Hi Endre, Thank you again and I am trying the code out. I had another quick question though - how do you release and actor reference if the specific request is ALL done? For example let's say that the Result Processor has finished all the work for the 3 data points (R1, R2, R3) and we do not have to hold this hash mapping anymore - how do I release that hash mapping? Does AKKA automatically release resources and assign that actor to another request? How is that taken care of?
I apologize in advance if my wording of the question is off.
