mysql-async允许开发者根据自身业务需求灵活配置连接池的大小,比如,在一台配置为16GB内存的服务器上,若预估每秒钟需要处理数百个并发请求,则建议将连接池大小设置为50或更高,以此来保证系统在面对高流量冲击时仍能保持良好的性能表现。 此外,mysql-async还提供了自动健康检查功能,能够定期检测池内连接的状态,及时剔除...
MySQL Sync 和 Async 概念 MySQL中的sync和async主要指的是数据同步和异步的概念,它们在数据库操作中扮演着重要的角色。 Sync(同步) 概念: 同步是指在执行数据库操作时,程序必须等待操作完成后才能继续执行后续的操作。这意味着如果一个操作需要花费较长时间,那么整个程序的执行会被阻塞。
