>                 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.
