Overview

This module defines a set of methods useful for eliminating N+1 query problem during the serialization. Serializers will first prepare a tree of “promises” for every nested lazy relationship. The relationship promises will be evaluated only when they’re requested. E.g. when including ‘comments.user`: instead of loading a user for each comment separately it’ll gather the comments and load all their users at once when including the users in the response.
