### <a id="2210"></a> ClickHouse release 22.10, 2022-10-26
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Rename cache commands: `show caches` -> `show filesystem caches`, `describe cache` -> `describe filesystem cache`. [#41508](https://github.com/ClickHouse/ClickHouse/pull/41508) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Remove support for the `WITH TIMEOUT` section for `LIVE VIEW`. This closes [#40557](https://github.com/ClickHouse/ClickHouse/issues/40557). [#42173](https://github.com/ClickHouse/ClickHouse/pull/42173) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Remove support for the `{database}` macro from the client's prompt. It was displayed incorrectly if the database was unspecified and it was not updated on `USE` statements. This closes [#25891](https://github.com/ClickHouse/ClickHouse/issues/25891). [#42508](https://github.com/ClickHouse/ClickHouse/pull/42508) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
|
||||
#### New Feature
|
||||
* Composable protocol configuration is added. Now different protocols can be set up with different listen hosts. Protocol wrappers such as PROXYv1 can be set up over any other protocols (TCP, TCP secure, MySQL, Postgres). [#41198](https://github.com/ClickHouse/ClickHouse/pull/41198) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Add `S3` as a new type of the destination of backups. Support BACKUP to S3 with as-is path/data structure. [#42333](https://github.com/ClickHouse/ClickHouse/pull/42333) ([Vitaly Baranov](https://github.com/vitlibar)), [#42232](https://github.com/ClickHouse/ClickHouse/pull/42232) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added functions (`randUniform`, `randNormal`, `randLogNormal`, `randExponential`, `randChiSquared`, `randStudentT`, `randFisherF`, `randBernoulli`, `randBinomial`, `randNegativeBinomial`, `randPoisson`) to generate random values according to the specified distributions. This closes [#21834](https://github.com/ClickHouse/ClickHouse/issues/21834). [#42411](https://github.com/ClickHouse/ClickHouse/pull/42411) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* An improvement for ClickHouse Keeper: add support for uploading snapshots to S3. S3 information can be defined inside `keeper_server.s3_snapshot`. [#41342](https://github.com/ClickHouse/ClickHouse/pull/41342) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Added an aggregate function `analysisOfVariance` (`anova`) to perform a statistical test over several groups of normally distributed observations to find out whether all groups have the same mean or not. Original PR [#37872](https://github.com/ClickHouse/ClickHouse/issues/37872). [#42131](https://github.com/ClickHouse/ClickHouse/pull/42131) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Support limiting of temporary data stored on disk using settings `max_temporary_data_on_disk_size_for_user`/`max_temporary_data_on_disk_size_for_query` . [#40893](https://github.com/ClickHouse/ClickHouse/pull/40893) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Add setting `format_json_object_each_row_column_for_object_name` to write/parse object name as column value in JSONObjectEachRow format. [#41703](https://github.com/ClickHouse/ClickHouse/pull/41703) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add BLAKE3 hash-function to SQL. [#33435](https://github.com/ClickHouse/ClickHouse/pull/33435) ([BoloniniD](https://github.com/BoloniniD)).
|
||||
* The function `javaHash` has been extended to integers. [#41131](https://github.com/ClickHouse/ClickHouse/pull/41131) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* Add OpenTelemetry support to ON CLUSTER DDL (require `distributed_ddl_entry_format_version` to be set to 4). [#41484](https://github.com/ClickHouse/ClickHouse/pull/41484) ([Frank Chen](https://github.com/FrankChen021)).
|
||||
* Added system table `asynchronous_insert_log`. It contains information about asynchronous inserts (including results of queries in fire-and-forget mode (with `wait_for_async_insert=0`)) for better introspection. [#42040](https://github.com/ClickHouse/ClickHouse/pull/42040) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Add support for methods `lz4`, `bz2`, `snappy` in HTTP's `Accept-Encoding` which is a non-standard extension to HTTP protocol. [#42071](https://github.com/ClickHouse/ClickHouse/pull/42071) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Adds Morton Coding (ZCurve) encode/decode functions. [#41753](https://github.com/ClickHouse/ClickHouse/pull/41753) ([Constantine Peresypkin](https://github.com/pkit)).
|
||||
* Add support for `SET setting_name = DEFAULT`. [#42187](https://github.com/ClickHouse/ClickHouse/pull/42187) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
|
||||
#### Experimental Feature
|
||||
* Added new infrastructure for query analysis and planning under the `allow_experimental_analyzer` setting. [#31796](https://github.com/ClickHouse/ClickHouse/pull/31796) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Initial implementation of Kusto Query Language. Please don't use it. [#37961](https://github.com/ClickHouse/ClickHouse/pull/37961) ([Yong Wang](https://github.com/kashwy)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Relax the "Too many parts" threshold. This closes [#6551](https://github.com/ClickHouse/ClickHouse/issues/6551). Now ClickHouse will allow more parts in a partition if the average part size is large enough (at least 10 GiB). This allows to have up to petabytes of data in a single partition of a single table on a single server, which is possible using disk shelves or object storage. [#42002](https://github.com/ClickHouse/ClickHouse/pull/42002) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Implement operator precedence element parser to make the required stack size smaller. [#34892](https://github.com/ClickHouse/ClickHouse/pull/34892) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* DISTINCT in order optimization leverage sorting properties of data streams. This improvement will enable reading in order for DISTINCT if applicable (before it was necessary to provide ORDER BY for columns in DISTINCT). [#41014](https://github.com/ClickHouse/ClickHouse/pull/41014) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
* ColumnVector: optimize UInt8 index with AVX512VBMI. [#41247](https://github.com/ClickHouse/ClickHouse/pull/41247) ([Guo Wangyang](https://github.com/guowangy)).
|
||||
* Optimize the lock contentions for `ThreadGroupStatus::mutex`. The performance experiments of **SSB** (Star Schema Benchmark) on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) shows that this change could bring a **2.95x** improvement of the geomean of all subcases' QPS. [#41675](https://github.com/ClickHouse/ClickHouse/pull/41675) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
|
||||
* Add `ldapr` capabilities to AArch64 builds. This is supported from Graviton 2+, Azure and GCP instances. Only appeared in clang-15 [not so long ago](https://github.com/llvm/llvm-project/commit/9609b5daffe9fd28d83d83da895abc5113f76c24). [#41778](https://github.com/ClickHouse/ClickHouse/pull/41778) ([Daniel Kutenin](https://github.com/danlark1)).
|
||||
* Improve performance when comparing strings and one argument is an empty constant string. [#41870](https://github.com/ClickHouse/ClickHouse/pull/41870) ([Jiebin Sun](https://github.com/jiebinn)).
|
||||
* Optimize `insertFrom` of ColumnAggregateFunction to share Aggregate State in some cases. [#41960](https://github.com/ClickHouse/ClickHouse/pull/41960) ([flynn](https://github.com/ucasfl)).
|
||||
* Make writing to `azure_blob_storage` disks faster (respect `max_single_part_upload_size` instead of writing a block per each buffer size). Inefficiency mentioned in [#41754](https://github.com/ClickHouse/ClickHouse/issues/41754). [#42041](https://github.com/ClickHouse/ClickHouse/pull/42041) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Make thread ids in the process list and query_log unique to avoid waste. [#42180](https://github.com/ClickHouse/ClickHouse/pull/42180) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Support skipping cache completely (both download to cache and reading cached data) in case the requested read range exceeds the threshold defined by cache setting `bypass_cache_threashold`, requires to be enabled with `enable_bypass_cache_with_threshold`). [#42418](https://github.com/ClickHouse/ClickHouse/pull/42418) ([Han Shukai](https://github.com/KinderRiven)). This helps on slow local disks.
|
||||
|
||||
#### Improvement
|
||||
* Add setting `allow_implicit_no_password`: in combination with `allow_no_password` it forbids creating a user with no password unless `IDENTIFIED WITH no_password` is explicitly specified. [#41341](https://github.com/ClickHouse/ClickHouse/pull/41341) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Embedded Keeper will always start in the background allowing ClickHouse to start without achieving quorum. [#40991](https://github.com/ClickHouse/ClickHouse/pull/40991) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Made reestablishing a new connection to ZooKeeper more reactive in case of expiration of the previous one. Previously there was a task which spawns every minute by default and thus a table could be in readonly state for about this time. [#41092](https://github.com/ClickHouse/ClickHouse/pull/41092) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Now projections can be used with zero copy replication (zero-copy replication is a non-production feature). [#41147](https://github.com/ClickHouse/ClickHouse/pull/41147) ([alesapin](https://github.com/alesapin)).
|
||||
* Support expression `(EXPLAIN SELECT ...)` in a subquery. Queries like `SELECT * FROM (EXPLAIN PIPELINE SELECT col FROM TABLE ORDER BY col)` became valid. [#40630](https://github.com/ClickHouse/ClickHouse/pull/40630) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Allow changing `async_insert_max_data_size` or `async_insert_busy_timeout_ms` in scope of query. E.g. user wants to insert data rarely and she doesn't have access to the server config to tune default settings. [#40668](https://github.com/ClickHouse/ClickHouse/pull/40668) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Improvements for reading from remote filesystems, made threadpool size for reads/writes configurable. Closes [#41070](https://github.com/ClickHouse/ClickHouse/issues/41070). [#41011](https://github.com/ClickHouse/ClickHouse/pull/41011) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Support all combinators combination in WindowTransform/arratReduce*/initializeAggregation/aggregate functions versioning. Previously combinators like `ForEach/Resample/Map` didn't work in these places, using them led to exception like`State function ... inserts results into non-state column`. [#41107](https://github.com/ClickHouse/ClickHouse/pull/41107) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add function `tryDecrypt` that returns NULL when decrypt fails (e.g. decrypt with incorrect key) instead of throwing an exception. [#41206](https://github.com/ClickHouse/ClickHouse/pull/41206) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Add the `unreserved_space` column to the `system.disks` table to check how much space is not taken by reservations per disk. [#41254](https://github.com/ClickHouse/ClickHouse/pull/41254) ([filimonov](https://github.com/filimonov)).
|
||||
* Support s3 authorization headers in table function arguments. [#41261](https://github.com/ClickHouse/ClickHouse/pull/41261) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Add support for MultiRead in Keeper and internal ZooKeeper client (this is an extension to ZooKeeper protocol, only available in ClickHouse Keeper). [#41410](https://github.com/ClickHouse/ClickHouse/pull/41410) ([Antonio Andelic](https://github.com/antonio2368)).

* Add support for decimal type comparing with floating point literal in IN operator. [#41544](https://github.com/ClickHouse/ClickHouse/pull/41544) ([liang.huang](https://github.com/lhuang09287750)).
|
||||
* Allow readable size values (like `1TB`) in cache config. [#41688](https://github.com/ClickHouse/ClickHouse/pull/41688) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* ClickHouse could cache stale DNS entries for some period of time (15 seconds by default) until the cache won't be updated asynchronously. During these periods ClickHouse can nevertheless try to establish a connection and produce errors. This behavior is fixed. [#41707](https://github.com/ClickHouse/ClickHouse/pull/41707) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Add interactive history search with fzf-like utility (fzf/sk) for `clickhouse-client`/`clickhouse-local` (note you can use `FZF_DEFAULT_OPTS`/`SKIM_DEFAULT_OPTIONS` to additionally configure the behavior). [#41730](https://github.com/ClickHouse/ClickHouse/pull/41730) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Only allow clients connecting to a secure server with an invalid certificate only to proceed with the '--accept-certificate' flag. [#41743](https://github.com/ClickHouse/ClickHouse/pull/41743) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Add function `tryBase58Decode`, similar to the existing function `tryBase64Decode`. [#41824](https://github.com/ClickHouse/ClickHouse/pull/41824) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Improve feedback when replacing partition with different primary key. Fixes [#34798](https://github.com/ClickHouse/ClickHouse/issues/34798). [#41838](https://github.com/ClickHouse/ClickHouse/pull/41838) ([Salvatore](https://github.com/tbsal)).
|
||||
* Fix parallel parsing: segmentator now checks `max_block_size`. This fixed memory overallocation in case of parallel parsing and small LIMIT. [#41852](https://github.com/ClickHouse/ClickHouse/pull/41852) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Don't add "TABLE_IS_DROPPED" exception to `system.errors` if it's happened during SELECT from a system table and was ignored. [#41908](https://github.com/ClickHouse/ClickHouse/pull/41908) ([AlfVII](https://github.com/AlfVII)).
|
||||
* Improve option `enable_extended_results_for_datetime_functions` to return results of type DateTime64 for functions `toStartOfDay`, `toStartOfHour`, `toStartOfFifteenMinutes`, `toStartOfTenMinutes`, `toStartOfFiveMinutes`, `toStartOfMinute` and `timeSlot`. [#41910](https://github.com/ClickHouse/ClickHouse/pull/41910) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* Improve `DateTime` type inference for text formats. Now it respects setting `date_time_input_format` and doesn't try to infer datetimes from numbers as timestamps. Closes [#41389](https://github.com/ClickHouse/ClickHouse/issues/41389) Closes [#42206](https://github.com/ClickHouse/ClickHouse/issues/42206). [#41912](https://github.com/ClickHouse/ClickHouse/pull/41912) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Remove confusing warning when inserting with `perform_ttl_move_on_insert` = false. [#41980](https://github.com/ClickHouse/ClickHouse/pull/41980) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Allow user to write `countState(*)` similar to `count(*)`. This closes [#9338](https://github.com/ClickHouse/ClickHouse/issues/9338). [#41983](https://github.com/ClickHouse/ClickHouse/pull/41983) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Fix `rankCorr` size overflow. [#42020](https://github.com/ClickHouse/ClickHouse/pull/42020) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Added an option to specify an arbitrary string as an environment name in the Sentry's config for more handy reports. [#42037](https://github.com/ClickHouse/ClickHouse/pull/42037) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Fix parsing out-of-range Date from CSV. [#42044](https://github.com/ClickHouse/ClickHouse/pull/42044) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* `parseDataTimeBestEffort` now supports comma between date and time. Closes [#42038](https://github.com/ClickHouse/ClickHouse/issues/42038). [#42049](https://github.com/ClickHouse/ClickHouse/pull/42049) ([flynn](https://github.com/ucasfl)).
|
||||
* Improved stale replica recovery process for `ReplicatedMergeTree`. If a lost replica has some parts which are absent from a healthy replica, but these parts should appear in the future according to the replication queue of the healthy replica, then the lost replica will keep such parts instead of detaching them. [#42134](https://github.com/ClickHouse/ClickHouse/pull/42134) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
* Add a possibility to use `Date32` arguments for date_diff function. Fix issue in date_diff function when using DateTime64 arguments with a start date before Unix epoch and end date after Unix epoch. [#42308](https://github.com/ClickHouse/ClickHouse/pull/42308) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* When uploading big parts to Minio, 'Complete Multipart Upload' can take a long time. Minio sends heartbeats every 10 seconds (see https://github.com/minio/minio/pull/7198). But clickhouse times out earlier, because the default send/receive timeout is [set](https://github.com/ClickHouse/ClickHouse/blob/cc24fcd6d5dfb67f5f66f5483e986bd1010ad9cf/src/IO/S3/PocoHTTPClient.cpp#L123) to 5 seconds. [#42321](https://github.com/ClickHouse/ClickHouse/pull/42321) ([filimonov](https://github.com/filimonov)).
|
||||
* Fix rarely invalid cast of aggregate state types with complex types such as Decimal. This fixes [#42408](https://github.com/ClickHouse/ClickHouse/issues/42408). [#42417](https://github.com/ClickHouse/ClickHouse/pull/42417) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Allow to use `Date32` arguments for `dateName` function. [#42554](https://github.com/ClickHouse/ClickHouse/pull/42554) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* Now filters with NULL literals will be used during index analysis. [#34063](https://github.com/ClickHouse/ClickHouse/issues/34063). [#41842](https://github.com/ClickHouse/ClickHouse/pull/41842) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Merge parts if every part in the range is older than a certain threshold. The threshold can be set by using `min_age_to_force_merge_seconds`. This closes [#35836](https://github.com/ClickHouse/ClickHouse/issues/35836). [#42423](https://github.com/ClickHouse/ClickHouse/pull/42423) ([Antonio Andelic](https://github.com/antonio2368)). This is continuation of [#39550i](https://github.com/ClickHouse/ClickHouse/pull/39550) by [@fastio](https://github.com/fastio) who implemented most of the logic.
|
||||
* Improve the time to recover lost keeper connections. [#42541](https://github.com/ClickHouse/ClickHouse/pull/42541) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|
||||
* Add fuzzer for table definitions [#40096](https://github.com/ClickHouse/ClickHouse/pull/40096) ([Anton Popov](https://github.com/CurtizJ)). This represents the biggest advancement for ClickHouse testing in this year so far.

|
||||
* Aarch64 binaries now require at least ARMv8.2, released in 2016. Most notably, this enables use of ARM LSE, i.e. native atomic operations. Also, CMake build option "NO_ARMV81_OR_HIGHER" has been added to allow compilation of binaries for older ARMv8.0 hardware, e.g. Raspberry Pi 4. [#41610](https://github.com/ClickHouse/ClickHouse/pull/41610) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Allow building ClickHouse with Musl (small changes after it was already supported but broken). [#41987](https://github.com/ClickHouse/ClickHouse/pull/41987) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Add the `$CLICKHOUSE_CRONFILE` file checking to avoid running the `sed` command to get the file not found error on install. [#42081](https://github.com/ClickHouse/ClickHouse/pull/42081) ([Chun-Sheng, Li](https://github.com/peter279k)).
|
||||
* Update cctz to `2022e` to support the new timezone changes. Palestine transitions are now Saturdays at 02:00. Simplify three Ukraine zones into one. Jordan and Syria switch from +02/+03 with DST to year-round +03. (https://data.iana.org/time-zones/tzdb/NEWS). This closes [#42252](https://github.com/ClickHouse/ClickHouse/issues/42252). [#42327](https://github.com/ClickHouse/ClickHouse/pull/42327) ([Alexey Milovidov](https://github.com/alexey-milovidov)). [#42273](https://github.com/ClickHouse/ClickHouse/pull/42273) ([Dom Del Nano](https://github.com/ddelnano)).

||||
* Fixed "Directory already exists and is not empty" error on detaching broken part that might prevent `ReplicatedMergeTree` table from starting replication. Fixes [#40957](https://github.com/ClickHouse/ClickHouse/issues/40957). [#41981](https://github.com/ClickHouse/ClickHouse/pull/41981) ([Alexander Tokmakov](https://github.com/tavplubix)).

|
||||
* `AggregateFunctionQuantile` now correctly works with UInt128 columns. Previously, the quantile state interpreted `UInt128` columns as `Int128` which could have led to incorrect results.

You can build your documentation manually by following the instructions in [docs/tools/README.md](../docs/tools/README.md). Also, our CI runs the documentation build after the `documentation` label is added to PR. You can see the results of a build in the GitHub interface. If you have no permissions to add labels, a reviewer of your PR will add it.

# 2022 Changelog
|
||||
|
||||
### ClickHouse release v22.10.1.1877-stable (98ab5a3c189) FIXME as compared to v22.9.1.2603-stable (3030d4c7ff0)
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Rename cache commands: `show caches` -> `show filesystem caches`, `describe cache` -> `describe filesystem cache`. [#41508](https://github.com/ClickHouse/ClickHouse/pull/41508) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Remove support for the `WITH TIMEOUT` section for `LIVE VIEW`. This closes [#40557](https://github.com/ClickHouse/ClickHouse/issues/40557). [#42173](https://github.com/ClickHouse/ClickHouse/pull/42173) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
|
||||
#### New Feature
|
||||
* Add Rust code support into ClickHouse with BLAKE3 hash-function library as an example. [#33435](https://github.com/ClickHouse/ClickHouse/pull/33435) ([BoloniniD](https://github.com/BoloniniD)).
|
||||
* This is the initial implement of Kusto Query Language. (MVP). [#37961](https://github.com/ClickHouse/ClickHouse/pull/37961) ([Yong Wang](https://github.com/kashwy)).
|
||||
* * Support limiting of temporary data stored on disk using settings `max_temporary_data_on_disk_size_for_user`/`max_temporary_data_on_disk_size_for_query` . [#40893](https://github.com/ClickHouse/ClickHouse/pull/40893) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Support Java integers hashing in `javaHash`. [#41131](https://github.com/ClickHouse/ClickHouse/pull/41131) ([JackyWoo](https://github.com/JackyWoo)).
|
||||
* This PR is to support the OpenSSL in-house build like the BoringSSL submodule. Build flag i.e. ENABLE_CH_BUNDLE_BORINGSSL is used to choose between BoringSSL and OpenSSL. By default, the BoringSSL in-house build will be used. [#41142](https://github.com/ClickHouse/ClickHouse/pull/41142) ([MeenaRenganathan22](https://github.com/MeenaRenganathan22)).

* Composable protocol configuration is added. [#41198](https://github.com/ClickHouse/ClickHouse/pull/41198) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Add OpenTelemetry support to ON CLUSTER DDL(require `distributed_ddl_entry_format_version` to be set to 4). [#41484](https://github.com/ClickHouse/ClickHouse/pull/41484) ([Frank Chen](https://github.com/FrankChen021)).
|
||||
* Add setting `format_json_object_each_row_column_for_object_name` to write/parse object name as column value in JSONObjectEachRow format. [#41703](https://github.com/ClickHouse/ClickHouse/pull/41703) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* adds Morton Coding (ZCurve) encode/decode functions. [#41753](https://github.com/ClickHouse/ClickHouse/pull/41753) ([Constantine Peresypkin](https://github.com/pkit)).
|
||||
* Implement support for different UUID binary formats with support for the two most prevalent ones: the default big-endian and Microsoft's mixed-endian as specified in [RFC 4122](https://datatracker.ietf.org/doc/html/rfc4122#section-4.1.1). [#42108](https://github.com/ClickHouse/ClickHouse/pull/42108) ([ltrk2](https://github.com/ltrk2)).
|
||||
* Added an aggregate function `analysisOfVariance` (`anova`) to perform a statistical test over several groups of normally distributed observations to find out whether all groups have the same mean or not. Original PR [#37872](https://github.com/ClickHouse/ClickHouse/issues/37872). [#42131](https://github.com/ClickHouse/ClickHouse/pull/42131) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Add support for `SET setting_name = DEFAULT`. [#42187](https://github.com/ClickHouse/ClickHouse/pull/42187) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
|
||||
* * Add `URL` Functions which conform rfc. Functions include: `cutToFirstSignificantSubdomainCustomRFC`, `cutToFirstSignificantSubdomainCustomWithWWWRFC`, `cutToFirstSignificantSubdomainRFC`, `cutToFirstSignificantSubdomainWithWWWRFC`, `domainRFC`, `domainWithoutWWWRFC`, `firstSignificantSubdomainCustomRFC`, `firstSignificantSubdomainRFC`, `portRFC`, `topLevelDomainRFC`. [#42274](https://github.com/ClickHouse/ClickHouse/pull/42274) ([Quanfa Fu](https://github.com/dentiscalprum)).
|
||||
* Added functions (`randUniform`, `randNormal`, `randLogNormal`, `randExponential`, `randChiSquared`, `randStudentT`, `randFisherF`, `randBernoulli`, `randBinomial`, `randNegativeBinomial`, `randPoisson` ) to generate random values according to the specified distributions. This closes [#21834](https://github.com/ClickHouse/ClickHouse/issues/21834). [#42411](https://github.com/ClickHouse/ClickHouse/pull/42411) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
|
||||
#### Performance Improvement
|
||||
* Implement operator precedence element parser to resolve stack overflow issues and make the required stack size smaller. [#34892](https://github.com/ClickHouse/ClickHouse/pull/34892) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* DISTINCT in order optimization leverage sorting properties of data streams. This improvement will enable reading in order for DISTINCT if applicable (before it was necessary to provide ORDER BY for columns in DISTINCT). [#41014](https://github.com/ClickHouse/ClickHouse/pull/41014) ([Igor Nikonov](https://github.com/devcrafter)).
|
||||
* ColumnVector: optimize UInt8 index with AVX512VBMI. [#41247](https://github.com/ClickHouse/ClickHouse/pull/41247) ([Guo Wangyang](https://github.com/guowangy)).
|
||||
* The performance experiments of **SSB** (Star Schema Benchmark) on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) shows that this change could bring a **2.95x** improvement of the geomean of all subcases' QPS. [#41675](https://github.com/ClickHouse/ClickHouse/pull/41675) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
|
||||
* Fixed slowness in JSONExtract with LowCardinality(String) tuples. [#41726](https://github.com/ClickHouse/ClickHouse/pull/41726) ([AlfVII](https://github.com/AlfVII)).
|
||||
* Add ldapr capabilities to AArch64 builds. This is supported from Graviton 2+, Azure and GCP instances. Only appeared in clang-15 [not so long ago](https://github.com/llvm/llvm-project/commit/9609b5daffe9fd28d83d83da895abc5113f76c24). [#41778](https://github.com/ClickHouse/ClickHouse/pull/41778) ([Daniel Kutenin](https://github.com/danlark1)).
|
||||
* Improve performance when comparing strings and one argument is empty constant string. [#41870](https://github.com/ClickHouse/ClickHouse/pull/41870) ([Jiebin Sun](https://github.com/jiebinn)).
|
||||
* optimize insertFrom of ColumnAggregateFunction to share Aggregate State in some cases. [#41960](https://github.com/ClickHouse/ClickHouse/pull/41960) ([flynn](https://github.com/ucasfl)).
|
||||
* Relax the "Too many parts" threshold. This closes [#6551](https://github.com/ClickHouse/ClickHouse/issues/6551). Now ClickHouse will allow more parts in a partition if the average part size is large enough (at least 10 GiB). This allows to have up to petabytes of data in a single partition of a single table on a single server, which is possible using disk shelves or object storage. [#42002](https://github.com/ClickHouse/ClickHouse/pull/42002) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Make writing to AzureBlobStorage more efficient (respect `max_single_part_upload_size` instead of writing a block per each buffer size). Inefficiency mentioned in [#41754](https://github.com/ClickHouse/ClickHouse/issues/41754). [#42041](https://github.com/ClickHouse/ClickHouse/pull/42041) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Make thread ids in the process list and query_log unique to avoid waste. [#42180](https://github.com/ClickHouse/ClickHouse/pull/42180) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
|
||||
#### Improvement
|
||||
* Added new infrastructure for query analysis and planning under `allow_experimental_analyzer` setting. [#31796](https://github.com/ClickHouse/ClickHouse/pull/31796) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* * Support expression `(EXPLAIN SELECT ...)` in a subquery. Queries like `SELECT * FROM (EXPLAIN PIPELINE SELECT col FROM TABLE ORDER BY col)` became valid. [#40630](https://github.com/ClickHouse/ClickHouse/pull/40630) ([Vladimir C](https://github.com/vdimir)).
|
||||
* Currently changing `async_insert_max_data_size` or `async_insert_busy_timeout_ms` in scope of query makes no sense and this leads to bad user experience. E.g. user wants to insert data rarely and he doesn't have an access to server config to tune default settings. [#40668](https://github.com/ClickHouse/ClickHouse/pull/40668) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Embedded Keeper will always start in the background allowing ClickHouse to start without achieving quorum. [#40991](https://github.com/ClickHouse/ClickHouse/pull/40991) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Improvements for reading from remote filesystems, made threadpool size for reads/writes configurable. Closes [#41070](https://github.com/ClickHouse/ClickHouse/issues/41070). [#41011](https://github.com/ClickHouse/ClickHouse/pull/41011) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Made reestablishing a new connection more reactive in case of expiration of the previous one. Previously there was a task which spawns every minute by default and thus a table could be in readonly state for about this time. [#41092](https://github.com/ClickHouse/ClickHouse/pull/41092) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Support all combinators combination in WindowTransform/arratReduce*/initializeAggregation/aggregate functions versioning. Previously combinators like `ForEach/Resample/Map` didn't work in these places, using them led to exception like`State function ... inserts results into non-state column`. [#41107](https://github.com/ClickHouse/ClickHouse/pull/41107) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Now projections can be used with zero copy replication. [#41147](https://github.com/ClickHouse/ClickHouse/pull/41147) ([alesapin](https://github.com/alesapin)).
|
||||
* - Add function tryDecrypt that returns NULL when decrypt fail (e.g. decrypt with incorrect key) instead of throwing exception. [#41206](https://github.com/ClickHouse/ClickHouse/pull/41206) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Add the `unreserved_space` column to the `system.disks` table to check how much space is not taken by reservations per disk. [#41254](https://github.com/ClickHouse/ClickHouse/pull/41254) ([filimonov](https://github.com/filimonov)).
|
||||
* Support s3 authorisation headers from ast arguments. [#41261](https://github.com/ClickHouse/ClickHouse/pull/41261) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Add setting 'allow_implicit_no_password' that forbids creating a user with no password unless 'IDENTIFIED WITH no_password' is explicitly specified. [#41341](https://github.com/ClickHouse/ClickHouse/pull/41341) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* keeper-improvement: add support for uploading snapshots to S3. S3 information can be defined inside `keeper_server.s3_snapshot`. [#41342](https://github.com/ClickHouse/ClickHouse/pull/41342) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Add support for MultiRead in Keeper and internal ZooKeeper client. [#41410](https://github.com/ClickHouse/ClickHouse/pull/41410) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* add a support for decimal type comparing with floating point literal in IN operator. [#41544](https://github.com/ClickHouse/ClickHouse/pull/41544) ([liang.huang](https://github.com/lhuang09287750)).
|
||||
* Allow readable size values in cache config. [#41688](https://github.com/ClickHouse/ClickHouse/pull/41688) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Check file path for path traversal attacks in errors logger for input formats. [#41694](https://github.com/ClickHouse/ClickHouse/pull/41694) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* ClickHouse could cache stale DNS entries for some period of time (15 seconds by default) until the cache won't be updated asynchronously. During these period ClickHouse can nevertheless try to establish a connection and produce errors. This behaviour is fixed. [#41707](https://github.com/ClickHouse/ClickHouse/pull/41707) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Add interactive history search with fzf-like utility (fzf/sk) for `clickhouse-client`/`clickhouse-local` (note you can use `FZF_DEFAULT_OPTS`/`SKIM_DEFAULT_OPTIONS` to additionally configure the behavior). [#41730](https://github.com/ClickHouse/ClickHouse/pull/41730) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* For client when connecting to a secure server with invalid certificate only allow to proceed with '--accept-certificate' flag. [#41743](https://github.com/ClickHouse/ClickHouse/pull/41743) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Add function "tryBase58Decode()", similar to the existing function "tryBase64Decode()". [#41824](https://github.com/ClickHouse/ClickHouse/pull/41824) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Improve feedback when replacing partition with different primary key. Fixes [#34798](https://github.com/ClickHouse/ClickHouse/issues/34798). [#41838](https://github.com/ClickHouse/ClickHouse/pull/41838) ([Salvatore](https://github.com/tbsal)).
|
||||
* Replace back `clickhouse su` command with `sudo -u` in start in order to respect limits in `/etc/security/limits.conf`. [#41847](https://github.com/ClickHouse/ClickHouse/pull/41847) ([Eugene Konkov](https://github.com/ekonkov)).
|
||||
* Fix parallel parsing: segmentator now checks max_block_size. [#41852](https://github.com/ClickHouse/ClickHouse/pull/41852) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Don't report TABLE_IS_DROPPED exception in order to skip table in case is was just dropped. [#41908](https://github.com/ClickHouse/ClickHouse/pull/41908) ([AlfVII](https://github.com/AlfVII)).
|
||||
* Improve option enable_extended_results_for_datetime_functions to return results of type DateTime64 for functions toStartOfDay, toStartOfHour, toStartOfFifteenMinutes, toStartOfTenMinutes, toStartOfFiveMinutes, toStartOfMinute and timeSlot. [#41910](https://github.com/ClickHouse/ClickHouse/pull/41910) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* Improve DateTime type inference for text formats. Now it respect setting `date_time_input_format` and doesn't try to infer datetimes from numbers as timestamps. Closes [#41389](https://github.com/ClickHouse/ClickHouse/issues/41389) Closes [#42206](https://github.com/ClickHouse/ClickHouse/issues/42206). [#41912](https://github.com/ClickHouse/ClickHouse/pull/41912) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Remove confusing warning when inserting with `perform_ttl_move_on_insert`=false. [#41980](https://github.com/ClickHouse/ClickHouse/pull/41980) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
* Allow user to write `countState(*)` similar to `count(*)`. This closes [#9338](https://github.com/ClickHouse/ClickHouse/issues/9338). [#41983](https://github.com/ClickHouse/ClickHouse/pull/41983) ([Amos Bird](https://github.com/amosbird)).
|
||||
* - Fix rankCorr size overflow. [#42020](https://github.com/ClickHouse/ClickHouse/pull/42020) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Added an option to specify an arbitrary string as an environment name in the Sentry's config for more handy reports. [#42037](https://github.com/ClickHouse/ClickHouse/pull/42037) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Added system table `asynchronous_insert_log `. It contains information about asynchronous inserts (including results of queries in fire-and-forget mode (with `wait_for_async_insert=0`)) for better introspection. [#42040](https://github.com/ClickHouse/ClickHouse/pull/42040) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Fix parsing out-of-range Date from CSV:. [#42044](https://github.com/ClickHouse/ClickHouse/pull/42044) ([Andrey Zvonov](https://github.com/zvonand)).

|
||||
* Various minor fixes for BLAKE3 function. [#42073](https://github.com/ClickHouse/ClickHouse/pull/42073) ([BoloniniD](https://github.com/BoloniniD)).
|
||||
* Improved stale replica recovery process for `ReplicatedMergeTree`. If lost replica have some parts which absent on a healthy replica, but these parts should appear in future according to replication queue of the healthy replica, then lost replica will keep such parts instead of detaching them. [#42134](https://github.com/ClickHouse/ClickHouse/pull/42134) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
* Support BACKUP to S3 with as-is path/data structure. [#42232](https://github.com/ClickHouse/ClickHouse/pull/42232) ([Azat Khuzhin](https://github.com/azat)).
|
||||

[#42308](https://github.com/ClickHouse/ClickHouse/pull/42308) ([Roman Vasin](https://github.com/rvasin)).
|
||||
* When uploading big parts to minio, 'Complete Multipart Upload' can take a long time. Minio sends heartbeats every 10 seconds (see https://github.com/minio/minio/pull/7198). But clickhouse times out earlier, because the default send/receive timeout is [set](https://github.com/ClickHouse/ClickHouse/blob/cc24fcd6d5dfb67f5f66f5483e986bd1010ad9cf/src/IO/S3/PocoHTTPClient.cpp#L123) to 5 seconds.

|
||||
* Support skipping cache completely (both download to cache and reading cached data) in case the requested read range exceeds the threshold defined by cache setting `bypass_cache_threashold`, requires to be enabled with `enable_bypass_cache_with_threshold`). [#42418](https://github.com/ClickHouse/ClickHouse/pull/42418) ([Han Shukai](https://github.com/KinderRiven)).
|
||||
* Merge parts if every part in the range is older than a certain threshold. The threshold can be set by using `min_age_to_force_merge_seconds`. This closes [#35836](https://github.com/ClickHouse/ClickHouse/issues/35836). [#42423](https://github.com/ClickHouse/ClickHouse/pull/42423) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Enabled CompiledExpressionCache in clickhouse-local. [#42477](https://github.com/ClickHouse/ClickHouse/pull/42477) ([AlfVII](https://github.com/AlfVII)).
|
||||
* Remove support for the `{database}` macro from the client's prompt. It was displayed incorrectly if the database was unspecified and it was not updated on `USE` statements. This closes [#25891](https://github.com/ClickHouse/ClickHouse/issues/25891). [#42508](https://github.com/ClickHouse/ClickHouse/pull/42508) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* - Improve the time to recover lost keeper connections. [#42541](https://github.com/ClickHouse/ClickHouse/pull/42541) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Allow to use Date32 arguments for dateName function. [#42554](https://github.com/ClickHouse/ClickHouse/pull/42554) ([Roman Vasin](https://github.com/rvasin)).
|
||||
|
||||
#### Bug Fix
|
||||
* Now filters with NULL literals will be used during index analysis. This closes https://github.com/ClickHouse/ClickHouse/pull/41814 [#34063](https://github.com/ClickHouse/ClickHouse/issues/34063). [#41842](https://github.com/ClickHouse/ClickHouse/pull/41842) ([Amos Bird](https://github.com/amosbird)).
|
||||
* - Choose correct aggregation method for LowCardinality with BigInt. [#42342](https://github.com/ClickHouse/ClickHouse/pull/42342) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* Fix using subqueries in row policy filters. This PR fixes [#32463](https://github.com/ClickHouse/ClickHouse/issues/32463). [#42562](https://github.com/ClickHouse/ClickHouse/pull/42562) ([Vitaly Baranov](https://github.com/vitlibar)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|
||||
* Added support of WHERE clause generation to AST Fuzzer and possibility to add or remove ORDER BY and WHERE clause. [#38519](https://github.com/ClickHouse/ClickHouse/pull/38519) ([Ilya Yatsishin](https://github.com/qoega)).
|
||||
* Aarch64 binaries now require at least ARMv8.2, released in 2016. Most notably, this enables use of ARM LSE, i.e. native atomic operations. Also, CMake build option "NO_ARMV81_OR_HIGHER" has been added to allow compilation of binaries for older ARMv8.0 hardware, e.g. Raspberry Pi 4. [#41610](https://github.com/ClickHouse/ClickHouse/pull/41610) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* After updating runners to 22.04 cgroups stopped to work in privileged mode, here's the issue https://github.com/moby/moby/issues/42275#issuecomment-1115055846. [#41857](https://github.com/ClickHouse/ClickHouse/pull/41857) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
|
||||
* Allow building ClickHouse with Musl (small changes after it was already supported but broken). [#41987](https://github.com/ClickHouse/ClickHouse/pull/41987) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* - Add the `$CLICKHOUSE_CRONFILE` file checking to avoid running the `sed` command to get the file not found error. [#42081](https://github.com/ClickHouse/ClickHouse/pull/42081) ([Chun-Sheng, Li](https://github.com/peter279k)).
|
||||
* Update cctz to the latest master, update tzdb to 2020e. [#42273](https://github.com/ClickHouse/ClickHouse/pull/42273) ([Dom Del Nano](https://github.com/ddelnano)).
|
||||
* Update tzdata to 2022e to support the new timezone changes. Palestine transitions are now Saturdays at 02:00. Simplify three Ukraine zones into one. Jordan and Syria switch from +02/+03 with DST to year-round +03. (https://data.iana.org/time-zones/tzdb/NEWS). This closes [#42252](https://github.com/ClickHouse/ClickHouse/issues/42252). [#42327](https://github.com/ClickHouse/ClickHouse/pull/42327) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Fix power8 support. [#42462](https://github.com/ClickHouse/ClickHouse/pull/42462) ([Boris Kuschel](https://github.com/bkuschel)).

|
||||
* Mutations were not cancelled properly on server shutdown or `SYSTEM STOP MERGES` query and cancellation might take long time, it's fixed. [#41699](https://github.com/ClickHouse/ClickHouse/pull/41699) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
* Fix wrong result of queries with `ORDER BY` or `GROUP BY` by columns from prefix of sorting key, wrapped into monotonic functions, with enable "read in order" optimization (settings `optimize_read_in_order` and `optimize_aggregation_in_order`). [#41701](https://github.com/ClickHouse/ClickHouse/pull/41701) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Fix possible crash in `SELECT` from `Merge` table with enabled `optimize_monotonous_functions_in_order_by` setting. Fixes [#41269](https://github.com/ClickHouse/ClickHouse/issues/41269). [#41740](https://github.com/ClickHouse/ClickHouse/pull/41740) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Fixed "Part ... intersects part ..." error that might happen in extremely rare cases if replica was restarted just after detaching some part as broken. [#41741](https://github.com/ClickHouse/ClickHouse/pull/41741) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
* Don't allow to create or alter merge tree tables with virtual column name _row_exists, which is reserved for lightweight delete. Fixed [#41716](https://github.com/ClickHouse/ClickHouse/issues/41716). [#41763](https://github.com/ClickHouse/ClickHouse/pull/41763) ([Jianmei Zhang](https://github.com/zhangjmruc)).

## Background
|
||||
|
||||
While [replication](../engines/table-engines/mergetree-family/replication.md) provides protection from hardware failures, it does not protect against human errors: accidental deletion of data, deletion of the wrong table or a table on the wrong cluster, and software bugs that result in incorrect data processing or data corruption. In many cases mistakes like these will affect all replicas. ClickHouse has built-in safeguards to prevent some types of mistakes — for example, by default [you can’t just drop tables with a MergeTree-like engine containing more than 50 Gb of data](server-configuration-parameters/settings.md#max-table-size-to-drop). However, these safeguards do not cover all possible cases and can be circumvented.

Keep in mind that if you backed something up and never tried to restore it, chances are that restore will not work properly when you actually need it (or at least it will take longer than business can tolerate). So whatever backup approach you choose, make sure to automate the restore process as well, and practice it on a spare ClickHouse cluster regularly.

## Backup to S3
|
||||
## Configuring BACKUP/RESTORE to use an S3 Endpoint
|
||||
|
||||
It is possible to `BACKUP`/`RESTORE` to S3, but this disk should be configured
|
||||
in a proper way, since by default you will need to backup metadata from local
|
||||
disk to make backup full.
|
||||
To write backups to an S3 bucket you need three pieces of information:
|
||||
- S3 endpoint,
|
||||
for example `https://mars-doc-test.s3.amazonaws.com/backup-S3/`
|
||||
- Access key ID,
|
||||
for example `ABC123`
|
||||
- Secret access key,
|
||||
for example `Abc+123`
|
||||
|
||||
First of all, you need to configure S3 disk in a special way:
|
||||
:::note
|
||||
Creating an S3 bucket is covered in [Use S3 Object Storage as a ClickHouse disk](/docs/en/integrations/data-ingestion/s3/configuring-s3-for-clickhouse-use.md), just come back to this doc after saving the policy, there is no need to configure ClickHouse to use the S3 bucket.
|
||||
:::
|
||||
|
||||
The destination for a backup will be specified like this:
|
||||
```
|
||||
S3('<S3 endpoint>/<directory>', '<Access key ID>', '<Secret access key>)
|
||||
```
|
||||
|
||||
```sql
|
||||
CREATE TABLE data
|
||||
(
|
||||
`key` Int,
|
||||
`value` String,
|
||||
`array` Array(String)
|
||||
)
|
||||
ENGINE = MergeTree
|
||||
ORDER BY tuple()
|
||||
```
|
||||
|
||||
```sql
|
||||
INSERT INTO data SELECT *
|
||||
FROM generateRandom('key Int, value String, array Array(String)')
|
||||
LIMIT 1000
|
||||
```
|
||||
|
||||
### Create a base (initial) backup
|
||||
|
||||
Incremental backups require a _base_ backup to start from, this example will be used
|
||||
later as the base backup. The first parameter of the S3 destination is the S3 endpoint followed by the directory within the bucket to use for this backup. In this example the directory is named `my_backup`.
|
||||
|
||||
```sql
|
||||
BACKUP TABLE data TO S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_backup', 'ABC123', 'Abc+123')
|
||||
```
|
||||
|
||||
```response
|
||||
┌─id───────────────────────────────────┬─status─────────┐
|
||||
│ de442b75-a66c-4a3c-a193-f76f278c70f3 │ BACKUP_CREATED │
|
||||
└──────────────────────────────────────┴────────────────┘
|
||||
```
|
||||
|
||||
### Add more data
|
||||
|
||||
Incremental backups are populated with the difference between the base backup and the current content of the table being backed up. Add more data before taking the incremental backup:
|
||||
|
||||
```sql
|
||||
INSERT INTO data SELECT *
|
||||
FROM generateRandom('key Int, value String, array Array(String)')
|
||||
LIMIT 100
|
||||
```
|
||||
### Take an incremental backup
|
||||
|
||||
This backup command is similar to the base backup, but adds `SETTINGS base_backup` and the location of the base backup. Note that the destination for the incremental backup is not the same directory as the base, it is the same endpoint with a different target directory within the bucket. The base backup is in `my_backup`, and the incremental will be written to `my_incremental`:
|
||||
```sql
|
||||
BACKUP TABLE data TO S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_incremental', 'ABC123', 'Abc+123') SETTINGS base_backup = S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_backup', 'ABC123', 'Abc+123')
|
||||
```
|
||||
|
||||
```response
|
||||
┌─id───────────────────────────────────┬─status─────────┐
|
||||
│ f6cd3900-850f-41c9-94f1-0c4df33ea528 │ BACKUP_CREATED │
|
||||
└──────────────────────────────────────┴────────────────┘
|
||||
```
|
||||
### Restore from the incremental backup
|
||||
|
||||
This command restores the incremental backup into a new table, `data3`. Note that when an incremental backup is restored, the base backup is also included. Specify only the incremental backup when restoring:
|
||||
```sql
|
||||
RESTORE TABLE data AS data3 FROM S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_incremental', 'ABC123', 'Abc+123')
|
||||
```
|
||||
|
||||
```response
|
||||
┌─id───────────────────────────────────┬─status───┐
|
||||
│ ff0c8c39-7dff-4324-a241-000796de11ca │ RESTORED │
|
||||
└──────────────────────────────────────┴──────────┘
|
||||
```
|
||||
|
||||
### Verify the count
|
||||
|
||||
There were two inserts into the original table `data`, one with 1,000 rows and one with 100 rows, for a total of 1,100. Verify that the restored table has 1,100 rows:
|
||||
```sql
|
||||
SELECT count()
|
||||
FROM data3
|
||||
```
|
||||
```response
|
||||
┌─count()─┐
|
||||
│ 1100 │
|
||||
└─────────┘
|
||||
```
|
||||
|
||||
### Verify the content
|
||||
This compares the content of the original table, `data` with the restored table `data3`:
|
||||
```sql
|
||||
SELECT throwIf((
|
||||
SELECT groupArray(tuple(*))
|
||||
FROM data
|
||||
) != (
|
||||
SELECT groupArray(tuple(*))
|
||||
FROM data3
|
||||
), 'Data does not match after BACKUP/RESTORE')
|
||||
```
|
||||
## BACKUP/RESTORE Using an S3 Disk
|
||||
|
||||
It is also possible to `BACKUP`/`RESTORE` to S3 by configuring an S3 disk in the ClickHouse storage configuration. Configure the disk like this by adding a file to `/etc/clickhouse-server/config.d`:
|
||||
|
||||

При использовании обычного IN-а, запрос отправляется на удалённые серверы, и на каждом из них выполняются подзапросы в секциях `IN` / `JOIN`.
|

|

При использовании `GLOBAL IN` / `GLOBAL JOIN-а`, сначала выполняются все подзапросы для `GLOBAL IN` / `GLOBAL JOIN-ов`, и результаты складываются во временные таблицы. Затем эти временные таблицы передаются на каждый удалённый сервер, и на них выполняются запросы, с использованием этих переданных временных данных.
