# 2024 Changelog
### <a id="2410"></a> ClickHouse release 24.10, 2024-10-31
#### Backward Incompatible Change
* Allow to write `SETTINGS` before `FORMAT` in a chain of queries with `UNION` when subqueries are inside parentheses. This closes [#39712](https://github.com/ClickHouse/ClickHouse/issues/39712). Change the behavior when a query has the SETTINGS clause specified twice in a sequence. The closest SETTINGS clause will have a preference for the corresponding subquery. In the previous versions, the outermost SETTINGS clause could take a preference over the inner one. [#68614](https://github.com/ClickHouse/ClickHouse/pull/68614) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Reordering of filter conditions from `[PRE]WHERE` clause is now allowed by default. It could be disabled by setting `allow_reorder_prewhere_conditions` to `false`. [#70657](https://github.com/ClickHouse/ClickHouse/pull/70657) ([Nikita Taranov](https://github.com/nickitat)).
* Remove the `idxd-config` library, which has an incompatible license. This also removes the experimental Intel DeflateQPL codec. [#70987](https://github.com/ClickHouse/ClickHouse/pull/70987) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
#### New Feature
* Allow to grant access to the wildcard prefixes. `GRANT SELECT ON db.table_pefix_* TO user`. [#65311](https://github.com/ClickHouse/ClickHouse/pull/65311) ([pufit](https://github.com/pufit)).
* If you press space bar during query runtime, the client will display a real-time table with detailed metrics. You can enable it globally with the new `--progress-table` option in clickhouse-client; a new `--enable-progress-table-toggle` is associated with the `--progress-table` option, and toggles the rendering of the progress table by pressing the control key (Space). [#63689](https://github.com/ClickHouse/ClickHouse/pull/63689) ([Maria Khristenko](https://github.com/mariaKhr)), [#70423](https://github.com/ClickHouse/ClickHouse/pull/70423) ([Julia Kartseva](https://github.com/jkartseva)).
* Allow to cache read files for object storage table engines and data lakes using hash from ETag + file path as cache key. [#70135](https://github.com/ClickHouse/ClickHouse/pull/70135) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Support creating a table with a query: `CREATE TABLE ... CLONE AS ...`. It clones the source table's schema and then attaches all partitions to the newly created table. This feature is only supported with tables of the `MergeTree` family Closes [#65015](https://github.com/ClickHouse/ClickHouse/issues/65015). [#69091](https://github.com/ClickHouse/ClickHouse/pull/69091) ([tuanpach](https://github.com/tuanpach)).
* Add a new system table, `system.query_metric_log` which contains history of memory and metric values from table system.events for individual queries, periodically flushed to disk. [#66532](https://github.com/ClickHouse/ClickHouse/pull/66532) ([Pablo Marcos](https://github.com/pamarcos)).
* A simple SELECT query can be written with implicit SELECT to enable calculator-style expressions, e.g., `ch "1 + 2"`. This is controlled by a new setting, `implicit_select`. [#68502](https://github.com/ClickHouse/ClickHouse/pull/68502) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Support the `--copy` mode for clickhouse local as a shortcut for format conversion [#68503](https://github.com/ClickHouse/ClickHouse/issues/68503). [#68583](https://github.com/ClickHouse/ClickHouse/pull/68583) ([Denis Hananein](https://github.com/denis-hananein)).
* Add a builtin HTML page for visualizing merges which is available at the `/merges` path. [#70821](https://github.com/ClickHouse/ClickHouse/pull/70821) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add support for `arrayUnion` function. [#68989](https://github.com/ClickHouse/ClickHouse/pull/68989) ([Peter Nguyen](https://github.com/petern48)).
* Allow parametrised SQL aliases. [#50665](https://github.com/ClickHouse/ClickHouse/pull/50665) ([Anton Kozlov](https://github.com/tonickkozlov)).
* A new aggregate function `quantileExactWeightedInterpolated`, which is a interpolated version based on quantileExactWeighted. Some people may wonder why we need a new `quantileExactWeightedInterpolated` since we already have `quantileExactInterpolatedWeighted`. The reason is the new one is more accurate than the old one. This is for spark compatibility. [#69619](https://github.com/ClickHouse/ClickHouse/pull/69619) ([李扬](https://github.com/taiyang-li)).
* A new function `arrayElementOrNull`. It returns `NULL` if the array index is out of range or a Map key not found. [#69646](https://github.com/ClickHouse/ClickHouse/pull/69646) ([李扬](https://github.com/taiyang-li)).
* Allows users to specify regular expressions through new `message_regexp` and `message_regexp_negative` fields in the `config.xml` file to filter out logging. The logging is applied to the formatted un-colored text for the most intuitive developer experience. [#69657](https://github.com/ClickHouse/ClickHouse/pull/69657) ([Peter Nguyen](https://github.com/petern48)).
* Added `RIPEMD160` function, which computes the RIPEMD-160 cryptographic hash of a string. Example: `SELECT HEX(RIPEMD160('The quick brown fox jumps over the lazy dog'))` returns `37F332F68DB77BD9D7EDD4969571AD671CF9DD3B`. [#70087](https://github.com/ClickHouse/ClickHouse/pull/70087) ([Dergousov Maxim](https://github.com/m7kss1)).
* Support reading `Iceberg` tables on `HDFS`. [#70268](https://github.com/ClickHouse/ClickHouse/pull/70268) ([flynn](https://github.com/ucasfl)).
* Support for CTE in the form of `WITH ... INSERT`, as previously we only supported `INSERT ... WITH ...`. [#70593](https://github.com/ClickHouse/ClickHouse/pull/70593) ([Shichao Jin](https://github.com/jsc0218)).
* MongoDB integration: support for all MongoDB types, support for WHERE and ORDER BY statements on MongoDB side, restriction for expressions unsupported by MongoDB. Note that the new inegration is disabled by default, to use it, please set `<use_legacy_mongodb_integration>` to `false` in server config. [#63279](https://github.com/ClickHouse/ClickHouse/pull/63279) ([Kirill Nikiforov](https://github.com/allmazz)).
* A new function `getSettingOrDefault` added to return the default value and avoid exception if a custom setting is not found in the current profile. [#69917](https://github.com/ClickHouse/ClickHouse/pull/69917) ([Shankar](https://github.com/shiyer7474)).
#### Experimental feature
* Refreshable materialized views are production ready. [#70550](https://github.com/ClickHouse/ClickHouse/pull/70550) ([Michael Kolupaev](https://github.com/al13n321)). Refreshable materialized views are now supported in Replicated databases. [#60669](https://github.com/ClickHouse/ClickHouse/pull/60669) ([Michael Kolupaev](https://github.com/al13n321)).
* Parallel replicas are moved from experimental to beta. Reworked settings that control the behavior of parallel replicas algorithms. A quick recap: ClickHouse has four different algorithms for parallel reading involving multiple replicas, which is reflected in the setting `parallel_replicas_mode`, the default value for it is `read_tasks` Additionally, the toggle-switch setting `enable_parallel_replicas` has been added. [#63151](https://github.com/ClickHouse/ClickHouse/pull/63151) ([Alexey Milovidov](https://github.com/alexey-milovidov)), ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Support for the `Dynamic` type in most functions by executing them on internal types inside `Dynamic`. [#69691](https://github.com/ClickHouse/ClickHouse/pull/69691) ([Pavel Kruglov](https://github.com/Avogar)).
* Allow to read/write the `JSON` type as a binary string in `RowBinary` format under settings `input_format_binary_read_json_as_string/output_format_binary_write_json_as_string`. [#70288](https://github.com/ClickHouse/ClickHouse/pull/70288) ([Pavel Kruglov](https://github.com/Avogar)).
* Allow to serialize/deserialize `JSON` column as single String column in the Native format. For output use setting `output_format_native_write_json_as_string`. For input, use serialization version `1` before the column data. [#70312](https://github.com/ClickHouse/ClickHouse/pull/70312) ([Pavel Kruglov](https://github.com/Avogar)).
* Introduced a special (experimental) mode of a merge selector for MergeTree tables which makes it more aggressive for the partitions that are close to the limit by the number of parts. It is controlled by the `merge_selector_use_blurry_base` MergeTree-level setting. [#70645](https://github.com/ClickHouse/ClickHouse/pull/70645) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Implement generic ser/de between Avro's `Union` and ClickHouse's `Variant` types. Resolves [#69713](https://github.com/ClickHouse/ClickHouse/issues/69713). [#69712](https://github.com/ClickHouse/ClickHouse/pull/69712) ([Jiří Kozlovský](https://github.com/jirislav)).
#### Performance Improvement
* Refactor `IDisk` and `IObjectStorage` for better performance. Tables from `plain` and `plain_rewritable` object storages will initialize faster. [#68146](https://github.com/ClickHouse/ClickHouse/pull/68146) ([Alexey Milovidov](https://github.com/alexey-milovidov), [Julia Kartseva](https://github.com/jkartseva)). Do not call the LIST object storage API when determining if a file or directory exists on the plain rewritable disk, as it can be cost-inefficient. [#70852](https://github.com/ClickHouse/ClickHouse/pull/70852) ([Julia Kartseva](https://github.com/jkartseva)). Reduce the number of object storage HEAD API requests in the plain_rewritable disk. [#70915](https://github.com/ClickHouse/ClickHouse/pull/70915) ([Julia Kartseva](https://github.com/jkartseva)).
* Added an ability to parse data directly into sparse columns. [#69828](https://github.com/ClickHouse/ClickHouse/pull/69828) ([Anton Popov](https://github.com/CurtizJ)).
* Improved performance of parsing formats with high number of missed values (e.g. `JSONEachRow`). [#69875](https://github.com/ClickHouse/ClickHouse/pull/69875) ([Anton Popov](https://github.com/CurtizJ)).
* Supports parallel reading of parquet row groups and prefetching of row groups in single-threaded mode. [#69862](https://github.com/ClickHouse/ClickHouse/pull/69862) ([LiuNeng](https://github.com/liuneng1994)).
* Support minmax index for `pointInPolygon`. [#62085](https://github.com/ClickHouse/ClickHouse/pull/62085) ([JackyWoo](https://github.com/JackyWoo)).
* Use bloom filters when reading Parquet files. [#62966](https://github.com/ClickHouse/ClickHouse/pull/62966) ([Arthur Passos](https://github.com/arthurpassos)).
* Lock-free parts rename to avoid INSERT affect SELECT (due to parts lock) (under normal circumstances with `fsync_part_directory`, QPS of SELECT with INSERT in parallel, increased 2x, under heavy load the effect is even bigger). Note, this only includes `ReplicatedMergeTree` for now. [#64955](https://github.com/ClickHouse/ClickHouse/pull/64955) ([Azat Khuzhin](https://github.com/azat)).
* Respect `ttl_only_drop_parts` on `materialize ttl`; only read necessary columns to recalculate TTL and drop parts by replacing them with an empty one. [#65488](https://github.com/ClickHouse/ClickHouse/pull/65488) ([Andrey Zvonov](https://github.com/zvonand)).
* Optimized thread creation in the ThreadPool to minimize lock contention. Thread creation is now performed outside of the critical section to avoid delays in job scheduling and thread management under high load conditions. This leads to a much more responsive ClickHouse under heavy concurrent load. [#68694](https://github.com/ClickHouse/ClickHouse/pull/68694) ([filimonov](https://github.com/filimonov)).
* Enable reading `LowCardinality` string columns from `ORC`. [#69481](https://github.com/ClickHouse/ClickHouse/pull/69481) ([李扬](https://github.com/taiyang-li)).
* Use `LowCardinality` for `ProfileEvents` in system logs such as `part_log`, `query_views_log`, `filesystem_cache_log`. [#70152](https://github.com/ClickHouse/ClickHouse/pull/70152) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Improve performance of `fromUnixTimestamp`/`toUnixTimestamp` functions. [#71042](https://github.com/ClickHouse/ClickHouse/pull/71042) ([kevinyhzou](https://github.com/KevinyhZou)).
* Don't disable nonblocking read from page cache for the entire server when reading from a blocking I/O. This was leading to a poorer performance when a single filesystem (e.g., tmpfs) didn't support the `preadv2` syscall while others do. [#70299](https://github.com/ClickHouse/ClickHouse/pull/70299) ([Antonio Andelic](https://github.com/antonio2368)).
* `ALTER TABLE .. REPLACE PARTITION` doesn't wait anymore for mutations/merges that happen in other partitions. [#59138](https://github.com/ClickHouse/ClickHouse/pull/59138) ([Vasily Nemkov](https://github.com/Enmk)).
* Don't do validation when synchronizing ACL from Keeper. It's validating during creation. It shouldn't matter that much, but there are installations with tens of thousands or even more user created, and the unnecessary hash validation can take a long time to finish during server startup (it synchronizes everything from keeper). [#70644](https://github.com/ClickHouse/ClickHouse/pull/70644) ([Raúl Marín](https://github.com/Algunenano)).
#### Improvement
* `CREATE TABLE AS` will copy `PRIMARY KEY`, `ORDER BY`, and similar clauses (of `MergeTree` tables). [#69739](https://github.com/ClickHouse/ClickHouse/pull/69739) ([sakulali](https://github.com/sakulali)).
* Support 64-bit XID in Keeper. It can be enabled with the `use_xid_64` configuration value. [#69908](https://github.com/ClickHouse/ClickHouse/pull/69908) ([Antonio Andelic](https://github.com/antonio2368)).
* Command-line arguments for Bool settings are set to true when no value is provided for the argument (e.g. `clickhouse-client --optimize_aggregation_in_order --query "SELECT 1"`). [#70459](https://github.com/ClickHouse/ClickHouse/pull/70459) ([davidtsuk](https://github.com/davidtsuk)).
* Added user-level settings `min_free_disk_bytes_to_throw_insert` and `min_free_disk_ratio_to_throw_insert` to prevent insertions on disks that are almost full. [#69755](https://github.com/ClickHouse/ClickHouse/pull/69755) ([Marco Vilas Boas](https://github.com/marco-vb)).
* Embedded documentation for settings will be strictly more detailed and complete than the documentation on the website. This is the first step before making the website documentation always auto-generated from the source code. This has long-standing implications: - it will be guaranteed to have every setting; - there is no chance of having default values obsolete; - we can generate this documentation for each ClickHouse version; - the documentation can be displayed by the server itself even without Internet access. Generate the docs on the website from the source code. [#70289](https://github.com/ClickHouse/ClickHouse/pull/70289) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Allow empty needle in the function `replace`, the same behavior with PostgreSQL. [#69918](https://github.com/ClickHouse/ClickHouse/pull/69918) ([zhanglistar](https://github.com/zhanglistar)).
* Allow empty needle in functions `replaceRegexp*`. [#70053](https://github.com/ClickHouse/ClickHouse/pull/70053) ([zhanglistar](https://github.com/zhanglistar)).
* Symbolic links for tables in the `data/database_name/` directory are created for the actual paths to the table's data, depending on the storage policy, instead of the `store/...` directory on the default disk. [#61777](https://github.com/ClickHouse/ClickHouse/pull/61777) ([Kirill](https://github.com/kirillgarbar)).
* While parsing an `Enum` field from `JSON`, a string containing an integer will be interpreted as the corresponding `Enum` element. This closes [#65119](https://github.com/ClickHouse/ClickHouse/issues/65119). [#66801](https://github.com/ClickHouse/ClickHouse/pull/66801) ([scanhex12](https://github.com/scanhex12)).

/** BFloat16 is a 16-bit floating point type, which has the same number (8) of exponent bits as Float32.
* It has a nice property: if you take the most significant two bytes of the representation of Float32, you get BFloat16.
* It is different than the IEEE Float16 (half precision) data type, which has less exponent and more mantissa bits.
*
* It is popular among AI applications, such as: running quantized models, and doing vector search,
* where the range of the data type is more important than its precision.
*
* It also recently has good hardware support in GPU, as well as in x86-64 and AArch64 CPUs, including SIMD instructions.
* But it is rarely utilized by compilers.
*
* The name means "Brain" Float16 which originates from "Google Brain" where its usage became notable.
* It is also known under the name "bf16". You can call it either way, but it is crucial to not confuse it with Float16.
* Here is a manual implementation of this data type. Only required operations are implemented.
* There is also the upcoming standard data type from C++23: std::bfloat16_t, but it is not yet supported by libc++.
* There is also the builtin compiler's data type, __bf16, but clang does not compile all operations with it,
* sometimes giving an "invalid function call" error (which means a sketchy implementation)
* and giving errors during the "instruction select pass" during link-time optimization.
*
* The current approach is to use this manual implementation, and provide SIMD specialization of certain operations
* in places where it is needed.

# target_compile_definitions(_usearch INTERFACE USEARCH_USE_SIMSIMD)
# ^^ simsimd is not enabled at the moment. Reasons:
# - Vectorization is important for raw scans but not so much for HNSW. We use usearch only for HNSW.
# - Simsimd does compile-time dispatch (choice of SIMD kernels determined by capabilities of the build machine) or dynamic dispatch (SIMD
# kernels chosen at runtime based on cpuid instruction). Since current builds are limited to SSE 4.2 (x86) and NEON (ARM), the speedup of
# the former would be moderate compared to AVX-512 / SVE. The latter is at the moment too fragile with respect to portability across x86
# and ARM machines ... certain conbinations of quantizations / distance functions / SIMD instructions are not implemented at the moment.
# Only x86 for now. On ARM, the linker goes down in flames. To make SimSIMD compile, I had to remove a macro checks in SimSIMD
# for AVX512 (x86, worked nicely) and __ARM_BF16_FORMAT_ALTERNATIVE. It is probably because of that.

For more information and documentation see https://clickhouse.com/.
<!-- This is not related to the docker official library, remove it before commit to https://github.com/docker-library/docs -->
## Versions

### 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. It requires docker version >= `20.10.10` containing [patch](https://github.com/moby/moby/commit/977283509f75303bc6612665a04abf76ff1d2468). As a workaround you could use `docker run --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/.

- The tag `head` is built from the latest commit to the default branch.
- Each tag has optional `-alpine` suffix to reflect that it's built on top of `alpine`.
<!-- REMOVE UNTIL HERE -->
### 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. It requires docker version >= `20.10.10` containing [patch](https://github.com/moby/moby/commit/977283509f75303bc6612665a04abf76ff1d2468). 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
```

# 2024 Changelog
### ClickHouse release v24.10.2.80-stable (96b80057159) FIXME as compared to v24.10.1.2812-stable (9cd0a3738d5)
#### Backward Incompatible Change
* Backported in [#71363](https://github.com/ClickHouse/ClickHouse/issues/71363): Fix possible error `No such file or directory` due to unescaped special symbols in files for JSON subcolumns. [#71182](https://github.com/ClickHouse/ClickHouse/pull/71182) ([Pavel Kruglov](https://github.com/Avogar)).
#### Performance Improvement
* Backported in [#71852](https://github.com/ClickHouse/ClickHouse/issues/71852): Improve the performance and accuracy of system.query_metric_log collection interval by reducing the critical region. [#71473](https://github.com/ClickHouse/ClickHouse/pull/71473) ([Pablo Marcos](https://github.com/pamarcos)).
#### Improvement
* Backported in [#71495](https://github.com/ClickHouse/ClickHouse/issues/71495): Enable `parallel_replicas_local_plan` by default. Building a full-fledged local plan on the query initiator improves parallel replicas performance with less resource consumption, provides opportunities to apply more query optimizations. [#70171](https://github.com/ClickHouse/ClickHouse/pull/70171) ([Igor Nikonov](https://github.com/devcrafter)).
* Backported in [#71985](https://github.com/ClickHouse/ClickHouse/issues/71985): Fixes RIGHT / FULL joins in queries with parallel replicas. Now, RIGHT joins can be executed with parallel replicas (right table reading is distributed). FULL joins can't be parallelized among nodes, - executed locally. [#71162](https://github.com/ClickHouse/ClickHouse/pull/71162) ([Igor Nikonov](https://github.com/devcrafter)).
* Backported in [#71670](https://github.com/ClickHouse/ClickHouse/issues/71670): When user/group is given as ID, the `clickhouse su` fails. This patch fixes it to accept `UID:GID` as well. ### Documentation entry for user-facing changes. [#71626](https://github.com/ClickHouse/ClickHouse/pull/71626) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Backported in [#71940](https://github.com/ClickHouse/ClickHouse/issues/71940): Update `HostResolver` 3 times in a `history` period. [#71863](https://github.com/ClickHouse/ClickHouse/pull/71863) ([Sema Checherinda](https://github.com/CheSema)).
* Backported in [#71922](https://github.com/ClickHouse/ClickHouse/issues/71922): Allow_reorder_prewhere_conditions is on by default with old compatibility settings. [#71867](https://github.com/ClickHouse/ClickHouse/pull/71867) ([Raúl Marín](https://github.com/Algunenano)).
#### Bug Fix (user-visible misbehavior in an official stable release)

## Working with archives
Suppose that we have several archive files with following URIs on S3:
- 'https://s3-us-west-1.amazonaws.com/umbrella-static/top-1m-2018-01-10.csv.zip'
- 'https://s3-us-west-1.amazonaws.com/umbrella-static/top-1m-2018-01-11.csv.zip'
- 'https://s3-us-west-1.amazonaws.com/umbrella-static/top-1m-2018-01-12.csv.zip'
Extracting data from these archives is possible using ::. Globs can be used both in the url part as well as in the part after :: (responsible for the name of a file inside the archive).
``` sql

'https://s3-us-west-1.amazonaws.com/umbrella-static/top-1m-2018-01-1{0..2}.csv.zip :: *.csv'

ClickHouse supports three archive formats:
ZIP
TAR
7Z
While ZIP and TAR archives can be accessed from any supported storage location, 7Z archives can only be read from the local filesystem where ClickHouse is installed.

An alternative way to express which disks are used by a resource is SQL syntax:
```sql
CREATE RESOURCE resource_name (WRITE DISK disk1, READ DISK disk2)
```
Resource could be used for any number of disk for READ or WRITE or both for READ and WRITE. There a syntax allowing to use a resource for all the disks:
```sql
CREATE RESOURCE all_io (READ ANY DISK, WRITE ANY DISK);
```
Note that server configuration options have priority over SQL way to define resources.
## Workload markup {#workload_markup}
Queries can be marked with setting `workload` to distinguish different workloads. If `workload` is not set, than value "default" is used. Note that you are able to specify the other value using settings profiles. Setting constraints can be used to make `workload` constant if you want all queries from the user to be marked with fixed value of `workload` setting.

## Workload hierarchy (SQL only) {#workloads}
Defining resources and classifiers in XML could be challenging. ClickHouse provides SQL syntax that is much more convenient. All resources that were created with `CREATE RESOURCE` share the same structure of the hierarchy, but could differ in some aspects. Every workload created with `CREATE WORKLOAD` maintains a few automatically created scheduling nodes for every resource. A child workload can be created inside another parent workload. Here is the example that defines exactly the same hierarchy as XML configuration above:
```sql
CREATE RESOURCE network_write (WRITE DISK s3)
CREATE RESOURCE network_read (READ DISK s3)
CREATE WORKLOAD all SETTINGS max_requests = 100
CREATE WORKLOAD development IN all
CREATE WORKLOAD production IN all SETTINGS weight = 3
```
The name of a leaf workload without children could be used in query settings `SETTINGS workload = 'name'`. Note that workload classifiers are also created automatically when using SQL syntax.
To customize workload the following settings could be used:
* `priority` - sibling workloads are served according to static priority values (lower value means higher priority).
* `weight` - sibling workloads having the same static priority share resources according to weights.
* `max_requests` - the limit on the number of concurrent resource requests in this workload.
* `max_cost` - the limit on the total inflight bytes count of concurrent resource requests in this workload.
* `max_speed` - the limit on byte processing rate of this workload (the limit is independent for every resource).
* `max_burst` - maximum number of bytes that could be processed by the workload without being throttled (for every resource independently).
Note that workload settings are translated into a proper set of scheduling nodes. For more details, see the description of the scheduling node [types and options](#hierarchy).
There is no way to specify different hierarchies of workloads for different resources. But there is a way to specify different workload setting value for a specific resource:
```sql
CREATE OR REPLACE WORKLOAD all SETTINGS max_requests = 100, max_speed = 1000000 FOR network_read, max_speed = 2000000 FOR network_write
```
Also note that workload or resource could not be dropped if it is referenced from another workload. To update a definition of a workload use `CREATE OR REPLACE WORKLOAD` query.
## Workloads and resources storage {#workload_entity_storage}
Definitions of all workloads and resources in the form of `CREATE WORKLOAD` and `CREATE RESOURCE` queries are stored persistently either on disk at `workload_path` or in ZooKeeper at `workload_zookeeper_path`. ZooKeeper storage is recommended to achieve consistency between nodes. Alternatively `ON CLUSTER` clause could be used along with disk storage.

When a `SELECT` query has the `GROUP BY` clause or at least one aggregate function, ClickHouse (in contrast to MySQL) requires that all expressions in the `SELECT`, `HAVING`, and `ORDER BY` clauses be calculated from keys or from aggregate functions. In other words, each column selected from the table must be used either in keys or inside aggregate functions.

# 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.

## BFloat16
`BFloat16` is a 16-bit floating point data type with 8-bit exponent, sign, and 7-bit mantissa.
It is useful for machine learning and AI applications.
ClickHouse supports conversions between `Float32` and `BFloat16`. Most of other operations are not supported.

# 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`).
