I will show you what UUID types are, how to use them properly and present 3 newly introduced types: v6, v7 and v8 that will help you do all of it right. All in a form of a walk through the history of UUIDs.
And as a bonus, I’ll show you how to not (ab)use them in some unusual ways presenting your my use case of converting a legacy multi-tenant database into a single DB, which forced us to move to UUIDs due to ID conflicts after the merge. Especially that new types really help to do exactly that in a proper way.
All of that in a Python ecosystem and presenting all the UUID types in upcoming changes to the stdlib.
