Single Master Replication
Single Master Replication is a database replication model where one designated master node handles all write operations, while one or more replica nodes asynchronously copy data from the master to provide read scalability and fault tolerance. This architecture ensures data consistency by centralizing writes, with replicas serving read-only queries to distribute load. It is commonly used in relational databases and distributed systems to improve performance and availability.
Developers should use Single Master Replication when building applications that require high read throughput but have moderate write loads, such as content management systems, e-commerce platforms, or analytics dashboards. It is ideal for scenarios where data consistency is critical, as it avoids write conflicts by funneling all updates through a single source, though it can become a bottleneck under heavy write traffic.
