 # 2023 Changelog
 
+### <a id="232"></a> ClickHouse release 23.2, 2023-02-23
+
+#### Backward Incompatible Change
+* Extend function "toDayOfWeek()" (alias: "DAYOFWEEK") with a mode argument that encodes whether the week starts on Monday or Sunday and whether counting starts at 0 or 1. For consistency with other date time functions, the mode argument was inserted between the time and the time zone arguments. This breaks existing usage of the (previously undocumented) 2-argument syntax "toDayOfWeek(time, time_zone)". A fix is to rewrite the function into "toDayOfWeek(time, 0, time_zone)". [#45233](https://github.com/ClickHouse/ClickHouse/pull/45233) ([Robert Schulze](https://github.com/rschu1ze)).
+* Rename setting `max_query_cache_size` to `filesystem_cache_max_download_size`. [#45614](https://github.com/ClickHouse/ClickHouse/pull/45614) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* The `default` user will not have permissions for access type `SHOW NAMED COLLECTION` by default (e.g. `default` user will no longer be able to grant ALL to other users as it was before, therefore this PR is backward incompatible). [#46010](https://github.com/ClickHouse/ClickHouse/pull/46010) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* If the SETTINGS clause is specified before the FORMAT clause, the settings will be applied to formatting as well. [#46003](https://github.com/ClickHouse/ClickHouse/pull/46003) ([Azat Khuzhin](https://github.com/azat)).
+* Remove support for setting `materialized_postgresql_allow_automatic_update` (which was by default turned off). [#46106](https://github.com/ClickHouse/ClickHouse/pull/46106) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Slightly improve performance of `countDigits` on realistic datasets. This closed [#44518](https://github.com/ClickHouse/ClickHouse/issues/44518). In previous versions, `countDigits(0)` returned `0`; now it returns `1`, which is more correct, and follows the existing documentation. [#46187](https://github.com/ClickHouse/ClickHouse/pull/46187) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Disallow creation of new columns compressed by a combination of codecs "Delta" or "DoubleDelta" followed by codecs "Gorilla" or "FPC". This can be bypassed using setting "allow_suspicious_codecs = true". [#45652](https://github.com/ClickHouse/ClickHouse/pull/45652) ([Robert Schulze](https://github.com/rschu1ze)).
+
+#### New Feature
+* Add `StorageIceberg` and table function `iceberg` to access iceberg table store on S3. [#45384](https://github.com/ClickHouse/ClickHouse/pull/45384) ([flynn](https://github.com/ucasfl)).
+* Allow configuring storage as `SETTINGS disk = '<disk_name>'` (instead of `storage_policy`) and with explicit disk creation `SETTINGS disk = disk(type=s3, ...)`. [#41976](https://github.com/ClickHouse/ClickHouse/pull/41976) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Expose `ProfileEvents` counters in `system.part_log`. [#38614](https://github.com/ClickHouse/ClickHouse/pull/38614) ([Bharat Nallan](https://github.com/bharatnc)).
+* Enrichment of the existing `ReplacingMergeTree` engine to allow duplicate the insertion. It leverages the power of both `ReplacingMergeTree` and `CollapsingMergeTree` in one MergeTree engine. Deleted data are not returned when queried, but not removed from disk neither. [#41005](https://github.com/ClickHouse/ClickHouse/pull/41005) ([youennL-cs](https://github.com/youennL-cs)).
+* Add `generateULID` function. Closes [#36536](https://github.com/ClickHouse/ClickHouse/issues/36536). [#44662](https://github.com/ClickHouse/ClickHouse/pull/44662) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Add `corrMatrix` aggregate function, calculating each two columns. In addition, since Aggregatefunctions `covarSamp` and `covarPop` are similar to `corr`, I add `covarSampMatrix`, `covarPopMatrix` by the way. @alexey-milovidov closes [#44587](https://github.com/ClickHouse/ClickHouse/issues/44587). [#44680](https://github.com/ClickHouse/ClickHouse/pull/44680) ([FFFFFFFHHHHHHH](https://github.com/FFFFFFFHHHHHHH)).
+* Introduce arrayShuffle function for random array permutations. [#45271](https://github.com/ClickHouse/ClickHouse/pull/45271) ([Joanna Hulboj](https://github.com/jh0x)).
+* Support types `FIXED_SIZE_BINARY` type in Arrow, `FIXED_LENGTH_BYTE_ARRAY` in `Parquet` and match them to `FixedString`. Add settings `output_format_parquet_fixed_string_as_fixed_byte_array/output_format_arrow_fixed_string_as_fixed_byte_array` to control default output type for FixedString. Closes [#45326](https://github.com/ClickHouse/ClickHouse/issues/45326). [#45340](https://github.com/ClickHouse/ClickHouse/pull/45340) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add a new column `last_exception_time` to system.replication_queue. [#45457](https://github.com/ClickHouse/ClickHouse/pull/45457) ([Frank Chen](https://github.com/FrankChen021)).
+* Add two new functions which allow for user-defined keys/seeds with SipHash{64,128}. [#45513](https://github.com/ClickHouse/ClickHouse/pull/45513) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
+* Allow a three-argument version for table function `format`. close [#45808](https://github.com/ClickHouse/ClickHouse/issues/45808). [#45873](https://github.com/ClickHouse/ClickHouse/pull/45873) ([FFFFFFFHHHHHHH](https://github.com/FFFFFFFHHHHHHH)).
+* Add `JodaTime` format support for 'x','w','S'. Refer to https://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html. [#46073](https://github.com/ClickHouse/ClickHouse/pull/46073) ([zk_kiger](https://github.com/zk-kiger)).
+* Support window function `ntile`. ([lgbo](https://github.com/lgbo-ustc)).
+* Add setting `final` to implicitly apply the `FINAL` modifier to every table. [#40945](https://github.com/ClickHouse/ClickHouse/pull/40945) ([Arthur Passos](https://github.com/arthurpassos)).
+* Added `arrayPartialSort` and `arrayPartialReverseSort` functions. [#46296](https://github.com/ClickHouse/ClickHouse/pull/46296) ([Joanna Hulboj](https://github.com/jh0x)).
+* The new http parameter `client_protocol_version` allows setting a client protocol version for HTTP responses using the Native format. [#40397](https://github.com/ClickHouse/ClickHouse/issues/40397). [#46360](https://github.com/ClickHouse/ClickHouse/pull/46360) ([Geoff Genz](https://github.com/genzgd)).
+* Add new function `regexpExtract`, like spark function `REGEXP_EXTRACT` for compatibility. It is similar to the existing function `extract`. [#46469](https://github.com/ClickHouse/ClickHouse/pull/46469) ([李扬](https://github.com/taiyang-li)).
+* Add new function `JSONArrayLength`, which returns the number of elements in the outermost JSON array. The function returns NULL if the input JSON string is invalid. [#46631](https://github.com/ClickHouse/ClickHouse/pull/46631) ([李扬](https://github.com/taiyang-li)).
+
+#### Performance Improvement
+* The introduced logic works if PREWHERE condition is a conjunction of multiple conditions (cond1 AND cond2 AND ... ). It groups those conditions that require reading the same columns into steps. After each step the corresponding part of the full condition is computed and the result rows might be filtered. This allows to read fewer rows in the next steps thus saving IO bandwidth and doing less computation. This logic is disabled by default for now. It will be enabled by default in one of the future releases once it is known to not have any regressions, so it is highly encouraged to be used for testing. It can be controlled by 2 settings: "enable_multiple_prewhere_read_steps" and "move_all_conditions_to_prewhere". [#46140](https://github.com/ClickHouse/ClickHouse/pull/46140) ([Alexander Gololobov](https://github.com/davenger)).
+* An option added to aggregate partitions independently if table partition key and group by key are compatible. Controlled by the setting `allow_aggregate_partitions_independently`. Disabled by default because of limited applicability (please refer to the docs). [#45364](https://github.com/ClickHouse/ClickHouse/pull/45364) ([Nikita Taranov](https://github.com/nickitat)).
+* Allow using Vertical merge algorithm with parts in Compact format. This will allow ClickHouse server to use much less memory for background operations. This closes [#46084](https://github.com/ClickHouse/ClickHouse/issues/46084). [#45681](https://github.com/ClickHouse/ClickHouse/pull/45681) [#46282](https://github.com/ClickHouse/ClickHouse/pull/46282) ([Anton Popov](https://github.com/CurtizJ)).
+* Optimize `Parquet` reader by using batch reader. [#45878](https://github.com/ClickHouse/ClickHouse/pull/45878) ([LiuNeng](https://github.com/liuneng1994)).
+* Add new `local_filesystem_read_method` method `io_uring` based on the asynchronous Linux [io_uring](https://kernel.dk/io_uring.pdf) subsystem, improving read performance almost universally compared to the default `pread` method. [#38456](https://github.com/ClickHouse/ClickHouse/pull/38456) ([Saulius Valatka](https://github.com/sauliusvl)).
+* Rewrite aggregate functions with `if` expression as argument when logically equivalent. For example, `avg(if(cond, col, null))` can be rewritten to avgIf(cond, col). It is helpful in performance. [#44730](https://github.com/ClickHouse/ClickHouse/pull/44730) ([李扬](https://github.com/taiyang-li)).
+* Improve lower/upper function performance with avx512 instructions. [#37894](https://github.com/ClickHouse/ClickHouse/pull/37894) ([yaqi-zhao](https://github.com/yaqi-zhao)).
+* Remove the limitation that on systems with >=32 cores and SMT disabled ClickHouse uses only half of the cores (the case when you disable Hyper Threading in BIOS). [#44973](https://github.com/ClickHouse/ClickHouse/pull/44973) ([Robert Schulze](https://github.com/rschu1ze)).
+* Improve performance of function `multiIf` by columnar executing, speed up by 2.3x. [#45296](https://github.com/ClickHouse/ClickHouse/pull/45296) ([李扬](https://github.com/taiyang-li)).
+* Add fast path for function `position` when the needle is empty. [#45382](https://github.com/ClickHouse/ClickHouse/pull/45382) ([李扬](https://github.com/taiyang-li)).
+* Enable `query_plan_remove_redundant_sorting` optimization by default. Optimization implemented in [#45420](https://github.com/ClickHouse/ClickHouse/issues/45420). [#45567](https://github.com/ClickHouse/ClickHouse/pull/45567) ([Igor Nikonov](https://github.com/devcrafter)).
+* Increased HTTP Transfer Encoding chunk size to improve performance of large queries using the HTTP interface. [#45593](https://github.com/ClickHouse/ClickHouse/pull/45593) ([Geoff Genz](https://github.com/genzgd)).
+* Fixed performance of short `SELECT` queries that read from tables with large number of `Array`/`Map`/`Nested` columns. [#45630](https://github.com/ClickHouse/ClickHouse/pull/45630) ([Anton Popov](https://github.com/CurtizJ)).
+* Improve performance of filtering for big integers and decimal types. [#45949](https://github.com/ClickHouse/ClickHouse/pull/45949) ([李扬](https://github.com/taiyang-li)).
+* This change could effectively reduce the overhead of obtaining the filter from ColumnNullable(UInt8) and improve the overall query performance. To evaluate the impact of this change, we adopted TPC-H benchmark but revised the column types from non-nullable to nullable, and we measured the QPS of its queries as the performance indicator. [#45962](https://github.com/ClickHouse/ClickHouse/pull/45962) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Make the `_part` and `_partition_id` virtual column be `LowCardinality(String)` type. Closes [#45964](https://github.com/ClickHouse/ClickHouse/issues/45964). [#45975](https://github.com/ClickHouse/ClickHouse/pull/45975) ([flynn](https://github.com/ucasfl)).
+* Improve the performance of Decimal conversion when the scale does not change. [#46095](https://github.com/ClickHouse/ClickHouse/pull/46095) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow to increase prefetching for read data. [#46168](https://github.com/ClickHouse/ClickHouse/pull/46168) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Rewrite `arrayExists(x -> x = 1, arr)` -> `has(arr, 1)`, which improve performance by 1.34x. [#46188](https://github.com/ClickHouse/ClickHouse/pull/46188) ([李扬](https://github.com/taiyang-li)).
+* Fix too big memory usage for vertical merges on non-remote disk. Respect `max_insert_delayed_streams_for_parallel_write` for the remote disk. [#46275](https://github.com/ClickHouse/ClickHouse/pull/46275) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Update zstd to v1.5.4. It has some minor improvements in performance and compression ratio. If you run replicas with different versions of ClickHouse you may see reasonable error messages `Data after merge/mutation is not byte-identical to data on another replicas.` with explanation. These messages are Ok and you should not worry. [#46280](https://github.com/ClickHouse/ClickHouse/pull/46280) ([Raúl Marín](https://github.com/Algunenano)).
+* Fix performance degradation caused by [#39737](https://github.com/ClickHouse/ClickHouse/issues/39737). [#46309](https://github.com/ClickHouse/ClickHouse/pull/46309) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The `replicas_status` handle will answer quickly even in case of a large replication queue. [#46310](https://github.com/ClickHouse/ClickHouse/pull/46310) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add avx512 support for aggregate function `sum`, function unary arithmetic, function comparison. [#37870](https://github.com/ClickHouse/ClickHouse/pull/37870) ([zhao zhou](https://github.com/zzachimed)).
+* Rewrote the code around marks distribution and the overall coordination of the reading in order to achieve the maximum performance improvement. This closes [#34527](https://github.com/ClickHouse/ClickHouse/issues/34527). [#43772](https://github.com/ClickHouse/ClickHouse/pull/43772) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Remove redundant DISTINCT clauses in query (subqueries). Implemented on top of query plan. It does similar optimization as `optimize_duplicate_order_by_and_distinct` regarding DISTINCT clauses. Can be enabled via `query_plan_remove_redundant_distinct` setting. Related to [#42648](https://github.com/ClickHouse/ClickHouse/issues/42648). [#44176](https://github.com/ClickHouse/ClickHouse/pull/44176) ([Igor Nikonov](https://github.com/devcrafter)).
+* A few query rewrite optimizations: `sumIf(123, cond) -> 123 * countIf(1, cond)`, `sum(if(cond, 123, 0)) -> 123 * countIf(cond)`, `sum(if(cond, 0, 123)) -> 123 * countIf(not(cond))` [#44728](https://github.com/ClickHouse/ClickHouse/pull/44728) ([李扬](https://github.com/taiyang-li)).
+* Improved how memory bound merging and aggregation in order on top query plan interact. Previously we fell back to explicit sorting for AIO in some cases when it wasn't actually needed. [#45892](https://github.com/ClickHouse/ClickHouse/pull/45892) ([Nikita Taranov](https://github.com/nickitat)).
+* Concurrent merges are scheduled using round-robin by default to ensure fair and starvation-free operation. Previously in heavily overloaded shards, big merges could possibly be starved by smaller merges due to the use of strict priority scheduling. Added `background_merges_mutations_scheduling_policy` server config option to select scheduling algorithm (`round_robin` or `shortest_task_first`). [#46247](https://github.com/ClickHouse/ClickHouse/pull/46247) ([Sergei Trifonov](https://github.com/serxa)).
+

+* Enable retries for INSERT by default in case of ZooKeeper session loss. We already use it in production. [#46308](https://github.com/ClickHouse/ClickHouse/pull/46308) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add ability to ignore unknown keys in JSON object for named tuples (`input_format_json_ignore_unknown_keys_in_named_tuple`). [#45678](https://github.com/ClickHouse/ClickHouse/pull/45678) ([Azat Khuzhin](https://github.com/azat)).
+* Support optimizing the `where` clause with sorting key expression move to `prewhere`  for query with `final`. [#38893](https://github.com/ClickHouse/ClickHouse/issues/38893). [#38950](https://github.com/ClickHouse/ClickHouse/pull/38950) ([hexiaoting](https://github.com/hexiaoting)).
+* Add new metrics for backups: num_processed_files and processed_files_size described actual number of processed files. [#42244](https://github.com/ClickHouse/ClickHouse/pull/42244) ([Aleksandr](https://github.com/AVMusorin)).
+* Added retries on interserver DNS errors. [#43179](https://github.com/ClickHouse/ClickHouse/pull/43179) ([Anton Kozlov](https://github.com/tonickkozlov)).
+* Keeper improvement: try preallocating space on the disk to avoid undefined out-of-space issues. Introduce setting `max_log_file_size` for the maximum size of Keeper's Raft log files. [#44370](https://github.com/ClickHouse/ClickHouse/pull/44370) ([Antonio Andelic](https://github.com/antonio2368)).
+* Optimize behavior for a replica delay api logic in case the replica is read-only. [#45148](https://github.com/ClickHouse/ClickHouse/pull/45148) ([mateng915](https://github.com/mateng0915)).

+* Save exception stack trace in part_log. [#45459](https://github.com/ClickHouse/ClickHouse/pull/45459) ([Frank Chen](https://github.com/FrankChen021)).
+* The `regexp_tree` dictionary is polished and now it is compatible with https://github.com/ua-parser/uap-core. [#45631](https://github.com/ClickHouse/ClickHouse/pull/45631) ([Han Fei](https://github.com/hanfei1991)).
+* Updated checking of `SYSTEM SYNC REPLICA`, resolves [#45508](https://github.com/ClickHouse/ClickHouse/issues/45508) [#45648](https://github.com/ClickHouse/ClickHouse/pull/45648) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Rename setting `replication_alter_partitions_sync` to `alter_sync`. [#45659](https://github.com/ClickHouse/ClickHouse/pull/45659) ([Antonio Andelic](https://github.com/antonio2368)).
+* The `generateRandom` table function and the engine now support `LowCardinality` data types. This is useful for testing, for example you can write `INSERT INTO table SELECT * FROM generateRandom() LIMIT 1000`. This is needed to debug [#45590](https://github.com/ClickHouse/ClickHouse/issues/45590). [#45661](https://github.com/ClickHouse/ClickHouse/pull/45661) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The experimental query result cache now provides more modular configuration settings. [#45679](https://github.com/ClickHouse/ClickHouse/pull/45679) ([Robert Schulze](https://github.com/rschu1ze)).
+* Renamed "query result cache" to "query cache". [#45682](https://github.com/ClickHouse/ClickHouse/pull/45682) ([Robert Schulze](https://github.com/rschu1ze)).
+* add `SYSTEM SYNC FILE CACHE` command. It will do the `sync` syscall. [#8921](https://github.com/ClickHouse/ClickHouse/issues/8921). [#45685](https://github.com/ClickHouse/ClickHouse/pull/45685) ([DR](https://github.com/freedomDR)).
+* Add a new S3 setting `allow_head_object_request`. This PR makes usage of `GetObjectAttributes` request instead of `HeadObject` introduced in https://github.com/ClickHouse/ClickHouse/pull/45288 optional (and disabled by default). [#45701](https://github.com/ClickHouse/ClickHouse/pull/45701) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Add ability to override connection settings based on connection names (that said that now you can forget about storing password for each connection, you can simply put everything into `~/.clickhouse-client/config.xml` and even use different history files for them, which can be also useful). [#45715](https://github.com/ClickHouse/ClickHouse/pull/45715) ([Azat Khuzhin](https://github.com/azat)).
+* Arrow format: support the duration type. Closes [#45669](https://github.com/ClickHouse/ClickHouse/issues/45669). [#45750](https://github.com/ClickHouse/ClickHouse/pull/45750) ([flynn](https://github.com/ucasfl)).

+* Hide password in logs when a table function's arguments are specified with a named collection. [#45774](https://github.com/ClickHouse/ClickHouse/pull/45774) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Improve internal S3 client to correctly deduce regions and redirections for different types of URLs. [#45783](https://github.com/ClickHouse/ClickHouse/pull/45783) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add support for Map, IPv4 and IPv6 types in generateRandom. Mostly useful for testing. [#45785](https://github.com/ClickHouse/ClickHouse/pull/45785) ([Raúl Marín](https://github.com/Algunenano)).
+* Support empty/notEmpty for IP types. [#45799](https://github.com/ClickHouse/ClickHouse/pull/45799) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* The column `num_processed_files` was split into two columns: `num_files` (for BACKUP) and `files_read` (for RESTORE). The column `processed_files_size` was split into two columns: `total_size` (for BACKUP) and `bytes_read` (for RESTORE). [#45800](https://github.com/ClickHouse/ClickHouse/pull/45800) ([Vitaly Baranov](https://github.com/vitlibar)).

+* Add reference implementation for SipHash128. [#46065](https://github.com/ClickHouse/ClickHouse/pull/46065) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
+* Add a new metric to record allocations times and bytes using mmap. [#46068](https://github.com/ClickHouse/ClickHouse/pull/46068) ([李扬](https://github.com/taiyang-li)).
+* Currently for functions like `leftPad`, `rightPad`, `leftPadUTF8`, `rightPadUTF8`, the second argument `length` must be UInt8|16|32|64|128|256. Which is too strict for clickhouse users, besides, it is not consistent with other similar functions like `arrayResize`, `substring` and so on. [#46103](https://github.com/ClickHouse/ClickHouse/pull/46103) ([李扬](https://github.com/taiyang-li)).
+* Fix assertion in the `welchTTest` function in debug build when the resulting statistics is NaN. Unified the behavior with other similar functions. Change the behavior of `studentTTest` to return NaN instead of throwing an exception because the previous behavior was inconvenient. This closes [#41176](https://github.com/ClickHouse/ClickHouse/issues/41176) This closes [#42162](https://github.com/ClickHouse/ClickHouse/issues/42162). [#46141](https://github.com/ClickHouse/ClickHouse/pull/46141) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* More convenient usage of big integers and ORDER BY WITH FILL. Allow using plain integers for start and end points in WITH FILL when ORDER BY big (128-bit and 256-bit) integers. Fix the wrong result for big integers with negative start or end points. This closes [#16733](https://github.com/ClickHouse/ClickHouse/issues/16733). [#46152](https://github.com/ClickHouse/ClickHouse/pull/46152) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add `parts`, `active_parts` and `total_marks` columns to `system.tables` on [issue](https://github.com/ClickHouse/ClickHouse/issues/44336). [#46161](https://github.com/ClickHouse/ClickHouse/pull/46161) ([attack204](https://github.com/attack204)).
+* Functions "multi[Fuzzy]Match(Any|AnyIndex|AllIndices}" now reject regexes which will likely evaluate very slowly in vectorscan. [#46167](https://github.com/ClickHouse/ClickHouse/pull/46167) ([Robert Schulze](https://github.com/rschu1ze)).
+* When `insert_null_as_default` is enabled and column doesn't have defined default value, the default of column type will be used. Also this PR fixes using default values on nulls in case of LowCardinality columns. [#46171](https://github.com/ClickHouse/ClickHouse/pull/46171) ([Kruglov Pavel](https://github.com/Avogar)).
+* Prefer explicitly defined access keys for S3 clients. If `use_environment_credentials` is set to `true`, and the user has provided the access key through query or config, they will be used instead of the ones from the environment variable. [#46191](https://github.com/ClickHouse/ClickHouse/pull/46191) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add an alias "DATE_FORMAT()" for function "formatDateTime()" to improve compatibility with MySQL's SQL dialect, extend function `formatDateTime` with substitutions "a", "b", "c", "h", "i", "k", "l" "r", "s", "W". ### Documentation entry for user-facing changes User-readable short description: `DATE_FORMAT` is an alias of `formatDateTime`. Formats a Time according to the given Format string. Format is a constant expression, so you cannot have multiple formats for a single result column. (Provide link to [formatDateTime](https://clickhouse.com/docs/en/sql-reference/functions/date-time-functions/#formatdatetime)). [#46302](https://github.com/ClickHouse/ClickHouse/pull/46302) ([Jake Bamrah](https://github.com/JakeBamrah)).
+* Add `ProfileEvents` and `CurrentMetrics` about the callback tasks for parallel replicas (`s3Cluster` and `MergeTree` tables). [#46313](https://github.com/ClickHouse/ClickHouse/pull/46313) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add support for `DELETE` and `UPDATE` for tables using `KeeperMap` storage engine. [#46330](https://github.com/ClickHouse/ClickHouse/pull/46330) ([Antonio Andelic](https://github.com/antonio2368)).

+* Exclude the internal database used for temporary/external tables from the calculation of asynchronous metric "NumberOfDatabases". This makes the behavior consistent with system table "system.databases". [#46435](https://github.com/ClickHouse/ClickHouse/pull/46435) ([Robert Schulze](https://github.com/rschu1ze)).
+* Added `last_exception_time` column into distribution_queue table. [#46564](https://github.com/ClickHouse/ClickHouse/pull/46564) ([Aleksandr](https://github.com/AVMusorin)).
+* Support for IN clause with parameter in parameterized views. [#46583](https://github.com/ClickHouse/ClickHouse/pull/46583) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Do not load named collections on server startup (load them on first access instead). [#46607](https://github.com/ClickHouse/ClickHouse/pull/46607) ([Kseniia Sumarokova](https://github.com/kssenii)).
+

+* Add an option for `clickhouse-watchdog` to restart the child process. This does not make a lot of use. [#46312](https://github.com/ClickHouse/ClickHouse/pull/46312) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* If the environment variable `CLICKHOUSE_DOCKER_RESTART_ON_EXIT` is set to 1, the Docker container will run `clickhouse-server` as a child instead of the first process, and restart it when it exited. [#46391](https://github.com/ClickHouse/ClickHouse/pull/46391) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Fix Systemd service file. [#46461](https://github.com/ClickHouse/ClickHouse/pull/46461) ([SuperDJY](https://github.com/cmsxbc)).

+* Fixes to correctly use `odbc_bridge_use_connection_pooling` setting. [#45591](https://github.com/ClickHouse/ClickHouse/pull/45591) ([Bharat Nallan](https://github.com/bharatnc)).
+* When the callback in the cache is called, it is possible that this cache is destructed. To keep it safe, we capture members by value. It's also safe for task schedule because it will be deactivated before storage is destroyed. Resolve [#45548](https://github.com/ClickHouse/ClickHouse/issues/45548). [#45601](https://github.com/ClickHouse/ClickHouse/pull/45601) ([Han Fei](https://github.com/hanfei1991)).

+* When use experimental analyzer, queries like `SELECT number FROM numbers(100) LIMIT 10 OFFSET 10;` get wrong results (empty result for this sql). That is caused by an unnecessary offset step added by planner. [#45822](https://github.com/ClickHouse/ClickHouse/pull/45822) ([刘陶峰](https://github.com/taofengliu)).
+* Backward compatibility - allow implicit narrowing conversion from UInt64 to IPv4 - required for "INSERT ... VALUES ..." expression. [#45865](https://github.com/ClickHouse/ClickHouse/pull/45865) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).

+* Add the `query_kind` column to the `system.processes` table and the `SHOW PROCESSLIST` query. Remove duplicate code. It fixes a bug: the global configuration parameter `max_concurrent_select_queries` was not respected to queries with `INTERSECT` or `EXCEPT` chains. [#45872](https://github.com/ClickHouse/ClickHouse/pull/45872) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Fix crash in a function `stochasticLinearRegression`. Found by WingFuzz. [#45985](https://github.com/ClickHouse/ClickHouse/pull/45985) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

+* Follow-up fix for Replace domain IP types (IPv4, IPv6) with native https://github.com/ClickHouse/ClickHouse/pull/43221. [#46087](https://github.com/ClickHouse/ClickHouse/pull/46087) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Fix environment variable substitution in the configuration when a parameter already has a value. This closes [#46131](https://github.com/ClickHouse/ClickHouse/issues/46131). This closes [#9547](https://github.com/ClickHouse/ClickHouse/issues/9547). [#46144](https://github.com/ClickHouse/ClickHouse/pull/46144) ([pufit](https://github.com/pufit)).
+* Fix incorrect predicate push down with grouping sets. Closes [#45947](https://github.com/ClickHouse/ClickHouse/issues/45947). [#46151](https://github.com/ClickHouse/ClickHouse/pull/46151) ([flynn](https://github.com/ucasfl)).
+* Fix possible pipeline stuck error on `fulls_sorting_join` with constant keys. [#46175](https://github.com/ClickHouse/ClickHouse/pull/46175) ([Vladimir C](https://github.com/vdimir)).
+* Never rewrite tuple functions as literals during formatting to avoid incorrect results. [#46232](https://github.com/ClickHouse/ClickHouse/pull/46232) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
+* Fix possible out of bounds error while reading LowCardinality(Nullable) in Arrow format. [#46270](https://github.com/ClickHouse/ClickHouse/pull/46270) ([Kruglov Pavel](https://github.com/Avogar)).
+* Fix `SYSTEM UNFREEZE` queries failing with the exception `CANNOT_PARSE_INPUT_ASSERTION_FAILED`. [#46325](https://github.com/ClickHouse/ClickHouse/pull/46325) ([Aleksei Filatov](https://github.com/aalexfvk)).
+* Fix possible crash which can be caused by an integer overflow while deserializing aggregating state of a function that stores HashTable. [#46349](https://github.com/ClickHouse/ClickHouse/pull/46349) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Fix possible `LOGICAL_ERROR` in asynchronous inserts with invalid data sent in format `VALUES`. [#46350](https://github.com/ClickHouse/ClickHouse/pull/46350) ([Anton Popov](https://github.com/CurtizJ)).
+* Fixed a LOGICAL_ERROR on an attempt to execute `ALTER ... MOVE PART ... TO TABLE`. This type of query was never actually supported. [#46359](https://github.com/ClickHouse/ClickHouse/pull/46359) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Fix s3Cluster schema inference in parallel distributed insert select when `parallel_distributed_insert_select` is enabled. [#46381](https://github.com/ClickHouse/ClickHouse/pull/46381) ([Kruglov Pavel](https://github.com/Avogar)).
+* Fix queries like `ALTER TABLE ... UPDATE nested.arr1 = nested.arr2 ...`, where `arr1` and `arr2` are fields of the same `Nested` column. [#46387](https://github.com/ClickHouse/ClickHouse/pull/46387) ([Anton Popov](https://github.com/CurtizJ)).
+* Scheduler may fail to schedule a task. If it happens, the whole MulityPartUpload should be aborted and `UploadHelper` must wait for already scheduled tasks. [#46451](https://github.com/ClickHouse/ClickHouse/pull/46451) ([Dmitry Novik](https://github.com/novikd)).
+* Fix PREWHERE for Merge with different default types (fixes some `NOT_FOUND_COLUMN_IN_BLOCK` when the default type for the column differs, also allow `PREWHERE` when the type of column is the same across tables, and prohibit it, only if it differs). [#46454](https://github.com/ClickHouse/ClickHouse/pull/46454) ([Azat Khuzhin](https://github.com/azat)).
+* Fix a crash that could happen when constant values are used in `ORDER BY`. Fixes [#46466](https://github.com/ClickHouse/ClickHouse/issues/46466). [#46493](https://github.com/ClickHouse/ClickHouse/pull/46493) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Do not throw exception if `disk` setting was specified on query level, but `storage_policy` was specified in config merge tree settings section. `disk` will override setting from config. [#46533](https://github.com/ClickHouse/ClickHouse/pull/46533) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Fix an invalid processing of constant `LowCardinality` argument in function `arrayMap`. This bug could lead to a segfault in release, and logical error `Bad cast` in debug build. [#46569](https://github.com/ClickHouse/ClickHouse/pull/46569) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* fixes [#46557](https://github.com/ClickHouse/ClickHouse/issues/46557). [#46611](https://github.com/ClickHouse/ClickHouse/pull/46611) ([Alexander Gololobov](https://github.com/davenger)).
+* Fix endless restarts of clickhouse-server systemd unit if server cannot start within 1m30sec (Disable timeout logic for starting clickhouse-server from systemd service). [#46613](https://github.com/ClickHouse/ClickHouse/pull/46613) ([Azat Khuzhin](https://github.com/azat)).
+* Allocated during asynchronous inserts memory buffers were deallocated in the global context and MemoryTracker counters for corresponding user and query were not updated correctly. That led to false positive OOM exceptions. [#46622](https://github.com/ClickHouse/ClickHouse/pull/46622) ([Dmitry Novik](https://github.com/novikd)).
+* Updated to not clear on_expression from table_join as its used by future analyze runs resolves [#45185](https://github.com/ClickHouse/ClickHouse/issues/45185). [#46487](https://github.com/ClickHouse/ClickHouse/pull/46487) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).

+### ClickHouse release v22.11.6.44-stable (73ddf91298f) FIXME as compared to v22.11.5.15-stable (d763e5a9239)
+
+#### Performance Improvement
+* Backported in [#45703](https://github.com/ClickHouse/ClickHouse/issues/45703): Fixed performance of short `SELECT` queries that read from tables with large number of`Array`/`Map`/`Nested` columns. [#45630](https://github.com/ClickHouse/ClickHouse/pull/45630) ([Anton Popov](https://github.com/CurtizJ)).
+* Backported in [#46376](https://github.com/ClickHouse/ClickHouse/issues/46376): Fix too big memory usage for vertical merges on non-remote disk. Respect `max_insert_delayed_streams_for_parallel_write` for the remote disk. [#46275](https://github.com/ClickHouse/ClickHouse/pull/46275) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+
+#### Build/Testing/Packaging Improvement
+* Backported in [#45977](https://github.com/ClickHouse/ClickHouse/issues/45977): Fix zookeeper downloading, update the version, and optimize the image size. [#44853](https://github.com/ClickHouse/ClickHouse/pull/44853) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Backported in [#46114](https://github.com/ClickHouse/ClickHouse/issues/46114): Remove the dependency on the `adduser` tool from the packages, because we don't use it. This fixes [#44934](https://github.com/ClickHouse/ClickHouse/issues/44934). [#45011](https://github.com/ClickHouse/ClickHouse/pull/45011) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Backported in [#46483](https://github.com/ClickHouse/ClickHouse/issues/46483): Get rid of unnecessary build for standalone clickhouse-keeper. [#46367](https://github.com/ClickHouse/ClickHouse/pull/46367) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Backported in [#46507](https://github.com/ClickHouse/ClickHouse/issues/46507): Some time ago the ccache compression was changed to `zst`, but `gz` archives are downloaded by default. It fixes it by prioritizing zst archive. [#46490](https://github.com/ClickHouse/ClickHouse/pull/46490) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+
+#### Bug Fix (user-visible misbehavior in official stable or prestable release)
+
+* Backported in [#45903](https://github.com/ClickHouse/ClickHouse/issues/45903): Fixed bug with non-parsable default value for EPHEMERAL column in table metadata. [#44026](https://github.com/ClickHouse/ClickHouse/pull/44026) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Backported in [#46239](https://github.com/ClickHouse/ClickHouse/issues/46239): A couple of seg faults have been reported around `c-ares`. All of the recent stack traces observed fail on inserting into `std::unodered_set<>`. I believe I have found the root cause of this, it seems to be unprocessed queries. Prior to this PR, CH calls `poll` to wait on the file descriptors in the `c-ares` channel. According to the [poll docs](https://man7.org/linux/man-pages/man2/poll.2.html), a negative return value means an error has ocurred. Because of this, we would abort the execution and return failure. The problem is that `poll` will also return a negative value if a system interrupt occurs. A system interrupt does not mean the processing has failed or ended, but we would abort it anyways because we were checking for negative values. Once the execution is aborted, the whole stack is destroyed, which includes the `std::unordered_set<std::string>` passed to the `void *` parameter of the c-ares callback. Once c-ares completed the request, the callback would be invoked and would access an invalid memory address causing a segfault. [#45629](https://github.com/ClickHouse/ClickHouse/pull/45629) ([Arthur Passos](https://github.com/arthurpassos)).
+* Backported in [#46216](https://github.com/ClickHouse/ClickHouse/issues/46216): Fix reading of non existing nested columns with multiple level in compact parts. [#46045](https://github.com/ClickHouse/ClickHouse/pull/46045) ([Azat Khuzhin](https://github.com/azat)).
+* Backported in [#46444](https://github.com/ClickHouse/ClickHouse/issues/46444): Fix possible `LOGICAL_ERROR` in asynchronous inserts with invalid data sent in format `VALUES`. [#46350](https://github.com/ClickHouse/ClickHouse/pull/46350) ([Anton Popov](https://github.com/CurtizJ)).
+* Backported in [#46676](https://github.com/ClickHouse/ClickHouse/issues/46676): Fix an invalid processing of constant `LowCardinality` argument in function `arrayMap`. This bug could lead to a segfault in release, and logical error `Bad cast` in debug build. [#46569](https://github.com/ClickHouse/ClickHouse/pull/46569) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### NOT FOR CHANGELOG / INSIGNIFICANT
+
+* Another attempt to fix automerge, or at least to have debug footprint [#45476](https://github.com/ClickHouse/ClickHouse/pull/45476) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Add check for running workflows to merge_pr.py [#45803](https://github.com/ClickHouse/ClickHouse/pull/45803) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Get rid of progress timestamps in release publishing [#45818](https://github.com/ClickHouse/ClickHouse/pull/45818) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Add necessary dependency for sanitizers [#45959](https://github.com/ClickHouse/ClickHouse/pull/45959) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Add helping logging to auto-merge script [#46080](https://github.com/ClickHouse/ClickHouse/pull/46080) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Fix write buffer destruction order for vertical merge. [#46205](https://github.com/ClickHouse/ClickHouse/pull/46205) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Get rid of legacy DocsReleaseChecks [#46665](https://github.com/ClickHouse/ClickHouse/pull/46665) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).

+### ClickHouse release v23.2.1.2537-stable (52bf836e03a) FIXME as compared to v23.1.1.3077-stable (dcaac477025)
+
+#### Backward Incompatible Change
+* Extend function "toDayOfWeek()" (alias: "DAYOFWEEK") with a mode argument that encodes whether the week starts on Monday or Sunday and whether counting starts at 0 or 1. For consistency with other date time functions, the mode argument was inserted between the time and the time zone arguments. This breaks existing usage of the (previously undocumented) 2-argument syntax "toDayOfWeek(time, time_zone)". A fix is to rewrite the function into "toDayOfWeek(time, 0, time_zone)". [#45233](https://github.com/ClickHouse/ClickHouse/pull/45233) ([Robert Schulze](https://github.com/rschu1ze)).
+* Rename setting `max_query_cache_size` to `filesystem_cache_max_download_size`. [#45614](https://github.com/ClickHouse/ClickHouse/pull/45614) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Fix applying settings for FORMAT on the client. [#46003](https://github.com/ClickHouse/ClickHouse/pull/46003) ([Azat Khuzhin](https://github.com/azat)).
+* Default user will not have permissions for access type `SHOW NAMED COLLECTION` by default (e.g. by default, default user will not longer be able to do grant ALL to other users as it was before, therefore this PR is backward incompatible). [#46010](https://github.com/ClickHouse/ClickHouse/pull/46010) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Remove support for setting `materialized_postgresql_allow_automatic_update` (which was by default turned off). Fix integration tests. [#46106](https://github.com/ClickHouse/ClickHouse/pull/46106) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Slightly improve performance of `countDigits` on realistic datasets. This closed [#44518](https://github.com/ClickHouse/ClickHouse/issues/44518). In previous versions, `countDigits(0)` returned `0`; now it returns `1`, which is more correct, and follows the existing documentation. [#46187](https://github.com/ClickHouse/ClickHouse/pull/46187) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Expose ProfileEvents counters in system.part_log. [#38614](https://github.com/ClickHouse/ClickHouse/pull/38614) ([Bharat Nallan](https://github.com/bharatnc)).
+* Enrichment of the existing ReplacingMergeTree engine to allow duplicates insertion. It leverages the power of both ReplacingMergeTree and CollapsingMergeTree in one mergeTree engine. Deleted data are not returned when queried, but not removed from disk neither. [#41005](https://github.com/ClickHouse/ClickHouse/pull/41005) ([youennL-cs](https://github.com/youennL-cs)).
+* Add `generateULID()` function. Closes [#36536](https://github.com/ClickHouse/ClickHouse/issues/36536). [#44662](https://github.com/ClickHouse/ClickHouse/pull/44662) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Add `corrMatrix` Aggregatefunction, calculating each two columns. In addition, since Aggregatefunctions `covarSamp` and `covarPop` are similar to `corr`, I add `covarSampMatrix`, `covarPopMatrix` by the way. @alexey-milovidov closes [#44587](https://github.com/ClickHouse/ClickHouse/issues/44587). [#44680](https://github.com/ClickHouse/ClickHouse/pull/44680) ([FFFFFFFHHHHHHH](https://github.com/FFFFFFFHHHHHHH)).
+* Rewrite aggregate functions with if expression as argument when logically equivalent. For example, avg(if(cond, col, null)) can be rewritten to avgIf(cond, col). It is helpful in performance. [#44730](https://github.com/ClickHouse/ClickHouse/pull/44730) ([李扬](https://github.com/taiyang-li)).
+* Introduce arrayShuffle function for random array permutations. [#45271](https://github.com/ClickHouse/ClickHouse/pull/45271) ([Joanna Hulboj](https://github.com/jh0x)).
+* Support types FIXED_SIZE_BINARY type in Arrow, FIXED_LENGTH_BYTE_ARRAY in Parquet and match them to FixedString. Add settings `output_format_parquet_fixed_string_as_fixed_byte_array/output_format_arrow_fixed_string_as_fixed_byte_array` to control default output type for FixedString. Closes [#45326](https://github.com/ClickHouse/ClickHouse/issues/45326). [#45340](https://github.com/ClickHouse/ClickHouse/pull/45340) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add `StorageIceberg` and table function `iceberg` to access iceberg table store on S3. [#45384](https://github.com/ClickHouse/ClickHouse/pull/45384) ([flynn](https://github.com/ucasfl)).
+* Add a new column `last_exception_time` to system.replication_queue. [#45457](https://github.com/ClickHouse/ClickHouse/pull/45457) ([Frank Chen](https://github.com/FrankChen021)).
+* Add two new functions which allow for user-defined keys/seeds with SipHash{64,128}. [#45513](https://github.com/ClickHouse/ClickHouse/pull/45513) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
+* Allow a three-argument version for table function `format`. close [#45808](https://github.com/ClickHouse/ClickHouse/issues/45808). [#45873](https://github.com/ClickHouse/ClickHouse/pull/45873) ([FFFFFFFHHHHHHH](https://github.com/FFFFFFFHHHHHHH)).
+* add joda format support for 'x','w','S'.Refer to https://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html. [#46073](https://github.com/ClickHouse/ClickHouse/pull/46073) ([zk_kiger](https://github.com/zk-kiger)).
+* ... Support window function `ntile`. ``` insert into test_data values(1,2), (1,3), (1,4), (2,5),(2,6); select a, b, ntile(2) over (partition by a order by b rows between unbounded preceding and unbounded following ) from test_data;. [#46256](https://github.com/ClickHouse/ClickHouse/pull/46256) ([lgbo](https://github.com/lgbo-ustc)).
+* Added arrayPartialSort and arrayPartialReverseSort functions. [#46296](https://github.com/ClickHouse/ClickHouse/pull/46296) ([Joanna Hulboj](https://github.com/jh0x)).
+* The new http parameter `client_protocol_version` allows setting a client protocol version for HTTP responses using the Native format. [#40397](https://github.com/ClickHouse/ClickHouse/issues/40397). [#46360](https://github.com/ClickHouse/ClickHouse/pull/46360) ([Geoff Genz](https://github.com/genzgd)).
+* Add new function regexpExtract, like spark function REGEXP_EXTRACT. [#46469](https://github.com/ClickHouse/ClickHouse/pull/46469) ([李扬](https://github.com/taiyang-li)).
+* Author: [taiyang-li](https://github.com/taiyang-li) Add new function regexpExtract, like spark function REGEXP_EXTRACT. [#46529](https://github.com/ClickHouse/ClickHouse/pull/46529) ([Alexander Gololobov](https://github.com/davenger)).
+* Add new function JSONArrayLength, which returns the number of elements in the outermost JSON array. The function returns NULL if input JSON string is invalid. [#46631](https://github.com/ClickHouse/ClickHouse/pull/46631) ([李扬](https://github.com/taiyang-li)).
+
+#### Performance Improvement
+* Improve lower/upper function performance with avx512 instructions. [#37894](https://github.com/ClickHouse/ClickHouse/pull/37894) ([yaqi-zhao](https://github.com/yaqi-zhao)).
+* Add new `local_filesystem_read_method` method `io_uring` based on the asynchronous Linux [io_uring](https://kernel.dk/io_uring.pdf) subsystem, improving read performance almost universally compared to the default `pread` method. [#38456](https://github.com/ClickHouse/ClickHouse/pull/38456) ([Saulius Valatka](https://github.com/sauliusvl)).
+* Remove the limitation that on systems with >=32 cores and SMT disabled ClickHouse uses only half of the cores. [#44973](https://github.com/ClickHouse/ClickHouse/pull/44973) ([Robert Schulze](https://github.com/rschu1ze)).
+* Improve performance of function multiIf by columnar executing, speed up by 2.3x. [#45296](https://github.com/ClickHouse/ClickHouse/pull/45296) ([李扬](https://github.com/taiyang-li)).
+* An option added to aggregate partitions independently if table partition key and group by key are compatible. Controlled by the setting `allow_aggregate_partitions_independently`. Disabled by default because of limited applicability (please refer to the docs). [#45364](https://github.com/ClickHouse/ClickHouse/pull/45364) ([Nikita Taranov](https://github.com/nickitat)).
+* Add fastpath for function position when needle is empty. [#45382](https://github.com/ClickHouse/ClickHouse/pull/45382) ([李扬](https://github.com/taiyang-li)).
+* Enable `query_plan_remove_redundant_sorting` optimization by default. Optimization implemented in [#45420](https://github.com/ClickHouse/ClickHouse/issues/45420). [#45567](https://github.com/ClickHouse/ClickHouse/pull/45567) ([Igor Nikonov](https://github.com/devcrafter)).
+* Increased HTTP Transfer Encoding chunk size to improve performance of large queries using the HTTP interface. [#45593](https://github.com/ClickHouse/ClickHouse/pull/45593) ([Geoff Genz](https://github.com/genzgd)).
+* Fixed performance of short `SELECT` queries that read from tables with large number of`Array`/`Map`/`Nested` columns. [#45630](https://github.com/ClickHouse/ClickHouse/pull/45630) ([Anton Popov](https://github.com/CurtizJ)).
+* Allow using Vertical merge algorithm with parts in Compact format. This will allow ClickHouse server to use much less memory for background operations. This closes [#46084](https://github.com/ClickHouse/ClickHouse/issues/46084). [#45681](https://github.com/ClickHouse/ClickHouse/pull/45681) ([Anton Popov](https://github.com/CurtizJ)).
+* Optimize Parquet reader by using batch reader. [#45878](https://github.com/ClickHouse/ClickHouse/pull/45878) ([LiuNeng](https://github.com/liuneng1994)).
+* Improve performance of ColumnArray::filter for big int and decimal. [#45949](https://github.com/ClickHouse/ClickHouse/pull/45949) ([李扬](https://github.com/taiyang-li)).
+* This change could effectively reduce the overhead of obtaining the filter from ColumnNullable(UInt8) and improve the overall query performance. To evaluate the impact of this change, we adopted TPC-H benchmark but revised the column types from non-nullable to nullable, and we measured the QPS of its queries as the performance indicator. [#45962](https://github.com/ClickHouse/ClickHouse/pull/45962) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Make the `_part` and `_partition_id` virtual column be `LowCardinality(String)` type. Closes [#45964](https://github.com/ClickHouse/ClickHouse/issues/45964). [#45975](https://github.com/ClickHouse/ClickHouse/pull/45975) ([flynn](https://github.com/ucasfl)).
+* Improve the performance of Decimal conversion when the scale does not change. [#46095](https://github.com/ClickHouse/ClickHouse/pull/46095) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The introduced logic works if PREWHERE condition is a conjunction of multiple conditions (cond1 AND cond2 AND ... ). It groups those conditions that require reading the same columns into steps. After each step the corresponding part of the full condition is computed and the result rows might be filtered. This allows to read fewer rows in the next steps thus saving IO bandwidth and doing less computation. This logic is disabled by default for now. It will be enabled by default in one of the future releases once it is known to not have any regressions, so it is highly encouraged to be used for testing. It can be controlled by 2 settings: "enable_multiple_prewhere_read_steps" and "move_all_conditions_to_prewhere". [#46140](https://github.com/ClickHouse/ClickHouse/pull/46140) ([Alexander Gololobov](https://github.com/davenger)).
+* Allow to increase prefetching for read data. [#46168](https://github.com/ClickHouse/ClickHouse/pull/46168) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Rewrite arrayExists(x -> x = 1, arr) -> has(arr, 1), which improve performance by 1.34x. [#46188](https://github.com/ClickHouse/ClickHouse/pull/46188) ([李扬](https://github.com/taiyang-li)).
+* Fix too big memory usage for vertical merges on non-remote disk. Respect `max_insert_delayed_streams_for_parallel_write` for the remote disk. [#46275](https://github.com/ClickHouse/ClickHouse/pull/46275) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Update zstd to v1.5.4. It has some minor improvements in performance and compression ratio. If you run replicas with different versions of ClickHouse you may see reasonable error messages `Data after merge/mutation is not byte-identical to data on another replicas.` with explanation. These messages are Ok and you should not worry. [#46280](https://github.com/ClickHouse/ClickHouse/pull/46280) ([Raúl Marín](https://github.com/Algunenano)).
+* Allow using Vertical merge algorithm with parts in Compact format. This will allow ClickHouse server to use much less memory for background operations. This closes [#46084](https://github.com/ClickHouse/ClickHouse/issues/46084). [#46282](https://github.com/ClickHouse/ClickHouse/pull/46282) ([Anton Popov](https://github.com/CurtizJ)).
+* Fix performance degradation caused by [#39737](https://github.com/ClickHouse/ClickHouse/issues/39737). [#46309](https://github.com/ClickHouse/ClickHouse/pull/46309) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The `replicas_status` handle will answer quickly even in case of a large replication queue. [#46310](https://github.com/ClickHouse/ClickHouse/pull/46310) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### Improvement
+* Add avx512 support for Aggregate Sum, function unary arithmetic, function comparison. [#37870](https://github.com/ClickHouse/ClickHouse/pull/37870) ([zhao zhou](https://github.com/zzachimed)).
+* close issue: [#38893](https://github.com/ClickHouse/ClickHouse/issues/38893). [#38950](https://github.com/ClickHouse/ClickHouse/pull/38950) ([hexiaoting](https://github.com/hexiaoting)).
+* Migration from other databases and updates/deletes are mimicked by Collapsing/Replacing. Want to use the same SELECT queries without adding FINAL to all the existing queries. [#40945](https://github.com/ClickHouse/ClickHouse/pull/40945) ([Arthur Passos](https://github.com/arthurpassos)).
+* Allow configuring storage as `SETTINGS disk='<disk_name>'` (instead of `storage_policy`) and with explicit disk creation `SETTINGS disk=disk(type=s3, ...)`. [#41976](https://github.com/ClickHouse/ClickHouse/pull/41976) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add new metrics for backups: num_processed_files and processed_files_size described actual number of processed files. [#42244](https://github.com/ClickHouse/ClickHouse/pull/42244) ([Aleksandr](https://github.com/AVMusorin)).
+* Added retries on interserver DNS errors. [#43179](https://github.com/ClickHouse/ClickHouse/pull/43179) ([Anton Kozlov](https://github.com/tonickkozlov)).
+* Rewrote the code around marks distribution and the overall coordination of the reading in order to achieve the maximum performance improvement. This closes [#34527](https://github.com/ClickHouse/ClickHouse/issues/34527). [#43772](https://github.com/ClickHouse/ClickHouse/pull/43772) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Remove redundant DISTINCT clauses in query (subqueries). Implemented on top of query plan. It does similar optimization as `optimize_duplicate_order_by_and_distinct` regarding DISTINCT clauses. Can be enabled via `query_plan_remove_redundant_distinct` setting. Related to [#42648](https://github.com/ClickHouse/ClickHouse/issues/42648). [#44176](https://github.com/ClickHouse/ClickHouse/pull/44176) ([Igor Nikonov](https://github.com/devcrafter)).
+* Keeper improvement: try preallocating space on the disk to avoid undefined out-of-space issues. Introduce setting `max_log_file_size` for the maximum size of Keeper's Raft log files. [#44370](https://github.com/ClickHouse/ClickHouse/pull/44370) ([Antonio Andelic](https://github.com/antonio2368)).

+* Rename setting `replication_alter_partitions_sync` to `alter_sync`. [#45659](https://github.com/ClickHouse/ClickHouse/pull/45659) ([Antonio Andelic](https://github.com/antonio2368)).
+* The `generateRandom` table function and the engine now support `LowCardinality` data types. This is useful for testing, for example you can write `INSERT INTO table SELECT * FROM generateRandom() LIMIT 1000`. This is needed to debug [#45590](https://github.com/ClickHouse/ClickHouse/issues/45590). [#45661](https://github.com/ClickHouse/ClickHouse/pull/45661) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

+* add **SYSTEM SYNC FILE CACHE** command. It will call sync syscall. It achieve [#8921](https://github.com/ClickHouse/ClickHouse/issues/8921). [#45685](https://github.com/ClickHouse/ClickHouse/pull/45685) ([DR](https://github.com/freedomDR)).
+* Add new S3 setting `allow_head_object_request`. This PR makes usage of `GetObjectAttributes` request instead of `HeadObject` introduced in https://github.com/ClickHouse/ClickHouse/pull/45288 optional (and disabled by default). [#45701](https://github.com/ClickHouse/ClickHouse/pull/45701) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Add ability to override connection settings based on connection names (that said that now you can forget about storing password for each connection, you can simply put everything into `~/.clickhouse-client/config.xml` and even use different history files for them, which can be also useful). [#45715](https://github.com/ClickHouse/ClickHouse/pull/45715) ([Azat Khuzhin](https://github.com/azat)).
+* Arrow format support duration type. Closes [#45669](https://github.com/ClickHouse/ClickHouse/issues/45669). [#45750](https://github.com/ClickHouse/ClickHouse/pull/45750) ([flynn](https://github.com/ucasfl)).

+* Improved how memory bound merging and aggregation in order on top query plan interact. Previously we fell back to explicit sorting for AIO in some cases when it wasn't actually needed. So it is a perf issue, not a correctness one. [#45892](https://github.com/ClickHouse/ClickHouse/pull/45892) ([Nikita Taranov](https://github.com/nickitat)).
+* Improve behaviour of conversion into Date for boundary value 65535 (2149-06-06). [#45914](https://github.com/ClickHouse/ClickHouse/pull/45914) ([Joanna Hulboj](https://github.com/jh0x)).

+* Add reference implementation for SipHash128. [#46065](https://github.com/ClickHouse/ClickHouse/pull/46065) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
+* Add new metric to record allocations times and bytes using mmap. [#46068](https://github.com/ClickHouse/ClickHouse/pull/46068) ([李扬](https://github.com/taiyang-li)).
+* Currently for functions like `leftPad`, `rightPad`, `leftPadUTF8`, `rightPadUTF8`, the second argument `length` must be UInt8|16|32|64|128|256. Which is too strict for clickhouse users, besides, it is not consistent with other similar functions like `arrayResize`, `substring` and so on. [#46103](https://github.com/ClickHouse/ClickHouse/pull/46103) ([李扬](https://github.com/taiyang-li)).
+* Update CapnProto to v0.10.3 to avoid CVE-2022-46149 ### Documentation entry for user-facing changes. [#46139](https://github.com/ClickHouse/ClickHouse/pull/46139) ([Mallik Hassan](https://github.com/SadiHassan)).
+* Fix assertion in the `welchTTest` function in debug build when the resulting statistics is NaN. Unified the behavior with other similar functions. Change the behavior of `studentTTest` to return NaN instead of throwing an exception because the previous behavior was inconvenient. This closes [#41176](https://github.com/ClickHouse/ClickHouse/issues/41176) This closes [#42162](https://github.com/ClickHouse/ClickHouse/issues/42162). [#46141](https://github.com/ClickHouse/ClickHouse/pull/46141) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* More convenient usage of big integers and ORDER BY WITH FILL. Allow using plain integers for start and end points in WITH FILL when ORDER BY big (128-bit and 256-bit) integers. Fix the wrong result for big integers with negative start or end points. This closes [#16733](https://github.com/ClickHouse/ClickHouse/issues/16733). [#46152](https://github.com/ClickHouse/ClickHouse/pull/46152) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add parts, active_parts and total_marks columns to system.tables on [issue](https://github.com/ClickHouse/ClickHouse/issues/44336). [#46161](https://github.com/ClickHouse/ClickHouse/pull/46161) ([attack204](https://github.com/attack204)).
+* Functions "multi[Fuzzy]Match(Any|AnyIndex|AllIndices}" now reject regexes which will likely evaluate very slowly in vectorscan. [#46167](https://github.com/ClickHouse/ClickHouse/pull/46167) ([Robert Schulze](https://github.com/rschu1ze)).
+* When `insert_null_as_default` is enabled and column doesn't have defined default value, the default of column type will be used. Also this PR fixes using default values on nulls in case of LowCardinality columns. [#46171](https://github.com/ClickHouse/ClickHouse/pull/46171) ([Kruglov Pavel](https://github.com/Avogar)).
+* Prefer explicitly defined access keys for S3 clients. If `use_environment_credentials` is set to `true`, and the user has provided the access key through query or config, they will be used instead of the ones from the environment variable. [#46191](https://github.com/ClickHouse/ClickHouse/pull/46191) ([Antonio Andelic](https://github.com/antonio2368)).
+* Concurrent merges are scheduled using round-robin by default to ensure fair and starvation-free operation. Previously in heavily overloaded shards, big merges could possibly be starved by smaller merges due to the use of strict priority scheduling. Added `background_merges_mutations_scheduling_policy` server config option to select scheduling algorithm (`round_robin` or `shortest_task_first`). [#46247](https://github.com/ClickHouse/ClickHouse/pull/46247) ([Sergei Trifonov](https://github.com/serxa)).
+* Extend setting `input_format_null_as_default` for more formats. Fix setting `input_format_defaults_for_omitted_fields` with Native and TSKV formats. [#46284](https://github.com/ClickHouse/ClickHouse/pull/46284) ([Kruglov Pavel](https://github.com/Avogar)).
+* - Add an alias "DATE_FORMAT()" for function "formatDateTime()" to improve compatibility with MySQL's SQL dialect, extend function`formatDateTime()` with substitutions "a", "b", "c", "h", "i", "k", "l" "r", "s", "W". ### Documentation entry for user-facing changes User-readable short description: `DATE_FORMAT` is an alias of `formatDateTime`. Formats a Time according to the given Format string. Format is a constant expression, so you cannot have multiple formats for a single result column. (Provide link to [formatDateTime](https://clickhouse.com/docs/en/sql-reference/functions/date-time-functions/#formatdatetime)). [#46302](https://github.com/ClickHouse/ClickHouse/pull/46302) ([Jake Bamrah](https://github.com/JakeBamrah)).
+* not for changelog - part of [#42648](https://github.com/ClickHouse/ClickHouse/issues/42648). [#46306](https://github.com/ClickHouse/ClickHouse/pull/46306) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).

+* Add `ProfileEvents` and `CurrentMetrics` about the callback tasks for parallel replicas (`s3Cluster` and `MergeTree` tables). [#46313](https://github.com/ClickHouse/ClickHouse/pull/46313) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add support for `DELETE` and `UPDATE` for tables using `KeeperMap` storage engine. [#46330](https://github.com/ClickHouse/ClickHouse/pull/46330) ([Antonio Andelic](https://github.com/antonio2368)).
+* Update unixodbc to v2.3.11 to mitigate CVE-2011-1145 ### Documentation entry for user-facing changes. [#46363](https://github.com/ClickHouse/ClickHouse/pull/46363) ([Mallik Hassan](https://github.com/SadiHassan)).
+* - Apply `ALTER TABLE table_name ON CLUSTER cluster MOVE PARTITION|PART partition_expr TO DISK|VOLUME 'disk_name'` to all replicas. Because `ALTER TABLE t MOVE` is not replicated. [#46402](https://github.com/ClickHouse/ClickHouse/pull/46402) ([lizhuoyu5](https://github.com/lzydmxy)).
+* Allow writing RENAME queries with query parameters. Resolves [#45778](https://github.com/ClickHouse/ClickHouse/issues/45778). [#46407](https://github.com/ClickHouse/ClickHouse/pull/46407) ([Nikolay Degterinsky](https://github.com/evillique)).

+* Exclude the internal database used for temporary/external tables from the calculation of asynchronous metric "NumberOfDatabases". This makes the behavior consistent with system table "system.databases". [#46435](https://github.com/ClickHouse/ClickHouse/pull/46435) ([Robert Schulze](https://github.com/rschu1ze)).
+* Added `last_exception_time` column into distribution_queue table. [#46564](https://github.com/ClickHouse/ClickHouse/pull/46564) ([Aleksandr](https://github.com/AVMusorin)).
+* Support for IN clause in parameterized views Implementation: * In case of parameterized views, the IN clause cannot be evaluated as constant expression during CREATE VIEW, added a check to ignore this step in case of parameterized view. * If parmeters are not in IN clause, we continue to evaluate it as constant expression. [#46583](https://github.com/ClickHouse/ClickHouse/pull/46583) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Do not load named collections on server startup (load them on first access instead). [#46607](https://github.com/ClickHouse/ClickHouse/pull/46607) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add separate access type `SHOW_NAMED_COLLECTIONS_SECRETS` to allow to see named collections and their keys, but making values hidden. Nevertheless, access type `SHOW NAMED COLLECTIONS` is still required. [#46667](https://github.com/ClickHouse/ClickHouse/pull/46667) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Hide arguments of custom disk merge tree setting. [#46670](https://github.com/ClickHouse/ClickHouse/pull/46670) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Ask for the password in clickhouse-client interactively in a case when the empty password is wrong. Closes [#46702](https://github.com/ClickHouse/ClickHouse/issues/46702). [#46730](https://github.com/ClickHouse/ClickHouse/pull/46730) ([Nikolay Degterinsky](https://github.com/evillique)).

+* Allow to fallback from asynchronous insert to synchronous in case of large amount of data (more than `async_insert_max_data_size` bytes in single insert). [#46753](https://github.com/ClickHouse/ClickHouse/pull/46753) ([Anton Popov](https://github.com/CurtizJ)).
+
+#### Bug Fix
+* Fix wiping sensitive info in logs. [#45603](https://github.com/ClickHouse/ClickHouse/pull/45603) ([Vitaly Baranov](https://github.com/vitlibar)).
+* There is a check in format "time_check() || ptr ? ptr->finished() : data->is_finished()". Operator "||" will be executed before operator "?", but expected that there should be separated time and ptr checks. Also it's unexpected to run "ptr->finished()" in case of nullptr, but with current expression it's possible. [#46054](https://github.com/ClickHouse/ClickHouse/pull/46054) ([Alexey Perevyshin](https://github.com/alexX512)).
+
+#### Build/Testing/Packaging Improvement
+* Allow to randomize merge tree settings in tests. [#38983](https://github.com/ClickHouse/ClickHouse/pull/38983) ([Anton Popov](https://github.com/CurtizJ)).

+* Remove excessive license notices from preciseExp10.cpp. [#46163](https://github.com/ClickHouse/ClickHouse/pull/46163) ([DimasKovas](https://github.com/DimasKovas)).
+* Add an option for `clickhouse-watchdog` to restart the child process. This does not make a lot of use. [#46312](https://github.com/ClickHouse/ClickHouse/pull/46312) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Get rid of unnecessary build for standalone clickhouse-keeper. [#46367](https://github.com/ClickHouse/ClickHouse/pull/46367) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* If the environment variable `CLICKHOUSE_DOCKER_RESTART_ON_EXIT` is set to 1, the Docker container will run `clickhouse-server` as a child instead of the first process, and restart it when it exited. [#46391](https://github.com/ClickHouse/ClickHouse/pull/46391) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* - Fix Systemd service file. [#46461](https://github.com/ClickHouse/ClickHouse/pull/46461) ([SuperDJY](https://github.com/cmsxbc)).
+* Some time ago the ccache compression was changed to `zst`, but `gz` archives are downloaded by default. It fixes it by prioritizing zst archive. [#46490](https://github.com/ClickHouse/ClickHouse/pull/46490) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Raised the minimum Clang version needed to build ClickHouse from 12 to 15. [#46710](https://github.com/ClickHouse/ClickHouse/pull/46710) ([Robert Schulze](https://github.com/rschu1ze)).
+
+#### Bug Fix (user-visible misbehavior in official stable or prestable release)
+
+* Flush data exactly by `rabbitmq_flush_interval_ms` or by `rabbitmq_max_block_size` in `StorageRabbitMQ`. Closes [#42389](https://github.com/ClickHouse/ClickHouse/issues/42389). Closes [#45160](https://github.com/ClickHouse/ClickHouse/issues/45160). [#44404](https://github.com/ClickHouse/ClickHouse/pull/44404) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* - Use PODArray to render in sparkBar function, so we can control the memory usage. Close [#44467](https://github.com/ClickHouse/ClickHouse/issues/44467). [#44489](https://github.com/ClickHouse/ClickHouse/pull/44489) ([Duc Canh Le](https://github.com/canhld94)).
+* Fix functions (quantilesExactExclusive, quantilesExactInclusive) return unsorted array element. [#45379](https://github.com/ClickHouse/ClickHouse/pull/45379) ([wujunfu](https://github.com/wujunfu)).
+* Fix uncaught exception in HTTPHandler when open telemetry is enabled. [#45456](https://github.com/ClickHouse/ClickHouse/pull/45456) ([Frank Chen](https://github.com/FrankChen021)).
+* Don't infer Dates from 8 digit numbers. It could lead to wrong data to be read. [#45581](https://github.com/ClickHouse/ClickHouse/pull/45581) ([Kruglov Pavel](https://github.com/Avogar)).
+* Fixes to correctly use `odbc_bridge_use_connection_pooling` setting. [#45591](https://github.com/ClickHouse/ClickHouse/pull/45591) ([Bharat Nallan](https://github.com/bharatnc)).
+* when the callback in the cache is called, it is possible that this cache is destructed. To keep it safe, we capture members by value. It's also safe for task schedule because it will be deactivated before storage is destroyed. Resolve [#45548](https://github.com/ClickHouse/ClickHouse/issues/45548). [#45601](https://github.com/ClickHouse/ClickHouse/pull/45601) ([Han Fei](https://github.com/hanfei1991)).
+* - Fix data corruption when codecs Delta or DoubleDelta are combined with codec Gorilla. [#45615](https://github.com/ClickHouse/ClickHouse/pull/45615) ([Robert Schulze](https://github.com/rschu1ze)).
+* Correctly check types when using N-gram bloom filter index to avoid invalid reads. [#45617](https://github.com/ClickHouse/ClickHouse/pull/45617) ([Antonio Andelic](https://github.com/antonio2368)).
+* A couple of seg faults have been reported around `c-ares`. All of the recent stack traces observed fail on inserting into `std::unodered_set<>`. I believe I have found the root cause of this, it seems to be unprocessed queries. Prior to this PR, CH calls `poll` to wait on the file descriptors in the `c-ares` channel. According to the [poll docs](https://man7.org/linux/man-pages/man2/poll.2.html), a negative return value means an error has ocurred. Because of this, we would abort the execution and return failure. The problem is that `poll` will also return a negative value if a system interrupt occurs. A system interrupt does not mean the processing has failed or ended, but we would abort it anyways because we were checking for negative values. Once the execution is aborted, the whole stack is destroyed, which includes the `std::unordered_set<std::string>` passed to the `void *` parameter of the c-ares callback. Once c-ares completed the request, the callback would be invoked and would access an invalid memory address causing a segfault.

 Tests should use (create, drop, etc) only tables in `test` database that is assumed to be created beforehand; also tests can use temporary tables.
 
+### Restricting test runs
+
+A test can have zero or more _test tags_ specifying restrictions for test runs.
+
+For `.sh` tests tags are written as a comment on the second line:
+
+```bash
+#!/usr/bin/env bash
+# Tags: no-fasttest
+```
+
+For `.sql` tests tags are placed in the first line as a SQL comment:
+
+```sql
+-- Tags: no-fasttest
+SELECT 1
+```
+
+|Tag name | What it does | Usage example |
+|---|---|---|
+| `disabled`|  Test is not run ||
+| `long` | Test's execution time is extended from 1 to 10 minutes ||
+| `deadlock` | Test is run in a loop for a long time ||
+| `race` | Same as `deadlock`. Prefer `deadlock` ||
+| `shard` | Server is required to listen to `127.0.0.*` ||
+| `distributed` | Same as `shard`. Prefer `shard` ||
+| `global` | Same as `shard`. Prefer `shard` ||
+| `zookeeper` | Test requires Zookeeper or ClickHouse Keeper to run | Test uses `ReplicatedMergeTree` |
+| `replica` | Same as `zookeeper`. Prefer `zookeeper` ||

+| `no-s3-storage` |||
+
+In addition to the above settings, you can use `USE_*` flags from `system.build_options` to define usage of particular ClickHouse features.
+For example, if your test uses a MySQL table, you should add a tag `use-mysql`.
+
 ### Choosing the Test Name
 
 The name of the test starts with a five-digit prefix followed by a descriptive name, such as `00422_hash_function_constexpr.sql`. To choose the prefix, find the largest prefix already present in the directory, and increment it by one. In the meantime, some other tests might be added with the same numeric prefix, but this is OK and does not lead to any problems, you don't have to change it later.
 
-Some tests are marked with `zookeeper`, `shard` or `long` in their names. `zookeeper` is for tests that are using ZooKeeper. `shard` is for tests that requires server to listen `127.0.0.*`; `distributed` or `global` have the same meaning. `long` is for tests that run slightly longer that one second. You can disable these groups of tests using `--no-zookeeper`, `--no-shard` and `--no-long` options, respectively. Make sure to add a proper prefix to your test name if it needs ZooKeeper or distributed queries.

 Sometimes you want to test that a server error occurs for an incorrect query. We support special annotations for this in SQL tests, in the following form:

-When you convert a value from one to another data type, you should remember that if you try to fit a value from a larger data type to a smaller one (for example Int64 to Int32), or convert from one data type to another (for example `String` to `Int`), you could have data loss.  Test beforehand.
+Be aware of potential data loss if values of a datatype are converted to a smaller datatype (for example from `Int64` to `Int32`) or between

 ### String
 
-Only string literals in single quotes are supported. The enclosed characters can be backslash-escaped. The following escape sequences have a corresponding special value: `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\a`, `\v`, `\xHH`. In all other cases, escape sequences in the format `\c`, where `c` is any character, are converted to `c`. It means that you can use the sequences `\'`and`\\`. The value will have the [String](../sql-reference/data-types/string.md) type.
