Iceberg lists the following properties:
We should also use these properties if possible, e.g. write.format.default, write.<fileformat>.compression-codec
Currently Impala use the table property 'iceberg.file_format' to determine the data file format for reads/writes. In the future, read operations should automatically detect the file formats (
IMPALA-10610), but for writes we should use 'write.format.default'.
