UUIDv1 or UUIDv4?

Unless you have a specific reason for using UUIDv1, eg. you wish your UUID provides some indication of the time when it was created, we recommend using UUIDv4.

It would take 85 years generating at a rate of 1 billion UUIDs per second to have a 50% chance of getting a single repeated value using UUIDv4.
