for RBD workloads you can set QOS values on a per image basis (and maybe on an
entire pool basis):

i'm not sure if you can do so for other workloads.

This only works if you reshard on the primary zone. Like Yixin, we've tried
resharding on the primary zone where data is held on a secondary zone and all

Hi,
What is the difference between using rgw compression vs enabling compression on
a pool? Is there any reason why you'd use one over the other for the data pool
of a zone?
