--------------------------------
Resolution: Not A Problem
> accepting NullValue for VV in Gelly examples and GSA
> ----------------------------------------------------
>
> Key: FLINK-5161
> URL: https://issues.apache.org/jira/browse/FLINK-5161
> Project: Flink
> Issue Type: Improvement
> Components: Gelly
> Affects Versions: 1.1.3
> Reporter: wouter ligtenberg
>
> I made this topic a few days ago about EV, i meant VV back then, i don't know
> why i suddenly thought about EV and it confused myself.
> In this gelly example [1] and this GSA algorithm [2] a Vertex Value of Double
> is required but never used, wouldn't it be better to change this into a
> NullValue? I create a lot of data without Vertex Values and it seems to me
> that it's more efficient
> I'd like to hear your thoughts on this
