Rong Rong commented on FLINK-11453:
-----------------------------------
Per the discussion of the community, we will move the slicing API from public
API to internal {{WindowedStream}} to {{WindowOperator}} conversion phase.
Closing this JIRA.

> Project: Flink
> Issue Type: Sub-task

> Support slicing operation that produces slicing:
> {code:java}
> val slicedStream: SlicedStream = inputStream
> .keyBy("key")
> .sliceWindow(Time.seconds(5L)) // new “slice window” concept: to
> combine
> // tumble results based on discrete
> // non-overlapping windows.
> .aggregate(aggFunc)
> {code}
> {{SlicedStream}} will produce results that exposes current {{WindowOperator}}
> internal state {{InternalAppendingState<K, W, IN, ACC, ACC>}}, which can be
> later applied with {{WindowFunction}} separately in another operator.
