> And I think a more straightforward way to do this probably would be to log slow fetches which are slower than most fetches. For example, we could log the 5%th percentile slow fetches among all fetches. The downside is that we have to store more intermediate states. This is a great idea actually. We can use [Dropwizard's Histogram with a uniform reservoir](https://metrics.dropwizard.io/4.1.2/manual/core.html#histograms) to keep histogram information with constant storage space. -- This is an automated message from the Apache Git Service.
