> Right now, whenever we get back multiple cells worth of data at a time, we do
> so in a map of HStoreKey->byte[]. This means that there is a duplicated Text
> row and long timestamp at the very least between every cell. This is quite a
> bit wasted. It also means we have to do a lot of translation every time.
> We could create a new Writable that contains just one row, one timestamp, and
> a map of Text->byte[].
