----------------------------------
Summary: reduce degree recomputation in StronglyConnectedComponents
Key: SPARK-30432
URL: https://issues.apache.org/jira/browse/SPARK-30432
Project: Spark
Issue Type: Improvement
Components: GraphX
Affects Versions: 2.4.4, 2.4.5, 3.0.0
Reporter: li xiaosen
Fix For: 2.4.4
It would be helpful when computing StronglyConnectedComponents to reduce degree
computation.
I have done a small code proposal, because there is a problem when the pregel
executions have done, the degree no need to be recomputed.
I created a branch in my fork:
[https://github.com/xs-li/spark/blob/branch-2.4/graphx/src/main/scala/org/apache/spark/graphx/lib/StronglyConnectedComponents.scala]
I hope you can consider this small code proposal.
Thank you very much,
Best regards,
xs-li
