Akka Actor Priorities

Akka Actor Priorities

I have an actor-based system that performs periodic, cpu-intensive data
ingests as well as serves RESTful endpoints. I'm using Akka actors to
signal/control the various stages of the ingest process, and Spray (which
is of course built on Akka) to serve my restful endpoints.
My problem is this: When the ingest kicks off it consumes most of the CPU,
starving the RESTful endpoints until its done.
What's the best way to lower the priority of the ingest? Right now the
ingest and the Spray module share the same ActorSystem, but they could be
separated if that helps the solution.
Thanks for any ideas... Greg
