---------------------------------------------------------------------
This is sort of along the lines of what I was thinking, although I think just
adding a ColumnFamily index type would be adequate to distinguish it.
bq. column families which are sorted by the index value
This is the hard part, I am having trouble wrapping my mind around a scheme
that allows both different sort orders in different CFs and always routes
things correctly by node token no matter which CF you are talking about.
bq. which are queried using get_range_slices
As suggested by "adding a CF index type" I think using the same index query api
makes more sense.
