Hi Zoltan, LGTM!

PS1, Line 10: field-id
Could you add that this becomes the default for Iceberg tables as well?

PS1, Line 62:   enum SchemaResolutionStrategy {
            :     POSITION,
            :     ICEBERG_FIELD_ID
            :   };
Do you think this would worth to be generalized with 
TParquetFallbackSchemaResolution? Couldn't find if Iceberg has resolution 
strategies worth switching between.
