      • getCachedResponseMetadata

        public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
        Description copied from interface: AmazonQLDB
        Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

        Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

        Specified by:
        getCachedResponseMetadata in interface AmazonQLDB
        Parameters:
        request - The originally executed request.
        Returns:
        The response metadata for the specified request, or null if none is available.
