-- Updates variant weight of one or more variants associated with an
-- existing endpoint, or capacity of one variant associated with an
-- existing endpoint. When it receives the request, SageMaker 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.
