[jira] [Created] (FLINK-2576) Add outer joins to API and Optimizer
Ricky Pogalz created FLINK-2576:
-----------------------------------
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.
