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.

    Apply f on created services, returning the resulting Future in their stead.

    Apply f on created services, returning the resulting Future in their stead. This is useful for implementing common factory wrappers that only need to modify or operate on the underlying service.
