Hi Ravi
Good thinking.
Because the inverted index columns by default are the same as sort_column
columns, from the user perspective, he only need to set no_inverted_index
columns in sort_column columns, so i proposed to display only the
no_inverted_index columns info which be set by user.
Anyway, in "data management on carbondata" need to update the info: inverted
index columns by default be enabled along with sort_columns....
Regards
Liang
