If the column which has been used for partitioning is used as part of a distinct () operation Firewater should push down the distinct() operation to the remote nodes. Will require model changes to allow Firewater to know which is the partitioned column (columns?) during table definition and rewrite rules allow for the distinct to be pushed to remotes.
