ClickHouse is an open-source column-oriented database management system that allows the generation of analytical data reports in real-time.
|
||||
|
||||
ClickHouse manages extremely large volumes of data in a stable and sustainable manner. It currently powers [Yandex.Metrica](https://metrica.yandex.com/), world’s [second largest](http://w3techs.com/technologies/overview/traffic_analysis/all) web analytics platform, with over 13 trillion database records and over 20 billion events a day, generating customized reports on-the-fly, directly from non-aggregated data. This system was successfully implemented at [CERN’s LHCb experiment](https://www.yandex.com/company/press_center/press_releases/2012/2012-04-10/) to store and process metadata on 10bn events with over 1000 attributes per event registered in 2011.

### Start server instance with custom configuration
|
||||
|
||||
```bash
|
||||
$ docker run -d --name some-clickhouse-server --ulimit nofile=262144:262144 -v /path/to/your/config.xml:/etc/clickhouse-server/config.xml clickhouse/clickhouse-server
|
||||
docker run -d --name some-clickhouse-server --ulimit nofile=262144:262144 -v /path/to/your/config.xml:/etc/clickhouse-server/config.xml clickhouse/clickhouse-server
|
||||
```
|
||||
|

|
||||
### Start server as a custom user
|
||||
|
||||
```bash
|
||||
# $(pwd)/data/clickhouse should exist and be owned by current user
|
||||
$ docker run --rm --user ${UID}:${GID} --name some-clickhouse-server --ulimit nofile=262144:262144 -v "$(pwd)/logs/clickhouse:/var/log/clickhouse-server" -v "$(pwd)/data/clickhouse:/var/lib/clickhouse" clickhouse/clickhouse-server
|
||||
docker run --rm --user ${UID}:${GID} --name some-clickhouse-server --ulimit nofile=262144:262144 -v "$(pwd)/logs/clickhouse:/var/log/clickhouse-server" -v "$(pwd)/data/clickhouse:/var/lib/clickhouse" clickhouse/clickhouse-server
|
||||
```
|
||||
When you use the image with mounting local directories inside you probably would like to not mess your directory tree with files owner and permissions. Then you could use `--user` argument. In this case, you should mount every necessary directory (`/var/lib/clickhouse` and `/var/log/clickhouse-server`) inside the container. Otherwise, image will complain and not start.
|
||||
|
||||
When you use the image with local directories mounted, you probably want to specify the user to maintain the proper file ownership. Use the `--user` argument and mount `/var/lib/clickhouse` and `/var/log/clickhouse-server` inside the container. Otherwise, the image will complain and not start.
|
||||
|
||||
### Start server from root (useful in case of userns enabled)
|
||||
```
|
||||
$ docker run --rm -e CLICKHOUSE_UID=0 -e CLICKHOUSE_GID=0 --name clickhouse-server-userns -v "$(pwd)/logs/clickhouse:/var/log/clickhouse-server" -v "$(pwd)/data/clickhouse:/var/lib/clickhouse" clickhouse/clickhouse-server
|
||||
|
||||
```bash
|
||||
docker run --rm -e CLICKHOUSE_UID=0 -e CLICKHOUSE_GID=0 --name clickhouse-server-userns -v "$(pwd)/logs/clickhouse:/var/log/clickhouse-server" -v "$(pwd)/data/clickhouse:/var/lib/clickhouse" clickhouse/clickhouse-server
|
||||
```
|
||||
|
||||
### How to create default database and user on starting
|
||||
|
||||
Sometimes you may want to create user (user named `default` is used by default) and database on image starting. You can do it using environment variables `CLICKHOUSE_DB`, `CLICKHOUSE_USER`, `CLICKHOUSE_DEFAULT_ACCESS_MANAGEMENT` and `CLICKHOUSE_PASSWORD`:

## How to extend this image
|
||||
|
||||
If you would like to do additional initialization in an image derived from this one, add one or more `*.sql`, `*.sql.gz`, or `*.sh` scripts under `/docker-entrypoint-initdb.d`. After the entrypoint calls `initdb` it will run any `*.sql` files, run any executable `*.sh` scripts, and source any non-executable `*.sh` scripts found in that directory to do further initialization before starting the service.
|
||||
Also you can provide environment variables `CLICKHOUSE_USER` & `CLICKHOUSE_PASSWORD` that will be used for clickhouse-client during initialization.

|
||||
They are built for stable, prestable and testing releases as long as for every commit to master and for every pull request.
|
||||
|
||||
To find the freshest build from `master`, go to [commits page](https://github.com/ClickHouse/ClickHouse/commits/master), click on the first green check mark or red cross near commit, and click to the “Details” link right after “ClickHouse Build Check”.

|

## Faster builds for development: Split build configuration {#split-build}
|
||||
|
||||
Normally, ClickHouse is statically linked into a single static `clickhouse` binary with minimal dependencies. This is convenient for distribution, but it means that on every change the entire binary needs to be linked, which is slow and may be inconvenient for development. There is an alternative configuration which instead creates dynamically loaded shared libraries and separate binaries `clickhouse-server`, `clickhouse-client` etc., allowing for faster incremental builds. To use it, add the following flags to your `cmake` invocation:
|
||||
```
|
||||
-DUSE_STATIC_LIBRARIES=0 -DSPLIT_SHARED_LIBRARIES=1 -DCLICKHOUSE_SPLIT_BINARY=1
|
||||
```
|
||||
|
||||
Note that the split build has several drawbacks:
|
||||
* There is no single `clickhouse` binary, and you have to run `clickhouse-server`, `clickhouse-client`, etc.
|
||||
* Risk of segfault if you run any of the programs while rebuilding the project.
|
||||
* You cannot run the integration tests since they only work a single complete binary.
|
||||
* You can't easily copy the binaries elsewhere. Instead of moving a single binary you'll need to copy all binaries and libraries.

|
||||
ClickHouse utilizes third-party libraries for different purposes, e.g., to connect to other databases, to decode (encode) data during load (save) from (to) disk or to implement certain specialized SQL functions. To be independent of the available libraries in the target system, each third-party library is imported as a Git submodule into ClickHouse's source tree and compiled and linked with ClickHouse. A list of third-party libraries and their licenses can be obtained by the following query:
|
||||
|
||||
``` sql
|
||||
SELECT library_name, license_type, license_path FROM system.licenses ORDER BY library_name COLLATE 'en';
|
||||
```
|
||||
|
||||
(Note that the listed libraries are the ones located in the `contrib/` directory of the ClickHouse repository. Depending on the build options, some of of the libraries may have not been compiled, and as a result, their functionality may not be available at runtime.
|
||||

||||

The system will prepare ClickHouse binary builds for your pull request individually. To retrieve these builds click the “Details” link next to “ClickHouse build check” entry in the list of checks. There you will find direct links to the built .deb packages of ClickHouse which you can deploy even on your production servers (if you have no fear).
|
||||
|
||||
Most probably some of the builds will fail at first times. This is due to the fact that we check builds both with gcc as well as with clang, with almost all of existing warnings (always with the `-Werror` flag) enabled for clang. On that same page, you can find all of the build logs so that you do not have to build ClickHouse in all of the possible ways.
|
||||
|
||||
## Faster builds for development: Split build configuration {#split-build}
|
||||
|
||||
ClickHouse is normally statically linked into a single static `clickhouse` binary with minimal dependencies. This is convenient for distribution, but it means that for every change the entire binary needs to be re-linked, which is slow and inconvenient for development. As an alternative, you can instead build dynamically linked shared libraries and separate binaries `clickhouse-server`, `clickhouse-client` etc., allowing for faster incremental builds. To use it, add the following flags to your `cmake` invocation:
|
||||
```
|
||||
-DUSE_STATIC_LIBRARIES=0 -DSPLIT_SHARED_LIBRARIES=1 -DCLICKHOUSE_SPLIT_BINARY=1
|
||||
```
|
||||
|
||||
Note that the split build has several drawbacks:
|
||||
* There is no single `clickhouse` binary, and you have to run `clickhouse-server`, `clickhouse-client`, etc.
|
||||
* Risk of segfault if you run any of the programs while rebuilding the project.
|
||||
* You cannot run the integration tests since they only work a single complete binary.
|
||||
* You can't easily copy the binaries elsewhere. Instead of moving a single binary you'll need to copy all binaries and libraries.
|
||||
|
||||
If you are not interested in functionality provided by third-party libraries, you can further speed up the build using `cmake` options
|
||||
```
|
||||
-DENABLE_LIBRARIES=0 -DENABLE_EMBEDDED_COMPILER=0
|
||||
```
|
||||
|
||||
In case of problems with any of the development options, you are on your own!

# NATS Engine {#redisstreams-engine}
|
||||
|
||||
This engine allows integrating ClickHouse with [NATS](https://nats.io/).
|
||||
|
||||
`NATS` lets you:
|
||||
|
||||
- Publish or subcribe to message subjects.
|
||||
- Process new messages as they become available.
|
||||
|
||||
## Creating a Table {#table_engine-redisstreams-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 = NATS SETTINGS
|
||||
nats_url = 'host:port',
|
||||
nats_subjects = 'subject1,subject2,...',
|
||||
nats_format = 'data_format'[,]
|
||||
[nats_row_delimiter = 'delimiter_symbol',]
|
||||
[nats_schema = '',]
|
||||
[nats_num_consumers = N,]
|
||||
[nats_queue_group = 'group_name',]
|
||||
[nats_secure = false,]
|
||||
[nats_max_reconnect = N,]
|
||||
[nats_reconnect_wait = N,]
|
||||
[nats_server_list = 'host1:port1,host2:port2,...',]
|
||||
[nats_skip_broken_messages = N,]
|
||||
[nats_max_block_size = N,]
|
||||
[nats_flush_interval_ms = N,]
|
||||
[nats_username = 'user',]
|
||||
[nats_password = 'password']
|
||||
[redis_password = 'clickhouse']
|
||||
```
|
||||
|
||||
Required parameters:
|
||||
|
||||
- `nats_url` – host:port (for example, `localhost:5672`)..
|
||||
- `nats_subjects` – List of subject for NATS table to subscribe/publsh to. Supports wildcard subjects like `foo.*.bar` or `baz.>`
|
||||
- `nats_format` – Message format. Uses the same notation as the SQL `FORMAT` function, such as `JSONEachRow`. For more information, see the [Formats](../../../interfaces/formats.md) section.
|
||||
|
||||
Optional parameters:
|
||||
|
||||
- `nats_row_delimiter` – Delimiter character, which ends the message.
|
||||
- `nats_schema` – Parameter that must be used if the format requires a schema definition. For example, [Cap’n Proto](https://capnproto.org/) requires the path to the schema file and the name of the root `schema.capnp:Message` object.
|
||||
- `nats_num_consumers` – The number of consumers per table. Default: `1`. Specify more consumers if the throughput of one consumer is insufficient.
|
||||
- `nats_queue_group` – Name for queue group of NATS subscribers. Default is the table name.
|
||||
- `nats_max_reconnect` – Maximum amount of reconnection attempts per try to connect to NATS. Default: `5`.
|
||||
- `nats_reconnect_wait` – Amount of time in milliseconds to sleep between each reconnect attempt. Default: `5000`.
|
||||
- `nats_server_list` - Server list for connection. Can be specified to connect to NATS cluster.
|
||||
- `nats_skip_broken_messages` - NATS message parser tolerance to schema-incompatible messages per block. Default: `0`. If `nats_skip_broken_messages = N` then the engine skips *N* RabbitMQ messages that cannot be parsed (a message equals a row of data).
|
||||
- `nats_max_block_size` - Number of row collected by poll(s) for flushing data from NATS.
|
||||
- `nats_flush_interval_ms` - Timeout for flushing data read from NATS.
|
||||
- `nats_username` - NATS username.
|
||||
- `nats_password` - NATS password.
|
||||
- `nats_token` - NATS auth token.
|
||||
|
||||
SSL connection:
|
||||
|
||||
For secure connection use `nats_secure = 1`.
|
||||
The default behaviour of the used library is not to check if the created TLS connection is sufficiently secure. Whether the certificate is expired, self-signed, missing or invalid: the connection is simply permitted. More strict checking of certificates can possibly be implemented in the future.
|
||||
|
||||
Writing to NATS table:
|
||||
|
||||
If table reads only from one subject, any insert will publish to the same subject.
|
||||
However, if table reads from multiple subjects, we need to specify which subject we want to publish to.
|
||||
That is why whenever inserting into table with multiple subjects, setting `stream_like_engine_insert_queue` is needed.
|
||||
You can select one of the subjects the table reads from and publish your data there. For example:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE queue (
|
||||
key UInt64,
|
||||
value UInt64
|
||||
) ENGINE = NATS
|
||||
SETTINGS nats_url = 'localhost:4444',
|
||||
nats_subjects = 'subject1,subject2',
|
||||
nats_format = 'JSONEachRow';
|
||||
|
||||
INSERT INTO queue
|
||||
SETTINGS stream_like_engine_insert_queue = 'subject2'
|
||||
VALUES (1, 1);
|
||||
```
|
||||
|
||||
Also format settings can be added along with nats-related settings.
|
||||
|
||||
Example:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE queue (
|
||||
key UInt64,
|
||||
value UInt64,
|
||||
date DateTime
|
||||
) ENGINE = NATS
|
||||
SETTINGS nats_url = 'localhost:4444',
|
||||
nats_subjects = 'subject1',
|
||||
nats_format = 'JSONEachRow',
|
||||
date_time_input_format = 'best_effort';
|
||||
```
|
||||
|
||||
The NATS server configuration can be added using the ClickHouse config file.
|
||||
More specifically you can add Redis password for NATS engine:
|
||||
|
||||
``` xml
|
||||
<nats>
|
||||
<user>click</user>
|
||||
<password>house</password>
|
||||
<token>clickhouse</token>
|
||||
</nats>
|
||||
```
|
||||
|
||||
## Description {#description}
|
||||
|
||||
`SELECT` is not particularly useful for reading messages (except for debugging), because each message can be read only once. It is more practical to create real-time threads using [materialized views](../../../sql-reference/statements/create/view.md). To do this:
|
||||
|
||||
1. Use the engine to create a NATS consumer and consider it a data stream.
|
||||
2. Create a table with the desired structure.
|
||||
3. Create a materialized view that converts data from the engine and puts it into a previously created table.
|
||||
|
||||
When the `MATERIALIZED VIEW` joins the engine, it starts collecting data in the background. This allows you to continually receive messages from NATS and convert them to the required format using `SELECT`.
|
||||
One NATS table can have as many materialized views as you like, they do not read data from the table directly, but receive new records (in blocks), this way you can write to several tables with different detail level (with grouping - aggregation and without).
|
||||
|
||||
Example:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE queue (
|
||||
key UInt64,
|
||||
value UInt64
|
||||
) ENGINE = NATS
|
||||
SETTINGS nats_url = 'localhost:4444',
|
||||
nats_subjects = 'subject1',
|
||||
nats_format = 'JSONEachRow',
|
||||
date_time_input_format = 'best_effort';
|
||||
|
||||
CREATE TABLE daily (key UInt64, value UInt64)
|
||||
ENGINE = MergeTree() ORDER BY key;
|
||||
|
||||
CREATE MATERIALIZED VIEW consumer TO daily
|
||||
AS SELECT key, value FROM queue;
|
||||
|
||||
SELECT key, value FROM daily ORDER BY key;
|
||||
```
|
||||
|
||||
To stop receiving streams data or to change the conversion logic, detach the materialized view:
|
||||
|
||||
``` sql
|
||||
DETACH TABLE consumer;
|
||||
ATTACH TABLE consumer;
|
||||
```
|
||||
|
||||
If you want to change the target table by using `ALTER`, we recommend disabling the material view to avoid discrepancies between the target table and the data from the view.

# 我能把 ClickHouse 当做Key-value 键值存储来使用吗？ {#can-i-use-clickhouse-as-a-key-value-storage}.
|
||||
|
||||
简短的回答是 **不能** 。关键值的工作量是在列表中的最高位置时，**不能**{.text-danger}使用ClickHouse的情况。它是一个[OLAP](../../faq/general/olap.md)系统，毕竟有很多优秀的键值存储系统在那里。
|
||||
简短的回答是 **不能** 。键值类型负载是ClickHouse最<span class="text-danger">**不适合**</span>的多种场景之一。ClickHouse 毕竟只是一个[OLAP](../../faq/general/olap.md)系统，对于这类负载来说，目前还是有很多优秀的键值存储系统可供选择。
|
||||
|
||||
然而，可能在某些情况下，使用ClickHouse进行类似键值的查询仍然是有意义的。通常，是一些低预算的产品，主要的工作负载是分析性的，很适合ClickHouse，但也有一些次要的过程需要一个键值模式，请求吞吐量不是很高，没有严格的延迟要求。如果你有无限的预算，你会为这样的次要工作负载安装一个次要的键值数据库，但实际上，多维护一个存储系统（监控、备份等）会有额外的成本，这可能是值得避免的。

如果你决定违背建议，对ClickHouse运行一些类似键值的查询，这里有一些提示。
|
||||
如果你决定不遵从这些建议，想要使用ClickHouse运行一些类似键值的查询，那么这里有一些提示。
|
||||
|
||||
- ClickHouse中点查询昂贵的关键原因是其稀疏的主索引[MergeTree表引擎家族]（../../engines/table-engines/mergetree-family/mergetree.md）。这个索引不能指向每一行具体的数据，相反，它指向每N行，系统必须从邻近的N行扫描到所需的行，沿途读取过多的数据。在一个键值场景中，通过`index_granularity`的设置来减少N的值可能是有用的。
|
||||
- ClickHouse将每一列保存在一组单独的文件中，所以要组装一个完整的行，它需要通过这些文件中的每一个。它们的数量随着列数的增加而线性增加，所以在键值场景中，可能值得避免使用许多列，并将所有的有效数据放在一个单一的`String`列中，并以某种序列化格式（如JSON、Protobuf或任何有效的格式）进行编码。

|
||||
- 还有一种方法，使用[Join](../../engines/table-engines/special/join.md)表引擎代替正常的`MergeTree`表和[joinGet](../../sql-reference/functions/other-functions.md#joinget) 函数来检索数据。它可以提供更好的查询性能，但可能有一些可用性和可靠性问题。下面是一个[使用实例](https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/00800_versatile_storage_join.sql#L49-L51)。
