      Description

      When the data is loaded with SORT_SCOPE as NO_SORT, and done compaction upon, the data still remains unsorted. This does not affect much in query. The major purpose of compaction, is better pack the data and improve query performance.

       

      Now, the expected behaviour of compaction is sort to the data, so that after compaction, query performance becomes better. The columns to sort upon are provided by SORT_COLUMNS.
