[jira] [Created] (GIRAPH-548) Reuse Edge objects in EdgeReader implementations

Alessandro Presta created GIRAPH-548:
----------------------------------------

             Summary: Reuse Edge objects in EdgeReader implementations
                 Key: GIRAPH-548
                 URL: https://issues.apache.org/jira/browse/GIRAPH-548
             Project: Giraph
          Issue Type: Improvement
            Reporter: Alessandro Presta
            Assignee: Alessandro Presta


Because read edges are serialized right away, we can actually reuse the same Edge object in each EdgeReader instance.
This behavior is currently optional in the Hive input formats, but it doesn't need to. It can also be adopted in other formats (e.g. PseudoRandomEdgeInputFormat).
