Summary: FlinkKinesisProducer violates at-least-once guarantees (1.3 branch) Key: FLINK-7931 URL: https://issues.apache.org/jira/browse/FLINK-7931 Project: Flink Issue Type: Bug Components: Kinesis Connector Reporter: Tzu-Li (Gordon) Tai Assignee: Tzu-Li (Gordon) Tai Priority: Blocker Fix For: 1.4.0, 1.3.3 Currently, there is no flushing of KPL outstanding records on checkpoints in the {{FlinkKinesisProducer}}. Likewise to the at-least-once issue on the Flink Kafka producer before, this may lead to data loss if there are asynchronous failing records after a checkpoint which the records was part of was completed. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
