Subject [GitHub] flink pull request: [FLINK-1328] Reworked semantic annotations
Date Sat, 17 Jan 2015 11:34:46 GMT

    Another question: Would it make sense to annotate the `DefaultFlatJoinFunction` in `JoinOperator.java`.
    We know for sure that the function is going to do. Right now, the optimizer doesn't know
