Edward Bortnikov commented on HBASE-14921:
------------------------------------------
Thanks, all, for the last round ... Seems like we are converging.
So, we seem to agree on the following:
1. At the end of the day, we want compaction (data de-duplication) where it
helps, and don't want it where it doesn't. That might use a flag or some smart
policy. Getting there might take 1-2 more (smaller) patches.
2. We want to land the current patch because it's getting big. The mandatory
condition for passing it is bug-freedom (via improved coverage), including the
more stressful PE tests. Hopeful to finish this week or early next week.
3. We want to release all the dependencies for [~anoop.hbase] and [~ram_krish]
on their way to off-heap memory implementation. We'll switch to that as soon as
the current patch is landed. We have a common goal (smile).
Deal?
