Github user mushketyk commented on the issue: https://github.com/apache/flink/pull/2564 Tuple8 does not seem to friendly to me either. What do you mean by "attaching the labels"? Is it something similar to what we do with Edge/Vertex classes right, inheriting Tuple and providing getters and setters to access values in it? Or is there some other way to attach labels to tuples?
