Version 5.7.2 - Unreleased¶

Note

In development. 5.7.2 isn’t released yet. These are the release notes for the upcoming release.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.7.2.

We recommend that you upgrade to the latest 5.6 release before moving to 5.7.2.

A rolling upgrade from 5.6.x to 5.7.2 is supported.

Before upgrading, you should back up your data.

Warning

Tables that were created before CrateDB 4.x will not function with 5.x and must be recreated before moving to 5.x.x.

You can recreate tables using COPY TO and COPY FROM or by inserting the data into a new table.

See the Version 5.7.0 release notes for a full list of changes in the 5.7 series.

Fixes ¶

Added memory accounting for multi-phase execution to prevent out-of-memory errors caused by sub-queries such as ‘’SELECT * FROM t1 WHERE id IN (SELECT id FROM t2)’’ or lookup-joins with large intermediate results.
