Learning Concurrent Programming in Scala

Summary

In this chapter, we learned what actors are and how to use them to build concurrent programs. Using the Akka actor framework, we studied how to create actors, organize them into hierarchies, manage their life cycle, and recover them from errors. We examined important patterns in actor communication and learned how to model actor behavior. Finally, we saw how the actor model can ensure location transparency, and serve as a powerful tool to seamlessly build distributed systems.

Still, there are many Akka features that we omitted in this chapter. Akka comes with a detailed online documentation, which is one of the best sources of information on Akka. To obtain an in-depth understanding of distributed programming, we recommend the books Distributed ...
