What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit label used for information in computer systems. The term globally unique identifier (GUID) is also used, typically in software created by Microsoft.
Versions
- Version 1 (Timestamp-based): Generated from a time and a node id (usually the MAC address);
- Version 4 (Random): Generated using random or pseudo-random numbers.
When to use UUIDs?
UUIDs are useful when you need unique identifiers that can be generated without a central authority or coordination between systems.
