[jira] [Created] (FLINK-3899) Document window processing with Reduce/FoldFunction + WindowFunction

Fabian Hueske created FLINK-3899:
------------------------------------

             Summary: Document window processing with Reduce/FoldFunction + WindowFunction
                 Key: FLINK-3899
                 URL: https://issues.apache.org/jira/browse/FLINK-3899
             Project: Flink
          Issue Type: Improvement
          Components: Documentation, Streaming
    Affects Versions: 1.1.0
            Reporter: Fabian Hueske


The streaming documentation does not describe how windows can be processed with FoldFunction or ReduceFunction and a subsequent WindowFunction. This combination allows for eager window aggregation (only a single element is kept in the window) and access of the Window object, e.g., to have access to the window's start and end time.
