2023 Changelog

ClickHouse release v22.12.5.34-stable (b82d6401ca) FIXME as compared to v22.12.4.76-stable (cb5772db80)

Improvement

  • Backported in #46983: - Apply ALTER TABLE table_name ON CLUSTER cluster MOVE PARTITION|PART partition_expr TO DISK|VOLUME 'disk_name' to all replicas. Because ALTER TABLE t MOVE is not replicated. #46402 (lizhuoyu5).

Bug Fix (user-visible misbehavior in official stable or prestable release)

  • Backported in #45729: Fix key description when encountering duplicate primary keys. This can happen in projections. See #45590 for details. #45686 (Amos Bird).
  • Backported in #46398: Fix SYSTEM UNFREEZE queries failing with the exception CANNOT_PARSE_INPUT_ASSERTION_FAILED. #46325 (Aleksei Filatov).
  • Backported in #46903: - Fix incorrect alias recursion in QueryNormalizer. #46609 (Raúl Marín).
  • Backported in #47210: INSERT queries through native TCP protocol and HTTP protocol were not canceled correctly in some cases. It could lead to a partially applied query if a client canceled the query, or if a client died or, in rare cases, on network errors. As a result, it could lead to not working deduplication. Fixes #27667 and #45377. #46681 (Alexander Tokmakov).
  • Backported in #47157: - Fix arithmetic operations in aggregate optimization with min and max. #46705 (Duc Canh Le).
  • Backported in #46881: Fix MSan report in the maxIntersections function. This closes #43126. #46847 (Alexey Milovidov).
  • Backported in #47359: Fix possible deadlock on distributed query cancellation. #47161 (Kruglov Pavel).
