YugabyteDB allows users to enable low-latency reads from their primary cluster by using follower reads, which allow applications to read from replicas that are closer to the client, reducing latency without adding servers via read replicas. This method is suitable for applications that do not require the latest data or are working with unchanging data. Follower reads execute on the primary cluster and provide better latency than traditional read replicas but may still result in stale reads due to asynchronous replication from the leader.
