Abstract
A data processing method includes: after receiving an export request for exporting data from the distributed database, acquiring, by a database import and export management node an active transaction list and export table distribution information at a current moment; notifying, by the database import and export management node, a corresponding database that the corresponding database performs a data export operation according to the export table distribution information; after determining that the corresponding database completes the data export operation, sending, by the database import and export management node, the active transaction list to a database agent node of the corresponding database; and after receiving a data consistency reverse compensation statement returned by the database agent node, importing, by the database import and export management node, the data exported by the corresponding database into a predetermined database and instructing the predetermined database to execute the data consistency reverse compensation statement.
