Vladimir Rodionov commented on HBASE-9769:
------------------------------------------
1. Its not a client side filter (keeps only column qualifiers - no column
families). I decided to put it into regionserver, but I can move to hbase-client
2. OK, shouldUse is better
3. you right this check is not needed.
I will add tests, of course.
> Improve performance of a Scanner with explicit column list when rows are
