Hi, I am fairly new to Spark GraphX. I am using graphx to create a graph derived from data size in the range of 500GB. The inputs used to create this large graph comes from a set of files with predefined space separated constructs. I also understand that each time, the graph will be constructed and kept in memory until the program terminates. The intention here is to create the large graph, then save only the required sub graphs on disk. My question is when the input set of files change, is it possible to update only those affected parts of the graph or does Spark have to recompute the entire graph in order to update the subgraphs? Thanks, Aarthi
