UUIDs in Practice — When Auto-Increment Falls Short
The article discusses the limitations of using auto-increment IDs in databases, particularly in complex systems with multiple writers. It highlights the advantages of UUIDs, which can be generated without coordination and have a low probability of collision. The author suggests that while UUIDs have some trade-offs, they are often a better choice for modern applications.
- ▪Auto-increment IDs work well for simple, single-writer applications but can create bottlenecks in distributed systems.
- ▪UUID v4 is recommended for its low collision probability and ability to work in offline scenarios.
- ▪While UUIDs have a larger storage overhead and can fragment indexes, they are suitable for most projects.

It works — until it doesn't. The Case for Auto-Increment Auto-increment integers are fast, small (4 bytes), and naturally ordered. For a single-database app with one writer, they're perfect.
