Subject Re: Incrementally add/remove vertices in GraphX
Date Mon, 17 Mar 2014 16:50:22 GMT
Hi All,

Is somebody looking into this?
I think this is correlated with the discussion "Are there any plans to
develop Graphx Streaming?".

Using union / subtract on VertexRDD or EdgeRDD leads on the creation of new
RDD but NOT in the modification of the RDD in the graph.
Is creating a new graph the only way to go to add /remove vertex or edge?

Thanks
Alessandro
