Subject [jira] [Updated] (SPARK-7893) Complex Operators between Graphs
Date Wed, 27 May 2015 09:53:17 GMT

     [ https://issues.apache.org/jira/browse/SPARK-7893?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andy Huang updated SPARK-7893:
------------------------------
    Description: 
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](http://techieme.in/complex-graph-operations/).
This issue will focus on two frequently-used operators first: *union* and *join*.
