FAQ
How is v7 different from v4?
UUID v7 starts with a timestamp, so new IDs are ordered. This speeds up inserts into database indexes.
Are UUID and GUID the same?
Yes, GUID is Microsoft’s name for UUID.
Can two UUIDs collide?
In theory yes, in practice no: the probability of a v4 collision is negligible.
