I have developed an end to end example showcasing usage of all of akka famility of frameworks. Its a simple and small movie ticket booking website backed by event sourcing with persistent actors.
The code is at https://github.com/unmeshjoshi/aggregateactors. Not best of the codes, but gives an overview of how all of akka family of frameworks fit together.
I also blogged about microservices API driven by Aggregates thinking in DDD, and how it can be implemented in Akka.
Thought it might useful to people on this group.
