What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value written as 32 hexadecimal digits in five groups, such as 3f2b8c1e-7a4d-4e9b-9c21-5d0f6a8b2e71. Microsoft calls the same thing a GUID.
Version 4 UUIDs are made from 122 random bits, so the chance of two ever matching is so small that they can be created anywhere without checking a central list. They are widely used as database keys, file names and request IDs.
