2022 Changelog

ClickHouse release v22.7.1.2484-stable (f4f05ec786) FIXME as compared to v22.6.1.1985-stable (7000c4e003)

Backward Incompatible Change

• Enable setting enable_positional_arguments by default. It allows queries like SELECT ... ORDER BY 1, 2 where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. #38204 (Alexey Milovidov).
• Ordinary database engine and old storage definition syntax for *MergeTree tables are deprecated. By default it's not possible to create new ones. If system database has Ordinary engine it will be automatically converted to Atomic on server startup. There are settings to keep old behavior (allow_deprecated_database_ordinary and allow_deprecated_syntax_for_merge_tree), but these settings may be removed in future releases. #38335 (Alexander Tokmakov).
• • Force rewriting comma join to inner by default (set default value cross_to_inner_join_rewrite = 2). To have old behavior set cross_to_inner_join_rewrite = 1. #39326 (Vladimir C).
• Disable format_csv_allow_single_quotes by default. #37096. #39423 (Kruglov Pavel).

New Feature

• Add new direct join algorithm for RocksDB, ref #33582. #35363 (Vladimir C).
• • Added full sorting merge join algorithm. #35796 (Vladimir C).
• Add a setting zstd_window_log_max to configure max memory usage on zstd decoding when importing external files. Closes #35693. #37015 (wuxiaobai24).
• Implement NatsStorage - table engine, which allows to pub/sub to NATS. Closes #32388. #37171 (tchepavel).
• Implement table function MongoDB. Allow writes into MongoDB storage / table function. #37213 (aaapetrenko).
• clickhouse-keeper new feature: add support for real-time digest calculation and verification. #37555 (Antonio Andelic).
• In #17202 was reported that host_regexp was being tested against only one of the possible PTR responses. This PR makes the necessary changes so that host_regexp is applied against all possible PTR responses and validate if any matches. #37827 (Arthur Passos).
• Support hadoop secure rpc transfer(hadoop.rpc.protection=privacy and hadoop.rpc.protection=integrity). #37852 (Peng Liu).
• Add struct type support in StorageHive. #38118 (lgbo).
• Added Base58 encoding/decoding. #38159 (Andrey Zvonov).
• Add chart visualization to Play UI. #38197 (Alexey Milovidov).
• support alter command on StorageHive table. #38214 (lgbo).
• Added CREATE TABLE ... EMPTY AS SELECT query. It automatically deduces table structure from the SELECT query, but does not fill the table after creation. Resolves #38049. #38272 (Alexander Tokmakov).
• Adds new setting implicit_transaction to run standalone queries inside a transaction. It handles both creation and closing (via COMMIT if the query succeeded or ROLLBACK if it didn't) of the transaction automatically. #38344 (Raúl Marín).
• Allow trailing comma in columns list. closes #38425. #38440 (chen).
• Compress clickhouse into self-extracting executable (path programs/self-extracting). New build target 'self-extracting' is added. #38447 (Yakov Olkhovskiy).
• Introduced settings additional_table_filters. Using this setting, you can specify additional filtering condition for a table which will be applied directly after reading. Example: select number, x, y from (select number from system.numbers limit 5) f any left join (select x, y from table_1) s on f.number = s.x settings additional_table_filters={'system.numbers : 'number != 3', 'table_1' : 'x != 2'}. Introduced setting additional_result_filter which specifies additional filtering condition for query result. Closes #37918. #38475 (Nikolai Kochetov).
• Add SQLInsert output format. Closes #38441. #38477 (Kruglov Pavel).
• Downloadable clickhouse executable is compressed self-extracting. #38653 (Yakov Olkhovskiy).
• Support isNullable function. This function checks whether it's argument is nullable and return true(1) or false(0). Closes #38611. #38841 (lokax).
• Add functions translate(string, from_string, to_string) and translateUTF8(string, from_string, to_string). #38935 (Nikolay Degterinsky).
• Add compatibility setting and system.settings_changes system table that contains information about changes in settings through ClickHouse versions. Closes #35972. #38957 (Kruglov Pavel).
• Add the 3rd parameter to the tupleElement function and return it if tuple doesn't have a member. Only works if the 2nd parameter is of type String. Closes #38872. #38989 (lokax).
• Support parseTimedelta function. It can be used like ```sql # ' ', ';', '-', '+', ',', ':' can be used as separators, eg. "1yr-2mo", "2m:6s" SELECT parseTimeDelta('1yr-2mo-4w + 12 days, 3 hours : 1 minute ; 33 seconds');. #39071 (jiahui-97).
• Added options to limit IO operations with remote storage: max_remote_read_network_bandwidth_for_server and max_remote_write_network_bandwidth_for_server. #39095 (Sergei Trifonov).
• Add send_logs_source_regexp setting. Send server text logs with specified regexp to match log source name. Empty means all sources. #39161 (Amos Bird).
• OpenTelemetry now collects traces without Processors spans by default. To enable Processors spans collection opentelemetry_trace_processors setting. #39170 (Ilya Yatsishin).
