[jira] [Commented] (FLINK-15221) supporting Exactly-once for kafka
table APi
[ https://issues.apache.org/jira/browse/FLINK-15221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16995310#comment-16995310 ]
Jark Wu commented on FLINK-15221:
---------------------------------
Hi [~chaiyq], I didn't mean to let users overwrite {{KafkaTableSink}}. What I suggested is make the exactly once semantic configurable in {{KafkaTableSink}} and {{KafkaTableSourceSinkFactory}}. Users can just set something like {{'connector.semantic='exactly-once'}} in connector properties.
Regarding to FLINK-14719, I left my opinion there.
