 #### Upgrade Notes
+* The `SYSTEM RESTART DISK` query becomes a no-op. [#44647](https://github.com/ClickHouse/ClickHouse/pull/44647) ([alesapin](https://github.com/alesapin)).
+* The `PREALLOCATE` option for `HASHED`/`SPARSE_HASHED` dictionaries becomes a no-op. [#45388](https://github.com/ClickHouse/ClickHouse/pull/45388) ([Azat Khuzhin](https://github.com/azat)). It does not give significant advantages anymore.
+* Disallow `Gorilla` codec on columns of non-Float32 or non-Float64 type. [#45252](https://github.com/ClickHouse/ClickHouse/pull/45252) ([Robert Schulze](https://github.com/rschu1ze)). It was pointless and led to inconsistencies. 
+* Parallel quorum inserts might work incorrectly with `*MergeTree` tables created with the deprecated syntax. Therefore, parallel quorum inserts support is completely disabled for such tables. It does not affect tables created with a new syntax. [#45430](https://github.com/ClickHouse/ClickHouse/pull/45430) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Use the `GetObjectAttributes` request instead of the `HeadObject` request to get the size of an object in AWS S3. This change fixes handling endpoints without explicit regions after updating the AWS SDK, for example. [#45288](https://github.com/ClickHouse/ClickHouse/pull/45288) ([Vitaly Baranov](https://github.com/vitlibar)). AWS S3 and Minio are tested, but keep in mind that various S3-compatible services (GCS, R2, B2) may have subtle incompatibilities. This change also may require you to adjust the ACL to allow the `GetObjectAttributes` request.
+* Forbid paths in timezone names. For example, a timezone name like `/usr/share/zoneinfo/Asia/Aden` is not allowed; the IANA timezone database name like `Asia/Aden` should be used. [#44225](https://github.com/ClickHouse/ClickHouse/pull/44225) ([Kruglov Pavel](https://github.com/Avogar)).
+* Queries combining equijoin and constant expressions (e.g., `JOIN ON t1.x = t2.x AND 1 = 1`) are forbidden due to incorrect results. [#44016](https://github.com/ClickHouse/ClickHouse/pull/44016) ([Vladimir C](https://github.com/vdimir)).
 
-* Now, background merges, mutations and `OPTIMIZE` will not increment `SelectedRows` and `SelectedBytes` metrics. They (still) will increment `MergedRows` and `MergedUncompressedBytes` as it was before. This only affects the metric values, and makes them better. This change does not introduce any incompatibility, but you may wonder about the changes of metrics, so we put in this category. [#37040](https://github.com/ClickHouse/ClickHouse/pull/37040) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
-* Updated the BoringSSL module to the official FIPS compliant version. This makes ClickHouse FIPS compliant. [#35914](https://github.com/ClickHouse/ClickHouse/pull/35914) ([Meena-Renganathan](https://github.com/Meena-Renganathan)). The ciphers `aes-192-cfb128` and `aes-256-cfb128` were removed, because they are not included in the FIPS certified version of BoringSSL.
-* `max_memory_usage` setting is removed from the default user profile in `users.xml`. This enables flexible memory limits for queries instead of the old rigid limit of 10 GB.
-* Disable `log_query_threads` setting by default. It controls the logging of statistics about every thread participating in query execution. After supporting asynchronous reads, the total number of distinct thread ids became too large, and logging into the `query_thread_log` has become too heavy. [#37077](https://github.com/ClickHouse/ClickHouse/pull/37077) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-* Remove function `groupArraySorted` which has a bug. [#36822](https://github.com/ClickHouse/ClickHouse/pull/36822) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
 
 #### New Feature
-
-* Enable memory overcommit by default. [#35921](https://github.com/ClickHouse/ClickHouse/pull/35921) ([Dmitry Novik](https://github.com/novikd)).
-* Add support of GROUPING SETS in GROUP BY clause. This implementation supports a parallel processing of grouping sets. [#33631](https://github.com/ClickHouse/ClickHouse/pull/33631) ([Dmitry Novik](https://github.com/novikd)).
-* Added `system.certificates` table. [#37142](https://github.com/ClickHouse/ClickHouse/pull/37142) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
-* Adds `h3Line`, `h3Distance` and `h3HexRing` functions. [#37030](https://github.com/ClickHouse/ClickHouse/pull/37030) ([Bharat Nallan](https://github.com/bharatnc)).
-* New single binary based diagnostics tool (clickhouse-diagnostics). [#36705](https://github.com/ClickHouse/ClickHouse/pull/36705) ([Dale McDiarmid](https://github.com/gingerwizard)).

-* Add `MySQLDump` input format. It reads all data from INSERT queries belonging to one table in dump. If there are more than one table, by default it reads data from the first one. [#36667](https://github.com/ClickHouse/ClickHouse/pull/36667) ([Kruglov Pavel](https://github.com/Avogar)).
-* Show the `total_rows` and `total_bytes` fields in `system.tables` for temporary tables. [#36401](https://github.com/ClickHouse/ClickHouse/issues/36401). [#36439](https://github.com/ClickHouse/ClickHouse/pull/36439) ([xiedeyantu](https://github.com/xiedeyantu)).
-* Allow to override `parts_to_delay_insert` and `parts_to_throw_insert` with query-level settings. If they are defined, they will override table-level settings. [#36371](https://github.com/ClickHouse/ClickHouse/pull/36371) ([Memo](https://github.com/Joeywzr)).
+* Dictionary source for extracting keys by traversing regular expressions tree. It can be used for User-Agent parsing. [#40878](https://github.com/ClickHouse/ClickHouse/pull/40878) ([Vage Ogannisian](https://github.com/nooblose)). [#43858](https://github.com/ClickHouse/ClickHouse/pull/43858) ([Han Fei](https://github.com/hanfei1991)).
+* Added parametrized view functionality, now it's possible to specify query parameters for the View table engine. resolves [#40907](https://github.com/ClickHouse/ClickHouse/issues/40907). [#41687](https://github.com/ClickHouse/ClickHouse/pull/41687) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Add `quantileInterpolatedWeighted`/`quantilesInterpolatedWeighted` functions. [#38252](https://github.com/ClickHouse/ClickHouse/pull/38252) ([Bharat Nallan](https://github.com/bharatnc)).
+* Array join support for the `Map` type, like the function "explode" in Spark. [#43239](https://github.com/ClickHouse/ClickHouse/pull/43239) ([李扬](https://github.com/taiyang-li)).
+* Support SQL standard binary and hex string literals. [#43785](https://github.com/ClickHouse/ClickHouse/pull/43785) ([Mo Xuan](https://github.com/mo-avatar)).
+* Allow formatting `DateTime` in Joda-Time style. Refer to [the Joda-Time docs](https://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html). [#43818](https://github.com/ClickHouse/ClickHouse/pull/43818) ([李扬](https://github.com/taiyang-li)).
+* Implemented a fractional second formatter (`%f`) for `formatDateTime`. [#44060](https://github.com/ClickHouse/ClickHouse/pull/44060) ([ltrk2](https://github.com/ltrk2)). [#44497](https://github.com/ClickHouse/ClickHouse/pull/44497) ([Alexander Gololobov](https://github.com/davenger)).
+* Added `age` function to calculate the difference between two dates or dates with time values expressed as the number of full units. Closes [#41115](https://github.com/ClickHouse/ClickHouse/issues/41115). [#44421](https://github.com/ClickHouse/ClickHouse/pull/44421) ([Robert Schulze](https://github.com/rschu1ze)).
+* Add `Null` source for dictionaries. Closes [#44240](https://github.com/ClickHouse/ClickHouse/issues/44240). [#44502](https://github.com/ClickHouse/ClickHouse/pull/44502) ([mayamika](https://github.com/mayamika)).
+* Allow configuring the S3 storage class with the `s3_storage_class` configuration option. Such as `<s3_storage_class>STANDARD/INTELLIGENT_TIERING</s3_storage_class>` Closes [#44443](https://github.com/ClickHouse/ClickHouse/issues/44443). [#44707](https://github.com/ClickHouse/ClickHouse/pull/44707) ([chen](https://github.com/xiedeyantu)).
+* Insert default values in case of missing elements in JSON object while parsing named tuple. Add setting `input_format_json_defaults_for_missing_elements_in_named_tuple` that controls this behaviour. Closes [#45142](https://github.com/ClickHouse/ClickHouse/issues/45142)#issuecomment-1380153217. [#45231](https://github.com/ClickHouse/ClickHouse/pull/45231) ([Kruglov Pavel](https://github.com/Avogar)).
+* Record server startup time in ProfileEvents (`ServerStartupMilliseconds`). Resolves [#43188](https://github.com/ClickHouse/ClickHouse/issues/43188). [#45250](https://github.com/ClickHouse/ClickHouse/pull/45250) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Refactor and Improve streaming engines Kafka/RabbitMQ/NATS and add support for all formats, also refactor formats a bit: - Fix producing messages in row-based formats with suffixes/prefixes. Now every message is formatted completely with all delimiters and can be parsed back using input format. - Support block-based formats like Native, Parquet, ORC, etc. Every block is formatted as a separate message. The number of rows in one message depends on the block size, so you can control it via the setting `max_block_size`. - Add new engine settings `kafka_max_rows_per_message/rabbitmq_max_rows_per_message/nats_max_rows_per_message`. They control the number of rows formatted in one message in row-based formats. Default value: 1. - Fix high memory consumption in the NATS table engine. - Support arbitrary binary data in NATS producer (previously it worked only with strings contained \0 at the end) - Add missing Kafka/RabbitMQ/NATS engine settings in the documentation. - Refactor producing and consuming in Kafka/RabbitMQ/NATS, separate it from WriteBuffers/ReadBuffers semantic. - Refactor output formats: remove callbacks on each row used in Kafka/RabbitMQ/NATS (now we don't use callbacks there), allow to use IRowOutputFormat directly, clarify row end and row between delimiters, make it possible to reset output format to start formatting again - Add proper implementation in formatRow function (bonus after formats refactoring). [#42777](https://github.com/ClickHouse/ClickHouse/pull/42777) ([Kruglov Pavel](https://github.com/Avogar)).
+* Support reading/writing `Nested` tables as `List` of `Struct` in `CapnProto` format. Read/write `Decimal32/64` as `Int32/64`. Closes [#43319](https://github.com/ClickHouse/ClickHouse/issues/43319). [#43379](https://github.com/ClickHouse/ClickHouse/pull/43379) ([Kruglov Pavel](https://github.com/Avogar)).
+* Added a `message_format_string` column to `system.text_log`. The column contains a pattern that was used to format the message. [#44543](https://github.com/ClickHouse/ClickHouse/pull/44543) ([Alexander Tokmakov](https://github.com/tavplubix)). This allows various analytics over the ClickHouse logs.
+* Try to autodetect headers with column names (and maybe types) for CSV/TSV/CustomSeparated input formats.
+Add settings input_format_tsv/csv/custom_detect_header that enable this behaviour (enabled by default). Closes [#44640](https://github.com/ClickHouse/ClickHouse/issues/44640). [#44953](https://github.com/ClickHouse/ClickHouse/pull/44953) ([Kruglov Pavel](https://github.com/Avogar)).
 
 #### Experimental Feature
-
-* Implemented L1, L2, Linf, Cosine distance functions for arrays and L1, L2, Linf norm functions for arrays.
- [#37033](https://github.com/ClickHouse/ClickHouse/pull/37033) ([qieqieplus](https://github.com/qieqieplus)). Caveat: the functions will be renamed.
-* Improve the `WATCH` query in WindowView: 1. Reduce the latency of providing query results by calling the `fire_condition` signal. 2. Makes the cancel query operation(ctrl-c) faster, by checking `isCancelled()` more frequently. [#37226](https://github.com/ClickHouse/ClickHouse/pull/37226) ([vxider](https://github.com/Vxider)).
-* Introspection for remove filesystem cache. [#36802](https://github.com/ClickHouse/ClickHouse/pull/36802) ([Han Shukai](https://github.com/KinderRiven)).
-* Added new hash function `wyHash64` for SQL. [#36467](https://github.com/ClickHouse/ClickHouse/pull/36467) ([olevino](https://github.com/olevino)).
-* Improvement for replicated databases: Added `SYSTEM SYNC DATABASE REPLICA` query which allows to sync tables metadata inside Replicated database, because currently synchronisation is asynchronous. [#35944](https://github.com/ClickHouse/ClickHouse/pull/35944) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* Improvement for remote filesystem cache: Better read from cache. [#37054](https://github.com/ClickHouse/ClickHouse/pull/37054) ([Kseniia Sumarokova](https://github.com/kssenii)). Improve `SYSTEM DROP FILESYSTEM CACHE` query: `<path>` option and `FORCE` option. [#36639](https://github.com/ClickHouse/ClickHouse/pull/36639) ([Kseniia Sumarokova](https://github.com/kssenii)).
-* Improvement for semistructured data: Allow to cast columns of type `Object(...)` to `Object(Nullable(...))`. [#36564](https://github.com/ClickHouse/ClickHouse/pull/36564) ([awakeljw](https://github.com/awakeljw)).
-* Improvement for parallel replicas: We create a local interpreter if we want to execute query on localhost replica. But for when executing query on multiple replicas we rely on the fact that a connection exists so replicas can talk to coordinator. It is now improved and localhost replica can talk to coordinator directly in the same process. [#36281](https://github.com/ClickHouse/ClickHouse/pull/36281) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Add an experimental inverted index as a new secondary index type for efficient text search. [#38667](https://github.com/ClickHouse/ClickHouse/pull/38667) ([larryluogit](https://github.com/larryluogit)).
+* Add experimental query result cache. [#43797](https://github.com/ClickHouse/ClickHouse/pull/43797) ([Robert Schulze](https://github.com/rschu1ze)).
+* Added extendable and configurable scheduling subsystem for IO requests (not yet integrated with IO code itself). [#41840](https://github.com/ClickHouse/ClickHouse/pull/41840) ([Sergei Trifonov](https://github.com/serxa)). This feature does nothing at all, enjoy.
+* Added `SYSTEM DROP DATABASE REPLICA` that removes metadata of a dead replica of a `Replicated` database. Resolves [#41794](https://github.com/ClickHouse/ClickHouse/issues/41794). [#42807](https://github.com/ClickHouse/ClickHouse/pull/42807) ([Alexander Tokmakov](https://github.com/tavplubix)).
 
 #### Performance Improvement
-
-* Improve performance of `avg`, `sum` aggregate functions if used without GROUP BY expression. [#37257](https://github.com/ClickHouse/ClickHouse/pull/37257) ([Maksim Kita](https://github.com/kitaisreal)).
-* Improve performance of unary arithmetic functions (`bitCount`, `bitNot`, `abs`, `intExp2`, `intExp10`, `negate`, `roundAge`, `roundDuration`, `roundToExp2`, `sign`) using dynamic dispatch. [#37289](https://github.com/ClickHouse/ClickHouse/pull/37289) ([Maksim Kita](https://github.com/kitaisreal)).
-* Improve performance of ORDER BY, MergeJoin, insertion into MergeTree using JIT compilation of sort columns comparator. [#34469](https://github.com/ClickHouse/ClickHouse/pull/34469) ([Maksim Kita](https://github.com/kitaisreal)).
-* Change structure of `system.asynchronous_metric_log`. It will take about 10 times less space. This closes [#36357](https://github.com/ClickHouse/ClickHouse/issues/36357). The field `event_time_microseconds` was removed, because it is useless. [#36360](https://github.com/ClickHouse/ClickHouse/pull/36360) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-* Load marks for only necessary columns when reading wide parts. [#36879](https://github.com/ClickHouse/ClickHouse/pull/36879) ([Anton Kozlov](https://github.com/tonickkozlov)).
-* Improves performance of file descriptor cache by narrowing mutex scopes. [#36682](https://github.com/ClickHouse/ClickHouse/pull/36682) ([Anton Kozlov](https://github.com/tonickkozlov)).
-* Improve performance of reading from storage `File` and table functions `file` in case when path has globs and matched directory contains large number of files. [#36647](https://github.com/ClickHouse/ClickHouse/pull/36647) ([Anton Popov](https://github.com/CurtizJ)).
-* Apply parallel parsing for input format `HiveText`, which can speed up HiveText parsing by 2x when reading local file. [#36650](https://github.com/ClickHouse/ClickHouse/pull/36650) ([李扬](https://github.com/taiyang-li)).
-* The default `HashJoin` is not thread safe for inserting right table's rows and run it in a single thread. When the right table is large, the join process is too slow with low cpu utilization. [#36415](https://github.com/ClickHouse/ClickHouse/pull/36415) ([lgbo](https://github.com/lgbo-ustc)).
-* Allow to rewrite `select countDistinct(a) from t` to `select count(1) from (select a from t groupBy a)`. [#35993](https://github.com/ClickHouse/ClickHouse/pull/35993) ([zhanglistar](https://github.com/zhanglistar)).
-* Transform OR LIKE chain to multiMatchAny. Will enable once we have more confidence it works. [#34932](https://github.com/ClickHouse/ClickHouse/pull/34932) ([Daniel Kutenin](https://github.com/danlark1)).
-* Improve performance of some functions with inlining. [#34544](https://github.com/ClickHouse/ClickHouse/pull/34544) ([Daniel Kutenin](https://github.com/danlark1)).
-* Add a branch to avoid unnecessary memcpy in readBig. It improves performance somewhat. [#36095](https://github.com/ClickHouse/ClickHouse/pull/36095) ([jasperzhu](https://github.com/jinjunzh)).
-* Implement partial GROUP BY key for optimize_aggregation_in_order. [#35111](https://github.com/ClickHouse/ClickHouse/pull/35111) ([Azat Khuzhin](https://github.com/azat)).
+* Do not load inactive parts at startup of `MergeTree` tables. [#42181](https://github.com/ClickHouse/ClickHouse/pull/42181) ([Anton Popov](https://github.com/CurtizJ)).
+* Improved latency of reading from storage `S3` and table function `s3` with large numbers of small files. Now settings `remote_filesystem_read_method` and `remote_filesystem_read_prefetch` take effect while reading from storage `S3`. [#43726](https://github.com/ClickHouse/ClickHouse/pull/43726) ([Anton Popov](https://github.com/CurtizJ)).
+* Optimization for reading struct fields in Parquet/ORC files. Only the required fields are loaded. [#44484](https://github.com/ClickHouse/ClickHouse/pull/44484) ([lgbo](https://github.com/lgbo-ustc)).
+* Two-level aggregation algorithm was mistakenly disabled for queries over the HTTP interface. It was enabled back, and it leads to a major performance improvement. [#45450](https://github.com/ClickHouse/ClickHouse/pull/45450) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Added mmap support for StorageFile, which should improve the performance of clickhouse-local. [#43927](https://github.com/ClickHouse/ClickHouse/pull/43927) ([pufit](https://github.com/pufit)).
+* Added sharding support in HashedDictionary to allow parallel load (almost linear scaling based on number of shards). [#40003](https://github.com/ClickHouse/ClickHouse/pull/40003) ([Azat Khuzhin](https://github.com/azat)).
+* Speed up query parsing. [#42284](https://github.com/ClickHouse/ClickHouse/pull/42284) ([Raúl Marín](https://github.com/Algunenano)).
+* Always replace OR chain `expr = x1 OR ... OR expr = xN` to `expr IN (x1, ..., xN)` in the case where `expr` is a `LowCardinality` column. Setting `optimize_min_equality_disjunction_chain_length` is ignored in this case. [#42889](https://github.com/ClickHouse/ClickHouse/pull/42889) ([Guo Wangyang](https://github.com/guowangy)).
+* Slightly improve performance by optimizing the code around ThreadStatus. [#43586](https://github.com/ClickHouse/ClickHouse/pull/43586) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Optimize the column-wise ternary logic evaluation by achieving auto-vectorization. In the performance test of this [microbenchmark](https://github.com/ZhiguoZh/ClickHouse/blob/20221123-ternary-logic-opt-example/src/Functions/examples/associative_applier_perf.cpp), we've observed a peak **performance gain** of **21x** on the ICX device (Intel Xeon Platinum 8380 CPU). [#43669](https://github.com/ClickHouse/ClickHouse/pull/43669) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Avoid acquiring read locks in the `system.tables` table if possible. [#43840](https://github.com/ClickHouse/ClickHouse/pull/43840) ([Raúl Marín](https://github.com/Algunenano)).
+* Optimize ThreadPool. 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 effectively decrease the lock contention for ThreadPoolImpl::mutex by **75%**, increasing the CPU utilization and improving the overall performance by **2.4%**. [#44308](https://github.com/ClickHouse/ClickHouse/pull/44308) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Now the optimisation for predicting the hash table size is applied only if the cached hash table size is sufficiently large (thresholds were determined empirically and hardcoded). [#44455](https://github.com/ClickHouse/ClickHouse/pull/44455) ([Nikita Taranov](https://github.com/nickitat)).
+* Small performance improvement for asynchronous reading from remote filesystems. [#44868](https://github.com/ClickHouse/ClickHouse/pull/44868) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add fast path for: - `col like '%%'`; - `col like '%'`; - `col not like '%'`; - `col not like '%'`; - `match(col, '.*')`. [#45244](https://github.com/ClickHouse/ClickHouse/pull/45244) ([李扬](https://github.com/taiyang-li)).
+* Slightly improve happy path optimisation in filtering (WHERE clause). [#45289](https://github.com/ClickHouse/ClickHouse/pull/45289) ([Nikita Taranov](https://github.com/nickitat)).
+* Provide monotonicity info for `toUnixTimestamp64*` to enable more algebraic optimizations for index analysis. [#44116](https://github.com/ClickHouse/ClickHouse/pull/44116) ([Nikita Taranov](https://github.com/nickitat)).
+* Allow the configuration of temporary data for query processing (spilling to disk) to cooperate with the filesystem cache (taking up the space from the cache disk) [#43972](https://github.com/ClickHouse/ClickHouse/pull/43972) ([Vladimir C](https://github.com/vdimir)). This mainly improves [ClickHouse Cloud](https://clickhouse.cloud/), but can be used for self-managed setups as well, if you know what to do.
+* Make `system.replicas` table do parallel fetches of replicas statuses. Closes [#43918](https://github.com/ClickHouse/ClickHouse/issues/43918). [#43998](https://github.com/ClickHouse/ClickHouse/pull/43998) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Optimize memory consumption during backup to S3: files to S3 now will be copied directly without using `WriteBufferFromS3` (which could use a lot of memory). [#45188](https://github.com/ClickHouse/ClickHouse/pull/45188) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Add a cache for async block ids. This will reduce the number of requests of ZooKeeper when we enable async inserts deduplication. [#45106](https://github.com/ClickHouse/ClickHouse/pull/45106) ([Han Fei](https://github.com/hanfei1991)).
 
 #### Improvement
 
-* Show names of erroneous files in case of parsing errors while executing table functions `file`, `s3` and `url`. [#36314](https://github.com/ClickHouse/ClickHouse/pull/36314) ([Anton Popov](https://github.com/CurtizJ)).
-* Allowed to increase the number of threads for executing background operations (merges, mutations, moves and fetches) at runtime if they are specified at top level config. [#36425](https://github.com/ClickHouse/ClickHouse/pull/36425) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* Now date time conversion functions that generates time before 1970-01-01 00:00:00 with partial hours/minutes timezones will be saturated to zero instead of overflow. This is the continuation of https://github.com/ClickHouse/ClickHouse/pull/29953 which addresses https://github.com/ClickHouse/ClickHouse/pull/29953#discussion_r800550280 . Mark as improvement because it's implementation defined behavior (and very rare case) and we are allowed to break it. [#36656](https://github.com/ClickHouse/ClickHouse/pull/36656) ([Amos Bird](https://github.com/amosbird)).
-* Add a warning if someone running clickhouse-server with log level "test".

-* If the required amount of memory is available before the selected query stopped, all waiting queries continue execution. Now we don't stop any query if memory is freed before the moment when the selected query knows about the cancellation. [#35637](https://github.com/ClickHouse/ClickHouse/pull/35637) ([Dmitry Novik](https://github.com/novikd)).
-* Nullables detection in protobuf. In proto3, default values are not sent on the wire. This makes it non-trivial to distinguish between null and default values for Nullable columns. A standard way to deal with this problem is to use Google wrappers to nest the target value within an inner message (see https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/wrappers.proto). In this case, a missing field is interpreted as null value, a field with missing value if interpreted as default value, and a field with regular value is interpreted as regular value. However, ClickHouse interprets Google wrappers as nested columns. We propose to introduce special behaviour to detect Google wrappers and interpret them like in the description above. For example, to serialize values for a Nullable column `test`, we would use `google.protobuf.StringValue test` in our .proto schema. Note that these types are so called "well-known types" in Protobuf, implemented in the library itself. [#35149](https://github.com/ClickHouse/ClickHouse/pull/35149) ([Jakub Kuklis](https://github.com/jkuklis)).
-* Added support for specifying `content_type` in predefined and static HTTP handler config. [#34916](https://github.com/ClickHouse/ClickHouse/pull/34916) ([Roman Nikonov](https://github.com/nic11)).

-* Improve MySQL database engine to compatible with binary(0) dataType. [#37232](https://github.com/ClickHouse/ClickHouse/pull/37232) ([zzsmdfj](https://github.com/zzsmdfj)).
-* Improve JSON report of clickhouse-benchmark. [#36473](https://github.com/ClickHouse/ClickHouse/pull/36473) ([Tian Xinhui](https://github.com/xinhuitian)).
-* Server might refuse to start if it cannot resolve hostname of external ClickHouse dictionary. It's fixed. Fixes [#36451](https://github.com/ClickHouse/ClickHouse/issues/36451). [#36463](https://github.com/ClickHouse/ClickHouse/pull/36463) ([tavplubix](https://github.com/tavplubix)).

+* Remove redundant sorting, for example, sorting related ORDER BY clauses in subqueries. Implemented on top of query plan. It does similar optimization as `optimize_duplicate_order_by_and_distinct` regarding `ORDER BY` clauses, but more generic, since it's applied to any redundant sorting steps (not only caused by ORDER BY clause) and applied to subqueries of any depth. Related to [#42648](https://github.com/ClickHouse/ClickHouse/issues/42648). [#43905](https://github.com/ClickHouse/ClickHouse/pull/43905) ([Igor Nikonov](https://github.com/devcrafter)).

-### <a id="224"></a> ClickHouse release 22.4, 2022-04-19
-
-#### Backward Incompatible Change
-
-* Do not allow SETTINGS after FORMAT for INSERT queries (there is compatibility setting `parser_settings_after_format_compact` to accept such queries, but it is turned OFF by default). [#35883](https://github.com/ClickHouse/ClickHouse/pull/35883) ([Azat Khuzhin](https://github.com/azat)).
-* Function `yandexConsistentHash` (consistent hashing algorithm by Konstantin "kostik" Oblakov) is renamed to `kostikConsistentHash`. The old name is left as an alias for compatibility. Although this change is backward compatible, we may remove the alias in subsequent releases, that's why it's recommended to update the usages of this function in your apps. [#35553](https://github.com/ClickHouse/ClickHouse/pull/35553) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-
-#### New Feature
-
-* Added INTERPOLATE extension to the ORDER BY ... WITH FILL. Closes [#34903](https://github.com/ClickHouse/ClickHouse/issues/34903). [#35349](https://github.com/ClickHouse/ClickHouse/pull/35349) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
-* Profiling on Processors level (under `log_processors_profiles` setting, ClickHouse will write time that processor spent during execution/waiting for data to `system.processors_profile_log` table). [#34355](https://github.com/ClickHouse/ClickHouse/pull/34355) ([Azat Khuzhin](https://github.com/azat)).
-* Added functions makeDate(year, month, day), makeDate32(year, month, day). [#35628](https://github.com/ClickHouse/ClickHouse/pull/35628) ([Alexander Gololobov](https://github.com/davenger)). Implementation of makeDateTime() and makeDateTIme64(). [#35934](https://github.com/ClickHouse/ClickHouse/pull/35934) ([Alexander Gololobov](https://github.com/davenger)).
-* Support new type of quota `WRITTEN BYTES` to limit amount of written bytes during insert queries. [#35736](https://github.com/ClickHouse/ClickHouse/pull/35736) ([Anton Popov](https://github.com/CurtizJ)).
-* Added function `flattenTuple`. It receives nested named `Tuple` as an argument and returns a flatten `Tuple` which elements are the paths from the original `Tuple`. E.g.: `Tuple(a Int, Tuple(b Int, c Int)) -> Tuple(a Int, b Int, c Int)`. `flattenTuple` can be used to select all paths from type `Object` as separate columns. [#35690](https://github.com/ClickHouse/ClickHouse/pull/35690) ([Anton Popov](https://github.com/CurtizJ)).
-* Added functions `arrayFirstOrNull`, `arrayLastOrNull`. Closes [#35238](https://github.com/ClickHouse/ClickHouse/issues/35238). [#35414](https://github.com/ClickHouse/ClickHouse/pull/35414) ([Maksim Kita](https://github.com/kitaisreal)).
-* Added functions `minSampleSizeContinous` and `minSampleSizeConversion`. Author [achimbab](https://github.com/achimbab). [#35360](https://github.com/ClickHouse/ClickHouse/pull/35360) ([Maksim Kita](https://github.com/kitaisreal)).
-* New functions minSampleSizeContinous and minSampleSizeConversion. [#34354](https://github.com/ClickHouse/ClickHouse/pull/34354) ([achimbab](https://github.com/achimbab)).

-* Add `toLastDayOfMonth` function which rounds up a date or date with time to the last day of the month. [#33501](https://github.com/ClickHouse/ClickHouse/issues/33501). [#34394](https://github.com/ClickHouse/ClickHouse/pull/34394) ([Habibullah Oladepo](https://github.com/holadepo)).
-* Added load balancing setting for \[Zoo\]Keeper client. Closes [#29617](https://github.com/ClickHouse/ClickHouse/issues/29617). [#30325](https://github.com/ClickHouse/ClickHouse/pull/30325) ([小路](https://github.com/nicelulu)).
-* Add a new kind of row policies named `simple`. Before this PR we had two kinds or row policies: `permissive` and `restrictive`. A `simple` row policy adds a new filter on a table without any side-effects like it was for permissive and restrictive policies. [#35345](https://github.com/ClickHouse/ClickHouse/pull/35345) ([Vitaly Baranov](https://github.com/vitlibar)).

-* Added sanity checks on server startup (available memory and disk space, max thread count, etc). [#34566](https://github.com/ClickHouse/ClickHouse/pull/34566) ([Sergei Trifonov](https://github.com/serxa)).
-* INTERVAL improvement - can be used with `[MILLI|MICRO|NANO]SECOND`. Added `toStartOf[Milli|Micro|Nano]second()` functions. Added `[add|subtract][Milli|Micro|Nano]seconds()`. [#34353](https://github.com/ClickHouse/ClickHouse/pull/34353) ([Andrey Zvonov](https://github.com/zvonand)).
-
-#### Experimental Feature
-
-* Added support for transactions for simple `MergeTree` tables. This feature is highly experimental and not recommended for production. Part of [#22086](https://github.com/ClickHouse/ClickHouse/issues/22086). [#24258](https://github.com/ClickHouse/ClickHouse/pull/24258) ([tavplubix](https://github.com/tavplubix)).
-* Support schema inference for type `Object` in format `JSONEachRow`. Allow to convert columns of type `Map` to columns of type `Object`. [#35629](https://github.com/ClickHouse/ClickHouse/pull/35629) ([Anton Popov](https://github.com/CurtizJ)).
-* Allow to write remote FS cache on all write operations. Add `system.remote_filesystem_cache` table. Add `drop remote filesystem cache` query. Add introspection for s3 metadata with `system.remote_data_paths` table. Closes [#34021](https://github.com/ClickHouse/ClickHouse/issues/34021). Add cache option for merges by adding mode `read_from_filesystem_cache_if_exists_otherwise_bypass_cache` (turned on by default for merges and can also be turned on by query setting with the same name). Rename cache related settings (`remote_fs_enable_cache -> enable_filesystem_cache`, etc). [#35475](https://github.com/ClickHouse/ClickHouse/pull/35475) ([Kseniia Sumarokova](https://github.com/kssenii)).
-* An option to store parts metadata in RocksDB. Speed up parts loading process of MergeTree to accelerate starting up of clickhouse-server. With this improvement, clickhouse-server was able to decrease starting up time from 75 minutes to 20 seconds, with 700k mergetree parts. [#32928](https://github.com/ClickHouse/ClickHouse/pull/32928) ([李扬](https://github.com/taiyang-li)).
-
-#### Performance Improvement
-
-* A new query plan optimization. Evaluate functions after `ORDER BY` when possible. As an example, for a query `SELECT sipHash64(number) FROM numbers(1e8) ORDER BY number LIMIT 5`, function `sipHash64` would be evaluated after `ORDER BY` and `LIMIT`, which gives ~20x speed up. [#35623](https://github.com/ClickHouse/ClickHouse/pull/35623) ([Nikita Taranov](https://github.com/nickitat)).
-* Sizes of hash tables used during aggregation now collected and used in later queries to avoid hash tables resizes. [#33439](https://github.com/ClickHouse/ClickHouse/pull/33439) ([Nikita Taranov](https://github.com/nickitat)).
-* Improvement for hasAll function using SIMD instructions (SSE and AVX2). [#27653](https://github.com/ClickHouse/ClickHouse/pull/27653) ([youennL-cs](https://github.com/youennL-cs)). [#35723](https://github.com/ClickHouse/ClickHouse/pull/35723) ([Maksim Kita](https://github.com/kitaisreal)).
-* Multiple changes to improve ASOF JOIN performance (1.2 - 1.6x as fast). It also adds support to use big integers. [#34733](https://github.com/ClickHouse/ClickHouse/pull/34733) ([Raúl Marín](https://github.com/Algunenano)).
-* Improve performance of ASOF JOIN if key is native integer. [#35525](https://github.com/ClickHouse/ClickHouse/pull/35525) ([Maksim Kita](https://github.com/kitaisreal)).
-* Parallelization of multipart upload into S3 storage. [#35343](https://github.com/ClickHouse/ClickHouse/pull/35343) ([Sergei Trifonov](https://github.com/serxa)).
-* URL storage engine now downloads multiple chunks in parallel if the endpoint supports HTTP Range. Two additional settings were added, `max_download_threads` and `max_download_buffer_size`, which control maximum number of threads a single query can use to download the file and the maximum number of bytes each thread can process. [#35150](https://github.com/ClickHouse/ClickHouse/pull/35150) ([Antonio Andelic](https://github.com/antonio2368)).
-* Use multiple threads to download objects from S3. Downloading is controllable using `max_download_threads` and `max_download_buffer_size` settings. [#35571](https://github.com/ClickHouse/ClickHouse/pull/35571) ([Antonio Andelic](https://github.com/antonio2368)).
-* Narrow mutex scope when interacting with HDFS. Related to [#35292](https://github.com/ClickHouse/ClickHouse/issues/35292). [#35646](https://github.com/ClickHouse/ClickHouse/pull/35646) ([shuchaome](https://github.com/shuchaome)).
-* Require mutations for per-table TTL only when it had been changed. [#35953](https://github.com/ClickHouse/ClickHouse/pull/35953) ([Azat Khuzhin](https://github.com/azat)).
-
-#### Improvement
-
-* Multiple improvements for schema inference. Use some tweaks and heuristics to determine numbers, strings, arrays, tuples and maps in CSV, TSV and TSVRaw data formats. Add setting `input_format_csv_use_best_effort_in_schema_inference` for CSV format that enables/disables using these heuristics, if it's disabled, we treat everything as string. Add similar setting `input_format_tsv_use_best_effort_in_schema_inference` for TSV/TSVRaw format. These settings are enabled by default. - Add Maps support for schema inference in Values format. - Fix possible segfault in schema inference in Values format. - Allow to skip columns with unsupported types in Arrow/ORC/Parquet formats. Add corresponding settings for it: `input_format_{parquet|orc|arrow}_skip_columns_with_unsupported_types_in_schema_inference`. These settings are disabled by default. - Allow to convert a column with type Null to a Nullable column with all NULL values in Arrow/Parquet formats. - Allow to specify column names in schema inference via setting `column_names_for_schema_inference` for formats that don't contain column names (like CSV, TSV, JSONCompactEachRow, etc) - Fix schema inference in ORC/Arrow/Parquet formats in terms of working with Nullable columns. Previously all inferred types were not Nullable and it blocked reading Nullable columns from data, now it's fixed and all inferred types are always Nullable (because we cannot understand that column is Nullable or not by reading the schema). - Fix schema inference in Template format with CSV escaping rules. [#35582](https://github.com/ClickHouse/ClickHouse/pull/35582) ([Kruglov Pavel](https://github.com/Avogar)).
-* Add parallel parsing and schema inference for format `JSONAsObject`. [#35592](https://github.com/ClickHouse/ClickHouse/pull/35592) ([Anton Popov](https://github.com/CurtizJ)).
-* Added a support for automatic schema inference to `s3Cluster` table function. Synced the signatures of `s3 ` and `s3Cluster`. [#35544](https://github.com/ClickHouse/ClickHouse/pull/35544) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* Added support for schema inference for `hdfsCluster`. [#35602](https://github.com/ClickHouse/ClickHouse/pull/35602) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* Add new setting `input_format_json_read_bools_as_numbers` that allows to infer and parse bools as numbers in JSON input formats. It's enabled by default. Suggested by @alexey-milovidov. [#35735](https://github.com/ClickHouse/ClickHouse/pull/35735) ([Kruglov Pavel](https://github.com/Avogar)).
-* Improve columns ordering in schema inference for formats TSKV and JSONEachRow, closes [#35640](https://github.com/ClickHouse/ClickHouse/issues/35640). Don't stop schema inference when reading empty row in schema inference for formats TSKV and JSONEachRow. [#35724](https://github.com/ClickHouse/ClickHouse/pull/35724) ([Kruglov Pavel](https://github.com/Avogar)).
-* Add settings `input_format_orc_case_insensitive_column_matching`, `input_format_arrow_case_insensitive_column_matching`, and `input_format_parquet_case_insensitive_column_matching` which allows ClickHouse to use case insensitive matching of columns while reading data from ORC, Arrow or Parquet files. [#35459](https://github.com/ClickHouse/ClickHouse/pull/35459) ([Antonio Andelic](https://github.com/antonio2368)).
-* Added `is_secure` column to `system.query_log` which denotes if the client is using a secure connection over TCP or HTTP. [#35705](https://github.com/ClickHouse/ClickHouse/pull/35705) ([Antonio Andelic](https://github.com/antonio2368)).
-* Now `kafka_num_consumers` can be bigger than amount of physical cores in case of low resource machine (less than 16 cores). [#35926](https://github.com/ClickHouse/ClickHouse/pull/35926) ([alesapin](https://github.com/alesapin)).
-* Add some basic metrics to monitor engine=Kafka tables. [#35916](https://github.com/ClickHouse/ClickHouse/pull/35916) ([filimonov](https://github.com/filimonov)).
-* Now it's not allowed to `ALTER TABLE ... RESET SETTING` for non-existing settings for MergeTree engines family. Fixes [#35816](https://github.com/ClickHouse/ClickHouse/issues/35816). [#35884](https://github.com/ClickHouse/ClickHouse/pull/35884) ([alesapin](https://github.com/alesapin)).
-* Now some `ALTER MODIFY COLUMN` queries for `Arrays` and `Nullable` types can be done at metadata level without mutations.

-
-#### Backward Incompatible Change
-
-* Make `arrayCompact` function behave as other higher-order functions: perform compaction not of lambda function results but on the original array. If you're using nontrivial lambda functions in arrayCompact you may restore old behaviour by wrapping `arrayCompact` arguments into `arrayMap`. Closes [#34010](https://github.com/ClickHouse/ClickHouse/issues/34010) [#18535](https://github.com/ClickHouse/ClickHouse/issues/18535) [#14778](https://github.com/ClickHouse/ClickHouse/issues/14778). [#34795](https://github.com/ClickHouse/ClickHouse/pull/34795) ([Alexandre Snarskii](https://github.com/snar)).
-* Change implementation specific behavior on overflow of function `toDatetime`. It will be saturated to the nearest min/max supported instant of datetime instead of wraparound. This change is highlighted as "backward incompatible" because someone may unintentionally rely on the old behavior. [#32898](https://github.com/ClickHouse/ClickHouse/pull/32898) ([HaiBo Li](https://github.com/marising)).
-* Make function `cast(value, 'IPv4')`, `cast(value, 'IPv6')` behave same as `toIPv4`, `toIPv6` functions. Changed behavior of incorrect IP address passed into functions `toIPv4`,` toIPv6`,  now if invalid IP address passes into this functions exception will be raised, before this function return default value. Added functions `IPv4StringToNumOrDefault`, `IPv4StringToNumOrNull`, `IPv6StringToNumOrDefault`, `IPv6StringOrNull` `toIPv4OrDefault`, `toIPv4OrNull`, `toIPv6OrDefault`, `toIPv6OrNull`. Functions `IPv4StringToNumOrDefault `, `toIPv4OrDefault `, `toIPv6OrDefault ` should be used if previous logic relied on `IPv4StringToNum`, `toIPv4`, `toIPv6` returning default value for invalid address. Added setting `cast_ipv4_ipv6_default_on_conversion_error`, if this setting enabled, then IP address conversion functions will behave as before. Closes [#22825](https://github.com/ClickHouse/ClickHouse/issues/22825). Closes [#5799](https://github.com/ClickHouse/ClickHouse/issues/5799). Closes [#35156](https://github.com/ClickHouse/ClickHouse/issues/35156). [#35240](https://github.com/ClickHouse/ClickHouse/pull/35240) ([Maksim Kita](https://github.com/kitaisreal)).
-
-#### New Feature
-
-* Support for caching data locally for remote filesystems. It can be enabled for `s3` disks. Closes [#28961](https://github.com/ClickHouse/ClickHouse/issues/28961). [#33717](https://github.com/ClickHouse/ClickHouse/pull/33717) ([Kseniia Sumarokova](https://github.com/kssenii)). In the meantime, we enabled the test suite on s3 filesystem and no more known issues exist, so it is started to be production ready.
-* Add new table function `hive`. It can be used as follows `hive('<hive metastore url>', '<hive database>', '<hive table name>', '<columns definition>', '<partition columns>')` for example `SELECT * FROM hive('thrift://hivetest:9083', 'test', 'demo', 'id Nullable(String), score Nullable(Int32), day Nullable(String)', 'day')`. [#34946](https://github.com/ClickHouse/ClickHouse/pull/34946) ([lgbo](https://github.com/lgbo-ustc)).
-* Support authentication of users connected via SSL by their X.509 certificate. [#31484](https://github.com/ClickHouse/ClickHouse/pull/31484) ([eungenue](https://github.com/eungenue)).
-* Support schema inference for inserting into table functions `file`/`hdfs`/`s3`/`url`. [#34732](https://github.com/ClickHouse/ClickHouse/pull/34732) ([Kruglov Pavel](https://github.com/Avogar)).
-* Now you can read `system.zookeeper` table without restrictions on path or using `like` expression. This reads can generate quite heavy load for zookeeper so to enable this ability you have to enable setting `allow_unrestricted_reads_from_keeper`. [#34609](https://github.com/ClickHouse/ClickHouse/pull/34609) ([Sergei Trifonov](https://github.com/serxa)).
-* Display CPU and memory metrics in clickhouse-local. Close [#34545](https://github.com/ClickHouse/ClickHouse/issues/34545). [#34605](https://github.com/ClickHouse/ClickHouse/pull/34605) ([李扬](https://github.com/taiyang-li)).
-* Implement `startsWith` and `endsWith` function for arrays, closes [#33982](https://github.com/ClickHouse/ClickHouse/issues/33982). [#34368](https://github.com/ClickHouse/ClickHouse/pull/34368) ([usurai](https://github.com/usurai)).
-* Add three functions for Map data type: 1. `mapReplace(map1, map2)` - replaces values for keys in map1 with the values of the corresponding keys in map2; adds keys from map2 that don't exist in map1. 2. `mapFilter` 3. `mapMap`. mapFilter and mapMap are higher order functions, accepting two arguments, the first argument is a lambda function with k, v pair as arguments, the second argument is a column of type Map. [#33698](https://github.com/ClickHouse/ClickHouse/pull/33698) ([hexiaoting](https://github.com/hexiaoting)).
-* Allow getting default user and password for clickhouse-client from the `CLICKHOUSE_USER` and `CLICKHOUSE_PASSWORD` environment variables. Close [#34538](https://github.com/ClickHouse/ClickHouse/issues/34538). [#34947](https://github.com/ClickHouse/ClickHouse/pull/34947) ([DR](https://github.com/freedomDR)).
-
-#### Experimental Feature
-
-* New data type `Object(<schema_format>)`, which supports storing of semi-structured data (for now JSON only). Data is written to such types as string. Then all paths are extracted according to format of semi-structured data and written as separate columns in most optimal types, that can store all their values. Those columns can be queried by names that match paths in source data. E.g `data.key1.key2` or with cast operator `data.key1.key2::Int64`.
-* Add `database_replicated_allow_only_replicated_engine` setting. When enabled, it only allowed to only create `Replicated` tables or tables with stateless engines in `Replicated` databases. [#35214](https://github.com/ClickHouse/ClickHouse/pull/35214) ([Nikolai Kochetov](https://github.com/KochetovNicolai)). Note that `Replicated` database is still an experimental feature.
-
-#### Performance Improvement
-
-* Improve performance of insertion into `MergeTree` tables by optimizing sorting. Up to 2x improvement is observed on realistic benchmarks. [#34750](https://github.com/ClickHouse/ClickHouse/pull/34750) ([Maksim Kita](https://github.com/kitaisreal)).
-* Columns pruning when reading Parquet, ORC and Arrow files from URL and S3. Closes [#34163](https://github.com/ClickHouse/ClickHouse/issues/34163). [#34849](https://github.com/ClickHouse/ClickHouse/pull/34849) ([Kseniia Sumarokova](https://github.com/kssenii)).
-* Columns pruning when reading Parquet, ORC and Arrow files from Hive. [#34954](https://github.com/ClickHouse/ClickHouse/pull/34954) ([lgbo](https://github.com/lgbo-ustc)).
-* A bunch of performance optimizations from a performance superhero. Improve performance of processing queries with large `IN` section. Improve performance of `direct` dictionary if its source is `ClickHouse`. Improve performance of `detectCharset `, `detectLanguageUnknown ` functions. [#34888](https://github.com/ClickHouse/ClickHouse/pull/34888) ([Maksim Kita](https://github.com/kitaisreal)).
-* Improve performance of `any` aggregate function by using more batching. [#34760](https://github.com/ClickHouse/ClickHouse/pull/34760) ([Raúl Marín](https://github.com/Algunenano)).
-* Multiple improvements for performance of `clickhouse-keeper`: less locking [#35010](https://github.com/ClickHouse/ClickHouse/pull/35010) ([zhanglistar](https://github.com/zhanglistar)), lower memory usage by streaming reading and writing of snapshot instead of full copy. [#34584](https://github.com/ClickHouse/ClickHouse/pull/34584) ([zhanglistar](https://github.com/zhanglistar)), optimizing compaction of log store in the RAFT implementation. [#34534](https://github.com/ClickHouse/ClickHouse/pull/34534) ([zhanglistar](https://github.com/zhanglistar)), versioning of the internal data structure [#34486](https://github.com/ClickHouse/ClickHouse/pull/34486) ([zhanglistar](https://github.com/zhanglistar)).

-* When large files were written with `s3` table function or table engine, the content type on the files was mistakenly set to `application/xml` due to a bug in the AWS SDK. This closes [#33964](https://github.com/ClickHouse/ClickHouse/issues/33964). [#34433](https://github.com/ClickHouse/ClickHouse/pull/34433) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-* Change restrictive row policies a bit to make them an easier alternative to permissive policies in easy cases. If for a particular table only restrictive policies exist (without permissive policies) users will be able to see some rows. Also `SHOW CREATE ROW POLICY` will always show `AS permissive` or `AS restrictive` in row policy's definition. [#34596](https://github.com/ClickHouse/ClickHouse/pull/34596) ([Vitaly Baranov](https://github.com/vitlibar)).
-* Improve schema inference with globs in File/S3/HDFS/URL engines. Try to use the next path for schema inference in case of error. [#34465](https://github.com/ClickHouse/ClickHouse/pull/34465) ([Kruglov Pavel](https://github.com/Avogar)).

-* A new settings called `allow_plaintext_password` and `allow_no_password` are added in server configuration which turn on/off authentication types that can be potentially insecure in some environments. They are allowed by default. [#34738](https://github.com/ClickHouse/ClickHouse/pull/34738) ([Heena Bansal](https://github.com/HeenaBansal2009)).
-* Support for `DateTime64` data type in `Arrow` format, closes [#8280](https://github.com/ClickHouse/ClickHouse/issues/8280) and closes [#28574](https://github.com/ClickHouse/ClickHouse/issues/28574). [#34561](https://github.com/ClickHouse/ClickHouse/pull/34561) ([李扬](https://github.com/taiyang-li)).

-* Add `distributed_depth` to query log. It is like a more detailed variant of `is_initial_query` [#35207](https://github.com/ClickHouse/ClickHouse/pull/35207) ([李扬](https://github.com/taiyang-li)).
-* Respect `remote_url_allow_hosts` for `MySQL` and `PostgreSQL` table functions. [#35191](https://github.com/ClickHouse/ClickHouse/pull/35191) ([Heena Bansal](https://github.com/HeenaBansal2009)).
-* Added `disk_name` field to `system.part_log`. [#35178](https://github.com/ClickHouse/ClickHouse/pull/35178) ([Artyom Yurkov](https://github.com/Varinara)).
-* Do not retry non-rertiable errors when querying remote URLs. Closes [#35161](https://github.com/ClickHouse/ClickHouse/issues/35161). [#35172](https://github.com/ClickHouse/ClickHouse/pull/35172) ([Kseniia Sumarokova](https://github.com/kssenii)).

-* More precise memory tracking during `INSERT` into `Buffer` with `AggregateFunction`. [#35072](https://github.com/ClickHouse/ClickHouse/pull/35072) ([Azat Khuzhin](https://github.com/azat)).
-* Avoid division by zero in Query Profiler if Linux kernel has a bug. Closes [#34787](https://github.com/ClickHouse/ClickHouse/issues/34787). [#35032](https://github.com/ClickHouse/ClickHouse/pull/35032) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-* Add more sanity checks for keeper configuration: now mixing of localhost and non-local servers is not allowed, also add checks for same value of internal raft port and keeper client port. [#35004](https://github.com/ClickHouse/ClickHouse/pull/35004) ([alesapin](https://github.com/alesapin)).
-* Currently, if the user changes the settings of the system tables there will be tons of logs and ClickHouse will rename the tables every minute. This fixes [#34929](https://github.com/ClickHouse/ClickHouse/issues/34929). [#34949](https://github.com/ClickHouse/ClickHouse/pull/34949) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).

-* In previous versions the progress bar in clickhouse-client can jump forward near 50% for no reason. This closes [#34324](https://github.com/ClickHouse/ClickHouse/issues/34324). [#34801](https://github.com/ClickHouse/ClickHouse/pull/34801) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-* Now `ALTER TABLE DROP COLUMN columnX` queries for `MergeTree` table engines will work instantly when `columnX` is an `ALIAS` column. Fixes [#34660](https://github.com/ClickHouse/ClickHouse/issues/34660). [#34786](https://github.com/ClickHouse/ClickHouse/pull/34786) ([alesapin](https://github.com/alesapin)).
-* Show hints when user mistyped the name of a data skipping index. Closes [#29698](https://github.com/ClickHouse/ClickHouse/issues/29698). [#34764](https://github.com/ClickHouse/ClickHouse/pull/34764) ([flynn](https://github.com/ucasfl)).

-* Extract schema only once on table creation and prevent reading from local files/external sources to extract schema on each server startup. [#34684](https://github.com/ClickHouse/ClickHouse/pull/34684) ([Kruglov Pavel](https://github.com/Avogar)).
-* Allow specifying argument names for executable UDFs. This is necessary for formats where argument name is part of serialization, like `Native`, `JSONEachRow`. Closes [#34604](https://github.com/ClickHouse/ClickHouse/issues/34604). [#34653](https://github.com/ClickHouse/ClickHouse/pull/34653) ([Maksim Kita](https://github.com/kitaisreal)).
-* `MaterializedMySQL` (experimental feature) now supports `materialized_mysql_tables_list` (a comma-separated list of MySQL database tables, which will be replicated by the MaterializedMySQL database engine. Default value: empty list — means all the tables will be replicated), mentioned at [#32977](https://github.com/ClickHouse/ClickHouse/issues/32977).

-
-#### Build/Testing/Packaging Improvement
-
-* Package repository is migrated to JFrog Artifactory (**Mikhail f. Shiryaev**).
-* Randomize some settings in functional tests, so more possible combinations of settings will be tested. This is yet another fuzzing method to ensure better test coverage. This closes [#32268](https://github.com/ClickHouse/ClickHouse/issues/32268). [#34092](https://github.com/ClickHouse/ClickHouse/pull/34092) ([Kruglov Pavel](https://github.com/Avogar)).
-* Drop PVS-Studio from our CI. [#34680](https://github.com/ClickHouse/ClickHouse/pull/34680) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).

-* Limit DWARF version for debug info by 4 max, because our internal stack symbolizer cannot parse DWARF version 5. This makes sense if you compile ClickHouse with clang-15. [#34777](https://github.com/ClickHouse/ClickHouse/pull/34777) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
-* Remove `clickhouse-test` debian package as unneeded complication. CI use tests from repository and standalone testing via deb package is no longer supported. [#34606](https://github.com/ClickHouse/ClickHouse/pull/34606) ([Ilya Yatsishin](https://github.com/qoega)).
-
-#### Bug Fix (user-visible misbehaviour in official stable or prestable release)
-
-* A fix for HDFS integration: When the inner buffer size is too small, NEED_MORE_INPUT in `HadoopSnappyDecoder` will run multi times (>=3) for one compressed block.

[#34696](https://github.com/ClickHouse/ClickHouse/pull/34696) ([Maksim Kita](https://github.com/kitaisreal)).
-* Fix `allow_experimental_projection_optimization` with `enable_global_with_statement` (before it may lead to `Stack size too large` error in case of multiple expressions in `WITH` clause, and also it executes scalar subqueries again and again, so not it will be more optimal). [#34650](https://github.com/ClickHouse/ClickHouse/pull/34650) ([Azat Khuzhin](https://github.com/azat)).
-* Stop to select part for mutate when the other replica has already updated the transaction log for `ReplatedMergeTree` engine. [#34633](https://github.com/ClickHouse/ClickHouse/pull/34633) ([Jianmei Zhang](https://github.com/zhangjmruc)).

-### <a id="222"></a> ClickHouse release v22.2, 2022-02-17
-
-#### Upgrade Notes
-
-* Applying data skipping indexes for queries with FINAL may produce incorrect result. In this release we disabled data skipping indexes by default for queries with FINAL (a new setting `use_skip_indexes_if_final` is introduced and disabled by default). [#34243](https://github.com/ClickHouse/ClickHouse/pull/34243) ([Azat Khuzhin](https://github.com/azat)).
-
-#### New Feature
-
-* Projections are production ready. Set `allow_experimental_projection_optimization` by default and deprecate this setting. [#34456](https://github.com/ClickHouse/ClickHouse/pull/34456) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
-* An option to create a new files on insert for `File`/`S3`/`HDFS` engines. Allow to overwrite a file in `HDFS`. Throw an exception in attempt to overwrite a file in `S3` by default. Throw an exception in attempt to append data to file in formats that have a suffix (and thus don't support appends, like `Parquet`, `ORC`). Closes [#31640](https://github.com/ClickHouse/ClickHouse/issues/31640) Closes [#31622](https://github.com/ClickHouse/ClickHouse/issues/31622) Closes [#23862](https://github.com/ClickHouse/ClickHouse/issues/23862) Closes [#15022](https://github.com/ClickHouse/ClickHouse/issues/15022) Closes [#16674](https://github.com/ClickHouse/ClickHouse/issues/16674). [#33302](https://github.com/ClickHouse/ClickHouse/pull/33302) ([Kruglov Pavel](https://github.com/Avogar)).
-* Add a setting that allows a user to provide own deduplication semantic in `MergeTree`/`ReplicatedMergeTree` If provided, it's used instead of data digest to generate block ID. So, for example, by providing a unique value for the setting in each INSERT statement, the user can avoid the same inserted data being deduplicated. This closes: [#7461](https://github.com/ClickHouse/ClickHouse/issues/7461). [#32304](https://github.com/ClickHouse/ClickHouse/pull/32304) ([Igor Nikonov](https://github.com/devcrafter)).
-* Add support of `DEFAULT` keyword for INSERT statements. Closes [#6331](https://github.com/ClickHouse/ClickHouse/issues/6331). [#33141](https://github.com/ClickHouse/ClickHouse/pull/33141) ([Andrii Buriachevskyi](https://github.com/1over)).
-* `EPHEMERAL` column specifier is added to `CREATE TABLE` query. Closes [#9436](https://github.com/ClickHouse/ClickHouse/issues/9436). [#34424](https://github.com/ClickHouse/ClickHouse/pull/34424) ([yakov-olkhovskiy](https://github.com/yakov-olkhovskiy)).
-* Support `IF EXISTS` clause for `TTL expr TO [DISK|VOLUME] [IF EXISTS] 'xxx'` feature. Parts will be moved to disk or volume only if it exists on replica, so `MOVE TTL` rules will be able to behave differently on replicas according to the existing storage policies. Resolves [#34455](https://github.com/ClickHouse/ClickHouse/issues/34455). [#34504](https://github.com/ClickHouse/ClickHouse/pull/34504) ([Anton Popov](https://github.com/CurtizJ)).

[#15765](https://github.com/ClickHouse/ClickHouse/pull/15765) ([johnskopis](https://github.com/johnskopis)). [#31257](https://github.com/ClickHouse/ClickHouse/pull/31257) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
-* Now ReplicatedMergeTree can recover data when some of its disks are broken. [#13544](https://github.com/ClickHouse/ClickHouse/pull/13544) ([Amos Bird](https://github.com/amosbird)).
-* Fault-tolerant connections in clickhouse-client: `clickhouse-client ... --host host1 --host host2 --port port2 --host host3 --port port --host host4`. [#34490](https://github.com/ClickHouse/ClickHouse/pull/34490) ([Kruglov Pavel](https://github.com/Avogar)). [#33824](https://github.com/ClickHouse/ClickHouse/pull/33824) ([Filippov Denis](https://github.com/DF5HSE)).

-* Add memory overcommit to `MemoryTracker`. Added `guaranteed` settings for memory limits which represent soft memory limits. In case when hard memory limit is reached, `MemoryTracker` tries to cancel the most overcommited query. New setting `memory_usage_overcommit_max_wait_microseconds` specifies how long queries may wait another query to stop. Closes [#28375](https://github.com/ClickHouse/ClickHouse/issues/28375). [#31182](https://github.com/ClickHouse/ClickHouse/pull/31182) ([Dmitry Novik](https://github.com/novikd)).

This fixes [#34273](https://github.com/ClickHouse/ClickHouse/issues/34273). [#34305](https://github.com/ClickHouse/ClickHouse/pull/34305) ([Amos Bird](https://github.com/amosbird)).
-
-#### Performance Improvement
-
-* Support `optimize_read_in_order` if prefix of sorting key is already sorted. E.g. if we have sorting key `ORDER BY (a, b)` in table and query with `WHERE a = const ORDER BY b` clauses, now it will be applied reading in order of sorting key instead of full sort. [#32748](https://github.com/ClickHouse/ClickHouse/pull/32748) ([Anton Popov](https://github.com/CurtizJ)).
-* Improve performance of partitioned insert into table functions `URL`, `S3`, `File`, `HDFS`. Closes [#34348](https://github.com/ClickHouse/ClickHouse/issues/34348). [#34510](https://github.com/ClickHouse/ClickHouse/pull/34510) ([Maksim Kita](https://github.com/kitaisreal)).

-### <a id="221"></a> ClickHouse release v22.1, 2022-01-18
-
-#### Upgrade Notes
-
-* The functions `left` and `right` were previously implemented in parser and now full-featured. Distributed queries with `left` or `right` functions without aliases may throw exception if cluster contains different versions of clickhouse-server. If you are upgrading your cluster and encounter this error, you should finish upgrading your cluster to ensure all nodes have the same version. Also you can add aliases (`AS something`) to the columns in your queries to avoid this issue. [#33407](https://github.com/ClickHouse/ClickHouse/pull/33407) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* Resource usage by scalar subqueries is fully accounted since this version. With this change, rows read in scalar subqueries are now reported in the query_log. If the scalar subquery is cached (repeated or called for several rows) the rows read are only counted once. This change allows KILLing queries and reporting progress while they are executing scalar subqueries. [#32271](https://github.com/ClickHouse/ClickHouse/pull/32271) ([Raúl Marín](https://github.com/Algunenano)).
-
-#### New Feature
-
-* Implement data schema inference for input formats. Allow to skip structure (or write just `auto`) in table functions `file`, `url`, `s3`, `hdfs` and in parameters of `clickhouse-local` . Allow to skip structure in create query for table engines `File`, `HDFS`, `S3`, `URL`, `Merge`, `Buffer`, `Distributed` and `ReplicatedMergeTree` (if we add new replicas). [#32455](https://github.com/ClickHouse/ClickHouse/pull/32455) ([Kruglov Pavel](https://github.com/Avogar)).
-* Detect format by file extension in `file`/`hdfs`/`s3`/`url` table functions and `HDFS`/`S3`/`URL` table engines and also for `SELECT INTO OUTFILE` and `INSERT FROM INFILE` [#33565](https://github.com/ClickHouse/ClickHouse/pull/33565) ([Kruglov Pavel](https://github.com/Avogar)). Close [#30918](https://github.com/ClickHouse/ClickHouse/issues/30918). [#33443](https://github.com/ClickHouse/ClickHouse/pull/33443) ([OnePiece](https://github.com/zhongyuankai)).

-* Automatic cluster discovery via Zoo/Keeper. It allows to add replicas to the cluster without changing configuration on every server. [#31442](https://github.com/ClickHouse/ClickHouse/pull/31442) ([vdimir](https://github.com/vdimir)).
-* Implement hive table engine to access apache hive from clickhouse. This implements: [#29245](https://github.com/ClickHouse/ClickHouse/issues/29245). [#31104](https://github.com/ClickHouse/ClickHouse/pull/31104) ([taiyang-li](https://github.com/taiyang-li)).
-* Add aggregate functions `cramersV`, `cramersVBiasCorrected`, `theilsU` and `contingency`. These functions calculate dependency (measure of association) between categorical values. All these functions are using cross-tab (histogram on pairs) for implementation. You can imagine it like a correlation coefficient but for any discrete values (not necessary numbers). [#33366](https://github.com/ClickHouse/ClickHouse/pull/33366) ([alexey-milovidov](https://github.com/alexey-milovidov)). Initial implementation by [Vanyok-All-is-OK](https://github.com/Vanyok-All-is-OK) and [antikvist](https://github.com/antikvist).
-* Added table function `hdfsCluster` which allows processing files from HDFS in parallel from many nodes in a specified cluster, similarly to `s3Cluster`. [#32400](https://github.com/ClickHouse/ClickHouse/pull/32400) ([Zhichang Yu](https://github.com/yuzhichang)).
-* Adding support for disks backed by Azure Blob Storage, in a similar way it has been done for disks backed by AWS S3. [#31505](https://github.com/ClickHouse/ClickHouse/pull/31505) ([Jakub Kuklis](https://github.com/jkuklis)).

-* Added `left`, `right`, `leftUTF8`, `rightUTF8` functions. Fix error in implementation of `substringUTF8` function with negative offset (offset from the end of string). [#33407](https://github.com/ClickHouse/ClickHouse/pull/33407) ([alexey-milovidov](https://github.com/alexey-milovidov)).
-* Add new functions for `H3` coordinate system: `h3HexAreaKm2`, `h3CellAreaM2`, `h3CellAreaRads2`. [#33479](https://github.com/ClickHouse/ClickHouse/pull/33479) ([Bharat Nallan](https://github.com/bharatnc)).
-* Add `MONTHNAME` function. [#33436](https://github.com/ClickHouse/ClickHouse/pull/33436) ([usurai](https://github.com/usurai)).
-* Added function `arrayLast`. Closes [#33390](https://github.com/ClickHouse/ClickHouse/issues/33390). [#33415](https://github.com/ClickHouse/ClickHouse/pull/33415) Added function `arrayLastIndex`. [#33465](https://github.com/ClickHouse/ClickHouse/pull/33465) ([Maksim Kita](https://github.com/kitaisreal)).
-* Add function `decodeURLFormComponent` slightly different to `decodeURLComponent`. Close [#10298](https://github.com/ClickHouse/ClickHouse/issues/10298). [#33451](https://github.com/ClickHouse/ClickHouse/pull/33451) ([SuperDJY](https://github.com/cmsxbc)).
-* Allow to split `GraphiteMergeTree` rollup rules for plain/tagged metrics (optional rule_type field). [#33494](https://github.com/ClickHouse/ClickHouse/pull/33494) ([Michail Safronov](https://github.com/msaf1980)).
-
-
-#### Performance Improvement
-
-* Support moving conditions to `PREWHERE` (setting `optimize_move_to_prewhere`) for tables of `Merge` engine if its all underlying tables supports `PREWHERE`. [#33300](https://github.com/ClickHouse/ClickHouse/pull/33300) ([Anton Popov](https://github.com/CurtizJ)).
-* More efficient handling of globs for URL storage. Now you can easily query million URLs in parallel with retries. Closes [#32866](https://github.com/ClickHouse/ClickHouse/issues/32866). [#32907](https://github.com/ClickHouse/ClickHouse/pull/32907) ([Kseniia Sumarokova](https://github.com/kssenii)).

-#### 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). [#29279](https://github.com/ClickHouse/ClickHouse/pull/29279) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
-* Implemented sparse serialization. It can reduce usage of disk space and improve performance of some queries for columns, which contain a lot of default (zero) values. It can be enabled by setting `ratio_for_sparse_serialization`. Sparse serialization will be chosen dynamically for column, if it has ratio of number of default values to number of all values above that threshold. Serialization (default or sparse) will be fixed for every column in part, but may varies between parts. [#22535](https://github.com/ClickHouse/ClickHouse/pull/22535) ([Anton Popov](https://github.com/CurtizJ)).

-* Change ZooKeeper path for zero-copy marks for shared data. Note that "zero-copy replication" is non-production feature (in early stages of development) that you shouldn't use anyway. But in case if you have used it, let you keep in mind this change. [#32061](https://github.com/ClickHouse/ClickHouse/pull/32061) ([ianton-ru](https://github.com/ianton-ru)).
-* Events clause support for WINDOW VIEW watch query. [#32607](https://github.com/ClickHouse/ClickHouse/pull/32607) ([vxider](https://github.com/Vxider)).
-* Fix ACL with explicit digit hash in `clickhouse-keeper`: now the behavior consistent with ZooKeeper and generated digest is always accepted. [#33249](https://github.com/ClickHouse/ClickHouse/pull/33249) ([小路](https://github.com/nicelulu)). [#33246](https://github.com/ClickHouse/ClickHouse/pull/33246).

+* Don't execute and/or/if/multiIf on a LowCardinality dictionary, so the result type cannot be LowCardinality. It could lead to the error `Illegal column ColumnLowCardinality` in some cases. Fixes [#43603](https://github.com/ClickHouse/ClickHouse/issues/43603). [#44469](https://github.com/ClickHouse/ClickHouse/pull/44469) ([Kruglov Pavel](https://github.com/Avogar)).

+* Projections do not work in presence of WITH ROLLUP, WITH CUBE and WITH TOTALS. In previous versions, a query produced an exception instead of skipping the usage of projections. This closes [#44614](https://github.com/ClickHouse/ClickHouse/issues/44614). This closes [#42772](https://github.com/ClickHouse/ClickHouse/issues/42772). [#44615](https://github.com/ClickHouse/ClickHouse/pull/44615) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

+* Fix fsync for fetches (`min_compressed_bytes_to_fsync_after_fetch`)/small files (ttl.txt, columns.txt) in mutations (`min_rows_to_fsync_after_merge`/`min_compressed_bytes_to_fsync_after_merge`). [#44781](https://github.com/ClickHouse/ClickHouse/pull/44781) ([Azat Khuzhin](https://github.com/azat)).
+* A rare race condition was possible when querying the `system.parts` or `system.parts_columns` tables in the presence of parts being moved between disks. Introduced in [#41145](https://github.com/ClickHouse/ClickHouse/issues/41145). [#44809](https://github.com/ClickHouse/ClickHouse/pull/44809) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Fix the error `Context has expired` which could appear with enabled projections optimization. Can be reproduced for queries with specific functions, like `dictHas/dictGet` which use context in runtime. Fixes [#44844](https://github.com/ClickHouse/ClickHouse/issues/44844). [#44850](https://github.com/ClickHouse/ClickHouse/pull/44850) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

+* Delay for INSERT can be calculated incorrectly, which can lead to always using `max_delay_to_insert` setting as delay instead of a correct value. Using simple formula `max_delay_to_insert * (parts_over_threshold/max_allowed_parts_over_threshold)` i.e. delay grows proportionally to parts over threshold. Closes [#44902](https://github.com/ClickHouse/ClickHouse/issues/44902). [#44954](https://github.com/ClickHouse/ClickHouse/pull/44954) ([Igor Nikonov](https://github.com/devcrafter)).

 ## Public Disclosure Timing
 
-A public disclosure date is negotiated by the ClickHouse maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to 90 days. For a vulnerability with a straightforward mitigation, we expect report date to disclosure date to be on the order of 7 days.
