Frequently asked questions
What is the difference between UUID v4 and v7?
v4 is entirely random. v7 begins with a timestamp, so v7 values sort chronologically, which keeps database indexes far more efficient.
Are the UUIDs unique?
They are generated with secure randomness, making a collision so unlikely it can be disregarded in practice.
