DATASET MERGE¶
Merges two or more tabular datasets into a single combined dataset by concatenating rows (union). Use this worker whenever you need to stack a base dataset with one or more additional datasets that share compatible columns.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Source Dataset | dataset1 | dataset | — | The primary (base) source dataset whose rows will form the start of the merged output; must be a tabular dataset compatible with the columns of dataset2. | |
| Dataset 2 | dataset2 | dataset | — | One or more additional tabular datasets to append to dataset1; repeatable — add as many datasets as needed, provided their columns are compatible with the base dataset. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dataset_merge_output_1 | dataset_merge_output_1 | dataset | Single merged tabular dataset containing all rows from dataset1 followed by all rows from the appended dataset(s); column schema reflects the union of all input columns, with NaN fill where columns are absent in a given source. |
