["Joseph K. Bradley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-7893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14567799#comment-14567799 ] 

Joseph K. Bradley commented on SPARK-7893:
------------------------------------------

I agree.  Also, it will be important to provide use cases for these operations to understand how to prioritize them.

>                 URL: https://issues.apache.org/jira/browse/SPARK-7893
>             Project: Spark
>          Issue Type: Improvement
>          Components: GraphX
>            Reporter: Andy Huang
>              Labels: complex, graph, join, operators, union

> 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/]. This issue will focus on two frequently-used operators first: *union* and *join*.
