Examples of com.netflix.hystrix.HystrixCommandKey

com.netflix.hystrix.HystrixCommandKey
A key to represent a {@link HystrixCommand} for monitoring, circuit-breakers, metrics publishing, caching and other such uses.
This interface is intended to work natively with Enums so that implementing code can be an enum that implements this interface.
