I think we can just rephrase the proposal. We want to make the `sort_columns` by default is empty, that is to say if the user does not explicitly specify the sort_columns, the corresponding property will be 'sort_columns'=''. And when the sort_columns is empty, carbondata will use no_sort for it -- This strategy is already there.
So if my understanding is correct, please use the above statements to make that PR more clear and understandable. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
