Abstract

The invention discloses a method and device for checking abnormal data, and relates to the technical field of computers. The method includes: obtaining the information of the stored file of preset data and the information of the remote source file of the preset data; verifying the stored file according to the information of the remote source file, and saving the verified file Describe the information of the abnormal data of the stored file, wherein, verifying the stored file includes: verifying the number of stored files, the size of each file, and verifying whether the stored file includes an empty file; reading the information of the stored abnormal data , and acquire the correction data of the abnormal data from the remote source file according to the information of the abnormal data; and update the abnormal data in the stored file to the correction data. It can improve the data verification logic to meet various data exception scenarios. When a large number of data exceptions occur, it can quickly repair the download, slow down the delay, and avoid coupling with the HBase client.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for checking abnormal data, electronic equipment, and a computer-readable medium. Background technique [0002] With the rise of big data technology, most businesses need to collect data from different data sources (website crawlers, other business systems, relational data, etc.). In the process of data collection, there will inevitably be various problems, such as data loss, data duplication, etc., so a complete data quality verification solution is required. [0003] Existing data quality verification solutions use Python (an object-oriented interpreted computer programming language) to call shell (computer shell) commands to perform data verification and re-acquisition operations. In the data verification stage, only the downloaded The size of the file, and use the shell command to access the database (HBase) that saves the abnormal data obtained...
