Replication: Strategies and Techniques

This lecture covers the concept of replication in distributed systems, focusing on strategies and techniques to ensure data consistency and availability in the presence of server failures. The instructor explains synchronous and asynchronous replication, discussing the trade-offs between strong consistency and eventual consistency. Various approaches such as primary site replication and peer-to-peer replication are explored, along with the implementation details of the capture and apply steps in replication processes. The lecture also addresses the challenges of conflicts resolution in multi-leader replication scenarios.
