Hi @tillrohrmann ,
For the log2 part, you mean something like this: ceil(log2(x)) = 32 -
numberOfLeadingZeros(x - 1)? 32 because it's int, in this case it should be
64...
I started with gelly because I thought it would be nice to first break
stuff in my own part of the woods :). I am in favour of generalising. What
should we change for that?
> 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
> Assignee: Andra Lungu
> Priority: Minor
> Labels: starter
>
> 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.
