 The default is slightly more than `max_block_size`. The reason for this is because certain table engines (`*MergeTree`) form a data part on the disk for each inserted block, which is a fairly large entity. Similarly, `*MergeTree` tables sort data during insertion and a large enough block size allow sorting more data in RAM.

+# SimpleAggregateFunction(name, types\_of\_arguments…) {#data-type-simpleaggregatefunction}
+
+`SimpleAggregateFunction` data type stores current value of the aggregate function, and does not store its full state as [`AggregateFunction`](aggregatefunction.md) does. This optimization can be applied to functions for which the following property holds: the result of applying a function `f` to a row set `S1 UNION ALL S2` can be obtained by applying `f` to parts of the row set separately, and then again applying `f` to the results: `f(S1 UNION ALL S2) = f(f(S1) UNION ALL f(S2))`. This property guarantees that partial aggregation results are enough to compute the combined one, so we don't have to store and process any extra data.
+
+The following aggregate functions are supported:
+
+- [`any`](../../sql_reference/aggregate_functions/reference.md#agg_function-any)
+- [`anyLast`](../../sql_reference/aggregate_functions/reference.md#anylastx)
+- [`min`](../../sql_reference/aggregate_functions/reference.md#agg_function-min)
+- [`max`](../../sql_reference/aggregate_functions/reference.md#agg_function-max)
+- [`sum`](../../sql_reference/aggregate_functions/reference.md#agg_function-sum)
+- [`groupBitAnd`](../../sql_reference/aggregate_functions/reference.md#groupbitand)
+- [`groupBitOr`](../../sql_reference/aggregate_functions/reference.md#groupbitor)
+- [`groupBitXor`](../../sql_reference/aggregate_functions/reference.md#groupbitxor)
+
+
+Values of the `SimpleAggregateFunction(func, Type)` look and stored the same way as `Type`, so you do not need to apply functions with `-Merge`/`-State` suffixes. `SimpleAggregateFunction` has better performance than `AggregateFunction` with same aggregation function.
+
+**Parameters**
+
+- Name of the aggregate function.
+- Types of the aggregate function arguments.
+
+**Example**
+
+``` sql
+CREATE TABLE t
+(
+    column1 SimpleAggregateFunction(sum, UInt64),
+    column2 SimpleAggregateFunction(any, String)
+) ENGINE = ...

Replication will continue after all replicas of the cluster are updated.

-## ClickHouse release v20.3
-
-### ClickHouse release v20.3.4.10, 2020-03-20
-
-#### Bug Fix
-* This release also contains all bug fixes from 20.1.8.41
-* Fix missing `rows_before_limit_at_least` for queries over http (with processors pipeline). This fixes [#9730](https://github.com/ClickHouse/ClickHouse/issues/9730). [#9757](https://github.com/ClickHouse/ClickHouse/pull/9757) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
-
-
-### ClickHouse release v20.3.3.6, 2020-03-17
-
-#### Bug Fix
-* This release also contains all bug fixes from 20.1.7.38
-* Fix bug in a replication that doesn't allow replication to work if the user has executed mutations on the previous version. This fixes [#9645](https://github.com/ClickHouse/ClickHouse/issues/9645). [#9652](https://github.com/ClickHouse/ClickHouse/pull/9652) ([alesapin](https://github.com/alesapin)). It makes version 20.3 backward compatible again.
-* Add setting `use_compact_format_in_distributed_parts_names` which allows to write files for `INSERT` queries into `Distributed` table with more compact format. This fixes [#9647](https://github.com/ClickHouse/ClickHouse/issues/9647). [#9653](https://github.com/ClickHouse/ClickHouse/pull/9653) ([alesapin](https://github.com/alesapin)). It makes version 20.3 backward compatible again.
-
-### ClickHouse release v20.3.2.1, 2020-03-12
-
-#### Backward Incompatible Change
-
-* Fixed the issue `file name too long` when sending data for `Distributed` tables for a large number of replicas. Fixed the issue that replica credentials were exposed in the server log. The format of directory name on disk was changed to `[shard{shard_index}[_replica{replica_index}]]`. [#8911](https://github.com/ClickHouse/ClickHouse/pull/8911) ([Mikhail Korotov](https://github.com/millb)) After you upgrade to the new version, you will not be able to downgrade without manual intervention, because old server version does not recognize the new directory format. If you want to downgrade, you have to manually rename the corresponding directories to the old format. This change is relevant only if you have used asynchronous `INSERT`s to `Distributed` tables. In the version 20.3.3 we will introduce a setting that will allow you to enable the new format gradually.
-* Changed the format of replication log entries for mutation commands. You have to wait for old mutations to process before installing the new version.
-* Implement simple memory profiler that dumps stacktraces to `system.trace_log` every N bytes over soft allocation limit [#8765](https://github.com/ClickHouse/ClickHouse/pull/8765) ([Ivan](https://github.com/abyss7)) [#9472](https://github.com/ClickHouse/ClickHouse/pull/9472) ([alexey-milovidov](https://github.com/alexey-milovidov)) The column of `system.trace_log` was renamed from `timer_type` to `trace_type`. This will require changes in third-party performance analysis and flamegraph processing tools.
-* Use OS thread id everywhere instead of internal thread number. This fixes [#7477](https://github.com/ClickHouse/ClickHouse/issues/7477) Old `clickhouse-client` cannot receive logs that are send from the server when the setting `send_logs_level` is enabled, because the names and types of the structured log messages were changed. On the other hand, different server versions can send logs with different types to each other. When you don't use the `send_logs_level` setting, you should not care. [#8954](https://github.com/ClickHouse/ClickHouse/pull/8954) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Remove `indexHint` function [#9542](https://github.com/ClickHouse/ClickHouse/pull/9542) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Remove `findClusterIndex`, `findClusterValue` functions. This fixes [#8641](https://github.com/ClickHouse/ClickHouse/issues/8641). If you were using these functions, send an email to `clickhouse-feedback@yandex-team.com` [#9543](https://github.com/ClickHouse/ClickHouse/pull/9543) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Now it's not allowed to create columns or add columns with `SELECT` subquery as default expression. [#9481](https://github.com/ClickHouse/ClickHouse/pull/9481) ([alesapin](https://github.com/alesapin))
-* Require aliases for subqueries in JOIN. [#9274](https://github.com/ClickHouse/ClickHouse/pull/9274) ([Artem Zuikov](https://github.com/4ertus2))
-* Improved `ALTER MODIFY/ADD` queries logic. Now you cannot `ADD` column without type, `MODIFY` default expression doesn't change type of column and `MODIFY` type doesn't loose default expression value. Fixes [#8669](https://github.com/ClickHouse/ClickHouse/issues/8669). [#9227](https://github.com/ClickHouse/ClickHouse/pull/9227) ([alesapin](https://github.com/alesapin))
-* Require server to be restarted to apply the changes in logging configuration. This is a temporary workaround to avoid the bug where the server logs to a deleted log file (see [#8696](https://github.com/ClickHouse/ClickHouse/issues/8696)). [#8707](https://github.com/ClickHouse/ClickHouse/pull/8707) ([Alexander Kuzmenkov](https://github.com/akuzm))
-* The setting `experimental_use_processors` is enabled by default. This setting enables usage of the new query pipeline. This is internal refactoring and we expect no visible changes. If you will see any issues, set it to back zero. [#8768](https://github.com/ClickHouse/ClickHouse/pull/8768) ([alexey-milovidov](https://github.com/alexey-milovidov))
-
-#### New Feature
-* Add `Avro` and `AvroConfluent` input/output formats [#8571](https://github.com/ClickHouse/ClickHouse/pull/8571) ([Andrew Onyshchuk](https://github.com/oandrew)) [#8957](https://github.com/ClickHouse/ClickHouse/pull/8957) ([Andrew Onyshchuk](https://github.com/oandrew)) [#8717](https://github.com/ClickHouse/ClickHouse/pull/8717) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Multi-threaded and non-blocking updates of expired keys in `cache` dictionaries (with optional permission to read old ones). [#8303](https://github.com/ClickHouse/ClickHouse/pull/8303) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov))
-* Add query `ALTER ... MATERIALIZE TTL`. It runs mutation that forces to remove expired data by TTL and recalculates meta-information about TTL in all parts. [#8775](https://github.com/ClickHouse/ClickHouse/pull/8775) ([Anton Popov](https://github.com/CurtizJ))
-* Switch from HashJoin to MergeJoin (on disk) if needed [#9082](https://github.com/ClickHouse/ClickHouse/pull/9082) ([Artem Zuikov](https://github.com/4ertus2))
-* Added `MOVE PARTITION` command for `ALTER TABLE` [#4729](https://github.com/ClickHouse/ClickHouse/issues/4729) [#6168](https://github.com/ClickHouse/ClickHouse/pull/6168) ([Guillaume Tassery](https://github.com/YiuRULE))
-* Reloading storage configuration from configuration file on the fly. [#8594](https://github.com/ClickHouse/ClickHouse/pull/8594) ([Vladimir Chebotarev](https://github.com/excitoon))
-* Allowed to change `storage_policy` to not less rich one. [#8107](https://github.com/ClickHouse/ClickHouse/pull/8107) ([Vladimir Chebotarev](https://github.com/excitoon))
-* Added support for globs/wildcards for S3 storage and table function. [#8851](https://github.com/ClickHouse/ClickHouse/pull/8851) ([Vladimir Chebotarev](https://github.com/excitoon))
-* Implement `bitAnd`, `bitOr`, `bitXor`, `bitNot` for `FixedString(N)` datatype. [#9091](https://github.com/ClickHouse/ClickHouse/pull/9091) ([Guillaume Tassery](https://github.com/YiuRULE))
-* Added function `bitCount`. This fixes [#8702](https://github.com/ClickHouse/ClickHouse/issues/8702). [#8708](https://github.com/ClickHouse/ClickHouse/pull/8708) ([alexey-milovidov](https://github.com/alexey-milovidov)) [#8749](https://github.com/ClickHouse/ClickHouse/pull/8749) ([ikopylov](https://github.com/ikopylov))
-* Add `generateRandom` table function to generate random rows with given schema. Allows to populate arbitrary test table with data. [#8994](https://github.com/ClickHouse/ClickHouse/pull/8994) ([Ilya Yatsishin](https://github.com/qoega))
-* `JSONEachRowFormat`: support special case when objects enclosed in top-level array. [#8860](https://github.com/ClickHouse/ClickHouse/pull/8860) ([Kruglov Pavel](https://github.com/Avogar))
-* Now it's possible to create a column with `DEFAULT` expression which depends on a column with default `ALIAS` expression. [#9489](https://github.com/ClickHouse/ClickHouse/pull/9489) ([alesapin](https://github.com/alesapin))
-* Allow to specify `--limit` more than the source data size in `clickhouse-obfuscator`. The data will repeat itself with different random seed. [#9155](https://github.com/ClickHouse/ClickHouse/pull/9155) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Added `groupArraySample` function (similar to `groupArray`) with reservior sampling algorithm. [#8286](https://github.com/ClickHouse/ClickHouse/pull/8286) ([Amos Bird](https://github.com/amosbird))
-* Now you can monitor the size of update queue in `cache`/`complex_key_cache` dictionaries via system metrics. [#9413](https://github.com/ClickHouse/ClickHouse/pull/9413) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov))
-* Allow to use CRLF as a line separator in CSV output format with setting `output_format_csv_crlf_end_of_line` is set to 1 [#8934](https://github.com/ClickHouse/ClickHouse/pull/8934) [#8935](https://github.com/ClickHouse/ClickHouse/pull/8935) [#8963](https://github.com/ClickHouse/ClickHouse/pull/8963) ([Mikhail Korotov](https://github.com/millb))
-* Implement more functions of the [H3](https://github.com/uber/h3) API: `h3GetBaseCell`, `h3HexAreaM2`, `h3IndexesAreNeighbors`, `h3ToChildren`, `h3ToString` and `stringToH3` [#8938](https://github.com/ClickHouse/ClickHouse/pull/8938) ([Nico Mandery](https://github.com/nmandery))
-* New setting introduced: `max_parser_depth` to control maximum stack size and allow large complex queries. This fixes [#6681](https://github.com/ClickHouse/ClickHouse/issues/6681) and [#7668](https://github.com/ClickHouse/ClickHouse/issues/7668). [#8647](https://github.com/ClickHouse/ClickHouse/pull/8647) ([Maxim Smirnov](https://github.com/qMBQx8GH))
-* Add a setting `force_optimize_skip_unused_shards` setting to throw if skipping of unused shards is not possible [#8805](https://github.com/ClickHouse/ClickHouse/pull/8805) ([Azat Khuzhin](https://github.com/azat))
-* Allow to configure multiple disks/volumes for storing data for send in `Distributed` engine [#8756](https://github.com/ClickHouse/ClickHouse/pull/8756) ([Azat Khuzhin](https://github.com/azat))
-* Support storage policy (`<tmp_policy>`) for storing temporary data. [#8750](https://github.com/ClickHouse/ClickHouse/pull/8750) ([Azat Khuzhin](https://github.com/azat))
-* Added `X-ClickHouse-Exception-Code` HTTP header that is set if exception was thrown before sending data. This implements [#4971](https://github.com/ClickHouse/ClickHouse/issues/4971). [#8786](https://github.com/ClickHouse/ClickHouse/pull/8786) ([Mikhail Korotov](https://github.com/millb))
-* Added function `ifNotFinite`. It is just a syntactic sugar: `ifNotFinite(x, y) = isFinite(x) ? x : y`. [#8710](https://github.com/ClickHouse/ClickHouse/pull/8710) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Added `last_successful_update_time` column in `system.dictionaries` table [#9394](https://github.com/ClickHouse/ClickHouse/pull/9394) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov))
-* Add `blockSerializedSize` function (size on disk without compression) [#8952](https://github.com/ClickHouse/ClickHouse/pull/8952) ([Azat Khuzhin](https://github.com/azat))
-* Add function `moduloOrZero` [#9358](https://github.com/ClickHouse/ClickHouse/pull/9358) ([hcz](https://github.com/hczhcz))
-* Added system tables `system.zeros` and `system.zeros_mt` as well as tale functions `zeros()` and `zeros_mt()`. Tables (and table functions) contain single column with name `zero` and type `UInt8`. This column contains zeros. It is needed for test purposes as the fastest method to generate many rows. This fixes [#6604](https://github.com/ClickHouse/ClickHouse/issues/6604) [#9593](https://github.com/ClickHouse/ClickHouse/pull/9593) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
-
-#### Experimental Feature
-* Add new compact format of parts in `MergeTree`-family tables in which all columns are stored in one file. It helps to increase performance of small and frequent inserts. The old format (one file per column) is now called wide. Data storing format is controlled by settings `min_bytes_for_wide_part` and `min_rows_for_wide_part`. [#8290](https://github.com/ClickHouse/ClickHouse/pull/8290) ([Anton Popov](https://github.com/CurtizJ))
-* Support for S3 storage for `Log`, `TinyLog` and `StripeLog` tables. [#8862](https://github.com/ClickHouse/ClickHouse/pull/8862) ([Pavel Kovalenko](https://github.com/Jokser))
-
-#### Bug Fix

-* Remove outdated partition when we shutdown the server or DETACH/ATTACH a table. [#8602](https://github.com/ClickHouse/ClickHouse/pull/8602) ([Guillaume Tassery](https://github.com/YiuRULE))
-* For how the default disk calculates the free space from `data` subdirectory. Fixed the issue when the amount of free space is not calculated correctly if the `data` directory is mounted to a separate device (rare case). This fixes [#7441](https://github.com/ClickHouse/ClickHouse/issues/7441) [#9257](https://github.com/ClickHouse/ClickHouse/pull/9257) ([Mikhail Korotov](https://github.com/millb))

-* Added range check to function `h3EdgeLengthM`. Without this check, buffer overflow is possible. [#8945](https://github.com/ClickHouse/ClickHouse/pull/8945) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Fixed up a bug in batched calculations of ternary logical OPs on multiple arguments (more than 10). [#8718](https://github.com/ClickHouse/ClickHouse/pull/8718) ([Alexander Kazakov](https://github.com/Akazz))

-* Fix unexpected `Timeout exceeded while reading from socket` exception, which randomly happens on secure connection before timeout actually exceeded and when query profiler is enabled. Also add `connect_timeout_with_failover_secure_ms` settings (default 100ms), which is similar to `connect_timeout_with_failover_ms`, but is used for secure connections (because SSL handshake is slower, than ordinary TCP connection) [#9026](https://github.com/ClickHouse/ClickHouse/pull/9026) ([tavplubix](https://github.com/tavplubix))
-* Fix bug with mutations finalization, when mutation may hang in state with `parts_to_do=0` and `is_done=0`. [#9022](https://github.com/ClickHouse/ClickHouse/pull/9022) ([alesapin](https://github.com/alesapin))
-* Use new ANY JOIN logic with `partial_merge_join` setting. It's possible to make `ANY|ALL|SEMI LEFT` and `ALL INNER` joins with `partial_merge_join=1` now. [#8932](https://github.com/ClickHouse/ClickHouse/pull/8932) ([Artem Zuikov](https://github.com/4ertus2))
-* Shard now clamps the settings got from the initiator to the shard's constaints instead of throwing an exception. This fix allows to send queries to a shard with another constraints. [#9447](https://github.com/ClickHouse/ClickHouse/pull/9447) ([Vitaly Baranov](https://github.com/vitlibar))
-* Fixed memory management problem in `MergeTreeReadPool`. [#8791](https://github.com/ClickHouse/ClickHouse/pull/8791) ([Vladimir Chebotarev](https://github.com/excitoon))
-* Fix `toDecimal*OrNull()` functions family when called with string `e`. Fixes [#8312](https://github.com/ClickHouse/ClickHouse/issues/8312) [#8764](https://github.com/ClickHouse/ClickHouse/pull/8764) ([Artem Zuikov](https://github.com/4ertus2))
-* Make sure that `FORMAT Null` sends no data to the client. [#8767](https://github.com/ClickHouse/ClickHouse/pull/8767) ([Alexander Kuzmenkov](https://github.com/akuzm))
-* Fix bug that timestamp in `LiveViewBlockInputStream` will not updated. `LIVE VIEW` is an experimental feature. [#8644](https://github.com/ClickHouse/ClickHouse/pull/8644) ([vxider](https://github.com/Vxider)) [#8625](https://github.com/ClickHouse/ClickHouse/pull/8625) ([vxider](https://github.com/Vxider))

-* Fixed the behaviour of `match` and `extract` functions when haystack has zero bytes. The behaviour was wrong when haystack was constant. This fixes [#9160](https://github.com/ClickHouse/ClickHouse/issues/9160) [#9163](https://github.com/ClickHouse/ClickHouse/pull/9163) ([alexey-milovidov](https://github.com/alexey-milovidov)) [#9345](https://github.com/ClickHouse/ClickHouse/pull/9345) ([alexey-milovidov](https://github.com/alexey-milovidov))

[#9033](https://github.com/ClickHouse/ClickHouse/pull/9033) ([Artem Zuikov](https://github.com/4ertus2))
-* Add setting `enable_early_constant_folding` and disable it in some cases that leads to errors. [#9010](https://github.com/ClickHouse/ClickHouse/pull/9010) ([Artem Zuikov](https://github.com/4ertus2))
-* Fix pushdown predicate optimizer with VIEW and enable the test [#9011](https://github.com/ClickHouse/ClickHouse/pull/9011) ([Winter Zhang](https://github.com/zhang2014))
-* Fix segfault in `Merge` tables, that can happen when reading from `File` storages [#9387](https://github.com/ClickHouse/ClickHouse/pull/9387) ([tavplubix](https://github.com/tavplubix))
-* Added a check for storage policy in `ATTACH PARTITION FROM`, `REPLACE PARTITION`, `MOVE TO TABLE`. Otherwise it could make data of part inaccessible after restart and prevent ClickHouse to start. [#9383](https://github.com/ClickHouse/ClickHouse/pull/9383) ([Vladimir Chebotarev](https://github.com/excitoon))
-* Fix alters if there is TTL set for table. [#8800](https://github.com/ClickHouse/ClickHouse/pull/8800) ([Anton Popov](https://github.com/CurtizJ))

This fixes [#9019](https://github.com/ClickHouse/ClickHouse/issues/9019) and [#8982](https://github.com/ClickHouse/ClickHouse/issues/8982). Additionally fix extremely rare race conditions in `ReplicatedMergeTree` `ALTER` queries. [#9048](https://github.com/ClickHouse/ClickHouse/pull/9048) ([alesapin](https://github.com/alesapin))
-* When the setting `compile_expressions` is enabled, you can get `unexpected column` in `LLVMExecutableFunction` when we use `Nullable` type [#8910](https://github.com/ClickHouse/ClickHouse/pull/8910) ([Guillaume Tassery](https://github.com/YiuRULE))
-* Multiple fixes for `Kafka` engine: 1) fix duplicates that were appearing during consumer group rebalance. 2) Fix rare 'holes' appeared when data were polled from several partitions with one poll and committed partially (now we always process / commit the whole polled block of messages). 3) Fix flushes by block size (before that only flushing by timeout was working properly). 4) better subscription procedure (with assignment feedback). 5) Make tests work faster (with default intervals and timeouts). Due to the fact that data was not flushed by block size before (as it should according to documentation), that PR may lead to some performance degradation with default settings (due to more often & tinier flushes which are less optimal). If you encounter the performance issue after that change - please increase `kafka_max_block_size` in the table to the bigger value ( for example `CREATE TABLE ...Engine=Kafka ... SETTINGS ... kafka_max_block_size=524288`). Fixes [#7259](https://github.com/ClickHouse/ClickHouse/issues/7259) [#8917](https://github.com/ClickHouse/ClickHouse/pull/8917) ([filimonov](https://github.com/filimonov))

-* When executing `CREATE` query, fold constant expressions in storage engine arguments. Replace empty database name with current database. Fixes [#6508](https://github.com/ClickHouse/ClickHouse/issues/6508), [#3492](https://github.com/ClickHouse/ClickHouse/issues/3492) [#9262](https://github.com/ClickHouse/ClickHouse/pull/9262) ([tavplubix](https://github.com/tavplubix))
-* Now it's not possible to create or add columns with simple cyclic aliases like `a DEFAULT b, b DEFAULT a`. [#9603](https://github.com/ClickHouse/ClickHouse/pull/9603) ([alesapin](https://github.com/alesapin))
-* Fixed a bug with double move which may corrupt original part. This is relevant if you use `ALTER TABLE MOVE` [#8680](https://github.com/ClickHouse/ClickHouse/pull/8680) ([Vladimir Chebotarev](https://github.com/excitoon))
-* Allow `interval` identifier to correctly parse without backticks. Fixed issue when a query cannot be executed even if the `interval` identifier is enclosed in backticks or double quotes. This fixes [#9124](https://github.com/ClickHouse/ClickHouse/issues/9124). [#9142](https://github.com/ClickHouse/ClickHouse/pull/9142) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Fixed fuzz test and incorrect behaviour of `bitTestAll`/`bitTestAny` functions. [#9143](https://github.com/ClickHouse/ClickHouse/pull/9143) ([alexey-milovidov](https://github.com/alexey-milovidov))

-* Fix bug in which a misleading error message was shown when running `SHOW CREATE TABLE a_table_that_does_not_exist`. [#8899](https://github.com/ClickHouse/ClickHouse/pull/8899) ([achulkov2](https://github.com/achulkov2))
-* Fixed `Parameters are out of bound` exception in some rare cases when we have a constant in the `SELECT` clause when we have an `ORDER BY` and a `LIMIT` clause. [#8892](https://github.com/ClickHouse/ClickHouse/pull/8892) ([Guillaume Tassery](https://github.com/YiuRULE))

-* During server startup do not access table, which `LIVE VIEW` depends on, so server will be able to start. Also remove `LIVE VIEW` dependencies when detaching `LIVE VIEW`. `LIVE VIEW` is an experimental feature. [#8824](https://github.com/ClickHouse/ClickHouse/pull/8824) ([tavplubix](https://github.com/tavplubix))
-* Fix possible segfault in `MergeTreeRangeReader`, while executing `PREWHERE`. [#9106](https://github.com/ClickHouse/ClickHouse/pull/9106) ([Anton Popov](https://github.com/CurtizJ))

-
-#### Improvement
-* Implement `ALTER MODIFY/DROP` queries on top of mutations for `ReplicatedMergeTree*` engines family. Now `ALTERS` blocks only at the metadata update stage, and don't block after that. [#8701](https://github.com/ClickHouse/ClickHouse/pull/8701) ([alesapin](https://github.com/alesapin))
-* Add ability to rewrite CROSS to INNER JOINs with `WHERE` section containing unqialified names. [#9512](https://github.com/ClickHouse/ClickHouse/pull/9512) ([Artem Zuikov](https://github.com/4ertus2))

-### ClickHouse release v20.1.2.4, 2020-01-22
-
-#### Backward Incompatible Change
-* Make the setting `merge_tree_uniform_read_distribution` obsolete. The server still recognizes this setting but it has no effect. [#8308](https://github.com/ClickHouse/ClickHouse/pull/8308) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Changed return type of the function `greatCircleDistance` to `Float32` because now the result of calculation is `Float32`. [#7993](https://github.com/ClickHouse/ClickHouse/pull/7993) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Now it's expected that query parameters are represented in "escaped" format. For example, to pass string `a<tab>b` you have to write `a\tb` or `a\<tab>b` and respectively, `a%5Ctb` or `a%5C%09b` in URL. This is needed to add the possibility to pass NULL as `\N`. This fixes [#7488](https://github.com/ClickHouse/ClickHouse/issues/7488). [#8517](https://github.com/ClickHouse/ClickHouse/pull/8517) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Enable `use_minimalistic_part_header_in_zookeeper` setting for `ReplicatedMergeTree` by default. This will significantly reduce amount of data stored in ZooKeeper. This setting is supported since version 19.1 and we already use it in production in multiple services without any issues for more than half a year. Disable this setting if you have a chance to downgrade to versions older than 19.1. [#6850](https://github.com/ClickHouse/ClickHouse/pull/6850) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Data skipping indices are production ready and enabled by default. The settings `allow_experimental_data_skipping_indices`, `allow_experimental_cross_to_join_conversion` and `allow_experimental_multiple_joins_emulation` are now obsolete and do nothing. [#7974](https://github.com/ClickHouse/ClickHouse/pull/7974) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Add new `ANY JOIN` logic for `StorageJoin` consistent with `JOIN` operation. To upgrade without changes in behaviour you need add `SETTINGS any_join_distinct_right_table_keys = 1` to Engine Join tables metadata or recreate these tables after upgrade. [#8400](https://github.com/ClickHouse/ClickHouse/pull/8400) ([Artem Zuikov](https://github.com/4ertus2))
-* Require server to be restarted to apply the changes in logging configuration. This is a temporary workaround to avoid the bug where the server logs to a deleted log file (see [#8696](https://github.com/ClickHouse/ClickHouse/issues/8696)). [#8707](https://github.com/ClickHouse/ClickHouse/pull/8707) ([Alexander Kuzmenkov](https://github.com/akuzm))

-* Improvements in consistency of `ANY JOIN` logic. Now `t1 ANY LEFT JOIN t2` equals `t2 ANY RIGHT JOIN t1`. [#7665](https://github.com/ClickHouse/ClickHouse/pull/7665) ([Artem Zuikov](https://github.com/4ertus2))
-* Add setting `any_join_distinct_right_table_keys` which enables old behaviour for `ANY INNER JOIN`. [#7665](https://github.com/ClickHouse/ClickHouse/pull/7665) ([Artem Zuikov](https://github.com/4ertus2))
-* Add new `SEMI` and `ANTI JOIN`. Old `ANY INNER JOIN` behaviour now available as `SEMI LEFT JOIN`. [#7665](https://github.com/ClickHouse/ClickHouse/pull/7665) ([Artem Zuikov](https://github.com/4ertus2))
-* Added `Distributed` format for `File` engine and `file` table function which allows to read from `.bin` files generated by asynchronous  inserts into `Distributed` table. [#8535](https://github.com/ClickHouse/ClickHouse/pull/8535) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
-* Add optional reset column argument for `runningAccumulate` which allows to reset aggregation results for each new key value. [#8326](https://github.com/ClickHouse/ClickHouse/pull/8326) ([Sergey Kononenko](https://github.com/kononencheg))
-* Add ability to use ClickHouse as Prometheus endpoint. [#7900](https://github.com/ClickHouse/ClickHouse/pull/7900) ([vdimir](https://github.com/Vdimir))
-* Add section `<remote_url_allow_hosts>` in `config.xml` which restricts allowed hosts for remote table engines and table functions `URL`, `S3`, `HDFS`. [#7154](https://github.com/ClickHouse/ClickHouse/pull/7154) ([Mikhail Korotov](https://github.com/millb))
-* Added function `greatCircleAngle` which calculates the distance on a sphere in degrees. [#8105](https://github.com/ClickHouse/ClickHouse/pull/8105) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Changed Earth radius to be consistent with H3 library. [#8105](https://github.com/ClickHouse/ClickHouse/pull/8105) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Added `JSONCompactEachRow` and `JSONCompactEachRowWithNamesAndTypes` formats for input and output. [#7841](https://github.com/ClickHouse/ClickHouse/pull/7841) ([Mikhail Korotov](https://github.com/millb))

[#7840](https://github.com/ClickHouse/ClickHouse/pull/7840) ([Andrey Bodrov](https://github.com/apbodrov))
-* Added the `randomASCII(length)` function, generating a string with a random set of [ASCII](https://en.wikipedia.org/wiki/ASCII#Printable_characters) printable characters. [#8401](https://github.com/ClickHouse/ClickHouse/pull/8401) ([BayoNet](https://github.com/BayoNet))
-* Added function `JSONExtractArrayRaw` which returns an array on unparsed json array elements from `JSON` string. [#8081](https://github.com/ClickHouse/ClickHouse/pull/8081) ([Oleg Matrokhin](https://github.com/errx))
-* Add `arrayZip` function which allows to combine multiple arrays of equal lengths into one array of tuples. [#8149](https://github.com/ClickHouse/ClickHouse/pull/8149) ([Winter Zhang](https://github.com/zhang2014))

-* Better compatibility with MySQL clients which don't support `sha2_password` auth plugin. [#8036](https://github.com/ClickHouse/ClickHouse/pull/8036) ([Yuriy Baranov](https://github.com/yurriy))
-* Support more column types in MySQL compatibility server. [#7975](https://github.com/ClickHouse/ClickHouse/pull/7975) ([Yuriy Baranov](https://github.com/yurriy))
-* Implement `ORDER BY` optimization for `Merge`, `Buffer` and `Materilized View` storages with underlying `MergeTree` tables. [#8130](https://github.com/ClickHouse/ClickHouse/pull/8130) ([Anton Popov](https://github.com/CurtizJ))
-* Now we always use POSIX implementation of `getrandom` to have better compatibility with old kernels (< 3.17). [#7940](https://github.com/ClickHouse/ClickHouse/pull/7940) ([Amos Bird](https://github.com/amosbird))
-* Better check for valid destination in a move TTL rule. [#8410](https://github.com/ClickHouse/ClickHouse/pull/8410) ([Vladimir Chebotarev](https://github.com/excitoon))

-* Parallel merge sort optimization for processors. [#8552](https://github.com/ClickHouse/ClickHouse/pull/8552) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
-* The settings `mark_cache_min_lifetime` is now obsolete and does nothing. In previous versions, mark cache can grow in memory larger than `mark_cache_size` to accomodate data within `mark_cache_min_lifetime` seconds. That was leading to confusion and higher memory usage than expected, that is especially bad on memory constrained systems. If you will see performance degradation after installing this release, you should increase the `mark_cache_size`. [#8484](https://github.com/ClickHouse/ClickHouse/pull/8484) ([alexey-milovidov](https://github.com/alexey-milovidov))
-* Preparation to use `tid` everywhere. This is needed for [#7477](https://github.com/ClickHouse/ClickHouse/issues/7477). [#8276](https://github.com/ClickHouse/ClickHouse/pull/8276) ([alexey-milovidov](https://github.com/alexey-milovidov))

-
-#### Experimental Feature
-* Added experimental setting `min_bytes_to_use_mmap_io`. It allows to read big files without copying data from kernel to userspace. The setting is disabled by default. Recommended threshold is about 64 MB, because mmap/munmap is slow. [#8520](https://github.com/ClickHouse/ClickHouse/pull/8520) ([alexey-milovidov](https://github.com/alexey-milovidov))
