GitHub user QiangCai opened a pull request:
https://github.com/apache/incubator-carbondata/pull/715
[CARBONDATA-782]support SORT_COLUMNS
The tasks of SORT_COLUMNS:
Support create table with sort_columns property.
e.g. tblproperties('sort_columns' = 'col7,col3')
The table with SORT_COLUMNS property will be sorted by SORT_COLUMNS. The order of columns is decided by SORT_COLUMNS.
Change the encoding rule of SORT_COLUMNS
Firstly, the rule of column encoding will keep consistent with previous.
Secondly, if a column of SORT_COLUMNS is a measure before, now this column will be created as a dimension. And this dimension is a no-dicitonary column(Better to use other direct-dictionary).
Thirdly, the dimension of SORT_COLUMNS have RLE and ROWID page, other dimension have only RLE(not sorted).
The start/end key should be composed of SORT_COLUMNS.
Using SORT_COLUMNS to build start/end key during data loading and select query.

@jackylk thanks for you reply, in my opinion i think that it's better to create a branch-1.1 for preparing for 1.1 release, and keep branch master as development branch.

This PR is actually merged into 12-dev which is branch for CarbonData 1.2 development. Master branch now is preparing for 1.1 release, so no new feature will be merged into master until 1.1 is released.
