当 master 节点发布重启的时候,client 节点会因为找不到 master 降级为单机限流,但是我们发现线上在这个瞬间部分请求就会出现超时的现象,这个有什么方法可以避免,所以我们现在的操作都是在发布之前先主动将集群限流切换至单机限流,再发布完后切回集群限流,但是这样就比较麻烦,有什么好的思路解决这个问题呢?

## Issue Description 在限流规则上,目前有令牌桶,漏斗,滑动窗口,固定窗口等规则,为什么 sentinel 选择了滑动窗口作为集群限流的规则那,是否考虑支持业务自己配置限流规则,在集群限流的场景下。期待您的解答~ ### Describe what feature you want ### Describe your initial design (if present) ### Additional context Add any other context or screenshots about the...

### What changes were made? - 新增 Nacos 持久化规则配置支持 ### Why are these changes needed? - 当前 Sentinel Dashboard 无法保存用户配置的规则,重启sentinel之后又得重新配置,于是想到了关于用nacos持久化的问题, ### How to verify these changes? 1. 先在nacos中创建一个命名空间 sentinel-namespace 2....

你好,我目前想在多个实例上使用sentinel,通过定期检查下游资源的负载情况,动态调整当前周期的限流上限。 而且因为这多个实例启动的时间不一致,因此会存在这种情况:实例A正在以最大限流运行,此时实例B启动,实例A需要降低限流上限,而实例B需要从最小的限流值开始,逐步增加到实例A与实例B都能平稳运行的限流值(期望能尽可能平均,或者可以参考拥塞控制算法,实例A限流上限先减半,实例B可以分到一些资源)。 从目前Sentinel文档看的话,似乎暂时不支持这种情况。想咨询一下,这种需要动态调整限流的case,可以使用Sentinel实现吗?或者可以支持吗?
