What is a Version-4 UUID?
A Version 4 UUID (Universally Unique Identifier) is a 128-bit label generated randomly. The probability of finding a duplicate (collision) is so vanishingly small that it is virtually zero, making it ideal for primary keys in distributed databases, microservices, and unique session tokens.
