Bikramjeet Vig has uploaded a new patch set (#2). Change subject: IMPALA-5240: Allow config of number of disk I/O threads per disk type ......................................................................
IMPALA-5240: Allow config of number of disk I/O threads per disk type Currently Impala defaults to 8 threads per flash disk and 1 thread per rotational disk. This can be overridden with --num_threads_per_disk, but that sets the thread count independent of disk type. This would allow control of the number of disk I/O threads spawned independently for solid state disks using "--num_io_threads_per_solid_state_disk" and for rotational disks using "--num_io_threads_per_rotational_disk" as startup parameters. Testing: Tested manually. Unfortunately, there is no way using DiskIoMgr class to confirm these variables were set, therefore no automated backend tests were added.
