    Frequently asked questions

    What is the difference between UUID v4 and v7?
    UUID v4 is fully random. UUID v7 is time-ordered, so values sort by creation time, which is friendlier to database indexes.
    Are generated UUIDs unique?
    UUIDs are designed so the chance of a collision is negligible in practice, even without coordination between systems.
