General Changes

  • Fix potential correctness issue in queries that contain correlated scalar aggregation subqueries.
  • Fix query failure when using AT TIME ZONE in VALUES list.
  • Add support for quantified comparison predicates: ALL, ANY, and SOME.
  • Add support for ARRAY and ROW that contain NULL in checksum() aggregation.
  • Add support for filtered aggregations. Example: SELECT sum(a) FILTER (WHERE b > 0) FROM ...
  • Add a variant of from_unixtime() function that takes a timezone argument.
  • Improve performance of GROUP BY queries that compute a mix of distinct and non-distinct aggregations. This optimization can be turned on by setting the optimizer.optimize-mixed-distinct-aggregations configuration option or via the optimize_mixed_distinct_aggregations session property.

Hive Changes

  • Add support for legacy RCFile header version in new RCFile reader.
