> Now we just support append JDBC sink, this is very limited. Consider a simple
> wordCount, we need insert/update the sink with primary keys.
> So we need to support upsert JDBC sink.
> 1.Introduce a AbstractJdbcOutputFormat to extract some common method from
> JDBCOutputFormat. Introduce a UpsertJDBCOutputFormat which extends
> AbstractJdbcOutputFormat.
> 2.Introduce UpsertJdbcTableSink.
