Statement-Based Replication
Statement-Based Replication (SBR) is a database replication method where SQL statements executed on a primary server are logged and replayed on replica servers to maintain data consistency. It works by recording each data-modifying statement (like INSERT, UPDATE, DELETE) in a binary log, which replicas then execute to mirror changes. This approach is commonly used in relational database systems like MySQL for replicating data across multiple instances.
Developers should learn SBR when working with MySQL or similar databases that support it, as it's useful for scaling read operations, creating backups, and distributing data geographically. It's particularly effective for simple workloads with deterministic SQL statements, but may not be suitable for complex queries involving non-deterministic functions or stored procedures, where Row-Based Replication might be preferred.
