### ClickHouse release v22.4.1.2305-prestable FIXME as compared to v22.3.1.1262-prestable
|
|||
|
|
|||
|
#### Backward Incompatible Change
|
|||
|
* Function `yandexConsistentHash` (consistent hashing algorithm by Konstantin "kostik" Oblakov) is renamed to `kostikConsistentHash`. The old name is left as an alias for compatibility. Although this change is backward compatible, we may remove the alias in subsequent releases, that's why it's recommended to update the usages of this function in your apps. [#35553](https://github.com/ClickHouse/ClickHouse/pull/35553) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
|||
|
* Do not allow SETTINGS after FORMAT for INSERT queries (there is compatibility setting `parser_settings_after_format_compact` to accept such queries, but it is turned OFF by default). [#35883](https://github.com/ClickHouse/ClickHouse/pull/35883) ([Azat Khuzhin](https://github.com/azat)).
|
|||
|
* Changed hashed path for cache files. [#36079](https://github.com/ClickHouse/ClickHouse/pull/36079) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
|||
|
|
|||
|
#### New Feature
|
|||
|
* Added support for transactions for simple `MergeTree` tables. This feature is highly experimental and not recommended for production. Part of [#22086](https://github.com/ClickHouse/ClickHouse/issues/22086). [#24258](https://github.com/ClickHouse/ClickHouse/pull/24258) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
|||
|
* Added load balancing setting for [Zoo]Keeper client. Closes [#29617](https://github.com/ClickHouse/ClickHouse/issues/29617). [#30325](https://github.com/ClickHouse/ClickHouse/pull/30325) ([小路](https://github.com/nicelulu)).
|
|||
|
* New aggregation function groupSortedArray to obtain an array of first N values. [#34055](https://github.com/ClickHouse/ClickHouse/pull/34055) ([palegre-tiny](https://github.com/palegre-tiny)).
|
|||
|
* New functions minSampleSizeContinous and minSampleSizeConversion. [#34354](https://github.com/ClickHouse/ClickHouse/pull/34354) ([achimbab](https://github.com/achimbab)).
|
|||
|
* Profiling on Processors level (under `log_processors_profiles` setting, ClickHouse will write time that processor spent during execution/waiting for data to `system.processors_profile_log` table). [#34355](https://github.com/ClickHouse/ClickHouse/pull/34355) ([Azat Khuzhin](https://github.com/azat)).
|
|||
|
* Add `toEndOfMonth` function which rounds up a date or date with time to the last day of the month. [#33501](https://github.com/ClickHouse/ClickHouse/issues/33501). [#34394](https://github.com/ClickHouse/ClickHouse/pull/34394) ([Habibullah Oladepo](https://github.com/holadepo)).
|
|||
|
* Add `h3PointDistM`, `h3PointDistKm`, `h3PointDistRads`, `h3GetRes0Indexes`, `h3GetPentagonIndexes` functions. [#34568](https://github.com/ClickHouse/ClickHouse/pull/34568) ([Bharat Nallan](https://github.com/bharatnc)).
|
|||
|
* Introduce format `ProtobufList`. Fixes [#16436](https://github.com/ClickHouse/ClickHouse/issues/16436). [#35152](https://github.com/ClickHouse/ClickHouse/pull/35152) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

|
|||
|
* Allow to write remote fs cache on all write operations. Add `system.remote_filesystem_cache` table. Add `drop remote filesystem cache` query. Add introspection for s3 metadata with `system.remote_data_paths` table. Closes [#34021](https://github.com/ClickHouse/ClickHouse/issues/34021). Add cache option for merges by adding mode `read_from_filesystem_cache_if_exists_otherwise_bypass_cache` (turned on by default for merges and can also be turned on by query setting with the same name). Rename cache related settings (`remote_fs_enable_cache -> enable_filesystem_cache`, etc). [#35475](https://github.com/ClickHouse/ClickHouse/pull/35475) ([Kseniia Sumarokova](https://github.com/kssenii)).

|
|||
|
* Added function `flattenTuple`. It receives nested named `Tuple` as an argument and returns a flatten `Tuple` which elements are the paths from the original `Tuple`. E.g.: `Tuple(a Int, Tuple(b Int, c Int)) -> Tuple(a Int, b Int, c Int)`. `flattenTuple` can be used to select all paths from type `Object` as separate columns. [#35690](https://github.com/ClickHouse/ClickHouse/pull/35690) ([Anton Popov](https://github.com/CurtizJ)).
|
|||
|

|
|||
|
* Adding random salt and appending to password to generate password hash. [#36172](https://github.com/ClickHouse/ClickHouse/pull/36172) ([Rajkumar Varada](https://github.com/varadarajkumar)).

|
|||
|
* Implement type inference for INSERT INTO function null(). Closes [#36334](https://github.com/ClickHouse/ClickHouse/issues/36334). [#36353](https://github.com/ClickHouse/ClickHouse/pull/36353) ([flynn](https://github.com/ucasfl)).

|
|||
|
|
|||
|
#### Performance Improvement
|
|||
|
* Speed up parts loading process of MergeTree to accelerate starting up of clickhouse-server. With this improvement, clickhouse-server was able to decrease starting up time from 75 minutes to 20 seconds, with 700k mergetree parts. [#32928](https://github.com/ClickHouse/ClickHouse/pull/32928) ([李扬](https://github.com/taiyang-li)).
|
|||
|
* Sizes of hash tables used during aggregation now collected and used in later queries to avoid hash tables resizes. [#33439](https://github.com/ClickHouse/ClickHouse/pull/33439) ([Nikita Taranov](https://github.com/nickitat)).
|
|||
|
* Multiple changes to improve ASOF join performance (1.2 - 1.6x as fast). It also adds support to use big integers. [#34733](https://github.com/ClickHouse/ClickHouse/pull/34733) ([Raúl Marín](https://github.com/Algunenano)).
|
|||
|
* URL storage engine now downloads multiple chunks in parallel if the endpoint supports HTTP Range. Two additional settings were added, `max_download_threads` and `max_download_buffer_size`, which control maximum number of threads a single query can use to download the file and the maximum number of bytes each thread can process. [#35150](https://github.com/ClickHouse/ClickHouse/pull/35150) ([Antonio Andelic](https://github.com/antonio2368)).
|
|||
|
* parallelization of multipart upload into S3 storage. [#35343](https://github.com/ClickHouse/ClickHouse/pull/35343) ([Sergei Trifonov](https://github.com/serxa)).
|
|||
|
* Improve performance of ASOF JOIN if key is native integer. [#35525](https://github.com/ClickHouse/ClickHouse/pull/35525) ([Maksim Kita](https://github.com/kitaisreal)).
|
|||
|
* A new query plan optimization. Evaluate functions after `ORDER BY` when possible. As an example, for a query `SELECT sipHash64(number) FROM numbers(1e8) ORDER BY number LIMIT 5`, function `sipHash64` would be evaluated after `ORDER BY` and `LIMIT`, which gives ~20x speed up. [#35623](https://github.com/ClickHouse/ClickHouse/pull/35623) ([Nikita Taranov](https://github.com/nickitat)).
|
|||
|
* narrow mutex scope when setenv LIBHDFS3_CONF related issue [#35292](https://github.com/ClickHouse/ClickHouse/issues/35292). [#35646](https://github.com/ClickHouse/ClickHouse/pull/35646) ([shuchaome](https://github.com/shuchaome)).
|
|||
|
* Improve performance of `hasAll` function using specializations for SSE and AVX2. Author @youennL-cs. [#35723](https://github.com/ClickHouse/ClickHouse/pull/35723) ([Maksim Kita](https://github.com/kitaisreal)).
|
|||
|
* - The explain statement of GLOBAL JOIN two distributed tables can speed up 100x: explain plan select ... from t1_dist global join t2_dist on ... explain pipeline select ... from t1_dist global join t2_dist on ... [#36055](https://github.com/ClickHouse/ClickHouse/pull/36055) ([何李夫](https://github.com/helifu)).
|
|||
|
* 2 optimizations: - Optimize trivail count hive query - Speed up hive query by caching metadata of hive file. [#36082](https://github.com/ClickHouse/ClickHouse/pull/36082) ([李扬](https://github.com/taiyang-li)).
|
|||
|
|
|||
|
#### Improvement

|
|||
|
* As talked in [issue 27025](https://github.com/ClickHouse/ClickHouse/issues/27025), there is an improvement of the HasAll function using SIMD instruction (SSE and AVX2). Gtest tests have also been added. [#27653](https://github.com/ClickHouse/ClickHouse/pull/27653) ([youennL-cs](https://github.com/youennL-cs)).
|
|||
|
* Proper support of setting `max_rows_to_read` in case of reading in order of sorting key and specified limit. Previously the exception `Limit for rows or bytes to read exceeded` could be thrown even if query actually requires to read less amount of rows. [#33230](https://github.com/ClickHouse/ClickHouse/pull/33230) ([Anton Popov](https://github.com/CurtizJ)).
|
|||
|
* INTERVAL improvement - can be used with `[MILLI|MICRO|NANO]SECOND`. Added `toStartOf[Milli|Micro|Nano]second()` functions. Added `[add|subtract][Milli|Micro|Nano]second()`. [#34353](https://github.com/ClickHouse/ClickHouse/pull/34353) ([Andrey Zvonov](https://github.com/zvonand)).
|
|||
|
* System log tables allow to specify COMMENT in ENGINE declaration. Closes [#33768](https://github.com/ClickHouse/ClickHouse/issues/33768). [#34536](https://github.com/ClickHouse/ClickHouse/pull/34536) ([Maksim Kita](https://github.com/kitaisreal)).

|
|||
|
* If `port` is not specified in cluster configuration, default server port will be used. This closes [#34769](https://github.com/ClickHouse/ClickHouse/issues/34769). [#34772](https://github.com/ClickHouse/ClickHouse/pull/34772) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
|||
|
* Added better error messages in case of connection failed to MySQL. Closes [#35128](https://github.com/ClickHouse/ClickHouse/issues/35128). [#35234](https://github.com/ClickHouse/ClickHouse/pull/35234) ([zzsmdfj](https://github.com/zzsmdfj)).
|
|||
|
* Add function `getTypeSerializationStreams`. For a specified type (which is detected from column), it returns an array with all the serialization substream paths. This function is useful mainly for developers. [#35290](https://github.com/ClickHouse/ClickHouse/pull/35290) ([李扬](https://github.com/taiyang-li)).
|
|||
|
* - wchc operation is expensive and should not be in the four_letter_word_white_list defaults. [#35320](https://github.com/ClickHouse/ClickHouse/pull/35320) ([zhangyuli1](https://github.com/zhangyuli1)).

|
|||
|
* Add a new kind of row policies named `simple`. Before this PR we had two kinds or row policies: `permissive` and `restrictive`. A `simple` row policy adds a new filter on a table without any side-effects like it was for permissive and restrictive policies. [#35345](https://github.com/ClickHouse/ClickHouse/pull/35345) ([Vitaly Baranov](https://github.com/vitlibar)).
|
|||
|
* Remove testmode option, enable it unconditionally. [#35354](https://github.com/ClickHouse/ClickHouse/pull/35354) ([Kseniia Sumarokova](https://github.com/kssenii)).

|
|||
|
* fix INSERT INTO table FROM INFILE does not display progress bar. [#35429](https://github.com/ClickHouse/ClickHouse/pull/35429) ([xiedeyantu](https://github.com/xiedeyantu)).
|
|||
|
* Allow server to bind to low-numbered ports (e.g. 443). ClickHouse installation script will set `cap_net_bind_service` to the binary file. [#35451](https://github.com/ClickHouse/ClickHouse/pull/35451) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
|||
|
* Add settings `input_format_orc_case_insensitive_column_matching`, `input_format_arrow_case_insensitive_column_matching`, and `input_format_parquet_case_insensitive_column_matching` which allows ClickHouse to use case insensitive matching of columns while reading data from ORC, Arrow or Parquet files. [#35459](https://github.com/ClickHouse/ClickHouse/pull/35459) ([Antonio Andelic](https://github.com/antonio2368)).
|
|||
|
* - Add explicit table info to the scan node of query plan and pipeline. [#35460](https://github.com/ClickHouse/ClickHouse/pull/35460) ([何李夫](https://github.com/helifu)).
|
|||
|
* Propagate query and session settings for distributed DDL queries. Setting `distributed_ddl_entry_format_version` is set to 2 by default now. [#35463](https://github.com/ClickHouse/ClickHouse/pull/35463) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
|||
|
* Add sizes of subcolumns to `system.parts_columns` table. [#35488](https://github.com/ClickHouse/ClickHouse/pull/35488) ([Anton Popov](https://github.com/CurtizJ)).
|
|||
|
* It was possible to get stack overflow in distributed queries if one of the settings `async_socket_for_remote` and `use_hedged_requests` is enabled while parsing very deeply nested data type (at least in debug build). Closes [#35509](https://github.com/ClickHouse/ClickHouse/issues/35509). [#35524](https://github.com/ClickHouse/ClickHouse/pull/35524) ([Kruglov Pavel](https://github.com/Avogar)).
|
|||
|
* Improve pasting performance and compatibility of clickhouse-client. This helps [#35501](https://github.com/ClickHouse/ClickHouse/issues/35501). [#35541](https://github.com/ClickHouse/ClickHouse/pull/35541) ([Amos Bird](https://github.com/amosbird)).
|
|||
|
* Added a support for automatic schema inference to `s3Cluster` table function. Synced the signatures of `s3 ` and `s3Cluster`. [#35544](https://github.com/ClickHouse/ClickHouse/pull/35544) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
|||
|
* Use multiple threads to download objects from S3. Downloading is controllable using `max_download_threads` and `max_download_buffer_size` settings. [#35571](https://github.com/ClickHouse/ClickHouse/pull/35571) ([Antonio Andelic](https://github.com/antonio2368)).
|
|||
|
* Deduce absolute hdfs config path. [#35572](https://github.com/ClickHouse/ClickHouse/pull/35572) ([李扬](https://github.com/taiyang-li)).
|
|||
|
* - Use some tweaks and heuristics to determine numbers, strings, arrays, tuples and maps in CSV, TSV and TSVRaw data formats. Add setting `input_format_csv_use_best_effort_in_schema_inference` for CSV format that enables/disables using these heuristics, if it's disabled, we treat everything as string. Add similar setting `input_format_tsv_use_best_effort_in_schema_inference` for TSV/TSVRaw format. These settings are enabled by default. - Add Maps support for schema inference in Values format. - Fix possible segfault in schema inference in Values format. - Allow to skip columns with unsupported types in Arrow/ORC/Parquet formats. Add corresponding settings for it: `input_format_{parquet|orc|arrow}_skip_columns_with_unsupported_types_in_schema_inference`. These settings are disabled by default. - Allow to convert a column with type Null to a Nullable column with all NULL values in Arrow/Parquet formats. - Allow to specify column names in schema inference via setting `column_names_for_schema_inference` for formats that don't contain column names (like CSV, TSV, JSONCompactEachRow, etc) - Fix schema inference in ORC/Arrow/Parquet formats in terms of working with Nullable columns. Previously all inferred types were not Nullable and it blocked reading Nullable columns from data, now it's fixed and all inferred types are always Nullable (because we cannot understand that column is Nullable or not by reading the schema). - Fix schema inference in Template format with CSV escaping rules. [#35582](https://github.com/ClickHouse/ClickHouse/pull/35582) ([Kruglov Pavel](https://github.com/Avogar)).
|
|||
|
* Add parallel parsing and schema inference for format `JSONAsObject`. [#35592](https://github.com/ClickHouse/ClickHouse/pull/35592) ([Anton Popov](https://github.com/CurtizJ)).
|
|||
|
* Added support for schema inference for `hdfsCluster`. [#35602](https://github.com/ClickHouse/ClickHouse/pull/35602) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
|||
|
* - Improve the pipeline description for JOIN. [#35612](https://github.com/ClickHouse/ClickHouse/pull/35612) ([何李夫](https://github.com/helifu)).

|
|||
|
* Add profile event counter `AsyncInsertBytes` about size of async INSERTs. [#35644](https://github.com/ClickHouse/ClickHouse/pull/35644) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
|||
|
* Added `is_secure` column to `system.query_log` which denotes if the client is using a secure connection over TCP or HTTP. [#35705](https://github.com/ClickHouse/ClickHouse/pull/35705) ([Antonio Andelic](https://github.com/antonio2368)).
|
|||

|
|||
|
* Improve columns ordering in schema inference for formats TSKV and JSONEachRow, closes [#35640](https://github.com/ClickHouse/ClickHouse/issues/35640). Don't stop schema inference when reading empty row in schema inference for formats TSKV and JSONEachRow. [#35724](https://github.com/ClickHouse/ClickHouse/pull/35724) ([Kruglov Pavel](https://github.com/Avogar)).
|
|||
|
* Add new setting `input_format_json_read_bools_as_numbers` that allows to infer and parse bools as numbers in JSON input formats. It's enabled by default. Suggested by @alexey-milovidov. [#35735](https://github.com/ClickHouse/ClickHouse/pull/35735) ([Kruglov Pavel](https://github.com/Avogar)).
|
|||
|
* Respect remote_url_allow_hosts for hive. [#35743](https://github.com/ClickHouse/ClickHouse/pull/35743) ([李扬](https://github.com/taiyang-li)).
|
|||
|
* Support schema inference for insert select with using `input` table function. Get schema from insertion table instead of inferring it from the data in case of insert select from table functions that support schema inference. Closes [#35639](https://github.com/ClickHouse/ClickHouse/issues/35639). [#35760](https://github.com/ClickHouse/ClickHouse/pull/35760) ([Kruglov Pavel](https://github.com/Avogar)).
|
|||
|
* Improve projection analysis to optimize trivial queries such as `count()`. [#35788](https://github.com/ClickHouse/ClickHouse/pull/35788) ([Amos Bird](https://github.com/amosbird)).
|

* support ALTER TABLE t DETACH PARTITION (ALL). [#35794](https://github.com/ClickHouse/ClickHouse/pull/35794) ([awakeljw](https://github.com/awakeljw)).
|
|||
|
* Added an animation to the hourglass icon to indicate to the user that a query is running. [#35860](https://github.com/ClickHouse/ClickHouse/pull/35860) ([peledni](https://github.com/peledni)).
|
|||
|
* Now some `ALTER MODIFY COLUMN` queries for `Arrays` and `Nullable` types can be done at metadata level without mutations. For example, alter from `Array(Enum8('Option1'=1))` to `Array(Enum8('Option1'=1, 'Option2'=2))`. [#35882](https://github.com/ClickHouse/ClickHouse/pull/35882) ([alesapin](https://github.com/alesapin)).
|
|||
|
* Now it's not allowed to `ALTER TABLE ... RESET SETTING` for non-existing settings for MergeTree engines family. Fixes [#35816](https://github.com/ClickHouse/ClickHouse/issues/35816). [#35884](https://github.com/ClickHouse/ClickHouse/pull/35884) ([alesapin](https://github.com/alesapin)).
