+
+#### Backward Incompatible Change
+* Remove support for octal number literals in SQL. In previous versions they were parsed as Float64. [#37765](https://github.com/ClickHouse/ClickHouse/pull/37765) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Changes how settings using `seconds` as type are parsed to support floating point values (for example: `max_execution_time=0.5`). Infinity or NaN values will throw an exception. [#37187](https://github.com/ClickHouse/ClickHouse/pull/37187) ([Raúl Marín](https://github.com/Algunenano)).
+* Changed format of binary serialization of columns of experimental type `Object`. New format is more convenient to implement by third-party clients. [#37482](https://github.com/ClickHouse/ClickHouse/pull/37482) ([Anton Popov](https://github.com/CurtizJ)).
+* Turn on setting `output_format_json_named_tuples_as_objects` by default. It allows to serialize named tuples as JSON objects in JSON formats. [#37756](https://github.com/ClickHouse/ClickHouse/pull/37756) ([Anton Popov](https://github.com/CurtizJ)).
+* LIKE patterns with trailing escape symbol ('\\') are now disallowed (as mandated by the SQL standard). [#37764](https://github.com/ClickHouse/ClickHouse/pull/37764) ([Robert Schulze](https://github.com/rschu1ze)).
+* If you run different ClickHouse versions on a cluster with AArch64 CPU or mix AArch64 and amd64 on a cluster, and use distributed queries with GROUP BY multiple keys of fixed-size type that fit in 256 bits but don't fit in 64 bits, and the size of the result is huge, the data will not be fully aggregated in the result of these queries during upgrade. Workaround: upgrade with downtime instead of a rolling upgrade.
+
+#### New Feature
+* Add `GROUPING` function. It allows to disambiguate the records in the queries with `ROLLUP`, `CUBE` or `GROUPING SETS`. Closes [#19426](https://github.com/ClickHouse/ClickHouse/issues/19426). [#37163](https://github.com/ClickHouse/ClickHouse/pull/37163) ([Dmitry Novik](https://github.com/novikd)).
+* A new codec [FPC](https://userweb.cs.txstate.edu/~burtscher/papers/dcc07a.pdf) algorithm for floating point data compression. [#37553](https://github.com/ClickHouse/ClickHouse/pull/37553) ([Mikhail Guzov](https://github.com/koloshmet)).
+* Add new columnar JSON formats: `JSONColumns`, `JSONCompactColumns`, `JSONColumnsWithMetadata`. Closes [#36338](https://github.com/ClickHouse/ClickHouse/issues/36338) Closes [#34509](https://github.com/ClickHouse/ClickHouse/issues/34509). [#36975](https://github.com/ClickHouse/ClickHouse/pull/36975) ([Kruglov Pavel](https://github.com/Avogar)).
+* Added open telemetry traces visualizing tool based on d3js. [#37810](https://github.com/ClickHouse/ClickHouse/pull/37810) ([Sergei Trifonov](https://github.com/serxa)).
+* Support INSERTs into `system.zookeeper` table. Closes [#22130](https://github.com/ClickHouse/ClickHouse/issues/22130). [#37596](https://github.com/ClickHouse/ClickHouse/pull/37596) ([Han Fei](https://github.com/hanfei1991)).
+* Support non-constant pattern argument for `LIKE`, `ILIKE` and `match` functions. [#37251](https://github.com/ClickHouse/ClickHouse/pull/37251) ([Robert Schulze](https://github.com/rschu1ze)).
+* Executable user defined functions now support parameters. Example: `SELECT test_function(parameters)(arguments)`. Closes [#37578](https://github.com/ClickHouse/ClickHouse/issues/37578). [#37720](https://github.com/ClickHouse/ClickHouse/pull/37720) ([Maksim Kita](https://github.com/kitaisreal)).
+* Add `merge_reason` column to system.part_log table. [#36912](https://github.com/ClickHouse/ClickHouse/pull/36912) ([Sema Checherinda](https://github.com/CheSema)).
+* Add support for Maps and Records in Avro format. Add new setting `input_format_avro_null_as_default ` that allow to insert null as default in Avro format. Closes [#18925](https://github.com/ClickHouse/ClickHouse/issues/18925) Closes [#37378](https://github.com/ClickHouse/ClickHouse/issues/37378) Closes [#32899](https://github.com/ClickHouse/ClickHouse/issues/32899). [#37525](https://github.com/ClickHouse/ClickHouse/pull/37525) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add `clickhouse-disks` tool to introspect and operate on virtual filesystems configured for ClickHouse. [#36060](https://github.com/ClickHouse/ClickHouse/pull/36060) ([Artyom Yurkov](https://github.com/Varinara)).
+* Adds H3 unidirectional edge functions. [#36843](https://github.com/ClickHouse/ClickHouse/pull/36843) ([Bharat Nallan](https://github.com/bharatnc)).
+* Add support for calculating [hashids](https://hashids.org/) from unsigned integers. [#37013](https://github.com/ClickHouse/ClickHouse/pull/37013) ([Michael Nutt](https://github.com/mnutt)).
+* Explicit `SALT` specification is allowed for `CREATE USER <user> IDENTIFIED WITH sha256_hash`. [#37377](https://github.com/ClickHouse/ClickHouse/pull/37377) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Add two new settings `input_format_csv_skip_first_lines/input_format_tsv_skip_first_lines` to allow skipping specified number of lines in the beginning of the file in CSV/TSV formats. [#37537](https://github.com/ClickHouse/ClickHouse/pull/37537) ([Kruglov Pavel](https://github.com/Avogar)).
+* `showCertificate` function shows current server's SSL certificate. [#37540](https://github.com/ClickHouse/ClickHouse/pull/37540) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* HTTP source for Data Dictionaries in Named Collections is supported. [#37581](https://github.com/ClickHouse/ClickHouse/pull/37581) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Added a new window function `nonNegativeDerivative(metric_column, timestamp_column[, INTERVAL x SECOND])`. [#37628](https://github.com/ClickHouse/ClickHouse/pull/37628) ([Andrey Zvonov](https://github.com/zvonand)).
+* Implemented changing the comment for `ReplicatedMergeTree` tables. [#37416](https://github.com/ClickHouse/ClickHouse/pull/37416) ([Vasily Nemkov](https://github.com/Enmk)).
+* Added `SYSTEM UNFREEZE` query that deletes the whole backup regardless if the corresponding table is deleted or not. [#36424](https://github.com/ClickHouse/ClickHouse/pull/36424) ([Vadim Volodin](https://github.com/PolyProgrammist)).
+
+#### Experimental Feature
+* Enables `POPULATE` for `WINDOW VIEW`. [#36945](https://github.com/ClickHouse/ClickHouse/pull/36945) ([vxider](https://github.com/Vxider)).
+* `ALTER TABLE ... MODIFY QUERY` support for `WINDOW VIEW`. [#37188](https://github.com/ClickHouse/ClickHouse/pull/37188) ([vxider](https://github.com/Vxider)).
+* This PR changes the behavior of the `ENGINE` syntax in `WINDOW VIEW`, to make it like in `MATERIALIZED VIEW`. [#37214](https://github.com/ClickHouse/ClickHouse/pull/37214) ([vxider](https://github.com/Vxider)).
+
+#### Performance Improvement
+* Added numerous optimizations for ARM NEON [#38093](https://github.com/ClickHouse/ClickHouse/pull/38093)([Daniel Kutenin](https://github.com/danlark1)), ([Alexandra Pilipyuk](https://github.com/chalice19)) Note: if you run different ClickHouse versions on a cluster with ARM CPU and use distributed queries with GROUP BY multiple keys of fixed-size type that fit in 256 bits but don't fit in 64 bits, the result of the aggregation query will be wrong during upgrade. Workaround: upgrade with downtime instead of a rolling upgrade.
+* Improve performance and memory usage for select of subset of columns for formats Native, Protobuf, CapnProto, JSONEachRow, TSKV, all formats with suffixes WithNames/WithNamesAndTypes. Previously while selecting only subset of columns from files in these formats all columns were read and stored in memory. Now only required columns are read. This PR enables setting `input_format_skip_unknown_fields` by default, because otherwise in case of select of subset of columns exception will be thrown. [#37192](https://github.com/ClickHouse/ClickHouse/pull/37192) ([Kruglov Pavel](https://github.com/Avogar)).
+* Now more filters can be pushed down for join. [#37472](https://github.com/ClickHouse/ClickHouse/pull/37472) ([Amos Bird](https://github.com/amosbird)).
+* Load marks for only necessary columns when reading wide parts. [#36879](https://github.com/ClickHouse/ClickHouse/pull/36879) ([Anton Kozlov](https://github.com/tonickkozlov)).
+* Improved performance of aggregation in case, when sparse columns (can be enabled by experimental setting `ratio_of_defaults_for_sparse_serialization` in `MergeTree` tables) are used as arguments in aggregate functions. [#37617](https://github.com/ClickHouse/ClickHouse/pull/37617) ([Anton Popov](https://github.com/CurtizJ)).
+* Optimize function `COALESCE` with two arguments. [#37666](https://github.com/ClickHouse/ClickHouse/pull/37666) ([Anton Popov](https://github.com/CurtizJ)).
+* Replace `multiIf` to `if` in case when `multiIf` has only one condition, because function `if` is more performant. [#37695](https://github.com/ClickHouse/ClickHouse/pull/37695) ([Anton Popov](https://github.com/CurtizJ)).
+* Improve performance of `dictGetDescendants`, `dictGetChildren` functions, create temporary parent to children hierarchical index per query, not per function call during query. Allow to specify `BIDIRECTIONAL` for `HIERARHICAL` attributes, dictionary will maintain parent to children index in memory, that way functions `dictGetDescendants`, `dictGetChildren` will not create temporary index per query. Closes [#32481](https://github.com/ClickHouse/ClickHouse/issues/32481). [#37148](https://github.com/ClickHouse/ClickHouse/pull/37148) ([Maksim Kita](https://github.com/kitaisreal)).
+* Aggregates state destruction now may be posted on a thread pool. For queries with LIMIT and big state it provides significant speedup, e.g. `select uniq(number) from numbers_mt(1e7) group by number limit 100` became around 2.5x faster. [#37855](https://github.com/ClickHouse/ClickHouse/pull/37855) ([Nikita Taranov](https://github.com/nickitat)).
+* Improve sort performance by single column. [#37195](https://github.com/ClickHouse/ClickHouse/pull/37195) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of single column sorting using sorting queue specializations. [#37990](https://github.com/ClickHouse/ClickHouse/pull/37990) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improved performance on array norm and distance functions 2x-4x times. [#37394](https://github.com/ClickHouse/ClickHouse/pull/37394) ([Alexander Gololobov](https://github.com/davenger)).
+* Improve performance of number comparison functions using dynamic dispatch. [#37399](https://github.com/ClickHouse/ClickHouse/pull/37399) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of ORDER BY with LIMIT. [#37481](https://github.com/ClickHouse/ClickHouse/pull/37481) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of `hasAll` function using dynamic dispatch infrastructure. [#37484](https://github.com/ClickHouse/ClickHouse/pull/37484) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of `greatCircleAngle`, `greatCircleDistance`, `geoDistance` functions. [#37524](https://github.com/ClickHouse/ClickHouse/pull/37524) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of insert into MergeTree if there are multiple columns in ORDER BY. [#35762](https://github.com/ClickHouse/ClickHouse/pull/35762) ([Maksim Kita](https://github.com/kitaisreal)).
+* Fix excessive CPU usage in background when there are a lot of tables. [#38028](https://github.com/ClickHouse/ClickHouse/pull/38028) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of `not` function using dynamic dispatch. [#38058](https://github.com/ClickHouse/ClickHouse/pull/38058) ([Maksim Kita](https://github.com/kitaisreal)).
+* Optimized the internal caching of re2 patterns which occur e.g. in LIKE and MATCH functions. [#37544](https://github.com/ClickHouse/ClickHouse/pull/37544) ([Robert Schulze](https://github.com/rschu1ze)).
+* Improve filter bitmask generator function all in one with AVX-512 instructions. [#37588](https://github.com/ClickHouse/ClickHouse/pull/37588) ([yaqi-zhao](https://github.com/yaqi-zhao)).
+* Apply read method `threadpool` for Hive integration engine. This will significantly speed up reading. [#36328](https://github.com/ClickHouse/ClickHouse/pull/36328) ([李扬](https://github.com/taiyang-li)).
+* When all the columns to read are partition keys, construct columns by the file's row number without real reading the Hive file. [#37103](https://github.com/ClickHouse/ClickHouse/pull/37103) ([lgbo](https://github.com/lgbo-ustc)).
+* Support multi disks for caching hive files. [#37279](https://github.com/ClickHouse/ClickHouse/pull/37279) ([lgbo](https://github.com/lgbo-ustc)).
+* Limiting the maximum cache usage per query can effectively prevent cache pool contamination. [Related Issues](https://github.com/ClickHouse/ClickHouse/issues/28961). [#37859](https://github.com/ClickHouse/ClickHouse/pull/37859) ([Han Shukai](https://github.com/KinderRiven)).
+* Currently clickhouse directly downloads all remote files to the local cache (even if they are only read once), which will frequently cause IO of the local hard disk. In some scenarios, these IOs may not be necessary and may easily cause negative optimization. As shown in the figure below, when we run SSB Q1-Q4, the performance of the cache has caused negative optimization. [#37516](https://github.com/ClickHouse/ClickHouse/pull/37516) ([Han Shukai](https://github.com/KinderRiven)).
+* Allow to prune the list of files via virtual columns such as `_file` and `_path` when reading from S3. This is for [#37174](https://github.com/ClickHouse/ClickHouse/issues/37174) , [#23494](https://github.com/ClickHouse/ClickHouse/issues/23494). [#37356](https://github.com/ClickHouse/ClickHouse/pull/37356) ([Amos Bird](https://github.com/amosbird)).
+* In function: CompressedWriteBuffer::nextImpl(), there is an unnecessary write-copy step that would happen frequently during inserting data. Below shows the differentiation with this patch: - Before: 1. Compress "working_buffer" into "compressed_buffer" 2. write-copy into "out" - After: Directly Compress "working_buffer" into "out". [#37242](https://github.com/ClickHouse/ClickHouse/pull/37242) ([jasperzhu](https://github.com/jinjunzh)).
+
+#### Improvement
+* Support types with non-standard defaults in ROLLUP, CUBE, GROUPING SETS. Closes [#37360](https://github.com/ClickHouse/ClickHouse/issues/37360). [#37667](https://github.com/ClickHouse/ClickHouse/pull/37667) ([Dmitry Novik](https://github.com/novikd)).
+* Fix stack traces collection on ARM. Closes [#37044](https://github.com/ClickHouse/ClickHouse/issues/37044). Closes [#15638](https://github.com/ClickHouse/ClickHouse/issues/15638). [#37797](https://github.com/ClickHouse/ClickHouse/pull/37797) ([Maksim Kita](https://github.com/kitaisreal)).
+* Client will try every IP address returned by DNS resolution until successful connection. [#37273](https://github.com/ClickHouse/ClickHouse/pull/37273) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Allow to use String type instead of Binary in Arrow/Parquet/ORC formats. This PR introduces 3 new settings for it: `output_format_arrow_string_as_string`, `output_format_parquet_string_as_string`, `output_format_orc_string_as_string`. Default value for all settings is `false`. [#37327](https://github.com/ClickHouse/ClickHouse/pull/37327) ([Kruglov Pavel](https://github.com/Avogar)).
+* Apply setting `input_format_max_rows_to_read_for_schema_inference` for all read rows in total from all files in globs. Previously setting `input_format_max_rows_to_read_for_schema_inference` was applied for each file in glob separately and in case of huge number of nulls we could read first `input_format_max_rows_to_read_for_schema_inference` rows from each file and get nothing. Also increase default value for this setting to 25000. [#37332](https://github.com/ClickHouse/ClickHouse/pull/37332) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add separate `CLUSTER` grant (and `access_control_improvements.on_cluster_queries_require_cluster_grant` configuration directive, for backward compatibility, default to `false`). [#35767](https://github.com/ClickHouse/ClickHouse/pull/35767) ([Azat Khuzhin](https://github.com/azat)).
+* Added support for schema inference for `hdfsCluster`. [#35812](https://github.com/ClickHouse/ClickHouse/pull/35812) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Implement `least_used` load balancing algorithm for disks inside volume (multi disk configuration). [#36686](https://github.com/ClickHouse/ClickHouse/pull/36686) ([Azat Khuzhin](https://github.com/azat)).
+* Modify the HTTP Endpoint to return the full stats under the `X-ClickHouse-Summary` header when `send_progress_in_http_headers=0` (before it would return all zeros). - Modify the HTTP Endpoint to return `X-ClickHouse-Exception-Code` header when progress has been sent before (`send_progress_in_http_headers=1`) - Modify the HTTP Endpoint to return `HTTP_REQUEST_TIMEOUT` (408) instead of `HTTP_INTERNAL_SERVER_ERROR` (500) on `TIMEOUT_EXCEEDED` errors. [#36884](https://github.com/ClickHouse/ClickHouse/pull/36884) ([Raúl Marín](https://github.com/Algunenano)).
+* Allow a user to inspect grants from granted roles. [#36941](https://github.com/ClickHouse/ClickHouse/pull/36941) ([nvartolomei](https://github.com/nvartolomei)).
+* Do not calculate an integral numerically but use CDF functions instead. This will speed up execution and will increase the precision. This fixes [#36714](https://github.com/ClickHouse/ClickHouse/issues/36714). [#36953](https://github.com/ClickHouse/ClickHouse/pull/36953) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add default implementation for Nothing in functions. Now most of the functions will return column with type Nothing in case one of it's arguments is Nothing. It also solves problem with functions like arrayMap/arrayFilter and similar when they have empty array as an argument. Previously queries like `select arrayMap(x -> 2 * x, []);` failed because function inside lambda cannot work with type `Nothing`, now such queries return empty array with type `Array(Nothing)`. Also add support for arrays of nullable types in functions like arrayFilter/arrayFill. Previously, queries like `select arrayFilter(x -> x % 2, [1, NULL])` failed, now they work (if the result of lambda is NULL, then this value won't be included in the result). Closes [#37000](https://github.com/ClickHouse/ClickHouse/issues/37000). [#37048](https://github.com/ClickHouse/ClickHouse/pull/37048) ([Kruglov Pavel](https://github.com/Avogar)).
+* Now if a shard has local replica we create a local plan and a plan to read from all remote replicas. They have shared initiator which coordinates reading. [#37204](https://github.com/ClickHouse/ClickHouse/pull/37204) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Do no longer abort server startup if configuration option "mark_cache_size" is not explicitly set. [#37326](https://github.com/ClickHouse/ClickHouse/pull/37326) ([Robert Schulze](https://github.com/rschu1ze)).
+* Allows providing `NULL`/`NOT NULL` right after type in column declaration. [#37337](https://github.com/ClickHouse/ClickHouse/pull/37337) ([Igor Nikonov](https://github.com/devcrafter)).
+* optimize file segment PARTIALLY_DOWNLOADED get read buffer. [#37338](https://github.com/ClickHouse/ClickHouse/pull/37338) ([xiedeyantu](https://github.com/xiedeyantu)).
+* Try to improve short circuit functions processing to fix problems with stress tests. [#37384](https://github.com/ClickHouse/ClickHouse/pull/37384) ([Kruglov Pavel](https://github.com/Avogar)).
+* Closes [#37395](https://github.com/ClickHouse/ClickHouse/issues/37395). [#37415](https://github.com/ClickHouse/ClickHouse/pull/37415) ([Memo](https://github.com/Joeywzr)).
+* Fix extremely rare deadlock during part fetch in zero-copy replication. Fixes [#37423](https://github.com/ClickHouse/ClickHouse/issues/37423). [#37424](https://github.com/ClickHouse/ClickHouse/pull/37424) ([metahys](https://github.com/metahys)).
+* Don't allow to create storage with unknown data format. [#37450](https://github.com/ClickHouse/ClickHouse/pull/37450) ([Kruglov Pavel](https://github.com/Avogar)).
+* Set `global_memory_usage_overcommit_max_wait_microseconds` default value to 5 seconds. Add info about `OvercommitTracker` to OOM exception message. Add `MemoryOvercommitWaitTimeMicroseconds` profile event. [#37460](https://github.com/ClickHouse/ClickHouse/pull/37460) ([Dmitry Novik](https://github.com/novikd)).
+* Do not display `-0.0` CPU time in clickhouse-client. It can appear due to rounding errors. This closes [#38003](https://github.com/ClickHouse/ClickHouse/issues/38003). This closes [#38038](https://github.com/ClickHouse/ClickHouse/issues/38038). [#38064](https://github.com/ClickHouse/ClickHouse/pull/38064) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Play UI: Keep controls in place when the page is scrolled horizontally. This makes edits comfortable even if the table is wide and it was scrolled far to the right. The feature proposed by Maksym Tereshchenko from CaspianDB. [#37470](https://github.com/ClickHouse/ClickHouse/pull/37470) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Modify query div in play.html to be extendable beyond 20% height. In case of very long queries it is helpful to extend the textarea element, only today, since the div is fixed height, the extended textarea hides the data div underneath. With this fix, extending the textarea element will push the data div down/up such the extended textarea won't hide it. Also, keeps query box width 100% even when the user adjusting the size of the query textarea. [#37488](https://github.com/ClickHouse/ClickHouse/pull/37488) ([guyco87](https://github.com/guyco87)).
+* Added `ProfileEvents` for introspection of type of written (inserted or merged) parts (`Inserted{Wide/Compact/InMemory}Parts`, `MergedInto{Wide/Compact/InMemory}Parts`. Added column `part_type` to `system.part_log`. Resolves [#37495](https://github.com/ClickHouse/ClickHouse/issues/37495). [#37536](https://github.com/ClickHouse/ClickHouse/pull/37536) ([Anton Popov](https://github.com/CurtizJ)).
+* clickhouse-keeper improvement: move broken logs to a timestamped folder. [#37565](https://github.com/ClickHouse/ClickHouse/pull/37565) ([Antonio Andelic](https://github.com/antonio2368)).
+* Do not write expired columns by TTL after subsequent merges (before only first merge/optimize of the part will not write expired by TTL columns, all other will do). [#37570](https://github.com/ClickHouse/ClickHouse/pull/37570) ([Azat Khuzhin](https://github.com/azat)).
+* More precise result of the `dumpColumnStructure` miscellaneous function in presence of LowCardinality or Sparse columns. In previous versions, these functions were converting the argument to a full column before returning the result. This is needed to provide an answer in [#6935](https://github.com/ClickHouse/ClickHouse/issues/6935). [#37633](https://github.com/ClickHouse/ClickHouse/pull/37633) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* clickhouse-keeper: store only unique session IDs for watches. [#37641](https://github.com/ClickHouse/ClickHouse/pull/37641) ([Azat Khuzhin](https://github.com/azat)).
+* Fix possible "Cannot write to finalized buffer". [#37645](https://github.com/ClickHouse/ClickHouse/pull/37645) ([Azat Khuzhin](https://github.com/azat)).
+* Add setting `support_batch_delete` for `DiskS3` to disable multiobject delete calls, which Google Cloud Storage doesn't support. [#37659](https://github.com/ClickHouse/ClickHouse/pull/37659) ([Fred Wulff](https://github.com/frew)).
+* Add an option to disable connection pooling in ODBC bridge. [#37705](https://github.com/ClickHouse/ClickHouse/pull/37705) ([Anton Kozlov](https://github.com/tonickkozlov)).
+* Functions `dictGetHierarchy`, `dictIsIn`, `dictGetChildren`, `dictGetDescendants` added support nullable `HIERARCHICAL` attribute in dictionaries. Closes [#35521](https://github.com/ClickHouse/ClickHouse/issues/35521). [#37805](https://github.com/ClickHouse/ClickHouse/pull/37805) ([Maksim Kita](https://github.com/kitaisreal)).
+* Expose BoringSSL version related info in the `system.build_options` table. [#37850](https://github.com/ClickHouse/ClickHouse/pull/37850) ([Bharat Nallan](https://github.com/bharatnc)).

+
+#### Build/Testing/Packaging Improvement
+* Use `clang-14` and LLVM infrastructure version 14 for builds. This closes [#34681](https://github.com/ClickHouse/ClickHouse/issues/34681). [#34754](https://github.com/ClickHouse/ClickHouse/pull/34754) ([Alexey Milovidov](https://github.com/alexey-milovidov)). Note: `clang-14` has [a bug](https://github.com/google/sanitizers/issues/1540) in ThreadSanitizer that makes our CI work worse.
+* Allow to drop privileges at startup. This simplifies Docker images. Closes [#36293](https://github.com/ClickHouse/ClickHouse/issues/36293). [#36341](https://github.com/ClickHouse/ClickHouse/pull/36341) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

 ## Reporting a Vulnerability
 
@@ -57,4 +59,3 @@ As the security issue moves from triage, to identified fix, to release planning
 
 A public disclosure date is negotiated by the ClickHouse maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to 90 days. For a vulnerability with a straightforward mitigation, we expect report date to disclosure date to be on the order of 7 days.

+* Load marks for only necessary columns when reading wide parts. [#36879](https://github.com/ClickHouse/ClickHouse/pull/36879) ([Anton Kozlov](https://github.com/tonickkozlov)).
+* When all the columns to read are partition keys, construct columns by the file's row number without real reading the hive file. [#37103](https://github.com/ClickHouse/ClickHouse/pull/37103) ([lgbo](https://github.com/lgbo-ustc)).
+* Fix performance of `dictGetDescendants`, `dictGetChildren` functions, create temporary parent to children hierarchical index per query, not per function call during query. Allow to specify `BIDIRECTIONAL` for `HIERARHICAL` attributes, dictionary will maintain parent to children index in memory, that way functions `dictGetDescendants`, `dictGetChildren` will not create temporary index per query.

+* Improve performance and memory usage for select of subset of columns for formats Native, Protobuf, CapnProto, JSONEachRow, TSKV, all formats with suffixes WithNames/WithNamesAndTypes. Previously while selecting only subset of columns from files in these formats all columns were read and stored in memory. Now only required columns are read. This PR enables setting `input_format_skip_unknown_fields` by default, because otherwise in case of select of subset of columns exception will be thrown.

+* Improve sort performance by single column. [#37195](https://github.com/ClickHouse/ClickHouse/pull/37195) ([Maksim Kita](https://github.com/kitaisreal)).
+* Support multi disks for caching hive files. [#37279](https://github.com/ClickHouse/ClickHouse/pull/37279) ([lgbo](https://github.com/lgbo-ustc)).
+* Improved performance on array norm and distance functions 2x-4x times. [#37394](https://github.com/ClickHouse/ClickHouse/pull/37394) ([Alexander Gololobov](https://github.com/davenger)).
+* Improve performance of number comparison functions using dynamic dispatch. [#37399](https://github.com/ClickHouse/ClickHouse/pull/37399) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of ORDER BY with LIMIT. [#37481](https://github.com/ClickHouse/ClickHouse/pull/37481) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of `hasAll` function using dynamic dispatch infrastructure. [#37484](https://github.com/ClickHouse/ClickHouse/pull/37484) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of `greatCircleAngle`, `greatCircleDistance`, `geoDistance` functions. [#37524](https://github.com/ClickHouse/ClickHouse/pull/37524) ([Maksim Kita](https://github.com/kitaisreal)).
+* Optimized the internal caching of re2 patterns which occur e.g. in LIKE and MATCH functions. [#37544](https://github.com/ClickHouse/ClickHouse/pull/37544) ([Robert Schulze](https://github.com/rschu1ze)).
+* Improve filter bitmask generator function all in one with avx512 instructions. [#37588](https://github.com/ClickHouse/ClickHouse/pull/37588) ([yaqi-zhao](https://github.com/yaqi-zhao)).
+* Improved performance of aggregation in case, when sparse columns (can be enabled by experimental setting `ratio_of_defaults_for_sparse_serialization` in `MergeTree` tables) are used as arguments in aggregate functions. [#37617](https://github.com/ClickHouse/ClickHouse/pull/37617) ([Anton Popov](https://github.com/CurtizJ)).
+* Optimize function `COALESCE` with two arguments. [#37666](https://github.com/ClickHouse/ClickHouse/pull/37666) ([Anton Popov](https://github.com/CurtizJ)).
+* Replace `multiIf` to `if` in case when `multiIf` has only one condition, because function `if` is more performant. [#37695](https://github.com/ClickHouse/ClickHouse/pull/37695) ([Anton Popov](https://github.com/CurtizJ)).
+* Aggregates state destruction now may be posted on a thread pool. For queries with LIMIT and big state it provides significant speedup, e.g. `select uniq(number) from numbers_mt(1e7) group by number limit 100` became around 2.5x faster. [#37855](https://github.com/ClickHouse/ClickHouse/pull/37855) ([Nikita Taranov](https://github.com/nickitat)).
+* Improve performance of single column sorting using sorting queue specializations. [#37990](https://github.com/ClickHouse/ClickHouse/pull/37990) ([Maksim Kita](https://github.com/kitaisreal)).
+* Fix excessive CPU usage in background when there are a lot of tables. [#38028](https://github.com/ClickHouse/ClickHouse/pull/38028) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improve performance of `not` function using dynamic dispatch. [#38058](https://github.com/ClickHouse/ClickHouse/pull/38058) ([Maksim Kita](https://github.com/kitaisreal)).
+* Added numerous NEON accelerated paths for main libraries. [#38093](https://github.com/ClickHouse/ClickHouse/pull/38093) ([Daniel Kutenin](https://github.com/danlark1)).
+
+#### Improvement
+* Add separate CLUSTER grant (and `access_control_improvements.on_cluster_queries_require_cluster_grant` configuration directive, for backward compatibility, default to `false`). [#35767](https://github.com/ClickHouse/ClickHouse/pull/35767) ([Azat Khuzhin](https://github.com/azat)).
+* Add self extracting executable [#34755](https://github.com/ClickHouse/ClickHouse/issues/34755). [#35775](https://github.com/ClickHouse/ClickHouse/pull/35775) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
+* Added support for schema inference for `hdfsCluster`. [#35812](https://github.com/ClickHouse/ClickHouse/pull/35812) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add feature disks( ls - list files on disk, C - set config file, list-disks - list disks names, disk - set disk for work by name, help - produce help message copy - copy data on disk containing at `from_path` to `to_path` link - Create hardlink on disk from `from_path` to `to_path` list - List files on disk move - Move file or directory on disk from `from_path` to `to_path` read - read File on disk `from_path` to `to_path` or to stdout remove - Remove file or directory on disk with all children. write - Write File on disk`from_path` or stdin to `to_path`). [#36060](https://github.com/ClickHouse/ClickHouse/pull/36060) ([Artyom Yurkov](https://github.com/Varinara)).
+* Implement `least_used` load balancing algorithm for disks inside volume (multi disk configuration). [#36686](https://github.com/ClickHouse/ClickHouse/pull/36686) ([Azat Khuzhin](https://github.com/azat)).
+* - Modify the HTTP Endpoint to return the full stats under the `X-ClickHouse-Summary` header when `send_progress_in_http_headers=0` (before it would return all zeros). - Modify the HTTP Endpoint to return `X-ClickHouse-Exception-Code` header when progress has been sent before (`send_progress_in_http_headers=1`) - Modify the HTTP Endpoint to return `HTTP_REQUEST_TIMEOUT` (408) instead of `HTTP_INTERNAL_SERVER_ERROR` (500) on `TIMEOUT_EXCEEDED` errors. [#36884](https://github.com/ClickHouse/ClickHouse/pull/36884) ([Raúl Marín](https://github.com/Algunenano)).
+* Allow a user to inspect grants from granted roles. [#36941](https://github.com/ClickHouse/ClickHouse/pull/36941) ([nvartolomei](https://github.com/nvartolomei)).
+* Do not calculate an integral numerically but use CDF functions instead. This will speed up execution and will increase the precision. This fixes [#36714](https://github.com/ClickHouse/ClickHouse/issues/36714). [#36953](https://github.com/ClickHouse/ClickHouse/pull/36953) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add default implementation for Nothing in functions. Now most of the functions will return column with type Nothing in case one of it's arguments is Nothing. It also solves problem with functions like arrayMap/arrayFilter and similar when they have empty array as an argument. Previously queries like `select arrayMap(x -> 2 * x, []);` failed because function inside lambda cannot work with type `Nothing`, now such queries return empty array with type `Array(Nothing)`. Also add support for arrays of nullable types in functions like arrayFilter/arrayFill. Previously, queries like `select arrayFilter(x -> x % 2, [1, NULL])` failed, now they work (if the result of lambda is NULL, then this value won't be included in the result). Closes [#37000](https://github.com/ClickHouse/ClickHouse/issues/37000). [#37048](https://github.com/ClickHouse/ClickHouse/pull/37048) ([Kruglov Pavel](https://github.com/Avogar)).
+* Now if a shard has local replica we create a local plan and a plan to read from all remote replicas. They have shared initiator which coordinates reading. [#37204](https://github.com/ClickHouse/ClickHouse/pull/37204) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* In function: CompressedWriteBuffer::nextImpl(), there is an unnecessary write-copy step that would happen frequently during inserting data. Below shows the differentiation with this patch: - Before: 1. Compress "working_buffer" into "compressed_buffer" 2. write-copy into "out" - After: Directly Compress "working_buffer" into "out". [#37242](https://github.com/ClickHouse/ClickHouse/pull/37242) ([jasperzhu](https://github.com/jinjunzh)).
+* Support non-constant SQL functions (NOT) (I)LIKE and MATCH. [#37251](https://github.com/ClickHouse/ClickHouse/pull/37251) ([Robert Schulze](https://github.com/rschu1ze)).
+* Client will try every IP address returned by DNS resolution until successful connection. [#37273](https://github.com/ClickHouse/ClickHouse/pull/37273) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* - Do no longer abort server startup if configuration option "mark_cache_size" is not explicitly set. [#37326](https://github.com/ClickHouse/ClickHouse/pull/37326) ([Robert Schulze](https://github.com/rschu1ze)).
+* Allow to use String type instead of Binary in Arrow/Parquet/ORC formats. This PR introduces 3 new settings for it: `output_format_arrow_string_as_string`, `output_format_parquet_string_as_string`, `output_format_orc_string_as_string`. Default value for all settings is `false`. [#37327](https://github.com/ClickHouse/ClickHouse/pull/37327) ([Kruglov Pavel](https://github.com/Avogar)).
+* Apply setting `input_format_max_rows_to_read_for_schema_inference` for all read rows in total from all files in globs. Previously setting `input_format_max_rows_to_read_for_schema_inference` was applied for each file in glob separately and in case of huge number of nulls we could read first `input_format_max_rows_to_read_for_schema_inference` rows from each file and get nothing. Also increase default value for this setting to 25000. [#37332](https://github.com/ClickHouse/ClickHouse/pull/37332) ([Kruglov Pavel](https://github.com/Avogar)).
+* allows providing `NULL`/`NOT NULL` right after type in column declaration. [#37337](https://github.com/ClickHouse/ClickHouse/pull/37337) ([Igor Nikonov](https://github.com/devcrafter)).
+* optimize file segment PARTIALLY_DOWNLOADED get read buffer. [#37338](https://github.com/ClickHouse/ClickHouse/pull/37338) ([xiedeyantu](https://github.com/xiedeyantu)).
+* Allow to prune the list of files via virtual columns such as `_file` and `_path` when reading from S3. This is for [#37174](https://github.com/ClickHouse/ClickHouse/issues/37174) , [#23494](https://github.com/ClickHouse/ClickHouse/issues/23494). [#37356](https://github.com/ClickHouse/ClickHouse/pull/37356) ([Amos Bird](https://github.com/amosbird)).
+* Try to improve short circuit functions processing to fix problems with stress tests. [#37384](https://github.com/ClickHouse/ClickHouse/pull/37384) ([Kruglov Pavel](https://github.com/Avogar)).
+* Closes [#37395](https://github.com/ClickHouse/ClickHouse/issues/37395). [#37415](https://github.com/ClickHouse/ClickHouse/pull/37415) ([Memo](https://github.com/Joeywzr)).
+* Fix extremely rare deadlock during part fetch in zero-copy replication. Fixes [#37423](https://github.com/ClickHouse/ClickHouse/issues/37423). [#37424](https://github.com/ClickHouse/ClickHouse/pull/37424) ([metahys](https://github.com/metahys)).
+* Don't allow to create storage with unknown data format. [#37450](https://github.com/ClickHouse/ClickHouse/pull/37450) ([Kruglov Pavel](https://github.com/Avogar)).
+* Set `global_memory_usage_overcommit_max_wait_microseconds` default value to 5 seconds. Add info about `OvercommitTracker` to OOM exception message. Add `MemoryOvercommitWaitTimeMicroseconds` profile event. [#37460](https://github.com/ClickHouse/ClickHouse/pull/37460) ([Dmitry Novik](https://github.com/novikd)).
+* Play UI: Keep controls in place when the page is scrolled horizontally. This makes edits comfortable even if the table is wide and it was scrolled far to the right. The feature proposed by Maksym Tereshchenko from CaspianDB. [#37470](https://github.com/ClickHouse/ClickHouse/pull/37470) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Now more filters can be pushed down for join. [#37472](https://github.com/ClickHouse/ClickHouse/pull/37472) ([Amos Bird](https://github.com/amosbird)).
+* Modify query div in play.html to be extendable beyond 20% height. In case of very long queries it is helpful to extend the textarea element, only today, since the div is fixed height, the extended textarea hides the data div underneath. With this fix, extending the textarea element will push the data div down/up such the extended textarea won't hide it. Also, keeps query box width 100% even when the user adjusting the size of the query textarea. [#37488](https://github.com/ClickHouse/ClickHouse/pull/37488) ([guyco87](https://github.com/guyco87)).

+* Currently clickhouse directly downloads all remote files to the local cache (even if they are only read once), which will frequently cause IO of the local hard disk. In some scenarios, these IOs may not be necessary and may easily cause negative optimization. As shown in the figure below, when we run SSB Q1-Q4, the performance of the cache has caused negative optimization. [#37516](https://github.com/ClickHouse/ClickHouse/pull/37516) ([Han Shukai](https://github.com/KinderRiven)).
+* Added `ProfileEvents` for introspection of type of written (inserted or merged) parts (`Inserted{Wide/Compact/InMemory}Parts`, `MergedInto{Wide/Compact/InMemory}Parts`. Added column `part_type` to `system.part_log`. Resolves [#37495](https://github.com/ClickHouse/ClickHouse/issues/37495). [#37536](https://github.com/ClickHouse/ClickHouse/pull/37536) ([Anton Popov](https://github.com/CurtizJ)).
+* clickhouse-keeper improvement: move broken logs to a timestamped folder. [#37565](https://github.com/ClickHouse/ClickHouse/pull/37565) ([Antonio Andelic](https://github.com/antonio2368)).
+* Do not write expired columns by TTL after subsequent merges (before only first merge/optimize of the part will not write expired by TTL columns, all other will do). [#37570](https://github.com/ClickHouse/ClickHouse/pull/37570) ([Azat Khuzhin](https://github.com/azat)).
+* More precise result of the `dumpColumnStructure` miscellaneous function in presence of LowCardinality or Sparse columns. In previous versions, these functions were converting the argument to a full column before returning the result. This is needed to provide an answer in [#6935](https://github.com/ClickHouse/ClickHouse/issues/6935). [#37633](https://github.com/ClickHouse/ClickHouse/pull/37633) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* keeper: store only unique session IDs for watches. [#37641](https://github.com/ClickHouse/ClickHouse/pull/37641) ([Azat Khuzhin](https://github.com/azat)).
+* Fix possible "Cannot write to finalized buffer". [#37645](https://github.com/ClickHouse/ClickHouse/pull/37645) ([Azat Khuzhin](https://github.com/azat)).
+* Add setting `support_batch_delete` for `DiskS3` to disable multiobject delete calls, which Google Cloud Storage doesn't support. [#37659](https://github.com/ClickHouse/ClickHouse/pull/37659) ([Fred Wulff](https://github.com/frew)).
+* Support types with non-standard defaults in ROLLUP, CUBE, GROUPING SETS. Closes [#37360](https://github.com/ClickHouse/ClickHouse/issues/37360). [#37667](https://github.com/ClickHouse/ClickHouse/pull/37667) ([Dmitry Novik](https://github.com/novikd)).
+* Add an option to disable connection pooling in ODBC bridge. [#37705](https://github.com/ClickHouse/ClickHouse/pull/37705) ([Anton Kozlov](https://github.com/tonickkozlov)).
+* ... LIKE patterns with trailing escape symbol ('\\') are now disallowed (as mandated by the SQL standard). [#37764](https://github.com/ClickHouse/ClickHouse/pull/37764) ([Robert Schulze](https://github.com/rschu1ze)).
+* Fix stacktraces collection on ARM. Closes [#37044](https://github.com/ClickHouse/ClickHouse/issues/37044). Closes [#15638](https://github.com/ClickHouse/ClickHouse/issues/15638). [#37797](https://github.com/ClickHouse/ClickHouse/pull/37797) ([Maksim Kita](https://github.com/kitaisreal)).

+* Expose BoringSSL version related info in the `system.build_options` table. [#37850](https://github.com/ClickHouse/ClickHouse/pull/37850) ([Bharat Nallan](https://github.com/bharatnc)).
+* **Description** Limiting the maximum cache usage per query can effectively prevent cache pool contamination. [Related Issues](https://github.com/ClickHouse/ClickHouse/issues/28961). [#37859](https://github.com/ClickHouse/ClickHouse/pull/37859) ([Han Shukai](https://github.com/KinderRiven)).
+* Now clickhouse-server removes `delete_tmp` directories on server start. Fixes [#26503](https://github.com/ClickHouse/ClickHouse/issues/26503). [#37906](https://github.com/ClickHouse/ClickHouse/pull/37906) ([alesapin](https://github.com/alesapin)).

+* Now in MergeTree table engines family failed-to-move parts will be removed instantly. [#37994](https://github.com/ClickHouse/ClickHouse/pull/37994) ([alesapin](https://github.com/alesapin)).
+* Now if setting `always_fetch_merged_part` is enabled for ReplicatedMergeTree merges will try to find parts on other replicas rarely with smaller load for [Zoo]Keeper. [#37995](https://github.com/ClickHouse/ClickHouse/pull/37995) ([alesapin](https://github.com/alesapin)).
+* Add implicit grants with grant option too. For example `GRANT CREATE TABLE ON test.* TO A WITH GRANT OPTION` now allows `A` to execute `GRANT CREATE VIEW ON test.* TO B`. [#38017](https://github.com/ClickHouse/ClickHouse/pull/38017) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Do not display `-0.0` CPU time in clickhouse-client. It can appear due to rounding errors. This closes [#38003](https://github.com/ClickHouse/ClickHouse/issues/38003). This closes [#38038](https://github.com/ClickHouse/ClickHouse/issues/38038). [#38064](https://github.com/ClickHouse/ClickHouse/pull/38064) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

 ## Adding new third-party libraries and maintaining patches in third-party libraries {#adding-third-party-libraries}
 
 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.
-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).
+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).
 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.
 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.

 *HINT*: you could add a database name in front of `table_name` as well. E.g. `db_name.table_name`

 If the local set of data differs too much from the expected one, a safety mechanism is triggered. The server enters this in the log and refuses to launch. The reason for this is that this case may indicate a configuration error, such as if a replica on a shard was accidentally configured like a replica on a different shard. However, the thresholds for this mechanism are set fairly low, and this situation might occur during normal failure recovery.

 Cluster configuration can be dynamically configured but there are some limitations. Reconfiguration relies on Raft also
 so to add/remove a node from the cluster you need to have a quorum. If you lose too many nodes in your cluster at the same time without any chance
 of starting them again, Raft will stop working and not allow you to reconfigure your cluster using the conventional way.
 
-Nevertheless, Clickhouse Keeper has a recovery mode which allows you to forcefully reconfigure your cluster with only 1 node.
+Nevertheless, ClickHouse Keeper has a recovery mode which allows you to forcefully reconfigure your cluster with only 1 node.
 This should be done only as your last resort if you cannot start your nodes again, or start a new instance on the same endpoint.

 -   `Delta(delta_bytes)` — Compression approach in which raw values are replaced by the difference of two neighboring values, except for the first value that stays unchanged. Up to `delta_bytes` are used for storing delta values, so `delta_bytes` is the maximum size of raw values. Possible `delta_bytes` values: 1, 2, 4, 8. The default value for `delta_bytes` is `sizeof(type)` if equal to 1, 2, 4, or 8. In all other cases, it’s 1.
 -   `DoubleDelta` — Calculates delta of deltas and writes it in compact binary form. Optimal compression rates are achieved for monotonic sequences with a constant stride, such as time series data. Can be used with any fixed-width type. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. Uses 1 extra bit for 32-byte deltas: 5-bit prefixes instead of 4-bit prefixes. For additional information, see Compressing Time Stamps in [Gorilla: A Fast, Scalable, In-Memory Time Series Database](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
 -   `Gorilla` — Calculates XOR between current and previous value and writes it in compact binary form. Efficient when storing a series of floating point values that change slowly, because the best compression rate is achieved when neighboring values are binary equal. Implements the algorithm used in Gorilla TSDB, extending it to support 64-bit types. For additional information, see Compressing Values in [Gorilla: A Fast, Scalable, In-Memory Time Series Database](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf).
+-   `FPC` - Repeatedly predicts the next floating point value in the sequence using the better of two predictors, then XORs the actual with the predicted value, and leading-zero compresses the result. Similar to Gorilla, this is efficient when storing a series of floating point values that change slowly. For 64-bit values (double), FPC is faster than Gorilla, for 32-bit values your mileage may vary. For a detailed description of the algorithm see [High Throughput Compression of Double-Precision Floating-Point Data](https://userweb.cs.txstate.edu/~burtscher/papers/dcc07a.pdf).
 -   `T64` — Compression approach that crops unused high bits of values in integer data types (including `Enum`, `Date` and `DateTime`). At each step of its algorithm, codec takes a block of 64 values, puts them into 64x64 bit matrix, transposes it, crops the unused bits of values and returns the rest as a sequence. Unused bits are the bits, that do not differ between maximum and minimum values in the whole data part for which the compression is used.
 
 `DoubleDelta` and `Gorilla` codecs are used in Gorilla TSDB as the components of its compressing algorithm. Gorilla approach is effective in scenarios when there is a sequence of slowly changing values with their timestamps. Timestamps are effectively compressed by the `DoubleDelta` codec, and values are effectively compressed by the `Gorilla` codec. For example, to get an effectively stored table, you can create it in the following configuration:

+## GROUPING SETS modifier
+
+This is the most general modifier.
+This modifier allows to manually specify several aggregation key sets (grouping sets).
+Aggregation is performed separately for each grouping set, after that all results are combined.
+If a column is not presented in a grouping set, it's filled with a default value.
+
+In other words, modifiers described above can be represented via `GROUPING SETS`.
+Despite the fact that queries with `ROLLUP`, `CUBE` and `GROUPING SETS` modifiers are syntactically equal, they may have different performance.
+When `GROUPING SETS` try to execute everything in parallel, `ROLLUP` and `CUBE` are executing the final merging of the aggregates in a single thread.
+
+In the situation when source columns contain default values, it might be hard to distinguish if a row is a part of the aggregation which uses those columns as keys or not.
+To solve this problem `GROUPING` function must be used.

By default, aggregation is done in memory using a hash-table. It has 40+ specializations that are chosen automatically depending on “grouping key” data types.

 ClickHouse не удаляет данные в реальном времени, как СУБД [OLTP](https://en.wikipedia.org/wiki/Online_transaction_processing). Больше всего на такое удаление похожи мутации. Они выполняются с помощью запросов `ALTER ... DELETE` или `ALTER ... UPDATE`. В отличие от обычных запросов `DELETE` и `UPDATE`, мутации выполняются асинхронно, в пакетном режиме, не в реальном времени. В остальном после слов `ALTER TABLE` синтаксис обычных запросов и мутаций одинаковый.
 
-`ALTER DELETE` можно использовать для гибкого удаления устаревших данных. Если вам нужно делать это регулярно, единственный недостаток такого подхода будет заключаться в том, что потребуется внешняя система для запуска запроса. Кроме того, могут возникнуть некоторые проблемы с производительностью, поскольку мутации перезаписывают целые куски данных если в них содержится хотя бы одна строка, которую нужно удалить.
