For example, a Validator calculates the mean value over a daily window, and then validates if these daily mean values follow an expected seasonal pattern.
List of Validator types and supported metrics
Single Source Validators
Single Source Validators calculate metrics based on one dataset.
Validate the time elapsed since the data was last updated.
Reference Validators
Reference Validators calculate metrics based on multiple fields from two different datasets. The two datasets can either be derived from completely different Sources, or from different windows within the same Source.
These Validators only calculate metrics if there is data in the target dataset. For example, a Categories removed Validator where the reference dataset has 4 categories and the target dataset has 3 categories, yields a result of 1. Conversely, if the target dataset has 0 categories, the Validator does not yield any result. Since this means that the target dataset has no data to calculate metrics on.
