[jira] [Comment Edited] (FLINK-13384) The backpressure monitoring
does not work for StreamSources
[ https://issues.apache.org/jira/browse/FLINK-13384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16891049#comment-16891049 ]

-------------------------------------------------------------------
After further investigation I found out that it does not work only for {{StreamSource}}s. I think it is caused by: [FLINK-12483]. The reason is that the {{BackPressureStatsTrackerImpl}} samples only the main thread. FLINK-12483 introduced a separate thread for executing the sources in the mailbox model. It is similar to other old bug that concerned only Kafka source: [FLINK-3456]
[~pnowojski] [~1u0] Could you verify if this is the case?
