Значения настроек всех MergeTree таблиц собраны в таблице `system.merge_tree_settings`. Их можно переопределить в разделе `merge_tree` файла `config.xml` или задать в секции `SETTINGS` каждой таблицы.
2020-04-09 21:45:29 +00:00
2020-04-10 13:38:58 +00:00
Пример переопределения в `config.xml`:
``` text
2020-04-09 21:45:29 +00:00
<merge_tree>
<max_suspicious_broken_parts>5</max_suspicious_broken_parts>
</merge_tree>

Команда `Insert` создает один или несколько блоков (кусков). При вставке в Replicated таблицы ClickHouse для [дедупликации вставок](../../engines/table-engines/mergetree-family/replication.md) записывает в Zookeeper хеш-суммы созданных кусков. Но хранятся только последние `replicated_deduplication_window` хеш-сумм. Самые старые хеш-суммы удаляются из Zookeeper.
2021-07-29 15:20:55 +00:00
Большое значение `replicated_deduplication_window` замедляет `Insert`, так как приходится сравнивать большее количество хеш-сумм.

Аналогично [replicated_deduplication_window](#replicated-deduplication-window), настройка `replicated_deduplication_window_seconds` задает время хранения хеш-сумм блоков для дедупликции `Insert`. Хеш-суммы старше значения `replicated_deduplication_window_seconds` удаляются из Zookeeper, даже если количество оставшихся хеш-сумм станет меньше чем `replicated_deduplication_window`.

После объединения нескольких кусков в один новый ClickHouse помечает исходные куски как неактивные и удаляет их по прошествии `old_parts_lifetime` секунд.
Неактивные куски удаляются, если они не нужны для текущих запросов, т.е. если счетчик ссылок куска `refcount` имеет нулевое значение.

При записи нового куска `fsync` не вызывается, поэтому неактивные куски удаляются позже. Это значит, что некоторое время новый кусок находится только в оперативной памяти сервера (кеш ОС). Если сервер перезагрузится спонтанно, новый слитый кусок может испортиться или потеряться.
2020-04-09 21:45:29 +00:00
2021-07-29 15:20:55 +00:00
Во время запуска сервер ClickHouse проверяет целостность кусков.
Если новый (слитый) кусок поврежден, ClickHouse возвращает неактивные куски в список активных и позже снова выполняет слияние. В этом случае испорченный кусок получает новое имя (добавляется префикс `broken_`) и попадает в каталог `detached`.

Если проверка целостности не выявляет проблем в слитом куске, то исходные неактивные куски переименовываются (добавляется префикс `ignored_`) и перемещаются в каталог `detached`.
Стандартное для Linux значение `dirty_expire_centisecs` — 30 секунд. Это максимальное время, в течение которого записанные данные хранятся только в оперативной памяти. Если нагрузка на дисковую систему большая, то данные записываются намного позже. Значение 480 секунд подобрали экспериментальным путем — это время, за которое новый кусок гарантированно запишется на диск.

## max_replicated_fetches_network_bandwidth {#max_replicated_fetches_network_bandwidth}
Ограничивает максимальную скорость скачивания данных в сети (в байтах в секунду) для синхронизаций между [репликами](../../engines/table-engines/mergetree-family/replication.md). Настройка применяется к конкретной таблице, в отличие от [max_replicated_fetches_network_bandwidth_for_server](settings.md#max_replicated_fetches_network_bandwidth_for_server), которая применяется к серверу.
2021-09-03 12:53:14 +00:00
Можно ограничить скорость обмена данными как для всего сервера, так и для конкретной таблицы, но для этого значение табличной настройки должно быть меньше серверной. Иначе сервер будет учитывать только настройку `max_replicated_fetches_network_bandwidth_for_server`.
2021-09-03 12:53:14 +00:00
Настройка соблюдается неточно.
2021-09-03 12:53:14 +00:00
Возможные значения:
- Любое целое положительное число.
- 0 — Скорость не ограничена.

Значение по умолчанию: `0`.

## max_replicated_sends_network_bandwidth {#max_replicated_sends_network_bandwidth}
Ограничивает максимальную скорость отправки данных по сети (в байтах в секунду) для синхронизации между [репликами](../../engines/table-engines/mergetree-family/replication.md). Настройка применяется к конкретной таблице, в отличие от [max_replicated_sends_network_bandwidth_for_server](settings.md#max_replicated_sends_network_bandwidth_for_server), которая применяется к серверу.
2021-09-03 12:53:14 +00:00
Можно ограничить скорость обмена данными как для всего сервера, так и для конкретной таблицы, но для этого значение табличной настройки должно быть меньше серверной. Иначе сервер будет учитывать только настройку `max_replicated_sends_network_bandwidth_for_server`.

Возможные значения:
- Любое целое положительное число.
- 0 — Скорость не ограничена.

Слияния резервируют дисковое пространство, удваивая суммарный размер кусков в слиянии. Поэтому при малом объеме свободного места на диске может сложиться ситуация, когда свободное место есть, но оно уже зарезервировано текущими слияниями. Из-за этого другие слияния не начинаются, и количество маленьких кусков в партиции растет с каждым запросом `INSERT`.

Слияние читает строки из кусков блоками по `merge_max_block_size` строк, производит слияние и записывает результат в новый кусок. Читаемый блок помещается в оперативную память, т.е. `merge_max_block_size` влияет на размер оперативной памяти, необходимой для слияния. Таким образом, слияния могут потреблять большое количество оперативной памяти для таблиц, хранящих очень большие строки (если средний размер строки 100кб, то при слиянии 10 кусков будет использовано (100кб * 10 * 8192) =~ 8ГБ оперативной памяти). Уменьшив `merge_max_block_size`, можно сократить размер оперативной памяти, необходимой для слияния, но при этом процесс слияния замедлится.

На старте ClickHouse читает все куски из всех таблиц (читает файлы с метаданными кусков), чтобы построить в оперативной памяти список всех кусков. В некоторых системах с большим количеством кусков этот процесс может занимать длительное время. Это время можно сократить, увеличив `max_part_loading_threads` (если при этом хватает ресурсов процессора и диска).

Позволяет использовать число с плавающей запятой в качестве ключа партиционирования.
Возможные значения:

## check_sample_column_is_correct {#check_sample_column_is_correct}
Разрешает проверку того, что тип данных столбца для сэмплирования или выражения сэмплирования при создании таблицы верный. Тип данных должен соответствовать одному из беззнаковых [целочисленных типов](../../sql-reference/data-types/int-uint.md): `UInt8`, `UInt16`, `UInt32`, `UInt64`.
Возможные значения:
- true — проверка включена.
- false — проверка при создании таблицы не проводится.
Значение по умолчанию: `true`.
2021-07-29 15:20:55 +00:00
По умолчанию сервер ClickHouse при создании таблицы проверяет тип данных столбца для сэмплирования или выражения сэмплирования. Если уже существуют таблицы с некорректным выражением сэмплирования, то чтобы не возникало исключение при запуске сервера, установите `check_sample_column_is_correct` в значение `false`.
## min_bytes_to_rebalance_partition_over_jbod {#min-bytes-to-rebalance-partition-over-jbod}
Устанавливает минимальное количество байтов для обеспечения балансировки при распределении новых больших кусков данных по дискам тома [JBOD](https://en.wikipedia.org/wiki/Non-RAID_drive_architectures).
Возможные значения:
- Положительное целое число.
- 0 — балансировка отключена.
Значение по умолчанию: `0`.
**Использование**
2022-08-29 18:25:46 +00:00
Значение настройки `min_bytes_to_rebalance_partition_over_jbod` должно быть не меньше значения настройки [max_bytes_to_merge_at_max_space_in_pool](../../operations/settings/merge-tree-settings.md#max-bytes-to-merge-at-max-space-in-pool) / 1024. Иначе ClickHouse сгенерирует исключение.
2021-11-05 18:23:16 +00:00
## detach_not_byte_identical_parts {#detach_not_byte_identical_parts}
Настраивает отключение куска данных после выполнения слияния или мутации, если на одной реплике его содержимое побайтно не совпадает с кусками на других репликах. Если настройка отключена, то кусок удаляется. Активируйте это поведение, если хотите анализировать такие куски позже.
2021-11-05 18:23:16 +00:00
2021-11-09 19:37:36 +00:00
Эта настройка применяется к таблицам `MergeTree` с включенной [репликацией данных](../../engines/table-engines/mergetree-family/replication.md).
2021-11-05 18:23:16 +00:00
Возможные значения:
- 0 — куски данных удаляются.
- 1 — куски данных открепляются.
