I have a composite key consisting of: (integer, bytes) and I have rows like:
(1,abc), (1,def), (2,abc), (2,def) and I want to find all rows with the integer part = 2.

I need to create a startBeyondName using CompositeType.Builder class and am wondering if specifying (2, Bytes.Empty) will sort correctly?

I think another way of saying this is: "does HeapByteBuffer with pos=,lim=0,cap=0 sort prior to any other possible HeapByteBuffer?
