UUIDs are of a fixed size (128 bits) which is reasonably smallĬompared to other alternatives. Necessary, so that they could even be used as transaction IDs. High allocation rates of up to 10 million per second per machine if The UUID generation algorithm described here supports very On demand can be completely automated, and used for a variety of IEEE 802 node identifiers, others do not). One of the main reasons for using UUIDs is that no centralizedĪuthority is required to administer them (although one format uses RFC 4122 A UUID URN Namespace July 2005 2.
