[jira] [Commented] (HBASE-2196) Support more than one slave cluster

    [ https://issues.apache.org/jira/browse/HBASE-2196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13102159#comment-13102159 ] 

Lars Hofhansl commented on HBASE-2196:
--------------------------------------

It seems the naive way would just to create multiple ReplicationSources.
Each peer cluster would need to be handled in its own thread anyway (so that one slow peer does not slow all replication).

>From a quick pass over the code I see no reason why that would not just work.

There would be some overhead of course that could be avoided, such as each ReplicationSource reading the same log files; these files are cached after the first read, though. As well as multiple local ZooKeeper connections, where in theory one would suffice.

I am also probably missing something. :)
