Abstract

One or more embodiments of the invention provide a data warehouse data updating method and device, an electronic device and a storage medium, and the method comprises the steps: storing target data into a temporary table of a data warehouse, and determining the feature information of the target data; converting the target data into a data extraction file in a specific data exchange format according to the feature information; and calling a data warehouse tool through an agent script to perform data extraction on the data extraction file, and updating the data extraction file from the temporarytable to a formal table of a data warehouse. One or more embodiments of the present specification convert target data into a data extraction file in a specific data exchange format based on feature information of the target data, and then call a data warehouse tool through an agent script to perform data extraction on the data extraction file to update data of a data warehouse. Therefore, incremental updating of the stock data of the data warehouse can be realized, and the data updating timeliness is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of data storage, and in particular to a method, device, electronic device, and storage medium for updating data in a data warehouse. Background technique [0002] Hive is a data warehouse built on top of Hadoop. Using Hive for data storage involves a data update problem. Currently, Hive supports only two operations of overwriting and appending data tables. The coverage described here is not the data coverage of a certain record, but the full coverage of the entire table data. Appending does not mean updating part of the original data or adding changes, but adding the data as a whole to the existing data set. [0003] Hive does not support data update and deletion operations, and can only add content, and uses the full coverage method to update data. When faced with a huge amount of data, such as a data volume of more than 100 million, it will consume a lot of computing resourc...
