Modify the priority and bandwidth Quality of Service (QoS) configurations for buckets and bucket groups in an OSS resource pool. This ensures that the minimum bandwidth commitment and priority rules comply with resource pool limits. - Object Storage Service

Call the PutResourcePoolPriorityQosConfiguration operation to modify the priority and Quality of Service (QoS) configurations for buckets and bucket groups in a resource pool.

Precautions

The number of priority levels must be between 3 and 10.
Priority levels start from 1. A higher number indicates a higher priority.
If you do not configure a default minimum bandwidth commitment (DefaultGuaranteedQosConfiguration), you must configure one for each priority level. If a default is configured, any priority level without a specific commitment will use the default value.
The sum of a minimum bandwidth commitment item (such as TotalUploadBandwidth) across all priority levels cannot exceed the value of the corresponding item in the resource pool.
A minimum bandwidth commitment for a priority level can be set to -1 only if the value of the corresponding item in the resource pool is -1.
If a bucket and its bucket group have different priority configurations, the bucket group's priority takes precedence.
