class AkkaCircuitBreaker extends CircuitBreaker
trait CircuitBreaker extends AnyRef
class CircuitBreaking extends SimpleFilter[Request, Response]

An HTTP filter which adds circuit breaking to any service.
An HTTP filter which adds circuit breaking to any service. CAn be used on service or client side. Converts unexpected exceptions and broken circuit problems into 503 errors to the upstream client.
case class CircuitBroken(circuitName: CircuitName, reason: String) extends Exception with Product with Serializable

The exception thrown from the circuit breaker when the circuit is open.
The exception thrown from the circuit breaker when the circuit is open.
circuitName
the name
reason
detail about why this exception was raised
case class CircuitConfig(circuitName: CircuitName, timeout: Duration, downTime: Duration, failLimit: Int) extends Product with Serializable

Configuration of a circuit.
Configuration of a circuit.
circuitName
the name of the circuit (or downstream system) to use.
timeout
the duration after which a call will be counted as a failure.
downTime
when the circuit is broken, it will not attempt to pass through any traffic for at least this amount of time.
failLimit
the number of consecutive failures before tripping the circuit.
final case class CircuitName(value: String) extends AnyVal with Product with Serializable
case class CircuitStateChange(circuitName: CircuitName, state: CircuitStatus) extends Product with Serializable

object CircuitConfig extends Serializable
object CircuitStatus extends Enumeration

Circuit states.
Circuit states. Of note is HalfOpen: - The first call attempted is allowed through without failing fast - All other calls fail-fast with an exception just as in Open state - If the first call succeeds, the breaker is reset back to Closed state - If the first call fails, the breaker is tripped again into the Open state for another full resetTimeout
