alpinegizmo opened a new pull request #4: [FLINK-14160] Add --backpressure option to the ops playground URL: https://github.com/apache/flink-playgrounds/pull/4 When enabled, this option inserts an operator into the ClickEventCount job that causes severe backpressure every other minute. This can be easily observed in the web UI and metrics. And the speed with which this backpressure becomes noticeable can be changed by altering the amount of buffering used by the network stack. This option is off by default, leaving the application's current behavior unaffected.
