Zio Actors
summary
ZIO-Actors is a small, strongly typed actor library built on ZIO that produces an ActorSystem as a Task and spawns actors with unique names and typed state/command/response signatures. It implements supervision via ZIO Schedules (examples include exponential retry up to 10), guarantees per-pair message ordering, offers remoting over hostname/port using Java NIO selectors, and uses Java serialization initially while moving toward a ZIO serialization solution. Persistence exists as a first iteration with persistence with Postgres via Doobie and in-memory backends (no snapshotting yet). Examples include a persistent counter and an FSM that fails to trigger recovery.
