Summary: KafkaDeserializationSchema#isEndOfStream is ill-defined Key: FLINK-16112 URL: https://issues.apache.org/jira/browse/FLINK-16112 Project: Flink Issue Type: Improvement Components: Connectors / Kafka Reporter: Tzu-Li (Gordon) Tai Motivated by this email thread: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/KafkaFetcher-closed-before-end-of-stream-is-received-for-all-partitions-td32827.html In general, the {{isEndOfStream}} method is ill-defined. An possible improvement is to redefine the semantics and method signature, to: {code} boolean isEndOfPartition(T nextElement, String topic, int partition); {code} so that it indicates end of a Kafka partition. With this, the Kafka consumer is able to properly define end-of-subtask to be when all of its assigned partitions have signaled EOF. -- This message was sent by Atlassian Jira (v8.3.4#803005)
