Split and unfoldΒΆ

This processor splits the values of a column based on a separator and transforms them into several binary columns. Also called ‘dummification’.

For example, with the following dataset:

customer_id events
1 login, product, buy
2 login, product, logout

We get:

customer_id events_login events_product events_buy events_logout
1 1 1 1  
2 1 1   1

The unfolded column is deleted.



The limitations that apply to the “Unfold” processor also apply to the “Split and Unfold” processor.
