Subject [jira] [Created] (CRUNCH-216) Transpose arguments in MapsideJoinStrategy.join
Date Mon, 10 Jun 2013 07:13:20 GMT
Gabriel Reid created CRUNCH-216:

             Summary: Transpose arguments in MapsideJoinStrategy.join
                 Key: CRUNCH-216
             Project: Crunch
          Issue Type: Improvement
            Reporter: Gabriel Reid

The MapsideJoinStrategy currently specifies that the smaller table in the join (i.e. the table
to be replicated and loaded in memory) should be on the right-hand side of the join.

This is the opposite of what is done in all other join strategies, making it impossible to
just switch out another join strategy for a MapsideJoinStrategy. The MapsideJoinStrategy could
be brought in line with the other JoinStrategies to expect the smaller of two tables to be
provided as the left-side table.
