------------------------------------------
Thank you [~yanghua] to make this clear to me.
I think this issue should be closed as it's not relevant any more
> Let JDBCAppendTableSink be built with java.sql.Connection
> ---------------------------------------------------------
>
> Key: FLINK-10315
> URL: https://issues.apache.org/jira/browse/FLINK-10315
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / JDBC
> Environment: I'm currently using Flink 1.6.0 Java.
> Reporter: François Lacombe
> Assignee: vinoyang
> Priority: Major
>
> Currently, JDBCAppendTableSink is built with methods like setDBUrl,
> setUsername, setPassword... and so on.
> We can't use an existing Java SQL connection to build it.
> It may be great to add a setConnection() method to the builder class as to
> prevent sensitive data like username or password to transit through large
> stacks from config connectors (often in main()) to JDBC sinks.
> To be able to provide only one object is far lighter than 4 or 5 strings
>
> Thanks in advance
