Version 3.0.4

Released on 2018/07/23.

Note

If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.0.4.

We recommend that you upgrade to the latest 2.3 release before moving to 3.0.4.

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.

Warning

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.

Warning

Before upgrading, you should back up your data.

Fixes

  • Fixed an issue which prevented adding new string typed columns into dynamic objects if a cluster was initially created with a version between 1.1.0 and 2.0.0.
  • Fixed an issue that caused runtime changes to the indices.breaker.query.limit and indices.breaker.query.overhead settings to be ignored when using the SET GLOBAL [TRANSIENT] command.
  • Stored the correct name (timestamptz) for the timestamp type in the pg_type table.
  • Fixed an issue that caused an UnsupportedFeatureException to be thrown when deleting or updating by query on an empty partitioned table, instead of just returning 0 rows deleted/updated.
