> 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.
