> Key: KYLIN-4653
> URL: https://issues.apache.org/jira/browse/KYLIN-4653
> Project: Kylin
> Issue Type: Improvement
> Reporter: Zhong Yanghong
> Assignee: Zhong Yanghong
> Priority: Major
> Fix For: v3.1.1
>
>
> Currently the blocking queue capacity is 50K. It is too small, which easily goes into being blocked and slows down queries.
> It's better to make this value configurable and enlarge the default value.
> For real usage, I strongly recommend to use unbounded LinkedBlockingQueue, which is supposed not to block queries due to report query metrics.
