Description

feature: 配置集群限流时候,建议有个单机的阈值兜底. 目前的如果选择集群限流后, count是集群限流的阈值, 如果出现降级, 使用的是集群限流的阈值, 建议加一个单机阈值, 降级时候使用单机阈值,而不是集群阈值

Contributor guide

Research direction
Look into the cluster flow control implementation in Sentinel. Identify where the cluster threshold is applied and where a fallback to a single machine threshold could be added. Modify the configuration to support both cluster and single machine thresholds, and ensure that during degradation, the single machine threshold is used instead of the cluster threshold. Write tests for the new behavior.
