> 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.
