[jira] [Created] (FLINK-7404) Table API batch join code-gen's equi-join conditions

Fabian Hueske created FLINK-7404:
------------------------------------

             Summary: Table API batch join code-gen's equi-join conditions
                 Key: FLINK-7404
                 URL: https://issues.apache.org/jira/browse/FLINK-7404
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
    Affects Versions: 1.3.2, 1.4.0
            Reporter: Fabian Hueske
            Assignee: Fabian Hueske


{{DataSetJoin}} generates code to evaluate equi-join conditions. However, these conditions are already evaluated by the DataSet join.

Hence, the generated conditions result in unnecessary overhead.
