------------------------------------------

             Summary: Kafka Producer docs should warn if using setLogFailuresOnly, at-least-once is compromised
                 Key: FLINK-5702
                 URL: https://issues.apache.org/jira/browse/FLINK-5702
             Project: Flink
          Issue Type: Improvement
          Components: Documentation, Kafka Connector
            Reporter: Tzu-Li (Gordon) Tai


The documentation for FlinkKafkaProducer does not have any information about the {{setLogFailuresOnly}}. It should emphasize that if users choose to only log failures instead of failing the sink, at-least-once can not be guaranteed .
