> Support incremental updates for Graph
> -------------------------------------
>
> Key: SPARK-6281
> URL: https://issues.apache.org/jira/browse/SPARK-6281
> Project: Spark
> Issue Type: New Feature
> Components: GraphX
> Reporter: Takeshi Yamamuro
> Priority: Minor
>
> 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.
