Abstract

The invention provides a method and device for updating a distributed data warehouse. The method includes the steps of dividing service data into new data, changed data and old data according to preset rules, dividing stored data in a service partition of the distributed data warehouse into updated data and non-updated data according to the preset rules, removing the updated data from the service partition, inserting the updated data into preset positions of the service partition, and inserting the changed data into the position of the updated data.

Description

technical field [0001] This application relates to the computer field, and in particular to a method and device for updating a distributed data warehouse. Background technique [0002] With the development of the Internet, more and more data are generated, the data shows explosive growth, the data structure has also begun to diversify, the amount of information contained in the data is increasing, and people are paying more and more attention to data analysis and research. The data warehouse plays a huge role in this context. The data warehouse researches and solves the problem of obtaining information from the database for the work of analyzing and processing the data. Due to the advent of the big data era, data warehouses are slowly turning into distributed architectures to meet the growing computing and storage requirements. Since distributed data generally uses columnar storage and is stored in the form of files, although the storage and calculation of big data are impr...
