[jira] [Created] (FLINK-7931) FlinkKinesisProducer violates
at-least-once guarantees (1.3 branch)
Aljoscha Krettek created FLINK-7931:
---------------------------------------
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.
