---------------------------------------
Summary: Report percentFilesLocalPrimaryRegions metric
Key: HBASE-29068
URL: https://issues.apache.org/jira/browse/HBASE-29068
Project: HBase
Issue Type: Improvement
Components: metrics, read replicas
Reporter: Charles Connell
Assignee: Charles Connell
If you are running a table with region replicas, the secondary replicas usually
cannot achieve 100% locality. Currently a RegionServer reports two locality
metrics:
* percentFilesLocal
* percentFilesLocalSecondaryRegions
Both of these will be less than 100% if region replicas are enabled. The best
we can do is get 100% locality for the primary replicas, but there is currently
no way to see if we've achieved it.
I propose introducing the new metric {{percentFilesLocalPrimaryRegions}}
