Release 0.191

    • Fix bit_count() for bits between 33 and 63.

    • Add support for grouped join execution. When both sides of a join have the same table partitioning and the partitioning is addressable, partial data can be loaded into memory at a time, making it possible to execute the join with less peak memory usage. The colocated join feature must be enabled with the config property or the colocated_join session property, and the concurrent_lifespans_per_task session property must be specified.

    Resource Groups Changes

    • Add query type to the exact match source selector in the DB resource group selectors.
    • Improve display of values of the Geometry type.

    Hive Changes

    • Report physical written data for the legacy RCFile writer, optimized RCFile writer, and optimized ORC writer. These writers thus support writer scaling, which can both reduce the number of written files and create larger files. This is especially important for tables that have many small partitions, as small files can take a disproportionately longer time to read.

    • Add page size distribution metrics.

    MySQL, PostgreSQL, Redshift, and SQL Server Changes
