ASF GitHub Bot commented on FLINK-2012: --------------------------------------- Github user andralungu commented on the pull request: https://github.com/apache/flink/pull/678#issuecomment-105311774 Yes, I got the idea of difference, we agree on the functionality. What I was trying to say is that it cannot be used in the remove* methods as it needs to create a graph from an empty vertex set and that is impossible. If we want a difference method we should open a separate JIRA for that :) Tell me if I need to add anything else to this. Suggestion-wise, I think it's pretty balanced ^^ > addVertices, addEdges, removeVertices, removeEdges methods > ---------------------------------------------------------- > > Key: FLINK-2012 > URL: https://issues.apache.org/jira/browse/FLINK-2012 > Project: Flink > Issue Type: New Feature > Components: Gelly > Affects Versions: 0.9 > Reporter: Andra Lungu > Assignee: Andra Lungu > Priority: Minor > > Currently, Gelly only allows the addition/deletion of one vertex/edge at a > time. If a user would want to add two (or more) vertices, he/she would need > to add a vertex-> create a new graph; then add another vertex -> another > graph etc. > It would be nice to also have addVertices, addEdges, removeVertices, > removeEdges methods. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
