  5. def apply(backoff: (Int) ⇒ Option[FiniteDuration], retriable: (Request, Either[Throwable, Response]) ⇒ Boolean = defaultRetriable): RetryPolicy

    Decomposes a retry policy into components that are typically configured individually.

    Decomposes a retry policy into components that are typically configured individually.

    backoff

    a function of attempts to an optional FiniteDuration. Return None to stop retrying, or some duration after which the request will be retried. See exponentialBackoff for a useful implementation.

    retriable

    determines whether the request is retriable from the request and either the throwable or response that was returned. Defaults to defaultRetriable.

  8. def defaultRetriable(req: Request, result: Either[Throwable, Response]): Boolean

    Default logic for whether a request is retriable.

    Default logic for whether a request is retriable. Returns true if the request method does not permit a body and the result is either a throwable or has one of the RetriableStatuses.

    Caution: more restrictive than 0.16. That would inspect the body for effects, and resumbmit only if the body was pure (i.e., only emits and halts). The fs2 algebra does not let us inspect the stream for effects, so we can't safely resubmit. For the old behavior, use unsafeRetriable. To ignore the response codes, see recklesslyRetriable.

    Like unsafeRetriable, but returns true even if the request method is not idempotent.

    Like unsafeRetriable, but returns true even if the request method is not idempotent. This is useful if failed requests are assumed to have not reached their destination, which is a dangerous assumption. Use at your own risk.

    Caution: if the request body is effectful, the effects will be run twice. The most common symptom of this will be resubmitting an empty request body.
