One checks the usual scenario where the instance's config specifies a `http_port`. In that case, we expect the `http_port` to be part of the response. The other scenario checks what happens when the config doesn't specify a `http_port`. It's hard to nail down the expectation there without hardcoding the error response (which is not what we generally want) but I'm mainly checking that no HTTP port is mentioned. This particular test would have failed before my previous fix, because the TCP handler wouldn't have managed to send back an HTTP response and `requests.post` would have thrown an exception. ---

 ## empty {#function-empty}
 
-Returns 1 for an empty array, or 0 for a non-empty array.
-The result type is UInt8.
-The function also works for strings.
+Checks whether the input array is empty.
 
-Can be optimized by enabling the [optimize_functions_to_subcolumns](../../operations/settings/settings.md#optimize-functions-to-subcolumns) setting. With `optimize_functions_to_subcolumns = 1` the function reads only [size0](../../sql-reference/data-types/array.md#array-size) subcolumn instead of reading and processing the whole array column. The query `SELECT empty(arr) FROM table` transforms to `SELECT arr.size0 = 0 FROM TABLE`.
+**Syntax**
+
+``` sql
+empty([x])
+```
+
+An array is considered empty if it contains all empty elements.

-Can be optimized by enabling the [optimize_functions_to_subcolumns](../../operations/settings/settings.md#optimize-functions-to-subcolumns) setting.

-### ClickHouse release v21.8.2.19-prestable FIXME!! as compared to v21.7.5.29-stable
+### ClickHouse release v21.8, 2021-08-11
 
 #### Backward Incompatible Changes
 
-* Use Map data type for system logs tables (`system.query_log`, `system.query_thread_log`, `system.processes`, `system.OpenTelemetrySpanLog`). These tables will be auto-created with new datatypes; old queries may be incompatible. [#23934](https://github.com/ClickHouse/ClickHouse/pull/23934) ([hexiaoting](https://github.com/hexiaoting)).
+* Use `Map` data type for system logs tables (`system.query_log`, `system.query_thread_log`, `system.processes`, `system.OpenTelemetrySpanLog`). These tables will be auto-created with new data types; old queries may be incompatible. [#23934](https://github.com/ClickHouse/ClickHouse/pull/23934) ([hexiaoting](https://github.com/hexiaoting)).
 
 #### New Features
 
 * Add new functions `leftPad()`, `rightPad()`, `leftPadUTF8()`, `rightPadUTF8()`. [#26075](https://github.com/ClickHouse/ClickHouse/pull/26075) ([Vitaly Baranov](https://github.com/vitlibar)).
 * Render pipelines as graphs in Web UI if `EXPLAIN PIPELINE graph = 1` query is submitted. [#26067](https://github.com/ClickHouse/ClickHouse/pull/26067) ([alexey-milovidov](https://github.com/alexey-milovidov)).
 * Add the `FIRST` keyword to the `ADD INDEX` command to be able to add the index at the beginning of the indices list. [#25904](https://github.com/ClickHouse/ClickHouse/pull/25904) ([xjewer](https://github.com/xjewer)).
-* Introduce `system.data_skipping_indices` table containing information about existing data skipping indices. This closes [#7659](https://github.com/ClickHouse/ClickHouse/issues/7659). [#25693](https://github.com/ClickHouse/ClickHouse/pull/25693) ([Dmitry Novik](https://github.com/novikd)).
+* Introduce `system.data_skipping_indices` table containing information about existing data skipping indices. Close [#7659](https://github.com/ClickHouse/ClickHouse/issues/7659). [#25693](https://github.com/ClickHouse/ClickHouse/pull/25693) ([Dmitry Novik](https://github.com/novikd)).
 * Add `bin`/`unbin` functions. [#25609](https://github.com/ClickHouse/ClickHouse/pull/25609) ([zhaoyu](https://github.com/zxc111)).

-* Collect common system metrics (in `system.asynchronous_metrics` and `system.asynchronous_metric_log`) on CPU usage, disk usage, memory usage, IO, network, files, load average, CPU frequencies, thermal sensors, EDAC counters, system uptime; also added metrics about the scheduling jitter and the time spent collecting the metrics. It works similar to `atop` in ClickHouse and allows access to monitoring data even if you have no additional tools installed. This closes [#9430](https://github.com/ClickHouse/ClickHouse/issues/9430). [#24416](https://github.com/ClickHouse/ClickHouse/pull/24416) ([Yegor Levankov](https://github.com/elevankoff)).

 #### New Features
 
+* Collect common system metrics (in `system.asynchronous_metrics` and `system.asynchronous_metric_log`) on CPU usage, disk usage, memory usage, IO, network, files, load average, CPU frequencies, thermal sensors, EDAC counters, system uptime; also added metrics about the scheduling jitter and the time spent collecting the metrics. It works similar to `atop` in ClickHouse and allows access to monitoring data even if you have no additional tools installed. Close [#9430](https://github.com/ClickHouse/ClickHouse/issues/9430). [#24416](https://github.com/ClickHouse/ClickHouse/pull/24416) ([Yegor Levankov](https://github.com/elevankoff)).

 ### ClickHouse release v21.8, 2021-08-11
 
-#### Backward Incompatible Changes
-
-* Use `Map` data type for system logs tables (`system.query_log`, `system.query_thread_log`, `system.processes`, `system.OpenTelemetrySpanLog`). These tables will be auto-created with new data types; old queries may be incompatible. [#23934](https://github.com/ClickHouse/ClickHouse/pull/23934) ([hexiaoting](https://github.com/hexiaoting)).
-
 #### New Features
 
 * Collect common system metrics (in `system.asynchronous_metrics` and `system.asynchronous_metric_log`) on CPU usage, disk usage, memory usage, IO, network, files, load average, CPU frequencies, thermal sensors, EDAC counters, system uptime; also added metrics about the scheduling jitter and the time spent collecting the metrics. It works similar to `atop` in ClickHouse and allows access to monitoring data even if you have no additional tools installed. Close [#9430](https://github.com/ClickHouse/ClickHouse/issues/9430).

+Note that the split build has several drawbacks:
+* There is no single `clickhouse` binary, and you have to run `clickhouse-server`, `clickhouse-client`, etc.
+* Risk of segfault if you run any of the programs while rebuilding the project.
+* You cannot run the integration tests since they only work a single complete binary.
+* You can't easily copy the binaries elsewhere. Instead of moving a single binary you'll need to copy all binaries and libraries.

+### Проекции {#projections}
+Проекции похожи на материализованные представления, но определяются на уровне партов. Это обеспечивает гарантии согласованности наряду с автоматическим использованием в запросах.
+
+#### Запрос {#projection-query}
+Запрос проекции - это то, что определяет проекцию. Он имеет следующую грамматику:
+
+`SELECT  [GROUP BY] [ORDER BY]`
+
+Это неявно выбирает данные из родительской таблицы.
+
+#### Хранение {#projection-storage}
+Проекции хранятся в каталоге парта. Это похоже на хранение индексов, но используется подкаталог, в котором хранится анонимный парт таблицы MergeTree. Таблица создается запросом определения проекции. Если есть конструкция GROUP BY, то базовый механизм хранения становится AggregatedMergeTree, а все агрегатные функции преобразуются в AggregateFunction. Если есть конструкция ORDER BY, таблица MergeTree будет использовать его в качестве выражения первичного ключа. Во время процесса слияния парт проекции будет слит с помощью процедуры слияния ее хранилища. Контрольная сумма парта родительской таблицы будет включать парт проекции. Другие процедуры аналогичны индексам пропуска данных.
+
+#### Анализ запросов {#projection-query-analysis}
+1. Проверить, можно ли использовать проекцию для результата на данный запрос, то есть она даёт тот же результат, что и запрос к базовой таблице.
+2. Выбрать наиболее подходящее совпадение, содержащее наименьшее количество гранул для чтения.
+3. План запроса, который использует проекции, будет отличаться от того, который использует исходные парты. Если в некоторых партах проекция отсутствует, мы можем расширить план, чтобы «проецировать» на лету.
+
 ## Конкурентный доступ к данным {#concurrent-data-access}
 
 Для конкурентного доступа к таблице используется мультиверсионность. То есть, при одновременном чтении и обновлении таблицы, данные будут читаться из набора кусочков, актуального на момент запроса. Длинных блокировок нет. Вставки никак не мешают чтениям.

 #### Хранение {#projection-storage}
 Проекции хранятся в каталоге парта. Это похоже на хранение индексов, но используется подкаталог, в котором хранится анонимный парт таблицы MergeTree. Таблица создается запросом определения проекции. Если есть конструкция GROUP BY, то базовый механизм хранения становится AggregatedMergeTree, а все агрегатные функции преобразуются в AggregateFunction. Если есть конструкция ORDER BY, таблица MergeTree будет использовать его в качестве выражения первичного ключа. Во время процесса слияния парт проекции будет слит с помощью процедуры слияния ее хранилища. Контрольная сумма парта родительской таблицы будет включать парт проекции. Другие процедуры аналогичны индексам пропуска данных.

 3. План запроса, который использует проекции, будет отличаться от того, который использует исходные парты. Если в некоторых партах проекция отсутствует, мы можем расширить план, чтобы «проецировать» на лету.

 #### New Features
 
-* Collect common system metrics (in `system.asynchronous_metrics` and `system.asynchronous_metric_log`) on CPU usage, disk usage, memory usage, IO, network, files, load average, CPU frequencies, thermal sensors, EDAC counters, system uptime; also added metrics about the scheduling jitter and the time spent collecting the metrics. It works similar to `atop` in ClickHouse and allows access to monitoring data even if you have no additional tools installed. Close [#9430](https://github.com/ClickHouse/ClickHouse/issues/9430). [#24416](https://github.com/ClickHouse/ClickHouse/pull/24416) ([Yegor Levankov](https://github.com/elevankoff)).

 #### New Features
 
-* Add support for a part of SQL/JSON standard. [#24148](https://github.com/ClickHouse/ClickHouse/pull/24148) ([l1tsolaiki](https://github.com/l1tsolaiki)).
-* Collect common system metrics (in `system.asynchronous_metrics` and `system.asynchronous_metric_log`) on CPU usage, disk usage, memory usage, IO, network, files, load average, CPU frequencies, thermal sensors, EDAC counters, system uptime; also added metrics about the scheduling jitter and the time spent collecting the metrics. It works similar to `atop` in ClickHouse and allows access to monitoring data even if you have no additional tools installed. Close [#9430](https://github.com/ClickHouse/ClickHouse/issues/9430).
