public class DegradeRule extends AbstractRule

Degrade is used when the resources are in an unstable state, these resources will be degraded within the next defined time window. There are two ways to measure whether a resource is stable or not:

  • Average response time (DEGRADE_GRADE_RT): When the average RT exceeds the threshold ('count' in 'DegradeRule', in milliseconds), the resource enters a quasi-degraded state. If the RT of next coming 5 requests still exceed this threshold, this resource will be downgraded, which means that in the next time window (defined in 'timeWindow', in seconds) all the access to this resource will be blocked.
  • Exception ratio: When the ratio of exception count per second and the success qps exceeds the threshold, access to the resource will be blocked in the coming window.
