[jira] [Created] (DRILL-3560) Make partition pruning work for directory queries

------------------------------------

             Summary: Make partition pruning work for directory queries
                 Key: DRILL-3560
                 URL: https://issues.apache.org/jira/browse/DRILL-3560
             Project: Apache Drill
          Issue Type: New Feature
          Components: Query Planning & Optimization
    Affects Versions: 1.1.0
            Reporter: Stefán Baxter
            Assignee: Jinfeng Ni


Currently queries that include directory conditions are not optimized at all and the directory expression (dir0 = 'something') is evaluated for every record of every file for every directory.

This could be optimized to fail directories and allow for the same kind of partition pruning for directories as for other scenarios where data has been partitioned.
