Performance Comparison of UUID, Auto‑Increment, and Random Keys in MySQL

This article investigates MySQL's recommendation against using UUID or random Snowflake IDs as primary keys by creating three tables with different key strategies, running Spring Boot/JDBC performance tests, analyzing index structures, and concluding that auto‑increment keys offer superior insertion efficiency and fewer drawbacks.

Performance Comparison of UUID vs Auto-Increment IDs in MySQL

Benchmarking three MySQL tables—auto_increment, UUID, and random long keys—shows that sequential auto_increment inserts are fastest, random keys are slower, and UUIDs dramatically lag due to random I/O and fragmentation, so use auto_increment for most workloads and reserve UUIDs only for required global uniqueness.
