Akka framework (Scala) - Agents to store large complex state

I recently discovered the akka framework and felt it was a good match for one of my projects. I must say I'm very impressed with it so far.

In my project, I need to have 1M+ entities receive state updates a very fast rate. Naturally, akka actors seem to be the first choice. I do however wonder if I'm not better off using agents to store the state updates (so far, my actors only have two messages - one for updating the state and the other for reading it -- and I don't believe that will ever change).

Looking at the few examples for agents, I get the feeling that they are not meant to store large complex state. Am I wrong?

In short, I would like to store something like:

case class AgentState(val list1 : List[Int], val list2 : List[Int], val peers : List[Agent])

Obviously, updating the state becomes less pretty than in toy examples where you use integers ;)

Does it make sense then to have an Agent? How would you go about doing this?

Thanks for your answers!

-LP

Akka Agents are backed by Actors, so it only makes sense if you want to have concurrent readers and serial writers.
