-------------------------------------
@Ryan
Nice job!
I agree that we can't early out when we hit deleteFamily since we don't know if
there will be any DeleteColumn and Delete that is newer, is that what you are
saying too?
DeleteFamily doesn't have to be first on the row though, there might be some
columns with the null qualifier that sits before.
Don't really follow why the seek() method will not work.
The way I saw the problem with HBASE-867 was that we had two problems:
1. Scanning was too slow in general, since if you asked for all columns and not
explicit ones that query would time out too, which is really bad.
2. When asking for explicit column you would still have to next through all of
them even if you had them all for the current row, this is what seek() is
trying to help out with, by going back to the file and ask for the next row, so
we don't have too next through many blocks.
The thing with filters and gets is more of a Filter design issue. But I think
that if we rewrite Filters to fit them new implementation better I see no
problem in putting them in there, after all this is one of the things that we
wanted to accomplish with this rewrite.
