[jira] [Created] (GIRAPH-1189) PageRank: make the use of one-to-many messaging configurable

Dionysios Logothetis created GIRAPH-1189:
--------------------------------------------

             Summary: PageRank: make the use of one-to-many messaging configurable
                 Key: GIRAPH-1189
                 URL: https://issues.apache.org/jira/browse/GIRAPH-1189
             Project: Giraph
          Issue Type: Improvement
            Reporter: Dionysios Logothetis


The PageRank implementation uses one-to-many messaging to reduce the amount of traffic sent. The corresponding message request (SendWorkerOneMessageToManyRequest)  creates ByteArrayVertexIdMessages instances before adding the messages to the Message Store. When the number of messages is big, the creation of this instances can fail. 

Adding an option here to enable/disable the use of one-to-many messaging.
