> Refactor Table Latency Metrics
> ------------------------------
>
> Key: HBASE-27681
> URL: https://issues.apache.org/jira/browse/HBASE-27681
> Project: HBase
> Issue Type: Improvement
> Reporter: tianhang tang
> Assignee: tianhang tang
> Priority: Major
> Attachments: image-2023-03-01-23-55-14-095.png,

>
> 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.
