Abstract

The present invention provides a data lineage analysis method, device, equipment, and storage medium. The method includes: a data lineage analysis method, including steps: S1, acquiring the script of the scheduling task; S2, analyzing the script of the scheduling task, and acquiring Database connection information, SQL statements, and the non-loop directed graph of the flow direction between the scheduling task job nodes; S3, traverse each job node, determine the input field set, output field set, and field mapping information inside the job node; S4, based on the The directed acyclic graph and the field mapping information inside the job node are constructed, and the connection between the input field set and the output field set is constructed to generate a data lineage graph. The present invention conducts data lineage analysis based on task scheduling and database embedding points, can process SQL statements using wildcards, and at the same time automatically adapts to changes in the table structure in the database, without manually modifying the SQL statement field part in the ETL script, and dynamically generates a data lineage map .

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a data lineage analysis method, device, equipment and storage medium, in particular to a data lineage analysis method, device, equipment and storage medium based on scheduling task scripts and database buried points. Background technique [0002] Lineage analysis is a technical means for comprehensively tracking the data processing process, so as to find all relevant metadata objects starting from a certain data object and the relationship between these metadata objects. The relationship between metadata objects specifically refers to the data flow input-output relationship representing these metadata objects. [0003] With the development and application of big data technology, there is a demand for data lineage analysis in the field of big data governance. Through the analysis and processing of structured query statements for database operations, the mapping relat...
