Drools rules engine with Akka

[Birju]

We're looking at integrating drools into existing Scala, Play framework application. I am not an drools expert but from using it years before I remember drools rules file (if it becomes of significant size) is a real memory hogger (since drools loads it into the memory). Also going traditional Java style (in using drools) is a very synchronous in nature. I am seeking better ways to integrate drools and use it in our Scala, Play framework environment. Can Akka Actors be used to serve better performing drools? Any pointers will be appreciated.

Thanks,
