AkkaCluster and AkkaTyped DeepDive Into the ActorModelWith a BitofEyeCandy.

on YouTube ↗01h 59m

" summary

Four Java projects on GitHub (mckeeh3) boot a nine-node local Akka cluster with scripts, a web dashboard eye candy, and progressively add Akka Typed features: receptionist-based peer discovery, a cluster singleton, and cluster sharding with 18 shards. A simulator/twin pair handles ~200k live actors, uses Akka Persistence with Cassandra and Postgres, runs on Kubernetes/AWS, and demonstrates automatic failover, shard relocation, node kill/down, and live dashboards — the examples run and reproduce the behaviors shown.
