Abstract: A method includes identifying a quality of service (QoS) policy associated with a tenant in view of a tenant identifier. The QoS policy includes a threshold value of a performance parameter. The method also includes receiving a service request from the tenant, estimating, in view of a subset of a plurality of historical records, an impact value indicating an impact of the service request on the performance parameter of the distributed storage system, determining, in view of the impact value, an estimated value of the performance parameter to result from servicing the service request of the tenant, and responsive to an evaluation of the estimated value of the performance parameter in view of the threshold value of the performance parameter, allocating computing resources of the multi-tenant distributed storage system to execute an operation associated with the service request.

Abstract: A method is provided that includes receiving a tenant identifier. The method also includes identifying a quality of service (QoS) policy associated with a tenant identified by the tenant identifier, by looking up the tenant identifier in a memory data structure. The QoS policy includes a threshold value of a performance parameter. The threshold value is a minimum or a maximum threshold value. The method also includes receiving a service request from the tenant. The method also includes determining an estimated value of the performance parameter in view of the request. The method also includes, responsive to successfully evaluating a validity condition with respect to the estimated value in view of the threshold value, forwarding the request to a servicing component for execution. The validity condition is provided by the estimated value not exceeding the maximum threshold value or the estimated value not falling below the minimum threshold value.
