What is UUID?
UUID (Universally Unique Identifier) is a 128-bit identifier standardized by RFC 4122. The format is xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where the 4 digit indicates the version and y indicates the variant.
UUIDs v4 are generated with random bytes, ensuring astronomically low probability of collision. They are widely used as primary keys in databases, session identifiers and API tokens.
