Fix error in implementation of `substringUTF8` function with negative offset (offset from the end of string). The functions `left` and `right` were previously implemented in parser. Upgrade notes: 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)). -* - Account for scalar subqueries. 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)). -* Change ZooKeeper path for zero-copy marks for shared data. Fix for remove marks in ZooKeeper for renamed parts. [#32061](https://github.com/ClickHouse/ClickHouse/pull/32061) ([ianton-ru](https://github.com/ianton-ru)). +* 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 -* Detect format by file extension in file/hdfs/s3/url table functions and HDFS/S3/URL table engines. [#33565](https://github.com/ClickHouse/ClickHouse/pull/33565) ([Kruglov Pavel](https://github.com/Avogar)). -* Add new h3 miscellaneous functions: `h3DegsToRads`, `h3RadsToDegs`, `h3HexAreaKm2`, `h3CellAreaM2`, `h3CellAreaRads2`.

[#33415](https://github.com/ClickHouse/ClickHouse/pull/33415) ([Maksim Kita](https://github.com/kitaisreal)). -* Add aggregate functions `cramersV`, `cramersVBiasCorrected`, `theilsU` and `contingency`. These functions calculate dependency (measure of association) between categorial 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)). -* If an invalid setting is defined using the `SET` query or using the query parameters in the HTTP request, error message will contain suggestions that are similar to the invalid setting string (if any exists).

[#32836](https://github.com/ClickHouse/ClickHouse/pull/32836) ([Stig Bakken](https://github.com/stigsb)). -* Support TABLE OVERRIDE clause for MaterializedPostgreSQL. RFC: [#31480](https://github.com/ClickHouse/ClickHouse/issues/31480). [#32749](https://github.com/ClickHouse/ClickHouse/pull/32749) ([Kseniia Sumarokova](https://github.com/kssenii)). * 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)). -* Added table function hdfsCluster which allows processing files from HDFS in parallel from many nodes in a specified cluster. [#32400](https://github.com/ClickHouse/ClickHouse/pull/32400) ([Zhichang Yu](https://github.com/yuzhichang)). -* * Add "TABLE OVERRIDE" feature for customizing MaterializedMySQL table schemas. [#32325](https://github.com/ClickHouse/ClickHouse/pull/32325) ([Stig Bakken](https://github.com/stigsb)). -* Adding support for disks backed by Azure Blob Storage, in a similar way it has been done for disks backed by AWS S3.

[#31062](https://github.com/ClickHouse/ClickHouse/pull/31062) ([Vasily Nemkov](https://github.com/Enmk)). -* Start and stop servers when hosts and ports configuration changes. [#30549](https://github.com/ClickHouse/ClickHouse/pull/30549) ([Kevin Michel](https://github.com/kmichel-aiven)). -* Added an ability to read from all replicas within a shard during distributed query. To enable this, set `allow_experimental_parallel_reading_from_replicas=true` 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)). -* add grouping sets function, like GROUP BY grouping sets (a, b, (a, b)). [#26869](https://github.com/ClickHouse/ClickHouse/pull/26869) ([taylor12805](https://github.com/taylor12805)). -* 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)). +* 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)).
