#### Backward Incompatible Change
|
||||
* Renamed "inverted indexes" to "full-text indexes" which is a less technical / more user-friendly name. This also changes internal table metadata and breaks tables with existing (experimental) inverted indexes. Please make to drop such indexes before upgrade and re-create them after upgrade. [#62884](https://github.com/ClickHouse/ClickHouse/pull/62884) ([Robert Schulze](https://github.com/rschu1ze)).

[#62884](https://github.com/ClickHouse/ClickHouse/pull/62884) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Usage of functions `neighbor`, `runningAccumulate`, `runningDifferenceStartingWithFirstValue`, `runningDifference` deprecated (because it is error-prone). Proper window functions should be used instead. To enable them back, set `allow_deprecated_error_prone_window_functions = 1` or set `compatibility = '24.4'` or lower. [#63132](https://github.com/ClickHouse/ClickHouse/pull/63132) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Queries from `system.columns` will work faster if there is a large number of columns, but many databases or tables are not granted for `SHOW TABLES`. Note that in previous versions, if you grant `SHOW COLUMNS` to individual columns without granting `SHOW TABLES` to the corresponding tables, the `system.columns` table will show these columns, but in a new version, it will skip the table entirely. Remove trace log messages "Access granted" and "Access denied" that slowed down queries. [#63439](https://github.com/ClickHouse/ClickHouse/pull/63439) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

# MergeTree
|
||||
|
||||
The `MergeTree` engine and other engines of this family (`*MergeTree`) are the most commonly used and most robust ClickHouse table engines.
|
||||
The `MergeTree` engine and other engines of the `MergeTree` family (e.g. `ReplacingMergeTree`, `AggregatingMergeTree` ) are the most commonly used and most robust table engines in ClickHouse.
|
||||
|
||||
Engines in the `MergeTree` family are designed for inserting a very large amount of data into a table. The data is quickly written to the table part by part, then rules are applied for merging the parts in the background. This method is much more efficient than continually rewriting the data in storage during insert.
|
||||
`MergeTree`-family table engines are designed for high data ingest rates and huge data volumes.
|
||||
Insert operations create table parts which are merged by a background process with other table parts.
|
||||
|
||||
Main features:
|
||||
Main features of `MergeTree`-family table engines.
|
||||
|
||||
- Stores data sorted by primary key.
|
||||
- The table's primary key determines the sort order within each table part (clustered index). The primary key also does not reference individual rows but blocks of 8192 rows called granules. This makes primary keys of huge data sets small enough to remain loaded in main memory, while still providing fast access to on-disk data.
|
||||
|
||||
This allows you to create a small sparse index that helps find data faster.
|
||||
- Tables can be partitioned using an arbitrary partition expression. Partition pruning ensures partitions are omitted from reading when the query allows it.
|
||||
|
||||
- Partitions can be used if the [partitioning key](/docs/en/engines/table-engines/mergetree-family/custom-partitioning-key.md) is specified.
|
||||
- Data can be replicated across multiple cluster nodes for high availability, failover, and zero downtime upgrades. See [Data replication](/docs/en/engines/table-engines/mergetree-family/replication.md).
|
||||
|
||||
ClickHouse supports certain operations with partitions that are more efficient than general operations on the same data with the same result. ClickHouse also automatically cuts off the partition data where the partitioning key is specified in the query.
|
||||
- `MergeTree` table engines support various statistics kinds and sampling methods to help query optimization.
|
||||
|
||||
- Data replication support.
|
||||
|
||||
The family of `ReplicatedMergeTree` tables provides data replication. For more information, see [Data replication](/docs/en/engines/table-engines/mergetree-family/replication.md).
|
||||
|
||||
- Data sampling support.
|
||||
|
||||
If necessary, you can set the data sampling method in the table.
|
||||
|
||||
:::info
|
||||
The [Merge](/docs/en/engines/table-engines/special/merge.md/#merge) engine does not belong to the `*MergeTree` family.
|
||||
:::note
|
||||
Despite a similar name, the [Merge](/docs/en/engines/table-engines/special/merge.md/#merge) engine is different from `*MergeTree` engines.
|
||||
:::
|
||||
|
||||
If you need to update rows frequently, we recommend using the [`ReplacingMergeTree`](/docs/en/engines/table-engines/mergetree-family/replacingmergetree.md) table engine. Using `ALTER TABLE my_table UPDATE` to update rows triggers a mutation, which causes parts to be re-written and uses IO/resources. With `ReplacingMergeTree`, you can simply insert the updated rows and the old rows will be replaced according to the table sorting key.

### Query Clauses {#mergetree-query-clauses}
|
||||
|
||||
#### ENGINE
|
||||
|
||||
`ENGINE` — Name and parameters of the engine. `ENGINE = MergeTree()`. The `MergeTree` engine does not have parameters.
|
||||
`ENGINE` — Name and parameters of the engine. `ENGINE = MergeTree()`. The `MergeTree` engine has no parameters.
|
||||
|
||||
#### ORDER_BY
|
||||
|
||||
`ORDER BY` — The sorting key.
|
||||
|
||||
A tuple of column names or arbitrary expressions. Example: `ORDER BY (CounterID, EventDate)`.
|
||||
A tuple of column names or arbitrary expressions. Example: `ORDER BY (CounterID + 1, EventDate)`.
|
||||
|
||||
ClickHouse uses the sorting key as a primary key if the primary key is not defined explicitly by the `PRIMARY KEY` clause.
|
||||
If no primary key is defined (i.e. `PRIMARY KEY` was not specified), ClickHouse uses the the sorting key as primary key.
|
||||
|
||||
Use the `ORDER BY tuple()` syntax, if you do not need sorting, or set `create_table_empty_primary_key_by_default` to `true` to use the `ORDER BY tuple()` syntax by default. See [Selecting the Primary Key](#selecting-the-primary-key).
|
||||
If no sorting is required, you can use syntax `ORDER BY tuple()`.
|
||||
Alternatively, if setting `create_table_empty_primary_key_by_default` is enabled, `ORDER BY tuple()` is implicitly added to `CREATE TABLE` statements. See [Selecting a Primary Key](#selecting-a-primary-key).

`PRIMARY KEY` — The primary key if it [differs from the sorting key](#choosing-a-primary-key-that-differs-from-the-sorting-key). Optional.
|
||||
|
||||
By default the primary key is the same as the sorting key (which is specified by the `ORDER BY` clause). Thus in most cases it is unnecessary to specify a separate `PRIMARY KEY` clause.
|
||||
Specifying a sorting key (using `ORDER BY` clause) implicitly specifies a primary key.
|
||||
It is usually not necessary to specify the primary key in addition to the primary key.
|
||||
|
||||
#### SAMPLE BY
|
||||
|
||||
`SAMPLE BY` — An expression for sampling. Optional.
|
||||
`SAMPLE BY` — A sampling expression. Optional.
|
||||
|
||||
If a sampling expression is used, the primary key must contain it. The result of a sampling expression must be an unsigned integer. Example: `SAMPLE BY intHash32(UserID) ORDER BY (CounterID, EventDate, intHash32(UserID))`.
|
||||
If specified, it must be contained in the primary key.
|
||||
The sampling expression must result in an unsigned integer.
|
||||
|
||||
Example: `SAMPLE BY intHash32(UserID) ORDER BY (CounterID, EventDate, intHash32(UserID))`.
|
||||
|
||||
#### TTL
|
||||
|
||||
`TTL` — A list of rules specifying storage duration of rows and defining logic of automatic parts movement [between disks and volumes](#table_engine-mergetree-multiple-volumes). Optional.
|
||||
`TTL` — A list of rules that specify the storage duration of rows and the logic of automatic parts movement [between disks and volumes](#table_engine-mergetree-multiple-volumes). Optional.
|
||||
|
||||
Expression must have one `Date` or `DateTime` column as a result. Example:
|
||||
```
|
||||
TTL date + INTERVAL 1 DAY
|
||||
```
|
||||
Expression must result in a `Date` or `DateTime`, e.g. `TTL date + INTERVAL 1 DAY`.
|
||||
|
||||
Type of the rule `DELETE|TO DISK 'xxx'|TO VOLUME 'xxx'|GROUP BY` specifies an action to be done with the part if the expression is satisfied (reaches current time): removal of expired rows, moving a part (if expression is satisfied for all rows in a part) to specified disk (`TO DISK 'xxx'`) or to volume (`TO VOLUME 'xxx'`), or aggregating values in expired rows. Default type of the rule is removal (`DELETE`). List of multiple rules can be specified, but there should be no more than one `DELETE` rule.
|
||||
|
||||
|
||||
For more details, see [TTL for columns and tables](#table_engine-mergetree-ttl)

||||
|
||||
### SETTINGS
|
||||
Additional parameters that control the behavior of the `MergeTree` (optional):
|
||||
#### SETTINGS
|
||||
|
||||
#### index_granularity
|
||||
|
||||
`index_granularity` — Maximum number of data rows between the marks of an index. Default value: 8192. See [Data Storage](#mergetree-data-storage).
|
||||
|
||||
#### index_granularity_bytes
|
||||
|
||||
`index_granularity_bytes` — Maximum size of data granules in bytes. Default value: 10Mb. To restrict the granule size only by number of rows, set to 0 (not recommended). See [Data Storage](#mergetree-data-storage).
|
||||
|
||||
#### min_index_granularity_bytes
|
||||
|
||||
`min_index_granularity_bytes` — Min allowed size of data granules in bytes. Default value: 1024b. To provide a safeguard against accidentally creating tables with very low index_granularity_bytes. See [Data Storage](#mergetree-data-storage).
|
||||
|
||||
#### enable_mixed_granularity_parts
|
||||
|
||||
`enable_mixed_granularity_parts` — Enables or disables transitioning to control the granule size with the `index_granularity_bytes` setting. Before version 19.11, there was only the `index_granularity` setting for restricting granule size. The `index_granularity_bytes` setting improves ClickHouse performance when selecting data from tables with big rows (tens and hundreds of megabytes). If you have tables with big rows, you can enable this setting for the tables to improve the efficiency of `SELECT` queries.
|
||||
|
||||
#### use_minimalistic_part_header_in_zookeeper
|
||||
|
||||
`use_minimalistic_part_header_in_zookeeper` — Storage method of the data parts headers in ZooKeeper. If `use_minimalistic_part_header_in_zookeeper=1`, then ZooKeeper stores less data. For more information, see the [setting description](/docs/en/operations/server-configuration-parameters/settings.md/#server-settings-use_minimalistic_part_header_in_zookeeper) in “Server configuration parameters”.
|
||||
|
||||
#### min_merge_bytes_to_use_direct_io
|
||||
|
||||
`min_merge_bytes_to_use_direct_io` — The minimum data volume for merge operation that is required for using direct I/O access to the storage disk. When merging data parts, ClickHouse calculates the total storage volume of all the data to be merged. If the volume exceeds `min_merge_bytes_to_use_direct_io` bytes, ClickHouse reads and writes the data to the storage disk using the direct I/O interface (`O_DIRECT` option). If `min_merge_bytes_to_use_direct_io = 0`, then direct I/O is disabled. Default value: `10 * 1024 * 1024 * 1024` bytes.
|
||||
|
||||
#### merge_with_ttl_timeout
|
||||
|
||||
`merge_with_ttl_timeout` — Minimum delay in seconds before repeating a merge with delete TTL. Default value: `14400` seconds (4 hours).
|
||||
#### merge_with_recompression_ttl_timeout
|
||||
|
||||
`merge_with_recompression_ttl_timeout` — Minimum delay in seconds before repeating a merge with recompression TTL. Default value: `14400` seconds (4 hours).
|
||||
|
||||
#### try_fetch_recompressed_part_timeout
|
||||
|
||||
`try_fetch_recompressed_part_timeout` — Timeout (in seconds) before starting merge with recompression. During this time ClickHouse tries to fetch recompressed part from replica which assigned this merge with recompression. Default value: `7200` seconds (2 hours).
|
||||
|
||||
#### write_final_mark
|
||||
|
||||
`write_final_mark` — Enables or disables writing the final index mark at the end of data part (after the last byte). Default value: 1. Don’t turn it off.
|
||||
|
||||
#### merge_max_block_size
|
||||
|
||||
`merge_max_block_size` — Maximum number of rows in block for merge operations. Default value: 8192.
|
||||
|
||||
#### storage_policy
|
||||
|
||||
`storage_policy` — Storage policy. See [Using Multiple Block Devices for Data Storage](#table_engine-mergetree-multiple-volumes).
|
||||
|
||||
#### min_bytes_for_wide_part
|
||||
|
||||
`min_bytes_for_wide_part`, `min_rows_for_wide_part` — Minimum number of bytes/rows in a data part that can be stored in `Wide` format. You can set one, both or none of these settings. See [Data Storage](#mergetree-data-storage).
|
||||
|
||||
#### max_parts_in_total
|
||||
|
||||
`max_parts_in_total` — Maximum number of parts in all partitions.
|
||||
|
||||
#### max_compress_block_size
|
||||
|
||||
`max_compress_block_size` — Maximum size of blocks of uncompressed data before compressing for writing to a table. You can also specify this setting in the global settings (see [max_compress_block_size](/docs/en/operations/settings/settings.md/#max-compress-block-size) setting). The value specified when table is created overrides the global value for this setting.
|
||||
|
||||
#### min_compress_block_size
|
||||
|
||||
`min_compress_block_size` — Minimum size of blocks of uncompressed data required for compression when writing the next mark. You can also specify this setting in the global settings (see [min_compress_block_size](/docs/en/operations/settings/settings.md/#min-compress-block-size) setting). The value specified when table is created overrides the global value for this setting.
|
||||
|
||||
#### max_partitions_to_read
|
||||
|
||||
`max_partitions_to_read` — Limits the maximum number of partitions that can be accessed in one query. You can also specify setting [max_partitions_to_read](/docs/en/operations/settings/merge-tree-settings.md/#max-partitions-to-read) in the global setting.

# Analyzer
|
||||
|
||||
<BetaBadge />
|
||||
|
||||
## Known incompatibilities
|
||||
|
||||
In ClickHouse version `24.3`, the new query analyzer was enabled by default.
|
||||
Despite fixing a large number of bugs and introducing new optimizations, it also introduces some breaking changes in ClickHouse behaviour. Please read the following changes to determine how to rewrite your queries for the new analyzer.
|
||||
|
||||
### Invalid queries are no longer optimized
|
||||
|
||||
The previous query planning infrastructure applied AST-level optimizations before the query validation step.
|
||||
Optimizations could rewrite the initial query so it becomes valid and can be executed.
|
||||
|
||||
In the new analyzer, query validation takes place before the optimization step.
|
||||
This means that invalid queries that were possible to execute before are now unsupported.
|
||||
In such cases, the query must be fixed manually.
|
||||
|
||||
**Example 1:**
|
||||
|
||||
```sql
|
||||
SELECT number
|
||||
FROM numbers(1)
|
||||
GROUP BY toString(number)
|
||||
```
|
||||
|
||||
The following query uses column `number` in the projection list when only `toString(number)` is available after the aggregation.
|
||||
In the old analyzer, `GROUP BY toString(number)` was optimized into `GROUP BY number,` making the query valid.
|
||||
|
||||
**Example 2:**
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
number % 2 AS n,
|
||||
sum(number)
|
||||
FROM numbers(10)
|
||||
GROUP BY n
|
||||
HAVING number > 5
|
||||
```
|
||||
|
||||
The same problem occurs in this query: column `number` is used after aggregation with another key.
|
||||
The previous query analyzer fixed this query by moving the `number > 5` filter from the `HAVING` clause to the `WHERE` clause.
|
||||
|
||||
To fix the query, you should move all conditions that apply to non-aggregated columns to the `WHERE` section to conform to standard SQL syntax:
|
||||
```sql
|
||||
SELECT
|
||||
number % 2 AS n,
|
||||
sum(number)
|
||||
FROM numbers(10)
|
||||
WHERE number > 5
|
||||
GROUP BY n
|
||||
```
|
||||
|
||||
### CREATE VIEW with invalid query
|
||||
|
||||
The new analyzer always performs type-checking.
|
||||
Previously, it was possible to create a `VIEW` with an invalid `SELECT` query. It would then fail during the first `SELECT` or `INSERT` (in the case of `MATERIALIZED VIEW`).
|
||||
|
||||
Now, it's not possible to create such `VIEW`s anymore.
|
||||
|
||||
**Example:**
|
||||
|
||||
```sql
|
||||
CREATE TABLE source (data String) ENGINE=MergeTree ORDER BY tuple();
|
||||
|
||||
CREATE VIEW some_view
|
||||
AS SELECT JSONExtract(data, 'test', 'DateTime64(3)')
|
||||
FROM source;
|
||||
```
|
||||
|
||||
### Known incompatibilities of the `JOIN` clause
|
||||
|
||||
#### Join using column from projection
|
||||
|
||||
Alias from the `SELECT` list can not be used as a `JOIN USING` key by default.
|
||||
|
||||
A new setting, `analyzer_compatibility_join_using_top_level_identifier`, when enabled, alters the behavior of `JOIN USING` to prefer to resolve identifiers based on expressions from the projection list of the `SELECT` query, rather than using the columns from left table directly.
|
||||
|
||||
**Example:**
|
||||
|
||||
```sql
|
||||
SELECT a + 1 AS b, t2.s
|
||||
FROM Values('a UInt64, b UInt64', (1, 1)) AS t1
|
||||
JOIN Values('b UInt64, s String', (1, 'one'), (2, 'two')) t2
|
||||
USING (b);
|
||||
```
|
||||
|
||||
With `analyzer_compatibility_join_using_top_level_identifier` set to `true`, the join condition is interpreted as `t1.a + 1 = t2.b`, matching the behavior of earlier versions. So, the result will be `2, 'two'`.
|
||||
When the setting is `false`, the join condition defaults to `t1.b = t2.b`, and the query will return `2, 'one'`.
|
||||
If `b` is not present in `t1`, the query will fail with an error.
|
||||
|
||||
#### Changes in behavior with `JOIN USING` and `ALIAS`/`MATERIALIZED` columns
|
||||
|
||||
In the new analyzer, using `*` in a `JOIN USING` query that involves `ALIAS` or `MATERIALIZED` columns will include those columns in the result set by default.
|
||||
|
||||
**Example:**
|
||||
|
||||
```sql
|
||||
CREATE TABLE t1 (id UInt64, payload ALIAS sipHash64(id)) ENGINE = MergeTree ORDER BY id;
|
||||
INSERT INTO t1 VALUES (1), (2);
|
||||
|
||||
CREATE TABLE t2 (id UInt64, payload ALIAS sipHash64(id)) ENGINE = MergeTree ORDER BY id;
|
||||
INSERT INTO t2 VALUES (2), (3);
|
||||
|
||||
SELECT * FROM t1
|
||||
FULL JOIN t2 USING (payload);
|
||||
```
|
||||
|
||||
In the new analyzer, the result of this query will include the `payload` column along with `id` from both tables. In contrast, the previous analyzer would only include these `ALIAS` columns if specific settings (`asterisk_include_alias_columns` or `asterisk_include_materialized_columns`) were enabled, and the columns might appear in a different order.
|
||||
|
||||
To ensure consistent and expected results, especially when migrating old queries to the new analyzer, it is advisable to specify columns explicitly in the `SELECT` clause rather than using `*`.
|
||||
|
||||
#### Handling of Type Modifiers for columns in `USING` Clause
|
||||
|
||||
In the new version of the analyzer, the rules for determining the common supertype for columns specified in the `USING` clause have been standardized to produce more predictable outcomes, especially when dealing with type modifiers like `LowCardinality` and `Nullable`.
|
||||
|
||||
- `LowCardinality(T)` and `T`: When a column of type `LowCardinality(T)` is joined with a column of type `T`, the resulting common supertype will be `T`, effectively discarding the `LowCardinality` modifier.
|
||||
|
||||
- `Nullable(T)` and `T`: When a column of type `Nullable(T)` is joined with a column of type `T`, the resulting common supertype will be `Nullable(T)`, ensuring that the nullable property is preserved.
|
||||
|
||||
**Example:**
|
||||
|
||||
```sql
|
||||
SELECT id, toTypeName(id) FROM Values('id LowCardinality(String)', ('a')) AS t1
|
||||
FULL OUTER JOIN Values('id String', ('b')) AS t2
|
||||
USING (id);
|
||||
```
|
||||
|
||||
In this query, the common supertype for `id` is determined as `String`, discarding the `LowCardinality` modifier from `t1`.
|
||||
|
||||
### Projection column names changes
|
||||
|
||||
During projection names computation, aliases are not substituted.
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
1 + 1 AS x,
|
||||
x + 1
|
||||
SETTINGS allow_experimental_analyzer = 0
|
||||
FORMAT PrettyCompact
|
||||
|
||||
┌─x─┬─plus(plus(1, 1), 1)─┐
|
||||
1. │ 2 │ 3 │
|
||||
└───┴─────────────────────┘
|
||||
|
||||
SELECT
|
||||
1 + 1 AS x,
|
||||
x + 1
|
||||
SETTINGS allow_experimental_analyzer = 1
|
||||
FORMAT PrettyCompact
|
||||
|
||||
┌─x─┬─plus(x, 1)─┐
|
||||
1. │ 2 │ 3 │
|
||||
└───┴────────────┘
|
||||
```
|
||||
|
||||
### Incompatible function arguments types
|
||||
|
||||
In the new analyzer, type inference happens during initial query analysis.
|
||||
This change means that type checks are done before short-circuit evaluation; thus, `if` function arguments must always have a common supertype.
|
||||
|
||||
**Example:**
|
||||
|
||||
The following query fails with `There is no supertype for types Array(UInt8), String because some of them are Array and some of them are not`:
|
||||
|
||||
```sql
|
||||
SELECT toTypeName(if(0, [2, 3, 4], 'String'))
|
||||
```
|
||||
|
||||
### Heterogeneous clusters
|
||||
|
||||
The new analyzer significantly changed the communication protocol between servers in the cluster. Thus, it's impossible to run distributed queries on servers with different `allow_experimental_analyzer` setting values.
|
||||
|
||||
### Mutations are interpreted by previous analyzer
|
||||
|
||||
Mutations are still using the old analyzer.
|
||||
This means some new ClickHouse SQL features can't be used in mutations. For example, the `QUALIFY` clause.
|
||||
Status can be checked [here](https://github.com/ClickHouse/ClickHouse/issues/61563).
|
||||
|
||||
### Unsupported features
|
||||
|
||||
The list of features new analyzer currently doesn't support:
|
||||
|
||||
- Annoy index.
|
||||
- Hypothesis index. Work in progress [here](https://github.com/ClickHouse/ClickHouse/pull/48381).
|
||||
- Window view is not supported. There are no plans to support it in the future.

# Configuration Files
|
||||
|
||||
The ClickHouse server can be configured with configuration files in XML or YAML syntax. In most installation types, the ClickHouse server runs with `/etc/clickhouse-server/config.xml` as default configuration file, but it is also possible to specify the location of the configuration file manually at server startup using command line option `--config-file=` or `-C`. Additional configuration files may be placed into directory `config.d/` relative to the main configuration file, for example into directory `/etc/clickhouse-server/config.d/`. Files in this directory and the main configuration are merged in a preprocessing step before the configuration is applied in ClickHouse server. Configuration files are merged in alphabetical order. To simplify updates and improve modularization, it is best practice to keep the default `config.xml` file unmodified and place additional customization into `config.d/`.
|
||||
(The ClickHouse keeper configuration lives in `/etc/clickhouse-keeper/keeper_config.xml` and thus the additional files need to be placed in `/etc/clickhouse-keeper/keeper_config.d/` )
|
||||
|
||||
|
||||
It is possible to mix XML and YAML configuration files, for example you could have a main configuration file `config.xml` and additional configuration files `config.d/network.xml`, `config.d/timezone.yaml` and `config.d/keeper.yaml`. Mixing XML and YAML within a single configuration file is not supported. XML configuration files should use `<clickhouse>...</clickhouse>` as top-level tag. In YAML configuration files, `clickhouse:` is optional, the parser inserts it implicitly if absent.

### Storage for named collections
|
||||
|
||||
Named collections can either be stored on local disk or in zookeeper/keeper. By default local storage is used.
|
||||
|
||||
To configure named collections storage in keeper and a `type` (equal to either `keeper` or `zookeeper`) and `path` (path in keeper, where named collections will be stored) to `named_collections_storage` section in configuration file:
|
||||
```
|
||||
<clickhouse>

```

An optional configuration parameter `update_timeout_ms` by default is equal to `5000`.

There are three ways to define proxy servers: environment variables, proxy lists, and remote proxy resolvers.

Bypassing proxy servers for specific hosts is also supported with the use of `no_proxy`.

By default, tunneling (i.e, `HTTP CONNECT`) is used to make `HTTPS` requests over `HTTP` proxy. This setting can be used to disable it.
|
||||
|
||||
### no_proxy
|
||||
By default, all requests will go through the proxy. In order to disable it for specific hosts, the `no_proxy` variable must be set.
|
||||
It can be set inside the `<proxy>` clause for list and remote resolvers and as an environment variable for environment resolver.
|
||||
It supports IP addresses, domains, subdomains and `'*'` wildcard for full bypass. Leading dots are stripped just like curl does.
|

Example:
|
||||
|
||||
The below configuration bypasses proxy requests to `clickhouse.cloud` and all of its subdomains (e.g, `auth.clickhouse.cloud`).
|

The same applies to GitLab, even though it has a leading dot. Both `gitlab.com` and `about.gitlab.com` would bypass the proxy.

The values of `merge_tree` settings (for all MergeTree tables) can be viewed in the table `system.merge_tree_settings`, they can be overridden in `config.xml` in the `merge_tree` section, or set in the `SETTINGS` section of each table.
|
||||
System table `system.merge_tree_settings` shows the globally set MergeTree settings.
|
||||
|
||||
These are example overrides for `max_suspicious_broken_parts`:
|
||||
MergeTree settings can be set in the `merge_tree` section of the server config file, or specified for each `MergeTree` table individually in
|
||||
the `SETTINGS` clause of the `CREATE TABLE` statement.
|
||||
|
||||
Example for customizing setting `max_suspicious_broken_parts`:
|
||||
|
||||
Configure the default for all `MergeTree` tables in the server configuration file:
|
||||
|
||||
``` text
|

Enables or disables transitioning to control the granule size with the `index_granularity_bytes` setting. Before version 19.11, there was only the `index_granularity` setting for restricting granule size. The `index_granularity_bytes` setting improves ClickHouse performance when selecting data from tables with big rows (tens and hundreds of megabytes). If you have tables with big rows, you can enable this setting for the tables to improve the efficiency of `SELECT` queries.

### optimize_row_order
|
||||
|
||||
Controls if the row order should be optimized during inserts to improve the compressability of the newly inserted table part.
|
||||
|
||||
Only has an effect for ordinary MergeTree-engine tables. Does nothing for specialized MergeTree engine tables (e.g. CollapsingMergeTree).
|
||||
|
||||
MergeTree tables are (optionally) compressed using [compression codecs](../../sql-reference/statements/create/table.md#column_compression_codec).
|
||||
Generic compression codecs such as LZ4 and ZSTD achieve maximum compression rates if the data exposes patterns.
|
||||
Long runs of the same value typically compress very well.
|
||||
|
||||
If this setting is enabled, ClickHouse attempts to store the data in newly inserted parts in a row order that minimizes the number of equal-value runs across the columns of the new table part.
|
||||
In other words, a small number of equal-value runs mean that individual runs are long and compress well.
|
||||
|
||||
Finding the optimal row order is computationally infeasible (NP hard).
|
||||
Therefore, ClickHouse uses a heuristics to quickly find a row order which still improves compression rates over the original row order.
|
||||
|
||||
<details markdown="1">
|
||||
|
||||
<summary>Heuristics for finding a row order</summary>
|
||||
|
||||
It is generally possible to shuffle the rows of a table (or table part) freely as SQL considers the same table (table part) in different row order equivalent.
|
||||
|
||||
This freedom of shuffling rows is restricted when a primary key is defined for the table.
|
||||
In ClickHouse, a primary key `C1, C2, ..., CN` enforces that the table rows are sorted by columns `C1`, `C2`, ... `Cn` ([clustered index](https://en.wikipedia.org/wiki/Database_index#Clustered)).
|
||||
As a result, rows can only be shuffled within "equivalence classes" of row, i.e. rows which have the same values in their primary key columns.
|
||||
The intuition is that primary keys with high-cardinality, e.g. primary keys involving a `DateTime64` timestamp column, lead to many small equivalence classes.
|
||||
Likewise, tables with a low-cardinality primary key, create few and large equivalence classes.
|
||||
A table with no primary key represents the extreme case of a single equivalence class which spans all rows.
|
||||
|
||||
The fewer and the larger the equivalence classes are, the higher the degree of freedom when re-shuffling rows.
|
||||
|
||||
The heuristics applied to find the best row order within each equivalence class is suggested by D. Lemir, O. Kaser in [Reordering columns for smaller indexes](https://doi.org/10.1016/j.ins.2011.02.002) and based on sorting the rows within each equivalence class by ascending cardinality of the non-primary key columns.
|
||||
It performs three steps:
|
||||
1. Find all equivalence classes based on the row values in primary key columns.
|
||||
2. For each equivalence class, calculate (usually estimate) the cardinalities of the non-primary-key columns.
|
||||
3. For each equivalence class, sort the rows in order of ascending non-primary-key column cardinality.
|
||||
|
||||
</details>
|
||||
|
||||
If enabled, insert operations incur additional CPU costs to analyze and optimize the row order of the new data.
|
||||
INSERTs are expected to take 30-50% longer depending on the data characteristics.
|
||||
Compression rates of LZ4 or ZSTD improve on average by 20-40%.
|
||||
|
||||
This setting works best for tables with no primary key or a low-cardinality primary key, i.e. a table with only few distinct primary key values.
|
||||
High-cardinality primary keys, e.g. involving timestamp columns of type `DateTime64`, are not expected to benefit from this setting.

# covarSampStable
|
||||
|
||||
Calculates the value of `Σ((x - x̅)(y - y̅)) / (n - 1)`. Similar to [covarSamp](../reference/covarsamp.md) but works slower while providing a lower computational error.
|
||||
|
||||
**Syntax**
|
||||
|
||||
```sql
|
||||
covarSampStable(x, y)
|
||||
```
|
||||
|
||||
**Arguments**
|
||||
|
||||
- `x` — first variable. [(U)Int*](../../data-types/int-uint.md), [Float*](../../data-types/float.md), [Decimal](../../data-types/decimal.md).
|
||||
- `y` — second variable. [(U)Int*](../../data-types/int-uint.md), [Float*](../../data-types/float.md), [Decimal](../../data-types/decimal.md).
|
||||
|
||||
**Returned Value**
|
||||
|
||||
- The sample covariance between `x` and `y`. For `n <= 1`, `inf` is returned. [Float64](../../data-types/float.md).
|
||||
|
||||
**Example**
|
||||
|
||||
Query:
|
||||
|
||||
```sql
|
||||
DROP TABLE IF EXISTS series;
|
||||
CREATE TABLE series(i UInt32, x_value Float64, y_value Float64) ENGINE = Memory;

# flameGraph
|
||||
|
||||
Aggregate function which builds a [flamegraph](https://www.brendangregg.com/flamegraphs.html) using the list of stacktraces. Outputs an array of strings which can be used by [flamegraph.pl utility](https://github.com/brendangregg/FlameGraph) to render an SVG of the flamegraph.
|
||||
|
||||
## Syntax
|
||||
|
||||
```sql
|
||||
flameGraph(traces, [size], [ptr])
|
||||
```
|
||||
|
||||
## Parameters
|
||||
|
||||
- `traces` — a stacktrace. [Array](../../data-types/array.md)([UInt64](../../data-types/int-uint.md)).
|
||||
- `size` — an allocation size for memory profiling. (optional - default `1`). [UInt64](../../data-types/int-uint.md).
|
||||
- `ptr` — an allocation address. (optional - default `0`). [UInt64](../../data-types/int-uint.md).
|
||||
|
||||
:::note
|
||||
In the case where `ptr != 0`, a flameGraph will map allocations (size > 0) and deallocations (size < 0) with the same size and ptr.
|
||||
Only allocations which were not freed are shown. Non mapped deallocations are ignored.
|
||||
:::
|
||||
|
||||
## Returned value
|
||||
|
||||
- An array of strings for use with [flamegraph.pl utility](https://github.com/brendangregg/FlameGraph). [Array](../../data-types/array.md)([String](../../data-types/string.md)).
|
||||

The difference between `varSampStable()` and `varSamp()` is that `varSampStable()` is designed to provide a more deterministic and stable result when dealing with floating-point arithmetic.
