> Key: IMPALA-10695
> URL: https://issues.apache.org/jira/browse/IMPALA-10695
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Yong Yang
> Assignee: Yong Yang
> Priority: Critical
>
> So far, the S3A, Adls and ABFS have dedicate queues in impala IO path. Ali
> cloud has similar target, like oss and jfs.
> To improve the query IO performance when target files are stored in oss/jfs,
> it is necessary to create a dedicate queue for that.
>
> BTW, I have some code ready for that when I am optimizing this situation.
> Please share your opinion if I should commit that part code.
