                 URL: https://issues.apache.org/jira/browse/DL-84
             Project: DistributedLog
          Issue Type: Improvement
          Components: distributedlog-client, distributedlog-core, distributedlog-service
    Affects Versions: 0.4.0, 0.5.0
            Reporter: Liang Xie

Reading code and finding that we use HashedWheelTimer in OwnershipCache Class, from netty HashedWheelTimer java doc we know:
{quote}
Do not create many instances.
HashedWheelTimer creates a new thread whenever it is instantiated and started. Therefore, you should make sure to create only one instance and share it across your application
{quote}
then i grep the code base and found more than ten HashedWheelTimer instantces be created seems. i think the current code could be improved to reduce the thread num:)
