                 Key: HIVE-3073
                 URL: https://issues.apache.org/jira/browse/HIVE-3073
             Project: Hive

          Components: SQL
            Reporter: Gang Tim Liu
            Assignee: Gang Tim Liu


If a hive table column has skewed keys, query performance on non-skewed key is always impacted.
Hive List Bucketing feature will address it:

This jira issue will track DML change for the feature:
1. single skewed column
2. manual load data
