Github user senorcarbone commented on the pull request:

    From a quick read on the documentation (and prior knowledge from google dataflow) it is
easy to get a full picture of the new semantics. Even though I like it from a engineering
perspective, It needs to be pointed out though that the addition of the *Assigner* restricts
our previous windowing semantics to periodic windows, i.e. at the moment you receive a record
you have to know all the possible buckets this record will fall into while before we did not
have such a constraint. In other words we no longer support dynamic windows where range and
slide can change dynamically.
