I believe if you give the correct fields that are actually contained in
`DataFile` and `DeleteFile`, then it should work, for example:
```
@TypeInfo(DataFile.MbBaseFileTypeInfoFactory.class)
public class DataFile {
... blar blar blar
public static class MbBaseFileTypeInfoFactory extends
TypeInfoFactory<DataFile> {
@Override
public TypeInformation<MbBaseFile> createTypeInfo(Type t,
Map<String, TypeInformation<?>> genericParameters) {
Map<String, TypeInformation<?>> types = new HashMap<>();
types.put("fromProjectionPos", Types.PRIMITIVE_ARRAY(Types.INT));
types.put("fileOrdinal", Types.LONG);
types.put("partitionSpecId", Types.INT);
types.put("content", Types.ENUM(FileContent.class));
types.put("filePath", Types.STRING);
types.put("format", Types.ENUM(FileFormat.class));
types.put("recordCount", Types.LONG);
types.put("fileSizeInBytes", Types.LONG);
types.put("dataSequenceNumber", Types.LONG);
types.put("fileSequenceNumber", Types.LONG);
types.put("columnSizes", Types.MAP(Types.INT, Types.LONG));
types.put("valueCounts", Types.MAP(Types.INT, Types.LONG));
types.put("nullValueCounts", Types.MAP(Types.INT, Types.LONG));
types.put("nanValueCounts", Types.MAP(Types.INT, Types.LONG));
types.put("lowerBounds", Types.MAP(Types.INT,
Types.PRIMITIVE_ARRAY(Types.BYTE)));
types.put("upperBounds", Types.MAP(Types.INT,
Types.PRIMITIVE_ARRAY(Types.BYTE)));
types.put("splitOffsets", Types.PRIMITIVE_ARRAY(Types.LONG));
types.put("equalityIds", Types.PRIMITIVE_ARRAY(Types.INT));
types.put("keyMetadata", Types.PRIMITIVE_ARRAY(Types.BYTE));
return Types.POJO(MbBaseFile.class, types);
}
}
}
```
just to give an example
