Brennon York commented on SPARK-4086: ------------------------------------- Hey [~ankurd] could you go into a little more detail about what methods you're actually thinking about here? Are you thinking we add a series of methods (like {{innerFoldJoin}}, {{leftFoldJoin}}, etc.) or modifying the existing methods to optionally take an additional parameter and act more like the fold operations? > Fold-style aggregation for VertexRDD > ------------------------------------ > > Key: SPARK-4086 > URL: https://issues.apache.org/jira/browse/SPARK-4086 > Project: Spark > Issue Type: Improvement > Components: GraphX > Reporter: Ankur Dave > Assignee: Ankur Dave > > VertexRDD currently supports creations and joins only through a reduce-style > interface where the user specifies how to merge two conflicting values. We > should also support a fold-style interface that takes a default value > (possibly of a different type than the input collection) and a fold function > specifying how to accumulate values. -- 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
