When data is versioned according to the definition in the catalog.yml, are there any tools available to quickly compare and contrast changes in the dataset? For instance, let's consider extracting data from a SQL table, with the extracted data being saved periodically on a monthly basis. Is it possible to perform basic data comparisons to identify what has changed? This could save us a significant amount of time before proceeding to the next steps.
