Review comment:
yes, for spark all string is varchar itself.
But for carbon if we mention long_string_columns in table properties we change data type from carbonType.string --> carbonType.varchar
for dataframe I think options("long_string_columns"="c1,c2") is not yet supported. So, current changes are ok
