Sophie Blee-Goldman updated KAFKA-5636:
---------------------------------------
Description:
We support three windowing types for aggregations in the DSL right now:
* Tumbling windows
* Hopping windows (note: some stream processing tools call these "sliding
windows")
* Session windows
Some users have expressed the need for sliding windows. While we do use sliding
windows for joins, we do not yet support sliding window aggregations in the DSL

We support three windowing types in the DSL right now:

* Hopping windows (note: some stream processing tools call these "sliding

* Session windows
Some users have expressed the need for sliding windows. We already support
sliding windows because they are used for joins, but we don't expose sliding
windows directly through the API/DSL.
Summary: Add Sliding-Window support for Aggregations (was: DSL: allow
sliding windows to be used directly (i.e. not just implicitly when doing joins))
