What it shows

  • Ingest raw data into an isolated staging schema before applying validation
  • Great Expectations assertions block corrupted batches and trigger alerts
  • Only certified records are promoted to production dimensional warehouse models

The takeaway

Never promote raw data into production tables without an automated assertion gate at the staging boundary.
