Re: Lockup During Edge Saving

Looks like you're going out of memory, and it looks like it's your output format's fault. As you're using a CSV, I feel you're trying to build a single String line for each vertex, before you write it to HDFS. For vertices with many edges this string might get big, which could be one of your proble

Re: Dynamic graphs vs Graph Mutation

Khaled, 1) What exact functionality are you looking for? There isn't native Giraph support per se for time-evolving graphs in that sense (as far as I'm aware) but you should be able to simulate it in some fashion. 2) Check out AbstractComputation

Dynamic graphs vs Graph Mutation

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 verte
