# EmbeddedRocksDB Engine {#EmbeddedRocksDB-engine}
This engine allows integrating ClickHouse with [rocksdb](http://rocksdb.org/).
`EmbeddedRocksDB` lets you:
## Creating a Table {#table_engine-EmbeddedRocksDB-creating-a-table}
``` sql
CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
(
name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
...
) ENGINE = EmbeddedRocksDB PRIMARY KEY(primary_key_name)
```
Required parameters:
- `primary_key_name` – any column name in the column list.
Example:
``` sql
CREATE TABLE test
(
`key` String,
`v1` UInt32,
`v2` String,
`v3` Float32,
)
ENGINE = EmbeddedRocksDB
PRIMARY KEY key
```
## Description {#description}
- `primary key` must be specified, it only supports one column in primary key. The primary key will serialized in binary as rocksdb key.
- columns other than the primary key will be serialized in binary as rocksdb value in corresponding order.
- queries with key `equals` or `in` filtering will be optimized to multi keys lookup from rocksdb.

# timeSeriesGroupRateSum {#agg-function-timeseriesgroupratesum}
Syntax: `timeSeriesGroupRateSum(uid, ts, val)`
Similarly to [timeSeriesGroupSum](../../../sql-reference/aggregate-functions/reference/timeseriesgroupsum.md), `timeSeriesGroupRateSum` calculates the rate of time-series and then sum rates together.
Also, timestamp should be in ascend order before use this function.
Applying this function to the data from the `timeSeriesGroupSum` example, you get the following result:
``` text
[(2,0),(3,0.1),(7,0.3),(8,0.3),(12,0.3),(17,0.3),(18,0.3),(24,0.3),(25,0.1)]

# timeSeriesGroupSum {#agg-function-timeseriesgroupsum}
Syntax: `timeSeriesGroupSum(uid, timestamp, value)`
`timeSeriesGroupSum` can aggregate different time series that sample timestamp not alignment.
It will use linear interpolation between two sample timestamp and then sum time-series together.
- `uid` is the time series unique id, `UInt64`.
- `timestamp` is Int64 type in order to support millisecond or microsecond.
- `value` is the metric.
The function returns array of tuples with `(timestamp, aggregated_value)` pairs.
Before using this function make sure `timestamp` is in ascending order.
Example:
``` text
┌─uid─┬─timestamp─┬─value─┐
│ 1 │ 2 │ 0.2 │
│ 1 │ 7 │ 0.7 │
│ 1 │ 12 │ 1.2 │
│ 1 │ 17 │ 1.7 │
│ 1 │ 25 │ 2.5 │
│ 2 │ 3 │ 0.6 │
│ 2 │ 8 │ 1.6 │
│ 2 │ 12 │ 2.4 │
│ 2 │ 18 │ 3.6 │
│ 2 │ 24 │ 4.8 │
└─────┴───────────┴───────┘
```
``` sql
CREATE TABLE time_series(
uid UInt64,
timestamp Int64,
value Float64
) ENGINE = Memory;
INSERT INTO time_series VALUES
(1,2,0.2),(1,7,0.7),(1,12,1.2),(1,17,1.7),(1,25,2.5),
(2,3,0.6),(2,8,1.6),(2,12,2.4),(2,18,3.6),(2,24,4.8);
SELECT timeSeriesGroupSum(uid, timestamp, value)
FROM (
SELECT * FROM time_series order by timestamp ASC
);
```
And the result will be:
``` text
[(2,0.2),(3,0.9),(7,2.1),(8,2.4),(12,3.6),(17,5.1),(18,5.4),(24,7.2),(25,2.5)]

## reinterpretAsUUID {#reinterpretasuuid}
This function accepts FixedString, and returns UUID. Takes 16 bytes string. If the string isn't long enough, the functions work as if the string is padded with the necessary number of null bytes to the end. If the string longer than 16 bytes, the extra bytes at the end are ignored.
This function accepts 16 bytes string, and returns UUID containing bytes representing the corresponding value in network byte order (big-endian). If the string isn't long enough, the functions work as if the string is padded with the necessary number of null bytes to the end. If the string longer than 16 bytes, the extra bytes at the end are ignored.
**Syntax**
``` sql
reinterpretAsUUID(fixed_string)
```
**Parameters**
- `fixed_string` — Big-endian byte string. [FixedString](../../sql-reference/data-types/fixedstring.md#fixedstring).
**Returned value**
- The UUID type value. [UUID](../../sql-reference/data-types/uuid.md#uuid-data-type).
**Examples**
String to UUID.

`timeSeriesGroupSum` puede agregar diferentes series de tiempo que muestran la marca de tiempo no la alineación.
Utilizará la interpolación lineal entre dos marcas de tiempo de muestra y luego sumará series temporales juntas.
- `uid` es la identificación única de la serie temporal, `UInt64`.
- `timestamp` es el tipo Int64 para admitir milisegundos o microsegundos.
- `value` es la métrica.
La función devuelve una matriz de tuplas con `(timestamp, aggregated_value)` par.
Antes de utilizar esta función, asegúrese de `timestamp` está en orden ascendente.
Ejemplo:
``` text

# timeSeriesGroupSum {#agg-function-timeseriesgroupsum}
Синтаксис: `timeSeriesGroupSum(uid, timestamp, value)`
`timeSeriesGroupSum` агрегирует временные ряды в которых не совпадают моменты.
Функция использует линейную интерполяцию между двумя значениями времени, а затем суммирует значения для одного и того же момента (как измеренные так и интерполированные) по всем рядам.
- `uid` уникальный идентификатор временного ряда, `UInt64`.
- `timestamp` имеет тип `Int64` чтобы можно было учитывать милли и микросекунды.
- `value` представляет собой значение метрики.
Функция возвращает массив кортежей с парами `(timestamp, aggregated_value)`.
Временные ряды должны быть отсортированы по возрастанию `timestamp`.
Пример:
``` text
┌─uid─┬─timestamp─┬─value─┐
│ 1 │ 2 │ 0.2 │
│ 1 │ 7 │ 0.7 │
│ 1 │ 12 │ 1.2 │

Если строка длиннее, чем шестнадцать байт, то игнорируются лишние байты с конца.
**Синтаксис**
``` sql
reinterpretAsUUID(fixed_string)
```
**Параметры**
- `fixed_string` — cтрока с big-endian порядком байтов. [FixedString](../../sql-reference/data-types/fixedstring.md#fixedstring).
**Возвращаемое значение**
- Значение типа [UUID](../../sql-reference/data-types/uuid.md#uuid-data-type).
**Примеры**
Интерпретация строки как UUID.
Запрос:
``` sql
SELECT reinterpretAsUUID(reverse(unhex('000102030405060708090a0b0c0d0e0f')))
```
Результат:
``` text
┌─reinterpretAsUUID(reverse(unhex('000102030405060708090a0b0c0d0e0f')))─┐
│ 08090a0b-0c0d-0e0f-0001-020304050607 │

# 数据备份 {#data-backup}
碌莽禄While: [复制](../engines/table-engines/mergetree-family/replication.md) provides protection from hardware failures, it does not protect against human errors: accidental deletion of data, deletion of the wrong table or a table on the wrong cluster, and software bugs that result in incorrect data processing or data corruption. In many cases mistakes like these will affect all replicas. ClickHouse has built-in safeguards to prevent some types of mistakes — for example, by default [您不能使用类似MergeTree的引擎删除包含超过50Gb数据的表](https://github.com/ClickHouse/ClickHouse/blob/v18.14.18-stable/programs/server/config.xml#L322-L330). 但是，这些保障措施并不涵盖所有可能的情况，可以规避。
尽管[副本](../engines/table-engines/mergetree-family/replication.md) 可以预防硬件错误带来的数据丢失, 但是它不能防止人为操作的错误: 意外删除数据, 删除错误的 table 或者删除错误 cluster 上的 table, 可以导致错误数据处理错误或者数据损坏的 bugs. 这类意外可能会影响所有的副本. ClickHouse 有内建的保障措施可以预防一些错误 — 例如, 默认情况下[您不能使用类似MergeTree的引擎删除包含超过50Gb数据的表](https://github.com/ClickHouse/ClickHouse/blob/v18.14.18-stable/programs/server/config.xml#L322-L330). 但是，这些保障措施不能涵盖所有可能的情况，并且可以规避。

每家公司都有不同的可用资源和业务需求，因此没有适合各种情况的ClickHouse备份和恢复通用解决方案。 什么适用于一千兆字节的数据可能不会为几十pb的工作。 有多种可能的方法有自己的优点和缺点，这将在下面讨论。 这是一个好主意，使用几种方法，而不是只是一个，以弥补其各种缺点。

!!! note "注"
请记住，如果您备份了某些内容并且从未尝试过还原它，那么当您实际需要它时（或者至少需要比业务能够容忍的时间更长），恢复可能无法正常工作。 因此，无论您选择哪种备份方法，请确保自动还原过程，并定期在备用ClickHouse群集上练习。
## 将源数据复制到其他地方 {#duplicating-source-data-somewhere-else}
通常被摄入到ClickHouse的数据是通过某种持久队列传递的，例如 [Apache Kafka](https://kafka.apache.org). 在这种情况下，可以配置一组额外的订阅服务器，这些订阅服务器将在写入ClickHouse时读取相同的数据流，并将其存储在冷存储中。 大多数公司已经有一些默认的推荐冷存储，可能是对象存储或分布式文件系统，如 [HDFS](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html).

## 文件系统快照 {#filesystem-snapshots}
某些本地文件系统提供快照功能（例如, [ZFS](https://en.wikipedia.org/wiki/ZFS)），但它们可能不是提供实时查询的最佳选择。 一个可能的解决方案是使用这种文件系统创建额外的副本，并将它们从 [分布](../engines/table-engines/special/distributed.md) 用于以下目的的表 `SELECT` 查询。 任何修改数据的查询都无法访问此类副本上的快照。 作为奖励，这些副本可能具有特殊的硬件配置，每个服务器附加更多的磁盘，这将是经济高效的。

[clickhouse-copier](utilities/clickhouse-copier.md) 是一个多功能工具，最初创建用于重新分片pb大小的表。 因为它可以在ClickHouse表和集群之间可靠地复制数据，所以它还可用于备份和还原数据。
对于较小的数据量，一个简单的 `INSERT INTO ... SELECT ...` 到远程表也可以工作。
## 部件操作 {#manipulations-with-parts}
ClickHouse允许使用 `ALTER TABLE ... FREEZE PARTITION ...` 查询以创建表分区的本地副本。 这是使用硬链接来实现 `/var/lib/clickhouse/shadow/` 文件夹中，所以它通常不会占用旧数据的额外磁盘空间。 创建的文件副本不由ClickHouse服务器处理，所以你可以把它们留在那里：你将有一个简单的备份，不需要任何额外的外部系统，但它仍然会容易出现硬件问题。 出于这个原因，最好将它们远程复制到另一个位置，然后删除本地副本。 分布式文件系统和对象存储仍然是一个不错的选择，但是具有足够大容量的正常附加文件服务器也可以工作（在这种情况下，传输将通过网络文件系统 [rsync](https://en.wikipedia.org/wiki/Rsync)).

## timeSeriesGroupSum(uid,timestamp,value) {#agg-function-timeseriesgroupsum}
`timeSeriesGroupSum` 可以聚合不同的时间序列，即采样时间戳不对齐。
它将在两个采样时间戳之间使用线性插值，然后将时间序列和在一起。
- `uid` 是时间序列唯一id, `UInt64`.
- `timestamp` 是Int64型，以支持毫秒或微秒。
- `value` 是指标。
函数返回元组数组 `(timestamp, aggregated_value)` 对。
在使用此功能之前，请确保 `timestamp` 按升序排列
示例:
``` text
┌─uid─┬─timestamp─┬─value─┐
│ 1 │ 2 │ 0.2 │
│ 1 │ 7 │ 0.7 │
│ 1 │ 12 │ 1.2 │
│ 1 │ 17 │ 1.7 │
│ 1 │ 25 │ 2.5 │
│ 2 │ 3 │ 0.6 │
│ 2 │ 8 │ 1.6 │
│ 2 │ 12 │ 2.4 │
│ 2 │ 18 │ 3.6 │
│ 2 │ 24 │ 4.8 │
└─────┴───────────┴───────┘
```
``` sql
CREATE TABLE time_series(
uid UInt64,
timestamp Int64,
value Float64
) ENGINE = Memory;
INSERT INTO time_series VALUES

(2,3,0.6),(2,8,1.6),(2,12,2.4),(2,18,3.6),(2,24,4.8);
SELECT timeSeriesGroupSum(uid, timestamp, value)
FROM (
SELECT * FROM time_series order by timestamp ASC
);
```
其结果将是:
``` text
[(2,0.2),(3,0.9),(7,2.1),(8,2.4),(12,3.6),(17,5.1),(18,5.4),(24,7.2),(25,2.5)]
```
## timeSeriesGroupRateSum(uid,ts,val) {#agg-function-timeseriesgroupratesum}
同样 `timeSeriesGroupSum`, `timeSeriesGroupRateSum` 计算时间序列的速率，然后将速率总和在一起。
此外，使用此函数之前，时间戳应该是上升顺序。
应用此功能从数据 `timeSeriesGroupSum` 例如，您将得到以下结果:
``` text
[(2,0),(3,0.1),(7,0.3),(8,0.3),(12,0.3),(17,0.3),(18,0.3),(24,0.3),(25,0.1)]
```
## avg(x) {#agg_function-avg}
计算平均值。
