Row-Based Replication
Row-Based Replication (RBR) is a database replication method that logs and replicates individual row changes (inserts, updates, deletes) from a source database to one or more replica databases. It captures the actual data modifications at the row level, making it more precise for certain operations compared to statement-based replication. This approach is commonly used in systems like MySQL, PostgreSQL, and other relational databases to ensure data consistency across distributed environments.
Developers should use Row-Based Replication when they need accurate replication of data changes, especially for operations involving non-deterministic functions, triggers, or stored procedures, as it avoids issues with statement-based replication. It is ideal for scenarios requiring high data integrity, such as financial applications, audit trails, or systems with complex data dependencies, and when replicating between different database versions or configurations where SQL statements might behave differently.
