Stephan Ewen created FLINK-3456: ----------------------------------- Summary: Backpressure Monitoring does not work for Kafka Sources Key: FLINK-3456 URL: https://issues.apache.org/jira/browse/FLINK-3456 Project: Flink Issue Type: Bug Components: Distributed Runtime Affects Versions: 1.0.0 Reporter: Stephan Ewen
For sources that run with Kafka 0.8, the main thread is not the thread that processes elements and pushes them into the network. The Kafka fetcher threads actually emit elements to the SourceContext. Because the backpressure sampler samples the main thread, it does not correctly handle Kafka Sources. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
