Metadata based

These monitors are derived directly from the data platform’s system metadata, without scanning row-level values. They surface structural signals, such as:

• Last modification time: when the dataset was last updated

• Schema changes: any alterations to the schema

• Total row count: the overall number of records in the dataset

• Total row count change: the delta in row count compared to the previous observation

Because they read only metadata, these monitors are extremely lightweight to compute and ideal for continuous, real-time dashboarding of dataset activity.
