Compare

The Compare feature allows comparing a set of data objects against a base set of data objects to identify changes and data drift. As an example, you may want to compare how last week's data compares with the last three months' data and see if the data is similar or diverging. The Compare option is only available for Explore jobs and for the 'image' dataset type. All the data of old datasets are displayed with round dots, and the data of new datasets are displayed with plus dots.

• A compare job can be specified with a base job on the same dataset, and the base job must be of Explore type.
