I think for all table property that documented in https://github.com/apache/carbondata/blob/master/docs/ddl-of-carbondata.md <https://github.com/apache/carbondata/blob/master/docs/ddl-of-carbondata.md>, we should write their values in the schema file. Because the default value for these properties may change, if they are changes, user will not know what is the table property that was used when writing the file.
