Subject [jira] [Created] (SPARK-6281) Support incremental updates for Graph
Date Wed, 11 Mar 2015 08:36:39 GMT
Takeshi Yamamuro created SPARK-6281:
---------------------------------------

             Summary: 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.
