Class GraphMetrics$

java.lang.Object

org.apache.flink.graph.scala.examples.GraphMetrics$

public class GraphMetrics$
extends Object

This example illustrates how to use Gelly metrics methods and get simple statistics from the input graph.

The program creates a random graph and computes and prints the following metrics: - number of vertices - number of edges - average node degree - the vertex ids with the max/min in- and out-degrees

The input file is expected to contain one edge per line, with long IDs and no values, in the following format:

   <sourceVertexID>\t<targetVertexID>
 

If no arguments are provided, the example runs with a random graph of 100 vertices.
