============ Release 0.79 ============ Hive Changes ------------ * Add configuration option ``hive.force-local-scheduling`` and session property ``force_local_scheduling`` to force local scheduling of splits. * Add new experimental optimized RCFile reader. The reader can be enabled by setting the configuration option ``hive.optimized-reader.enabled`` or session property ``optimized_reader_enabled``. General Changes --------------- * Add support for :ref:`unnest`, which can be used as a replacement for the `explode()` function in Hive. * Fix a bug in the scan operator that can cause data to be missed. It currently only affects queries over ``information_schema`` or ``sys`` tables, metadata queries such as ``SHOW PARTITIONS`` and connectors that implement the ``ConnectorPageSource`` interface.
