Review comment:
Key columns must always be set.
Otherwise, Tuple can't be used in Map<Tuple, Tuple>, due to a key may have
different representation.
Assume, you call KvView.getAll() and them try to find a key in the map.
KvView.getAll() will return key-tuples with all the columns (with default
values), but the user key-tuple may miss some columns.
