Title:
METHOD AND APPARATUS FOR CREATING MATERIALIZED VIEW, AND STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/029855
Kind Code:
A1
Abstract:
The present disclosure relates to a method and apparatus for creating a materialized view, and a storage medium and an electronic device. The method comprises: extracting an original sub-query from a historical query statement; according to the original sub-query, generating a candidate query set in accordance with a preset rule; determining a target query from the candidate query set, wherein the target query is a query with a query gain greater than a preset gain threshold value; creating a materialized view corresponding to the target query, wherein the materialized view is used for processing a corresponding query. Since the target query is a query, in the candidate query set, with a query gain greater than the preset revenue threshold value, a hit rate of the materialized view can be improved; in addition, the materialized view is established only on the basis of the target query, such that the calculation cost and the storage cost of the materialized view can be reduced.
