Release 0.151

General

  • Fix issue where aggregations may produce the wrong result when task.concurrency is set to 1.
  • Fix query failure when array, map, or row type is used in non-equi JOIN.
  • Fix performance regression for queries using OUTER JOIN.
  • Fix query failure when using the {func}arbitrary aggregation function on integer type.
  • Add various math functions that operate directly on float type.
  • Add flag deprecated.legacy-array-agg to restore legacy {func}array_agg behavior (ignore NULL input). This flag will be removed in a future release.
  • Add support for uncorrelated EXISTS clause.
  • Add {func}cosine_similarity function.
  • Allow Tableau web connector to use catalogs other than hive.

Verifier

  • Add shadow-writes.enabled option which can be used to transform CREATE TABLE AS SELECT queries to write to a temporary table (rather than the originally specified table).

SPI

  • Remove getDataSourceName from ConnectorSplitSource.
  • Remove dataSourceName constructor parameter from FixedSplitSource.

:::{note} This is a backwards incompatible change with the previous connector SPI. If you have written a connector, you will need to update your code before deploying this release. :::
