Unpivot column

You can use this step if you need to transform columns into rows. It is the reverse operation of a pivot step.

Unpivoting columns into a unique column means that every unpivoted column header will be used as a label in the output unique column. The columns get unpivoted “around” fixed columns that you can specify. The step creates two new columns: a variable column where you can find the labels corresponding to the unpivoted columns headers, and a value column where you can find the value for every label.

Equivalent to the UNPIVOT clause in SQL.

This step is supported by the following backends:

Mongo 5.0
Mongo 4.2
Mongo 4.0
Mongo 3.6
