Thanks for implementing this @andralungu!
I have added some inline comments.
Also, we are definitely missing documentation and an example using the
method.
I would suggest something simple, like weighting an input graph, by
computing the euclidean distance of the src/vertex values for each edge and
attaching this value as the edge weight.
What do you think?
> Add getTriplets() Gelly method

> Key: FLINK-1633
> URL: https://issues.apache.org/jira/browse/FLINK-1633
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 0.9
> Reporter: Vasia Kalavri
> Assignee: Andra Lungu
> Priority: Minor
> Labels: starter
>
> In some graph algorithms, it is required to access the graph edges together
> with the vertex values of the source and target vertices. For example,
> several graph weighting schemes compute some kind of similarity weights for
> edges, based on the attributes of the source and target vertices. This issue
> proposes adding a convenience Gelly method that generates a DataSet of
> <srcVertex, Edge, TrgVertex> triplets from the input graph.
