Graph Mutation

Hi,

I have a need to add some additional nodes in the graph, after a few supersteps in my algorithm.

As per the Pregel paper it is allowed. Will that be feasible in Giraph ?

If yes, how does it work?

Thanks. I was a bit late in trying this. But it worked beautifully well.

In fact later I had found that in Giraph examples there is a class which show how to use there APIs.

See Computation for how to mutate the graph:

addVertexRequest
removeVertexRequest
addEdgeRequest
removeEdgeRequest
