About UUIDs

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit label used to uniquely identify information in computer systems. The probability of collision is extremely low, making them ideal for distributed systems.

UUID Versions:

UUID v4: Generated using random numbers. Most widely used.
UUID v1: Based on timestamp and MAC address. Sortable by creation time.
NIL UUID: Special UUID with all bits set to zero (00000000-0000-0000-0000-000000000000).

Common Use Cases:

Database primary keys
Session identifiers
File naming
Distributed systems
API request tracking
