Hello, I created the JIRA issue at: https://issues.apache.org/jira/browse/FLINK-5506
Is it possible to submit suggestions to the documentation? If so, where can I do so? I actually did this based on the example at this page (possible Flink versions aside): https://flink.apache.org/news/2015/08/24/introducing-flink-gelly.html#use-case-music-profiles From the documentation I assumed that CommunityDetection has the same internal semantics as LabelPropagation (minus the algorithm difference itself) . It would be relevant to mention that it is not necessary to generate IDs (as in the music example) and that an undirected representation of the graph is generated before the algorithm being executed.
