Subject [jira] [Commented] (HBASE-10504) Define Replication Interface
Date Mon, 16 Jun 2014 23:57:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14033203#comment-14033203
] 

Enis Soztutar commented on HBASE-10504:
---------------------------------------

bq. As long as the RE daemons are disjoint from the region servers that would work, since
you need to be able to have as many/few of them as you want, plus to be able to have them
on different machines.
bq. I could even see this as being useful for certain use cases that want inter-HBase replication
to be done through specific gateways.
Sounds good to me. I think it is ok to maintain such a gateway inside hbase proper. 

[~jdcryans] mind giving the patch a review? Do you want to do this in a subtask?

> HBase has replication.  Fellas have been hijacking the replication apis to do all kinds
of perverse stuff like indexing hbase content (hbase-indexer https://github.com/NGDATA/hbase-indexer)
and our [~toffer] just showed up w/ overrides that replicate via an alternate channel (over
a secure thrift channel between dcs over on HBASE-9360).  This issue is about surfacing these
APIs as public with guarantees to downstreamers similar to those we have on our public client-facing
APIs (and so we don't break them for downstreamers).
> Any input [~phunt] or [~gabriel.reid] or [~toffer]?
> Thanks.
