Hello!
Thank you for making this source code available, it's very useful, i'm studying akka and searching for patterns, best practices and ways of doing things, and i have a doubt based on this implementation.
How it's supposed to scale? Since it creates a new Actor for each issue, if a have billions of issues, how can i scale it?
Currently, all events are replayed when state of an issue is recovered. In real world application, this could make a significant impact on performances. Introduce snapshots so that state recovery can be performed as fast as possible.
Consider to get rid of the PersistentFSM in favor to plain PersistentActor
