final class HalfOpen extends State

State of the CircuitBreaker in which the circuit breaker has already allowed a task to go through, as a reset attempt, in order to test the connection.

Contract:

  • The first task when Open has expired is allowed through without failing fast, just before the circuit breaker is evolved into the HalfOpen state
  • All tasks attempted in HalfOpen fail-fast with an exception just as in Open state
  • If that task attempt succeeds, the breaker is reset back to the Closed state, with the resetTimeout and the failures count also reset to initial values
  • If the first call fails, the breaker is tripped again into the Open state (the resetTimeout is multiplied by the exponential backoff factor)
