What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across all devices and time. UUIDs are used in software development to create unique identifiers for database records, API keys, session tokens, and more.

Version 4 UUIDs are generated using random numbers, making them ideal for general-purpose identification. Version 7 UUIDs include a timestamp component, making them suitable for database primary keys where ordering by creation time is beneficial.
