Reshapes

Transpose

Swap two nesting levels in a keyed mapping.

Transpose pivots two declared levels of nested keyed data without model inference.

Worked example

Transpose(
    name="categories-by-attribute",
    input_spaces=("attributes-by-category",),
    output_space="categories-by-attribute",
    levels=(0, 1),
    key="attribute",
)

Parameter	Default	Meaning
`input_spaces`	required	The Space or Spaces read by the reshape.
`name`	required	A stable node name shown in the pipeline and session.
`output_space`	required	The Space receiving the transposed rows.
`levels`	(0, 1)	The two nesting depths to swap.
`key`	id	Field used to identify generated rows.

Output

The same nested information with the selected levels exchanged.

Design guidance

Use Transpose only for nested keyed mappings; ordinary tabular pivots may use Apply.
