What is a UUID?

UUID (Universally Unique Identifier) is a 128-bit identifier that is designed to be unique across space and time. UUIDs are commonly used in software development for generating unique identifiers for database records, API endpoints, file names, and more. The most common version is UUID v4, which uses random or pseudo-random numbers.
