Abstract: A data persistence processing method is disclosed, where the method includes: adding the dirty page identifier to a checkpoint queue each time when a dirty page is generated in a database system memory; determining an active group and a current group in the checkpoint queue, and successively dumping, to a disk, the dirty pages corresponding to the active group on a preset checkpoint occurrence occasion, where the dirty pages are currently prepare to be dumped to the disk, and a group inserted with a dirty page that is newly added is the current group; and determining a next active group if last dumping is completed, and successively dumping, to the disk, the dirty pages corresponding to the next active group on the checkpoint occurrence occasion. The method improves the dumping efficiency of the dirty pages.
