[jira] [Commented] (HBASE-11572) Add support for doing get/scans against a particular replica_id

["Nick Dimiduk (JIRA)" <ji...@apache.org>]

Nick Dimiduk commented on HBASE-11572:
--------------------------------------

Isn't it better to leave the client ignorant of specific replicas? It makes sense for tests, but how is it helpful for prod usecases? Maybe you have an example?

> We have support for doing an rpc against the primary region in get/scans and also new functionality for doing failover get/scan RPCs trying primary first then doing backup rpcs to secondaries when the first one times out. 
> We can add functionality for doing get/scan against a particular replica_id so that we can use it in tests, or by clients in some specific situations. 
> We can think about adding support for querying the replica_id from get/scan responses coming from failover rpcs so that the client can then issue a follow up request against that particular replica_id.
