> Refactoring ReplicationSink to make it more responsive of cluster health

> Key: HBASE-6545
> URL: https://issues.apache.org/jira/browse/HBASE-6545
> Project: HBase
> Issue Type: New Feature
> Components: Replication
> Reporter: Himanshu Vashishtha
> Priority: Major
>
> ReplicationSink replicates the WALEdits in the local cluster. It uses native
> HBase client to insert the mutations. Sometime, it takes a while to process
> it (region splitting, gc pause, etc) and it undergoes the retrial phase. It
> has two repercussions:
> a) The regionserver handler which is serving the request is blocked for this
> period.
> b) The caller may get timed out and it will retry it anyway, but the handler
> serving the ReplicationSink requests is still working.
