### Compatibility
- The amd64 image requires support for [SSE3 instructions](https://en.wikipedia.org/wiki/SSE3). Virtually all x86 CPUs after 2005 support SSE3.
- The arm64 image requires support for the [ARMv8.2-A architecture](https://en.wikipedia.org/wiki/AArch64#ARMv8.2-A) and additionally the Load-Acquire RCpc register. The register is optional in version ARMv8.2-A and mandatory in [ARMv8.3-A](https://en.wikipedia.org/wiki/AArch64#ARMv8.3-A). Supported in Graviton >=2, Azure and GCP instances. Examples for unsupported devices are Raspberry Pi 4 (ARMv8.0-A) and Jetson AGX Xavier/Orin (ARMv8.2-A).
- Since the Clickhouse 24.11 Ubuntu images started using `ubuntu:22.04` as its base image.

As a workaround you could use `docker run [--privileged | --security-opt seccomp=unconfined]` instead, however that has security implications.

# ClickHouse Server Docker Image
## What is ClickHouse?
%%LOGO%%
ClickHouse is an open-source column-oriented DBMS (columnar database management system) for online analytical processing (OLAP) that allows users to generate analytical reports using SQL queries in real-time.
ClickHouse works 100-1000x faster than traditional database management systems, and processes hundreds of millions to over a billion rows and tens of gigabytes of data per server per second. With a widespread user base around the globe, the technology has received praise for its reliability, ease of use, and fault tolerance.
For more information and documentation see https://clickhouse.com/.

As a workaround you could use `docker run --security-opt seccomp=unconfined` instead, however that has security implications.
## How to use this image
### start server instance
```bash
docker run -d --name some-clickhouse-server --ulimit nofile=262144:262144 %%IMAGE%%
```
By default, ClickHouse will be accessible only via the Docker network. See the **networking** section below.
By default, starting above server instance will be run as the `default` user without password.
### connect to it from a native client
```bash
docker run -it --rm --link some-clickhouse-server:clickhouse-server --entrypoint clickhouse-client %%IMAGE%% --host clickhouse-server
# OR
docker exec -it some-clickhouse-server clickhouse-client
```
More information about the [ClickHouse client](https://clickhouse.com/docs/en/interfaces/cli/).
### connect to it using curl
```bash
echo "SELECT 'Hello, ClickHouse!'" | docker run -i --rm --link some-clickhouse-server:clickhouse-server buildpack-deps:curl curl 'http://clickhouse-server:8123/?query=' -s --data-binary @-
```
More information about the [ClickHouse HTTP Interface](https://clickhouse.com/docs/en/interfaces/http/).
### stopping / removing the container
```bash
docker stop some-clickhouse-server
docker rm some-clickhouse-server
```
### networking
You can expose your ClickHouse running in docker by [mapping a particular port](https://docs.docker.com/config/containers/container-networking/) from inside the container using host ports:
```bash
docker run -d -p 18123:8123 -p19000:9000 --name some-clickhouse-server --ulimit nofile=262144:262144 %%IMAGE%%
echo 'SELECT version()' | curl 'http://localhost:18123/' --data-binary @-
```
`22.6.3.35`
Or by allowing the container to use [host ports directly](https://docs.docker.com/network/host/) using `--network=host` (also allows achieving better network performance):
```bash
docker run -d --network=host --name some-clickhouse-server --ulimit nofile=262144:262144 %%IMAGE%%
echo 'SELECT version()' | curl 'http://localhost:8123/' --data-binary @-
```
`22.6.3.35`
### Volumes
Typically you may want to mount the following folders inside your container to achieve persistency:
- `/var/lib/clickhouse/` - main folder where ClickHouse stores the data
- `/var/log/clickhouse-server/` - logs
```bash
docker run -d \
-v "$PWD/ch_data:/var/lib/clickhouse/" \
-v "$PWD/ch_logs:/var/log/clickhouse-server/" \
--name some-clickhouse-server --ulimit nofile=262144:262144 %%IMAGE%%
```
You may also want to mount:
- `/etc/clickhouse-server/config.d/*.xml` - files with server configuration adjustments
- `/etc/clickhouse-server/users.d/*.xml` - files with user settings adjustments
- `/docker-entrypoint-initdb.d/` - folder with database initialization scripts (see below).
### Linux capabilities
ClickHouse has some advanced functionality, which requires enabling several [Linux capabilities](https://man7.org/linux/man-pages/man7/capabilities.7.html).
They are optional and can be enabled using the following [docker command-line arguments](https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities):
```bash
docker run -d \
--cap-add=SYS_NICE --cap-add=NET_ADMIN --cap-add=IPC_LOCK \
--name some-clickhouse-server --ulimit nofile=262144:262144 %%IMAGE%%
```
Read more in [knowledge base](https://clickhouse.com/docs/knowledgebase/configure_cap_ipc_lock_and_cap_sys_nice_in_docker).
## Configuration
The container exposes port 8123 for the [HTTP interface](https://clickhouse.com/docs/en/interfaces/http_interface/) and port 9000 for the [native client](https://clickhouse.com/docs/en/interfaces/tcp/).
ClickHouse configuration is represented with a file "config.xml" ([documentation](https://clickhouse.com/docs/en/operations/configuration_files/))
### 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 %%IMAGE%%
```
### Start server as 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 "$PWD/data/clickhouse:/var/lib/clickhouse" %%IMAGE%%
```
When you use the image with local directories mounted, you probably want to specify the user to maintain the proper file ownership. Use the `--user` argument and mount `/var/lib/clickhouse` and `/var/log/clickhouse-server` inside the container. Otherwise, the image will complain and not start.
### Start server from root (useful in case of enabled user namespace)
```bash
docker run --rm -e CLICKHOUSE_RUN_AS_ROOT=1 --name clickhouse-server-userns -v "$PWD/logs/clickhouse:/var/log/clickhouse-server" -v "$PWD/data/clickhouse:/var/lib/clickhouse" %%IMAGE%%
```
### How to create default database and user on starting
Sometimes you may want to create a user (user named `default` is used by default) and database on a container start. You can do it using environment variables `CLICKHOUSE_DB`, `CLICKHOUSE_USER`, `CLICKHOUSE_DEFAULT_ACCESS_MANAGEMENT` and `CLICKHOUSE_PASSWORD`:
```bash
docker run --rm -e CLICKHOUSE_DB=my_database -e CLICKHOUSE_USER=username -e CLICKHOUSE_DEFAULT_ACCESS_MANAGEMENT=1 -e CLICKHOUSE_PASSWORD=password -p 9000:9000/tcp %%IMAGE%%
```
## How to extend this image
To perform 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.
For example, to add an additional user and database, add the following to `/docker-entrypoint-initdb.d/init-db.sh`:
```bash
#!/bin/bash
set -e
clickhouse client -n <<-EOSQL
CREATE DATABASE docker;
CREATE TABLE docker.docker (x Int32) ENGINE = Log;
EOSQL
```

cache evicts entries "lazily", i.e. when an entry becomes stale, it is not immediately removed from the cache. Instead, when a new entry

Sets the number of threads performing background merges and mutations for tables with MergeTree engines. You can only increase the number of threads at runtime. To lower the number of threads you have to restart the server. By adjusting this setting, you manage CPU and disk load. Smaller pool size utilizes less CPU and disk resources, but background processes advance slower which might eventually impact query performance.
Before changing it, please also take a look at related MergeTree settings, such as `number_of_free_entries_in_pool_to_lower_max_size_of_merge` and `number_of_free_entries_in_pool_to_execute_mutation`.

# AggregateFunction
Aggregate functions can have an implementation-defined intermediate state that can be serialized to an `AggregateFunction(...)` data type and stored in a table, usually, by means of [a materialized view](../../sql-reference/statements/create/view.md). The common way to produce an aggregate function state is by calling the aggregate function with the `-State` suffix. To get the final result of aggregation in the future, you must use the same aggregate function with the `-Merge`suffix.

# Data Types in ClickHouse
ClickHouse can store various kinds of data in table cells. This section describes the supported data types and special considerations for using and/or implementing them if any.
This section describes the data types supported by ClickHouse, for example [integers](int-uint.md), [floats](float.md) and [strings](string.md).
:::note
You can check whether a data type name is case-sensitive in the [system.data_type_families](../../operations/system-tables/data_type_families.md#system_tables-data_type_families) table.
:::
ClickHouse data types include:
- **Integer types**: [signed and unsigned integers](./int-uint.md) (`UInt8`, `UInt16`, `UInt32`, `UInt64`, `UInt128`, `UInt256`, `Int8`, `Int16`, `Int32`, `Int64`, `Int128`, `Int256`)
- **Floating-point numbers**: [floats](./float.md)(`Float32` and `Float64`) and [`Decimal` values](./decimal.md)
- **Boolean**: ClickHouse has a [`Boolean` type](./boolean.md)
- **Strings**: [`String`](./string.md) and [`FixedString`](./fixedstring.md)
- **Dates**: use [`Date`](./date.md) and [`Date32`](./date32.md) for days, and [`DateTime`](./datetime.md) and [`DateTime64`](./datetime64.md) for instances in time
- **Object**: the [`Object`](./json.md) stores a JSON document in a single column (deprecated)
- **JSON**: the [`JSON` object](./newjson.md) stores a JSON document in a single column
- **UUID**: a performant option for storing [`UUID` values](./uuid.md)
- **Low cardinality types**: use an [`Enum`](./enum.md) when you have a handful of unique values, or use [`LowCardinality`](./lowcardinality.md) when you have up to 10,000 unique values of a column
- **Arrays**: any column can be defined as an [`Array` of values](./array.md)
- **Maps**: use [`Map`](./map.md) for storing key/value pairs
- **Aggregation function types**: use [`SimpleAggregateFunction`](./simpleaggregatefunction.md) and [`AggregateFunction`](./aggregatefunction.md) for storing the intermediate status of aggregate function results
- **Nested data structures**: A [`Nested` data structure](./nested-data-structures/index.md) is like a table inside a cell
- **Tuples**: A [`Tuple` of elements](./tuple.md), each having an individual type.
- **Nullable**: [`Nullable`](./nullable.md) allows you to store a value as `NULL` when a value is "missing" (instead of the column settings its default value for the data type)
- **IP addresses**: use [`IPv4`](./ipv4.md) and [`IPv6`](./ipv6.md) to efficiently store IP addresses
- **Geo types**: for [geographical data](./geo.md), including `Point`, `Ring`, `Polygon` and `MultiPolygon`
- **Special data types**: including [`Expression`](./special-data-types/expression.md), [`Set`](./special-data-types/set.md), [`Nothing`](./special-data-types/nothing.md) and [`Interval`](./special-data-types/interval.md)
System table [system.data_type_families](../../operations/system-tables/data_type_families.md#system_tables-data_type_families) provides an
overview of all available data types.
It also shows whether a data type is an alias to another data type and its name is case-sensitive (e.g. `bool` vs. `BOOL`).

## ALTER MODIFY COLUMN to JSON type
It's possible to alter an existing table and change the type of the column to the new `JSON` type. Right now only alter from `String` type is supported.
**Example**
```sql
CREATE TABLE test (json String) ENGINE=MergeTree ORDeR BY tuple();
INSERT INTO test VALUES ('{"a" : 42}'), ('{"a" : 43, "b" : "Hello"}'), ('{"a" : 44, "b" : [1, 2, 3]}')), ('{"c" : "2020-01-01"}');
ALTER TABLE test MODIFY COLUMN json JSON;
SELECT json, json.a, json.b, json.c FROM test;
```
```text
┌─json─────────────────────────┬─json.a─┬─json.b──┬─json.c─────┐

# SimpleAggregateFunction
`SimpleAggregateFunction(name, types_of_arguments...)` data type stores current value of the aggregate function, and does not store its full state as [`AggregateFunction`](../../sql-reference/data-types/aggregatefunction.md) does. This optimization can be applied to functions for which the following property holds: the result of applying a function `f` to a row set `S1 UNION ALL S2` can be obtained by applying `f` to parts of the row set separately, and then again applying `f` to the results: `f(S1 UNION ALL S2) = f(f(S1) UNION ALL f(S2))`. This property guarantees that partial aggregation results are enough to compute the combined one, so we do not have to store and process any extra data.
