stack commented on HBASE-14921:
-------------------------------
[~anoop.hbase] What you think of the [~ebortnik] proposal.
I just want to iterate that it is priority that the 80% case, the case where we
do not have much by way of Cell overlaps/duplicates, cannot suffer when we add
in this feature. It is fine if there is a temporary performance regression. We
can live with that in master branch, but it cannot go unaddressed. Just saying.
