There is not currently a way to page/scan/iterate through an individual column family, though this can certainly be emulated in your client code.
Part of the reason for that is that a single row, single family is stored within a single file. So there would be no significant savings in only retrieving part of the family at a time (besides network traffic). Looking forward, once we have our own storage format, like TFile, we will be able to do real/optimized scanning through a family of columns by retrieving them in chunks rather than all at once. Support of millions of columns within a single row, single family is one of the priorities but there are some other changes necessary before we can really get there.
