             Summary: Allow configuration of # of disk I/O threads independently for solid-state and spinning disks
                 Key: IMPALA-5240
                 URL: https://issues.apache.org/jira/browse/IMPALA-5240
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.9.0
            Reporter: Tim Armstrong


Currently Impala defaults to 8 threads per SSD and 1 thread per spinning disk. This can be overridden with --num_threads_per_disk, but that sets the thread count independent of disk type. It would be nice to be able to override the two categories separately in anticipation of more exotic configurations with a mix of spinning disks and potentially high-performance SSDs that won't be maxed-out with 8 threads.
