Abstract

The invention provides a method and device for determining a data comparison result, and equipment The method comprises the following steps that: data in a main table and an auxiliary table are loadedinto a data comparison table, wherein the table structure of the data comparison table comprises a main table field and a comparison field; the initial value of the comparison field corresponding toa row with the same data corresponding to the main table field in the data comparison table isupdated into a first numerical value, so that a first data comparison table is obtained; based on a main key field included in the main table field, rows of which comparison fields in the first data comparison table are not a first numerical value are grouped; the initial value of each row of comparison fields in each group is updated according to the number of rows included in each group, so that a second data comparison table is obtained; and a comparison result corresponding to each row of data inthe second data comparison table is determined according to a preset relationship between a comparison field value and the comparison result. By utilizing the method, device and equipment of the embodiment of the invention, full-table scanning can be avoided, and the comparison efficiency is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a method, device and equipment for determining data comparison results. Background technique [0002] In modern distributed systems, in order to improve the loading efficiency of data information and protect the integrity of data, data information often adopts a master-slave storage strategy, that is, multiple backups of data information are created to form a data master, and multiple Storage architecture for data replicas. As the master copy of the data changes, the data copy synchronizes the change records of the master copy to be consistent with the master copy. However, during the process of data synchronization, due to abnormalities in network transmission or data synchronization, data differences in the primary copy may occur. Therefore, checking whether the primary copy data is consistent and analyzing differences is important to improve the loading efficiency o...
