Subject Re: pagination through slices with deleted keys

+1.  There is some disagreement on whether or not the API should
return empty columns or skip rows when no data is found.  In all of
our use cases, we would prefer skipped rows.  And based on how
frequently new cassandra users appear to be confused about the current
behaviour, this might be a more common use case than the need for
empty cols.  Perhaps this could be added as an option on
SlicePredicate ?  (e.g. skipEmpty=true).
