* The setting `optimize_trivial_insert_select` is disabled by default. In most cases, it should be beneficial. Nevertheless, if you are seeing slower INSERT SELECT or increased memory usage, you can enable it back or `SET compatibility = '24.6'`. [#58970](https://github.com/ClickHouse/ClickHouse/pull/58970) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Print stacktrace and diagnostic info if `clickhouse-client` or `clickhouse-local` crashes. [#61109](https://github.com/ClickHouse/ClickHouse/pull/61109) ([Alexander Tokmakov](https://github.com/tavplubix)).
* The result of `SHOW INDEX | INDEXES | INDICES | KEYS` was previously sorted by the primary key column names. Since this was unintuitive, the result is now sorted by the position of the primary key columns within the primary key. [#61131](https://github.com/ClickHouse/ClickHouse/pull/61131) ([Robert Schulze](https://github.com/rschu1ze)).
* Change how deduplication for Materialized Views works. Fixed a lot of cases like: - on destination table: data is split for 2 or more blocks and that blocks is considered as duplicate when that block is inserted in parallel. - on MV destination table: the equal blocks are deduplicated, that happens when MV often produces equal data as a result for different input data due to performing aggregation. - on MV destination table: the equal blocks which comes from different MV are deduplicated. [#61601](https://github.com/ClickHouse/ClickHouse/pull/61601) ([Sema Checherinda](https://github.com/CheSema)).
* Support reading partitioned data DeltaLake data. Infer DeltaLake schema by reading metadata instead of data. [#63201](https://github.com/ClickHouse/ClickHouse/pull/63201) ([Kseniia Sumarokova](https://github.com/kssenii)).
* In composable protocols TLS layer accepted only `certificateFile` and `privateKeyFile` parameters. https://clickhouse.com/docs/en/operations/settings/composable-protocols. [#63985](https://github.com/ClickHouse/ClickHouse/pull/63985) ([Anton Ivashkin](https://github.com/ianton-ru)).
* Added profile event `SelectQueriesWithPrimaryKeyUsage` which indicates how many SELECT queries use the primary key to evaluate the WHERE clause. [#64492](https://github.com/ClickHouse/ClickHouse/pull/64492) ([0x01f](https://github.com/0xfei)).

This could happen when `PARTITION` columns have sparse serialization and window functions are executed in parallel. [#66579](https://github.com/ClickHouse/ClickHouse/pull/66579) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Backported in [#66946](https://github.com/ClickHouse/ClickHouse/issues/66946): Fix `Method getResultType is not supported for QUERY query node` error when scalar subquery was used as the first argument of IN (with new analyzer).

# 2024 Changelog
### ClickHouse release v24.4.4.113-stable (d63a54957bd) FIXME as compared to v24.4.3.25-stable (a915dd4eda4)
#### Improvement
* Backported in [#65884](https://github.com/ClickHouse/ClickHouse/issues/65884): Always start Keeper with sufficient amount of threads in global thread pool. [#64444](https://github.com/ClickHouse/ClickHouse/pull/64444) ([Duc Canh Le](https://github.com/canhld94)).
* Backported in [#65303](https://github.com/ClickHouse/ClickHouse/issues/65303): Returned back the behaviour of how ClickHouse works and interprets Tuples in CSV format. This change effectively reverts https://github.com/ClickHouse/ClickHouse/pull/60994 and makes it available only under a few settings: `output_format_csv_serialize_tuple_into_separate_columns`, `input_format_csv_deserialize_separate_columns_into_tuple` and `input_format_csv_try_infer_strings_from_quoted_tuples`. [#65170](https://github.com/ClickHouse/ClickHouse/pull/65170) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Backported in [#65894](https://github.com/ClickHouse/ClickHouse/issues/65894): Respect cgroup CPU limit in Keeper. [#65819](https://github.com/ClickHouse/ClickHouse/pull/65819) ([Antonio Andelic](https://github.com/antonio2368)).
#### Critical Bug Fix (crash, LOGICAL_ERROR, data loss, RBAC)

* Backported in [#65435](https://github.com/ClickHouse/ClickHouse/issues/65435): Forbid `QUALIFY` clause in the old analyzer. The old analyzer ignored `QUALIFY`, so it could lead to unexpected data removal in mutations. [#65356](https://github.com/ClickHouse/ClickHouse/pull/65356) ([Dmitry Novik](https://github.com/novikd)).
* Backported in [#65448](https://github.com/ClickHouse/ClickHouse/issues/65448): Use correct memory alignment for Distinct combinator.

* Backported in [#65668](https://github.com/ClickHouse/ClickHouse/issues/65668): Disable `non-intersecting-parts` optimization for queries with `FINAL` in case of `read-in-order` optimization was enabled. This could lead to an incorrect query result. As a workaround, disable `do_not_merge_across_partitions_select_final` and `split_parts_ranges_into_intersecting_and_non_intersecting_final` before this fix is merged. [#65505](https://github.com/ClickHouse/ClickHouse/pull/65505) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

* Backported in [#66299](https://github.com/ClickHouse/ClickHouse/issues/66299): Better handling of join conditions involving `IS NULL` checks (for example `ON (a = b AND (a IS NOT NULL) AND (b IS NOT NULL) ) OR ( (a IS NULL) AND (b IS NULL) )` is rewritten to `ON a <=> b`), fix incorrect optimization when condition other then `IS NULL` are present. [#65835](https://github.com/ClickHouse/ClickHouse/pull/65835) ([vdimir](https://github.com/vdimir)).

In more detail, containers often run their process in the root cgroup which has an empty name. In that case, ClickHouse ignored the CPU limits set by cgroups v2. [#66237](https://github.com/ClickHouse/ClickHouse/pull/66237) ([filimonov](https://github.com/filimonov)).
* Backported in [#66360](https://github.com/ClickHouse/ClickHouse/issues/66360): Fix the `Not-ready set` error when a subquery with `IN` is used in the constraint. [#66261](https://github.com/ClickHouse/ClickHouse/pull/66261) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

* Backported in [#66951](https://github.com/ClickHouse/ClickHouse/issues/66951): Fix an invalid result for queries with `WINDOW`. This could happen when `PARTITION` columns have sparse serialization and window functions are executed in parallel. [#66579](https://github.com/ClickHouse/ClickHouse/pull/66579) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Backported in [#66757](https://github.com/ClickHouse/ClickHouse/issues/66757): Fix `Unknown identifier` and `Column is not under aggregate function` errors for queries with the expression `(column IS NULL).` The bug was triggered by [#65088](https://github.com/ClickHouse/ClickHouse/issues/65088), with the disabled analyzer only.

`InterpreterSelectQuery` uses `ExpressionAnalyzer` and `ExpressionActions` machinery for query analysis and transformations. This is where most rule-based query optimizations are performed. `ExpressionAnalyzer` is quite messy and should be rewritten: various query transformations and optimizations should be extracted into separate classes to allow for modular transformations of the query.
To address current problems that exist in interpreters, a new `InterpreterSelectQueryAnalyzer` is being developed. It is a new version of `InterpreterSelectQuery` that does not use `ExpressionAnalyzer` and introduces an additional abstraction level between `AST` and `QueryPipeline` called `QueryTree`.

Instead create a Git submodule to pull third-party code from an external upstream repository.

- If the library needs patching, create a fork of the upstream repository in the [ClickHouse organization on GitHub](https://github.com/ClickHouse).
In the latter case, we aim to isolate custom patches as much as possible from upstream commits.
To that end, create a branch with prefix `clickhouse/` from the branch or tag you want to integrate, e.g. `clickhouse/master` (for branch `master`) or `clickhouse/release/vX.Y.Z` (for tag `release/vX.Y.Z`).
This ensures that pulls from the upstream repository into the fork will leave custom `clickhouse/` branches unaffected.
Submodules in `contrib/` must only track `clickhouse/` branches of forked third-party repositories.
To that end, create a branch with prefix `ClickHouse/` from the branch or tag you want to integrate, e.g. `ClickHouse/2024_2` (for branch `2024_2`) or `ClickHouse/release/vX.Y.Z` (for tag `release/vX.Y.Z`).
Avoid following upstream development branches `master`/ `main` / `dev` (i.e., prefix branches `ClickHouse/master` / `ClickHouse/main` / `ClickHouse/dev` in the fork repository).
Such branches are moving targets which make proper versioning harder.
"Prefix branches" ensure that pulls from the upstream repository into the fork will leave custom `ClickHouse/` branches unaffected.
Submodules in `contrib/` must only track `ClickHouse/` branches of forked third-party repositories.
Patches are only applied against `clickhouse/` branches of external libraries.
For that, push the patch as a branch with `clickhouse/`, e.g. `clickhouse/fix-some-desaster`.
Then create a PR from the new branch against the custom tracking branch with `clickhouse/` prefix, (e.g. `clickhouse/master` or `clickhouse/release/vX.Y.Z`) and merge the patch.
Patches are only applied against `ClickHouse/` branches of external libraries.
There are two ways to do that:
- you like to make a new fix against a `ClickHouse/`-prefix branch in the forked repository, e.g. a sanitizer fix. In that case, push the fix as a branch with `ClickHouse/` prefix, e.g. `ClickHouse/fix-sanitizer-disaster`. Then create a PR from the new branch against the custom tracking branch, e.g. `ClickHouse/2024_2 <-- ClickHouse/fix-sanitizer-disaster` and merge the PR.
- you update the submodule and need to re-apply earlier patches. In this case, re-creating old PRs is overkill. Instead, simply cherry-pick older commits into the new `ClickHouse/` branch (corresponding to the new version). Feel free to squash commits of PRs that had multiple commits. In the best case, we did contribute custom patches back to upstream and can omit patches in the new version.
Once the submodule has been updated, bump the submodule in ClickHouse to point to the new hash in the fork.
Create patches of third-party libraries with the official repository in mind and consider contributing the patch back to the upstream repository.
This makes sure that others will also benefit from the patch and it will not be a maintenance burden for the ClickHouse team.
To pull upstream changes into the submodule, you can use two methods:
- (less work but less clean): merge upstream `master` into the corresponding `clickhouse/` tracking branch in the forked repository. You will need to resolve merge conflicts with previous custom patches. This method can be used when the `clickhouse/` branch tracks an upstream development branch like `master`, `main`, `dev`, etc.
- (more work but cleaner): create a new branch with `clickhouse/` prefix from the upstream commit or tag you like to integrate. Then re-apply all existing patches using new PRs (or squash them into a single PR). This method can be used when the `clickhouse/` branch tracks a specific upstream version branch or tag. It is cleaner in the sense that custom patches and upstream changes are better isolated from each other.
Once the submodule has been updated, bump the submodule in ClickHouse to point to the new hash in the fork.

- For row-based formats the number of rows in one Kafka message can be controlled by setting `kafka_max_rows_per_message`.
- For block-based formats we cannot divide block into smaller parts, but the number of rows in one block can be controlled by general setting [max_block_size](../../../operations/settings/settings.md#setting-max_block_size).
## Experimental engine to store committed offsets in ClickHouse Keeper
If `allow_experimental_kafka_offsets_storage_in_keeper` is enabled, then two more settings can be specified to the Kafka table engine:
- `kafka_keeper_path` specifies the path to the table in ClickHouse Keeper
- `kafka_replica_name` specifies the replica name in ClickHouse Keeper
Either both of the settings must be specified or neither of them. When both of them are specified, then a new, experimental Kafka engine will be used. The new engine doesn't depend on storing the committed offsets in Kafka, but stores them in ClickHouse Keeper. It still tries to commit the offsets to Kafka, but it only depends on those offsets when the table is created. In any other circumstances (table is restarted, or recovered after some error) the offsets stored in ClickHouse Keeper will be used as an offset to continue consuming messages from. Apart from the committed offset, it also stores how many messages were consumed in the last batch, so if the insert fails, the same amount of messages will be consumed, thus enabling deduplication if necessary.
Example:
``` sql
CREATE TABLE experimental_kafka (key UInt64, value UInt64)
ENGINE = Kafka('localhost:19092', 'my-topic', 'my-consumer', 'JSONEachRow')
SETTINGS
kafka_keeper_path = '/clickhouse/{database}/experimental_kafka',
kafka_replica_name = 'r1'
SETTINGS allow_experimental_kafka_offsets_storage_in_keeper=1;
```
Or to utilize the `uuid` and `replica` macros similarly to ReplicatedMergeTree:
``` sql
CREATE TABLE experimental_kafka (key UInt64, value UInt64)
ENGINE = Kafka('localhost:19092', 'my-topic', 'my-consumer', 'JSONEachRow')
SETTINGS
kafka_keeper_path = '/clickhouse/{database}/{uuid}',
kafka_replica_name = '{replica}'
SETTINGS allow_experimental_kafka_offsets_storage_in_keeper=1;
```
### Known limitations
As the new engine is experimental, it is not production ready yet. There are few known limitations of the implementation:
- The biggest limitation is the engine doesn't support direct reading. Reading from the engine using materialized views and writing to the engine work, but direct reading doesn't. As a result, all direct `SELECT` queries will fail.
- Rapidly dropping and recreating the table or specifying the same ClickHouse Keeper path to different engines might cause issues. As best practice you can use the `{uuid}` in `kafka_keeper_path` to avoid clashing paths.
- To make repeatable reads, messages cannot be consumed from multiple partitions on a single thread. On the other hand, the Kafka consumers have to be polled regularly to keep them alive. As a result of these two objectives, we decided to only allow creating multiple consumers if `kafka_thread_per_consumer` is enabled, otherwise it is too complicated to avoid issues regarding polling consumers regularly.
- Consumers created by the new storage engine do not show up in [`system.kafka_consumers`](../../../operations/system-tables/kafka_consumers.md) table.

# TimeSeries Engine [Experimental]
A table engine storing time series, i.e. a set of values associated with timestamps and tags (or labels):
```
metric_name1[tag1=value1, tag2=value2, ...] = {timestamp1: value1, timestamp2: value2, ...}
metric_name2[...] = ...
```
:::info
This is an experimental feature that may change in backwards-incompatible ways in the future releases.
Enable usage of the TimeSeries table engine
with [allow_experimental_time_series_table](../../../operations/settings/settings.md#allow-experimental-time-series-table) setting.
Input the command `set allow_experimental_time_series_table = 1`.
:::
## Syntax {#syntax}
``` sql
CREATE TABLE name [(columns)] ENGINE=TimeSeries
[SETTINGS var1=value1, ...]
[DATA db.data_table_name | DATA ENGINE data_table_engine(arguments)]
[TAGS db.tags_table_name | TAGS ENGINE tags_table_engine(arguments)]
[METRICS db.metrics_table_name | METRICS ENGINE metrics_table_engine(arguments)]
```
## Usage {#usage}
It's easier to start with everything set by default (it's allowed to create a `TimeSeries` table without specifying a list of columns):
``` sql
CREATE TABLE my_table ENGINE=TimeSeries
```
Then this table can be used with the following protocols (a port must be assigned in the server configuration):
- [prometheus remote-write](../../../interfaces/prometheus.md#remote-write)
- [prometheus remote-read](../../../interfaces/prometheus.md#remote-read)
## Target tables {#target-tables}
A `TimeSeries` table doesn't have its own data, everything is stored in its target tables.
This is similar to how a [materialized view](../../../sql-reference/statements/create/view#materialized-view) works,
with the difference that a materialized view has one target table
whereas a `TimeSeries` table has three target tables named [data]{#data-table}, [tags]{#tags-table], and [metrics]{#metrics-table}.
The target tables can be either specified explicitly in the `CREATE TABLE` query
or the `TimeSeries` table engine can generate inner target tables automatically.
The target tables are the following:
1. The _data_ table {#data-table} contains time series associated with some identifier.
The _data_ table must have columns:
| Name | Mandatory? | Default type | Possible types | Description |
|---|---|---|---|---|
| `id` | [x] | `UUID` | any | Identifies a combination of a metric names and tags |
| `timestamp` | [x] | `DateTime64(3)` | `DateTime64(X)` | A time point |
| `value` | [x] | `Float64` | `Float32` or `Float64` | A value associated with the `timestamp` |
2. The _tags_ table {#tags-table} contains identifiers calculated for each combination of a metric name and tags.
The _tags_ table must have columns:
| Name | Mandatory? | Default type | Possible types | Description |
|---|---|---|---|---|
| `id` | [x] | `UUID` | any (must match the type of `id` in the [data]{#data-table} table) | An `id` identifies a combination of a metric name and tags. The DEFAULT expression specifies how to calculate such an identifier |
| `metric_name` | [x] | `LowCardinality(String)` | `String` or `LowCardinality(String)` | The name of a metric |
| `<tag_value_column>` | [ ] | `String` | `String` or `LowCardinality(String)` or `LowCardinality(Nullable(String))` | The value of a specific tag, the tag's name and the name of a corresponding column are specified in the [tags_to_columns](#settings) setting |
| `tags` | [x] | `Map(LowCardinality(String), String)` | `Map(String, String)` or `Map(LowCardinality(String), String)` or `Map(LowCardinality(String), LowCardinality(String))` | Map of tags excluding the tag `__name__` containing the name of a metric and excluding tags with names enumerated in the [tags_to_columns](#settings) setting |
| `all_tags` | [ ] | `Map(String, String)` | `Map(String, String)` or `Map(LowCardinality(String), String)` or `Map(LowCardinality(String), LowCardinality(String))` | Ephemeral column, each row is a map of all the tags excluding only the tag `__name__` containing the name of a metric. The only purpose of that column is to be used while calculating `id` |
| `min_time` | [ ] | `Nullable(DateTime64(3))` | `DateTime64(X)` or `Nullable(DateTime64(X))` | Minimum timestamp of time series with that `id`. The column is created if [store_min_time_and_max_time](#settings) is `true` |
| `max_time` | [ ] | `Nullable(DateTime64(3))` | `DateTime64(X)` or `Nullable(DateTime64(X))` | Maximum timestamp of time series with that `id`. The column is created if [store_min_time_and_max_time](#settings) is `true` |
3. The _metrics_ table {#metrics-table} contains some information about metrics been collected, the types of those metrics and their descriptions.
The _metrics_ table must have columns:
| Name | Mandatory? | Default type | Possible types | Description |
|---|---|---|---|---|
| `metric_family_name` | [x] | `String` | `String` or `LowCardinality(String)` | The name of a metric family |
| `type` | [x] | `String` | `String` or `LowCardinality(String)` | The type of a metric family, one of "counter", "gauge", "summary", "stateset", "histogram", "gaugehistogram" |
| `unit` | [x] | `String` | `String` or `LowCardinality(String)` | The unit used in a metric |
| `help` | [x] | `String` | `String` or `LowCardinality(String)` | The description of a metric |
Any row inserted into a `TimeSeries` table will be in fact stored in those three target tables.
A `TimeSeries` table contains all those columns from the [data]{#data-table}, [tags]{#tags-table}, [metrics]{#metrics-table} tables.
## Creation {#creation}
There are multiple ways to create a table with the `TimeSeries` table engine.
The simplest statement
``` sql
CREATE TABLE my_table ENGINE=TimeSeries
```
will actually create the following table (you can see that by executing `SHOW CREATE TABLE my_table`):
``` sql
CREATE TABLE my_table
(
`id` UUID DEFAULT reinterpretAsUUID(sipHash128(metric_name, all_tags)),
`timestamp` DateTime64(3),
`value` Float64,
`metric_name` LowCardinality(String),
`tags` Map(LowCardinality(String), String),
`all_tags` Map(String, String),
`min_time` Nullable(DateTime64(3)),
`max_time` Nullable(DateTime64(3)),
`metric_family_name` String,
`type` String,
`unit` String,
`help` String
)
ENGINE = TimeSeries
DATA ENGINE = MergeTree ORDER BY (id, timestamp)
DATA INNER UUID '01234567-89ab-cdef-0123-456789abcdef'
TAGS ENGINE = AggregatingMergeTree PRIMARY KEY metric_name ORDER BY (metric_name, id)
TAGS INNER UUID '01234567-89ab-cdef-0123-456789abcdef'
METRICS ENGINE = ReplacingMergeTree ORDER BY metric_family_name
METRICS INNER UUID '01234567-89ab-cdef-0123-456789abcdef'
```
So the columns were generated automatically and also there are three inner UUIDs in this statement -
one per each inner target table that was created.
(Inner UUIDs are not shown normally until setting
[show_table_uuid_in_table_create_query_if_not_nil](../../../operations/settings/settings#show_table_uuid_in_table_create_query_if_not_nil)
is set.)
Inner target tables have names like `.inner_id.data.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`,
`.inner_id.tags.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`, `.inner_id.metrics.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
and each target table has columns which is a subset of the columns of the main `TimeSeries` table:
``` sql
CREATE TABLE default.`.inner_id.data.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
(
`id` UUID,
`timestamp` DateTime64(3),
`value` Float64
)
ENGINE = MergeTree
ORDER BY (id, timestamp)
```
``` sql
CREATE TABLE default.`.inner_id.tags.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
(
`id` UUID DEFAULT reinterpretAsUUID(sipHash128(metric_name, all_tags)),
`metric_name` LowCardinality(String),
`tags` Map(LowCardinality(String), String),
`all_tags` Map(String, String) EPHEMERAL,
`min_time` SimpleAggregateFunction(min, Nullable(DateTime64(3))),
`max_time` SimpleAggregateFunction(max, Nullable(DateTime64(3)))
)
ENGINE = AggregatingMergeTree
PRIMARY KEY metric_name
ORDER BY (metric_name, id)
```
``` sql
CREATE TABLE default.`.inner_id.metrics.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
(
`metric_family_name` String,
`type` String,
`unit` String,
`help` String
)
ENGINE = ReplacingMergeTree
ORDER BY metric_family_name
```
## Adjusting types of columns {#adjusting-column-types}
You can adjust the types of almost any column of the inner target tables by specifying them explicitly
while defining the main table. For example,
``` sql
CREATE TABLE my_table
(
timestamp DateTime64(6)
) ENGINE=TimeSeries
```
will make the inner [data]{#data-table} table store timestamp in microseconds instead of milliseconds:
``` sql
CREATE TABLE default.`.inner_id.data.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
(
`id` UUID,
`timestamp` DateTime64(6),
`value` Float64
)
ENGINE = MergeTree
ORDER BY (id, timestamp)
```
## The `id` column {#id-column}
The `id` column contains identifiers, every identifier is calculated for a combination of a metric name and tags.
The DEFAULT expression for the `id` column is an expression which will be used to calculate such identifiers.
Both the type of the `id` column and that expression can be adjusted by specifying them explicitly:
``` sql
CREATE TABLE my_table
(
id UInt64 DEFAULT sipHash64(metric_name, all_tags)
) ENGINE=TimeSeries
```
## The `tags` and `all_tags` columns {#tags-and-all-tags}
There are two columns containing maps of tags - `tags` and `all_tags`. In this example they mean the same, however they can be different
if setting `tags_to_columns` is used. This setting allows to specify that a specific tag should be stored in a separate column instead of storing
in a map inside the `tags` column:
``` sql
CREATE TABLE my_table ENGINE=TimeSeries SETTINGS = {'instance': 'instance', 'job': 'job'}
```
This statement will add columns
```
`instance` String,
`job` String
```
to the definition of both `my_table` and its inner [tags]{#tags-table} target table. In this case the `tags` column will not contain tags `instance` and `job`,
but the `all_tags` column will contain them. The `all_tags` column is ephemeral and its only purpose to be used in the DEFAULT expression
for the `id` column.
The types of columns can be adjusted by specifying them explicitly:
``` sql
CREATE TABLE my_table (instance LowCardinality(String), job LowCardinality(Nullable(String)))
ENGINE=TimeSeries SETTINGS = {'instance': 'instance', 'job': 'job'}
```
## Table engines of inner target tables {#inner-table-engines}
By default inner target tables use the following table engines:
- the [data]{#data-table} table uses [MergeTree](../mergetree-family/mergetree);
- the [tags]{#tags-table} table uses [AggregatingMergeTree](../mergetree-family/aggregatingmergetree) because the same data is often inserted multiple times to this table so we need a way
to remove duplicates, and also because it's required to do aggregation for columns `min_time` and `max_time`;
- the [metrics]{#metrics-table} table uses [ReplacingMergeTree](../mergetree-family/replacingmergetree) because the same data is often inserted multiple times to this table so we need a way
to remove duplicates.
Other table engines also can be used for inner target tables if it's specified so:
``` sql
CREATE TABLE my_table ENGINE=TimeSeries
DATA ENGINE=ReplicatedMergeTree
TAGS ENGINE=ReplicatedAggregatingMergeTree
METRICS ENGINE=ReplicatedReplacingMergeTree
```
## External target tables {#external-target-tables}
It's possible to make a `TimeSeries` table use a manually created table:
``` sql
CREATE TABLE data_for_my_table
(
`id` UUID,
`timestamp` DateTime64(3),
`value` Float64
)
ENGINE = MergeTree
ORDER BY (id, timestamp);
CREATE TABLE tags_for_my_table ...
CREATE TABLE metrics_for_my_table ...
CREATE TABLE my_table ENGINE=TimeSeries DATA data_for_my_table TAGS tags_for_my_table METRICS metrics_for_my_table;
```
## Settings {#settings}
Here is a list of settings which can be specified while defining a `TimeSeries` table:
| Name | Type | Default | Description |
|---|---|---|---|
| `tags_to_columns` | Map | {} | Map specifying which tags should be put to separate columns in the [tags]{#tags-table} table. Syntax: `{'tag1': 'column1', 'tag2' : column2, ...}` |
| `use_all_tags_column_to_generate_id` | Bool | true | When generating an expression to calculate an identifier of a time series, this flag enables using the `all_tags` column in that calculation |
| `store_min_time_and_max_time` | Bool | true | If set to true then the table will store `min_time` and `max_time` for each time series |
| `aggregate_min_time_and_max_time` | Bool | true | When creating an inner target `tags` table, this flag enables using `SimpleAggregateFunction(min, Nullable(DateTime64(3)))` instead of just `Nullable(DateTime64(3))` as the type of the `min_time` column, and the same for the `max_time` column |
| `filter_by_min_time_and_max_time` | Bool | true | If set to true then the table will use the `min_time` and `max_time` columns for filtering time series |
# Functions {#functions}
Here is a list of functions supporting a `TimeSeries` table as an argument:
- [timeSeriesData](../../../sql-reference/table-functions/timeSeriesData.md)
- [timeSeriesTags](../../../sql-reference/table-functions/timeSeriesTags.md)
- [timeSeriesMetrics](../../../sql-reference/table-functions/timeSeriesMetrics.md)

# Prometheus protocols
## Exposing metrics {#expose}
:::note
ClickHouse Cloud does not currently support connecting to Prometheus. To be notified when this feature is supported, please contact support@clickhouse.com.
:::
ClickHouse can expose its own metrics for scraping from Prometheus:
```xml
<prometheus>
<port>9363</port>
<endpoint>/metrics</endpoint>
<metrics>true</metrics>
<asynchronous_metrics>true</asynchronous_metrics>
<events>true</events>
<errors>true</errors>
</prometheus>
Section `<prometheus.handlers>` can be used to make more extended handlers.
This section is similar to [<http_handlers>](/en/interfaces/http) but works for prometheus protocols:
```xml
<prometheus>
<port>9363</port>
<handlers>
<my_rule_1>

<handler>
<type>expose_metrics</type>
<metrics>true</metrics>
<asynchronous_metrics>true</asynchronous_metrics>
<events>true</events>
<errors>true</errors>
</handler>
</my_rule_1>
</handlers>
</prometheus>
```
Settings:
| Name | Default | Description |
|---|---|---|---|
| `port` | none | Port for serving the exposing metrics protocol. |
| `endpoint` | `/metrics` | HTTP endpoint for scraping metrics by prometheus server. Starts with `/`. Should not be used with the `<handlers>` section. |
| `url` / `headers` / `method` | none | Filters used to find a matching handler for a request. Similar to the fields with the same names in the [<http_handlers>](/en/interfaces/http) section. |
| `metrics` | true | Expose metrics from the [system.metrics](/en/operations/system-tables/metrics) table. |
| `asynchronous_metrics` | true | Expose current metrics values from the [system.asynchronous_metrics](/en/operations/system-tables/asynchronous_metrics) table. |
| `events` | true | Expose metrics from the [system.events](/en/operations/system-tables/events) table. |

Check (replace `127.0.0.1` with the IP addr or hostname of your ClickHouse server):
```bash
curl 127.0.0.1:9363/metrics
```
## Remote-write protocol {#remote-write}
ClickHouse supports the [remote-write](https://prometheus.io/docs/specs/remote_write_spec/) protocol.
Data are received by this protocol and written to a [TimeSeries](/en/engines/table-engines/special/time_series) table
(which should be created beforehand).
```xml
<prometheus>
<port>9363</port>
<handlers>
<my_rule_1>
<url>/write</url>
<handler>
<type>remote_write</type
<database>db_name</database>
<table>time_series_table</table>
</handler>
</my_rule_1>
</handlers>
</prometheus>
```
Settings:
| Name | Default | Description |
|---|---|---|---|
| `port` | none | Port for serving the `remote-write` protocol. |
| `url` / `headers` / `method` | none | Filters used to find a matching handler for a request. Similar to the fields with the same names in the [<http_handlers>](/en/interfaces/http) section. |

## Remote-read protocol {#remote-read}
ClickHouse supports the [remote-read](https://prometheus.io/docs/prometheus/latest/querying/remote_read_api/) protocol.
Data are read from a [TimeSeries](/en/engines/table-engines/special/time_series) table and sent via this protocol.
```xml
<prometheus>
<port>9363</port>
<handlers>
<my_rule_1>
<url>/read</url>
<handler>
<type>remote_read</type
<database>db_name</database>
<table>time_series_table</table>
</handler>
</my_rule_1>
</handlers>
</prometheus>
```

@ -123,7 +123,7 @@ To ensure consistent and expected results, especially when migrating old queries
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.

title: groupConcat
---
Calculates a concatenated string from a group of strings, optionally separated by a delimiter, and optionally limited by a maximum number of elements.
**Syntax**
``` sql
groupConcat[(delimiter [, limit])](expression);
```
**Arguments**
- `expression` — The expression or column name that outputs strings to be concatenated..
- `delimiter` — A [string](../../../sql-reference/data-types/string.md) that will be used to separate concatenated values. This parameter is optional and defaults to an empty string if not specified.
- `limit` — A positive [integer](../../../sql-reference/data-types/int-uint.md) specifying the maximum number of elements to concatenate. If more elements are present, excess elements are ignored. This parameter is optional.
:::note
If delimiter is specified without limit, it must be the first parameter. If both delimiter and limit are specified, delimiter must precede limit.
:::
**Returned value**
- Returns a [string](../../../sql-reference/data-types/string.md) consisting of the concatenated values of the column or expression. If the group has no elements or only null elements, and the function does not specify a handling for only null values, the result is a nullable string with a null value.
**Examples**
Input table:
``` text
┌─id─┬─name─┐
│ 1 │ John│
│ 2 │ Jane│
│ 3 │ Bob│
└────┴──────┘
```
1. Basic usage without a delimiter:
Query:
``` sql
SELECT groupConcat(Name) FROM Employees;
```
Result:
``` text
JohnJaneBob
```
This concatenates all names into one continuous string without any separator.
2. Using comma as a delimiter:
Query:
``` sql
SELECT groupConcat(', ')(Name) FROM Employees;
```
Result:
``` text
John, Jane, Bob
```
This output shows the names separated by a comma followed by a space.
3. Limiting the number of concatenated elements
Query:
``` sql
SELECT groupConcat(', ', 2)(Name) FROM Employees;
```
Result:
``` text
John, Jane
```
This query limits the output to the first two names, even though there are more names in the table.

## polygonsDistanceSpherical
Calculates the minimal distance between two points where one point belongs to the first polygon and the second to another polygon. Spherical means that coordinates are interpreted as coordinates on a pure and ideal sphere, which is not true for the Earth. Using this type of coordinate system speeds up execution, but of course is not precise.
