 # 2024 Changelog
 
+### <a id="245"></a> ClickHouse release 24.5, 2024-05-30
+
+#### Backward Incompatible Change
+* Renamed "inverted indexes" to "full-text indexes" which is a less technical / more user-friendly name. This also changes internal table metadata and breaks tables with existing (experimental) inverted indexes. Please make to drop such indexes before upgrade and re-create them after upgrade. [#62884](https://github.com/ClickHouse/ClickHouse/pull/62884) ([Robert Schulze](https://github.com/rschu1ze)).
+* Usage of functions `neighbor`, `runningAccumulate`, `runningDifferenceStartingWithFirstValue`, `runningDifference` deprecated (because it is error-prone). Proper window functions should be used instead. To enable them back, set `allow_deprecated_functions = 1` or set `compatibility = '24.4'` or lower. [#63132](https://github.com/ClickHouse/ClickHouse/pull/63132) ([Nikita Taranov](https://github.com/nickitat)).
+* Queries from `system.columns` will work faster if there is a large number of columns, but many databases or tables are not granted for `SHOW TABLES`. Note that in previous versions, if you grant `SHOW COLUMNS` to individual columns without granting `SHOW TABLES` to the corresponding tables, the `system.columns` table will show these columns, but in a new version, it will skip the table entirely. Remove trace log messages "Access granted" and "Access denied" that slowed down queries. [#63439](https://github.com/ClickHouse/ClickHouse/pull/63439) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Adds the `Form` format to read/write a single record in the `application/x-www-form-urlencoded` format. [#60199](https://github.com/ClickHouse/ClickHouse/pull/60199) ([Shaun Struwig](https://github.com/Blargian)).
+* Added possibility to compress in CROSS JOIN. [#60459](https://github.com/ClickHouse/ClickHouse/pull/60459) ([p1rattttt](https://github.com/p1rattttt)).
+* Added possibility to do `CROSS JOIN` in temporary files if the size exceeds limits. [#63432](https://github.com/ClickHouse/ClickHouse/pull/63432) ([p1rattttt](https://github.com/p1rattttt)).
+* Support join with inequal conditions which involve columns from both left and right table. e.g. `t1.y < t2.y`. To enable, `SET allow_experimental_join_condition = 1`. [#60920](https://github.com/ClickHouse/ClickHouse/pull/60920) ([lgbo](https://github.com/lgbo-ustc)).
+* Maps can now have `Float32`, `Float64`, `Array(T)`, `Map(K, V)` and `Tuple(T1, T2, ...)` as keys. Closes [#54537](https://github.com/ClickHouse/ClickHouse/issues/54537). [#59318](https://github.com/ClickHouse/ClickHouse/pull/59318) ([李扬](https://github.com/taiyang-li)).
+* Introduce bulk loading to `EmbeddedRocksDB` by creating and ingesting SST file instead of relying on rocksdb build-in memtable. This help to increase importing speed, especially for long-running insert query to StorageEmbeddedRocksDB tables. Also, introduce `EmbeddedRocksDB` table settings. [#59163](https://github.com/ClickHouse/ClickHouse/pull/59163) [#63324](https://github.com/ClickHouse/ClickHouse/pull/63324) ([Duc Canh Le](https://github.com/canhld94)).
+* User can now parse CRLF with TSV format using a setting `input_format_tsv_crlf_end_of_line`. Closes [#56257](https://github.com/ClickHouse/ClickHouse/issues/56257). [#59747](https://github.com/ClickHouse/ClickHouse/pull/59747) ([Shaun Struwig](https://github.com/Blargian)).
+* A new setting `input_format_force_null_for_omitted_fields` that forces NULL values for omitted fields. [#60887](https://github.com/ClickHouse/ClickHouse/pull/60887) ([Constantine Peresypkin](https://github.com/pkit)).
+* Earlier our S3 storage and s3 table function didn't support selecting from archive container files, such as tarballs, zip, 7z. Now they allow to iterate over files inside archives in S3. [#62259](https://github.com/ClickHouse/ClickHouse/pull/62259) ([Daniil Ivanik](https://github.com/divanik)).
+* Support for conditional function `clamp`. [#62377](https://github.com/ClickHouse/ClickHouse/pull/62377) ([skyoct](https://github.com/skyoct)).
+* Add `NPy` output format. [#62430](https://github.com/ClickHouse/ClickHouse/pull/62430) ([豪肥肥](https://github.com/HowePa)).
+* `Raw` format as a synonym for `TSVRaw`. [#63394](https://github.com/ClickHouse/ClickHouse/pull/63394) ([Unalian](https://github.com/Unalian)).
+* Added a new SQL function `generateUUIDv7` to generate version 7 UUIDs aka. timestamp-based UUIDs with random component. Also added a new function `UUIDToNum` to extract bytes from a UUID and a new function `UUIDv7ToDateTime` to extract timestamp component from a UUID version 7. [#62852](https://github.com/ClickHouse/ClickHouse/pull/62852) ([Alexey Petrunyaka](https://github.com/pet74alex)).
+* On Linux and MacOS, if the program has stdout redirected to a file with a compression extension, use the corresponding compression method instead of nothing (making it behave similarly to `INTO OUTFILE`). [#63662](https://github.com/ClickHouse/ClickHouse/pull/63662) ([v01dXYZ](https://github.com/v01dXYZ)).
+* Change warning on high number of attached tables to differentiate tables, views and dictionaries. [#64180](https://github.com/ClickHouse/ClickHouse/pull/64180) ([Francisco J. Jurado Moreno](https://github.com/Beetelbrox)).
+* Provide support for `azureBlobStorage` function in ClickHouse server to use Azure Workload identity to authenticate against Azure blob storage. If `use_workload_identity` parameter is set in config, [workload identity](https://github.com/Azure/azure-sdk-for-cpp/tree/main/sdk/identity/azure-identity#authenticate-azure-hosted-applications) is used for authentication. [#57881](https://github.com/ClickHouse/ClickHouse/pull/57881) ([Vinay Suryadevara](https://github.com/vinay92-ch)).
+* Add TTL information in the `system.parts_columns` table. [#63200](https://github.com/ClickHouse/ClickHouse/pull/63200) ([litlig](https://github.com/litlig)).
+
+#### Experimental Features
+* Implement `Dynamic` data type that allows to store values of any type inside it without knowing all of them in advance. `Dynamic` type is available under a setting `allow_experimental_dynamic_type`. Reference: [#54864](https://github.com/ClickHouse/ClickHouse/issues/54864). [#63058](https://github.com/ClickHouse/ClickHouse/pull/63058) ([Kruglov Pavel](https://github.com/Avogar)).
+* Allowed to create `MaterializedMySQL` database without connection to MySQL. [#63397](https://github.com/ClickHouse/ClickHouse/pull/63397) ([Kirill](https://github.com/kirillgarbar)).
+* Automatically mark a replica of Replicated database as lost and start recovery if some DDL task fails more than `max_retries_before_automatic_recovery` (100 by default) times in a row with the same error. Also, fixed a bug that could cause skipping DDL entries when an exception is thrown during an early stage of entry execution. [#63549](https://github.com/ClickHouse/ClickHouse/pull/63549) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Account failed files in `s3queue_tracked_file_ttl_sec` and `s3queue_traked_files_limit` for `StorageS3Queue`. [#63638](https://github.com/ClickHouse/ClickHouse/pull/63638) ([Kseniia Sumarokova](https://github.com/kssenii)).
+
+#### Performance Improvement
+* Less contention in filesystem cache (part 4). Allow to keep filesystem cache not filled to the limit by doing additional eviction in the background (controlled by `keep_free_space_size(elements)_ratio`). This allows to release pressure from space reservation for queries (on `tryReserve` method). Also this is done in a lock free way as much as possible, e.g. should not block normal cache usage. [#61250](https://github.com/ClickHouse/ClickHouse/pull/61250) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Skip merging of newly created projection blocks during `INSERT`-s. [#59405](https://github.com/ClickHouse/ClickHouse/pull/59405) ([Nikita Taranov](https://github.com/nickitat)).
+* Process string functions `...UTF8` 'asciily' if input strings are all ascii chars. Inspired by https://github.com/apache/doris/pull/29799. Overall speed up by 1.07x~1.62x. Notice that peak memory usage had been decreased in some cases. [#61632](https://github.com/ClickHouse/ClickHouse/pull/61632) ([李扬](https://github.com/taiyang-li)).
+* Improved performance of selection (`{}`) globs in StorageS3. [#62120](https://github.com/ClickHouse/ClickHouse/pull/62120) ([Andrey Zvonov](https://github.com/zvonand)).
+* HostResolver has each IP address several times. If remote host has several IPs and by some reason (firewall rules for example) access on some IPs allowed and on others forbidden, than only first record of forbidden IPs marked as failed, and in each try these IPs have a chance to be chosen (and failed again). Even if fix this, every 120 seconds DNS cache dropped, and IPs can be chosen again. [#62652](https://github.com/ClickHouse/ClickHouse/pull/62652) ([Anton Ivashkin](https://github.com/ianton-ru)).
+* Add a new configuration`prefer_merge_sort_block_bytes` to control the memory usage and speed up sorting 2 times when merging when there are many columns. [#62904](https://github.com/ClickHouse/ClickHouse/pull/62904) ([LiuNeng](https://github.com/liuneng1994)).
+* `clickhouse-local` will start faster. In previous versions, it was not deleting temporary directories by mistake. Now it will. This closes [#62941](https://github.com/ClickHouse/ClickHouse/issues/62941). [#63074](https://github.com/ClickHouse/ClickHouse/pull/63074) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Micro-optimizations for the new analyzer. [#63429](https://github.com/ClickHouse/ClickHouse/pull/63429) ([Raúl Marín](https://github.com/Algunenano)).
+* Index analysis will work if `DateTime` is compared to `DateTime64`. This closes [#63441](https://github.com/ClickHouse/ClickHouse/issues/63441). [#63443](https://github.com/ClickHouse/ClickHouse/pull/63443) [#63532](https://github.com/ClickHouse/ClickHouse/pull/63532) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Speed up indices of type `set` a little (around 1.5 times) by removing garbage. [#64098](https://github.com/ClickHouse/ClickHouse/pull/64098) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Remove copying data when writing to the filesystem cache. [#63401](https://github.com/ClickHouse/ClickHouse/pull/63401) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Now backups with azure blob storage will use multicopy. [#64116](https://github.com/ClickHouse/ClickHouse/pull/64116) ([alesapin](https://github.com/alesapin)).
+* Allow to use native copy for azure even with different containers. [#64154](https://github.com/ClickHouse/ClickHouse/pull/64154) ([alesapin](https://github.com/alesapin)).
+* Finally enable native copy for azure. [#64182](https://github.com/ClickHouse/ClickHouse/pull/64182) ([alesapin](https://github.com/alesapin)).
+
+#### Improvement
+* Allow using `clickhouse-local` and its shortcuts `clickhouse` and `ch` with a query or queries file as a positional argument. Examples: `ch "SELECT 1"`, `ch --param_test Hello "SELECT {test:String}"`, `ch query.sql`. This closes [#62361](https://github.com/ClickHouse/ClickHouse/issues/62361). [#63081](https://github.com/ClickHouse/ClickHouse/pull/63081) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Enable plain_rewritable metadata for local and Azure (azure_blob_storage) object storages. [#63365](https://github.com/ClickHouse/ClickHouse/pull/63365) ([Julia Kartseva](https://github.com/jkartseva)).
+* Support English-style Unicode quotes, e.g. “Hello”, ‘world’. This is questionable in general but helpful when you type your query in a word processor, such as Google Docs. This closes [#58634](https://github.com/ClickHouse/ClickHouse/issues/58634). [#63381](https://github.com/ClickHouse/ClickHouse/pull/63381) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow trailing commas in the columns list in the INSERT query. For example, `INSERT INTO test (a, b, c, ) VALUES ...`. [#63803](https://github.com/ClickHouse/ClickHouse/pull/63803) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Better exception messages for the `Regexp` format. [#63804](https://github.com/ClickHouse/ClickHouse/pull/63804) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow trailing commas in the `Values` format. For example, this query is allowed: `INSERT INTO test (a, b, c) VALUES (4, 5, 6,);`. [#63810](https://github.com/ClickHouse/ClickHouse/pull/63810) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Make rabbitmq nack broken messages. Closes [#45350](https://github.com/ClickHouse/ClickHouse/issues/45350). [#60312](https://github.com/ClickHouse/ClickHouse/pull/60312) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Fix a crash in asynchronous stack unwinding (such as when using the sampling query profiler) while interpreting debug info. This closes [#60460](https://github.com/ClickHouse/ClickHouse/issues/60460). [#60468](https://github.com/ClickHouse/ClickHouse/pull/60468) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Distinct messages for s3 error 'no key' for cases disk and storage. [#61108](https://github.com/ClickHouse/ClickHouse/pull/61108) ([Sema Checherinda](https://github.com/CheSema)).
+* The progress bar will work for trivial queries with LIMIT from `system.zeros`, `system.zeros_mt` (it already works for `system.numbers` and `system.numbers_mt`), and the `generateRandom` table function. As a bonus, if the total number of records is greater than the `max_rows_to_read` limit, it will throw an exception earlier. This closes [#58183](https://github.com/ClickHouse/ClickHouse/issues/58183). [#61823](https://github.com/ClickHouse/ClickHouse/pull/61823) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Support for "Merge Key" in YAML configurations (this is a weird feature of YAML, please never mind). [#62685](https://github.com/ClickHouse/ClickHouse/pull/62685) ([Azat Khuzhin](https://github.com/azat)).
+* Enhance error message when non-deterministic function is used with Replicated source. [#62896](https://github.com/ClickHouse/ClickHouse/pull/62896) ([Grégoire Pineau](https://github.com/lyrixx)).
+* Fix interserver secret for Distributed over Distributed from `remote`. [#63013](https://github.com/ClickHouse/ClickHouse/pull/63013) ([Azat Khuzhin](https://github.com/azat)).
+* Support `include_from` for YAML files. However, you should better use `config.d` [#63106](https://github.com/ClickHouse/ClickHouse/pull/63106) ([Eduard Karacharov](https://github.com/korowa)).
+* Keep previous data in terminal after picking from skim suggestions. [#63261](https://github.com/ClickHouse/ClickHouse/pull/63261) ([FlameFactory](https://github.com/FlameFactory)).
+* Width of fields (in Pretty formats or the `visibleWidth` function) now correctly ignores ANSI escape sequences. [#63270](https://github.com/ClickHouse/ClickHouse/pull/63270) ([Shaun Struwig](https://github.com/Blargian)).
+* Update the usage of error code `NUMBER_OF_ARGUMENTS_DOESNT_MATCH` by more accurate error codes when appropriate. [#63406](https://github.com/ClickHouse/ClickHouse/pull/63406) ([Yohann Jardin](https://github.com/yohannj)).
+* `os_user` and `client_hostname` are now correctly set up for queries for command line suggestions in clickhouse-client. This closes [#63430](https://github.com/ClickHouse/ClickHouse/issues/63430). [#63433](https://github.com/ClickHouse/ClickHouse/pull/63433) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Automatically correct `max_block_size` to the default value if it is zero. [#63587](https://github.com/ClickHouse/ClickHouse/pull/63587) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add a build_id ALIAS column to trace_log to facilitate auto renaming upon detecting binary changes. This is to address [#52086](https://github.com/ClickHouse/ClickHouse/issues/52086). [#63656](https://github.com/ClickHouse/ClickHouse/pull/63656) ([Zimu Li](https://github.com/woodlzm)).
+* Enable truncate operation for object storage disks. [#63693](https://github.com/ClickHouse/ClickHouse/pull/63693) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
+* The loading of the keywords list is now dependent on the server revision and will be disabled for the old versions of ClickHouse server. CC @azat. [#63786](https://github.com/ClickHouse/ClickHouse/pull/63786) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Clickhouse disks have to read server setting to obtain actual metadata format version. [#63831](https://github.com/ClickHouse/ClickHouse/pull/63831) ([Sema Checherinda](https://github.com/CheSema)).
+* Disable pretty format restrictions (`output_format_pretty_max_rows`/`output_format_pretty_max_value_width`) when stdout is not TTY. [#63942](https://github.com/ClickHouse/ClickHouse/pull/63942) ([Azat Khuzhin](https://github.com/azat)).
+* Exception handling now works when ClickHouse is used inside AWS Lambda. Author: [Alexey Coolnev](https://github.com/acoolnev). [#64014](https://github.com/ClickHouse/ClickHouse/pull/64014) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Throw `CANNOT_DECOMPRESS` instread of `CORRUPTED_DATA` on invalid compressed data passed via HTTP. [#64036](https://github.com/ClickHouse/ClickHouse/pull/64036) ([vdimir](https://github.com/vdimir)).
+* A tip for a single large number in Pretty formats now works for Nullable and LowCardinality. This closes [#61993](https://github.com/ClickHouse/ClickHouse/issues/61993). [#64084](https://github.com/ClickHouse/ClickHouse/pull/64084) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add metrics, logs, and thread names around parts filtering with indices. [#64130](https://github.com/ClickHouse/ClickHouse/pull/64130) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Ignore `allow_suspicious_primary_key` on `ATTACH` and verify on `ALTER`. [#64202](https://github.com/ClickHouse/ClickHouse/pull/64202) ([Azat Khuzhin](https://github.com/azat)).
+
+#### Build/Testing/Packaging Improvement
+* ClickHouse is built with clang-18. A lot of new checks from clang-tidy-18 have been enabled. [#60469](https://github.com/ClickHouse/ClickHouse/pull/60469) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Experimentally support loongarch64 as a new platform for ClickHouse. [#63733](https://github.com/ClickHouse/ClickHouse/pull/63733) ([qiangxuhui](https://github.com/qiangxuhui)).
+* The Dockerfile is reviewed by the docker official library in https://github.com/docker-library/official-images/pull/15846. [#63400](https://github.com/ClickHouse/ClickHouse/pull/63400) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Information about every symbol in every translation unit will be collected in the CI database for every build in the CI.

 ### <a id="244"></a> ClickHouse release 24.4, 2024-04-30
 
 #### Upgrade Notes
@@ -506,7 +663,7 @@
 * Improve the operation of `sumMapFiltered` with NaN values. NaN values are now placed at the end (instead of randomly) and considered different from any values. `-0` is now also treated as equal to `0`; since 0 values are discarded, `-0` values are discarded too. [#58959](https://github.com/ClickHouse/ClickHouse/pull/58959) ([Raúl Marín](https://github.com/Algunenano)).
 * The function `visibleWidth` will behave according to the docs. In previous versions, it simply counted code points after string serialization, like the `lengthUTF8` function, but didn't consider zero-width and combining characters, full-width characters, tabs, and deletes. Now the behavior is changed accordingly. If you want to keep the old behavior, set `function_visible_width_behavior` to `0`, or set `compatibility` to `23.12` or lower. [#59022](https://github.com/ClickHouse/ClickHouse/pull/59022) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
 * `Kusto` dialect is disabled until these two bugs will be fixed: [#59037](https://github.com/ClickHouse/ClickHouse/issues/59037) and [#59036](https://github.com/ClickHouse/ClickHouse/issues/59036). [#59305](https://github.com/ClickHouse/ClickHouse/pull/59305) ([Alexey Milovidov](https://github.com/alexey-milovidov)). Any attempt to use `Kusto` will result in exception.
-* More efficient implementation of the `FINAL` modifier no longer guarantees preserving the order even if `max_threads = 1`. If you counted on the previous behavior, set `enable_vertical_final` to 0 or `compatibility` to `23.12`. 
+* More efficient implementation of the `FINAL` modifier no longer guarantees preserving the order even if `max_threads = 1`. If you counted on the previous behavior, set `enable_vertical_final` to 0 or `compatibility` to `23.12`.
 
 #### New Feature
 * Implement Variant data type that represents a union of other data types. Type `Variant(T1, T2, ..., TN)` means that each row of this type has a value of either type `T1` or `T2` or ... or `TN` or none of them (`NULL` value). Variant type is available under a setting `allow_experimental_variant_type`. Reference: [#54864](https://github.com/ClickHouse/ClickHouse/issues/54864). [#58047](https://github.com/ClickHouse/ClickHouse/pull/58047) ([Kruglov Pavel](https://github.com/Avogar)).

 * Support negative positional arguments. Closes [#57736](https://github.com/ClickHouse/ClickHouse/issues/57736). [#58292](https://github.com/ClickHouse/ClickHouse/pull/58292) ([flynn](https://github.com/ucasfl)).
 * Implement auto-adjustment for asynchronous insert timeouts. The following settings are introduced: async_insert_poll_timeout_ms, async_insert_use_adaptive_busy_timeout, async_insert_busy_timeout_min_ms, async_insert_busy_timeout_max_ms, async_insert_busy_timeout_increase_rate, async_insert_busy_timeout_decrease_rate. [#58486](https://github.com/ClickHouse/ClickHouse/pull/58486) ([Julia Kartseva](https://github.com/jkartseva)).
 * Allow to define `volume_priority` in `storage_configuration`. [#58533](https://github.com/ClickHouse/ClickHouse/pull/58533) ([Andrey Zvonov](https://github.com/zvonand)).
-* Add support for Date32 type in T64 codec. [#58738](https://github.com/ClickHouse/ClickHouse/pull/58738) ([Hongbin Ma](https://github.com/binmahone)).
+* Add support for Date32 type in T64 codec. [#58738](https://github.com/ClickHouse/ClickHouse/pull/58738) ([Hongbin Ma (Mahone)](https://github.com/binmahone)).
 * Support `LEFT JOIN`, `ALL INNER JOIN`, and simple subqueries for parallel replicas (only with analyzer). New setting `parallel_replicas_prefer_local_join` chooses local `JOIN` execution (by default) vs `GLOBAL JOIN`. All tables should exist on every replica from `cluster_for_parallel_replicas`. New settings `min_external_table_block_size_rows` and `min_external_table_block_size_bytes` are used to squash small blocks that are sent for temporary tables (only with analyzer). [#58916](https://github.com/ClickHouse/ClickHouse/pull/58916) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
 * Allow trailing commas in types with several items. [#59119](https://github.com/ClickHouse/ClickHouse/pull/59119) ([Aleksandr Musorin](https://github.com/AVMusorin)).
 * Allow parallel and distributed processing for `S3Queue` table engine. For distributed processing use setting `s3queue_total_shards_num` (by default `1`). Setting `s3queue_processing_threads_num` previously was not allowed for Ordered processing mode, now it is allowed. Warning: settings `s3queue_processing_threads_num`(processing threads per each shard) and `s3queue_total_shards_num` for ordered mode change how metadata is stored (make the number of `max_processed_file` nodes equal to `s3queue_processing_threads_num * s3queue_total_shards_num`), so they must be the same for all shards and cannot be changed once at least one shard is created.

 #### Bug Fix (user-visible misbehavior in an official stable release)
 
-* Non ready set in TTL WHERE. [#57430](https://github.com/ClickHouse/ClickHouse/pull/57430) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Support `IN (subquery)` in table TTL expression. Initially, it was allowed to create such a TTL expression, but any TTL merge would fail with `Not-ready Set` error in the background. Now, TTL is correctly applied. Subquery is executed for every TTL merge, and its result is not cached or reused by other merges. Use such configuration with special care, because subqueries in TTL may lead to high memory consumption and, possibly, a non-deterministic result of TTL merge on different replicas (which is correctly handled by replication, however). [#57430](https://github.com/ClickHouse/ClickHouse/pull/57430) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

-1. Each third-party library must reside in a dedicated directory under the `contrib/` directory of the ClickHouse repository. Avoid dumps/copies of external code, instead use Git submodule feature to pull third-party code from an external upstream repository.
+Each third-party library must reside in a dedicated directory under the `contrib/` directory of the ClickHouse repository.
-2. Submodules are listed in `.gitmodule`. If the external library can be used as-is, you may reference the upstream repository directly. Otherwise, i.e. the external library requires patching/customization, create a fork of the official repository in the [ClickHouse organization in GitHub](https://github.com/ClickHouse).
+Avoid dumping copies of external code into the library directory.
-3. In the latter case, create a branch with `clickhouse/` prefix from the branch you want to integrate, e.g. `clickhouse/master` (for `master`) or `clickhouse/release/vX.Y.Z` (for a `release/vX.Y.Z` tag). The purpose of this branch is to isolate customization of the library from upstream work. For example, pulls from the upstream repository into the fork will leave all `clickhouse/` branches unaffected. Submodules in `contrib/` must only track `clickhouse/` branches of forked third-party repositories.
+Instead create a Git submodule to pull third-party code from an external upstream repository.
-4. To patch a fork of a third-party library, create a dedicated branch with `clickhouse/` prefix in the fork, e.g. `clickhouse/fix-some-desaster`. Finally, merge the patch branch into the custom tracking branch (e.g. `clickhouse/master` or `clickhouse/release/vX.Y.Z`) using a PR.
+
-5. Always create patches of third-party libraries with the official repository in mind. Once a PR of a patch branch to the `clickhouse/` branch in the fork repository is done and the submodule version in ClickHouse official repository is bumped, consider opening another PR from the patch branch to the upstream library repository. This ensures, that 1) the contribution has more than a single use case and importance, 2) others will also benefit from it, 3) the change will not remain a maintenance burden solely on ClickHouse developers.
+All submodules used by ClickHouse are listed in the `.gitmodule` file.
-9. To update a submodule with changes in the upstream repository, first merge upstream `master` (or a new `versionX.Y.Z` tag) into the `clickhouse`-tracking branch in the fork repository. Conflicts with patches/customization will need to be resolved in this merge (see Step 4.). Once the merge is done, bump the submodule in ClickHouse to point to the new hash in the fork.
+If the library can be used as-is (the default case), you can reference the upstream repository directly.
+If the library needs patching, create a fork of the upstream repository in the [ClickHouse organization on GitHub](https://github.com/ClickHouse).
+
+In the latter case, we aim to isolate custom patches as much as possible from upstream commits.
+To that end, create a branch with prefix `clickhouse/` from the branch or tag you want to integrate, e.g. `clickhouse/master` (for branch `master`) or `clickhouse/release/vX.Y.Z` (for tag `release/vX.Y.Z`).
+This ensures that pulls from the upstream repository into the fork will leave custom `clickhouse/` branches unaffected.
+Submodules in `contrib/` must only track `clickhouse/` branches of forked third-party repositories.
+
+Patches are only applied against `clickhouse/` branches of external libraries.
+For that, push the patch as a branch with `clickhouse/`, e.g. `clickhouse/fix-some-desaster`.
+Then create a PR from the new branch against the custom tracking branch with `clickhouse/` prefix, (e.g. `clickhouse/master` or `clickhouse/release/vX.Y.Z`) and merge the patch.
+
+Create patches of third-party libraries with the official repository in mind and consider contributing the patch back to the upstream repository.
+This makes sure that others will also benefit from the patch and it will not be a maintenance burden for the ClickHouse team.
+
+To pull upstream changes into the submodule, you can use two methods:
+- (less work but less clean): merge upstream `master` into the corresponding `clickhouse/` tracking branch in the forked repository. You will need to resolve merge conflicts with previous custom patches. This method can be used when the `clickhouse/` branch tracks an upstream development branch like `master`, `main`, `dev`, etc.
+- (more work but cleaner): create a new branch with `clickhouse/` prefix from the upstream commit or tag you like to integrate. Then re-apply all existing patches using new PRs (or squash them into a single PR). This method can be used when the `clickhouse/` branch tracks a specific upstream version branch or tag. It is cleaner in the sense that custom patches and upstream changes are better isolated from each other.
+
+Once the submodule has been updated, bump the submodule in ClickHouse to point to the new hash in the fork.

-
-Generates a [UUID](../data-types/uuid.md) of [version 7](https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format-04).
-
-The generated UUID contains the current Unix timestamp in milliseconds (48 bits), followed by version "7" (4 bits), a counter (42 bit) to distinguish UUIDs within a millisecond (including a variant field "2", 2 bit), and a random field (32 bits).
-For any given timestamp (unix_ts_ms), the counter starts at a random value and is incremented by 1 for each new UUID until the timestamp changes.
-In case the counter overflows, the timestamp field is incremented by 1 and the counter is reset to a random new start value.
-
-This function behaves like [generateUUIDv7](#generateUUIDv7) but gives no guarantee on counter monotony across different simultaneous requests.
-Monotonicity within one timestamp is guaranteed only within the same thread calling this function to generate UUIDs.

 If you specify `POPULATE`, the existing table data is inserted into the view when creating it, as if making a `CREATE TABLE ... AS SELECT ...` . Otherwise, the query contains only the data inserted in the table after creating the view. We **do not recommend** using `POPULATE`, since data inserted in the table during the view creation will not be inserted in it.
 
+:::note
+Given that `POPULATE` works like `CREATE TABLE ... AS SELECT ...` it has limitations:
+- It is not supported with Replicated database
+- It is not supported in ClickHouse cloud
+
+Instead a separate `INSERT ... SELECT` can be used.  
+:::
+
 A `SELECT` query can contain `DISTINCT`, `GROUP BY`, `ORDER BY`, `LIMIT`. Note that the corresponding conversions are performed independently on each block of inserted data. For example, if `GROUP BY` is set, data is aggregated during insertion, but only within a single packet of inserted data. The data won’t be further aggregated. The exception is when using an `ENGINE` that independently performs data aggregation, such as `SummingMergeTree`.
 
 The execution of [ALTER](/docs/en/sql-reference/statements/alter/view.md) queries on materialized views has limitations, for example, you can not update the `SELECT` query, so this might be inconvenient. If the materialized view uses the construction `TO [db.]name`, you can `DETACH` the view, run `ALTER` for the target table, and then `ATTACH` the previously detached (`DETACH`) view.

 Чтобы использовать различные [версии ClickHouse](../faq/operations/production.md) в зависимости от ваших потребностей, вы можете заменить `stable` на `lts` или `testing`.
 
 Также вы можете вручную скачать и установить пакеты из [репозитория](https://packages.clickhouse.com/deb/pool/stable).

-Генерирует идентификатор [UUID версии 7](https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format-04). Генерируемый UUID состоит из 48-битной временной метки (Unix time в миллисекундах), маркеров версии 7 и варианта 2, монотонно возрастающего счётчика для данной временной метки и случайных данных в указанной ниже последовательности. Для каждой новой временной метки счётчик стартует с нового случайного значения, а для следующих UUIDv7 он увеличивается на единицу. В случае переполнения счётчика временная метка принудительно увеличивается на 1, и счётчик снова стартует со случайного значения. Данная функция является ускоренным аналогом функции `generateUUIDv7` за счёт потери гарантии монотонности счётчика при одной и той же метке времени между одновременно исполняемыми разными запросами. Монотонность счётчика гарантируется только в пределах одного треда, исполняющего данную функцию для генерации нескольких UUID.

In case the counter overflows, the timestamp field is incremented by 1 and the counter is reset to a random new start value. This function behaves like generateUUIDv7 but gives no guarantee on counter monotony across different simultaneous requests. Monotonicity within one timestamp is guaranteed only within the same thread calling this function to generate UUIDs.)";
