---------------------------------
Summary: SourceOperatorStreamTask increments numRecordsOut twice
Key: FLINK-31752
URL: https://issues.apache.org/jira/browse/FLINK-31752
Project: Flink
Issue Type: Bug
Components: Runtime / Metrics
Affects Versions: 1.17.0
Reporter: Weihua Hu
Attachments: image-2023-04-07-15-51-44-304.png
The counter of numRecordsOut was introduce to ChainingOutput to reduce the
function call stack depth in
https://issues.apache.org/jira/browse/FLINK-30536
But SourceOperatorStreamTask.AsyncDataOutputToOutput increments the counter of
numRecordsOut too. This results in the source operator's numRecordsOut are
doubled.
We should delete the numRecordsOut.inc in
SourceOperatorStreamTask.AsyncDataOutputToOutput
