-------------------------------------

             Summary: Display source/sink numRecordsIn/Out & numBytesIn/Out on UI
                 Key: FLINK-33681
                 URL: https://issues.apache.org/jira/browse/FLINK-33681
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Metrics
            Reporter: Zhanghao Chen
         Attachments: image-2023-11-29-13-26-15-176.png

Currently, the numRecordsIn & numBytesIn metrics for sources and the numRecordsOut & numBytesOut metrics for sinks are always 0 on the Flink web dashboard.

[FLINK-11576|https://issues.apache.org/jira/browse/FLINK-11576] brings us these metrics on the opeartor level, but it does not integrate them on the task level. On the other hand, the summay metrics on the job overview page is based on the task level I/O metrics. As a result, even though new connectors supporting FLIP-33 metrics will report operator-level I/O metrics, we still cannot see the metrics on dashboard.

This ticket serves as an umbrella issue to integrate standard source/sink I/O metrics with the corresponding task I/O metrics.
