How does Scala support multi-region data replication with conflict-free replication strategies?

Scala uses CRDTs, asynchronous replication, and conflict resolution policies for multi-region consistency.

Multi-region systems replicate data asynchronously using logs or database replication layers. Scala systems often adopt CRDTs (Conflict-Free Replicated Data Types) to ensure safe convergence without coordination. In cases where CRDTs are not applicable, application-level conflict resolution (timestamps, version vectors) is used. This allows high availability even under network partitions.
