Detail
to_icebergwith a DataFrame that has new columns in it, the process adds the new columns to the schema, but doesn't upload the values. Therefore, a second call to the function is needed to actually upload the new columns values. This happens because the statementdf = df[catalog_cols]removes the values of new columns in the DataFrame.Relates
