存储数据时偶尔出现ReadTimeout问题

当更新存储某数据时偶尔会出现ReadTimeout问题，导致没有存成功，但代码中会先后存储A、B两条数据，如果A成功了B没成功，会导致很严重的数据不同步问题。请问这个情况该如何避免？谢谢！
问题报错如下：

谢谢。。。那么。。。好像就非常麻烦了，上万行的服务器端代码，几十上百个云函数，大多都有多处不同时的save/update操作，如果每个地方都需要做异常判断，真是...复杂的很了...

请问有没有包装好的(或者该如何包装)判断一个save/update是否异常，如果异常则重试呢？

谢谢回复，请问MySQL为什么就可以规避这样的问题了？

原来如此，谢谢！
