Reshaping Steps

Recipe steps that change the number of rows in the dataset have additional impacts on your dataset and its samples. These reshaping steps include the following transforms:

splitrowsSplitrows Transform
flattenFlatten Transform
keepKeep Transform
deleteDelete Transform
pivotPivot Transform
unpivotUnpivot Transform
joinJoin Page
unionUnion Page
lookupLookup Wizard
deduplicateDeduplicate Transform


When one of these transforms is applied and rows are removed from your dataset:

  • Any samples generated before the step was added are invalidated and cannot be used.
  • If you edit steps in your recipe before this added transform, any samples that you generated after the transform step are invalidated and cannot be used.
  • A valid head sample is always available for use.

For more information, see Samples Panel.
