Improvements
- Added the session variable hive_partition_stats_sample_size to control the number of Hive partitions from which to collect statistics. An excessive number of partitions will cause errors in obtaining Hive metadata. #12700
- Elasticsearch external tables support custom time zones. #12662
Bug Fixes
The following bugs are fixed:
- The DECOMMISSION operation is stuck if an error occurs during metadata synchronization for external tables. #12369
- Compaction crashes if a column that is newly added is deleted. #12907
- SHOW CREATE VIEW does not display the comments that were added when creating the view. #4163
- Memory leak in Java UDF may cause OOM. #12418
Behavior Changes
Extended the length of Hive STRING columns that can be queried by StarRocks from 64 KB to 1 MB. If a STRING column exceeds 1 MB, it will be processed as a null column during queries. #12986
