I have a data source with 300+ tables. I have a daily profiling job (sample data).

Sometimes, when a table gets changed, and a new field added/existing field dropped, when i open that table in Data Catalog, and in the “Data” tab, it shows that “N” number of metadata changes happened that are marked with a “yellow triangle” symbol (warning/alert).

But, Iam able to see the list of fields that got changes, but iam not able to figure out if it is a new field added or existing field dropped or existing field changed??

How can i get this data?

Hi @Prasad Rani! Table attribute changes can be viewed using Data Observability. This document outlines how to configure Data Observability to track changes within your datasource. For example, I've added a newattribute column and deleted column deletedattribute in a table called jttest1 and the changes are shown in Data Observability (see screenshot). Hope this helps!

Thanks Joyce.


Data Observability, as I understand is a separately licensed product with additional cost, that we may not have purchased.
