Version 5.9.9

Released on 2025-01-30.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.9.9.

We recommend that you upgrade to the latest 5.8 release before moving to 5.9.9.

A rolling upgrade from 5.8.x to 5.9.9 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.

Fixes

  • Fixed an issue that could lead to a Scale of numeric must be less than the precision error when using the AVG aggregation in a way that involved values of type NUMERIC.

  • Fixed an issue that could cause data loss if increasing the number of shards using ALTER TABLE ... SET (number_of_shards = ?) while having other allocation settings in place that prevent the shard allocation.

  • Fixed an issue that could cause duplicate records to be returned when filtering on a table by PRIMARY KEY, using query parameters, and binding the same value to them, e.g.:

    SELECT * FROM tbl WHERE pk_col = ? OR pk_col = ?
-- Bind the same value to both query parameters

  • Fixed an issue that caused an error when using a PreparedStatement and selecting an expression, involving a parameter and a column used in ORDER BY and query had a LIMIT clause. Example.:

    SELECT a, b + ? as sum FROM tbl ORDER BY sum LIMIT 10
