Big fan here!
I've been following the space since a bit of time, and I must say it's exciting. To me this is the future of apps where the Truth lives server-side, and everything reacts from there; With partial state evaluation lowering resource consumption to a minimum.
Kafka Streams and Apache Flink seem to be focused on real-time analytics, and I wish they'd get there to stimulate the space.
