13.34. Release 0.209

    • Fix incorrect predicate pushdown when grouping sets contain the empty grouping set (#11296).
    • Fix header handling for requests to the / path ().
    • Fix a regression that results in execution failure when at least one of the arguments to min_by() or is a constant NULL.
    • Fix failure when some buckets are completely filtered out during bucket-by-bucket execution.
    • Fix execution failure of queries due to a planning deficiency involving complex nested joins where a join that is not eligible for bucket-by-bucket execution feeds into the build side of a join that is eligible.
    • Do not include column aliases when checking column access permissions.
    • Eliminate unnecessary data redistribution for scalar correlated subqueries.
    • Remove table scan original constraint information from EXPLAIN output.
    • Introduce distinct error codes for global and per-node memory limit errors.
    • Include statistics and cost estimates for EXPLAIN (TYPE DISTRIBUTED) and EXPLAIN ANALYZE.
    • Support equality checks for ARRAY, MAP, and ROW values containing nulls.
    • Improve statistics estimation and fix potential negative nulls fraction estimates for expressions that include NOT or .
    • Completely remove the SHOW PARTITIONS statement.
    • Add bing_tiles_around() variant that takes a radius.
    • Add the and geometry_union_agg() geospatial aggregation functions.
    • Add (TYPE IO, FORMAT JSON) option for that shows input tables with constraints and the output table in JSON format.
    • Add Kudu Connector.

    Web UI Changes

    • Fix the kill query button on the live plan and stage performance pages.
    • Prevent spurious “No route to host” errors on macOS when using IPv6.

    JDBC Driver Changes

    • Prevent spurious “No route to host” errors on macOS when using IPv6.
    • Fix data loss when writing bucketed sorted tables. Partitions would be missing arbitrary rows if any of the temporary files for a bucket had the same size. The numRows partition property contained the correct number of rows and can be used to detect if this occurred.
    • Fix cleanup of temporary files when writing bucketed sorted tables.
    • Allow creating schemas when using file based security.
    • Reduce the number of cases where tiny ORC stripes will be written when some columns are highly dictionary compressed.
    • Improve memory accounting when reading ORC files. Previously, buffer memory and object overhead was not tracked for stream readers.
    • ORC struct columns are now mapped by name rather than ordinal. This correctly handles missing or extra struct fields in the ORC file.
    • Add procedure for creating empty partitions.

    Kafka Connector Changes

    • Support Avro formatted Kafka messages.
    • Support backward compatible Avro schema evolution.
