In Aurora MySQL 2.10 and higher, Aurora restarts only the writer DB instance and the failover target during a failover. … If the primary instance fails, Amazon RDS promotes the Aurora Replica with the better priority to the new primary instance. You can modify the priority of an Aurora Replica at any time.
