A fairly developed work in progress for rgw qos is ongoing, using mclock and a set of request classifiers. This was discussed briefly at cephalocon. Exposing dmclock to higher (e.g. lb) tiers is also being discussed. Your requirements and ideas/help appreciated. In parallel, there is a pr in review which exposes the osd dmclock in librados. So there is not yet a fully integrated system in place, but a lot of detail to evaluate. Matt On Fri, Mar 30, 2018 at 5:53 AM, Will Zhao <zhao6305@xxxxxxxxx> wrote: > Hi : > My idea is like this.
