You must implement near‑real‑time ingestion from S3 with schema drift (occasional new columns) while avoiding full listings of the bucket. Badly formed records should land in a quarantine column for triage.

💡 Model Answer
Use Auto Loader with cloud file notifications (S3 event notifications). Auto Loader watches for new files, ingests them incrementally, and automatically handles schema evolution by adding new columns. By configuring a bad records path or a quarantine column, malformed rows are written to a separate location or column for later inspection, keeping the main stream clean.
