How to identify existing actors

When to use AkkaSelection

Basics for actors: https://doc.akka.io/docs/akka/2.5.5/scala/actors.html

PSilvestre commented 5 years ago

Were going to have to use akka cluster to join different machines: https://doc.akka.io/docs/akka/current/cluster-usage.html

This means we can take advantage of Cluster Sharding to spread our actors around. We could possibly go back to the old design of having User PersistentActors, and have these despawn after a timeout.

https://doc.akka.io/docs/akka/current/cluster-sharding.html

EDIT: Looked a bit more into it, with akka-sharding you can setup a Guardian, say UserGuardian, who has two functions, one for identifying the shard a user is in and one for identifying the user itself.

I really think this is the way to go forward, so tomorrow I will go to the library to attempt to implement a prototype. Anyone who wants to join is welcome.

Very good tour through lots of the implementation details and concepts of akka, we need.
