How about using JSON Schema?

How about using json schema and pydantic instead of marshmallow?

Looks like a nice idea. Should increase performance by 2.5 times!

@Skorpeo I tried using pydantic but it looks like the package does not have a good support for polymorphic schemas. For it to work a major refactor of the JSON structure of the policies would be required. You can check out the code at link.

Let me know if you had success in marshaling polymorphic schema with pydantic. Will try using that approach. Thanks!
