Demo: Surviving the Split

Akka handles split-brain scenarios in distributed systems through event sourcing and version vectors, enabling fine-grained conflict resolution at the entity level. When a region fails during multi-region deployment, the system preserves all events in immutable journals, allowing deterministic merge operations that favor the surviving region's timeline while maintaining a complete audit trail. This approach avoids traditional disaster recovery pitfalls like point-in-time rollbacks that affect unrelated data, instead resolving conflicts only for affected entities while keeping discarded events available for compensating actions.
