- When should I use uuid. uuid1 () vs. uuid. uuid4 () in python?
Here is an alternative approach to UUID Though the chance of collision is infinitesimal UUID doesn't guarantee uniqueness To guarantee the uniqueness you may want to use compound key as [<system id>,<local id>] Each system participating in data sharing must have its own unique ID of the system either assigned during system set-up or obtained from a common pool of IDs Local id is a unique
