About UUID v4
UUID v4 (Universally Unique Identifier version 4) is generated using random or pseudo-random numbers. The format is xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx where 4 indicates the version and y is one of 8, 9, a, b. There are 2122 possible UUIDs (~5.3 × 1036), making collisions virtually impossible. UUIDs are widely used as database primary keys, session tokens, correlation IDs, and distributed system identifiers.
