    Description

      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.
