Hi! The order in which the elements arrive in an iteration HEAD is the order in which the last operator in the loop (the TAIL) produces them. If that is a deterministic ordering (because of a sorted reduce, for example), then you should be able to rely on the order. Otherwise, the order of elemen

Hi, as I understand it the order of elements will not be preserved across iteration supersets. But maybe some-one else knows more. Cheers, Aljoscha On Thu, 28 Apr 2016 at 00:23 David Kim wrote: > Hello all, > > I read the documentation at [1] on iterations and had a question on > whether an ass

Flink Iterations Ordering

2016-04-27 Thread David Kim
Hello all, I read the documentation at [1] on iterations and had a question on whether an assumption is safe to make. As partial solutions are continuously looping through the step function, when new elements are added as iteration inputs will the insertion order of all of the elements be preserv
