Type declaration

  • initialWaitMs: number

    The initial delay, which will be doubled on every subsequent retry

  • maxRetryMs: number

    The max number of ms to retry before giving up and throwing a RetryTimeoutError. Note that this is an absolute value which includes time spent actually running the job. For example, if you set this to 1 hour and your job takes 30 minutes to run, you will only get 2 retries.
