----------------------------------
Summary: Graph getUndirected improvement
Key: FLINK-1975
URL: https://issues.apache.org/jira/browse/FLINK-1975
Project: Flink
Issue Type: Improvement
Components: Gelly
Affects Versions: 0.9
Reporter: Andra Lungu
Assignee: Andra Lungu
Priority: Minor
The current getUndirected method uses a union and a map to add the reverse
edges to the graph. This could be done by simply using a flatMap that adds the
edge and its reversed version - a flatMap is less expensive than a union
followed by a map.
