Cluster Sharding scales stateful domain entities across a cluster with minimal plumbing. This guide covers requirements, minimal design, trust boundaries, operational checks, failure modes, and when to adjust the design, with a Cassandra‑backed example.
A child actor crashes mid-message. Should you Resume, Restart, Stop, or Escalate? Learn how to pick an Akka SupervisorStrategy based on state consistency, not just uptime.
Akka Cluster Sharding lets you route commands to thousands of stateful actors across a cluster. Learn how to set up a typed shard region, a counter entity example, and the trade‑offs of rebalancing, passivation, and licensing.
Decide between no persistence, EventSourcedBehavior, and DurableStateBehavior for Akka actors based on auditability, recovery cost, and storage constraints, with a testkit-based validation path.
A diagnostic guide for Akka Cluster Sharding entities that never receive messages: registration gaps, passivation recovery failures, serializer mismatches, and how to verify each fix.
Learn how Akka Typed Actors enforce message contracts at compile time, reducing runtime casts and making actor‑based systems safer to refactor.
Step‑by‑step guide to deploy Akka Cluster Sharding with typed persistence, including configuration, verification, and recovery procedures.
Learn how Akka Typed Actors replace unsafe runtime casts with compile‑time message safety, using a simple echo actor example and practical migration tips.
Learn how to define a type‑safe protocol, implement a Typed Actor, and use the Ask pattern for request‑response with Akka in Scala, including verification and recovery techniques.
