### About Addresses the race described [here](https://github.com/apache/kafka/pull/16949#discussion_r1750273695) and adds a JMH benchmark comparing `HdrHistogram` with Yammer's histogram. - A sample result from a local run on my development machine: ``` Benchmark Mode Cnt Score Error Units HistogramBenchmark.runner avgt 5 410.811 ± 95.204 ns/op HistogramBenchmark.runner:read_HdrHistogram avgt 5 50.839 ± 11.850 ns/op HistogramBenchmark.runner:read_YammerHistogram avgt 5 51.206 ± 11.789 ns/op HistogramBenchmark.runner:write_HdrHistogram avgt 5 314.767 ± 93.978 ns/op HistogramBenchmark.runner:write_YammerHistogram avgt 5 986.574 ± 214.357 ns/op ``` ### Testing I haven't included a test reproducing the race, because on my development machine I wasn't able to see consistent reproducibility without more sophisticated testing tools like jcstress or Byteman/BMUnit. The race is easily reproducible manually while debugging the test. ### 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.
