-------------------------------------
Summary: 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

Benefit:
# Table Latency Metrics could removed after table has been moved away. Fix
[HBASE-27617|https://issues.apache.org/jira/browse/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 hadoop-metrics2 with
hbase-metrics.
Influence:
# The metrics structure in jmx will change.
