/*+[auto_commit]*/ ,需要修改Mysql源码，成本很高，一般公司没有技术能力、 42 | 2，使用存储过程，整个事务放在MySQL完成（银行经常使用） 43 | 44 | 45 | 46 | 47 | 优化总结： 48 | 前端控制：暴露接口，按钮防止重复点击 49 | 动态数据分离:CDN缓存，后端缓存(memcached,redis) 50 | 事务竞争优化：减少事务锁时间 51 | 事务的优化： 52 | 存储过程 53 | 1，存储过程优化，优化事务行级锁持有时间 54 | 2，不要过度依赖存储过程 55 | 3，简单逻辑，可以应用存储过程 56 | 4, qps 一个秒杀6000/qps 57 | 58 | 59 | 60 | 61 | 智能DNS解析<-----------流量 62 | | | 63 | Nginx | Nginx | 64 | | CDN
