It is adjusted to open state, forbids all destination request invocation target services, in such manner, it is possible to avoid more destination request tune
With failure.In addition, fail counter triggers timer while adjusting circuit-breaker status restarts timing, the of timing
After one time-count cycle, circuit-breaker status is adjusted to semi-open state, a certain proportion of destination request is allowed to call mesh
Mark service.For in each time-count cycle later, if fail counter is judged currently to count in current time-count cycle
The quantity of the destination request of malloc failure malloc is greater than preset threshold in one number time, then, fail counter can trigger timer again
Start timing, and the timing since first time-count cycle, is lost if fail counter is judged to call in the current count period
The quantity of the destination request lost is not more than preset threshold, then, timer can adjust target proportion, then proceed by next
Time-count cycle allows the quantity of the destination request of invocation target service that can also change, works as mesh with the adjustment of target proportion
When mark ratio reaches 100%, it is equivalent to, circuit-breaker status is the state closed, then, directly circuit-breaker status is adjusted to close
The state closed, and target proportion is reverted into initial proportion, restart timing convenient for subsequent fail counter triggering timer
Afterwards, target proportion is adjusted.
