:::{warning} The {func}xxhash64 function introduced in this release will return a varbinary instead of a bigint in the next release. :::

General

  • Fix correctness issue when the type of the value in the IN predicate does not match the type of the elements in the subquery.
  • Fix correctness issue when the value on the left-hand side of an IN expression or a quantified comparison is NULL.
  • Fix correctness issue when the subquery of a quantified comparison produces no rows.
  • Fix correctness issue due to improper inlining of TRY arguments.
  • Fix correctness issue when the right side of a JOIN produces a very large number of rows.
  • Fix correctness issue for expressions with multiple nested AND and OR conditions.
  • Improve performance of window functions with similar PARTITION BY clauses.
  • Improve performance of certain multi-way JOINs by automatically choosing the best evaluation order. This feature is turned off by default and can be enabled via the reorder-joins config option or reorder_joins session property.
  • Add {func}xxhash64 and {func}to_big_endian_64 functions.
  • Add aggregated operator statistics to final query statistics.
  • Allow specifying column comments for {doc}/sql/create-table.

Hive

  • Fix performance regression when querying Hive tables with large numbers of partitions.

SPI

  • Connectors can now return optional output metadata for write operations.
  • Add ability for event listeners to get connector-specific output metadata.
  • Add client-supplied payload field X-Presto-Client-Info to EventListener.
