Joe, The specific use cases at the moment both surround QueryDatabaseTable and its Max Value Column tracking.
First, I'd like to be able to set an initial value for a max value column; so essentially an initial state value. The idea would be to support situations where we want to start loading data only from the last 'x' time period. Secondly, if something happened downstream and we need to roll back the clock I want our operations team to be able to stop the processor, change the timestamp to the necessary value, and then start the processor back up as part of their resolution process.

We did not intend for that to be something someone external to the processor could interact with directly. Rather, that is what properties are expected to be used for. So far the couple of requests like this I've seen are where there is a sort of human in the process flow going on - like a workflow manager. Can you describe the details of your use case/ideal user experience a bit further?
