Subject [jira] [Updated] (HBASE-10504) Define Replication Interface
Date Thu, 12 Jun 2014 01:32:03 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10504?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Enis Soztutar updated HBASE-10504:
----------------------------------

    Attachment: hbase-10504_v1.patch

Attaching the first version patch as an inclusion candidate. Would be good to have this in
1.0. 

Patch adds a new plugin point ReplicationEndpoint. ReplicationSource tails the log, ReplicationEndpoint
implementations are responsible for actually shipping the edits to the other (hbase or non-hbase)
cluster. 

ReplicationEndpoint can be defined per peer. Default inter-cluster replication works without
any changes (lily etc should still work).

> 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.
