20.39. Release 0.210

General Changes

  • Fix planning failure when aliasing columns of tables containing hidden columns (#11385).

  • Fix correctness issue when GROUP BY DISTINCT terms contain references to the same column using different syntactic forms (#11120).

  • Fix failures when querying information_schema tables using capitalized names.

  • Improve performance when converting between ROW types.

  • Remove user CPU time tracking as introduces non-trivial overhead.

  • Select join distribution type automatically for queries involving outer joins.

Hive Connector Changes

  • Fix a security bug introduced in 0.209 when using hive.security=file, which would allow any user to create, drop, or rename schemas.

  • Prevent ORC writer from writing stripes larger than the max configured size when converting a highly dictionary compressed column to direct encoding.

  • Support creating Avro tables with a custom schema using the avro_schema_url table property.

  • Support backward compatible Avro schema evolution.

  • Support cross-realm Kerberos authentication for HDFS and Hive Metastore.

JDBC Driver Changes

  • Deallocate prepared statement when PreparedStatement is closed. Previously, Connection became unusable after many prepared statements were created.

  • Remove getUserTimeMillis() from QueryStats and StageStats.

SPI Changes

  • SystemAccessControl.checkCanSetUser() now takes an Optional<Principal> rather than a nullable Principal.

  • Rename connectorId to catalogName in ConnectorFactory, QueryInputMetadata, and QueryOutputMetadata.

  • Pass ConnectorTransactionHandle to ConnectorAccessControl.checkCanSetCatalogSessionProperty().

  • Remove getUserTime() from SplitStatistics (referenced in SplitCompletedEvent).

Note

These are backwards incompatible changes with the previous SPI. If you have written a plugin, you will need to update your code before deploying this release.
