Joe, So the solution would is to customize QueryDatabaseTable to support reading the initial state Max Value(s) from a property. Then, if I want to change the existing state I stop the processor, clear the state, update my initial Max Value, and start the processor again?

I feel like the QueryDatabaseTable processor should have a property for exactly this. And there is already a clear and well managed model and REST API for operating on those. Does that sound like a fair alternative?
