Publication number: 20230100110Abstract: A technique for computing resource management involves determining a first resource request frequency based on the number of trigger signals received from a storage device during a first period. The trigger signals are generated when a data amount of modified metadata stored in the storage device reaches a threshold data amount. The technique further involves determining a second resource request frequency based on the number of trigger signals received from the storage device during a second period subsequent to the first period. The technique further involves adjusting computing resources for performing an operation of copying the modified metadata in the storage device to a storage medium based on a comparison of the first resource request frequency and the second resource request frequency. Accordingly, computing resources can be fully utilized, and an operation of copying modified metadata to a magnetic disk can be timely performed.Type: ApplicationFiled: May 13, 2022Publication date: March 30, 2023Inventors: Ming Zhang, Chen Gong, Donglei Wang
