|
||||
* Backported in [#67637](https://github.com/ClickHouse/ClickHouse/issues/67637): Fix for occasional deadlock in Context::getDDLWorker. [#66843](https://github.com/ClickHouse/ClickHouse/pull/66843) ([Alexander Gololobov](https://github.com/davenger)).
|
||||
* Backported in [#67820](https://github.com/ClickHouse/ClickHouse/issues/67820): Fix possible deadlock on query cancel with parallel replicas. [#66905](https://github.com/ClickHouse/ClickHouse/pull/66905) ([Nikita Taranov](https://github.com/nickitat)).

|
||||
* Backported in [#67713](https://github.com/ClickHouse/ClickHouse/issues/67713): Fix reloading SQL UDFs with UNION. Previously, restarting the server could make UDF invalid. [#67665](https://github.com/ClickHouse/ClickHouse/pull/67665) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Backported in [#67995](https://github.com/ClickHouse/ClickHouse/issues/67995): Validate experimental/suspicious data types in ALTER ADD/MODIFY COLUMN. [#67911](https://github.com/ClickHouse/ClickHouse/pull/67911) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
|
||||
#### Critical Bug Fix (crash, LOGICAL_ERROR, data loss, RBAC)
|
||||
|
||||
* Backported in [#67818](https://github.com/ClickHouse/ClickHouse/issues/67818): Only relevant to the experimental Variant data type. Fix crash with Variant + AggregateFunction type. [#67122](https://github.com/ClickHouse/ClickHouse/pull/67122) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Backported in [#67766](https://github.com/ClickHouse/ClickHouse/issues/67766): Fix crash of `uniq` and `uniqTheta ` with `tuple()` argument. Closes [#67303](https://github.com/ClickHouse/ClickHouse/issues/67303). [#67306](https://github.com/ClickHouse/ClickHouse/pull/67306) ([flynn](https://github.com/ucasfl)).

* Backported in [#67840](https://github.com/ClickHouse/ClickHouse/issues/67840): Fix potential stack overflow in `JSONMergePatch` function.

@ -27,23 +27,23 @@ Avoid dumping copies of external code into the library directory.

|
||||
|
||||
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`).

|
||||
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.

|

## 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:

## 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>
|
||||
<url>/metrics</url>
|
||||
<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. |
|

|
||||
| `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>

|
||||
| `table` | none | The name of a [TimeSeries](/en/engines/table-engines/special/time_series) table to write data received by the `remote-write` protocol. This name can optionally contain the name of a database too. |
|
||||
| `database` | none | The name of a database where the table specified in the `table` setting is located if it's not specified in the `table` setting. |
|
||||
|
||||
## 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.
|
||||

`timeSeriesMetrics(db_name.time_series_table)` - Returns the [metrics](../../engines/table-engines/integrations/time-series.md#metrics-table) table
|
||||
used by table `db_name.time_series_table` which table engine is [TimeSeries](../../engines/table-engines/integrations/time-series.md):

SELECT * FROM timeSeriesMetrics(db_name.time_series_table);
|
||||
SELECT * FROM timeSeriesMetrics('db_name.time_series_table');

# percent_rank
|
||||
|
||||
returns the relative rank (i.e. percentile) of rows within a window partition.
|
||||
|
||||
**Syntax**
|
||||
|
||||
Alias: `percentRank` (case-sensitive)
|
||||
|
||||
```sql
|
||||
percent_rank (column_name)
|
||||
OVER ([[PARTITION BY grouping_column] [ORDER BY sorting_column]
|
||||
[RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING]] | [window_name])
|
||||
FROM table_name
|
||||
WINDOW window_name as ([PARTITION BY grouping_column] [ORDER BY sorting_column] RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
|
||||
```
|
||||
|
||||
The default and required window frame definition is `RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING`.
|
||||
|
||||
For more detail on window function syntax see: [Window Functions - Syntax](./index.md/#syntax).
|
||||
