Subject [jira] [Commented] (HBASE-11367) Pluggable replication endpoint
Date Tue, 09 Sep 2014 20:32:28 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14127501#comment-14127501

Enis Soztutar commented on HBASE-11367:

bq. Maybe it could be possible to introduce a pluggable replication API to 0.98 that looks
really similar to the branch-1/master API without significant code change to replication internals
in 0.98
Code-wise, there was some refactoring done for the replication internals, but there should
not be any behavioral / semantic changes in this patch. But, agreed that this is better discussed
specifically for 0.98 in a separate jira. 
bq. I suggest opening a backport JIRA because making a pluggable replication endpoint in 0.98
seems a separate subject now.

> We need a pluggable endpoint for replication for more flexibility. See parent jira for
more context. 
> ReplicationSource tails the logs for each peer. This jira introduces ReplicationEndpoint
which is customizable per peer. ReplicationEndpoint is run in the same RS process and instantiated
per replication peer per region server. Implementations of this interface handle the actual
shipping of WAL edits to the remote cluster.
