-------------------------------------
@jgray
Yeah, it's is a little weird, cause when I pasted it, it looked really good in
the window, but now it looks really bad.
@Stack
Not really sure what is considered to be very different, I do think that the
difference is quite big
The only methods that stays pretty much the same is reset() and filterColumn
which changes name to filterQualifier since we are trying to get rid of the
column notion.
The filterRowKey could be used as filterRow, but since we only take a byte[] as
input we can't use the KeyValue from the scanners but have to do a copy for
every check, which seems like
an unnecessary thing to do, specially since the whole plan on the server side
is to avoid copying.
I'm not dying to rewrite the filters, but have started, cause I don't really
seem how we could use the old ones in a good way, but if you see a way for us
to do that, I'm happy to not do the work.
