Concept about rate limiter constructed by redis cluster

I Have a concept problem about rate limiter constructed by redis/cluster mode. My problem is if I choose token bucket algorithm for rate limiter and use just one redis server, it works well. However if the traffic of redis is too much now, I would like to use redis/cluster mode for horizontal-scaling, but as I know, the redis/cluster mode is eventually consistent, so I think the value of each redis node will not be strongly consistent at the same time, the rate limiter will sometimes have some wrong calculation right? If so, how do I fix the issue, thank you very much.
