Greg Hogan created FLINK-4963:
---------------------------------
Summary: Tabulate edge direction for directed VertexMetrics
Key: FLINK-4963
URL: https://issues.apache.org/jira/browse/FLINK-4963
Project: Flink
Issue Type: Improvement
Components: Gelly
Affects Versions: 1.2.0
Reporter: Greg Hogan
Assignee: Greg Hogan
Priority: Minor
The current implementation simply counts edges. We can do one better and
tabulate unidirectional (u:v but no v:u) and bidirectional edges (u:v and v:u).
This is effectively the ['dyadic
census'|http://file.scirp.org/pdf/SN_2013012915270187.pdf].
