[MonetDB-users] Benefits of sorted columns

Hi, I know that when a table is sorted on a column, value look-ups on that column will use a binary search instead of a linear search. Is there a similar benefit for joins? E.g. if I have 2 tables that contain a sorted column C and I do an equality join on this column (or a self-join using 2 aliases of the same table), I would expect a traditional DBMS to do a merge-join.
