Advanced Akka features
summary
Live demo of Akka features shows a seven-node Raspberry Pi cluster and a JVM setup with two seed nodes (ports 2551/2552), sending about 10,000 messages through a router that uses round-robin and load-based pools, proving near-even distribution. Covers remote actors (same API for local/remote), scheduled and periodic messaging, cluster singleton failover, sharding for partitioned load, and persistence with a journal plus snapshots and journal replay to recover state. Akka HTTP exposes actor functionality to the outside world.
