Replication Topology

Replication topology refers to the structure or layout of how data is copied and synchronized across multiple servers or databases. It determines how changes made on one system are propagated to others, ensuring data consistency. Common types include a single master (where one server updates others) or multi-master setups (where multiple servers update each other). This setup affects performance, reliability, and data integrity, and is chosen based on organizational needs for scalability and fault tolerance. Essentially, it’s the plan that coordinates how data flows between systems to keep them all up-to-date.
