Version 3.1.1¶
Released on 2018/09/25.
Note
If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.1.1.
We recommend that you upgrade to the latest 3.0 release before moving to 3.1.1.
You cannot perform a rolling upgrade to this version. Any upgrade to this version 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.
Warning
Tables that were created prior to upgrading to CrateDB 2.x will not function with 3.1 and must be recreated before moving to 3.1.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.
