Abstract: Embodiments of the present application provide a data processing method and apparatus, an electronic device, and a storage medium. The data processing method, applied to a first participating node, includes: encrypting plaintext service data based on an encryption key array to obtain a ciphertext data set, where the ciphertext data set includes ciphertext service data, and different participating member nodes use a same encryption key array; sending the ciphertext data set to a central node; and acquiring a data comparison result generated by the central node, where the data comparison result is obtained by performing data comparison based on ciphertext service data in ciphertext data sets of the participating member nodes.

Abstract: A data processing method. In the method, a target transaction change log of each database sub-library among a plurality of database sub-libraries is acquired and parsed. The target transaction change log is a most recently generated transaction change log in the database sub-library. If an event type indicated by the target transaction change log is a Data Definition Languages (DDL) event, information of the DDL event, which has been recorded in the target transaction change log, is recorded in a target event slot corresponding to the DDL event.
