Followers are replications of the Leader configured for which purpose?

Followers are read-only replicas of the Leader that perform asynchronous replication from the Leader. This means that they receive updates from the Leader periodically, but not in real time. Followers are designed to handle all types of read requests from workloads and applications, such as authentication, permission checks, and secret fetches. Followers can scale horizontally to support a large number of concurrent requests and reduce the load on the Leader. Followers also provide high availability and disaster recovery by serving as backup nodes in case of Leader failure or network partition. References: Set up Follower, Deploy the Conjur Follower, Follower architecture
