> During an unrelated test I found that when scanning a tall table with CQ only
> and filtering most results at the server, 50%(!) of time is spend in
> postScannerFilterRow, even though the coprocessor does nothing in that hook.
> We need to find a way not to call this hook when not needed, or to question
> why we have this hook at all.
> I think [~ram_krish] added the hook (or maybe [~anoop.hbase]). I am also not
> sure whether Phoenix uses this hook ([~giacomotaylor]?)
