Michael Stack commented on HBASE-24459:
---------------------------------------

Duo has talked of keeping the ConnectionRegistry Interface read-only and simple 
so Implemention could go against an existing caching tier.

Could also keep the cache tier in-cluster with Master farming out location 
updates on (rare) change via remote procedure infrastructure so any 
RegionServer can participate?

For implementation later.

> Now the related code is only in AsyncMetaRegionTableLocator, we could make
