13.101. Release 0.161
General Changes
- Fix correctness issue for queries involving multiple nested EXCEPT clauses. A query such as
a EXCEPT (b EXCEPT c)
was incorrectly evaluated as a EXCEPT b EXCEPT c
and thus could return the wrong result. - Fix failure when executing prepared statements that contain parameters in the join criteria.
- Fix failure when describing the output of prepared statements that contain aggregations.
- Fix planning failure when a lambda is used in the context of an aggregation or subquery.
- Fix column resolution rules for
ORDER BY
to match the behavior expected by the SQL standard. This is a change in semantics that breaks backwards compatibility. To ease migration of existing queries, the legacy behavior can be restored by the deprecated.legacy-order-by
config option or the legacy_order_by
session property. - Improve error message when coordinator responds with
403 FORBIDDEN
. - Improve performance for queries containing expressions in the join criteria that reference columns on one side of the join.
- Improve performance of
map_concat()
when one argument is empty. - Remove
/v1/execute
resource. - Add new column to SHOW COLUMNS (and DESCRIBE) to show extra information from connectors.
- Add
map()
to construct an empty MAP.
Hive Connector
- Remove
"Partition Key: "
prefix from column comments and replace it with the new extra information field described above.
JMX Connector
- Add support for escaped commas in
jmx.dump-tables
config property.
