[jira] [Commented] (FLINK-15578) Implement exactly-once JDBC sink

    [ https://issues.apache.org/jira/browse/FLINK-15578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17208377#comment-17208377 ] 

Roman Khachatryan commented on FLINK-15578:
-------------------------------------------

Hello [~klden],

I think you can extend [GenericWriteAheadSink|https://ci.apache.org/projects/flink/flink-docs-release-1.11/api/java/index.html?org/apache/flink/streaming/runtime/operators/GenericWriteAheadSink.html]. It's currently used by Cassandra sinks.

Probably [~chesnay] knows more about it.
