THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
In this FLIP I’m proposing to add support for reporting traces/spans (example: 
Traces) and use this mechanism to report checkpointing and recovery traces. I hope in the future traces will also prove useful in other areas of Flink like job submission, job state changes, ... . Moreover as the API to report traces will be added to the MetricGroup , users will be also able to access this API.
