Spring-Redis-Cache：如果我们在天蓝色的情况下重新启动redis，需要花费一些时间重新连接

问题描述

我们正在使用带有2.3.1-Spring发行版的Spring Boot的Lettuce静态Redis。当我们在Azure上部署应用程序并连接到Azure上的Redis缓存时，我们看到一个奇怪的问题。如果我们重新连接需要15分钟以上重新启动我们的redis应用程序。但是，当我们在本地运行同一应用程序时，从本地连接到azure redis实例时，重新启动时只需不到5分钟即可重新连接。

我们是否需要更改azure或springboot应用程序上的任何配置以在连接可用后立即强制重新连接。以下是我们的日志。
