GET MAP STRING FOR A SET OF COLUMNS¶
Generates a map-string representation for a specified set of columns in a dataset. Use this worker when you need to produce a column-keyed mapping string (e.g., for downstream joins, renaming, or lookup operations) from an existing dataset.
When to use¶
Classification: process.
Tagged: column_mapping, dataset_transform, map_string, transformations.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset | dataset | dataset | — | Input dataset whose columns will be mapped; accepts any tabular dataset object — leave unconnected only if columns are supplied via another upstream path. | |
| Columns | cols | scalar | — | Comma-separated list of column names (quoted strings) from the input dataset for which the map string should be generated; supports multi-select from the dataset’s available columns. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Mapped String | dataset_get_map_string | dataset | Dataset containing the generated map string keyed by the selected columns, ready for use in downstream mapping or lookup workers. |
