Yes, we are thinking about it for the future. Semantics for that are not
trivial, so the first version will not do that...
> Add new window API to streaming API
> -----------------------------------
>
> Key: FLINK-2753
> URL: https://issues.apache.org/jira/browse/FLINK-2753
> Project: Flink
> Issue Type: Sub-task
> Components: Streaming
> Affects Versions: 0.10
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Fix For: 0.10
>
>
> The API integration should follow the API design as documented here:
> https://cwiki.apache.org/confluence/display/FLINK/Streams+and+Operations+on+Streams
> This issue needs:
> - Add new {{KeyedWindowDataStream}}, created by calling{{window()}} on the
> {{KeyedDataStream}}.
> - Add a utility that converts Window Policies into concrete window
> implementations. This is important to realize special case implementations
> that do not directly use generic mechanisms implemented by window policies.
> - Instantiating the operators (dedicated and generic) from the window
> policies
> - I will add a stub for the new Window Policy classes, based on the
> existing policy classes.
