Version 3.3.5¶

Released on 2019/07/08.

Note

If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.3.5.

We recommend that you upgrade to the latest 3.2 release before moving to 3.3.5.

If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 3.3.0. 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 3.3 and must be recreated before moving to 3.3.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.

Changelog ¶

Fixed the tables compatibility check to correctly indicate when tables need to be recreated in preparation for a CrateDB upgrade towards the next major version of CrateDB.
The values provided in INSERT or UPDATE statements for object columns which contain generated expressions are now validated. The computed expression must match the provided value. This makes the behavior consistent with how top level columns of a table are treated.
Fixed support for ordering by literal constants.

Example: SELECT 1, * FROM t ORDER BY 1"
