at many customers we are faced with time series based data. This either comes from a standard database or a HBase / OpenTSDB based infrastructure. All data is near real time and is used to maintain overview of what's currently going on.
Within the agile data science projects, the RapidMiner WebApps present a very efficient way to built mockups for presenting data. As a feedback channel is often needed, I know several projects that are sticking to this way to present data instead of involve another layer of BI Tools.
All that is missing is a nice auto update of the contained data. I wrote a Java Script that implements a regular rerendering of RapidMiners Component with a data update, but this resets zoom and selection every time and flashes the screen. Highcharts are capable of live updates and I wonder, if RapidMiner could implement a simple delta update mechanism. It would just need to reexecute a particular update process with a given frequency and push the delta into the chart, rather than re-rendering the component.
With that in place, I really see RapidMiner Server being used not only for background computation...
