### <a id="227"></a> ClickHouse release 22.7, 2022-07-21
#### Upgrade Notes
* Enable setting `enable_positional_arguments` by default. It allows queries like `SELECT ... ORDER BY 1, 2` where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. [#38204](https://github.com/ClickHouse/ClickHouse/pull/38204) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* `Ordinary` database engine and old storage definition syntax for `*MergeTree` tables are deprecated. By default it's not possible to create new databases with `Ordinary` engine. If `system` database has `Ordinary` engine it will be automatically converted to `Atomic` on server startup. There are settings to keep old behavior (`allow_deprecated_database_ordinary` and `allow_deprecated_syntax_for_merge_tree`), but these settings may be removed in future releases. [#38335](https://github.com/ClickHouse/ClickHouse/pull/38335) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Force rewriting comma join to inner by default (set default value `cross_to_inner_join_rewrite = 2`). To have old behavior set `cross_to_inner_join_rewrite = 1`. [#39326](https://github.com/ClickHouse/ClickHouse/pull/39326) ([Vladimir C](https://github.com/vdimir)). If you will face any incompatibilities, you can turn this setting back.
#### New Feature
* Support expressions with window functions. Closes [#19857](https://github.com/ClickHouse/ClickHouse/issues/19857). [#37848](https://github.com/ClickHouse/ClickHouse/pull/37848) ([Dmitry Novik](https://github.com/novikd)).
* Add new `direct` join algorithm for `EmbeddedRocksDB` tables, see [#33582](https://github.com/ClickHouse/ClickHouse/issues/33582). [#35363](https://github.com/ClickHouse/ClickHouse/pull/35363) ([Vladimir C](https://github.com/vdimir)).
* Added full sorting merge join algorithm. [#35796](https://github.com/ClickHouse/ClickHouse/pull/35796) ([Vladimir C](https://github.com/vdimir)).
* Implement NATS table engine, which allows to pub/sub to NATS. Closes [#32388](https://github.com/ClickHouse/ClickHouse/issues/32388). [#37171](https://github.com/ClickHouse/ClickHouse/pull/37171) ([tchepavel](https://github.com/tchepavel)). ([Kseniia Sumarokova](https://github.com/kssenii))
* Implement table function `mongodb`. Allow writes into `MongoDB` storage / table function. [#37213](https://github.com/ClickHouse/ClickHouse/pull/37213) ([aaapetrenko](https://github.com/aaapetrenko)). ([Kseniia Sumarokova](https://github.com/kssenii))

* Introduced settings `additional_table_filters`. Using this setting, you can specify additional filtering condition for a table which will be applied directly after reading. Example: `select number, x, y from (select number from system.numbers limit 5) f any left join (select x, y from table_1) s on f.number = s.x settings additional_table_filters={'system.numbers : 'number != 3', 'table_1' : 'x != 2'}`. Introduced setting `additional_result_filter` which specifies additional filtering condition for query result. Closes [#37918](https://github.com/ClickHouse/ClickHouse/issues/37918). [#38475](https://github.com/ClickHouse/ClickHouse/pull/38475) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Add `compatibility` setting and `system.settings_changes` system table that contains information about changes in settings through ClickHouse versions.

* Support `parseTimeDelta` function. It can be used like ` ;-+,:` can be used as separators, eg. `1yr-2mo`, `2m:6s`: `SELECT parseTimeDelta('1yr-2mo-4w + 12 days, 3 hours : 1 minute ; 33 seconds')`. [#39071](https://github.com/ClickHouse/ClickHouse/pull/39071) ([jiahui-97](https://github.com/jiahui-97)).
* Added `CREATE TABLE ... EMPTY AS SELECT` query. It automatically deduces table structure from the SELECT query, but does not fill the table after creation. Resolves [#38049](https://github.com/ClickHouse/ClickHouse/issues/38049). [#38272](https://github.com/ClickHouse/ClickHouse/pull/38272) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Added options to limit IO operations with remote storage: `max_remote_read_network_bandwidth_for_server` and `max_remote_write_network_bandwidth_for_server`. [#39095](https://github.com/ClickHouse/ClickHouse/pull/39095) ([Sergei Trifonov](https://github.com/serxa)).
* Add `group_by_use_nulls` setting to make aggregation key columns nullable in the case of ROLLUP, CUBE and GROUPING SETS. Closes [#37359](https://github.com/ClickHouse/ClickHouse/issues/37359). [#38642](https://github.com/ClickHouse/ClickHouse/pull/38642) ([Dmitry Novik](https://github.com/novikd)).
* Add the ability to specify compression level during data export. [#38907](https://github.com/ClickHouse/ClickHouse/pull/38907) ([Nikolay Degterinsky](https://github.com/evillique)).
* Add an option to require explicit grants to SELECT from the `system` database. Details: [#38970](https://github.com/ClickHouse/ClickHouse/pull/38970) ([Vitaly Baranov](https://github.com/vitlibar)).
* Functions `multiMatchAny`, `multiMatchAnyIndex`, `multiMatchAllIndices` and their fuzzy variants now accept non-const pattern array argument.

* Add `send_logs_source_regexp` setting. Send server text logs with specified regexp to match log source name. Empty means all sources. [#39161](https://github.com/ClickHouse/ClickHouse/pull/39161) ([Amos Bird](https://github.com/amosbird)).
* Support `ALTER` for `Hive` tables. [#38214](https://github.com/ClickHouse/ClickHouse/pull/38214) ([lgbo](https://github.com/lgbo-ustc)).
* Support `isNullable` function. This function checks whether it's argument is nullable and return 1 or 0. Closes [#38611](https://github.com/ClickHouse/ClickHouse/issues/38611). [#38841](https://github.com/ClickHouse/ClickHouse/pull/38841) ([lokax](https://github.com/lokax)).
* Added functions for base58 encoding/decoding. [#38159](https://github.com/ClickHouse/ClickHouse/pull/38159) ([Andrey Zvonov](https://github.com/zvonand)).

* Add `clickhouse-diagnostics` binary to the packages. [#38647](https://github.com/ClickHouse/ClickHouse/pull/38647) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
#### Experimental Feature
* Adds new setting `implicit_transaction` to run standalone queries inside a transaction. It handles both creation and closing (via COMMIT if the query succeeded or ROLLBACK if it didn't) of the transaction automatically. [#38344](https://github.com/ClickHouse/ClickHouse/pull/38344) ([Raúl Marín](https://github.com/Algunenano)).
#### Performance Improvement

* `ORDER BY (a, b)` will use all the same benefits as `ORDER BY a, b`. [#38873](https://github.com/ClickHouse/ClickHouse/pull/38873) ([Igor Nikonov](https://github.com/devcrafter)).
* Align branches within a 32B boundary to make benchmark more stable. [#38988](https://github.com/ClickHouse/ClickHouse/pull/38988) ([Guo Wangyang](https://github.com/guowangy)). It improves performance 1..2% on average for Intel.
* Executable UDF, executable dictionaries, and Executable tables will avoid wasting one second during wait for subprocess termination. [#38929](https://github.com/ClickHouse/ClickHouse/pull/38929) ([Constantine Peresypkin](https://github.com/pkit)).
* Optimize accesses to `system.stack_trace` table if not all columns are selected. [#39177](https://github.com/ClickHouse/ClickHouse/pull/39177) ([Azat Khuzhin](https://github.com/azat)).
* Improve isNullable/isConstant/isNull/isNotNull performance for LowCardinality argument. [#39192](https://github.com/ClickHouse/ClickHouse/pull/39192) ([Kruglov Pavel](https://github.com/Avogar)).
* Optimized processing of ORDER BY in window functions. [#34632](https://github.com/ClickHouse/ClickHouse/pull/34632) ([Vladimir Chebotarev](https://github.com/excitoon)).
* The table `system.asynchronous_metric_log` is further optimized for storage space. This closes [#38134](https://github.com/ClickHouse/ClickHouse/issues/38134). See the [YouTube video](https://www.youtube.com/watch?v=0fSp9SF8N8A). [#38428](https://github.com/ClickHouse/ClickHouse/pull/38428) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

* Bugfixes and performance improvements for `parallel_hash` JOIN method. [#37648](https://github.com/ClickHouse/ClickHouse/pull/37648) ([Vladimir C](https://github.com/vdimir)).
* Support hadoop secure RPC transfer (hadoop.rpc.protection=privacy and hadoop.rpc.protection=integrity). [#37852](https://github.com/ClickHouse/ClickHouse/pull/37852) ([Peng Liu](https://github.com/michael1589)).
* Add struct type support in `StorageHive`. [#38118](https://github.com/ClickHouse/ClickHouse/pull/38118) ([lgbo](https://github.com/lgbo-ustc)).
* S3 single objects are now removed with `RemoveObjectRequest`. Implement compatibility with GCP which did not allow to use `removeFileIfExists` effectively breaking approximately half of `remove` functionality. Automatic detection for `DeleteObjects` S3 API, that is not supported by GCS. This will allow to use GCS without explicit `support_batch_delete=0` in configuration. [#37882](https://github.com/ClickHouse/ClickHouse/pull/37882) ([Vladimir Chebotarev](https://github.com/excitoon)).
* Expose basic ClickHouse Keeper related monitoring data (via ProfileEvents and CurrentMetrics). [#38072](https://github.com/ClickHouse/ClickHouse/pull/38072) ([lingpeng0314](https://github.com/lingpeng0314)).

# 2022 Changelog
### ClickHouse release v22.7.1.2484-stable (f4f05ec786a) FIXME as compared to v22.6.1.1985-stable (7000c4e0033)
#### Backward Incompatible Change
* Enable setting `enable_positional_arguments` by default. It allows queries like `SELECT ... ORDER BY 1, 2` where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. [#38204](https://github.com/ClickHouse/ClickHouse/pull/38204) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* `Ordinary` database engine and old storage definition syntax for `*MergeTree` tables are deprecated. By default it's not possible to create new ones. If `system` database has `Ordinary` engine it will be automatically converted to `Atomic` on server startup. There are settings to keep old behavior (`allow_deprecated_database_ordinary` and `allow_deprecated_syntax_for_merge_tree`), but these settings may be removed in future releases. [#38335](https://github.com/ClickHouse/ClickHouse/pull/38335) ([Alexander Tokmakov](https://github.com/tavplubix)).
* * Force rewriting comma join to inner by default (set default value `cross_to_inner_join_rewrite = 2`). To have old behavior set `cross_to_inner_join_rewrite = 1`. [#39326](https://github.com/ClickHouse/ClickHouse/pull/39326) ([Vladimir C](https://github.com/vdimir)).
* Disable format_csv_allow_single_quotes by default. [#37096](https://github.com/ClickHouse/ClickHouse/issues/37096). [#39423](https://github.com/ClickHouse/ClickHouse/pull/39423) ([Kruglov Pavel](https://github.com/Avogar)).
#### New Feature
* Add new `direct` join algorithm for RocksDB, ref [#33582](https://github.com/ClickHouse/ClickHouse/issues/33582). [#35363](https://github.com/ClickHouse/ClickHouse/pull/35363) ([Vladimir C](https://github.com/vdimir)).
* * Added full sorting merge join algorithm. [#35796](https://github.com/ClickHouse/ClickHouse/pull/35796) ([Vladimir C](https://github.com/vdimir)).
* Add a setting `zstd_window_log_max` to configure max memory usage on zstd decoding when importing external files. Closes [#35693](https://github.com/ClickHouse/ClickHouse/issues/35693). [#37015](https://github.com/ClickHouse/ClickHouse/pull/37015) ([wuxiaobai24](https://github.com/wuxiaobai24)).
* Implement NatsStorage - table engine, which allows to pub/sub to NATS. Closes [#32388](https://github.com/ClickHouse/ClickHouse/issues/32388). [#37171](https://github.com/ClickHouse/ClickHouse/pull/37171) ([tchepavel](https://github.com/tchepavel)).
* Implement table function MongoDB. Allow writes into MongoDB storage / table function. [#37213](https://github.com/ClickHouse/ClickHouse/pull/37213) ([aaapetrenko](https://github.com/aaapetrenko)).
* `clickhouse-keeper` new feature: add support for real-time digest calculation and verification. [#37555](https://github.com/ClickHouse/ClickHouse/pull/37555) ([Antonio Andelic](https://github.com/antonio2368)).
* In [#17202](https://github.com/ClickHouse/ClickHouse/issues/17202) was reported that host_regexp was being tested against only one of the possible PTR responses. This PR makes the necessary changes so that host_regexp is applied against all possible PTR responses and validate if any matches. [#37827](https://github.com/ClickHouse/ClickHouse/pull/37827) ([Arthur Passos](https://github.com/arthurpassos)).
* Support hadoop secure rpc transfer(hadoop.rpc.protection=privacy and hadoop.rpc.protection=integrity). [#37852](https://github.com/ClickHouse/ClickHouse/pull/37852) ([Peng Liu](https://github.com/michael1589)).
* Add struct type support in `StorageHive`. [#38118](https://github.com/ClickHouse/ClickHouse/pull/38118) ([lgbo](https://github.com/lgbo-ustc)).
* Added Base58 encoding/decoding. [#38159](https://github.com/ClickHouse/ClickHouse/pull/38159) ([Andrey Zvonov](https://github.com/zvonand)).
* Add chart visualization to Play UI. [#38197](https://github.com/ClickHouse/ClickHouse/pull/38197) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* support `alter` command on `StorageHive` table. [#38214](https://github.com/ClickHouse/ClickHouse/pull/38214) ([lgbo](https://github.com/lgbo-ustc)).
* Added `CREATE TABLE ... EMPTY AS SELECT` query. It automatically deduces table structure from the SELECT query, but does not fill the table after creation. Resolves [#38049](https://github.com/ClickHouse/ClickHouse/issues/38049). [#38272](https://github.com/ClickHouse/ClickHouse/pull/38272) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Adds new setting `implicit_transaction` to run standalone queries inside a transaction. It handles both creation and closing (via COMMIT if the query succeeded or ROLLBACK if it didn't) of the transaction automatically. [#38344](https://github.com/ClickHouse/ClickHouse/pull/38344) ([Raúl Marín](https://github.com/Algunenano)).
* Allow trailing comma in columns list. closes [#38425](https://github.com/ClickHouse/ClickHouse/issues/38425). [#38440](https://github.com/ClickHouse/ClickHouse/pull/38440) ([chen](https://github.com/xiedeyantu)).
* Compress clickhouse into self-extracting executable (path programs/self-extracting). New build target 'self-extracting' is added. [#38447](https://github.com/ClickHouse/ClickHouse/pull/38447) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Introduced settings `additional_table_filters`. Using this setting, you can specify additional filtering condition for a table which will be applied directly after reading. Example: `select number, x, y from (select number from system.numbers limit 5) f any left join (select x, y from table_1) s on f.number = s.x settings additional_table_filters={'system.numbers : 'number != 3', 'table_1' : 'x != 2'}`. Introduced setting `additional_result_filter` which specifies additional filtering condition for query result. Closes [#37918](https://github.com/ClickHouse/ClickHouse/issues/37918). [#38475](https://github.com/ClickHouse/ClickHouse/pull/38475) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Add SQLInsert output format. Closes [#38441](https://github.com/ClickHouse/ClickHouse/issues/38441). [#38477](https://github.com/ClickHouse/ClickHouse/pull/38477) ([Kruglov Pavel](https://github.com/Avogar)).
* Downloadable clickhouse executable is compressed self-extracting. [#38653](https://github.com/ClickHouse/ClickHouse/pull/38653) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Support `isNullable` function. This function checks whether it's argument is nullable and return true(1) or false(0). Closes [#38611](https://github.com/ClickHouse/ClickHouse/issues/38611). [#38841](https://github.com/ClickHouse/ClickHouse/pull/38841) ([lokax](https://github.com/lokax)).
* Add functions `translate(string, from_string, to_string)` and `translateUTF8(string, from_string, to_string)`. [#38935](https://github.com/ClickHouse/ClickHouse/pull/38935) ([Nikolay Degterinsky](https://github.com/evillique)).
* Add `compatibility` setting and `system.settings_changes` system table that contains information about changes in settings through ClickHouse versions. Closes [#35972](https://github.com/ClickHouse/ClickHouse/issues/35972). [#38957](https://github.com/ClickHouse/ClickHouse/pull/38957) ([Kruglov Pavel](https://github.com/Avogar)).
* Add the 3rd parameter to the tupleElement function and return it if tuple doesn't have a member. Only works if the 2nd parameter is of type String. Closes [#38872](https://github.com/ClickHouse/ClickHouse/issues/38872). [#38989](https://github.com/ClickHouse/ClickHouse/pull/38989) ([lokax](https://github.com/lokax)).
* Support parseTimedelta function. It can be used like ```sql # ' ', ';', '-', '+', ',', ':' can be used as separators, eg. "1yr-2mo", "2m:6s" SELECT parseTimeDelta('1yr-2mo-4w + 12 days, 3 hours : 1 minute ; 33 seconds');. [#39071](https://github.com/ClickHouse/ClickHouse/pull/39071) ([jiahui-97](https://github.com/jiahui-97)).
* Added options to limit IO operations with remote storage: `max_remote_read_network_bandwidth_for_server` and `max_remote_write_network_bandwidth_for_server`. [#39095](https://github.com/ClickHouse/ClickHouse/pull/39095) ([Sergei Trifonov](https://github.com/serxa)).
* Add `send_logs_source_regexp` setting. Send server text logs with specified regexp to match log source name. Empty means all sources. [#39161](https://github.com/ClickHouse/ClickHouse/pull/39161) ([Amos Bird](https://github.com/amosbird)).

* A less efficient execution plan can be generated for query with ORDER BY (a, b) than for ORDER BY a, b. [#38873](https://github.com/ClickHouse/ClickHouse/pull/38873) ([Igor Nikonov](https://github.com/devcrafter)).
* Executable UDF, Executable Dictionary, Executable Storage poll subprocess fix 1 second subprocess wait during subprocess termination. [#38929](https://github.com/ClickHouse/ClickHouse/pull/38929) ([Constantine Peresypkin](https://github.com/pkit)).
* * Pushdown filter to the right side of sorting join. [#39123](https://github.com/ClickHouse/ClickHouse/pull/39123) ([Vladimir C](https://github.com/vdimir)).
* Optimize accesses to system.stack_trace. [#39177](https://github.com/ClickHouse/ClickHouse/pull/39177) ([Azat Khuzhin](https://github.com/azat)).

* S3 single objects are now removed with `RemoveObjectRequest` (sic). Fixed a bug with `S3ObjectStorage` on GCP which did not allow to use `removeFileIfExists` effectively breaking approximately half of `remove` functionality. Automatic detection for `DeleteObjects` S3 API, that is not supported by GCS. This will allow to use GCS without explicit `support_batch_delete=0` in configuration. [#37882](https://github.com/ClickHouse/ClickHouse/pull/37882) ([Vladimir Chebotarev](https://github.com/excitoon)).

## How ClickHouse documentation is generated? {#how-clickhouse-documentation-is-generated}
## Generating ClickHouse documentation {#how-clickhouse-documentation-is-generated}
ClickHouse documentation is built using [build.py](build.py) script that uses [mkdocs](https://www.mkdocs.org) library and it’s dependencies to separately build all version of documentations (all languages in either single and multi page mode) as static HTMLs for each single page version. The results are then put in the correct directory structure. It is recommended to use Python 3.7 to run this script.
ClickHouse documentation is built using [Docusaurus](https://docusaurus.io).
[release.sh](release.sh) also pulls static files needed for [official ClickHouse website](https://clickhouse.com) from [../../website](../../website) folder then pushes to specified GitHub repo to be served via [GitHub Pages](https://pages.github.com).
## Check the look of your documentation changes {#how-to-check-if-the-documentation-will-look-fine}
## How to check if the documentation will look fine? {#how-to-check-if-the-documentation-will-look-fine}
There are a few options that are all useful depending on how large or complex your edits are.
There are few options that are all useful depending on how large or complex your edits are.
### Use the GitHub web interface to edit
### Use GitHub web interface to edit
Every page in the docs has an **Edit this page** link that opens the page in the GitHub editor. GitHub has Markdown support with a preview feature. The details of GitHub Markdown and the documentation Markdown are a bit different but generally this is close enough, and the person merging your PR will build the docs and check them.
GitHub has Markdown support with preview feature, but the details of GitHub Markdown dialect are a bit different in ClickHouse documentation.
### Install a Markdown editor or plugin for your IDE {#install-markdown-editor-or-plugin-for-your-ide}
### Install Markdown editor or plugin for your IDE {#install-markdown-editor-or-plugin-for-your-ide}
Usually, these plugins provide a preview of how the markdown will render, and they catch basic errors like unclosed tags very early.
Usually those also have some way to preview how Markdown will look like, which allows to catch basic errors like unclosed tags very early.
### Use build.py {#use-build-py}
## Build the docs locally {#use-build-py}
It’ll take some effort to go through, but the result will be very close to production documentation.
You can build the docs locally. It takes a few minutes to set up, but once you have done it the first time, the process is very simple.
For the first time you’ll need to:
### Clone the repos
#### 1. Set up virtualenv
The documentation is in two repos, clone both of them:
- [ClickHouse/ClickHouse](https://github.com/ClickHouse/ClickHouse)
- [ClickHouse/ClickHouse-docs](https://github.com/ClickHouse/clickhouse-docs)
``` bash
$ cd ClickHouse/docs/tools
$ mkdir venv
$ virtualenv -p $(which python3) venv
$ source venv/bin/activate
$ pip3 install -r requirements.txt
### Install Node.js
The documentation is built with Docusaurus, which requires Node.js. We recommend version 16. Install [Node.js](https://nodejs.org/en/download/).
### Copy files into place
Docusaurus expects all of the markdown files to be located in the directory tree `clickhouse-docs/docs/`. This is not the way our repos are set up, so some copying of files is needed to build the docs:
```bash
# from the parent directory of both the ClickHouse/ClickHouse and ClickHouse-clickhouse-docs repos:
cp -r ClickHouse/docs/en/development clickhouse-docs/docs/en/
cp -r ClickHouse/docs/en/engines clickhouse-docs/docs/en/
cp -r ClickHouse/docs/en/getting-started clickhouse-docs/docs/en/
cp -r ClickHouse/docs/en/interfaces clickhouse-docs/docs/en/
cp -r ClickHouse/docs/en/operations clickhouse-docs/docs/en/
cp -r ClickHouse/docs/en/sql-reference clickhouse-docs/docs/en/
cp -r ClickHouse/docs/ru/* clickhouse-docs/docs/ru/
cp -r ClickHouse/docs/zh clickhouse-docs/docs/
```
#### 2. Run build.py
#### Note: Symlinks will not work.
### Setup Docusaurus
When all prerequisites are installed, running `build.py` without args (there are some, check `build.py --help`) will generate `ClickHouse/docs/build` folder with complete static html website.
There are two commands that you may need to use with Docusaurus:
- `yarn install`
- `yarn start`
The easiest way to see the result is to use `--livereload=8888` argument of build.py. Alternatively, you can manually launch a HTTP server to serve the docs, for example by running `cd ClickHouse/docs/build && python3 -m http.server 8888`. Then go to http://localhost:8888 in browser. Feel free to use any other port instead of 8888.
#### Install Docusaurus and its dependencies:
```bash
cd clickhouse-docs
yarn install
```
#### Start a development Docusaurus environment
This command will start Docusaurus in development mode, which means that as you edit source (for example, `.md` files) files the changes will be rendered into HTML files and served by the Docusaurus development server.
```bash
yarn start
```
### Make your changes to the markdown files
Edit your files. Remember that if you are editing files in the `ClickHouse/ClickHouse` repo then you should edit them
in that repo and then copy the edited file into the `ClickHouse/clickhouse-docs/` directory structure so that they are updated in your develoment environment.
`yarn start` probably opened a browser for you when you ran it; if not, open a browser to `http://localhost:3000/docs/en/intro` and navigate to the documentation that you are changing. If you have already made the changes, you can verify them here; if not, make them, and you will see the page update as you save the changes.
## How to change code highlighting? {#how-to-change-code-hl}
ClickHouse does not use mkdocs `highlightjs` feature. It uses modified pygments styles instead.
If you want to change code highlighting, edit the `website/css/highlight.css` file.
Currently, an [eighties](https://github.com/idleberg/base16-pygments/blob/master/css/base16-eighties.dark.css) theme
is used.
Code highlighting is based on the language chosen for your code blocks. Specify the language when you start the code block:
<pre lang="no-highlight"><code>```sql
SELECT firstname from imdb.actors;
```
</code></pre>
```sql
SELECT firstname from imdb.actors;
```
If you need a language supported then open an issue in [ClickHouse-docs](https://github.com/ClickHouse/clickhouse-docs/issues).

At the moment there’s no easy way to do just that, but you can consider:
