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 user to focus and think in
graph.
Complex graph operator list is
here:[complex_graph_operations|http://techieme.in/complex-graph-operations/].
This issue will focus on two frequently-used operators first: *union* and
*join*.

In many complex case,such as _*streaming graph, small graph merge into big
graph*_,complex operators will be helpful to operate between graphs directly.
Higher level operators of graphs can help user to focus and think in graph.
