Implement user API keys with Supabase

Rationale

JWTs are at the heart of Supabase authorization, but sometimes we wanna build an app that also gives users access via API keys; or perhaps only exclusively via API keys. As you may know, using JWTs as API keys makes them difficult to revoke and therefore a security issue.

We also want to ensure this doesn't significantly add to RLS polices, if at all.

Finally, we'd love to have this handled by Supabase and do as little as possible in our framework. This simplifies our code and reduces third-party libraries.

A Few Useful Things to Know about Machine Learning

The paper presents some key lessons and "folk wisdom" that machine learning researchers and practitioners have learnt from experience and which are hard to find in textbooks.

1. Learning = Representation + Evaluation + Optimization

All machine learning algorithms have three components:

• Representation for a learner is the set if classifiers/functions that can be possibly learnt. This set is called hypothesis space. If a function is not in hypothesis space, it can not be learnt.
• Evaluation function tells how good the machine learning model is.
• Optimisation is the method to search for the most optimal learning model.
