> Project: Beam
> Issue Type: Wish
> Components: beam-model
> Reporter: Ben Chambers
> Priority: P3
>
> For example, even if the elements are being processed in fixed windows of an
> hour, it may be desirable for the state to "roll over" between windows (or be
> available to all windows).
> It will also be necessary to figure out when this state should be deleted
> (TTL? maximum retention?)
> Another problem is how to deal with out of order data. If data comes in from
> the 10:00 AM window, should its state changes be visible to the data in the
> 9:00 AM window?
