Sean Busbey commented on HBASE-15995:
-------------------------------------

Are we trying to go further down the "no guarantee of order" path? I was hoping we'd go more
towards fixing that.

> Currently ReplicationSource reads edits from the WAL and ships them in the same thread.
> By breaking out the reading from the shipping, we can introduce greater parallelism and
lay the foundation for further refactoring to a pipelined, streaming model.
