Andy Huang updated SPARK-7893:
------------------------------
Description:
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 issue will focus on two frequently-used operators first: *union* and
*join*.
