Problems solved by technology

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 effectively avoided. However, the existing technology does not There is no technical solution that can achieve the above purpose

Abstract

The invention discloses a method, device, device and computer-readable storage medium for controlling data recovery speed. The method includes: determining the corresponding cluster recovery speed based on the current busyness of the distributed system; The node is the target node. Multiply the ratio of the number of data to be restored by the target node to the number of data to be restored in the distributed system by the cluster recovery speed to obtain the corresponding node recovery speed, and determine the token allocated to the target node per unit time based on the node recovery speed The number is the number of currently available tokens; when receiving a data recovery request, judge whether the number of tokens allocated to the target node in the current unit time reaches the number of currently available tokens, and if so, refuse to issue tokens for the target node, if If not, a token is issued for the target node to instruct the target node to realize data recovery. To achieve 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...
