ClickHouse supports multi-file configuration management. The main server configuration file is `/etc/clickhouse-server/config.xml` or `/etc/clickhouse-server/config.yaml`. Other files must be in the `/etc/clickhouse-server/config.d` directory. Note, that any configuration file can be written either in XML or YAML, but mixing formats in one file is not supported. For example, you can have main configs as `config.xml` and `users.xml` and write additional files in `config.d` and `users.d` directories in `.yaml`.
All XML files should have the same root element, usually `<yandex>`. As for YAML, `yandex:` should not be present, the parser will insert it automatically.

So even if you have `TcpExtListenOverflows` (from `nstat`) non zero and this counter grows for ClickHouse server it does not mean that this value need to be increased, since:
- usually if 4096 is not enough it shows some internal ClickHouse scaling issue, so it is better to report an issue.
- and it does not mean that the server can handle more connections later (and even if it could, by that moment clients may be gone or disconnected).

# Optional secured communication between ClickHouse and Zookeeper {#secured-communication-with-zookeeper}
You should specify `ssl.keyStore.location`, `ssl.keyStore.password` and `ssl.trustStore.location`, `ssl.trustStore.password` for communication with ClickHouse client over SSL. These options are available from Zookeeper version 3.5.2.
You can add `zookeeper.crt` to trusted certificates.
``` bash
sudo cp zookeeper.crt /usr/local/share/ca-certificates/zookeeper.crt
sudo update-ca-certificates
```
Client section in `config.xml` will look like:
``` xml
<client>
<certificateFile>/etc/clickhouse-server/client.crt</certificateFile>
<privateKeyFile>/etc/clickhouse-server/client.key</privateKeyFile>
<loadDefaultCAFile>true</loadDefaultCAFile>
<cacheSessions>true</cacheSessions>
<disableProtocols>sslv2,sslv3</disableProtocols>
<preferServerCiphers>true</preferServerCiphers>
<invalidCertificateHandler>
<name>RejectCertificateHandler</name>
</invalidCertificateHandler>
</client>
```
Add Zookeeper to ClickHouse config with some cluster and macros:
``` xml
<yandex>
<zookeeper>
<node>
<host>localhost</host>
<port>2281</port>
<secure>1</secure>
</node>
</zookeeper>
</yandex>
```
Start `clickhouse-server`. In logs you should see:
```text
<Trace> ZooKeeper: initialized, hosts: secure://localhost:2281
```
Prefix `secure://` indicates that connection is secured by SSL.
To ensure traffic is encrypted run `tcpdump` on secured port:
```bash
tcpdump -i any dst port 2281 -nnXS
```
And query in `clickhouse-client`:
```sql
SELECT * FROM system.zookeeper WHERE path = '/';
```
On unencrypted connection you will see in `tcpdump` output something like this:
```text
..../zookeeper/q
uota.
```
On encrypted connection you should not see this.

# Functions for Working with S2 Index {#s2index}
[S2](https://s2geometry.io/) is a geographical indexing system where all geographical data is represented on a three-dimensional sphere (similar to a globe).
In the S2 library points are represented as unit length vectors called S2 point indices (points on the surface of a three dimensional unit sphere) as opposed to traditional (latitude, longitude) pairs.
In the S2 library points are represented as the S2 Index - a specific number which encodes internally a point on the surface of a unit sphere, unlike traditional (latitude, longitude) pairs. To get the S2 point index for a given point specified in the format (latitude, longitude) use the [geoToS2](#geotos2) function. Also, you can use the [s2ToGeo](#s2togeo) function for getting geographical coordinates corresponding to the specified S2 point index.

ClickHouse поддерживает многофайловое управление конфигурацией. Основной конфигурационный файл сервера — `/etc/clickhouse-server/config.xml` или `/etc/clickhouse-server/config.yaml`. Остальные файлы должны находиться в директории `/etc/clickhouse-server/config.d`. Обратите внимание, что конфигурационные файлы могут быть записаны в форматах XML или YAML, но смешение этих форматов в одном файле не поддерживается. Например, можно хранить основные конфигурационные файлы как `config.xml` и `users.xml`, а дополнительные файлы записать в директории `config.d` и `users.d` в формате `.yaml`.
Все XML файлы должны иметь одинаковый корневой элемент, обычно `<yandex>`. Для YAML элемент `yandex:` должен отсутствовать, так как парсер вставляет его автоматически.

## listen_backlog {#server_configuration_parameters-listen_backlog}
Бэклог (размер очереди соединений, ожидающих принятия) прослушивающего сокета.
Значение по умолчанию: `4096` (как в linux [5.4+](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=19f92a030ca6d772ab44b22ee6a01378a8cb32d4)).
Обычно это значение незачем менять по следующим причинам:
- значение по умолчанию достаточно велико,
- для принятия соединения клиента у сервера есть отдельный поток.
Так что даже если у вас `TcpExtListenOverflows` (из `nstat`) ненулевой и растет для сервера ClickHouse, это не повод увеличивать значение по умолчанию, поскольку:
- обычно если 4096 недостаточно, это говорит о внутренних проблемах ClickHouse с масштабированием, так что лучше сообщить о проблеме,
- и это не значит, что сервер сможет принять еще больше подключений в дальнейшем (а если и сможет, клиенты, вероятно, уже отсоединятся).

# Функции для работы с индексами S2 {#s2index}
[S2](https://s2geometry.io/) — это система геокодирования, в которой все географические данные представлены на трехмерной сфере (аналогично глобусу).
В библиотеке S2 точки представлены в виде индекса S2 — определенного числа, которое внутренне кодирует точку на поверхности трехмерной единичной сферы, в отличие от традиционных пар (широта, долгота). Чтобы получить индекс S2 для точки, заданной в формате (широта, долгота), используйте функцию [geoToS2](#geotools2). Также вы можете использовать функцию [s2togeo](#s2togeo) для получения географических координат, соответствующих заданному S2 индексу точки.
## geoToS2 {#geotos2}
Возвращает [S2](#s2index) индекс точки, соответствующий заданным координатам в формате `(долгота, широта)`.
**Синтаксис**
``` sql
geoToS2(lon, lat)
```
**Аргументы**
- `lon` — долгота. [Float64](../../../sql-reference/data-types/float.md).
- `lat` — широта. [Float64](../../../sql-reference/data-types/float.md).
**Возвращаемое значение**
- S2 индекс точки.
Тип: [UInt64](../../../sql-reference/data-types/int-uint.md).
**Пример**
Запрос:
``` sql
SELECT geoToS2(37.79506683, 55.71290588) AS s2Index;

# DESCRIBE TABLE Statement {#misc-describe-table}
# DESCRIBE TABLE {#misc-describe-table}
Возвращает описание столбцов таблицы.
**Синтаксис**
``` sql
DESC|DESCRIBE TABLE [db.]table [INTO OUTFILE filename] [FORMAT format]
```
Возвращает описание столбцов таблицы.
Запрос `DESCRIBE` для каждого столбца таблицы возвращает строку со следующими значениями типа [String](../../sql-reference/data-types/string.md):
Результат запроса содержит столбцы (все столбцы имеют тип String):
- `name` — имя столбца таблицы;
- `type`— тип столбца;
- `default_type` — в каком виде задано [выражение для значения по умолчанию](../../sql-reference/statements/create/table.md#create-default-values): `DEFAULT`, `MATERIALIZED` или `ALIAS`. Столбец содержит пустую строку, если значение по умолчанию не задано.
- `name` — имя столбца;
- `type` — тип столбца;
- `default_type` — вид [выражения для значения по умолчанию](../../sql-reference/statements/create/table.md#create-default-values): `DEFAULT`, `MATERIALIZED` или `ALIAS`. Если значение по умолчанию не задано, то возвращается пустая строка;
- `default_expression` — значение, заданное в секции `DEFAULT`;
- `comment_expression` — комментарий к столбцу.
- `comment` — [комментарий](../../sql-reference/statements/alter/column.md#alter_comment-column);
- `codec_expression` — [кодек](../../sql-reference/statements/create/table.md#codecs), который применяется к столбцу;
- `ttl_expression` — выражение [TTL](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-ttl);
- `is_subcolumn` — флаг, который равен `1` для внутренних подстолбцов. Он появляется в результате, только если описание подстолбцов разрешено настройкой [describe_include_subcolumns](../../operations/settings/settings.md#describe_include_subcolumns).
Вложенные структуры данных выводятся в «развёрнутом» виде. То есть, каждый столбец - по отдельности, с именем через точку.
Каждый столбец [Nested](../../sql-reference/data-types/nested-data-structures/nested.md) структур описывается отдельно. Перед его именем ставится имя родительского столбца с точкой.
Чтобы отобразить внутренние подстолбцы других типов данных, нужно включить настройку [describe_include_subcolumns](../../operations/settings/settings.md#describe_include_subcolumns).
**Пример**
Запрос:
``` sql
CREATE TABLE describe_example (
id UInt64, text String DEFAULT 'unknown' CODEC(ZSTD),
user Tuple (name String, age UInt8)
) ENGINE = MergeTree() ORDER BY id;
DESCRIBE TABLE describe_example;
DESCRIBE TABLE describe_example SETTINGS describe_include_subcolumns=1;
```
Результат:
``` text
┌─name─┬─type──────────────────────────┬─default_type─┬─default_expression─┬─comment─┬─codec_expression─┬─ttl_expression─┐
│ id │ UInt64 │ │ │ │ │ │
│ text │ String │ DEFAULT │ 'unknown' │ │ ZSTD(1) │ │
│ user │ Tuple(name String, age UInt8) │ │ │ │ │ │
└──────┴───────────────────────────────┴──────────────┴────────────────────┴─────────┴──────────────────┴────────────────┘
```
Второй запрос дополнительно выводит информацию о подстолбцах:
``` text
┌─name──────┬─type──────────────────────────┬─default_type─┬─default_expression─┬─comment─┬─codec_expression─┬─ttl_expression─┬─is_subcolumn─┐
│ id │ UInt64 │ │ │ │ │ │ 0 │
│ text │ String │ DEFAULT │ 'unknown' │ │ ZSTD(1) │ │ 0 │
│ user │ Tuple(name String, age UInt8) │ │ │ │ │ │ 0 │
│ user.name │ String │ │ │ │ │ │ 1 │
│ user.age │ UInt8 │ │ │ │ │ │ 1 │

@ -6,7 +6,7 @@ toc_title: PREWHERE
Prewhere — это оптимизация для более эффективного применения фильтрации. Она включена по умолчанию, даже если секция `PREWHERE` явно не указана. В этом случае работает автоматическое перемещение части выражения из [WHERE](where.md) до стадии prewhere. Роль секции `PREWHERE` только для управления этой оптимизацией, если вы думаете, что знаете, как сделать перемещение условия лучше, чем это происходит по умолчанию.
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.
