> h3. 【Flink Kafka Connector】
> If the job adds another Kafka topic when the job start from Savepoint, it
> will start to consume from the earlist of that topic, it may cause duplicate
> data sink.
> I found that the configuration is already written in the code
> FlinkKafkaConsumerBase#open(), maybe it can be Configurable.
