Is Not Contained In¶
Check: is-not-contained-in-check
Purpose: Validates that column values do not belong to a defined set of forbidden values. Use this to block known invalid states, test data, or disallowed categories from entering the pipeline.
This check supports any data type comparable by equality (strings, integers, dates, etc.).
Typical Use Cases¶
- Block test or dummy records from being processed in production datasets.
- Reject entries with invalid country codes or placeholder values.
- Detect rows carrying known-bad status values that should have been filtered upstream.
