Github user aberghage commented on the issue: https://github.com/apache/zookeeper/pull/440 I apologize for the somewhat substance-light addition to the conversation, but having grafted some super crude histogram upgrades on counters in our patchset I'd be very much in favor of pulling in a library that does it right, which this seems to do. That said, splitting concerns between the new dependency and new metric also sounds correct to me.
