  • Add support for reading data as tinyint and smallint types rather than integer.


  • Remove owner from ConnectorTableMetadata.

  • Replace the generic getServices() method in Plugin with specific methods such as getConnectorFactories(), getTypes(), etc. Dependencies like TypeManager are now provided directly rather than being injected into Plugin.

  • Add first-class support for functions in the SPI. This replaces the old FunctionFactory interface. Plugins can return a list of classes from the getFunctions() method:

    • Scalar functions are methods or classes annotated with @ScalarFunction.

    • Aggregation functions are methods or classes annotated with @AggregationFunction.

    • Window functions are an implementation of WindowFunction. Most implementations should be a subclass of RankingWindowFunction or ValueWindowFunction.


This is a backwards incompatible change with the previous SPI. If you have written a plugin, you will need to update your code before deploying this release.


  • Fix handling of shadow write queries with a LIMIT.

Local file#

  • Fix file descriptor leak.
