Assignee: Ankur Dave
Simplify Pregel by merging joins
Key: SPARK-9436
URL: https://issues.apache.org/jira/browse/SPARK-9436
Project: Spark
Issue Type: Improvement
Components: GraphX
Affects Versions: 1.4.0
Reporter: Alexander Ulanov
Assignee: Ankur Dave
Priority: Minor
Fix For: 1.5.0
Original Estimate: 1h
Remaining Estimate: 1h
Pregel code contains two consecutive joins:
```
g.vertices.innerJoin(messages)(vprog)
...
g = g.outerJoinVertices(newVerts) { (vid, old, newOpt) =
newOpt.getOrElse(old) }
```
They can be replaced by one join. Ankur Dave proposed a patch based on our
discussion in mailing list:
