----------------------------------
Assignee: (was: Robert Metzger)
> GSoC project: Distributed profiling
> -----------------------------------
>
> Key: FLINK-1541
> URL: https://issues.apache.org/jira/browse/FLINK-1541
> Project: Flink
> Issue Type: New Feature
> Reporter: Till Rohrmann
> Priority: Minor
> Labels: distributed, gsoc2015, java, scala
>
> 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
