HalfOpen

class HalfOpen : CircuitBreaker.State(source)

The CircuitBreaker is in HalfOpen state while it's allowing a test request to go through.

All other requests made while the test request is still running will short-circuit/fail-fast.
If the test request succeeds, then the CircuitBreaker is tripped back into Closed, with the reset timeout, and the failures count also reset to their initial values.
If the test request fails, then the CircuitBreaker is tripped back into Open, the resetTimeout is multiplied by the exponentialBackoffFactor, up to the configured maxResetTimeout.

Parameters

resetTimeout

is the current reset timeout that the CircuitBreaker has to stay in Open state. When the reset timeout lapsed, than the CircuitBreaker will allow a test request to go through in HalfOpen. If the test request failed, the CircuitBreaker will go back into Open and it'll multiply the resetTimeout with the exponential backoff factor.
