    Configures the Tunable request timeout of this server or client (if applying the Tunable produces a value of None, an unbounded timeout is used for the request).

    If the request has not completed within the Duration resulting from timeout.apply(), the pending work will be interrupted via com.twitter.util.Future.raise.

    Client's Request Timeout

    The client request timeout is the maximum amount of time given to a single request (if there are retries, they each get a fresh request timeout). The timeout is applied only after a connection has been acquired. That is: it is applied to the interval between the dispatch of the request and the receipt of the response.

    Server's Request Timeout

    The server request timeout is the maximum amount of time, a server is allowed to spend handling the incoming request. Using the Finagle terminology, this is an amount of time after which a non-satisfied future returned from the user-defined service times out.

    Configure a com.twitter.finagle.service.ResponseClassifier which is used to determine the result of a request/response.

    This allows developers to give Finagle the additional application-specific knowledge necessary in order to properly classify responses. Without this, Finagle cannot make judgements about application-level failures as it only has a narrow understanding of failures (for example: transport level, timeouts, and nacks).

    As an example take an HTTP server that returns a response with a 500 status code. To Finagle this is a successful request/response. However, the application developer may want to treat all 500 status codes as failures and can do so via setting a com.twitter.finagle.service.ResponseClassifier.

    ResponseClassifier is a PartialFunction and as such multiple classifiers can be composed together via PartialFunction.orElse.

    Response classification is independently configured on the client and server. For client-side response classification using com.twitter.finagle.builder.ClientBuilder, see com.twitter.finagle.builder.ClientBuilder.responseClassifier

    An entry point for configuring the client's sessions.

    Session might be viewed as logical connection that wraps a physical connection (i.e., transport) and controls its lifecycle. Sessions are used in Finagle to maintain liveness, requests cancellation, draining, and many more.

    The default setup for a Finagle client's sessions is to not put any timeouts on it.
