What is a UUID?
A Universally Unique Identifier is a 128-bit label used to identify information. It enables distributed systems to generate unique IDs without central coordination.
Version 4 (Random)
Generated entirely using random numbers. It offers the highest level of collision resistance for general use cases where sorting is not required.
Version 7 (Time-Sortable)
Encodes a timestamp in the first 48 bits, making these IDs strictly time-ordered. This improves database performance by reducing index fragmentation.
