Subject [jira] [Commented] (HBASE-11572) Add support for doing get/scans against a particular replica_id
Date Wed, 23 Jul 2014 00:40:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14071193#comment-14071193

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.
