// For more information about query components, see the [Query Components] section in the Config
// Developer Guide.

// the Limit query parameters, the default page size is set to 500.

// function; e.g., SELECT * WHERE resourceType = 'AWS::IAM::Role' ) and do not
// specify the MaxResults or the Limit query parameters, the default page size is
