  • :exceptions_to_allow (Integer) —

    The number of exceptions to allow.

  • :maximum_attempts (Integer) —

    The maximum number of attempts to make before the task is marked as failed.

  • :maximum_retry_interval_seconds (Integer) —

    The maximum retry interval, in seconds.

  • :exceptions_to_retry (Array) —

    The list of exceptions that will cause a retry attempt.

  • :exceptions_to_exclude (Array) —

    The list of exceptions to exclude from retry.

  • :jitter_function (Object) —

    The jitter function used to modify the actual retry time.

  • :retries_per_exception (Integer) —
