[jira] [Created] (FLINK-19130) Expose backpressure metrics / logs for function dispatcher operator

Tzu-Li (Gordon) Tai created FLINK-19130:
-------------------------------------------

             Summary: Expose backpressure metrics / logs for function dispatcher operator
                 Key: FLINK-19130
                 URL: https://issues.apache.org/jira/browse/FLINK-19130
             Project: Flink
          Issue Type: Task
          Components: Stateful Functions
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai


As of now, there is no visibility on why or how backpressure is applied in Stateful Functions.
This JIRA attemps to add two metrics as an initial effort of providing more visibility:
- Total number of addresses that have asked to be blocked
- Total number of inflight pending async operations
