Description

Issue Description

Type: feature request

Describe what happened (or what feature you want)

       ClusterNode clusterNode = ClusterBuilderSlot.getClusterNode(this.getResource());
        if (clusterNode == null) {
            return true;
        }

这里熔断降级是根据当前的资源进行降级的，期望能否把第三方的一组接口当成一个资源，如果一个接口出现异常或者时延较高，则对当前组的接口进行熔断降级。

Describe what you expected to happen

        Node selectedNode = selectNodeByRequesterAndStrategy(rule, context, node);
        if (selectedNode == null) {
            return true;
        }

期望也跟流控一样可以根据同一个origin进行熔断降级

Research direction
Investigate the existing circuit breaker logic in Sentinel, particularly the ClusterNode and DegradeSlot. Review the comments on issue #605 for proposed solutions. Look at how flow control uses selectNodeByRequesterAndStrategy to potentially reuse similar patterns for circuit breaking based on other resource statistics.
