> Nifi source is not stoppable right now. To make it stoppable, is must implement {{StoppableFunction}}. Implementing method {{stop()}} must ensure, that the source stops receiving new messages from Nifi and issues a final checkpoint. Afterwards, {{run()}} must return.
> When implementing this, keep in mind, that the gathered checkpoint might later be used as a savepoint.
