// 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 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.
