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

             Summary: 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.
