Embodiment Construction

[0040] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is limited to the following description.

[0041] Such as figure 2 As shown, a data traceability method based on a big data model analysis platform includes the following steps:

[0042] S1. Model workflow analysis: Model workflow is a workflow running on the Hadoop platform composed of control flow nodes (for example, start nodes and end nodes) and action nodes, and analyzes the model workflow composed of models on the Hadoop platform Input node, output node and action node, and obtain the unique identifier of each node.

[0043] The step S1 includes the following sub-steps:

[0044] S11. Scanning the model workflow, looking for the first action node of the model workflow, and obtaining the input file path of the first action node as the input file path of the model workflow;

Abstract

The invention discloses a data traceability method and system based on a big data model analysis platform. The method comprises the following steps: S1. Model workflow analysis: analyzing the input nodes, output nodes and Action node, and obtain the unique identifier of each node; S2. Design the traceability information metadata model: describe a traceability file according to each model workflow; S3. Traceability information storage: build an index for the traceability file, and store the index information In the cache database, the index file is stored on HDFS; S4. Data traceability and tracking: determine whether to trace the data generation process, if not, obtain the address of the traceability file by querying the index information. The invention overcomes the problem that the traditional data traceability method is not applicable under the big data platform, builds an index for the traceability file, reduces input / output operations, and improves the query speed.

Description

technical field [0001] The invention relates to the technical field of data traceability, in particular to a data traceability method and system based on a big data model analysis platform. Background technique [0002] The big data model analysis platform is a platform involving model design, development and transaction built on the Hadoop cluster. The system provides a basic model on which users can build their own model through a visual designer, and use this model to analyze the industry data provided by the platform. Since the underlying storage and computing are supported by Hadoop clusters, this platform is a model analysis platform built on top of a big data environment. The design diagram of the model is shown in figure 1 shown. [0003] In recent years, with the development of computers and mobile Internet, all kinds of information have grown explosively. These information can basically be divided into two categories, one is the original input data, and the other...
