It would be something that is periodically replaying the event stream like a view, but can then be changed into a normal writing processor. Have you thought about using an active standby? It would do the exact same thing as the primary, but the output (external side effects) would be ignored/filtered on the standby. It depends very much on your domain if that is a good or bad idea.
