MySQL Scalability & Sharding: Vitess vs TiDB (10k+ TPS)
MySQL Scalability & Sharding: Vitess vs TiDB (10k+ TPS) Answer-first: Scaling MySQL requires a phased architectural progression: optimizing InnoDB buffer pools (100–500 TPS), implementing ProxySQL read/write splitting (500–3,000 TPS), and migrating to horizontal sharding or TiDB Distributed SQL (3,000–10,000+ TPS). TiDB serves as the premier MySQL sharding alternative, eliminating manual application-level partitioning through stateless SQL compute nodes and Raft-replicated distributed TiKV storage. MySQL scalability is the ability to increase database throughput — reads per second, writes per second, or data volume — without rewriting your application. The critical distinction: read scaling (adding replicas) and write scaling (sharding or distributed SQL) require completely different architectural approaches. Choosing the wrong path creates technical debt that takes months to unwind. ...
