Abstract

The invention discloses an abnormal data checking method and device, and relates to the technical field of computers. The method comprises the steps of acquiring information of stored files of presetdata and information of remote source files of the preset data; verifying the stored files according to the information of the remote source files, and storing information of abnormal data of the stored files obtained by verification, wherein the verification of the stored files includes the verification of the number of the stored files and the size of each file, and the verification whether thestored files include empty files or not; reading the stored information of the abnormal data, and acquiring correction data of the abnormal data from the remote source files according to the information of the abnormal data; and updating the abnormal data in the stored files to the correction data. The data verification logic can be improved; various data abnormal scenes can be satisfied; rapid repair and downloading can be performed when a large amount of data is abnormal; delay is shortened; and coupling with an HBase client is avoided.

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...
