11.28. Release 0.202
General Changes
- Fix correctness issue for queries involving aggregations over the result of an outer join (#10592).
- Fix
map()
to raise an error on duplicate keys rather than silently producing a corrupted map. - Fix
map_from_entries()
to raise an error when input array contains a null
entry. - Fix out-of-memory error for bucketed execution by scheduling new splits on the same worker asthe recently finished one.
- Fix query failure when performing a
GROUP BY
on json
or ipaddress
types. - Fix correctness issue in
line_locate_point()
, ST_IsValid()
, and geometry_invalid_reason()
functions to not return values outside of the expected range. - Fix failure in
geometry_to_bing_tiles()
and ST_NumPoints()
functions whenprocessing geometry collections. - Fix query failure in aggregation spilling (#10587).
- Remove support for
SHOW PARTITIONS
statement. - Improve support for correlated subqueries containing equality predicates.
- Improve performance of correlated
EXISTS
subqueries. - Limit the number of grouping sets in a
GROUP BY
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 typematches 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. - Add
multimap_from_entries()
function. - Add
bing_tiles_around()
, ST_NumGeometries()
, ST_GeometryN()
, and ST_ConvexHull()
geospatial functions. - Add
wilson_interval_lower()
and wilson_interval_upper()
functions. - Add
IS DISTINCT FROM
for json
and ipaddress
type.
Hive Changes
- Fix optimized ORC writer encoding of
TIMESTAMP
before 1970-01-01
. Previously, thewritten value was off by one second. - Fix query failure when a Hive bucket has no splits. This commonly happens when apredicate filters some buckets out entirely.
- Remove the
hive.bucket-writing
config property. - Add support for creating and writing bucketed sorted tables. The list ofsorting 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. Themaximum number of temporary files for can be controlled using thehive.max-sort-files-per-bucket
property. - 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 toread multiple consecutive stripes or entire fires at once. Previously, this featurepiggybacks on other properties.
CLI Changes
- Add peak memory usage to
—debug
output.
SPI Changes
- Make
PageSorter
and PageIndexer
supported interfaces.
