ASF GitHub Bot commented on FLINK-7575: --------------------------------------- GitHub user jameslafa opened a pull request: https://github.com/apache/flink/pull/4647 [FLINK-7575] [WEB-DASHBOARD] Display "Fetching..." instead of 0 when IO metrics are not yet retrieved ## Problem IO metrics is the web-dashboard are retrieved asynchronously. When we display a job's IO metrics for the first time, the API return "0" because values are not yet available. It's misleading. ## Fix There is now a new flag is the API called *metrics-fetched*. If its value is **false**, the dashboard displays "Fetching..." instead of 0.
