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

             Summary: Make full use of Linux native libaio 
                 Key: ROCKETMQ-317
                 URL: https://issues.apache.org/jira/browse/ROCKETMQ-317
             Project: Apache RocketMQ
          Issue Type: Improvement
            Reporter: Zhanhui Li
            Assignee: vongosling


libaio is a library, developed as part of the Linux kernel project. With libaio, writes are submitted to the operating system where they are processed asynchronously. When the writes have been processed, the operating system calls the code back.

When messages being pulled were reclaimed out of main memory, making use of Linux native AIO system calls still allows zero-copy without blocking netty IO threads.
