General Changes

  • Fix Queued Query Count JMX Metrics (:issue:19929). Expose the QueryManagerStats metrics under the com.facebook.presto.dispatcher:name=DispatchManager namespace.
  • Fix issue while using the iceberg table property format_version when iceberg.catalog.type is hive (:issue:19778).
  • Fix join output for CrossJoinWithOrFilterToInnerJoin optimizer rule. It will fix potential failures with the message "Not all left output variables are before right output variables" when rewrite_cross_join_or_to_inner_join is enabled.
  • Fix join output in RandomizeNullKeyInOuterJoin rule. It will fix failures with the message "Not all left output variables are before right output variables" when randomize_outer_join_null_key is enabled.
  • Fix join re-ordering issues observed when dynamic filtering is turned on.
  • Improve performance of getting resource group metrics.
  • Add a optimizer rule RemoveIdentityProjectionsBelowProjection to remove identity projections under project node.
  • Add a session parameter use_broadcast_when_buildsize_small_probeside_unknown to choose join distribution type This session is default to false. When enabled, broadcast join will be chosen when one side of input is within broadcast limit and the other side is unknow.
  • Add function :func:!any_keys_match.
  • Add function :func:!any_values_match.
  • Add option to add partial row number node for row number node with max count limit, enabled by session parameter add_partial_node_for_row_number_node_with_limit.
  • Add string functions :func:!starts_with and :func:!ends_with.
  • Add support for broadcast join in Presto-on-Spark/Velox execution path.
  • Add support for internal authentication using JWT. Can be configured using configs internal-communication.jwt.enabled=[true/false] and internal-communication.shared-secret=<shared-secret-value>.
  • Add support for worker isolation by configuring leaf and intermediate worker pools.
  • Add timeout for HBO optimizer, timeout set by session parameter history_based_optimizer_timeout_limit.
  • Added new property native-execution-broadcast-base-path, which is used to specify base path for temporary storage of broadcast data for presto-on-spark native execution.
  • Remove support for Presto Server RPM.
  • Remove Experimental prefix from Dynamic Filtering.
  • Add support for Hive S3 configuration to Iceberg Hadoop and Nessie catalogs.

Hive Connector Changes

  • Fix a bug where the ParquetWriter throws "Size is greater than maximum int value" error when the table is large.
  • Add Prestissimo support to write Parquet table storage format.
  • Add support for the TTL of Alluxio SDK cache.

JDBC Changes

  • Add cache support for JDBC metadata calls. This can be enabled by configuring parameter metadata-cache-ttl, metadata-cache-refresh-interval and metadata-cache-size.

Native Connector Changes

  • Add TPC-DS tests for native execution based on Parquet files.

Presto on Spark Changes

  • Add optimization to switch the build and probe sides of a join at runtime when a query runs with adaptive execution. This optimizer can be enabled by setting the session property adaptive_join_side_switching_enabeld = true or configuration property optimizer.adaptive-join-side-switching-enabled = true.
