Cartonnage is a Database-First ORM—designed as a 'Live Database Reflection ORM' or 'Record Reflection Layer (RRL)'—that reflects your existing database at runtime, speaking its schema fluently: not model-first, not schema-first, but runtime-bound, making it the ORM for existing databases.
A simple, flexible, and robust wrapper around the Postgres COPY command. Supports loading CSV/JSON files and Python objects with automatic schema inference.
