Abstract

The invention relates to a sub-table data merging method and device, electronic equipment and a computer readable medium. The method comprises the following steps: acquiring a plurality of basic sub-tables and corresponding log sub-tables; creating a target table according to the table structure of the basic sub-table and the source table field; performing data fusion on the plurality of basic sub-tables and the corresponding log sub-tables; inserting a data fusion result into the target table according to the source table field; and performing data merging on the target table. According to the sub-table data merging method and device, the electronic equipment and the computer readable medium, a large number of sub-tables can be rapidly and accurately subjected to data merging, the original data table used by the operation data layer of the data warehouse is generated, and the cost for creating and maintaining the original data table is reduced.

Description

technical field [0001] The present application relates to the field of computer information processing, and in particular, to a method, apparatus, electronic device, and computer-readable medium for data merging of sub-tables. Background technique [0002] With the development of cloud platforms, more and more enterprises now choose to use cloud platforms to provide data services. In cloud platforms, in order to ensure the speed of daily business processing, tables with large amounts of data are often divided into multiple sub-tables for storage. In the cloud platform, the table s of the business library is often divided into two tables for storage, such as the s_base (basic) table and the s_log (log) table. The s_base table stores the snapshot data of the current table s_base. The data will never change in the future, and the s_log table stores the log of each changed data in the table s_base. Every time the data is changed in s_base, two data will appear in the s_log tabl...
