Fabian Hueske created FLINK-2106:
------------------------------------

             Summary: Add outer joins to API, Optimizer, and Runtime
                 Key: FLINK-2106
                 URL: https://issues.apache.org/jira/browse/FLINK-2106
             Project: Flink
          Issue Type: Sub-task
          Components: Java API, Local Runtime, Optimizer, Scala API
            Reporter: Fabian Hueske
            Priority: Minor


Add left/right/full outer join methods to the DataSet APIs (Java, Scala), to the optimizer, and the runtime of Flink.

Initially, the execution strategy should be a sort-merge outer join (FLINK-2105) but can later be extended to hash joins for left/right outer joins.
