API Gateway caching can be enabled and configured to allow for better response times on request processing. When enabled for a stage, caching will be available for the GET method by default; it is recommended that this setting is not changed, however there are other methods available by setting an override. For more information on stage caching, see the AWS API Gateway documentation.
