Read Replicas

Read replicas are copies of a database that are synchronized with the original database, called the primary or master. They allow multiple users or applications to perform read-only operations, such as viewing or querying data, without impacting the performance of the main database. This setup helps distribute the workload, improve response times, and enhance availability. Think of a read replica as a mirror that reflects the main database’s data, enabling efficient access without risking the stability or speed of the primary database. They are essential for managing large-scale applications and ensuring smooth data flow.
