# 2023 Changelog
### ClickHouse release v23.8.4.69-lts (d4d1e7b9ded) FIXME as compared to v23.8.3.48-lts (ebe4eb3d23e)
#### Build/Testing/Packaging Improvement
* Backported in [#55673](https://github.com/ClickHouse/ClickHouse/issues/55673): If the database is already initialized, it doesn't need to be initialized again upon subsequent launches. This can potentially fix the issue of infinite container restarts when the database fails to load within 1000 attempts (relevant for very large databases and multi-node setups). [#50724](https://github.com/ClickHouse/ClickHouse/pull/50724) ([Alexander Nikolaev](https://github.com/AlexNik)).
* Backported in [#55293](https://github.com/ClickHouse/ClickHouse/issues/55293): Resource with source code including submodules is built in Darwin special build task.

* Backported in [#55366](https://github.com/ClickHouse/ClickHouse/issues/55366): Solve issue with launching standalone clickhouse-keeper from clickhouse-server package. [#55226](https://github.com/ClickHouse/ClickHouse/pull/55226) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
* Backported in [#55725](https://github.com/ClickHouse/ClickHouse/issues/55725): Fix integration check python script to use gh api url - Add Readme for CI tests. [#55716](https://github.com/ClickHouse/ClickHouse/pull/55716) ([Max K.](https://github.com/mkaynov)).
#### Bug Fix (user-visible misbehavior in an official stable release)

If the listing of files contains number ranges with leading zeros, use the construction with braces for each digit separately or use `?`.

## Limitations {#limitations}
1. Duplicated rows can be as a result of:
- an exception happens during parsing in the middle of file processing and retries are enabled via `s3queue_loading_retries`;
- `S3Queue` is configured on multiple servers pointing to the same path in zookeeper and keeper session expires before one server managed to commit processed file, which could lead to another server taking processing of the file, which could be partially or fully processed by the first server;
- abnormal server termination.
2. `S3Queue` is configured on multiple servers pointing to the same path in zookeeper and `Ordered` mode is used, then `s3queue_loading_retries` will not work. This will be fixed soon.
## Introspection {#introspection}
For introspection use `system.s3queue` stateless table and `system.s3queue_log` persistent table.
1. `system.s3queue`. This table is not persistent and shows in-memory state of `S3Queue`: which files are currently being processed, which files are processed or failed.

import SelfManaged from '@site/docs/en/_snippets/_self_managed_only_no_roadmap.md';
<SelfManaged />
HTTP server can be used to authenticate ClickHouse users. HTTP authentication can only be used as an external authenticator for existing users, which are defined in `users.xml` or in local access control paths. Currently, [Basic](https://datatracker.ietf.org/doc/html/rfc7617) authentication scheme using GET method is supported.
## HTTP authentication server definition {#http-auth-server-definition}
To define HTTP authentication server you must add `http_authentication_servers` section to the `config.xml`.
**Example**
```xml
<clickhouse>
<!- ... -->
<http_authentication_servers>
<basic_auth_server>
<uri>http://localhost:8000/auth</uri>
<connection_timeout_ms>1000</connection_timeout_ms>
<receive_timeout_ms>1000</receive_timeout_ms>
<send_timeout_ms>1000</send_timeout_ms>
<max_tries>3</max_tries>
<retry_initial_backoff_ms>50</retry_initial_backoff_ms>
<retry_max_backoff_ms>1000</retry_max_backoff_ms>
</basic_auth_server>
</http_authentication_servers>
</clickhouse>
```
Note, that you can define multiple HTTP servers inside the `http_authentication_servers` section using distinct names.
**Parameters**
- `uri` - URI for making authentication request
Timeouts in milliseconds on the socket used for communicating with the server:
- `connection_timeout_ms` - Default: 1000 ms.
- `receive_timeout_ms` - Default: 1000 ms.
- `send_timeout_ms` - Default: 1000 ms.
Retry parameters:
- `max_tries` - The maximum number of attempts to make an authentication request. Default: 3
- `retry_initial_backoff_ms` - The backoff initial interval on retry. Default: 50 ms
- `retry_max_backoff_ms` - The maximum backoff interval. Default: 1000 ms
### Enabling HTTP authentication in `users.xml` {#enabling-http-auth-in-users-xml}
In order to enable HTTP authentication for the user, specify `http_authentication` section instead of `password` or similar sections in the user definition.
Parameters:
- `server` - Name of the HTTP authentication server configured in the main `config.xml` file as described previously.
- `scheme` - HTTP authentication scheme. `Basic` is only supported now. Default: Basic
Example (goes into `users.xml`):
```xml
<clickhouse>
<!- ... -->
<my_user>
<!- ... -->
<http_authentication>
<server>basic_server</server>
<scheme>basic</scheme>
</http_authentication>
</test_user_2>
</clickhouse>
```
:::note
Note that HTTP authentication cannot be used alongside with any other authentication mechanism. The presence of any other sections like `password` alongside `http_authentication` will force ClickHouse to shutdown.
:::
### Enabling HTTP authentication using SQL {#enabling-http-auth-using-sql}
When [SQL-driven Access Control and Account Management](/docs/en/guides/sre/user-management/index.md#access-control) is enabled in ClickHouse, users identified by HTTP authentication can also be created using SQL statements.
```sql
CREATE USER my_user IDENTIFIED WITH HTTP SERVER 'basic_server' SCHEME 'Basic'
```
...or, `Basic` is default without explicit scheme definition
```sql
CREATE USER my_user IDENTIFIED WITH HTTP SERVER 'basic_server'
```
### Passing session settings {#passing-session-settings}
If a response body from HTTP authentication server has JSON format and contains `settings` sub-object, ClickHouse will try parse its key: value pairs as string values and set them as session settings for authenticated user's current session. If parsing is failed, a response body from server will be ignored.

## proxy {#proxy}
Define proxy servers for HTTP and HTTPS requests, currently supported by S3 storage, S3 table functions, and URL functions.
There are three ways to define proxy servers: environment variables, proxy lists, and remote proxy resolvers.
### Environment variables
The `http_proxy` and `https_proxy` environment variables allow you to specify a
proxy server for a given protocol. If you have it set on your system, it should work seamlessly.
This is the simplest approach if a given protocol has
only one proxy server and that proxy server doesn't change.
### Proxy lists
This approach allows you to specify one or more
proxy servers for a protocol. If more than one proxy server is defined,
ClickHouse uses the different proxies on a round-robin basis, balancing the
load across the servers. This is the simplest approach if there is more than
one proxy server for a protocol and the list of proxy servers doesn't change.
### Configuration template
``` xml
<proxy>
<http>
<uri>http://proxy1</uri>
<uri>http://proxy2:3128</uri>
</http>
<https>
<uri>http://proxy1:3128</uri>
</https>
</proxy>
```
`<proxy>` fields
* `<http>` - A list of one or more HTTP proxies
* `<https>` - A list of one or more HTTPS proxies
`<http>` and `<https>` fields
* `<uri>` - The URI of the proxy
### Remote proxy resolvers
It's possible that the proxy servers change dynamically. In that
case, you can define the endpoint of a resolver. ClickHouse sends
an empty GET request to that endpoint, the remote resolver should return the proxy host.
ClickHouse will use it to form the proxy URI using the following template: `{proxy_scheme}://{proxy_host}:{proxy_port}`
### Configuration template
``` xml
<proxy>
<http>
<resolver>
<endpoint>http://resolver:8080/hostname</endpoint>
<proxy_scheme>http</proxy_scheme>
<proxy_port>80</proxy_port>
<proxy_cache_time>10</proxy_cache_time>
</resolver>
</http>
<https>
<resolver>
<endpoint>http://resolver:8080/hostname</endpoint>
<proxy_scheme>http</proxy_scheme>
<proxy_port>3128</proxy_port>
<proxy_cache_time>10</proxy_cache_time>
</resolver>
</https>
</proxy>
```
`<proxy>` fields
* `<http>` - A list of one or more resolvers*
* `<https>` - A list of one or more resolvers*
`<http>` and `<https>` fields
* `<resolver>` - The endpoint and other details for a resolver.
You can have multiple `<resolver>` elements, but only the first
`<resolver>` for a given protocol is used. Any other `<resolver>`
elements for that protocol are ignored. That means load balancing
(if needed) should be implemented by the remote resolver.
`<resolver>` fields
* `<endpoint>` - The URI of the proxy resolver
* `<proxy_scheme>` - The protocol of the final proxy URI. This can be either `http` or `https`.
* `<proxy_port>` - The port number of the proxy resolver
* `<proxy_cache_time>` - The time in seconds that values from the resolver
should be cached by ClickHouse. Setting this value to `0` causes ClickHouse
to contact the resolver for every HTTP or HTTPS request.
### Precedence
Proxy settings are determined in the following order:
1. Remote proxy resolvers
2. Proxy lists
3. Environment variables
ClickHouse will check the highest priority resolver type for the request protocol. If it is not defined,
it will check the next highest priority resolver type, until it reaches the environment resolver.
This also allows a mix of resolver types can be used.

- `enable_bypass_cache_with_threshold` - allows to skip cache completely in case the requested read range exceeds the threshold. Default: `false`. This threshold can be defined by `bypass_cache_threashold`. Default: `268435456` (`256Mi`).
- `do_not_evict_index_and_mark_files` - do not evict small frequently used files according to cache policy. Default: `false`. This setting was added in version 22.8. If you used filesystem cache before this version, then it will not work on versions starting from 22.8 if this setting is set to `true`. If you want to use this setting, clear old cache created before version 22.8 before upgrading.
- `max_file_segment_size` - a maximum size of a single cache file in bytes or in readable format (`ki, Mi, Gi, etc`, example `10Gi`). Default: `8388608` (`8Mi`).

- `load_metadata_threads` - number of threads being used to load cache metadata on starting time. Default: `1`.
File Cache **query/profile settings**:
Some of these settings will disable cache features per query/profile that are enabled by default or in disk configuration settings. For example, you can enable cache in disk configuration and disable it per query/profile setting `enable_filesystem_cache` to `false`. Also setting `cache_on_write_operations` to `true` in disk configuration means that "write-though" cache is enabled. But if you need to disable this general setting per specific queries then setting `enable_filesystem_cache_on_write_operations` to `false` means that write operations cache will be disabled for a specific query/profile.

# largestTriangleThreeBuckets
Applies the [Largest-Triangle-Three-Buckets](https://skemman.is/bitstream/1946/15343/3/SS_MSthesis.pdf) algorithm to the input data.
The algorithm is used for downsampling time series data for visualization. It is designed to operate on series sorted by x coordinate.
It works by dividing the sorted series into buckets and then finding the largest triangle in each bucket. The number of buckets is equal to the number of points in the resulting series.
the function will sort data by `x` and then apply the downsampling algorithm to the sorted data.
**Syntax**
``` sql
