Note
If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 4.2.4.

Fixes¶
- Fixed a performance regression that caused
SELECT
statements on tables with generated partition columns and a predicate that uses a column used to compute the partition column to hit all partitions instead of only a subset. - Fixed an issue that could lead to a
IndexOutOfBoundsException
when using virtual tables and joins. - Fixed an issue that declared the rule optimizer settings as global. The settings are now session local.
- Fixed an issue that prevented the
MATCH
predicate from working in mixed clusters running 4.1.8 and 4.2. - Fixed an issue that prevented user-defined functions in a custom schema from working if used in a generated column expression.
- Fixed an issue that allowed users to use a function in a generated column that didn’t fully match the given arguments, leading to a subsequent runtime failure when trying to access tables.
- Fixed exposure of the full qualified name of a sub-script column in information_schema.tables.partitioned_by and pg_catalog.pg_attribute.attname to use the CrateDB SQL compatible identifier.
- Fixed an issue that led to a
Message not fully read
error when trying to decommission a node usingALTER CLUSTER DECOMMISSION
. - Fixed an issue that resulted in incorrect results when querying the
sys.nodes
table. Predicates used in theWHERE
clause on columns that were absent in the select-list never matched.
