Why Your Database Primary Key Should Be a UUIDv7
from Database Tech with Fexingo: SQL, NoSQL, and Data Storage Conversations Hosted by Fexingo
Database primary keys seem simple—until they bite you. Most developers default to auto-increment integers or standard UUIDs without thinking about the implications. In this episode, Lucas and Luna break down exactly why UUIDv7 is becoming the go-to choice for modern applications. They explain how auto-increment keys create write hotspots in distributed systems, why UUIDv4 wrecks B-tree index performance, and how UUIDv7's time-ordered design keeps indexes lean while staying globally unique. Real benchmarks from a ride-hailing platform show a 40% reduction in index page splits after migrating from UUIDv4 to UUIDv7. If you design database schemas or care about write throughput, this episode gives you a concrete decision framework. #UUIDv7 #PrimaryKey #DatabaseDesign #PostgreSQL #MySQL #DistributedSystems #IndexPerformance #BTree #WriteThroughput #AutoIncrement #UUIDv4 #DatabaseSchema #DatabaseTechWithFexingo #Technology #FexingoBusiness #BusinessPodcast #DataEngineering #BackendEngineering Keep every episode free: buymeacoffee.com/fexingo
