NOTE

1.9 Distributed Consistency

1. What Is Distributed Consistency - Data remains consistent across multiple replicas, that is, data consistency. 2. Why Distributed Consistency Is Needed - In a distributed environment, the same data needs to be replicated to multiple nodes for fault tolerance. Because replication is delayed by network problems, the same data may differ across multiple nodes at the same moment. Distributed consistency exists to solve this problem.
