Lars Hofhansl commented on HBASE-12988:
---------------------------------------
[~busbey], this the replication issue we had discussed on Wednesday. Very
simple, avoid huge refactoring by breaking a batch already assembled into
pieces before sending to the slave(s). Ideally we'd interleave everything
(reading the logs, shipping data across the wire, and applying the edits), this
does only the latter two (but avoids a major refactoring).
