What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across space and time. UUID v4 uses random or pseudo-random numbers, making it ideal for generating unique IDs in distributed systems without coordination.
UUIDs are commonly used as database primary keys, session tokens, API request IDs, and anywhere a unique identifier is needed. The format is 8-4-4-4-12 hexadecimal digits (e.g., 550e8400-e29b-41d4-a716-446655440000).
