Apache Superset

For Apache Superset, migrate a dashboard that people already use to make decisions. Preserve its underlying dataset definitions, filters, calculations, row-level access rules, and refresh schedule. Compare the numbers at several dates and under users with different permissions.

Watch query time and database load when multiple viewers open it together. Check whether the candidate explains failed queries and lets an analyst trace a metric back to SQL. Export or document enough configuration for a rollback. A prettier chart is not a replacement if a familiar KPI quietly changes meaning or exposes restricted rows.
