Zhengqi Zhang created FLINK-22438: ------------------------------------- Summary: add numRecordsOut metric for Async IO Key: FLINK-22438 URL: https://issues.apache.org/jira/browse/FLINK-22438 Project: Flink Issue Type: Improvement Components: Runtime / Metrics Affects Versions: 1.12.2 Reporter: Zhengqi Zhang Attachments: QQ截图20210424004201.png
In Flink WebUI,there is no numRecordsOut metric,and the class AsyncWaitOperator did't have this metric in fact.Other operators have this metric, which makes it difficult to monitor Async IO operator and can cause confusion for users. I think we can directly use the wrapping output class CountingOutput to update numRecordsOut metric.CountingOutput is used in super class of AsyncWaitOperator(AbstractStreamOperator). Here is my commit,And I have run a test, it work.
