This article provides details and benchmark test results for Mysql queries per second, explaining my earlier conversations on Mysql Connect. Review the improvement history of MySQL/InnoDB. You can easily find out. MySQL 5.6 has never been faster

Optimization of queries with any combination of multiple fields with high concurrency and low base. Optimization of highly concurrent and low-base multi-field queries with any combination 1. the problem first explains what the low-base multi-field

The test process is as follows: MySQL is tested from 10, 20, 50, and 100 threads in four application scenarios. The test results show that: for scenario 1) general concurrent access can meet the requirements; for scenario 2) and 3) response time in
