[jira] [Created] (TAJO-966) Range partition should support split of multiple characters.

Hyunsik Choi created TAJO-966:
---------------------------------

             Summary: Range partition should support split of multiple characters.
                 Key: TAJO-966
                 URL: https://issues.apache.org/jira/browse/TAJO-966
             Project: Tajo
          Issue Type: Improvement
          Components: data shuffle
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 0.9.0


Currently, range partition does not support split of multiple characters. As a result, it only consider the first character when Tajo does range partitioning against TEXT or VARCHAR fields. This approach sometimes results in skewed ranges, and it causes performance degradation.

We should fix it.
