Subject [jira] [Created] (FLINK-1633) Add getTriplets() Gelly method
Date Mon, 02 Mar 2015 21:52:06 GMT
Vasia Kalavri created FLINK-1633:

             Summary: 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
            Priority: Minor

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.
