About UUID v4
A UUID (Universally Unique Identifier) v4 is a 128-bit number generated using random or pseudo-random numbers. Format:
xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx
The 4 indicates version 4. The y is one of 8, 9, a, or b (variant bits). With 2^122 possible values (~5.3 × 10^36), collisions are practically impossible.
