Validator overview
For data warehouse sources that provide information as metadata, you can add metadata validators for Freshness or Row Count. Metadata validators do not monitor the actual data in the warehouse. Instead these validators check against the warehouse metadata, allowing you put more validators on your sources without increasing the performance impacts. You can configure the following metadata validators:
For an overview of all validator types, see Validator Types.
Configuration details
When configuring metadata validators, you will only need to select the validator type, define the threshold, and add validator details. Metadata validators can only use global windows and do not support segmentation, filters, or backfill of historical data.Global polling schedule for metadata validators: The polling schedule configured on the source does not apply to metadata validators added to that source. Instead, all metadata validators across sources run on a one hour polling schedule.
