Log analysis method, data synchronization system, electronic equipment and storage medium

The invention discloses a log analysis method, a data synchronization system, electronic equipment and a storage medium, and the method comprises the steps: obtaining first metadata information at a first time from a source database, and verifying the first metadata information with locally stored second metadata information at a second time, the second metadata information is information after the first metadata information executes the specified instruction; under the condition of verification failure, analyzing the incremental log from the first time to the second time to obtain a specified instruction; obtaining a reverse instruction corresponding to the specified instruction to obtain a corresponding target instruction; acquiring third metadata information according to the second metadata information and the target instruction, and replacing the second metadata information with the third metadata information to pass verification; according to the third metadata information, the log of the first time is a
