Problems solved by technology

When the data source fails, the service thread will be blocked. At this time, a large number of user query requests cannot be processed in real time, resulting in service paralysis
[0003] Therefore, the existing above-mentioned data query methods rely too much on the data source, and a failure of the data source will cause a series of problems, resulting in system instability

Abstract

The embodiments of the invention provide a data query method and device. The data query method comprises the steps of: calculating data quality parameters of all data sources in real time through a pre-built data analysis system, wherein the data quality parameters comprise average return time consumption and a data error rate; adjusting the priority weight of all data sources on the basis of calculated data quality parameters, wherein the priority weight is in positive correlation with the data quality parameters; preferentially sending a data query request to a data source with a high priority weight; and receiving structured data including target data fed back by the data sources, and extracting the target data from the structured data on the basis of data source configuration information. Thus, the influence of data source faults on the system is reduced; and the system stability is improved.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a data query method and device. Background technique [0002] For credit reporting companies, their credit reporting business is highly dependent on data sources. Specifically, credit reporting companies obtain query requests from the user side, send the query requests to external data sources, and then receive the data queried by the data sources and Feedback to users. When the data source fails, the service thread will be blocked. At this time, a large number of user query requests cannot be processed in real time, resulting in service paralysis. [0003] Therefore, the above-mentioned existing data query methods rely too much on the data source, and a failure of the data source will cause a series of problems, resulting in system instability. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a data query ...
