- `move_factor` — when the amount of available space gets lower than this factor, data automatically start to move on the next volume if any (by default, 0.1).
- `prefer_not_to_merge` — Disables merging of data parts on this volume. When this setting is enabled, merging data on this volume is not allowed. This allows controlling how ClickHouse works with slow disks.

A block size of 1024 KB is sufficient for all RAID configurations.
A block size of 64 KB is sufficient for most RAID configurations. The average clickhouse-server write size is approximately 1 MB (1024 KB), and thus the recommended stripe size is also 1 MB. The block size can be optimized if needed when set to 1 MB divided by the number of non-parity disks in the RAID array, such that each write is parallelized across all available non-parity disks.
Never set the block size too small or too large.
You can use RAID-0 on SSD.

The function works fairly slowly (SHA-1 processes about 5 million short strings per second per processor core, while SHA-224 and SHA-256 process about 2.2 million).
We recommend using this function only in cases when you need a specific hash function and you can’t select it.
Even in these cases, we recommend applying the function offline and pre-calculating values when inserting them into the table, instead of applying it in SELECTS.

The `ALTER` query lets you create and delete separate elements (columns) in nested data structures, but not whole nested data structures. To add a nested data structure, you can add columns with a name like `name.nested_name` and the type `Array(T)`. A nested data structure is equivalent to multiple array columns with a name that has the same prefix before the dot.

Materialized views in ClickHouse use **column names** instead of column order during insertion into destination table.

A safe practice would be to add aliases for every column when using Materialized views.
!!! important "Important"
Materialized views in ClickHouse are implemented more like insert triggers. If there’s some aggregation in the view query, it’s applied only to the batch of freshly inserted data. Any changes to existing data of source table (like update, delete, drop partition, etc.) does not change the materialized view.
If you specify `POPULATE`, the existing table data is inserted in the view when creating it, as if making a `CREATE TABLE ... AS SELECT ...` . Otherwise, the query contains only the data inserted in the table after creating the view. We **do not recommend** using POPULATE, since data inserted in the table during the view creation will not be inserted in it.

For example, if `GROUP BY` is set, data is aggregated during insertion, but only within a single packet of inserted data. The data won’t be further aggregated. The exception is when using an `ENGINE` that independently performs data aggregation, such as `SummingMergeTree`.

The execution of [ALTER](../../../sql-reference/statements/alter/view.md) queries on materialized views has limitations, so they might be inconvenient. If the materialized view uses the construction `TO [db.]name`, you can `DETACH` the view, run `ALTER` for the target table, and then `ATTACH` the previously detached (`DETACH`) view.

@ -6,7 +6,7 @@ toc_title: PREWHERE
Prewhere is an optimization to apply filtering more efficiently. It is enabled by default even if `PREWHERE` clause is not specified explicitly. It works by automatically moving part of [WHERE](../../../sql-reference/statements/select/where.md) condition to prewhere stage. The role of `PREWHERE` clause is only to control this optimization if you think that you know how to do it better than it happens by default.
With prewhere optimization, at first only the columns necessary for executing prewhere expression are read. Then the other columns are read that are needed for running the rest of the query, but only those blocks where the prewhere expression is “true” at least for some rows. If there are a lot of blocks where prewhere expression is “false” for all rows and prewhere needs less columns than other parts of query, this often allows to read a lot less data from disk for query execution.

A query may simultaneously specify `PREWHERE` and `WHERE`. In this case, `PREWHERE` precedes `WHERE`.
If the `optimize_move_to_prewhere` setting is set to 0, heuristics to automatically move parts of expressions from `WHERE` to `PREWHERE` are disabled.
If the [optimize_move_to_prewhere](../../../operations/settings/settings.md#optimize_move_to_prewhere) setting is set to 0, heuristics to automatically move parts of expressions from `WHERE` to `PREWHERE` are disabled.
If query has [FINAL](from.md#select-from-final) modifier, the `PREWHERE` optimization is not always correct. It is enabled only if both settings [optimize_move_to_prewhere](../../../operations/settings/settings.md#optimize_move_to_prewhere) and [optimize_move_to_prewhere_if_final](../../../operations/settings/settings.md#optimize_move_to_prewhere_if_final) are turned on.

The `PREWHERE` section is executed before` FINAL`, so the results of `FROM FINAL` queries may be skewed when using` PREWHERE` with fields not in the `ORDER BY` section of a table.

Если в результате слияния размер куска ожидается больше, чем max_data_part_size_bytes, то этот кусок будет записан в следующий том. В основном эта функция позволяет хранить новые / мелкие куски на горячем (SSD) томе и перемещать их на холодный (HDD) том, когда они достигают большого размера. Не используйте этот параметр, если политика имеет только один том.

[H3](https://eng.uber.com/h3/) — это система геокодирования, которая делит поверхность Земли на равные шестигранные ячейки. Система поддерживает иерархию (вложенность) ячеек, т.е. каждый "родительский" шестигранник может быть поделен на семь одинаковых вложенных "дочерних" шестигранников, и так далее.
Уровень вложенности назвается `разрешением` и может принимать значение от `0` до `15`, где `0` соответствует `базовым` ячейкам самого верхнего уровня (наиболее крупным).
Уровень вложенности называется "разрешением" и может принимать значение от `0` до `15`, где `0` соответствует "базовым" ячейкам самого верхнего уровня (наиболее крупным).

Материализованное представление устроено следующим образом: при вставке данных в таблицу, указанную в SELECT-е, кусок вставляемых данных преобразуется этим запросом SELECT, и полученный результат вставляется в представление.
!!! important "Важно"
Материализованные представления в ClickHouse используют **имена столбцов** вместо порядка следования столбцов при вставке в целевую таблицу. Если в результатах запроса `SELECT` некоторые имена столбцов отсутствуют, то ClickHouse использует значение по умолчанию, даже если столбец не является [Nullable](../../data-types/nullable.md). Безопасной практикой при использовании материализованных представлений считается добавление псевдонимов для каждого столбца.
Материализованные представления в ClickHouse больше похожи на `after insert` триггеры. Если в запросе материализованного представления есть агрегирование, оно применяется только к вставляемому блоку записей. Любые изменения существующих данных исходной таблицы (например обновление, удаление, удаление раздела и т.д.) не изменяют материализованное представление.
Если указано `POPULATE`, то при создании представления, в него будут вставлены имеющиеся данные таблицы, как если бы был сделан запрос `CREATE TABLE ... AS SELECT ...` . Иначе, представление будет содержать только данные, вставляемые в таблицу после создания представления. Не рекомендуется использовать POPULATE, так как вставляемые в таблицу данные во время создания представления, не попадут в него.
Если указано `POPULATE`, то при создании представления в него будут добавлены данные, уже содержащиеся в исходной таблице, как если бы был сделан запрос `CREATE TABLE ... AS SELECT ...` . Если `POPULATE` не указано, представление будет содержать только данные, добавленные в таблицу после создания представления. Использовать `POPULATE` не рекомендуется, так как в представление не попадут данные, добавляемые в таблицу во время создания представления.
Запрос `SELECT` может содержать `DISTINCT`, `GROUP BY`, `ORDER BY`, `LIMIT`… Следует иметь ввиду, что соответствующие преобразования будут выполняться независимо, на каждый блок вставляемых данных. Например, при наличии `GROUP BY`, данные будут агрегироваться при вставке, но только в рамках одной пачки вставляемых данных. Далее, данные не будут доагрегированы. Исключение - использование ENGINE, производящего агрегацию данных самостоятельно, например, `SummingMergeTree`.

@ -8,17 +8,19 @@ Prewhere — это оптимизация для более эффективн
При оптимизации prewhere сначала читываются только те столбцы, которые необходимы для выполнения выражения prewhere. Затем читаются другие столбцы, необходимые для выполнения остальной части запроса, но только те блоки, в которых находится выражение prewhere «верно» по крайней мере для некоторых рядов. Если есть много блоков, где выражение prewhere «ложно» для всех строк и для выражения prewhere требуется меньше столбцов, чем для других частей запроса, это часто позволяет считывать гораздо меньше данных с диска для выполнения запроса.
## Управление prewhere вручную {#controlling-prewhere-manually}
## Управление PREWHERE вручную {#controlling-prewhere-manually}
`PREWHERE` имеет смысл использовать, если есть условия фильтрации, которые использует меньшинство столбцов из тех, что есть в запросе, но достаточно сильно фильтрует данные. Таким образом, сокращается количество читаемых данных.
