How does Scala support eventual consistency in globally distributed systems?

Scala systems achieve eventual consistency using event logs, replication, and asynchronous propagation across nodes.

Eventual consistency in Scala-based distributed systems is typically implemented using event-driven architectures (Kafka, Akka Persistence, or event sourcing). Each node processes local writes and propagates events asynchronously to other nodes. Conflict resolution strategies like CRDTs or last-write-wins are used. Scala’s immutable data structures ensure deterministic replay, making state reconstruction reliable even after failures or partitions.
