[GitHub] [incubator-inlong] dockerzhang opened a new issue #832: [INLONG-233] Performance Improvement on FileSegmentList

[GitBox <gi...@apache.org>]

dockerzhang opened a new issue #832:
URL: https://github.com/apache/incubator-inlong/issues/832


   <p>Current implementation of FileSegmentList is based on <b>native compact array</b> (Object[]), so:<br/>
    1. it lacks flexibility on add/remove;<br/>
    2. it would suffer a great performance impact while applying CAS performing an operation;<br/>
    3. it may cause phantom read as multiple temporary copy of candidates may fail to announce its update due to unintended currentView change;<br/>
    4. less space efficiency, as there might be multiple temporary copies in system in order to do an update.</p>
   
   <p>So this issue is raised to optimize the storage list, and it's to exploit <b>RoundQueue</b> structure to achieve a better performance while make use of <b>weak CAS</b> to better adapt multi-threaded runtime.</p>
