    en.wikipedia.org/wiki/Universally_unique_identifier

    This number would be equivalent to generating 1 billion UUIDs per second for about 86 years. A file containing this many UUIDs, at 16 bytes per UUID, would be about 43.4 exabytes (37.7 EiB ). The smallest number of version-4 UUIDs which must be generated for the probability of finding a collision to be p is approximated by the formula

    It uses a sequence-based hi-lo pattern to generate values. Hi/Lo is used in scenarios where an application needs its entities to have an identity prior to persistence. It is a value generation strategy. An alternative to Hi/Lo would be for the application to generate keys as universally unique identifiers (UUID).
