public enum CircuitState extends Enum<CircuitState>
Defines the states of circuit breaker.
  • Enum Constant Details

    • CLOSED

      public static final CircuitState CLOSED
      Initial state. All requests are sent to the remote service.
    • OPEN

      public static final CircuitState OPEN
      The circuit is tripped. All requests fail immediately without calling the remote service.
    • HALF_OPEN

      public static final CircuitState HALF_OPEN
      Only one trial request is sent at a time until at least one request succeeds or fails. If it doesn't complete within a certain time, another trial request will be sent again. All other requests fails immediately same as OPEN.
