# 2024 Changelog
### ClickHouse release v24.6.2.17-stable (5710a8b5c0c) FIXME as compared to v24.6.1.4423-stable (dcced7c8478)
#### New Feature
* Backported in [#66002](https://github.com/ClickHouse/ClickHouse/issues/66002): Add AzureQueue storage. [#65458](https://github.com/ClickHouse/ClickHouse/pull/65458) ([Kseniia Sumarokova](https://github.com/kssenii)).

#### Bug Fix (user-visible misbehavior in an official stable release)
* Backported in [#65935](https://github.com/ClickHouse/ClickHouse/issues/65935): For queries that read from `PostgreSQL`, cancel the internal `PostgreSQL` query if the ClickHouse query is finished.

# Startup Scripts
ClickHouse can run arbitrary SQL queries from the server configuration during startup. This can be useful for migrations or automatic schema creation.
```xml
<clickhouse>
<startup_scripts>
<scripts>
<query>CREATE ROLE OR REPLACE test_role</query>
</scripts>
<scripts>
<query>CREATE TABLE TestTable (id UInt64) ENGINE=TinyLog</query>
<condition>SELECT 1;</condition>
</scripts>
</startup_scripts>
</clickhouse>
```
ClickHouse executes all queries from the `startup_scripts` sequentially in the specified order. If any of the queries fail, the execution of the following queries won't be interrupted.
You can specify a conditional query in the config. In that case, the corresponding query executes only when the condition query returns the value `1` or `true`.
:::note
If the condition query returns any other value than `1` or `true`, the result will be interpreted as `false`, and the corresponding won't be executed.

# clickhouse-disks
# Clickhouse-disks
A utility providing filesystem-like operations for ClickHouse disks.
A utility providing filesystem-like operations for ClickHouse disks. It can work in both interactive and not interactive modes.
Program-wide options:
## Program-wide options
* `--config-file, -C` -- path to ClickHouse config, defaults to `/etc/clickhouse-server/config.xml`.
* `--save-logs` -- Log progress of invoked commands to `/var/log/clickhouse-server/clickhouse-disks.log`.
* `--log-level` -- What [type](../server-configuration-parameters/settings#server_configuration_parameters-logger) of events to log, defaults to `none`.
* `--disk` -- what disk to use for `mkdir, move, read, write, remove` commands. Defaults to `default`.
* `--query, -q` -- single query that can be executed without launching interactive mode
* `--help, -h` -- print all the options and commands with description
## Default Disks
After the launch two disks are initialized. The first one is a disk `local` that is supposed to imitate local file system from which clickhouse-disks utility was launched. The second one is a disk `default` that is mounted to the local filesystem in the directory that can be found in config as a parameter `clickhouse/path` (default value is `/var/lib/clickhouse`).
## Clickhouse-disks state
For each disk that was added the utility stores current directory (as in a usual filesystem). User can change current directory and switch between disks.
State is reflected in a prompt "`disk_name`:`path_name`"
## Commands
* `copy [--disk-from d1] [--disk-to d2] <FROM_PATH> <TO_PATH>`.
Recursively copy data from `FROM_PATH` at disk `d1` (defaults to `disk` value if not provided)
to `TO_PATH` at disk `d2` (defaults to `disk` value if not provided).
* `move <FROM_PATH> <TO_PATH>`.
Move file or directory from `FROM_PATH` to `TO_PATH`.
* `remove <PATH>`.
Remove `PATH` recursively.
* `link <FROM_PATH> <TO_PATH>`.
Create a hardlink from `FROM_PATH` to `TO_PATH`.
* `list [--recursive] <PATH>...`
List files at `PATH`s. Non-recursive by default.
* `list-disks`.
In these documentation file all mandatory positional arguments are referred as `<parameter>`, named arguments are referred as `[--parameter value]`. All positional parameters could be mentioned as a named parameter with a corresponding name.
* `cd (change-dir, change_dir) [--disk disk] <path>`
Change directory to path `path` on disk `disk` (default value is a current disk). No disk switching happens.
* `copy (cp) [--disk-from disk_1] [--disk-to disk_2] <path-from> <path-to>`.
Recursively copy data from `path-from` at disk `disk_1` (default value is a current disk (parameter `disk` in a non-interactive mode))
to `path-to` at disk `disk_2` (default value is a current disk (parameter `disk` in a non-interactive mode)).
* `current_disk_with_path (current, current_disk, current_path)`
Print current state in format:
`Disk: "current_disk" Path: "current path on current disk"`
* `help [<command>]`
Print help message about command `command`. If `command` is not specified print information about all commands.
* `move (mv) <path-from> <path-to>`.
Move file or directory from `path-from` to `path-to` within current disk.
* `remove (rm, delete) <path>`.
Remove `path` recursively on a current disk.
* `link (ln) <path-from> <path-to>`.
Create a hardlink from `path-from` to `path-to` on a current disk.
* `list (ls) [--recursive] <path>`
List files at `path`s on a current disk. Non-recursive by default.
* `list-disks (list_disks, ls-disks, ls_disks)`.
List disks names.
* `mkdir [--recursive] <PATH>`.
* `mkdir [--recursive] <path>` on a current disk.

# aggThrow
This function can be used for the purpose of testing exception safety. It will throw an exception on creation with the specified probability.
**Syntax**
```sql
aggThrow(throw_prob)
```
**Arguments**
- `throw_prob` — Probability to throw on creation. [Float64](../../data-types/float.md).
**Returned value**
- An exception: `Code: 503. DB::Exception: Aggregate function aggThrow has thrown exception successfully`.
**Example**
Query:
```sql
SELECT number % 2 AS even, aggThrow(number) FROM numbers(10) GROUP BY even;
```
Result:
```response
Received exception:
Code: 503. DB::Exception: Aggregate function aggThrow has thrown exception successfully: While executing AggregatingTransform. (AGGREGATE_FUNCTION_THROW)

# maxMap
Syntax: `maxMap(key, value)` or `maxMap(Tuple(key, value))`
Calculates the maximum from `value` array according to the keys specified in the `key` array.
Passing a tuple of keys and value arrays is identical to passing two arrays of keys and values.
**Syntax**
The number of elements in `key` and `value` must be the same for each row that is totaled.
```sql
maxMap(key, value)

Returns the Unicode (UTF-8) representation (ToUnicode algorithm) of a domain name according to the [Internationalized Domain Names in Applications](https://en.wikipedia.org/wiki/Internationalized_domain_name#Internationalizing_Domain_Names_in_Applications) (IDNA) mechanism.
In case of an error (e.g. because the input is invalid), the input string is returned.
Note that repeated application of `idnaEncode()` and `idnaDecode()` does not necessarily return the original string due to case normalization.

Because `initCap` converts only the first letter of each word to upper case you may observe unexpected behaviour for words containing apostrophes or capital letters. For example:
```sql
SELECT initCap('mother''s daughter'), initCap('joe McAdam');
