      Description

      Auto grouping can help reduce #tasks in cartesian product but may still result in too many tasks in case of huge input data. It will be useful for user to cap #task, so that cartesian product won't abuse available resource. The primary limiter will still be auto grouping, but this will be a hard limit which cannot be exceeded anyway.
