Subject [jira] Created: (HADOOP-2975) IPC server should not allocate a buffer for each request
Date Sat, 08 Mar 2008 00:05:46 GMT
IPC server should not allocate a buffer for each request
--------------------------------------------------------

                 Key: HADOOP-2975
                 URL: https://issues.apache.org/jira/browse/HADOOP-2975
             Project: Hadoop Core
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 0.16.0
            Reporter: Hairong Kuang
             Fix For: 0.17.0


Currently the IPC server allocates a buffer for each incoming request. The buffer is thrown
away after the request is serialized. This leads to very inefficient heap utilization. It
would be nicer if all requests from one connection could share a same common buffer since
the ipc server has only one request is being read from a socket at a time.
