Fault recovery method and device, electronic equipment and computer readable storage medium

The embodiment of the invention discloses a fault recovery method and device, electronic equipment and a computer readable storage medium. The fault recovery method comprises the steps of obtaining latest snapshot data of a fault node in response to a fault recovery event of the fault node; wherein the snapshot data at least comprises the state of the fault node and input and output information atthe last snapshot moment; recovering the state of the fault node at the last snapshot moment according to the snapshot data, and processing input data according to a mode before the fault of the fault node to obtain a processing result; outputting target data in the processing result; wherein the target data are data which are not obtained by a downstream node of the fault node. According to theinvention, data consistency before and after fault recovery can be realized, and single-point recovery of the failure node can be realized without global rollback, so that the real-time performance offault recovery can be ensu
