Bug fixes

  • Fixed a bug where some import failures would cause tables to stay OFFLINE when they should have been brought back to PUBLIC. #61481
  • Fixed a bug where an invalid tuple comparison using ANY was causing an internal error. CockroachDB now returns "unsupported comparison operator". #61725
  • Changed the behavior of the kv.closed_timestamp.target_duration cluster setting when set to 0. This would make follower reads more aggressive instead of disabling them. Setting kv.closed_timestamp.target_duration to 0 will now disable routing requests to follower replicas. #62442
  • Fixed a bug where RESTORE using AS OF SYSTEM TIME of tables that included foreign key constraints from backups created by v19.x or earlier would lead to malformed schema metadata. #62493
  • Fixed an internal error that could occur during planning when a query used the output of the RETURNING clause of an UPDATE, and one or more of the columns in the RETURNING clause were from a table specified in the FROM clause of the UPDATE (i.e., not from the table being updated). #62964
  • Dropping a foreign key that was added in the same transaction no longer triggers an internal error. This bug has been present since at least v20.1. #62881
  • Fixed a bug where index backfill data might have been missed by BACKUP in incremental backups. #63303

Performance improvements

  • SQL statistics collection has been made more efficient by avoiding an accidental heap allocation per row for some schemas. #58199
