### ClickHouse release v21.12, 2021-12-13
#### Backward Incompatible Change
* *A fix for a feature that previously had unwanted behaviour.* Do not allow direct select for Kafka/RabbitMQ/FileLog. Can be enabled by setting `stream_like_engine_allow_direct_select`. Direct select will be not allowed even if enabled by setting, in case there is an attached materialized view. For Kafka and RabbitMQ direct selectm if allowed, will not commit massages by default. To enable commits with direct select, user must use storage level setting `kafka{rabbitmq}_commit_on_select=1` (default `0`). [#31053](https://github.com/ClickHouse/ClickHouse/pull/31053) ([Kseniia Sumarokova](https://github.com/kssenii)).
* *A slight change in behaviour of a new function.* Return unquoted string in JSON_VALUE. Closes [#27965](https://github.com/ClickHouse/ClickHouse/issues/27965). [#31008](https://github.com/ClickHouse/ClickHouse/pull/31008) ([Kseniia Sumarokova](https://github.com/kssenii)).
* *Setting rename.* Add custom null representation support for TSV/CSV input formats. Fix deserialing Nullable(String) in TSV/CSV/JSONCompactStringsEachRow/JSONStringsEachRow input formats. Rename `output_format_csv_null_representation` and `output_format_tsv_null_representation` to `format_csv_null_representation` and `format_tsv_null_representation` accordingly. [#30497](https://github.com/ClickHouse/ClickHouse/pull/30497) ([Kruglov Pavel](https://github.com/Avogar)).
* *Further deprecation of already unused code.* This is relevant only for users of ClickHouse versions older than 20.6. A "leader election" mechanism is removed from `ReplicatedMergeTree`, because multiple leaders are supported since 20.6. If you are upgrading from an older version and some replica with an old version is a leader, then server will fail to start after upgrade. Stop replicas with old version to make new version start. After that it will not be possible to downgrade to version older than 20.6. [#32140](https://github.com/ClickHouse/ClickHouse/pull/32140) ([tavplubix](https://github.com/tavplubix)).
#### New Feature
* Implemented more of the ZooKeeper Four Letter Words commands in clickhouse-keeper: https://zookeeper.apache.org/doc/r3.4.8/zookeeperAdmin.html#sc_zkCommands. [#28981](https://github.com/ClickHouse/ClickHouse/pull/28981) ([JackyWoo](https://github.com/JackyWoo)). Now `clickhouse-keeper` is feature complete.
* Support for `Bool` data type. [#31072](https://github.com/ClickHouse/ClickHouse/pull/31072) ([kevin wan](https://github.com/MaxWk)).
* Support for `PARTITION BY` in File, URL, HDFS storages and with `INSERT INTO` table function. Closes [#30273](https://github.com/ClickHouse/ClickHouse/issues/30273). [#30690](https://github.com/ClickHouse/ClickHouse/pull/30690) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Added `CONSTRAINT ... ASSUME ...` (without checking during `INSERT`). Added query transformation to CNF (https://github.com/ClickHouse/ClickHouse/issues/11749) for more convenient optimization. Added simple query rewriting using constraints (only simple matching now, will be improved to support <,=,>... later). Added ability to replace heavy columns with light columns if it's possible. [#18787](https://github.com/ClickHouse/ClickHouse/pull/18787) ([Nikita Vasilev](https://github.com/nikvas0)).
* Basic access authentication for http/url functions. [#31648](https://github.com/ClickHouse/ClickHouse/pull/31648) ([michael1589](https://github.com/michael1589)).
* Support `INTERVAL` type in `STEP` clause for `WITH FILL` modifier. [#30927](https://github.com/ClickHouse/ClickHouse/pull/30927) ([Anton Popov](https://github.com/CurtizJ)).
* Add support for parallel reading from multiple files and support globs in `FROM INFILE` clause. [#30135](https://github.com/ClickHouse/ClickHouse/pull/30135) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
* Add support for `Identifier` table and database query parameters. Closes [#27226](https://github.com/ClickHouse/ClickHouse/issues/27226). [#28668](https://github.com/ClickHouse/ClickHouse/pull/28668) ([Nikolay Degterinsky](https://github.com/evillique)).
* *TLDR: Major improvements of completeness and consistency of text formats.* Refactor formats `TSV`, `TSVRaw`, `CSV` and `JSONCompactEachRow`, `JSONCompactStringsEachRow`, remove code duplication, add base interface for formats with `-WithNames` and `-WithNamesAndTypes` suffixes. Add formats `CSVWithNamesAndTypes`, `TSVRawWithNames`, `TSVRawWithNamesAndTypes`, `JSONCompactEachRowWIthNames`, `JSONCompactStringsEachRowWIthNames`, `RowBinaryWithNames`. Support parallel parsing for formats `TSVWithNamesAndTypes`, `TSVRaw(WithNames/WIthNamesAndTypes)`, `CSVWithNamesAndTypes`, `JSONCompactEachRow(WithNames/WIthNamesAndTypes)`, `JSONCompactStringsEachRow(WithNames/WIthNamesAndTypes)`. Support columns mapping and types checking for `RowBinaryWithNamesAndTypes` format. Add setting `input_format_with_types_use_header` which specify if we should check that types written in <format_name>`WIthNamesAndTypes` format matches with table structure. Add setting `input_format_csv_empty_as_default` and use it in CSV format instead of `input_format_defaults_for_omitted_fields` (because this setting should not control `csv_empty_as_default`). Fix usage of setting `input_format_defaults_for_omitted_fields` (it was used only as `csv_empty_as_default`, but it should control calculation of default expressions for omitted fields). Fix Nullable input/output in `TSVRaw` format, make this format fully compatible with inserting into TSV. Fix inserting NULLs in `LowCardinality(Nullable)` when `input_format_null_as_default` is enabled (previously default values was inserted instead of actual NULLs). Fix strings deserialization in `JSONStringsEachRow`/`JSONCompactStringsEachRow` formats (strings were parsed just until first '\n' or '\t'). Add ability to use `Raw` escaping rule in Template input format. Add diagnostic info for JSONCompactEachRow(WithNames/WIthNamesAndTypes) input format. Fix bug with parallel parsing of `-WithNames` formats in case when setting `min_chunk_bytes_for_parallel_parsing` is less than bytes in a single row. [#30178](https://github.com/ClickHouse/ClickHouse/pull/30178) ([Kruglov Pavel](https://github.com/Avogar)). Allow to print/parse names and types of colums in `CustomSeparated` input/output format. Add formats `CustomSeparatedWithNames/WithNamesAndTypes` similar to `TSVWithNames/WithNamesAndTypes`. [#31434](https://github.com/ClickHouse/ClickHouse/pull/31434) ([Kruglov Pavel](https://github.com/Avogar)).
* Aliyun OSS Storage support. [#31286](https://github.com/ClickHouse/ClickHouse/pull/31286) ([cfcz48](https://github.com/cfcz48)).
* Exposes all settings of the global thread pool in the configuration file. [#31285](https://github.com/ClickHouse/ClickHouse/pull/31285) ([Tomáš Hromada](https://github.com/gyfis)).
* Introduced window functions `exponentialTimeDecayedSum`, `exponentialTimeDecayedMax`, `exponentialTimeDecayedCount` and `exponentialTimeDecayedAvg` which are more effective than `exponentialMovingAverage` for bigger windows. Also more use-cases were covered. [#29799](https://github.com/ClickHouse/ClickHouse/pull/29799) ([Vladimir Chebotarev](https://github.com/excitoon)).
* Add option to compress logs before writing them to a file using LZ4. Closes [#23860](https://github.com/ClickHouse/ClickHouse/issues/23860). [#29219](https://github.com/ClickHouse/ClickHouse/pull/29219) ([Nikolay Degterinsky](https://github.com/evillique)).
* Support `JOIN ON 1 = 1` that have CROSS JOIN semantic. This closes [#25578](https://github.com/ClickHouse/ClickHouse/issues/25578). [#25894](https://github.com/ClickHouse/ClickHouse/pull/25894) ([Vladimir C](https://github.com/vdimir)).
* Add Map combinator for `Map` type. - Rename old `sum-, min-, max- Map` for mapped arrays to `sum-, min-, max- MappedArrays`. [#24539](https://github.com/ClickHouse/ClickHouse/pull/24539) ([Ildus Kurbangaliev](https://github.com/ildus)).
* Make reading from HTTP retriable. Closes [#29696](https://github.com/ClickHouse/ClickHouse/issues/29696). [#29894](https://github.com/ClickHouse/ClickHouse/pull/29894) ([Kseniia Sumarokova](https://github.com/kssenii)).
#### Experimental Feature
* `WINDOW VIEW` to enable stream processing in ClickHouse. [#8331](https://github.com/ClickHouse/ClickHouse/pull/8331) ([vxider](https://github.com/Vxider)).
* Drop support for using Ordinary databases with `MaterializedMySQL`. [#31292](https://github.com/ClickHouse/ClickHouse/pull/31292) ([Stig Bakken](https://github.com/stigsb)).
* Implement the commands BACKUP and RESTORE for the Log family. This feature is under development. [#30688](https://github.com/ClickHouse/ClickHouse/pull/30688) ([Vitaly Baranov](https://github.com/vitlibar)).
#### Performance Improvement
* Reduce memory usage when reading with `s3` / `url` / `hdfs` formats `Parquet`, `ORC`, `Arrow` (controlled by setting `input_format_allow_seeks`, enabled by default). Also add setting `remote_read_min_bytes_for_seek` to control seeks. Closes [#10461](https://github.com/ClickHouse/ClickHouse/issues/10461). Closes [#16857](https://github.com/ClickHouse/ClickHouse/issues/16857). [#30936](https://github.com/ClickHouse/ClickHouse/pull/30936) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Add optimizations for constant conditions in JOIN ON, ref [#26928](https://github.com/ClickHouse/ClickHouse/issues/26928). [#27021](https://github.com/ClickHouse/ClickHouse/pull/27021) ([Vladimir C](https://github.com/vdimir)).
* Support parallel formatting for all text formats, except `JSONEachRowWithProgress` and `PrettyCompactMonoBlock`. [#31489](https://github.com/ClickHouse/ClickHouse/pull/31489) ([Kruglov Pavel](https://github.com/Avogar)).
* Speed up count over nullable columns. [#31806](https://github.com/ClickHouse/ClickHouse/pull/31806) ([Raúl Marín](https://github.com/Algunenano)).
* Speed up `avg` and `sumCount` aggregate functions. [#31694](https://github.com/ClickHouse/ClickHouse/pull/31694) ([Raúl Marín](https://github.com/Algunenano)).
* Improve performance of JSON and XML output formats. [#31673](https://github.com/ClickHouse/ClickHouse/pull/31673) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Improve performance of syncing data to block device. This closes [#31181](https://github.com/ClickHouse/ClickHouse/issues/31181). [#31229](https://github.com/ClickHouse/ClickHouse/pull/31229) ([zhanglistar](https://github.com/zhanglistar)).
* Fixing query performance issue in `LiveView` tables. Fixes [#30831](https://github.com/ClickHouse/ClickHouse/issues/30831). [#31006](https://github.com/ClickHouse/ClickHouse/pull/31006) ([vzakaznikov](https://github.com/vzakaznikov)).
* Speed up query parsing. [#31949](https://github.com/ClickHouse/ClickHouse/pull/31949) ([Raúl Marín](https://github.com/Algunenano)).
* Allow to split `GraphiteMergeTree` rollup rules for plain/tagged metrics (optional `rule_type` field). [#25122](https://github.com/ClickHouse/ClickHouse/pull/25122) ([Michail Safronov](https://github.com/msaf1980)).
* Remove excessive `DESC TABLE` requests for `remote()` (in case of `remote('127.1', system.one)` (i.e. identifier as the db.table instead of string) there was excessive `DESC TABLE` request). [#32019](https://github.com/ClickHouse/ClickHouse/pull/32019) ([Azat Khuzhin](https://github.com/azat)).
* Optimize function `tupleElement` to reading of subcolumn with enabled setting `optimize_functions_to_subcolumns`. [#31261](https://github.com/ClickHouse/ClickHouse/pull/31261) ([Anton Popov](https://github.com/CurtizJ)).
* Optimize function `mapContains` to reading of subcolumn `key` with enabled settings `optimize_functions_to_subcolumns`. [#31218](https://github.com/ClickHouse/ClickHouse/pull/31218) ([Anton Popov](https://github.com/CurtizJ)).
* Add settings `merge_tree_min_rows_for_concurrent_read_for_remote_filesystem` and `merge_tree_min_bytes_for_concurrent_read_for_remote_filesystem`. [#30970](https://github.com/ClickHouse/ClickHouse/pull/30970) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Skipping mutations of different partitions in `StorageMergeTree`. [#21326](https://github.com/ClickHouse/ClickHouse/pull/21326) ([Vladimir Chebotarev](https://github.com/excitoon)).
#### Improvement
* Do not allow to drop a table or dictionary if some tables or dictionaries depend on it. [#30977](https://github.com/ClickHouse/ClickHouse/pull/30977) ([tavplubix](https://github.com/tavplubix)).
* Allow versioning of aggregate function states. Now we can introduce backward compatible changes in serialization format of aggregate function states. Closes [#12552](https://github.com/ClickHouse/ClickHouse/issues/12552). [#24820](https://github.com/ClickHouse/ClickHouse/pull/24820) ([Kseniia Sumarokova](https://github.com/kssenii)).

* Fix JSON_VALUE/JSON_QUERY with quoted identifiers. This allows to have spaces in json path. Closes [#30971](https://github.com/ClickHouse/ClickHouse/issues/30971). [#31003](https://github.com/ClickHouse/ClickHouse/pull/31003) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Using `formatRow` function with not row-oriented formats led to segfault. Don't allow to use this function with such formats (because it doesn't make sense). [#31001](https://github.com/ClickHouse/ClickHouse/pull/31001) ([Kruglov Pavel](https://github.com/Avogar)).
* Fix bug which broke select queries if they happened after dropping materialized view. Found in [#30691](https://github.com/ClickHouse/ClickHouse/issues/30691). [#30997](https://github.com/ClickHouse/ClickHouse/pull/30997) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Skip `max_partition_size_to_drop check` in case of ATTACH PARTITION ... FROM and MOVE PARTITION ... [#30995](https://github.com/ClickHouse/ClickHouse/pull/30995) ([Amr Alaa](https://github.com/amralaa-MSFT)).
* Fix some corner cases with `INTERSECT` and `EXCEPT` operators. Closes [#30803](https://github.com/ClickHouse/ClickHouse/issues/30803). [#30965](https://github.com/ClickHouse/ClickHouse/pull/30965) ([Kseniia Sumarokova](https://github.com/kssenii)).
#### Build/Testing/Packaging Improvement
* Fix incorrect filtering result on non-x86 builds. This closes [#31417](https://github.com/ClickHouse/ClickHouse/issues/31417). This closes [#31524](https://github.com/ClickHouse/ClickHouse/issues/31524). [#31574](https://github.com/ClickHouse/ClickHouse/pull/31574) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Make ClickHouse build fully reproducible (byte identical on different machines). This closes [#22113](https://github.com/ClickHouse/ClickHouse/issues/22113). [#31899](https://github.com/ClickHouse/ClickHouse/pull/31899) ([alexey-milovidov](https://github.com/alexey-milovidov)). Remove filesystem path to the build directory from binaries to enable reproducible builds. This needed for [#22113](https://github.com/ClickHouse/ClickHouse/issues/22113). [#31838](https://github.com/ClickHouse/ClickHouse/pull/31838) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Use our own CMakeLists for `zlib-ng`, `cassandra`, `mariadb-connector-c` and `xz`, `re2`, `sentry`, `gsasl`, `arrow`, `protobuf`. This is needed for [#20151](https://github.com/ClickHouse/ClickHouse/issues/20151). Part of [#9226](https://github.com/ClickHouse/ClickHouse/issues/9226). A small step towards removal of annoying trash from the build system. [#30599](https://github.com/ClickHouse/ClickHouse/pull/30599) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Hermetic builds: use fixed version of libc and make sure that no source or binary files from the host OS are using during build. This closes [#27133](https://github.com/ClickHouse/ClickHouse/issues/27133). This closes [#21435](https://github.com/ClickHouse/ClickHouse/issues/21435). This closes [#30462](https://github.com/ClickHouse/ClickHouse/issues/30462). [#30011](https://github.com/ClickHouse/ClickHouse/pull/30011) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Adding function `getFuzzerData()` to easily fuzz particular functions. This closes [#23227](https://github.com/ClickHouse/ClickHouse/issues/23227). [#27526](https://github.com/ClickHouse/ClickHouse/pull/27526) ([Alexey Boykov](https://github.com/mathalex)).
* More correct setting up capabilities inside Docker. [#31802](https://github.com/ClickHouse/ClickHouse/pull/31802) ([Constantine Peresypkin](https://github.com/pkit)).
* Enable clang `-fstrict-vtable-pointers`, `-fwhole-program-vtables` compile options. [#20151](https://github.com/ClickHouse/ClickHouse/pull/20151) ([Maksim Kita](https://github.com/kitaisreal)).
* Avoid downloading toolchain tarballs for cross-compiling for FreeBSD. [#31672](https://github.com/ClickHouse/ClickHouse/pull/31672) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Initial support for risc-v. See development/build-cross-riscv for quirks and build command that was tested. [#31309](https://github.com/ClickHouse/ClickHouse/pull/31309) ([Vladimir Smirnov](https://github.com/Civil)).
* Support compile in arm machine with parameter "-DENABLE_TESTS=OFF". [#31007](https://github.com/ClickHouse/ClickHouse/pull/31007) ([zhanghuajie](https://github.com/zhanghuajieHIT)).

The key for partitioning by month allows reading only those data blocks which contain dates from the proper range. In this case, the data block may contain data for many dates (up to an entire month). Within a block, data is sorted by primary key, which might not contain the date as the first column. Because of this, using a query with only a date condition that does not specify the primary key prefix will cause more data to be read than for a single date.

# gRPC Interface {#grpc-interface}
## Introduction {#grpc-interface-introduction}
ClickHouse supports [gRPC](https://grpc.io/) interface. It is an open source remote procedure call system that uses HTTP/2 and [Protocol Buffers](https://en.wikipedia.org/wiki/Protocol_Buffers). The implementation of gRPC in ClickHouse supports:
- SSL;
- authentication;
- sessions;
- compression;
- parallel queries through the same channel;
- cancellation of queries;
- getting progress and logs;
- external tables.
The specification of the interface is described in [clickhouse_grpc.proto](https://github.com/ClickHouse/ClickHouse/blob/master/src/Server/grpc_protos/clickhouse_grpc.proto).
## gRPC Configuration {#grpc-interface-configuration}
To use the gRPC interface set `grpc_port` in the main [server configuration](../operations/configuration-files.md). Other configuration options see in the following example:
```xml
<grpc_port>9100</grpc_port>
<grpc>
<enable_ssl>false</enable_ssl>
<!-- The following two files are used only if SSL is enabled -->
<ssl_cert_file>/path/to/ssl_cert_file</ssl_cert_file>
<ssl_key_file>/path/to/ssl_key_file</ssl_key_file>
<!-- Whether server requests client for a certificate -->
<ssl_require_client_auth>false</ssl_require_client_auth>
<!-- The following file is used only if ssl_require_client_auth=true -->
<ssl_ca_cert_file>/path/to/ssl_ca_cert_file</ssl_ca_cert_file>
<!-- Default compression algorithm (applied if client doesn't specify another algorithm, see result_compression in QueryInfo).
Supported algorithms: none, deflate, gzip, stream_gzip -->
<compression>deflate</compression>
<!-- Default compression level (applied if client doesn't specify another level, see result_compression in QueryInfo).
Supported levels: none, low, medium, high -->
<compression_level>medium</compression_level>
<!-- Send/receive message size limits in bytes. -1 means unlimited -->
<max_send_message_size>-1</max_send_message_size>
<max_receive_message_size>-1</max_receive_message_size>
<!-- Enable if you want to get detailed logs -->
<verbose_logs>false</verbose_logs>
</grpc>
```
## Built-in Client {#grpc-client}
You can write a client in any of the programming languages supported by gRPC using the provided [specification](https://github.com/ClickHouse/ClickHouse/blob/master/src/Server/grpc_protos/clickhouse_grpc.proto).
Or you can use a built-in Python client. It is placed in [utils/grpc-client/clickhouse-grpc-client.py](https://github.com/ClickHouse/ClickHouse/blob/master/utils/grpc-client/clickhouse-grpc-client.py) in the repository. The built-in client requires [grpcio and grpcio-tools](https://grpc.io/docs/languages/python/quickstart) Python modules.
The client supports the following arguments:
- `--help` – Shows a help message and exits.
- `--host HOST, -h HOST` – A server name. Default value: `localhost`. You can use IPv4 or IPv6 addresses also.
- `--port PORT` – A port to connect to. This port should be enabled in the ClickHouse server configuration (see `grpc_port`). Default value: `9100`.
- `--user USER_NAME, -u USER_NAME` – A user name. Default value: `default`.
- `--password PASSWORD` – A password. Default value: empty string.
- `--query QUERY, -q QUERY` – A query to process when using non-interactive mode.
- `--database DATABASE, -d DATABASE` – A default database. If not specified, the current database set in the server settings is used (`default` by default).
- `--format OUTPUT_FORMAT, -f OUTPUT_FORMAT` – A result output [format](formats.md). Default value for interactive mode: `PrettyCompact`.
- `--debug` – Enables showing debug information.
To run the client in an interactive mode call it without `--query` argument.
In a batch mode query data can be passed via `stdin`.
**Client Usage Example**
In the following example a table is created and loaded with data from a CSV file. Then the content of the table is queried.
``` bash
./clickhouse-grpc-client.py -q "CREATE TABLE grpc_example_table (id UInt32, text String) ENGINE = MergeTree() ORDER BY id;"
echo "0,Input data for" > a.txt ; echo "1,gRPC protocol example" >> a.txt
cat a.txt | ./clickhouse-grpc-client.py -q "INSERT INTO grpc_example_table FORMAT CSV"
./clickhouse-grpc-client.py --format PrettyCompact -q "SELECT * FROM grpc_example_table;"
```
Result:
``` text
┌─id─┬─text──────────────────┐
│ 0 │ Input data for │
│ 1 │ gRPC protocol example │
└────┴───────────────────────┘
```

# sparkbar {#sparkbar}
The function plots a frequency histogram for values `x` and the repetition rate `y` of these values over the interval `[min_x, max_x]`.
If no interval is specified, then the minimum `x` is used as the interval start, and the maximum `x` — as the interval end.
**Syntax**
``` sql
sparkbar(width[, min_x, max_x])(x, y)
```
**Parameters**
- `width` — The number of segments. Type: [Integer](../../../sql-reference/data-types/int-uint.md).
- `min_x` — The interval start. Optional parameter.
- `max_x` — The interval end. Optional parameter.
**Arguments**
- `x` — The field with values.
- `y` — The field with the frequency of values.
**Returned value**
- The frequency histogram.
**Example**
Query:
``` sql
CREATE TABLE spark_bar_data (`cnt` UInt64,`event_date` Date) ENGINE = MergeTree ORDER BY event_date SETTINGS index_granularity = 8192;
INSERT INTO spark_bar_data VALUES(1,'2020-01-01'),(4,'2020-01-02'),(5,'2020-01-03'),(2,'2020-01-04'),(3,'2020-01-05'),(7,'2020-01-06'),(6,'2020-01-07'),(8,'2020-01-08'),(2,'2020-01-11');

# Time Window Functions {#time-window-functions}
Time window functions return the inclusive lower and exclusive upper bound of the corresponding window. The functions for working with WindowView are listed below:
## tumble {#time-window-functions-tumble}
A tumbling time window assigns records to non-overlapping, continuous windows with a fixed duration (`interval`).
``` sql
tumble(time_attr, interval [, timezone])
```
**Arguments**
- `time_attr` - Date and time. [DateTime](../../sql-reference/data-types/datetime.md) data type.
- `interval` - Window interval in [Interval](../../sql-reference/data-types/special-data-types/interval.md) data type.
- `timezone` — [Timezone name](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) (optional).
**Returned values**
- The inclusive lower and exclusive upper bound of the corresponding tumbling window.
Type: `Tuple(DateTime, DateTime)`
**Example**
Query:
``` sql
SELECT tumble(now(), toIntervalDay('1'))
```
Result:
``` text
┌─tumble(now(), toIntervalDay('1'))─────────────┐
│ ['2020-01-01 00:00:00','2020-01-02 00:00:00'] │
└───────────────────────────────────────────────┘
```
## hop {#time-window-functions-hop}
A hopping time window has a fixed duration (`window_interval`) and hops by a specified hop interval (`hop_interval`). If the `hop_interval` is smaller than the `window_interval`, hopping windows are overlapping. Thus, records can be assigned to multiple windows.
``` sql
hop(time_attr, hop_interval, window_interval [, timezone])
```
**Arguments**
- `time_attr` - Date and time. [DateTime](../../sql-reference/data-types/datetime.md) data type.
- `hop_interval` - Hop interval in [Interval](../../sql-reference/data-types/special-data-types/interval.md) data type. Should be a positive number.
- `window_interval` - Window interval in [Interval](../../sql-reference/data-types/special-data-types/interval.md) data type. Should be a positive number.
- `timezone` — [Timezone name](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) (optional).
**Returned values**
- The inclusive lower and exclusive upper bound of the corresponding hopping window. Since one record can be assigned to multiple hop windows, the function only returns the bound of the **first** window when hop function is used **without** `WINDOW VIEW`.
Type: `Tuple(DateTime, DateTime)`
**Example**
Query:
``` sql
SELECT hop(now(), INTERVAL '1' SECOND, INTERVAL '2' SECOND)
```
Result:
``` text
┌─hop(now(), toIntervalSecond('1'), toIntervalSecond('2'))──┐
│ ('2020-01-14 16:58:22','2020-01-14 16:58:24') │
└───────────────────────────────────────────────────────────┘
```
## tumbleStart {#time-window-functions-tumblestart}
Returns the inclusive lower bound of the corresponding tumbling window.
``` sql
tumbleStart(time_attr, interval [, timezone]);
```
## tumbleEnd {#time-window-functions-tumbleend}
Returns the exclusive upper bound of the corresponding tumbling window.
``` sql
tumbleEnd(time_attr, interval [, timezone]);
```
## hopStart {#time-window-functions-hopstart}
Returns the inclusive lower bound of the corresponding hopping window.
``` sql
hopStart(time_attr, hop_interval, window_interval [, timezone]);
```
## hopEnd {#time-window-functions-hopend}
Returns the exclusive upper bound of the corresponding hopping window.
``` sql

!!! important "Important"
This is an experimental feature that may change in backwards-incompatible ways in the future releases.
Enable usage of window views and `WATCH` query using [allow_experimental_window_view](../../../operations/settings/settings.md#allow-experimental-window-view) setting. Input the command `set allow_experimental_window_view = 1`.
``` sql
CREATE WINDOW VIEW [IF NOT EXISTS] [db.]table_name [TO [db.]table_name] [ENGINE = engine] [WATERMARK = strategy] [ALLOWED_LATENESS = interval_function] AS SELECT ... GROUP BY time_window_function
```
Window view can aggregate data by time window and output the results when the window is ready to fire. It stores the partial aggregation results in an inner(or specified) table to reduce latency and can push the processing result to a specified table or push notifications using the WATCH query.
Creating a window view is similar to creating `MATERIALIZED VIEW`. Window view needs an inner storage engine to store intermediate data. The inner storage will use `AggregatingMergeTree` as the default engine.
### Time Window Functions {#window-view-timewindowfunctions}
[Time window functions](../../functions/time-window-functions.md) are used to get the lower and upper window bound of records. The window view needs to be used with a time window function.
### TIME ATTRIBUTES {#window-view-timeattributes}
Window view supports **processing time** and **event time** process.
**Processing time** allows window view to produce results based on the local machine's time and is used by default. It is the most straightforward notion of time but does not provide determinism. The processing time attribute can be defined by setting the `time_attr` of the time window function to a table column or using the function `now()`. The following query creates a window view with processing time.
``` sql
CREATE WINDOW VIEW wv AS SELECT count(number), tumbleStart(w_id) as w_start from date GROUP BY tumble(now(), INTERVAL '5' SECOND) as w_id
```
**Event time** is the time that each individual event occurred on its producing device. This time is typically embedded within the records when it is generated. Event time processing allows for consistent results even in case of out-of-order events or late events. Window view supports event time processing by using `WATERMARK` syntax.
Window view provides three watermark strategies:
* `STRICTLY_ASCENDING`: Emits a watermark of the maximum observed timestamp so far. Rows that have a timestamp smaller to the max timestamp are not late.
* `ASCENDING`: Emits a watermark of the maximum observed timestamp so far minus 1. Rows that have a timestamp equal and smaller to the max timestamp are not late.
* `BOUNDED`: WATERMARK=INTERVAL. Emits watermarks, which are the maximum observed timestamp minus the specified delay.
The following queries are examples of creating a window view with `WATERMARK`:
``` sql
CREATE WINDOW VIEW wv WATERMARK=STRICTLY_ASCENDING AS SELECT count(number) FROM date GROUP BY tumble(timestamp, INTERVAL '5' SECOND);
CREATE WINDOW VIEW wv WATERMARK=ASCENDING AS SELECT count(number) FROM date GROUP BY tumble(timestamp, INTERVAL '5' SECOND);
CREATE WINDOW VIEW wv WATERMARK=INTERVAL '3' SECOND AS SELECT count(number) FROM date GROUP BY tumble(timestamp, INTERVAL '5' SECOND);
```
By default, the window will be fired when the watermark comes, and elements that arrived behind the watermark will be dropped. Window view supports late event processing by setting `ALLOWED_LATENESS=INTERVAL`. An example of lateness handling is:
``` sql
CREATE WINDOW VIEW test.wv TO test.dst WATERMARK=ASCENDING ALLOWED_LATENESS=INTERVAL '2' SECOND AS SELECT count(a) AS count, tumbleEnd(wid) AS w_end FROM test.mt GROUP BY tumble(timestamp, INTERVAL '5' SECOND) AS wid;
```
Note that elements emitted by a late firing should be treated as updated results of a previous computation. Instead of firing at the end of windows, the window view will fire immediately when the late event arrives. Thus, it will result in multiple outputs for the same window. Users need to take these duplicated results into account or deduplicate them.
### Monitoring New Windows {#window-view-monitoring}
Window view supports the `WATCH` query to constantly append the processing results to the console or use `TO` syntax to output the results to a table.
``` sql
WATCH [db.]name [LIMIT n]
```
`WATCH` query acts similar as in `LIVE VIEW`. A `LIMIT` can be specified to set the number of updates to receive before terminating the query.
### Settings {#window-view-settings}
- `window_view_clean_interval`: The clean interval of window view in seconds to free outdated data. The system will retain the windows that have not been fully triggered according to the system time or `WATERMARK` configuration, and the other data will be deleted.
- `window_view_heartbeat_interval`: The heartbeat interval in seconds to indicate the watch query is alive.
### Example {#window-view-example}
Suppose we need to count the number of click logs per 10 seconds in a log table called `data`, and its table structure is:
``` sql
CREATE TABLE data ( `id` UInt64, `timestamp` DateTime) ENGINE = Memory;
```
First, we create a window view with tumble window of 10 seconds interval:
``` sql
CREATE WINDOW VIEW wv as select count(id), tumbleStart(w_id) as window_start from data group by tumble(timestamp, INTERVAL '10' SECOND) as w_id
```
Then, we use the `WATCH` query to get the results.
``` sql
WATCH wv
```
When logs are inserted into table `data`,
``` sql
INSERT INTO data VALUES(1,now())
```
The `WATCH` query should print the results as follows:
``` text
┌─count(id)─┬────────window_start─┐
│ 1 │ 2020-01-14 16:56:40 │
└───────────┴─────────────────────┘
```
Alternatively, we can attach the output to another table using `TO` syntax.
``` sql
CREATE WINDOW VIEW wv TO dst AS SELECT count(id), tumbleStart(w_id) as window_start FROM data GROUP BY tumble(timestamp, INTERVAL '10' SECOND) as w_id
```
Additional examples can be found among stateful tests of ClickHouse (they are named `*window_view*` there).
### Window View Usage {#window-view-usage}
The window view is useful in the following scenarios:
* **Monitoring**: Aggregate and calculate the metrics logs by time, and output the results to a target table. The dashboard can use the target table as a source table.
* **Analyzing**: Automatically aggregate and preprocess data in the time window. This can be useful when analyzing a large number of logs. The preprocessing eliminates repeated calculations in multiple queries and reduces query latency.

# Интерфейс gRPC {#grpc-interface}
## Введение {#grpc-interface-introduction}
ClickHouse поддерживает интерфейс [gRPC](https://grpc.io/). Это система удаленного вызова процедур с открытым исходным кодом, которая использует HTTP/2 и [Protocol Buffers](https://ru.wikipedia.org/wiki/Protocol_Buffers). В реализации gRPC в ClickHouse поддерживаются:
- SSL;
- аутентификация;
- сессии;
- сжатие;
- параллельные запросы, выполняемые через один канал;
- отмена запросов;
- получение прогресса операций и логов;
- внешние таблицы.
Спецификация интерфейса содержится в [clickhouse_grpc.proto](https://github.com/ClickHouse/ClickHouse/blob/master/src/Server/grpc_protos/clickhouse_grpc.proto).
## Конфигурация gRPC {#grpc-interface-configuration}
Чтобы сделать доступным интерфейс gRPC, нужно задать порт с помощью настройки `grpc_port` в [конфигурации сервера](../operations/configuration-files.md). Другие настройки приведены в примере:
```xml
<grpc_port>9100</grpc_port>
<grpc>
<enable_ssl>false</enable_ssl>
<!-- Пути к файлам сертификатов и ключей. Используются при включенном SSL -->
<ssl_cert_file>/path/to/ssl_cert_file</ssl_cert_file>
<ssl_key_file>/path/to/ssl_key_file</ssl_key_file>
<!-- Запрашивает ли сервер сертификат клиента -->
<ssl_require_client_auth>false</ssl_require_client_auth>
<!-- Используется, если необходимо запрашивать сертификат -->
<ssl_ca_cert_file>/path/to/ssl_ca_cert_file</ssl_ca_cert_file>
<!-- Алгоритм сжатия по умолчанию (применяется, если клиент не указывает алгоритм, см. result_compression в QueryInfo).
Поддерживаются алгоритмы: none, deflate, gzip, stream_gzip -->
<compression>deflate</compression>
<!-- Уровень сжатия по умолчанию (применяется, если клиент не указывает уровень сжатия, см. result_compression в QueryInfo).
Поддерживаемые уровни: none, low, medium, high -->
<compression_level>medium</compression_level>
<!-- Ограничение в байтах на размер отправляемых и принимаемых сообщений. -1 означает отсутствие ограничения -->
<max_send_message_size>-1</max_send_message_size>
<max_receive_message_size>-1</max_receive_message_size>
<!-- Выводить ли детализированные логи -->
<verbose_logs>false</verbose_logs>
</grpc>
```
## Встроенный клиент {#grpc-client}
Можно написать клиент на любом языке программирования, который поддерживается gRPC, с использованием [спецификации](https://github.com/ClickHouse/ClickHouse/blob/master/src/Server/grpc_protos/clickhouse_grpc.proto).
Также можно воспользоваться встроенным Python клиентом. Он расположен в [utils/grpc-client/clickhouse-grpc-client.py](https://github.com/ClickHouse/ClickHouse/blob/master/utils/grpc-client/clickhouse-grpc-client.py) в репозитории. Для работы встроенного клиента требуются Python модули [grpcio и grpcio-tools](https://grpc.io/docs/languages/python/quickstart).
Клиент поддерживает аргументы:
- `--help` – вывести справку и завершить работу.
- `--host HOST, -h HOST` – имя сервера. Значение по умолчанию: `localhost`. Можно задать адрес IPv4 или IPv6.
- `--port PORT` – номер порта. Этот порт должен быть задан в конфигурации сервера ClickHouse настройкой `grpc_port`. Значение по умолчанию: `9100`.
- `--user USER_NAME, -u USER_NAME` – имя пользователя. Значение по умолчанию: `default`.
- `--password PASSWORD` – пароль. Значение по умолчанию: пустая строка.
- `--query QUERY, -q QUERY` – запрос, который выполнится, когда используется неинтерактивный режим работы.
- `--database DATABASE, -d DATABASE` – база данных по умолчанию. Если не указана, то будет использована база данных, заданная в настройках сервера (по умолчанию `default`).
- `--format OUTPUT_FORMAT, -f OUTPUT_FORMAT` – [формат](formats.md) вывода результата. Значение по умолчанию для интерактивного режима: `PrettyCompact`.
- `--debug` – вывод отладочной информации.
Чтобы запустить клиент в интерактивном режиме, не указывайте аргумент `--query`.
В неинтерактивном режиме данные запроса можно передать через `stdin`.
**Пример использования клиента**
В примере создается таблица, и в нее загружаются данные из CSV файла. Затем выводится содержимое таблицы.
``` bash
./clickhouse-grpc-client.py -q "CREATE TABLE grpc_example_table (id UInt32, text String) ENGINE = MergeTree() ORDER BY id;"
echo "0,Input data for" > a.txt ; echo "1,gRPC protocol example" >> a.txt
cat a.txt | ./clickhouse-grpc-client.py -q "INSERT INTO grpc_example_table FORMAT CSV"
./clickhouse-grpc-client.py --format PrettyCompact -q "SELECT * FROM grpc_example_table;"
```
Результат:
``` text

│ 0 │ Input data for │
│ 1 │ gRPC protocol example │

# system.query_views_log {#system_tables-query_views_log}
Содержит информацию о зависимых представлениях, выполняемых при выполнении запроса, например, тип представления или время выполнения.
Чтобы начать ведение журнала:
1. Настройте параметры в разделе [query_views_log](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-query_views_log).
2. Включите настройку [log_query_views=1](../../operations/settings/settings.md#settings-log-query-views).
Период сброса данных из буфера в памяти задается в параметре `flush_interval_milliseconds` в разделе настроек сервера [query_views_log](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-query_views_log ). Для принудительного сброса используйте запрос [SYSTEM FLUSH LOGS](../../sql-reference/statements/system.md#query_language-system-flush_logs).
ClickHouse не удаляет данные из таблицы автоматически. Подробнее смотрите раздел [Системные таблицы](../../operations/system-tables/index.md#system-tables-introduction).

# 时间窗口函数 {#time-window-han-shu}
时间窗口函数用于获取窗口的起始(包含边界)和结束时间(不包含边界)。系统支持的时间窗口函数如下：
## tumble {#time-window-functions-tumble}
tumble窗口是连续的、不重叠的固定大小(`interval`)时间窗口。
``` sql
tumble(time_attr, interval [, timezone])
```
**参数**
- `time_attr` - [DateTime](../../sql-reference/data-types/datetime.md)类型的时间数据。
- `interval` - [Interval](../../sql-reference/data-types/special-data-types/interval.md)类型的窗口大小。
- `timezone` — [Timezone name](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) 类型的时区(可选参数).
**返回值**
- tumble窗口的开始(包含边界)和结束时间(不包含边界)
类型: `Tuple(DateTime, DateTime)`
**示例**
查询：
``` sql
SELECT tumble(now(), toIntervalDay('1'))
```
结果：
``` text
┌─tumble(now(), toIntervalDay('1'))─────────────┐
│ ['2020-01-01 00:00:00','2020-01-02 00:00:00'] │
└───────────────────────────────────────────────┘
```
## hop {#time-window-functions-hop}
hop窗口是一个固定大小(`window_interval`)的时间窗口，并按照一个固定的滑动间隔(`hop_interval`)滑动。当滑动间隔小于窗口大小时，滑动窗口间存在重叠，此时一个数据可能存在于多个窗口。
``` sql
hop(time_attr, hop_interval, window_interval [, timezone])
```
**参数**
- `time_attr` - [DateTime](../../sql-reference/data-types/datetime.md)类型的时间数据。
- `hop_interval` - [Interval](../../sql-reference/data-types/special-data-types/interval.md)类型的滑动间隔，需要大于0。
- `window_interval` - [Interval](../../sql-reference/data-types/special-data-types/interval.md)类型的窗口大小，需要大于0。
- `timezone` — [Timezone name](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) 类型的时区(可选参数)。
**返回值**
- hop窗口的开始(包含边界)和结束时间(不包含边界)。由于一个数据可能存在于多个窗口，脱离window view单独调用该函数时只返回第一个窗口数据。
类型: `Tuple(DateTime, DateTime)`
**示例**
查询：
``` sql
SELECT hop(now(), INTERVAL '1' SECOND, INTERVAL '2' SECOND)
```
结果：

``` sql
tumbleStart(time_attr, interval [, timezone]);
```
## tumbleEnd {#time-window-functions-tumbleend}
返回tumble窗口的结束时间(不包含边界)。
``` sql
tumbleEnd(time_attr, interval [, timezone]);
```
## hopStart {#time-window-functions-hopstart}
返回hop窗口的开始时间(包含边界)。
``` sql
hopStart(time_attr, hop_interval, window_interval [, timezone]);

## Window View [Experimental] {#window-view}
!!! important "重要"
这是一项试验性功能，可能会在未来版本中以向后不兼容的方式进行更改。
通过[allow_experimental_window_view](../../../operations/settings/settings.md#allow-experimental-window-view)启用window view以及`WATCH`语句。输入命令
`set allow_experimental_window_view = 1`。
``` sql
CREATE WINDOW VIEW [IF NOT EXISTS] [db.]table_name [TO [db.]table_name] [ENGINE = engine] [WATERMARK = strategy] [ALLOWED_LATENESS = interval_function] AS SELECT ... GROUP BY time_window_function
```
Window view可以通过时间窗口聚合数据，并在满足窗口触发条件时自动触发对应窗口计算。其通过将计算状态保存降低处理延迟，支持将处理结果输出至目标表或通过`WATCH`语句输出至终端。
创建window view的方式和创建物化视图类似。Window view使用默认为`AggregatingMergeTree`的内部存储引擎存储计算中间状态。
### 时间窗口函数 {#window-view-shi-jian-chuang-kou-han-shu}
[时间窗口函数](../../functions/time-window-functions.md)用于获取窗口的起始和结束时间。Window view需要和时间窗口函数配合使用。
### 时间属性 {#window-view-shi-jian-shu-xing}
Window view 支持**处理时间**和**事件时间**两种时间类型。
**处理时间**为默认时间类型，该模式下window view使用本地机器时间计算窗口数据。“处理时间”时间类型计算简单，但具有不确定性。该模式下时间可以为时间窗口函数的第一个参数`time_attr`，或通过函数`now()`使用当前机器时间。下面的例子展示了使用“处理时间”创建window view的例子。
``` sql
CREATE WINDOW VIEW wv AS SELECT count(number), tumbleStart(w_id) as w_start from date GROUP BY tumble(now(), INTERVAL '5' SECOND) as w_id
```
**事件时间** 是事件真实发生的时间，该时间往往在事件发生时便嵌入数据记录。事件时间处理提供较高的确定性，可以处理乱序数据以及迟到数据。Window view通过水位线(`WATERMARK`)启用事件时间处理。
Window view提供如下三种水位线策略：
* `STRICTLY_ASCENDING`: 提交观测到的最大时间作为水位线，小于最大观测时间的数据不算迟到。
* `ASCENDING`: 提交观测到的最大时间减1作为水位线。小于或等于最大观测时间的数据不算迟到。
* `BOUNDED`: WATERMARK=INTERVAL. 提交最大观测时间减去固定间隔(`INTERVAL`)做为水位线。
以下为使用`WATERMARK`创建window view的示例：
``` sql
CREATE WINDOW VIEW wv WATERMARK=STRICTLY_ASCENDING AS SELECT count(number) FROM date GROUP BY tumble(timestamp, INTERVAL '5' SECOND);
CREATE WINDOW VIEW wv WATERMARK=ASCENDING AS SELECT count(number) FROM date GROUP BY tumble(timestamp, INTERVAL '5' SECOND);
CREATE WINDOW VIEW wv WATERMARK=INTERVAL '3' SECOND AS SELECT count(number) FROM date GROUP BY tumble(timestamp, INTERVAL '5' SECOND);
```
通常，窗口会在水位线到达时触发，水位线到达之后的数据会被丢弃。Window view可以通过设置`ALLOWED_LATENESS=INTERVAL`来开启迟到消息处理。示例如下：
``` sql
CREATE WINDOW VIEW test.wv TO test.dst WATERMARK=ASCENDING ALLOWED_LATENESS=INTERVAL '2' SECOND AS SELECT count(a) AS count, tumbleEnd(wid) AS w_end FROM test.mt GROUP BY tumble(timestamp, INTERVAL '5' SECOND) AS wid;
```
需要注意的是，迟到消息需要更新之前的处理结果。与在窗口结束时触发不同，迟到消息到达时window view会立即触发计算。因此，会导致同一个窗口输出多次计算结果。用户需要注意这种情况，并消除重复结果。
### 新窗口监控 {#window-view-xin-chuang-kou-jian-kong}
Window view可以通过`WATCH`语句将处理结果推送至终端，或通过`TO`语句将结果推送至数据表。
``` sql
WATCH [db.]name [LIMIT n]
```
`WATCH`语句和`LIVE VIEW`中的类似。支持设置`LIMIT`参数，输出消息数目达到`LIMIT`限制时结束查询。
### 设置 {#window-view-she-zhi}
- `window_view_clean_interval`: window view清除过期数据间隔(单位为秒)。系统会定期清除过期数据，尚未触发的窗口数据不会被清除。
- `window_view_heartbeat_interval`: 用于判断watch查询活跃的心跳时间间隔。
### 示例 {#window-view-shi-li}
假设我们需要每10秒统计一次`data`表中的点击日志，且`data`表的结构如下：
``` sql
CREATE TABLE data ( `id` UInt64, `timestamp` DateTime) ENGINE = Memory;
```
首先，使用10秒大小的tumble函数创建window view。
``` sql
CREATE WINDOW VIEW wv as select count(id), tumbleStart(w_id) as window_start from data group by tumble(timestamp, INTERVAL '10' SECOND) as w_id
```
随后，我们使用`WATCH`语句获取计算结果。
``` sql
WATCH wv
```
当日志插入表`data`时，
``` sql
INSERT INTO data VALUES(1,now())
```
`WATCH`语句会输出如下结果：
``` text
┌─count(id)─┬────────window_start─┐
│ 1 │ 2020-01-14 16:56:40 │
└───────────┴─────────────────────┘
```
或者，我们可以通过`TO`关键字将处理结果输出至另一张表。
``` sql
CREATE WINDOW VIEW wv TO dst AS SELECT count(id), tumbleStart(w_id) as window_start FROM data GROUP BY tumble(timestamp, INTERVAL '10' SECOND) as w_id
```
ClickHouse测试中提供了更多的示例(以`*window_view*`命名)。
### Window View 使用场景 {#window-view-shi-yong-chang-jing}
Window view 在以下场景有用：
* **监控**: 以时间维度聚合及处理数据，并将处理结果输出至目标表。用户可通过目标表获取并操作计算结果。
* **分析**: 以时间维度进行数据分析. 当数据源非常庞大时，window view可以减少重复全表查询的计算量。
