UUID
GENERATOR
Bulk generation of Universally Unique Identifiers (RFC 4122).
Technical Specification // UUID Overview
A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. While the probability of a duplicate UUID is not zero, it is close enough to zero to be negligible.
UUID Version 4 (Random): This is the most common version. It is generated using random numbers. The number of possible v4 UUIDs is approximately 3.4 × 10^38, making it statistically impossible to generate the same ID twice in most distributed applications.
UUID Version 1 (Timestamp): v1 is generated from a combination of the host network address (MAC address) and the current timestamp. It is useful when you need identifiers that are sortable by time.
Use Cases & Implementation
- > Primary keys for Distributed Databases (PostgreSQL, MongoDB)
- > Session tracking and Transaction IDs in Microservices
- > Filenames for secure cloud storage uploads
- > Non-predictable resource identifiers in REST APIs
