The sandbox lets you test ingestion safely. You upload a file, Solya parses and validates it without touching production data, and you review the findings before deciding to promote.

​
Two steps

1

Ingest (validate)

Upload a file. A sandbox ingest run parses it, matches an ingestion spec (or one you force), writes to temporary tables, and produces findings.
2

Promote (publish)

If the findings look good, a sandbox promote run copies the validated data into the silver layer for production use.

​
Findings

Each finding has a severity — error, warning, or info — and a stage where it arose (detect, parse, map, loader, strict scan, quarantine). Common finding codes include coercion loss, extra fields, shape drift, loader exception, row validation, parse error, and “no spec matched”. The run keeps the top findings and full logs.

​
Run statuses

Both ingest and promote runs move through PENDING → RUNNING → SUCCESS / FAILED.
A promote run can finish as SUCCESS but aborted — it ran cleanly yet declined to copy because the ingest had errors and you didn’t allow promotion with errors. That’s a safe refusal, not a failure. You can re-run allowing errors if you intend to proceed.
