[jira] [Commented] (FLINK-15579) Support UpsertStreamTableSink on
Blink batch mode
[ https://issues.apache.org/jira/browse/FLINK-15579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17015665#comment-17015665 ]
Shu Li Zheng commented on FLINK-15579:
--------------------------------------
[~jark] Hi jark, I'm wondering why BatchExecSink do not support UpsertStreamTableSink now, Could you give me any suggestion? I want to modify BatchExecSink.translateToPlanInternal() and JDBCTableSourceSinkFactory.createStreamTableSink() related code to support UpsertStreamTableSink.
