Piotr Nowojski created FLINK-16317:
--------------------------------------

             Summary: Implement missing features for MultipleInputStreamOperator
                 Key: FLINK-16317
                 URL: https://issues.apache.org/jira/browse/FLINK-16317
             Project: Flink
          Issue Type: Sub-task
          Components: API / DataStream, Runtime / Task
    Affects Versions: 1.10.0
            Reporter: Piotr Nowojski
             Fix For: 1.11.0


After https://issues.apache.org/jira/browse/FLINK-16060 support for {{MultipleInputStreamOperator}} is incomplete. After defining new base class for the {{StreamOperator}} (FLINK-15687) that would be suitable to use with {{MultipleInputStreamOperator}}, we can provide support for missing features in the {{MultipleInputStreamOperator}}, like:
* keyed state support
* processing {{Watermark}}
* processing {{LatencyMarker}}
* {{StreamStatus}}
* input selection
