DefinedFieldMappinginterface provides a mapping for the fields of the table schema (
TableSource.getTableSchema()to fields of the physical produced data type
If the fields cannot or should not be implicitly mapped by name, an explicit mapping can be provided by implementing this interface.
If a mapping is provided, all fields must be explicitly mapped.

The mapping is done based on field names, e.g., a mapping "name" -> "f1" maps the schema
field "name" to the field "f1" of the produced data type, for example in this case the second

The returned mapping must map all fields (except proctime and rowtime fields) to the
