             Summary: Add outer joins to API and Optimizer
                 Key: FLINK-2576
                 URL: https://issues.apache.org/jira/browse/FLINK-2576
             Project: Flink
          Issue Type: Sub-task
          Components: Java API, Optimizer, Scala API
            Reporter: Ricky Pogalz
            Priority: Minor
             Fix For: pre-apache


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