An unstructured dataset is an imported dataset that does not contain any initial parsing steps. All parsing steps must be added through recipes that are applied to the dataset. During the import process, you disable the initial steps that are applied to imported datasets. Instead, these steps are added as the first steps of the auto-generated recipe that appears with the dataset in Flow View.

The following menu options are available when you click plus icon next to the unstructured dataset:

  • Add new recipe: Add a recipe for this dataset.
  • Add Join: Join this dataset with another recipe or dataset. If this dataset does not have a recipe for it, a new recipe object is created to store this step.
  • Add Union: Union this dataset with one or more recipes or datasets. If this dataset does not have a recipe for it, a new recipe object is created to store this step.

      NOTE: References to the deleted dataset in other flows remain broken until the dataset is replaced.

Tip: You can also right-click the unstructured dataset to view all the menu options.
