It does not affect some special aggregate functions like `quantile` and `sequence*` that use parameters for finalization only. [#26847](https://github.com/ClickHouse/ClickHouse/pull/26847) ([tavplubix](https://github.com/tavplubix)).
|
||||
* Under clickhouse-local, always treat local addresses with a port as remote. [#26736](https://github.com/ClickHouse/ClickHouse/pull/26736) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Fix the issue that in case of some sophisticated query with column aliases identical to the names of expressions, bad cast may happen. This fixes [#25447](https://github.com/ClickHouse/ClickHouse/issues/25447). This fixes [#26914](https://github.com/ClickHouse/ClickHouse/issues/26914). This fix may introduce backward incompatibility: if there are different expressions with identical names, exception will be thrown. It may break some rare cases when `enable_optimize_predicate_expression` is set. [#26639](https://github.com/ClickHouse/ClickHouse/pull/26639) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Now, scalar subquery always returns `Nullable` result if it's type can be `Nullable`. It is needed because in case of empty subquery it's result should be `Null`. Previously, it was possible to get error about incompatible types (type deduction does not execute scalar subquery, and it could use not-nullable type). Scalar subquery with empty result which can't be converted to `Nullable` (like `Array` or `Tuple`) now throws error. Fixes [#25411](https://github.com/ClickHouse/ClickHouse/issues/25411). [#26423](https://github.com/ClickHouse/ClickHouse/pull/26423) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||

|
||||
* When client connects to server, it receives information about all warnings that are already were collected by server. (It can be disabled by using option `--no-warnings`).

|
||||
|
||||
#### Experimental Feature
|
||||
|
||||
* Added a compression codec `AES_128_GCM_SIV` which encrypts columns instead of compressing them. [#19896](https://github.com/ClickHouse/ClickHouse/pull/19896) ([PHO](https://github.com/depressed-pho)). Will be rewritten, do not use.
|
||||
* Rename `MaterializeMySQL` to `MaterializedMySQL`. [#26822](https://github.com/ClickHouse/ClickHouse/pull/26822) ([tavplubix](https://github.com/tavplubix)).
|
||||
|
||||
#### Performance Improvement
|
||||
|
||||
* Improve the performance of fast queries when `max_execution_time = 0` by reducing the number of `clock_gettime` system calls. [#27325](https://github.com/ClickHouse/ClickHouse/pull/27325) ([filimonov](https://github.com/filimonov)).
|
||||
* Specialize date time related comparison to achieve better performance. This fixes [#27083](https://github.com/ClickHouse/ClickHouse/issues/27083) . [#27122](https://github.com/ClickHouse/ClickHouse/pull/27122) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Share file descriptors in concurrent reads of the same files. There is no noticeable performance difference on Linux. But the number of opened files will be significantly (10..100 times) lower on typical servers and it makes operations easier. See [#26214](https://github.com/ClickHouse/ClickHouse/issues/26214). [#26768](https://github.com/ClickHouse/ClickHouse/pull/26768) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Improve latency of short queries, that require reading from tables with large number of columns. [#26371](https://github.com/ClickHouse/ClickHouse/pull/26371) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Don't build sets for indices when analyzing a query. [#26365](https://github.com/ClickHouse/ClickHouse/pull/26365) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Vectorize the SUM of Nullable integer types with native representation ([David Manzanares](https://github.com/davidmanzanares), [Raúl Marín](https://github.com/Algunenano)). [#26248](https://github.com/ClickHouse/ClickHouse/pull/26248) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Compile expressions involving columns with `Enum` types. [#26237](https://github.com/ClickHouse/ClickHouse/pull/26237) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Compile aggregate functions `groupBitOr`, `groupBitAnd`, `groupBitXor`. [#26161](https://github.com/ClickHouse/ClickHouse/pull/26161) ([Maksim Kita](https://github.com/kitaisreal)).

|
||||
* Reduce memory usage and number of read rows in queries with `ORDER BY primary_key`. [#25721](https://github.com/ClickHouse/ClickHouse/pull/25721) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Enable `distributed_push_down_limit` by default. [#27104](https://github.com/ClickHouse/ClickHouse/pull/27104) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Make `toTimeZone` monotonicity when timeZone is a constant value to support partition puring when use sql like:. [#26261](https://github.com/ClickHouse/ClickHouse/pull/26261) ([huangzhaowei](https://github.com/SaintBacchus)).
|
||||
|
||||
#### Improvement
|
||||
|
||||
* Mark window functions as ready for general use. Remove the `allow_experimental_window_functions` setting. [#27184](https://github.com/ClickHouse/ClickHouse/pull/27184) ([Alexander Kuzmenkov](https://github.com/akuzm)).
|
||||
* Improve compatibility with non-whole-minute timezone offsets. [#27080](https://github.com/ClickHouse/ClickHouse/pull/27080) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* If file descriptor in `File` table is regular file - allow to read multiple times from it. It allows `clickhouse-local` to read multiple times from stdin (with multiple SELECT queries or subqueries) if stdin is a regular file like `clickhouse-local --query "SELECT * FROM table UNION ALL SELECT * FROM table" ... < file`. This closes [#11124](https://github.com/ClickHouse/ClickHouse/issues/11124). Co-authored with ([alexey-milovidov](https://github.com/alexey-milovidov)). [#25960](https://github.com/ClickHouse/ClickHouse/pull/25960) ([BoloniniD](https://github.com/BoloniniD)).
|
||||
* Remove duplicate index analysis and avoid possible invalid limit checks during projection analysis. [#27742](https://github.com/ClickHouse/ClickHouse/pull/27742) ([Amos Bird](https://github.com/amosbird)).

* Disallow `arrayJoin` on partition expressions. [#27648](https://github.com/ClickHouse/ClickHouse/pull/27648) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Log client IP address if authentication fails. [#27514](https://github.com/ClickHouse/ClickHouse/pull/27514) ([Misko Lee](https://github.com/imiskolee)).
|
||||
* Use bytes instead of strings for binary data in the GRPC protocol. [#27431](https://github.com/ClickHouse/ClickHouse/pull/27431) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Send response with error message if HTTP port is not set and user tries to send HTTP request to TCP port. [#27385](https://github.com/ClickHouse/ClickHouse/pull/27385) ([Braulio Valdivielso Martínez](https://github.com/BraulioVM)).
|
||||
* Add `_CAST` function for internal usage, which will not preserve type nullability, but non-internal cast will preserve according to setting `cast_keep_nullable`. Closes [#12636](https://github.com/ClickHouse/ClickHouse/issues/12636). [#27382](https://github.com/ClickHouse/ClickHouse/pull/27382) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Add setting `log_formatted_queries` to log additional formatted query into `system.query_log`. It's useful for normalized query analysis because functions like `normalizeQuery` and `normalizeQueryKeepNames` don't parse/format queries in order to achieve better performance. [#27380](https://github.com/ClickHouse/ClickHouse/pull/27380) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Add two settings `max_hyperscan_regexp_length` and `max_hyperscan_regexp_total_length` to prevent huge regexp being used in hyperscan related functions, such as `multiMatchAny`. [#27378](https://github.com/ClickHouse/ClickHouse/pull/27378) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Memory consumed by bitmap aggregate functions now is taken into account for memory limits. This closes [#26555](https://github.com/ClickHouse/ClickHouse/issues/26555). [#27252](https://github.com/ClickHouse/ClickHouse/pull/27252) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Add new index data skipping minmax index format for proper Nullable support. [#27250](https://github.com/ClickHouse/ClickHouse/pull/27250) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Add 10 seconds cache for S3 proxy resolver. [#27216](https://github.com/ClickHouse/ClickHouse/pull/27216) ([ianton-ru](https://github.com/ianton-ru)).
|
||||
* Split global mutex into individual regexp construction. This helps avoid huge regexp construction blocking other related threads. [#27211](https://github.com/ClickHouse/ClickHouse/pull/27211) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Support schema for PostgreSQL database engine. Closes [#27166](https://github.com/ClickHouse/ClickHouse/issues/27166). [#27198](https://github.com/ClickHouse/ClickHouse/pull/27198) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Track memory usage in clickhouse-client. [#27191](https://github.com/ClickHouse/ClickHouse/pull/27191) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
* Try recording `query_kind` in `system.query_log` even when query fails to start. [#27182](https://github.com/ClickHouse/ClickHouse/pull/27182) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Added columns `replica_is_active` that maps replica name to is replica active status to table `system.replicas`. Closes [#27138](https://github.com/ClickHouse/ClickHouse/issues/27138). [#27180](https://github.com/ClickHouse/ClickHouse/pull/27180) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Allow to pass query settings via server URI in Web UI. [#27177](https://github.com/ClickHouse/ClickHouse/pull/27177) ([kolsys](https://github.com/kolsys)).
|
||||
* Add a new metric called `MaxPushedDDLEntryID` which is the maximum ddl entry id that current node push to zookeeper. [#27174](https://github.com/ClickHouse/ClickHouse/pull/27174) ([Fuwang Hu](https://github.com/fuwhu)).
|
||||
* Improved the existence condition judgment and empty string node judgment when `clickhouse-keeper` creates znode. [#27125](https://github.com/ClickHouse/ClickHouse/pull/27125) ([小路](https://github.com/nicelulu)).
|
||||
* Merge JOIN correctly handles empty set in the right. [#27078](https://github.com/ClickHouse/ClickHouse/pull/27078) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Now functions can be shard-level constants, which means if it's executed in the context of some distributed table, it generates a normal column, otherwise it produces a constant value. Notable functions are: `hostName()`, `tcpPort()`, `version()`, `buildId()`, `uptime()`, etc. [#27020](https://github.com/ClickHouse/ClickHouse/pull/27020) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Updated `extractAllGroupsHorizontal` - upper limit on the number of matches per row can be set via optional third argument. [#26961](https://github.com/ClickHouse/ClickHouse/pull/26961) ([Vasily Nemkov](https://github.com/Enmk)).
|
||||
* Expose `RocksDB` statistics via system.rocksdb table. Read rocksdb options from ClickHouse config (`rocksdb...` keys). NOTE: ClickHouse does not rely on RocksDB, it is just one of the additional integration storage engines. [#26821](https://github.com/ClickHouse/ClickHouse/pull/26821) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Less verbose internal RocksDB logs. NOTE: ClickHouse does not rely on RocksDB, it is just one of the additional integration storage engines. This closes [#26252](https://github.com/ClickHouse/ClickHouse/issues/26252). [#26789](https://github.com/ClickHouse/ClickHouse/pull/26789) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||

|
||||
* Avoid hanging `clickhouse-benchmark` if connection fails (i.e. on EMFILE). [#26656](https://github.com/ClickHouse/ClickHouse/pull/26656) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Allow more threads to be used by the Kafka engine. [#26642](https://github.com/ClickHouse/ClickHouse/pull/26642) ([feihengye](https://github.com/feihengye)).
|
||||
* Add round-robin support for `clickhouse-benchmark` (it does not differ from the regular multi host/port run except for statistics report). [#26607](https://github.com/ClickHouse/ClickHouse/pull/26607) ([Azat Khuzhin](https://github.com/azat)).

* Set client query kind for `mysql` and `postgresql` compatibility protocol handlers. [#26498](https://github.com/ClickHouse/ClickHouse/pull/26498) ([anneji-dev](https://github.com/anneji-dev)).
|
||||
* Apply `LIMIT` on the shards for queries like `SELECT * FROM dist ORDER BY key LIMIT 10` w/ `distributed_push_down_limit=1`. Avoid running `Distinct`/`LIMIT BY` steps for queries like `SELECT DISTINCT shading_key FROM dist ORDER BY key`. Now `distributed_push_down_limit` is respected by `optimize_distributed_group_by_sharding_key` optimization. [#26466](https://github.com/ClickHouse/ClickHouse/pull/26466) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Updated protobuf to 3.17.3. Changelogs are available on https://github.com/protocolbuffers/protobuf/releases. [#26424](https://github.com/ClickHouse/ClickHouse/pull/26424) ([Ilya Yatsishin](https://github.com/qoega)).

|
||||
* Improve behaviour with non-existing host in user allowed host list. [#26368](https://github.com/ClickHouse/ClickHouse/pull/26368) ([ianton-ru](https://github.com/ianton-ru)).
|
||||
* Add ability to set `Distributed` directory monitor settings via CREATE TABLE (i.e. `CREATE TABLE dist (key Int) Engine=Distributed(cluster, db, table) SETTINGS monitor_batch_inserts=1` and similar). [#26336](https://github.com/ClickHouse/ClickHouse/pull/26336) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Save server address in history URLs in web UI if it differs from the origin of web UI. This closes [#26044](https://github.com/ClickHouse/ClickHouse/issues/26044). [#26322](https://github.com/ClickHouse/ClickHouse/pull/26322) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Add events to profile calls to `sleep` / `sleepEachRow`. [#26320](https://github.com/ClickHouse/ClickHouse/pull/26320) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Allow to reuse connections of shards among different clusters. It also avoids creating new connections when using `cluster` table function. [#26318](https://github.com/ClickHouse/ClickHouse/pull/26318) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Control the execution period of clear old temporary directories by parameter with default value. [#26212](https://github.com/ClickHouse/ClickHouse/issues/26212). [#26313](https://github.com/ClickHouse/ClickHouse/pull/26313) ([fastio](https://github.com/fastio)).
|
||||
* Add a setting `function_range_max_elements_in_block` to tune the safety threshold for data volume generated by function `range`. This closes [#26303](https://github.com/ClickHouse/ClickHouse/issues/26303). [#26305](https://github.com/ClickHouse/ClickHouse/pull/26305) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Check hash function at table creation, not at sampling. Add settings for MergeTree, if someone create a table with incorrect sampling column but sampling never be used, disable this settings for starting the server without exception. [#26256](https://github.com/ClickHouse/ClickHouse/pull/26256) ([zhaoyu](https://github.com/zxc111)).
|
||||
* Added `output_format_avro_string_column_pattern` setting to put specified String columns to Avro as string instead of default bytes. Implements [#22414](https://github.com/ClickHouse/ClickHouse/issues/22414). [#26245](https://github.com/ClickHouse/ClickHouse/pull/26245) ([Ilya Golshtein](https://github.com/ilejn)).
|
||||
* Add information about column sizes in `system.columns` table for `Log` and `TinyLog` tables. This closes [#9001](https://github.com/ClickHouse/ClickHouse/issues/9001). [#26241](https://github.com/ClickHouse/ClickHouse/pull/26241) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Don't throw exception when querying `system.detached_parts` table if there is custom disk configuration and `detached` directory does not exist on some disks. This closes [#26078](https://github.com/ClickHouse/ClickHouse/issues/26078). [#26236](https://github.com/ClickHouse/ClickHouse/pull/26236) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Check for non-deterministic functions in keys, including constant expressions like `now()`, `today()`. This closes [#25875](https://github.com/ClickHouse/ClickHouse/issues/25875). This closes [#11333](https://github.com/ClickHouse/ClickHouse/issues/11333). [#26235](https://github.com/ClickHouse/ClickHouse/pull/26235) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* convert timestamp and timestamptz data types to `DateTime64` in PostgreSQL table engine. [#26234](https://github.com/ClickHouse/ClickHouse/pull/26234) ([jasine](https://github.com/jasine)).
|
||||
* Apply aggressive IN index analysis for projections so that better projection candidate can be selected. [#26218](https://github.com/ClickHouse/ClickHouse/pull/26218) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Remove GLOBAL keyword for IN when scalar function is passed. In previous versions, if user specified `GLOBAL IN f(x)` exception was thrown. [#26217](https://github.com/ClickHouse/ClickHouse/pull/26217) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Add error id (like `BAD_ARGUMENTS`) to exception messages. This closes [#25862](https://github.com/ClickHouse/ClickHouse/issues/25862). [#26172](https://github.com/ClickHouse/ClickHouse/pull/26172) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Fix incorrect output with --progress option for clickhouse-local. Progress bar will be cleared once it gets to 100% - same as it is done for clickhouse-client. Closes [#17484](https://github.com/ClickHouse/ClickHouse/issues/17484). [#26128](https://github.com/ClickHouse/ClickHouse/pull/26128) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Add `merge_selecting_sleep_ms` setting. [#26120](https://github.com/ClickHouse/ClickHouse/pull/26120) ([lthaooo](https://github.com/lthaooo)).
|
||||
* Remove complicated usage of Linux AIO with one block readahead and replace it with plain simple synchronous IO with O_DIRECT. In previous versions, the setting `min_bytes_to_use_direct_io` may not work correctly if `max_threads` is greater than one. Reading with direct IO (that is disabled by default for queries and enabled by default for large merges) will work in less efficient way. This closes [#25997](https://github.com/ClickHouse/ClickHouse/issues/25997). [#26003](https://github.com/ClickHouse/ClickHouse/pull/26003) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Flush `Distributed` table on `REPLACE TABLE` query. Resolves [#24566](https://github.com/ClickHouse/ClickHouse/issues/24566) - Do not replace (or create) table on `[CREATE OR] REPLACE TABLE ...

|
||||
* Add `views` column to system.query_log containing the names of the (materialized or live) views executed by the query. Adds a new log table (`system.query_views_log`) that contains information about each view executed during a query. Modifies view execution: When an exception is thrown while executing a view, any view that has already startedwill continue running until it finishes. This used to be the behaviour under parallel_view_processing=true and now it's always the same behaviour. - Dependent views now report reading progress to the context. [#25714](https://github.com/ClickHouse/ClickHouse/pull/25714) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Do connection draining asynchonously upon finishing executing distributed queries. A new server setting is added `max_threads_for_connection_collector` which specifies the number of workers to recycle connections in background. If the pool is full, connection will be drained synchronously but a bit different than before: It's drained after we send EOS to client, query will succeed immediately after receiving enough data, and any exception will be logged instead of throwing to the client. Added setting `drain_timeout` (3 seconds by default). Connection draining will disconnect upon timeout. [#25674](https://github.com/ClickHouse/ClickHouse/pull/25674) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Support for multiple includes in configuration. It is possible to include users configuration, remote servers configuration from multiple sources. Simply place `<include />` element with `from_zk`, `from_env` or `incl` attribute and it will be replaced with the substitution. [#24404](https://github.com/ClickHouse/ClickHouse/pull/24404) ([nvartolomei](https://github.com/nvartolomei)).
|
||||
* Fix multiple block insertion into distributed table with `insert_distributed_one_random_shard = 1`. This is a marginal feature. Mark as improvement. [#23140](https://github.com/ClickHouse/ClickHouse/pull/23140) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Support `LowCardinality` and `FixedString` keys/values for `Map` type. [#21543](https://github.com/ClickHouse/ClickHouse/pull/21543) ([hexiaoting](https://github.com/hexiaoting)).
|
||||
* Enable reloading of local disk config. [#19526](https://github.com/ClickHouse/ClickHouse/pull/19526) ([taiyang-li](https://github.com/taiyang-li)).
|
||||
* Now KeyConditions can correctly skip nullable keys, including `isNull` and `isNotNull`. https://github.com/ClickHouse/ClickHouse/pull/12433. [#12455](https://github.com/ClickHouse/ClickHouse/pull/12455) ([Amos Bird](https://github.com/amosbird)).

* Fix potential crash if more than one `untuple` expression is used. [#26179](https://github.com/ClickHouse/ClickHouse/pull/26179) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Don't throw exception in `toString` for Nullable Enum if Enum does not have a value for zero, close [#25806](https://github.com/ClickHouse/ClickHouse/issues/25806). [#26123](https://github.com/ClickHouse/ClickHouse/pull/26123) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Fixed incorrect `sequence_id` in MySQL protocol packets that ClickHouse sends on exception during query execution. It might cause MySQL client to reset connection to ClickHouse server. Fixes [#21184](https://github.com/ClickHouse/ClickHouse/issues/21184). [#26051](https://github.com/ClickHouse/ClickHouse/pull/26051) ([tavplubix](https://github.com/tavplubix)).
|
||||
* Fix for the case that `cutToFirstSignificantSubdomainCustom()`/`cutToFirstSignificantSubdomainCustomWithWWW()`/`firstSignificantSubdomainCustom()` returns incorrect type for consts, and hence `optimize_skip_unused_shards` does not work:. [#26041](https://github.com/ClickHouse/ClickHouse/pull/26041) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fix possible mismatched header when using normal projection with prewhere. This fixes [#26020](https://github.com/ClickHouse/ClickHouse/issues/26020). [#26038](https://github.com/ClickHouse/ClickHouse/pull/26038) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Fix sharding_key from column w/o function for remote() (before `select * from remote('127.1', system.one, dummy)` leads to `Unknown column: dummy, there are only columns .` error). [#25824](https://github.com/ClickHouse/ClickHouse/pull/25824) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fixed `Not found column ...` and `Missing column ...` errors when selecting from `MaterializeMySQL`. Fixes [#23708](https://github.com/ClickHouse/ClickHouse/issues/23708), [#24830](https://github.com/ClickHouse/ClickHouse/issues/24830), [#25794](https://github.com/ClickHouse/ClickHouse/issues/25794). [#25822](https://github.com/ClickHouse/ClickHouse/pull/25822) ([tavplubix](https://github.com/tavplubix)).
|
||||
* Fix `optimize_skip_unused_shards_rewrite_in` for non-UInt64 types (may select incorrect shards eventually or throw `Cannot infer type of an empty tuple` or `Function tuple requires at least one argument`). [#25798](https://github.com/ClickHouse/ClickHouse/pull/25798) ([Azat Khuzhin](https://github.com/azat)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|
||||
|
||||
* Now we ran stateful and stateless tests in random timezones. Fixes [#12439](https://github.com/ClickHouse/ClickHouse/issues/12439). Reading String as DateTime and writing DateTime as String in Protobuf format now respect timezone. Reading UInt16 as DateTime in Arrow and Parquet formats now treat it as Date and then converts to DateTime with respect to DateTime's timezone, because Date is serialized in Arrow and Parquet as UInt16. GraphiteMergeTree now respect time zone for rounding of times. Fixes [#5098](https://github.com/ClickHouse/ClickHouse/issues/5098). Author: @alexey-milovidov. [#15408](https://github.com/ClickHouse/ClickHouse/pull/15408) ([alesapin](https://github.com/alesapin)).
|
||||
* `clickhouse-test` supports SQL tests with [Jinja2](https://jinja.palletsprojects.com/en/3.0.x/templates/#synopsis) templates. [#26579](https://github.com/ClickHouse/ClickHouse/pull/26579) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Add support for build with `clang-13`. This closes [#27705](https://github.com/ClickHouse/ClickHouse/issues/27705). [#27714](https://github.com/ClickHouse/ClickHouse/pull/27714) ([alexey-milovidov](https://github.com/alexey-milovidov)). [#27777](https://github.com/ClickHouse/ClickHouse/pull/27777) ([Sergei Semin](https://github.com/syominsergey))
|
||||
* Add CMake options to build with or without specific CPU instruction set. This is for [#17469](https://github.com/ClickHouse/ClickHouse/issues/17469) and [#27509](https://github.com/ClickHouse/ClickHouse/issues/27509). [#27508](https://github.com/ClickHouse/ClickHouse/pull/27508) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Fix linking of auxiliar programs when using dynamic libraries. [#26958](https://github.com/ClickHouse/ClickHouse/pull/26958) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Update RocksDB to `2021-07-16` master. [#26411](https://github.com/ClickHouse/ClickHouse/pull/26411) ([alexey-milovidov](https://github.com/alexey-milovidov)).

# CREATE FUNCTION {#create-function}
|
||||
|
||||
Creates a user defined function from a lambda expression. The expression must consist of function parameters, constants, operators, or other function calls.
|
||||
|
||||
**Syntax**
|
||||
|
||||
```sql
|
||||
CREATE FUNCTION name AS (parameter0, ...) -> expression
|
||||
```
|
||||
A function can have an arbitrary number of parameters.
|
||||
|
||||
There are a few restrictions:
|
||||
|
||||
- The name of a function must be unique among user defined and system functions.
|
||||
- Recursive functions are not allowed.
|
||||
- All variables used by a function must be specified in its parameter list.
|
||||
|
||||
If any restriction is violated then an exception is raised.
|
||||
|
||||
**Example**
|
||||

# CREATE FUNCTION {#create-function}
|
||||
|
||||
Создает пользовательскую функцию из лямбда-выражения. Выражение должно состоять из параметров функции, констант, операторов и вызовов других функций.
|
||||
|
||||
**Синтаксис**
|
||||
|
||||
```sql
|
||||
CREATE FUNCTION name AS (parameter0, ...) -> expression
|
||||
```
|
||||
У функции может быть произвольное число параметров.
|
||||
|
||||
Существует несколько ограничений на создаваемые функции:
|
||||
|
||||
- Имя функции должно быть уникальным среди всех пользовательских и системных функций.
|
||||
- Рекурсивные функции запрещены.
|
||||
- Все переменные, используемые функцией, должны быть перечислены в списке ее параметров.
|
||||
|
||||
Если какое-нибудь ограничение нарушается, то при попытке создать функцию возникает исключение.
|
||||
|
||||
**Пример**
