 #### Backward Incompatible Change
+
 * Extended range of `Date32` and `DateTime64` to support dates from the year 1900 to 2299. In previous versions, the supported interval was only from the year 1925 to 2283. The implementation is using the proleptic Gregorian calendar (which is conformant with [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601):2004 (clause 3.2.1 The Gregorian calendar)) instead of accounting for historical transitions from the Julian to the Gregorian calendar. This change affects implementation-specific behavior for out-of-range arguments. E.g. if in previous versions the value of `1899-01-01` was clamped to `1925-01-01`, in the new version it will be clamped to `1900-01-01`. It changes the behavior of rounding with `toStartOfInterval` if you pass `INTERVAL 3 QUARTER` up to one quarter because the intervals are counted from an implementation-specific point of time. Closes [#28216](https://github.com/ClickHouse/ClickHouse/issues/28216), improves [#38393](https://github.com/ClickHouse/ClickHouse/issues/38393). [#39425](https://github.com/ClickHouse/ClickHouse/pull/39425) ([Roman Vasin](https://github.com/rvasin)).
 * Now, all relevant dictionary sources respect `remote_url_allow_hosts` setting. It was already done for HTTP, Cassandra, Redis. Added ClickHouse, MongoDB, MySQL, PostgreSQL. Host is checked only for dictionaries created from DDL. [#39184](https://github.com/ClickHouse/ClickHouse/pull/39184) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
 * Make the remote filesystem cache composable, allow not to evict certain files (regarding idx, mrk, ..), delete old cache version. Now it is possible to configure cache over Azure blob storage disk, over Local disk, over StaticWeb disk, etc. This PR is marked backward incompatible because cache configuration changes and in order for cache to work need to update the config file. Old cache will still be used with new configuration. The server will startup fine with the old cache configuration. Closes https://github.com/ClickHouse/ClickHouse/issues/36140. Closes https://github.com/ClickHouse/ClickHouse/issues/37889. ([Kseniia Sumarokova](https://github.com/kssenii)). [#36171](https://github.com/ClickHouse/ClickHouse/pull/36171))

 * Added a setting `exact_rows_before_limit` (0/1). When enabled, ClickHouse will provide exact value for `rows_before_limit_at_least` statistic, but with the cost that the data before limit will have to be read completely. This closes [#6613](https://github.com/ClickHouse/ClickHouse/issues/6613). [#25333](https://github.com/ClickHouse/ClickHouse/pull/25333) ([kevin wan](https://github.com/MaxWk)).

 #### Performance Improvement
+
 * Improved memory usage during memory efficient merging of aggregation results. [#39429](https://github.com/ClickHouse/ClickHouse/pull/39429) ([Nikita Taranov](https://github.com/nickitat)).
 * Added concurrency control logic to limit total number of concurrent threads created by queries. [#37558](https://github.com/ClickHouse/ClickHouse/pull/37558) ([Sergei Trifonov](https://github.com/serxa)).

 * Intel® In-Memory Analytics Accelerator (Intel® IAA) is a hardware accelerator available in the upcoming generation of Intel® Xeon® Scalable processors ("Sapphire Rapids"). Its goal is to speed up common operations in analytics like data (de)compression and filtering. ClickHouse gained the new "DeflateQpl" compression codec which utilizes the Intel® IAA offloading technology to provide a high-performance DEFLATE implementation. The codec uses the [Intel® Query Processing Library (QPL)](https://github.com/intel/qpl) which abstracts access to the hardware accelerator, respectively to a software fallback in case the hardware accelerator is not available. DEFLATE provides in general higher compression rates than ClickHouse's LZ4 default codec, and as a result, offers less disk I/O and lower main memory consumption. [#36654](https://github.com/ClickHouse/ClickHouse/pull/36654) ([jasperzhu](https://github.com/jinjunzh)). [#39494](https://github.com/ClickHouse/ClickHouse/pull/39494) ([Robert Schulze](https://github.com/rschu1ze)).
 * `DISTINCT` in order with `ORDER BY`: Deduce way to sort based on input stream sort description. Skip sorting if input stream is already sorted. [#38719](https://github.com/ClickHouse/ClickHouse/pull/38719) ([Igor Nikonov](https://github.com/devcrafter)). Improve memory usage (significantly) and query execution time + use `DistinctSortedChunkTransform` for final distinct when `DISTINCT` columns match `ORDER BY` columns, but rename to `DistinctSortedStreamTransform` in `EXPLAIN PIPELINE` → this improves memory usage significantly + remove unnecessary allocations in hot loop in `DistinctSortedChunkTransform`. [#39432](https://github.com/ClickHouse/ClickHouse/pull/39432) ([Igor Nikonov](https://github.com/devcrafter)). Use `DistinctSortedTransform` only when sort description is applicable to DISTINCT columns, otherwise fall back to ordinary DISTINCT implementation + it allows making less checks during `DistinctSortedTransform` execution. [#39528](https://github.com/ClickHouse/ClickHouse/pull/39528) ([Igor Nikonov](https://github.com/devcrafter)). Fix: `DistinctSortedTransform` didn't take advantage of sorting. It never cleared HashSet since clearing_columns were detected incorrectly (always empty). So, it basically worked as ordinary `DISTINCT` (`DistinctTransform`). The fix reduces memory usage significantly. [#39538](https://github.com/ClickHouse/ClickHouse/pull/39538) ([Igor Nikonov](https://github.com/devcrafter)).

 #### Improvement
+
 * Normalize `AggregateFunction` types and state representations because optimizations like [#35788](https://github.com/ClickHouse/ClickHouse/pull/35788) will treat `count(not null columns)` as `count()`, which might confuses distributed interpreters with the following error : `Conversion from AggregateFunction(count) to AggregateFunction(count, Int64) is not supported`. [#39420](https://github.com/ClickHouse/ClickHouse/pull/39420) ([Amos Bird](https://github.com/amosbird)). The functions with identical states can be used in materialized views interchangeably.
 * Rework and simplify the `system.backups` table, remove the `internal` column, allow user to set the ID of operation, add columns `num_files`, `uncompressed_size`, `compressed_size`, `start_time`, `end_time`. [#39503](https://github.com/ClickHouse/ClickHouse/pull/39503) ([Vitaly Baranov](https://github.com/vitlibar)).
 * Improved structure of DDL query result table for `Replicated` database (separate columns with shard and replica name, more clear status) - `CREATE TABLE ... ON CLUSTER` queries can be normalized on initiator first if `distributed_ddl_entry_format_version` is set to 3 (default value). It means that `ON CLUSTER` queries may not work if initiator does not belong to the cluster that specified in query.

+
 * Enable setting `enable_positional_arguments` by default. It allows queries like `SELECT ... ORDER BY 1, 2` where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. [#38204](https://github.com/ClickHouse/ClickHouse/pull/38204) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
 * Disable `format_csv_allow_single_quotes` by default. See [#37096](https://github.com/ClickHouse/ClickHouse/issues/37096). ([Kruglov Pavel](https://github.com/Avogar)).
 * `Ordinary` database engine and old storage definition syntax for `*MergeTree` tables are deprecated. By default it's not possible to create new databases with `Ordinary` engine. If `system` database has `Ordinary` engine it will be automatically converted to `Atomic` on server startup. There are settings to keep old behavior (`allow_deprecated_database_ordinary` and `allow_deprecated_syntax_for_merge_tree`), but these settings may be removed in future releases. [#38335](https://github.com/ClickHouse/ClickHouse/pull/38335) ([Alexander Tokmakov](https://github.com/tavplubix)).

 * If you run different ClickHouse versions on a cluster with AArch64 CPU or mix AArch64 and amd64 on a cluster, and use distributed queries with GROUP BY multiple keys of fixed-size type that fit in 256 bits but don't fit in 64 bits, and the size of the result is huge, the data will not be fully aggregated in the result of these queries during upgrade. Workaround: upgrade with downtime instead of a rolling upgrade.
 
 #### New Feature
+

 #### Performance Improvement
+
 * Added numerous optimizations for ARM NEON [#38093](https://github.com/ClickHouse/ClickHouse/pull/38093)([Daniel Kutenin](https://github.com/danlark1)), ([Alexandra Pilipyuk](https://github.com/chalice19)) Note: if you run different ClickHouse versions on a cluster with ARM CPU and use distributed queries with GROUP BY multiple keys of fixed-size type that fit in 256 bits but don't fit in 64 bits, the result of the aggregation query will be wrong during upgrade. Workaround: upgrade with downtime instead of a rolling upgrade.
 * Improve performance and memory usage for select of subset of columns for formats Native, Protobuf, CapnProto, JSONEachRow, TSKV, all formats with suffixes WithNames/WithNamesAndTypes. Previously while selecting only subset of columns from files in these formats all columns were read and stored in memory. Now only required columns are read.

@@ -49,27 +49,13 @@ When we calculate some function over columns in a block, we add another column w
 
 Blocks are created for every processed chunk of data. Note that for the same type of calculation, the column names and types remain the same for different blocks, and only column data changes. It is better to split block data from the block header because small block sizes have a high overhead of temporary strings for copying shared_ptrs and column names.
 
-## Block Streams {#block-streams}
+## Processors
 
-Block streams are for processing data. We use streams of blocks to read data from somewhere, perform data transformations, or write data to somewhere. `IBlockInputStream` has the `read` method to fetch the next block while available. `IBlockOutputStream` has the `write` method to push the block somewhere.
-
-Streams are responsible for:
-
-1.  Reading or writing to a table. The table just returns a stream for reading or writing blocks.
-2.  Implementing data formats. For example, if you want to output data to a terminal in `Pretty` format, you create a block output stream where you push blocks, and it formats them.
-3.  Performing data transformations. Let’s say you have `IBlockInputStream` and want to create a filtered stream. You create `FilterBlockInputStream` and initialize it with your stream. Then when you pull a block from `FilterBlockInputStream`, it pulls a block from your stream, filters it, and returns the filtered block to you. Query execution pipelines are represented this way.
-
-There are more sophisticated transformations. For example, when you pull from `AggregatingBlockInputStream`, it reads all data from its source, aggregates it, and then returns a stream of aggregated data for you. Another example: `UnionBlockInputStream` accepts many input sources in the constructor and also a number of threads. It launches multiple threads and reads from multiple sources in parallel.
-
-> Block streams use the “pull” approach to control flow: when you pull a block from the first stream, it consequently pulls the required blocks from nested streams, and the entire execution pipeline will work. Neither “pull” nor “push” is the best solution, because control flow is implicit, and that limits the implementation of various features like simultaneous execution of multiple queries (merging many pipelines together). This limitation could be overcome with coroutines or just running extra threads that wait for each other. We may have more possibilities if we make control flow explicit: if we locate the logic for passing data from one calculation unit to another outside of those calculation units. Read this [article](http://journal.stuffwithstuff.com/2013/01/13/iteration-inside-and-out/) for more thoughts.
-
-We should note that the query execution pipeline creates temporary data at each step. We try to keep block size small enough so that temporary data fits in the CPU cache. With that assumption, writing and reading temporary data is almost free in comparison with other calculations. We could consider an alternative, which is to fuse many operations in the pipeline together. It could make the pipeline as short as possible and remove much of the temporary data, which could be an advantage, but it also has drawbacks. For example, a split pipeline makes it easy to implement caching intermediate data, stealing intermediate data from similar queries running at the same time, and merging pipelines for similar queries.
+See the description at [https://github.com/ClickHouse/ClickHouse/blob/master/src/Processors/IProcessor.h](https://github.com/ClickHouse/ClickHouse/blob/master/src/Processors/IProcessor.h).
 
 ## Formats {#formats}
 
-Data formats are implemented with block streams. There are “presentational” formats only suitable for the output of data to the client, such as `Pretty` format, which provides only `IBlockOutputStream`. And there are input/output formats, such as `TabSeparated` or `JSONEachRow`.
-
-There are also row streams: `IRowInputStream` and `IRowOutputStream`. They allow you to pull/push data by individual rows, not by blocks. And they are only needed to simplify the implementation of row-oriented formats. The wrappers `BlockInputStreamFromRowInputStream` and `BlockOutputStreamFromRowOutputStream` allow you to convert row-oriented streams to regular block-oriented streams.
+Data formats are implemented with processors.

+## Backup to S3
+
+It is possible to `BACKUP`/`RESTORE` to S3, but this disk should be configured
+in a proper way, since by default you will need to backup metadata from local
+disk to make backup full.
+
+First of all, you need to configure S3 disk in a special way:
+
+```xml
+<clickhouse>
+    <storage_configuration>
+        <disks>
+            <s3_plain>
+                <type>s3_plain</type>

+                <access_key_id></access_key_id>
+                <secret_access_key></secret_access_key>
+            </s3_plain>
+        </disks>
+        <policies>
+            <s3>
+                <volumes>
+                    <main>
+                        <disk>s3</disk>
+                    </main>
+                </volumes>
+            </s3>

+    </storage_configuration>
+
+    <backups>
+        <allowed_disk>s3_plain</allowed_disk>
+    </backups>
+</clickhouse>
+```
+
+And then `BACKUP`/`RESTORE` as usual:
+
+```sql
+BACKUP TABLE data TO Disk('s3_plain', 'cloud_backup');
+RESTORE TABLE data AS data_restored FROM Disk('s3_plain', 'cloud_backup');
+```
+

+1. 创建一个用于存储多边形的表：
+
+<Tabs groupId="deployMethod">
+<TabItem value="serverless" label="ClickHouse Cloud" default>
+
+```sql
+CREATE TABLE moscow (polygon Array(Tuple(Float64, Float64)))
+ORDER BY polygon;
+```
+

+<TabItem value="selfmanaged" label="Self-managed">
+
+```sql
+CREATE TEMPORARY TABLE
+moscow (polygon Array(Tuple(Float64, Float64)));
+```
+
+</TabItem>
+</Tabs>
+

-import Content from '@site/docs/en/getting-started/example-datasets/menus.md';
+该数据集由纽约公共图书馆创建。其中含有有关酒店、餐馆和咖啡馆的菜单上的菜肴及其价格的历史数据。
 
-<Content />
+来源：http://menus.nypl.org/data 
+数据为开放数据。
+
+数据来自于图书馆中的档案，因此可能不完整，以至于难以进行统计分析。尽管如此，该数据集也是非常有意思的。数据集中只有 130 万条关于菜单中的菜肴的记录 - 这对于 ClickHouse 来说是一个非常小的数据量，但这仍是一个很好的例子。
+
+## 下载数据集 {#download-dataset}
+
+运行命令：
+
+```bash
+wget https://s3.amazonaws.com/menusdata.nypl.org/gzips/2021_08_01_07_01_17_data.tgz
+```
+
+如果有需要可以使用 http://menus.nypl.org/data 中的最新链接。下载的大小约为 35 MB。
+
+## 解压数据集 {#unpack-dataset}
+
+```bash
+tar xvf 2021_08_01_07_01_17_data.tgz
+```
+
+解压后的的大小约为 150 MB。
+
+数据集由四个表组成： 
+
+- `Menu` - 有关菜单的信息，其中包含：餐厅名称，看到菜单的日期等 
+- `Dish` - 有关菜肴的信息，其中包含：菜肴名称以及一些特征。 
+- `MenuPage` - 有关菜单中页面的信息，每个页面都属于某个 `Menu`。 
+- `MenuItem` - 菜单项。某个菜单页面上的菜肴及其价格：指向 `Dish` 和 `MenuPage`的链接。
+
+## 创建表 {#create-tables}
+
+使用 [Decimal](/docs/zh/sql-reference/data-types/decimal.md) 数据类型来存储价格。
+
+```sql
+CREATE TABLE dish
+(
+    id UInt32,
+    name String,
+    description String,
+    menus_appeared UInt32,
+    times_appeared Int32,

+(
+    id UInt32,
+    name String,

+) ENGINE = MergeTree ORDER BY id;
+
+CREATE TABLE menu_item
+(
+    id UInt32,
+    menu_page_id UInt32,
+    price Decimal64(3),
+    high_price Decimal64(3),
+    dish_id UInt32,
+    created_at DateTime,
+    updated_at DateTime,
+    xpos Float64,
+    ypos Float64
+) ENGINE = MergeTree ORDER BY id;
+```
+
+## 导入数据 {#import-data}
+
+执行以下命令将数据导入 ClickHouse：
+
+```bash
+clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --query "INSERT INTO dish FORMAT CSVWithNames" < Dish.csv
+clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --query "INSERT INTO menu FORMAT CSVWithNames" < Menu.csv
+clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --query "INSERT INTO menu_page FORMAT CSVWithNames" < MenuPage.csv
+clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --date_time_input_format best_effort --query "INSERT INTO menu_item FORMAT CSVWithNames" < MenuItem.csv
+```
+
+因为数据由带有标题的 CSV 表示，所以使用 [CSVWithNames](/docs/zh/interfaces/formats.md#csvwithnames) 格式。
+
+因为只有双引号用于数据字段，单引号可以在值内，所以禁用了 `format_csv_allow_single_quotes` 以避免混淆 CSV 解析器。
+
+因为数据中没有 [NULL](/docs/zh/sql-reference/syntax.md#null-literal) 值，所以禁用 [input_format_null_as_default](/docs/zh/operations/settings/settings.md#settings-input-format-null-as-default)。不然 ClickHouse 将会尝试解析 `\N` 序列，并可能与数据中的 `\` 混淆。
+
+设置 [date_time_input_format best_effort](/docs/zh/operations/settings/settings.md#settings-date_time_input_format) 以便解析各种格式的 [DateTime](/docs/zh/sql-reference/data-types/datetime.md)字段。例如，识别像“2000-01-01 01:02”这样没有秒数的 ISO-8601 时间字符串。如果没有此设置，则仅允许使用固定的 DateTime 格式。
+
+## 非规范化数据 {#denormalize-data}
+
+数据以 [规范化形式] (https://en.wikipedia.org/wiki/Database_normalization#Normal_forms) 在多个表格中呈现。这意味着如果你想进行如查询菜单项中的菜名这类的查询，则必须执行 [JOIN](/docs/zh/sql-reference/statements/select/join.md#select-join)。在典型的分析任务中，预先处理联接的数据以避免每次都执行“联接”会更有效率。这中操作被称为“非规范化”数据。
+
+我们将创建一个表“menu_item_denorm”，其中将包含所有联接在一起的数据：
+
+```sql
+CREATE TABLE menu_item_denorm
+ENGINE = MergeTree ORDER BY (dish_name, created_at)
+AS SELECT
+    price,
+    high_price,

+## 下载数据集 {#download-dataset}
+
+运行命令：
+
+```bash
+wget -O- https://zenodo.org/record/5092942 | grep -oP 'https://zenodo.org/record/5092942/files/flightlist_\d+_\d+\.csv\.gz' | xargs wget
+```
+
+Download will take about 2 minutes with good internet connection. There are 30 files with total size of 4.3 GB.
+
+## 创建表 {#create-table}
+
+```sql
+CREATE TABLE opensky
+(
+    callsign String,
+    number String,
+    icao24 String,
+    registration String,
+    typecode String,
+    origin String,
+    destination String,
+    firstseen DateTime,
+    lastseen DateTime,
+    day DateTime,
+    latitude_1 Float64,
+    longitude_1 Float64,
+    altitude_1 Float64,
+    latitude_2 Float64,
+    longitude_2 Float64,
+    altitude_2 Float64
+) ENGINE = MergeTree ORDER BY (origin, destination, callsign);
+```
+
+## 导入数据 {#import-data}
+
+将数据并行导入到 ClickHouse：
+
+```bash
+ls -1 flightlist_*.csv.gz | xargs -P100 -I{} bash -c 'gzip -c -d "{}" | clickhouse-client --date_time_input_format best_effort --query "INSERT INTO opensky FORMAT CSVWithNames"'
+```
+
+- 这里我们将文件列表（`ls -1 flightlist_*.csv.gz`）传递给`xargs`以进行并行处理。 `xargs -P100` 指定最多使用 100 个并行工作程序，但由于我们只有 30 个文件，工作程序的数量将只有 30 个。 
+- 对于每个文件，`xargs` 将通过 `bash -c` 为每个文件运行一个脚本文件。该脚本通过使用 `{}` 表示文件名占位符，然后 `xargs` 由命令进行填充（使用 `-I{}`）。 
+- 该脚本会将文件 (`gzip -c -d "{}"`) 解压缩到标准输出（`-c` 参数），并将输出重定向到 `clickhouse-client`。 
+- 我们还要求使用扩展解析器解析 [DateTime](../../sql-reference/data-types/datetime.md) 字段 ([--date_time_input_format best_effort](../../operations/settings/ settings.md#settings-date_time_input_format)) 以识别具有时区偏移的 ISO-8601 格式。
+
+最后，`clickhouse-client` 会以 [CSVWithNames](../../interfaces/formats.md#csvwithnames) 格式读取输入数据然后执行插入。 
+
+并行导入需要 24 秒。
+
+如果您不想使用并行导入，以下是顺序导入的方式：
+
+```bash
+for file in flightlist_*.csv.gz; do gzip -c -d "$file" | clickhouse-client --date_time_input_format best_effort --query "INSERT INTO opensky FORMAT CSVWithNames"; done
+```

+
+这是一个展示如何解析自定义 CSV，这其中涉及了许多调整。
+
+说明： 
+- 数据集为 CSV 格式，但在插入时需要一些预处理；使用表函数 [input](../../sql-reference/table-functions/input.md) 进行预处理； 
+- CSV 文件的结构在表函数 `input` 的参数中指定； 
+- 字段 `num`（行号）是不需要的 - 可以忽略并从文件中进行解析； 
+- 使用 `FORMAT CSVWithNames`，因为标题不包含第一个字段的名称，因此 CSV 中的标题将被忽略（通过命令行参数 `--input_format_with_names_use_header 0`）； 
+- 文件仅使用双引号将 CSV 字符串括起来；一些字符串没有用双引号括起来，单引号也不能被解析为括起来的字符串 - 所以添加`--format_csv_allow_single_quote 0`参数接受文件中的单引号； 
+- 由于某些 CSV 的字符串的开头包含 `\M/` 因此无法被解析； CSV 中唯一可能以反斜杠开头的值是 `\N`，这个值被解析为 SQL NULL。通过添加`--input_format_allow_errors_num 10`参数，允许在导入过程中跳过 10 个格式错误； 
+- 在数据集中的 Ingredients、directions 和 NER 字段为数组；但这些数组并没有以一般形式表示：这些字段作为 JSON 序列化为字符串，然后放入 CSV 中 - 在导入是将它们解析为字符串，然后使用 [JSONExtract](../../sql-reference/functions/json-functions.md ) 函数将其转换为数组。

+
+请求：
+
+``` sql
+SELECT count() FROM recipes;
