### <a id="2211"></a> ClickHouse release 22.11, 2022-11-17
#### Backward Incompatible Change
* `JSONExtract` family of functions will now attempt to coerce to the requested type. [#41502](https://github.com/ClickHouse/ClickHouse/pull/41502) ([Márcio Martins](https://github.com/marcioapm)).
#### New Feature
* Adds support for retries during INSERTs into ReplicatedMergeTree when a session with ClickHouse Keeper is lost. Apart from fault tolerance, it aims to provide better user experience, - avoid returning a user an error during insert if keeper is restarted (for example, due to upgrade). This is controlled by the `insert_keeper_max_retries` setting, which is disabled by default. [#42607](https://github.com/ClickHouse/ClickHouse/pull/42607) ([Igor Nikonov](https://github.com/devcrafter)).
* Add `Hudi` and `DeltaLake` table engines, read-only, only for tables on S3. [#41054](https://github.com/ClickHouse/ClickHouse/pull/41054) ([Daniil Rubin](https://github.com/rubin-do), [Kseniia Sumarokova](https://github.com/kssenii)).
* Add table function `hudi` and `deltaLake`. [#43080](https://github.com/ClickHouse/ClickHouse/pull/43080) ([flynn](https://github.com/ucasfl)).
* Support for composite time intervals. 1. Add, subtract and negate operations are now available on Intervals. In the case where the types of Intervals are different, they will be transformed into the Tuple of those types. 2. A tuple of intervals can be added to or subtracted from a Date/DateTime field. 3. Added parsing of Intervals with different types, for example: `INTERVAL '1 HOUR 1 MINUTE 1 SECOND'`. [#42195](https://github.com/ClickHouse/ClickHouse/pull/42195) ([Nikolay Degterinsky](https://github.com/evillique)).
* Added `**` glob support for recursive directory traversal of the filesystem and S3. Resolves [#36316](https://github.com/ClickHouse/ClickHouse/issues/36316). [#42376](https://github.com/ClickHouse/ClickHouse/pull/42376) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
* Introduce `s3_plain` disk type for write-once-read-many operations. Implement `ATTACH` of `MergeTree` table for `s3_plain` disk. [#42628](https://github.com/ClickHouse/ClickHouse/pull/42628) ([Azat Khuzhin](https://github.com/azat)).
* Added applied row-level policies to `system.query_log`. [#39819](https://github.com/ClickHouse/ClickHouse/pull/39819) ([Vladimir Chebotaryov](https://github.com/quickhouse)).
* Add four-letter command `csnp` for manually creating snapshots in ClickHouse Keeper. Additionally, `lgif` was added to get Raft information for a specific node (e.g. index of last created snapshot, last committed log index). [#41766](https://github.com/ClickHouse/ClickHouse/pull/41766) ([JackyWoo](https://github.com/JackyWoo)).
* Add function `ascii` like in Apache Spark: https://spark.apache.org/docs/latest/api/sql/#ascii. [#42670](https://github.com/ClickHouse/ClickHouse/pull/42670) ([李扬](https://github.com/taiyang-li)).
* Add function `positive_modulo` (`pmod`) which returns non-negative result based on modulo. [#42755](https://github.com/ClickHouse/ClickHouse/pull/42755) ([李扬](https://github.com/taiyang-li)).
* Add function `formatReadableDecimalSize`. [#42774](https://github.com/ClickHouse/ClickHouse/pull/42774) ([Alejandro](https://github.com/alexon1234)).
* Add function `randCanonical`, which is similar to the `rand` function in Apache Spark or Impala. The function generates pseudo random results with independent and identically distributed uniformly distributed values in [0, 1). [#43124](https://github.com/ClickHouse/ClickHouse/pull/43124) ([李扬](https://github.com/taiyang-li)).
* Add function `displayName`, closes [#36770](https://github.com/ClickHouse/ClickHouse/issues/36770). [#37681](https://github.com/ClickHouse/ClickHouse/pull/37681) ([hongbin](https://github.com/xlwh)).
* Add `min_age_to_force_merge_on_partition_only` setting to optimize old parts for the entire partition only. [#42659](https://github.com/ClickHouse/ClickHouse/pull/42659) ([Antonio Andelic](https://github.com/antonio2368)).
* Add generic implementation for arbitrary structured named collections, access type and `system.named_collections`. [#43147](https://github.com/ClickHouse/ClickHouse/pull/43147) ([Kseniia Sumarokova](https://github.com/kssenii)).
#### Performance Improvement
* Parallelized merging of `uniqExact` states for aggregation without key, i.e. queries like `SELECT uniqExact(number) FROM table`. The improvement becomes noticeable when the number of unique keys approaches 10^6. Also `uniq` performance is slightly optimized. [#43072](https://github.com/ClickHouse/ClickHouse/pull/43072) ([Nikita Taranov](https://github.com/nickitat)).
* `match` function can use the index if it's a condition on string prefix. This closes [#37333](https://github.com/ClickHouse/ClickHouse/issues/37333). [#42458](https://github.com/ClickHouse/ClickHouse/pull/42458) ([clarkcaoliu](https://github.com/Clark0)).
* Speed up AND and OR operators when they are sequenced. [#42214](https://github.com/ClickHouse/ClickHouse/pull/42214) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
* Support parallel parsing for `LineAsString` input format. This improves performance just slightly. This closes [#42502](https://github.com/ClickHouse/ClickHouse/issues/42502). [#42780](https://github.com/ClickHouse/ClickHouse/pull/42780) ([Kruglov Pavel](https://github.com/Avogar)).
* ClickHouse Keeper performance improvement: improve commit performance for cases when many different nodes have uncommitted states. This should help with cases when a follower node can't sync fast enough. [#42926](https://github.com/ClickHouse/ClickHouse/pull/42926) ([Antonio Andelic](https://github.com/antonio2368)).
* A condition like `NOT LIKE 'prefix%'` can use the primary index. [#42209](https://github.com/ClickHouse/ClickHouse/pull/42209) ([Duc Canh Le](https://github.com/canhld94)).
#### Experimental Feature
* Support type `Object` inside other types, e.g. `Array(JSON)`. [#36969](https://github.com/ClickHouse/ClickHouse/pull/36969) ([Anton Popov](https://github.com/CurtizJ)).
* Ignore MySQL binlog SAVEPOINT event for MaterializedMySQL. [#42931](https://github.com/ClickHouse/ClickHouse/pull/42931) ([zzsmdfj](https://github.com/zzsmdfj)). Handle (ignore) SAVEPOINT queries in MaterializedMySQL. [#43086](https://github.com/ClickHouse/ClickHouse/pull/43086) ([Stig Bakken](https://github.com/stigsb)).
#### Improvement
* Trivial queries with small LIMIT will properly determine the number of estimated rows to read, so that the threshold will be checked properly. Closes [#7071](https://github.com/ClickHouse/ClickHouse/issues/7071). [#42580](https://github.com/ClickHouse/ClickHouse/pull/42580) ([Han Fei](https://github.com/hanfei1991)).
* Add support for interactive parameters in INSERT VALUES queries. [#43077](https://github.com/ClickHouse/ClickHouse/pull/43077) ([Nikolay Degterinsky](https://github.com/evillique)).
* Added new field `allow_readonly` in `system.table_functions` to allow using table functions in readonly mode. Resolves [#42414](https://github.com/ClickHouse/ClickHouse/issues/42414) Implementation: * Added a new field allow_readonly to table system.table_functions. * Updated to use new field allow_readonly to allow using table functions in readonly mode. Testing: * Added a test for filesystem tests/queries/0_stateless/02473_functions_in_readonly_mode.sh Documentation: * Updated the english documentation for Table Functions. [#42708](https://github.com/ClickHouse/ClickHouse/pull/42708) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
* The `system.asynchronous_metrics` gets embedded documentation. This documentation is also exported to Prometheus. Fixed an error with the metrics about `cache` disks - they were calculated only for one arbitrary cache disk instead all of them. This closes [#7644](https://github.com/ClickHouse/ClickHouse/issues/7644). [#43194](https://github.com/ClickHouse/ClickHouse/pull/43194) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Throttling algorithm changed to token bucket. [#42665](https://github.com/ClickHouse/ClickHouse/pull/42665) ([Sergei Trifonov](https://github.com/serxa)).
* Mask passwords and secret keys both in `system.query_log` and `/var/log/clickhouse-server/*.log` and also in error messages. [#42484](https://github.com/ClickHouse/ClickHouse/pull/42484) ([Vitaly Baranov](https://github.com/vitlibar)).
* Remove covered parts for fetched part (to avoid possible replication delay grows). [#39737](https://github.com/ClickHouse/ClickHouse/pull/39737) ([Azat Khuzhin](https://github.com/azat)).
* If `/dev/tty` is available, the progress in clickhouse-client and clickhouse-local will be rendered directly to the terminal, without writing to STDERR. It allows getting progress even if STDERR is redirected to a file, and the file will not be polluted by terminal escape sequences. The progress can be disabled by `--progress false`. This closes [#32238](https://github.com/ClickHouse/ClickHouse/issues/32238). [#42003](https://github.com/ClickHouse/ClickHouse/pull/42003) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

* Add columns `bytes_on_disk` and `path` to `system.detached_parts`. Closes [#42264](https://github.com/ClickHouse/ClickHouse/issues/42264). [#42303](https://github.com/ClickHouse/ClickHouse/pull/42303) ([chen](https://github.com/xiedeyantu)).
* Improve using structure from insertion table in table functions, now setting `use_structure_from_insertion_table_in_table_functions` has new possible value - `2` that means that ClickHouse will try to determine if we can use structure from insertion table or not automatically. Closes [#40028](https://github.com/ClickHouse/ClickHouse/issues/40028). [#42320](https://github.com/ClickHouse/ClickHouse/pull/42320) ([Kruglov Pavel](https://github.com/Avogar)).
* Fix no progress indication on INSERT FROM INFILE. Closes [#42548](https://github.com/ClickHouse/ClickHouse/issues/42548). [#42634](https://github.com/ClickHouse/ClickHouse/pull/42634) ([chen](https://github.com/xiedeyantu)).
* Refactor function `tokens` to enable max tokens returned for related functions (disabled by default). [#42673](https://github.com/ClickHouse/ClickHouse/pull/42673) ([李扬](https://github.com/taiyang-li)).
* Allow to use `Date32` arguments for `formatDateTime` and `FROM_UNIXTIME` functions. [#42737](https://github.com/ClickHouse/ClickHouse/pull/42737) ([Roman Vasin](https://github.com/rvasin)).
* Update tzdata to 2022f. Mexico will no longer observe DST except near the US border: https://www.timeanddate.com/news/time/mexico-abolishes-dst-2022.html. Chihuahua moves to year-round UTC-6 on 2022-10-30. Fiji no longer observes DST. See https://github.com/google/cctz/pull/235 and https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/1995209. [#42796](https://github.com/ClickHouse/ClickHouse/pull/42796) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add `FailedAsyncInsertQuery` event metric for async inserts. [#42814](https://github.com/ClickHouse/ClickHouse/pull/42814) ([Krzysztof Góralski](https://github.com/kgoralski)).
* Implement `read-in-order` optimization on top of query plan. It is enabled by default. Set `query_plan_read_in_order = 0` to use previous AST-based version. [#42829](https://github.com/ClickHouse/ClickHouse/pull/42829) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Increase the size of upload part exponentially for backup to S3 to avoid errors about max 10 000 parts limit of the multipart upload to s3. [#42833](https://github.com/ClickHouse/ClickHouse/pull/42833) ([Vitaly Baranov](https://github.com/vitlibar)).
* When the merge task is continuously busy and the disk space is insufficient, the completely expired parts cannot be selected and dropped, resulting in insufficient disk space. My idea is that when the entire Part expires, there is no need for additional disk space to guarantee, ensure the normal execution of TTL. [#42869](https://github.com/ClickHouse/ClickHouse/pull/42869) ([zhongyuankai](https://github.com/zhongyuankai)).
* Add `oss` function and `OSS` table engine (this is convenient for users). oss is fully compatible with s3. [#43155](https://github.com/ClickHouse/ClickHouse/pull/43155) ([zzsmdfj](https://github.com/zzsmdfj)).
* Improve error reporting in the collection of OS-related info for the `system.asynchronous_metrics` table. [#43192](https://github.com/ClickHouse/ClickHouse/pull/43192) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Modify the `INFORMATION_SCHEMA` tables in a way so that ClickHouse can connect to itself using the MySQL compatibility protocol. Add columns instead of aliases (related to [#9769](https://github.com/ClickHouse/ClickHouse/issues/9769)). It will improve the compatibility with various MySQL clients. [#43198](https://github.com/ClickHouse/ClickHouse/pull/43198) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
* Add some functions for compatibility with PowerBI, when it connects using MySQL protocol [#42612](https://github.com/ClickHouse/ClickHouse/pull/42612) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
* Better usability for Dashboard on changes [#42872](https://github.com/ClickHouse/ClickHouse/pull/42872) ([Vladimir C](https://github.com/vdimir)).

* Before the fix, the user-defined config was preserved by RPM in `$file.rpmsave`. The PR fixes it and won't replace the user's files from packages. [#42936](https://github.com/ClickHouse/ClickHouse/pull/42936) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Remove some libraries from Ubuntu Docker image. [#42622](https://github.com/ClickHouse/ClickHouse/pull/42622) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
#### Bug Fix (user-visible misbehavior in official stable or prestable release)
* Updated normaliser to clone the alias ast. Resolves [#42452](https://github.com/ClickHouse/ClickHouse/issues/42452) Implementation: * Updated QueryNormalizer to clone alias ast, when its replaced. Previously just assigning the same leads to exception in LogicalExpressinsOptimizer as it would be the same parent being inserted again. * This bug is not seen with new analyser (allow_experimental_analyzer), so no changes for it. I added a test for the same. [#42827](https://github.com/ClickHouse/ClickHouse/pull/42827) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).

* A null pointer will be generated when select if as from ‘three table join’ , For example, this SQL query: [#42883](https://github.com/ClickHouse/ClickHouse/pull/42883) ([zzsmdfj](https://github.com/zzsmdfj)).
* Fix memory sanitizer report in Cluster Discovery, close [#42763](https://github.com/ClickHouse/ClickHouse/issues/42763). [#42905](https://github.com/ClickHouse/ClickHouse/pull/42905) ([Vladimir C](https://github.com/vdimir)).
* Improve DateTime schema inference in case of empty string. [#42911](https://github.com/ClickHouse/ClickHouse/pull/42911) ([Kruglov Pavel](https://github.com/Avogar)).
* Fix rare NOT_FOUND_COLUMN_IN_BLOCK error when projection is possible to use but there is no projection available. This fixes [#42771](https://github.com/ClickHouse/ClickHouse/issues/42771) . The bug was introduced in https://github.com/ClickHouse/ClickHouse/pull/25563. [#42938](https://github.com/ClickHouse/ClickHouse/pull/42938) ([Amos Bird](https://github.com/amosbird)).
* Fix ATTACH TABLE in `PostgreSQL` database engine if the table contains DATETIME data type. Closes [#42817](https://github.com/ClickHouse/ClickHouse/issues/42817). [#42960](https://github.com/ClickHouse/ClickHouse/pull/42960) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fix lambda parsing. Closes [#41848](https://github.com/ClickHouse/ClickHouse/issues/41848). [#42979](https://github.com/ClickHouse/ClickHouse/pull/42979) ([Nikolay Degterinsky](https://github.com/evillique)).
* Fix incorrect key analysis when nullable keys appear in the middle of a hyperrectangle. This fixes [#43111](https://github.com/ClickHouse/ClickHouse/issues/43111) . [#43133](https://github.com/ClickHouse/ClickHouse/pull/43133) ([Amos Bird](https://github.com/amosbird)).

### <a id="2210"></a> ClickHouse release 22.10, 2022-10-26
#### Backward Incompatible Change
* Rename cache commands: `show caches` -> `show filesystem caches`, `describe cache` -> `describe filesystem cache`. [#41508](https://github.com/ClickHouse/ClickHouse/pull/41508) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Remove support for the `WITH TIMEOUT` section for `LIVE VIEW`. This closes [#40557](https://github.com/ClickHouse/ClickHouse/issues/40557). [#42173](https://github.com/ClickHouse/ClickHouse/pull/42173) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Remove support for the `{database}` macro from the client's prompt. It was displayed incorrectly if the database was unspecified and it was not updated on `USE` statements. This closes [#25891](https://github.com/ClickHouse/ClickHouse/issues/25891). [#42508](https://github.com/ClickHouse/ClickHouse/pull/42508) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
#### New Feature
* Composable protocol configuration is added. Now different protocols can be set up with different listen hosts. Protocol wrappers such as PROXYv1 can be set up over any other protocols (TCP, TCP secure, MySQL, Postgres). [#41198](https://github.com/ClickHouse/ClickHouse/pull/41198) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Add `S3` as a new type of the destination of backups. Support BACKUP to S3 with as-is path/data structure. [#42333](https://github.com/ClickHouse/ClickHouse/pull/42333) ([Vitaly Baranov](https://github.com/vitlibar)), [#42232](https://github.com/ClickHouse/ClickHouse/pull/42232) ([Azat Khuzhin](https://github.com/azat)).
* Added functions (`randUniform`, `randNormal`, `randLogNormal`, `randExponential`, `randChiSquared`, `randStudentT`, `randFisherF`, `randBernoulli`, `randBinomial`, `randNegativeBinomial`, `randPoisson`) to generate random values according to the specified distributions. This closes [#21834](https://github.com/ClickHouse/ClickHouse/issues/21834). [#42411](https://github.com/ClickHouse/ClickHouse/pull/42411) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* An improvement for ClickHouse Keeper: add support for uploading snapshots to S3. S3 information can be defined inside `keeper_server.s3_snapshot`. [#41342](https://github.com/ClickHouse/ClickHouse/pull/41342) ([Antonio Andelic](https://github.com/antonio2368)).
* Added an aggregate function `analysisOfVariance` (`anova`) to perform a statistical test over several groups of normally distributed observations to find out whether all groups have the same mean or not. Original PR [#37872](https://github.com/ClickHouse/ClickHouse/issues/37872). [#42131](https://github.com/ClickHouse/ClickHouse/pull/42131) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Support limiting of temporary data stored on disk using settings `max_temporary_data_on_disk_size_for_user`/`max_temporary_data_on_disk_size_for_query` . [#40893](https://github.com/ClickHouse/ClickHouse/pull/40893) ([Vladimir C](https://github.com/vdimir)).
* Add setting `format_json_object_each_row_column_for_object_name` to write/parse object name as column value in JSONObjectEachRow format. [#41703](https://github.com/ClickHouse/ClickHouse/pull/41703) ([Kruglov Pavel](https://github.com/Avogar)).
* Add BLAKE3 hash-function to SQL. [#33435](https://github.com/ClickHouse/ClickHouse/pull/33435) ([BoloniniD](https://github.com/BoloniniD)).
* The function `javaHash` has been extended to integers. [#41131](https://github.com/ClickHouse/ClickHouse/pull/41131) ([JackyWoo](https://github.com/JackyWoo)).
* Add OpenTelemetry support to ON CLUSTER DDL (require `distributed_ddl_entry_format_version` to be set to 4). [#41484](https://github.com/ClickHouse/ClickHouse/pull/41484) ([Frank Chen](https://github.com/FrankChen021)).
* Added system table `asynchronous_insert_log`. It contains information about asynchronous inserts (including results of queries in fire-and-forget mode (with `wait_for_async_insert=0`)) for better introspection. [#42040](https://github.com/ClickHouse/ClickHouse/pull/42040) ([Anton Popov](https://github.com/CurtizJ)).
* Add support for methods `lz4`, `bz2`, `snappy` in HTTP's `Accept-Encoding` which is a non-standard extension to HTTP protocol. [#42071](https://github.com/ClickHouse/ClickHouse/pull/42071) ([Nikolay Degterinsky](https://github.com/evillique)).
* Adds Morton Coding (ZCurve) encode/decode functions. [#41753](https://github.com/ClickHouse/ClickHouse/pull/41753) ([Constantine Peresypkin](https://github.com/pkit)).
* Add support for `SET setting_name = DEFAULT`. [#42187](https://github.com/ClickHouse/ClickHouse/pull/42187) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
#### Experimental Feature
* Added new infrastructure for query analysis and planning under the `allow_experimental_analyzer` setting. [#31796](https://github.com/ClickHouse/ClickHouse/pull/31796) ([Maksim Kita](https://github.com/kitaisreal)).
* Initial implementation of Kusto Query Language. Please don't use it. [#37961](https://github.com/ClickHouse/ClickHouse/pull/37961) ([Yong Wang](https://github.com/kashwy)).
#### Performance Improvement
* Relax the "Too many parts" threshold. This closes [#6551](https://github.com/ClickHouse/ClickHouse/issues/6551). Now ClickHouse will allow more parts in a partition if the average part size is large enough (at least 10 GiB). This allows to have up to petabytes of data in a single partition of a single table on a single server, which is possible using disk shelves or object storage. [#42002](https://github.com/ClickHouse/ClickHouse/pull/42002) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Implement operator precedence element parser to make the required stack size smaller. [#34892](https://github.com/ClickHouse/ClickHouse/pull/34892) ([Nikolay Degterinsky](https://github.com/evillique)).
* DISTINCT in order optimization leverage sorting properties of data streams. This improvement will enable reading in order for DISTINCT if applicable (before it was necessary to provide ORDER BY for columns in DISTINCT). [#41014](https://github.com/ClickHouse/ClickHouse/pull/41014) ([Igor Nikonov](https://github.com/devcrafter)).
* ColumnVector: optimize UInt8 index with AVX512VBMI. [#41247](https://github.com/ClickHouse/ClickHouse/pull/41247) ([Guo Wangyang](https://github.com/guowangy)).
* Optimize the lock contentions for `ThreadGroupStatus::mutex`. The performance experiments of **SSB** (Star Schema Benchmark) on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) shows that this change could bring a **2.95x** improvement of the geomean of all subcases' QPS. [#41675](https://github.com/ClickHouse/ClickHouse/pull/41675) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
* Add `ldapr` capabilities to AArch64 builds. This is supported from Graviton 2+, Azure and GCP instances. Only appeared in clang-15 [not so long ago](https://github.com/llvm/llvm-project/commit/9609b5daffe9fd28d83d83da895abc5113f76c24). [#41778](https://github.com/ClickHouse/ClickHouse/pull/41778) ([Daniel Kutenin](https://github.com/danlark1)).
* Improve performance when comparing strings and one argument is an empty constant string. [#41870](https://github.com/ClickHouse/ClickHouse/pull/41870) ([Jiebin Sun](https://github.com/jiebinn)).
* Optimize `insertFrom` of ColumnAggregateFunction to share Aggregate State in some cases. [#41960](https://github.com/ClickHouse/ClickHouse/pull/41960) ([flynn](https://github.com/ucasfl)).
* Make writing to `azure_blob_storage` disks faster (respect `max_single_part_upload_size` instead of writing a block per each buffer size). Inefficiency mentioned in [#41754](https://github.com/ClickHouse/ClickHouse/issues/41754). [#42041](https://github.com/ClickHouse/ClickHouse/pull/42041) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Make thread ids in the process list and query_log unique to avoid waste. [#42180](https://github.com/ClickHouse/ClickHouse/pull/42180) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Support skipping cache completely (both download to cache and reading cached data) in case the requested read range exceeds the threshold defined by cache setting `bypass_cache_threashold`, requires to be enabled with `enable_bypass_cache_with_threshold`). [#42418](https://github.com/ClickHouse/ClickHouse/pull/42418) ([Han Shukai](https://github.com/KinderRiven)). This helps on slow local disks.
#### Improvement
* Add setting `allow_implicit_no_password`: in combination with `allow_no_password` it forbids creating a user with no password unless `IDENTIFIED WITH no_password` is explicitly specified. [#41341](https://github.com/ClickHouse/ClickHouse/pull/41341) ([Nikolay Degterinsky](https://github.com/evillique)).
* Embedded Keeper will always start in the background allowing ClickHouse to start without achieving quorum. [#40991](https://github.com/ClickHouse/ClickHouse/pull/40991) ([Antonio Andelic](https://github.com/antonio2368)).
* Made reestablishing a new connection to ZooKeeper more reactive in case of expiration of the previous one. Previously there was a task which spawns every minute by default and thus a table could be in readonly state for about this time. [#41092](https://github.com/ClickHouse/ClickHouse/pull/41092) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Now projections can be used with zero copy replication (zero-copy replication is a non-production feature). [#41147](https://github.com/ClickHouse/ClickHouse/pull/41147) ([alesapin](https://github.com/alesapin)).
* Support expression `(EXPLAIN SELECT ...)` in a subquery. Queries like `SELECT * FROM (EXPLAIN PIPELINE SELECT col FROM TABLE ORDER BY col)` became valid. [#40630](https://github.com/ClickHouse/ClickHouse/pull/40630) ([Vladimir C](https://github.com/vdimir)).
* Allow changing `async_insert_max_data_size` or `async_insert_busy_timeout_ms` in scope of query. E.g. user wants to insert data rarely and she doesn't have access to the server config to tune default settings. [#40668](https://github.com/ClickHouse/ClickHouse/pull/40668) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Improvements for reading from remote filesystems, made threadpool size for reads/writes configurable. Closes [#41070](https://github.com/ClickHouse/ClickHouse/issues/41070). [#41011](https://github.com/ClickHouse/ClickHouse/pull/41011) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Support all combinators combination in WindowTransform/arratReduce*/initializeAggregation/aggregate functions versioning. Previously combinators like `ForEach/Resample/Map` didn't work in these places, using them led to exception like`State function ... inserts results into non-state column`. [#41107](https://github.com/ClickHouse/ClickHouse/pull/41107) ([Kruglov Pavel](https://github.com/Avogar)).
* Add function `tryDecrypt` that returns NULL when decrypt fails (e.g. decrypt with incorrect key) instead of throwing an exception. [#41206](https://github.com/ClickHouse/ClickHouse/pull/41206) ([Duc Canh Le](https://github.com/canhld94)).
* Add the `unreserved_space` column to the `system.disks` table to check how much space is not taken by reservations per disk. [#41254](https://github.com/ClickHouse/ClickHouse/pull/41254) ([filimonov](https://github.com/filimonov)).
* Support s3 authorization headers in table function arguments. [#41261](https://github.com/ClickHouse/ClickHouse/pull/41261) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Add support for MultiRead in Keeper and internal ZooKeeper client (this is an extension to ZooKeeper protocol, only available in ClickHouse Keeper). [#41410](https://github.com/ClickHouse/ClickHouse/pull/41410) ([Antonio Andelic](https://github.com/antonio2368)).
* Add support for decimal type comparing with floating point literal in IN operator. [#41544](https://github.com/ClickHouse/ClickHouse/pull/41544) ([liang.huang](https://github.com/lhuang09287750)).
* Allow readable size values (like `1TB`) in cache config. [#41688](https://github.com/ClickHouse/ClickHouse/pull/41688) ([Kseniia Sumarokova](https://github.com/kssenii)).
* ClickHouse could cache stale DNS entries for some period of time (15 seconds by default) until the cache won't be updated asynchronously. During these periods ClickHouse can nevertheless try to establish a connection and produce errors. This behavior is fixed. [#41707](https://github.com/ClickHouse/ClickHouse/pull/41707) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Add interactive history search with fzf-like utility (fzf/sk) for `clickhouse-client`/`clickhouse-local` (note you can use `FZF_DEFAULT_OPTS`/`SKIM_DEFAULT_OPTIONS` to additionally configure the behavior). [#41730](https://github.com/ClickHouse/ClickHouse/pull/41730) ([Azat Khuzhin](https://github.com/azat)).
* Only allow clients connecting to a secure server with an invalid certificate only to proceed with the '--accept-certificate' flag. [#41743](https://github.com/ClickHouse/ClickHouse/pull/41743) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Add function `tryBase58Decode`, similar to the existing function `tryBase64Decode`. [#41824](https://github.com/ClickHouse/ClickHouse/pull/41824) ([Robert Schulze](https://github.com/rschu1ze)).
* Improve feedback when replacing partition with different primary key. Fixes [#34798](https://github.com/ClickHouse/ClickHouse/issues/34798). [#41838](https://github.com/ClickHouse/ClickHouse/pull/41838) ([Salvatore](https://github.com/tbsal)).
* Fix parallel parsing: segmentator now checks `max_block_size`. This fixed memory overallocation in case of parallel parsing and small LIMIT. [#41852](https://github.com/ClickHouse/ClickHouse/pull/41852) ([Vitaly Baranov](https://github.com/vitlibar)).
* Don't add "TABLE_IS_DROPPED" exception to `system.errors` if it's happened during SELECT from a system table and was ignored. [#41908](https://github.com/ClickHouse/ClickHouse/pull/41908) ([AlfVII](https://github.com/AlfVII)).
* Improve option `enable_extended_results_for_datetime_functions` to return results of type DateTime64 for functions `toStartOfDay`, `toStartOfHour`, `toStartOfFifteenMinutes`, `toStartOfTenMinutes`, `toStartOfFiveMinutes`, `toStartOfMinute` and `timeSlot`. [#41910](https://github.com/ClickHouse/ClickHouse/pull/41910) ([Roman Vasin](https://github.com/rvasin)).
* Improve `DateTime` type inference for text formats. Now it respects setting `date_time_input_format` and doesn't try to infer datetimes from numbers as timestamps. Closes [#41389](https://github.com/ClickHouse/ClickHouse/issues/41389) Closes [#42206](https://github.com/ClickHouse/ClickHouse/issues/42206). [#41912](https://github.com/ClickHouse/ClickHouse/pull/41912) ([Kruglov Pavel](https://github.com/Avogar)).
* Remove confusing warning when inserting with `perform_ttl_move_on_insert` = false. [#41980](https://github.com/ClickHouse/ClickHouse/pull/41980) ([Vitaly Baranov](https://github.com/vitlibar)).
* Allow user to write `countState(*)` similar to `count(*)`. This closes [#9338](https://github.com/ClickHouse/ClickHouse/issues/9338). [#41983](https://github.com/ClickHouse/ClickHouse/pull/41983) ([Amos Bird](https://github.com/amosbird)).
* Fix `rankCorr` size overflow. [#42020](https://github.com/ClickHouse/ClickHouse/pull/42020) ([Duc Canh Le](https://github.com/canhld94)).
* Added an option to specify an arbitrary string as an environment name in the Sentry's config for more handy reports. [#42037](https://github.com/ClickHouse/ClickHouse/pull/42037) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Fix parsing out-of-range Date from CSV. [#42044](https://github.com/ClickHouse/ClickHouse/pull/42044) ([Andrey Zvonov](https://github.com/zvonand)).
* `parseDataTimeBestEffort` now supports comma between date and time. Closes [#42038](https://github.com/ClickHouse/ClickHouse/issues/42038). [#42049](https://github.com/ClickHouse/ClickHouse/pull/42049) ([flynn](https://github.com/ucasfl)).
* Improved stale replica recovery process for `ReplicatedMergeTree`. If a lost replica has some parts which are absent from a healthy replica, but these parts should appear in the future according to the replication queue of the healthy replica, then the lost replica will keep such parts instead of detaching them. [#42134](https://github.com/ClickHouse/ClickHouse/pull/42134) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Add a possibility to use `Date32` arguments for date_diff function. Fix issue in date_diff function when using DateTime64 arguments with a start date before Unix epoch and end date after Unix epoch. [#42308](https://github.com/ClickHouse/ClickHouse/pull/42308) ([Roman Vasin](https://github.com/rvasin)).
* When uploading big parts to Minio, 'Complete Multipart Upload' can take a long time. Minio sends heartbeats every 10 seconds (see https://github.com/minio/minio/pull/7198). But clickhouse times out earlier, because the default send/receive timeout is [set](https://github.com/ClickHouse/ClickHouse/blob/cc24fcd6d5dfb67f5f66f5483e986bd1010ad9cf/src/IO/S3/PocoHTTPClient.cpp#L123) to 5 seconds. [#42321](https://github.com/ClickHouse/ClickHouse/pull/42321) ([filimonov](https://github.com/filimonov)).
* Fix rarely invalid cast of aggregate state types with complex types such as Decimal. This fixes [#42408](https://github.com/ClickHouse/ClickHouse/issues/42408). [#42417](https://github.com/ClickHouse/ClickHouse/pull/42417) ([Amos Bird](https://github.com/amosbird)).
* Allow to use `Date32` arguments for `dateName` function. [#42554](https://github.com/ClickHouse/ClickHouse/pull/42554) ([Roman Vasin](https://github.com/rvasin)).
* Now filters with NULL literals will be used during index analysis. [#34063](https://github.com/ClickHouse/ClickHouse/issues/34063). [#41842](https://github.com/ClickHouse/ClickHouse/pull/41842) ([Amos Bird](https://github.com/amosbird)).
* Merge parts if every part in the range is older than a certain threshold. The threshold can be set by using `min_age_to_force_merge_seconds`. This closes [#35836](https://github.com/ClickHouse/ClickHouse/issues/35836). [#42423](https://github.com/ClickHouse/ClickHouse/pull/42423) ([Antonio Andelic](https://github.com/antonio2368)). This is continuation of [#39550i](https://github.com/ClickHouse/ClickHouse/pull/39550) by [@fastio](https://github.com/fastio) who implemented most of the logic.
* Improve the time to recover lost keeper connections. [#42541](https://github.com/ClickHouse/ClickHouse/pull/42541) ([Raúl Marín](https://github.com/Algunenano)).
#### Build/Testing/Packaging Improvement
* Add fuzzer for table definitions [#40096](https://github.com/ClickHouse/ClickHouse/pull/40096) ([Anton Popov](https://github.com/CurtizJ)). This represents the biggest advancement for ClickHouse testing in this year so far.
* Beta version of the ClickHouse Cloud service is released: [https://clickhouse.cloud/](https://clickhouse.cloud/). It provides the easiest way to use ClickHouse (even slightly easier than the single-command installation).

* Aarch64 binaries now require at least ARMv8.2, released in 2016. Most notably, this enables use of ARM LSE, i.e. native atomic operations. Also, CMake build option "NO_ARMV81_OR_HIGHER" has been added to allow compilation of binaries for older ARMv8.0 hardware, e.g. Raspberry Pi 4. [#41610](https://github.com/ClickHouse/ClickHouse/pull/41610) ([Robert Schulze](https://github.com/rschu1ze)).
* Allow building ClickHouse with Musl (small changes after it was already supported but broken). [#41987](https://github.com/ClickHouse/ClickHouse/pull/41987) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add the `$CLICKHOUSE_CRONFILE` file checking to avoid running the `sed` command to get the file not found error on install. [#42081](https://github.com/ClickHouse/ClickHouse/pull/42081) ([Chun-Sheng, Li](https://github.com/peter279k)).
* Update cctz to `2022e` to support the new timezone changes. Palestine transitions are now Saturdays at 02:00. Simplify three Ukraine zones into one. Jordan and Syria switch from +02/+03 with DST to year-round +03. (https://data.iana.org/time-zones/tzdb/NEWS). This closes [#42252](https://github.com/ClickHouse/ClickHouse/issues/42252). [#42327](https://github.com/ClickHouse/ClickHouse/pull/42327) ([Alexey Milovidov](https://github.com/alexey-milovidov)). [#42273](https://github.com/ClickHouse/ClickHouse/pull/42273) ([Dom Del Nano](https://github.com/ddelnano)).

* Fix wrong result of queries with `ORDER BY` or `GROUP BY` by columns from prefix of sorting key, wrapped into monotonic functions, with enable "read in order" optimization (settings `optimize_read_in_order` and `optimize_aggregation_in_order`). [#41701](https://github.com/ClickHouse/ClickHouse/pull/41701) ([Anton Popov](https://github.com/CurtizJ)).
* Fix possible crash in `SELECT` from `Merge` table with enabled `optimize_monotonous_functions_in_order_by` setting. Fixes [#41269](https://github.com/ClickHouse/ClickHouse/issues/41269). [#41740](https://github.com/ClickHouse/ClickHouse/pull/41740) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Fixed "Part ... intersects part ..." error that might happen in extremely rare cases if replica was restarted just after detaching some part as broken. [#41741](https://github.com/ClickHouse/ClickHouse/pull/41741) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Don't allow to create or alter merge tree tables with column name `_row_exists`, which is reserved for lightweight delete. Fixed [#41716](https://github.com/ClickHouse/ClickHouse/issues/41716). [#41763](https://github.com/ClickHouse/ClickHouse/pull/41763) ([Jianmei Zhang](https://github.com/zhangjmruc)).

* 22.9 might fail to startup `ReplicatedMergeTree` table if that table was created by 20.3 or older version and was never altered, it's fixed. Fixes [#41742](https://github.com/ClickHouse/ClickHouse/issues/41742). [#41796](https://github.com/ClickHouse/ClickHouse/pull/41796) ([Alexander Tokmakov](https://github.com/tavplubix)).
* When the batch sending fails for some reason, it cannot be automatically recovered, and if it is not processed in time, it will lead to accumulation, and the printed error message will become longer and longer, which will cause the http thread to block. [#41813](https://github.com/ClickHouse/ClickHouse/pull/41813) ([zhongyuankai](https://github.com/zhongyuankai)).
* Fix compact parts with compressed marks setting. Fixes [#41783](https://github.com/ClickHouse/ClickHouse/issues/41783) and [#41746](https://github.com/ClickHouse/ClickHouse/issues/41746). [#41823](https://github.com/ClickHouse/ClickHouse/pull/41823) ([alesapin](https://github.com/alesapin)).
* Old versions of Replicated database don't have a special marker in [Zoo]Keeper. We need to check only whether the node contains come obscure data instead of special mark. [#41875](https://github.com/ClickHouse/ClickHouse/pull/41875) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Fix possible exception in fs cache. [#41884](https://github.com/ClickHouse/ClickHouse/pull/41884) ([Kseniia Sumarokova](https://github.com/kssenii)).

* `toDateTime64` now returns the same output with negative integer and float arguments. [#42025](https://github.com/ClickHouse/ClickHouse/pull/42025) ([Robert Schulze](https://github.com/rschu1ze)).
* Fix write into `azure_blob_storage`. Partially closes [#41754](https://github.com/ClickHouse/ClickHouse/issues/41754). [#42034](https://github.com/ClickHouse/ClickHouse/pull/42034) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fix the `bzip2` decoding issue for specific `bzip2` files. [#42046](https://github.com/ClickHouse/ClickHouse/pull/42046) ([Nikolay Degterinsky](https://github.com/evillique)).

[#42084](https://github.com/ClickHouse/ClickHouse/pull/42084) ([Roman Vasin](https://github.com/rvasin)).
* The maximum size of fetches for each table accidentally was set to 8 while the pool size could be bigger. Now the maximum size of fetches for table is equal to the pool size. [#42090](https://github.com/ClickHouse/ClickHouse/pull/42090) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* A table might be shut down and a dictionary might be detached before checking if can be dropped without breaking dependencies between table, it's fixed. Fixes [#41982](https://github.com/ClickHouse/ClickHouse/issues/41982). [#42106](https://github.com/ClickHouse/ClickHouse/pull/42106) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Fix bad inefficiency of `remote_filesystem_read_method=read` with filesystem cache. Closes [#42125](https://github.com/ClickHouse/ClickHouse/issues/42125). [#42129](https://github.com/ClickHouse/ClickHouse/pull/42129) ([Kseniia Sumarokova](https://github.com/kssenii)).

* Fix a bug with projections and the `aggregate_functions_null_for_empty` setting. This bug is very rare and appears only if you enable the `aggregate_functions_null_for_empty` setting in the server's config. This closes [#41647](https://github.com/ClickHouse/ClickHouse/issues/41647). [#42198](https://github.com/ClickHouse/ClickHouse/pull/42198) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

* `ALTER UPDATE` of attached part (with columns different from table schema) could create an invalid `columns.txt` metadata on disk. Reading from such part could fail with errors or return invalid data. Fixes [#42161](https://github.com/ClickHouse/ClickHouse/issues/42161). [#42319](https://github.com/ClickHouse/ClickHouse/pull/42319) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Setting `additional_table_filters` were not applied to `Distributed` storage. Fixes [#41692](https://github.com/ClickHouse/ClickHouse/issues/41692). [#42322](https://github.com/ClickHouse/ClickHouse/pull/42322) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Fix a data race in query finish/cancel. This closes [#42346](https://github.com/ClickHouse/ClickHouse/issues/42346). [#42362](https://github.com/ClickHouse/ClickHouse/pull/42362) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* This reverts [#40217](https://github.com/ClickHouse/ClickHouse/issues/40217) which introduced a regression in date/time functions. [#42367](https://github.com/ClickHouse/ClickHouse/pull/42367) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fix assert cast in join on falsy condition, Close [#42380](https://github.com/ClickHouse/ClickHouse/issues/42380). [#42407](https://github.com/ClickHouse/ClickHouse/pull/42407) ([Vladimir C](https://github.com/vdimir)).

* `AggregateFunctionQuantile` now correctly works with UInt128 columns. Previously, the quantile state interpreted `UInt128` columns as `Int128` which could have led to incorrect results. [#42473](https://github.com/ClickHouse/ClickHouse/pull/42473) ([Antonio Andelic](https://github.com/antonio2368)).
* Fix bad_cast assert during INSERT into `Annoy` indexes over non-Float32 columns. `Annoy` indices is an experimental feature. [#42485](https://github.com/ClickHouse/ClickHouse/pull/42485) ([Robert Schulze](https://github.com/rschu1ze)).
* Arithmetic operator with Date or DateTime and 128 or 256-bit integer was referencing uninitialized memory. [#42453](https://github.com/ClickHouse/ClickHouse/issues/42453). [#42573](https://github.com/ClickHouse/ClickHouse/pull/42573) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fix unexpected table loading error when partition key contains alias function names during server upgrade. [#36379](https://github.com/ClickHouse/ClickHouse/pull/36379) ([Amos Bird](https://github.com/amosbird)).
### <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)).

* 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.

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)).

### <a id="228"></a> ClickHouse release 22.8-lts, 2022-08-18
#### Backward Incompatible Change
* Extended range of `Date32` and `DateTime64` to support dates from the year 1900 to 2299. In previous versions, the supported interval was only from the year 1925 to 2283. The implementation is using the proleptic Gregorian calendar (which is conformant with [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601):2004 (clause 3.2.1 The Gregorian calendar)) instead of accounting for historical transitions from the Julian to the Gregorian calendar. This change affects implementation-specific behavior for out-of-range arguments. E.g. if in previous versions the value of `1899-01-01` was clamped to `1925-01-01`, in the new version it will be clamped to `1900-01-01`. It changes the behavior of rounding with `toStartOfInterval` if you pass `INTERVAL 3 QUARTER` up to one quarter because the intervals are counted from an implementation-specific point of time. Closes [#28216](https://github.com/ClickHouse/ClickHouse/issues/28216), improves [#38393](https://github.com/ClickHouse/ClickHouse/issues/38393). [#39425](https://github.com/ClickHouse/ClickHouse/pull/39425) ([Roman Vasin](https://github.com/rvasin)).
* Now, all relevant dictionary sources respect `remote_url_allow_hosts` setting. It was already done for HTTP, Cassandra, Redis. Added ClickHouse, MongoDB, MySQL, PostgreSQL. Host is checked only for dictionaries created from DDL. [#39184](https://github.com/ClickHouse/ClickHouse/pull/39184) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Make the remote filesystem cache composable, allow not to evict certain files (regarding idx, mrk, ..), delete old cache version. Now it is possible to configure cache over Azure blob storage disk, over Local disk, over StaticWeb disk, etc. This PR is marked backward incompatible because cache configuration changes and in order for cache to work need to update the config file. Old cache will still be used with new configuration. The server will startup fine with the old cache configuration. Closes https://github.com/ClickHouse/ClickHouse/issues/36140. Closes https://github.com/ClickHouse/ClickHouse/issues/37889. ([Kseniia Sumarokova](https://github.com/kssenii)). [#36171](https://github.com/ClickHouse/ClickHouse/pull/36171))
#### New Feature
* Query parameters can be set in interactive mode as `SET param_abc = 'def'` and transferred via the native protocol as settings. [#39906](https://github.com/ClickHouse/ClickHouse/pull/39906) ([Nikita Taranov](https://github.com/nickitat)).
* Quota key can be set in the native protocol ([Yakov Olkhovsky](https://github.com/ClickHouse/ClickHouse/pull/39874)).
* Added a setting `exact_rows_before_limit` (0/1). When enabled, ClickHouse will provide exact value for `rows_before_limit_at_least` statistic, but with the cost that the data before limit will have to be read completely. This closes [#6613](https://github.com/ClickHouse/ClickHouse/issues/6613). [#25333](https://github.com/ClickHouse/ClickHouse/pull/25333) ([kevin wan](https://github.com/MaxWk)).
* Added support for parallel distributed insert select with `s3Cluster` table function into tables with `Distributed` and `Replicated` engine [#34670](https://github.com/ClickHouse/ClickHouse/issues/34670). [#39107](https://github.com/ClickHouse/ClickHouse/pull/39107) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Add new settings to control schema inference from text formats: - `input_format_try_infer_dates` - try infer dates from strings. - `input_format_try_infer_datetimes` - try infer datetimes from strings. - `input_format_try_infer_integers` - try infer `Int64` instead of `Float64`. - `input_format_json_try_infer_numbers_from_strings` - try infer numbers from json strings in JSON formats. [#39186](https://github.com/ClickHouse/ClickHouse/pull/39186) ([Kruglov Pavel](https://github.com/Avogar)).
* An option to provide JSON formatted log output. The purpose is to allow easier ingestion and query in log analysis tools. [#39277](https://github.com/ClickHouse/ClickHouse/pull/39277) ([Mallik Hassan](https://github.com/SadiHassan)).
* Add function `nowInBlock` which allows getting the current time during long-running and continuous queries. Closes [#39522](https://github.com/ClickHouse/ClickHouse/issues/39522). Notes: there are no functions `now64InBlock` neither `todayInBlock`. [#39533](https://github.com/ClickHouse/ClickHouse/pull/39533) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add ability to specify settings for an `executable()` table function. [#39681](https://github.com/ClickHouse/ClickHouse/pull/39681) ([Constantine Peresypkin](https://github.com/pkit)).
* Implemented automatic conversion of database engine from `Ordinary` to `Atomic`. Create empty `convert_ordinary_to_atomic` file in `flags` directory and all `Ordinary` databases will be converted automatically on next server start. Resolves [#39546](https://github.com/ClickHouse/ClickHouse/issues/39546). [#39933](https://github.com/ClickHouse/ClickHouse/pull/39933) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Support `SELECT ... INTO OUTFILE '...' AND STDOUT`. [#37490](https://github.com/ClickHouse/ClickHouse/issues/37490). [#39054](https://github.com/ClickHouse/ClickHouse/pull/39054) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
* Add formats `PrettyMonoBlock`, `PrettyNoEscapesMonoBlock`, `PrettyCompactNoEscapes`, `PrettyCompactNoEscapesMonoBlock`, `PrettySpaceNoEscapes`, `PrettySpaceMonoBlock`, `PrettySpaceNoEscapesMonoBlock`. [#39646](https://github.com/ClickHouse/ClickHouse/pull/39646) ([Kruglov Pavel](https://github.com/Avogar)).
* Add new setting schema_inference_hints that allows to specify structure hints in schema inference for specific columns. Closes [#39569](https://github.com/ClickHouse/ClickHouse/issues/39569). [#40068](https://github.com/ClickHouse/ClickHouse/pull/40068) ([Kruglov Pavel](https://github.com/Avogar)).
#### Experimental Feature
* Support SQL standard DELETE FROM syntax on merge tree tables and lightweight delete implementation for merge tree families. [#37893](https://github.com/ClickHouse/ClickHouse/pull/37893) ([Jianmei Zhang](https://github.com/zhangjmruc)) ([Alexander Gololobov](https://github.com/davenger)). Note: this new feature does not make ClickHouse an HTAP DBMS.
#### Performance Improvement
* Improved memory usage during memory efficient merging of aggregation results. [#39429](https://github.com/ClickHouse/ClickHouse/pull/39429) ([Nikita Taranov](https://github.com/nickitat)).
* Added concurrency control logic to limit total number of concurrent threads created by queries. [#37558](https://github.com/ClickHouse/ClickHouse/pull/37558) ([Sergei Trifonov](https://github.com/serxa)). Add `concurrent_threads_soft_limit parameter` to increase performance in case of high QPS by means of limiting total number of threads for all queries. [#37285](https://github.com/ClickHouse/ClickHouse/pull/37285) ([Roman Vasin](https://github.com/rvasin)).
* Add `SLRU` cache policy for uncompressed cache and marks cache. ([Kseniia Sumarokova](https://github.com/kssenii)). [#34651](https://github.com/ClickHouse/ClickHouse/pull/34651) ([alexX512](https://github.com/alexX512)). Decoupling local cache function and cache algorithm [#38048](https://github.com/ClickHouse/ClickHouse/pull/38048) ([Han Shukai](https://github.com/KinderRiven)).
* Intel® In-Memory Analytics Accelerator (Intel® IAA) is a hardware accelerator available in the upcoming generation of Intel® Xeon® Scalable processors ("Sapphire Rapids"). Its goal is to speed up common operations in analytics like data (de)compression and filtering. ClickHouse gained the new "DeflateQpl" compression codec which utilizes the Intel® IAA offloading technology to provide a high-performance DEFLATE implementation. The codec uses the [Intel® Query Processing Library (QPL)](https://github.com/intel/qpl) which abstracts access to the hardware accelerator, respectively to a software fallback in case the hardware accelerator is not available. DEFLATE provides in general higher compression rates than ClickHouse's LZ4 default codec, and as a result, offers less disk I/O and lower main memory consumption. [#36654](https://github.com/ClickHouse/ClickHouse/pull/36654) ([jasperzhu](https://github.com/jinjunzh)). [#39494](https://github.com/ClickHouse/ClickHouse/pull/39494) ([Robert Schulze](https://github.com/rschu1ze)).
* `DISTINCT` in order with `ORDER BY`: Deduce way to sort based on input stream sort description. Skip sorting if input stream is already sorted. [#38719](https://github.com/ClickHouse/ClickHouse/pull/38719) ([Igor Nikonov](https://github.com/devcrafter)). Improve memory usage (significantly) and query execution time + use `DistinctSortedChunkTransform` for final distinct when `DISTINCT` columns match `ORDER BY` columns, but rename to `DistinctSortedStreamTransform` in `EXPLAIN PIPELINE` → this improves memory usage significantly + remove unnecessary allocations in hot loop in `DistinctSortedChunkTransform`. [#39432](https://github.com/ClickHouse/ClickHouse/pull/39432) ([Igor Nikonov](https://github.com/devcrafter)). Use `DistinctSortedTransform` only when sort description is applicable to DISTINCT columns, otherwise fall back to ordinary DISTINCT implementation + it allows making less checks during `DistinctSortedTransform` execution. [#39528](https://github.com/ClickHouse/ClickHouse/pull/39528) ([Igor Nikonov](https://github.com/devcrafter)). Fix: `DistinctSortedTransform` didn't take advantage of sorting. It never cleared HashSet since clearing_columns were detected incorrectly (always empty). So, it basically worked as ordinary `DISTINCT` (`DistinctTransform`). The fix reduces memory usage significantly. [#39538](https://github.com/ClickHouse/ClickHouse/pull/39538) ([Igor Nikonov](https://github.com/devcrafter)).
* Use local node as first priority to get structure of remote table when executing `cluster` and similar table functions. [#39440](https://github.com/ClickHouse/ClickHouse/pull/39440) ([Mingliang Pan](https://github.com/liangliangpan)).
* Optimize filtering by numeric columns with AVX512VBMI2 compress store. [#39633](https://github.com/ClickHouse/ClickHouse/pull/39633) ([Guo Wangyang](https://github.com/guowangy)). For systems with AVX512 VBMI2, this PR improves performance by ca. 6% for SSB benchmark queries queries 3.1, 3.2 and 3.3 (SF=100). Tested on Intel Icelake Xeon 8380 * 2 socket. [#40033](https://github.com/ClickHouse/ClickHouse/pull/40033) ([Robert Schulze](https://github.com/rschu1ze)).
* Optimize index analysis with functional expressions in multi-thread scenario. [#39812](https://github.com/ClickHouse/ClickHouse/pull/39812) ([Guo Wangyang](https://github.com/guowangy)).
* Optimizations for complex queries: Don't visit the AST for UDFs if none are registered. [#40069](https://github.com/ClickHouse/ClickHouse/pull/40069) ([Raúl Marín](https://github.com/Algunenano)). Optimize CurrentMemoryTracker alloc and free. [#40078](https://github.com/ClickHouse/ClickHouse/pull/40078) ([Raúl Marín](https://github.com/Algunenano)).
* Improved Base58 encoding/decoding. [#39292](https://github.com/ClickHouse/ClickHouse/pull/39292) ([Andrey Zvonov](https://github.com/zvonand)).
* Improve bytes to bits mask transform for SSE/AVX/AVX512. [#39586](https://github.com/ClickHouse/ClickHouse/pull/39586) ([Guo Wangyang](https://github.com/guowangy)).
#### Improvement
* Normalize `AggregateFunction` types and state representations because optimizations like [#35788](https://github.com/ClickHouse/ClickHouse/pull/35788) will treat `count(not null columns)` as `count()`, which might confuses distributed interpreters with the following error : `Conversion from AggregateFunction(count) to AggregateFunction(count, Int64) is not supported`. [#39420](https://github.com/ClickHouse/ClickHouse/pull/39420) ([Amos Bird](https://github.com/amosbird)). The functions with identical states can be used in materialized views interchangeably.
* Rework and simplify the `system.backups` table, remove the `internal` column, allow user to set the ID of operation, add columns `num_files`, `uncompressed_size`, `compressed_size`, `start_time`, `end_time`. [#39503](https://github.com/ClickHouse/ClickHouse/pull/39503) ([Vitaly Baranov](https://github.com/vitlibar)).
* Improved structure of DDL query result table for `Replicated` database (separate columns with shard and replica name, more clear status) - `CREATE TABLE ... ON CLUSTER` queries can be normalized on initiator first if `distributed_ddl_entry_format_version` is set to 3 (default value). It means that `ON CLUSTER` queries may not work if initiator does not belong to the cluster that specified in query. Fixes [#37318](https://github.com/ClickHouse/ClickHouse/issues/37318), [#39500](https://github.com/ClickHouse/ClickHouse/issues/39500) - Ignore `ON CLUSTER` clause if database is `Replicated` and cluster name equals to database name. Related to [#35570](https://github.com/ClickHouse/ClickHouse/issues/35570) - Miscellaneous minor fixes for `Replicated` database engine - Check metadata consistency when starting up `Replicated` database, start replica recovery in case of mismatch of local metadata and metadata in Keeper. Resolves [#24880](https://github.com/ClickHouse/ClickHouse/issues/24880). [#37198](https://github.com/ClickHouse/ClickHouse/pull/37198) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Add result_rows and result_bytes to progress reports (`X-ClickHouse-Summary`). [#39567](https://github.com/ClickHouse/ClickHouse/pull/39567) ([Raúl Marín](https://github.com/Algunenano)).
* Improve primary key analysis for MergeTree. [#25563](https://github.com/ClickHouse/ClickHouse/pull/25563) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* `timeSlots` now works with DateTime64; subsecond duration and slot size available when working with DateTime64. [#37951](https://github.com/ClickHouse/ClickHouse/pull/37951) ([Andrey Zvonov](https://github.com/zvonand)).
* Added support of `LEFT SEMI` and `LEFT ANTI` direct join with `EmbeddedRocksDB` tables. [#38956](https://github.com/ClickHouse/ClickHouse/pull/38956) ([Vladimir C](https://github.com/vdimir)).
* Add profile events for fsync operations. [#39179](https://github.com/ClickHouse/ClickHouse/pull/39179) ([Azat Khuzhin](https://github.com/azat)).
* Add the second argument to the ordinary function `file(path[, default])`, which function returns in the case when a file does not exists. [#39218](https://github.com/ClickHouse/ClickHouse/pull/39218) ([Nikolay Degterinsky](https://github.com/evillique)).
* Some small fixes for reading via http, allow to retry partial content in case if 200 OK. [#39244](https://github.com/ClickHouse/ClickHouse/pull/39244) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Support queries `CREATE TEMPORARY TABLE ... (<list of columns>) AS ...`. [#39462](https://github.com/ClickHouse/ClickHouse/pull/39462) ([Kruglov Pavel](https://github.com/Avogar)).
* Add support of `!`/`*` (exclamation/asterisk) in custom TLDs (`cutToFirstSignificantSubdomainCustom()`/`cutToFirstSignificantSubdomainCustomWithWWW()`/`firstSignificantSubdomainCustom()`). [#39496](https://github.com/ClickHouse/ClickHouse/pull/39496) ([Azat Khuzhin](https://github.com/azat)).
* Add support for TLS connections to NATS. Implements [#39525](https://github.com/ClickHouse/ClickHouse/issues/39525). [#39527](https://github.com/ClickHouse/ClickHouse/pull/39527) ([Constantine Peresypkin](https://github.com/pkit)).
* `clickhouse-obfuscator` (a tool for database obfuscation for testing and load generation) now has the new `--save` and `--load` parameters to work with pre-trained models. This closes [#39534](https://github.com/ClickHouse/ClickHouse/issues/39534). [#39541](https://github.com/ClickHouse/ClickHouse/pull/39541) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fix incorrect behavior of log rotation during restart. [#39558](https://github.com/ClickHouse/ClickHouse/pull/39558) ([Nikolay Degterinsky](https://github.com/evillique)).
* Fix building aggregate projections when external aggregation is on. Mark as improvement because the case is rare and there exists easy workaround to fix it via changing settings. This fixes [#39667](https://github.com/ClickHouse/ClickHouse/issues/39667) . [#39671](https://github.com/ClickHouse/ClickHouse/pull/39671) ([Amos Bird](https://github.com/amosbird)).
* Allow to execute hash functions with arguments of type `Map`. [#39685](https://github.com/ClickHouse/ClickHouse/pull/39685) ([Anton Popov](https://github.com/CurtizJ)).
* Add a configuration parameter to hide addresses in stack traces. It may improve security a little but generally, it is harmful and should not be used. [#39690](https://github.com/ClickHouse/ClickHouse/pull/39690) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Change the prefix size of AggregateFunctionDistinct to make sure nested function data memory segment is aligned. [#39696](https://github.com/ClickHouse/ClickHouse/pull/39696) ([Pxl](https://github.com/BiteTheDDDDt)).
* Properly escape credentials passed to the `clickhouse-diagnostic` tool. [#39707](https://github.com/ClickHouse/ClickHouse/pull/39707) ([Dale McDiarmid](https://github.com/gingerwizard)).
* ClickHouse Keeper improvement: create a snapshot on exit. It can be controlled with the config `keeper_server.create_snapshot_on_exit`, `true` by default. [#39755](https://github.com/ClickHouse/ClickHouse/pull/39755) ([Antonio Andelic](https://github.com/antonio2368)).
* Support primary key analysis for `row_policy_filter` and `additional_filter`. It also helps fix issues like [#37454](https://github.com/ClickHouse/ClickHouse/issues/37454) . [#39826](https://github.com/ClickHouse/ClickHouse/pull/39826) ([Amos Bird](https://github.com/amosbird)).
* Fix two usability issues in Play UI: - it was non-pixel-perfect on iPad due to parasitic border radius and margins; - the progress indication did not display after the first query. This closes [#39957](https://github.com/ClickHouse/ClickHouse/issues/39957). This closes [#39960](https://github.com/ClickHouse/ClickHouse/issues/39960). [#39961](https://github.com/ClickHouse/ClickHouse/pull/39961) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Play UI: add row numbers; add cell selection on click; add hysteresis for table cells. [#39962](https://github.com/ClickHouse/ClickHouse/pull/39962) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Play UI: recognize tab key in textarea, but at the same time don't mess up with tab navigation. [#40053](https://github.com/ClickHouse/ClickHouse/pull/40053) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* The client will show server-side elapsed time. This is important for the performance comparison of ClickHouse services in remote datacenters. This closes [#38070](https://github.com/ClickHouse/ClickHouse/issues/38070). See also [this](https://github.com/ClickHouse/ClickBench/blob/main/hardware/benchmark-cloud.sh#L37) for motivation. [#39968](https://github.com/ClickHouse/ClickHouse/pull/39968) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Adds `parseDateTime64BestEffortUS`, `parseDateTime64BestEffortUSOrNull`, `parseDateTime64BestEffortUSOrZero` functions, closing [#37492](https://github.com/ClickHouse/ClickHouse/issues/37492).

* Display server-side time in `clickhouse-benchmark` by default if it is available (since ClickHouse version 22.8). This is needed to correctly compare the performance of clouds. This behavior can be changed with the new `--client-side-time` command line option. Change the `--randomize` command line option from `--randomize 1` to the form without argument. [#40193](https://github.com/ClickHouse/ClickHouse/pull/40193) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* 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)).

* 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)).

* [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)).

### <a id="227"></a> ClickHouse release 22.7, 2022-07-21
#### Upgrade Notes
* Enable setting `enable_positional_arguments` by default. It allows queries like `SELECT ... ORDER BY 1, 2` where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. [#38204](https://github.com/ClickHouse/ClickHouse/pull/38204) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Disable `format_csv_allow_single_quotes` by default. See [#37096](https://github.com/ClickHouse/ClickHouse/issues/37096). ([Kruglov Pavel](https://github.com/Avogar)).
* `Ordinary` database engine and old storage definition syntax for `*MergeTree` tables are deprecated. By default it's not possible to create new databases with `Ordinary` engine. If `system` database has `Ordinary` engine it will be automatically converted to `Atomic` on server startup. There are settings to keep old behavior (`allow_deprecated_database_ordinary` and `allow_deprecated_syntax_for_merge_tree`), but these settings may be removed in future releases. [#38335](https://github.com/ClickHouse/ClickHouse/pull/38335) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Force rewriting comma join to inner by default (set default value `cross_to_inner_join_rewrite = 2`). To have old behavior set `cross_to_inner_join_rewrite = 1`. [#39326](https://github.com/ClickHouse/ClickHouse/pull/39326) ([Vladimir C](https://github.com/vdimir)). If you will face any incompatibilities, you can turn this setting back.

### <a id="226"></a> ClickHouse release 22.6, 2022-06-16
#### Backward Incompatible Change
* Remove support for octal number literals in SQL. In previous versions they were parsed as Float64. [#37765](https://github.com/ClickHouse/ClickHouse/pull/37765) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Changes how settings using `seconds` as type are parsed to support floating point values (for example: `max_execution_time=0.5`). Infinity or NaN values will throw an exception. [#37187](https://github.com/ClickHouse/ClickHouse/pull/37187) ([Raúl Marín](https://github.com/Algunenano)).
* Changed format of binary serialization of columns of experimental type `Object`. New format is more convenient to implement by third-party clients. [#37482](https://github.com/ClickHouse/ClickHouse/pull/37482) ([Anton Popov](https://github.com/CurtizJ)).

* If you run different ClickHouse versions on a cluster with AArch64 CPU or mix AArch64 and amd64 on a cluster, and use distributed queries with GROUP BY multiple keys of fixed-size type that fit in 256 bits but don't fit in 64 bits, and the size of the result is huge, the data will not be fully aggregated in the result of these queries during upgrade. Workaround: upgrade with downtime instead of a rolling upgrade.
#### New Feature
* Add `GROUPING` function. It allows to disambiguate the records in the queries with `ROLLUP`, `CUBE` or `GROUPING SETS`. Closes [#19426](https://github.com/ClickHouse/ClickHouse/issues/19426). [#37163](https://github.com/ClickHouse/ClickHouse/pull/37163) ([Dmitry Novik](https://github.com/novikd)).

#### Performance Improvement
* Added numerous optimizations for ARM NEON [#38093](https://github.com/ClickHouse/ClickHouse/pull/38093)([Daniel Kutenin](https://github.com/danlark1)), ([Alexandra Pilipyuk](https://github.com/chalice19)) Note: if you run different ClickHouse versions on a cluster with ARM CPU and use distributed queries with GROUP BY multiple keys of fixed-size type that fit in 256 bits but don't fit in 64 bits, the result of the aggregation query will be wrong during upgrade. Workaround: upgrade with downtime instead of a rolling upgrade.
* Improve performance and memory usage for select of subset of columns for formats Native, Protobuf, CapnProto, JSONEachRow, TSKV, all formats with suffixes WithNames/WithNamesAndTypes. Previously while selecting only subset of columns from files in these formats all columns were read and stored in memory. Now only required columns are read. This PR enables setting `input_format_skip_unknown_fields` by default, because otherwise in case of select of subset of columns exception will be thrown.

### <a id="225"></a> ClickHouse release 22.5, 2022-05-19
#### Upgrade Notes
* Now, background merges, mutations and `OPTIMIZE` will not increment `SelectedRows` and `SelectedBytes` metrics. They (still) will increment `MergedRows` and `MergedUncompressedBytes` as it was before. This only affects the metric values, and makes them better. This change does not introduce any incompatibility, but you may wonder about the changes of metrics, so we put in this category. [#37040](https://github.com/ClickHouse/ClickHouse/pull/37040) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Updated the BoringSSL module to the official FIPS compliant version. This makes ClickHouse FIPS compliant. [#35914](https://github.com/ClickHouse/ClickHouse/pull/35914) ([Meena-Renganathan](https://github.com/Meena-Renganathan)). The ciphers `aes-192-cfb128` and `aes-256-cfb128` were removed, because they are not included in the FIPS certified version of BoringSSL.

The ciphers `aes-192-cfb128` and `aes-256-cfb128` were removed, because they are not included in the FIPS certified version of BoringSSL.
* `max_memory_usage` setting is removed from the default user profile in `users.xml`. This enables flexible memory limits for queries instead of the old rigid limit of 10 GB.
* Disable `log_query_threads` setting by default. It controls the logging of statistics about every thread participating in query execution. After supporting asynchronous reads, the total number of distinct thread ids became too large, and logging into the `query_thread_log` has become too heavy. [#37077](https://github.com/ClickHouse/ClickHouse/pull/37077) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

* Now date time conversion functions that generates time before 1970-01-01 00:00:00 with partial hours/minutes timezones will be saturated to zero instead of overflow. This is the continuation of https://github.com/ClickHouse/ClickHouse/pull/29953 which addresses https://github.com/ClickHouse/ClickHouse/pull/29953#discussion_r800550280 .

## Public Disclosure Timing
A public disclosure date is negotiated by the ClickHouse maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to 90 days. For a vulnerability with a straightforward mitigation, we expect report date to disclosure date to be on the order of 7 days.

Folder structure
______________
dump_dataset_from_ch.sh - bash script that dumps a dataset from Clickhouse
schema.sql - schema for a Greenplum cluster to load dumped dataset in
load_data_set.sql - the script that loads up a dumped dataset
queries.sql - SQL statements used in the benchmark
benchmark.sh - this piece of bash conducts a benchmark
result_parser.py - script to parse benchmark.sh's output and produce python code to build a graph to compare up to 4 benchmark results.
Requirements
____________
Greenplum uses a separate server as a point of entry, so you need 2 servers at least to run a cluster: master and segment hosts. 2 segments host and 56 segments(28 per host) had been used while conducting the test.
You has has to put segment hostnames in the benchmark.sh.
Greenplum quick installation instructions
_________________________________________
Obtain a stable Greenplum version here(4.3.9.1 was used while conducting the benchmark):
https://network.pivotal.io/products/pivotal-gpdb
and install it using this detailed guide:
http://gpdb.docs.pivotal.io/4340/install_guide/install_guide.html
You should change gp_interconnect_type to 'tcp' if cluster members are connected via 1GB link or lower.
There are some variables that has to be changed prior the first benchmark run: gp_vmem_protect_limit and max_statement_mem to allow each segment to use more virtual memory. Here are commands to change this GUCS that has to be executed as gpadmin at the master host:
gpconfig -c gp_interconnect_type -v tcp
gpconfig -c gp_vmem_protect_limit -v 3000
gpconfig -c max_statement_mem -v '4000MB'
How to prepare data
-------------------
One can prepare datasets to run the benchmark on using dump_dataset_from_ch.sh script from this repo. The script has to be run at at Clickhouse host. It takes a long time to get dumps.
Upload the datasets into Greenplum master.Then run schema.sql to prepare schema and load_data_set.sql to load data up. This operation also takes a long time.
How to conduct the benchmark
__________________________
There is a benchmark.sh that take some arguments. Here is the syntax:
./benchmark.sh sql_statements_file tablename dbname orca_switch
If you don't know about the last one then just use a default value.
