---------------------------------------
[~jark] thanks . You're right . But i've checked the kafkatablesink. I don't
think an overwrite of 'KafkaTableSink' and 'KafkaTableSourceSinkFactory' is a
perfect way to gain the end-to-end exactly-once semantic when a user develops
an app . It's a too complex for a flink app developer and it makes him focus
too much on the details of flink. I think we'd better expose a semantic
configuration for app users to set when they want exectly-once semantic.
You can have a look at the following issue i opened. How do you think about it?
