> 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
