Release 0.154#

General#

  • Fix planning issue that could cause JOIN queries involving functions that return null on non-null input to produce incorrect results.

  • Fix regression that would cause certain queries involving uncorrelated subqueries in IN predicates to fail during planning.

  • Fix potential «Input symbols do not match output symbols» error when writing to bucketed tables.

  • Fix potential «Requested array size exceeds VM limit» error that triggers the JVM’s OutOfMemoryError handling.

  • Improve performance of window functions with identical partitioning and ordering but different frame specifications.

  • Add code-cache-collection-threshold config which controls when Presto will attempt to force collection of the JVM code cache and reduce the default threshold to 40%.

  • Add support for using LIKE with CREATE TABLE.

  • Add support for DESCRIBE INPUT to describe the requirements for the input parameters to a prepared statement.

Hive#

  • Fix handling of metastore cache TTL. With the introduction of the per-transaction cache, the cache timeout was reset after each access, which means cache entries might never expire.
