Returns a random universally unique identifier (UUID), sometimes called a globally unique identified (GUID). It is represented as 32 hexadecimal (base 16) digits displayed in five groups separated by hyphens.
Use this when you need to assign a unique ID, such as a tracking number for a transaction. This is the same algorithm we use to assign unique IDs to each Flow execution and to each new row in a table.
The algorithm to generate the random UUID is RFC 4122 version 4. According Wikipedia, "the probability to find a duplicate within 103 trillion version 4 UUIDs is one in a billion."
