[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=17006781#comment-17006781 ] 

Jark Wu commented on FLINK-15221:
---------------------------------

Hi [~twalthr], what do you think about this new property? 

I was just thinking that the semantic is only applied to the sink, the source always work in exactly once mode, so maybe we should call it {{connector.sink-semantic='exactly-once' }} ?

> The Table Api doesn't support End to End Exactly once sematic like datastream Api.  Does Flink have a plan for this?
