Custom technical lineage
You can create a custom technical lineage to include metadata of data sources that are not supported. To do so, you need to create and configure a JSON file that defines the custom technical lineage. You then add the properties of the JSON file to the configuration file.
Example
You want to create a technical lineage that shows relations between tables and columns from system A and system B to system C to system D (A and B -> C -> D). System A, B and D are supported data sources, but system C is a custom application. In this case, you can create a JSON file that contains the metadata of system C. This allows you to create a custom technical lineage that would be otherwise broken.
