Subject [jira] [Created] (GIRAPH-185) Improve concurrency of putMsg / putMsgList
Date Tue, 17 Apr 2012 20:47:17 GMT
Improve concurrency of putMsg / putMsgList
------------------------------------------

                 Key: GIRAPH-185
                 URL: https://issues.apache.org/jira/browse/GIRAPH-185
             Project: Giraph
          Issue Type: Improvement
          Components: graph
    Affects Versions: 0.2.0
            Reporter: Bo Wang
             Fix For: 0.2.0


Currently in putMsg / putMsgList, a synchronized closure is used to protect the whole transientInMessages
when adding the new message. This lock prevents other concurrent calls to putMsg/putMsgList
and increases the response time. We should use fine-grain locks to allow high concurrency
in message communication.
