Hi Enno Thank you for your reply. My problem is that I have no idea how to deal with the issue that I receive only a start message from the device but the values are located in an extra database and that the devices start at different times.
Each device has a step function with a different length. The step function consists of minutes and every minute has a different value. The problem is that I have no idea how to tell the tool to start different step functions at a different times and how to add up the values of every minute in realtime. Is that possible within Storm or is it possible to use a NoSQL database or something like that? Or do I need a tool for predictive analytics like RapidMinder, R, Orange, Weka and so on. Unfortunately I have no idea how to solve this problem as I could not find any examples for such a use case. Most examples for predictive analytics are based on historical data and I think it even is not a real predictive analytics use case as I already know the values for the future. Do you have any examples or an advice how to proceed? Thank you very much in advance.
