When processing continuous streams, one is usually interested in continuous answers broken into epochs or periods of time. Usually, the computations one formulates feel more like "compute the average speed per road segment every 5 minutes" than "what is the average speed in this road segment given all the data I've seen?" If you've been doing stream processing for a while, this is not news to you. In fact, you're probably thinking of windowed queries.
