> Key: KYLIN-3417
> URL: https://issues.apache.org/jira/browse/KYLIN-3417
> Project: Kylin
> Issue Type: Improvement
> Reporter: Ted Yu
> Priority: Major
> Fix For: v2.5.0
>
>
> ReentrantReadWriteLock's are only the right solution when there is long hold
> time due to expensive I/O.
> It is expensive for readers.
> We should see if the lighter {{StampedLock}} can be used instead.
