------------------------------------

             Summary: Add a library method that assigns unique Long values to vertices
                 Key: FLINK-2150
                 URL: https://issues.apache.org/jira/browse/FLINK-2150
             Project: Flink
          Issue Type: New Feature
          Components: Gelly
            Reporter: Vasia Kalavri
            Priority: Minor


In some graph algorithms, it is required to initialize the vertex values with unique values (e.g. label propagation).
This issue proposes adding a Gelly library method that receives an input graph and initializes its vertex values with unique Long values.
This method can then also be used to improve the MusicProfiles example.
