ADAPTIVE DATA RECOVERY FLOW CONTROL METHOD AND APPARATUS, ELECTRONIC DEVICE AND STORAGE MEDIUM

摘要

Provided is an adaptive data recovery flow control method, comprising: periodically synchronizing information of storage nodes in a distributed storage system (S11); when it is detected that a storage node fails (S12), acquiring a storage list of the failed storage node (S13); identifying an IO load category of a user application in a previous statistical period (S14); calculating, according to the IO load category in the previous statistical period, a flow control threshold value corresponding to the current statistical period (S15); according to the storage list and the flow control threshold value corresponding to the current statistical period, executing a recovery operation on data of the failed storage node in the current statistical period (S16); and determining whether the recovery operation is performed on the data of the failed storage node in all the statistical periods, and if so, ending the process (S17). Further provided are an adaptive data recovery flow control apparatus, an electronic device and a storage medium. According to the method, the obvious impact on a normal input and output service performance can be avoided, while the data recovery efficiency of the large-scale distributed storage system is improved and the data loss risk is reduced, and the method also has a good flow control effect.
