Nice video. I have a question about the scenario where you would use replication for disaster recovery. Suppose you have one source running on machine A and one replica running on machine B. The purpose of the replica is failure backup for failures on machine A. Now suppose that happens (i.e., machine A is down), then what are the steps to be taken? I assume that somehow the replica must be upgraded so it allows writing? But what would be the easiest way of handling this in MySQL? Thanks in advance for any explanation on this :)
