> e.g.
> create table table_desc(key string, value string) clustered by (key) sorted by (key DESC) into 1 BUCKETS;
> create table table_asc(key string, value string) clustered by (key) sorted by (key ASC) into 1 BUCKETS;
> insert overwrite table table_desc select key, value from src;
> insert overwrite table table_asc select key, value from src;
> select * from table_desc;
> ...
> 96 val_96
> 97 val_97
> 97 val_97
> 98 val_98
> 98 val_98
> select * from table_asc;
> ...
