ID Dispensers
ID dispensers generate unique identifiers for each row in a data product. Configure rules to build IDs from extracted field values with a prefix, fallback chains when the primary field is empty, and resolution maps that normalize values before ID generation.
ID rule configuration
| Parameter | Type | Description |
|---|---|---|
| Source field | field | The primary field to derive the ID from. When empty, generates a prefix-less sequential ID. |
| Fallback chain | field[] | Ordered list of alternative fields tried when the source field is empty on a row. |
| Resolution map | map | Key-value lookup that normalizes field values before ID generation (e.g., "ACME Corp" → "ACME"). |
ID rules are persisted before generating IDs. Navigate to a data product detail page and use Apply ID Rules to generate or Regenerate IDs to refresh.
