> Understanding why a given program behaves in a certain way is often difficult and requires in many cases profiling. The profiling allows to detect hot spots in a program which are worthwhile for further investigation. For non-distributed applications there exists a wide variety of useful tools which achieve exactly that. However, Flink currently lacks the capability to profile distributed jobs.
> Therefore, we would like to set up the infrastructure necessary for distributed profiling. First, this requires a thorough evaluation of existing tools in order to see how they could be used for profiling within Flink. 
> The profiling will most likely comprises the following steps:
> 1. Initiating the system and user code instrumentation
> 2. Collecting the profiling information on the distributed components
> 3. Aggregation of the generated profiling information and a proper visualization
