Hello everyone, I tried writing my own code using Giraph and like it a lot but I have some questions regarding the input splinting and the partitioning of the graph.
1: Am I right in the assumption that Giraph does not split the input file by itself. Assume that I have got a graph in one single file, Giraph sends the whole graph to one worker while the rest of the workers is just idle. 2: I read through the source code and found a part saying that vertices must be presented in id-order. Is that a task the user has to do or is there a workaround to have vertices not in id-order? 3: The VertexRange class provides the assignment between vertices and workers. Is there a way to override the standard implementation and use a custom assignment system? Thanks in advance.
