Gang Tim Liu created HIVE-3642: ---------------------------------- Summary: Hive List Bucketing - optimize transform() Key: HIVE-3642 URL: https://issues.apache.org/jira/browse/HIVE-3642 Project: Hive Issue Type: New Feature Reporter: Gang Tim Liu Priority: Minor
In list bucketing transform(), we create pruning tree for each partition. Although it is possible that different partitions have different skewed keys, chances are that there will be a lot of overlap. It would be a good idea to optimize that case. -- This message is automatically generated by JIRA.
