Version 3.0.7

Released on 2018/09/25.


If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.0.7.

We recommend that you upgrade to the latest 2.3 release before moving to 3.0.7.

If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 3.0.0. Any upgrade from a version prior to this will require a full restart upgrade.

When restarting, CrateDB will migrate indexes to a newer format. Depending on the amount of data, this may delay node start-up time.

Please consult the Upgrade Notes before upgrading.


Tables that were created prior to upgrading to CrateDB 2.x will not function with 3.0 and must be recreated before moving to 3.0.x.

You can recreate tables using COPY TO and COPY FROM while running a 2.x release into a new table, or by inserting the data into a new table.


Before upgrading, you should back up your data.

Breaking Changes

  • Previously, Version 3.0.0 advertised a breaking change for the removal of the region setting when using the CREATE REPOSITORY query for S3 based snapshot repositories. However, due to a bug, using the region setting was valid syntax in versions 3.0.0 through to 3.0.6.

    This bug has been fixed in 3.0.7. Due to this, CREATE REPOSITORY queries that were accepted (erroneously) in 3.0.6 may no longer work in 3.0.7.


  • Calling an unknown user defined function now results in an appropriate error message instead of a NullPointerException.
  • Trying to create a table with a generated column inside an object column now results in a friendly error message instead of a NullPointerException.
  • Fixed processing of the endpoint, protocol and max_retries S3 repository parameters.
