Jaehwa Jung created TAJO-1347:
---------------------------------
Summary: 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.
