我遇到了来自 Spring Boot 应用程序与 D1 Google CloudSQL Server 通信的间歇性连接错误,这里描述的配置设置为HikariCP MySQL 设置
我想知道是否有人以前遇到过这种情况。
我已阅读此处发布的常见问题解答Hikari 常见问题解答,我想知道我的默认 idleTimeout 和 maxLifeTime(30 分钟)设置是否有问题;服务器上的 wait_timeout 和 interactive_timeout 都设置为默认 28800 秒(8 小时)。
常见问题解答说这两个设置应该比服务器设置少大约一分钟,但是如果我在 30 分钟后失去连接,我不太明白将 maxLifeTime 提高到 7hrs 59mins 会如何改善这种情况。
有人有什么建议吗?

我认为目前索引并不是特别快,因为我没有使用预测。该过程大约需要 30 分钟才能执行。
谢谢
