Abstract

The invention discloses a data query method and device based on a distributed system, and the method comprises the steps: responding to a first data query request, and recording query parameters generated for querying the current distributed system; generating a query voucher according to a parameter combination determined by combining the query parameters; obtaining the query voucher in response to a second data query request; and determining to-be-queried distributed system information and to-be-queried parameters according to the query voucher. Therefore, cross-system data query can be realized in the distributed system, and meanwhile, the accuracy and flexibility of data query under cross-system query are ensured. Moreover, in a multi-system query combination scene, query interface differences of different systems are shielded, and the integrity and consistency of resource query are externally realized.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular, to a data query method and device based on a distributed system. The present application simultaneously relates to a computer storage medium and an electronic device. Background technique [0002] In a distributed system, the same type of resource data is often scattered in multiple system applications for storage. The acquisition of data is limited by the transmission bandwidth limitation of the RPC interface or network request. Therefore, it is necessary to perform paging query on the data. The paging query mainly It is suitable for data centralized storage scenarios. SUMMARY OF THE INVENTION [0003] The present application provides a data query method based on a distributed system to solve the problem that the data query method in the prior art cannot support cross-system scenarios. [0004] The application provides a data query method based on a...
