The Ent Framework: Meta’s Object-Relational Mapping
summary
Meta's Ent framework is an object-relational layer that enforces privacy per load via generated privacy policies, evaluates rules in order, and denies or allows access using a viewer context; it separates read objects from mutations with a strongly typed nql query language and an n mutator, generates code with gen_code, and runs on over 40,000 schemas across 30+ storage types while using a per-viewer cache and clearing caches on writes to stay consistent.
