Re: WindowedStream sum behavior

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. Cheers, Aljoscha On Sat, 9 Apr 2016 at 03:19 Elias Levy wrote: > I am

WindowedStream sum behavior

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?
