title: How can I test failovers in Amazon Aurora DB?
body: <p>By "realistically," I mean that I would expect, in a real world scenario, that when a failover occurs from the primary instance to a replica, the (now ex) primary instance is unusable for whatever reason caused the failover in the first place, and it would be disposed of. That raises a few questions: </p>
  
  <ol>
  <li>If an (ex) primary instance is disposed of, an existing replica is promoted to be the new primary. Does a new replica get created as well since you now have n - 1 replica instances? </li>
  <li>If any of my assumptions are correct, is there a way to test this where the primary instance actually fails and is disposed of, since the "failover" function in RDS just switches it to a replica? </li>
  </ol>
