<ul><li>As a system grows, read operations can overload the database, prompting the need for read replicas to offload the load.</li><li>Read replicas are copies of the primary database dedicated to serving read traffic, reducing the pressure on the main database and increasing read capacity.</li><li>However, implementing read replicas introduces replication lag, which can result in users seeing slightly outdated data during synchronization.</li><li>Proper management of replication lag, intelligent routing of requests, and preparedness for failover are key to leveraging read replicas efficiently.</li></ul>
