Hi, Flink has a deadlock case and can be caused by the combination of Flink's backpressure mechanism with iterations (more likely when there is heavy feedback load). There is a proposal(FLIP-15) to resolve this issue, but it seems to be abondoned: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=66853132 I propose to add `ThrottledMapper` into `flink-examples` directory of Flink repo, to serve as a walkaround before the deadlock issue gets resolved: https://gist.github.com/nanmu42/53fe23c3f15c777291108a7f4df62b9a I am considering to add in into https://github.com/apache/flink/tree/master/flink-examples/flink-examples-streaming/src/main/java/org/apache/flink/streaming/examples/utils Thanks for your attention. related issues: * https://mail-archives.apache.org/mod_mbox/flink-user/201704.mbox/%3c5486a7fd-41c3-4131-5100-272825088...@gaborhermann.com%3E * https://issues.apache.org/jira/browse/FLINK-2497?jql=project%20%3D%20FLINK%20AND%20resolution%20%3D%20Unresolved%20AND%20text%20~%20%22deadlock%20iteration%22%20ORDER%20BY%20priority%20DESC%2C%20updated%20DESC -- This message was sent by Atlassian Jira (v8.3.4#803005)
