How can you implement "data drift" detection in Foundry?

• A. Ignore changes and rely on user reports.
• B. Use random sampling to optimize performance.
• C. Compare current data statistics against baselines and raise alerts when distributions shift significantly.
• D. Delete old data.

Answer: (C)

Data drift detection is about identifying when the data you’re using changes from the baseline you expect. In Foundry, you implement it by defining baselines from historical data and continuously comparing current data statistics—such as feature distributions, missingness, and schema—to that baseline. When the distributions shift significantly, you raise alerts so analysts can review and address potential impacts on models, dashboards, or analytics. This approach directly captures when input data feeding your workflows has changed in a way that could affect results. Ignoring changes won’t catch drift, random sampling targets performance rather than drift, and deleting old data erases history and doesn’t provide ongoing detection.
