# Embed a set of resource files into a resulting object file.
#
# Signature: `clickhouse_embed_binaries(TARGET <target> RESOURCE_DIR <dir> RESOURCES <resource> ...)
#
# This will generate a static library target named `<target>`, which contains the contents of
# each `<resource>` file. The files should be located in `<dir>`. <dir> defaults to
# ${CMAKE_CURRENT_SOURCE_DIR}, and the resources may not be empty.
#
# Each resource will result in three symbols in the final archive, based on the name `<resource>`.
# These are:
# 1. `_binary_<name>_start`: Points to the start of the binary data from `<resource>`.
# 2. `_binary_<name>_end`: Points to the end of the binary data from `<resource>`.
# 2. `_binary_<name>_size`: Points to the size of the binary data from `<resource>`.
#
# `<name>` is a normalized name derived from `<resource>`, by replacing the characters "./-" with
# the character "_", and the character "+" with "_PLUS_". This scheme is similar to those generated
# by `ld -r -b binary`, and matches the expectations in `./base/common/getResource.cpp`.

# Settings Overview
There are multiple ways to define ClickHouse settings. Settings are configured in layers, and each subsequent layer redefines the previous values of a setting.
There are two main groups of ClickHouse settings:
The order of priority for defining a setting is:
- Global server settings
- Query-level settings
1. Settings in the `users.xml` server configuration file
The main distinction between global server settings and query-level settings is that
global server settings must be set in configuration files while query-level settings
can be set in configuration files or with SQL queries.
- Set in the element `<profiles>`.
Read about [global server settings](/docs/en/operations/server-configuration-parameters/settings.md) to learn more about configuring your ClickHouse server at the global server level.
2. Session settings
Read about [query-level settings](/docs/en/operations/settings/settings-query-level.md) to learn more about configuring your ClickHouse server at the query-level.
- Send `SET setting=value` from the ClickHouse console client in interactive mode.
Similarly, you can use ClickHouse sessions in the HTTP protocol. To do this, you need to specify the `session_id` HTTP parameter.
3. Query settings
- When starting the ClickHouse console client in non-interactive mode, set the startup parameter `--setting=value`.
- When using the HTTP API, pass CGI parameters (`URL?setting_1=value&setting_2=value...`).
- Define settings in the [SETTINGS](../../sql-reference/statements/select/index.md#settings-in-select-query) clause of the SELECT query. The setting value is applied only to that query and is reset to the default or previous value after the query is executed.
View the [Settings](./settings.md) page for a description of the ClickHouse settings.
## Converting a Setting to its Default Value
If you change a setting and would like to revert it back to its default value, set the value to `DEFAULT`. The syntax looks like:
```sql
SET setting_name = DEFAULT
```
For example, the default value of `max_insert_block_size` is 1048449. Suppose you change its value to 100000:
```sql
SET max_insert_block_size=100000;
SELECT value FROM system.settings where name='max_insert_block_size';
```
The response is:
```response
┌─value──┐
│ 100000 │
└────────┘
```
The following command sets its value back to 1048449:
```sql
SET max_insert_block_size=DEFAULT;
SELECT value FROM system.settings where name='max_insert_block_size';
```
The setting is now back to its default:
```response
┌─value───┐
│ 1048449 │
└─────────┘
```
## Custom Settings {#custom_settings}
In addition to the common [settings](../../operations/settings/settings.md), users can define custom settings.
A custom setting name must begin with one of predefined prefixes. The list of these prefixes must be declared in the [custom_settings_prefixes](../../operations/server-configuration-parameters/settings.md#custom_settings_prefixes) parameter in the server configuration file.
```xml
<custom_settings_prefixes>custom_</custom_settings_prefixes>
```
To define a custom setting use `SET` command:
```sql
SET custom_a = 123;
```
To get the current value of a custom setting use `getSetting()` function:
```sql
SELECT getSetting('custom_a');
```

## interval_output_format {#interval_output_format}
Allows choosing different output formats of the text representation of interval types.
Possible values:
- `kusto` - KQL-style output format.
ClickHouse outputs intervals in [KQL format](https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-timespan-format-strings#the-constant-c-format-specifier). For example, `toIntervalDay(2)` would be formatted as `2.00:00:00`. Please note that for interval types of varying length (ie. `IntervalMonth` and `IntervalYear`) the average number of seconds per interval is taken into account.
- `numeric` - Numeric output format.
ClickHouse outputs intervals as their underlying numeric representation. For example, `toIntervalDay(2)` would be formatted as `2`.
Default value: `numeric`.

There are multiple ways to set ClickHouse query-level settings. Settings are configured in layers, and each subsequent layer redefines the previous values of a setting.
The order of priority for defining a setting is:
1. Applying a setting to a user directly, or within a settings profile
- SQL (recommended)
- adding one or more XML or YAML files to `/etc/clickhouse-server/users.d`
2. Session settings
- Send `SET setting=value` from the ClickHouse Cloud SQL console or
`clickhouse client` in interactive mode. Similarly, you can use ClickHouse
sessions in the HTTP protocol. To do this, you need to specify the
`session_id` HTTP parameter.
3. Query settings
- When starting `clickhouse client` in non-interactive mode, set the startup
parameter `--setting=value`.
- When using the HTTP API, pass CGI parameters (`URL?setting_1=value&setting_2=value...`).
- Define settings in the
[SETTINGS](../../sql-reference/statements/select/index.md#settings-in-select-query)
clause of the SELECT query. The setting value is applied only to that query
and is reset to the default or previous value after the query is executed.
## Examples
These examples all set the value of the `async_insert` setting to `1`, and
show how to examine the settings in a running system.
### Using SQL to apply a setting to a user directly
This creates the user `ingester` with the setting `async_inset = 1`:
```sql
CREATE USER ingester
IDENTIFIED WITH sha256_hash BY '7e099f39b84ea79559b3e85ea046804e63725fd1f46b37f281276aae20f86dc3'
# highlight-next-line
SETTINGS async_insert = 1
```
#### Examine the settings profile and assignment
```sql
SHOW ACCESS
```
```response
┌─ACCESS─────────────────────────────────────────────────────────────────────────────┐
│ ... │
# highlight-next-line
│ CREATE USER ingester IDENTIFIED WITH sha256_password SETTINGS async_insert = true │
│ ... │
└────────────────────────────────────────────────────────────────────────────────────┘
```
### Using SQL to create a settings profile and assign to a user
This creates the profile `log_ingest` with the setting `async_inset = 1`:
```sql
CREATE
SETTINGS PROFILE log_ingest SETTINGS async_insert = 1
```
This creates the user `ingester` and assigns the user the settings profile `log_ingest`:
```sql
CREATE USER ingester
IDENTIFIED WITH sha256_hash BY '7e099f39b84ea79559b3e85ea046804e63725fd1f46b37f281276aae20f86dc3'
# highlight-next-line
SETTINGS PROFILE log_ingest
```
### Using XML to create a settings profile and user
```xml title=/etc/clickhouse-server/users.d/users.xml
<clickhouse>
# highlight-start
<profiles>
<log_ingest>
<async_insert>1</async_insert>
</log_ingest>

<access_management>1</access_management>
<named_collection_control>1</named_collection_control>
</default>
</users>
</clickhouse>
```
#### Examine the settings profile and assignment
```sql
SHOW ACCESS
```
```response
┌─ACCESS─────────────────────────────────────────────────────────────────────────────┐
│ CREATE USER default IDENTIFIED WITH sha256_password │
# highlight-next-line
│ CREATE USER ingester IDENTIFIED WITH sha256_password SETTINGS PROFILE log_ingest │
│ CREATE SETTINGS PROFILE default │
# highlight-next-line
│ CREATE SETTINGS PROFILE log_ingest SETTINGS async_insert = true │
│ CREATE SETTINGS PROFILE readonly SETTINGS readonly = 1 │
│ ... │
└────────────────────────────────────────────────────────────────────────────────────┘
```
### Assign a setting to a session
```sql
SET async_insert =1;
SELECT value FROM system.settings where name='async_insert';
```
```response
┌─value──┐
│ 1 │
└────────┘
```
### Assign a setting during a query
```sql
INSERT INTO YourTable
# highlight-next-line
SETTINGS async_insert=1
VALUES (...)
```
## Converting a Setting to its Default Value
If you change a setting and would like to revert it back to its default value, set the value to `DEFAULT`. The syntax looks like:
```sql
SET setting_name = DEFAULT
```
For example, the default value of `async_insert` is `0`. Suppose you change its value to `1`:
```sql
SET async_insert = 1;
SELECT value FROM system.settings where name='async_insert';
```
The response is:
```response
┌─value──┐
│ 1 │
└────────┘
```
The following command sets its value back to 0:
```sql
SET async_insert = DEFAULT;
SELECT value FROM system.settings where name='async_insert';
```
The setting is now back to its default:
```response
┌─value───┐
│ 0 │
└─────────┘
```
## Custom Settings {#custom_settings}
In addition to the common [settings](../../operations/settings/settings.md), users can define custom settings.
A custom setting name must begin with one of predefined prefixes. The list of these prefixes must be declared in the [custom_settings_prefixes](../../operations/server-configuration-parameters/settings.md#custom_settings_prefixes) parameter in the server configuration file.
```xml
<custom_settings_prefixes>custom_</custom_settings_prefixes>
```
To define a custom setting use `SET` command:
```sql
SET custom_a = 123;
```
To get the current value of a custom setting use `getSetting()` function:
```sql
SELECT getSetting('custom_a');
```

The first phase of a grace join reads the right table and splits it into N buckets depending on the hash value of key columns (initially, N is `grace_hash_join_initial_buckets`). This is done in a way to ensure that each bucket can be processed independently. Rows from the first bucket are added to an in-memory hash table while the others are saved to disk. If the hash table grows beyond the memory limit (e.g., as set by [`max_bytes_in_join`](/docs/en/operations/settings/query-complexity.md/#settings-max_bytes_in_join)), the number of buckets is increased and the assigned bucket for each row.

# jemalloc_bins
Contains information about memory allocations done via jemalloc allocator in different size classes (bins) aggregated from all arenas.
These statistics might not be absolutely accurate because of thread local caching in jemalloc.
Columns:
- `index` (UInt64) — Index of the bin ordered by size
- `large` (Bool) — True for large allocations and False for small
- `size` (UInt64) — Size of allocations in this bin
- `allocations` (UInt64) — Number of allocations
- `deallocations` (UInt64) — Number of deallocations
**Example**
Find the sizes of allocations that contributed the most to the current overall memory usage.
``` sql
SELECT
*,
allocations - deallocations AS active_allocations,
size * active_allocations AS allocated_bytes
FROM system.jemalloc_bins
WHERE allocated_bytes > 0
ORDER BY allocated_bytes DESC
LIMIT 10

# Arithmetic Functions
The result type of all arithmetic functions is the smallest type which can represent all possible results. Size promotion happens for integers up to 32 bit, e.g. `UInt8 + UInt16 = UInt32`. If one of the inters has 64 or more bits, the result is of the same type as the bigger of the input integers, e.g. `UInt16 + UInt128 = UInt128`. While this introduces a risk of overflows around the value range boundary, it ensures that calculations are performed quickly using the maximum native integer width of 64 bit.
Arithmetic functions work for any two operands of type `UInt8`, `UInt16`, `UInt32`, `UInt64`, `Int8`, `Int16`, `Int32`, `Int64`, `Float32`, or `Float64`.
The result of addition or multiplication of two integers is unsigned unless one of the integers is signed.
Before performing the operation, both operands are casted to the result type. The result type is determined as follows (unless specified
differently in the function documentation below):
- If both operands are up to 32 bits wide, the size of the result type will be the size of the next bigger type following the bigger of the
two operands (integer size promotion). For example, `UInt8 + UInt16 = UInt32` or `Float32 * Float32 = Float64`.
- If one of the operands has 64 or more bits, the size of the result type will be the same size as the bigger of the two operands. For
example, `UInt32 + UInt128 = UInt128` or `Float32 * Float64 = Float64`.
- If one of the operands is signed, the result type will also be signed, otherwise it will be signed. For example, `UInt32 * Int32 = Int64`.
These rules make sure that the result type will be the smallest type which can represent all possible results. While this introduces a risk
of overflows around the value range boundary, it ensures that calculations are performed quickly using the maximum native integer width of
64 bit. This behavior also guarantees compatibility with many other databases which provide 64 bit integers (BIGINT) as the biggest integer
type.

ClickHouse supports Common Table Expressions ([CTE](https://en.wikipedia.org/wiki/Hierarchical_and_recursive_queries_in_SQL)) and substitutes the code defined in the `WITH` clause in all places of use for the rest of `SELECT` query. Named subqueries can be included to the current and child query context in places where table objects are allowed. Recursion is prevented by hiding the current level CTEs from the WITH expression.
Please note that CTEs do not guarantee the same results in all places they are called because the query will be re-executed for each use case.
An example of such behavior is below
``` sql
with cte_numbers as
(
select
num
from generateRandom('num UInt64', NULL)
limit 1000000
)
select
count()
from cte_numbers
where num in (select num from cte_numbers)
```
If CTEs were to pass exactly the results and not just a piece of code, you would always see `1000000`
However, due to the fact that we are referring `cte_numbers` twice, random numbers are generated each time and, accordingly, we see different random results, `280501, 392454, 261636, 196227` and so on...

### Шаблон
Шаблон поддерживает следующие виды плейсхолдеров:
- `%a` — Полное исходное имя файла (например "sample.csv").
- `%f` — Исходное имя файла без расширения (например "sample").
- `%e` — Оригинальное расширение файла с точкой (например ".csv").
- `%t` — Текущее время (в микросекундах).
