Hi I don't know whether this question is suitable for this forum, but I take the risk and ask :)
In my understanding the execution model in Spark is very data (flow) stream oriented and specific. Is it difficult to build a control flow logic (like state-machine) outside of the stream specific processings ? It is only way to combine all different type event streams to one big stream and then process it by some own stateful "logic" ? And how to build this logic ? Best Regards, Esa
