The tested algorithm program has no perception of the data analysis process, does not affect the business, and saves large-scale Cluster test algorithm debugging and analysis time.

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.
