# Профили настроек
|
||
|
||
Профили настроек - это множество настроек, сгруппированных под одним именем. Для каждого пользователя ClickHouse указывается некоторый профиль.
|
||
Все настройки профиля можно применить, установив настройку `profile`.
|
||
|
||
Пример:
|
||
|
||
Установить профиль `web`.
|
||
|
||
``` sql
|
||
SET profile = 'web'
|
||
```
|
||
|
||
Профили настроек объявляются в конфигурационном файле пользователей. Обычно это `users.xml`.
|
||
|
||
Пример:
|
||
|
||
```xml
|
||
<!-- Settings profiles -->
|
||
<profiles>
|
||
<!-- Default settings -->
|
||
<default>
|
||
<!-- The maximum number of threads when running a single query. -->
|
||
<max_threads>8</max_threads>
|
||
</default>
|
||
|
||
<!-- Settings for quries from the user interface -->
|
||
<web>
|
||
<max_rows_to_read>1000000000</max_rows_to_read>
|
||
<max_bytes_to_read>100000000000</max_bytes_to_read>
|
||
|
||
<max_rows_to_group_by>1000000</max_rows_to_group_by>
|
||
<group_by_overflow_mode>any</group_by_overflow_mode>
|
||
|
||
<max_rows_to_sort>1000000</max_rows_to_sort>
|
||
<max_bytes_to_sort>1000000000</max_bytes_to_sort>
|
||
|
||
<max_result_rows>100000</max_result_rows>
|
||
<max_result_bytes>100000000</max_result_bytes>
|
||
<result_overflow_mode>break</result_overflow_mode>
|
||
|
||
<max_execution_time>600</max_execution_time>
|
||
<min_execution_speed>1000000</min_execution_speed>
|
||
<timeout_before_checking_execution_speed>15</timeout_before_checking_execution_speed>
|
||
|
||
<max_columns_to_read>25</max_columns_to_read>
|
||
<max_temporary_columns>100</max_temporary_columns>
|
||
<max_temporary_non_const_columns>50</max_temporary_non_const_columns>
|
||
|
||
<max_subquery_depth>2</max_subquery_depth>
|
||
<max_pipeline_depth>25</max_pipeline_depth>
|
||
<max_ast_depth>50</max_ast_depth>
|
||
<max_ast_elements>100</max_ast_elements>
|
||
|
||
<readonly>1</readonly>
|
||
</web>
|
||
</profiles>
|
||
```
|
||
|
||
В примере задано два профиля: `default` и `web`. Профиль `default` имеет специальное значение - он всегда обязан присутствовать и применяется при запуске сервера. То есть, профиль `default` содержит настройки по умолчанию. Профиль `web` - обычный профиль, который может быть установлен с помощью запроса `SET` или с помощью параметра URL при запросе по HTTP.
|
||
|
||
Профили настроек могут наследоваться от друг-друга - это реализуется указанием настройки `profile` перед остальными настройками, перечисленными в профиле.
