Eric, In your approach, the master is pushing work towards the workers whereas in the other approach the workers are pulling work (technically its still a push, but only after readiness has been signaled). The pull based approach might be advantageous if the work is not evenly distributed, e.g. because some messages need more time to be handled or the worker machines differ largely in capacity.
Hoping this helps. Heiko On Wed, May 28, 2014 at 12:22 AM, Eric Nelson <[email protected]>wrote: > Hi all. I have a question based on the Activator template "akka > distributed workers".
