Andrew Purtell commented on HBASE-11702:
----------------------------------------
bq. Number of bytes still important, right? (I'd say more important than Cell
count) For compaction we already get the length of each KV, can add to Flushes
as well. Followup jira? If you're tired of me asking I can add that
I'm not sure whether number of bytes or number of cells would be the more
useful metric but why not have both. No problem. Back with a new patch shortly.
