1. class FailureAccrualFactory[Req, Rep] extends ServiceFactory[Req, Rep]

   

   A com.twitter.finagle.ServiceFactory that accrues failures, marking itself unavailable when deemed unhealthy according to the configured policy.

   A com.twitter.finagle.ServiceFactory that accrues failures, marking itself unavailable when deemed unhealthy according to the configured policy.

   This acts as a request driven circuit breaker.

   Note this module fails open – that is, even if it transitions into a closed state, requests will still be allowed to flow through it. Although, when used in a typical Finagle client, there is one instance of this module per node and as such, the load balancer will avoid nodes where the status is not open.

2. abstract class FailureAccrualPolicy extends AnyRef

   

   A FailureAccrualPolicy is used by FailureAccrualFactory to determine whether to mark an endpoint dead upon a request failure.

   A FailureAccrualPolicy is used by FailureAccrualFactory to determine whether to mark an endpoint dead upon a request failure. On each successful response, FailureAccrualFactory calls recordSuccess(). On each failure, FailureAccrualFactory calls markDeadOnFailure() to obtain the duration to mark the endpoint dead for; (Some(Duration)), or None.
