LRU is not good for Bayesian statistics as it leaves a lot of meaningless tokens. "used" != "useful".
And it can be harmful for other data if you store everything in the same Redis instance.
I would suggest to use smarter Bayes expiry module instead of LRU policy. Or, better yet, expiry module in conjunction with a separate Redis instance and volatile-ttl policy for statistics.
