Design And Implementation Of Real-time Data Warehouse For E-commerce Platform Based On Flink Framework

With the development of the Internet,online shopping has been integrated into people's daily life.Compared with the traditional shopping mode,the scale of online shopping has gradually expanded,and the diversified information display of ecommerce platforms has also greatly affected consumers' willingness to spend..If the e-commerce platform can grasp the consumer psychology and consumption behavior of consumers in a timely manner,and adjust the platform information,it will increase consumers' willingness to buy.Real-time data warehouse is a data warehouse service that can aggregate and process platform data in real time.Therefore,building a realtime data warehouse for the e-commerce platform can enhance the positive interaction with consumers,so as to predict the consumption trend of the e-commerce industry,and provide practical data support for the development and decision-making of the ecommerce platform.This paper intends to realize the core business functions of the e-commerce platform,build a real-time data warehouse for the e-commerce platform based on the Flink stream data processing framework,realize the real-time data collection and realtime processing through the data layered design,and conduct the theme index statistics on the calculation results,and finally realize the Visual display on the large screen.In the process of technical implementation;on the one hand,the template method design pattern will be used to transform the structure of the Flink execution operator to make it compatible with multi-dimensional associations and realize dynamic association of data streams;On the other hand,use configuration separation design and data serialization to reconstruct and transform,so that the program flow can meet the multi-layer distribution,and realize the dynamic distribution of business data.Through the technical optimization of these two aspects,it makes up for the lack of flexibility in Flink program execution.The overall content of this article will provide a set of feasible data processing and visual display solutions for the e-commerce platform with the help of the core business scenarios and data structure of the e-commerce platform,and from the perspective of the bottom-level design and implementation,it will show the real-time data warehouse and visualized large screen.The technical details of the construction,through the display of such details,indirectly enhance the technical credibility of Flink's real-time data warehouse.
