func DefaultMemoryQOS

func DefaultMemoryQOS(qos apiext.QoSClass) *slov1alpha1.MemoryQOS

DefaultMemoryQOS returns the recommended configuration for memory qos strategy. Please refer to `apis/slo/v1alpha1` for the definition of each field. In the recommended configuration, all abilities of memcg qos are disable, including `MinLimitPercent`, `LowLimitPercent`, `ThrottlingPercent` since they are not fully beneficial to all scenarios. Whereas, they are still useful when the use case is determined. e.g. lock some memory to improve file read performance. Asynchronous memory reclaim is enabled by default to alleviate the direct reclaim pressure, including `WmarkRatio` and `WmarkScalePermill`. The watermark of async reclaim is not recommended to set too low, since lower the watermark the more excess reclamations. Memory min watermark grading corresponding to `WmarkMinAdj` is enabled. It benefits high-priority pods by postponing global reclaim when machine's free memory is below than `/proc/sys/vm/min_free_kbytes`.
