>             Project: Flink
>          Issue Type: Improvement
>          Components: Connectors / JDBC
>    Affects Versions: 1.14.4

> If set a primary key to the table, then the connector will use the upsert query to sink data.
> However, the upsert query is not always expected. Because some of the databases don't support upsert well, like Click House. (even though some databases are not supporting officially, I believe many users are extending the dialect by themself)
> So I suggest adding an option like 'sink.append-only' to make the data populated by insert query.
>  
> If we can reach a consensus, I can implement it.
