Github user andralungu commented on the pull request: https://github.com/apache/flink/pull/537#issuecomment-87425953 Hi @vasia , 1). I will add the documentation once we reach a consensus. No use documenting something that might change :) 2). For the public setter: I still couldn't think of a workaround. Waiting for suggestions. 3). Most of the comments were addressed in this final commit, however, when speaking about avoiding unnecessary overhead, the only way I could do that is to add another VertexCentricIteration class that operates on Tuple3 and have the user decide from the constructor which class he/she wants to use. To me that seems to introduce a ton of duplicate code which will look very bad. Keeping in mind that I need to store the degrees in the vertex value, any suggestions on how to eliminate this overhead would be very useful. Thanks!
