Fix query failure in aggregation spilling (#10587).
Remove support for SHOWPARTITIONS statement.
Improve support for correlated subqueries containing equality predicates.
Improve performance of correlated EXISTS subqueries.
Limit the number of grouping sets in a GROUPBY clause.
The default limit is 2048 and can be set via the analyzer.max-grouping-sets
configuration property or the max_grouping_sets session property.
Allow coercion between row types regardless of field names.
Previously, a row type is coercible to another only if the field name in the source type
matches the target type, or when target type has anonymous field name.
Increase default value for experimental.filter-and-project-min-output-page-size to 500kB.
Improve performance of equals operator on array(bigint) and array(double) types.
Respect X-Forwarded-Proto header in client protocol responses.
Add support for column-level access control.
Connectors have not yet been updated to take advantage of this support.
Add support for correlated subqueries with correlated OR predicates.
Fix optimized ORC writer encoding of TIMESTAMP before 1970-01-01. Previously, the
written value was off by one second.
Fix query failure when a Hive bucket has no splits. This commonly happens when a
predicate filters some buckets out entirely.
Remove the hive.bucket-writing config property.
Add support for creating and writing bucketed sorted tables. The list of
sorting columns may be specified using the sorted_by table property.
Writing to sorted tables can be disabled using the hive.sorted-writing
config property or the sorted_writing_enabled session property. The
maximum number of temporary files for can be controlled using the
Collect and store basic table statistics (rowCount, fileCount, rawDataSize,
totalSize) when writing.
Add hive.orc.tiny-stripe-threshold config property and orc_tiny_stripe_threshold
session property to control the stripe/file size threshold when ORC reader decides to
read multiple consecutive stripes or entire fires at once. Previously, this feature
piggybacks on other properties.
Add peak memory usage to --debug output.
Make PageSorter and PageIndexer supported interfaces.
