Hi : My idea is like this. Because I don't need the QoS to be very accurate. So I can write some script in load balancer layer, to add ρi and δi value in the request header, and then pass it to rgw backend. So I think I can add QoS on both the IOPS and bitrate based on user access key. This maybe not the best way, but is a simple way. Does anyone has a better idea ? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
