Do you really need a UUID GUID?
UUID’s should be a last resort tactic,employed only after you have exhausted other strategies for determining uniqueness in an architecture. In a database, they are generally considered an anti-pattern and should be avoided due to the performance limitations in indexing their values. UUID’s also not particularly friendly to users. Instead, engineers should use natural keys as much as possible, and auto incremented integers as an alternative (when it makes sense).
