----------------------------------

             Summary: support succinct representation of messages in messagestores
                 Key: GIRAPH-912
                 URL: https://issues.apache.org/jira/browse/GIRAPH-912
             Project: Giraph
          Issue Type: Improvement
            Reporter: Pavan Kumar
            Assignee: Pavan Kumar


currently one-to-all messages is useful only for reducing network transfer, but at the server
side, before processingRequest, the messages are broken down into bytearrayvertexidmessages,
thus, each message is still stored as many times as the number of vertices it is sent to.


in this task we implements two message-stores that can represent messages in a very succinct
way
especially useful when messages are of significant size & fanout is low [note that this
is - useful only when no combiners are used]

this depends on GIRAPH-907 & GIRAPH-908
