Distributed data system

Abstract

The embodiment of the invention provides a distributed data system. The distributed data system comprises a management module and a plurality of service modules, wherein the management module is usedfor storing and managing the association relationships between the service modules and searching the target service module which has the association relationship with a source service module currentlyaccording to the stored association relationships after a first data request sent by any one source service module is received; whether or not the target data requested by the source service module is provided by the current associated target service module is judged, when the judgment result is yes, a second data request is sent to the current associated target service module, and the received target data sent by the current associated target service module is fed back to the source service module. When the distributed data system in the embodiment is used, when the association relationshipsbetween one of the service modules and the other service modules are changed, it is only required that the management module automatically updates the stored association relationships, and the maintenance workload of the distributed data system is reduced.

Description

technical field [0001] The invention relates to the technical field of distributed systems, in particular to a distributed data system. Background technique [0002] In the project development process, especially in the development process of large-scale projects, in order to improve development efficiency, it is often necessary to divide a project into multiple business modules, and then several developers complete the development of each business module separately, and finally Integrate the developed business modules into a complete product. [0003] For the distributed data system developed based on the above method, during the operation of the system, the execution of a business module often needs to rely on the execution of one or more other business modules, that is to say, there is an association between the business modules , for example, the execution of business module A requires the execution result of business module B, indicating that business module A and busi...

AI Technical Summary

Problems solved by technology

When the association relationship between one of the business modules and other business modules changes, it is necessary to manually modify the association relationship table in the corresponding business module, resulting in a large maintenance workload for the distributed data system, especially when there are many business modules or the association relationship occurs. The maintenance effort is especially high when the amount of changed data is large or the frequency is high
