jeffkbkim opened a new pull request, #16949: URL: https://github.com/apache/kafka/pull/16949
This patch introduces a wrapper around [HdrHistogram](https://github.com/HdrHistogram/HdrHistogram) to use for group coordinator histograms, event queue time, event processing time, flush time, and purgatory time. Note that the wrapper refreshes histogram snapshots on a query/read basis - it does not refresh the snapshot if metrics(max, p99, etc) are never queried. The implication is that if we collect metrics at, say every 60s, then the first query will contain 60s worth of data whereas the subsequent queries will generate a new snapshot ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
