### <a id="2212"></a> ClickHouse release 22.12, 2022-12-15
|
||||
|
||||
#### Upgrade Notes
|
||||
* Fixed backward incompatibility in (de)serialization of states of `min`, `max`, `any*`, `argMin`, `argMax` aggregate functions with `String` argument. The incompatibility affects 22.9, 22.10 and 22.11 branches (fixed since 22.9.6, 22.10.4 and 22.11.2 correspondingly). Some minor releases of 22.3, 22.7 and 22.8 branches are also affected: 22.3.13...22.3.14 (fixed since 22.3.15), 22.8.6...22.8.9 (fixed since 22.8.10), 22.7.6 and newer (will not be fixed in 22.7, we recommend upgrading from 22.7.* to 22.8.10 or newer). This release note does not concern users that have never used affected versions. Incompatible versions append an extra `'\0'` to strings when reading states of the aggregate functions mentioned above. For example, if an older version saved state of `anyState('foobar')` to `state_column` then the incompatible version will print `'foobar\0'` on `anyMerge(state_column)`. Also incompatible versions write states of the aggregate functions without trailing `'\0'`. Newer versions (that have the fix) can correctly read data written by all versions including incompatible versions, except one corner case. If an incompatible version saved a state with a string that actually ends with null character, then newer version will trim trailing `'\0'` when reading state of affected aggregate function. For example, if an incompatible version saved state of `anyState('abrac\0dabra\0')` to `state_column` then newer versions will print `'abrac\0dabra'` on `anyMerge(state_column)`. The issue also affects distributed queries when an incompatible version works in a cluster together with older or newer versions. [#43038](https://github.com/ClickHouse/ClickHouse/pull/43038) ([Alexander Tokmakov](https://github.com/tavplubix), [Raúl Marín](https://github.com/Algunenano)). Note: all the official ClickHouse builds already include the patches. This is not necessarily true for unofficial third-party builds that should be avoided.
|
||||
|
||||
#### New Feature
|
||||
* Add `BSONEachRow` input/output format. In this format, ClickHouse formats/parses each row as a separate BSON document and each column is formatted/parsed as a single BSON field with the column name as the key. [#42033](https://github.com/ClickHouse/ClickHouse/pull/42033) ([mark-polokhov](https://github.com/mark-polokhov)).
|
||||
* Add `grace_hash` JOIN algorithm, it can be enabled with `SET join_algorithm = 'grace_hash'`. [#38191](https://github.com/ClickHouse/ClickHouse/pull/38191) ([BigRedEye](https://github.com/BigRedEye), [Vladimir C](https://github.com/vdimir)).
|
||||
* Allow configuring password complexity rules and checks for creating and changing users. [#43719](https://github.com/ClickHouse/ClickHouse/pull/43719) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Mask sensitive information in logs; mask secret parts in the output of queries `SHOW CREATE TABLE` and `SELECT FROM system.tables`. Also resolves [#41418](https://github.com/ClickHouse/ClickHouse/issues/41418). [#43227](https://github.com/ClickHouse/ClickHouse/pull/43227) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Add `GROUP BY ALL` syntax: [#37631](https://github.com/ClickHouse/ClickHouse/issues/37631). [#42265](https://github.com/ClickHouse/ClickHouse/pull/42265) ([刘陶峰](https://github.com/taofengliu)).
|
||||
* Add `FROM table SELECT column` syntax. [#41095](https://github.com/ClickHouse/ClickHouse/pull/41095) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Added function `concatWithSeparator` and `concat_ws` as an alias for Spark SQL compatibility. A function `concatWithSeparatorAssumeInjective` added as a variant to enable GROUP BY optimization, similarly to `concatAssumeInjective`. [#43749](https://github.com/ClickHouse/ClickHouse/pull/43749) ([李扬](https://github.com/taiyang-li)).
|
||||
* Added `multiplyDecimal` and `divideDecimal` functions for decimal operations with fixed precision. [#42438](https://github.com/ClickHouse/ClickHouse/pull/42438) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* Added `system.moves` table with list of currently moving parts. [#42660](https://github.com/ClickHouse/ClickHouse/pull/42660) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Add support for embedded Prometheus endpoint for ClickHouse Keeper. [#43087](https://github.com/ClickHouse/ClickHouse/pull/43087) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Support numeric literals with `_` as the separator, for example, `1_000_000`. [#43925](https://github.com/ClickHouse/ClickHouse/pull/43925) ([jh0x](https://github.com/jh0x)).
|
||||
* Added possibility to use an array as a second parameter for `cutURLParameter` function. It will cut multiple parameters. Close [#6827](https://github.com/ClickHouse/ClickHouse/issues/6827). [#43788](https://github.com/ClickHouse/ClickHouse/pull/43788) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* Add a column with the expression of the index in the `system.data_skipping_indices` table. [#43308](https://github.com/ClickHouse/ClickHouse/pull/43308) ([Guillaume Tassery](https://github.com/YiuRULE)).
|
||||
* Add column `engine_full` to system table `databases` so that users can access the entire engine definition of a database via system tables. [#43468](https://github.com/ClickHouse/ClickHouse/pull/43468) ([凌涛](https://github.com/lingtaolf)).
|
||||
* New hash function [xxh3](https://github.com/Cyan4973/xxHash) added. Also, the performance of `xxHash32` and `xxHash64` are improved on ARM thanks to a library update. [#43411](https://github.com/ClickHouse/ClickHouse/pull/43411) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Added support to define constraints for merge tree settings. For example you can forbid overriding the `storage_policy` by users. [#43903](https://github.com/ClickHouse/ClickHouse/pull/43903) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Add a new setting `input_format_json_read_objects_as_strings` that allows the parsing of nested JSON objects into Strings in all JSON input formats. This setting is disabled by default. [#44052](https://github.com/ClickHouse/ClickHouse/pull/44052) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### Experimental Feature
|
||||
* Support deduplication for asynchronous inserts. Before this change, async inserts did not support deduplication, because multiple small inserts coexisted in one inserted batch. Closes [#38075](https://github.com/ClickHouse/ClickHouse/issues/38075). [#43304](https://github.com/ClickHouse/ClickHouse/pull/43304) ([Han Fei](https://github.com/hanfei1991)).
|
||||
* Add support for cosine distance for the experimental Annoy (vector similarity search) index. [#42778](https://github.com/ClickHouse/ClickHouse/pull/42778) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
* Add `CREATE / ALTER / DROP NAMED COLLECTION` queries. [#43252](https://github.com/ClickHouse/ClickHouse/pull/43252) ([Kseniia Sumarokova](https://github.com/kssenii)). This feature is under development and the queries are not effective as of version 22.12. This changelog entry is added only to avoid confusion. Restrict default access to named collections to the user defined in config. This requires that `show_named_collections = 1` is set to be able to see them. [#43325](https://github.com/ClickHouse/ClickHouse/pull/43325) ([Kseniia Sumarokova](https://github.com/kssenii)). The `system.named_collections` table is introduced [#43147](https://github.com/ClickHouse/ClickHouse/pull/43147) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Add settings `max_streams_for_merge_tree_reading` and `allow_asynchronous_read_from_io_pool_for_merge_tree`. Setting `max_streams_for_merge_tree_reading` limits the number of reading streams for MergeTree tables. Setting `allow_asynchronous_read_from_io_pool_for_merge_tree` enables a background I/O pool to read from `MergeTree` tables. This may increase performance for I/O bound queries if used together with `max_streams_to_max_threads_ratio` or `max_streams_for_merge_tree_reading`. [#43260](https://github.com/ClickHouse/ClickHouse/pull/43260) ([Nikolai Kochetov](https://github.com/KochetovNicolai)). This improves performance up to 100 times in case of high latency storage, low number of CPU and high number of data parts.
|
||||
* Settings `merge_tree_min_rows_for_concurrent_read_for_remote_filesystem/merge_tree_min_bytes_for_concurrent_read_for_remote_filesystem` did not respect adaptive granularity. Fat rows did not decrease the number of read rows (as it was done for `merge_tree_min_rows_for_concurrent_read/merge_tree_min_bytes_for_concurrent_read`, which could lead to high memory usage when using remote filesystems. [#43965](https://github.com/ClickHouse/ClickHouse/pull/43965) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Optimized the number of list requests to ZooKeeper or ClickHouse Keeper when selecting a part to merge. Previously it could produce thousands of requests in some cases. Fixes [#43647](https://github.com/ClickHouse/ClickHouse/issues/43647). [#43675](https://github.com/ClickHouse/ClickHouse/pull/43675) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
* Optimization is getting skipped now if `max_size_to_preallocate_for_aggregation` has too small a value. The default value of this setting increased to `10^8`. [#43945](https://github.com/ClickHouse/ClickHouse/pull/43945) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Speed-up server shutdown by avoiding cleaning up of old data parts. Because it is unnecessary after https://github.com/ClickHouse/ClickHouse/pull/41145. [#43760](https://github.com/ClickHouse/ClickHouse/pull/43760) ([Sema Checherinda](https://github.com/CheSema)).
|
||||
* Merging on initiator now uses the same memory bound approach as merging of local aggregation results if `enable_memory_bound_merging_of_aggregation_results` is set. [#40879](https://github.com/ClickHouse/ClickHouse/pull/40879) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Keeper improvement: try syncing logs to disk in parallel with replication. [#43450](https://github.com/ClickHouse/ClickHouse/pull/43450) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Keeper improvement: requests are batched more often. The batching can be controlled with the new setting `max_requests_quick_batch_size`. [#43686](https://github.com/ClickHouse/ClickHouse/pull/43686) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
|
||||
#### Improvement
|
||||
* Implement referential dependencies and use them to create tables in the correct order while restoring from a backup. [#43834](https://github.com/ClickHouse/ClickHouse/pull/43834) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Substitute UDFs in `CREATE` query to avoid failures during loading at startup. Additionally, UDFs can now be used as `DEFAULT` expressions for columns. [#43539](https://github.com/ClickHouse/ClickHouse/pull/43539) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Change how the following queries delete parts: TRUNCATE TABLE, ALTER TABLE DROP PART, ALTER TABLE DROP PARTITION. Now, these queries make empty parts which cover the old parts. This makes the TRUNCATE query work without a followedexclusive lock which means concurrent reads aren't locked. Also achieved durability in all those queries. If the request succeeds, then no resurrected parts appear later. Note that atomicity is achieved only with transaction scope. [#41145](https://github.com/ClickHouse/ClickHouse/pull/41145) ([Sema Checherinda](https://github.com/CheSema)).
|
||||
* `SET param_x` query no longer requires manual string serialization for the value of the parameter. For example, query `SET param_a = '[\'a\', \'b\']'` can now be written like `SET param_a = ['a', 'b']`. [#41874](https://github.com/ClickHouse/ClickHouse/pull/41874) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Show read rows in the progress indication while reading from STDIN from client. Closes [#43423](https://github.com/ClickHouse/ClickHouse/issues/43423). [#43442](https://github.com/ClickHouse/ClickHouse/pull/43442) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Show progress bar while reading from s3 table function / engine. [#43454](https://github.com/ClickHouse/ClickHouse/pull/43454) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* `filesystemAvailable` and related functions support one optional argument with disk name, and change `filesystemFree` to `filesystemUnreserved`. Closes [#35076](https://github.com/ClickHouse/ClickHouse/issues/35076). [#42064](https://github.com/ClickHouse/ClickHouse/pull/42064) ([flynn](https://github.com/ucasfl)).
|
||||
* Integration with LDAP: increased the default value of search_limit to 256, and added LDAP server config option to change that to an arbitrary value. Closes: [#42276](https://github.com/ClickHouse/ClickHouse/issues/42276). [#42461](https://github.com/ClickHouse/ClickHouse/pull/42461) ([Vasily Nemkov](https://github.com/Enmk)).
|
||||
* Allow the removal of sensitive information (see the `query_masking_rules` in the configuration file) from the exception messages as well. Resolves [#41418](https://github.com/ClickHouse/ClickHouse/issues/41418). [#42940](https://github.com/ClickHouse/ClickHouse/pull/42940) ([filimonov](https://github.com/filimonov)).
|
||||
* Support queries like `SHOW FULL TABLES ...` for MySQL compatibility. [#43910](https://github.com/ClickHouse/ClickHouse/pull/43910) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
* Keeper improvement: Add 4lw command `rqld` which can manually assign a node as leader. [#43026](https://github.com/ClickHouse/ClickHouse/pull/43026) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* Apply connection timeout settings for Distributed async INSERT from the query. [#43156](https://github.com/ClickHouse/ClickHouse/pull/43156) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* The `unhex` function now supports `FixedString` arguments. [issue42369](https://github.com/ClickHouse/ClickHouse/issues/42369). [#43207](https://github.com/ClickHouse/ClickHouse/pull/43207) ([DR](https://github.com/freedomDR)).
|
||||
* Priority is given to deleting completely expired parts according to the TTL rules, see [#42869](https://github.com/ClickHouse/ClickHouse/issues/42869). [#43222](https://github.com/ClickHouse/ClickHouse/pull/43222) ([zhongyuankai](https://github.com/zhongyuankai)).
|
||||
* More precise and reactive CPU load indication in clickhouse-client. [#43307](https://github.com/ClickHouse/ClickHouse/pull/43307) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Support reading of subcolumns of nested types from storage `S3` and table function `s3` with formats `Parquet`, `Arrow` and `ORC`. [#43329](https://github.com/ClickHouse/ClickHouse/pull/43329) ([chen](https://github.com/xiedeyantu)).
|
||||
* Add `table_uuid` column to the `system.parts` table. [#43404](https://github.com/ClickHouse/ClickHouse/pull/43404) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added client option to display the number of locally processed rows in non-interactive mode (`--print-num-processed-rows`). [#43407](https://github.com/ClickHouse/ClickHouse/pull/43407) ([jh0x](https://github.com/jh0x)).
|
||||
* Implement `aggregation-in-order` optimization on top of a query plan. It is enabled by default (but works only together with `optimize_aggregation_in_order`, which is disabled by default). Set `query_plan_aggregation_in_order = 0` to use the previous AST-based version. [#43592](https://github.com/ClickHouse/ClickHouse/pull/43592) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Allow to collect profile events with `trace_type = 'ProfileEvent'` to `system.trace_log` on each increment with current stack, profile event name and value of the increment. It can be enabled by the setting `trace_profile_events` and used to investigate performance of queries. [#43639](https://github.com/ClickHouse/ClickHouse/pull/43639) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Add a new setting `input_format_max_binary_string_size` to limit string size in RowBinary format. [#43842](https://github.com/ClickHouse/ClickHouse/pull/43842) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* When ClickHouse requests a remote HTTP server, and it returns an error, the numeric HTTP code was not displayed correctly in the exception message. Closes [#43919](https://github.com/ClickHouse/ClickHouse/issues/43919). [#43920](https://github.com/ClickHouse/ClickHouse/pull/43920) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Correctly report errors in queries even when multiple JOINs optimization is taking place. [#43583](https://github.com/ClickHouse/ClickHouse/pull/43583) ([Salvatore](https://github.com/tbsal)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|
||||
|
||||
* Systemd integration now correctly notifies systemd that the service is really started and is ready to serve requests. [#43400](https://github.com/ClickHouse/ClickHouse/pull/43400) ([Коренберг Марк](https://github.com/socketpair)).
|
||||
* Added the option to build ClickHouse with OpenSSL using the [OpenSSL FIPS Module](https://www.openssl.org/docs/man3.0/man7/fips_module.html). This build type has not been tested to validate security and is not supported. [#43991](https://github.com/ClickHouse/ClickHouse/pull/43991) ([Boris Kuschel](https://github.com/bkuschel)).
|
||||
* Upgrade to the new `DeflateQpl` compression codec which has been implemented in a previous PR (details: https://github.com/ClickHouse/ClickHouse/pull/39494). This patch improves codec on below aspects: 1. QPL v0.2.0 to QPL v0.3.0 [Intel® Query Processing Library (QPL)](https://github.com/intel/qpl) 2. Improve CMake file for fixing QPL build issues for QPL v0.3.0. 3. Link the QPL library with libaccel-config at build time instead of runtime loading on QPL v0.2.0 (dlopen) 4. Fixed log print issue in CompressionCodecDeflateQpl.cpp. [#44024](https://github.com/ClickHouse/ClickHouse/pull/44024) ([jasperzhu](https://github.com/jinjunzh)).
|
||||
|
||||
#### Bug Fix (user-visible misbehavior in official stable or prestable release)
|
||||
|
||||
* Fixed bug which could lead to deadlock while using asynchronous inserts. [#43233](https://github.com/ClickHouse/ClickHouse/pull/43233) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Fix some incorrect logic in AST level optimization `optimize_normalize_count_variants`. [#43873](https://github.com/ClickHouse/ClickHouse/pull/43873) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Fix a case when mutations are not making progress when checksums do not match between replicas (e.g. caused by a change in data format on an upgrade). [#36877](https://github.com/ClickHouse/ClickHouse/pull/36877) ([nvartolomei](https://github.com/nvartolomei)).
|
||||
* Fix the `skip_unavailable_shards` optimization which did not work with the `hdfsCluster` table function. [#43236](https://github.com/ClickHouse/ClickHouse/pull/43236) ([chen](https://github.com/xiedeyantu)).
|
||||
* Fix `s3` support for the `?` wildcard. Closes [#42731](https://github.com/ClickHouse/ClickHouse/issues/42731). [#43253](https://github.com/ClickHouse/ClickHouse/pull/43253) ([chen](https://github.com/xiedeyantu)).
|
||||
* Fix functions `arrayFirstOrNull` and `arrayLastOrNull` or null when the array contains `Nullable` elements. [#43274](https://github.com/ClickHouse/ClickHouse/pull/43274) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Fix incorrect `UserTimeMicroseconds`/`SystemTimeMicroseconds` accounting related to Kafka tables. [#42791](https://github.com/ClickHouse/ClickHouse/pull/42791) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Do not suppress exceptions in `web` disks. Fix retries for the `web` disk. [#42800](https://github.com/ClickHouse/ClickHouse/pull/42800) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fixed (logical) race condition between inserts and dropping materialized views. A race condition happened when a Materialized View was dropped at the same time as an INSERT, where the MVs were present as a dependency of the insert at the begining of the execution, but the table has been dropped by the time the insert chain tries to access it, producing either an `UNKNOWN_TABLE` or `TABLE_IS_DROPPED` exception, and stopping the insertion. After this change, we avoid these exceptions and just continue with the insert if the dependency is gone. [#43161](https://github.com/ClickHouse/ClickHouse/pull/43161) ([AlfVII](https://github.com/AlfVII)).
|
||||
* Fix undefined behavior in the `quantiles` function, which might lead to uninitialized memory. Found by fuzzer. This closes [#44066](https://github.com/ClickHouse/ClickHouse/issues/44066). [#44067](https://github.com/ClickHouse/ClickHouse/pull/44067) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Additional check on zero uncompressed size is added to `CompressionCodecDelta`. [#43255](https://github.com/ClickHouse/ClickHouse/pull/43255) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Flatten arrays from Parquet to avoid an issue with inconsistent data in arrays. These incorrect files can be generated by Apache Iceberg. [#43297](https://github.com/ClickHouse/ClickHouse/pull/43297) ([Arthur Passos](https://github.com/arthurpassos)).
|
||||
* Fix bad cast from `LowCardinality` column when using short circuit function execution. [#43311](https://github.com/ClickHouse/ClickHouse/pull/43311) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Fixed queries with `SAMPLE BY` with prewhere optimization on tables using `Merge` engine. [#43315](https://github.com/ClickHouse/ClickHouse/pull/43315) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Check and compare the content of the `format_version` file in `MergeTreeData` so that tables can be loaded even if the storage policy was changed. [#43328](https://github.com/ClickHouse/ClickHouse/pull/43328) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Fix possible (very unlikely) "No column to rollback" logical error during INSERT into `Buffer` tables. [#43336](https://github.com/ClickHouse/ClickHouse/pull/43336) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fix a bug that allowed the parser to parse an unlimited amount of round brackets into one function if `allow_function_parameters` is set. [#43350](https://github.com/ClickHouse/ClickHouse/pull/43350) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* `MaterializeMySQL` (experimental feature) support DDL： `drop table t1, t2` and compatible with most of MySQL DROP DDL. [#43366](https://github.com/ClickHouse/ClickHouse/pull/43366) ([zzsmdfj](https://github.com/zzsmdfj)).
|
||||
* `session_log` (experimental feature): Fixed the inability to log in (because of failure to create the session_log entry) in a very rare case of messed up setting profiles. [#42641](https://github.com/ClickHouse/ClickHouse/pull/42641) ([Vasily Nemkov](https://github.com/Enmk)).

#### Backward Incompatible Change
|

@ -534,30 +650,30 @@
|
||||
* Add counters (ProfileEvents) for cases when query complexity limitation has been set and has reached (a separate counter for `overflow_mode` = `break` and `throw`). For example, if you have set up `max_rows_to_read` with `read_overflow_mode = 'break'`, looking at the value of `OverflowBreak` counter will allow distinguishing incomplete results. [#40205](https://github.com/ClickHouse/ClickHouse/pull/40205) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Fix memory accounting in case of "Memory limit exceeded" errors (previously [peak] memory usage was takes failed allocations into account). [#40249](https://github.com/ClickHouse/ClickHouse/pull/40249) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Add metrics for filesystem cache: `FilesystemCacheSize` and `FilesystemCacheElements`. [#40260](https://github.com/ClickHouse/ClickHouse/pull/40260) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Support hadoop secure RPC transfer (hadoop.rpc.protection=privacy and hadoop.rpc.protection=integrity). [#39411](https://github.com/ClickHouse/ClickHouse/pull/39411) ([michael1589](https://github.com/michael1589)).

|
||||
* Avoid continuously growing memory consumption of pattern cache when using functions multi(Fuzzy)Match(Any|AllIndices|AnyIndex)(). [#40264](https://github.com/ClickHouse/ClickHouse/pull/40264) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Add cache for schema inference for file/s3/hdfs/url table functions. Now, schema inference will be performed only on the first query to the file, all subsequent queries to the same file will use the schema from cache if data wasn't changed. Add system table system.schema_inference_cache with all current schemas in cache and system queries SYSTEM DROP SCHEMA CACHE [FOR FILE/S3/HDFS/URL] to drop schemas from cache. [#38286](https://github.com/ClickHouse/ClickHouse/pull/38286) ([Kruglov Pavel](https://github.com/Avogar)).

#### Build/Testing/Packaging Improvement
|
||||
|
||||
* [ClickFiddle](https://fiddle.clickhouse.com/): A new tool for testing ClickHouse versions in read/write mode (**Igor Baliuk**).
|
||||
* ClickHouse binary is made self-extracting [#35775](https://github.com/ClickHouse/ClickHouse/pull/35775) ([Yakov Olkhovskiy, Arthur Filatenkov](https://github.com/yakov-olkhovskiy)).
|
||||
* Update tzdata to 2022b to support the new timezone changes. See https://github.com/google/cctz/pull/226. Chile's 2022 DST start is delayed from September 4 to September 11. Iran plans to stop observing DST permanently, after it falls back on 2022-09-21. There are corrections of the historical time zone of Asia/Tehran in the year 1977: Iran adopted standard time in 1935, not 1946. In 1977 it observed DST from 03-21 23:00 to 10-20 24:00; its 1978 transitions were on 03-24 and 08-05, not 03-20 and 10-20; and its spring 1979 transition was on 05-27, not 03-21 (https://data.iana.org/time-zones/tzdb/NEWS). ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Former packages used to install systemd.service file to `/etc`. The files there are marked as `conf` and are not cleaned out, and not updated automatically. This PR cleans them out. [#39323](https://github.com/ClickHouse/ClickHouse/pull/39323) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).

* Ensure LSan is effective. [#39430](https://github.com/ClickHouse/ClickHouse/pull/39430) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* TSAN has issues with clang-14 (https://github.com/google/sanitizers/issues/1552, https://github.com/google/sanitizers/issues/1540), so here we build the TSAN binaries with clang-15. [#39450](https://github.com/ClickHouse/ClickHouse/pull/39450) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
|
||||
* Remove the option to build ClickHouse tools as separate executable programs. This fixes [#37847](https://github.com/ClickHouse/ClickHouse/issues/37847). [#39520](https://github.com/ClickHouse/ClickHouse/pull/39520) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

|
||||

|
||||
* Simplified function registration macro interface (`FUNCTION_REGISTER*`) to eliminate the step to add and call an extern function in the registerFunctions.cpp, it also makes incremental builds of a new function faster. [#38615](https://github.com/ClickHouse/ClickHouse/pull/38615) ([Li Yin](https://github.com/liyinsg)).

# 2022 Changelog
|
||||
|
||||
### ClickHouse release v22.12.1.1752-stable (688e488e930) FIXME as compared to v22.11.1.1360-stable (0d211ed1984)
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Fixed backward incompatibility in (de)serialization of states of `min`, `max`, `any*`, `argMin`, `argMax` aggregate functions with `String` argument. The incompatibility was introduced in https://github.com/ClickHouse/ClickHouse/pull/41431 and affects 22.9, 22.10 and 22.11 branches (fixed since 22.9.6, 22.10.4 and 22.11.2 correspondingly). Some minor releases of 22.3, 22.7 and 22.8 branches are also affected: 22.3.13...22.3.14 (fixed since 22.3.15), 22.8.6...22.8.9 (fixed since 22.8.10), 22.7.6 and newer (will not be fixed in 22.7, we recommend to upgrade from 22.7.* to 22.8.10 or newer). This release note does not concern users that have never used affected versions. Incompatible versions append extra `'\0'` to strings when reading states of the aggregate functions mentioned above. For example, if an older version saved state of `anyState('foobar')` to `state_column` then incompatible version will print `'foobar\0'` on `anyMerge(state_column)`. Also incompatible versions write states of the aggregate functions without trailing `'\0'`. Newer versions (that have the fix) can correctly read data written by all versions including incompatible versions, except one corner case. If an incompatible version saved a state with a string that actually ends with null character, then newer version will trim trailing `'\0'` when reading state of affected aggregate function. For example, if an incompatible version saved state of `anyState('abrac\0dabra\0')` to `state_column` then newer versions will print `'abrac\0dabra'` on `anyMerge(state_column)`. The issue also affects distributed queries when an incompatible version works in a cluster together with older or newer versions. [#43038](https://github.com/ClickHouse/ClickHouse/pull/43038) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
|
||||
#### New Feature
|
||||
* Add "grace_hash" join_algorithm. [#38191](https://github.com/ClickHouse/ClickHouse/pull/38191) ([BigRedEye](https://github.com/BigRedEye)).
|
||||
* Merging on initiator now uses the same memory bound approach as merging of local aggregation results if `enable_memory_bound_merging_of_aggregation_results` is set. [#40879](https://github.com/ClickHouse/ClickHouse/pull/40879) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Add BSONEachRow input/output format. In this format, ClickHouse formats/parses each row as a separated BSON Document and each column is formatted/parsed as a single BSON field with column name as a key. [#42033](https://github.com/ClickHouse/ClickHouse/pull/42033) ([mark-polokhov](https://github.com/mark-polokhov)).
|
||||
* close: [#37631](https://github.com/ClickHouse/ClickHouse/issues/37631). [#42265](https://github.com/ClickHouse/ClickHouse/pull/42265) ([刘陶峰](https://github.com/taofengliu)).
|
||||
* Added `multiplyDecimal` and `divideDecimal` functions for decimal operations with fixed precision. [#42438](https://github.com/ClickHouse/ClickHouse/pull/42438) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* Added `system.moves` table with list of currently moving parts. [#42660](https://github.com/ClickHouse/ClickHouse/pull/42660) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Keeper feature: add support for embedded Prometheus endpoint. [#43087](https://github.com/ClickHouse/ClickHouse/pull/43087) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Added age function to calculate difference between two dates or dates with time values expressed as number of full units. Close [#41115](https://github.com/ClickHouse/ClickHouse/issues/41115). [#43123](https://github.com/ClickHouse/ClickHouse/pull/43123) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* Add settings `max_streams_for_merge_tree_reading` and `allow_asynchronous_read_from_io_pool_for_merge_tree`. Setting `max_streams_for_merge_tree_reading` limits the number of reading streams for MergeTree tables. Setting `allow_asynchronous_read_from_io_pool_for_merge_tree` enables background I/O pool to read from `MergeTree` tables. This may increase performance for I/O bound queries if used together with `max_streams_to_max_threads_ratio` or `max_streams_for_merge_tree_reading`. [#43260](https://github.com/ClickHouse/ClickHouse/pull/43260) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Add the expression of the index on `data_skipping_indices` system table. [#43308](https://github.com/ClickHouse/ClickHouse/pull/43308) ([Guillaume Tassery](https://github.com/YiuRULE)).
|
||||
* New hash function [xxh3](https://github.com/Cyan4973/xxHash) added. Also performance of `xxHash32` and `xxHash64` improved on arm thanks to library update. [#43411](https://github.com/ClickHouse/ClickHouse/pull/43411) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* - Temporary data (for external sorting, aggregation, and JOINs) can share storage with the filesystem cache for remote disks and evict it, close [#42158](https://github.com/ClickHouse/ClickHouse/issues/42158). [#43457](https://github.com/ClickHouse/ClickHouse/pull/43457) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Add column `engine_full` to system table `databases` so that users can access whole engine definition of database via system tables. [#43468](https://github.com/ClickHouse/ClickHouse/pull/43468) ([凌涛](https://github.com/lingtaolf)).
|
||||
* Add password complexity rules and checks for creating a new user. [#43719](https://github.com/ClickHouse/ClickHouse/pull/43719) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Add function concatWithSeparator , like concat_ws in spark. [#43749](https://github.com/ClickHouse/ClickHouse/pull/43749) ([李扬](https://github.com/taiyang-li)).
|
||||
* Added constraints for merge tree settings. [#43903](https://github.com/ClickHouse/ClickHouse/pull/43903) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Support numeric literals with _ as separator. [#43925](https://github.com/ClickHouse/ClickHouse/pull/43925) ([jh0x](https://github.com/jh0x)).
|
||||
* Add a new setting `input_format_json_read_objects_as_strings` that allows to parse nested JSON objects into Strings in all JSON input formats. This setting is disable by default. [#44052](https://github.com/ClickHouse/ClickHouse/pull/44052) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Optimisation is getting skipped now if `max_size_to_preallocate_for_aggregation` has too small value. Default value of this setting increased to `10^8`. [#43945](https://github.com/ClickHouse/ClickHouse/pull/43945) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
|
||||
#### Improvement
|
||||
* Support numeric literals with underscores. closes [#28967](https://github.com/ClickHouse/ClickHouse/issues/28967). [#39129](https://github.com/ClickHouse/ClickHouse/pull/39129) ([unbyte](https://github.com/unbyte)).
|
||||
* Add `FROM table SELECT column` syntax. [#41095](https://github.com/ClickHouse/ClickHouse/pull/41095) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* This PR changes how followed queries delete parts: truncate table, alter table drop part, alter table drop partition. Now these queries make empty parts which cover old parts. This makes truncate query works without exclusive lock which means concurrent reads aren't locked. Also achieved durability in all those queries. If request is succeeded then no resurrected pars appear later. Note that atomicity is achieved only with transaction scope. [#41145](https://github.com/ClickHouse/ClickHouse/pull/41145) ([Sema Checherinda](https://github.com/CheSema)).
|
||||
* `SET param_x` query no longer requires manual string serialization for the value of the parameter. For example, query `SET param_a = '[\'a\', \'b\']'` can now be written like `SET param_a = ['a', 'b']`. [#41874](https://github.com/ClickHouse/ClickHouse/pull/41874) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* `filesystemAvailable` and related functions support one optional argument with disk name, and change `filesystemFree` to `filesystemUnreserved`. Closes [#35076](https://github.com/ClickHouse/ClickHouse/issues/35076). [#42064](https://github.com/ClickHouse/ClickHouse/pull/42064) ([flynn](https://github.com/ucasfl)).
|
||||
* Increased the default value of search_limit to 256, and added LDAP server config option to change that to an arbitrary value. Closes: [#42276](https://github.com/ClickHouse/ClickHouse/issues/42276). [#42461](https://github.com/ClickHouse/ClickHouse/pull/42461) ([Vasily Nemkov](https://github.com/Enmk)).
|
||||
* Add cosine distance for annoy. [#42778](https://github.com/ClickHouse/ClickHouse/pull/42778) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
* Allow to remove sensitive information from the exception messages also. Resolves [#41418](https://github.com/ClickHouse/ClickHouse/issues/41418). [#42940](https://github.com/ClickHouse/ClickHouse/pull/42940) ([filimonov](https://github.com/filimonov)).
|
||||
* Keeper improvement: Add 4lw command `rqld` which can manually assign a node as leader. [#43026](https://github.com/ClickHouse/ClickHouse/pull/43026) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* Apply connection timeouts settings for Distributed async INSERT from the query. [#43156](https://github.com/ClickHouse/ClickHouse/pull/43156) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* unhex function support FixedString arguments. [issue42369](https://github.com/ClickHouse/ClickHouse/issues/42369). [#43207](https://github.com/ClickHouse/ClickHouse/pull/43207) ([DR](https://github.com/freedomDR)).
|
||||
* Priority is given to deleting completely expired Parts，related [#42869](https://github.com/ClickHouse/ClickHouse/issues/42869). [#43222](https://github.com/ClickHouse/ClickHouse/pull/43222) ([zhongyuankai](https://github.com/zhongyuankai)).
|
||||
* Follow-up to https://github.com/ClickHouse/ClickHouse/pull/42484. Mask sensitive information in logs better; mask secret parts in the output of queries `SHOW CREATE TABLE` and `SELECT FROM system.tables`. Also resolves [#41418](https://github.com/ClickHouse/ClickHouse/issues/41418). [#43227](https://github.com/ClickHouse/ClickHouse/pull/43227) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Enable compress marks and primary key. [#43288](https://github.com/ClickHouse/ClickHouse/pull/43288) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
|
||||
* resolve issue [#38075](https://github.com/ClickHouse/ClickHouse/issues/38075) . Right now async insert doesn't support deduplication, because multiple small inserts will coexist in one part, which corespond multiple `block id`s. This solution is straitfoward: The change involves: 1. mark offsets for every inserts in every chunk 2. calculate multiple `block_id`s when sinker receive a chunk 3. get block number lock by these `block_id`s 3.1. if fails, remove the dup insert(s) and dup `block_id`(s) from block and recalculate `offsets` agian. 3.2. if succeeds, commit `block_id`'s and other items into keeper a. if fails, do 3.1 b. if succeeds, everything succeeds. [#43304](https://github.com/ClickHouse/ClickHouse/pull/43304) ([Han Fei](https://github.com/hanfei1991)).
|
||||
* More precise and reactive CPU load indication on client. [#43307](https://github.com/ClickHouse/ClickHouse/pull/43307) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Restrict default access to named collections for user defined in config. It must have explicit `show_named_collections=1` to be able to see them. [#43325](https://github.com/ClickHouse/ClickHouse/pull/43325) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Support reading of subcolumns of nested types from storage `S3` and table function `s3` with formats `Parquet`, `Arrow` and `ORC`. [#43329](https://github.com/ClickHouse/ClickHouse/pull/43329) ([chen](https://github.com/xiedeyantu)).
|
||||
* - Systemd integration now correctly notifies systemd that service is really started and is ready to server requests. [#43400](https://github.com/ClickHouse/ClickHouse/pull/43400) ([Коренберг Марк](https://github.com/socketpair)).
|
||||
* Add table_uuid to system.parts. [#43404](https://github.com/ClickHouse/ClickHouse/pull/43404) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added client option to display the number of locally processed rows in non-interactive mode (--print-num-processed-rows). [#43407](https://github.com/ClickHouse/ClickHouse/pull/43407) ([jh0x](https://github.com/jh0x)).
|
||||
* Show read rows while reading from stdin from client. Closes [#43423](https://github.com/ClickHouse/ClickHouse/issues/43423). [#43442](https://github.com/ClickHouse/ClickHouse/pull/43442) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Keeper improvement: try syncing logs to disk in parallel with replication. [#43450](https://github.com/ClickHouse/ClickHouse/pull/43450) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Show progress bar while reading from s3 table function / engine. [#43454](https://github.com/ClickHouse/ClickHouse/pull/43454) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Progress bar will show both read and written rows. [#43496](https://github.com/ClickHouse/ClickHouse/pull/43496) ([Ilya Yatsishin](https://github.com/qoega)).
|
||||
* Implement `aggregation-in-order` optimization on top of query plan. It is enabled by default (but works only together with `optimize_aggregation_in_order`, which is disabled by default). Set `query_plan_aggregation_in_order = 0` to use previous AST-based version. [#43592](https://github.com/ClickHouse/ClickHouse/pull/43592) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Allow to send profile events with `trace_type = 'ProfileEvent'` to `system.trace_log` on each increment with current stack, profile event name and value of increment. It can be enabled by setting `trace_profile_events` and used to debug performance of queries. [#43639](https://github.com/ClickHouse/ClickHouse/pull/43639) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Keeper improvement: requests are batched more often. The batching can be controlled with the new setting `max_requests_quick_batch_size`. [#43686](https://github.com/ClickHouse/ClickHouse/pull/43686) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Added possibility to use array as a second parameter for cutURLParameter function. Close [#6827](https://github.com/ClickHouse/ClickHouse/issues/6827). [#43788](https://github.com/ClickHouse/ClickHouse/pull/43788) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* Implement referential dependencies and use them to create tables in the correct order while restoring from a backup. [#43834](https://github.com/ClickHouse/ClickHouse/pull/43834) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Add a new setting `input_format_max_binary_string_size` to limit string size in RowBinary format. [#43842](https://github.com/ClickHouse/ClickHouse/pull/43842) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* - Fix some incorrect logic in ast level optimization related. [#43873](https://github.com/ClickHouse/ClickHouse/pull/43873) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Support query like `SHOW FULL TABLES ...`. [#43910](https://github.com/ClickHouse/ClickHouse/pull/43910) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
* When ClickHouse requests a remote HTTP server, and it returns an error, the numeric HTTP code was not displayed correctly in the exception message. Closes [#43919](https://github.com/ClickHouse/ClickHouse/issues/43919). [#43920](https://github.com/ClickHouse/ClickHouse/pull/43920) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Settings `merge_tree_min_rows_for_concurrent_read_for_remote_filesystem/merge_tree_min_bytes_for_concurrent_read_for_remote_filesystem` did not respect adaptive granularity. Fat rows did not decrease the number of read rows (as it is was done for `merge_tree_min_rows_for_concurrent_read/merge_tree_min_bytes_for_concurrent_read`, which could lead to high memory usage. [#43965](https://github.com/ClickHouse/ClickHouse/pull/43965) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Support `optimize_if_transform_strings_to_enum` in new analyzer. [#43999](https://github.com/ClickHouse/ClickHouse/pull/43999) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* This is to upgrade the new "DeflateQpl" compression codec which has been implemented on previous PR (details: https://github.com/ClickHouse/ClickHouse/pull/39494). This patch improves codec on below aspects: 1. QPL v0.2.0 to QPL v0.3.0 [Intel® Query Processing Library (QPL)](https://github.com/intel/qpl) 2. Improve CMake file for fixing QPL build issues for QPL v0.3.0。 3. Link the QPL library with libaccel-config at build time instead of runtime loading on QPL v0.2.0 (dlopen) 4. Fixed log print issue in CompressionCodecDeflateQpl.cpp. [#44024](https://github.com/ClickHouse/ClickHouse/pull/44024) ([jasperzhu](https://github.com/jinjunzh)).
|
||||
* Follow-up to https://github.com/ClickHouse/ClickHouse/pull/43834 Fix review issues; dependencies from `Distributed` table engine and from `cluster()` function are also considered now; as well as dependencies of a dictionary defined without host & port specified. [#44158](https://github.com/ClickHouse/ClickHouse/pull/44158) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
|
||||
#### Bug Fix
|
||||
* Fix mutations not making progress when checksums do not match between replicas (e.g. caused by a change in data format on an upgrade). [#36877](https://github.com/ClickHouse/ClickHouse/pull/36877) ([nvartolomei](https://github.com/nvartolomei)).
|
||||
* fix skip_unavailable_shards does not work using hdfsCluster table function. [#43236](https://github.com/ClickHouse/ClickHouse/pull/43236) ([chen](https://github.com/xiedeyantu)).
|
||||
* fix s3 support question mark wildcard. Closes [#42731](https://github.com/ClickHouse/ClickHouse/issues/42731). [#43253](https://github.com/ClickHouse/ClickHouse/pull/43253) ([chen](https://github.com/xiedeyantu)).
|
||||
* - Fix functions arrayFirstOrNull and arrayLastOrNull or null when array is Nullable. [#43274](https://github.com/ClickHouse/ClickHouse/pull/43274) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* - we create a new zk path called "async_blocks" for replicated tables in [#43304](https://github.com/ClickHouse/ClickHouse/issues/43304) . However, for tables created in older versions, this path does not exist and will cause error when doing partition operations. This PR will create this node when initializing replicated tree. - This PR created a flag `async_insert_deduplicate` with `false` default value to control whether to use this function. As mentioned in [#38075](https://github.com/ClickHouse/ClickHouse/issues/38075) , this function is not yet fully finished. I would turn off it by default. [#44223](https://github.com/ClickHouse/ClickHouse/pull/44223) ([Han Fei](https://github.com/hanfei1991)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement

|
||||
* Shutdown will be much faster if do not call clearOldPartsFromFilesystem. Especially this is right for tests with zero-copy due to single thread deletion parts. clearOldPartsFromFilesystem is unnecessary after https://github.com/ClickHouse/ClickHouse/pull/41145. [#43760](https://github.com/ClickHouse/ClickHouse/pull/43760) ([Sema Checherinda](https://github.com/CheSema)).

||||
* Fixed unable to log in (because of failure to create session_log entry) in rare case of messed up setting profiles. ... [#42641](https://github.com/ClickHouse/ClickHouse/pull/42641) ([Vasily Nemkov](https://github.com/Enmk)).
|
||||
* Fix incorrect UserTimeMicroseconds/SystemTimeMicroseconds accounting. [#42791](https://github.com/ClickHouse/ClickHouse/pull/42791) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Do not suppress exceptions in web disk. Fix retries for web disk. [#42800](https://github.com/ClickHouse/ClickHouse/pull/42800) ([Azat Khuzhin](https://github.com/azat)).
|

|
||||
* An issue with the following exception has been reported while trying to read a Parquet file from S3 into ClickHouse:. [#43297](https://github.com/ClickHouse/ClickHouse/pull/43297) ([Arthur Passos](https://github.com/arthurpassos)).
|
||||
* Fix bad cast from LowCardinality column when using short circuit function execution. Proper fix of https://github.com/ClickHouse/ClickHouse/pull/42937. [#43311](https://github.com/ClickHouse/ClickHouse/pull/43311) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Fixed queries with `SAMPLE BY` with prewhere optimization on tables using `Merge` engine. [#43315](https://github.com/ClickHouse/ClickHouse/pull/43315) ([Antonio Andelic](https://github.com/antonio2368)).

|
||||
- `unit` — единица измерения времени, в которой будет выражено возвращаемое значение функции. [String](../../sql-reference/data-types/string.md).
|
||||
Возможные значения:
|
||||
|
||||
- `second` (возможные сокращения: `ss`, `s`)
|
||||
- `minute` (возможные сокращения: `mi`, `n`)
|
||||
- `hour` (возможные сокращения: `hh`, `h`)
|
||||
- `day` (возможные сокращения: `dd`, `d`)
|
||||
- `week` (возможные сокращения: `wk`, `ww`)
|
||||
- `month` (возможные сокращения: `mm`, `m`)
|
||||
- `quarter` (возможные сокращения: `qq`, `q`)
|
||||
- `year` (возможные сокращения: `yyyy`, `yy`)
|
||||
|
||||
- `startdate` — первая дата или дата со временем, которая вычитается из `enddate`. [Date](../../sql-reference/data-types/date.md), [Date32](../../sql-reference/data-types/date32.md), [DateTime](../../sql-reference/data-types/datetime.md) или [DateTime64](../../sql-reference/data-types/datetime64.md).
|
||||
|
||||
- `enddate` — вторая дата или дата со временем, из которой вычитается `startdate`. [Date](../../sql-reference/data-types/date.md), [Date32](../../sql-reference/data-types/date32.md), [DateTime](../../sql-reference/data-types/datetime.md) или [DateTime64](../../sql-reference/data-types/datetime64.md).
|
||||
|
||||
- `timezone` — [часовой пояс](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) (необязательно). Если этот аргумент указан, то он применяется как для `startdate`, так и для `enddate`. Если этот аргумент не указан, то используются часовые пояса аргументов `startdate` и `enddate`. Если часовые пояса аргументов `startdate` и `enddate` не совпадают, то результат не определен. [String](../../sql-reference/data-types/string.md).
|
||||
|
||||
**Возвращаемое значение**
|
||||
|
||||
Разница между `enddate` и `startdate`, выраженная в `unit`.

## date\_diff {#date_diff}
|
||||
|
||||
Вычисляет разницу указанных границ `unit` пересекаемых между `startdate` и `enddate`.
|
||||
|
||||
**Синтаксис**
|
||||
|
||||
``` sql
|
||||
date_diff('unit', startdate, enddate, [timezone])
|
||||
```
|
||||
|
||||
Синонимы: `dateDiff`, `DATE_DIFF`.
|
||||
|
||||
**Аргументы**
|
||||
|
||||
- `unit` — единица измерения времени, в которой будет выражено возвращаемое значение функции. [String](../../sql-reference/data-types/string.md).
|
||||
Возможные значения:
|
||||
|
||||
- `second` (возможные сокращения: `ss`, `s`)
|
||||
- `minute` (возможные сокращения: `mi`, `n`)
|
||||
- `hour` (возможные сокращения: `hh`, `h`)
|
||||
- `day` (возможные сокращения: `dd`, `d`)
|
||||
- `week` (возможные сокращения: `wk`, `ww`)
|
||||
- `month` (возможные сокращения: `mm`, `m`)
|
||||
- `quarter` (возможные сокращения: `qq`, `q`)
|
||||
- `year` (возможные сокращения: `yyyy`, `yy`)
|
||||
|
||||
- `startdate` — первая дата или дата со временем, которая вычитается из `enddate`. [Date](../../sql-reference/data-types/date.md), [Date32](../../sql-reference/data-types/date32.md), [DateTime](../../sql-reference/data-types/datetime.md) или [DateTime64](../../sql-reference/data-types/datetime64.md).
|
||||
|
||||
- `enddate` — вторая дата или дата со временем, из которой вычитается `startdate`. [Date](../../sql-reference/data-types/date.md), [Date32](../../sql-reference/data-types/date32.md), [DateTime](../../sql-reference/data-types/datetime.md) или [DateTime64](../../sql-reference/data-types/datetime64.md).
|
||||
|
||||
- `timezone` — [часовой пояс](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) (необязательно). Если этот аргумент указан, то он применяется как для `startdate`, так и для `enddate`. Если этот аргумент не указан, то используются часовые пояса аргументов `startdate` и `enddate`. Если часовые пояса аргументов `startdate` и `enddate` не совпадают, то результат не определен. [String](../../sql-reference/data-types/string.md).
|
||||
|
||||
**Возвращаемое значение**
|
||||
|
||||
Разница между `enddate` и `startdate`, выраженная в `unit`.
|
||||
|
||||
Тип: [Int](../../sql-reference/data-types/int-uint.md).
