Description

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.
