Why Your Database Performance Crashes with UUID v4—and How UUID v7 Fixes It
UUID v4가 부른 데이터베이스 성능 저하, UUID v7로 해결하다
Why it matters
The shift from UUID v4 to UUID v7 represents a critical database optimization strategy. UUID v4's random nature causes severe index fragmentation and expensive B-tree rebalancing with every insert, while UUID v7's timestamp-based ordering maintains sequential patterns that keep indexes efficient and write performance high. With widespread language support and drop-in compatibility, UUID v7 enables developers to adopt distributed identifiers without sacrificing database scalability.
