------------------------------------
Summary: The vertex-centric SSSP example and library method send
unnecessary messages during the first superstep
Key: FLINK-3181
URL: https://issues.apache.org/jira/browse/FLINK-3181
Project: Flink
Issue Type: Improvement
Components: Gelly
Affects Versions: 0.10.0
Reporter: Vasia Kalavri
The result is correct, but the current implementation has unnecessary message
overhead in the first superstep. The Messaging function should only produce
messages from the source during the first superstep. This can be fixed with a
simple check of the vertex value.
