Description

Metadata-based space-time big data REST micro-service data interaction method and system
Technical Field
The invention relates to the technical field of industrial Internet, in particular to a space-time big data REST micro-service data interaction method and system based on metadata.
Background
In the industrial internet of the Baowu group, each iron and steel plant is deployed with an industrial internet, and each industrial internet is accessed by using a space-time big data REST micro-service architecture. For example, the space-time large data REST service of the internet system of the steel industry in the city of jaw can be accessed only in the steel of jaw, the space-time large data REST service of the internet system of the steel industry in the Zhanjiang can be accessed only in the steel of Zhanjiang, but in practical application, the need for accessing the space-time large data REST service across the industrial internet system exists.
In general, REST services use JSON data format to perform data interaction, and the JSON data returned by REST services is a Key-Value Key pair without metadata information. When using the space-time big data REST service, a developer usually checks the REST service interface document and then calls the space-time big data REST service according to the parameter description and the return value description described by the interface document. This is problematic for the calling end of the spatiotemporal big data REST micro service because it is not possible for the calling end of the spatiotemporal big data REST micro service to know which data are spatial data, and more not possible to know whether these spatial data are points, lines, or planes, among the data returned by the spatiotemporal big data REST service.
Through retrieval, patent document CN111752965A discloses a real-time database data interaction method and system based on micro-service, by embedding an SQL operation request into a REST request message body, adopting a service gateway technology to realize the reception of a REST access request and the analysis of an http message header, and balancing the request load into an access request execution micro-service instance, the access request execution micro-service instance analyzes a micro-service REST request message, extracts the content of the SQL request, invokes a real-time library SQL interface to execute and returns an execution result. The prior art solves the problem of data interaction of a real-time database, but cannot solve the problem of data interaction of space-time big data.
Patent document CN110096653a discloses a method for constructing a space-time information service architecture. The method comprises the following steps: acquiring target space-time data corresponding to a space-time information service interface; determining interface types corresponding to the space-time information service interfaces according to the target space-time data; searching RESTful styles corresponding to the space-time information service interfaces and configuration requirements corresponding to the RESTful styles according to interface categories; according to RESTful style and configuration requirements, modifying the time information service interface to obtain a time information service interface specification conforming to the REST architecture; and constructing a space-time information service architecture according to the space-time information service interface specification. The technical problems that the heterogeneous platform cannot realize resource service sharing and data fusion are solved, and the problem of data interaction of space-time big data cannot be solved.
Therefore, there is an urgent need to develop a data interaction method and system for accessing space-time big data REST service across industrial internet systems.
