[jira] [Created] (SPARK-7893) Complex Operators between Graphs

Andy Huang created SPARK-7893:
---------------------------------

             Summary: 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


Currently there are 30+ operators in GraphX. But 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, it will be helpful to operate between graphs directly, such as union or join, especially for streaming case, small graph and big graph. Higher level operators of graphs can help user to focus and think in graph.

As for details complex graph operator list, it can be found here:complex_graph_operations. We will focus on two frequently-used operators first: union and join.
