Lars Hofhansl commented on HBASE-12988:
---------------------------------------
That'd save CPU on the replication source. I have the feeling that would not do
much to speed things up. What's slow (and I say this without having verified in
detail) is the sequential reading of the WAL and non-streaming writes to the
replication sink with absolutely no parallelism.
Maybe I'll put instrumentation in to measure exactly where it's slow, but I am
fairly certain it is shipping the edit to the sink and applying them there.
