Version 4.0.11

Released on 2020/01/15.

Note

Please consult the Upgrade Notes before upgrading from CrateDB 3.x or earlier. Before upgrading to 4.0.11 you should be running a CrateDB cluster that is at least on 3.0.7.

We recommend that you upgrade to the latest 3.3 release before moving to 4.0.11.

If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 4.0.2. 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.

Warning

Tables that were created prior CrateDB 3.x will not function with 4.x and must be recreated before moving to 4.x.x.

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

Before upgrading, you should back up your data.

Fixes

  • Fixed an issue that prevented statements from showing up in sys.jobs_log if they run into an error.

  • Fixed an NPE which occurred when using the current_timestamp inside the WHERE clause on a view relation.

  • Fixed the data type of the sys.jobs_metrics.classification['labels'] column, should be text_array instead of an undefined type.

  • Fixed an issue that caused a type cast error in INSERT statements if the target table contained a array(object() as (...) column where a child of the object array contained a NOT NULL constraint.

  • Fixed a NullPointerException that could prevent a node from starting up. This could occur if the node crashed or disconnected while a user deleted a table.

  • Improved the memory accounting for values of type geo_shape, object or undefined. Previously an arbitrary fixed value was used for memory accounting. If the actual payloads are large, this could have led to out of memory errors as the memory usage was under-estimated.

  • Fixed the type information of the fs['data'] and fs['disks'] column in the sys.nodes table. Querying those columns could have resulted in serialization errors.

  • Fixed the support for the readonly property in CREATE REPOSITORY.

  • Fixed an issue that may cause a SELECT query to hang on multiple nodes cluster if a resource error like a CircuitBreakingException occurs.

  • Fixed an issue that caused a INSERT INTO ... (SELECT ... FROM ..) statement to fail if not all partition columns appeared in the target list of the INSERT INTO statement.
