hello, I was wondering if there was a way to ensure that vertices located on the same data block (on hdfs) are co-located with each other?
Also, will the vertices in input-splits (splits that are located on the same DataNode) have a reasonable chance of being partitioned to the same id? for example, suppose that I have vertex_1 located on data_block_i, and vertex_2 located on data_block_k. Let's suppose that both of the data blocks are located on the same DataNode machine. Is there a reasonably good chance that the vertex_1 and vertex_2 will partition to the same id? I'm doing a research project and I'm trying to show the benefits of graph data-locality. -David
