without them overlapping/disturbing each other (assuming that keys lie in above domains) ?
Not sure what you mean by overlapping. 

42 as a int and 42 as a long are the same key.

I have been writing rows to a CF all with integer(4 byte) keys. So my CF contains rows with keys in the entire range from Integer.MIN_VALUE to Integer.MAX_VALUE. 

Now I want to store Long type keys as well in this CF **without disturbing the integer keys. The range of Long type keys would be excluding the integers's range ie  (-2^63  to -2^31) and (2^31 to 2^63). 

Would it be safe to mix the integer & long keys in single CF without them overlapping/disturbing each other (assuming that keys lie in above domains) ?
