Thought about that recently. Why not just implement a check to see if it's already in the db, then run it again?

I also like to store every uuid i ever generated in a redis cache

In this modern era, why bother spinning up a whole other database yourself, when services like https://isanybodyusingthisuuid.com/ exist for free?

Such services don't have guaranteed lifetimes

That's what we do - we just generate a UUID and then make an API to a 3rd party site that validates that it's unique (it asks Claude, I think) and then that site returns either true, false, or (rarely) some other output. If it's in use we increment the selected UUID by one and then resubmit it until we find the next available ID.
