clarification on backpressure metrics in Apache Flink Dashboard

[Marco Villalobos-2]

given:

[source] -> [operator 1] -> [operator 2] -> [sink].

If within the dashboard, operator 1 shows that it has backpressure, does that mean I need to improve the performance of operator 2 in order to alleviate backpressure upon operator 1?

[Chesnay Schepler]

Yes. Unless operator 2 is also back-pressured of course, then you should
take a look at the sink.
