Project: DistributedLog
Issue Type: Improvement
Components: distributedlog-client, distributedlog-core,
distributedlog-service
Affects Versions: 0.4.0, 0.5.0
Reporter: Liang Xie
Assignee: 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:)
