Frequently asked questions
The random UUID() method is used to retrieve a type 4 (pseudo-randomly generated) UUID. The UUID is generated using a cryptographically strong pseudo-random number generator.
UUIDs are generally used for identifying information that needs to be unique within a system or network thereof. Their uniqueness and low probability of being repeated make them useful for being associative keys in databases and identifiers for physical hardware within an organization.
A version 4 UUID is being generated using a timestamp and the MAC address of the computer on which it was generated.
