Abstract

The invention discloses a method, a device, an apparatus and a computer readable storage medium for adjusting data recovery speed based on object read/write time delay. The method comprises the following steps: receiving a data recovery request, determining any storage node in a distributed system that needs to realize data recovery as a target node, and performing data recovery of the target nodeaccording to a preset data recovery speed of the target node; and performing data recovery of the target node according to the preset data recovery speed of the target node; obtaining the current object read/write delay of the target node, judging whether the current object read/write delay is greater than the preset delay threshold of the target node, if so, decreasing the data recovery speed ofthe target node for data recovery, if not, determining that the data recovery speed of the target node for data recovery does not need to be changed. As a result, when the data restoration has adverse effects on the data access service, the speed of the data restoration is reduced to ensure the normal data access service, and when the data restoration has no adverse effects on the data access service, the fast data restoration is realized.

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 adjusting data recovery speed based on object read and write delays. 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 data is damaged or lost, 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 has a certain impact on the performance of the distributed storage system, which in turn may affect the data access business. [0003] To sum up, there is a problem that the technical solutions for realizing data recovery in the prior art may ca...
