Analyzing New Unique Identifier Formats (UUIDv6, UUIDv7, and UUIDv8)
(scaledcode.com)
I have written before about UUIDs and other unique identifiers. As a reminder UUIDs are 128-bit identifiers that strive for unique identifier generation without requiring the generation to be done in a centralized location. The specification for UUIDs was written in 2005 and is defined in RFC 4122. This specification has served the industry fairly well. Even so there have been many other mechanisms for generating unique identifiers to try to make up for the shortcomings of the original specification.
