--------------------------------------

             Summary: Change return type of JoinFactory::create*Join()
                 Key: OPTIQ-396
                 URL: https://issues.apache.org/jira/browse/OPTIQ-396
             Project: Optiq
          Issue Type: Task
            Reporter: Ashutosh Chauhan
            Assignee: Ashutosh Chauhan


This provides tighter type checking than RelNode and is consistent with 
RelFieldTrimmer, only consumer of this factory which assumes these nodes to be 
of type {{JoinRelBase}}
