Date Sat, 04 Feb 2017 12:23:51 GMT

Ted Yu commented on HBASE-15995:
--------------------------------

[~vincentpoon]:
Can you generate patch for master branch one last time (there is conflict in ReplicationSource.java)
?

I can resolve the conflict locally but the patch should bear your identity.

Thanks

> 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.
