title: How do I practically use Raft algorithm
body: <p>In the Raft paper, they mentioned that all the client interaction happens with the leader node. What I don't understand is that the leader keeps changing. So let's say my cluster is behind a load balancer. How do I notify the load balancer that the leader has changed? Or if I'm correct, is it that load balancer can send out client request to any of the node (follower or leader) and it is the responsibility of the follower node to send the request to the leader?</p>
