Abstract

The invention relates to a log synchronization method and device, a computer readable storage medium and electronic equipment, and relates to the technical field of computers. The method comprises the following steps: obtaining a to-be-matched log list and a target log list corresponding to the to-be-matched log list, and determining current to-be-matched logs included in the to-be-matched log list; determining whether the current to-be-matched log is matched with the target log list or not according to the current to-be-matched log and the target log list; when it is determined that the current to-be-matched logs are not matched with the target log list, according to the target log list, determining to-be-matched logs matched with the target log list in the to-be-matched log list; and based on the to-be-matched log, synchronizing the to-be-matched log to the target log list. The log backspacing frequency is reduced, and the log synchronization efficiency is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technologies, and in particular, relate to a log synchronization method, a log synchronization device, a computer-readable storage medium, and electronic equipment. Background technique [0002] In a distributed system, a consensus protocol is used to maintain the same state among multiple nodes. Among them, the Raft protocol is widely used because it is easy to understand. [0003] In the implementation of the basic Raft protocol, when the log list to be matched by the leader node synchronizes logs with the target log list of the follower node, and the current log to be matched in the log list to be matched does not match the target log list, usually Perform a "return one" operation on the list of logs to be matched, that is, use the previous log of the current log to be matched as the matching log for the next synchronization. success. [0004] However, the leader node and the fo...
