Yes, of course Giraph support dynamic graph mutation.
Graph mutation API is in Vertex class:
You can find some functions like addEdge, reomveEdge, addVertexRequest ...

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?
