What Is UUID v7?
UUID v7 is a time-ordered UUID format defined by RFC 9562. It combines sortable timestamps with random bits, which improves index locality compared with purely random UUIDs.
Why Use UUID v7?
- Better database index behavior in append-heavy workloads
- Maintains uniqueness guarantees with strong random entropy
- Standardized format with interoperable tooling
Frequently Asked Questions
Is UUID v7 better than v4?
For ordered inserts and timeline-oriented records, v7 is typically better due to temporal ordering.
Need a random-only UUID?
Use UUID v4 Generator for random-only identifiers.
