Subject how to start tuning to prevent OutOfMemory
Date Wed, 27 Jul 2016 21:43:42 GMT
Hi,

We can see an occasional OOM issue with our Flink jobs. Maybe the
input got more diverse, and the grouping has much more keys, not
really sure about that part.

How do you usually tackle these issues? We are running with
parallelism between 5-30. Would it help if we turn that down?

We do set taskmanager.heap.mb explicitly, but not the advanced config options.

Thanks,
  Istvan
