### ClickHouse release v21.7, 2021-07-09
|
||||
|
||||
#### Backward Incompatible Change
|
||||
|
||||
* Improved performance of queries with explicitly defined large sets. Added compatibility setting `legacy_column_name_of_tuple_literal`. It makes sense to set it to `true`, while doing rolling update of cluster from version lower than 21.7 to any higher version. Otherwise distributed queries with explicitly defined sets at `IN` clause may fail during update. [#25371](https://github.com/ClickHouse/ClickHouse/pull/25371) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Forward/backward incompatible change of maximum buffer size in clickhouse-keeper (an experimental alternative to ZooKeeper). Better to do it now (before production), than later. [#25421](https://github.com/ClickHouse/ClickHouse/pull/25421) ([alesapin](https://github.com/alesapin)).
|
||||
|
||||
#### New Feature
|
||||
|
||||
* Support configuration in YAML format as alternative to XML. This closes [#3607](https://github.com/ClickHouse/ClickHouse/issues/3607). [#21858](https://github.com/ClickHouse/ClickHouse/pull/21858) ([BoloniniD](https://github.com/BoloniniD)).
|
||||
* Provides a way to restore replicated table when the data is (possibly) present, but the ZooKeeper metadata is lost. Resolves [#13458](https://github.com/ClickHouse/ClickHouse/issues/13458). [#13652](https://github.com/ClickHouse/ClickHouse/pull/13652) ([Mike Kot](https://github.com/myrrc)).
|
||||
* Support structs and maps in Arrow/Parquet/ORC and dictionaries in Arrow input/output formats. Present new setting `output_format_arrow_low_cardinality_as_dictionary`. [#24341](https://github.com/ClickHouse/ClickHouse/pull/24341) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Added support for `Array` type in dictionaries. [#25119](https://github.com/ClickHouse/ClickHouse/pull/25119) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Added function `bitPositionsToArray`. Closes [#23792](https://github.com/ClickHouse/ClickHouse/issues/23792). Author [Kevin Wan] (@MaxWk). [#25394](https://github.com/ClickHouse/ClickHouse/pull/25394) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Added function `dateName` to return names like 'Friday' or 'April'. Author [Daniil Kondratyev] (@dankondr). [#25372](https://github.com/ClickHouse/ClickHouse/pull/25372) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Add `toJSONString` function to serialize columns to their JSON representations. [#25164](https://github.com/ClickHouse/ClickHouse/pull/25164) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Now `query_log` has two new columns: `initial_query_start_time`, `initial_query_start_time_microsecond` that record the starting time of a distributed query if any. [#25022](https://github.com/ClickHouse/ClickHouse/pull/25022) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Add aggregate function `segmentLengthSum`. [#24250](https://github.com/ClickHouse/ClickHouse/pull/24250) ([flynn](https://github.com/ucasfl)).
|
||||
* Add a new boolean setting `prefer_global_in_and_join` which defaults all IN/JOIN as GLOBAL IN/JOIN. [#23434](https://github.com/ClickHouse/ClickHouse/pull/23434) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Support `ALTER DELETE` queries for `Join` table engine. [#23260](https://github.com/ClickHouse/ClickHouse/pull/23260) ([foolchi](https://github.com/foolchi)).
|
||||
* Add `quantileBFloat16` aggregate function as well as the corresponding `quantilesBFloat16` and `medianBFloat16`. It is very simple and fast quantile estimator with relative error not more than 0.390625%. This closes [#16641](https://github.com/ClickHouse/ClickHouse/issues/16641). [#23204](https://github.com/ClickHouse/ClickHouse/pull/23204) ([Ivan Novitskiy](https://github.com/RedClusive)).
|
||||
* Implement `sequenceNextNode()` function useful for `flow analysis`. [#19766](https://github.com/ClickHouse/ClickHouse/pull/19766) ([achimbab](https://github.com/achimbab)).
|
||||
|
||||
#### Experimental Feature
|
||||
|
||||
* Add support for virtual filesystem over HDFS. [#11058](https://github.com/ClickHouse/ClickHouse/pull/11058) ([overshov](https://github.com/overshov)) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Now clickhouse-keeper (an experimental alternative to ZooKeeper) supports ZooKeeper-like `digest` ACLs. [#24448](https://github.com/ClickHouse/ClickHouse/pull/24448) ([alesapin](https://github.com/alesapin)).
|
||||
|
||||
#### Performance Improvement
|
||||
|
||||
* Added optimization that transforms some functions to reading of subcolumns to reduce amount of read data. E.g., statement `col IS NULL` is transformed to reading of subcolumn `col.null`. Optimization can be enabled by setting `optimize_functions_to_subcolumns` which is currently off by default. [#24406](https://github.com/ClickHouse/ClickHouse/pull/24406) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Rewrite more columns to possible alias expressions. This may enable better optimization, such as projections. [#24405](https://github.com/ClickHouse/ClickHouse/pull/24405) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Index of type `bloom_filter` can be used for expressions with `hasAny` function with constant arrays. This closes: [#24291](https://github.com/ClickHouse/ClickHouse/issues/24291). [#24900](https://github.com/ClickHouse/ClickHouse/pull/24900) ([Vasily Nemkov](https://github.com/Enmk)).
|
||||
* Add exponential backoff to reschedule read attempt in case RabbitMQ queues are empty. (ClickHouse has support for importing data from RabbitMQ). Closes [#24340](https://github.com/ClickHouse/ClickHouse/issues/24340). [#24415](https://github.com/ClickHouse/ClickHouse/pull/24415) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
|
||||
#### Improvement
|
||||
|
||||
* Allow to limit bandwidth for replication. Add two Replicated\*MergeTree settings: `max_replicated_fetches_network_bandwidth` and `max_replicated_sends_network_bandwidth` which allows to limit maximum speed of replicated fetches/sends for table. Add two server-wide settings (in `default` user profile): `max_replicated_fetches_network_bandwidth_for_server` and `max_replicated_sends_network_bandwidth_for_server` which limit maximum speed of replication for all tables. The settings are not followed perfectly accurately. Turned off by default. Fixes [#1821](https://github.com/ClickHouse/ClickHouse/issues/1821). [#24573](https://github.com/ClickHouse/ClickHouse/pull/24573) ([alesapin](https://github.com/alesapin)).
|
||||
* Resource constraints and isolation for ODBC and Library bridges. Use separate `clickhouse-bridge` group and user for bridge processes. Set oom_score_adj so the bridges will be first subjects for OOM killer. Set set maximum RSS to 1 GiB. Closes [#23861](https://github.com/ClickHouse/ClickHouse/issues/23861). [#25280](https://github.com/ClickHouse/ClickHouse/pull/25280) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Add standalone `clickhouse-keeper` symlink to the main `clickhouse` binary. Now it's possible to run coordination without the main clickhouse server. [#24059](https://github.com/ClickHouse/ClickHouse/pull/24059) ([alesapin](https://github.com/alesapin)).
|
||||
* Use global settings for query to `VIEW`. Fixed the behavior when queries to `VIEW` use local settings, that leads to errors if setting on `CREATE VIEW` and `SELECT` were different. As for now, `VIEW` won't use these modified settings, but you can still pass additional settings in `SETTINGS` section of `CREATE VIEW` query. Close [#20551](https://github.com/ClickHouse/ClickHouse/issues/20551). [#24095](https://github.com/ClickHouse/ClickHouse/pull/24095) ([Vladimir](https://github.com/vdimir)).
|
||||
* On server start, parts with incorrect partition ID would not be ever removed, but always detached. [#25070](https://github.com/ClickHouse/ClickHouse/issues/25070). [#25166](https://github.com/ClickHouse/ClickHouse/pull/25166) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||||
* Increase size of background schedule pool to 128 (`background_schedule_pool_size` setting). It allows avoiding replication queue hung on slow zookeeper connection. [#25072](https://github.com/ClickHouse/ClickHouse/pull/25072) ([alesapin](https://github.com/alesapin)).
|
||||
* Add merge tree setting `max_parts_to_merge_at_once` which limits the number of parts that can be merged in the background at once. Doesn't affect `OPTIMIZE FINAL` query. Fixes [#1820](https://github.com/ClickHouse/ClickHouse/issues/1820). [#24496](https://github.com/ClickHouse/ClickHouse/pull/24496) ([alesapin](https://github.com/alesapin)).
|
||||
* Allow `NOT IN` operator to be used in partition pruning. [#24894](https://github.com/ClickHouse/ClickHouse/pull/24894) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Recognize IPv4 addresses like `127.0.1.1` as local. This is controversial and closes [#23504](https://github.com/ClickHouse/ClickHouse/issues/23504). Michael Filimonov will test this feature. [#24316](https://github.com/ClickHouse/ClickHouse/pull/24316) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* ClickHouse database created with MaterializeMySQL (it is an experimental feature) now contains all column comments from the MySQL database that materialized. [#25199](https://github.com/ClickHouse/ClickHouse/pull/25199) ([Storozhuk Kostiantyn](https://github.com/sand6255)).
|
||||
* Add settings (`connection_auto_close`/`connection_max_tries`/`connection_pool_size`) for MySQL storage engine. [#24146](https://github.com/ClickHouse/ClickHouse/pull/24146) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Improve startup time of Distributed engine. [#25663](https://github.com/ClickHouse/ClickHouse/pull/25663) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Improvement for Distributed tables. Drop replicas from dirname for internal_replication=true (allows INSERT into Distributed with cluster from any number of replicas, before only 15 replicas was supported, everything more will fail with ENAMETOOLONG while creating directory for async blocks). [#25513](https://github.com/ClickHouse/ClickHouse/pull/25513) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Added support `Interval` type for `LowCardinality`. It is needed for intermediate values of some expressions. Closes [#21730](https://github.com/ClickHouse/ClickHouse/issues/21730). [#25410](https://github.com/ClickHouse/ClickHouse/pull/25410) ([Vladimir](https://github.com/vdimir)).
|
||||
* Add `==` operator on time conditions for `sequenceMatch` and `sequenceCount` functions. For eg: sequenceMatch('(?1)(?t==1)(?2)')(time, data = 1, data = 2). [#25299](https://github.com/ClickHouse/ClickHouse/pull/25299) ([Christophe Kalenzaga](https://github.com/mga-chka)).
|
||||
* Add settings `http_max_fields`, `http_max_field_name_size`, `http_max_field_value_size`. [#25296](https://github.com/ClickHouse/ClickHouse/pull/25296) ([Ivan](https://github.com/abyss7)).
|
||||
* Add support for function `if` with `Decimal` and `Int` types on its branches. This closes [#20549](https://github.com/ClickHouse/ClickHouse/issues/20549). This closes [#10142](https://github.com/ClickHouse/ClickHouse/issues/10142). [#25283](https://github.com/ClickHouse/ClickHouse/pull/25283) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Update prompt in `clickhouse-client` and display a message when reconnecting. This closes [#10577](https://github.com/ClickHouse/ClickHouse/issues/10577). [#25281](https://github.com/ClickHouse/ClickHouse/pull/25281) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Correct memory tracking in aggregate function `topK`. This closes [#25259](https://github.com/ClickHouse/ClickHouse/issues/25259). [#25260](https://github.com/ClickHouse/ClickHouse/pull/25260) ([alexey-milovidov](https://github.com/alexey-milovidov)).
|
||||
* Fix `topLevelDomain` for IDN hosts (i.e. `example.рф`), before it returns empty string for such hosts. [#25103](https://github.com/ClickHouse/ClickHouse/pull/25103) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Detect Linux kernel version at runtime (for worked nested epoll, that is required for `async_socket_for_remote`/`use_hedged_requests`, otherwise remote queries may stuck). [#25067](https://github.com/ClickHouse/ClickHouse/pull/25067) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* For distributed query, when `optimize_skip_unused_shards=1`, allow to skip shard with condition like `(sharding key) IN (one-element-tuple)`. (Tuples with many elements were supported. Tuple with single element did not work because it is parsed as literal). [#24930](https://github.com/ClickHouse/ClickHouse/pull/24930) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Improved log messages of S3 errors, no more double whitespaces in case of empty keys and buckets. [#24897](https://github.com/ClickHouse/ClickHouse/pull/24897) ([Vladimir Chebotarev](https://github.com/excitoon)).
|
||||
* Some queries require multi-pass semantic analysis. Try reusing built sets for `IN` in this case. [#24874](https://github.com/ClickHouse/ClickHouse/pull/24874) ([Amos Bird](https://github.com/amosbird)).
|
||||
* Respect `max_distributed_connections` for `insert_distributed_sync` (otherwise for huge clusters and sync insert it may run out of `max_thread_pool_size`). [#24754](https://github.com/ClickHouse/ClickHouse/pull/24754) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Avoid hiding errors like `Limit for rows or bytes to read exceeded` for scalar subqueries. [#24545](https://github.com/ClickHouse/ClickHouse/pull/24545) ([nvartolomei](https://github.com/nvartolomei)).
|
||||
* Make String-to-Int parser stricter so that `toInt64('+')` will throw. [#24475](https://github.com/ClickHouse/ClickHouse/pull/24475) ([Amos Bird](https://github.com/amosbird)).
|
||||
* If `SSD_CACHE` is created with DDL query, it can be created only inside `user_files` directory. [#24466](https://github.com/ClickHouse/ClickHouse/pull/24466) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* PostgreSQL support for specifying non default schema for insert queries. Closes [#24149](https://github.com/ClickHouse/ClickHouse/issues/24149). [#24413](https://github.com/ClickHouse/ClickHouse/pull/24413) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Fix IPv6 addresses resolving (i.e. fixes `select * from remote('[::1]', system.one)`). [#24319](https://github.com/ClickHouse/ClickHouse/pull/24319) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fix trailing whitespaces in FROM clause with subqueries in multiline mode, and also changes the output of the queries slightly in a more human friendly way. [#24151](https://github.com/ClickHouse/ClickHouse/pull/24151) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Improvement for Distributed tables. Add ability to split distributed batch on failures (i.e. due to memory limits, corruptions), under `distributed_directory_monitor_split_batch_on_failure` (OFF by default). [#23864](https://github.com/ClickHouse/ClickHouse/pull/23864) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Handle column name clashes for `Join` table engine. Closes [#20309](https://github.com/ClickHouse/ClickHouse/issues/20309). [#23769](https://github.com/ClickHouse/ClickHouse/pull/23769) ([Vladimir](https://github.com/vdimir)).
|
||||
* Display progress for `File` table engine in `clickhouse-local` and on INSERT query in `clickhouse-client` when data is passed to stdin. Closes [#18209](https://github.com/ClickHouse/ClickHouse/issues/18209). [#23656](https://github.com/ClickHouse/ClickHouse/pull/23656) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Bugfixes and improvements of `clickhouse-copier`. Allow to copy tables with different (but compatible schemas). Closes [#9159](https://github.com/ClickHouse/ClickHouse/issues/9159). Added test to copy ReplacingMergeTree. Closes [#22711](https://github.com/ClickHouse/ClickHouse/issues/22711). Support TTL on columns and Data Skipping Indices. It simply removes it to create internal Distributed table (underlying table will have TTL and skipping indices). Closes [#19384](https://github.com/ClickHouse/ClickHouse/issues/19384). Allow to copy MATERIALIZED and ALIAS columns. There are some cases in which it could be helpful (e.g. if this column is in PRIMARY KEY). Now it could be allowed by setting `allow_to_copy_alias_and_materialized_columns` property to true in task configuration. Closes [#9177](https://github.com/ClickHouse/ClickHouse/issues/9177). Closes [#11007] (https://github.com/ClickHouse/ClickHouse/issues/11007). Closes [#9514](https://github.com/ClickHouse/ClickHouse/issues/9514). Added a property `allow_to_drop_target_partitions` in task configuration to drop partition in original table before moving helping tables. Closes [#20957](https://github.com/ClickHouse/ClickHouse/issues/20957). Get rid of `OPTIMIZE DEDUPLICATE` query. This hack was needed, because `ALTER TABLE MOVE PARTITION` was retried many times and plain MergeTree tables don't have deduplication. Closes [#17966](https://github.com/ClickHouse/ClickHouse/issues/17966). Write progress to ZooKeeper node on path `task_path + /status` in JSON format. Closes [#20955](https://github.com/ClickHouse/ClickHouse/issues/20955). Support for ReplicatedTables without arguments. Closes [#24834](https://github.com/ClickHouse/ClickHouse/issues/24834) .[#23518](https://github.com/ClickHouse/ClickHouse/pull/23518) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Added sleep with backoff between read retries from S3. [#23461](https://github.com/ClickHouse/ClickHouse/pull/23461) ([Vladimir Chebotarev](https://github.com/excitoon)).
|
||||
* Respect `insert_allow_materialized_columns` (allows materialized columns) for INSERT into `Distributed` table. [#23349](https://github.com/ClickHouse/ClickHouse/pull/23349) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Add ability to push down LIMIT for distributed queries. [#23027](https://github.com/ClickHouse/ClickHouse/pull/23027) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Fix zero-copy replication with several S3 volumes (Fixes [#22679](https://github.com/ClickHouse/ClickHouse/issues/22679)). [#22864](https://github.com/ClickHouse/ClickHouse/pull/22864) ([ianton-ru](https://github.com/ianton-ru)).
|
||||
* Resolve the actual port number bound when a user requests any available port from the operating system to show it in the log message. [#25569](https://github.com/ClickHouse/ClickHouse/pull/25569) ([bnaecker](https://github.com/bnaecker)).
|
||||
* Fixed case, when sometimes conversion of postgres arrays resulted in String data type, not n-dimensional array, because `attndims` works incorrectly in some cases. Closes [#24804](https://github.com/ClickHouse/ClickHouse/issues/24804). [#25538](https://github.com/ClickHouse/ClickHouse/pull/25538) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Fix convertion of DateTime with timezone for MySQL, PostgreSQL, ODBC. Closes [#5057](https://github.com/ClickHouse/ClickHouse/issues/5057). [#25528](https://github.com/ClickHouse/ClickHouse/pull/25528) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Distinguish KILL MUTATION for different tables (fixes unexpected `Cancelled mutating parts` error). [#25025](https://github.com/ClickHouse/ClickHouse/pull/25025) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Allow to declare S3 disk at root of bucket (S3 virtual filesystem is an experimental feature under development). [#24898](https://github.com/ClickHouse/ClickHouse/pull/24898) ([Vladimir Chebotarev](https://github.com/excitoon)).
|
||||
* Enable reading of subcolumns (e.g. components of Tuples) for distributed tables. [#24472](https://github.com/ClickHouse/ClickHouse/pull/24472) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* A feature for MySQL compatibility protocol: make `user` function to return correct output. Closes [#25697](https://github.com/ClickHouse/ClickHouse/pull/25697). [#25697](https://github.com/ClickHouse/ClickHouse/pull/25697) ([sundyli](https://github.com/sundy-li)).
|
||||
|
||||
#### Bug Fix
|
||||
|
||||
* Improvement for backward compatibility. Use old modulo function version when used in partition key. Closes [#23508](https://github.com/ClickHouse/ClickHouse/issues/23508). [#24157](https://github.com/ClickHouse/ClickHouse/pull/24157) ([Kseniia Sumarokova](https://github.com/kssenii)).

## Faster builds for development

Normally all tools of the ClickHouse bundle, such as `clickhouse-server`, `clickhouse-client` etc., are linked into a single static executable, `clickhouse`. This executable must be re-linked on every change, which might be slow. Two common ways to improve linking time are to use `lld` linker, and use the 'split' build configuration, which builds a separate binary for every tool, and further splits the code into several shared libraries. To enable these tweaks, pass the following flags to `cmake`:

### ReplicatedMergeTree in Atomic Database {#replicatedmergetree-in-atomic-database}
|
||||
|
||||
For [ReplicatedMergeTree](../table-engines/mergetree-family/replication.md#table_engines-replication) tables, it is recommended to not specify engine parameters - path in ZooKeeper and replica name. In this case, configuration parameters will be used [default_replica_path](../../operations/server-configuration-parameters/settings.md#default_replica_path) and [default_replica_name](../../operations/server-configuration-parameters/settings.md#default_replica_name). If you want to specify engine parameters explicitly, it is recommended to use {uuid} macros. This is useful so that unique paths are automatically generated for each table in ZooKeeper.

# [experimental] Replicated {#replicated}
|
||||
|
||||
The engine is based on the [Atomic](../../engines/database-engines/atomic.md) engine. It supports replication of metadata via DDL log being written to ZooKeeper and executed on all of the replicas for a given database.
|
||||
|
||||
One ClickHouse server can have multiple replicated databases running and updating at the same time. But there can't be multiple replicas of the same replicated database.
|
||||
|
||||
## Creating a Database {#creating-a-database}
|
||||
``` sql
|
||||
CREATE DATABASE testdb ENGINE = Replicated('zoo_path', 'shard_name', 'replica_name') [SETTINGS ...]
|
||||
```
|
||||
|
||||
**Engine Parameters**
|
||||
|
||||
- `zoo_path` — ZooKeeper path. The same ZooKeeper path corresponds to the same database.
|
||||
- `shard_name` — Shard name. Database replicas are grouped into shards by `shard_name`.
|
||||
- `replica_name` — Replica name. Replica names must be different for all replicas of the same shard.
|
||||
|
||||
!!! note "Warning"
|
||||
For [ReplicatedMergeTree](../table-engines/mergetree-family/replication.md#table_engines-replication) tables if no arguments provided, then default arguments are used: `/clickhouse/tables/{uuid}/{shard}` and `{replica}`. These can be changed in the server settings [default_replica_path](../../operations/server-configuration-parameters/settings.md#default_replica_path) and [default_replica_name](../../operations/server-configuration-parameters/settings.md#default_replica_name). Macro `{uuid}` is unfolded to table's uuid, `{shard}` and `{replica}` are unfolded to values from server config, not from database engine arguments. But in the future, it will be possible to use `shard_name` and `replica_name` of Replicated database.
|
||||
|
||||
## Specifics and Recommendations {#specifics-and-recommendations}
|
||||
|
||||
DDL queries with `Replicated` database work in a similar way to [ON CLUSTER](../../sql-reference/distributed-ddl.md) queries, but with minor differences.
|
||||
|
||||
First, the DDL request tries to execute on the initiator (the host that originally received the request from the user). If the request is not fulfilled, then the user immediately receives an error, other hosts do not try to fulfill it. If the request has been successfully completed on the initiator, then all other hosts will automatically retry until they complete it. The initiator will try to wait for the query to be completed on other hosts (no longer than [distributed_ddl_task_timeout](../../operations/settings/settings.md#distributed_ddl_task_timeout)) and will return a table with the query execution statuses on each host.
|
||||
|
||||
The behavior in case of errors is regulated by the [distributed_ddl_output_mode](../../operations/settings/settings.md#distributed_ddl_output_mode) setting, for a `Replicated` database it is better to set it to `null_status_on_timeout` — i.e. if some hosts did not have time to execute the request for [distributed_ddl_task_timeout](../../operations/settings/settings.md#distributed_ddl_task_timeout), then do not throw an exception, but show the `NULL` status for them in the table.
|
||||
|
||||
The [system.clusters](../../operations/system-tables/clusters.md) system table contains a cluster named like the replicated database, which consists of all replicas of the database. This cluster is updated automatically when creating/deleting replicas, and it can be used for [Distributed](../../engines/table-engines/special/distributed.md#distributed) tables.
|
||||
|
||||
When creating a new replica of the database, this replica creates tables by itself. If the replica has been unavailable for a long time and has lagged behind the replication log — it checks its local metadata with the current metadata in ZooKeeper, moves the extra tables with data to a separate non-replicated database (so as not to accidentally delete anything superfluous), creates the missing tables, updates the table names if they have been renamed. The data is replicated at the `ReplicatedMergeTree` level, i.e. if the table is not replicated, the data will not be replicated (the database is responsible only for metadata).
|
||||
|
||||
## Usage Example {#usage-example}
|
||||
|
||||
Creating a cluster with three hosts:
|
||||
|
||||
``` sql
|
||||
node1 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','shard1','replica1');
|
||||
node2 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','shard1','other_replica');
|
||||
node3 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','other_shard','{replica}');
|
||||
```
|
||||
|
||||
Running the DDL-query:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE r.rmt (n UInt64) ENGINE=ReplicatedMergeTree ORDER BY n;
|
||||
```
|
||||
|
||||
``` text
|
||||
┌─────hosts────────────┬──status─┬─error─┬─num_hosts_remaining─┬─num_hosts_active─┐
|
||||
│ shard1|replica1 │ 0 │ │ 2 │ 0 │
|
||||
│ shard1|other_replica │ 0 │ │ 1 │ 0 │
|
||||
│ other_shard|r1 │ 0 │ │ 0 │ 0 │
|
||||
└──────────────────────┴─────────┴───────┴─────────────────────┴──────────────────┘
|
||||
```
|
||||
|
||||
Showing the system table:
|
||||
|
||||
``` sql
|
||||
SELECT cluster, shard_num, replica_num, host_name, host_address, port, is_local
|
||||
FROM system.clusters WHERE cluster='r';
|
||||
```
|
||||
|
||||
``` text
|
||||
┌─cluster─┬─shard_num─┬─replica_num─┬─host_name─┬─host_address─┬─port─┬─is_local─┐
|
||||
│ r │ 1 │ 1 │ node3 │ 127.0.0.1 │ 9002 │ 0 │
|
||||
│ r │ 2 │ 1 │ node2 │ 127.0.0.1 │ 9001 │ 0 │
|
||||
│ r │ 2 │ 2 │ node1 │ 127.0.0.1 │ 9000 │ 1 │
|
||||
└─────────┴───────────┴─────────────┴───────────┴──────────────┴──────┴──────────┘
|
||||
```
|
||||
|
||||
Creating a distributed table and inserting the data:
|
||||
|
||||
``` sql
|
||||
node2 :) CREATE TABLE r.d (n UInt64) ENGINE=Distributed('r','r','rmt', n % 2);
|
||||
node3 :) INSERT INTO r SELECT * FROM numbers(10);
|
||||
node1 :) SELECT materialize(hostName()) AS host, groupArray(n) FROM r.d GROUP BY host;
|
||||
```
|
||||
|
||||
``` text
|
||||
┌─hosts─┬─groupArray(n)─┐
|
||||
│ node1 │ [1,3,5,7,9] │
|
||||
│ node2 │ [0,2,4,6,8] │
|
||||
└───────┴───────────────┘
|
||||
```
|
||||
|
||||
Adding replica on the one more host:
|
||||
|
||||
``` sql
|
||||
node4 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','other_shard','r2');
|
||||
```
|
||||
|
||||
The cluster configuration will look like this:
|
||||
|
||||
``` text
|
||||
┌─cluster─┬─shard_num─┬─replica_num─┬─host_name─┬─host_address─┬─port─┬─is_local─┐
|
||||
│ r │ 1 │ 1 │ node3 │ 127.0.0.1 │ 9002 │ 0 │
|
||||
│ r │ 1 │ 2 │ node4 │ 127.0.0.1 │ 9003 │ 0 │
|
||||
│ r │ 2 │ 1 │ node2 │ 127.0.0.1 │ 9001 │ 0 │
|
||||
│ r │ 2 │ 2 │ node1 │ 127.0.0.1 │ 9000 │ 1 │
|
||||
└─────────┴───────────┴─────────────┴───────────┴──────────────┴──────┴──────────┘
|
||||
```
|
||||
|
||||
The distributed table also will get data from the new host:
|
||||
|
||||
```sql
|
||||
node2 :) SELECT materialize(hostName()) AS host, groupArray(n) FROM r.d GROUP BY host;
|
||||
```
|
||||
|
||||
```text
|
||||
┌─hosts─┬─groupArray(n)─┐
|
||||
│ node2 │ [1,3,5,7,9] │
|
||||
│ node4 │ [0,2,4,6,8] │

||||
└───────┴───────────────┘

# [pre-production] clickhouse-keeper
|
||||
|
||||
ClickHouse server use [ZooKeeper](https://zookeeper.apache.org/) coordination system for data [replication](../engines/table-engines/mergetree-family/replication.md) and [distributed DDL](../sql-reference/distributed-ddl.md) queries execution. ClickHouse Keeper is an alternative coordination system compatible with ZooKeeper.
|
||||
|
||||
!!! warning "Warning"
|
||||
This feature currently in pre-production stage. We test it in our CI and on small internal installations.
|
||||
|
||||
## Implementation details
|
||||
|
||||
ZooKeeper is one of the first well-known open-source coordination systems. It's implemented in Java, has quite a simple and powerful data model. ZooKeeper's coordination algorithm called ZAB (ZooKeeper Atomic Broadcast) doesn't provide linearizability guarantees for reads, because each ZooKeeper node serves reads locally. Unlike ZooKeeper `clickhouse-keeper` written in C++ and use [RAFT algorithm](https://raft.github.io/) [implementation](https://github.com/eBay/NuRaft). This algorithm allows to have linearizability for reads and writes, has several open-source implementations in different languages.
|
||||
|
||||
By default, `clickhouse-keeper` provides the same guarantees as ZooKeeper (linearizable writes, non-linearizable reads). It has a compatible client-server protocol, so any standard ZooKeeper client can be used to interact with `clickhouse-keeper`. Snapshots and logs have an incompatible format with ZooKeeper, but `clickhouse-keeper-converter` tool allows to convert ZooKeeper data to `clickhouse-keeper` snapshot. Interserver protocol in `clickhouse-keeper` also incompatible with ZooKeeper so mixed ZooKeeper/clickhouse-keeper cluster is impossible.
|
||||
|
||||
## Configuration
|
||||
|
||||
`clickhouse-keeper` can be used as a standalone replacement for ZooKeeper or as an internal part of the `clickhouse-server`, but in both cases configuration is almost the same `.xml` file. The main `clickhouse-keeper` configuration tag is `<keeper_server>`. Keeper configuration has the following parameters:

||||

|
||||
- `heart_beat_interval_ms` — how often a clickhouse-keeper leader will send heartbeats to followers
|
||||
- `election_timeout_lower_bound_ms` — if follower didn't receive heartbeats from the leader in this interval, then it can initiate leader election
|
||||
- `election_timeout_upper_bound_ms` — if follower didn't receive heartbeats from the leader in this interval, then it must initiate leader election
|
||||
- `rotate_log_storage_interval` — how many logs to store in a single file
|
||||
- `reserved_log_items` — how many coordination logs to store before compaction
|
||||
- `snapshot_distance` — how often clickhouse-keeper will create new snapshots (in the number of logs)
|
||||
- `snapshots_to_keep` — how many snapshots to keep
|
||||
- `stale_log_gap` — the threshold when leader consider follower as stale and send snapshot to it instead of logs
|
||||
- `force_sync` — call `fsync` on each write to coordination log
|
||||
- `raft_logs_level` — text logging level about coordination (trace, debug, and so on)
|
||||
- `shutdown_timeout` — wait to finish internal connections and shutdown
|
||||
- `startup_timeout` — if the server doesn't connect to other quorum participants in the specified timeout it will terminate
|
||||
|
||||
Quorum configuration is located in `<keeper_server>.<raft_configuration>` section and contain servers description. The only parameter for the whole quorum is `secure`, which enables encrypted connection for communication between quorum participants. The main parameters for each `<server>` are:
|
||||
|
||||
- `id` — server_id in quorum
|
||||
- `hostname` — hostname where this server placed
|
||||
- `port` — port where this server listen for connections
|
||||
|
||||

## How to run
|
||||
|
||||
`clickhouse-keeper` is bundled into `clickhouse-server` package, just add configuration of `<keeper_server>` and start clickhouse-server as always. If you want to run standalone `clickhouse-keeper` you can start it in a similar way with:
|
||||
|
||||
```bash
|
||||
clickhouse-keeper --config /etc/your_path_to_config/config.xml --daemon
|
||||
```

## [experimental] Migration from ZooKeeper
|
||||
|
||||
Seamlessly migration from ZooKeeper to `clickhouse-keeper` is impossible you have to stop your ZooKeeper cluster, convert data and start `clickhouse-keeper`. `clickhouse-keeper-converter` tool allows to convert ZooKeeper logs and snapshots to `clickhouse-keeper` snapshot. It works only with ZooKeeper > 3.4. Steps for migration:
|
||||
|
||||
1. Stop all ZooKeeper nodes.
|
||||
|
||||
2. [optional, but recommended] Found ZooKeeper leader node, start and stop it again. It will force ZooKeeper to create consistent snapshot.
|
||||
|
||||
3. Run `clickhouse-keeper-converter` on leader, example
|
||||
|
||||
```bash
|
||||
clickhouse-keeper-converter --zookeeper-logs-dir /var/lib/zookeeper/version-2 --zookeeper-snapshots-dir /var/lib/zookeeper/version-2 --output-dir /path/to/clickhouse/keeper/snapshots
|
||||
```
|
||||
|
||||
4. Copy snapshot to `clickhouse-server` nodes with configured `keeper` or start `clickhouse-keeper` instead of ZooKeeper. Snapshot must persist only on leader node, leader will sync it automatically to other nodes.

The config can also define “substitutions”. If an element has the `incl` attribute, the corresponding substitution from the file will be used as the value. By default, the path to the file with substitutions is `/etc/metrika.xml`. This can be changed in the [include_from](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-include_from) element in the server config. The substitution values are specified in `/yandex/substitution_name` elements in this file. If a substitution specified in `incl` does not exist, it is recorded in the log. To prevent ClickHouse from logging missing substitutions, specify the `optional="true"` attribute (for example, settings for [macros](../operations/server-configuration-parameters/settings.md)).
|
||||
|
||||
If you want to replace an entire element with a substitution use `include` as element name.
|
||||
|
||||
XML substitution example:
|
||||
|
||||
```xml
|
||||
<yandex>
|
||||
<!-- Appends XML subtree found at `/profiles-in-zookeeper` ZK path to `<profiles>` element. -->
|
||||
<profiles from_zk="/profiles-in-zookeeper" />
|
||||
|
||||
<users>
|
||||
<!-- Replaces `include` element with the subtree found at `/users-in-zookeeper` ZK path. -->
|
||||
<include from_zk="/users-in-zookeeper" />
|
||||
<include from_zk="/other-users-in-zookeeper" />
|
||||
</users>
|
||||
</yandex>
|
||||
```
|
||||
|
||||
Substitutions can also be performed from ZooKeeper. To do this, specify the attribute `from_zk = "/path/to/node"`. The element value is replaced with the contents of the node at `/path/to/node` in ZooKeeper. You can also put an entire XML subtree on the ZooKeeper node and it will be fully inserted into the source element.

## Implicit Type Conversion {#implicit-type-conversion}
|
||||
|
||||
`INNER JOIN`, `LEFT JOIN`, `RIGHT JOIN`, and `FULL JOIN` queries support the implicit type conversion for "join keys". However the query can not be executed, if join keys from the left and the right tables cannot be converted to a single type (for example, there is no data type that can hold all values from both `UInt64` and `Int64`, or `String` and `Int32`).
|
||||
|
||||
**Example**
|
||||
|
||||
Consider the table `t_1`:

## Сборка ClickHouse {#build-clickhouse}
|
||||
|
||||
Чтобы запустить сборку в компиляторе Xcode's native AppleClang:
|
||||
|
||||
``` bash
|
||||
$ cd ClickHouse
|
||||
$ rm -rf build
|
||||
$ mkdir build
|
||||
$ cd build
|
||||
$ cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_JEMALLOC=OFF ..
|
||||
$ cmake --build . --config RelWithDebInfo
|
||||
$ cd ..
|
||||
```
|
||||
|
||||
Чтобы запустить сборку в компиляторе Homebrew's vanilla Clang:
|
||||
|
||||
``` bash
|
||||
$ cd ClickHouse
|
||||
$ rm -rf build
|
||||
$ mkdir build
|
||||
$ cd build
|
||||
$ cmake -DCMAKE_C_COMPILER=$(brew --prefix llvm)/bin/clang -DCMAKE_CXX_COMPILER==$(brew --prefix llvm)/bin/clang++ -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_JEMALLOC=OFF ..
|
||||
$ cmake -DCMAKE_C_COMPILER=$(brew --prefix llvm)/bin/clang -DCMAKE_CXX_COMPILER=$(brew --prefix llvm)/bin/clang++ -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_JEMALLOC=OFF ..
|
||||
$ cmake --build . --config RelWithDebInfo
|
||||
$ cd ..
|
||||
```
|
||||
|
||||
Чтобы собрать с помощью компилятора Homebrew's vanilla GCC:
|
||||
|
||||
``` bash
|
||||
$ cd ClickHouse
|
||||
$ rm -rf build
|
||||
$ mkdir build
|
||||
$ cd build
|
||||
$ cmake -DCMAKE_C_COMPILER=$(brew --prefix gcc)/bin/gcc-10 -DCMAKE_CXX_COMPILER=$(brew --prefix gcc)/bin/g++-10 -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_JEMALLOC=OFF ..
|
||||
$ cmake --build . --config RelWithDebInfo
|
||||
$ cd ..
|
||||
```
|
||||
|
||||
## Предупреждения {#caveats}
|
||||
|
||||
Если будете запускать `clickhouse-server`, убедитесь, что увеличили системную переменную `maxfiles`.
|
||||
|
||||
!!! info "Note"
|
||||
Вам понадобится команда `sudo`.
|
||||
|
||||
1. Создайте файл `/Library/LaunchDaemons/limit.maxfiles.plist` и поместите в него следующее:
|
||||
|
||||
``` xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
|
||||

|
||||
<false/>
|
||||
</dict>
|
||||
</plist>
|
||||
```
|
||||
|
||||
2. Выполните команду:
|
||||
|
||||
``` bash
|

# [экспериментальный] Replicated {#replicated}
|
||||
|
||||
Движок основан на движке [Atomic](../../engines/database-engines/atomic.md). Он поддерживает репликацию метаданных через журнал DDL, записываемый в ZooKeeper и выполняемый на всех репликах для данной базы данных.
|
||||
|
||||
На одном сервере ClickHouse может одновременно работать и обновляться несколько реплицированных баз данных. Но не может существовать нескольких реплик одной и той же реплицированной базы данных.
|
||||
|
||||
## Создание базы данных {#creating-a-database}
|
||||
``` sql
|
||||
CREATE DATABASE testdb ENGINE = Replicated('zoo_path', 'shard_name', 'replica_name') [SETTINGS ...]
|
||||
```
|
||||
|
||||
**Параметры движка**
|
||||
|
||||
- `zoo_path` — путь в ZooKeeper. Один и тот же путь ZooKeeper соответствует одной и той же базе данных.
|
||||
- `shard_name` — Имя шарда. Реплики базы данных группируются в шарды по имени.
|
||||
- `replica_name` — Имя реплики. Имена реплик должны быть разными для всех реплик одного и того же шарда.
|
||||
|
||||
!!! note "Предупреждение"
|
||||
Для таблиц [ReplicatedMergeTree](../table-engines/mergetree-family/replication.md#table_engines-replication) если аргументы не заданы, то используются аргументы по умолчанию: `/clickhouse/tables/{uuid}/{shard}` и `{replica}`. Они могут быть изменены в серверных настройках: [default_replica_path](../../operations/server-configuration-parameters/settings.md#default_replica_path) и [default_replica_name](../../operations/server-configuration-parameters/settings.md#default_replica_name). Макрос `{uuid}` раскрывается в `UUID` таблицы, `{shard}` и `{replica}` — в значения из конфига сервера. В будущем появится возможность использовать значения `shard_name` и `replica_name` аргументов движка базы данных `Replicated`.
|
||||
|
||||
## Особенности и рекомендации {#specifics-and-recommendations}
|
||||
|
||||
DDL-запросы с базой данных `Replicated` работают похожим образом на [ON CLUSTER](../../sql-reference/distributed-ddl.md) запросы, но с небольшими отличиями.
|
||||
|
||||
Сначала DDL-запрос пытается выполниться на инициаторе (том хосте, который изначально получил запрос от пользователя). Если запрос не выполнился, то пользователь сразу получает ошибку, другие хосты не пытаются его выполнить. Если запрос успешно выполнился на инициаторе, то все остальные хосты будут автоматически делать попытки выполнить его.
|
||||
Инициатор попытается дождаться выполнения запроса на других хостах (не дольше [distributed_ddl_task_timeout](../../operations/settings/settings.md#distributed_ddl_task_timeout)) и вернёт таблицу со статусами выполнения запроса на каждом хосте.
|
||||
|
||||
Поведение в случае ошибок регулируется настройкой [distributed_ddl_output_mode](../../operations/settings/settings.md#distributed_ddl_output_mode), для `Replicated` лучше выставлять её в `null_status_on_timeout` — т.е. если какие-то хосты не успели выполнить запрос за [distributed_ddl_task_timeout](../../operations/settings/settings.md#distributed_ddl_task_timeout), то вместо исключения для них будет показан статус `NULL` в таблице.
|
||||
|
||||
В системной таблице [system.clusters](../../operations/system-tables/clusters.md) есть кластер с именем, как у реплицируемой базы, который состоит из всех реплик базы. Этот кластер обновляется автоматически при создании/удалении реплик, и его можно использовать для [Distributed](../../engines/table-engines/special/distributed.md#distributed) таблиц.
|
||||
|
||||
При создании новой реплики базы, эта реплика сама создаёт таблицы. Если реплика долго была недоступна и отстала от лога репликации — она сверяет свои локальные метаданные с актуальными метаданными в ZooKeeper, перекладывает лишние таблицы с данными в отдельную нереплицируемую базу (чтобы случайно не удалить что-нибудь лишнее), создаёт недостающие таблицы, обновляет имена таблиц, если были переименования. Данные реплицируются на уровне `ReplicatedMergeTree`, т.е. если таблица не реплицируемая, то данные реплицироваться не будут (база отвечает только за метаданные).
|
||||
|
||||
## Примеры использования {#usage-example}
|
||||
|
||||
Создадим реплицируемую базу на трех хостах:
|
||||
|
||||
``` sql
|
||||
node1 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','shard1','replica1');
|
||||
node2 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','shard1','other_replica');
|
||||
node3 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','other_shard','{replica}');
|
||||
```
|
||||
|
||||
Выполним DDL-запрос на одном из хостов:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE r.rmt (n UInt64) ENGINE=ReplicatedMergeTree ORDER BY n;
|
||||
```
|
||||
|
||||
Запрос выполнится на всех остальных хостах:
|
||||
|
||||
``` text
|
||||
┌─────hosts────────────┬──status─┬─error─┬─num_hosts_remaining─┬─num_hosts_active─┐
|
||||
│ shard1|replica1 │ 0 │ │ 2 │ 0 │
|
||||
│ shard1|other_replica │ 0 │ │ 1 │ 0 │
|
||||
│ other_shard|r1 │ 0 │ │ 0 │ 0 │
|
||||
└──────────────────────┴─────────┴───────┴─────────────────────┴──────────────────┘
|
||||
```
|
||||
|
||||
Кластер в системной таблице `system.clusters`:
|
||||
|
||||
``` sql
|
||||
SELECT cluster, shard_num, replica_num, host_name, host_address, port, is_local
|
||||
FROM system.clusters WHERE cluster='r';
|
||||
```
|
||||
|
||||
``` text
|
||||
┌─cluster─┬─shard_num─┬─replica_num─┬─host_name─┬─host_address─┬─port─┬─is_local─┐
|
||||

|
||||
│ r │ 2 │ 1 │ node2 │ 127.0.0.1 │ 9001 │ 0 │
|
||||

|
||||
└─────────┴───────────┴─────────────┴───────────┴──────────────┴──────┴──────────┘
|
||||
```
|
||||
|
||||
Создадим распределенную таблицу и вставим в нее данные:
|
||||
|
||||
``` sql
|
||||
node2 :) CREATE TABLE r.d (n UInt64) ENGINE=Distributed('r','r','rmt', n % 2);
|
||||
node3 :) INSERT INTO r SELECT * FROM numbers(10);
|
||||
node1 :) SELECT materialize(hostName()) AS host, groupArray(n) FROM r.d GROUP BY host;
|
||||
```
|
||||
|
||||
``` text
|
||||
┌─hosts─┬─groupArray(n)─┐
|
||||
│ node1 │ [1,3,5,7,9] │
|
||||
│ node2 │ [0,2,4,6,8] │
|
||||
└───────┴───────────────┘
|
||||
```
|
||||
|
||||
Добавление реплики:
|
||||
|
||||
``` sql
|
||||
node4 :) CREATE DATABASE r ENGINE=Replicated('some/path/r','other_shard','r2');
|
||||
```
|
||||
|
||||
Новая реплика автоматически создаст все таблицы, которые есть в базе, а старые реплики перезагрузят из ZooKeeper-а конфигурацию кластера:
|
||||
|
||||
``` text
|
||||
┌─cluster─┬─shard_num─┬─replica_num─┬─host_name─┬─host_address─┬─port─┬─is_local─┐
|
||||
│ r │ 1 │ 1 │ node3 │ 127.0.0.1 │ 9002 │ 0 │
|
||||
│ r │ 1 │ 2 │ node4 │ 127.0.0.1 │ 9003 │ 0 │
|
||||
│ r │ 2 │ 1 │ node2 │ 127.0.0.1 │ 9001 │ 0 │
|
||||
│ r │ 2 │ 2 │ node1 │ 127.0.0.1 │ 9000 │ 1 │
|
||||
└─────────┴───────────┴─────────────┴───────────┴──────────────┴──────┴──────────┘
|
||||
```
|
||||
|
||||
Распределенная таблица также получит данные от нового хоста:
|
||||
|
||||
```sql
|
||||
node2 :) SELECT materialize(hostName()) AS host, groupArray(n) FROM r.d GROUP BY host;
|
||||
```

При использовании алгоритма `hash` правая часть `JOIN` загружается в оперативную память.
|
||||
|
||||
При использовании алгоритма `partial_merge` сервер сортирует данные и сбрасывает их на диск. Работа алгоритма `merge` в ClickHouse немного отличается от классической реализации. Сначала ClickHouse сортирует правую таблицу по блокам на основе [ключей соединения](../../sql-reference/statements/select/join.md#select-join) и для отсортированных блоков строит индексы min-max. Затем он сортирует куски левой таблицы на основе ключей соединения и объединяет их с правой таблицей операцией `JOIN`. Созданные min-max индексы используются для пропуска тех блоков из правой таблицы, которые не участвуют в данной операции `JOIN`.

|
||||
2. Помещает загруженные данные в директорию `detached` таблицы `table_name`. Чтобы прикрепить эти данные к таблице, используйте запрос [ATTACH PARTITION\|PART](#alter_attach-partition).
|
||||
|
||||
Например:
|
||||
|
||||
1. FETCH PARTITION
|
||||
``` sql
|
||||
ALTER TABLE users FETCH PARTITION 201902 FROM '/clickhouse/tables/01-01/visits';
|
||||
ALTER TABLE users ATTACH PARTITION 201902;
|
||||
```
|
||||
2. FETCH PART
|
||||
``` sql
|
||||
ALTER TABLE users FETCH PART 201901_2_2_0 FROM '/clickhouse/tables/01-01/visits';
|
||||
ALTER TABLE users ATTACH PART 201901_2_2_0;
|
||||
```
|
||||
|
||||
Следует иметь в виду:
|
||||
|
||||
- Запрос `ALTER TABLE t FETCH PARTITION` не реплицируется. Он загружает партицию в директорию `detached` только на локальном сервере.
|
||||
- Запрос `ALTER TABLE t FETCH PARTITION|PART` не реплицируется. Он загружает партицию в директорию `detached` только на локальном сервере.
|
||||
- Запрос `ALTER TABLE t ATTACH` реплицируется — он добавляет данные в таблицу сразу на всех репликах. На одной из реплик данные будут добавлены из директории `detached`, а на других — из соседних реплик.
|
||||
|
||||
Перед загрузкой данных система проверяет, существует ли партиция и совпадает ли её структура со структурой таблицы. При этом автоматически выбирается наиболее актуальная реплика среди всех живых реплик.

## Неявные преобразования типов {#implicit-type-conversion}
|
||||
|
||||
Запросы `INNER JOIN`, `LEFT JOIN`, `RIGHT JOIN` и `FULL JOIN` поддерживают неявные преобразования типов для ключей соединения. Однако запрос не может быть выполнен, если не существует типа, к которому можно привести значения ключей с обеих сторон (например, нет типа, который бы одновременно вмещал в себя значения `UInt64` и `Int64`, или `String` и `Int32`).
|

**Пример**
|

Рассмотрим таблицу `t_1`:

При включённой настройке `join_algorithm = 'auto'`, после некоторого порога потребления памяти ClickHouse переходит к алгоритму [merge join](https://ru.wikipedia.org/wiki/Алгоритм_соединения_слиянием_сортированных_списков).

- `replace_query` — 将INSERT INTO` 查询转换为 `REPLACE INTO`的标志。如果 `replace_query=1`，查询被替换。
|
||||
|
||||
- `on_duplicate_clause` — The `ON DUPLICATE KEY on_duplicate_clause` 表达式被添加到 `INSERT` 查询。
|
||||
- `on_duplicate_clause` — 添加 `ON DUPLICATE KEY on_duplicate_clause` 表达式到 `INSERT` 查询。明确规定只能使用 `replace_query = 0` ，如果你同时设置replace_query = 1`和`on_duplicate_clause`，ClickHouse将产生异常。
|
||||
|
||||
Example: `INSERT INTO t (c1,c2) VALUES ('a', 2) ON DUPLICATE KEY UPDATE c2 = c2 + 1`, where `on_duplicate_clause` is `UPDATE c2 = c2 + 1`. See the MySQL documentation to find which `on_duplicate_clause` you can use with the `ON DUPLICATE KEY` clause.
|
||||
示例：`INSERT INTO t (c1,c2) VALUES ('a', 2) ON DUPLICATE KEY UPDATE c2 = c2 + 1`
|
||||
|
||||
To specify `on_duplicate_clause` you need to pass `0` to the `replace_query` parameter. If you simultaneously pass `replace_query = 1` and `on_duplicate_clause`, ClickHouse generates an exception.
|
||||
`on_duplicate_clause`这里是`UPDATE c2 = c2 + 1`。请查阅MySQL文档，来找到可以和`ON DUPLICATE KEY`一起使用的 `on_duplicate_clause`子句。
|
||||
|
||||
简单 `WHERE` 条款如 `=, !=, >, >=, <, <=` 当前在MySQL服务器上执行。
|
||||
简单的 `WHERE` 子句如 `=, !=, >, >=, <, <=` 将即时在MySQL服务器上执行。其余的条件和 `LIMIT` 只有在对MySQL的查询完成后，才会在ClickHouse中执行采样约束。
|
||||
|
||||
其余的条件和 `LIMIT` 只有在对MySQL的查询完成后，才会在ClickHouse中执行采样约束。
|
||||
支持使用`|`并列进行多副本查询，示例如下：
|
||||
|
||||
```sql
|
||||
SELECT name FROM mysql(`mysql{1|2|3}:3306`, 'mysql_database', 'mysql_table', 'user', 'password');
|
||||
```
|
||||
|
||||
或
|
||||
|
||||
```sql
|
||||
SELECT name FROM mysql(`mysql1:3306|mysql2:3306|mysql3:3306`, 'mysql_database', 'mysql_table', 'user', 'password');
|
||||
```
|
||||
|
||||
**返回值**
|
||||
|
||||
与原始MySQL表具有相同列的table对象。
|
||||

|
||||
|

!!! note "注意"
|
||||
在`INSERT`查询中为了区分`mysql(...)`与带有列名列表的表名的表函数，你必须使用关键字`FUNCTION`或`TABLE FUNCTION`。查看如下示例。
