Hi,
there no guarantees for the fields other than the summed field (and
eventual key fields). I think in practice it's either the fields from the
first or last record but I wouldn't rely on that.

I am wondering about the expected behavior of the sum method. Obviously it
sums a specific field in a tuple or POJO. But what should one expect in
other fields? Does sum keep the first field, last field or there aren't
any guarantees?
