1. A service flow control method in an object-based storage system comprising a controller and a storage device client, the method comprising:

  • receiving, by the controller, a first object IO request;

    acquiring, by the controller a processing quantity threshold and a to-be-processed quantity, wherein the processing quantity threshold is a threshold of a quantity of object IO requests to be processed by the object-based storage system, and the to-be-processed quantity is a quantity of to-be-processed object IO requests in the object-based storage system;

    when the to-be-processed quantity is less than the processing quantity threshold, sending, by the controller, the first object IO request to the storage device client, and updating the to-be-processed quantity;

    receiving, by the controller, a first response message from the storage device client in response to the first object IO request, wherein the first response message carries a processing result of the first object IO request; and

    adjusting the processing quantity threshold according to a received processing result of an object IO request when a preset condition is met.
