Version 6.2.9 - Unreleased

Note

In development. 6.2.9 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 5.0.0 or higher before you upgrade to 6.2.9.

We recommend that you upgrade to the latest 6.1 release before moving to 6.2.9.

A rolling upgrade from >= 6.1.2 to 6.2.9 is supported. Doing a rolling upgrade from an earlier version than 6.1.2 can cause runtime errors when executing statements relying on implicit casts.

Before upgrading, you should back up your data.

Warning

Tables that were created before CrateDB 5.x will not function with 6.x and must be recreated before moving to 6.x.x.

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

See the Version 6.2.0 release notes for a full list of changes in the 6.2 series.

Fixes

  • Fixed an issue that caused nodes to fail to start when parsing persisted mappings for tables containing columns of type uuid.

  • Fixed a regression introduced with Version 6.0.0, leading to stuck DROP SNAPSHOT and CREATE SNAPSHOT queries.

  • Fixed an issue causing cache to retain some heavy structures, potentially leading to an OutOfMemoryError.

  • Fixed an issue causing COUNT queries on a partitioned table to fail with ShardNotFoundException error if some partition shards were temporarily unavailable.
