Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0042] During the recovery process, if there are many requests to access the distributed storage cluster, the data recovery process will affect the response speed and efficiency of the distributed storage cluster to front-end business requests, thereby reducing the external service capability; at the same time, the distributed storage cluster The response to front-end business requests will also affect the efficiency of data recovery and reduce the speed of data recovery. For this r...

Abstract

The invention discloses a data recovery method, device and equipment and a readable storage medium. The method disclosed by the invention is applied to any node in a distributed cluster, and comprisesthe steps of determining a local recovery speed according to a total data size and a cluster recovery speed if the total data size needing to be recovered is obtained, and recovering data according to the local recovery speed; in the recovery process, comparing the data processing amount of the current node for the service request in a preset time period with a first threshold value to obtain a first comparison result; and adjusting the local recovery speed according to the first comparison result, and continuing to recover the data according to the adjusted local recovery speed. According tothe method, the front-end service and the data recovery can be prevented from scrambling for computer resources, and the balance of the two can be realized, so that the response speed of the front-end service is increased, and the data recovery speed and efficiency are improved. The invention also discloses a data recovery device and equipment and the readable storage medium, which also have theabove technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data recovery method, device, equipment and readable storage medium. Background technique [0002] In the prior art, when the distributed storage cluster needs to restore data due to node failure or disk failure, it generally restores at a fixed recovery speed. During the recovery process, the distributed storage cluster can provide external services normally. During the recovery process, if there are many requests to access the distributed storage cluster, the data recovery process will affect the response speed and efficiency of the distributed storage cluster to front-end business requests, thereby reducing the external service capability; at the same time, the distributed storage cluster The response to front-end business requests will also affect the efficiency of data recovery and reduce the speed of data recovery. [0003] Therefore, in the process of data ...
