Since Pike we've generated the templates for various nested stack resource types with outputs that produce the attribute values that are referenced in the parent stack, and a previous patch did the same for resource IDs. Use these output values when available to calculate the attribute values. This is efficient, because the all of the outputs are fetched together and cached, and avoids using the grouputils functions that cause the nested stack to get loaded into memory in the same process. Fall back to the existing implementation (using grouputils) if the required output isn't available (generally this would be due to the nested stack being created on an earlier version of Heat that did not include the outputs in the generated template, and not updated since).

Heat
Heat is a service to orchestrate multiple composite cloud applications using templates, through both an OpenStack-native REST API and a CloudFormation-compatible Query API.
Why heat? It makes the clouds rise and keeps them there.
