> > I think that it is needed to speed up caculating, but in most case, we need to know the real time cluster replica statistic, cache may be confused when we need to track some cluster problems > > The cache is configurable, maybe set cache timeout 0 to disable. The cache is mostly to prevent high frequency query in a short time that may cause high calculation cost and heavy lock competitions, maybe 1s is close enough from real-time refreshing. > > The cache is easy to implement, the state is restored in the previous version and may cause concurrent issue, so the cache is kind of fixing a concurrent bug rather than a new feature. may we can provide two choice, sync or async, so that for high frequency query we can use async model, for other normal user, just speed up caculating and use sync model, what do you think about it? -- This is an automated message from the Apache Git Service.
