Abstract

The invention discloses a method, an apparatus, a device and a computer-readable storage medium for controlling the data recovery speed. The method comprises the following steps: determining a corresponding cluster recovery speed based on the current busy degree of a distributed system; determining a corresponding cluster recovery speed based on the current busy degree of the distributed system; determining any storage node to recover data as a target node, multiplying the ratio of the number of data to be recovered by the target node and the number of data to be recovered by the distributed system by the cluster recovery speed to obtain the recovery speed of the corresponding node, and determining the number of tokens allocated to the target node in a unit time as the currently availablenumber of tokens based on the recovery speed of the node; when the data recovery request is received, judging whether the number of tokens allocated to the target node in the current unit time reachesthe currently available number of tokens, if so, refusing issuing of the token to the target node, if not, issuing the token to the target node to indicate that the target node realizes the data recovery. The invention achieves the purpose of controlling the speed of data recovery based on the current situation of the distributed system.

Description

technical field [0001] The present invention relates to the technical field of distributed storage systems, and more specifically, to a method, device, device and computer-readable storage medium for controlling data restoration speed. Background technique [0002] With the rise and popularization of cloud computing technology, distributed storage systems have begun to attract more and more attention from the industry. In a distributed storage system, if there is data corruption or data loss, it is necessary to obtain data from the corresponding backup to achieve data recovery. Usually, in order to avoid data loss, it is necessary to complete data recovery and balance as soon as possible, but data recovery usually affects distributed storage. The performance of the system has a certain impact, which may affect business access. Therefore, if the data recovery speed can be controlled to meet the current situation of the distributed storage system, the above two problems can be...
