> 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.
