Yes, of course Giraph support dynamic graph mutation. Graph mutation API is in Vertex class: https://github.com/apache/giraph/blob/release-1.0/giraph-core/src/main/java/org/apache/giraph/graph/Vertex.java You can find some functions like addEdge, reomveEdge, addVertexRequest ...
Thanks, Zhang, David -----Original Message----- From: Khaled Ammar [mailto:[email protected]] Sent: 2014年9月16日 1:37 To: [email protected] Subject: Dynamic graphs vs Graph mutations! Hi all, I understand that Pregel supports graph mutations when vertices issue requests to make changes in the graph topology (add/remove vertex/edge). I have two questions here: 1- Does the same concept applies to supporting dynamic graphs? (Graphs that change over time where the add/remove vertex/edge is read from a file instead of being generated by the vertex?) 2- Which class/function handles graph mutations in the source code? Thanks, -Khaled
