backoff-time clj

(backoff-time slot-time-ms attempt)

config->runner clj

(config->runner {:keys [max-attempts strategy-parameters catch? failed?]
                 :or {catch? (constantly false) failed? (constantly false)}
                 :as retry-config})

exponential-backoff-config clj

(exponential-backoff-config max-attempts
                            slot-time-ms
                            &
                            {:keys [catch? failed?] :as control-fns})

Uses an exponential backoff algorithm, meaning that, for every attempt, it will wait K * slot-time-ms, where K is a random number between 0 and 2^c - 1, c being the attempt index.

simple-sleep-config clj

(simple-sleep-config max-attempts
                     sleep-ms
                     &
                     {:keys [catch? failed?] :as control-fns})

Between each attempt sleep for sleep-ms seconds.

sleep-fn clj

(sleep-fn {:keys [strategy] :as sleep-args})

with clj macro

(with runner-config & body)

Tries to run body using the provided configuration.
