📖 UUID Guide & Best Practices
🔍 UUID Structure
Understanding the anatomy of UUID identifiers.
- 128-bit (16 byte) identifier
- 32 hexadecimal digits
- 5 groups separated by hyphens
- Format: 8-4-4-4-12 characters
- Case-insensitive representation
📋 Version Differences
Choosing the right UUID version for your needs.
- v1: Time-based with MAC address
- v4: Pseudo-random generation
- v1 guarantees temporal ordering
- v4 provides better privacy
- v4 is most commonly used
⚡ Performance Considerations
Optimizing UUID usage for performance.
- Database indexing strategies
- Storage overhead (16 vs 4 bytes)
- Comparison performance
- Memory usage considerations
- Network bandwidth impact
🔒 Security Best Practices
Secure implementation of UUID systems.
- Use cryptographically secure randomness
- Avoid exposing internal structure
- Consider enumeration attacks
- Validate input UUIDs properly
- Use appropriate UUID versions
🌐 Cross-Platform Compatibility
Ensuring UUID compatibility across systems.
- Standard RFC 4122 compliance
- Endianness considerations
- String format consistency
- Database storage formats
- Programming language support
🛠️ Implementation Tips
Practical advice for UUID implementation.
- Use native UUID types when available
- Implement proper validation logic
- Consider bulk generation for performance
- Cache frequently used UUIDs
- Monitor collision rates (very rare)
