From Debugging Towards Live Tuning of Reactive Applications
Directly visualizing the effect of changes to applications improves developers productivity as they gain immediate insights on the resulting application behavior. Yet, immediate feedback requires a representation of the dataflow in the application to correctly propagate and apply the effect of the changes.
Reactive programming is a programming paradigm which directly expresses applications dataflow in a declarative way. Recently, researchers developed dedicated debugging techniques for reactive programming that use the dataflow graph to enable inspections and visualization.
In this paper, we adopt reactive debugging as a basis for live modifications and tuning of reactive applications. To this end we extend the debugger to allow live modifications to the dataflow graph in a structured manner to change the application behavior. We also suggest how developers of reactive applications can use such extension to enable flexible tuning of applications at run time. Our early experience shows that the combination of reactive programming and live programming allows modifications and tuning of applications while ensuring safety and consistency guarantees.
