             Summary: Improve flow-control on sender side
                 Key: GIRAPH-1027
                 URL: https://issues.apache.org/jira/browse/GIRAPH-1027
             Project: Giraph
          Issue Type: Improvement
          Components: graph
            Reporter: Hassan Eslami
            Assignee: Hassan Eslami


Currently, a sender worker will keep all open requests (and optionally up to a certain number
of total open requests) in its own memory. This behavior may cause high memory usage in sender
side. Also, since messages can arrive to a worker at an arbitrary rate, receiver may not have
the ability to handle all incoming messages, hence we may see a large memory footprint in
receiver as well. This diff addresses the problem by limiting the number of open requests
per worker in sender side. Also, it provides a cache of unsent requests on sender in case
the sender already sent enough messages to another worker but has not received any response
back.
