Cumulative Sum for Grouping

Calculates the cumulative sum of a given value column, with the group defined by the grouping column.

Note that this component does not perform any sorting of the data and will treat every change of group name as a new group. If your data is not already grouped into contiguous blocks of rows representing each group, you must sort your data prior to using this component.
