Cumulative Count for Grouping

Calculates the cumulative count of a given rows grouped by a given 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.

This is based on my Cumulative Sum for Grouping component but instead of aggregating a "value" column, it returns a ranked count of rows in a group
