That's FB's workaround for cassandra dealing poorly with mass insert /
data import.  The idea is you pre-serialize columnfamilies, and then
attach them to keys w/ binarymemtable which then stores them to
sstables w/o having to do any of the normal CF serialization work.
AFAIK nobody outside of FB has any sample code tho.
