The source of the database model (using peewee) is included with Prodigy in components/db.py, so you can check out how it is set up there. For 100% flexibility, you can also implement your own custom Database class – see here for more details:

Using Google Firestore as database or not

Prodigy lets you pass in a custom Database class via the "db" setting returned by a custom recipe, or via an entry point of your own Python package installed in the same environment. So basically, you can write a class that exposes the same methods and properties as the built-in Database class but writes to your remote Firestore database. For instance, it’d have a method add_examples that takes a list of examples and a list of one or more dataset names and then adds those examples to the given …

As long as the database methods exist and do the right thing, it's then fully up to you how you implement the logic and how the data is stored or retrieved.
