+
+### ClickHouse release v22.8.5.29-lts (74ffb843807) FIXME as compared to v22.8.4.7-lts (baad27bcd2f)
+
+#### New Feature
+* Backported in [#40870](https://github.com/ClickHouse/ClickHouse/issues/40870): Add setting to disable limit on kafka_num_consumers. Closes [#40331](https://github.com/ClickHouse/ClickHouse/issues/40331). [#40670](https://github.com/ClickHouse/ClickHouse/pull/40670) ([Kruglov Pavel](https://github.com/Avogar)).
+
+#### Improvement
+* Backported in [#40817](https://github.com/ClickHouse/ClickHouse/issues/40817): The setting `show_addresses_in_stack_traces` was accidentally disabled in default `config.xml`. It's removed from the config now, so the setting is enabled by default. [#40749](https://github.com/ClickHouse/ClickHouse/pull/40749) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Backported in [#40944](https://github.com/ClickHouse/ClickHouse/issues/40944): Fix issue with passing MySQL timeouts for MySQL database engine and MySQL table function.

+
+* Backported in [#40866](https://github.com/ClickHouse/ClickHouse/issues/40866): - Fix crash while parsing values of type `Object` that contains arrays of variadic dimension. [#40483](https://github.com/ClickHouse/ClickHouse/pull/40483) ([Duc Canh Le](https://github.com/canhld94)).
+* Backported in [#40805](https://github.com/ClickHouse/ClickHouse/issues/40805): During insertion of a new query to the `ProcessList` allocations happen. If we reach the memory limit during these allocations we can not use `OvercommitTracker`, because `ProcessList::mutex` is already acquired. Fixes [#40611](https://github.com/ClickHouse/ClickHouse/issues/40611). [#40677](https://github.com/ClickHouse/ClickHouse/pull/40677) ([Dmitry Novik](https://github.com/novikd)).

+sidebar_label: NYPD Complaint Data
+description: "Ingest and query Tab Separated Value data in 5 steps"
+title: NYPD Complaint Data
+---
+
+Tab separated value, or TSV, files are common and may include field headings as the first line of the file. ClickHouse can ingest TSVs, and also can query TSVs without ingesting the files.  This guide covers both of these cases. If you need to query or ingest CSV files, the same techniques work, simply substitute `TSV` with `CSV` in your format arguments.
+
+While working through this guide you will:
+- **Investigate**: Query the structure and content of the TSV file.
+- **Determine the target ClickHouse schema**: Choose proper data types and map the existing data to those types.
+- **Create a ClickHouse table**.
+- **Preprocess and stream** the data to ClickHouse.
+- **Run some queries** against ClickHouse.
+
+The dataset used in this guide comes from the NYC Open Data team, and contains data about "all valid felony, misdemeanor, and violation crimes reported to the New York City Police Department (NYPD)". At the time of writing, the data file is 166MB, but it is updated regularly.
+
+**Source**: [data.cityofnewyork.us](https://data.cityofnewyork.us/Public-Safety/NYPD-Complaint-Data-Current-Year-To-Date-/5uac-w243)  
+**Terms of use**: https://www1.nyc.gov/home/terms-of-use.page
+
+## Prerequisites
+- Download the dataset by visiting the [NYPD Complaint Data Current (Year To Date)](https://data.cityofnewyork.us/Public-Safety/NYPD-Complaint-Data-Current-Year-To-Date-/5uac-w243) page, clicking the Export button, and choosing **TSV for Excel**.
+- Install [ClickHouse server and client](../../getting-started/install.md).
+- [Launch](../../getting-started/install.md#launch) ClickHouse server, and connect with `clickhouse-client`
+
+### A note about the commands described in this guide
+There are two types of commands in this guide:
+- Some of the commands are querying the TSV files, these are run at the command prompt.
+- The rest of the commands are querying ClickHouse, and these are run in the `clickhouse-client` or Play UI.
+
+:::note
+The examples in this guide assume that you have saved the TSV file to `${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv`, please adjust the commands if needed.
+:::
+
+## Familiarize yourself with the TSV file
+
+Before starting to work with the ClickHouse database familiarize yourself with the data. 
+
+### Look at the fields in the source TSV file
+
+This is an example of a command to query a TSV file, but don't run it yet.
+```sh
+clickhouse-local --query \
+"describe file('${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv', 'TSVWithNames')"
+```
+
+Sample response
+```response
+CMPLNT_NUM                  Nullable(Float64)					
+ADDR_PCT_CD                 Nullable(Float64)					
+BORO_NM                     Nullable(String)					
+CMPLNT_FR_DT                Nullable(String)					
+CMPLNT_FR_TM                Nullable(String)					
+```
+
+:::tip
+Most of the time the above command will let you know which fields in the input data are numeric, and which are strings, and which are tuples.  This is not always the case.  Because ClickHouse is routineley used with datasets containing billions of records there is a default number (100) of rows examined to [infer the schema](../../guides/developer/working-with-json/json-semi-structured.md/#relying-on-schema-inference) in order to avoid parsing billions of rows to infer the schema. The response below may not match what you see, as the dataset is updated several times each year. Looking at the Data Dictionary you can see that CMPLNT_NUM is specified as text, and not numeric.  By overriding the default of 100 rows for inference with the setting `SETTINGS input_format_max_rows_to_read_for_schema_inference=2000`
+you can get a better idea of the content.
+
+Note: as of version 22.5 the default is now 25,000 rows for inferring the schema, so only change the setting if you are on an older version or if you need more than 25,000 rows to be sampled.
+:::
+
+Run this command at your command prompt.  You will be using `clickhouse-local` to query the data in the TSV file you downloaded.
+```sh
+clickhouse-local --input_format_max_rows_to_read_for_schema_inference=2000 \
+--query \
+"describe file('${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv', 'TSVWithNames')" 
+```
+
+Result:
+```response
+CMPLNT_NUM        Nullable(String)					
+ADDR_PCT_CD       Nullable(Float64)					
+BORO_NM           Nullable(String)

+Longitude         Nullable(Float64)					
+Lat_Lon           Tuple(Nullable(Float64), Nullable(Float64))					
+New Georeferenced Column Nullable(String)
+```
+
+At this point you should check that the columns in the TSV file match the names and types specified in the **Columns in this Dataset** section of the [dataset web page](https://data.cityofnewyork.us/Public-Safety/NYPD-Complaint-Data-Current-Year-To-Date-/5uac-w243).  The data types are not very specific, all numeric fields are set to `Nullable(Float64)`, and all other fields are `Nullable(String)`.  When you create a ClickHouse table to store the data you can specify more appropriate and performant types.
+
+### Determine the proper schema
+
+In order to figure out what types should be used for the fields it is necessary to know what the data looks like. For example, the field `JURISDICTION_CODE` is a numeric: should it be a `UInt8`, or an `Enum`, or is `Float64` appropriate?
+
+```sql
+clickhouse-local --input_format_max_rows_to_read_for_schema_inference=2000 \
+--query \
+"select JURISDICTION_CODE, count() FROM
+ file('${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv', 'TSVWithNames')
+ GROUP BY JURISDICTION_CODE
+ ORDER BY JURISDICTION_CODE
+ FORMAT PrettyCompact"
+```
+
+Result:
+```response
+┌─JURISDICTION_CODE─┬─count()─┐
+│                 0 │  188875 │
+│                 1 │    4799 │

+│                97 │     405 │
+└───────────────────┴─────────┘
+```
+
+The query response shows that the `JURISDICTION_CODE` fits well in a `UInt8`.
+
+Similarly, look at some of the `String` fields and see if they are well suited to being `DateTime` or [`LowCardinality(String)`](../../sql-reference/data-types/lowcardinality.md) fields.
+
+For example, the field `PARKS_NM` is described as "Name of NYC park, playground or greenspace of occurrence, if applicable (state parks are not included)".  The names of parks in New York City may be a good candidate for a `LowCardinality(String)`:
+
+```sh
+clickhouse-local --input_format_max_rows_to_read_for_schema_inference=2000 \
+--query \
+"select count(distinct PARKS_NM) FROM
+ file('${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv', 'TSVWithNames')
+ FORMAT PrettyCompact"
+```
+
+Result:
+```response

+The dataset in use at the time of writing has only a few hundred distinct parks and playgrounds in the `PARK_NM` column.  This is a small number based on the [LowCardinality](../../sql-reference/data-types/lowcardinality.md#lowcardinality-dscr) recommendation to stay below 10,000 distinct strings in a `LowCardinality(String)` field.
+
+### DateTime fields
+Based on the **Columns in this Dataset** section of the [dataset web page](https://data.cityofnewyork.us/Public-Safety/NYPD-Complaint-Data-Current-Year-To-Date-/5uac-w243) there are date and time fields for the start and end of the reported event.  Looking at the min and max of the `CMPLNT_FR_DT` and `CMPLT_TO_DT` gives an idea of whether or not the fields are always populated:
+
+```sh title="CMPLNT_FR_DT"

+## Make a plan
+
+Based on the above investigation:
+- `JURISDICTION_CODE` should be cast as `UInt8`.
+- `PARKS_NM` should be cast to `LowCardinality(String)`
+- `CMPLNT_FR_DT` and `CMPLNT_FR_TM` are always populated (possibly with a default time of `00:00:00`)
+- `CMPLNT_TO_DT` and `CMPLNT_TO_TM` may be empty
+- Dates and times are stored in separate fields in the source
+- Dates are `mm/dd/yyyy` format
+- Times are `hh:mm:ss` format
+- Dates and times can be concatenated into DateTime types
+- There are some dates before January 1st 1970, which means we need a 64 bit DateTime
+
+:::note
+There are many more changes to be made to the types, they all can be determined by following the same investigation steps.  Look at the number of distinct strings in a field, the min and max of the numerics, and make your decisions.  The table schema that is given later in the guide has many low cardinality strings and unsigned integer fields and very few floating point numerics.
+:::
+
+## Concatenate the date and time fields
+
+To concatenate the date and time fields `CMPLNT_FR_DT` and `CMPLNT_FR_TM` into a single `String` that can be cast to a `DateTime`, select the two fields joined by the concatenation operator: `CMPLNT_FR_DT || ' ' || CMPLNT_FR_TM`.  The `CMPLNT_TO_DT` and `CMPLNT_TO_TM` fields are handled similarly.
+
+```sh
+clickhouse-local --input_format_max_rows_to_read_for_schema_inference=2000 \
+--query \
+"select CMPLNT_FR_DT || ' ' || CMPLNT_FR_TM AS complaint_begin FROM

+
+## Convert the date and time String to a DateTime64 type
+
+Earlier in the guide we discovered that there are dates in the TSV file before January 1st 1970, which means that we need a 64 bit DateTime type for the dates.  The dates also need to be converted from `MM/DD/YYYY` to `YYYY/MM/DD` format.  Both of these can be done with [`parseDateTime64BestEffort()`](../../sql-reference/functions/type-conversion-functions.md#parsedatetime64besteffort).
+
+```sh
+clickhouse-local --input_format_max_rows_to_read_for_schema_inference=2000 \
+--query \
+"WITH (CMPLNT_FR_DT || ' ' || CMPLNT_FR_TM) AS CMPLNT_START,
+      (CMPLNT_TO_DT || ' ' || CMPLNT_TO_TM) AS CMPLNT_END
+select parseDateTime64BestEffort(CMPLNT_START) AS complaint_begin,
+       parseDateTime64BestEffortOrNull(CMPLNT_END) AS complaint_end
+FROM file('${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv', 'TSVWithNames')
+ORDER BY complaint_begin ASC
+LIMIT 25
+FORMAT PrettyCompact"
+```
+
+Lines 2 and 3 above contain the concatenation from the previous step, and lines 4 and 5 above parse the strings into `DateTime64`.  As the complaint end time is not guaranteed to exist `parseDateTime64BestEffortOrNull` is used.

+The dates shown as `1925` above are from errors in the data.  There are several records in the original data with dates in the years `1019` - `1022` that should be `2019` - `2022`.  They are being stored as Jan 1st 1925 as that is the earliest date with a 64 bit DateTime.

+
+## Create a table
+
+The decisions made above on the data types used for the columns are reflected in the table schema
+below. We also need to decide on the `ORDER BY` and `PRIMARY KEY` used for the table.  At least one
+of `ORDER BY` or `PRIMARY KEY` must be specified.  Here are some guidelines on deciding on the 
+columns to includes in `ORDER BY`, and more information is in the *Next Steps* section at the end
+of this document.
+
+### Order By and Primary Key clauses
+
+- The `ORDER BY` tuple should include fields that are used in query filters
+- To maximize compression on disk the `ORDER BY` tuple should be ordered by ascending cardinality
+- If it exists, the `PRIMARY KEY` tuple must be a subset of the `ORDER BY` tuple
+- If only `ORDER BY` is specified, then the same tuple will be used as `PRIMARY KEY`
+- The primary key index is created using the `PRIMARY KEY` tuple if specified, otherwise the `ORDER BY` tuple
+- The `PRIMARY KEY` index is kept in main memory
+
+Looking at the dataset and the questions that might be answered by querying it we might
+decide that we would look at the types of crimes reported over time in the five boroughs of
+New York City.  These fields might be then included in the `ORDER BY`:
+
+| Column      | Description (from the data dictionary)                 |
+| ----------- | ---------------------------------------------------    |
+| OFNS_DESC   | Description of offense corresponding with key code     |
+| RPT_DT      | Date event was reported to police                      |
+| BORO_NM     | The name of the borough in which the incident occurred |
+
+
+Querying the TSV file for the cardinality of the three candidate columns:
+
+```bash
+clickhouse-local --input_format_max_rows_to_read_for_schema_inference=2000 \
+--query \
+"select formatReadableQuantity(uniq(OFNS_DESC)) as cardinality_OFNS_DESC,
+        formatReadableQuantity(uniq(RPT_DT)) as cardinality_RPT_DT,
+        formatReadableQuantity(uniq(BORO_NM)) as cardinality_BORO_NM
+  FROM
+  file('${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv', 'TSVWithNames')
+  FORMAT PrettyCompact"
+```
+
+Result:
+```response
+┌─cardinality_OFNS_DESC─┬─cardinality_RPT_DT─┬─cardinality_BORO_NM─┐
+│ 60.00                 │ 306.00             │ 6.00                │
+└───────────────────────┴────────────────────┴─────────────────────┘
+```
+Ordering by cardinality, the `ORDER BY` becomes:
+
+```
+ORDER BY ( BORO_NM, OFNS_DESC, RPT_DT )
+```
+:::note
+The table below will use more easily read column names, the above names will be mapped to
+```
+ORDER BY ( borough, offense_description, date_reported )
+```
+:::
+
+Putting together the changes to data types and the `ORDER BY` tuple gives this table structure:
+
+```sql
+CREATE TABLE NYPD_Complaint ( 
+    complaint_number     String,
+    precinct             UInt8,

+## Preprocess and Import Data {#preprocess-import-data}
+
+We will use `clickhouse-local` tool for data preprocessing and `clickhouse-client` to upload it.
+
+### `clickhouse-local` arguments used
+
+:::tip
+`table='input'` appears in the arguments to clickhouse-local below.  clickhouse-local takes the provided input (`cat ${HOME}/NYPD_Complaint_Data_Current__Year_To_Date_.tsv`) and inserts the input into a table.  By default the table is named `table`.  In this guide the name of the table is set to `input` to make the data flow clearer. The final argument to clickhouse-local is a query that selects from the table (`FROM input`) which is then piped to `clickhouse-client` to populate the table `NYPD_Complaint`.

-# Data backup and restore
-
 While [replication](../engines/table-engines/mergetree-family/replication.md) provides protection from hardware failures, it does not protect against human errors: accidental deletion of data, deletion of the wrong table or a table on the wrong cluster, and software bugs that result in incorrect data processing or data corruption. In many cases mistakes like these will affect all replicas. ClickHouse has built-in safeguards to prevent some types of mistakes — for example, by default [you can’t just drop tables with a MergeTree-like engine containing more than 50 Gb of data](server-configuration-parameters/settings.md#max-table-size-to-drop). However, these safeguards do not cover all possible cases and can be circumvented.
 
 In order to effectively mitigate possible human errors, you should carefully prepare a strategy for backing up and restoring your data **in advance**.

+## Using local cache {#using-local-cache}
+
+It is possible to configure local cache over disks in storage configuration starting from version 22.3. For versions 22.3 - 22.7 cache is supported only for `s3` disk type. For versions >= 22.8 cache is supported for any disk type: S3, Azure, Local, Encrypted, etc. Cache uses `LRU` cache policy.
+
+Example of configuration for versions later or equal to 22.8:
+
+``` xml
+<clickhouse>
+    <storage_configuration>
+        <disks>
+            <s3>

+
+Example of configuration for versions earlier than 22.8:

+
+Cache **configuration settings**:
+
+- `path` - path to the directory with cache. Default: None, this setting is obligatory.
+
+- `max_size` - maximum size of the cache in bytes. When the limit is reached, cache files are evicted according to the cache eviction policy. Default: None, this setting is obligatory.
+
+- `cache_on_write_operations` - allow to turn on `write-through` cache (caching data on any write operations: `INSERT` queries, background merges). Default: `false`. The `write-through` cache can be disabled per query using setting `enable_filesystem_cache_on_write_operations` (data is cached only if both cache config settings and corresponding query setting are enabled).
+
+- `enable_filesystem_query_cache_limit` - allow to limit the size of cache which is downloaded within each query (depends on user setting `max_query_cache_size`). Default: `false`.
+
+- `enable_cache_hits_threshold` - a number, which defines how many times some data needs to be read before it will be cached. Default: `0`, e.g. the data is cached at the first attempt to read it.
+
+- `do_not_evict_index_and_mark_files` - do not evict small frequently used files according to cache policy. Default: `true`.
+
+- `max_file_segment_size` - a maximum size of a single cache file. Default: `104857600` (100 Mb).
+
+- `max_elements` - a limit for a number of cache files. Default: `1048576`.
+
+Cache **query settings**:
+
+- `enable_filesystem_cache` - allows to disable cache per query even if storage policy was configured with `cache` disk type. Default: `true`.
+
+- `read_from_filesystem_cache_if_exists_otherwise_bypass_cache` - allows to use cache in query only if it already exists, otherwise query data will not be written to local cache storage. Default: `false`.
+
+- `enable_filesystem_cache_on_write_operations` - turn on `write-through` cache. This setting works only if setting `cache_on_write_operations` in cache configuration is turned on.
+
+- `enable_filesystem_cache_log` - turn on logging to `system.filesystem_cache_log` table. Gives a detailed view of cache usage per query. Default: `false`.
+
+- `max_query_cache_size` - a limit for the cache size, which can be written to local cache storage. Requires enabled `enable_filesystem_query_cache_limit` in cache configuration. Default: `false`.
+
+- `skip_download_if_exceeds_query_cache` - allows to change the behaviour of setting `max_query_cache_size`. Default: `true`. If this setting is turned on and cache download limit during query was reached, no more cache will be downloaded to cache storage. If this setting is turned off and cache download limit during query was reached, cache will still be written by cost of evicting previously downloaded (within current query) data, e.g. second behaviour allows to preserve `last recentltly used` behaviour while keeping query cache limit.
+
+** Warning **
+Cache configuration settings and cache query settings correspond to the latest ClickHouse version, for earlier versions something might not be supported.

+Cache **system tables**:
+
+- `system.filesystem_cache` - system tables which shows current state of cache.

 ## Storing Data on Web Server {#storing-data-on-webserver}
 
 There is a tool `clickhouse-static-files-uploader`, which prepares a data directory for a given table (`SELECT data_paths FROM system.tables WHERE name = 'table_name'`). For each table you need, you get a directory of files. These files can be uploaded to, for example, a web server with static files. After this preparation, you can load this table into any ClickHouse server via `DiskWeb`.

+The `ALTER TABLE` prefix makes this syntax different from most other systems supporting SQL. It is intended to signify that unlike similar queries in OLTP databases this is a heavy operation not designed for frequent use.  `ALTER TABLE` is considered a heavyweight operation that requires the underlying data to be merged before it is deleted.

+``` sql
+DELETE FROM [db.]table [WHERE expr]
+```
+
+`DELETE FROM` removes rows from table `[db.]table` that match expression `expr`. The deleted rows are marked as deleted immediately and will be automatically filtered out of all subsequent queries. Cleanup of data happens asynchronously in background. This feature is only available for MergeTree table engine family.
+
+For example, the following query deletes all rows from the `hits` table where the `Title` column contains the text `hello`:
+
+```sql
+DELETE FROM hits WHERE Title LIKE '%hello%';
+```
+
+Lightweight deletes are asynchronous by default. Set `mutations_sync` equal to 1 to wait for one replica to process the statement, and set `mutations_sync` to 2 to wait for all replicas.
+
+:::note
+This feature is experimental and requires you to set `allow_experimental_lightweight_delete` to true:
+
+```sql
+SET allow_experimental_lightweight_delete = true;
+```
+
+:::
+
+An [alternative way to delete rows](./alter/delete.md) in ClickHouse is `ALTER TABLE ... DELETE`, which might be more efficient if you do bulk deletes only occasionally and don't need the operation to be applied instantly. In most use cases the new lightweight `DELETE FROM` behavior will be considerably faster.
+
+:::warning
+Even though deletes are becoming more lightweight in ClickHouse, they should still not be used as aggressively as on an OLTP system. Ligthweight deletes are currently efficient for wide parts, but for compact parts they can be a heavyweight operation, and it may be better to use `ALTER TABLE` for some scenarios.
+:::

+Functional tests are the most simple and convenient to use. Most of ClickHouse features can be tested with functional tests and they are mandatory to use for every change in ClickHouse code that can be tested that way.
 
-每个功能测试都会向正在运行的 ClickHouse 服务器发送一个或多个查询, 并将结果与参考进行比较.
+Each functional test sends one or multiple queries to the running ClickHouse server and compares the result with reference.
 
-测试位于 `查询` 目录中. 有两个子目录: `无状态` 和 `有状态`. 无状态测试在没有任何预加载测试数据的情况下运行查询 - 它们通常在测试本身内即时创建小型合成数据集. 状态测试需要来自 Yandex.Metrica 的预加载测试数据, 它对公众开放.
+Tests are located in `queries` directory. There are two subdirectories: `stateless` and `stateful`. Stateless tests run queries without any preloaded test data - they often create small synthetic datasets on the fly, within the test itself. Stateful tests require preloaded test data from ClickHouse and it is available to general public.
 
-每个测试可以是两种类型之一: `.sql` 和 `.sh`. `.sql` 测试是简单的 SQL 脚本, 它通过管道传输到  `clickhouse-client --multiquery --testmode`. `.sh` 测试是一个自己运行的脚本. SQL 测试通常比 `.sh` 测试更可取. 仅当您必须测试某些无法从纯 SQL 中执行的功能时才应使用 `.sh` 测试, 例如将一些输入数据传送到 `clickhouse-client` 或测试 `clickhouse-local`.
+Each test can be one of two types: `.sql` and `.sh`. `.sql` test is the simple SQL script that is piped to `clickhouse-client --multiquery`. `.sh` test is a script that is run by itself. SQL tests are generally preferable to `.sh` tests. You should use `.sh` tests only when you have to test some feature that cannot be exercised from pure SQL, such as piping some input data into `clickhouse-client` or testing `clickhouse-local`.

+run, for example, the test `01428_hash_set_nan_key`, change to the repository
+folder and run the following command:
 
 ```
 PATH=$PATH:<path to clickhouse-client> tests/clickhouse-test 01428_hash_set_nan_key
 ```
 
-有关更多选项, 请参阅`tests/clickhouse-test --help`. 您可以简单地运行所有测试或运行由测试名称中的子字符串过滤的测试子集：`./clickhouse-test substring`. 还有并行或随机顺序运行测试的选项.
+For more options, see `tests/clickhouse-test --help`. You can simply run all tests or run subset of tests filtered by substring in test name: `./clickhouse-test substring`. There are also options to run tests in parallel or in randomized order.
 
-### 添加新测试 {#adding-new-test}
+### Adding a New Test
 
-添加新的测试, 在 `queries/0_stateless` 目录下创建 `.sql` 或 `.sh` 文件, 手动检查, 然后通过以下方式生成`.reference`文件：`clickhouse-client -n --testmode < 00000_test.sql > 00000_test.reference` 或 `./00000_test.sh > ./00000_test.reference`.
+To add new test, create a `.sql` or `.sh` file in `queries/0_stateless` directory, check it manually and then generate `.reference` file in the following way: `clickhouse-client --multiquery < 00000_test.sql > 00000_test.reference` or `./00000_test.sh > ./00000_test.reference`.
 
-测试应仅使用(创建、删除等)`test` 数据库中假定已预先创建的表; 测试也可以使用临时表.
+Tests should use (create, drop, etc) only tables in `test` database that is assumed to be created beforehand; also tests can use temporary tables.
 
-### 选择测试名称 {#choosing-test-name}
+### Choosing the Test Name
 
-测试名称以五位数前缀开头, 后跟描述性名称, 例如 `00422_hash_function_constexpr.sql`. 要选择前缀, 请找到目录中已存在的最大前缀, 并将其加一. 在此期间, 可能会添加一些具有相同数字前缀的其他测试, 但这没关系并且不会导致任何问题, 您以后不必更改它.
+The name of the test starts with a five-digit prefix followed by a descriptive name, such as `00422_hash_function_constexpr.sql`. To choose the prefix, find the largest prefix already present in the directory, and increment it by one. In the meantime, some other tests might be added with the same numeric prefix, but this is OK and does not lead to any problems, you don't have to change it later.
 
-一些测试的名称中标有 `zookeeper`、`shard` 或 `long` . `zookeeper` 用于使用 ZooKeeper 的测试. `shard` 用于需要服务器监听 `127.0.0.*` 的测试; `distributed` 或 `global` 具有相同的含义. `long` 用于运行时间稍长于一秒的测试. Yo你可以分别使用 `--no-zookeeper`、`--no-shard` 和 `--no-long` 选项禁用这些测试组. 如果需要 ZooKeeper 或分布式查询，请确保为您的测试名称添加适当的前缀.
+Some tests are marked with `zookeeper`, `shard` or `long` in their names. `zookeeper` is for tests that are using ZooKeeper. `shard` is for tests that requires server to listen `127.0.0.*`; `distributed` or `global` have the same meaning. `long` is for tests that run slightly longer that one second. You can disable these groups of tests using `--no-zookeeper`, `--no-shard` and `--no-long` options, respectively. Make sure to add a proper prefix to your test name if it needs ZooKeeper or distributed queries.
 
-### 检查必须发生的错误 {#checking-error-must-occur}
+### Checking for an Error that Must Occur
 
-有时您想测试是否因不正确的查询而发生服务器错误. 我们支持在 SQL 测试中对此进行特殊注释, 形式如下:
+Sometimes you want to test that a server error occurs for an incorrect query. We support special annotations for this in SQL tests, in the following form:
 ```
 select x; -- { serverError 49 }
 ```
-此测试确保服务器返回关于未知列“x”的错误代码为 49. 如果没有错误, 或者错误不同, 则测试失败. 如果您想确保错误发生在客户端, 请改用 `clientError` 注释.
+This test ensures that the server returns an error with code 49 about unknown column `x`. If there is no error, or the error is different, the test will fail. If you want to ensure that an error occurs on the client side, use `clientError` annotation instead.
 
-不要检查错误消息的特定措辞, 它将来可能会发生变化, 并且测试将不必要地中断. 只检查错误代码. 如果现有的错误代码不足以满足您的需求, 请考虑添加一个新的.
+Do not check for a particular wording of error message, it may change in the future, and the test will needlessly break. Check only the error code. If the existing error code is not precise enough for your needs, consider adding a new one.
 
-### 测试分布式查询 {#testing-distributed-query}
+### Testing a Distributed Query
 
-如果你想在功能测试中使用分布式查询, 你可以使用 `127.0.0.{1..2}` 的地址, 以便服务器查询自己; 或者您可以在服务器配置文件中使用预定义的测试集群, 例如`test_shard_localhost`. 请记住在测试名称中添加 `shard` 或 `distributed` 字样, 以便它以正确的配置在 CI 中运行, 其中服务器配置为支持分布式查询.
+If you want to use distributed queries in functional tests, you can leverage `remote` table function with `127.0.0.{1..2}` addresses for the server to query itself; or you can use predefined test clusters in server configuration file like `test_shard_localhost`. Remember to add the words `shard` or `distributed` to the test name, so that it is run in CI in correct configurations, where the server is configured to support distributed queries.
 
 
-## 已知错误 {#known-bugs}
+## Known Bugs {#known-bugs}
 
-如果我们知道一些可以通过功能测试轻松重现的错误, 我们将准备好的功能测试放在 `tests/queries/bugs` 目录中. 修复错误后, 这些测试将移至 `tests/queries/0_stateless` .
+If we know some bugs that can be easily reproduced by functional tests, we place prepared functional tests in `tests/queries/bugs` directory. These tests will be moved to `tests/queries/0_stateless` when bugs are fixed.
 
-## 集成测试 {#integration-tests}
+## Integration Tests {#integration-tests}
 
-集成测试允许在集群配置中测试 ClickHouse 以及 ClickHouse 与其他服务器(如 MySQL、Postgres、MongoDB)的交互. 它们可以用来模拟网络分裂、丢包等情况. 这些测试在Docker下运行, 并使用各种软件创建多个容器.
+Integration tests allow testing ClickHouse in clustered configuration and ClickHouse interaction with other servers like MySQL, Postgres, MongoDB. They are useful to emulate network splits, packet drops, etc. These tests are run under Docker and create multiple containers with various software.
 
-有关如何运行这些测试, 请参阅 `tests/integration/README.md` .
+See `tests/integration/README.md` on how to run these tests.
 
-注意, ClickHouse与第三方驱动程序的集成没有经过测试. 另外, 我们目前还没有JDBC和ODBC驱动程序的集成测试.
+Note that integration of ClickHouse with third-party drivers is not tested. Also, we currently do not have integration tests with our JDBC and ODBC drivers.
 
-## 单元测试 {#unit-tests}
+## Unit Tests {#unit-tests}
 
-当您想测试的不是 ClickHouse 整体, 而是单个独立库或类时，单元测试很有用. 您可以使用 `ENABLE_TESTS` CMake 选项启用或禁用测试构建. 单元测试(和其他测试程序)位于代码中的 `tests` 子目录中. 要运行单元测试, 请键入 `ninja test` 。有些测试使用 `gtest` , 但有些程序在测试失败时会返回非零退出码.
+Unit tests are useful when you want to test not the ClickHouse as a whole, but a single isolated library or class. You can enable or disable build of tests with `ENABLE_TESTS` CMake option. Unit tests (and other test programs) are located in `tests` subdirectories across the code. To run unit tests, type `ninja test`. Some tests use `gtest`, but some are just programs that return non-zero exit code on test failure.
 
-如果代码已经被功能测试覆盖了, 就没有必要进行单元测试(而且功能测试通常更易于使用).
+It’s not necessary to have unit tests if the code is already covered by functional tests (and functional tests are usually much more simple to use).
 
-例如, 您可以通过直接调用可执行文件来运行单独的 gtest 检查:
+You can run individual gtest checks by calling the executable directly, for example:
 
 ```bash
 $ ./src/unit_tests_dbms --gtest_filter=LocalAddress*
 ```
 
-## 性能测试 {#performance-tests}
+## Performance Tests {#performance-tests}
 
-性能测试允许测量和比较 ClickHouse 的某些孤立部分在合成查询上的性能. 测试位于 `tests/performance`. 每个测试都由带有测试用例描述的 `.xml` 文件表示. 测试使用 `docker/tests/performance-comparison` 工具运行. 请参阅自述文件以进行调用.
+Performance tests allow to measure and compare performance of some isolated part of ClickHouse on synthetic queries. Performance tests are located at `tests/performance/`. Each test is represented by an `.xml` file with a description of the test case. Tests are run with `docker/test/performance-comparison` tool . See the readme file for invocation.
 
-每个测试在循环中运行一个或多个查询(可能带有参数组合). 一些测试可以包含预加载测试数据集的先决条件.
+Each test run one or multiple queries (possibly with combinations of parameters) in a loop.
 
-如果您希望在某些场景中提高ClickHouse的性能，并且如果可以在简单的查询中观察到改进，那么强烈建议编写性能测试。在测试期间使用 `perf top` 或其他perf工具总是有意义的.
+If you want to improve performance of ClickHouse in some scenario, and if improvements can be observed on simple queries, it is highly recommended to write a performance test. Also, it is recommended to write performance tests when you add or modify SQL functions which are relatively isolated and not too obscure. It always makes sense to use `perf top` or other `perf` tools during your tests.
 
-## 测试工具和脚本 {#test-tools-and-scripts}
+## Test Tools and Scripts {#test-tools-and-scripts}
 
-  `tests` 目录中的一些程序不是准备好的测试，而是测试工具. 例如, 对于 `Lexer`, 有一个工具 `src/Parsers/tests/lexer` , 它只是对标准输入进行标记化并将着色结果写入标准输出. 您可以将这些类型的工具用作代码示例以及用于探索和手动测试.
+Some programs in `tests` directory are not prepared tests, but are test tools. For example, for `Lexer` there is a tool `src/Parsers/tests/lexer` that just do tokenization of stdin and writes colorized result to stdout. You can use these kind of tools as a code examples and for exploration and manual testing.
 
-## 其他测试 {#miscellaneous-tests}
+## Miscellaneous Tests {#miscellaneous-tests}
 
-在 `tests/external_models` 中有机器学习模型的测试. 这些测试不会更新, 必须转移到集成测试.
+There are tests for machine learned models in `tests/external_models`. These tests are not updated and must be transferred to integration tests.
 
-仲裁插入有单独的测试. 该测试在不同的服务器上运行 ClickHouse 集群并模拟各种故障情况：网络分裂、丢包(ClickHouse 节点之间、ClickHouse 和 ZooKeeper 之间、ClickHouse 服务器和客户端之间等)、`kill -9`、`kill -STOP` 和 `kill -CONT` , 比如 [Jepsen](https://aphyr.com/tags/Jepsen). 然后测试检查所有已确认的插入是否已写入并且所有被拒绝的插入均未写入.
+There is separate test for quorum inserts. This test run ClickHouse cluster on separate servers and emulate various failure cases: network split, packet drop (between ClickHouse nodes, between ClickHouse and ZooKeeper, between ClickHouse server and client, etc.), `kill -9`, `kill -STOP` and `kill -CONT` , like [Jepsen](https://aphyr.com/tags/Jepsen). Then the test checks that all acknowledged inserts was written and all rejected inserts was not.
 
-在 ClickHouse 开源之前, Quorum 测试是由单独的团队编写的. 这个团队不再与ClickHouse合作. 测试碰巧是用Java编写的. 由于这些原因, 必须重写仲裁测试并将其转移到集成测试.
+Quorum test was written by separate team before ClickHouse was open-sourced. This team no longer work with ClickHouse. Test was accidentally written in Java. For these reasons, quorum test must be rewritten and moved to integration tests.
 
-## 手动测试 {#manual-testing}
+## Manual Testing {#manual-testing}
 
-当您开发一个新特性时, 手动测试它也是合理的. 您可以按照以下步骤进行操作:
+When you develop a new feature, it is reasonable to also test it manually. You can do it with the following steps:
 
-构建 ClickHouse. 从终端运行 ClickHouse：将目录更改为 `programs/clickhouse-server` 并使用 `./clickhouse-server` 运行它.  默认情况下, 它将使用当前目录中的配置(`config.xml`、`users.xml` 和`config.d` 和`users.d` 目录中的文件). 要连接到 ClickHouse 服务器, 请运行 `programs/clickhouse-client/clickhouse-client` .
+Build ClickHouse. Run ClickHouse from the terminal: change directory to `programs/clickhouse-server` and run it with `./clickhouse-server`. It will use configuration (`config.xml`, `users.xml` and files within `config.d` and `users.d` directories) from the current directory by default. To connect to ClickHouse server, run `programs/clickhouse-client/clickhouse-client`.
 
-请注意, 所有 clickhouse 工具(服务器、客户端等)都只是指向名为 `clickhouse` 的单个二进制文件的符号链接. 你可以在 `programs/clickhouse` 找到这个二进制文件. 所有工具也可以作为 `clickhouse tool` 而不是 `clickhouse-tool` 调用.
+Note that all clickhouse tools (server, client, etc) are just symlinks to a single binary named `clickhouse`. You can find this binary at `programs/clickhouse`. All tools can also be invoked as `clickhouse tool` instead of `clickhouse-tool`.
 
-或者, 您可以安装 ClickHouse 包: 从 Yandex 存储库稳定发布, 或者您可以在 ClickHouse 源根目录中使用 `./release` 为自己构建包. 然后使用 `sudo service clickhouse-server start` 启动服务器(或停止以停止服务器). 在 `/etc/clickhouse-server/clickhouse-server.log` 中查找日志.
+Alternatively you can install ClickHouse package: either stable release from ClickHouse repository or you can build package for yourself with `./release` in ClickHouse sources root. Then start the server with `sudo clickhouse start` (or stop to stop the server). Look for logs at `/etc/clickhouse-server/clickhouse-server.log`.
 
-当您的系统上已经安装了 ClickHouse 时，您可以构建一个新的 `clickhouse` 二进制文件并替换现有的二进制文件:
+When ClickHouse is already installed on your system, you can build a new `clickhouse` binary and replace the existing binary:
 
 ``` bash
-$ sudo service clickhouse-server stop
+$ sudo clickhouse stop
 $ sudo cp ./clickhouse /usr/bin/
-$ sudo service clickhouse-server start
+$ sudo clickhouse start
 ```
 
-您也可以停止系统 clickhouse-server 并使用相同的配置运行您自己的服务器, 但登录到终端:
+Also you can stop system clickhouse-server and run your own with the same configuration but with logging to terminal:
 
 ``` bash
-$ sudo service clickhouse-server stop
+$ sudo clickhouse stop
 $ sudo -u clickhouse /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml
 ```
 
-使用 gdb 的示例:
+Example with gdb:
 
 ``` bash
 $ sudo -u clickhouse gdb --args /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml
 ```
 
-如果系统 clickhouse-server 已经在运行并且你不想停止它, 你可以在你的 `config.xml` 中更改端口号(或在 `config.d` 目录中的文件中覆盖它们), 提供适当的数据路径, 并运行它.
+If the system clickhouse-server is already running and you do not want to stop it, you can change port numbers in your `config.xml` (or override them in a file in `config.d` directory), provide appropriate data path, and run it.
 
-`clickhouse` 二进制文件几乎没有依赖关系, 可以在广泛的 Linux 发行版中使用. 要在服务器上快速而肮脏地测试您的更改, 您可以简单地将新构建的 `clickhouse` 二进制文件 `scp` 到您的服务器, 然后按照上面的示例运行它.
+`clickhouse` binary has almost no dependencies and works across wide range of Linux distributions. To quick and dirty test your changes on a server, you can simply `scp` your fresh built `clickhouse` binary to your server and then run it as in examples above.
 
-## 测试环境 {#testing-environment}
+## Build Tests {#build-tests}
 
-在发布稳定版之前, 我们将其部署在测试环境中.测试环境是一个集群，处理 [Yandex.Metrica](https://metrica.yandex.com/) 数据的 1/39 部分. 我们与 Yandex.Metrica 团队共享我们的测试环境. ClickHouse无需在现有数据上停机即可升级. 我们首先看到的是, 数据被成功地处理了, 没有滞后于实时, 复制继续工作, Yandex.Metrica 团队没有发现任何问题. 第一次检查可以通过以下方式进行:
+Build tests allow to check that build is not broken on various alternative configurations and on some foreign systems. These tests are automated as well.
 
-``` sql
-SELECT hostName() AS h, any(version()), any(uptime()), max(UTCEventTime), count() FROM remote('example01-01-{1..3}t', merge, hits) WHERE EventDate >= today() - 2 GROUP BY h ORDER BY h;
-```
+Examples:
+-   cross-compile for Darwin x86_64 (Mac OS X)
+-   cross-compile for FreeBSD x86_64
+-   cross-compile for Linux AArch64
+-   build on Ubuntu with libraries from system packages (discouraged)
+-   build with shared linking of libraries (discouraged)
 
-在某些情况下, 我们还会部署到 Yandex 中我们朋友团队的测试环境：Market、Cloud 等. 此外, 我们还有一些用于开发目的的硬件服务器.
+For example, build with system packages is bad practice, because we cannot guarantee what exact version of packages a system will have. But this is really needed by Debian maintainers. For this reason we at least have to support this variant of build. Another example: shared linking is a common source of trouble, but it is needed for some enthusiasts.
 
-## 负载测试 {#load-testing}
+Though we cannot run all tests on all variant of builds, we want to check at least that various build variants are not broken. For this purpose we use build tests.
 
-部署到测试环境后, 我们使用来自生产集群的查询运行负载测试. 这是手动完成的.
+We also test that there are no translation units that are too long to compile or require too much RAM.
 
-确保您在生产集群上启用了 `query_log`.
+We also test that there are no too large stack frames.
 
-收集一天或更长时间的查询日志:
+## Testing for Protocol Compatibility {#testing-for-protocol-compatibility}
 
-``` bash
-$ clickhouse-client --query="SELECT DISTINCT query FROM system.query_log WHERE event_date = today() AND query LIKE '%ym:%' AND query NOT LIKE '%system.query_log%' AND type = 2 AND is_initial_query" > queries.tsv
-```
+When we extend ClickHouse network protocol, we test manually that old clickhouse-client works with new clickhouse-server and new clickhouse-client works with old clickhouse-server (simply by running binaries from corresponding packages).
 
-这是一个复杂的例子. `type = 2` 将过滤成功执行的查询. `query LIKE '%ym:%'` 是从 Yandex.Metrica 中选择相关查询. `is_initial_query` 是只选择客户端发起的查询, 而不是 ClickHouse 本身(作为分布式查询处理的一部分).
+We also test some cases automatically with integrational tests:
+- if data written by old version of ClickHouse can be successfully read by the new version;
+- do distributed queries work in a cluster with different ClickHouse versions.
 
-`scp` 将此日志记录到您的测试集群并按如下方式运行它:
+## Help from the Compiler {#help-from-the-compiler}
 
-``` bash
-$ clickhouse benchmark --concurrency 16 < queries.tsv
-```
+Main ClickHouse code (that is located in `dbms` directory) is built with `-Wall -Wextra -Werror` and with some additional enabled warnings. Although these options are not enabled for third-party libraries.
 
-(可能你还想指定一个 `--user`)
+Clang has even more useful warnings - you can look for them with `-Weverything` and pick something to default build.
 
-然后把它留到晚上或周末, 去休息一下.
+For production builds, clang is used, but we also test make gcc builds. For development, clang is usually more convenient to use. You can build on your own machine with debug mode (to save battery of your laptop), but please note that compiler is able to generate more warnings with `-O3` due to better control flow and inter-procedure analysis. When building with clang in debug mode, debug version of `libc++` is used that allows to catch more errors at runtime.
 
-您应该检查 `clickhouse-server` 没有崩溃, 内存占用是有限的, 且性能不会随着时间的推移而降低.
+## Sanitizers {#sanitizers}
 
-由于查询和环境的高度可变性, 没有记录和比较精确的查询执行时间.
+### Address sanitizer
+We run functional, integration, stress and unit tests under ASan on per-commit basis.
 
-## 构建测试 {#build-tests}
+### Thread sanitizer
+We run functional, integration, stress and unit tests under TSan on per-commit basis.
 
-构建测试允许检查在各种可选配置和一些外部系统上的构建是否被破坏. 这些测试也是自动化的.
+### Memory sanitizer
+We run functional, integration, stress and unit tests under MSan on per-commit basis.
 
-示例:
--   Darwin x86_64 (Mac OS X) 交叉编译
--   FreeBSD x86_64 交叉编译
--   Linux AArch64 交叉编译
--   使用系统包中的库在 Ubuntu 上构建（不鼓励）
--   使用库的共享链接构建（不鼓励）
-
-例如, 使用系统包构建是不好的做法, 因为我们无法保证系统将拥有哪个确切版本的包. 但这确实是 Debian 维护者所需要的. 出于这个原因, 我们至少必须支持这种构建变体. 另一个例子: 共享链接是一个常见的麻烦来源, 但对于一些爱好者来说是需要的.
-
-虽然我们无法对所有构建变体运行所有测试, 但我们希望至少检查各种构建变体没有被破坏. 为此, 我们使用构建测试.
-
-我们还测试了那些太长而无法编译或需要太多RAM的没有翻译单元.
-
-我们还测试没有太大的堆栈帧.
-
-## 协议兼容性测试 {#testing-for-protocol-compatibility}
-
-当我们扩展 ClickHouse 网络协议时, 我们手动测试旧的 clickhouse-client 与新的 clickhouse-server 一起工作, 而新的 clickhouse-client 与旧的 clickhouse-server 一起工作(只需从相应的包中运行二进制文件).
-
-我们还使用集成测试自动测试一些案例:
-- 旧版本ClickHouse写入的数据是否可以被新版本成功读取;
-- 在具有不同 ClickHouse 版本的集群中执行分布式查询.
-
-## 编译器的帮助 {#help-from-the-compiler}
-
-主要的 ClickHouse 代码(位于 `dbms` 目录中)是用 `-Wall -Wextra -Werror` 和一些额外的启用警告构建的. 虽然没有为第三方库启用这些选项.
-
-Clang 有更多有用的警告 - 你可以用 `-Weverything` 寻找它们并选择一些东西来默认构建.
-
-对于生产构建, 使用 clang, 但我们也测试 make gcc 构建. 对于开发, clang 通常使用起来更方便. 您可以使用调试模式在自己的机器上构建(以节省笔记本电脑的电池), 但请注意, 由于更好的控制流和过程间分析, 编译器能够使用 `-O3` 生成更多警告. 在调试模式下使用 clang 构建时, 使用调试版本的 `libc++` 允许在运行时捕获更多错误.
-
-## 地址清理器 {#sanitizers}
-
-### 地址清理器
-我们在ASan上运行功能测试、集成测试、压力测试和单元测试.
-
-### 线程清理器
-我们在TSan下运行功能测试、集成测试、压力测试和单元测试.
-
-### 内存清理器
-我们在MSan上运行功能测试、集成测试、压力测试和单元测试.
-
-### 未定义的行为清理器
-我们在UBSan下运行功能测试、集成测试、压力测试和单元测试. 某些第三方库的代码未针对 UB 进行清理.
+### Undefined behaviour sanitizer
+We run functional, integration, stress and unit tests under UBSan on per-commit basis. The code of some third-party libraries is not sanitized for UB.
 
 ### Valgrind (Memcheck)
-我们曾经在 Valgrind 下通宵运行功能测试, 但不再这样做了. 这需要几个小时. 目前在`re2`库中有一个已知的误报, 见[这篇文章](https://research.swtch.com/sparse).
+We used to run functional tests under Valgrind overnight, but don't do it anymore. It takes multiple hours. Currently there is one known false positive in `re2` library, see [this article](https://research.swtch.com/sparse).
 
-## 模糊测试 {#fuzzing}
+## Fuzzing {#fuzzing}
 
-ClickHouse 模糊测试是使用 [libFuzzer](https://llvm.org/docs/LibFuzzer.html) 和随机 SQL 查询实现的. 所有模糊测试都应使用sanitizers(地址和未定义)进行.
+ClickHouse fuzzing is implemented both using [libFuzzer](https://llvm.org/docs/LibFuzzer.html) and random SQL queries.
+All the fuzz testing should be performed with sanitizers (Address and Undefined).
 
-LibFuzzer 用于库代码的隔离模糊测试. Fuzzer 作为测试代码的一部分实现, 并具有 `_fuzzer` 名称后缀.
-Fuzzer 示例可以在 `src/Parsers/tests/lexer_fuzzer.cpp` 中找到. LibFuzzer 特定的配置、字典和语料库存储在 `tests/fuzz` 中.
-我们鼓励您为处理用户输入的每个功能编写模糊测试.
+LibFuzzer is used for isolated fuzz testing of library code. Fuzzers are implemented as part of test code and have “_fuzzer” name postfixes.
+Fuzzer example can be found at `src/Parsers/fuzzers/lexer_fuzzer.cpp`. LibFuzzer-specific configs, dictionaries and corpus are stored at `tests/fuzz`.
+We encourage you to write fuzz tests for every functionality that handles user input.
 
-默认情况下不构建模糊器. 要构建模糊器, 应设置` -DENABLE_FUZZING=1` 和 `-DENABLE_TESTS=1` 选项.
-我们建议在构建模糊器时禁用 Jemalloc. 用于将 ClickHouse fuzzing 集成到 Google OSS-Fuzz 的配置可以在 `docker/fuzz` 中找到.
+Fuzzers are not built by default. To build fuzzers both `-DENABLE_FUZZING=1` and `-DENABLE_TESTS=1` options should be set.
+We recommend to disable Jemalloc while building fuzzers. Configuration used to integrate ClickHouse fuzzing to
+Google OSS-Fuzz can be found at `docker/fuzz`.
 
-我们还使用简单的模糊测试来生成随机SQL查询, 并检查服务器在执行这些查询时是否会死亡.
-你可以在 `00746_sql_fuzzy.pl` 中找到它. 这个测试应该连续运行(通宵或更长时间).
+We also use simple fuzz test to generate random SQL queries and to check that the server does not die executing them.
+You can find it in `00746_sql_fuzzy.pl`. This test should be run continuously (overnight and longer).
 
-我们还使用复杂的基于 AST 的查询模糊器, 它能够找到大量的极端情况. 它在查询 AST 中进行随机排列和替换. 它会记住先前测试中的 AST 节点, 以使用它们对后续测试进行模糊测试, 同时以随机顺序处理它们. 您可以在 [这篇博客文章](https://clickhouse.com/blog/en/2021/fuzzing-clickhouse/) 中了解有关此模糊器的更多信息.
+We also use sophisticated AST-based query fuzzer that is able to find huge amount of corner cases. It does random permutations and substitutions in queries AST. It remembers AST nodes from previous tests to use them for fuzzing of subsequent tests while processing them in random order. You can learn more about this fuzzer in [this blog article](https://clickhouse.com/blog/en/2021/fuzzing-clickhouse/).
 
-## 压力测试 {#stress-test}
+## Stress test
 
-压力测试是另一种模糊测试. 它使用单个服务器以随机顺序并行运行所有功能测试. 不检查测试结果.
+Stress tests are another case of fuzzing. It runs all functional tests in parallel in random order with a single server. Results of the tests are not checked.
 
-经检查:
-- 服务器不会崩溃，不会触发调试或清理程序陷阱;
-- 没有死锁;
-- 数据库结构一致;
-- 服务器可以在测试后成功停止并重新启动，没有异常;
+It is checked that:
+- server does not crash, no debug or sanitizer traps are triggered;
+- there are no deadlocks;
+- the database structure is consistent;
+- server can successfully stop after the test and start again without exceptions.
 
-有五种变体 (Debug, ASan, TSan, MSan, UBSan).
+There are five variants (Debug, ASan, TSan, MSan, UBSan).
 
-## 线程模糊器 {#thread-fuzzer}
+## Thread Fuzzer
 
-Thread Fuzzer(请不要与 Thread Sanitizer 混淆)是另一种允许随机化线程执行顺序的模糊测试. 它有助于找到更多特殊情况.
+Thread Fuzzer (please don't mix up with Thread Sanitizer) is another kind of fuzzing that allows to randomize thread order of execution. It helps to find even more special cases.
 
-## 安全审计 {#security-audit}
+## Security Audit
 
-Yandex安全团队的人员从安全的角度对ClickHouse的功能做了一些基本的概述.
+Our Security Team did some basic overview of ClickHouse capabilities from the security standpoint.
 
-## 静态分析仪 {#static-analyzers}
+## Static Analyzers {#static-analyzers}
 
-我们在每次提交的基础上运行 `clang-tidy`. `clang-static-analyzer` 检查也被启用. `clang-tidy` 也用于一些样式检查.
+We run `clang-tidy` on per-commit basis. `clang-static-analyzer` checks are also enabled. `clang-tidy` is also used for some style checks.
 
-我们已经评估了 `clang-tidy`、`Coverity`、`cppcheck`、`PVS-Studio`、`tscancode`、`CodeQL`. 您将在 `tests/instructions/` 目录中找到使用说明. 你也可以阅读[俄文文章](https://habr.com/company/yandex/blog/342018/).
+We have evaluated `clang-tidy`, `Coverity`, `cppcheck`, `PVS-Studio`, `tscancode`, `CodeQL`. You will find instructions for usage in `tests/instructions/` directory.

+If you use `CLion` as an IDE, you can leverage some `clang-tidy` checks out of the box.
 
-我们还使用 `shellcheck` 对shell脚本进行静态分析.
+We also use `shellcheck` for static analysis of shell scripts.

-在调试版本中, 我们使用自定义分配器执行用户级分配的 ASLR.
+In debug build we are using custom allocator that does ASLR of user-level allocations.
 
-我们还手动保护在分配后预期为只读的内存区域.
+We also manually protect memory regions that are expected to be readonly after allocation.
 
-在调试构建中, 我们还需要对libc进行自定义, 以确保不会调用 "有害的" (过时的、不安全的、非线程安全的)函数.
+In debug build we also involve a customization of libc that ensures that no "harmful" (obsolete, insecure, not thread-safe) functions are called.
 
-Debug 断言被广泛使用.
+Debug assertions are used extensively.
 
-在调试版本中，如果抛出带有 "逻辑错误" 代码(暗示错误)的异常, 则程序会过早终止. 它允许在发布版本中使用异常, 但在调试版本中使其成为断言.
+In debug build, if exception with "logical error" code (implies a bug) is being thrown, the program is terminated prematurely. It allows to use exceptions in release build but make it an assertion in debug build.
 
-jemalloc 的调试版本用于调试版本.
-libc++ 的调试版本用于调试版本.
+Debug version of jemalloc is used for debug builds.
+Debug version of libc++ is used for debug builds.
 
-## 运行时完整性检查
+## Runtime Integrity Checks
 
-对存储在磁盘上的数据是校验和. MergeTree 表中的数据同时以三种方式进行校验和*(压缩数据块、未压缩数据块、跨块的总校验和). 客户端和服务器之间或服务器之间通过网络传输的数据也会进行校验和. 复制确保副本上的数据位相同.
+Data stored on disk is checksummed. Data in MergeTree tables is checksummed in three ways simultaneously* (compressed data blocks, uncompressed data blocks, the total checksum across blocks). Data transferred over network between client and server or between servers is also checksummed. Replication ensures bit-identical data on replicas.
 
-需要防止硬件故障(存储介质上的位腐烂、服务器上 RAM 中的位翻转、网络控制器 RAM 中的位翻转、网络交换机 RAM 中的位翻转、客户端 RAM 中的位翻转、线路上的位翻转). 请注意，比特位操作很常见, 即使对于 ECC RAM 和 TCP 校验和(如果您每天设法运行数千台处理 PB 数据的服务器, 也可能发生比特位操作. [观看视频(俄语)](https://www.youtube.com/watch?v=ooBAQIe0KlQ).
+It is required to protect from faulty hardware (bit rot on storage media, bit flips in RAM on server, bit flips in RAM of network controller, bit flips in RAM of network switch, bit flips in RAM of client, bit flips on the wire). Note that bit flips are common and likely to occur even for ECC RAM and in presence of TCP checksums (if you manage to run thousands of servers processing petabytes of data each day). [See the video (russian)](https://www.youtube.com/watch?v=ooBAQIe0KlQ).
 
-ClickHouse 提供诊断功能, 可帮助运维工程师找到故障硬件.
+ClickHouse provides diagnostics that will help ops engineers to find faulty hardware.
 
-\* 它并不慢.
+\* and it is not slow.
 
-## 代码风格 {#code-style}
+## Code Style {#code-style}
 
-[此处](style.md)描述了代码样式规则.
+Code style rules are described [here](style.md).
 
-要检查一些常见的样式违规，您可以使用 `utils/check-style` 脚本.
+To check for some common style violations, you can use `utils/check-style` script.
 
-要强制使用正确的代码样式, 您可以使用 `clang-format`. 文件 `.clang-format` 位于源根目录. 它大多与我们的实际代码风格相对应. 但是不建议将 `clang-format` 应用于现有文件, 因为它会使格式变得更糟. 您可以使用可以在 clang 源代码库中找到的 `clang-format-diff` 工具.
+To force proper style of your code, you can use `clang-format`. File `.clang-format` is located at the sources root. It mostly corresponding with our actual code style. But it’s not recommended to apply `clang-format` to existing files because it makes formatting worse. You can use `clang-format-diff` tool that you can find in clang source repository.
 
-或者, 您可以尝试使用 `uncrustify` 工具来重新格式化您的代码. 配置位于源根目录中的 `uncrustify.cfg` 中. 它比 `clang-format` 测试更少.
+Alternatively you can try `uncrustify` tool to reformat your code. Configuration is in `uncrustify.cfg` in the sources root. It is less tested than `clang-format`.
 
-`CLion` 有自己的代码格式化程序, 必须根据我们的代码风格进行调整.
+`CLion` has its own code formatter that has to be tuned for our code style.
 
-我们还使用 `codespell` 来查找代码中的拼写错误.它也是自动化的.
+We also use `codespell` to find typos in code. It is automated as well.
 
-## Metrica B2B 测试 {#metrica-b2b-tests}
+## Test Coverage {#test-coverage}
 
-每个 ClickHouse 版本都使用 Yandex Metrica 和 AppMetrica 引擎进行测试. ClickHouse 的测试版和稳定版部署在 VM 上, 并使用 Metrica 引擎的小副本运行, 该引擎处理输入数据的固定样本. 然后将两个 Metrica 引擎实例的结果放在一起比较.
-
-这些测试由单独的团队自动化. 由于移动部件数量众多, 测试在大多数情况下都因完全不相关的原因而失败, 这些原因很难弄清楚. 这些测试很可能对我们有负面价值. 尽管如此, 这些测试在数百次中被证明是有用的.
-
-## 测试覆盖率 {#test-coverage}
-
-我们还跟踪测试覆盖率, 但仅针对功能测试和 clickhouse-server. 它每天进行.
+We also track test coverage but only for functional tests and only for clickhouse-server. It is performed on daily basis.
 
 ## Tests for Tests
 
-有自动检测薄片测试. 它运行所有新测试100次(用于功能测试)或10次(用于集成测试). 如果至少有一次测试失败，它就被认为是脆弱的.
+There is automated check for flaky tests. It runs all new tests 100 times (for functional tests) or 10 times (for integration tests). If at least single time the test failed, it is considered flaky.
 
 ## Testflows
 
-[Testflows](https://testflows.com/) 是一个企业级的测试框架. Altinity 使用它进行一些测试, 我们在 CI 中运行这些测试.
+[Testflows](https://testflows.com/) is an enterprise-grade open-source testing framework, which is used to test a subset of ClickHouse.
 
-## Yandex 检查 (only for Yandex employees)
+## Test Automation {#test-automation}
 
-这些检查将ClickHouse代码导入到Yandex内部的单一存储库中, 所以ClickHouse代码库可以被Yandex的其他产品(YT和YDB)用作库. 请注意, clickhouse-server本身并不是由内部回购构建的, Yandex应用程序使用的是未经修改的开源构建的.
+We run tests with [GitHub Actions](https://github.com/features/actions).
 
-## 测试自动化 {#test-automation}
+Build jobs and tests are run in Sandbox on per commit basis. Resulting packages and test results are published in GitHub and can be downloaded by direct links. Artifacts are stored for several months. When you send a pull request on GitHub, we tag it as “can be tested” and our CI system will build ClickHouse packages (release, debug, with address sanitizer, etc) for you.
 
-我们使用 Yandex 内部 CI 和名为 "Sandbox" 的作业自动化系统运行测试.
+We do not use Travis CI due to the limit on time and computational power.
+We do not use Jenkins. It was used before and now we are happy we are not using Jenkins.
 
-在每次提交的基础上, 构建作业和测试都在沙箱中运行. 生成的包和测试结果发布在GitHub上, 可以通过直接链接下载. 产物要保存几个月. 当你在GitHub上发送一个pull请求时, 我们会把它标记为 "可以测试" , 我们的CI系统会为你构建ClickHouse包(发布、调试、使用地址清理器等).
-
-由于时间和计算能力的限制, 我们不使用 Travis CI.
-我们不用Jenkins. 以前用过, 现在我们很高兴不用Jenkins了.

-#### 升级时请注意: {#please-note-when-upgrading}
-
--   现在有更高的 MergeTree 设置默认值 `max_bytes_to_merge_at_max_space_in_pool` (要合并的数据部分的最大总大小, 以字节为单位): 它已从 100 GiB 增加到 150 GiB. 这可能会导致在服务器升级后运行大型合并, 从而导致磁盘子系统负载增加. 如果服务器上的可用空间小于正在运行的合并总量的两倍, 这将导致所有其他合并停止运行, 包括小数据部分的合并. 因此, INSERT 查询将失败并显示消息"合并的处理速度明显慢于插入." , 使用 `SELECT * FROM system.merges` 查询来监控情况. 您还可以在 `system.metrics` 表或 Graphite 中检查 `DiskSpaceReservedForMerge` 指标. 您不需要做任何事情来解决这个问题, 因为一旦大型合并完成, 问题就会自行解决. 如果您发现这不可接受, 您可以恢复 `max_bytes_to_merge_at_max_space_in_pool` 设置的先前值. 为此, 请转到 config.xml 中的 `<merge_tree>` 部分, 设置 ``` <merge_tree>``<max_bytes_to_merge_at_max_space_in_pool>107374182400</max_bytes_to_merge_at_max_space_in_pool> ``` 并重新启动服务器.

--   某些聚合函数 (例如 `groupArray()` ) 的运行时编译期间的错误.
-
-### ClickHouse 版本 1.1.54276, 2017-08-16 {#clickhouse-release-1-1-54276-2017-08-16}
-
-#### 新特征: {#new-features-4}
-
--   SELECT 查询添加了一个可选的 WITH 部分. 示例查询：`WITH 1+1 AS a SELECT a, a*a` .

--   合并大段 MergeTree 数据时显着减少内存消耗并提高性能.
--   显着提高了 ReplacingMergeTree 引擎的数据合并性能.
--   通过组合多个源插入提高了从分布式表进行异步插入的性能. 要启用此功能, 请使用设置 `distributed_directory_monitor_batch_inserts=1` .
-
-#### Backward Incompatible Changes: {#backward-incompatible-changes-1}
-
--   更改了数组 `groupArray(array_column)` 函数聚合状态的二进制格式.
-
-#### Complete List of Changes: {#complete-list-of-changes}
-

--   加速清理以从 ZooKeeper 中删除过时的数据.
--   集群 DDL 查询的多项改进和修复. 特别有趣的是新设置 `distributed_ddl_task_timeout`, 它限制了等待集群中服务器响应的时间. 如果 ddl 请求没有在所有主机上执行，响应将包含超时错误并且请求将以异步模式执行.
--   改进了服务器日志中堆栈跟踪的显示.
--   为压缩方法添加了 "none" 值.
--   您可以在 config.xml 中使用多个dictionaries_config 部分.
--   可以通过文件系统中的套接字连接到 MySQL.

--   对于 `Kafka` 表, 未传递可选的 `schema` 参数 (`Cap'n'Proto` 格式的模式). [Vojtech Splichal](https://github.com/ClickHouse/ClickHouse/pull/3150)
--   如果 ZooKeeper 服务器的集合具有接受连接但随后立即关闭它而不是响应握手的服务器, 则 ClickHouse 选择连接另一台服务器. 以前, 这会产生错误 `无法读取所有数据. 读取的字节数：0.预期的字节数：4`. 并且服务器无法启动. [8218cf3a](https://github.com/ClickHouse/ClickHouse/commit/8218cf3a5f39a43401953769d6d12a0bb8d29da9)
--   如果 ZooKeeper 服务器的集合包含 DNS 查询返回错误的服务器, 这些服务器将被忽略. [17b8e209](https://github.com/ClickHouse/ClickHouse/commit/17b8e209221061325ad7ba0539f03c6e65f87f29)
--   `VALUES` 格式插入数据时, 修复了 `Date` 和 `DateTime` 之间的类型转换 (如果 `input_format_values_interpret_expressions = 1`). 之前在Unix Epoch时间的天数数值和Unix时间戳之间进行了转换, 导致了意想不到的结果. [#3229](https://github.com/ClickHouse/ClickHouse/pull/3229)

--   `log_query_threads` 设置 (关于查询执行的每个线程的日志信息) 现在只有在 `log_queries` 选项 (关于查询的日志信息) 设置为 1 时才生效. 由于`log_query_threads` 选项默认启用, 即使查询日志被禁用, 有关线程的信息也会被记录. [#3241](https://github.com/ClickHouse/ClickHouse/pull/3241)
--   修复了分位数聚合函数分布式操作的错误 (错误信息`Not found column quantile...`). [292a8855](https://github.com/ClickHouse/ClickHouse/commit/292a885533b8e3b41ce8993867069d14cbd5a664)
--   修复了同时在 18.12.17 版本服务器和旧服务器的集群上工作时的兼容性问题. 对于具有固定长度和非固定长度的 GROUP BY 键的分布式查询, 如果有大量数据要聚合, 则返回的数据并不总是完全聚合 (两个不同的行包含相同的聚合键). [#3254](https://github.com/ClickHouse/ClickHouse/pull/3254)
--   如果查询仅包含测试中声明的部分替换，则修复了对  `clickhouse-performance-test` 中替换的处理. [#3263](https://github.com/ClickHouse/ClickHouse/pull/3263)

--   在`PREWHERE` 子句中添加了对缺少`arrayJoin` 的检查. 以前, 这会导致在执行查询时出现诸如 `Size ...不匹配` 或 `未知压缩方法` 之类的消息. [#3357](https://github.com/ClickHouse/ClickHouse/pull/3357)
--   修复了在用相应的 IN 表达式替换来自相等评估的 AND 链的优化后在极少数情况下可能发生的段错误. [liuyimin-bytedance](https://github.com/ClickHouse/ClickHouse/pull/3339)
--   对`clickhouse-benchmark` 的小修正: 以前, 客户端信息没有发送到服务器; 现在在关闭和限制迭代次数时更准确地计算执行的查询数. [#3351](https://github.com/ClickHouse/ClickHouse/pull/3351) [#3352](https://github.com/ClickHouse/ClickHouse/pull/3352)
-

--   运行查询时, 表值函数运行一次. 以前, `remote` 和 `mysql` 表值函数执行相同的查询两次以从远程服务器检索表结构.
--   使用了 `MkDocs` 文档生成器.
--   当您尝试删除其他列的 `DEFAULT` / `MATERIALIZED` 表达式所依赖的表列时, 抛出异常 (zhang2014).

--   添加了为 `groupArray` 聚合函数传递 `AggregateFunction` 类型参数的可能性 (这样你就可以创建一些聚合函数的状态数组).
--   删除了对聚合函数组合器的各种组合的限制. 例如, 您可以使用 `avgForEachIf` 和 `avgIfForEach` 聚合函数, 它们具有不同的行为.
--   `-ForEach` 聚合函数组合器针对多参数聚合函数的情况进行了扩展.
--   添加了对 `Nullable` 参数的聚合函数的支持, 即使在函数返回非 `Nullable` 结果的情况下 (由 Silviu Caragea 添加). 示例: `groupArray`、`groupUniqArray`、`topK`.
--   为 `clickhouse-client` 添加了 `max_client_network_bandwidth` (Kirill Shvakov).

-
-#### Bug 修复: {#bug-fixes-28}
-
--   在运行 `DROP` 或 `DETACH PARTITION` 查询后修复了重复数据删除. 在以前的版本中, 删除分区并再次插入相同的数据不起作用, 因为插入的块被认为是重复的.

-
-#### Build 改进: {#build-improvements-4}
-
--   `pbuilder` 工具用于构建. 构建过程几乎完全独立于构建宿主环境.
--   单个构建用于不同的操作系统版本. 软件包和二进制文件已与各种 Linux 系统兼容.
--   添加了 `clickhouse-test` 包. 它可用于运行功能测试.
--   源 tarball 现在可以发布到存储库. 它可用于在不使用 GitHub 的情况下重现构建.
--   添加了与 Travis CI 的有限集成. 由于 Travis 中构建时间的限制, 仅测试调试构建并运行有限的测试子集.
--   在默认版本中添加了对 `Cap'n'Proto` 的支持.
--   将文档来源的格式从 `Restricted Text` 更改为 `Markdown`.
--   添加了对 `systemd` (Vladimir Smirnov) 的支持. 由于与某些操作系统映像不兼容, 它默认被禁用, 可以手动启用.
--   对于动态代码生成, `clang` 和 `lld` 被嵌入到 `clickhouse` 二进制文件中. 它们也可以作为 `clickhouse clang` 和 `clickhouse lld` 调用.
--   从代码中删除了 GNU 扩展的使用. 启用了`-Wextra` 选项。 当使用 `clang` 构建时, 默认是 `libc++` 而不是 `libstdc++`.
--   提取了 `clickhouse_parsers` 和 `clickhouse_common_io` 库以加速各种工具的构建.
-
-#### 向后不兼容的更新: {#backward-incompatible-changes-11}
-
--   包含 `Nullable` 列的 `Log` 类型表中标记的格式以向后不兼容的方式进行了更改. 如果你有这些表, 你应该在启动新的服务器版本之前将它们转换为 `TinyLog` 类型. 为此, 请在 `metadata` 目录中相应的 `.sql` 文件中将 `ENGINE = Log` 替换为 `ENGINE = TinyLog`. 如果你的表没有 `Nullable` 列或者你的表的类型不是 `Log`, 那么你不需要做任何事情.
--   删除了 `experimental_allow_extended_storage_definition_syntax` 设置. 现在默认启用此功能.
--   `runningIncome` 函数被重命名为 `runningDifferenceStartingWithFirstvalue` 以避免混淆.
--   当在没有表的 FROM 之后直接指定 ARRAY JOIN 时, 删除了 `FROM ARRAY JOIN arr` 语法 (Amos Bird).
--   删除了仅用于演示目的的 `BlockTabSeparated` 格式.
--   更改了聚合函数 `varSamp`、`varPop`、`stddevSamp`、`stddevPop`、`covarSamp`、`covarPop`、`corr` 的状态格式. 如果您已将这些聚合函数的状态存储在表中 (使用 `AggregateFunction` 数据类型或具有相应状态的物化视图), 请写信至 clickhouse-feedback@yandex-team.com.
--   在以前的服务器版本中, 有一个未公开的功能: 如果聚合函数依赖于参数, 您仍然可以在 AggregateFunction 数据类型中不带参数地指定它. 示例: `AggregateFunction(quantiles, UInt64)` 而不是 `AggregateFunction(quantiles(0.5, 0.9), UInt64)` . 此功能已丢失. 虽然它没有记录, 但我们计划在未来的版本中再次支持它.
--   枚举数据类型不能用于最小/最大聚合函数. 此能力将在下一个版本中恢复.
-
-#### 升级时请注意: {#please-note-when-upgrading}
-
--   在集群上进行滚动更新时, 当一些副本运行旧版本的 ClickHouse 和一些运行新版本时, 复制会暂时停止, 并且日志中出现消息 `unknown parameter 'shard'` . 更新集群的所有副本后, 复制将继续.
--   如果在集群服务器上运行不同版本的 ClickHouse, 使用以下函数的分布式查询可能会得到不正确的结果: `varSamp`、`varPop`、`stddevSamp`、`stddevPop`、`covarSamp`、`covarPop` , `corr`. 您应该更新所有集群节点.

-
-#### Bug 修复
-
-* 当查询分析器打开并且 ClickHouse 安装在操作系统上时, 修复罕见的无声崩溃, glibc 版本已经 (据说) 损坏了某些功能的异步展开表. 这修复了 [#15301](https://github.com/ClickHouse/ClickHouse/issues/15301). This fixes [#13098](https://github.com/ClickHouse/ClickHouse/issues/13098). [#16846](https://github.com/ClickHouse/ClickHouse/pull/16846) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-
-
-### ClickHouse 版本 v20.11.2.1, 2020-11-11
-
-#### 向后不兼容变更
-
-* 如果在 `distributed_ddl` 配置部分指定了一些 `profile`, 那么这个配置文件可以在服务器启动时覆盖 `default` 配置文件的设置. 已修复, 现在分布式 DDL 查询的设置不应影响全局服务器设置. [#16635](https://github.com/ClickHouse/ClickHouse/pull/16635) ([tavplubix](https://github.com/tavplubix)).
-* 限制在键 (排序键、主键、分区键等) 中使用不可比较的数据类型 (如 `AggregateFunction`). [#16601](https://github.com/ClickHouse/ClickHouse/pull/16601) ([alesapin](https://github.com/alesapin)).
-* 删除 `ANALYZE` 和 `AST` 查询，并使设置 `enable_debug_queries` 过时, 因为它现在是全功能 `EXPLAIN` 查询的一部分. [#16536](https://github.com/ClickHouse/ClickHouse/pull/16536) ([Ivan](https://github.com/abyss7)).
-* 聚合函数 `boundingRatio`、`rankCorr`、`retention`、`timeSeriesGroupSum`、`timeSeriesGroupRateSum`、`windowFunnel` 被错误地设为不区分大小写. 现在他们的名字按照设计区分大小写.  只有在 SQL 标准中指定的函数或为了与其他 DBMS 兼容而制作的函数或与这些函数类似的函数才应不区分大小写. [#16407](https://github.com/ClickHouse/ClickHouse/pull/16407) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 使 `rankCorr` 函数在数据不足时返回 nan [#16124](https://github.com/ClickHouse/ClickHouse/issues/16124). [#16135](https://github.com/ClickHouse/ClickHouse/pull/16135) ([hexiaoting](https://github.com/hexiaoting)).
-* 从20.5以上的版本升级时, 如果进行滚动更新, 集群同时包含20.5以上和20.5以下的版本, 如果旧版本的ClickHouse节点重启, 旧版本在新版本存在的情况下启动, 可能会导致 到 `Part ... intersects previous part` 错误. 为防止出现此错误, 首先在所有集群节点上安装更新的 clickhouse-server 软件包, 然后重新启动 (因此，当 clickhouse-server 重新启动时, 它将以新版本启动).
-
-#### 新特征
-
-* 添加了对 LDAP 作为本地不存在用户的用户目录的支持. [#12736](https://github.com/ClickHouse/ClickHouse/pull/12736) ([Denis Glazachev](https://github.com/traceon)).
-* 添加 `system.replicated_fetches` 表, 显示当前正在运行的后台提取. [#16428](https://github.com/ClickHouse/ClickHouse/pull/16428) ([alesapin](https://github.com/alesapin)).

-* 添加了初始 OpenTelemetry 支持. ClickHouse 现在通过 Native 和 HTTP 协议接受 OpenTelemetry traceparent 标头, 并在某些情况下向下游传递它们. 执行查询的跟踪跨度保存到 `system.opentelemetry_span_log` 表中. [#14195](https://github.com/ClickHouse/ClickHouse/pull/14195) ([Alexander Kuzmenkov](https://github.com/akuzm)).
-* 允许在 `CREATE TABLE` 查询的列列表中指定主键. 这是与其他 SQL 方言兼容所必需的. [#15823](https://github.com/ClickHouse/ClickHouse/pull/15823) ([Maksim Kita](https://github.com/kitaisreal)).
-* 实现 `OFFSET offset_row_count {ROW | ROWS} FETCH {FIRST | NEXT} fetch_row_count {ROW | ROWS} {ONLY | WITH TIES}` 在带有 ORDER BY 的 SELECT 查询中. 这是指定 `LIMIT` 的SQL标准方式. [#15855](https://github.com/ClickHouse/ClickHouse/pull/15855) ([hexiaoting](https://github.com/hexiaoting)).
-* `errorCodeToName` 函数 - 返回错误的变量名称 (用于分析 query_log 和类似的). `system.errors` 表 - 显示错误发生的次数 (包括 `system_events_show_zero_values`). [#16438](https://github.com/ClickHouse/ClickHouse/pull/16438) ([Azat Khuzhin](https://github.com/azat)).
-* 添加了函数 `untuple`, 这是一个特殊的函数, 它可以通过扩展命名元组将新列引入到 SELECT 列表中. [#16242](https://github.com/ClickHouse/ClickHouse/pull/16242) ([Nikolai Kochetov](https://github.com/KochetovNicolai), [Amos Bird](https://github.com/amosbird)).
-* 现在我们可以通过查询参数提供标识符. 并且这些参数可以用作表对象或列. [#16594](https://github.com/ClickHouse/ClickHouse/pull/16594) ([Amos Bird](https://github.com/amosbird)).
-* 为 MergeTree BloomFilter 索引添加了大整数 (UInt256、Int128、Int256)和 UUID 数据类型支持. 大整数是一项实验性功能. [#16642](https://github.com/ClickHouse/ClickHouse/pull/16642) ([Maksim Kita](https://github.com/kitaisreal)).
-* 添加 `farmFingerprint64` 函数 (非加密字符串散列). [#16570](https://github.com/ClickHouse/ClickHouse/pull/16570) ([Jacob Hayes](https://github.com/JacobHayes)).
-* 添加 `log_queries_min_query_duration_ms`, 只有比这个设置的值慢的查询才会转到 `query_log`/`query_thread_log` (例如mysql中的 `slow_query_log` ). [#16529](https://github.com/ClickHouse/ClickHouse/pull/16529) ([Azat Khuzhin](https://github.com/azat)).
-* 能够在 `Alpine` 的顶部创建一个 docker 图像. 使用来自 ubuntu 20.04 的预编译二进制和 glibc 组件. [#16479](https://github.com/ClickHouse/ClickHouse/pull/16479) ([filimonov](https://github.com/filimonov)).
-* 添加了 `toUUIDOrNull`、`toUUIDOrZero` 转换函数. [#16337](https://github.com/ClickHouse/ClickHouse/pull/16337) ([Maksim Kita](https://github.com/kitaisreal)).
-* 添加 `max_concurrent_queries_for_all_users` 设置, 用例见 [#6636](https://github.com/ClickHouse/ClickHouse/issues/6636). [#16154](https://github.com/ClickHouse/ClickHouse/pull/16154) ([nvartolomei](https://github.com/nvartolomei)).
-* 向 clickhouse-client 添加一个新选项 `print_query_id`. 它有助于使用客户端生成的当前查询 ID 生成任意字符串. 默认情况下还会在 clickhouse-client 中打印查询 ID. [#15809](https://github.com/ClickHouse/ClickHouse/pull/15809) ([Amos Bird](https://github.com/amosbird)).
-* 添加 `tid` 和 `logTrace` 函数. 这将关闭 [#9434](https://github.com/ClickHouse/ClickHouse/issues/9434). [#15803](https://github.com/ClickHouse/ClickHouse/pull/15803) ([flynn](https://github.com/ucasFL)).
-* 添加函数 `formatReadableTimeDelta`, 将时间增量格式化为人类可读的字符串... [#15497](https://github.com/ClickHouse/ClickHouse/pull/15497) ([Filipe Caixeta](https://github.com/filipecaixeta)).
-* 在多磁盘配置中为卷添加了 `disable_merges` 选项. [#13956](https://github.com/ClickHouse/ClickHouse/pull/13956) ([Vladimir Chebotarev](https://github.com/excitoon)).
-
-#### 实验功能
-
-* 新函数 `encrypt`、`aes_encrypt_mysql`、`decrypt`、`aes_decrypt_mysql`. 这些功能运行缓慢, 因此我们将其视为实验性功能. [#11844](https://github.com/ClickHouse/ClickHouse/pull/11844) ([Vasily Nemkov](https://github.com/Enmk)).
-
-#### Bug 修复
-
-* 在 `system.distribution_queue` 中的data_path中屏蔽密码. [#16727](https://github.com/ClickHouse/ClickHouse/pull/16727) ([Azat Khuzhin](https://github.com/azat)).

-* 如果查询的表没有采样, 设置 `max_parallel_replicas` 将无法正常工作. 这修复了 [#5733](https://github.com/ClickHouse/ClickHouse/issues/5733). [#16675](https://github.com/ClickHouse/ClickHouse/pull/16675) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 使用 max_threads > 0 和 ORDER BY 中的表达式修复 optimize_read_in_order/optimize_aggregation_in_order. [#16637](https://github.com/ClickHouse/ClickHouse/pull/16637) ([Azat Khuzhin](https://github.com/azat)).
-* `DEFAULT` 表达式的计算涉及可能的名称冲突 (这是不太可能遇到的). 这修复了 [#9359](https://github.com/ClickHouse/ClickHouse/issues/9359). [#16612](https://github.com/ClickHouse/ClickHouse/pull/16612) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 修复 `query_thread_log.query_duration_ms` 单元. [#16563](https://github.com/ClickHouse/ClickHouse/pull/16563) ([Azat Khuzhin](https://github.com/azat)).
-* 修复使用 MySQL Master -> MySQL Slave -> ClickHouse MaterializeMySQL Engine 时的错误. `MaterializeMySQL` 是一个实验性功能. [#16504](https://github.com/ClickHouse/ClickHouse/pull/16504) ([TCeason](https://github.com/TCeason)).
-* 带有 `Decimal` 的 `round` 函数的特别设计参数导致整数除以零. 这修复了 [#13338](https://github.com/ClickHouse/ClickHouse/issues/13338). [#16451](https://github.com/ClickHouse/ClickHouse/pull/16451) ([alexey-milovidov](https://github.com/alexey-milovidov)).

-* 修复 [#15780](https://github.com/ClickHouse/ClickHouse/issues/15780) 回归, 例如 `indexOf([1, 2, 3], toLowCardinality(1))` 现在被禁止, 但不应该. [#16038](https://github.com/ClickHouse/ClickHouse/pull/16038) ([Mike](https://github.com/myrrc)).
-* 修复 MySQL 数据库的错误. 当用作数据库引擎的 MySQL 服务器关闭时, 某些查询会引发异常, 因为它们试图从禁用的服务器获取表, 而这是不必要的. 例如, 查询 `SELECT ... FROM system.parts` 应该只适用于 MergeTree 表并且根本不要接触 MySQL 数据库. [#16032](https://github.com/ClickHouse/ClickHouse/pull/16032) ([Kruglov Pavel](https://github.com/Avogar)).

-
-#### 改进
-
-* 将 `INTERVAL '1 hours'` 视为等同于 `INTERVAL 1 HOUR`, 以与 Postgres 和类似的兼容. 这修复了 [#15637](https://github.com/ClickHouse/ClickHouse/issues/15637). [#15978](https://github.com/ClickHouse/ClickHouse/pull/15978) ([flynn](https://github.com/ucasFL)).
-* 启用通过 CSV、TSV 和 JSON 输入格式的数字 ID 解析枚举值. [#15685](https://github.com/ClickHouse/ClickHouse/pull/15685) ([vivarum](https://github.com/vivarum)).

-* 在 `Avro` 格式中添加对 `LowCardinality` 的缺失支持. [#16521](https://github.com/ClickHouse/ClickHouse/pull/16521) ([Mike](https://github.com/myrrc)).
-* 将 `S3` 与 nginx 服务器一起用作代理的解决方法. Nginx 当前不接受像 `http://domain.com?delete` 这样的空路径 url, 但是 vanilla aws-sdk-cpp 会产生这种 url. 此提交使用修补过的 aws-sdk-cpp 版本, 在这种情况下, 它使 url 以"/"作为路径, 例如 `http://domain.com/?delete`. [#16814](https://github.com/ClickHouse/ClickHouse/pull/16814) ([ianton-ru](https://github.com/ianton-ru)).
-* 更好地诊断输入数据中的解析错误. 在 `Cannot read all data` 错误上提供行号. [#16644](https://github.com/ClickHouse/ClickHouse/pull/16644) ([alexey-milovidov](https://github.com/alexey-milovidov)).

-* 在运行时更好地更新 ZooKeeper 配置. [#16630](https://github.com/ClickHouse/ClickHouse/pull/16630) ([sundyli](https://github.com/sundy-li)).
-* 尽早应用 SETTINGS 子句. 它允许修改查询中的更多设置. 这将关闭 [#3178](https://github.com/ClickHouse/ClickHouse/issues/3178). [#16619](https://github.com/ClickHouse/ClickHouse/pull/16619) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 现在 `event_time_microseconds` 字段存储在 Decimal64 中, 而不是 UInt64. [#16617](https://github.com/ClickHouse/ClickHouse/pull/16617) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).

-* 添加 `allow_nondeterministic_optimize_skip_unused_shards` (允许在分片键中使用非确定性，如 `rand()` 或 `dictGet()`). [#16105](https://github.com/ClickHouse/ClickHouse/pull/16105) ([Azat Khuzhin](https://github.com/azat)).
-* 修复 `memory_profiler_step`/`max_untracked_memory` 以通过 HTTP 进行查询 (包括测试). 修复在 xml 配置中全局调整此值也无济于事的问题, 因为这些设置无论如何都不会应用, 只有默认 (4MB) 值是 [used](https://github.com/ClickHouse/ClickHouse/blob/17731245336d8c84f75e4c0894c5797ed7732190 /src/Common/ThreadStatus.h#L104). 修复 http 查询最根 ThreadStatus 的 `query_id` (通过在读取 query_id 后初始化 QueryScope). [#16101](https://github.com/ClickHouse/ClickHouse/pull/16101) ([Azat Khuzhin](https://github.com/azat)).

-### ClickHouse 版本 v20.10.4.1-stable, 2020-11-13
-
-#### Bug 修复
-
-* 当查询分析器打开并且 ClickHouse 安装在操作系统上时, 修复罕见的无声崩溃, glibc 版本已经 (据说) 损坏了某些功能的异步展开表. 这修复了 [#15301](https://github.com/ClickHouse/ClickHouse/issues/15301)。 这修复了 [#13098](https://github.com/ClickHouse/ClickHouse/issues/13098). [#16846](https://github.com/ClickHouse/ClickHouse/pull/16846) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 在启用了 `transform_null_in` 设置的情况下修复多个列和元组上的 `IN` 运算符. 修复 [#15310](https://github.com/ClickHouse/ClickHouse/issues/15310). [#16722](https://github.com/ClickHouse/ClickHouse/pull/16722) ([Anton Popov](https://github.com/CurtizJ)).
-* 这将修复 optimize_read_in_order/optimize_aggregation_in_order 与 max_threads>0 和 ORDER BY 中的表达式. [#16637](https://github.com/ClickHouse/ClickHouse/pull/16637) ([Azat Khuzhin](https://github.com/azat)).
-* 现在, 当从输入解析 AVRO 时, LowCardinality 从类型中删除. 修复 [#16188](https://github.com/ClickHouse/ClickHouse/issues/16188). [#16521](https://github.com/ClickHouse/ClickHouse/pull/16521) ([Mike](https://github.com/myrrc)).
-* 通过适当缩小 GTID 集, 修复使用 MySQL Master -> MySQL Slave -> ClickHouse MaterializeMySQL Engine 和 MySQL Slave 上启用的 `slave_parallel_worker` 时元数据的快速增长. 这修复了 [#15951](https://github.com/ClickHouse/ClickHouse/issues/15951). [#16504](https://github.com/ClickHouse/ClickHouse/pull/16504) ([TCeason](https://github.com/TCeason)).
-* 修复分布式的 DROP TABLE (使用 INSERT). [#16409](https://github.com/ClickHouse/ClickHouse/pull/16409) ([Azat Khuzhin](https://github.com/azat)).
-* 修复复制队列中非常大的条目的处理. 如果表结构非常大 (接近 1 MB), 则非常大的条目可能会出现在 ALTER 查询中. 这修复了 [#16307](https://github.com/ClickHouse/ClickHouse/issues/16307). [#16332](https://github.com/ClickHouse/ClickHouse/pull/16332) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 修复 MySQL 数据库的错误. 当用作数据库引擎的 MySQL 服务器关闭时, 某些查询会引发异常, 因为它们试图从禁用的服务器获取表, 而这是不必要的. 例如, 查询 `SELECT ... FROM system.parts` 应该只适用于 MergeTree 表并且根本不要接触 MySQL 数据库. [#16032](https://github.com/ClickHouse/ClickHouse/pull/16032) ([Kruglov Pavel](https://github.com/Avogar)).
-
-#### 改进
-
-* 将 S3 与 nginx 服务器一起用作代理的解决方法。 Nginx 当前不接受像 http://domain.com?delete 这样的空路径 url，但是 vanilla aws-sdk-cpp 会生成这种 url。 此提交使用修补过的 aws-sdk-cpp 版本，在这种情况下，它使 url 以“/”作为路径，例如 http://domain.com/?delete. [#16813](https://github.com/ClickHouse/ClickHouse/pull/16813) ([ianton-ru](https://github.com/ianton-ru)).

-
-### ClickHouse 版本 v20.10.3.30, 2020-10-28
-
-#### 向后不兼容变更
-
-* 使 `multiple_joins_rewriter_version` 过时. 删除连接重写器的第一个版本. [#15472](https://github.com/ClickHouse/ClickHouse/pull/15472) ([Artem Zuikov](https://github.com/4ertus2)).
-* 将 `format_regexp_escaping_rule` 设置的默认值 (它与 `Regexp` 格式相关) 更改为 `Raw` (这意味着 - 将整个子模式作为一个值读取), 使行为更符合用户的期望. [#15426](https://github.com/ClickHouse/ClickHouse/pull/15426) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 在 SQL 中添加对嵌套多行注释 `/* 注释 /* 注释 */ */` 的支持. 这符合SQL标准. [#14655](https://github.com/ClickHouse/ClickHouse/pull/14655) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 添加了 MergeTree 设置 (`max_replicated_merges_with_ttl_in_queue` 和 `max_number_of_merges_with_ttl_in_pool`) 来控制后台池和复制队列中与 TTL 合并的数量. 仅当您使用删除 TTL 时, 此更改才会破坏与旧版本的兼容性. 否则, 复制将保持兼容. 如果您一次更新所有分片副本或执行 `SYSTEM STOP TTL MERGES` 直到完成所有副本的更新, 您可以避免不兼容问题. 如果你在复制队列中得到一个不兼容的条目, 首先, 执行 `SYSTEM STOP TTL MERGES` , 然后在 `ALTER TABLE ... DETACH PARTITION ...` 分配不兼容的TTL合并的分区. 将其重新连接到单个副本上. [#14490](https://github.com/ClickHouse/ClickHouse/pull/14490) ([alesapin](https://github.com/alesapin)).
-* 从20.5以上的版本升级时, 如果进行滚动更新, 集群同时包含20.5以上和20.5以下的版本, 如果旧版本的ClickHouse节点重启, 旧版本在新版本存在的情况下启动, 可能会导致 `Part ... intersects previous part` 错误. 为防止出现此错误, 首先在所有集群节点上安装更新的 clickhouse-server 软件包, 然后重新启动 (因此, 当 clickhouse-server 重新启动时, 它将以新版本启动).

-
-#### 向后不兼容变更
-
-* 从20.5以上的版本升级时, 如果进行滚动更新, 集群同时包含20.5以上和20.5以下的版本, 如果旧版本的ClickHouse节点重启, 旧版本在新版本存在的情况下启动, 可能会导致 到 `Part ... intersects previous part` 错误. 为防止出现此错误, 首先在所有集群节点上安装更新的 clickhouse-server 软件包, 然后重新启动 (因此, 当 clickhouse-server 重新启动时, 它将以新版本启动).
-
-#### 新特征
-
-* 添加了列转换器`EXCEPT`、`REPLACE`、`APPLY`, 可以应用于所选列的列表 (在`*` 或`COLUMNS(...)` 之后). 例如, 您可以编写 `SELECT * EXCEPT(URL) REPLACE(number + 1 AS number)`. 另一个例子: `select * apply(length) apply(max) from wide_string_table` 找出所有字符串列的最大长度.

-
-#### Bug 修复
-

-### ClickHouse 版本 v20.8.2.3-stable, 2020-09-08
-
-#### 向后不兼容变更
-
-* 现在 `OPTIMIZE FINAL` 查询不会重新计算在创建 TTL 之前添加的部件的 TTL. 使用 `ALTER TABLE ... MATERIALIZE TTL` 一次来计算它们, 之后 `OPTIMIZE FINAL` 将正确评估TTL. 此行为从未适用于复制表. [#14220](https://github.com/ClickHouse/ClickHouse/pull/14220) ([alesapin](https://github.com/alesapin)).
-* 扩展 `parallel_distributed_insert_select` 设置, 添加一个选项以将 `INSERT` 运行到本地表中. 该设置将类型从 `Bool` 更改为 `UInt64`, 因此不再支持值 `false` 和 `true`. 如果服务器配置中有这些值, 服务器将不会启动. 请将它们分别替换为 `0` 和 `1`. [#14060](https://github.com/ClickHouse/ClickHouse/pull/14060) ([Azat Khuzhin](https://github.com/azat)).
-* 移除对 `ODBCDriver` 输入/输出格式的支持. 这是曾经用于与 ClickHouse ODBC 驱动程序通信的弃用格式, 现在早已被 `ODBCDriver2` 格式取代. 解决 [#13629](https://github.com/ClickHouse/ClickHouse/issues/13629). [#13847](https://github.com/ClickHouse/ClickHouse/pull/13847) ([hexiaoting](https://github.com/hexiaoting)).
-* 从20.5以上的版本升级时, 如果进行滚动更新, 集群同时包含20.5以上和20.5以下的版本, 如果旧版本的ClickHouse节点重启, 旧版本在新版本存在的情况下启动, 可能会导致 `Part ... intersects previous part` 错误. 为防止出现此错误, 首先在所有集群节点上安装更新的 clickhouse-server 软件包, 然后重新启动 (因此，当 clickhouse-server 重新启动时, 它将以新版本启动).
-
-#### 新特征
-
-* 添加为与 `config.xml` 中指定的设置相对应的列指定 `Default` 压缩编解码器的功能. 实现: [#9074](https://github.com/ClickHouse/ClickHouse/issues/9074). [#14049](https://github.com/ClickHouse/ClickHouse/pull/14049) ([alesapin](https://github.com/alesapin)).

-* 添加 `quantileExactLow` 和 `quantileExactHigh` 实现, 并分别具有 `medianExactLow` 和 `medianExactHigh` 的别名. [#13818](https://github.com/ClickHouse/ClickHouse/pull/13818) ([Bharat Nallan](https://github.com/bharatnc)).
-* 添加了将日期/时间值截断为指定日期/时间部分的 `date_trunc` 函数. [#13888](https://github.com/ClickHouse/ClickHouse/pull/13888) ([Vladimir Golovchenko](https://github.com/vladimir-golovchenko)).

-
-#### 改进
-
-* 在 `ALIAS` 列类型上不允许使用 `CODEC`. 修复 [#13911](https://github.com/ClickHouse/ClickHouse/issues/13911). [#14263](https://github.com/ClickHouse/ClickHouse/pull/14263) ([Bharat Nallan](https://github.com/bharatnc)).
-* 等待字典更新完成时, 使用由 `query_wait_timeout_milliseconds` 设置指定的超时而不是硬编码值. [#14105](https://github.com/ClickHouse/ClickHouse/pull/14105) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* 添加设置 `min_index_granularity_bytes` 以防止意外创建具有非常低的 `index_granularity_bytes` 设置的表. [#14139](https://github.com/ClickHouse/ClickHouse/pull/14139) ([Bharat Nallan](https://github.com/bharatnc)).
-* 现在可以从使用不同 ZooKeeper 的集群中获取分区: `ALTER TABLE table_name FETCH PARTITION partition_expr FROM 'zk-name:/path-in-zookeeper'`. 这对于将数据传送到新集群很有用. [#14155](https://github.com/ClickHouse/ClickHouse/pull/14155) ([Amos Bird](https://github.com/amosbird)).
-* 如果 Memory 表是由大量非常小的块构建的, 那么它的性能会稍好一些 (这不太可能). 这个想法的作者: [Mark Papadakis](https://github.com/markpapadakis). 关闭 [#14043](https://github.com/ClickHouse/ClickHouse/issues/14043). [#14056](https://github.com/ClickHouse/ClickHouse/pull/14056) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 条件聚合函数 (例如: `avgIf`、`sumIf`、`maxIf`) 在缺少行并使用可为空参数时应返回 `NULL` . [#13964](https://github.com/ClickHouse/ClickHouse/pull/13964) ([Winter Zhang](https://github.com/zhang2014)).
-* 将 -Resample 组合器中的限制增加到 1M. [#13947](https://github.com/ClickHouse/ClickHouse/pull/13947) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
-* 更正了 AvroConfluent 格式的错误, 该错误导致 Kafka 表引擎在收到异常小的、格式错误的消息时停止处理消息. [#13941](https://github.com/ClickHouse/ClickHouse/pull/13941) ([Gervasio Varela](https://github.com/gervarela)).
-* 修复长查询的错误错误. 为了正确查询, 可能会出现除 `Max query size exceeded` 之外的语法错误. [#13928](https://github.com/ClickHouse/ClickHouse/pull/13928) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
-* `TabSeparated` 格式的空值的更好的错误消息. [#13906](https://github.com/ClickHouse/ClickHouse/pull/13906) ([jiang tao](https://github.com/tomjiang1987)).
-* 如果数组元素的类型是 Float32/Float64, 函数 `arrayCompact` 将按位比较 NaN. 在以前的版本中, 如果数组元素的类型是 Float32/Float64，NaN 总是不相等, 如果类型更复杂, 例如 Nullable(Float64), NaN 总是相等. 这将关闭 [#13857](https://github.com/ClickHouse/ClickHouse/issues/13857). [#13868](https://github.com/ClickHouse/ClickHouse/pull/13868) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 修复 `lgamma` 函数中的数据竞争. 这场比赛只在 `tsan` 中被抓到, 没有真正发生过副作用. [#13842](https://github.com/ClickHouse/ClickHouse/pull/13842) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
-* 当数组作为字段操作时, 避免太慢的查询. 改为抛出异常. [#13753](https://github.com/ClickHouse/ClickHouse/pull/13753) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 新增Redis requirepass授权 (针对redis字典源码). [#13688](https://github.com/ClickHouse/ClickHouse/pull/13688) ([Ivan Torgashov](https://github.com/it1804)).
-* 添加 MergeTree Write-Ahead-Log (WAL) 转储工具. WAL 是一个实验性功能. [#13640](https://github.com/ClickHouse/ClickHouse/pull/13640) ([BohuTANG](https://github.com/BohuTANG)).
-* 在以前的版本中, 如果使用专门设计的参数调用, `lcm` 函数可能会在调试构建中产生断言冲突. 这修复了 [#13368](https://github.com/ClickHouse/ClickHouse/issues/13368). [#13510](https://github.com/ClickHouse/ClickHouse/pull/13510) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 在更多情况下为 `toDate/toDateTime` 函数提供单调性. 单调性信息用于索引分析 (更复杂的查询将能够使用索引). 现在输入参数更自然地饱和并提供更好的单调性. [#13497](https://github.com/ClickHouse/ClickHouse/pull/13497) ([Amos Bird](https://github.com/amosbird)).
-* 支持自定义设置的复合标识符. 自定义设置是 ClickHouse 代码库与其他代码库的集成点 (对 ClickHouse 本身没有好处) [#13496](https://github.com/ClickHouse/ClickHouse/pull/13496) ([Vitaly Baranov](https://github.com/vitlibar)).
-* 将部分从 DiskLocal 并行移动到 DiskS3. `DiskS3` 是一个实验性功能. [#13459](https://github.com/ClickHouse/ClickHouse/pull/13459) ([Pavel Kovalenko](https://github.com/Jokser)).
-* 默认启用混合粒度部分. [#13449](https://github.com/ClickHouse/ClickHouse/pull/13449) ([alesapin](https://github.com/alesapin)).
-* S3 重定向中正确的远程主机检查 (与安全相关的事情). [#13404](https://github.com/ClickHouse/ClickHouse/pull/13404) ([Vladimir Chebotarev](https://github.com/excitoon)).
-* 将 `QueryTimeMicroseconds`、`SelectQueryTimeMicroseconds` 和 `InsertQueryTimeMicroseconds` 添加到 system.events. [#13336](https://github.com/ClickHouse/ClickHouse/pull/13336) ([ianton-ru](https://github.com/ianton-ru)).
-* 修复 Decimal 具有太大负指数时的调试断言. 修复 [#13188](https://github.com/ClickHouse/ClickHouse/issues/13188). [#13228](https://github.com/ClickHouse/ClickHouse/pull/13228) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 为 DiskS3 添加了缓存层 (缓存到本地磁盘标记和索引文件). `DiskS3` 是一个实验性功能. [#13076](https://github.com/ClickHouse/ClickHouse/pull/13076) ([Pavel Kovalenko](https://github.com/Jokser)).
-* 修复 readline 以便现在将历史记录转储到文件中. [#13600](https://github.com/ClickHouse/ClickHouse/pull/13600) ([Amos Bird](https://github.com/amosbird)).
-* 默认使用 `Atomic` 引擎创建 `system` 数据库 (准备在任何地方默认启用 `Atomic` 数据库引擎). [#13680](https://github.com/ClickHouse/ClickHouse/pull/13680) ([tavplubix](https://github.com/tavplubix)).
-
-#### 性能改进
-
-* 使用 `LowCardinality` 稍微优化非常短的查询. [#14129](https://github.com/ClickHouse/ClickHouse/pull/14129) ([Anton Popov](https://github.com/CurtizJ)).
-* 当设置 `max_insert_threads` 时, 为表引擎 `Null`、`Memory`、`Distributed` 和 `Buffer` 启用并行插入. [#14120](https://github.com/ClickHouse/ClickHouse/pull/14120) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 如果在部件扫描时超过 `max_rows_to_read` 限制, 则快速失败. 此更改背后的动机是, 如果明显已超过 `max_rows_to_read`, 则跳过所有选定部分的范围扫描. 对于大量零件的查询, 这种变化非常明显. [#13677](https://github.com/ClickHouse/ClickHouse/pull/13677) ([Roman Khavronenko](https://github.com/hagen1778)).
-* 通过 UInt8/UInt16 键略微提高聚合性能. [#13099](https://github.com/ClickHouse/ClickHouse/pull/13099) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 优化`has()`、`indexOf()`和 `countEqual()` 函数, 用于 `Array(LowCardinality(T))` 和常量右参数. [#12550](https://github.com/ClickHouse/ClickHouse/pull/12550) ([myrrc](https://github.com/myrrc)).
-* 在执行简单的 `INSERT SELECT` 查询时, 自动将 `max_threads` 设置为1 或 `max_insert_threads`, 并将 `max_block_size` 设置为 `min_insert_block_size_rows`. 相关 [#5907](https://github.com/ClickHouse/ClickHouse/issues/5907). [#12195](https://github.com/ClickHouse/ClickHouse/pull/12195) ([flynn](https://github.com/ucasFL)).
-
-#### 实验功能
-
-* ClickHouse 可以用作 MySQL 副本 - 它由 `MaterializeMySQL` 数据库引擎实现. 实现 [#4006](https://github.com/ClickHouse/ClickHouse/issues/4006). [#10851](https://github.com/ClickHouse/ClickHouse/pull/10851) ([Winter Zhang](https://github.com/zhang2014)).
-* 为它们添加类型 `Int128`、`Int256`、`UInt256` 和相关函数. 使用 Decimal256 扩展小数 (精度高达 76 位). 新类型在设置 `allow_experimental_bigint_types` 下. 它的工作非常缓慢和糟糕. 实施不完整. 请不要使用此功能. [#13097](https://github.com/ClickHouse/ClickHouse/pull/13097) ([Artem Zuikov](https://github.com/4ertus2)).
-
-#### 构建/测试/打包改进
-
-* 添加了 `clickhouse install` 脚本, 如果你只有一个二进制文件, 这很有用. [#13528](https://github.com/ClickHouse/ClickHouse/pull/13528) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 允许在没有配置的情况下运行 `clickhouse` 二进制文件. [#13515](https://github.com/ClickHouse/ClickHouse/pull/13515) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 使用 `codespell` 启用检查代码中的拼写错误. [#13513](https://github.com/ClickHouse/ClickHouse/pull/13513) [#13511](https://github.com/ClickHouse/ClickHouse/pull/13511) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 在 CI 中启用 Shellcheck 作为 .sh 测试的 linter. 这将关闭 [#13168](https://github.com/ClickHouse/ClickHouse/issues/13168). [#13530](https://github.com/ClickHouse/ClickHouse/pull/13530) [#13529](https://github.com/ClickHouse/ClickHouse/pull/13529) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 添加 CMake 选项以失败配置而不是自动重新配置, 默认启用. [#13687](https://github.com/ClickHouse/ClickHouse/pull/13687) ([Konstantin](https://github.com/podshumok)).
-* 通过 system.build_options 中的 TZDATA_VERSION 公开嵌入式 tzdata 的版本. [#13648](https://github.com/ClickHouse/ClickHouse/pull/13648) ([filimonov](https://github.com/filimonov)).
-* 在构建期间改进 system.time_zones 表的生成. 关闭 [#14209](https://github.com/ClickHouse/ClickHouse/issues/14209). [#14215](https://github.com/ClickHouse/ClickHouse/pull/14215) ([filimonov](https://github.com/filimonov)).
-* 使用来自包存储库的最新 tzdata 构建 ClickHouse. [#13623](https://github.com/ClickHouse/ClickHouse/pull/13623) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 在skip_list.json中添加编写js样式注释的能力. [#14159](https://github.com/ClickHouse/ClickHouse/pull/14159) ([alesapin](https://github.com/alesapin)).
-* 确保没有复制粘贴的 GPL 代码. [#13514](https://github.com/ClickHouse/ClickHouse/pull/13514) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 切换测试 docker 图像以使用基于测试的父级. [#14167](https://github.com/ClickHouse/ClickHouse/pull/14167) ([Ilya Yatsishin](https://github.com/qoega)).
-* 启动docker-compose集群时添加重试逻辑; 增加 COMPOSE_HTTP_TIMEOUT. [#14112](https://github.com/ClickHouse/ClickHouse/pull/14112) ([vzakaznikov](https://github.com/vzakaznikov)).
-* 在压力测试中启用 `system.text_log` 以发现更多错误. [#13855](https://github.com/ClickHouse/ClickHouse/pull/13855) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* Testflows LDAP 模块: 为 openldap4 添加缺少的证书和 dhparam.pem. [#13780](https://github.com/ClickHouse/ClickHouse/pull/13780) ([vzakaznikov](https://github.com/vzakaznikov)).
-* ZooKeeper 在 CI 基础设施的单元测试中无法可靠地工作. 使用单元测试进行 ZooKeeper 与真正的 ZooKeeper 交互从一开始就是个坏主意 (单元测试不应该验证复杂的分布式系统). 我们已经为此目的使用集成测试, 它们更适合. [#13745](https://github.com/ClickHouse/ClickHouse/pull/13745) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 添加了用于样式检查的 docker 图像. 添加样式检查所有 docker 和 docker compose 文件都位于 docker 目录中. [#13724](https://github.com/ClickHouse/ClickHouse/pull/13724) ([Ilya Yatsishin](https://github.com/qoega)).
-* 修复 Mac OS 上的 cassandra 构建. [#13708](https://github.com/ClickHouse/ClickHouse/pull/13708) ([Ilya Yatsishin](https://github.com/qoega)).
-* 修复共享构建中的链接错误. [#13700](https://github.com/ClickHouse/ClickHouse/pull/13700) ([Amos Bird](https://github.com/amosbird)).
-* 更新 LDAP 用户身份验证套件以检查它是否适用于 RBAC. [#13656](https://github.com/ClickHouse/ClickHouse/pull/13656) ([vzakaznikov](https://github.com/vzakaznikov)).
-* 删除了 `contrib/aws` 的 `-DENABLE_CURL_CLIENT`. [#13628](https://github.com/ClickHouse/ClickHouse/pull/13628) ([Vladimir Chebotarev](https://github.com/excitoon)).
-* 增加 ClickHouse 节点的运行状况检查超时, 并在发现不健康的容器时添加对转储 docker-compose 日志的支持. [#13612](https://github.com/ClickHouse/ClickHouse/pull/13612) ([vzakaznikov](https://github.com/vzakaznikov)).
-* 确保 [#10977](https://github.com/ClickHouse/ClickHouse/issues/10977) 无效. [#13539](https://github.com/ClickHouse/ClickHouse/pull/13539) ([Amos Bird](https://github.com/amosbird)).

-## ClickHouse 版本 20.7
-
-### ClickHouse 版本 v20.7.2.30-stable, 2020-08-31
-
-#### 向后不兼容变更
-
-* 以至少一个浮点数作为参数的函数 `modulo` (运算符 `%` )将直接计算浮点数的除法余数, 而不将两个参数都转换为整数. 它使行为与大多数 DBMS 兼容. 这也适用于 Date 和 DateTime 数据类型. 添加别名 `mod` . 这将关闭 [#7323](https://github.com/ClickHouse/ClickHouse/issues/7323). [#12585](https://github.com/ClickHouse/ClickHouse/pull/12585) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 弃用零日期/日期时间值的特殊打印为 `0000-00-00` 和`0000-00-00 00:00:00`. [#12442](https://github.com/ClickHouse/ClickHouse/pull/12442) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 函数 `groupArrayMoving*` 不适用于分布式查询. 它的结果是在不正确的数据类型中计算的 (没有升级到最大的类型). `groupArrayMovingAvg` 函数返回的整数与 `avg` 函数不一致. 这修复了[#12568](https://github.com/ClickHouse/ClickHouse/issues/12568). [#12622](https://github.com/ClickHouse/ClickHouse/pull/12622) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 为 MergeTree 设置添加健全性检查. 如果设置不正确，服务器将拒绝启动或创建表, 并向用户打印详细说明. [#13153](https://github.com/ClickHouse/ClickHouse/pull/13153) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 防止用户可能将 `background_pool_size` 设置为低于 `number_of_free_entries_in_pool_to_execute_mutation` 或 `number_of_free_entries_in_pool_to_lower_max_size_of_merge` 的值. 在这些情况下, ALTER 将不起作用或合并的最大大小将太有限. 它将抛出异常解释要做什么. 这将关闭 [#10897](https://github.com/ClickHouse/ClickHouse/issues/10897). [#12728](https://github.com/ClickHouse/ClickHouse/pull/12728) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 从20.5以上的版本升级时, 如果进行滚动更新, 集群同时包含20.5以上和20.5以下的版本, 如果旧版本的ClickHouse节点重启, 旧版本在新版本存在的情况下启动, 可能会导致 `Part ... intersects previous part` 错误. 为防止出现此错误, 首先在所有集群节点上安装更新的 clickhouse-server 软件包, 然后重新启动 (因此, 当 clickhouse-server 重新启动时, 它将以新版本启动).
-
-#### 新特征
-
-* 提供高效 `reverse geocoding` 查找的多边形字典类型 - 在许多多边形的字典 (世界地图) 中通过坐标查找区域. 它使用精心优化的算法和递归网格来保持较低的 CPU 和内存使用率. [#9278](https://github.com/ClickHouse/ClickHouse/pull/9278) ([achulkov2](https://github.com/achulkov2)).
-* 添加了对预配置用户的 LDAP 身份验证支持 ( `Simple Bind` 方法). [#11234](https://github.com/ClickHouse/ClickHouse/pull/11234) ([Denis Glazachev](https://github.com/traceon)).
-* 引入设置 `alter_partition_verbose_result`, 它为某些类型的 `ALTER TABLE ... PARTITION ...` 查询 (当前是`ATTACH` 和`FREEZE`)输出有关触摸部分的信息. 关闭 [#8076](https://github.com/ClickHouse/ClickHouse/issues/8076). [#13017](https://github.com/ClickHouse/ClickHouse/pull/13017) ([alesapin](https://github.com/alesapin)).
-* 为 bayesian-ab-testing 添加 `bayesAB` 函数. [#12327](https://github.com/ClickHouse/ClickHouse/pull/12327) ([achimbab](https://github.com/achimbab)).
-* 添加了 `system.crash_log` 表, 用于收集致命错误的堆栈跟踪. 这个表应该是空的. [#12316](https://github.com/ClickHouse/ClickHouse/pull/12316) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 添加了 http 标头 `X-ClickHouse-Database` 和 `X-ClickHouse-Format`, 可用于设置默认数据库和输出格式. [#12981](https://github.com/ClickHouse/ClickHouse/pull/12981) ([hcz](https://github.com/hczhcz)).
-* 将 `minMap` 和 `maxMap` 函数支持添加到 `SimpleAggregateFunction`. [#12662](https://github.com/ClickHouse/ClickHouse/pull/12662) ([Ildus Kurbangaliev](https://github.com/ildus)).
-* 添加设置 `allow_non_metadata_alters`, 它限制执行修改磁盘上数据的 `ALTER` 查询. 默认禁用. 关闭 [#11547](https://github.com/ClickHouse/ClickHouse/issues/11547). [#12635](https://github.com/ClickHouse/ClickHouse/pull/12635) ([alesapin](https://github.com/alesapin)).
-* 添加了一个函数 `formatRow` 以支持通过给定格式将任意表达式转换为字符串. 它对于操作 SQL 输出很有用, 并且与 `columns` 函数结合使用非常通用. [#12574](https://github.com/ClickHouse/ClickHouse/pull/12574) ([Amos Bird](https://github.com/amosbird)).
-* 添加 `FROM_UNIXTIME` 函数以兼容 MySQL, 与 [12149](https://github.com/ClickHouse/ClickHouse/issues/12149) 相关. [#12484](https://github.com/ClickHouse/ClickHouse/pull/12484) ([flynn](https://github.com/ucasFL)).

-
-#### 构建/测试/打包改进
-

-
-
-### ClickHouse 版本 v20.5.2.7-stable 2020-07-02
-
-#### 向后不兼容变更
-
-* 从 COUNT(DISTINCT) 和 `uniq` 聚合函数系列返回不可为空的结果. 如果所有传递的值都是 NULL, 则返回零. 这提高了 SQL 兼容性. [#11661](https://github.com/ClickHouse/ClickHouse/pull/11661) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 添加了对在错误位置指定用户级设置的情况的检查. 用户级设置应该在 `<profile>` 部分内的 `users.xml` 中为特定用户配置文件指定 (或在 `<default>` 中指定默认设置). 服务器不会以日志中的异常消息启动. 这修复了 [#9051](https://github.com/ClickHouse/ClickHouse/issues/9051). 如果您想跳过检查, 您可以将设置移动到适当的位置或将 `<skip_check_for_incorrect_settings>1</skip_check_for_incorrect_settings>` 添加到 config.xml. [#11449](https://github.com/ClickHouse/ClickHouse/pull/11449) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 默认情况下启用设置 `input_format_with_names_use_header`. 它会影响对输入格式 `-WithNames` 和 `-WithNamesAndTypes` 的解析. [#10937](https://github.com/ClickHouse/ClickHouse/pull/10937) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 删除 `experimental_use_processors` 设置. 它默认启用. [#10924](https://github.com/ClickHouse/ClickHouse/pull/10924) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
-* 将 `zstd` 更新到 1.4.4. 它在性能和压缩比方面有一些小的改进. 如果您使用不同版本的 ClickHouse 运行副本, 您可能会看到合理的错误消息 `Data after merge is not byte-identical to data on another replicas.`  并附有说明. 这些消息没问题, 您不必担心. 此更改向后兼容, 但我们将其列在更改日志中, 以防您对这些消息感到疑惑. [#10663](https://github.com/ClickHouse/ClickHouse/pull/10663) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 添加了对无意义编解码器的检查和设置 `allow_suspicious_codecs` 来控制此检查. 这将关闭 [#4966](https://github.com/ClickHouse/ClickHouse/issues/4966). [#10645](https://github.com/ClickHouse/ClickHouse/pull/10645) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* 一些 Kafka 设置更改了它们的默认值. 见 [#11388](https://github.com/ClickHouse/ClickHouse/pull/11388).
-* 从20.5以上的版本升级时, 如果进行滚动更新, 集群同时包含20.5以上和20.5以下的版本, 如果旧版本的ClickHouse节点重新启动, 旧版本在新版本存在的情况下启动, 可能会导致 `Part ... intersects previous part` 错误. 为防止出现此错误, 首先在所有集群节点上安装更新的 clickhouse-server 软件包, 然后重新启动 (因此, 当 clickhouse-server 重新启动时, 它将以新版本启动).
-
-#### 新特征

-
-
-### ClickHouse 版本 v20.3.3.6, 2020-03-17
-
-#### Bug 修复
-* 此版本还包含 20.1.7.38 的所有错误修复.
-* 修复复制中的错误, 如果用户在以前的版本上执行了更改, 则不允许复制工作. 这修复了 [#9645](https://github.com/ClickHouse/ClickHouse/issues/9645). [#9652](https://github.com/ClickHouse/ClickHouse/pull/9652) ([alesapin](https://github.com/alesapin)). It makes version 20.3 backward compatible again.

-
-### ClickHouse 版本 v20.3.2.1, 2020-03-12
-
-#### 向后不兼容变更
-
-* 修复了为大量副本的 `Distributed` 表发送数据时 `file name too long` 的问题. 修复了副本凭据在服务器日志中暴露的问题. 磁盘目录名格式改为 `[shard{shard_index}[_replica{replica_index}]]`. [#8911](https://github.com/ClickHouse/ClickHouse/pull/8911) ([Mikhail Korotov](https://github.com/millb)) 升级到新版本后, 您将不会无需人工干预即可降级, 因为旧服务器版本无法识别新目录格式. 如果要降级, 则必须手动将相应目录重命名为旧格式. 仅当您对 `Distributed` 表使用异步 `INSERT` 时, 此更改才相关. 在 20.3.3 版本中, 我们将引入一个设置, 允许您逐步启用新格式.
-* 更改了突变命令的复制日志条目的格式. 在安装新版本之前, 您必须等待旧的突变处理.
-* 实现简单的内存分析器, 在超过软分配限制 [#8765](https://github.com/ClickHouse/ClickHouse/pull/8765) ([Ivan](https:// github.com/abyss7)) [#9472](https://github.com/ClickHouse/ClickHouse/pull/9472) ([alexey-milovidov](https://github.com/alexey-milovidov)) 专栏 `system.trace_log` 的内容从 `timer_type` 重命名为 `trace_type`. 这将需要更改第三方性能分析和火焰图处理工具.
-* 在任何地方使用 OS 线程 id 而不是内部线程号. 这修复了 [#7477](https://github.com/ClickHouse/ClickHouse/issues/7477) 当启用设置 `send_logs_level` 时, 旧的 `clickhouse-client` 无法接收从服务器发送的日志, 因为名称和结构化日志消息的类型已更改. 另一方面, 不同的服务器版本可以相互发送不同类型的日志. 当你不使用 `send_logs_level` 设置时, 你应该不在乎. [#8954](https://github.com/ClickHouse/ClickHouse/pull/8954) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* 移除 `indexHint` 函数. [#9542](https://github.com/ClickHouse/ClickHouse/pull/9542) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* 移除 `findClusterIndex`、`findClusterValue` 函数. 这修复了 [#8641](https://github.com/ClickHouse/ClickHouse/issues/8641). 如果您正在使用这些功能, 请发送电子邮件至 `clickhouse-feedback@yandex-team.com`. [#9543](https://github.com/ClickHouse/ClickHouse/pull/9543) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* 现在不允许使用 `SELECT` 子查询作为默认表达式创建列或添加列. [#9481](https://github.com/ClickHouse/ClickHouse/pull/9481) ([alesapin](https://github.com/alesapin))
-* JOIN 中的子查询需要别名. [#9274](https://github.com/ClickHouse/ClickHouse/pull/9274) ([Artem Zuikov](https://github.com/4ertus2))
-* 改进了 `ALTER MODIFY/ADD` 查询逻辑. 现在你不能在没有类型的情况下 `ADD` 列, `MODIFY` 默认表达式不会改变列的类型, `MODIFY` 类型不会丢失默认表达式值. 修复 [#8669](https://github.com/ClickHouse/ClickHouse/issues/8669). [#9227](https://github.com/ClickHouse/ClickHouse/pull/9227) ([alesapin](https://github.com/alesapin))

-### ClickHouse 版本 v20.1.2.4, 2020-01-22
-
-#### 向后不兼容变更
-* 使设置 `merge_tree_uniform_read_distribution` 过时. 服务器仍然可以识别此设置, 但没有效果. [#8308](https://github.com/ClickHouse/ClickHouse/pull/8308) ([alexey-milovidov](https://github.com/alexey-milovidov))

-* 为与 `JOIN` 操作一致的 `StorageJoin` 添加新的 `ANY JOIN` 逻辑. 要在不改变行为的情况下进行升级, 您需要将 `SETTINGS any_join_distinct_right_table_keys = 1` 添加到引擎连接表元数据或在升级后重新创建这些表. [#8400](https://github.com/ClickHouse/ClickHouse/pull/8400) ([Artem Zuikov](https://github.com/4ertus2))
-* 需要重新启动服务器以应用日志配置中的更改. 这是一个临时解决方法, 以避免服务器记录到已删除的日志文件的错误 (请参阅 [#8696](https://github.com/ClickHouse/ClickHouse/issues/8696)). [#8707](https://github.com/ClickHouse/ClickHouse/pull/8707) ([Alexander Kuzmenkov](https://github.com/akuzm))
