Questions fréquentes
What is the advantage of UUID v7 over UUID v4?
UUID v4 is completely random, which causes database index fragmentation as new records are inserted at random positions in the B-tree. UUID v7 is time-sorted, so new records always append to the end of the index, maintaining sequential insert performance similar to auto-incrementing integers while preserving the distributed generation benefits of UUIDs.
