-------------------------------
Resolution: Duplicate
> Apply column partitions to query optimizer.
> -------------------------------------------
>
> Key: TAJO-1347
> URL: https://issues.apache.org/jira/browse/TAJO-1347
> Project: Tajo
> Issue Type: Sub-task
> Components: Planner/Optimizer
> Reporter: Jaehwa Jung
> Assignee: Jaehwa Jung
>
> After TAJO-1284, CatalogStore will be aware of partition lists for each
> table. If users write filters for their query, Tajo will find corresponding
> partitions to the filers. This means that Tajo doesn't need to scan full HDFS
> directories. If Tajo support this feature, Tajo can scan column partitioned
> table more faster.
