What is a UUID?

A UUID (Universally Unique Identifier) is a 128‑bit value used to uniquely identify objects, sessions, devices, or records. UUIDs are extremely unlikely to collide.

UUID v4 (random)

Generated using cryptographically strong random numbers. Format example: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

UUID v1 (timestamp‑based)

Includes timestamp + random node identifier. Format example: xxxxxxxx-xxxx-1xxx-yxxx-xxxxxxxxxxxx
