### <a id="2212"></a> ClickHouse release 22.12, 2022-12-15 ### <a id="2212"></a> ClickHouse release 22.12, 2022-12-15
#### Upgrade Notes #### 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 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) ([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. * Fixed backward incompatibility in (de)serialization of states of `min`, `max`, `any*`, `argMin`, `argMax` aggregate functions with `String` argument.

#### Performance Improvement #### 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 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. * Add settings `max_streams_for_merge_tree_reading` and `allow_asynchronous_read_from_io_pool_for_merge_tree`.

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 when using remote filesystems.
