Create delaying rate settingsSource:
rate_delay(pause = 1, max_times = Inf) rate_backoff( pause_base = 1, pause_cap = 60, pause_min = 1, max_times = 3, jitter = TRUE ) is_rate(x)
Delay between attempts in seconds.
Maximum number of requests to attempt.
- pause_base, pause_cap
rate_backoff()uses an exponential back-off so that each request waits
pause_base * 2^iseconds, up to a maximum of
Minimum time to wait in the backoff; generally only necessary if you need pauses less than one second (which may not be kind to the server, use with caution!).
Whether to introduce a random jitter in the waiting time.
An object to test.
# A delay rate waits the same amount of time: rate <- rate_delay(0.02) for (i in 1:3) rate_sleep(rate, quiet = FALSE) #> Retrying in 0.02 seconds. #> Retrying in 0.02 seconds. # A backoff rate waits exponentially longer each time, with random # jitter by default: rate <- rate_backoff(pause_base = 0.2, pause_min = 0.005) for (i in 1:3) rate_sleep(rate, quiet = FALSE) #> Retrying in 0.047 seconds. #> Retrying in 0.29 seconds.
