# 2023 Changelog
### ClickHouse release 23.10, 2023-11-02
### <a id="2311"></a> ClickHouse release 23.11, 2023-12-06
#### Backward Incompatible Change
* The default ClickHouse server configuration file has enabled `access_management` (user manipulation by SQL queries) and `named_collection_control` (manipulation of named collection by SQL queries) for the `default` user by default. This closes [#56482](https://github.com/ClickHouse/ClickHouse/issues/56482). [#56619](https://github.com/ClickHouse/ClickHouse/pull/56619) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Multiple improvements for `RESPECT NULLS`/`IGNORE NULLS` for window functions. If you use them as aggregate functions and store the states of aggregate functions with these modifiers, they might become incompatible. [#57189](https://github.com/ClickHouse/ClickHouse/pull/57189) ([Raúl Marín](https://github.com/Algunenano)).
* Remove optimization `optimize_move_functions_out_of_any`. [#57190](https://github.com/ClickHouse/ClickHouse/pull/57190) ([Raúl Marín](https://github.com/Algunenano)).
* Formatters `%l`/`%k`/`%c` in function `parseDateTime` are now able to parse hours/months without leading zeros, e.g. `select parseDateTime('2023-11-26 8:14', '%F %k:%i')` now works. Set `parsedatetime_parse_without_leading_zeros = 0` to restore the previous behavior which required two digits. Function `formatDateTime` is now also able to print hours/months without leading zeros. This is controlled by setting `formatdatetime_format_without_leading_zeros` but off by default to not break existing use cases. [#55872](https://github.com/ClickHouse/ClickHouse/pull/55872) ([Azat Khuzhin](https://github.com/azat)).
* You can no longer use the aggregate function `avgWeighted` with arguments of type `Decimal`. Workaround: convert arguments to `Float64`. This closes [#43928](https://github.com/ClickHouse/ClickHouse/issues/43928). This closes [#31768](https://github.com/ClickHouse/ClickHouse/issues/31768). This closes [#56435](https://github.com/ClickHouse/ClickHouse/issues/56435). If you have used this function inside materialized views or projections with `Decimal` arguments, contact support@clickhouse.com. Fixed error in aggregate function `sumMap` and made it slower around 1.5..2 times. It does not matter because the function is garbage anyway. This closes [#54955](https://github.com/ClickHouse/ClickHouse/issues/54955). This closes [#53134](https://github.com/ClickHouse/ClickHouse/issues/53134). This closes [#55148](https://github.com/ClickHouse/ClickHouse/issues/55148). Fix a bug in function `groupArraySample` - it used the same random seed in case more than one aggregate state is generated in a query. [#56350](https://github.com/ClickHouse/ClickHouse/pull/56350) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
#### New Feature
* Added server setting `async_load_databases` for asynchronous loading of databases and tables. Speeds up the server start time. Applies to databases with `Ordinary`, `Atomic` and `Replicated` engines. Their tables load metadata asynchronously. Query to a table increases the priority of the load job and waits for it to be done. Added a new table `system.asynchronous_loader` for introspection. [#49351](https://github.com/ClickHouse/ClickHouse/pull/49351) ([Sergei Trifonov](https://github.com/serxa)).
* Add system table `blob_storage_log`. It allows auditing all the data written to S3 and other object storages. [#52918](https://github.com/ClickHouse/ClickHouse/pull/52918) ([vdimir](https://github.com/vdimir)).
* Use statistics to order prewhere conditions better. [#53240](https://github.com/ClickHouse/ClickHouse/pull/53240) ([Han Fei](https://github.com/hanfei1991)).
* Added support for compression in the Keeper's protocol. It can be enabled on the ClickHouse side by using this flag `use_compression` inside `zookeeper` section. Keep in mind that only ClickHouse Keeper supports compression, while Apache ZooKeeper does not. Resolves [#49507](https://github.com/ClickHouse/ClickHouse/issues/49507). [#54957](https://github.com/ClickHouse/ClickHouse/pull/54957) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
* Introduce the feature `storage_metadata_write_full_object_key`. If it is set as `true` then metadata files are written with the new format. With that format ClickHouse stores full remote object key in the metadata file which allows better flexibility and optimization. [#55566](https://github.com/ClickHouse/ClickHouse/pull/55566) ([Sema Checherinda](https://github.com/CheSema)).
* Add new settings and syntax to protect named collections' fields from being overridden. This is meant to prevent a malicious user from obtaining unauthorized access to secrets. [#55782](https://github.com/ClickHouse/ClickHouse/pull/55782) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
* Add `hostname` column to all system log tables - it is useful if you make the system tables replicated, shared, or distributed. [#55894](https://github.com/ClickHouse/ClickHouse/pull/55894) ([Bharat Nallan](https://github.com/bharatnc)).
* Add `CHECK ALL TABLES` query. [#56022](https://github.com/ClickHouse/ClickHouse/pull/56022) ([vdimir](https://github.com/vdimir)).
* Added function `fromDaysSinceYearZero` which is similar to MySQL's `FROM_DAYS`. E.g. `SELECT fromDaysSinceYearZero(739136)` returns `2023-09-08`. [#56088](https://github.com/ClickHouse/ClickHouse/pull/56088) ([Joanna Hulboj](https://github.com/jh0x)).
* Add an external Python tool to view backups and to extract information from them without using ClickHouse. [#56268](https://github.com/ClickHouse/ClickHouse/pull/56268) ([Vitaly Baranov](https://github.com/vitlibar)).
* Implement a new setting called `preferred_optimize_projection_name`. If it is set to a non-empty string, the specified projection would be used if possible instead of choosing from all the candidates. [#56309](https://github.com/ClickHouse/ClickHouse/pull/56309) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Add 4-letter command for yielding/resigning leadership (https://github.com/ClickHouse/ClickHouse/issues/56352). [#56354](https://github.com/ClickHouse/ClickHouse/pull/56354) ([Pradeep Chhetri](https://github.com/chhetripradeep)). [#56620](https://github.com/ClickHouse/ClickHouse/pull/56620) ([Pradeep Chhetri](https://github.com/chhetripradeep)).
* Added a new SQL function, `arrayRandomSample(arr, k)` which returns a sample of k elements from the input array. Similar functionality could previously be achieved only with less convenient syntax, e.g. `SELECT arrayReduce('groupArraySample(3)', range(10))`. [#56416](https://github.com/ClickHouse/ClickHouse/pull/56416) ([Robert Schulze](https://github.com/rschu1ze)).
* Added support for `Float16` type data to use in `.npy` files. Closes [#56344](https://github.com/ClickHouse/ClickHouse/issues/56344). [#56424](https://github.com/ClickHouse/ClickHouse/pull/56424) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Added a system view `information_schema.statistics` for better compatibility with Tableau Online. [#56425](https://github.com/ClickHouse/ClickHouse/pull/56425) ([Serge Klochkov](https://github.com/slvrtrn)).
* Add `system.symbols` table useful for introspection of the binary. [#56548](https://github.com/ClickHouse/ClickHouse/pull/56548) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Configurable dashboards. Queries for charts are now loaded using a query, which by default uses a new `system.dashboards` table. [#56771](https://github.com/ClickHouse/ClickHouse/pull/56771) ([Sergei Trifonov](https://github.com/serxa)).
* Introduce `fileCluster` table function - it is useful if you mount a shared filesystem (NFS and similar) into the `user_files` directory. [#56868](https://github.com/ClickHouse/ClickHouse/pull/56868) ([Andrey Zvonov](https://github.com/zvonand)).
* Add `_size` virtual column with file size in bytes to `s3/file/hdfs/url/azureBlobStorage` engines. [#57126](https://github.com/ClickHouse/ClickHouse/pull/57126) ([Kruglov Pavel](https://github.com/Avogar)).
* Expose the number of errors for each error code occurred on a server since last restart from the Prometheus endpoint. [#57209](https://github.com/ClickHouse/ClickHouse/pull/57209) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* ClickHouse keeper reports its running availability zone at `/keeper/availability-zone` path. This can be configured via `<availability_zone><value>us-west-1a</value></availability_zone>`. [#56715](https://github.com/ClickHouse/ClickHouse/pull/56715) ([Jianfei Hu](https://github.com/incfly)).
* Make ALTER materialized_view MODIFY QUERY non experimental and deprecate `allow_experimental_alter_materialized_view_structure` setting. Fixes [#15206](https://github.com/ClickHouse/ClickHouse/issues/15206). [#57311](https://github.com/ClickHouse/ClickHouse/pull/57311) ([alesapin](https://github.com/alesapin)).
* Setting `join_algorithm` respects specified order [#51745](https://github.com/ClickHouse/ClickHouse/pull/51745) ([vdimir](https://github.com/vdimir)).
* Add support for the [well-known Protobuf types](https://protobuf.dev/reference/protobuf/google.protobuf/) in the Protobuf format. [#56741](https://github.com/ClickHouse/ClickHouse/pull/56741) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
#### Performance Improvement
* Adaptive timeouts for interacting with S3. The first attempt is made with low send and receive timeouts. [#56314](https://github.com/ClickHouse/ClickHouse/pull/56314) ([Sema Checherinda](https://github.com/CheSema)).
* Increase the default value of `max_concurrent_queries` from 100 to 1000. This makes sense when there is a large number of connecting clients, which are slowly sending or receiving data, so the server is not limited by CPU, or when the number of CPU cores is larger than 100. Also, enable the concurrency control by default, and set the desired number of query processing threads in total as twice the number of CPU cores. It improves performance in scenarios with a very large number of concurrent queries. [#46927](https://github.com/ClickHouse/ClickHouse/pull/46927) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Support parallel evaluation of window functions. Fixes [#34688](https://github.com/ClickHouse/ClickHouse/issues/34688). [#39631](https://github.com/ClickHouse/ClickHouse/pull/39631) ([Dmitry Novik](https://github.com/novikd)).
* `Numbers` table engine (of the `system.numbers` table) now analyzes the condition to generate the needed subset of data, like table's index. [#50909](https://github.com/ClickHouse/ClickHouse/pull/50909) ([JackyWoo](https://github.com/JackyWoo)).
* Improved the performance of filtering by `IN (...)` condition for `Merge` table engine. [#54905](https://github.com/ClickHouse/ClickHouse/pull/54905) ([Nikita Taranov](https://github.com/nickitat)).
* An improvement which takes place when the filesystem cache is full and there are big reads. [#55158](https://github.com/ClickHouse/ClickHouse/pull/55158) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Add ability to disable checksums for S3 to avoid excessive pass over the file (this is controlled by the setting `s3_disable_checksum`). [#55559](https://github.com/ClickHouse/ClickHouse/pull/55559) ([Azat Khuzhin](https://github.com/azat)).
* Now we read synchronously from remote tables when data is in page cache (like we do for local tables). It is faster, it doesn't require synchronisation inside the thread pool, and doesn't hesitate to do `seek`-s on local FS, and reduces CPU wait. [#55841](https://github.com/ClickHouse/ClickHouse/pull/55841) ([Nikita Taranov](https://github.com/nickitat)).
* Optimization for getting value from `map`, `arrayElement`. It will bring about 30% speedup. - reduce the reserved memory - reduce the `resize` call. [#55957](https://github.com/ClickHouse/ClickHouse/pull/55957) ([lgbo](https://github.com/lgbo-ustc)).
* Optimization of multi-stage filtering with AVX-512. The performance experiments of the OnTime dataset on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) show that this change could bring the improvements of 7.4%, 5.9%, 4.7%, 3.0%, and 4.6% to the QPS of the query Q2, Q3, Q4, Q5 and Q6 respectively while having no impact on others. [#56079](https://github.com/ClickHouse/ClickHouse/pull/56079) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
* Limit the number of threads busy inside the query profiler. If there are more - they will skip profiling. [#56105](https://github.com/ClickHouse/ClickHouse/pull/56105) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Decrease the amount of virtual function calls in window functions. [#56120](https://github.com/ClickHouse/ClickHouse/pull/56120) ([Maksim Kita](https://github.com/kitaisreal)).
* Allow recursive Tuple field pruning in ORC data format to speed up scaning. [#56122](https://github.com/ClickHouse/ClickHouse/pull/56122) ([李扬](https://github.com/taiyang-li)).
* Trivial count optimization for `Npy` data format: queries like `select count() from 'data.npy'` will work much more fast because of caching the results. [#56304](https://github.com/ClickHouse/ClickHouse/pull/56304) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Queries with aggregation and a large number of streams will use less amount of memory during the plan's construction. [#57074](https://github.com/ClickHouse/ClickHouse/pull/57074) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Improve performance of executing queries for use cases with many users and highly concurrent queries (>2000 QPS) by optimizing the access to ProcessList. [#57106](https://github.com/ClickHouse/ClickHouse/pull/57106) ([Andrej Hoos](https://github.com/adikus)).
* Trivial improvement on array join, reuse some intermediate results. [#57183](https://github.com/ClickHouse/ClickHouse/pull/57183) ([李扬](https://github.com/taiyang-li)).
* There are cases when stack unwinding was slow. Not anymore. [#57221](https://github.com/ClickHouse/ClickHouse/pull/57221) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Now we use default read pool for reading from external storage when `max_streams = 1`. It is beneficial when read prefetches are enabled. [#57334](https://github.com/ClickHouse/ClickHouse/pull/57334) ([Nikita Taranov](https://github.com/nickitat)).
* Keeper improvement: improve memory-usage during startup by delaying log preprocessing. [#55660](https://github.com/ClickHouse/ClickHouse/pull/55660) ([Antonio Andelic](https://github.com/antonio2368)).
* Improved performance of glob matching for `File` and `HDFS` storages. [#56141](https://github.com/ClickHouse/ClickHouse/pull/56141) ([Andrey Zvonov](https://github.com/zvonand)).
* Posting lists in experimental full text indexes are now compressed which reduces their size by 10-30%. [#56226](https://github.com/ClickHouse/ClickHouse/pull/56226) ([Harry Lee](https://github.com/HarryLeeIBM)).
* Parallelise `BackupEntriesCollector` in backups. [#56312](https://github.com/ClickHouse/ClickHouse/pull/56312) ([Kseniia Sumarokova](https://github.com/kssenii)).
#### Improvement
* Add a new `MergeTree` setting `add_implicit_sign_column_constraint_for_collapsing_engine` (disabled by default). When enabled, it adds an implicit CHECK constraint for `CollapsingMergeTree` tables that restricts the value of the `Sign` column to be only -1 or 1. [#56701](https://github.com/ClickHouse/ClickHouse/issues/56701). [#56986](https://github.com/ClickHouse/ClickHouse/pull/56986) ([Kevin Mingtarja](https://github.com/kevinmingtarja)).
* Enable adding new disk to storage configuration without restart. [#56367](https://github.com/ClickHouse/ClickHouse/pull/56367) ([Duc Canh Le](https://github.com/canhld94)).
* Support creating and materializing index in the same alter query, also support "modify TTL" and "materialize TTL" in the same query. Closes [#55651](https://github.com/ClickHouse/ClickHouse/issues/55651). [#56331](https://github.com/ClickHouse/ClickHouse/pull/56331) ([flynn](https://github.com/ucasfl)).
* Add a new table function named `fuzzJSON` with rows containing perturbed versions of the source JSON string with random variations. [#56490](https://github.com/ClickHouse/ClickHouse/pull/56490) ([Julia Kartseva](https://github.com/jkartseva)).
* Engine `Merge` filters the records according to the row policies of the underlying tables, so you don't have to create another row policy on a `Merge` table. [#50209](https://github.com/ClickHouse/ClickHouse/pull/50209) ([Ilya Golshtein](https://github.com/ilejn)).
* Add a setting `max_execution_time_leaf` to limit the execution time on shard for distributed query, and `timeout_overflow_mode_leaf` to control the behaviour if timeout happens. [#51823](https://github.com/ClickHouse/ClickHouse/pull/51823) ([Duc Canh Le](https://github.com/canhld94)).
* Add ClickHouse setting to disable tunneling for HTTPS requests over HTTP proxy. [#55033](https://github.com/ClickHouse/ClickHouse/pull/55033) ([Arthur Passos](https://github.com/arthurpassos)).
* Set `background_fetches_pool_size` to 16, background_schedule_pool_size to 512 that is better for production usage with frequent small insertions. [#54327](https://github.com/ClickHouse/ClickHouse/pull/54327) ([Denny Crane](https://github.com/den-crane)).
* While read data from a csv format file, and at end of line is `\r` , which not followed by `\n`, then we will enconter the exception as follows `Cannot parse CSV format: found \r (CR) not followed by \n (LF). Line must end by \n (LF) or \r\n (CR LF) or \n\r.` In clickhouse, the csv end of line must be `\n` or `\r\n` or `\n\r`, so the `\r` must be followed by `\n`, but in some suitation, the csv input data is abnormal, like above, `\r` is at end of line. [#54340](https://github.com/ClickHouse/ClickHouse/pull/54340) ([KevinyhZou](https://github.com/KevinyhZou)).
* Update Arrow library to release-13.0.0 that supports new encodings. Closes [#44505](https://github.com/ClickHouse/ClickHouse/issues/44505). [#54800](https://github.com/ClickHouse/ClickHouse/pull/54800) ([Kruglov Pavel](https://github.com/Avogar)).
* Improve performance of ON CLUSTER queries by removing heavy system calls to get all network interfaces when looking for local ip address in the DDL entry hosts list. [#54909](https://github.com/ClickHouse/ClickHouse/pull/54909) ([Duc Canh Le](https://github.com/canhld94)).
* Fixed accounting of memory allocated before attaching a thread to a query or a user. [#56089](https://github.com/ClickHouse/ClickHouse/pull/56089) ([Nikita Taranov](https://github.com/nickitat)).
* Add support for `LARGE_LIST` in Apache Arrow formats. [#56118](https://github.com/ClickHouse/ClickHouse/pull/56118) ([edef](https://github.com/edef1c)).
* Allow manual compaction of `EmbeddedRocksDB` via `OPTIMIZE` query. [#56225](https://github.com/ClickHouse/ClickHouse/pull/56225) ([Azat Khuzhin](https://github.com/azat)).
* Add ability to specify BlockBasedTableOptions for `EmbeddedRocksDB` tables. [#56264](https://github.com/ClickHouse/ClickHouse/pull/56264) ([Azat Khuzhin](https://github.com/azat)).
* `SHOW COLUMNS` now displays MySQL's equivalent data type name when the connection was made through the MySQL protocol. Previously, this was the case when setting `use_mysql_types_in_show_columns = 1`. The setting is retained but made obsolete. [#56277](https://github.com/ClickHouse/ClickHouse/pull/56277) ([Robert Schulze](https://github.com/rschu1ze)).
* Fixed possible `The local set of parts of table doesn't look like the set of parts in ZooKeeper` error if server was restarted just after `TRUNCATE` or `DROP PARTITION`. [#56282](https://github.com/ClickHouse/ClickHouse/pull/56282) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Fixed handling of non-const query strings in functions `formatQuery`/ `formatQuerySingleLine`. Also added `OrNull` variants of both functions that return a NULL when a query cannot be parsed instead of throwing an exception. [#56327](https://github.com/ClickHouse/ClickHouse/pull/56327) ([Robert Schulze](https://github.com/rschu1ze)).
* Allow backup of materialized view with dropped inner table instead of failing the backup. [#56387](https://github.com/ClickHouse/ClickHouse/pull/56387) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Queries to `system.replicas` initiate requests to ZooKeeper when certain columns are queried. When there are thousands of tables these requests might produce a considerable load on ZooKeeper. If there are multiple simultaneous queries to `system.replicas` they do same requests multiple times. The change is to "deduplicate" requests from concurrent queries. [#56420](https://github.com/ClickHouse/ClickHouse/pull/56420) ([Alexander Gololobov](https://github.com/davenger)).
* Fix translation to MySQL compatible query for querying external databases. [#56456](https://github.com/ClickHouse/ClickHouse/pull/56456) ([flynn](https://github.com/ucasfl)).
* Add support for backing up and restoring tables using `KeeperMap` engine. [#56460](https://github.com/ClickHouse/ClickHouse/pull/56460) ([Antonio Andelic](https://github.com/antonio2368)).
* 404 response for CompleteMultipartUpload has to be rechecked. Operation could be done on server even if client got timeout or other network errors. The next retry of CompleteMultipartUpload receives 404 response. If the object key exists that operation is considered as successful. [#56475](https://github.com/ClickHouse/ClickHouse/pull/56475) ([Sema Checherinda](https://github.com/CheSema)).
* Enable the HTTP OPTIONS method by default - it simplifies requesting ClickHouse from a web browser. [#56483](https://github.com/ClickHouse/ClickHouse/pull/56483) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* The value for `dns_max_consecutive_failures` was changed by mistake in [#46550](https://github.com/ClickHouse/ClickHouse/issues/46550) - this is reverted and adjusted to a better value. Also, increased the HTTP keep-alive timeout to a reasonable value from production. [#56485](https://github.com/ClickHouse/ClickHouse/pull/56485) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Load base backups lazily (a base backup won't be loaded until it's needed). Also add some log message and profile events for backups. [#56516](https://github.com/ClickHouse/ClickHouse/pull/56516) ([Vitaly Baranov](https://github.com/vitlibar)).
* Setting `query_cache_store_results_of_queries_with_nondeterministic_functions` (with values `false` or `true`) was marked obsolete. It was replaced by setting `query_cache_nondeterministic_function_handling`, a three-valued enum that controls how the query cache handles queries with non-deterministic functions: a) throw an exception (default behavior), b) save the non-deterministic query result regardless, or c) ignore, i.e. don't throw an exception and don't cache the result. [#56519](https://github.com/ClickHouse/ClickHouse/pull/56519) ([Robert Schulze](https://github.com/rschu1ze)).
* Rewrite equality with `is null` check in JOIN ON section. Experimental *Analyzer only*. [#56538](https://github.com/ClickHouse/ClickHouse/pull/56538) ([vdimir](https://github.com/vdimir)).
* Function`concat` now supports arbitrary argument types (instead of only String and FixedString arguments). This makes it behave more similar to MySQL `concat` implementation. For example, `SELECT concat('ab', 42)` now returns `ab42`. [#56540](https://github.com/ClickHouse/ClickHouse/pull/56540) ([Serge Klochkov](https://github.com/slvrtrn)).
* Allow getting cache configuration from 'named_collection' section in config or from SQL created named collections. [#56541](https://github.com/ClickHouse/ClickHouse/pull/56541) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Update `query_masking_rules` when reloading the config ([#56449](https://github.com/ClickHouse/ClickHouse/issues/56449)). [#56573](https://github.com/ClickHouse/ClickHouse/pull/56573) ([Mikhail Koviazin](https://github.com/mkmkme)).
* PostgreSQL database engine: Make the removal of outdated tables less aggressive with unsuccessful postgres connection. [#56609](https://github.com/ClickHouse/ClickHouse/pull/56609) ([jsc0218](https://github.com/jsc0218)).
* It took too much time to connnect to PG when URL is not right, so the relevant query stucks there and get cancelled. [#56648](https://github.com/ClickHouse/ClickHouse/pull/56648) ([jsc0218](https://github.com/jsc0218)).
* Keeper improvement: disable compressed logs by default in Keeper. [#56763](https://github.com/ClickHouse/ClickHouse/pull/56763) ([Antonio Andelic](https://github.com/antonio2368)).
* Add config setting `wait_dictionaries_load_at_startup`. [#56782](https://github.com/ClickHouse/ClickHouse/pull/56782) ([Vitaly Baranov](https://github.com/vitlibar)).
* There was a potential vulnerability in previous ClickHouse versions: if a user has connected and unsuccessfully tried to authenticate with the "interserver secret" method, the server didn't terminate the connection immediately but continued to receive and ignore the leftover packets from the client. While these packets are ignored, they are still parsed, and if they use a compression method with another known vulnerability, it will lead to exploitation of it without authentication. This issue was found with [ClickHouse Bug Bounty Program](https://github.com/ClickHouse/ClickHouse/issues/38986) by https://twitter.com/malacupa. [#56794](https://github.com/ClickHouse/ClickHouse/pull/56794) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fetching a part waits when that part is fully committed on remote replica. It is better not send part in PreActive state. In case of zero copy this is mandatory restriction. [#56808](https://github.com/ClickHouse/ClickHouse/pull/56808) ([Sema Checherinda](https://github.com/CheSema)).
* Fix possible postgresql logical replication conversion error when using experimental `MaterializedPostgreSQL`. [#53721](https://github.com/ClickHouse/ClickHouse/pull/53721) ([takakawa](https://github.com/takakawa)).
* Implement user-level setting `alter_move_to_space_execute_async` which allow to execute queries `ALTER TABLE ... MOVE PARTITION|PART TO DISK|VOLUME` asynchronously. The size of pool for background executions is controlled by `background_move_pool_size`. Default behavior is synchronous execution. Fixes [#47643](https://github.com/ClickHouse/ClickHouse/issues/47643). [#56809](https://github.com/ClickHouse/ClickHouse/pull/56809) ([alesapin](https://github.com/alesapin)).
* Able to filter by engine when scanning system.tables, avoid unnecessary (potentially time-consuming) connection. [#56813](https://github.com/ClickHouse/ClickHouse/pull/56813) ([jsc0218](https://github.com/jsc0218)).
* Show `total_bytes` and `total_rows` in system tables for RocksDB storage. [#56816](https://github.com/ClickHouse/ClickHouse/pull/56816) ([Aleksandr Musorin](https://github.com/AVMusorin)).
* Allow basic commands in ALTER for TEMPORARY tables. [#56892](https://github.com/ClickHouse/ClickHouse/pull/56892) ([Sergey](https://github.com/icuken)).
* LZ4 compression. Buffer compressed block in a rare case when out buffer capacity is not enough for writing compressed block directly to out's buffer. [#56938](https://github.com/ClickHouse/ClickHouse/pull/56938) ([Sema Checherinda](https://github.com/CheSema)).
* Add metrics for the number of queued jobs, which is useful for the IO thread pool. [#56958](https://github.com/ClickHouse/ClickHouse/pull/56958) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add a setting for PostgreSQL table engine setting in the config file. Added a check for the setting Added documentation around the additional setting. [#56959](https://github.com/ClickHouse/ClickHouse/pull/56959) ([Peignon Melvyn](https://github.com/melvynator)).
* Function `concat` can now be called with a single argument, e.g., `SELECT concat('abc')`. This makes its behavior more consistent with MySQL's concat implementation. [#57000](https://github.com/ClickHouse/ClickHouse/pull/57000) ([Serge Klochkov](https://github.com/slvrtrn)).
* Signs all `x-amz-*` headers as required by AWS S3 docs. [#57001](https://github.com/ClickHouse/ClickHouse/pull/57001) ([Arthur Passos](https://github.com/arthurpassos)).
* Function `fromDaysSinceYearZero` (alias: `FROM_DAYS`) can now be used with unsigned and signed integer types (previously, it had to be an unsigned integer). This improve compatibility with 3rd party tools such as Tableau Online. [#57002](https://github.com/ClickHouse/ClickHouse/pull/57002) ([Serge Klochkov](https://github.com/slvrtrn)).
* Add `system.s3queue_log` to default config. [#57036](https://github.com/ClickHouse/ClickHouse/pull/57036) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Change the default for `wait_dictionaries_load_at_startup` to true, and use this setting only if `dictionaries_lazy_load` is false. [#57133](https://github.com/ClickHouse/ClickHouse/pull/57133) ([Vitaly Baranov](https://github.com/vitlibar)).
* Check dictionary source type on creation even if `dictionaries_lazy_load` is enabled. [#57134](https://github.com/ClickHouse/ClickHouse/pull/57134) ([Vitaly Baranov](https://github.com/vitlibar)).
* Plan-level optimizations can now be enabled/disabled individually. Previously, it was only possible to disable them all. The setting which previously did that (`query_plan_enable_optimizations`) is retained and can still be used to disable all optimizations. [#57152](https://github.com/ClickHouse/ClickHouse/pull/57152) ([Robert Schulze](https://github.com/rschu1ze)).
* The server's exit code will correspond to the exception code. For example, if the server cannot start due to memory limit, it will exit with the code 241 = MEMORY_LIMIT_EXCEEDED. In previous versions, the exit code for exceptions was always 70 = Poco::Util::ExitCode::EXIT_SOFTWARE. [#57153](https://github.com/ClickHouse/ClickHouse/pull/57153) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Do not demangle and symbolize stack frames from `functional` C++ header. [#57201](https://github.com/ClickHouse/ClickHouse/pull/57201) ([Mike Kot](https://github.com/myrrc)).
* HTTP server page `/dashboard` now supports charts with multiple lines. [#57236](https://github.com/ClickHouse/ClickHouse/pull/57236) ([Sergei Trifonov](https://github.com/serxa)).
* The `max_memory_usage_in_client` command line option supports a string value with a suffix (K, M, G, etc). Closes [#56879](https://github.com/ClickHouse/ClickHouse/issues/56879). [#57273](https://github.com/ClickHouse/ClickHouse/pull/57273) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Bumped Intel QPL (used by codec `DEFLATE_QPL`) from v1.2.0 to v1.3.1 . Also fixed a bug in case of BOF (Block On Fault) = 0, changed to handle page faults by falling back to SW path. [#57291](https://github.com/ClickHouse/ClickHouse/pull/57291) ([jasperzhu](https://github.com/jinjunzh)).
* Increase default `replicated_deduplication_window` of MergeTree settings from 100 to 1k. [#57335](https://github.com/ClickHouse/ClickHouse/pull/57335) ([sichenzhao](https://github.com/sichenzhao)).
* Stop using `INCONSISTENT_METADATA_FOR_BACKUP` that much. If possible prefer to continue scanning instead of stopping and starting the scanning for backup from the beginning. [#57385](https://github.com/ClickHouse/ClickHouse/pull/57385) ([Vitaly Baranov](https://github.com/vitlibar)).
#### Build/Testing/Packaging Improvement
* Add SQLLogic test. [#56078](https://github.com/ClickHouse/ClickHouse/pull/56078) ([Han Fei](https://github.com/hanfei1991)).
* Make `clickhouse-local` and `clickhouse-client` available under short names (`ch`, `chl`, `chc`) for usability. [#56634](https://github.com/ClickHouse/ClickHouse/pull/56634) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Optimized build size further by removing unused code from external libraries. [#56786](https://github.com/ClickHouse/ClickHouse/pull/56786) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add automatic check that there are no large translation units. [#56559](https://github.com/ClickHouse/ClickHouse/pull/56559) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Lower the size of the single-binary distribution. This closes [#55181](https://github.com/ClickHouse/ClickHouse/issues/55181). [#56617](https://github.com/ClickHouse/ClickHouse/pull/56617) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Information about the sizes of every translation unit and binary file after each build will be sent to the CI database in ClickHouse Cloud. This closes [#56107](https://github.com/ClickHouse/ClickHouse/issues/56107). [#56636](https://github.com/ClickHouse/ClickHouse/pull/56636) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Certain files of "Apache Arrow" library (which we use only for non-essential things like parsing the arrow format) were rebuilt all the time regardless of the build cache. This is fixed. [#56657](https://github.com/ClickHouse/ClickHouse/pull/56657) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Avoid recompiling translation units depending on the autogenerated source file about version. [#56660](https://github.com/ClickHouse/ClickHouse/pull/56660) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Tracing data of the linker invocations will be sent to the CI database in ClickHouse Cloud. [#56725](https://github.com/ClickHouse/ClickHouse/pull/56725) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

* Add a new build option `SANITIZE_COVERAGE`. If it is enabled, the code is instrumented to track the coverage. The collected information is available inside ClickHouse with: (1) a new function `coverage` that returns an array of unique addresses in the code found after the previous coverage reset; (2) `SYSTEM RESET COVERAGE` query that resets the accumulated data. This allows us to compare the coverage of different tests, including differential code coverage. Continuation of [#20539](https://github.com/ClickHouse/ClickHouse/issues/20539). [#56102](https://github.com/ClickHouse/ClickHouse/pull/56102) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Some of the stack frames might not be resolved when collecting stacks. In such cases the raw address might be helpful. [#56267](https://github.com/ClickHouse/ClickHouse/pull/56267) ([Alexander Gololobov](https://github.com/davenger)).
* Add an option to disable `libssh`. [#56333](https://github.com/ClickHouse/ClickHouse/pull/56333) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

### <a id="2310"></a> ClickHouse release 23.10, 2023-11-02
#### Backward Incompatible Change

* Allow to save unparsed records and errors in RabbitMQ, NATS and FileLog engines. Add virtual columns `_error` and `_raw_message`(for NATS and RabbitMQ), `_raw_record` (for FileLog) that are filled when ClickHouse fails to parse new record. The behaviour is controlled under storage settings `nats_handle_error_mode` for NATS, `rabbitmq_handle_error_mode` for RabbitMQ, `handle_error_mode` for FileLog similar to `kafka_handle_error_mode`. If it's set to `default`, en exception will be thrown when ClickHouse fails to parse a record, if it's set to `stream`, erorr and raw record will be saved into virtual columns.

# 2023 Changelog
### ClickHouse release v23.11.1.2711-stable (05bc8ef1e02) FIXME as compared to v23.10.1.1976-stable (13adae0e42f)
#### Backward Incompatible Change
* Formatters `%l`/`%k`/`%c` in function `parseDateTime()` are now able to parse hours/months without leading zeros, e.g. `select parseDateTime('2023-11-26 8:14', '%F %k:%i')` now works. Set `parsedatetime_parse_without_leading_zeros = 0` to restore the previous behavior which required two digits. Function `formatDateTime` is now also able to print hours/months without leading zeros. This is controlled by setting `formatdatetime_format_without_leading_zeros` but off by default to not break existing use cases. [#55872](https://github.com/ClickHouse/ClickHouse/pull/55872) ([Azat Khuzhin](https://github.com/azat)).
* You can no longer use the aggregate function `avgWeighted` with arguments of type `Decimal`. Workaround: convert arguments to `Float64`. This closes [#43928](https://github.com/ClickHouse/ClickHouse/issues/43928). This closes [#31768](https://github.com/ClickHouse/ClickHouse/issues/31768). This closes [#56435](https://github.com/ClickHouse/ClickHouse/issues/56435). If you have used this function inside materialized views or projections with `Decimal` arguments, contact support@clickhouse.com. Fixed error in aggregate function `sumMap` and made it slower around 1.5..2 times. It does not matter because the function is garbage anyway. This closes [#54955](https://github.com/ClickHouse/ClickHouse/issues/54955). This closes [#53134](https://github.com/ClickHouse/ClickHouse/issues/53134). This closes [#55148](https://github.com/ClickHouse/ClickHouse/issues/55148). Fix a bug in function `groupArraySample` - it used the same random seed in case more than one aggregate state is generated in a query. [#56350](https://github.com/ClickHouse/ClickHouse/pull/56350) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* The default ClickHouse server configuration file has enabled `access_management` (user manipulation by SQL queries) and `named_collection_control` (manipulation of named collection by SQL queries) for the `default` user by default. This closes [#56482](https://github.com/ClickHouse/ClickHouse/issues/56482). [#56619](https://github.com/ClickHouse/ClickHouse/pull/56619) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Multiple improvements for RESPECT/IGNORE NULLS. [#57189](https://github.com/ClickHouse/ClickHouse/pull/57189) ([Raúl Marín](https://github.com/Algunenano)).
* Remove optimization optimize_move_functions_out_of_any. [#57190](https://github.com/ClickHouse/ClickHouse/pull/57190) ([Raúl Marín](https://github.com/Algunenano)).
#### New Feature
* Added server setting `async_load_databases` for asynchronous loading of databases and tables. Speeds up the server start time. Applies to databases with Ordinary, Atomic and Replicated engines. Their tables load metadata asynchronously. Query to a table increases the priority of the load job and waits for it to be done. Added table `system.async_loader`. [#49351](https://github.com/ClickHouse/ClickHouse/pull/49351) ([Sergei Trifonov](https://github.com/serxa)).
* 1. Add function `extractPlainRanges` to `KeyCondition`. 2. Add some useful functions to `Range` 3. Add `PlainRanges` who represent a serious of ranges that ordered and no overlapping. 4. Add `NumbersRangedSource` who can accurately return user selected numbers. [#50909](https://github.com/ClickHouse/ClickHouse/pull/50909) ([JackyWoo](https://github.com/JackyWoo)).
* Add system table `blob_storage_log`. [#52918](https://github.com/ClickHouse/ClickHouse/pull/52918) ([vdimir](https://github.com/vdimir)).
* Use statistic to order prewhere conditions better. [#53240](https://github.com/ClickHouse/ClickHouse/pull/53240) ([Han Fei](https://github.com/hanfei1991)).
* Added a new aggregation function `groupArraySorted(n)(value)` which returns an array with the n first values from a field value sorted by itself. [#53562](https://github.com/ClickHouse/ClickHouse/pull/53562) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Added support for compression in keeper protocol. Can be enabled on clickhouse by using this flag `use_compression` inside `zookeeper`. resolves [#49507](https://github.com/ClickHouse/ClickHouse/issues/49507). [#54957](https://github.com/ClickHouse/ClickHouse/pull/54957) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
* Add ClickHouse setting to disable tunneling for HTTPS requests over HTTP proxy. [#55033](https://github.com/ClickHouse/ClickHouse/pull/55033) ([Arthur Passos](https://github.com/arthurpassos)).
* Introduce the feature `storage_metadata_write_full_object_key`. If it is set as `true` then metadata files are written with new format VERSION_FULL_OBJECT_KEY. With that format CH stores full remote object key in the metadata file. [#55566](https://github.com/ClickHouse/ClickHouse/pull/55566) ([Sema Checherinda](https://github.com/CheSema)).
* Add new settings and syntax to protect named collections' fields from being overridden. This is meant to prevent a malicious user from obtaining unauthorized access to secrets. [#55782](https://github.com/ClickHouse/ClickHouse/pull/55782) ([Salvatore Mesoraca](https://github.com/aiven-sal)).
* Add `hostname` column to all system log tables;. [#55894](https://github.com/ClickHouse/ClickHouse/pull/55894) ([Bharat Nallan](https://github.com/bharatnc)).
* Add `CHECK ALL TABLES` query. [#56022](https://github.com/ClickHouse/ClickHouse/pull/56022) ([vdimir](https://github.com/vdimir)).
* Added function `fromDaysSinceYearZero()` which is similar to MySQL's `FROM_DAYS`. E.g. `SELECT fromDaysSinceYearZero(739136)` returns `2023-09-08`. [#56088](https://github.com/ClickHouse/ClickHouse/pull/56088) ([Joanna Hulboj](https://github.com/jh0x)).
* Implemented series period detect method using FFT in pocketFFT lib. [#56171](https://github.com/ClickHouse/ClickHouse/pull/56171) ([Bhavna Jindal](https://github.com/bhavnajindal)).
* Add an external Python tool to view backups and to extract information from them without using ClickHouse. [#56268](https://github.com/ClickHouse/ClickHouse/pull/56268) ([Vitaly Baranov](https://github.com/vitlibar)).
* ... [#56275](https://github.com/ClickHouse/ClickHouse/pull/56275) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* This pull request implements new setting called `preferred_projection_name`. If it is set to a non-empty string, the specified projection would be used if possible. [#56309](https://github.com/ClickHouse/ClickHouse/pull/56309) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* S3 adaptive timeout means that first attempt made with low send and receive timeouts. [#56314](https://github.com/ClickHouse/ClickHouse/pull/56314) ([Sema Checherinda](https://github.com/CheSema)).
* Add 4-letter command for yielding/resigning leadership (https://github.com/ClickHouse/ClickHouse/issues/56352). [#56354](https://github.com/ClickHouse/ClickHouse/pull/56354) ([Pradeep Chhetri](https://github.com/chhetripradeep)).
* Added a new SQL function, "arrayRandomSample(arr, k)" which returns a sample of k elements from the input array. Similar functionality could previously be achieved only with less convenient syntax, e.g. "SELECT arrayReduce('groupArraySample(3)', range(10))". [#56416](https://github.com/ClickHouse/ClickHouse/pull/56416) ([Robert Schulze](https://github.com/rschu1ze)).
* Added support for `float16` type data to use in `.npy` files. Closes [#56344](https://github.com/ClickHouse/ClickHouse/issues/56344). [#56424](https://github.com/ClickHouse/ClickHouse/pull/56424) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Added system view `information_schema.statistics` for better compatibility with Tableau Online. [#56425](https://github.com/ClickHouse/ClickHouse/pull/56425) ([Serge Klochkov](https://github.com/slvrtrn)).
* Add function `getClientHTTPHeader` for fetching values header values set in the HTTP request. [#56488](https://github.com/ClickHouse/ClickHouse/pull/56488) ([凌涛](https://github.com/lingtaolf)).
* Add a new table function named `fuzzJSON` with rows containing perturbed versions of the source JSON string with random variations. [#56490](https://github.com/ClickHouse/ClickHouse/pull/56490) ([Julia Kartseva](https://github.com/jkartseva)).
* Add `system.symbols` table useful for introspection of the binary. [#56548](https://github.com/ClickHouse/ClickHouse/pull/56548) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add 4-letter command for yielding/resigning leadership. [#56620](https://github.com/ClickHouse/ClickHouse/pull/56620) ([Pradeep Chhetri](https://github.com/chhetripradeep)).
* Configurable dashboards. Queries for charts are now loaded using a query, which by default uses a new `system.dashboards` table. [#56771](https://github.com/ClickHouse/ClickHouse/pull/56771) ([Sergei Trifonov](https://github.com/serxa)).
* Introduce `fileCluster` table function. [#56868](https://github.com/ClickHouse/ClickHouse/pull/56868) ([Andrey Zvonov](https://github.com/zvonand)).
* Add `_size` virtual column with file size in bytes to `s3/file/hdfs/url/azureBlobStorage` engines. [#57126](https://github.com/ClickHouse/ClickHouse/pull/57126) ([Kruglov Pavel](https://github.com/Avogar)).
* Expose the number of errors occurred on a server since last restart from the Prometheus endpoint. [#57209](https://github.com/ClickHouse/ClickHouse/pull/57209) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Added a new SQL function `sqid` to generate Sqids (https://sqids.org/), example: `SELECT sqid(125, 126)`. [#57442](https://github.com/ClickHouse/ClickHouse/pull/57442) ([awakeljw](https://github.com/awakeljw)).
#### Performance Improvement
* Support window functions parallel evaluation. Fixes [#34688](https://github.com/ClickHouse/ClickHouse/issues/34688). [#39631](https://github.com/ClickHouse/ClickHouse/pull/39631) ([Dmitry Novik](https://github.com/novikd)).
* Increase the default value of `max_concurrent_queries` from 100 to 1000. This makes sense when there is a large number of connecting clients, which are slowly sending or receiving data, so the server is not limited by CPU, or when the number of CPU cores is larger than 100. Also, enable the concurrency control by default, and set the desired number of query processing threads in total as twice the number of CPU cores. It improves performance in scenarios with a very large number of concurrent queries. [#46927](https://github.com/ClickHouse/ClickHouse/pull/46927) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fixed filtering by `IN(...)` condition for `Merge` table engine. [#54905](https://github.com/ClickHouse/ClickHouse/pull/54905) ([Nikita Taranov](https://github.com/nickitat)).
* An improvement which takes place when cache is full and there are big reads. [#55158](https://github.com/ClickHouse/ClickHouse/pull/55158) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Add ability to disable checksums for S3 to avoid excessive input file read (this new behavior could be enabled with `s3_disable_checksum=true`). [#55559](https://github.com/ClickHouse/ClickHouse/pull/55559) ([Azat Khuzhin](https://github.com/azat)).
* Now we read synchronously from remote tables when data is in page cache (like we do for local tables). It is faster, doesn't require synchronisation inside thread pool, doesn't hesitate to do `seek`-s on local fs and reduces cpu wait. [#55841](https://github.com/ClickHouse/ClickHouse/pull/55841) ([Nikita Taranov](https://github.com/nickitat)).
* ... This PR follows [#55929](https://github.com/ClickHouse/ClickHouse/issues/55929), it will bring about 30% speedup. - reduce the reserved memory - reduce the `resize` call. [#55957](https://github.com/ClickHouse/ClickHouse/pull/55957) ([lgbo](https://github.com/lgbo-ustc)).
* The performance experiments of **OnTime** on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) show that this change could bring the improvements of **7.4%, 5.9%, 4.7%, 3.0%, and 4.6%** to the QPS of the query Q2, Q3, Q4, Q5 and Q6 respectively while having no impact on others. [#56079](https://github.com/ClickHouse/ClickHouse/pull/56079) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
* Limit the number of threads busy inside the query profiler. If there are more - they will skip profiling. [#56105](https://github.com/ClickHouse/ClickHouse/pull/56105) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* WindowTransform decrease amount of virtual function calls. [#56120](https://github.com/ClickHouse/ClickHouse/pull/56120) ([Maksim Kita](https://github.com/kitaisreal)).
* Allow recursive tuple field pruning in ORC to speed up scaning. [#56122](https://github.com/ClickHouse/ClickHouse/pull/56122) ([李扬](https://github.com/taiyang-li)).
* This pull request provides countRows support for Npy data format. Now with setting `optimize_count_from_files=1` queries like `select count() from file(data.npy)` will work much more fast because of caching the results. [#56304](https://github.com/ClickHouse/ClickHouse/pull/56304) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Queries with aggregation and a large number of streams will use less amount of memory during the plan's construction. [#57074](https://github.com/ClickHouse/ClickHouse/pull/57074) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Improve performance of executing queries for use cases with many users. [#57106](https://github.com/ClickHouse/ClickHouse/pull/57106) ([Andrej Hoos](https://github.com/adikus)).
* Trivial improvement on array join, reuse some intermediate results. [#57183](https://github.com/ClickHouse/ClickHouse/pull/57183) ([李扬](https://github.com/taiyang-li)).
* There are cases when stack unwinding was slow. [#57221](https://github.com/ClickHouse/ClickHouse/pull/57221) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Now we use default read pool for reading from external storage when `max_streams = 1`. It is beneficial when read prefetches are enabled. [#57334](https://github.com/ClickHouse/ClickHouse/pull/57334) ([Nikita Taranov](https://github.com/nickitat)).
#### Improvement
* Engine `Merge` filters the records according to the row policies of the underlying tables. [#50209](https://github.com/ClickHouse/ClickHouse/pull/50209) ([Ilya Golshtein](https://github.com/ilejn)).
* Add a setting `max_execution_time_leaf` to limit the execution time on shard for distributed query, and `timeout_overflow_mode_leaf` to control the behaviour if timeout happens. [#51823](https://github.com/ClickHouse/ClickHouse/pull/51823) ([Duc Canh Le](https://github.com/canhld94)).
* Fix possible postgresql logical replication conversion_error when using MaterializedPostgreSQL. [#53721](https://github.com/ClickHouse/ClickHouse/pull/53721) ([takakawa](https://github.com/takakawa)).
* Set `background_fetches_pool_size` to 16, background_schedule_pool_size to 512 that is better for production usage with frequent small insertions. [#54327](https://github.com/ClickHouse/ClickHouse/pull/54327) ([Denny Crane](https://github.com/den-crane)).
* While read data from a csv format file, and at end of line is'\r' , which not followed by '\n', then we will enconter the exception as below ``` Cannot parse CSV format: found \r (CR) not followed by \n (LF). Line must end by \n (LF) or \r\n (CR LF) or \n\r.: ``` In clickhouse, the csv end of line must be \n or \r\n or \n\r, so the \r must be followed by \n , but in some suitation, the csv input data is abnormal, like above, \r is at end of line. [#54340](https://github.com/ClickHouse/ClickHouse/pull/54340) ([KevinyhZou](https://github.com/KevinyhZou)).
* Update arrow library to release-13.0.0 that supports new encodings. Closes [#44505](https://github.com/ClickHouse/ClickHouse/issues/44505). [#54800](https://github.com/ClickHouse/ClickHouse/pull/54800) ([Kruglov Pavel](https://github.com/Avogar)).
* Improve performance of ON CLUSTER queries by removing heavy system calls to get all network interfaces when looking for local ip address in the DDL entry hosts list. [#54909](https://github.com/ClickHouse/ClickHouse/pull/54909) ([Duc Canh Le](https://github.com/canhld94)).
* Keeper improvement: improve memory-usage during startup by delaying log preprocessing. [#55660](https://github.com/ClickHouse/ClickHouse/pull/55660) ([Antonio Andelic](https://github.com/antonio2368)).
* Fixed accounting of memory allocated before attaching thread to a query or a user. [#56089](https://github.com/ClickHouse/ClickHouse/pull/56089) ([Nikita Taranov](https://github.com/nickitat)).
* ClickHouse keeper reports its running availability zone at `/keeper/availability-zone` path, when running on AWS environment. [#56104](https://github.com/ClickHouse/ClickHouse/pull/56104) ([Jianfei Hu](https://github.com/incfly)).
* Add support for LARGE_LIST with Arrow. [#56118](https://github.com/ClickHouse/ClickHouse/pull/56118) ([edef](https://github.com/edef1c)).
* Improved performance of glob matching for `file` and `hdfs` storages. [#56141](https://github.com/ClickHouse/ClickHouse/pull/56141) ([Andrey Zvonov](https://github.com/zvonand)).
* Allow manual compaction of `EmbeddedRocksDB` via `OPTIMIZE` query. [#56225](https://github.com/ClickHouse/ClickHouse/pull/56225) ([Azat Khuzhin](https://github.com/azat)).
* Posting lists in inverted indexes are now compressed which reduces their size by 10-30%. [#56226](https://github.com/ClickHouse/ClickHouse/pull/56226) ([Harry Lee](https://github.com/HarryLeeIBM)).
* Add ability to specify BlockBasedTableOptions for EmbeddedRocksDB. [#56264](https://github.com/ClickHouse/ClickHouse/pull/56264) ([Azat Khuzhin](https://github.com/azat)).
* `SHOW COLUMNS` now displays MySQL's equivalent data type name when the connection was made through the MySQL protocol. Previously, this was the case when setting `use_mysql_types_in_show_columns = 1`. The setting is retained but made obsolete. [#56277](https://github.com/ClickHouse/ClickHouse/pull/56277) ([Robert Schulze](https://github.com/rschu1ze)).
* Fixed possible `The local set of parts of table doesn't look like the set of parts in ZooKeeper` error if server was restarted just after `TRUNCATE` or `DROP PARTITION`. [#56282](https://github.com/ClickHouse/ClickHouse/pull/56282) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Parallelise `BackupEntriesCollector`. [#56312](https://github.com/ClickHouse/ClickHouse/pull/56312) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fixed handling of non-const query strings in functions `formatQuery()`/ `formatQuerySingleLine()`. Also added `OrNull` variants of both functions that return a NULL when a query cannot be parsed instead of throwing an exception. [#56327](https://github.com/ClickHouse/ClickHouse/pull/56327) ([Robert Schulze](https://github.com/rschu1ze)).
* Support create and materialized index in the same alter query, also support modity TTL and materialize TTL in the same query. Closes [#55651](https://github.com/ClickHouse/ClickHouse/issues/55651). [#56331](https://github.com/ClickHouse/ClickHouse/pull/56331) ([flynn](https://github.com/ucasfl)).
* Enable adding new disk to storage configuration without restart. [#56367](https://github.com/ClickHouse/ClickHouse/pull/56367) ([Duc Canh Le](https://github.com/canhld94)).
* Allow backup of materialized view with dropped inner table instead of failing the backup. [#56387](https://github.com/ClickHouse/ClickHouse/pull/56387) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Queries to `system.replicas` initiate requests to ZooKeeper when certain columns are queried. When there are thousands of tables these requests might produce a considerable load on ZooKeeper. If there are multiple simultaneous queries to `system.replicas` they do same requests multiple times. The change is to "deduplicate" requests from concurrent queries. [#56420](https://github.com/ClickHouse/ClickHouse/pull/56420) ([Alexander Gololobov](https://github.com/davenger)).
* Add transition from reading key to reading quoted key when double quotes are found. [#56423](https://github.com/ClickHouse/ClickHouse/pull/56423) ([Arthur Passos](https://github.com/arthurpassos)).
* Fix transfer query to MySQL compatible query. [#56456](https://github.com/ClickHouse/ClickHouse/pull/56456) ([flynn](https://github.com/ucasfl)).
* Add support for backing up and restoring tables using KeeperMap engine. [#56460](https://github.com/ClickHouse/ClickHouse/pull/56460) ([Antonio Andelic](https://github.com/antonio2368)).
* 404 response for CompleteMultipartUpload has to be rechecked. Operation could be done on server even if client got timeout or other network errors. The next retry of CompleteMultipartUpload receives 404 response. If the object key exists that operation is considered as successful. [#56475](https://github.com/ClickHouse/ClickHouse/pull/56475) ([Sema Checherinda](https://github.com/CheSema)).
* Enable the HTTP OPTIONS method by default - it simplifies requesting ClickHouse from a web browser. [#56483](https://github.com/ClickHouse/ClickHouse/pull/56483) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* The value for `dns_max_consecutive_failures` was changed by mistake in [#46550](https://github.com/ClickHouse/ClickHouse/issues/46550) - this is reverted and adjusted to a better value. Also, increased the HTTP keep-alive timeout to a reasonable value from production. [#56485](https://github.com/ClickHouse/ClickHouse/pull/56485) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Load base backups lazily (a base backup won't be loaded until it's needed). Also add some log message and profile events for backups. [#56516](https://github.com/ClickHouse/ClickHouse/pull/56516) ([Vitaly Baranov](https://github.com/vitlibar)).
* Setting `query_cache_store_results_of_queries_with_nondeterministic_functions` (with values `false` or `true`) was marked obsolete. It was replaced by setting `query_cache_nondeterministic_function_handling`, a three-valued enum that controls how the query cache handles queries with non-deterministic functions: a) throw an exception (default behavior), b) save the non-deterministic query result regardless, or c) ignore, i.e. don't throw an exception and don't cache the result. [#56519](https://github.com/ClickHouse/ClickHouse/pull/56519) ([Robert Schulze](https://github.com/rschu1ze)).
* Rewrite equality with `is null` check in JOIN ON section. *Analyzer only*. [#56538](https://github.com/ClickHouse/ClickHouse/pull/56538) ([vdimir](https://github.com/vdimir)).
* Function`concat` now supports arbitrary argument types (instead of only String and FixedString arguments). This makes it behave more similar to MySQL `concat` implementation. For example, `SELECT concat('ab', 42)` now returns `ab42`. [#56540](https://github.com/ClickHouse/ClickHouse/pull/56540) ([Serge Klochkov](https://github.com/slvrtrn)).
* Allow getting cache configuration from 'named_collection' section in config or from sql created named collection. [#56541](https://github.com/ClickHouse/ClickHouse/pull/56541) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Update `query_masking_rules` when reloading the config ([#56449](https://github.com/ClickHouse/ClickHouse/issues/56449)). [#56573](https://github.com/ClickHouse/ClickHouse/pull/56573) ([Mikhail Koviazin](https://github.com/mkmkme)).
* Make removeoutdatedtables() less aggressive with unsuccessful postgres connection. [#56609](https://github.com/ClickHouse/ClickHouse/pull/56609) ([jsc0218](https://github.com/jsc0218)).
* Currenting setting takes too much time to connnect to PG when URL is not right, so the relevant query stucks there and get cancelled. [#56648](https://github.com/ClickHouse/ClickHouse/pull/56648) ([jsc0218](https://github.com/jsc0218)).
* ClickHouse keeper reports its running availability zone at `/keeper/availability-zone` path. This can be configured via `<availability_zone><value>us-west-1a</value></availability_zone>`. [#56715](https://github.com/ClickHouse/ClickHouse/pull/56715) ([Jianfei Hu](https://github.com/incfly)).
* Do not allow tables on different replicas have different aggregate functions in SimpleAggregateFunction columns. [#56724](https://github.com/ClickHouse/ClickHouse/pull/56724) ([Duc Canh Le](https://github.com/canhld94)).
* Add support for the [well-known Protobuf types](https://protobuf.dev/reference/protobuf/google.protobuf/) in the Protobuf format. [#56741](https://github.com/ClickHouse/ClickHouse/pull/56741) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
* Keeper improvement: disable compressed logs by default in Keeper. [#56763](https://github.com/ClickHouse/ClickHouse/pull/56763) ([Antonio Andelic](https://github.com/antonio2368)).
* Add config setting `wait_dictionaries_load_at_startup`:. [#56782](https://github.com/ClickHouse/ClickHouse/pull/56782) ([Vitaly Baranov](https://github.com/vitlibar)).
* There was a potential vulnerability in previous ClickHouse versions: if a user has connected and unsuccessfully tried to authenticate with the "interserver secret" method, the server didn't terminate the connection immediately but continued to receive and ignore the leftover packets from the client. While these packets are ignored, they are still parsed, and if they use a compression method with another known vulnerability, it will lead to exploitation of it without authentication. This issue was found with [ClickHouse Bug Bounty Program](https://github.com/ClickHouse/ClickHouse/issues/38986) by https://twitter.com/malacupa. [#56794](https://github.com/ClickHouse/ClickHouse/pull/56794) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Fetching a part waits when that part is fully committed on remote replica. It is better not send part in PreActive state. In case of zero copy this is mandatory restriction. [#56808](https://github.com/ClickHouse/ClickHouse/pull/56808) ([Sema Checherinda](https://github.com/CheSema)).
* Implement user-level setting `alter_move_to_space_execute_async` which allow to execute queries `ALTER TABLE ... MOVE PARTITION|PART TO DISK|VOLUME` asynchronously. The size of pool for background executions is controlled by `background_move_pool_size`. Default behavior is synchronous execution. Fixes [#47643](https://github.com/ClickHouse/ClickHouse/issues/47643). [#56809](https://github.com/ClickHouse/ClickHouse/pull/56809) ([alesapin](https://github.com/alesapin)).
* Able to filter by engine when scanning system.tables, avoid unnecessary (potentially time-consuming) connection. [#56813](https://github.com/ClickHouse/ClickHouse/pull/56813) ([jsc0218](https://github.com/jsc0218)).
* Show `total_bytes` and `total_rows` in system tables for RocksDB storage. [#56816](https://github.com/ClickHouse/ClickHouse/pull/56816) ([Aleksandr Musorin](https://github.com/AVMusorin)).
* Allow basic commands in ALTER for TEMPORARY tables. [#56892](https://github.com/ClickHouse/ClickHouse/pull/56892) ([Sergey](https://github.com/icuken)).
* Lz4 compression. Buffer compressed block in a rare case when out buffer capacity is not enough for writing compressed block directly to out's buffer. [#56938](https://github.com/ClickHouse/ClickHouse/pull/56938) ([Sema Checherinda](https://github.com/CheSema)).
* Add metrics for the number of queued jobs, which is useful for the IO thread pool. [#56958](https://github.com/ClickHouse/ClickHouse/pull/56958) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add a setting for PostgreSQL table engine setting in the config file Added a check for the setting Added documentation around the additional setting. [#56959](https://github.com/ClickHouse/ClickHouse/pull/56959) ([Peignon Melvyn](https://github.com/melvynator)).
* Run interpreter with `only_analyze` flag in getsampleblock method. [#56972](https://github.com/ClickHouse/ClickHouse/pull/56972) ([Mikhail Artemenko](https://github.com/Michicosun)).
* Add a new `MergeTree` setting `add_implicit_sign_column_constraint_for_collapsing_engine` (disabled by default). When enabled, it adds an implicit CHECK constraint for `CollapsingMergeTree` tables that restricts the value of the `Sign` column to be only -1 or 1. [#56701](https://github.com/ClickHouse/ClickHouse/issues/56701). [#56986](https://github.com/ClickHouse/ClickHouse/pull/56986) ([Kevin Mingtarja](https://github.com/kevinmingtarja)).
* Function `concat()` can now be called with a single argument, e.g., `SELECT concat('abc')`. This makes its behavior more consistent with MySQL's concat implementation. [#57000](https://github.com/ClickHouse/ClickHouse/pull/57000) ([Serge Klochkov](https://github.com/slvrtrn)).
* Signs all `x-amz-*` headers as required by AWS S3 docs. [#57001](https://github.com/ClickHouse/ClickHouse/pull/57001) ([Arthur Passos](https://github.com/arthurpassos)).
* Function `fromDaysSinceYearZero` (alias: `FROM_DAYS`) can now be used with unsigned and signed integer types (previously, it had to be an unsigned integer). This improve compatibility with 3rd party tools such as Tableau Online. [#57002](https://github.com/ClickHouse/ClickHouse/pull/57002) ([Serge Klochkov](https://github.com/slvrtrn)).
* Add system.s3queue_log to default config. [#57036](https://github.com/ClickHouse/ClickHouse/pull/57036) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Change the default for `wait_dictionaries_load_at_startup` to true, and use this setting only if `dictionaries_lazy_load` is false. [#57133](https://github.com/ClickHouse/ClickHouse/pull/57133) ([Vitaly Baranov](https://github.com/vitlibar)).
* Check dictionary source type on creation even if `dictionaries_lazy_load` is enabled. [#57134](https://github.com/ClickHouse/ClickHouse/pull/57134) ([Vitaly Baranov](https://github.com/vitlibar)).
* Plan-level optimizations can now be enabled/disabled individually. Previously, it was only possible to disable them all. The setting which previously did that (`query_plan_enable_optimizations`) is retained and can still be used to disable all optimizations. [#57152](https://github.com/ClickHouse/ClickHouse/pull/57152) ([Robert Schulze](https://github.com/rschu1ze)).
* The server's exit code will correspond to the exception code. For example, if the server cannot start due to memory limit, it will exit with the code 241 = MEMORY_LIMIT_EXCEEDED. In previous versions, the exit code for exceptions was always 70 = Poco::Util::ExitCode::EXIT_SOFTWARE. [#57153](https://github.com/ClickHouse/ClickHouse/pull/57153) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Do not demangle and symbolize stack frames from __functional c++ header. [#57201](https://github.com/ClickHouse/ClickHouse/pull/57201) ([Mike Kot](https://github.com/myrrc)).
* 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;`. [#57220](https://github.com/ClickHouse/ClickHouse/pull/57220) ([flynn](https://github.com/ucasfl)).
* HTTP server page `/dashboard` now supports charts with multiple lines. [#57236](https://github.com/ClickHouse/ClickHouse/pull/57236) ([Sergei Trifonov](https://github.com/serxa)).
* This pr gives possibility to use suffixes (K, M, G, T, E) along with the amount of memory to be used. Closes [#56879](https://github.com/ClickHouse/ClickHouse/issues/56879). [#57273](https://github.com/ClickHouse/ClickHouse/pull/57273) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
* Bumped Intel QPL (used by codec `DEFLATE_QPL`) from v1.2.0 to v1.3.1 . Also fixed a bug in case of BOF (Block On Fault) = 0, changed to handle page faults by falling back to SW path. [#57291](https://github.com/ClickHouse/ClickHouse/pull/57291) ([jasperzhu](https://github.com/jinjunzh)).
* Make alter materialized view non experimental and deprecate `allow_experimental_alter_materialized_view_structure` setting. Fixes [#15206](https://github.com/ClickHouse/ClickHouse/issues/15206). [#57311](https://github.com/ClickHouse/ClickHouse/pull/57311) ([alesapin](https://github.com/alesapin)).
* Increase default `replicated_deduplication_window` of MergeTree settings from 100 to 1k. [#57335](https://github.com/ClickHouse/ClickHouse/pull/57335) ([sichenzhao](https://github.com/sichenzhao)).
* Stop using `INCONSISTENT_METADATA_FOR_BACKUP` that much. If possible prefer to continue scanning instead of stopping and starting the scanning for backup from the beginning. [#57385](https://github.com/ClickHouse/ClickHouse/pull/57385) ([Vitaly Baranov](https://github.com/vitlibar)).
* Introduce the limit for the maximum number of table projections (default 25). [#57491](https://github.com/ClickHouse/ClickHouse/pull/57491) ([Julia Kartseva](https://github.com/jkartseva)).
* Enable `async_block_ids_cache` by default for `async_inserts` deduplication. [#57513](https://github.com/ClickHouse/ClickHouse/pull/57513) ([alesapin](https://github.com/alesapin)).
#### Build/Testing/Packaging Improvement
* Enable temporary_data_in_cache in s3 tests in CI. [#48425](https://github.com/ClickHouse/ClickHouse/pull/48425) ([vdimir](https://github.com/vdimir)).
* Run sqllogic test. [#56078](https://github.com/ClickHouse/ClickHouse/pull/56078) ([Han Fei](https://github.com/hanfei1991)).
* Add a new build option `SANITIZE_COVERAGE`. If it is enabled, the code is instrumented to track the coverage. The collected information is available inside ClickHouse with: (1) a new function `coverage` that returns an array of unique addresses in the code found after the previous coverage reset; (2) `SYSTEM RESET COVERAGE` query that resets the accumulated data. This allows us to compare the coverage of different tests, including differential code coverage. Continuation of [#20539](https://github.com/ClickHouse/ClickHouse/issues/20539). [#56102](https://github.com/ClickHouse/ClickHouse/pull/56102) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* In [#54043](https://github.com/ClickHouse/ClickHouse/issues/54043) the setup plan started to appear in the logs. It should be only in the `runner_get_all_tests.log` only. As well, send the failed infrastructure event to CI db. [#56214](https://github.com/ClickHouse/ClickHouse/pull/56214) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Some of the stack frames might not be resolved when collecting stacks. In such cases the raw address might be helpful. [#56267](https://github.com/ClickHouse/ClickHouse/pull/56267) ([Alexander Gololobov](https://github.com/davenger)).
* Add an option to disable libssh. [#56333](https://github.com/ClickHouse/ClickHouse/pull/56333) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add automatic check that there are no large translation units. [#56559](https://github.com/ClickHouse/ClickHouse/pull/56559) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Lower the size of the single-binary distribution. This closes [#55181](https://github.com/ClickHouse/ClickHouse/issues/55181). [#56617](https://github.com/ClickHouse/ClickHouse/pull/56617) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Make `clickhouse-local` and `clickhouse-client` available under short names (`ch`, `chl`, `chc`) for usability. [#56634](https://github.com/ClickHouse/ClickHouse/pull/56634) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Information about the sizes of every translation unit and binary file after each build will be sent to the CI database in ClickHouse Cloud. This closes [#56107](https://github.com/ClickHouse/ClickHouse/issues/56107). [#56636](https://github.com/ClickHouse/ClickHouse/pull/56636) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Certain files of "Apache Arrow" library (which we use only for non-essential things like parsing the arrow format) were rebuilt all the time regardless of the build cache. This is fixed. [#56657](https://github.com/ClickHouse/ClickHouse/pull/56657) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Avoid recompiling translation units depending on the autogenerated source file about version. [#56660](https://github.com/ClickHouse/ClickHouse/pull/56660) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Do not fetch changed submodules in the builder container. [#56689](https://github.com/ClickHouse/ClickHouse/pull/56689) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Tracing data of the linker invocations will be sent to the CI database in ClickHouse Cloud. [#56725](https://github.com/ClickHouse/ClickHouse/pull/56725) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Use DWARF 5 debug symbols for the clickhouse binary (was DWARF 4 previously). [#56770](https://github.com/ClickHouse/ClickHouse/pull/56770) ([Michael Kolupaev](https://github.com/al13n321)).
* Optimized build size further by removing unused code from external libraries. [#56786](https://github.com/ClickHouse/ClickHouse/pull/56786) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Set memory usage for client (`1G`) to address problems like this: https://s3.amazonaws.com/clickhouse-test-reports/0/f1bf3f1fc39f520871ec878d815e515e12fd3e7b/fuzzer_astfuzzertsan/report.html. [#56873](https://github.com/ClickHouse/ClickHouse/pull/56873) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* There was an attempt to have the proper listing in [#44311](https://github.com/ClickHouse/ClickHouse/issues/44311), but the fix itself was in the wrong place, so it's still broken. See an [example](https://github.com/ClickHouse/ClickHouse/actions/runs/6897342568/job/18781001022#step:8:25). [#56989](https://github.com/ClickHouse/ClickHouse/pull/56989) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Fixed the memory leak in integration test of postgres dictionary. The case of network partition is not correctly handled at the time of the repo pulled years ago. [#57231](https://github.com/ClickHouse/ClickHouse/pull/57231) ([jsc0218](https://github.com/jsc0218)).
* Fix a test filename typo. [#57272](https://github.com/ClickHouse/ClickHouse/pull/57272) ([jsc0218](https://github.com/jsc0218)).

# Getting Started Guide for Building ClickHouse
The building of ClickHouse is supported on Linux, FreeBSD and macOS.
ClickHouse can be build on Linux, FreeBSD and macOS. If you use Windows, you can still build ClickHouse in a virtual machine running Linux, e.g. [VirtualBox](https://www.virtualbox.org/) with Ubuntu.
If you use Windows, you need to create a virtual machine with Ubuntu. To start working with a virtual machine please install VirtualBox. You can download Ubuntu from the website: https://www.ubuntu.com/#download. Please create a virtual machine from the downloaded image (you should reserve at least 4GB of RAM for it). To run a command-line terminal in Ubuntu, please locate a program containing the word “terminal” in its name (gnome-terminal, konsole etc.) or just press Ctrl+Alt+T.
ClickHouse cannot work or build on a 32-bit system. You should acquire access to a 64-bit system and you can continue reading.
ClickHouse requires a 64-bit system to compile and run, 32-bit systems do not work.
## Creating a Repository on GitHub {#creating-a-repository-on-github}
To start working with ClickHouse repository you will need a GitHub account.
To start developing for ClickHouse you will need a [GitHub](https://www.virtualbox.org/) account. Please also generate a SSH key locally (if you don't have one already) and upload the public key to GitHub as this is a prerequisite for contributing patches.
You probably already have one, but if you do not, please register at https://github.com. In case you do not have SSH keys, you should generate them and then upload them on GitHub. It is required for sending over your patches. It is also possible to use the same SSH keys that you use with any other SSH servers - probably you already have those.
Next, create a fork of the [ClickHouse repository](https://github.com/ClickHouse/ClickHouse/) in your personal account by clicking the "fork" button in the upper right corner.
Create a fork of ClickHouse repository. To do that please click on the “fork” button in the upper right corner at https://github.com/ClickHouse/ClickHouse. It will fork your own copy of ClickHouse/ClickHouse to your account.
To contribute, e.g. a fix for an issue or a feature, please commit your changes to a branch in your fork, then create a "pull request" with the changes to the main repository.
The development process consists of first committing the intended changes into your fork of ClickHouse and then creating a “pull request” for these changes to be accepted into the main repository (ClickHouse/ClickHouse).
For working with Git repositories, please install `git`. In Ubuntu run these commands in a terminal:
To work with Git repositories, please install `git`. To do that in Ubuntu you would run in the command line terminal:
```sh

## Cloning a Repository to Your Development Machine {#cloning-a-repository-to-your-development-machine}
Next, you need to download the source files onto your working machine. This is called “to clone a repository” because it creates a local copy of the repository on your working machine.
First, download the source files to your working machine, i.e. clone the repository:
Run in your terminal:
```sh
git clone git@github.com:your_github_username/ClickHouse.git # replace placeholder with your GitHub user name
cd ClickHouse
```
git clone git@github.com:your_github_username/ClickHouse.git # replace placeholder with your GitHub user name
cd ClickHouse
This command creates a directory `ClickHouse/` containing the source code of ClickHouse. If you specify a custom checkout directory after the URL but it is important that this path does not contain whitespaces as it may lead to problems with the build later on.

:::note
Instructions below assume you are building on Linux. If you are cross-compiling or using building on macOS, please also check for operating system and architecture specific guides, such as building [on macOS for macOS](build-osx.md), [on Linux for macOS](build-cross-osx.md), [on Linux for Linux/RISC-V](build-cross-riscv.md) and so on.

## Build System {#build-system}
ClickHouse uses CMake and Ninja for building.
CMake - a meta-build system that can generate Ninja files (build tasks).
Ninja - a smaller build system with a focus on the speed used to execute those cmake generated tasks.

- `disk` — a disk within a volume.
- `max_data_part_size_bytes` — the maximum size of a part that can be stored on any of the volume’s disks. If the a size of a merged part estimated to be bigger than `max_data_part_size_bytes` then this part will be written to a next volume. Basically this feature allows to keep new/small parts on a hot (SSD) volume and move them to a cold (HDD) volume when they reach large size. Do not use this setting if your policy has only one volume.
- `move_factor` — when the amount of available space gets lower than this factor, data automatically starts to move on the next volume if any (by default, 0.1). ClickHouse sorts existing parts by size from largest to smallest (in descending order) and selects parts with the total size that is sufficient to meet the `move_factor` condition. If the total size of all parts is insufficient, all parts will be moved.
- `prefer_not_to_merge` — Disables merging of data parts on this volume. When this setting is enabled, merging data on this volume is not allowed. This allows controlling how ClickHouse works with slow disks.
- `perform_ttl_move_on_insert` — Disables TTL move on data part INSERT. By default (if enabled) if we insert a data part that already expired by the TTL move rule it immediately goes to a volume/disk declared in move rule. This can significantly slowdown insert in case if destination volume/disk is slow (e.g. S3). If disabled then already expired data part is written into a default volume and then right after moved to TTL volume.
- `load_balancing` - Policy for disk balancing, `round_robin` or `least_used`.
- `least_used_ttl_ms` - Configure timeout (in milliseconds) for the updating available space on all disks (`0` - update always, `-1` - never update, default is `60000`). Note, if the disk can be used by ClickHouse only and is not subject to a online filesystem resize/shrink you can use `-1`, in all other cases it is not recommended, since eventually it will lead to incorrect space distribution.
- `prefer_not_to_merge` — You should not use this setting. Disables merging of data parts on this volume (this is harmful and leads to performance degradation). When this setting is enabled (don't do it), merging data on this volume is not allowed (which is bad). This allows (but you don't need it) controlling (if you want to control something, you're making a mistake) how ClickHouse works with slow disks (but ClickHouse knows better, so please don't use this setting).

ClickHouse comes with a built-in observability dashboard feature which can be accessed by `$HOST:$PORT/dashboard` (requires user and password) that shows the following metrics:
- Queries/second
- CPU usage (cores)
- Queries running
- Merges running
- Selected bytes/second
- IO wait

## async_load_databases {#async_load_databases}
Asynchronous loading of databases and tables.
If `true` all non-system databases with `Ordinary`, `Atomic` and `Replicated` engine will be loaded asynchronously after the ClickHouse server start up. See `system.async_loader` table, `tables_loader_background_pool_size` and `tables_loader_foreground_pool_size` server settings. Any query that tries to access a table, that is not yet loaded, will wait for exactly this table to be started up. If load job fails, query will rethrow an error (instead of shutting down the whole server in case of `async_load_databases = false`). The table that is waited for by at least one query will be loaded with higher priority. DDL queries on a database will wait for exactly that database to be started up.
If `false`, all databases are loaded when the server starts.
The default is `false`.
**Example**
``` xml
<async_load_databases>true</async_load_databases>
```
## tables_loader_foreground_pool_size {#tables_loader_foreground_pool_size}
Sets the number of threads performing load jobs in foreground pool. The foreground pool is used for loading table synchronously before server start listening on a port and for loading tables that are waited for. Foreground pool has higher priority than background pool. It means that no job starts in background pool while there are jobs running in foreground pool.
Possible values:
- Any positive integer.
- Zero. Use all available CPUs.
Default value: 0.
## tables_loader_background_pool_size {#tables_loader_background_pool_size}
Sets the number of threads performing asynchronous load jobs in background pool. The background pool is used for loading tables asynchronously after server start in case there are no queries waiting for the table. It could be beneficial to keep low number of threads in background pool if there are a lot of tables. It will reserve CPU resources for concurrent query execution.
Possible values:
- Any positive integer.
- Zero. Use all available CPUs.

# async_loader
Contains information and status for recent asynchronous jobs (e.g. for tables loading). The table contains a row for every job. There is a tool for visualizing information from this table `utils/async_loader_graph`.
Example:
``` sql
SELECT *
FROM system.async_loader
FORMAT Vertical
LIMIT 1
```
``` text
```
Columns:
- `job` (`String`) - Job name (may be not unique).
- `job_id` (`UInt64`) - Unique ID of the job.
- `dependencies` (`Array(UInt64)`) - List of IDs of jobs that should be done before this job.
- `dependencies_left` (`UInt64`) - Current number of dependencies left to be done.
- `status` (`Enum`) - Current load status of a job:
`PENDING`: Load job is not started yet.
`OK`: Load job executed and was successful.
`FAILED`: Load job executed and failed.
`CANCELED`: Load job is not going to be executed due to removal or dependency failure.
A pending job might be in one of the following states:
- `is_executing` (`UInt8`) - The job is currently being executed by a worker.
- `is_blocked` (`UInt8`) - The job waits for its dependencies to be done.
- `is_ready` (`UInt8`) - The job is ready to be executed and waits for a worker.
- `elapsed` (`Float64`) - Seconds elapsed since start of execution. Zero if job is not started. Total execution time if job finished.
Every job has a pool associated with it and is started in this pool. Each pool has a constant priority and a mutable maximum number of workers. Higher priority (lower `priority` value) jobs are run first. No job with lower priority is started while there is at least one higher priority job ready or executing. Job priority can be elevated (but cannot be lowered) by prioritizing it. For example jobs for a table loading and startup will be prioritized if incoming query required this table. It is possible prioritize a job during its execution, but job is not moved from its `execution_pool` to newly assigned `pool`. The job uses `pool` for creating new jobs to avoid priority inversion. Already started jobs are not preempted by higher priority jobs and always run to completion after start.
- `pool_id` (`UInt64`) - ID of a pool currently assigned to the job.
- `pool` (`String`) - Name of `pool_id` pool.
- `priority` (`Int64`) - Priority of `pool_id` pool.
- `execution_pool_id` (`UInt64`) - ID of a pool the job is executed in. Equals initially assigned pool before execution starts.
- `execution_pool` (`String`) - Name of `execution_pool_id` pool.
- `execution_priority` (`Int64`) - Priority of `execution_pool_id` pool.
- `ready_seqno` (`Nullable(UInt64)`) - Not null for ready jobs. Worker pulls the next job to be executed from a ready queue of its pool. If there are multiple ready jobs, then job with the lowest value of `ready_seqno` is picked.
- `waiters` (`UInt64`) - The number of threads waiting on this job.
- `exception` (`Nullable(String)`) - Not null for failed and canceled jobs. Holds error message raised during query execution or error leading to cancelling of this job along with dependency failure chain of job names.
Time instants during job lifetime:
- `schedule_time` (`DateTime64`) - Time when job was created and scheduled to be executed (usually with all its dependencies).
- `enqueue_time` (`Nullable(DateTime64)`) - Time when job became ready and was enqueued into a ready queue of it's pool. Null if the job is not ready yet.
- `start_time` (`Nullable(DateTime64)`) - Time when worker dequeues the job from ready queue and start its execution. Null if the job is not started yet.
- `finish_time` (`Nullable(DateTime64)`) - Time when job execution is finished. Null if the job is not finished yet.

Calculates the number of different values of the argument up to a specified limit, `N`. If the number of different argument values is greater than `N`, this function returns `N` + 1, otherwise it calculates the exact value.

Recommended for use with small `N`s, up to 10. The maximum value of `N` is 100.

For the state of an aggregate function, this function uses the amount of memory equal to 1 + `N` \* the size of one value of bytes.
When dealing with strings, this function stores a non-cryptographic hash of 8 bytes; the calculation is approximated for strings.
The function also works for several arguments.
For example, if you had a table that logs every search query made by users on your website. Each row in the table represents a single search query, with columns for the user ID, the search query, and the timestamp of the query. You can use `uniqUpTo` to generate a report that shows only the keywords that produced at least 5 unique users.
It works as fast as possible, except for cases when a large N value is used and the number of unique values is slightly less than N.
Usage example:
``` text
Problem: Generate a report that shows only keywords that produced at least 5 unique users.
Solution: Write in the GROUP BY query SearchPhrase HAVING uniqUpTo(4)(UserID) >= 5
```sql
SELECT SearchPhrase
FROM SearchLog
GROUP BY SearchPhrase
HAVING uniqUpTo(4)(UserID) >= 5
```
`uniqUpTo(4)(UserID)` calculates the number of unique `UserID` values for each `SearchPhrase`, but it only counts up to 4 unique values. If there are more than 4 unique `UserID` values for a `SearchPhrase`, the function returns 5 (4 + 1). The `HAVING` clause then filters out the `SearchPhrase` values for which the number of unique `UserID` values is less than 5. This will give you a list of search keywords that were used by at least 5 unique users.

To delete a view, use [DROP VIEW](../../../sql-reference/statements/drop.md#drop-view). Although `DROP TABLE` works for VIEWs as well.
## Live View [Experimental]
## Live View [Deprecated]
:::note
This is an experimental feature that may change in backwards-incompatible ways in the future releases. Enable usage of live views and `WATCH` query using [allow_experimental_live_view](../../../operations/settings/settings.md#allow-experimental-live-view) setting. Input the command `set allow_experimental_live_view = 1`.
:::
This feature is deprecated and will be removed in the future.
```sql
CREATE LIVE VIEW [IF NOT EXISTS] [db.]table_name [WITH REFRESH [value_in_sec]] AS SELECT ...
```
Live views store result of the corresponding [SELECT](../../../sql-reference/statements/select/index.md) query and are updated any time the result of the query changes. Query result as well as partial result needed to combine with new data are stored in memory providing increased performance for repeated queries. Live views can provide push notifications when query result changes using the [WATCH](../../../sql-reference/statements/watch.md) query.
Live views are triggered by insert into the innermost table specified in the query.
Live views work similarly to how a query in a distributed table works. But instead of combining partial results from different servers they combine partial result from current data with partial result from the new data. When a live view query includes a subquery then the cached partial result is only stored for the innermost subquery.
:::info
- [Table function](../../../sql-reference/table-functions/index.md) is not supported as the innermost table.
- Tables that do not have inserts such as a [dictionary](../../../sql-reference/dictionaries/index.md), [system table](../../../operations/system-tables/index.md), a [normal view](#normal), or a [materialized view](#materialized) will not trigger a live view.
- Only queries where one can combine partial result from the old data plus partial result from the new data will work. Live view will not work for queries that require the complete data set to compute the final result or aggregations where the state of the aggregation must be preserved.
- Does not work with replicated or distributed tables where inserts are performed on different nodes.
- Can't be triggered by multiple tables.
See [WITH REFRESH](#live-view-with-refresh) to force periodic updates of a live view that in some cases can be used as a workaround.
:::
### Monitoring Live View Changes
You can monitor changes in the `LIVE VIEW` query result using [WATCH](../../../sql-reference/statements/watch.md) query.
```sql
WATCH [db.]live_view
```
**Example:**
```sql
CREATE TABLE mt (x Int8) Engine = MergeTree ORDER BY x;
CREATE LIVE VIEW lv AS SELECT sum(x) FROM mt;
```
Watch a live view while doing a parallel insert into the source table.
```sql
WATCH lv;
```
```bash
┌─sum(x)─┬─_version─┐
│ 1 │ 1 │
└────────┴──────────┘
┌─sum(x)─┬─_version─┐
│ 3 │ 2 │
└────────┴──────────┘
┌─sum(x)─┬─_version─┐
│ 6 │ 3 │
└────────┴──────────┘
```
```sql
INSERT INTO mt VALUES (1);
INSERT INTO mt VALUES (2);
INSERT INTO mt VALUES (3);
```
Or add [EVENTS](../../../sql-reference/statements/watch.md#events-clause) clause to just get change events.
```sql
WATCH [db.]live_view EVENTS;
```
**Example:**
```sql
WATCH lv EVENTS;
```
```bash
┌─version─┐
│ 1 │
└─────────┘
┌─version─┐
│ 2 │
└─────────┘
┌─version─┐
│ 3 │
└─────────┘
```
You can execute [SELECT](../../../sql-reference/statements/select/index.md) query on a live view in the same way as for any regular view or a table. If the query result is cached it will return the result immediately without running the stored query on the underlying tables.
```sql
SELECT * FROM [db.]live_view WHERE ...
```
### Force Live View Refresh
You can force live view refresh using the `ALTER LIVE VIEW [db.]table_name REFRESH` statement.
### WITH REFRESH Clause
When a live view is created with a `WITH REFRESH` clause then it will be automatically refreshed after the specified number of seconds elapse since the last refresh or trigger.
```sql
CREATE LIVE VIEW [db.]table_name WITH REFRESH [value_in_sec] AS SELECT ...
```
If the refresh value is not specified then the value specified by the [periodic_live_view_refresh](../../../operations/settings/settings.md#periodic-live-view-refresh) setting is used.
**Example:**
```sql
CREATE LIVE VIEW lv WITH REFRESH 5 AS SELECT now();
WATCH lv
```
```bash
┌───────────────now()─┬─_version─┐
│ 2021-02-21 08:47:05 │ 1 │

┌───────────────now()─┬─_version─┐

┌───────────────now()─┬─_version─┐
│ 2021-02-21 08:47:15 │ 3 │

```
```sql
WATCH lv
```
```
Code: 60. DB::Exception: Received from localhost:9000. DB::Exception: Table default.lv does not exist..
```
### Live View Usage
Most common uses of live view tables include:
- Providing push notifications for query result changes to avoid polling.
- Caching results of most frequent queries to provide immediate query results.
- Watching for table changes and triggering a follow-up select queries.
- Watching metrics from system tables using periodic refresh.

- `disk` — диск, находящийся внутри тома.
- `max_data_part_size_bytes` — максимальный размер куска данных, который может находиться на любом из дисков этого тома. Если в результате слияния размер куска ожидается больше, чем max_data_part_size_bytes, то этот кусок будет записан в следующий том. В основном эта функция позволяет хранить новые / мелкие куски на горячем (SSD) томе и перемещать их на холодный (HDD) том, когда они достигают большого размера. Не используйте этот параметр, если политика имеет только один том.
- `move_factor` — доля доступного свободного места на томе, если места становится меньше, то данные начнут перемещение на следующий том, если он есть (по умолчанию 0.1). Для перемещения куски сортируются по размеру от большего к меньшему (по убыванию) и выбираются куски, совокупный размер которых достаточен для соблюдения условия `move_factor`, если совокупный размер всех партов недостаточен, будут перемещены все парты.
- `prefer_not_to_merge` — Отключает слияние кусков данных, хранящихся на данном томе. Если данная настройка включена, то слияние данных, хранящихся на данном томе, не допускается. Это позволяет контролировать работу ClickHouse с медленными дисками.
