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

             Summary: The load balancer of Saga may be faced with peak problem.
                 Key: SCB-751
                 URL: https://issues.apache.org/jira/browse/SCB-751
             Project: Apache ServiceComb
          Issue Type: Improvement
          Components: Saga
    Affects Versions: saga-0.2.0
         Environment: project: incubator-servicecomb-saga-0.2.0
            Reporter: Gannalyo


Currently, Saga's load balancer will *select a fastest 'MessageSender'* to send msg from pool.

My problem:
At some point, if every Alpha node need take 10 minutes to handle business for some reasons(e.g. network), that means, Saga will handle all following requests by the fastest 'MessageSender' within 10 minutes.
So, I think that the performance for Saga's load balancer will get a discount.

Of course, I believe one alpha node can handle many many requests. Just for improving Saga.

Part of code from LoadBalancedClusterMessageSender.java .... MessageSender messageSender = fastestSender(); try \{ long startTime = System.nanoTime(); AlphaResponse response = messageSender.send(event); senders.put(messageSender, System.nanoTime() - startTime); return response; } catch (OmegaException e) \{ throw e; }
