### <a id="229"></a> ClickHouse release 22.9, 2022-09-22
#### Backward Incompatible Change
* Upgrade from 20.3 and older to 22.9 and newer should be done through an intermediate version if there are any `ReplicatedMergeTree` tables, otherwise server with the new version will not start. [#40641](https://github.com/ClickHouse/ClickHouse/pull/40641) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Remove the functions `accurate_Cast` and `accurate_CastOrNull` (they are different to `accurateCast` and `accurateCastOrNull` by underscore in the name and they are not affected by the value of `cast_keep_nullable` setting). These functions were undocumented, untested, unused, and unneeded. They appeared to be alive due to code generalization. [#40682](https://github.com/ClickHouse/ClickHouse/pull/40682) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add a test to ensure that every new table function will be documented. See [#40649](https://github.com/ClickHouse/ClickHouse/issues/40649). Rename table function `MeiliSearch` to `meilisearch`. [#40709](https://github.com/ClickHouse/ClickHouse/pull/40709) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add a test to ensure that every new function will be documented. See [#40649](https://github.com/ClickHouse/ClickHouse/pull/40649). The functions `lemmatize`, `synonyms`, `stem` were case-insensitive by mistake. Now they are case-sensitive. [#40711](https://github.com/ClickHouse/ClickHouse/pull/40711) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Make interpretation of YAML configs to be more conventional. [#41044](https://github.com/ClickHouse/ClickHouse/pull/41044) ([Vitaly Baranov](https://github.com/vitlibar)).
#### New Feature
* Support `insert_quorum = 'auto'` to use majority number. [#39970](https://github.com/ClickHouse/ClickHouse/pull/39970) ([Sachin](https://github.com/SachinSetiya)).
* Add embedded dashboards to ClickHouse server. This is a demo project about how to achieve 90% results with 1% effort using ClickHouse features. [#40461](https://github.com/ClickHouse/ClickHouse/pull/40461) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Added new settings constraint writability kind `changeable_in_readonly`. [#40631](https://github.com/ClickHouse/ClickHouse/pull/40631) ([Sergei Trifonov](https://github.com/serxa)).
* Add support for `INTERSECT DISTINCT` and `EXCEPT DISTINCT`. [#40792](https://github.com/ClickHouse/ClickHouse/pull/40792) ([Duc Canh Le](https://github.com/canhld94)).
* Add new input/output format `JSONObjectEachRow` - Support import for formats `JSON/JSONCompact/JSONColumnsWithMetadata`. Add new setting `input_format_json_validate_types_from_metadata` that controls whether we should check if data types from metadata match data types from the header. - Add new setting `input_format_json_validate_utf8`, when it's enabled, all `JSON` formats will validate UTF-8 sequences. It will be disabled by default. Note that this setting doesn't influence output formats `JSON/JSONCompact/JSONColumnsWithMetadata`, they always validate utf8 sequences (this exception was made because of compatibility reasons). - Add new setting `input_format_json_read_numbers_as_strings ` that allows to parse numbers in String column, the setting is disabled by default. - Add new setting `output_format_json_quote_decimals` that allows to output decimals in double quotes, disabled by default. - Allow to parse decimals in double quotes during data import. [#40910](https://github.com/ClickHouse/ClickHouse/pull/40910) ([Kruglov Pavel](https://github.com/Avogar)).
* Query parameters supported in DESCRIBE TABLE query. [#40952](https://github.com/ClickHouse/ClickHouse/pull/40952) ([Nikita Taranov](https://github.com/nickitat)).
* Add support to Parquet Time32/64 by converting it into DateTime64. Parquet time32/64 represents time elapsed since midnight, while DateTime32/64 represents an actual unix timestamp. Conversion simply offsets from `0`. [#41333](https://github.com/ClickHouse/ClickHouse/pull/41333) ([Arthur Passos](https://github.com/arthurpassos)).
* Implement set operations on Apache Datasketches. [#39919](https://github.com/ClickHouse/ClickHouse/pull/39919) ([Fangyuan Deng](https://github.com/pzhdfy)). Note: there is no point of using Apache Datasketches, they are inferiour than ClickHouse and only make sense for integration with other systems.
* Allow recording errors to specified file while reading text formats (`CSV`, `TSV`). [#40516](https://github.com/ClickHouse/ClickHouse/pull/40516) ([zjial](https://github.com/zjial)).
#### Experimental Feature
* Add ANN (approximate nearest neighbor) index based on `Annoy`. [#40818](https://github.com/ClickHouse/ClickHouse/pull/40818) ([Filatenkov Artur](https://github.com/FArthur-cmd)). [#37215](https://github.com/ClickHouse/ClickHouse/pull/37215) ([VVMak](https://github.com/VVMak)).
* Add new storage engine `KeeperMap`, that uses ClickHouse Keeper or ZooKeeper as a key-value store. [#39976](https://github.com/ClickHouse/ClickHouse/pull/39976) ([Antonio Andelic](https://github.com/antonio2368)). This storage engine is intended to store a small amount of metadata.
* Improvement for in-memory data parts: remove completely processed WAL files. [#40592](https://github.com/ClickHouse/ClickHouse/pull/40592) ([Azat Khuzhin](https://github.com/azat)).
#### Performance Improvement
* Implement compression of marks and primary key. Close [#34437](https://github.com/ClickHouse/ClickHouse/issues/34437). [#37693](https://github.com/ClickHouse/ClickHouse/pull/37693) ([zhongyuankai](https://github.com/zhongyuankai)).
* Allow to load marks with threadpool in advance. Regulated by setting `load_marks_asynchronously` (default: 0). [#40821](https://github.com/ClickHouse/ClickHouse/pull/40821) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Virtual filesystem over s3 will use random object names split into multiple path prefixes for better performance on AWS. [#40968](https://github.com/ClickHouse/ClickHouse/pull/40968) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Account `max_block_size` value while producing single-level aggregation results. Allows to execute following query plan steps using more threads. [#39138](https://github.com/ClickHouse/ClickHouse/pull/39138) ([Nikita Taranov](https://github.com/nickitat)).
* Software prefetching is used in aggregation to speed up operations with hash tables. Controlled by the setting `enable_software_prefetch_in_aggregation`, enabled by default. [#39304](https://github.com/ClickHouse/ClickHouse/pull/39304) ([Nikita Taranov](https://github.com/nickitat)).
* Better support of `optimize_read_in_order` in case when some of sorting key columns are always constant after applying `WHERE` clause. E.g. query like `SELECT ... FROM table WHERE a = 'x' ORDER BY a, b`, where `table` has storage definition: `MergeTree ORDER BY (a, b)`. [#38715](https://github.com/ClickHouse/ClickHouse/pull/38715) ([Anton Popov](https://github.com/CurtizJ)).
* Filter joined streams for `full_sorting_join` by each other before sorting. [#39418](https://github.com/ClickHouse/ClickHouse/pull/39418) ([Vladimir C](https://github.com/vdimir)).
* LZ4 decompression optimised by skipping empty literals processing. [#40142](https://github.com/ClickHouse/ClickHouse/pull/40142) ([Nikita Taranov](https://github.com/nickitat)).
* Speedup backup process using native `copy` when possible instead of copying through `clickhouse-server` memory. [#40395](https://github.com/ClickHouse/ClickHouse/pull/40395) ([alesapin](https://github.com/alesapin)).
* Do not obtain storage snapshot for each INSERT block (slightly improves performance). [#40638](https://github.com/ClickHouse/ClickHouse/pull/40638) ([Azat Khuzhin](https://github.com/azat)).
* Implement batch processing for aggregate functions with multiple nullable arguments. [#41058](https://github.com/ClickHouse/ClickHouse/pull/41058) ([Raúl Marín](https://github.com/Algunenano)).
* Speed up reading UniquesHashSet (`uniqState` from disk for example). [#41089](https://github.com/ClickHouse/ClickHouse/pull/41089) ([Raúl Marín](https://github.com/Algunenano)).
* Fixed high memory usage while executing mutations of compact parts in tables with huge number of columns. [#41122](https://github.com/ClickHouse/ClickHouse/pull/41122) ([lthaooo](https://github.com/lthaooo)).
* Enable the vectorscan library on ARM, this speeds up regexp evaluation. [#41033](https://github.com/ClickHouse/ClickHouse/pull/41033) ([Robert Schulze](https://github.com/rschu1ze)).
* Upgrade vectorscan to 5.4.8 which has many performance optimizations to speed up regexp evaluation. [#41270](https://github.com/ClickHouse/ClickHouse/pull/41270) ([Robert Schulze](https://github.com/rschu1ze)).
* Fix incorrect fallback to skip the local filesystem cache for VFS (like S3) which happened on very high concurrency level. [#40420](https://github.com/ClickHouse/ClickHouse/pull/40420) ([Kseniia Sumarokova](https://github.com/kssenii)).
* If row policy filter is always false, return empty result immediately without reading any data. This closes [#24012](https://github.com/ClickHouse/ClickHouse/issues/24012). [#40740](https://github.com/ClickHouse/ClickHouse/pull/40740) ([Amos Bird](https://github.com/amosbird)).
* Parallel hash JOIN for Float data types might be suboptimal. Make it better. [#41183](https://github.com/ClickHouse/ClickHouse/pull/41183) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
#### Improvement
* During startup and ATTACH call, `ReplicatedMergeTree` tables will be readonly until the ZooKeeper connection is made and the setup is finished. [#40148](https://github.com/ClickHouse/ClickHouse/pull/40148) ([Antonio Andelic](https://github.com/antonio2368)).
* Add `enable_extended_results_for_datetime_functions` option to return results of type Date32 for functions toStartOfYear, toStartOfISOYear, toStartOfQuarter, toStartOfMonth, toStartOfWeek, toMonday and toLastDayOfMonth when argument is Date32 or DateTime64, otherwise results of Date type are returned. For compatibility reasons default value is ‘0’. [#41214](https://github.com/ClickHouse/ClickHouse/pull/41214) ([Roman Vasin](https://github.com/rvasin)).
* For security and stability reasons, CatBoost models are no longer evaluated within the ClickHouse server. Instead, the evaluation is now done in the clickhouse-library-bridge, a separate process that loads the catboost library and communicates with the server process via HTTP. [#40897](https://github.com/ClickHouse/ClickHouse/pull/40897) ([Robert Schulze](https://github.com/rschu1ze)). [#39629](https://github.com/ClickHouse/ClickHouse/pull/39629) ([Robert Schulze](https://github.com/rschu1ze)).
* Add more metrics for on-disk temporary data, close [#40206](https://github.com/ClickHouse/ClickHouse/issues/40206). [#40239](https://github.com/ClickHouse/ClickHouse/pull/40239) ([Vladimir C](https://github.com/vdimir)).

* Allow minimal `clickhouse-local` build by correcting some dependencies. [#40460](https://github.com/ClickHouse/ClickHouse/pull/40460) ([Alexey Milovidov](https://github.com/alexey-milovidov)). It is less than 50 MiB.
* Calculate and report SQL function coverage in tests. [#40593](https://github.com/ClickHouse/ClickHouse/issues/40593). [#40647](https://github.com/ClickHouse/ClickHouse/pull/40647) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Enforce documentation for every MergeTree setting. [#40648](https://github.com/ClickHouse/ClickHouse/pull/40648) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* A prototype of embedded reference documentation for high-level uniform server components. [#40649](https://github.com/ClickHouse/ClickHouse/pull/40649) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* We will check all queries from the changed perf tests to ensure that all changed queries were tested. [#40322](https://github.com/ClickHouse/ClickHouse/pull/40322) ([Nikita Taranov](https://github.com/nickitat)).

* Switch to llvm/clang 15. [#41046](https://github.com/ClickHouse/ClickHouse/pull/41046) ([Azat Khuzhin](https://github.com/azat)).
* Continuation of [#40938](https://github.com/ClickHouse/ClickHouse/issues/40938). Fix ODR violation for `Loggers` class. Fixes [#40398](https://github.com/ClickHouse/ClickHouse/issues/40398), [#40937](https://github.com/ClickHouse/ClickHouse/issues/40937). [#41060](https://github.com/ClickHouse/ClickHouse/pull/41060) ([Dmitry Novik](https://github.com/novikd)).
* Add macOS binaries to GitHub release assets, it fixes [#37718](https://github.com/ClickHouse/ClickHouse/issues/37718). [#41088](https://github.com/ClickHouse/ClickHouse/pull/41088) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* The c-ares library is now bundled with ClickHouse's build system. [#41239](https://github.com/ClickHouse/ClickHouse/pull/41239) ([Robert Schulze](https://github.com/rschu1ze)).
* Get rid of `dlopen` from the main ClickHouse code. It remains in the library-bridge and odbc-bridge. [#41428](https://github.com/ClickHouse/ClickHouse/pull/41428) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Don't allow `dlopen` in the main ClickHouse binary, because it is harmful and insecure. We don't use it. But it can be used by some libraries for the implementation of "plugins".
