See the Version 4.6.0 release notes for a full list of changes in the 4.6 series.


  • Fixed a performance regression introduced in 4.2 which caused queries with a LIMIT on top of views or virtual tables with an ORDER BY to be slow.

  • Fixed an issue in the Query View function of the administration console. It generated queries with extra quotes around identifiers.

  • Fixed an issue that could cause clients to receive a 400 Bad Request error when using the HTTP interface early during node startup.

  • Fixed an issue that resulted in broken values when selecting multiple object columns with different inner types using the UNION statement.

  • Fixed an issue which caused object data types definitions with sub-column identifiers containing white spaces to result in a validation exception at CrateDB 4.6.2 or a unusable object type column (write/reads fail) at CrateDB 4.2.0 to 4.6.1.
