High-Performance C++ Optimization: From Theory to Practice — The Road to PolarDB TPC-C Performance Leadership
PolarDB-MySQL became the TPC-C performance leader in January 2025, achieving a total throughput of 2.05 billion TpmC and 878,000 TpmC per single node. I led the performance optimization work on the database nodes. This talk introduces the optimization strategies implemented for PolarDB under the TPC-C scenario and how we incrementally improved performance to reach the current level. **Outline:** 1. Introduction to the TPC-C Scenario 2. Our Optimization Work 2.1 Performance Improvements on Database Nodes 2.2 Improved Replication Speed Between Database Nodes 2.3 Stability of Database Node Performance 3. Summary
