Problems solved by technology

With the development of database technology, the database market is showing a trend of diversification. There are more and more types of databases that can be used. However, the current index optimization and recommendation are usually set inside a certain database and are only applicable to this database or the same database. type of database, which makes index optimization and recommendation unable to be generalized, and brings inconvenience to index optimization and recommendation

Abstract

The embodiment of the invention discloses a query data processing method and device, electronic equipment and a computer storage medium. The method comprises the steps: obtaining to-be-processed querydata, and splitting the to-be-processed query data into at least two to-be-processed query sub-data; generating a corresponding candidate index data combination based on the to-be-processed query sub-data, and performing cost evaluation on the candidate index data combination according to a target database type of the to-be-processed query data to obtain target index data corresponding to the to-be-processed query sub-data; and performing merging processing on the target index data corresponding to different to-be-processed query sub-data to obtain a processing result of the to-be-processed query data. According to the technical scheme, the universality degree of index optimization is improved, and the great convenience is brought to the use of index optimization. The working efficiency of index optimization is improved, and the calculation resources of index optimization are saved.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of data processing, and in particular to a query data processing method, device, electronic equipment, and computer storage medium. Background technique [0002] In the database field, index optimization and recommendation are an important part of database performance optimization. Index optimization and recommendation refer to services that provide optimization and recommendation suggestions for one or more input query statements in a short period of time. With the help of index optimization and recommendation services, users do not need to be proficient in the field of database optimization to obtain professional advice on query statement performance optimization. Maximize the performance of query statements, improve query efficiency, and save query calculation and computing resources. With the development of database technology, the database market is showing a trend of diversi...
