How can I stop the event from completing without throwing an exception?

For as far as I know the only way to make a event fail is by throwing an exception.
Because of this the transaction will quit and the completion_date is not filled, so it will retry again later.

The downside of this, is that the elastic logging is polluted with these error messages.
It would be nice if you can call a method that ends the transaction without having to use an exception.
