Lucas Bernardi commented on HBASE-4364:
---------------------------------------
How about specifying filterColumns explictly on the client side?
So if i want to do something equivalent to select a, b from x where c>0 and d<1
in hbase it would be
get.addColumn(a);
get.addColumn(b);
get.addFilterColumn(c);
get.addFilterColumn(d);
So the filter would only be applied on keyvalues for columns c and d.
If no filetrColumn is specified, then the filter would be applied on projected
columns only.
> Filters applied to columns not in the selected column list are ignored

> other columns which aren't selected, then those filter conditions are ignored.
