Subject [jira] [Created] (HAMA-919) Manage messages per Vertex
Date Tue, 16 Sep 2014 13:50:34 GMT
Edward J. Yoon created HAMA-919:

             Summary: Manage messages per Vertex
                 Key: HAMA-919
                 URL: https://issues.apache.org/jira/browse/HAMA-919
             Project: Hama
          Issue Type: Improvement
          Components: graph
    Affects Versions: 0.6.4
            Reporter: Edward J. Yoon
            Assignee: Edward J. Yoon
            Priority: Blocker
             Fix For: 0.7.0

As I described in mailing list, we need to manage the messages per Vertex. 

Currently, sender-side creates and sends the GraphJobMessage object per each message, receiver-side
groups messages by Vertex. To simplify grouping process, we used sorting and sequential processing.

If we manage the outgoing messages per Vertex, we don't need to use the sorted message queue.
So we can improve the memory efficiency and the performance by multi-threading.
