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, 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|http://techieme.in/complex-graph-operations/].
This issue will focus on two frequently-used operators first: *union* and
*join*.
