Identifies the column by which the dataset is grouped for purposes of applying the transform.

NOTE: Transforms that use the group parameter can result in non-deterministic re-ordering in the data grid.  However, if you're running your job on the Spark running environment, you should apply the group parameter, or your job may run out of memory and fail. To avoid this issue and to enforce row ordering, use the sort transform. For more information, see Sort Transform.
