Hi, Depending how you configured your FlinkKafkaSource, but you can make the source to commit consumed offsets back to Kafka. So one way to examine them, would be to check those offsets in Kafka (I don't know how, but I'm pretty sure there is a way to do it).
Secondly, if you want to examine Flink's checkpoint state you can use State Processor API to do that [1]. As far as I know you could hook up your checkpointed data to Table API/SQL and use SQL to query/analyse the state.
