+
+#### Backward Incompatible Change
+* Rename cache commands: `show caches` -> `show filesystem caches`, `describe cache` -> `describe filesystem cache`. [#41508](https://github.com/ClickHouse/ClickHouse/pull/41508) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Remove support for the `WITH TIMEOUT` section for `LIVE VIEW`. This closes [#40557](https://github.com/ClickHouse/ClickHouse/issues/40557). [#42173](https://github.com/ClickHouse/ClickHouse/pull/42173) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Remove support for the `{database}` macro from the client's prompt. It was displayed incorrectly if the database was unspecified and it was not updated on `USE` statements. This closes [#25891](https://github.com/ClickHouse/ClickHouse/issues/25891). [#42508](https://github.com/ClickHouse/ClickHouse/pull/42508) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Composable protocol configuration is added. Now different protocols can be set up with different listen hosts. Protocol wrappers such as PROXYv1 can be set up over any other protocols (TCP, TCP secure, MySQL, Postgres). [#41198](https://github.com/ClickHouse/ClickHouse/pull/41198) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Add `S3` as a new type of the destination of backups. Support BACKUP to S3 with as-is path/data structure. [#42333](https://github.com/ClickHouse/ClickHouse/pull/42333) ([Vitaly Baranov](https://github.com/vitlibar)), [#42232](https://github.com/ClickHouse/ClickHouse/pull/42232) ([Azat Khuzhin](https://github.com/azat)).
+* Added functions (`randUniform`, `randNormal`, `randLogNormal`, `randExponential`, `randChiSquared`, `randStudentT`, `randFisherF`, `randBernoulli`, `randBinomial`, `randNegativeBinomial`, `randPoisson`) to generate random values according to the specified distributions. This closes [#21834](https://github.com/ClickHouse/ClickHouse/issues/21834). [#42411](https://github.com/ClickHouse/ClickHouse/pull/42411) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* An improvement for ClickHouse Keeper: add support for uploading snapshots to S3. S3 information can be defined inside `keeper_server.s3_snapshot`. [#41342](https://github.com/ClickHouse/ClickHouse/pull/41342) ([Antonio Andelic](https://github.com/antonio2368)).
+* Added an aggregate function `analysisOfVariance` (`anova`) to perform a statistical test over several groups of normally distributed observations to find out whether all groups have the same mean or not. Original PR [#37872](https://github.com/ClickHouse/ClickHouse/issues/37872). [#42131](https://github.com/ClickHouse/ClickHouse/pull/42131) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Support limiting of temporary data stored on disk using settings `max_temporary_data_on_disk_size_for_user`/`max_temporary_data_on_disk_size_for_query` . [#40893](https://github.com/ClickHouse/ClickHouse/pull/40893) ([Vladimir C](https://github.com/vdimir)).
+* Add setting `format_json_object_each_row_column_for_object_name` to write/parse object name as column value in JSONObjectEachRow format. [#41703](https://github.com/ClickHouse/ClickHouse/pull/41703) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add BLAKE3 hash-function to SQL. [#33435](https://github.com/ClickHouse/ClickHouse/pull/33435) ([BoloniniD](https://github.com/BoloniniD)).
+* The function `javaHash` has been extended to integers. [#41131](https://github.com/ClickHouse/ClickHouse/pull/41131) ([JackyWoo](https://github.com/JackyWoo)).
+* Add OpenTelemetry support to ON CLUSTER DDL (require `distributed_ddl_entry_format_version` to be set to 4). [#41484](https://github.com/ClickHouse/ClickHouse/pull/41484) ([Frank Chen](https://github.com/FrankChen021)).
+* Added system table `asynchronous_insert_log`. It contains information about asynchronous inserts (including results of queries in fire-and-forget mode (with `wait_for_async_insert=0`)) for better introspection. [#42040](https://github.com/ClickHouse/ClickHouse/pull/42040) ([Anton Popov](https://github.com/CurtizJ)).
+* Add support for methods `lz4`, `bz2`, `snappy` in HTTP's `Accept-Encoding` which is a non-standard extension to HTTP protocol. [#42071](https://github.com/ClickHouse/ClickHouse/pull/42071) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Adds Morton Coding (ZCurve) encode/decode functions. [#41753](https://github.com/ClickHouse/ClickHouse/pull/41753) ([Constantine Peresypkin](https://github.com/pkit)).
+* Add support for `SET setting_name = DEFAULT`. [#42187](https://github.com/ClickHouse/ClickHouse/pull/42187) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
+
+#### Experimental Feature
+* Added new infrastructure for query analysis and planning under the `allow_experimental_analyzer` setting. [#31796](https://github.com/ClickHouse/ClickHouse/pull/31796) ([Maksim Kita](https://github.com/kitaisreal)).
+* Initial implementation of Kusto Query Language. Please don't use it. [#37961](https://github.com/ClickHouse/ClickHouse/pull/37961) ([Yong Wang](https://github.com/kashwy)).
+
+#### Performance Improvement
+* Relax the "Too many parts" threshold. This closes [#6551](https://github.com/ClickHouse/ClickHouse/issues/6551). Now ClickHouse will allow more parts in a partition if the average part size is large enough (at least 10 GiB). This allows to have up to petabytes of data in a single partition of a single table on a single server, which is possible using disk shelves or object storage. [#42002](https://github.com/ClickHouse/ClickHouse/pull/42002) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Implement operator precedence element parser to make the required stack size smaller. [#34892](https://github.com/ClickHouse/ClickHouse/pull/34892) ([Nikolay Degterinsky](https://github.com/evillique)).
+* DISTINCT in order optimization leverage sorting properties of data streams. This improvement will enable reading in order for DISTINCT if applicable (before it was necessary to provide ORDER BY for columns in DISTINCT). [#41014](https://github.com/ClickHouse/ClickHouse/pull/41014) ([Igor Nikonov](https://github.com/devcrafter)).
+* ColumnVector: optimize UInt8 index with AVX512VBMI. [#41247](https://github.com/ClickHouse/ClickHouse/pull/41247) ([Guo Wangyang](https://github.com/guowangy)).
+* Optimize the lock contentions for `ThreadGroupStatus::mutex`. The performance experiments of **SSB** (Star Schema Benchmark) on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) shows that this change could bring a **2.95x** improvement of the geomean of all subcases' QPS. [#41675](https://github.com/ClickHouse/ClickHouse/pull/41675) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Add `ldapr` capabilities to AArch64 builds. This is supported from Graviton 2+, Azure and GCP instances. Only appeared in clang-15 [not so long ago](https://github.com/llvm/llvm-project/commit/9609b5daffe9fd28d83d83da895abc5113f76c24). [#41778](https://github.com/ClickHouse/ClickHouse/pull/41778) ([Daniel Kutenin](https://github.com/danlark1)).
+* Improve performance when comparing strings and one argument is an empty constant string. [#41870](https://github.com/ClickHouse/ClickHouse/pull/41870) ([Jiebin Sun](https://github.com/jiebinn)).
+* Optimize `insertFrom` of ColumnAggregateFunction to share Aggregate State in some cases. [#41960](https://github.com/ClickHouse/ClickHouse/pull/41960) ([flynn](https://github.com/ucasfl)).
+* Make writing to `azure_blob_storage` disks faster (respect `max_single_part_upload_size` instead of writing a block per each buffer size). Inefficiency mentioned in [#41754](https://github.com/ClickHouse/ClickHouse/issues/41754). [#42041](https://github.com/ClickHouse/ClickHouse/pull/42041) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Make thread ids in the process list and query_log unique to avoid waste. [#42180](https://github.com/ClickHouse/ClickHouse/pull/42180) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Support skipping cache completely (both download to cache and reading cached data) in case the requested read range exceeds the threshold defined by cache setting `bypass_cache_threashold`, requires to be enabled with `enable_bypass_cache_with_threshold`). [#42418](https://github.com/ClickHouse/ClickHouse/pull/42418) ([Han Shukai](https://github.com/KinderRiven)). This helps on slow local disks.
+
+#### Improvement
+* Add setting `allow_implicit_no_password`: in combination with `allow_no_password` it forbids creating a user with no password unless `IDENTIFIED WITH no_password` is explicitly specified. [#41341](https://github.com/ClickHouse/ClickHouse/pull/41341) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Embedded Keeper will always start in the background allowing ClickHouse to start without achieving quorum. [#40991](https://github.com/ClickHouse/ClickHouse/pull/40991) ([Antonio Andelic](https://github.com/antonio2368)).
+* Made reestablishing a new connection to ZooKeeper more reactive in case of expiration of the previous one. Previously there was a task which spawns every minute by default and thus a table could be in readonly state for about this time. [#41092](https://github.com/ClickHouse/ClickHouse/pull/41092) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Now projections can be used with zero copy replication (zero-copy replication is a non-production feature). [#41147](https://github.com/ClickHouse/ClickHouse/pull/41147) ([alesapin](https://github.com/alesapin)).
+* Support expression `(EXPLAIN SELECT ...)` in a subquery. Queries like `SELECT * FROM (EXPLAIN PIPELINE SELECT col FROM TABLE ORDER BY col)` became valid. [#40630](https://github.com/ClickHouse/ClickHouse/pull/40630) ([Vladimir C](https://github.com/vdimir)).
+* Allow changing `async_insert_max_data_size` or `async_insert_busy_timeout_ms` in scope of query. E.g. user wants to insert data rarely and she doesn't have access to the server config to tune default settings. [#40668](https://github.com/ClickHouse/ClickHouse/pull/40668) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Improvements for reading from remote filesystems, made threadpool size for reads/writes configurable. Closes [#41070](https://github.com/ClickHouse/ClickHouse/issues/41070). [#41011](https://github.com/ClickHouse/ClickHouse/pull/41011) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Support all combinators combination in WindowTransform/arratReduce*/initializeAggregation/aggregate functions versioning. Previously combinators like `ForEach/Resample/Map` didn't work in these places, using them led to exception like`State function ... inserts results into non-state column`. [#41107](https://github.com/ClickHouse/ClickHouse/pull/41107) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add function `tryDecrypt` that returns NULL when decrypt fails (e.g. decrypt with incorrect key) instead of throwing an exception. [#41206](https://github.com/ClickHouse/ClickHouse/pull/41206) ([Duc Canh Le](https://github.com/canhld94)).
+* Add the `unreserved_space` column to the `system.disks` table to check how much space is not taken by reservations per disk. [#41254](https://github.com/ClickHouse/ClickHouse/pull/41254) ([filimonov](https://github.com/filimonov)).
+* Support s3 authorization headers in table function arguments. [#41261](https://github.com/ClickHouse/ClickHouse/pull/41261) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add support for MultiRead in Keeper and internal ZooKeeper client (this is an extension to ZooKeeper protocol, only available in ClickHouse Keeper). [#41410](https://github.com/ClickHouse/ClickHouse/pull/41410) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add support for decimal type comparing with floating point literal in IN operator. [#41544](https://github.com/ClickHouse/ClickHouse/pull/41544) ([liang.huang](https://github.com/lhuang09287750)).
+* Allow readable size values (like `1TB`) in cache config. [#41688](https://github.com/ClickHouse/ClickHouse/pull/41688) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* ClickHouse could cache stale DNS entries for some period of time (15 seconds by default) until the cache won't be updated asynchronously. During these periods ClickHouse can nevertheless try to establish a connection and produce errors. This behavior is fixed. [#41707](https://github.com/ClickHouse/ClickHouse/pull/41707) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add interactive history search with fzf-like utility (fzf/sk) for `clickhouse-client`/`clickhouse-local` (note you can use `FZF_DEFAULT_OPTS`/`SKIM_DEFAULT_OPTIONS` to additionally configure the behavior). [#41730](https://github.com/ClickHouse/ClickHouse/pull/41730) ([Azat Khuzhin](https://github.com/azat)).
+* Only allow clients connecting to a secure server with an invalid certificate only to proceed with the '--accept-certificate' flag. [#41743](https://github.com/ClickHouse/ClickHouse/pull/41743) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Add function `tryBase58Decode`, similar to the existing function `tryBase64Decode`. [#41824](https://github.com/ClickHouse/ClickHouse/pull/41824) ([Robert Schulze](https://github.com/rschu1ze)).
+* Improve feedback when replacing partition with different primary key. Fixes [#34798](https://github.com/ClickHouse/ClickHouse/issues/34798). [#41838](https://github.com/ClickHouse/ClickHouse/pull/41838) ([Salvatore](https://github.com/tbsal)).
+* Fix parallel parsing: segmentator now checks `max_block_size`. This fixed memory overallocation in case of parallel parsing and small LIMIT. [#41852](https://github.com/ClickHouse/ClickHouse/pull/41852) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Don't add "TABLE_IS_DROPPED" exception to `system.errors` if it's happened during SELECT from a system table and was ignored. [#41908](https://github.com/ClickHouse/ClickHouse/pull/41908) ([AlfVII](https://github.com/AlfVII)).
+* Improve option `enable_extended_results_for_datetime_functions` to return results of type DateTime64 for functions `toStartOfDay`, `toStartOfHour`, `toStartOfFifteenMinutes`, `toStartOfTenMinutes`, `toStartOfFiveMinutes`, `toStartOfMinute` and `timeSlot`. [#41910](https://github.com/ClickHouse/ClickHouse/pull/41910) ([Roman Vasin](https://github.com/rvasin)).
+* Improve `DateTime` type inference for text formats. Now it respects setting `date_time_input_format` and doesn't try to infer datetimes from numbers as timestamps. Closes [#41389](https://github.com/ClickHouse/ClickHouse/issues/41389) Closes [#42206](https://github.com/ClickHouse/ClickHouse/issues/42206). [#41912](https://github.com/ClickHouse/ClickHouse/pull/41912) ([Kruglov Pavel](https://github.com/Avogar)).
+* Remove confusing warning when inserting with `perform_ttl_move_on_insert` = false. [#41980](https://github.com/ClickHouse/ClickHouse/pull/41980) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Allow user to write `countState(*)` similar to `count(*)`. This closes [#9338](https://github.com/ClickHouse/ClickHouse/issues/9338). [#41983](https://github.com/ClickHouse/ClickHouse/pull/41983) ([Amos Bird](https://github.com/amosbird)).
+* Fix `rankCorr` size overflow. [#42020](https://github.com/ClickHouse/ClickHouse/pull/42020) ([Duc Canh Le](https://github.com/canhld94)).
+* Added an option to specify an arbitrary string as an environment name in the Sentry's config for more handy reports. [#42037](https://github.com/ClickHouse/ClickHouse/pull/42037) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Fix parsing out-of-range Date from CSV. [#42044](https://github.com/ClickHouse/ClickHouse/pull/42044) ([Andrey Zvonov](https://github.com/zvonand)).
+* `parseDataTimeBestEffort` now supports comma between date and time. Closes [#42038](https://github.com/ClickHouse/ClickHouse/issues/42038). [#42049](https://github.com/ClickHouse/ClickHouse/pull/42049) ([flynn](https://github.com/ucasfl)).
+* Improved stale replica recovery process for `ReplicatedMergeTree`. If a lost replica has some parts which are absent from a healthy replica, but these parts should appear in the future according to the replication queue of the healthy replica, then the lost replica will keep such parts instead of detaching them. [#42134](https://github.com/ClickHouse/ClickHouse/pull/42134) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Add a possibility to use `Date32` arguments for date_diff function. Fix issue in date_diff function when using DateTime64 arguments with a start date before Unix epoch and end date after Unix epoch. [#42308](https://github.com/ClickHouse/ClickHouse/pull/42308) ([Roman Vasin](https://github.com/rvasin)).
+* When uploading big parts to Minio, 'Complete Multipart Upload' can take a long time. Minio sends heartbeats every 10 seconds (see https://github.com/minio/minio/pull/7198). But clickhouse times out earlier, because the default send/receive timeout is [set](https://github.com/ClickHouse/ClickHouse/blob/cc24fcd6d5dfb67f5f66f5483e986bd1010ad9cf/src/IO/S3/PocoHTTPClient.cpp#L123) to 5 seconds. [#42321](https://github.com/ClickHouse/ClickHouse/pull/42321) ([filimonov](https://github.com/filimonov)).
+* Fix rarely invalid cast of aggregate state types with complex types such as Decimal. This fixes [#42408](https://github.com/ClickHouse/ClickHouse/issues/42408). [#42417](https://github.com/ClickHouse/ClickHouse/pull/42417) ([Amos Bird](https://github.com/amosbird)).
+* Allow to use `Date32` arguments for `dateName` function. [#42554](https://github.com/ClickHouse/ClickHouse/pull/42554) ([Roman Vasin](https://github.com/rvasin)).
+* Now filters with NULL literals will be used during index analysis. [#34063](https://github.com/ClickHouse/ClickHouse/issues/34063). [#41842](https://github.com/ClickHouse/ClickHouse/pull/41842) ([Amos Bird](https://github.com/amosbird)).
+* Merge parts if every part in the range is older than a certain threshold. The threshold can be set by using `min_age_to_force_merge_seconds`. This closes [#35836](https://github.com/ClickHouse/ClickHouse/issues/35836). [#42423](https://github.com/ClickHouse/ClickHouse/pull/42423) ([Antonio Andelic](https://github.com/antonio2368)). This is continuation of [#39550i](https://github.com/ClickHouse/ClickHouse/pull/39550) by [@fastio](https://github.com/fastio) who implemented most of the logic.
+* Improve the time to recover lost keeper connections. [#42541](https://github.com/ClickHouse/ClickHouse/pull/42541) ([Raúl Marín](https://github.com/Algunenano)).
+
+#### Build/Testing/Packaging Improvement
+* Add fuzzer for table definitions [#40096](https://github.com/ClickHouse/ClickHouse/pull/40096) ([Anton Popov](https://github.com/CurtizJ)). This represents the biggest advancement for ClickHouse testing in this year so far.
+* Beta version of the ClickHouse Cloud service is released: [https://clickhouse.cloud/](https://clickhouse.cloud/). It provides the easiest way to use ClickHouse (even slightly easier than the single-command installation).
+* Added support of WHERE clause generation to AST Fuzzer and possibility to add or remove ORDER BY and WHERE clause. [#38519](https://github.com/ClickHouse/ClickHouse/pull/38519) ([Ilya Yatsishin](https://github.com/qoega)).
+* Aarch64 binaries now require at least ARMv8.2, released in 2016. Most notably, this enables use of ARM LSE, i.e. native atomic operations. Also, CMake build option "NO_ARMV81_OR_HIGHER" has been added to allow compilation of binaries for older ARMv8.0 hardware, e.g. Raspberry Pi 4. [#41610](https://github.com/ClickHouse/ClickHouse/pull/41610) ([Robert Schulze](https://github.com/rschu1ze)).
+* Allow building ClickHouse with Musl (small changes after it was already supported but broken). [#41987](https://github.com/ClickHouse/ClickHouse/pull/41987) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

 #### Backward Incompatible Change
+
 * Extended range of `Date32` and `DateTime64` to support dates from the year 1900 to 2299. In previous versions, the supported interval was only from the year 1925 to 2283. The implementation is using the proleptic Gregorian calendar (which is conformant with [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601):2004 (clause 3.2.1 The Gregorian calendar)) instead of accounting for historical transitions from the Julian to the Gregorian calendar. This change affects implementation-specific behavior for out-of-range arguments. E.g. if in previous versions the value of `1899-01-01` was clamped to `1925-01-01`, in the new version it will be clamped to `1900-01-01`. It changes the behavior of rounding with `toStartOfInterval` if you pass `INTERVAL 3 QUARTER` up to one quarter because the intervals are counted from an implementation-specific point of time. Closes [#28216](https://github.com/ClickHouse/ClickHouse/issues/28216), improves [#38393](https://github.com/ClickHouse/ClickHouse/issues/38393).

 * Make the remote filesystem cache composable, allow not to evict certain files (regarding idx, mrk, ..), delete old cache version. Now it is possible to configure cache over Azure blob storage disk, over Local disk, over StaticWeb disk, etc. This PR is marked backward incompatible because cache configuration changes and in order for cache to work need to update the config file. Old cache will still be used with new configuration. The server will startup fine with the old cache configuration. Closes https://github.com/ClickHouse/ClickHouse/issues/36140.

 * Intel® In-Memory Analytics Accelerator (Intel® IAA) is a hardware accelerator available in the upcoming generation of Intel® Xeon® Scalable processors ("Sapphire Rapids"). Its goal is to speed up common operations in analytics like data (de)compression and filtering. ClickHouse gained the new "DeflateQpl" compression codec which utilizes the Intel® IAA offloading technology to provide a high-performance DEFLATE implementation. The codec uses the [Intel® Query Processing Library (QPL)](https://github.com/intel/qpl) which abstracts access to the hardware accelerator, respectively to a software fallback in case the hardware accelerator is not available. DEFLATE provides in general higher compression rates than ClickHouse's LZ4 default codec, and as a result, offers less disk I/O and lower main memory consumption.

[#38719](https://github.com/ClickHouse/ClickHouse/pull/38719) ([Igor Nikonov](https://github.com/devcrafter)). Improve memory usage (significantly) and query execution time + use `DistinctSortedChunkTransform` for final distinct when `DISTINCT` columns match `ORDER BY` columns, but rename to `DistinctSortedStreamTransform` in `EXPLAIN PIPELINE` → this improves memory usage significantly + remove unnecessary allocations in hot loop in `DistinctSortedChunkTransform`. [#39432](https://github.com/ClickHouse/ClickHouse/pull/39432) ([Igor Nikonov](https://github.com/devcrafter)). Use `DistinctSortedTransform` only when sort description is applicable to DISTINCT columns, otherwise fall back to ordinary DISTINCT implementation + it allows making less checks during `DistinctSortedTransform` execution. [#39528](https://github.com/ClickHouse/ClickHouse/pull/39528) ([Igor Nikonov](https://github.com/devcrafter)). Fix: `DistinctSortedTransform` didn't take advantage of sorting.

 #### Improvement
+
 * Normalize `AggregateFunction` types and state representations because optimizations like [#35788](https://github.com/ClickHouse/ClickHouse/pull/35788) will treat `count(not null columns)` as `count()`, which might confuses distributed interpreters with the following error : `Conversion from AggregateFunction(count) to AggregateFunction(count, Int64) is not supported`.

 * Rework and simplify the `system.backups` table, remove the `internal` column, allow user to set the ID of operation, add columns `num_files`, `uncompressed_size`, `compressed_size`, `start_time`, `end_time`. [#39503](https://github.com/ClickHouse/ClickHouse/pull/39503) ([Vitaly Baranov](https://github.com/vitlibar)).
 * Improved structure of DDL query result table for `Replicated` database (separate columns with shard and replica name, more clear status) - `CREATE TABLE ... ON CLUSTER` queries can be normalized on initiator first if `distributed_ddl_entry_format_version` is set to 3 (default value). It means that `ON CLUSTER` queries may not work if initiator does not belong to the cluster that specified in query.

 ### <a id="227"></a> ClickHouse release 22.7, 2022-07-21
 
 #### Upgrade Notes
+
 * Enable setting `enable_positional_arguments` by default. It allows queries like `SELECT ... ORDER BY 1, 2` where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. [#38204](https://github.com/ClickHouse/ClickHouse/pull/38204) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
 * Disable `format_csv_allow_single_quotes` by default. See [#37096](https://github.com/ClickHouse/ClickHouse/issues/37096). ([Kruglov Pavel](https://github.com/Avogar)).
 * `Ordinary` database engine and old storage definition syntax for `*MergeTree` tables are deprecated. By default it's not possible to create new databases with `Ordinary` engine. If `system` database has `Ordinary` engine it will be automatically converted to `Atomic` on server startup. There are settings to keep old behavior (`allow_deprecated_database_ordinary` and `allow_deprecated_syntax_for_merge_tree`), but these settings may be removed in future releases. [#38335](https://github.com/ClickHouse/ClickHouse/pull/38335) ([Alexander Tokmakov](https://github.com/tavplubix)).
 * Force rewriting comma join to inner by default (set default value `cross_to_inner_join_rewrite = 2`). To have old behavior set `cross_to_inner_join_rewrite = 1`. [#39326](https://github.com/ClickHouse/ClickHouse/pull/39326) ([Vladimir C](https://github.com/vdimir)). If you will face any incompatibilities, you can turn this setting back.

 #### Experimental Feature
 
 * Parallel reading from multiple replicas within a shard during distributed query without using sample key. To enable this, set `allow_experimental_parallel_reading_from_replicas = 1` and `max_parallel_replicas` to any number. This closes [#26748](https://github.com/ClickHouse/ClickHouse/issues/26748).

+### ClickHouse release v22.10.1.1877-stable (98ab5a3c189) FIXME as compared to v22.9.1.2603-stable (3030d4c7ff0)
+
+#### Backward Incompatible Change
+* Rename cache commands: `show caches` -> `show filesystem caches`, `describe cache` -> `describe filesystem cache`. [#41508](https://github.com/ClickHouse/ClickHouse/pull/41508) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Remove support for the `WITH TIMEOUT` section for `LIVE VIEW`. This closes [#40557](https://github.com/ClickHouse/ClickHouse/issues/40557). [#42173](https://github.com/ClickHouse/ClickHouse/pull/42173) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Add Rust code support into ClickHouse with BLAKE3 hash-function library as an example. [#33435](https://github.com/ClickHouse/ClickHouse/pull/33435) ([BoloniniD](https://github.com/BoloniniD)).
+* This is the initial implement of Kusto Query Language. (MVP). [#37961](https://github.com/ClickHouse/ClickHouse/pull/37961) ([Yong Wang](https://github.com/kashwy)).
+* * Support limiting of temporary data stored on disk using settings `max_temporary_data_on_disk_size_for_user`/`max_temporary_data_on_disk_size_for_query` . [#40893](https://github.com/ClickHouse/ClickHouse/pull/40893) ([Vladimir C](https://github.com/vdimir)).
+* Support Java integers hashing in `javaHash`. [#41131](https://github.com/ClickHouse/ClickHouse/pull/41131) ([JackyWoo](https://github.com/JackyWoo)).
+* This PR is to support the OpenSSL in-house build like the BoringSSL submodule. Build flag i.e. ENABLE_CH_BUNDLE_BORINGSSL is used to choose between BoringSSL and OpenSSL. By default, the BoringSSL in-house build will be used. [#41142](https://github.com/ClickHouse/ClickHouse/pull/41142) ([MeenaRenganathan22](https://github.com/MeenaRenganathan22)).
+* Composable protocol configuration is added. [#41198](https://github.com/ClickHouse/ClickHouse/pull/41198) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Add OpenTelemetry support to ON CLUSTER DDL(require `distributed_ddl_entry_format_version` to be set to 4). [#41484](https://github.com/ClickHouse/ClickHouse/pull/41484) ([Frank Chen](https://github.com/FrankChen021)).
+* Add setting `format_json_object_each_row_column_for_object_name` to write/parse object name as column value in JSONObjectEachRow format. [#41703](https://github.com/ClickHouse/ClickHouse/pull/41703) ([Kruglov Pavel](https://github.com/Avogar)).
+* adds Morton Coding (ZCurve) encode/decode functions. [#41753](https://github.com/ClickHouse/ClickHouse/pull/41753) ([Constantine Peresypkin](https://github.com/pkit)).
+* Implement support for different UUID binary formats with support for the two most prevalent ones: the default big-endian and Microsoft's mixed-endian as specified in [RFC 4122](https://datatracker.ietf.org/doc/html/rfc4122#section-4.1.1). [#42108](https://github.com/ClickHouse/ClickHouse/pull/42108) ([ltrk2](https://github.com/ltrk2)).
+* Added an aggregate function `analysisOfVariance` (`anova`) to perform a statistical test over several groups of normally distributed observations to find out whether all groups have the same mean or not. Original PR [#37872](https://github.com/ClickHouse/ClickHouse/issues/37872). [#42131](https://github.com/ClickHouse/ClickHouse/pull/42131) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add support for `SET setting_name = DEFAULT`. [#42187](https://github.com/ClickHouse/ClickHouse/pull/42187) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
+* * Add `URL` Functions which conform rfc. Functions include: `cutToFirstSignificantSubdomainCustomRFC`, `cutToFirstSignificantSubdomainCustomWithWWWRFC`, `cutToFirstSignificantSubdomainRFC`, `cutToFirstSignificantSubdomainWithWWWRFC`, `domainRFC`, `domainWithoutWWWRFC`, `firstSignificantSubdomainCustomRFC`, `firstSignificantSubdomainRFC`, `portRFC`, `topLevelDomainRFC`. [#42274](https://github.com/ClickHouse/ClickHouse/pull/42274) ([Quanfa Fu](https://github.com/dentiscalprum)).
+* Added functions (`randUniform`, `randNormal`, `randLogNormal`, `randExponential`, `randChiSquared`, `randStudentT`, `randFisherF`, `randBernoulli`, `randBinomial`, `randNegativeBinomial`, `randPoisson` ) to generate random values according to the specified distributions. This closes [#21834](https://github.com/ClickHouse/ClickHouse/issues/21834). [#42411](https://github.com/ClickHouse/ClickHouse/pull/42411) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+
+#### Performance Improvement
+* Implement operator precedence element parser to resolve stack overflow issues and make the required stack size smaller. [#34892](https://github.com/ClickHouse/ClickHouse/pull/34892) ([Nikolay Degterinsky](https://github.com/evillique)).
+* DISTINCT in order optimization leverage sorting properties of data streams. This improvement will enable reading in order for DISTINCT if applicable (before it was necessary to provide ORDER BY for columns in DISTINCT). [#41014](https://github.com/ClickHouse/ClickHouse/pull/41014) ([Igor Nikonov](https://github.com/devcrafter)).
+* ColumnVector: optimize UInt8 index with AVX512VBMI. [#41247](https://github.com/ClickHouse/ClickHouse/pull/41247) ([Guo Wangyang](https://github.com/guowangy)).
+* The performance experiments of **SSB** (Star Schema Benchmark) on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) shows that this change could bring a **2.95x** improvement of the geomean of all subcases' QPS. [#41675](https://github.com/ClickHouse/ClickHouse/pull/41675) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Fixed slowness in JSONExtract with LowCardinality(String) tuples. [#41726](https://github.com/ClickHouse/ClickHouse/pull/41726) ([AlfVII](https://github.com/AlfVII)).
+* Add ldapr capabilities to AArch64 builds. This is supported from Graviton 2+, Azure and GCP instances. Only appeared in clang-15 [not so long ago](https://github.com/llvm/llvm-project/commit/9609b5daffe9fd28d83d83da895abc5113f76c24). [#41778](https://github.com/ClickHouse/ClickHouse/pull/41778) ([Daniel Kutenin](https://github.com/danlark1)).
+* Improve performance when comparing strings and one argument is empty constant string. [#41870](https://github.com/ClickHouse/ClickHouse/pull/41870) ([Jiebin Sun](https://github.com/jiebinn)).
+* optimize insertFrom of ColumnAggregateFunction to share Aggregate State in some cases. [#41960](https://github.com/ClickHouse/ClickHouse/pull/41960) ([flynn](https://github.com/ucasfl)).
+* Relax the "Too many parts" threshold. This closes [#6551](https://github.com/ClickHouse/ClickHouse/issues/6551). Now ClickHouse will allow more parts in a partition if the average part size is large enough (at least 10 GiB). This allows to have up to petabytes of data in a single partition of a single table on a single server, which is possible using disk shelves or object storage. [#42002](https://github.com/ClickHouse/ClickHouse/pull/42002) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Make writing to AzureBlobStorage more efficient (respect `max_single_part_upload_size` instead of writing a block per each buffer size). Inefficiency mentioned in [#41754](https://github.com/ClickHouse/ClickHouse/issues/41754). [#42041](https://github.com/ClickHouse/ClickHouse/pull/42041) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Make thread ids in the process list and query_log unique to avoid waste. [#42180](https://github.com/ClickHouse/ClickHouse/pull/42180) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### Improvement
+* Added new infrastructure for query analysis and planning under `allow_experimental_analyzer` setting. [#31796](https://github.com/ClickHouse/ClickHouse/pull/31796) ([Maksim Kita](https://github.com/kitaisreal)).
+* * Support expression `(EXPLAIN SELECT ...)` in a subquery. Queries like `SELECT * FROM (EXPLAIN PIPELINE SELECT col FROM TABLE ORDER BY col)` became valid. [#40630](https://github.com/ClickHouse/ClickHouse/pull/40630) ([Vladimir C](https://github.com/vdimir)).
+* Currently changing `async_insert_max_data_size` or `async_insert_busy_timeout_ms` in scope of query makes no sense and this leads to bad user experience. E.g. user wants to insert data rarely and he doesn't have an access to server config to tune default settings. [#40668](https://github.com/ClickHouse/ClickHouse/pull/40668) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Embedded Keeper will always start in the background allowing ClickHouse to start without achieving quorum. [#40991](https://github.com/ClickHouse/ClickHouse/pull/40991) ([Antonio Andelic](https://github.com/antonio2368)).
+* Improvements for reading from remote filesystems, made threadpool size for reads/writes configurable. Closes [#41070](https://github.com/ClickHouse/ClickHouse/issues/41070). [#41011](https://github.com/ClickHouse/ClickHouse/pull/41011) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Made reestablishing a new connection more reactive in case of expiration of the previous one. Previously there was a task which spawns every minute by default and thus a table could be in readonly state for about this time. [#41092](https://github.com/ClickHouse/ClickHouse/pull/41092) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Support all combinators combination in WindowTransform/arratReduce*/initializeAggregation/aggregate functions versioning. Previously combinators like `ForEach/Resample/Map` didn't work in these places, using them led to exception like`State function ... inserts results into non-state column`. [#41107](https://github.com/ClickHouse/ClickHouse/pull/41107) ([Kruglov Pavel](https://github.com/Avogar)).
+* Now projections can be used with zero copy replication. [#41147](https://github.com/ClickHouse/ClickHouse/pull/41147) ([alesapin](https://github.com/alesapin)).
+* - Add function tryDecrypt that returns NULL when decrypt fail (e.g. decrypt with incorrect key) instead of throwing exception. [#41206](https://github.com/ClickHouse/ClickHouse/pull/41206) ([Duc Canh Le](https://github.com/canhld94)).
+* Add the `unreserved_space` column to the `system.disks` table to check how much space is not taken by reservations per disk. [#41254](https://github.com/ClickHouse/ClickHouse/pull/41254) ([filimonov](https://github.com/filimonov)).
+* Support s3 authorisation headers from ast arguments. [#41261](https://github.com/ClickHouse/ClickHouse/pull/41261) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add setting 'allow_implicit_no_password' that forbids creating a user with no password unless 'IDENTIFIED WITH no_password' is explicitly specified. [#41341](https://github.com/ClickHouse/ClickHouse/pull/41341) ([Nikolay Degterinsky](https://github.com/evillique)).
+* keeper-improvement: add support for uploading snapshots to S3. S3 information can be defined inside `keeper_server.s3_snapshot`. [#41342](https://github.com/ClickHouse/ClickHouse/pull/41342) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add support for MultiRead in Keeper and internal ZooKeeper client. [#41410](https://github.com/ClickHouse/ClickHouse/pull/41410) ([Antonio Andelic](https://github.com/antonio2368)).
+* add a support for decimal type comparing with floating point literal in IN operator. [#41544](https://github.com/ClickHouse/ClickHouse/pull/41544) ([liang.huang](https://github.com/lhuang09287750)).
+* Allow readable size values in cache config. [#41688](https://github.com/ClickHouse/ClickHouse/pull/41688) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Check file path for path traversal attacks in errors logger for input formats. [#41694](https://github.com/ClickHouse/ClickHouse/pull/41694) ([Kruglov Pavel](https://github.com/Avogar)).
+* ClickHouse could cache stale DNS entries for some period of time (15 seconds by default) until the cache won't be updated asynchronously. During these period ClickHouse can nevertheless try to establish a connection and produce errors. This behaviour is fixed. [#41707](https://github.com/ClickHouse/ClickHouse/pull/41707) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add interactive history search with fzf-like utility (fzf/sk) for `clickhouse-client`/`clickhouse-local` (note you can use `FZF_DEFAULT_OPTS`/`SKIM_DEFAULT_OPTIONS` to additionally configure the behavior). [#41730](https://github.com/ClickHouse/ClickHouse/pull/41730) ([Azat Khuzhin](https://github.com/azat)).
+* For client when connecting to a secure server with invalid certificate only allow to proceed with '--accept-certificate' flag. [#41743](https://github.com/ClickHouse/ClickHouse/pull/41743) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Add function "tryBase58Decode()", similar to the existing function "tryBase64Decode()". [#41824](https://github.com/ClickHouse/ClickHouse/pull/41824) ([Robert Schulze](https://github.com/rschu1ze)).
+* Improve feedback when replacing partition with different primary key. Fixes [#34798](https://github.com/ClickHouse/ClickHouse/issues/34798). [#41838](https://github.com/ClickHouse/ClickHouse/pull/41838) ([Salvatore](https://github.com/tbsal)).
+* Replace back `clickhouse su` command with `sudo -u` in start in order to respect limits in `/etc/security/limits.conf`. [#41847](https://github.com/ClickHouse/ClickHouse/pull/41847) ([Eugene Konkov](https://github.com/ekonkov)).
+* Fix parallel parsing: segmentator now checks max_block_size. [#41852](https://github.com/ClickHouse/ClickHouse/pull/41852) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Don't report TABLE_IS_DROPPED exception in order to skip table in case is was just dropped. [#41908](https://github.com/ClickHouse/ClickHouse/pull/41908) ([AlfVII](https://github.com/AlfVII)).
+* Improve option enable_extended_results_for_datetime_functions to return results of type DateTime64 for functions toStartOfDay, toStartOfHour, toStartOfFifteenMinutes, toStartOfTenMinutes, toStartOfFiveMinutes, toStartOfMinute and timeSlot. [#41910](https://github.com/ClickHouse/ClickHouse/pull/41910) ([Roman Vasin](https://github.com/rvasin)).
+* Improve DateTime type inference for text formats. Now it respect setting `date_time_input_format` and doesn't try to infer datetimes from numbers as timestamps. Closes [#41389](https://github.com/ClickHouse/ClickHouse/issues/41389) Closes [#42206](https://github.com/ClickHouse/ClickHouse/issues/42206). [#41912](https://github.com/ClickHouse/ClickHouse/pull/41912) ([Kruglov Pavel](https://github.com/Avogar)).
+* Remove confusing warning when inserting with `perform_ttl_move_on_insert`=false. [#41980](https://github.com/ClickHouse/ClickHouse/pull/41980) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Allow user to write `countState(*)` similar to `count(*)`. This closes [#9338](https://github.com/ClickHouse/ClickHouse/issues/9338). [#41983](https://github.com/ClickHouse/ClickHouse/pull/41983) ([Amos Bird](https://github.com/amosbird)).
+* - Fix rankCorr size overflow. [#42020](https://github.com/ClickHouse/ClickHouse/pull/42020) ([Duc Canh Le](https://github.com/canhld94)).
+* Added an option to specify an arbitrary string as an environment name in the Sentry's config for more handy reports. [#42037](https://github.com/ClickHouse/ClickHouse/pull/42037) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Added system table `asynchronous_insert_log `. It contains information about asynchronous inserts (including results of queries in fire-and-forget mode (with `wait_for_async_insert=0`)) for better introspection. [#42040](https://github.com/ClickHouse/ClickHouse/pull/42040) ([Anton Popov](https://github.com/CurtizJ)).
+* Fix parsing out-of-range Date from CSV:. [#42044](https://github.com/ClickHouse/ClickHouse/pull/42044) ([Andrey Zvonov](https://github.com/zvonand)).

+* Add support for methods lz4, bz2, snappy in 'Accept-Encoding'. [#42071](https://github.com/ClickHouse/ClickHouse/pull/42071) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Various minor fixes for BLAKE3 function. [#42073](https://github.com/ClickHouse/ClickHouse/pull/42073) ([BoloniniD](https://github.com/BoloniniD)).
+* Improved stale replica recovery process for `ReplicatedMergeTree`. If lost replica have some parts which absent on a healthy replica, but these parts should appear in future according to replication queue of the healthy replica, then lost replica will keep such parts instead of detaching them. [#42134](https://github.com/ClickHouse/ClickHouse/pull/42134) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Support BACKUP to S3 with as-is path/data structure. [#42232](https://github.com/ClickHouse/ClickHouse/pull/42232) ([Azat Khuzhin](https://github.com/azat)).
+* Add a possibility to use Date32 arguments for date_diff function. Fix issue in date_diff function when using DateTime64 arguments with start date before Unix epoch and end date after Unix epoch. [#42308](https://github.com/ClickHouse/ClickHouse/pull/42308) ([Roman Vasin](https://github.com/rvasin)).
+* When uploading big parts to minio, 'Complete Multipart Upload' can take a long time. Minio sends heartbeats every 10 seconds (see https://github.com/minio/minio/pull/7198). But clickhouse times out earlier, because the default send/receive timeout is [set](https://github.com/ClickHouse/ClickHouse/blob/cc24fcd6d5dfb67f5f66f5483e986bd1010ad9cf/src/IO/S3/PocoHTTPClient.cpp#L123) to 5 seconds. [#42321](https://github.com/ClickHouse/ClickHouse/pull/42321) ([filimonov](https://github.com/filimonov)).
+* Add `S3` as a new type of the destination of backups. [#42333](https://github.com/ClickHouse/ClickHouse/pull/42333) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Fix rarely invalid cast of aggregate state types with complex types such as Decimal. This fixes [#42408](https://github.com/ClickHouse/ClickHouse/issues/42408). [#42417](https://github.com/ClickHouse/ClickHouse/pull/42417) ([Amos Bird](https://github.com/amosbird)).
+* Support skipping cache completely (both download to cache and reading cached data) in case the requested read range exceeds the threshold defined by cache setting `bypass_cache_threashold`, requires to be enabled with `enable_bypass_cache_with_threshold`). [#42418](https://github.com/ClickHouse/ClickHouse/pull/42418) ([Han Shukai](https://github.com/KinderRiven)).
+* Merge parts if every part in the range is older than a certain threshold. The threshold can be set by using `min_age_to_force_merge_seconds`. This closes [#35836](https://github.com/ClickHouse/ClickHouse/issues/35836). [#42423](https://github.com/ClickHouse/ClickHouse/pull/42423) ([Antonio Andelic](https://github.com/antonio2368)).

+* Remove support for the `{database}` macro from the client's prompt. It was displayed incorrectly if the database was unspecified and it was not updated on `USE` statements. This closes [#25891](https://github.com/ClickHouse/ClickHouse/issues/25891). [#42508](https://github.com/ClickHouse/ClickHouse/pull/42508) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* - Improve the time to recover lost keeper connections. [#42541](https://github.com/ClickHouse/ClickHouse/pull/42541) ([Raúl Marín](https://github.com/Algunenano)).
+* Allow to use Date32 arguments for dateName function. [#42554](https://github.com/ClickHouse/ClickHouse/pull/42554) ([Roman Vasin](https://github.com/rvasin)).
+
+#### Bug Fix
+* Now filters with NULL literals will be used during index analysis. This closes https://github.com/ClickHouse/ClickHouse/pull/41814 [#34063](https://github.com/ClickHouse/ClickHouse/issues/34063). [#41842](https://github.com/ClickHouse/ClickHouse/pull/41842) ([Amos Bird](https://github.com/amosbird)).
+* - Choose correct aggregation method for LowCardinality with BigInt. [#42342](https://github.com/ClickHouse/ClickHouse/pull/42342) ([Duc Canh Le](https://github.com/canhld94)).
+* Fix using subqueries in row policy filters. This PR fixes [#32463](https://github.com/ClickHouse/ClickHouse/issues/32463). [#42562](https://github.com/ClickHouse/ClickHouse/pull/42562) ([Vitaly Baranov](https://github.com/vitlibar)).
+
+#### Build/Testing/Packaging Improvement
+* Added support of WHERE clause generation to AST Fuzzer and possibility to add or remove ORDER BY and WHERE clause. [#38519](https://github.com/ClickHouse/ClickHouse/pull/38519) ([Ilya Yatsishin](https://github.com/qoega)).
+* Aarch64 binaries now require at least ARMv8.2, released in 2016. Most notably, this enables use of ARM LSE, i.e. native atomic operations. Also, CMake build option "NO_ARMV81_OR_HIGHER" has been added to allow compilation of binaries for older ARMv8.0 hardware, e.g. Raspberry Pi 4. [#41610](https://github.com/ClickHouse/ClickHouse/pull/41610) ([Robert Schulze](https://github.com/rschu1ze)).
+* After updating runners to 22.04 cgroups stopped to work in privileged mode, here's the issue https://github.com/moby/moby/issues/42275#issuecomment-1115055846. [#41857](https://github.com/ClickHouse/ClickHouse/pull/41857) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Allow building ClickHouse with Musl (small changes after it was already supported but broken). [#41987](https://github.com/ClickHouse/ClickHouse/pull/41987) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* - Add the `$CLICKHOUSE_CRONFILE` file checking to avoid running the `sed` command to get the file not found error. [#42081](https://github.com/ClickHouse/ClickHouse/pull/42081) ([Chun-Sheng, Li](https://github.com/peter279k)).
+* Update cctz to the latest master, update tzdb to 2020e. [#42273](https://github.com/ClickHouse/ClickHouse/pull/42273) ([Dom Del Nano](https://github.com/ddelnano)).

+* 22.9 might fail to startup `ReplicatedMergeTree` table if that table was created by 20.3 or older version and was never altered, it's fixed. Fixes [#41742](https://github.com/ClickHouse/ClickHouse/issues/41742). [#41796](https://github.com/ClickHouse/ClickHouse/pull/41796) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* When the batch sending fails for some reason, it cannot be automatically recovered, and if it is not processed in time, it will lead to accumulation, and the printed error message will become longer and longer, which will cause the http thread to block. [#41813](https://github.com/ClickHouse/ClickHouse/pull/41813) ([zhongyuankai](https://github.com/zhongyuankai)).
+* Fix compact parts with compressed marks setting. Fixes [#41783](https://github.com/ClickHouse/ClickHouse/issues/41783) and [#41746](https://github.com/ClickHouse/ClickHouse/issues/41746). [#41823](https://github.com/ClickHouse/ClickHouse/pull/41823) ([alesapin](https://github.com/alesapin)).
+* Old versions of Replicated database doesn't have a special marker in [Zoo]Keeper. We need to check only whether the node contains come obscure data instead of special mark. [#41875](https://github.com/ClickHouse/ClickHouse/pull/41875) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Fix possible exception in fs cache. [#41884](https://github.com/ClickHouse/ClickHouse/pull/41884) ([Kseniia Sumarokova](https://github.com/kssenii)).

[#42084](https://github.com/ClickHouse/ClickHouse/pull/42084) ([Roman Vasin](https://github.com/rvasin)).
+* The maximum size of fetches for each table accidentally was set to 8 while the pool size could be bigger. Now the maximum size of fetches for table is equal to the pool size. [#42090](https://github.com/ClickHouse/ClickHouse/pull/42090) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* A table might be shut down and a dictionary might be detached before checking if can be dropped without breaking dependencies between table, it's fixed. Fixes [#41982](https://github.com/ClickHouse/ClickHouse/issues/41982). [#42106](https://github.com/ClickHouse/ClickHouse/pull/42106) ([Alexander Tokmakov](https://github.com/tavplubix)).

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

+## Background
 
 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.

+
+To write backups to an S3 bucket you need three pieces of information:
+- S3 endpoint,
+  for example `https://mars-doc-test.s3.amazonaws.com/backup-S3/`
+- Access key ID,
+  for example `ABC123`
+- Secret access key,
+  for example `Abc+123`
+
+:::note
+Creating an S3 bucket is covered in [Use S3 Object Storage as a ClickHouse disk](/docs/en/integrations/data-ingestion/s3/configuring-s3-for-clickhouse-use.md), just come back to this doc after saving the policy, there is no need to configure ClickHouse to use the S3 bucket.
+:::
+
+The destination for a backup will be specified like this:
+```
+S3('<S3 endpoint>/<directory>', '<Access key ID>', '<Secret access key>)
+```
+
+```sql
+CREATE TABLE data
+(
+    `key` Int,
+    `value` String,
+    `array` Array(String)
+)
+ENGINE = MergeTree
+ORDER BY tuple()
+```
+
+```sql
+INSERT INTO data SELECT *
+FROM generateRandom('key Int, value String, array Array(String)')
+LIMIT 1000
+```
+
+### Create a base (initial) backup
+
+Incremental backups require a _base_ backup to start from, this example will be used
+later as the base backup.  The first parameter of the S3 destination is the S3 endpoint followed by the directory within the bucket to use for this backup.  In this example the directory is named `my_backup`.
+
+```sql
+BACKUP TABLE data TO S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_backup', 'ABC123', 'Abc+123')
+```
+
+```response

+└──────────────────────────────────────┴────────────────┘
+```
+
+### Add more data
+
+Incremental backups are populated with the difference between the base backup and the current content of the table being backed up.  Add more data before taking the incremental backup:
+
+```sql
+INSERT INTO data SELECT *
+FROM generateRandom('key Int, value String, array Array(String)')
+LIMIT 100
+```
+### Take an incremental backup
+
+This backup command is similar to the base backup, but adds `SETTINGS base_backup` and the location of the base backup.  Note that the destination for the incremental backup is not the same directory as the base, it is the same endpoint with a different target directory within the bucket.  The base backup is in `my_backup`, and the incremental will be written to `my_incremental`:
+```sql
+BACKUP TABLE data TO S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_incremental', 'ABC123', 'Abc+123') SETTINGS base_backup = S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_backup', 'ABC123', 'Abc+123')

+└──────────────────────────────────────┴────────────────┘
+```
+### Restore from the incremental backup
+
+This command restores the incremental backup into a new table, `data3`.  Note that when an incremental backup is restored, the base backup is also included.  Specify only the incremental backup when restoring:
+```sql
+RESTORE TABLE data AS data3 FROM S3('https://mars-doc-test.s3.amazonaws.com/backup-S3/my_incremental', 'ABC123', 'Abc+123')

+

+└──────────────────────────────────────┴──────────┘
+```
+
+### Verify the count
+
+There were two inserts into the original table `data`, one with 1,000 rows and one with 100 rows, for a total of 1,100. Verify that the restored table has 1,100 rows:
+```sql
+SELECT count()
+FROM data3
+```
+```response
+┌─count()─┐
+│    1100 │
+└─────────┘
+```
+
+### Verify the content
+This compares the content of the original table, `data` with the restored table `data3`:
+```sql
+SELECT throwIf((
+        SELECT groupArray(tuple(*))
+        FROM data
+    ) != (
+        SELECT groupArray(tuple(*))
+        FROM data3
+    ), 'Data does not match after BACKUP/RESTORE')
+```
+## BACKUP/RESTORE Using an S3 Disk
+
+It is also possible to `BACKUP`/`RESTORE` to S3 by configuring an S3 disk in the ClickHouse storage configuration.  Configure the disk like this by adding a file to `/etc/clickhouse-server/config.d`:
+
+```xml

+        <disks>
+            <s3_plain>

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

+
+    <backups>
+        <allowed_disk>s3_plain</allowed_disk>
+    </backups>
+</clickhouse>
+```
+
+And then `BACKUP`/`RESTORE` as usual:
+
+```sql
+BACKUP TABLE data TO Disk('s3_plain', 'cloud_backup');
+RESTORE TABLE data AS data_restored FROM Disk('s3_plain', 'cloud_backup');
+```
+
+:::note
+But keep in mind that:
+- This disk should not be used for `MergeTree` itself, only for `BACKUP`/`RESTORE`
+- It has excessive API calls
+:::
+

 При использовании обычного IN-а, запрос отправляется на удалённые серверы, и на каждом из них выполняются подзапросы в секциях `IN` / `JOIN`.
 
 При использовании `GLOBAL IN` / `GLOBAL JOIN-а`, сначала выполняются все подзапросы для `GLOBAL IN` / `GLOBAL JOIN-ов`, и результаты складываются во временные таблицы. Затем эти временные таблицы передаются на каждый удалённый сервер, и на них выполняются запросы, с использованием этих переданных временных данных.

+该数据集由纽约公共图书馆创建。其中含有有关酒店、餐馆和咖啡馆的菜单上的菜肴及其价格的历史数据。
 
-<Content />
+来源：http://menus.nypl.org/data 
+数据为开放数据。
+
+数据来自于图书馆中的档案，因此可能不完整，以至于难以进行统计分析。尽管如此，该数据集也是非常有意思的。数据集中只有 130 万条关于菜单中的菜肴的记录 - 这对于 ClickHouse 来说是一个非常小的数据量，但这仍是一个很好的例子。

+数据集由四个表组成： 
+
+- `Menu` - 有关菜单的信息，其中包含：餐厅名称，看到菜单的日期等 
+- `Dish` - 有关菜肴的信息，其中包含：菜肴名称以及一些特征。 
+- `MenuPage` - 有关菜单中页面的信息，每个页面都属于某个 `Menu`。 
+- `MenuItem` - 菜单项。某个菜单页面上的菜肴及其价格：指向 `Dish` 和 `MenuPage`的链接。
+
+## 创建表 {#create-tables}
+
+使用 [Decimal](/docs/zh/sql-reference/data-types/decimal.md) 数据类型来存储价格。
+
+```sql
+CREATE TABLE dish
+(
+    id UInt32,
+    name String,
+    description String,
+    menus_appeared UInt32,
+    times_appeared Int32,
+    first_appeared UInt16,
+    last_appeared UInt16,
+    lowest_price Decimal64(3),
+    highest_price Decimal64(3)
+) ENGINE = MergeTree ORDER BY id;
+
+CREATE TABLE menu
+(
+    id UInt32,
+    name String,
+    sponsor String,
+    event String,
+    venue String,
+    place String,
+    physical_description String,
+    occasion String,
+    notes String,
+    call_number String,
+    keywords String,
+    language String,
+    date String,
+    location String,
+    location_type String,
+    currency String,
+    currency_symbol String,
+    status String,
+    page_count UInt16,
+    dish_count UInt16
+) ENGINE = MergeTree ORDER BY id;
+
+CREATE TABLE menu_page
+(

+) ENGINE = MergeTree ORDER BY id;
+
+CREATE TABLE menu_item

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

+    menu.id AS menu_id,
+    menu.name AS menu_name,
+    menu.sponsor AS menu_sponsor,

+FROM menu_item
+    JOIN dish ON menu_item.dish_id = dish.id

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

+## 下载并解压数据集
+
+1. 进入下载页面[https://recipenlg.cs.put.poznan.pl/dataset](https://recipenlg.cs.put.poznan.pl/dataset)。 
+2. 接受条款和条件并下载 zip 文件。 
+3. 使用 `unzip` 解压 zip 文件，得到 `full_dataset.csv` 文件。
+
+## 创建表
+
+运行 clickhouse-client 并执行以下 CREATE 请求：
+
+``` sql
+CREATE TABLE recipes
+(
+    title String,
+    ingredients Array(String),
+    directions Array(String),
+    link String,
+    source LowCardinality(String),
+    NER Array(String)
+) ENGINE = MergeTree ORDER BY title;
+```
+
+## 插入数据
+
+运行以下命令：
+
+``` bash
+clickhouse-client --query "
+    INSERT INTO recipes
+    SELECT
+        title,
+        JSONExtract(ingredients, 'Array(String)'),
+        JSONExtract(directions, 'Array(String)'),
+        link,
+        source,
+        JSONExtract(NER, 'Array(String)')
+    FROM input('num UInt32, title String, ingredients String, directions String, link String, source LowCardinality(String), NER String')
+    FORMAT CSVWithNames
+" --input_format_with_names_use_header 0 --format_csv_allow_single_quote 0 --input_format_allow_errors_num 10 < full_dataset.csv
+```
+
+这是一个展示如何解析自定义 CSV，这其中涉及了许多调整。
+
+说明： 
+- 数据集为 CSV 格式，但在插入时需要一些预处理；使用表函数 [input](../../sql-reference/table-functions/input.md) 进行预处理； 
+- CSV 文件的结构在表函数 `input` 的参数中指定； 
+- 字段 `num`（行号）是不需要的 - 可以忽略并从文件中进行解析； 
+- 使用 `FORMAT CSVWithNames`，因为标题不包含第一个字段的名称，因此 CSV 中的标题将被忽略（通过命令行参数 `--input_format_with_names_use_header 0`）； 
+- 文件仅使用双引号将 CSV 字符串括起来；一些字符串没有用双引号括起来，单引号也不能被解析为括起来的字符串 - 所以添加`--format_csv_allow_single_quote 0`参数接受文件中的单引号； 
+- 由于某些 CSV 的字符串的开头包含 `\M/` 因此无法被解析； CSV 中唯一可能以反斜杠开头的值是 `\N`，这个值被解析为 SQL NULL。通过添加`--input_format_allow_errors_num 10`参数，允许在导入过程中跳过 10 个格式错误； 
+- 在数据集中的 Ingredients、directions 和 NER 字段为数组；但这些数组并没有以一般形式表示：这些字段作为 JSON 序列化为字符串，然后放入 CSV 中 - 在导入是将它们解析为字符串，然后使用 [JSONExtract](../../sql-reference/functions/json-functions.md ) 函数将其转换为数组。
+
+## 验证插入的数据
+
+通过检查行数：
+
+请求：
+
+``` sql
+SELECT count() FROM recipes;
+```
+
+结果：
+
+``` text

+## 创建表 {#create-table}
+
+```sql
+CREATE TABLE uk_price_paid
+(
+    price UInt32,
+    date Date,
+    postcode1 LowCardinality(String),
+    postcode2 LowCardinality(String),
+    type Enum8('terraced' = 1, 'semi-detached' = 2, 'detached' = 3, 'flat' = 4, 'other' = 0),
+    is_new UInt8,
+    duration Enum8('freehold' = 1, 'leasehold' = 2, 'unknown' = 0),
+    addr1 String,
+    addr2 String,
+    street LowCardinality(String),
+    locality LowCardinality(String),
+    town LowCardinality(String),
+    district LowCardinality(String),
+    county LowCardinality(String)
+)
+ENGINE = MergeTree
+ORDER BY (postcode1, postcode2, addr1, addr2);
+```
+
+## 预处理和插入数据 {#preprocess-import-data}
+
+我们将使用 `url` 函数将数据流式传输到 ClickHouse。我们需要首先预处理一些传入的数据，其中包括： 
+
+- 将`postcode` 拆分为两个不同的列 - `postcode1` 和 `postcode2`，因为这更适合存储和查询 
+- 将`time` 字段转换为日期为它只包含 00:00 时间 
+- 忽略 [UUid](/docs/zh/sql-reference/data-types/uuid.md) 字段，因为我们不需要它进行分析 
+- 使用 [transform](/docs/zh/sql-reference/functions/other-functions.md#transform) 函数将 `Enum` 字段 `type` 和 `duration` 转换为更易读的 `Enum` 字段 
+- 将 `is_new` 字段从单字符串（` Y`/`N`) 到 [UInt8](/docs/zh/sql-reference/data-types/int-uint.md#uint8-uint16-uint32-uint64-uint256-int8-int16-int32-int64 -int128-int256) 字段为 0 或 1 
+- 删除最后两列，因为它们都具有相同的值（即 0）
+
+`url` 函数将来自网络服务器的数据流式传输到 ClickHouse 表中。以下命令将 500 万行插入到 `uk_price_paid` 表中：
+
+```sql
+INSERT INTO uk_price_paid
+WITH
+   splitByChar(' ', postcode) AS p
+SELECT
+    toUInt32(price_string) AS price,
+    parseDateTimeBestEffortUS(time) AS date,
+    p[1] AS postcode1,
+    p[2] AS postcode2,
+    transform(a, ['T', 'S', 'D', 'F', 'O'], ['terraced', 'semi-detached', 'detached', 'flat', 'other']) AS type,
+    b = 'Y' AS is_new,
+    transform(c, ['F', 'L', 'U'], ['freehold', 'leasehold', 'unknown']) AS duration,
+    addr1,
+    addr2,
+    street,
+    locality,
+    town,
+    district,
+    county
+FROM url(
+    'http://prod.publicdata.landregistry.gov.uk.s3-website-eu-west-1.amazonaws.com/pp-complete.csv',
+    'CSV',
+    'uuid_string String,
+    price_string String,
+    time String,
+    postcode String,
+    a String,
+    b String,
+    c String,
+    addr1 String,
+    addr2 String,
+    street String,
+    locality String,
+    town String,
+    district String,
+    county String,
+    d String,
+    e String'
+) SETTINGS max_http_get_redirects=10;
+```
+
+需要等待一两分钟以便数据插入，具体时间取决于网络速度。
+
+## 验证数据 {#validate-data}
+
+让我们通过查看插入了多少行来验证它是否有效：
+
+```sql
+SELECT count()
+FROM uk_price_paid
+```
+
+在执行此查询时，数据集有 27,450,499 行。让我们看看 ClickHouse 中表的大小是多少：
+
+```sql
+SELECT formatReadableSize(total_bytes)
+FROM system.tables
+WHERE name = 'uk_price_paid'
+```
+
+请注意，表的大小仅为 221.43 MiB！
+
+## 运行一些查询 {#run-queries}
+
+让我们运行一些查询来分析数据：
+
+### 查询 1. 每年平均价格 {#average-price}
+
+```sql
+SELECT
+   toYear(date) AS year,
+   round(avg(price)) AS price,
+   bar(price, 0, 1000000, 80
+)
+FROM uk_price_paid
+GROUP BY year
+ORDER BY year
+```
+
+结果如下所示：
+

+## 使用 Projection 加速查询 {#speedup-with-projections}
+
+[Projections](/docs/zh/sql-reference/statements/alter/projection.mdx) 允许我们通过存储任意格式的预先聚合的数据来提高查询速度。在此示例中，我们创建了一个按年份、地区和城镇分组的房产的平均价格、总价格和数量的 Projection。在执行时，如果 ClickHouse 认为 Projection 可以提高查询的性能，它将使用 Projection（何时使用由 ClickHouse 决定）。
+
+### 构建投影{#build-projection}
+
+让我们通过维度 `toYear(date)`、`district` 和 `town` 创建一个聚合 Projection：
+
+```sql
+ALTER TABLE uk_price_paid
+    ADD PROJECTION projection_by_year_district_town
+    (
+        SELECT
+            toYear(date),
+            district,
+            town,
+            avg(price),
+            sum(price),
+            count()
+        GROUP BY
+            toYear(date),
+            district,
+            town
+    )
+```
+
+填充现有数据的 Projection。 （如果不进行 materialize 操作，则 ClickHouse 只会为新插入的数据创建 Projection）：
+
+```sql
+ALTER TABLE uk_price_paid
+    MATERIALIZE PROJECTION projection_by_year_district_town
+SETTINGS mutations_sync = 1
+```
+
+## Test Performance {#test-performance}
+
+让我们再次运行相同的 3 个查询：
+
+### 查询 1. 每年平均价格 {#average-price-projections}
+
+```sql
+SELECT
+    toYear(date) AS year,
+    round(avg(price)) AS price,
+    bar(price, 0, 1000000, 80)
+FROM uk_price_paid
+GROUP BY year
+ORDER BY year ASC
+```
+
+结果是一样的，但是性能更好！

+### 查询 2. 伦敦每年的平均价格 {#average-price-london-projections}
+
+```sql
+SELECT
+    toYear(date) AS year,
+    round(avg(price)) AS price,
+    bar(price, 0, 2000000, 100)
+FROM uk_price_paid
+WHERE town = 'LONDON'
+GROUP BY year
+ORDER BY year ASC
+```
+
+Same result, but notice the improvement in query performance:
+
+```response
+No projection:   28 rows in set. Elapsed: 0.720 sec. Processed 27.45 million rows, 46.61 MB (38.13 million rows/s., 64.74 MB/s.)

+```
+
+### 查询 3. 最昂贵的社区 {#most-expensive-neighborhoods-projections}
+
+注意：需要修改 (date >= '2020-01-01') 以使其与 Projection 定义的维度 (`toYear(date) >= 2020)` 匹配：
+
+```sql
+SELECT
+    town,
+    district,
+    count() AS c,
+    round(avg(price)) AS price,
+    bar(price, 0, 5000000, 100)
+FROM uk_price_paid
+WHERE toYear(date) >= 2020
+GROUP BY
+    town,
+    district
+HAVING c >= 100
+ORDER BY price DESC
+LIMIT 100
+```
+
+同样，结果是相同的，但请注意查询性能的改进：
+
+```response
+No projection:   100 rows in set. Elapsed: 0.928 sec. Processed 27.45 million rows, 103.80 MB (29.56 million rows/s., 111.80 MB/s.)
