# Release 0.144#

Warning

Querying bucketed tables in the Hive connector may produce incorrect results. This is fixed in Release 0.144.1, and Release 0.145.

## General Changes#

• Fix already exists check when adding a column to be case-insensitive.

• Fix correctness issue when complex grouping operations have a partitioned source.

• Fix missing coercion when using INSERT with NULL literals.

• Fix regression that the queries fail when aggregation functions present in AT TIME ZONE.

• Fix potential memory starvation when a query is run with resource_overcommit=true.

• Queries run with resource_overcommit=true may now be killed before they reach query.max-memory if the cluster is low on memory.

• Discard output stage JSON from completion event when it is very long. This limit can be configured with event.max-output-stage-size.

• Add support for EXPLAIN ANALYZE.

• Change infoUri field of /v1/statement to point to query HTML page instead of JSON.

• Improve performance when processing results in CLI and JDBC driver.

• Improve performance of GROUP BY queries.

## Hive Changes#

• Add support for creating and inserting into bucketed tables.
