Description

Saying short-circuit, I means a fault tolerant concept in Hystrix.

I think we should support this feature internally in Dubbo. Cluster is a good Extension point to do this.

Contributor guide

Research direction
Explore Dubbo's Cluster extension mechanism and implement a circuit breaker pattern (similar to Hystrix) by wrapping the existing Cluster invoker to track failures and open the circuit.
