### <a id="2312"></a> ClickHouse release 23.12, 2023-12-28
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Fix check for non-deterministic functions in TTL expressions. Previously, you could create a TTL expression with non-deterministic functions in some cases, which could lead to undefined behavior later. This fixes [#37250](https://github.com/ClickHouse/ClickHouse/issues/37250). Disallow TTL expressions that don't depend on any columns of a table by default. It can be allowed back by `SET allow_suspicious_ttl_expressions = 1` or `SET compatibility = '23.11'`. Closes [#37286](https://github.com/ClickHouse/ClickHouse/issues/37286). [#51858](https://github.com/ClickHouse/ClickHouse/pull/51858) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* The MergeTree setting `clean_deleted_rows` is deprecated, it has no effect anymore. The `CLEANUP` keyword for the `OPTIMIZE` is not allowed by default (it can be unlocked with the `allow_experimental_replacing_merge_with_cleanup` setting). [#58267](https://github.com/ClickHouse/ClickHouse/pull/58267) ([Alexander Tokmakov](https://github.com/tavplubix)). This fixes [#57930](https://github.com/ClickHouse/ClickHouse/issues/57930). This closes [#54988](https://github.com/ClickHouse/ClickHouse/issues/54988). This closes [#54570](https://github.com/ClickHouse/ClickHouse/issues/54570). This closes [#50346](https://github.com/ClickHouse/ClickHouse/issues/50346). This closes [#47579](https://github.com/ClickHouse/ClickHouse/issues/47579). The feature has to be removed because it is not good. We have to remove it as quickly as possible, because there is no other option. [#57932](https://github.com/ClickHouse/ClickHouse/pull/57932) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
|
||||
#### New Feature
|
||||
* Implement Refreshable Materialized Views, requested in [#33919](https://github.com/ClickHouse/ClickHouse/issues/57995). [#56946](https://github.com/ClickHouse/ClickHouse/pull/56946) ([Michael Kolupaev](https://github.com/al13n321), [Michael Guzov](https://github.com/koloshmet)).
|
||||
* Introduce `PASTE JOIN`, which allows users to join tables without `ON` clause simply by row numbers. Example: `SELECT * FROM (SELECT number AS a FROM numbers(2)) AS t1 PASTE JOIN (SELECT number AS a FROM numbers(2) ORDER BY a DESC) AS t2`. [#57995](https://github.com/ClickHouse/ClickHouse/pull/57995) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* The `ORDER BY` clause now supports specifying `ALL`, meaning that ClickHouse sorts by all columns in the `SELECT` clause. Example: `SELECT col1, col2 FROM tab WHERE [...] ORDER BY ALL`. [#57875](https://github.com/ClickHouse/ClickHouse/pull/57875) ([zhongyuankai](https://github.com/zhongyuankai)).
|
||||
* Added a new mutation command `ALTER TABLE <table> APPLY DELETED MASK`, which allows to enforce applying of mask written by lightweight delete and to remove rows marked as deleted from disk. [#57433](https://github.com/ClickHouse/ClickHouse/pull/57433) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* A handler `/binary` opens a visual viewer of symbols inside the ClickHouse binary. [#58211](https://github.com/ClickHouse/ClickHouse/pull/58211) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Added a new SQL function `sqid` to generate Sqids (https://sqids.org/), example: `SELECT sqid(125, 126)`. [#57512](https://github.com/ClickHouse/ClickHouse/pull/57512) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Add a new function `seriesPeriodDetectFFT` to detect series period using FFT. [#57574](https://github.com/ClickHouse/ClickHouse/pull/57574) ([Bhavna Jindal](https://github.com/bhavnajindal)).
|
||||
* Add an HTTP endpoint for checking if Keeper is ready to accept traffic. [#55876](https://github.com/ClickHouse/ClickHouse/pull/55876) ([Konstantin Bogdanov](https://github.com/thevar1able)).
|
||||
* Add 'union' mode for schema inference. In this mode the resulting table schema is the union of all files schemas (so schema is inferred from each file). The mode of schema inference is controlled by a setting `schema_inference_mode` with two possible values - `default` and `union`. Closes [#55428](https://github.com/ClickHouse/ClickHouse/issues/55428). [#55892](https://github.com/ClickHouse/ClickHouse/pull/55892) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add new setting `input_format_csv_try_infer_numbers_from_strings` that allows to infer numbers from strings in CSV format. Closes [#56455](https://github.com/ClickHouse/ClickHouse/issues/56455). [#56859](https://github.com/ClickHouse/ClickHouse/pull/56859) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* When the number of databases or tables exceeds a configurable threshold, show a warning to the user. [#57375](https://github.com/ClickHouse/ClickHouse/pull/57375) ([凌涛](https://github.com/lingtaolf)).
|
||||
* Dictionary with `HASHED_ARRAY` (and `COMPLEX_KEY_HASHED_ARRAY`) layout supports `SHARDS` similarly to `HASHED`. [#57544](https://github.com/ClickHouse/ClickHouse/pull/57544) ([vdimir](https://github.com/vdimir)).
|
||||
* Add asynchronous metrics for total primary key bytes and total allocated primary key bytes in memory. [#57551](https://github.com/ClickHouse/ClickHouse/pull/57551) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Add `SHA512_256` function. [#57645](https://github.com/ClickHouse/ClickHouse/pull/57645) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Add `FORMAT_BYTES` as an alias for `formatReadableSize`. [#57592](https://github.com/ClickHouse/ClickHouse/pull/57592) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Allow passing optional session token to the `s3` table function. [#57850](https://github.com/ClickHouse/ClickHouse/pull/57850) ([Shani Elharrar](https://github.com/shanielh)).
|
||||
* Introduce a new setting `http_make_head_request`. If it is turned off, the URL table engine will not do a HEAD request to determine the file size. This is needed to support inefficient, misconfigured, or not capable HTTP servers. [#54602](https://github.com/ClickHouse/ClickHouse/pull/54602) ([Fionera](https://github.com/fionera)).
|
||||
* It is now possible to refer to ALIAS column in index (non-primary-key) definitions (issue [#55650](https://github.com/ClickHouse/ClickHouse/issues/55650)). Example: `CREATE TABLE tab(col UInt32, col_alias ALIAS col + 1, INDEX idx (col_alias) TYPE minmax) ENGINE = MergeTree ORDER BY col;`. [#57546](https://github.com/ClickHouse/ClickHouse/pull/57546) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Added a new setting `readonly` which can be used to specify an S3 disk is read only. It can be useful to create a table on a disk of `s3_plain` type, while having read only access to the underlying S3 bucket. [#57977](https://github.com/ClickHouse/ClickHouse/pull/57977) ([Pengyuan Bian](https://github.com/bianpengyuan)).
|
||||
* The primary key analysis in MergeTree tables will now be applied to predicates that include the virtual column `_part_offset` (optionally with `_part`). This feature can serve as a special kind of a secondary index. [#58224](https://github.com/ClickHouse/ClickHouse/pull/58224) ([Amos Bird](https://github.com/amosbird)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Extract non-intersecting parts ranges from MergeTree table during FINAL processing. That way we can avoid additional FINAL logic for this non-intersecting parts ranges. In case when amount of duplicate values with same primary key is low, performance will be almost the same as without FINAL. Improve reading performance for MergeTree FINAL when `do_not_merge_across_partitions_select_final` setting is set. [#58120](https://github.com/ClickHouse/ClickHouse/pull/58120) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Made copy between s3 disks using a s3-server-side copy instead of copying through the buffer. Improves `BACKUP/RESTORE` operations and `clickhouse-disks copy` command. [#56744](https://github.com/ClickHouse/ClickHouse/pull/56744) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
|
||||
* Hash JOIN respects setting `max_joined_block_size_rows` and do not produce large blocks for `ALL JOIN`. [#56996](https://github.com/ClickHouse/ClickHouse/pull/56996) ([vdimir](https://github.com/vdimir)).
|
||||
* Release memory for aggregation earlier. This may avoid unnecessary external aggregation. [#57691](https://github.com/ClickHouse/ClickHouse/pull/57691) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Improve performance of string serialization. [#57717](https://github.com/ClickHouse/ClickHouse/pull/57717) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Support trivial count optimization for `Merge`-engine tables. [#57867](https://github.com/ClickHouse/ClickHouse/pull/57867) ([skyoct](https://github.com/skyoct)).
|
||||
* Optimized aggregation in some cases. [#57872](https://github.com/ClickHouse/ClickHouse/pull/57872) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* The `hasAny` function can now take advantage of the full-text skipping indices. [#57878](https://github.com/ClickHouse/ClickHouse/pull/57878) ([Jpnock](https://github.com/Jpnock)).
|
||||
* Function `if(cond, then, else)` (and its alias `cond ? then : else`) were optimized to use branch-free evaluation. [#57885](https://github.com/ClickHouse/ClickHouse/pull/57885) ([zhanglistar](https://github.com/zhanglistar)).
|
||||
* MergeTree automatically derive `do_not_merge_across_partitions_select_final` setting if partition key expression contains only columns from primary key expression. [#58218](https://github.com/ClickHouse/ClickHouse/pull/58218) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Speedup `MIN` and `MAX` for native types. [#58231](https://github.com/ClickHouse/ClickHouse/pull/58231) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Implement `SLRU` cache policy for filesystem cache. [#57076](https://github.com/ClickHouse/ClickHouse/pull/57076) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* The limit for the number of connections per endpoint for background fetches was raised from `15` to the value of `background_fetches_pool_size` setting. - MergeTree-level setting `replicated_max_parallel_fetches_for_host` became obsolete - MergeTree-level settings `replicated_fetches_http_connection_timeout`, `replicated_fetches_http_send_timeout` and `replicated_fetches_http_receive_timeout` are moved to the Server-level. - Setting `keep_alive_timeout` is added to the list of Server-level settings. [#57523](https://github.com/ClickHouse/ClickHouse/pull/57523) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Make querying `system.filesystem_cache` not memory intensive. [#57687](https://github.com/ClickHouse/ClickHouse/pull/57687) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Reduce memory usage on strings deserialization. [#57787](https://github.com/ClickHouse/ClickHouse/pull/57787) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* More efficient constructor for Enum - it makes sense when Enum has a boatload of values. [#57887](https://github.com/ClickHouse/ClickHouse/pull/57887) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* An improvement for reading from the filesystem cache: always use `pread` method. [#57970](https://github.com/ClickHouse/ClickHouse/pull/57970) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Add optimization for AND notEquals chain in logical expression optimizer. This optimization is only available with the experimental Analyzer enabled. [#58214](https://github.com/ClickHouse/ClickHouse/pull/58214) ([Kevin Mingtarja](https://github.com/kevinmingtarja)).
|
||||
|
||||
#### Improvement
|
||||
* Support for soft memory limit in Keeper. It will refuse requests if the memory usage is close to the maximum. [#57271](https://github.com/ClickHouse/ClickHouse/pull/57271) ([Han Fei](https://github.com/hanfei1991)). [#57699](https://github.com/ClickHouse/ClickHouse/pull/57699) ([Han Fei](https://github.com/hanfei1991)).
|
||||
* Make inserts into distributed tables handle updated cluster configuration properly. When the list of cluster nodes is dynamically updated, the Directory Monitor of the distribution table will update it. [#42826](https://github.com/ClickHouse/ClickHouse/pull/42826) ([zhongyuankai](https://github.com/zhongyuankai)).
|
||||
* Do not allow creating a replicated table with inconsistent merge parameters. [#56833](https://github.com/ClickHouse/ClickHouse/pull/56833) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Show uncompressed size in `system.tables`. [#56618](https://github.com/ClickHouse/ClickHouse/issues/56618). [#57186](https://github.com/ClickHouse/ClickHouse/pull/57186) ([Chen Lixiang](https://github.com/chenlx0)).
|
||||
* Add `skip_unavailable_shards` as a setting for `Distributed` tables that is similar to the corresponding query-level setting. Closes [#43666](https://github.com/ClickHouse/ClickHouse/issues/43666). [#57218](https://github.com/ClickHouse/ClickHouse/pull/57218) ([Gagan Goel](https://github.com/tntnatbry)).
|
||||
* The function `substring` (aliases: `substr`, `mid`) can now be used with `Enum` types. Previously, the first function argument had to be a value of type `String` or `FixedString`. This improves compatibility with 3rd party tools such as Tableau via MySQL interface. [#57277](https://github.com/ClickHouse/ClickHouse/pull/57277) ([Serge Klochkov](https://github.com/slvrtrn)).
|
||||
* Function `format` now supports arbitrary argument types (instead of only `String` and `FixedString` arguments). This is important to calculate `SELECT format('The {0} to all questions is {1}', 'answer', 42)`. [#57549](https://github.com/ClickHouse/ClickHouse/pull/57549) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Allows to use the `date_trunc` function with a case-insensitive first argument. Both cases are now supported: `SELECT date_trunc('day', now())` and `SELECT date_trunc('DAY', now())`. [#57624](https://github.com/ClickHouse/ClickHouse/pull/57624) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Better hints when a table doesn't exist. [#57342](https://github.com/ClickHouse/ClickHouse/pull/57342) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Allow to overwrite `max_partition_size_to_drop` and `max_table_size_to_drop` server settings in query time. [#57452](https://github.com/ClickHouse/ClickHouse/pull/57452) ([Jordi Villar](https://github.com/jrdi)).
|
||||
* Slightly better inference of unnamed tupes in JSON formats. [#57751](https://github.com/ClickHouse/ClickHouse/pull/57751) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add support for read-only flag when connecting to Keeper (fixes [#53749](https://github.com/ClickHouse/ClickHouse/issues/53749)). [#57479](https://github.com/ClickHouse/ClickHouse/pull/57479) ([Mikhail Koviazin](https://github.com/mkmkme)).
|
||||
* Fix possible distributed sends stuck due to "No such file or directory" (during recovering a batch from disk). Fix possible issues with `error_count` from `system.distribution_queue` (in case of `distributed_directory_monitor_max_sleep_time_ms` >5min). Introduce profile event to track async INSERT failures - `DistributedAsyncInsertionFailures`. [#57480](https://github.com/ClickHouse/ClickHouse/pull/57480) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Support PostgreSQL generated columns and default column values in `MaterializedPostgreSQL` (experimental feature). Closes [#40449](https://github.com/ClickHouse/ClickHouse/issues/40449). [#57568](https://github.com/ClickHouse/ClickHouse/pull/57568) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Allow to apply some filesystem cache config settings changes without server restart. [#57578](https://github.com/ClickHouse/ClickHouse/pull/57578) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Properly handling PostgreSQL table structure with empty array. [#57618](https://github.com/ClickHouse/ClickHouse/pull/57618) ([Mike Kot](https://github.com/myrrc)).
|
||||
* Expose the total number of errors occurred since last server restart as a `ClickHouseErrorMetric_ALL` metric. [#57627](https://github.com/ClickHouse/ClickHouse/pull/57627) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Allow nodes in the configuration file with `from_env`/`from_zk` reference and non empty element with replace=1. [#57628](https://github.com/ClickHouse/ClickHouse/pull/57628) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* A table function `fuzzJSON` which allows generating a lot of malformed JSON for fuzzing. [#57646](https://github.com/ClickHouse/ClickHouse/pull/57646) ([Julia Kartseva](https://github.com/jkartseva)).
|
||||
* Allow IPv6 to UInt128 conversion and binary arithmetic. [#57707](https://github.com/ClickHouse/ClickHouse/pull/57707) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Add a setting for `async inserts deduplication cache` - how long we wait for cache update. Deprecate setting `async_block_ids_cache_min_update_interval_ms`. Now cache is updated only in case of conflicts. [#57743](https://github.com/ClickHouse/ClickHouse/pull/57743) ([alesapin](https://github.com/alesapin)).
|
||||
* `sleep()` function now can be cancelled with `KILL QUERY`. [#57746](https://github.com/ClickHouse/ClickHouse/pull/57746) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Forbid `CREATE TABLE ... AS SELECT` queries for `Replicated` table engines in the experimental `Replicated` database because they are not supported. Reference [#35408](https://github.com/ClickHouse/ClickHouse/issues/35408). [#57796](https://github.com/ClickHouse/ClickHouse/pull/57796) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Fix and improve transforming queries for external databases, to recursively obtain all compatible predicates. [#57888](https://github.com/ClickHouse/ClickHouse/pull/57888) ([flynn](https://github.com/ucasfl)).
|
||||
* Support dynamic reloading of the filesystem cache size. Closes [#57866](https://github.com/ClickHouse/ClickHouse/issues/57866). [#57897](https://github.com/ClickHouse/ClickHouse/pull/57897) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Correctly support `system.stack_trace` for threads with blocked SIGRTMIN (these threads can exist in low-quality external libraries such as Apache rdkafka). [#57907](https://github.com/ClickHouse/ClickHouse/pull/57907) ([Azat Khuzhin](https://github.com/azat)). Aand also send signal to the threads only if it is not blocked to avoid waiting `storage_system_stack_trace_pipe_read_timeout_ms` when it does not make any sense. [#58136](https://github.com/ClickHouse/ClickHouse/pull/58136) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Tolerate keeper failures in the quorum inserts' check. [#57986](https://github.com/ClickHouse/ClickHouse/pull/57986) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Add max/peak RSS (`MemoryResidentMax`) into system.asynchronous_metrics. [#58095](https://github.com/ClickHouse/ClickHouse/pull/58095) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* This PR allows users to use s3-style links (`https://` and `s3://`) without mentioning region if it's not default. Also find the correct region if the user mentioned the wrong one. [#58148](https://github.com/ClickHouse/ClickHouse/pull/58148) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* `clickhouse-format --obfuscate` will know about Settings, MergeTreeSettings, and time zones and keep their names unchanged. [#58179](https://github.com/ClickHouse/ClickHouse/pull/58179) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Added explicit `finalize()` function in `ZipArchiveWriter`. Simplify too complicated code in `ZipArchiveWriter`. This fixes [#58074](https://github.com/ClickHouse/ClickHouse/issues/58074). [#58202](https://github.com/ClickHouse/ClickHouse/pull/58202) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Make caches with the same path use the same cache objects. This behaviour existed before, but was broken in 23.4. If such caches with the same path have different set of cache settings, an exception will be thrown, that this is not allowed. [#58264](https://github.com/ClickHouse/ClickHouse/pull/58264) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Parallel replicas (experimental feature): friendly settings [#57542](https://github.com/ClickHouse/ClickHouse/pull/57542) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
* Parallel replicas (experimental feature): announcement response handling improvement [#57749](https://github.com/ClickHouse/ClickHouse/pull/57749) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
* Parallel replicas (experimental feature): give more respect to `min_number_of_marks` in `ParallelReplicasReadingCoordinator` [#57763](https://github.com/ClickHouse/ClickHouse/pull/57763) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Parallel replicas (experimental feature): disable parallel replicas with IN (subquery) [#58133](https://github.com/ClickHouse/ClickHouse/pull/58133) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
* Parallel replicas (experimental feature): add profile event 'ParallelReplicasUsedCount' [#58173](https://github.com/ClickHouse/ClickHouse/pull/58173) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
* Non POST requests such as HEAD will be readonly similar to GET. [#58060](https://github.com/ClickHouse/ClickHouse/pull/58060) ([San](https://github.com/santrancisco)).
|
||||
* Add `bytes_uncompressed` column to `system.part_log` [#58167](https://github.com/ClickHouse/ClickHouse/pull/58167) ([Jordi Villar](https://github.com/jrdi)).
|
||||
* Add base backup name to `system.backups` and `system.backup_log` tables [#58178](https://github.com/ClickHouse/ClickHouse/pull/58178) ([Pradeep Chhetri](https://github.com/chhetripradeep)).
|
||||
* Add support for specifying query parameters in the command line in clickhouse-local [#58210](https://github.com/ClickHouse/ClickHouse/pull/58210) ([Pradeep Chhetri](https://github.com/chhetripradeep)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|

# 2023 Changelog
|

|
||||
### ClickHouse release v23.12.1.1368-stable (a2faa65b080) FIXME as compared to v23.11.1.2711-stable (05bc8ef1e02)
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Fix check for non-deterministic functions in TTL expressions. Previously, you could create a TTL expression with non-deterministic functions in some cases, which could lead to undefined behavior later. This fixes [#37250](https://github.com/ClickHouse/ClickHouse/issues/37250). Disallow TTL expressions that don't depend on any columns of a table by default. It can be allowed back by `SET allow_suspicious_ttl_expressions = 1` or `SET compatibility = '23.11'`. Closes [#37286](https://github.com/ClickHouse/ClickHouse/issues/37286). [#51858](https://github.com/ClickHouse/ClickHouse/pull/51858) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Remove function `arrayFold` because it has a bug. This closes [#57816](https://github.com/ClickHouse/ClickHouse/issues/57816). This closes [#57458](https://github.com/ClickHouse/ClickHouse/issues/57458). [#57836](https://github.com/ClickHouse/ClickHouse/pull/57836) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Remove the feature of `is_deleted` row in ReplacingMergeTree and the `CLEANUP` modifier for the OPTIMIZE query. This fixes [#57930](https://github.com/ClickHouse/ClickHouse/issues/57930). This closes [#54988](https://github.com/ClickHouse/ClickHouse/issues/54988). This closes [#54570](https://github.com/ClickHouse/ClickHouse/issues/54570). This closes [#50346](https://github.com/ClickHouse/ClickHouse/issues/50346). This closes [#47579](https://github.com/ClickHouse/ClickHouse/issues/47579). The feature has to be removed because it is not good. We have to remove it as quickly as possible, because there is no other option. [#57932](https://github.com/ClickHouse/ClickHouse/pull/57932) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* The MergeTree setting `clean_deleted_rows` is deprecated, it has no effect anymore. The `CLEANUP` keyword for `OPTIMIZE` is not allowed by default (unless `allow_experimental_replacing_merge_with_cleanup` is enabled). [#58267](https://github.com/ClickHouse/ClickHouse/pull/58267) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
|
||||
#### New Feature
|
||||
* Allow disabling of HEAD request before GET request. [#54602](https://github.com/ClickHouse/ClickHouse/pull/54602) ([Fionera](https://github.com/fionera)).
|
||||
* Add a HTTP endpoint for checking if Keeper is ready to accept traffic. [#55876](https://github.com/ClickHouse/ClickHouse/pull/55876) ([Konstantin Bogdanov](https://github.com/thevar1able)).
|
||||
* Add 'union' mode for schema inference. In this mode the resulting table schema is the union of all files schemas (so schema is inferred from each file). The mode of schema inference is controlled by a setting `schema_inference_mode` with 2 possible values - `default` and `union`. Closes [#55428](https://github.com/ClickHouse/ClickHouse/issues/55428). [#55892](https://github.com/ClickHouse/ClickHouse/pull/55892) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add new setting `input_format_csv_try_infer_numbers_from_strings` that allows to infer numbers from strings in CSV format. Closes [#56455](https://github.com/ClickHouse/ClickHouse/issues/56455). [#56859](https://github.com/ClickHouse/ClickHouse/pull/56859) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Refreshable materialized views. [#56946](https://github.com/ClickHouse/ClickHouse/pull/56946) ([Michael Kolupaev](https://github.com/al13n321)).
|
||||
* Add more warnings on the number of databases, tables. [#57375](https://github.com/ClickHouse/ClickHouse/pull/57375) ([凌涛](https://github.com/lingtaolf)).
|
||||
* Added a new mutation command `ALTER TABLE <table> APPLY DELETED MASK`, which allows to enforce applying of mask written by lightweight delete and to remove rows marked as deleted from disk. [#57433](https://github.com/ClickHouse/ClickHouse/pull/57433) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Added a new SQL function `sqid` to generate Sqids (https://sqids.org/), example: `SELECT sqid(125, 126)`. [#57512](https://github.com/ClickHouse/ClickHouse/pull/57512) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Dictionary with `HASHED_ARRAY` (and `COMPLEX_KEY_HASHED_ARRAY`) layout supports `SHARDS` similarly to `HASHED`. [#57544](https://github.com/ClickHouse/ClickHouse/pull/57544) ([vdimir](https://github.com/vdimir)).
|
||||
* Add asynchronous metrics for total primary key bytes and total allocated primary key bytes in memory. [#57551](https://github.com/ClickHouse/ClickHouse/pull/57551) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Table system.dropped_tables_parts contains parts of system.dropped_tables tables (dropped but not yet removed tables). [#57555](https://github.com/ClickHouse/ClickHouse/pull/57555) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Add `FORMAT_BYTES` as an alias for `formatReadableSize`. [#57592](https://github.com/ClickHouse/ClickHouse/pull/57592) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Add SHA512_256 function. [#57645](https://github.com/ClickHouse/ClickHouse/pull/57645) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Allow passing optional SESSION_TOKEN to `s3` table function. [#57850](https://github.com/ClickHouse/ClickHouse/pull/57850) ([Shani Elharrar](https://github.com/shanielh)).
|
||||
* Clause `ORDER BY` now supports specifying `ALL`, meaning that ClickHouse sorts by all columns in the `SELECT` clause. Example: `SELECT col1, col2 FROM tab WHERE [...] ORDER BY ALL`. [#57875](https://github.com/ClickHouse/ClickHouse/pull/57875) ([zhongyuankai](https://github.com/zhongyuankai)).
|
||||
* Added functions for punycode encoding/decoding: `punycodeEncode()` and `punycodeDecode()`. [#57969](https://github.com/ClickHouse/ClickHouse/pull/57969) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* This PR reproduces the implementation of `PASTE JOIN`, which allows users to join tables without `ON` clause. Example: ``` SQL SELECT * FROM ( SELECT number AS a FROM numbers(2) ) AS t1 PASTE JOIN ( SELECT number AS a FROM numbers(2) ORDER BY a DESC ) AS t2. [#57995](https://github.com/ClickHouse/ClickHouse/pull/57995) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* A handler `/binary` opens a visual viewer of symbols inside the ClickHouse binary. [#58211](https://github.com/ClickHouse/ClickHouse/pull/58211) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Made copy between s3 disks using a s3-server-side copy instead of copying through the buffer. Improves `BACKUP/RESTORE` operations and `clickhouse-disks copy` command. [#56744](https://github.com/ClickHouse/ClickHouse/pull/56744) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
|
||||
* HashJoin respects setting `max_joined_block_size_rows` and do not produce large blocks for `ALL JOIN`. [#56996](https://github.com/ClickHouse/ClickHouse/pull/56996) ([vdimir](https://github.com/vdimir)).
|
||||
* Release memory for aggregation earlier. This may avoid unnecessary external aggregation. [#57691](https://github.com/ClickHouse/ClickHouse/pull/57691) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Improve performance of string serialization. [#57717](https://github.com/ClickHouse/ClickHouse/pull/57717) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Support trivial count optimization for `Merge`-engine tables. [#57867](https://github.com/ClickHouse/ClickHouse/pull/57867) ([skyoct](https://github.com/skyoct)).
|
||||
* Optimized aggregation in some cases. [#57872](https://github.com/ClickHouse/ClickHouse/pull/57872) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* The `hasAny()` function can now take advantage of the full-text skipping indices. [#57878](https://github.com/ClickHouse/ClickHouse/pull/57878) ([Jpnock](https://github.com/Jpnock)).
|
||||
* Function `if(cond, then, else)` (and its alias `cond ? : then : else`) were optimized to use branch-free evaluation. [#57885](https://github.com/ClickHouse/ClickHouse/pull/57885) ([zhanglistar](https://github.com/zhanglistar)).
|
||||
* Extract non intersecting parts ranges from MergeTree table during FINAL processing. That way we can avoid additional FINAL logic for this non intersecting parts ranges. In case when amount of duplicate values with same primary key is low, performance will be almost the same as without FINAL. Improve reading performance for MergeTree FINAL when `do_not_merge_across_partitions_select_final` setting is set. [#58120](https://github.com/ClickHouse/ClickHouse/pull/58120) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* MergeTree automatically derive `do_not_merge_across_partitions_select_final` setting if partition key expression contains only columns from primary key expression. [#58218](https://github.com/ClickHouse/ClickHouse/pull/58218) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Speedup MIN and MAX for native types. [#58231](https://github.com/ClickHouse/ClickHouse/pull/58231) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
|
||||
#### Improvement
|
||||
* Make inserts into distributed tables handle updated cluster configuration properly. When the list of cluster nodes is dynamically updated, the Directory Monitor of the distribution table cannot sense the new node, and the Directory Monitor must be re-noded to sense it. [#42826](https://github.com/ClickHouse/ClickHouse/pull/42826) ([zhongyuankai](https://github.com/zhongyuankai)).
|
||||
* Replace --no-system-tables with loading virtual tables of system database lazily. [#55271](https://github.com/ClickHouse/ClickHouse/pull/55271) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Clickhouse-test print case sn, current time and case name in one test case. [#55710](https://github.com/ClickHouse/ClickHouse/pull/55710) ([guoxiaolong](https://github.com/guoxiaolongzte)).
|
||||
* Do not allow creating replicated table with inconsistent merge params. [#56833](https://github.com/ClickHouse/ClickHouse/pull/56833) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Implement SLRU cache policy for filesystem cache. [#57076](https://github.com/ClickHouse/ClickHouse/pull/57076) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Show uncompressed size in `system.tables`, obtained from data parts' checksums [#56618](https://github.com/ClickHouse/ClickHouse/issues/56618). [#57186](https://github.com/ClickHouse/ClickHouse/pull/57186) ([Chen Lixiang](https://github.com/chenlx0)).
|
||||
* Add `skip_unavailable_shards` as a setting for `Distributed` tables that is similar to the corresponding query-level setting. Closes [#43666](https://github.com/ClickHouse/ClickHouse/issues/43666). [#57218](https://github.com/ClickHouse/ClickHouse/pull/57218) ([Gagan Goel](https://github.com/tntnatbry)).
|
||||
* Function `substring()` (aliases: `substr`, `mid`) can now be used with `Enum` types. Previously, the first function argument had to be a value of type `String` or `FixedString`. This improves compatibility with 3rd party tools such as Tableau via MySQL interface. [#57277](https://github.com/ClickHouse/ClickHouse/pull/57277) ([Serge Klochkov](https://github.com/slvrtrn)).
|
||||
* Better hints when a table doesn't exist. [#57342](https://github.com/ClickHouse/ClickHouse/pull/57342) ([Bharat Nallan](https://github.com/bharatnc)).
|
||||
* Allow to overwrite `max_partition_size_to_drop` and `max_table_size_to_drop` server settings in query time. [#57452](https://github.com/ClickHouse/ClickHouse/pull/57452) ([Jordi Villar](https://github.com/jrdi)).
|
||||
* Add support for read-only flag when connecting to the ZooKeeper server (fixes [#53749](https://github.com/ClickHouse/ClickHouse/issues/53749)). [#57479](https://github.com/ClickHouse/ClickHouse/pull/57479) ([Mikhail Koviazin](https://github.com/mkmkme)).
|
||||
* Fix possible distributed sends stuck due to "No such file or directory" (during recovering batch from disk). Fix possible issues with `error_count` from `system.distribution_queue` (in case of `distributed_directory_monitor_max_sleep_time_ms` >5min). Introduce profile event to track async INSERT failures - `DistributedAsyncInsertionFailures`. [#57480](https://github.com/ClickHouse/ClickHouse/pull/57480) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* The limit for the number of connections per endpoint for background fetches was raised from `15` to the value of `background_fetches_pool_size` setting. - MergeTree-level setting `replicated_max_parallel_fetches_for_host` became obsolete - MergeTree-level settings `replicated_fetches_http_connection_timeout`, `replicated_fetches_http_send_timeout` and `replicated_fetches_http_receive_timeout` are moved to the Server-level. - Setting `keep_alive_timeout` is added to the list of Server-level settings. [#57523](https://github.com/ClickHouse/ClickHouse/pull/57523) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* It is now possible to refer to ALIAS column in index (non-primary-key) definitions (issue [#55650](https://github.com/ClickHouse/ClickHouse/issues/55650)). Example: `CREATE TABLE tab(col UInt32, col_alias ALIAS col + 1, INDEX idx (col_alias) TYPE minmax) ENGINE = MergeTree ORDER BY col;`. [#57546](https://github.com/ClickHouse/ClickHouse/pull/57546) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Function `format()` now supports arbitrary argument types (instead of only `String` and `FixedString` arguments). This is important to calculate `SELECT format('The {0} to all questions is {1}', 'answer', 42)`. [#57549](https://github.com/ClickHouse/ClickHouse/pull/57549) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Support PostgreSQL generated columns and default column values in `MaterializedPostgreSQL`. Closes [#40449](https://github.com/ClickHouse/ClickHouse/issues/40449). [#57568](https://github.com/ClickHouse/ClickHouse/pull/57568) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Allow to apply some filesystem cache config settings changes without server restart. [#57578](https://github.com/ClickHouse/ClickHouse/pull/57578) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Handle sigabrt case when getting PostgreSQl table structure with empty array. [#57618](https://github.com/ClickHouse/ClickHouse/pull/57618) ([Mike Kot (Михаил Кот)](https://github.com/myrrc)).
|
||||
* Allows to use the `date_trunc()` function with the first argument not depending on the case of it. Both cases are now supported: `SELECT date_trunc('day', now())` and `SELECT date_trunc('DAY', now())`. [#57624](https://github.com/ClickHouse/ClickHouse/pull/57624) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* Expose the total number of errors occurred since last server as a `ClickHouseErrorMetric_ALL` metric. [#57627](https://github.com/ClickHouse/ClickHouse/pull/57627) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Allow nodes in config with from_env/from_zk and non empty element with replace=1. [#57628](https://github.com/ClickHouse/ClickHouse/pull/57628) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Generate malformed output that cannot be parsed as JSON. [#57646](https://github.com/ClickHouse/ClickHouse/pull/57646) ([Julia Kartseva](https://github.com/jkartseva)).
|
||||
* Consider lightweight deleted rows when selecting parts to merge if enabled. [#57648](https://github.com/ClickHouse/ClickHouse/pull/57648) ([Zhuo Qiu](https://github.com/jewelzqiu)).
|
||||
* Make querying system.filesystem_cache not memory intensive. [#57687](https://github.com/ClickHouse/ClickHouse/pull/57687) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Allow IPv6 to UInt128 conversion and binary arithmetic. [#57707](https://github.com/ClickHouse/ClickHouse/pull/57707) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Support negative positional arguments. Closes [#57736](https://github.com/ClickHouse/ClickHouse/issues/57736). [#57741](https://github.com/ClickHouse/ClickHouse/pull/57741) ([flynn](https://github.com/ucasfl)).
|
||||
* Add a setting for `async inserts deduplication cache` -- how long we wait for cache update. Deprecate setting `async_block_ids_cache_min_update_interval_ms`. Now cache is updated only in case of conflicts. [#57743](https://github.com/ClickHouse/ClickHouse/pull/57743) ([alesapin](https://github.com/alesapin)).
|
||||
* `sleep()` function now can be cancelled with `KILL QUERY`. [#57746](https://github.com/ClickHouse/ClickHouse/pull/57746) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Slightly better inference of unnamed tupes in JSON formats. [#57751](https://github.com/ClickHouse/ClickHouse/pull/57751) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Refactor UserDefinedSQL* classes to make it possible to add SQL UDF storages which are different from ZooKeeper and Disk. [#57752](https://github.com/ClickHouse/ClickHouse/pull/57752) ([Natasha Chizhonkova](https://github.com/chizhonkova)).
|
||||
* Forbid `CREATE TABLE ... AS SELECT` queries for Replicated table engines in Replicated database because they are broken. Reference [#35408](https://github.com/ClickHouse/ClickHouse/issues/35408). [#57796](https://github.com/ClickHouse/ClickHouse/pull/57796) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Fix and improve transform query for external database, we should recursively obtain all compatible predicates. [#57888](https://github.com/ClickHouse/ClickHouse/pull/57888) ([flynn](https://github.com/ucasfl)).
|
||||
* Support dynamic reloading of filesystem cache size. Closes [#57866](https://github.com/ClickHouse/ClickHouse/issues/57866). [#57897](https://github.com/ClickHouse/ClickHouse/pull/57897) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Fix system.stack_trace for threads with blocked SIGRTMIN. [#57907](https://github.com/ClickHouse/ClickHouse/pull/57907) ([Azat Khuzhin](https://github.com/azat)).
|
||||

|
||||
* Add max/peak RSS (`MemoryResidentMax`) into system.asynchronous_metrics. [#58095](https://github.com/ClickHouse/ClickHouse/pull/58095) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fix system.stack_trace for threads with blocked SIGRTMIN (and also send signal to the threads only if it is not blocked to avoid waiting `storage_system_stack_trace_pipe_read_timeout_ms` when it does not make any sense). [#58136](https://github.com/ClickHouse/ClickHouse/pull/58136) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* This PR allows users to use s3 links (`https://` and `s3://`) without mentioning region if it's not default. Also find the correct region if the user mentioned the wrong one. ### Documentation entry for user-facing changes. [#58148](https://github.com/ClickHouse/ClickHouse/pull/58148) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
|
||||
* `clickhouse-format --obfuscate` will know about Settings, MergeTreeSettings, and time zones and keep their names unchanged. [#58179](https://github.com/ClickHouse/ClickHouse/pull/58179) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Added explicit `finalize()` function in `ZipArchiveWriter`. Simplify too complicated code in `ZipArchiveWriter`. This PR fixes [#58074](https://github.com/ClickHouse/ClickHouse/issues/58074). [#58202](https://github.com/ClickHouse/ClickHouse/pull/58202) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* The primary key analysis in MergeTree tables will now be applied to predicates that include the virtual column `_part_offset` (optionally with `_part`). This feature can serve as a poor man's secondary index. [#58224](https://github.com/ClickHouse/ClickHouse/pull/58224) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Make caches with the same path use the same cache objects. This behaviour existed before, but was broken in https://github.com/ClickHouse/ClickHouse/pull/48805 (in 23.4). If such caches with the same path have different set of cache settings, an exception will be thrown, that this is not allowed. [#58264](https://github.com/ClickHouse/ClickHouse/pull/58264) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement

||||
* Allow usage of Azure-related table engines/functions on macOS. [#51866](https://github.com/ClickHouse/ClickHouse/pull/51866) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* ClickHouse Fast Test now uses Musl instead of GLibc. [#57711](https://github.com/ClickHouse/ClickHouse/pull/57711) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Run ClickBench for every commit. This closes [#57708](https://github.com/ClickHouse/ClickHouse/issues/57708). [#57712](https://github.com/ClickHouse/ClickHouse/pull/57712) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
|
||||

|

sidebar_label: Build on Linux for s390x (zLinux)
|
||||
---
|
||||
|
||||
As of writing (2023/3/10) building for s390x considered to be experimental. Not all features can be enabled, has broken features and is currently under active development.
|
||||
|
||||
|
||||
## Building
|
||||
|
||||
As s390x does not support boringssl, it uses OpenSSL and has two related build options.
|
||||
- By default, the s390x build will dynamically link to OpenSSL libraries. It will build OpenSSL shared objects, so it's not necessary to install OpenSSL beforehand. (This option is recommended in all cases.)
|
||||
- Another option is to build OpenSSL in-tree. In this case two build flags need to be supplied to cmake
|
||||
```bash
|
||||
-DENABLE_OPENSSL_DYNAMIC=0 -DENABLE_OPENSSL=1
|
||||
```
|
||||
|
||||
These instructions assume that the host machine is x86_64 and has all the tooling required to build natively based on the [build instructions](../development/build.md). It also assumes that the host is Ubuntu 22.04 but the following instructions should also work on Ubuntu 20.04.
|
||||
|
||||
In addition to installing the tooling used to build natively, the following additional packages need to be installed:
|
||||
|
||||
```bash
|
||||
apt-get install binutils-s390x-linux-gnu libc6-dev-s390x-cross gcc-s390x-linux-gnu binfmt-support qemu-user-static
|
||||
```
|
||||
|
||||
If you wish to cross compile rust code install the rust cross compile target for s390x:
|
||||
```bash
|
||||
rustup target add s390x-unknown-linux-gnu
|
||||
```
|
||||
|
||||
To build for s390x:
|
||||
```bash
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=cmake/linux/toolchain-s390x.cmake ..
|
||||
ninja
|
||||
```
|
||||
|
||||
## Running
|
||||
|
||||
Once built, the binary can be run with, eg.:
|
||||
|
||||
```bash
|
||||
qemu-s390x-static -L /usr/s390x-linux-gnu ./clickhouse
|
||||
```
|
||||
|
||||
## Debugging
|
||||
|
||||
Install LLDB:
|
||||
|
||||
```bash
|
||||
apt-get install lldb-15
|
||||
```
|
||||
|
||||
To Debug a s390x executable, run clickhouse using QEMU in debug mode:
|
||||
|
||||
```bash
|
||||
qemu-s390x-static -g 31338 -L /usr/s390x-linux-gnu ./clickhouse
|
||||
```
|
||||
|
||||
In another shell run LLDB and attach, replace `<Clickhouse Parent Directory>` and `<build directory>` with the values corresponding to your environment.
|
||||
```bash
|
||||
lldb-15
|
||||
(lldb) target create ./clickhouse
|
||||
Current executable set to '/<Clickhouse Parent Directory>/ClickHouse/<build directory>/programs/clickhouse' (s390x).
|
||||
(lldb) settings set target.source-map <build directory> /<Clickhouse Parent Directory>/ClickHouse

|

```
|
||||
|
||||
## Visual Studio Code integration
|
||||
|
||||
- [CodeLLDB](https://github.com/vadimcn/vscode-lldb) extension is required for visual debugging.
|
||||
- [Command Variable](https://github.com/rioj7/command-variable) extension can help dynamic launches if using [CMake Variants](https://github.com/microsoft/vscode-cmake-tools/blob/main/docs/variants.md).
|
||||
- Make sure to set the backend to your LLVM installation eg. `"lldb.library": "/usr/lib/x86_64-linux-gnu/liblldb-15.so"`
|
||||
- Make sure to run the clickhouse executable in debug mode prior to launch. (It is also possible to create a `preLaunchTask` that automates this)
|

title: How to Build, Run and Debug ClickHouse on Linux for s390x (zLinux)
|

sidebar_label: Build on Linux for s390x (zLinux)
|
||||
---
|
||||
|
||||
As of writing (2023/3/10) building for s390x considered to be experimental. Not all features can be enabled, has broken features and is currently under active development.
|
||||
|
||||
|
||||
## Building
|
||||
|
||||
As s390x does not support boringssl, it uses OpenSSL and has two related build options.
|
||||
- By default, the s390x build will dynamically link to OpenSSL libraries. It will build OpenSSL shared objects, so it's not necessary to install OpenSSL beforehand. (This option is recommended in all cases.)
|
||||
- Another option is to build OpenSSL in-tree. In this case two build flags need to be supplied to cmake
|
||||
```bash
|
||||
-DENABLE_OPENSSL_DYNAMIC=0 -DENABLE_OPENSSL=1
|
||||
```
|
||||
|
||||
These instructions assume that the host machine is x86_64 and has all the tooling required to build natively based on the [build instructions](../development/build.md). It also assumes that the host is Ubuntu 22.04 but the following instructions should also work on Ubuntu 20.04.
|
||||
|
||||
In addition to installing the tooling used to build natively, the following additional packages need to be installed:
|
||||
|
||||
```bash
|
||||
apt-get install binutils-s390x-linux-gnu libc6-dev-s390x-cross gcc-s390x-linux-gnu binfmt-support qemu-user-static
|
||||
```
|
||||
|
||||
If you wish to cross compile rust code install the rust cross compile target for s390x:
|
||||
```bash
|
||||
rustup target add s390x-unknown-linux-gnu
|
||||
```
|
||||
|
||||
To build for s390x:
|
||||
```bash
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=cmake/linux/toolchain-s390x.cmake ..
|
||||
ninja
|
||||
```
|
||||
|
||||
## Running
|
||||
|
||||
Once built, the binary can be run with, eg.:
|
||||
|
||||
```bash
|
||||
qemu-s390x-static -L /usr/s390x-linux-gnu ./clickhouse
|
||||
```
|
||||
|
||||
## Debugging
|
||||
|
||||
Install LLDB:
|
||||
|
||||
```bash
|
||||
apt-get install lldb-15
|
||||
```
|
||||
|
||||
To Debug a s390x executable, run clickhouse using QEMU in debug mode:
|
||||
|
||||
```bash
|
||||
qemu-s390x-static -g 31338 -L /usr/s390x-linux-gnu ./clickhouse
|
||||
```
|
||||
|
||||
In another shell run LLDB and attach, replace `<Clickhouse Parent Directory>` and `<build directory>` with the values corresponding to your environment.
|
||||
```bash
|
||||
lldb-15
|
||||
(lldb) target create ./clickhouse
|
||||
Current executable set to '/<Clickhouse Parent Directory>/ClickHouse/<build directory>/programs/clickhouse' (s390x).
|
||||
(lldb) settings set target.source-map <build directory> /<Clickhouse Parent Directory>/ClickHouse

|
||||
|
||||
## Visual Studio Code integration
|
||||
|
||||
- [CodeLLDB](https://github.com/vadimcn/vscode-lldb) extension is required for visual debugging.
|
||||
- [Command Variable](https://github.com/rioj7/command-variable) extension can help dynamic launches if using [CMake Variants](https://github.com/microsoft/vscode-cmake-tools/blob/main/docs/variants.md).
|
||||
- Make sure to set the backend to your LLVM installation eg. `"lldb.library": "/usr/lib/x86_64-linux-gnu/liblldb-15.so"`
|
||||
- Make sure to run the clickhouse executable in debug mode prior to launch. (It is also possible to create a `preLaunchTask` that automates this)

### is_deleted
|
||||
|
||||
`is_deleted` — Name of a column used during a merge to determine whether the data in this row represents the state or is to be deleted; `1` is a “deleted“ row, `0` is a “state“ row.
|
||||
|
||||
Column data type — `UInt8`.
|
||||
|
||||
:::note
|
||||
`is_deleted` can only be enabled when `ver` is used.
|
||||
|
||||
The row is deleted when `OPTIMIZE ... FINAL CLEANUP` or `OPTIMIZE ... FINAL` is used, or if the engine setting `clean_deleted_rows` has been set to `Always`.
|
||||
|
||||
No matter the operation on the data, the version must be increased. If two inserted rows have the same version number, the last inserted row is the one kept.

# sparkbar
|
||||
|
||||
The function plots a frequency histogram for values `x` and the repetition rate `y` of these values over the interval `[min_x, max_x]`.
|
||||
Repetitions for all `x` falling into the same bucket are averaged, so data should be pre-aggregated.
|
||||
Negative repetitions are ignored.
|
||||
|
||||
If no interval is specified, then the minimum `x` is used as the interval start, and the maximum `x` — as the interval end.
|
||||
Otherwise, values outside the interval are ignored.
|
||||
|
||||
**Syntax**
|

Materialized views in ClickHouse use **column names** instead of column order during insertion into destination table. If some column names are not present in the `SELECT` query result, ClickHouse uses a default value, even if the column is not [Nullable](../../data-types/nullable.md). A safe practice would be to add aliases for every column when using Materialized views.
|
||||
|
||||
Materialized views in ClickHouse are implemented more like insert triggers. If there’s some aggregation in the view query, it’s applied only to the batch of freshly inserted data. Any changes to existing data of source table (like update, delete, drop partition, etc.) does not change the materialized view.

Periodically runs the corresponding query and stores its result in a table, atomically replacing the table's previous contents.
|
||||
|
||||
Differences from regular non-refreshable materialized views:
|
||||
* No insert trigger. I.e. when new data is inserted into the table specified in SELECT, it's *not* automatically pushed to the refreshable materialized view. The periodic refresh runs the entire query and replaces the entire table.
|
||||
* No restrictions on the SELECT query. Table functions (e.g. `url()`), views, UNION, JOIN, are all allowed.
|
||||
|
||||
:::note
|
||||
Refreshable materialized views are a work in progress. Setting `allow_experimental_refreshable_materialized_view = 1` is required for creating one. Current limitations:
|
||||
* not compatible with Replicated database or table engines,
|
||||
* require [Atomic database engine](../../../engines/database-engines/atomic.md),
|
||||
* no retries for failed refresh - we just skip to the next scheduled refresh time,
|
||||
* no limit on number of concurrent refreshes.
|
||||
:::
|
||||
|
||||
### Refresh Schedule
|
||||
|
||||
Example refresh schedules:
|
||||
```sql
|
||||
REFRESH EVERY 1 DAY -- every day, at midnight (UTC)
|
||||
REFRESH EVERY 1 MONTH -- on 1st day of every month, at midnight
|
||||
REFRESH EVERY 1 MONTH OFFSET 5 DAY 2 HOUR -- on 6th day of every month, at 2:00 am
|
||||
REFRESH EVERY 2 WEEK OFFSET 5 DAY 15 HOUR 10 MINUTE -- every other Saturday, at 3:10 pm
|
||||
REFRESH EVERY 30 MINUTE -- at 00:00, 00:30, 01:00, 01:30, etc
|
||||
REFRESH AFTER 30 MINUTE -- 30 minutes after the previous refresh completes, no alignment with time of day
|
||||
-- REFRESH AFTER 1 HOUR OFFSET 1 MINUTE -- syntax errror, OFFSET is not allowed with AFTER
|
||||
```
|
||||
|
||||
`RANDOMIZE FOR` randomly adjusts the time of each refresh, e.g.:
|
||||
```sql
|
||||
REFRESH EVERY 1 DAY OFFSET 2 HOUR RANDOMIZE FOR 1 HOUR -- every day at random time between 01:30 and 02:30
|
||||
```
|
||||
|
||||
At most one refresh may be running at a time, for a given view. E.g. if a view with `REFRESH EVERY 1 MINUTE` takes 2 minutes to refresh, it'll just be refreshing every 2 minutes. If it then becomes faster and starts refreshing in 10 seconds, it'll go back to refreshing every minute. (In particular, it won't refresh every 10 seconds to catch up with a backlog of missed refreshes - there's no such backlog.)
|
||||
|
||||
Additionally, a refresh is started immediately after the materialized view is created, unless `EMPTY` is specified in the `CREATE` query. If `EMPTY` is specified, the first refresh happens according to schedule.
|
||||
|
||||
### Dependencies {#refresh-dependencies}
|
||||
|
||||
`DEPENDS ON` synchronizes refreshes of different tables. By way of example, suppose there's a chain of two refreshable materialized views:
|
||||
```sql
|
||||
CREATE MATERIALIZED VIEW source REFRESH EVERY 1 DAY AS SELECT * FROM url(...)
|
||||
CREATE MATERIALIZED VIEW destination REFRESH EVERY 1 DAY AS SELECT ... FROM source
|
||||
```
|
||||
Without `DEPENDS ON`, both views will start a refresh at midnight, and `destination` typically will see yesterday's data in `source`. If we add dependency:
|
||||
```
|
||||
CREATE MATERIALIZED VIEW destination REFRESH EVERY 1 DAY DEPENDS ON source AS SELECT ... FROM source
|
||||
```
|
||||
then `destination`'s refresh will start only after `source`'s refresh finished for that day, so `destination` will be based on fresh data.
|
||||
|
||||
Alternatively, the same result can be achieved with:
|
||||
```
|
||||
CREATE MATERIALIZED VIEW destination REFRESH AFTER 1 HOUR DEPENDS ON source AS SELECT ... FROM source
|
||||
```
|
||||
where `1 HOUR` can be any duration less than `source`'s refresh period. The dependent table won't be refreshed more frequently than any of its dependencies. This is a valid way to set up a chain of refreshable views without specifying the real refresh period more than once.
|
||||
|
||||
A few more examples:
|
||||
* `REFRESH EVERY 1 DAY OFFSET 10 MINUTE` (`destination`) depends on `REFRESH EVERY 1 DAY` (`source`)<br/>
|
||||
If `source` refresh takes more than 10 minutes, `destination` will wait for it.
|
||||
* `REFRESH EVERY 1 DAY OFFSET 1 HOUR` depends on `REFRESH EVERY 1 DAY OFFSET 23 HOUR`<br/>
|
||||
Similar to the above, even though the corresponding refreshes happen on different calendar days.
|
||||
`destination`'s refresh on day X+1 will wait for `source`'s refresh on day X (if it takes more than 2 hours).
|
||||
* `REFRESH EVERY 2 HOUR` depends on `REFRESH EVERY 1 HOUR`<br/>
|
||||
The 2 HOUR refresh happens after the 1 HOUR refresh for every other hour, e.g. after the midnight
|
||||
refresh, then after the 2am refresh, etc.
|
||||
* `REFRESH EVERY 1 MINUTE` depends on `REFRESH EVERY 2 HOUR`<br/>
|
||||
`REFRESH AFTER 1 MINUTE` depends on `REFRESH EVERY 2 HOUR`<br/>
|
||||
`REFRESH AFTER 1 MINUTE` depends on `REFRESH AFTER 2 HOUR`<br/>
|
||||
`destination` is refreshed once after every `source` refresh, i.e. every 2 hours. The `1 MINUTE` is effectively ignored.
|
||||
* `REFRESH AFTER 1 HOUR` depends on `REFRESH AFTER 1 HOUR`<br/>
|
||||
Currently this is not recommended.
|
||||
|
||||
:::note
|
||||
`DEPENDS ON` only works between refreshable materialized views. Listing a regular table in the `DEPENDS ON` list will prevent the view from ever refreshing (dependencies can be removed with `ALTER`, see below).
|
||||
:::
|
||||
|
||||
### Changing Refresh Parameters {#changing-refresh-parameters}
|
||||
|
||||
To change refresh parameters:
|
||||
```
|
||||
ALTER TABLE [db.]name MODIFY REFRESH EVERY|AFTER ... [RANDOMIZE FOR ...] [DEPENDS ON ...]
|
||||
```
|
||||
|
||||
:::note
|
||||
This replaces refresh schedule *and* dependencies. If the table had a `DEPENDS ON`, doing a `MODIFY REFRESH` without `DEPENDS ON` will remove the dependencies.
|
||||
:::
|
||||
|
||||
### Other operations
|
||||
|
||||
The status of all refreshable materialized views is available in table [`system.view_refreshes`](../../../operations/system-tables/view_refreshes.md). In particular, it contains refresh progress (if running), last and next refresh time, exception message if a refresh failed.
|
||||
|
||||

`is_deleted` — Имя столбца, который используется во время слияния для обозначения того, нужно ли отображать строку или она подлежит удалению; `1` - для удаления строки, `0` - для отображения строки.
|
||||
|
||||
Тип данных столбца — `UInt8`.
|
||||
|
||||
:::note
|
||||
`is_deleted` может быть использован, если `ver` используется.
|
||||
|
||||
Строка удаляется в следующих случаях:
|
||||
|
||||
- при использовании инструкции `OPTIMIZE ... FINAL CLEANUP`
|
||||
- при использовании инструкции `OPTIMIZE ... FINAL`
|
||||
- параметр движка `clean_deleted_rows` установлен в значение `Always` (по умолчанию - `Never`)
|
||||
- есть новые версии строки
|
||||
|
||||
Не рекомендуется выполнять `FINAL CLEANUP` или использовать параметр движка `clean_deleted_rows` со значением `Always`, это может привести к неожиданным результатам, например удаленные строки могут вновь появиться.
|
||||
|
||||
Вне зависимости от производимых изменений над данными, версия должна увеличиваться. Если у двух строк одна и та же версия, то остается только последняя вставленная строка.

## Примеры {#examples}
|
||||
|
||||
1. Форматирование запроса:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --query "select number from numbers(10) where number%2 order by number desc;"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT number
|
||||
FROM numbers(10)
|
||||
WHERE number % 2
|
||||
ORDER BY number DESC
|
||||
```
|
||||
|
||||
2. Подсветка синтаксиса и форматирование в одну строку:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --oneline --hilite <<< "SELECT sum(number) FROM numbers(5);"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```sql
|
||||
SELECT sum(number) FROM numbers(5)
|
||||
```
|
||||
|
||||
3. Несколько запросов в одной строке:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format -n <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT *
|
||||
FROM
|
||||
(
|
||||
SELECT 1 AS x
|
||||
UNION ALL
|
||||
SELECT 1
|
||||
UNION DISTINCT
|
||||
SELECT 3
|
||||
)
|
||||
;
|
||||
```
|
||||
|
||||
4. Обфускация:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --seed Hello --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT treasury_mammoth_hazelnut BETWEEN nutmeg AND span, CASE WHEN chive >= 116 THEN switching ELSE ANYTHING END;
|
||||
```
|
||||
|
||||
Тот же запрос с другой инициализацией обфускатора:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --seed World --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT horse_tape_summer BETWEEN folklore AND moccasins, CASE WHEN intestine >= 116 THEN nonconformist ELSE FORESTRY END;
|
||||
```
|
||||
|
||||
5. Добавление обратного слеша:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --backslash <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT * \
|
||||
FROM \
|
||||
( \
|
||||

||||
|
||||
- `--help` или`-h` — выводит описание ключей.
|
||||
- `--query` — форматирует запрос любой длины и сложности.
|
||||
- `--hilite` — добавляет подсветку синтаксиса с экранированием символов.
|
||||
- `--oneline` — форматирование в одну строку.
|
||||
- `--quiet` или `-q` — проверяет синтаксис без вывода результата.
|
||||
- `--multiquery` or `-n` — поддерживает несколько запросов в одной строке.
|
||||
- `--obfuscate` — обфусцирует вместо форматирования.
|
||||
- `--seed <строка>` — задает строку, которая определяет результат обфускации.
|
||||
- `--backslash` — добавляет обратный слеш в конце каждой строки отформатированного запроса. Удобно использовать если многострочный запрос скопирован из интернета или другого источника и его нужно выполнить из командной строки.
|
||||
|
||||
## Примеры {#examples}
|
||||
|
||||
1. Форматирование запроса:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --query "select number from numbers(10) where number%2 order by number desc;"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT number
|
||||
FROM numbers(10)
|
||||
WHERE number % 2
|
||||
ORDER BY number DESC
|
||||
```
|
||||
|
||||
2. Подсветка синтаксиса и форматирование в одну строку:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --oneline --hilite <<< "SELECT sum(number) FROM numbers(5);"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```sql
|
||||
SELECT sum(number) FROM numbers(5)
|
||||
```
|
||||
|
||||
3. Несколько запросов в одной строке:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format -n <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT *
|
||||
FROM
|
||||
(
|
||||
SELECT 1 AS x
|
||||
UNION ALL
|
||||
SELECT 1
|
||||
UNION DISTINCT
|
||||
SELECT 3
|
||||
)
|
||||
;
|
||||
```
|
||||
|
||||
4. Обфускация:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --seed Hello --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT treasury_mammoth_hazelnut BETWEEN nutmeg AND span, CASE WHEN chive >= 116 THEN switching ELSE ANYTHING END;
|
||||
```
|
||||
|
||||
Тот же запрос с другой инициализацией обфускатора:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --seed World --obfuscate <<< "SELECT cost_first_screen BETWEEN a AND b, CASE WHEN x >= 123 THEN y ELSE NULL END;"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT horse_tape_summer BETWEEN folklore AND moccasins, CASE WHEN intestine >= 116 THEN nonconformist ELSE FORESTRY END;
|
||||
```
|
||||
|
||||
5. Добавление обратного слеша:
|
||||
|
||||
```bash
|
||||
$ clickhouse-format --backslash <<< "SELECT * FROM (SELECT 1 AS x UNION ALL SELECT 1 UNION DISTINCT SELECT 3);"
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
SELECT * \
|
||||
FROM \
|
||||
( \
|
||||
SELECT 1 AS x \
|
||||
UNION ALL \
|
||||
SELECT 1 \
|
||||
UNION DISTINCT \
|
||||
SELECT 3 \
|
||||
)
|
||||
```

Функция строит гистограмму частот по заданным значениям `x` и частоте повторения этих значений `y` на интервале `[min_x, max_x]`. Повторения для всех `x`, попавших в один бакет, усредняются, поэтому данные должны быть предварительно агрегированы. Отрицательные повторения игнорируются.
|
||||
|
||||
Если интервал для построения не указан, то в качестве нижней границы интервала будет взято минимальное значение `x`, а в качестве верхней границы — максимальное значение `x`.
|
||||
Значения `x` вне указанного интервала игнорируются.

它是“**点击**流”和“数据**仓库**”的组合。它来自于Yandex最初的用例。在Metrica网站上，ClickHouse本应该保存人们在互联网上的所有点击记录，现在它仍然在做这项工作。你可以在[ClickHouse history](../../introduction/history.md)页面上阅读更多关于这个用例的信息。
|
||||
|
||||
这个由两部分组成的意思有两个结果:
|
||||
|
||||
- 唯一正确的写“Click**H**ouse”的方式是用大写H。
|
||||
- 如果需要缩写，请使用“**CH**”。由于一些历史原因，缩写CK在中国也很流行，主要是因为中文中最早的一个关于ClickHouse的演讲使用了这种形式。

# ClickHouse支持多区域复制吗? {#does-clickhouse-support-multi-region-replication}
|
||||
|
||||
简短的回答是“是的”。然而，我们建议将所有区域/数据中心之间的延迟保持在两位数字范围内，否则，在通过分布式共识协议时，写性能将受到影响。例如，美国海岸之间的复制可能会很好，但美国和欧洲之间就不行。
|
||||
|
||||
在配置方面，这与单区域复制没有区别，只是使用位于不同位置的主机作为副本。
|
||||
|
||||
