# Safe Publish Pattern Flow

> Prepare new data in a staging table, validate it, and publish only after the checks pass. This flow keeps failed results away from the target and includes monitoring after release.

## Reading the sketch

### Build the new data

Run the transformation and prepare the new output.

### Write to staging

Keep the new result in a temporary or staging table instead of writing straight to the target.

### Validate before publishing

Check row counts, uniqueness, nulls, and reconciliation of the key metrics.

### Stop if validation fails

Halt the release and investigate the failed checks before replacing the target.

### Publish the validated result

Use an atomic swap or promotion where the target system supports it. The trusted table should change only when the new data is ready.

### Monitor after release

Check downstream dashboards, confirm freshness, and watch for anomalies after publishing.

## Takeaway

Keep the current target available while preparing and validating its replacement. Failed checks should stop the release; successful checks still need follow-up monitoring.
