### <a id="228"></a> ClickHouse release 22.8, 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). [#40015](https://github.com/ClickHouse/ClickHouse/pull/40015) ([Tanya Bragin](https://github.com/tbragin)).
* Extend the `system.processors_profile_log` with more information such as input rows. [#40121](https://github.com/ClickHouse/ClickHouse/pull/40121) ([Amos Bird](https://github.com/amosbird)).
* 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)).
* Add metrics for filesystem cache: `FilesystemCacheSize` and `FilesystemCacheElements`. [#40260](https://github.com/ClickHouse/ClickHouse/pull/40260) ([Kseniia Sumarokova](https://github.com/kssenii)).

* 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).

# 2022 Changelog
### ClickHouse release v22.8.1.2097-lts (09a2ff88435) FIXME as compared to v22.7.1.2484-stable (f4f05ec786a)
#### Backward Incompatible Change
* Make 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 [#36140](https://github.com/ClickHouse/ClickHouse/issues/36140). Closes [#37889](https://github.com/ClickHouse/ClickHouse/issues/37889). [#36171](https://github.com/ClickHouse/ClickHouse/pull/36171) ([Kseniia Sumarokova](https://github.com/kssenii)).
* 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)).
* 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)).
#### New Feature
* 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)).
* Add SLRU cache policy for uncompressed cache and marks cache. [#34651](https://github.com/ClickHouse/ClickHouse/pull/34651) ([alexX512](https://github.com/alexX512)).
* 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)).
* Add concurrent_threads_soft_limit parameter to increase performance in case of high RPS 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)).
* 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)).
* Added support for parallel distributed insert select 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)).
* This feature will provide JSON formatted log output in console. 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)).
* 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. [#39494](https://github.com/ClickHouse/ClickHouse/pull/39494) ([Robert Schulze](https://github.com/rschu1ze)).
* 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 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)).
* adds 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)).
* 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)).
#### Performance Improvement
* * Break on analyze stuck on complex query. [#38185](https://github.com/ClickHouse/ClickHouse/pull/38185) ([Vladimir C](https://github.com/vdimir)).
* 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)).
* `DISTINCT` in order with `ORDER BY` improves memory usage (significantly) and query execution time if `DISTINCT` columns match (or form a prefix of) `ORDER BY` columns. [#39432](https://github.com/ClickHouse/ClickHouse/pull/39432) ([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)).
* 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)).
* `DistinctSortedTransform` didn't take advantage of sorting, i.e. it worked like ordinary `DISTINCT` implementation. The fix reduces memory usage significantly. [#39538](https://github.com/ClickHouse/ClickHouse/pull/39538) ([Igor Nikonov](https://github.com/devcrafter)).
* ColumnVector: optimize filter with AVX512VBMI2 compress store. [#39633](https://github.com/ClickHouse/ClickHouse/pull/39633) ([Guo Wangyang](https://github.com/guowangy)).
* KeyCondition: optimize applyFunction in multi-thread scenario. [#39812](https://github.com/ClickHouse/ClickHouse/pull/39812) ([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)).
* - 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)).
#### Improvement
* Change the way how PK is analyzed for MergeTree. [#25563](https://github.com/ClickHouse/ClickHouse/pull/25563) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* - 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)).
* 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)).
* `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)).
* 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)).
* - Simplified function registration macro interface (`FUNCTION_REGISTER*`) to eliminate the step to add and call an extern function in the registerFunctions.cpp, it also makes incremental builds of a new function faster. [#38615](https://github.com/ClickHouse/ClickHouse/pull/38615) ([Li Yin](https://github.com/liyinsg)).
* * Added support of `LEFT SEMI` and `LEFT ANTI` direct join with rocksdb. [#38956](https://github.com/ClickHouse/ClickHouse/pull/38956) ([Vladimir C](https://github.com/vdimir)).
* resolves [#37490](https://github.com/ClickHouse/ClickHouse/issues/37490). [#39054](https://github.com/ClickHouse/ClickHouse/pull/39054) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
* Store Keeper API version inside a predefined path. [#39096](https://github.com/ClickHouse/ClickHouse/pull/39096) ([Antonio Andelic](https://github.com/antonio2368)).
* Now entrypoint.sh in docker image creates and executes chown for all folders it found in config for multidisk setup [#17717](https://github.com/ClickHouse/ClickHouse/issues/17717). [#39121](https://github.com/ClickHouse/ClickHouse/pull/39121) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Add profile events for fsync. [#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 got 200OK. [#39244](https://github.com/ClickHouse/ClickHouse/pull/39244) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Improved Base58 encoding/decoding. [#39292](https://github.com/ClickHouse/ClickHouse/pull/39292) ([Andrey Zvonov](https://github.com/zvonand)).
* Normalize `AggregateFunction` types and state representations because optimizations like 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)).
* Improved memory usage during memory efficient merging of aggregation results. [#39429](https://github.com/ClickHouse/ClickHouse/pull/39429) ([Nikita Taranov](https://github.com/nickitat)).
* 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)).
* Rework and simplify the `system.backups` table, remove the `internal` column, allow user to set 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)).
* Refactored a little code, removed duplicate code. [#39509](https://github.com/ClickHouse/ClickHouse/pull/39509) ([Simon Liu](https://github.com/monadbobo)).
* 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)).
* Improve bytes to bits mask transform for SSE/AVX/AVX512. [#39586](https://github.com/ClickHouse/ClickHouse/pull/39586) ([Guo Wangyang](https://github.com/guowangy)).
* Add formats `PrettyMonoBlock`, `PrettyNoEscapesMonoBlock`, `PrettyCompactNoEscapes`, `PrettyCompactNoEscapesMonoBlock`, `PrettySpaceNoEscapes`, `PrettySpaceMonoBlock`, `PrettySpaceNoEscapesMonoBlock`. [#39646](https://github.com/ClickHouse/ClickHouse/pull/39646) ([Kruglov Pavel](https://github.com/Avogar)).
* 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 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)).
* 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)).
* Parameters are now transferred in `Query` packets right after the query text in the same serialisation format as the settings. [#39906](https://github.com/ClickHouse/ClickHouse/pull/39906) ([Nikita Taranov](https://github.com/nickitat)).
* 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)).
* 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). [#40015](https://github.com/ClickHouse/ClickHouse/pull/40015) ([Tanya Bragin](https://github.com/tbragin)).
* * Add observer mode to (zoo)keeper cluster discovery feature. In this mode node itself doesn't belong to cluster. [#40035](https://github.com/ClickHouse/ClickHouse/pull/40035) ([Vladimir C](https://github.com/vdimir)).
* 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)).
* Extend processors_profile_log with more information such as input rows. [#40121](https://github.com/ClickHouse/ClickHouse/pull/40121) ([Amos Bird](https://github.com/amosbird)).
* 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). [#40184](https://github.com/ClickHouse/ClickHouse/pull/40184) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* 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)).
* Add current metrics for fs cache: `FilesystemCacheSize` and `FilesystemCacheElements`. [#40260](https://github.com/ClickHouse/ClickHouse/pull/40260) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Add support for LARGE_BINARY/LARGE_STRING with Arrow (Closes [#32401](https://github.com/ClickHouse/ClickHouse/issues/32401)). [#40293](https://github.com/ClickHouse/ClickHouse/pull/40293) ([Josh Taylor](https://github.com/joshuataylor)).
#### Bug Fix
* 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)).
* Fix seeking while reading from encrypted disk. This PR fixes [#38381](https://github.com/ClickHouse/ClickHouse/issues/38381). [#39687](https://github.com/ClickHouse/ClickHouse/pull/39687) ([Vitaly Baranov](https://github.com/vitlibar)).
* * Fix duplicate columns in join plan. Finally, solve [#26809](https://github.com/ClickHouse/ClickHouse/issues/26809). [#40009](https://github.com/ClickHouse/ClickHouse/pull/40009) ([Vladimir C](https://github.com/vdimir)).
#### Build/Testing/Packaging Improvement
* Prebuild ClickHouse x86 binaries now require support for AVX instructions, i.e. a CPU not older than Intel Sandy Bridge / AMD Bulldozer, both released in 2011. [#39000](https://github.com/ClickHouse/ClickHouse/pull/39000) ([Robert Schulze](https://github.com/rschu1ze)).
* 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)).
* Fix LSan by fixing getauxval(). [#39430](https://github.com/ClickHouse/ClickHouse/pull/39430) ([Azat Khuzhin](https://github.com/azat)).

[#39450](https://github.com/ClickHouse/ClickHouse/pull/39450) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Remove the option to build ClickHouse tools as separate executable programs. This fixes [#37847](https://github.com/ClickHouse/ClickHouse/issues/37847). [#39520](https://github.com/ClickHouse/ClickHouse/pull/39520) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fixed Unit tests for wide integers on s390x. [#39627](https://github.com/ClickHouse/ClickHouse/pull/39627) ([Harry Lee](https://github.com/HarryLeeIBM)).
* Increase max cache size for clang-tidy builds. Try to avoid flushing it out between builds. [#39652](https://github.com/ClickHouse/ClickHouse/pull/39652) ([Nikita Taranov](https://github.com/nickitat)).
* No need to use fixed IP when you are using cluster with SSL. Using the same fixed IP could trigger collision between tests. At this change the server's certificate is generated for a designated host name (see server-ext.cnf at each test). The client should check server's certificate against that name accordingly. [#40007](https://github.com/ClickHouse/ClickHouse/pull/40007) ([Sema Checherinda](https://github.com/CheSema)).
* Support build with `clang-16` (trunk). This closes [#39949](https://github.com/ClickHouse/ClickHouse/issues/39949). [#40181](https://github.com/ClickHouse/ClickHouse/pull/40181) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Prepare RISC-V 64 build to run in CI. This is for [#40141](https://github.com/ClickHouse/ClickHouse/issues/40141). [#40197](https://github.com/ClickHouse/ClickHouse/pull/40197) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

* Fix bug in schema inference in case of empty messages in Protobuf/CapnProto formats that allowed to create column with empty `Tuple` type. Closes [#39051](https://github.com/ClickHouse/ClickHouse/issues/39051) Add 2 new settings `input_format_{protobuf/capnproto}_skip_fields_with_unsupported_types_in_schema_inference` that allow to skip fields with unsupported types while schema inference for Protobuf and CapnProto formats. [#39357](https://github.com/ClickHouse/ClickHouse/pull/39357) ([Kruglov Pavel](https://github.com/Avogar)).
* Fix segmentation fault on `CREATE WINDOW VIEW .. ON CLUSTER ... INNER`. Closes [#39363](https://github.com/ClickHouse/ClickHouse/issues/39363). [#39384](https://github.com/ClickHouse/ClickHouse/pull/39384) ([Kseniia Sumarokova](https://github.com/kssenii)).

Closes [#39094](https://github.com/ClickHouse/ClickHouse/issues/39094) Closes [#33652](https://github.com/ClickHouse/ClickHouse/issues/33652). [#39498](https://github.com/ClickHouse/ClickHouse/pull/39498) ([Kruglov Pavel](https://github.com/Avogar)).
* Fix rare bug in asynchronous reading (with setting `local_filesystem_read_method='pread_threadpool'`) with enabled `O_DIRECT` (enabled by setting `min_bytes_to_use_direct_io`). [#39506](https://github.com/ClickHouse/ClickHouse/pull/39506) ([Anton Popov](https://github.com/CurtizJ)).
* Fixes "Code: 49. DB::Exception: FunctionFactory: the function name '' is not unique. (LOGICAL_ERROR)" observed on FreeBSD when starting clickhouse. [#39551](https://github.com/ClickHouse/ClickHouse/pull/39551) ([Alexander Gololobov](https://github.com/davenger)).
* Fix bug with maxsplit argument for splitByChar, which was not working correctly. [#39552](https://github.com/ClickHouse/ClickHouse/pull/39552) ([filimonov](https://github.com/filimonov)).
* * Fix bug in ASOF JOIN with `enable_optimize_predicate_expression`, close [#37813](https://github.com/ClickHouse/ClickHouse/issues/37813). [#39556](https://github.com/ClickHouse/ClickHouse/pull/39556) ([Vladimir C](https://github.com/vdimir)).
* Fixed `CREATE/DROP INDEX` query with `ON CLUSTER` or `Replicated` database and `ReplicatedMergeTree`. It used to be executed on all replicas (causing error or DDL queue stuck). Fixes [#39511](https://github.com/ClickHouse/ClickHouse/issues/39511). [#39565](https://github.com/ClickHouse/ClickHouse/pull/39565) ([Alexander Tokmakov](https://github.com/tavplubix)).

* Fixed point of origin for exponential decay window functions to the last value in window. Previously, decay was calculated by formula `exp((t - curr_row_t) / decay_length)`, which is incorrect when right boundary of window is not `CURRENT ROW`. It was changed to: `exp((t - last_row_t) / decay_length)`. There is no change in results for windows with `ROWS BETWEEN (smth) AND CURRENT ROW`. [#39593](https://github.com/ClickHouse/ClickHouse/pull/39593) ([Vladimir Chebotaryov](https://github.com/quickhouse)).

This is for the case when you have Linux machine and want to use it to build `clickhouse` binary that will run on another Linux machine with RISC-V 64 CPU architecture. This is intended for continuous integration checks that run on Linux servers.

# MaterializedPostgreSQL
Creates ClickHouse table with an initial data dump of PostgreSQL table and starts replication process, i.e. executes background job to apply new changes as they happen on PostgreSQL table in the remote PostgreSQL database.
If more than one table is required, it is highly recommended to use the [MaterializedPostgreSQL](../../../engines/database-engines/materialized-postgresql.md) database engine instead of the table engine and use the `materialized_postgresql_tables_list` setting, which specifies the tables to be replicated (will also be possible to add database `schema`). It will be much better in terms of CPU, fewer connections and fewer replication slots inside the remote PostgreSQL database.

When merging, `ReplacingMergeTree` from all the rows with the same sorting key leaves only one:
When merging, `ReplacingMergeTree` from all the rows with the same sorting key leaves only one:
- The last in the selection, if `ver` not set. A selection is a set of rows in a set of parts participating in the merge. The most recently created part (the last insert) will be the last one in the selection. Thus, after deduplication, the very last row from the most recent insert will remain for each unique sorting key.
- With the maximum version, if `ver` specified. If `ver` is the same for several rows, then it will use "if `ver` is not specified" rule for them, i.e. the most recent inserted row will remain.
Example:
```sql
-- without ver - the last inserted 'wins'
CREATE TABLE myFirstReplacingMT
(
`key` Int64,
`someCol` String,
`eventTime` DateTime
)
ENGINE = ReplacingMergeTree
ORDER BY key;
INSERT INTO myFirstReplacingMT Values (1, 'first', '2020-01-01 01:01:01');
INSERT INTO myFirstReplacingMT Values (1, 'second', '2020-01-01 00:00:00');
SELECT * FROM myFirstReplacingMT FINAL;
