Martijn Visser commented on FLINK-29711:
----------------------------------------
Which Kafka sink are you using, FlinkKafkaProducer or KafkaSink?
Are you using Exactly Once or a different guarantee?
I know that Azure Eventhub can emulate Kafka, but we've also seen that these
emulators can't exactly mirror everything that Kafka is doing (we've seen the
same with RedPanda). My suspicion would be that there's something at the Azure
Eventhub side of things that doesn't work exactly the same as in Kafka.
