// Deploys the new EndpointConfig specified in the request, switches to using
// newly created endpoint, and then deletes resources provisioned for the endpoint
// using the previous EndpointConfig (there is no availability loss). When
// SageMaker receives the request, it sets the endpoint status to Updating . After
// updating the endpoint, it sets the status to InService . To check the status of
// an endpoint, use the DescribeEndpoint (https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DescribeEndpoint.html)
// API. You must not delete an EndpointConfig in use by an endpoint that is live
// or while the UpdateEndpoint or CreateEndpoint operations are being performed on
// the endpoint. To update an endpoint, you must create a new EndpointConfig . If
// you delete the EndpointConfig of an endpoint that is active or being created or
// updated you may lose visibility into the instance type the endpoint is using.
// The endpoint must be deleted in order to stop incurring charges.
