### Apache Hop version? 2.3.0 ### Java version? OpenJDK 11 ### Operating system Linux ### What happened? If you have a GroupBy transform and you are asking to give back the number of incoming rows, the _Always give back a result row_ flag is always set (even if you try to save it as unset) so that it always tries to give back a result row even if that is not requested. This bug gives a performance issue on complex pipelines because, even if not wanted, the transform is trying to generate as output an empty row and takes a lot of time to generate it because it takes a lot of time discovering the layout of the generated output flow. We tested that this feature was perfectly working up until Hop 1.2.0. ### Issue Priority Priority: 2 ### Issue Component Component: Transforms -- This is an automated message from the Apache Git Service.
