Joseph K. Bradley commented on SPARK-7893: ------------------------------------------ I guess I'm OK with keeping an umbrella JIRA since I like organization in JIRA. But we should make sure to consider & justify each operation so that we prioritize ones which many users really need. > Complex Operators between Graphs > -------------------------------- > > Key: SPARK-7893 > URL: https://issues.apache.org/jira/browse/SPARK-7893 > Project: Spark > Issue Type: Improvement > Components: GraphX > Reporter: Andy Huang > Labels: complex, graph, join, operators, union > > Currently there are 30+ operators in GraphX, while few of them consider > operators between graphs. The only one is _*mask*_, which takes another graph > as a parameter and return a new graph. > In many complex case,such as _*streaming graph, small graph merge into huge > graph*_, higher level operators of graphs can help users to focus and think > in graph. Performance optimization can be done internally and be transparent > to them. > Complex graph operator list is > here:[complex_graph_operations|http://techieme.in/complex-graph-operations/] > * Union of Graphs ( G ∪ H ) > * Intersection of Graphs( G ∩ H) > * Graph Join > * Difference of Graphs(G – H) > * Graph Complement > * Line Graph ( L(G) ) > This issue will be index of all these operators -- 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
