Hi can somebody help me understand how cache usage is affected when we use caveats in spiceDB. For example if we have an expression permission a = (combination of other permission) & caveat What part is cached? Will the Boolean exp part (combination of other permission) Be cached? Is there any caching of caveat? Are other permission that don't use caveat cached? I have hard time understanding this...

caveats are designed leverage SpiceDB's distributed caching layer. SpiceDB caches the caveat expressions themselves, so that it can instantly determine what needs to be executed for a particular request. With this, our goal to maintaining properties of scale and latency is met for schemas using caveats.

This is from authzed docs

so one thing is that a caveat is always a part of a relation
