---------------------------------------

             Summary: Document per-window state in ProcessWindowFunction
                 Key: FLINK-6163
                 URL: https://issues.apache.org/jira/browse/FLINK-6163
             Project: Flink
          Issue Type: Improvement
          Components: DataStream API, Documentation
            Reporter: Aljoscha Krettek
            Priority: Blocker
             Fix For: 1.3.0


The current windowing documentation mostly describes {{WindowFunction}} and treats {{ProcessWindowFunction}} as an afterthought. We should reverse that and also document the new per-key state that is only available to {{ProcessWindowFunction}}.
