title: What all happens when we promote a read replica to separate RDS instance?
body: <p>I tried promoting a read replica to a separate RDS instance. It took nearly 10 minutes to complete and during that time. As far as I can think, it should just break the replication process, sync for the time lag. But I saw the db instance getting rebooted also in case of EC2 RDS. Can someone please clearly explain to me the whole process?</p>
