TemplateResources can have their reference ID defined by an OS::stack_id output in the template. However getting it - or just checking that it even exists - is very expensive, and it happens virtually every time we load the stack in memory for any reason. Since when the output is present the reference ID is also available as an attribute, simply cache it in the database as if it were an attribute regardless of whether the output exists. Once it is in the cache, subsequent accesses will be cheap just like they are for attributes. Keep previous performance optimisations in place as well, since attributes are not stored in the database in the legacy path (so legacy stacks don't benefit from this change), and since the cache does get invalidated e.g. on every stack update.

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.
