DeleteDBInstance Method (deleteDBInstanceRequest)
AmazonAmazon.RDSAmazonRDSDeleteDBInstance(DeleteDBInstanceRequest) Did this page help you?   Yes   No    Tell us about it...

The DeleteDBInstance action deletes a previously provisioned DB instance. A successful response from the web service indicates the request was received correctly. When you delete a DB instance, all automated backups for that instance are deleted and cannot be recovered. Manual DB snapshots of the DB instance to be deleted are not deleted.

If a final DB snapshot is requested the status of the RDS instance will be "deleting" until the DB snapshot is created. The API action DescribeDBInstance is used to monitor the status of this operation. The action cannot be canceled or reverted once submitted.
