class FailureAccrualFactory[Req, Rep] extends ServiceFactory[Req, Rep]
A com.twitter.finagle.ServiceFactory that accrues failures, marking itself unavailable when deemed unhealthy according to its configuration.
This acts as a request driven circuit breaker.
When used in a typical Finagle client, there is one instance per node and as such, the load balancer will avoid nodes that are marked down via failure accrual.
