> 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.
