        limit is hit. "wait" mode will, once the limit is hit, wait and retry the request as soon
        as the rate limit resets, until it succeeds. "pace" works like throw, but tries to wait in
        between calls so that the limit is generally not hit (How hard it tries to not hit the rate
        limit can be controlled by ratelimit_pacefactor). The default setting is "wait". Note that
