Apache Spark commented on SPARK-11496: -------------------------------------- User 'moustaki' has created a pull request for this issue: https://github.com/apache/spark/pull/14998 > Parallel implementation of personalized pagerank > ------------------------------------------------ > > Key: SPARK-11496 > URL: https://issues.apache.org/jira/browse/SPARK-11496 > Project: Spark > Issue Type: New Feature > Components: GraphX > Affects Versions: 2.1.0 > Reporter: Yves Raimond > Assignee: Yves Raimond > Priority: Minor > > The current implementation of personalized pagerank only supports one source > node. Most applications of personalized pagerank require to run the > propagation for multiple source nodes. However code such as: > {code} > sourceVertices.map { sourceVertex => > graph.staticPersonalizedPageRank(sourceVertex, 10) } > {code} > Will be very slow, as it needs to run 10 iterations * sourceVertices.size > propagation steps. > It would be good to offer an alternative API that runs personalized pagerank > over a list of source vertices in parallel, so that it only needs to run 10 > propagation steps in the example above. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
