How does Scala support distributed state management?

Scala manages distributed state using event sourcing, cluster sharding, and external state stores.

Distributed state is one of the hardest problems in system design. Scala solves it using Akka Cluster Sharding to partition stateful actors across nodes. Event sourcing ensures state can be reconstructed from logs. External stores like Cassandra or Redis are used for persistence. Consistency models vary between eventual and strong consistency depending on requirements.
