Hi Vino, unfortunately I can't contribute any opinion on this as I don't yet understand the consequences. I know that in an asynchronous event processing system some operations that might be useful have to be sacrificed for the sake of asynchonisity.
For me Kafka Stream sort of feeling like the cloud-brother of Edgent, it does seem to support groupBy. Would be really cool if some of the formerly active people could at least leave some comments on questions like this. You don't have to actually work on things, but giving us new guys some guidance would be awesome. I don't want to ruin thing you built over years, just because I'm not that into the topic ... yet.

Hi all, Anyone can give some opinion? Chris ? I think we should support some reduce operation(aggregation function, such as max / avg / min sum) for both stream and windowed stream, these features based on the keyBy or groupBy operation.
