Hello Guys,
We are exploring talend's functionalities while waiting for the licence to come. I understand that Talend builds lineage as part of it's Metadata harvesting. I would like to understand the following.
- How it builds the lineage? Is there any prerequisites for that to show the linked arrows? for example. Is primarykey, foreign key relationship required?
- If we need to customize the lineage is it possible? for example, is it possible to mention a lineage which talend doesn't know?
- For example, some one pushes json/excel files to our data warehouse. Talend job takes the files process further till final zone. In lineage flow, is it possible to mention the source system as well?
Please highlight if there are any articles already to explore this. Thank you.
Regards
Ari
