The invention relates to the field of data warehouses, in particular to a decoupling elastic data warehouse architecture. The architecture comprises a data warehouse front end which is used for usinga PostgreSQL as the basis of the data warehouse front end, processing incoming and outgoing data, providing a control and query user interface and managing bottom layer storage; a data warehouse backend which is used for extensible and elastic resource management and single or concurrent query; and a separating the data warehouse middleware which is used for coordinating messaging and data transfer between data warehouse front end and data warehouse back end using Dex. The data management function and the data calculation function are separated to achieve independent expandability, and the elastic data warehouse system structure of the cloud is explored. And the front end of the data warehouse receives the data, manages and stores the data and provides high availability. And the data warehouse rear end is used for data analysis query. Through separated data management and data calculation, elasticity can be obtained in a single data warehouse.
Description
technical field [0001] The invention relates to the field of data warehouses, in particular to a decoupled elastic data warehouse architecture. Background technique [0002] With the growing popularity of the cloud for providing shared and managed IT infrastructure, companies today are eager to move their data platform assets to the cloud to reduce equipment, utility and maintenance expenditures. Moving data warehouses to the cloud is a cost-effective data management trend considered by companies today. To fully realize economic goals, a cloud data warehouse system should be able to adjust its resource configuration to adapt to changing workload demands. However, traditional data warehouse architectures are not flexible enough and do not allow on-demand resource control, which severely limits the cloud provider and user's ability to optimize the total cost and maintain the desired quality of service. [0003] Data warehouses have been around for decades, and their primary ...
