As we clean the metadata topic when switching from Batch mode to Streaming mode, there is nothing special we need to do.

For the case, that an application gets started in Batch mode and the user wants to terminate the application manually, with the goal to restart with new end-offsets, we need to provide tooling to delete the currently stored end-offsets from the metadata topic. Otherwise, restart would be handled as failure restart because the application did not terminate itself in a clean manner. We can extend the Application Reset tool with an additional flag --delete-stop-offsets that enables the user to delete the metadata topic.
