Automated Feature Store Catalog with Lineage and Usage Metrics

This catalog documents engineered features, their source queries, last refresh times, owning teams, and downstream consumers (models, dashboards). It includes lineage links to source tables and transformation notes and tracks usage metrics to identify stale or high-value features. The workbook supports retirement workflows for unused features and recommends owners for maintenance. Integrate with your feature store APIs to automate refresh timestamps and consumer lists. This improves trust in feature correctness and expedites onboarding of new ML engineers by providing clear provenance and usage data.
