Fabian Paul created FLINK-23875: ----------------------------------- Summary: ReducingUpsertSink can loose record during failover Key: FLINK-23875 URL: https://issues.apache.org/jira/browse/FLINK-23875 Project: Flink Issue Type: Bug Components: Connectors / Kafka, Table SQL / API Affects Versions: 1.14.0 Reporter: Fabian Paul
When trying to rework the Table API Kafka connector to make it compatible with the new KafkaSink I noticed that currently the buffer which is used to reduce the update-before and update-after calls is not snapshotted which can result in data loss if the job fails while the buffer is not empty. -- This message was sent by Atlassian Jira (v8.3.4#803005)
