             Summary: Make first level flattening optional for input and output
                 Key: FLINK-8185
                 URL: https://issues.apache.org/jira/browse/FLINK-8185
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Timo Walther


When converting a {{DataSet}}/{{DataStream}} into a table. A composite type is automatically flattened to a row of fields, e.g. {{MyPojo<String, String>}} becomes {{Row<String, String>}}. There is no possibility to keep {{Row<MyPojo<String, String>>}}. This would be especially interesting for POJOs that should not be flattened and be converted back to the same type: {{toTable[MyPojo]}}. 

At the moment a user has to specify all fields in order to get the same behavior.
