Amazon SageMaker now adds support for Custom Attributes

You can now get additional information about the inference request or response in Amazon SageMaker with the latest support. CustomAttributes is a new HTTP header developed for the InvokeEndpoint API action. You can now easily send information by using the CustomAttributes to pass on information to the inference request or response such as application specific identifier, trace ID or other metadata. This will help keep track of the request or responses for audit purpose or tracking metrics. AWS Signature Version 4 authenticates Calls to the InvokeEndPoint API action and it authenticates all inbound API request to AWS services.
