-------------------------------------------
> Sorry I'm not sure how should I do, would you please give me some infos or an
> example? Thank you.
When we go to resolve this jira, the popup window will have a text box for
"Release notes". We just need to describe the change there so that people who
upgrade to 2.6.0 when it is released know that they might need to update their
metric collection.
> Refactor Table Latency Metrics

> Benefit:
> # Table Latency Metrics could removed after table has been moved away. Fix
> HBASE-27617
> # Could remove the hash lookup caused by metrics map from the hot request
> path.
> # Reduce the output in jmx. As if we use jmx_exporter to collect metrics to
> Prometheus, the operation overhead of performing regular matching in metric
> is relatively high(especially region metrics, which might be next step).
> # I think that could be the first step after hbase-metrics released. It
> seems that the roadmap indicates that we should replace directly use
> hadoop-metrics2 with hbase-metrics.
> Influence:
> # The metrics structure in jmx will change.
