# 2022 Changelog
|
||
|
||
### ClickHouse release v21.1.1.5646-prestable FIXME as compared to v20.12.1.5236-prestable
|
||
|
||
#### Backward Incompatible Change
|
||
* Prohibit toUnixTimestamp(Date()) (before it just returns UInt16 representation of Date). [#17376](https://github.com/ClickHouse/ClickHouse/pull/17376) ([Azat Khuzhin](https://github.com/azat)).
|
||
* Removed aggregate functions `timeSeriesGroupSum`, `timeSeriesGroupRateSum` because a friend of mine said they never worked. This fixes [#16869](https://github.com/ClickHouse/ClickHouse/issues/16869). If you have luck using these functions, write a email to clickhouse-feedback@yandex-team.com. [#17423](https://github.com/ClickHouse/ClickHouse/pull/17423) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||
* The setting `input_format_null_as_default` is enabled by default. [#17525](https://github.com/ClickHouse/ClickHouse/pull/17525) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||
* Set `insert_quorum_parallel` to 1 by default. It is significantly more convenient to use than "sequential" quorum inserts. But if you rely to sequential consistency, you should set the setting back to zero. [#17567](https://github.com/ClickHouse/ClickHouse/pull/17567) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||
* Restrict `ALTER MODIFY SETTING` from changing storage settings that affects data parts (`write_final_mark` and `enable_mixed_granularity_parts`). [#18306](https://github.com/ClickHouse/ClickHouse/pull/18306) ([Amos Bird](https://github.com/amosbird)).
|
||
* Check settings constraints for profile settings from config. Server will fail to start if users.xml contain settings that do not meet corresponding constraints. [#18486](https://github.com/ClickHouse/ClickHouse/pull/18486) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||
* Remove `sumburConsistentHash` function. This closes [#18120](https://github.com/ClickHouse/ClickHouse/issues/18120). [#18656](https://github.com/ClickHouse/ClickHouse/pull/18656) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||
* Add `DIV` and `MOD` operators. `DIV` implements integer division. This is needed for MySQL compatibility and for `sqllogictest`. This closes [#18707](https://github.com/ClickHouse/ClickHouse/issues/18707). It may introduce incompatibilities if you are using DIV or MOD as column names or aliases. In case of incompatibility, write aliases after AS keyword or wrap identifiers in quotes (either double quotes or backquotes). [#18760](https://github.com/ClickHouse/ClickHouse/pull/18760) ([Du Chuan](https://github.com/spongedu)).
|
||
|
||
#### New Feature
|
||
* Use https://github.com/lemire/fast_float to parse floating point numbers. [#16787](https://github.com/ClickHouse/ClickHouse/pull/16787) ([Maksim Kita](https://github.com/kitaisreal)).
|
||
* ... [#16819](https://github.com/ClickHouse/ClickHouse/pull/16819) ([pronvis](https://github.com/pronvis)).
|
||
* Provide a new aggregator combinator : `-SimpleState` to build SimpleAggregateFunction types via query. It's useful for defining MaterializedView of AggregatingMergeTree engine, and will benefit projections too. [#16853](https://github.com/ClickHouse/ClickHouse/pull/16853) ([Amos Bird](https://github.com/amosbird)).
|
||
* Added `mannWitneyUTest`, `studentTTest` and `welchTTest` aggregate functions. Refactored RankCorr a bit. [#16883](https://github.com/ClickHouse/ClickHouse/pull/16883) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||
* Add a setting optimize_on_insert. When enabled, do the same transformation for INSERTed block of data as if merge was done on this block (e.g. Replacing, Collapsing, Aggregating...). This setting will be enabled as default. This can influence Materialized View and MaterializeMySQL behaviour (see detailed description). This closes [#10683](https://github.com/ClickHouse/ClickHouse/issues/10683). [#16954](https://github.com/ClickHouse/ClickHouse/pull/16954) ([Kruglov Pavel](https://github.com/Avogar)).
|
||
* add ```*.zst``` compression/decompression support.It enables using ```*.zst``` in ```file()``` function and ```Content-encoding: zstd``` in http client.This closes [#16791 ](https://github.com/ClickHouse/ClickHouse/issues/16791). [#17144](https://github.com/ClickHouse/ClickHouse/pull/17144) ([Abi Palagashvili](https://github.com/fibersel)).
|
||
* * IP Dictionary supports `IPv4` / `IPv6` types directly. [#17571](https://github.com/ClickHouse/ClickHouse/pull/17571) ([Vladimir C](https://github.com/vdimir)).
|
||
* related: [#16176](https://github.com/ClickHouse/ClickHouse/issues/16176) Usage: ``` set limit = 10; set offset = 20; ``` this two settings will affect SELECT query as if it is added like ``` select * from ($your_original_select_query) tmp limit xxx offset xxx; ```. [#17633](https://github.com/ClickHouse/ClickHouse/pull/17633) ([hexiaoting](https://github.com/hexiaoting)).
|
||
* Add asynchronous metrics on total amount of rows, bytes and parts in MergeTree tables. This fix [#11714](https://github.com/ClickHouse/ClickHouse/issues/11714). [#17639](https://github.com/ClickHouse/ClickHouse/pull/17639) ([flynn](https://github.com/ucasfl)).
|
||
* Introduce `DETACH TABLE/VIEW ... PERMANENTLY` syntax, so that after restarting the table does not reappear back automatically (only by explicit request). The table can still be attached back using the short syntax ATTACH TABLE. Implements [#5555](https://github.com/ClickHouse/ClickHouse/issues/5555). Fixes [#13850](https://github.com/ClickHouse/ClickHouse/issues/13850). [#17642](https://github.com/ClickHouse/ClickHouse/pull/17642) ([filimonov](https://github.com/filimonov)).
|
||
* Adds a new table called `system.distributed_ddl_queue` that displays the queries in the DDL worker queue. [#17656](https://github.com/ClickHouse/ClickHouse/pull/17656) ([Bharat Nallan](https://github.com/bharatnc)).
|
||
* Add function `encodeXMLComponent` to escape characters to place string into XML text node or attribute. [#17659](https://github.com/ClickHouse/ClickHouse/pull/17659) ([nauta](https://github.com/nautaa)).
|
||
* Now clickhouse-client supports opening EDITOR to edit commands. `Alt-Shift-E`. [#17665](https://github.com/ClickHouse/ClickHouse/pull/17665) ([Amos Bird](https://github.com/amosbird)).
|
||
* Add support for PROXYv1 protocol to wrap native TCP interface. Allow quotas to be keyed by proxy-forwarded IP address (applied for PROXYv1 address and for X-Forwarded-For from HTTP interface). This is useful when you provide access to ClickHouse only via trusted proxy (e.g. CloudFlare) but want to account user resources by their original IP addresses. This fixes [#17268](https://github.com/ClickHouse/ClickHouse/issues/17268). [#17707](https://github.com/ClickHouse/ClickHouse/pull/17707) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||
* Add ability to use custom TLD list in functions `firstSignificantSubdomainCustom`, `cutToFirstSignificantSubdomainCustom`. [#17748](https://github.com/ClickHouse/ClickHouse/pull/17748) ([Azat Khuzhin](https://github.com/azat)).
|
||
* Clickhouse-benchmark added query parameter. [#17832](https://github.com/ClickHouse/ClickHouse/pull/17832) ([Maksim Kita](https://github.com/kitaisreal)).
|
||
* Extended `OPTIMIZE ... DEDUPLICATE` syntax to allow explicit (or implicit with asterisk/column transformers) list of columns to check for duplicates on. ... [#17846](https://github.com/ClickHouse/ClickHouse/pull/17846) ([Vasily Nemkov](https://github.com/Enmk)).
|
||
* Add settings `min_compress_block_size` and `max_compress_block_size` to MergeTreeSettings, which have higher priority than the global settings and take effect when they are set. close [13890](https://github.com/ClickHouse/ClickHouse/issues/13890). [#17867](https://github.com/ClickHouse/ClickHouse/pull/17867) ([flynn](https://github.com/ucasfl)).
|
||
* Implemented `ATTACH TABLE name FROM 'path/to/data/' (col1 Type1, ...` query. It creates new table with provided structure and attaches table data from provided directory in `user_files`. [#17903](https://github.com/ClickHouse/ClickHouse/pull/17903) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||
* Added `arrayMin`, `arrayMax`, `arrayAvg` aggregation functions. [#18032](https://github.com/ClickHouse/ClickHouse/pull/18032) ([Maksim Kita](https://github.com/kitaisreal)).
|
||
* Support `SHOW SETTINGS` statement to show parameters in system.settings. `SHOW CHANGED SETTINGS` and `LIKE/ILIKE` clause are also supported. [#18056](https://github.com/ClickHouse/ClickHouse/pull/18056) ([Jianmei Zhang](https://github.com/zhangjmruc)).
|
||
* Allow create table as select with columns specification. Example `CREATE TABLE t1 (x String) ENGINE = Memory AS SELECT 1;`. [#18060](https://github.com/ClickHouse/ClickHouse/pull/18060) ([Maksim Kita](https://github.com/kitaisreal)).
|
||
* - IP Dictionary supports key fetching. Resolves [#18241](https://github.com/ClickHouse/ClickHouse/issues/18241). [#18480](https://github.com/ClickHouse/ClickHouse/pull/18480) ([Vladimir C](https://github.com/vdimir)).
|
||
* Implemented `REPLACE TABLE` and `CREATE OR REPLACE TABLE` queries. [#18521](https://github.com/ClickHouse/ClickHouse/pull/18521) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||
* Added function `byteSize` to estimate of uncompressed byte size of its arguments in memory. E.g. for UInt32 argument it will return constant 4, for String argument - the string length + 9. The function can take multiple arguments. The typical application is byteSize(*). [#18579](https://github.com/ClickHouse/ClickHouse/pull/18579) ([Ping Yu](https://github.com/pingyu)).
|
||
* Add `query_id` column to `system.part_log` for inserted parts. closes [#10097](https://github.com/ClickHouse/ClickHouse/issues/10097). [#18644](https://github.com/ClickHouse/ClickHouse/pull/18644) ([flynn](https://github.com/ucasfl)).
|
||
* Now we have a new storage setting `max_partitions_to_read` for tables in the MergeTree family. It limits the max number of partitions that can be accessed in one query. A user setting `force_max_partition_limit` is also added to enforce this constraint. [#18712](https://github.com/ClickHouse/ClickHouse/pull/18712) ([Amos Bird](https://github.com/amosbird)).
|
||
* Function `position` now supports `position(needle in haystack)` synax for SQL compatibility. This closes [#18701](https://github.com/ClickHouse/ClickHouse/issues/18701). ... [#18779](https://github.com/ClickHouse/ClickHouse/pull/18779) ([Jianmei Zhang](https://github.com/zhangjmruc)).

|
||
* Now the `-If` combinator is devirtualized, and `count` is properly vectorized. This is for https://github.com/ClickHouse/ClickHouse/pull/17041. [#17043](https://github.com/ClickHouse/ClickHouse/pull/17043) ([Amos Bird](https://github.com/amosbird)).
|
||

|
||
* Add `--no-system-table` option for `clickhouse-local` to run without system tables. This avoids initialization of `DateLUT` that may take noticeable amount of time (tens of milliseconds) at startup. [#18899](https://github.com/ClickHouse/ClickHouse/pull/18899) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||
|
||

|
||
* Now set indices will work with `GLOBAL IN`. This fixes [#17232](https://github.com/ClickHouse/ClickHouse/issues/17232) , [#5576](https://github.com/ClickHouse/ClickHouse/issues/5576) . [#17253](https://github.com/ClickHouse/ClickHouse/pull/17253) ([Amos Bird](https://github.com/amosbird)).
|
||
* Avoid possible stack overflow in bigint conversion. Big integers are experimental. [#17269](https://github.com/ClickHouse/ClickHouse/pull/17269) ([flynn](https://github.com/ucasfl)).
|

|
||
* Now queries coming to the server via MySQL and PostgreSQL protocols have distinctive interface types (which can be seen in the `interface` column of the table`system.query_log`): `4` for MySQL, and `5` for PostgreSQL, instead of formerly used `1` which is now used for the native protocol only. [#17437](https://github.com/ClickHouse/ClickHouse/pull/17437) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||
* Allow specifying [TTL](https://clickhouse.tech/docs/en/engines/table-engines/mergetree-family/mergetree/#mergetree-table-ttl) to remove old entries from [system log tables](https://clickhouse.tech/docs/en/operations/system-tables/), using the `<ttl>` attribute in `config.xml`.

|
||
* Export asynchronous metrics of all servers current threads. It's useful to track down issues like https://github.com/ClickHouse-Extras/poco/pull/28. [#17463](https://github.com/ClickHouse/ClickHouse/pull/17463) ([Amos Bird](https://github.com/amosbird)).
|
||
* Export current max ddl entry executed by DDLWorker. It's useful to check if DDLWorker hangs somewhere. [#17464](https://github.com/ClickHouse/ClickHouse/pull/17464) ([Amos Bird](https://github.com/amosbird)).
|
||
* Query obfuscator: avoid usage of some SQL keywords for identifier names. [#17526](https://github.com/ClickHouse/ClickHouse/pull/17526) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

|
||
* system.query_log now has extensive information to achieve better query analysis. [#17726](https://github.com/ClickHouse/ClickHouse/pull/17726) ([Amos Bird](https://github.com/amosbird)).
|
||
* Check system log tables' engine definition grammatically to prevent some configuration errors. Notes that this grammar check is not semantical, that means such mistakes as non-existent columns / expression functions would be not found out util the table is created. [#17739](https://github.com/ClickHouse/ClickHouse/pull/17739) ([Du Chuan](https://github.com/spongedu)).
|
||
* Improves the path concatenation of zookeeper paths inside DDLWorker. [#17767](https://github.com/ClickHouse/ClickHouse/pull/17767) ([Bharat Nallan](https://github.com/bharatnc)).

||
* - Let the possibility to override timeout value for running script using the ClickHouse docker image. [#17818](https://github.com/ClickHouse/ClickHouse/pull/17818) ([Guillaume Tassery](https://github.com/YiuRULE)).
|
||
* Add metrics(Parts, PartsActive, PartsInactive) for part number in MergeTree in clickhouse. [#17838](https://github.com/ClickHouse/ClickHouse/pull/17838) ([徐炘](https://github.com/weeds085490)).
|
||
* Add diagnostic information when two merge tables try to read each other's data. [#17854](https://github.com/ClickHouse/ClickHouse/pull/17854) ([徐炘](https://github.com/weeds085490)).
|
||
* Hints for column names. [#17112](https://github.com/ClickHouse/ClickHouse/issues/17112). [#17857](https://github.com/ClickHouse/ClickHouse/pull/17857) ([fastio](https://github.com/fastio)).
|
||
* Support for async tasks in `PipelineExecutor`. Initial support of async sockets for remote queries. [#17868](https://github.com/ClickHouse/ClickHouse/pull/17868) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||
* `allow_introspection_functions=0` prohibits usage of introspection functions but doesn't prohibit giving grants for them anymore (the grantee will need to set `allow_introspection_functions=1` for himself to be able to use that grant). Similarly `allow_ddl=0` prohibits usage of DDL commands but doesn't prohibit giving grants for them anymore. [#17908](https://github.com/ClickHouse/ClickHouse/pull/17908) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||
* Ability to set custom metadata when putting S3 object. [#17909](https://github.com/ClickHouse/ClickHouse/pull/17909) ([Pavel Kovalenko](https://github.com/Jokser)).
|
||
* Adaptive choose of single/multi part upload in WriteBufferFromS3. Single part upload is controlled by a new setting 'max_single_part_upload_size'. [#17934](https://github.com/ClickHouse/ClickHouse/pull/17934) ([Pavel Kovalenko](https://github.com/Jokser)).
|
||
* Forcibly removing empty or bad metadata files from filesystem for DiskS3. S3 is an experimental feature. [#17935](https://github.com/ClickHouse/ClickHouse/pull/17935) ([Pavel Kovalenko](https://github.com/Jokser)).
|
||
* Now the table function `merge()` requires the current user to have the `SELECT` privilege on each table it receives data from. This PR fixes [#16964](https://github.com/ClickHouse/ClickHouse/issues/16964). [#17983](https://github.com/ClickHouse/ClickHouse/pull/17983) ([Vitaly Baranov](https://github.com/vitlibar)).
