Container for the parameters to the PromoteReadReplica operation. Promotes a Read Replica DB instance to a standalone DB instance.

We recommend that you enable automated backups on your Read Replica before promoting the Read Replica. This ensures that no backup is taken during the promotion process. Once the instance is promoted to a primary instance, backups are taken based on your backup settings.
