Jesse Yates commented on HBASE-8737:
------------------------------------
I'm a little slow today... any chance we can figure out likely data sizes based
on whether or not we are getting a SizedCellScanner? So, if its sized, then we
should use that (agreeing with you above), but when do we not get that and can
we make any assumptions about the size of the data?
A 2x improvement is a pretty big jump... it might be worth doing (1) about
instrumenting this a little bit so people can see if they should switch to
using the counting and then (2) making the counting optional?
I may be trying to generalize too much though :)

> Currently, the replication rpc that ships edits simply dumps the byte value
> of WAL edit key/value pairs into a protobuf message.
> Modify the replication rpc mechanism to use cell blocks so it can leverage
> encoding and compression.
