# 2022 Changelog
### ClickHouse release v21.10.1.8013-prestable FIXME as compared to v21.9.1.7770-prestable
#### Backward Incompatible Change
* Fix the issue that in case of some sophisticated query with column aliases identical to the names of expressions, bad cast may happen. This fixes [#25447](https://github.com/ClickHouse/ClickHouse/issues/25447). This fixes [#26914](https://github.com/ClickHouse/ClickHouse/issues/26914). This fix may introduce backward incompatibility: if there are different expressions with identical names, exception will be thrown. It may break some rare cases when `enable_optimize_predicate_expression` is set. [#26639](https://github.com/ClickHouse/ClickHouse/pull/26639) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Do not output trailing zeros in text representation of `Decimal` types. Example: `1.23` will be printed instead of `1.230000` for decimal with scale 6. This closes [#15794](https://github.com/ClickHouse/ClickHouse/issues/15794). It may introduce slight incompatibility if your applications somehow relied on the trailing zeros. Serialization in output formats can be controlled with the setting `output_format_decimal_trailing_zeros`. Implementation of `toString` and casting to String is changed unconditionally. [#27680](https://github.com/ClickHouse/ClickHouse/pull/27680) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Now MergeTreeSettings `replicated_max_parallel_sends`, `replicated_max_parallel_sends_for_table`, `replicated_max_parallel_fetches`, `replicated_max_parallel_fetches_for_table` do nothing. They never worked well and were replaced with `max_replicated_fetches_network_bandwidth`, `max_replicated_sends_network_bandwidth` and `background_fetches_pool_size`. [#28404](https://github.com/ClickHouse/ClickHouse/pull/28404) ([alesapin](https://github.com/alesapin)).

* Add feature for creating user-defined functions as lambda expressions. Syntax `CREATE FUNCTION {function_name} as ({parameters}) -> {function core}`. Example `CREATE FUNCTION plus_one as (a) -> a + 1`. Authors @Realist007. [#27796](https://github.com/ClickHouse/ClickHouse/pull/27796) ([Maksim Kita](https://github.com/kitaisreal)).
* Add `getServerPort` function to allow getting server port. When the port is not used by the server, throw an exception. [#27900](https://github.com/ClickHouse/ClickHouse/pull/27900) ([Amos Bird](https://github.com/amosbird)).

#### Performance Improvement
* Introducing two checks in `sequenceMatch` and `sequenceCount` that allow for early exit when some deterministic part of the sequence pattern is missing from the events list. This change unlocks many queries that would previously fail due to reaching operations cap, and generally speeds up the pipeline. [#27729](https://github.com/ClickHouse/ClickHouse/pull/27729) ([Jakub Kuklis](https://github.com/jkuklis)).

#### Improvement
* Create virtual projection for `min_max` indices. Now, when `allow_experimental_projection_optimization ` is enabled, queries will use minmax index instead of reading a part when possible. [#26286](https://github.com/ClickHouse/ClickHouse/pull/26286) ([Amos Bird](https://github.com/amosbird)).

* Add `log_queries_probability` setting that allows user to write to query_log only a sample of queries. Closes [#16609](https://github.com/ClickHouse/ClickHouse/issues/16609). [#27527](https://github.com/ClickHouse/ClickHouse/pull/27527) ([Nikolay Degterinsky](https://github.com/evillique)).

* Added `replication_wait_for_inactive_replica_timeout` setting. It allows to specify how long to wait for inactive replicas to execute `ALTER`/`OPTIMZE`/`TRUNCATE` query (default is 120 seconds). If `replication_alter_partitions_sync` is 2 and some replicas are not active for more than `replication_wait_for_inactive_replica_timeout` seconds, then `UNFINISHED` will be thrown.

* Add a setting `empty_result_for_aggregation_by_constant_keys_on_empty_set` to control the behavior of grouping by constant keys on empty set.

* Enable optimize_distributed_group_by_sharding_key by default. [#28105](https://github.com/ClickHouse/ClickHouse/pull/28105) ([Azat Khuzhin](https://github.com/azat)).
* Fix `zookeeper_log.address` (before the first patch in this PR the address was always `::`) and reduce number of calls `getpeername(2)` for this column (since each time entry for `zookeeper_log` is added `getpeername()` is called, cache this address in the zookeeper client to avoid this). [#28212](https://github.com/ClickHouse/ClickHouse/pull/28212) ([Azat Khuzhin](https://github.com/azat)).
