---------------------------------
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.
