------------------------------

Hi I see the issue as resolved and the resolution as wont fix!
I am currently using GraphX and I also have this requirement of updating the graph incrementally specially adding new edges and deletion of old edges. Is it possible in current version some how? currently As i understood this could be done only by doing a union of the new edge RDDs with the graph.Edge RDDs and creating the graph again which does not seem very efficient as the new edges arrives in stream at quit frequent interval. Any plans of supporting this in future?

> Add api to efficiently append new vertices and edges into existing Graph,
> e.g., Graph#append(newVerts: RDD[(VertexId, VD)], newEdges: RDD[Edge[ED]], defaultVertexAttr: VD)
> This is useful for time-evolving graphs; new vertices and edges are built from
> streaming data thru Spark Streaming, and then incrementally appended
> into a existing graph.
