# 2023 Changelog
|
||||
|
||||
### ClickHouse release 23.9, 2023-09-28
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Remove the `status_info` configuration option and dictionaries status from the default Prometheus handler. [#54090](https://github.com/ClickHouse/ClickHouse/pull/54090) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* The experimental parts metadata cache is removed from the codebase. [#54215](https://github.com/ClickHouse/ClickHouse/pull/54215) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Disable setting `input_format_json_try_infer_numbers_from_strings` by default, so we don't try to infer numbers from strings in JSON formats by default to avoid possible parsing errors when sample data contains strings that looks like a number. [#55099](https://github.com/ClickHouse/ClickHouse/pull/55099) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### New Feature
|
||||
* Improve schema inference from JSON formats: 1) Now it's possible to infer named Tuples from JSON objects without experimantal JSON type under a setting `input_format_json_try_infer_named_tuples_from_objects` in JSON formats. Previously without experimantal type JSON we could only infer JSON objects as Strings or Maps, now we can infer named Tuple. Resulting Tuple type will conain all keys of objects that were read in data sample during schema inference. It can be useful for reading structured JSON data without sparse objects. The setting is enabled by default. 2) Allow parsing JSON array into a column with type String under setting `input_format_json_read_arrays_as_strings`. It can help reading arrays with values with different types. 3) Allow to use type String for JSON keys with unkown types (`null`/`[]`/`{}`) in sample data under setting `input_format_json_infer_incomplete_types_as_strings`. Now in JSON formats we can read any value into String column and we can avoid getting error `Cannot determine type for column 'column_name' by first 25000 rows of data, most likely this column contains only Nulls or empty Arrays/Maps` during schema inference by using type String for unknown types, so the data will be read successfully. [#54427](https://github.com/ClickHouse/ClickHouse/pull/54427) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Added IO scheduling support for remote disks. Storage configuration for disk types `s3`, `s3_plain`, `hdfs` and `azure_blob_storage` can now contain `read_resource` and `write_resource` elements holding resource names. Scheduling policies for these resources can be configured in a separate server configuration section `resources`. Queries can be marked using setting `workload` and classified using server configuration section `workload_classifiers` to achieve diverse resource scheduling goals. More details in [the docs](https://clickhouse.com/docs/en/operations/workload-scheduling). [#47009](https://github.com/ClickHouse/ClickHouse/pull/47009) ([Sergei Trifonov](https://github.com/serxa)). Added "bandwidth_limit" IO scheduling node type. It allows you to specify `max_speed` and `max_burst` constraints on traffic passing though this node. [#54618](https://github.com/ClickHouse/ClickHouse/pull/54618) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Added new type of authentication based on SSH keys. It works only for the native TCP protocol. [#41109](https://github.com/ClickHouse/ClickHouse/pull/41109) ([George Gamezardashvili](https://github.com/InfJoker)).
|
||||
* Added a new column `_block_number` for MergeTree tables. [#44532](https://github.com/ClickHouse/ClickHouse/issues/44532). [#47532](https://github.com/ClickHouse/ClickHouse/pull/47532) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
|
||||
* Add `IF EMPTY` clause for `DROP TABLE` queries. [#48915](https://github.com/ClickHouse/ClickHouse/pull/48915) ([Pavel Novitskiy](https://github.com/pnovitskiy)).
|
||||
* SQL functions `toString(datetime, timezone)` and `formatDateTime(datetime, format, timezone)` now support non-constant timezone arguments. [#53680](https://github.com/ClickHouse/ClickHouse/pull/53680) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Add support for `ALTER TABLE MODIFY COMMENT`. Note: something similar was added by an external contributor a long time ago, but the feature did not work at all and only confused users. This closes [#36377](https://github.com/ClickHouse/ClickHouse/issues/36377). [#51304](https://github.com/ClickHouse/ClickHouse/pull/51304) ([Alexey Milovidov](https://github.com/alexey-milovidov)). Note: this command does not propagate between replicas, so the replicas of a table could have different comments.
|
||||
* Added `GCD` a.k.a. "greatest common denominator" as a new data compression codec. The codec computes the GCD of all column values, and then divides each value by the GCD. The GCD codec is a data preparation codec (similar to Delta and DoubleDelta) and cannot be used stand-alone. It works with data integer, decimal and date/time type. A viable use case for the GCD codec are column values that change (increase/decrease) in multiples of the GCD, e.g. 24 - 28 - 16 - 24 - 8 - 24 (assuming GCD = 4). [#53149](https://github.com/ClickHouse/ClickHouse/pull/53149) ([Alexander Nam](https://github.com/seshWCS)).
|
||||
* Two new type aliases `DECIMAL(P)` (as shortcut for `DECIMAL(P, 0)` and `DECIMAL` (as shortcut for `DECIMAL(10, 0)`) were added. This makes ClickHouse more compatible with MySQL's SQL dialect. [#53328](https://github.com/ClickHouse/ClickHouse/pull/53328) ([Val Doroshchuk](https://github.com/valbok)).
|
||||
* Added a new system log table `backup_log` to track all `BACKUP` and `RESTORE` operations. [#53638](https://github.com/ClickHouse/ClickHouse/pull/53638) ([Victor Krasnov](https://github.com/sirvickr)).
|
||||
* Added a format setting `output_format_markdown_escape_special_characters` (default: false). The setting controls whether special characters like `!`, `#`, `$` etc. are escaped (i.e. prefixed by a backslash) in the `Markdown` output format. [#53860](https://github.com/ClickHouse/ClickHouse/pull/53860) ([irenjj](https://github.com/irenjj)).
|
||||
* Add function `decodeHTMLComponent`. [#54097](https://github.com/ClickHouse/ClickHouse/pull/54097) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Added `peak_threads_usage` to query_log table. [#54335](https://github.com/ClickHouse/ClickHouse/pull/54335) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
|
||||
* Add `SHOW FUNCTIONS` support to clickhouse-client. [#54337](https://github.com/ClickHouse/ClickHouse/pull/54337) ([Julia Kartseva](https://github.com/wat-ze-hex)).
|
||||
* Added function `toDaysSinceYearZero` with alias `TO_DAYS` (for compatibility with MySQL) which returns the number of days passed since `0001-01-01` (in Proleptic Gregorian Calendar). [#54479](https://github.com/ClickHouse/ClickHouse/pull/54479) ([Robert Schulze](https://github.com/rschu1ze)). Function `toDaysSinceYearZero()` now supports arguments of type `DateTime` and `DateTime64`. [#54856](https://github.com/ClickHouse/ClickHouse/pull/54856) ([Serge Klochkov](https://github.com/slvrtrn)).
|
||||
* Added functions `YYYYMMDDtoDate`, `YYYYMMDDtoDate32`, `YYYYMMDDhhmmssToDateTime` and `YYYYMMDDhhmmssToDateTime64`. They convert a date or date with time encoded as integer (e.g. 20230911) into a native date or date with time. As such, they provide the opposite functionality of existing functions `YYYYMMDDToDate`, `YYYYMMDDToDateTime`, `YYYYMMDDhhmmddToDateTime`, `YYYYMMDDhhmmddToDateTime64`. [#54509](https://github.com/ClickHouse/ClickHouse/pull/54509) ([Quanfa Fu](https://github.com/dentiscalprum)) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Add several string distance functions, including `byteHammingDistance`, `editDistance`. [#54935](https://github.com/ClickHouse/ClickHouse/pull/54935) ([flynn](https://github.com/ucasfl)).
|
||||
* Allow specifying the expiration date and, optionally, the time for user credentials with `VALID UNTIL datetime` clause. [#51261](https://github.com/ClickHouse/ClickHouse/pull/51261) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Allow S3-style URLs for table functions `s3`, `gcs`, `oss`. URL is automatically converted to HTTP. Example: `'s3://clickhouse-public-datasets/hits.csv'` is converted to `'https://clickhouse-public-datasets.s3.amazonaws.com/hits.csv'`. [#54931](https://github.com/ClickHouse/ClickHouse/pull/54931) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Add new setting `print_pretty_type_names` to print pretty deep nested types like Tuple/Maps/Arrays. [#55095](https://github.com/ClickHouse/ClickHouse/pull/55095) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Speed up reading from S3 by enabling prefetches by default. [#53709](https://github.com/ClickHouse/ClickHouse/pull/53709) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Do not implicitly read PK and version columns in lonely parts if unnecessary for queries with FINAL. [#53919](https://github.com/ClickHouse/ClickHouse/pull/53919) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Optimize group by constant keys. Will optimize queries with group by `_file/_path` after https://github.com/ClickHouse/ClickHouse/pull/53529. [#53549](https://github.com/ClickHouse/ClickHouse/pull/53549) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Improve performance of sorting for `Decimal` columns. Improve performance of insertion into `MergeTree` if ORDER BY contains a `Decimal` column. Improve performance of sorting when data is already sorted or almost sorted. [#35961](https://github.com/ClickHouse/ClickHouse/pull/35961) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Improve performance for huge query analysis. Fixes [#51224](https://github.com/ClickHouse/ClickHouse/issues/51224). [#51469](https://github.com/ClickHouse/ClickHouse/pull/51469) ([frinkr](https://github.com/frinkr)).
|
||||
* An optimization to rewrite `COUNT(DISTINCT ...)` and various `uniq` variants to `count` if it is selected from a subquery with GROUP BY. [#52082](https://github.com/ClickHouse/ClickHouse/pull/52082) [#52645](https://github.com/ClickHouse/ClickHouse/pull/52645) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* Remove manual calls to `mmap/mremap/munmap` and delegate all this work to `jemalloc` - and it slightly improves performance. [#52792](https://github.com/ClickHouse/ClickHouse/pull/52792) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Fixed high in CPU consumption when working with NATS. [#54399](https://github.com/ClickHouse/ClickHouse/pull/54399) ([Vasilev Pyotr](https://github.com/vahpetr)).
|
||||
* Since we use separate instructions for executing `toString()` with datetime argument, it is possible to improve performance a bit for non-datetime arguments and have some parts of the code cleaner. Follows up [#53680](https://github.com/ClickHouse/ClickHouse/issues/53680). [#54443](https://github.com/ClickHouse/ClickHouse/pull/54443) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).

* Instead of serializing json elements into a `std::stringstream`, this PR try to put the serialization result into `ColumnString` direclty. [#54613](https://github.com/ClickHouse/ClickHouse/pull/54613) ([lgbo](https://github.com/lgbo-ustc)).
|
||||
* Enable ORDER BY optimization for reading data in corresponding order from a MergeTree table in case that the table is behind a view. [#54628](https://github.com/ClickHouse/ClickHouse/pull/54628) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Improve JSON SQL functions by reusing `GeneratorJSONPath` and removing several shared pointers. [#54735](https://github.com/ClickHouse/ClickHouse/pull/54735) ([lgbo](https://github.com/lgbo-ustc)).
|
||||
* Keeper tries to batch flush requests for better performance. [#53049](https://github.com/ClickHouse/ClickHouse/pull/53049) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Now `clickhouse-client` processes files in parallel in case of `INFILE 'glob_expression'`. Closes [#54218](https://github.com/ClickHouse/ClickHouse/issues/54218). [#54533](https://github.com/ClickHouse/ClickHouse/pull/54533) ([Max K.](https://github.com/mkaynov)).
|
||||
* Allow to use primary key for IN function where primary key column types are different from `IN` function right side column types. Example: `SELECT id FROM test_table WHERE id IN (SELECT '5')`. Closes [#48936](https://github.com/ClickHouse/ClickHouse/issues/48936). [#54544](https://github.com/ClickHouse/ClickHouse/pull/54544) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Hash JOIN tries to shrink internal buffers consuming half of maximal available memory (set by `max_bytes_in_join`). [#54584](https://github.com/ClickHouse/ClickHouse/pull/54584) ([vdimir](https://github.com/vdimir)).
|
||||
* Respect `max_block_size` for array join to avoid possible OOM. Close [#54290](https://github.com/ClickHouse/ClickHouse/issues/54290). [#54664](https://github.com/ClickHouse/ClickHouse/pull/54664) ([李扬](https://github.com/taiyang-li)).
|
||||
* Reuse HTTP connections in the `s3` table function. [#54812](https://github.com/ClickHouse/ClickHouse/pull/54812) ([Michael Kolupaev](https://github.com/al13n321)).
|
||||
* Replace the linear search in `MergeTreeRangeReader::Stream::ceilRowsToCompleteGranules` with a binary search. [#54869](https://github.com/ClickHouse/ClickHouse/pull/54869) ([usurai](https://github.com/usurai)).
|
||||
|
||||
#### Experimental Feature
|
||||
* The creation of `Annoy` indexes can now be parallelized using setting `max_threads_for_annoy_index_creation`. [#54047](https://github.com/ClickHouse/ClickHouse/pull/54047) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Parallel replicas over distributed don't read from all replicas [#54199](https://github.com/ClickHouse/ClickHouse/pull/54199) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
|
||||
#### Improvement
|
||||
* Allow to replace long names of files of columns in `MergeTree` data parts to hashes of names. It helps to avoid `File name too long` error in some cases. [#50612](https://github.com/ClickHouse/ClickHouse/pull/50612) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Parse data in `JSON` format as `JSONEachRow` if failed to parse metadata. It will allow to read files with `.json` extension even if real format is JSONEachRow. Closes [#45740](https://github.com/ClickHouse/ClickHouse/issues/45740). [#54405](https://github.com/ClickHouse/ClickHouse/pull/54405) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Output valid JSON/XML on excetpion during HTTP query execution. Add setting `http_write_exception_in_output_format` to enable/disable this behaviour (enabled by default). [#52853](https://github.com/ClickHouse/ClickHouse/pull/52853) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* View `information_schema.tables` now has a new field `data_length` which shows the approximate size of the data on disk. Required to run queries generated by Amazon QuickSight. [#55037](https://github.com/ClickHouse/ClickHouse/pull/55037) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* The MySQL interface gained a minimal implementation of prepared statements, just enough to allow a connection from Tableau Online to ClickHouse via the MySQL connector. [#54115](https://github.com/ClickHouse/ClickHouse/pull/54115) ([Serge Klochkov](https://github.com/slvrtrn)). Please note: the prepared statements implementation is pretty minimal, we do not support arguments binding yet, it is not required in this particular Tableau online use case. It will be implemented as a follow-up if necessary after extensive testing of Tableau Online in case we discover issues.
|
||||
* Support case-insensitive and dot-all matching modes in `regexp_tree` dictionaries. [#50906](https://github.com/ClickHouse/ClickHouse/pull/50906) ([Johann Gan](https://github.com/johanngan)).
|
||||
* Keeper improvement: Add a `createIfNotExists` Keeper command. [#48855](https://github.com/ClickHouse/ClickHouse/pull/48855) ([Konstantin Bogdanov](https://github.com/thevar1able)).
|
||||
* More precise integer type inference, fix [#51236](https://github.com/ClickHouse/ClickHouse/issues/51236). [#53003](https://github.com/ClickHouse/ClickHouse/pull/53003) ([Chen768959](https://github.com/Chen768959)).
|
||||
* Introduced resolving of charsets in the string literals for MaterializedMySQL. [#53220](https://github.com/ClickHouse/ClickHouse/pull/53220) ([Val Doroshchuk](https://github.com/valbok)).
|
||||
* Fix a subtle issue with a rarely used `EmbeddedRocksDB` table engine in an extremely rare scenario: sometimes the `EmbeddedRocksDB` table engine does not close files correctly in NFS after running `DROP TABLE`. [#53502](https://github.com/ClickHouse/ClickHouse/pull/53502) ([Mingliang Pan](https://github.com/liangliangpan)).
|
||||
* `RESTORE TABLE ON CLUSTER` must create replicated tables with a matching UUID on hosts. Otherwise the macro `{uuid}` in ZooKeeper path can't work correctly after RESTORE. This PR implements that. [#53765](https://github.com/ClickHouse/ClickHouse/pull/53765) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Added restore setting `restore_broken_parts_as_detached`: if it's true the RESTORE process won't stop on broken parts while restoring, instead all the broken parts will be copied to the `detached` folder with the prefix `broken-from-backup'. If it's false the RESTORE process will stop on the first broken part (if any). The default value is false. [#53877](https://github.com/ClickHouse/ClickHouse/pull/53877) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Add `elapsed_ns` field to HTTP headers X-ClickHouse-Progress and X-ClickHouse-Summary. [#54179](https://github.com/ClickHouse/ClickHouse/pull/54179) ([joelynch](https://github.com/joelynch)).
|
||||
* Implementation of `reconfig` (https://github.com/ClickHouse/ClickHouse/pull/49450), `sync`, and `exists` commands for keeper-client. [#54201](https://github.com/ClickHouse/ClickHouse/pull/54201) ([pufit](https://github.com/pufit)).
|
||||
* `clickhouse-local` and `clickhouse-client` now allow to specify the `--query` parameter multiple times, e.g. `./clickhouse-client --query "SELECT 1" --query "SELECT 2"`. This syntax is slightly more intuitive than `./clickhouse-client --multiquery "SELECT 1;S ELECT 2"`, a bit easier to script (e.g. `queries.push_back('--query "$q"')`) and more consistent with the behavior of existing parameter `--queries-file` (e.g. `./clickhouse client --queries-file queries1.sql --queries-file queries2.sql`). [#54249](https://github.com/ClickHouse/ClickHouse/pull/54249) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Add sub-second precision to `formatReadableTimeDelta`. [#54250](https://github.com/ClickHouse/ClickHouse/pull/54250) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* Enable `allow_remove_stale_moving_parts` by default. [#54260](https://github.com/ClickHouse/ClickHouse/pull/54260) ([vdimir](https://github.com/vdimir)).
|
||||
* Fix using count from cache and improve progress bar for reading from archives. [#54271](https://github.com/ClickHouse/ClickHouse/pull/54271) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add support for S3 credentials using SSO. To define a profile to be used with SSO, set `AWS_PROFILE` environment variable. [#54347](https://github.com/ClickHouse/ClickHouse/pull/54347) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Support NULL as default for nested types Array/Tuple/Map for input formats. Closes [#51100](https://github.com/ClickHouse/ClickHouse/issues/51100). [#54351](https://github.com/ClickHouse/ClickHouse/pull/54351) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Allow reading some unusual configuration of chunks from Arrow/Parquet formats. [#54370](https://github.com/ClickHouse/ClickHouse/pull/54370) ([Arthur Passos](https://github.com/arthurpassos)).
|
||||
* Add `STD` alias to `stddevPop` function for MySQL compatibility. Closes [#54274](https://github.com/ClickHouse/ClickHouse/issues/54274). [#54382](https://github.com/ClickHouse/ClickHouse/pull/54382) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Add `addDate` function for compatibility with MySQL and `subDate` for consistency. Reference [#54275](https://github.com/ClickHouse/ClickHouse/issues/54275). [#54400](https://github.com/ClickHouse/ClickHouse/pull/54400) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Support `SAMPLE BY` for views. [#54477](https://github.com/ClickHouse/ClickHouse/pull/54477) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Add `modification_time` into `system.detached_parts`. [#54506](https://github.com/ClickHouse/ClickHouse/pull/54506) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added a setting `splitby_max_substrings_includes_remaining_string` which controls if functions "splitBy*()" with argument "max_substring" > 0 include the remaining string (if any) in the result array (Python/Spark semantics) or not. The default behavior does not change. [#54518](https://github.com/ClickHouse/ClickHouse/pull/54518) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Better integer types inference for `Int64`/`UInt64` fields. Continuation of [#53003](https://github.com/ClickHouse/ClickHouse/pull/53003). Now it works also for nested types like Arrays of Arrays and for functions like `map/tuple`. Issue: [#51236](https://github.com/ClickHouse/ClickHouse/issues/51236). [#54553](https://github.com/ClickHouse/ClickHouse/pull/54553) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Added array operations for multiplying, dividing and modulo on scalar. Works in each way, for example `5 * [5, 5]` and `[5, 5] * 5` - both cases are possible. [#54608](https://github.com/ClickHouse/ClickHouse/pull/54608) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Add optional `version` argument to `rm` command in `keeper-client` to support safer deletes. [#54708](https://github.com/ClickHouse/ClickHouse/pull/54708) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
|
||||
* Disable killing the server by systemd (that may lead to data loss when using Buffer tables). [#54744](https://github.com/ClickHouse/ClickHouse/pull/54744) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added field `is_deterministic` to system table `system.functions` which indicates whether the result of a function is stable between two invocations (given exactly the same inputs) or not. [#54766](https://github.com/ClickHouse/ClickHouse/pull/54766) [#55035](https://github.com/ClickHouse/ClickHouse/pull/55035) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Made the views in schema `information_schema` more compatible with the equivalent views in MySQL (i.e. modified and extended them) up to a point where Tableau Online is able to connect to ClickHouse. More specifically: 1. The type of field `information_schema.tables.table_type` changed from Enum8 to String. 2. Added fields `table_comment` and `table_collation` to view `information_schema.table`. 3. Added views `information_schema.key_column_usage` and `referential_constraints`. 4. Replaced uppercase aliases in `information_schema` views with concrete uppercase columns. [#54773](https://github.com/ClickHouse/ClickHouse/pull/54773) ([Serge Klochkov](https://github.com/slvrtrn)).
|
||||
* The query cache now returns an error if the user tries to cache the result of a query with a non-deterministic function such as `now`, `randomString` and `dictGet`. Compared to the previous behavior (silently don't cache the result), this reduces confusion and surprise for users. [#54801](https://github.com/ClickHouse/ClickHouse/pull/54801) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Forbid special columns like materialized/ephemeral/alias for `file`/`s3`/`url`/... storages, fix insert into ephemeral columns from files. Closes [#53477](https://github.com/ClickHouse/ClickHouse/issues/53477). [#54803](https://github.com/ClickHouse/ClickHouse/pull/54803) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* More configurable collecting metadata for backup. [#54804](https://github.com/ClickHouse/ClickHouse/pull/54804) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* `clickhouse-local`'s log file (if enabled with --server_logs_file flag) will now prefix each line with timestamp, thread id, etc, just like `clickhouse-server`. [#54807](https://github.com/ClickHouse/ClickHouse/pull/54807) ([Michael Kolupaev](https://github.com/al13n321)).
|
||||
* Field `is_obsolete` in the `system.merge_tree_settings` table - it is now 1 for obsolete merge tree settings. Previously, only the description indicated that the setting is obsolete. [#54837](https://github.com/ClickHouse/ClickHouse/pull/54837) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Make it possible to use plural when using interval literals. `INTERVAL 2 HOURS` should be equivalent to `INTERVAL 2 HOUR`. [#54860](https://github.com/ClickHouse/ClickHouse/pull/54860) ([Jordi Villar](https://github.com/jrdi)).
|
||||
* Always allow the creation of a projection with `Nullable` PK. This fixes [#54814](https://github.com/ClickHouse/ClickHouse/issues/54814). [#54895](https://github.com/ClickHouse/ClickHouse/pull/54895) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Retry backup's S3 operations after connection reset failure. [#54900](https://github.com/ClickHouse/ClickHouse/pull/54900) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Make the exception message exact in case of the maximum value of a settings is less than the minimum value. [#54925](https://github.com/ClickHouse/ClickHouse/pull/54925) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
|
||||
* `LIKE`, `match`, and other regular expressions matching functions now allow matching with patterns containing non-UTF-8 substrings by falling back to binary matching. Example: you can use `string LIKE '\xFE\xFF%'` to detect BOM. This closes [#54486](https://github.com/ClickHouse/ClickHouse/issues/54486). [#54942](https://github.com/ClickHouse/ClickHouse/pull/54942) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Added `ContextLockWaitMicroseconds` profile event. [#55029](https://github.com/ClickHouse/ClickHouse/pull/55029) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* The Keeper dynamically adjusts log levels. [#50372](https://github.com/ClickHouse/ClickHouse/pull/50372) ([helifu](https://github.com/helifu)).
|
||||
* Added function `timestamp` for compatibility with MySQL. Closes [#54275](https://github.com/ClickHouse/ClickHouse/issues/54275). [#54639](https://github.com/ClickHouse/ClickHouse/pull/54639) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|
||||
* Bumped the compiler of official and continuous integration builds of ClickHouse from Clang 16 to 17. [#53831](https://github.com/ClickHouse/ClickHouse/pull/53831) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Regenerated tld data for lookups (`tldLookup.generated.cpp`). [#54269](https://github.com/ClickHouse/ClickHouse/pull/54269) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Remove the redundant `clickhouse-keeper-client` symlink. [#54587](https://github.com/ClickHouse/ClickHouse/pull/54587) ([Tomas Barton](https://github.com/deric)).
|
||||
* Use `/usr/bin/env` to resolve bash - now it supports Nix OS. [#54603](https://github.com/ClickHouse/ClickHouse/pull/54603) ([Fionera](https://github.com/fionera)).
|
||||
* CMake added `PROFILE_CPU` option needed to perform `perf record` without using a DWARF call graph. [#54917](https://github.com/ClickHouse/ClickHouse/pull/54917) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* If the linker is different than LLD, stop with a fatal error. [#55036](https://github.com/ClickHouse/ClickHouse/pull/55036) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Replaced the library to handle (encode/decode) base64 values from Turbo-Base64 to aklomp-base64. Both are SIMD-accelerated on x86 and ARM but 1. the license of the latter (BSD-2) is more favorable for ClickHouse, Turbo64 switched in the meantime to GPL-3, 2. with more GitHub stars, aklomp-base64 seems more future-proof, 3. aklomp-base64 has a slightly nicer API (which is arguably subjective), and 4. aklomp-base64 does not require us to hack around bugs (like non-threadsafe initialization). Note: aklomp-base64 rejects unpadded base64 values whereas Turbo-Base64 decodes them on a best-effort basis. RFC-4648 leaves it open whether padding is mandatory or not, but depending on the context this may be a behavioral change to be aware of. [#54119](https://github.com/ClickHouse/ClickHouse/pull/54119) ([Mikhail Koviazin](https://github.com/mkmkme)).
|
||||
|

# 2023 Changelog
|
||||
|
||||
### ClickHouse release v23.9.1.1854-stable (8f9a227de1f) FIXME as compared to v23.8.1.2992-lts (ebc7d9a9f3b)
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Remove the `status_info` configuration option and dictionaries status from the default Prometheus handler. [#54090](https://github.com/ClickHouse/ClickHouse/pull/54090) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* The experimental parts metadata cache is removed from the codebase. [#54215](https://github.com/ClickHouse/ClickHouse/pull/54215) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Disable setting `input_format_json_try_infer_numbers_from_strings` by default, so we don't try to infer numbers from strings in JSON formats by default to avoid possible parsing errors when sample data contains strings that looks like a number. [#55099](https://github.com/ClickHouse/ClickHouse/pull/55099) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### New Feature
|
||||
* Added new type of authentication based on SSH keys. It works only for Native TCP protocol. [#41109](https://github.com/ClickHouse/ClickHouse/pull/41109) ([George Gamezardashvili](https://github.com/InfJoker)).
|
||||
* Added IO Scheduling support for remote disks. Storage configuration for disk types `s3`, `s3_plain`, `hdfs` and `azure_blob_storage` can now contain `read_resource` and `write_resource` elements holding resource names. Scheduling policies for these resources can be configured in a separate server configuration section `resources`. Queries can be marked using setting `workload` and classified using server configuration section `workload_classifiers` to achieve diverse resource scheduling goals. More details in docs/en/operations/workload-scheduling.md. [#47009](https://github.com/ClickHouse/ClickHouse/pull/47009) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Added a new column _block_number resolves [#44532](https://github.com/ClickHouse/ClickHouse/issues/44532). [#47532](https://github.com/ClickHouse/ClickHouse/pull/47532) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
|
||||
* Add options `partial_result_update_duration_ms` and `max_rows_in_partial_result` to show updates of a partial result of output table in real-time during query execution. [#48607](https://github.com/ClickHouse/ClickHouse/pull/48607) ([Alexey Perevyshin](https://github.com/alexX512)).
|
||||
* Support case-insensitive and dot-all matching modes in RegExpTree dictionaries. [#50906](https://github.com/ClickHouse/ClickHouse/pull/50906) ([Johann Gan](https://github.com/johanngan)).
|
||||
* Add support for `ALTER TABLE MODIFY COMMENT`. Note: something similar was added by an external contributor a long time ago, but the feature did not work at all and only confused users. This closes [#36377](https://github.com/ClickHouse/ClickHouse/issues/36377). [#51304](https://github.com/ClickHouse/ClickHouse/pull/51304) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Added "GCD" aka. "greatest common denominator" as a new data compression codec. The codec computes the GCD of all column values, and then divides each value by the GCD. The GCD codec is a data preparation codec (similar to Delta and DoubleDelta) and cannot be used stand-alone. It works with data integer, decimal and date/time type. A viable use case for the GCD codec are column values that change (increase/decrease) in multiples of the GCD, e.g. 24 - 28 - 16 - 24 - 8 - 24 (assuming GCD = 4). [#53149](https://github.com/ClickHouse/ClickHouse/pull/53149) ([Alexander Nam](https://github.com/seshWCS)).
|
||||
* Two new type aliases "DECIMAL(P)" (as shortcut for "DECIMAL(P, 0") and "DECIMAL" (as shortcut for "DECIMAL(10, 0)") were added. This makes ClickHouse more compatible with MySQL's SQL dialect. [#53328](https://github.com/ClickHouse/ClickHouse/pull/53328) ([Val Doroshchuk](https://github.com/valbok)).
|
||||
* Added a new system log table `backup_log` to track all `BACKUP` and `RESTORE` operations. [#53638](https://github.com/ClickHouse/ClickHouse/pull/53638) ([Victor Krasnov](https://github.com/sirvickr)).
|
||||
* Added a format setting "output_format_markdown_escape_special_characters" (default: false). The setting controls whether special characters like "!", "#", "$" etc. are escaped (i.e. prefixed by a backslash) in the "Markdown" output format. [#53860](https://github.com/ClickHouse/ClickHouse/pull/53860) ([irenjj](https://github.com/irenjj)).
|
||||
* Add function `decodeHTMLComponent`. [#54097](https://github.com/ClickHouse/ClickHouse/pull/54097) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Added peak_threads_usage to query_log table. [#54335](https://github.com/ClickHouse/ClickHouse/pull/54335) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
|
||||
* Add SHOW FUNCTIONS support to clickhouse-client. [#54337](https://github.com/ClickHouse/ClickHouse/pull/54337) ([Julia Kartseva](https://github.com/wat-ze-hex)).
|
||||
* This PRs improves schema inference from JSON formats: 1) Now it's possible to infer named Tuples from JSON objects without experimantal JSON type under a setting `input_format_json_try_infer_named_tuples_from_objects` in JSON formats. Previously without experimantal type JSON we could only infer JSON objects as Strings or Maps, now we can infer named Tuple. Resulting Tuple type will conain all keys of objects that were read in data sample during schema inference. It can be useful for reading structured JSON data without sparse objects. The setting is enabled by default. 2) Allow parsing JSON array into a column with type String under setting `input_format_json_read_arrays_as_strings`. It can help reading arrays with values with different types. 3) Allow to use type String for JSON keys with unkown types (`null`/`[]`/`{}`) in sample data under setting `input_format_json_infer_incomplete_types_as_strings`. Now in JSON formats we can read any value into String column and we can avoid getting error `Cannot determine type for column 'column_name' by first 25000 rows of data, most likely this column contains only Nulls or empty Arrays/Maps` during schema inference by using type String for unknown types, so the data will be read successfully. [#54427](https://github.com/ClickHouse/ClickHouse/pull/54427) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Added function "toDaysSinceYearZero" with alias "TO_DAYS()" (for compatibility with MySQL) which returns the number of days passed since 0001-01-01. [#54479](https://github.com/ClickHouse/ClickHouse/pull/54479) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Added functions YYYYMMDDtoDate(), YYYYMMDDtoDate32(), YYYYMMDDhhmmssToDateTime() and YYYYMMDDhhmmssToDateTime64(). They convert a date or date with time encoded as integer (e.g. 20230911) into a native date or date with time. As such, they provide the opposite functionality of existing functions YYYYMMDDToDate(), YYYYMMDDToDateTime(), YYYYMMDDhhmmddToDateTime(), YYYYMMDDhhmmddToDateTime64(). [#54509](https://github.com/ClickHouse/ClickHouse/pull/54509) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Added "bandwidth_limit" IO scheduling node type. It allows you to specify `max_speed` and `max_burst` constraints on traffic passing though this node. More details in docs/en/operations/workload-scheduling.md. [#54618](https://github.com/ClickHouse/ClickHouse/pull/54618) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* Function `toDaysSinceYearZero()` now supports arguments of type `DateTime` and `DateTime64`. [#54856](https://github.com/ClickHouse/ClickHouse/pull/54856) ([Serge Klochkov](https://github.com/slvrtrn)).
|
||||
* Allow S3-style URLs for table functions `s3`, `gcs`, `oss`. URL is automatically converted to HTTP. Example: `'s3://clickhouse-public-datasets/hits.csv'` is converted to `'https://clickhouse-public-datasets.s3.amazonaws.com/hits.csv'`. [#54931](https://github.com/ClickHouse/ClickHouse/pull/54931) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Add several string distance functions, include `byteHammingDistance`, `byteJaccardIndex`, `byteEditDistance`. ### Documentation entry for user-facing changes. [#54935](https://github.com/ClickHouse/ClickHouse/pull/54935) ([flynn](https://github.com/ucasfl)).
|
||||
* Add new setting `print_pretty_type_names` to print pretty deep nested types like Tuple/Maps/Arrays. [#55095](https://github.com/ClickHouse/ClickHouse/pull/55095) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Improve performance of sorting for decimal columns. Improve performance of insertion into MergeTree if ORDER BY contains Decimal column. Improve performance of sorting when data is already sorted or almost sorted. [#35961](https://github.com/ClickHouse/ClickHouse/pull/35961) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Improve performance for huge query analysis. Fixes [#51224](https://github.com/ClickHouse/ClickHouse/issues/51224). [#51469](https://github.com/ClickHouse/ClickHouse/pull/51469) ([frinkr](https://github.com/frinkr)).
|
||||
* 1. Add rewriter for new analyzer. [#52082](https://github.com/ClickHouse/ClickHouse/pull/52082) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* 1. Add rewriter for both old and new analyzer. 2. Add settings `optimize_uniq_to_count`. [#52645](https://github.com/ClickHouse/ClickHouse/pull/52645) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* Remove manual calls to `mmap/mremap/munmap` and delegate all this work to `jemalloc`. [#52792](https://github.com/ClickHouse/ClickHouse/pull/52792) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Now roaringBitmaps being optimized before serialization. [#52842](https://github.com/ClickHouse/ClickHouse/pull/52842) ([UnamedRus](https://github.com/UnamedRus)).
|
||||
* Optimize group by constant keys. Will optimize queries with group by `_file/_path` after https://github.com/ClickHouse/ClickHouse/pull/53529. [#53549](https://github.com/ClickHouse/ClickHouse/pull/53549) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Speed up reading from S3 by enabling prefetches by default. [#53709](https://github.com/ClickHouse/ClickHouse/pull/53709) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Do not implicitly read pk and version columns in lonely parts if unnecessary. [#53919](https://github.com/ClickHouse/ClickHouse/pull/53919) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Fixed high in CPU consumption when working with NATS. [#54399](https://github.com/ClickHouse/ClickHouse/pull/54399) ([Vasilev Pyotr](https://github.com/vahpetr)).
|
||||
* Since we use separate instructions for executing `toString()` with datetime argument, it is possible to improve performance a bit for non-datetime arguments and have some parts of the code cleaner. Follows up [#53680](https://github.com/ClickHouse/ClickHouse/issues/53680). [#54443](https://github.com/ClickHouse/ClickHouse/pull/54443) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Instead of serializing json elements into a `std::stringstream`, this PR try to put the serialization result into `ColumnString` direclty. [#54613](https://github.com/ClickHouse/ClickHouse/pull/54613) ([lgbo](https://github.com/lgbo-ustc)).
|
||||
* Enable ORDER BY optimization for reading data in corresponding order from a MergeTree table in case that the table is behind a view. [#54628](https://github.com/ClickHouse/ClickHouse/pull/54628) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Improve JSON SQL functions by reusing `GeneratorJSONPath`. Since there are several `make_shared` in `GenerateorJSONPath`'s constructor, it has bad performance. [#54735](https://github.com/ClickHouse/ClickHouse/pull/54735) ([lgbo](https://github.com/lgbo-ustc)).
|
||||
|
||||
#### Improvement
|
||||
* Keeper improvement: Add a `createIfNotExists` Keeper command. [#48855](https://github.com/ClickHouse/ClickHouse/pull/48855) ([Konstantin Bogdanov](https://github.com/thevar1able)).
|
||||
* Add IF EMPTY clause for DROP TABLE queries. [#48915](https://github.com/ClickHouse/ClickHouse/pull/48915) ([Pavel Novitskiy](https://github.com/pnovitskiy)).
|
||||
* The Keeper dynamically adjusts log levels. [#50372](https://github.com/ClickHouse/ClickHouse/pull/50372) ([helifu](https://github.com/helifu)).
|
||||
* Allow to replace long names of files of columns in `MergeTree` data parts to hashes of names. It helps to avoid `File name too long` error in some cases. [#50612](https://github.com/ClickHouse/ClickHouse/pull/50612) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Allow specifying the expiration date and, optionally, the time for user credentials with `VALID UNTIL datetime` clause. [#51261](https://github.com/ClickHouse/ClickHouse/pull/51261) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Add setting `ignore_access_denied_multidirectory_globs`. [#52839](https://github.com/ClickHouse/ClickHouse/pull/52839) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* Output valid JSON/XML on excetpion during HTTP query execution. Add setting `http_write_exception_in_output_format` to enable/disable this behaviour (enabled by default). [#52853](https://github.com/ClickHouse/ClickHouse/pull/52853) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* More precise Integer type inference, fix [#51236](https://github.com/ClickHouse/ClickHouse/issues/51236). [#53003](https://github.com/ClickHouse/ClickHouse/pull/53003) ([Chen768959](https://github.com/Chen768959)).
|
||||
* Keeper tries to batch flush requests for better performance. [#53049](https://github.com/ClickHouse/ClickHouse/pull/53049) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Introduced resolving of charsets in the string literals for MaterializedMySQL. [#53220](https://github.com/ClickHouse/ClickHouse/pull/53220) ([Val Doroshchuk](https://github.com/valbok)).
|
||||
* Fix a subtle issue with a rarely used `EmbeddedRocksDB` table engine in an extremely rare scenario: sometimes the `EmbeddedRocksDB` table engine does not close files correctly in NFS after running `DROP TABLE`. [#53502](https://github.com/ClickHouse/ClickHouse/pull/53502) ([Mingliang Pan](https://github.com/liangliangpan)).
|
||||
* SQL functions "toString(datetime)" and "formatDateTime()" now support non-constant timezone arguments. [#53680](https://github.com/ClickHouse/ClickHouse/pull/53680) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* `RESTORE TABLE ON CLUSTER` must create replicated tables with a matching UUID on hosts. Otherwise the macro `{uuid}` in ZooKeeper path can't work correctly after RESTORE. This PR implements that. [#53765](https://github.com/ClickHouse/ClickHouse/pull/53765) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Added restore setting `restore_broken_parts_as_detached`: if it's true the RESTORE process won't stop on broken parts while restoring, instead all the broken parts will be copied to the `detached` folder with the prefix `broken-from-backup'. If it's false the RESTORE process will stop on the first broken part (if any). The default value is false. [#53877](https://github.com/ClickHouse/ClickHouse/pull/53877) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* The creation of Annoy indexes can now be parallelized using setting `max_threads_for_annoy_index_creation`. [#54047](https://github.com/ClickHouse/ClickHouse/pull/54047) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* The MySQL interface gained a minimal implementation of prepared statements, just enough to allow a connection from Tableau Online to ClickHouse via the MySQL connector. [#54115](https://github.com/ClickHouse/ClickHouse/pull/54115) ([Serge Klochkov](https://github.com/slvrtrn)).
|
||||
* Replaced the library to handle (encode/decode) base64 values from Turbo-Base64 to aklomp-base64. Both are SIMD-accelerated on x86 and ARM but 1. the license of the latter (BSD-2) is more favorable for ClickHouse, Turbo64 switched in the meantime to GPL-3, 2. with more GitHub stars, aklomp-base64 seems more future-proof, 3. aklomp-base64 has a slightly nicer API (which is arguably subjective), and 4. aklomp-base64 does not require us to hack around bugs (like non-threadsafe initialization). Note: aklomp-base64 rejects unpadded base64 values whereas Turbo-Base64 decodes them on a best-effort basis. RFC-4648 leaves it open whether padding is mandatory or not, but depending on the context this may be a behavioral change to be aware of. [#54119](https://github.com/ClickHouse/ClickHouse/pull/54119) ([Mikhail Koviazin](https://github.com/mkmkme)).
|
||||
* Add elapsed_ns to HTTP headers X-ClickHouse-Progress and X-ClickHouse-Summary. [#54179](https://github.com/ClickHouse/ClickHouse/pull/54179) ([joelynch](https://github.com/joelynch)).
|
||||
* Implementation of `reconfig` (https://github.com/ClickHouse/ClickHouse/pull/49450), `sync`, and `exists` commands for keeper-client. [#54201](https://github.com/ClickHouse/ClickHouse/pull/54201) ([pufit](https://github.com/pufit)).
|
||||
* "clickhouse-local" and "clickhouse-client" now allow to specify the "--query" parameter multiple times, e.g. './clickhouse-client --query "SELECT 1" --query "SELECT 2"'. This syntax is slightly more intuitive than `./clickhouse-client --multiquery "SELECT 1;SELECT2", a bit easier to script (e.g. "queries.push_back('--query "$q"')") and more consistent with the behavior of existing parameter "--queries-file" (e.g. "./clickhouse client --queries-file queries1.sql --queries-file queries2.sql"). [#54249](https://github.com/ClickHouse/ClickHouse/pull/54249) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Add sub-second precision to `formatReadableTimeDelta`. [#54250](https://github.com/ClickHouse/ClickHouse/pull/54250) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* Fix wrong reallocation in HashedArrayDictionary:. [#54254](https://github.com/ClickHouse/ClickHouse/pull/54254) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Enable allow_remove_stale_moving_parts by default. [#54260](https://github.com/ClickHouse/ClickHouse/pull/54260) ([vdimir](https://github.com/vdimir)).
|
||||
* Fix using count from cache and improve progress bar for reading from archives. [#54271](https://github.com/ClickHouse/ClickHouse/pull/54271) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add support for S3 credentials using SSO. To define a profile to be used with SSO, set `AWS_PROFILE` environment variable. [#54347](https://github.com/ClickHouse/ClickHouse/pull/54347) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Support NULL as default for nested types Array/Tuple/Map for input formats. Closes [#51100](https://github.com/ClickHouse/ClickHouse/issues/51100). [#54351](https://github.com/ClickHouse/ClickHouse/pull/54351) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* This is actually a bug fix, but not sure I'll be able to add a test to support the case, so I have put it as an improvement. This issue was introduced in https://github.com/ClickHouse/ClickHouse/pull/45878, which is when CH started reading arrow in batches. [#54370](https://github.com/ClickHouse/ClickHouse/pull/54370) ([Arthur Passos](https://github.com/arthurpassos)).
|
||||
* Add STD alias to stddevPop function for MySQL compatibility. Closes [#54274](https://github.com/ClickHouse/ClickHouse/issues/54274). [#54382](https://github.com/ClickHouse/ClickHouse/pull/54382) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Add `addDate` function for compatibility with MySQL and `subDate` for consistency. Reference [#54275](https://github.com/ClickHouse/ClickHouse/issues/54275). [#54400](https://github.com/ClickHouse/ClickHouse/pull/54400) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Parse data in JSON format as JSONEachRow if failed to parse metadata. It will allow to read files with `.json` extension even if real format is JSONEachRow. Closes [#45740](https://github.com/ClickHouse/ClickHouse/issues/45740). [#54405](https://github.com/ClickHouse/ClickHouse/pull/54405) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Pass http retry timeout as milliseconds. [#54438](https://github.com/ClickHouse/ClickHouse/pull/54438) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Support SAMPLE BY for VIEW. [#54477](https://github.com/ClickHouse/ClickHouse/pull/54477) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Add modification_time into system.detached_parts. [#54506](https://github.com/ClickHouse/ClickHouse/pull/54506) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added a setting "splitby_max_substrings_includes_remaining_string" which controls if functions "splitBy*()" with argument "max_substring" > 0 include the remaining string (if any) in the result array (Python/Spark semantics) or not. The default behavior does not change. [#54518](https://github.com/ClickHouse/ClickHouse/pull/54518) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Now clickhouse-client process files in parallel in case of `INFILE 'glob_expression'`. Closes [#54218](https://github.com/ClickHouse/ClickHouse/issues/54218). [#54533](https://github.com/ClickHouse/ClickHouse/pull/54533) ([Max K.](https://github.com/mkaynov)).
|
||||
* Allow to use primary key for IN function where primary key column types are different from `IN` function right side column types. Example: `SELECT id FROM test_table WHERE id IN (SELECT '5')`. Closes [#48936](https://github.com/ClickHouse/ClickHouse/issues/48936). [#54544](https://github.com/ClickHouse/ClickHouse/pull/54544) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Better integer types inference for Int64/UInt64 fields. Continuation of https://github.com/ClickHouse/ClickHouse/pull/53003. Now it works also for nested types like Arrays of Arrays anf for functions like `map/tuple`. Issue: [#51236](https://github.com/ClickHouse/ClickHouse/issues/51236). [#54553](https://github.com/ClickHouse/ClickHouse/pull/54553) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* HashJoin tries to shrink internal buffers consuming half of maximal available memory (set by `max_bytes_in_join`). [#54584](https://github.com/ClickHouse/ClickHouse/pull/54584) ([vdimir](https://github.com/vdimir)).
|
||||
* Added array operations for multiplying, dividing and modulo on scalar. Works in each way, for example `5 * [5, 5]` and `[5, 5] * 5` - both cases are possible. [#54608](https://github.com/ClickHouse/ClickHouse/pull/54608) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Added function `timestamp` for compatibility with MySQL. Closes [#54275](https://github.com/ClickHouse/ClickHouse/issues/54275). [#54639](https://github.com/ClickHouse/ClickHouse/pull/54639) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Respect max_block_size for array join to avoid possible OOM. Close [#54290](https://github.com/ClickHouse/ClickHouse/issues/54290). [#54664](https://github.com/ClickHouse/ClickHouse/pull/54664) ([李扬](https://github.com/taiyang-li)).

|
||||
* Make it possible to use plural when using interval literals. `INTERVAL 2 HOURS` should be equivalent to `INTERVAL 2 HOUR`. [#54860](https://github.com/ClickHouse/ClickHouse/pull/54860) ([Jordi Villar](https://github.com/jrdi)).

|
||||
* LIKE, match, and other regular expressions matching functions now allow matching with patterns containing non-UTF-8 substrings by falling back to binary matching. Example: you can use `string LIKE '\xFE\xFF%'` to detect BOM. This closes [#54486](https://github.com/ClickHouse/ClickHouse/issues/54486).

## Data Type Detection

||||
When creating a tuple on the fly, ClickHouse automatically detects the type of each argument as the minimum of the types which can store the argument value. If the argument is [NULL](../../sql-reference/syntax.md#null-literal), the type of the tuple element is [Nullable](../../sql-reference/data-types/nullable.md).

When creating tuples on the fly, ClickHouse interferes the type of the tuples arguments as the smallest types which can hold the provided argument value.

||||
|
||||
Function `arrayRandomSample` returns a subset with `samples`-many random elements of an input array. If `samples` exceeds the size of the input array, the sample size is limited to the size of the array. In this case, all elements of the input array are returned, but the order is not guaranteed. The function can handle both flat arrays and nested arrays.
|
||||
|
||||
**Syntax**
|
||||
|
||||
```sql
|
||||
arrayRandomSample(arr, samples)
|
||||
```
|
||||
|
||||
**Arguments**
|
||||
|
||||
- `arr` — The input array from which to sample elements. This may be flat or nested arrays.
|
||||
- `samples` — An unsigned integer specifying the number of elements to include in the random sample.
|
||||
|
||||
**Returned Value**
|
||||
|
||||
- An array containing a random sample of elements from the input array.
