    Description

      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.
