API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

The DeleteDBInstance action deletes a previously provisioned DB instance. When you delete a DB instance, all automated backups for that instance are deleted and can't be recovered. Manual DB snapshots of the DB instance to be deleted by DeleteDBInstance are not deleted.

If you request a final DB snapshot the status of the Amazon RDS DB instance is deleting until the DB snapshot is created. The API action DescribeDBInstance is used to monitor the status of this operation. The action can't be canceled or reverted once submitted.

Note that when a DB instance is in a failure state and has a status of failed, incompatible-restore, or incompatible-network, you can only delete it when the SkipFinalSnapshot parameter is set to true.

If the specified DB instance is part of an Amazon Aurora DB cluster, you can't delete the DB instance if both of the following conditions are true:

To delete a DB instance in this case, first call the PromoteReadReplicaDBCluster API action to promote the DB cluster so it's no longer a Read Replica. After the promotion completes, then call the DeleteDBInstance API action to delete the final instance in the DB cluster.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to DeleteDBInstanceAsync.
