The question in my mind is not “why switch to streaming”? The question is, “why isn’t streaming the default?” We know the consequences of the current batched approach. Even though the effects seem minuscule on small data sets, it adds up across requests. To the point where you can see orders of magnitude difference in performance between a batched app and a streaming app. Streaming is also a natural fit for a key/value approach that we know opens up the reduced SQL requests you mentioned, and enables entire classes of problem. If you examine Convirgance examples, you’ll find that there is no productivity cost to adopting streaming. Quite the opposite. Streaming + Key/Value radically reduces the amount of code and skyrockets productivity.
