If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 4.6.2.

  • Fixed a validation issue resulting in an unusable broken table when a sub-column identifier of an object type column contains invalid whitespace characters.

  • Fixed an issue that could cause queries on sys.snapshots to fail with an error if a repository is in the cluster state that cannot be accessed - for example due to invalid credentials.

  • Fixed a regression introduced in CrateDB 4.6.0 that broke the functionality of restoring only concrete custom metadata like USERS, PRIVILEGES, VIEWS and UDFS.

  • Fixed an issue that caused the SHOW TRANSACTION_ISOLATION statement to require privileges for the sys schema.

  • Fixed an issue in the execution plan generation for SELECT COUNT(*) FROM ... statements with predicates like 'a' in ANY(varchar_array_column). Such predicates resulted in a cast on the column ('a' in ANY(varchar_array_column::array(varchar(1)))), leading to poor performance because the indices couldn’t get utilized. This fix significantly improves the performance of such queries. In a test over 100000 records, the query runtime improved from 320ms to 2ms.

  • Fixed an issue that could cause a NullPointerException if a user invoked a SELECT statement with a predicate on a OBJECT (ignored) column immediately after a DELETE statement.

  • Fixed an issue that could cause a wrong cast of numeric with parameters in arithmetical expressions.
