> 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}},
> which will close this gap.
