Liang Chen commented on CARBONDATA-745:
---------------------------------------

First,  see if i understood it:
There is a sorted table, and will generate a new table with real-time data.=
 the two tables have one same column(eg: name is key), you want to do join =
by column "key" to merge two tables into one table,  complete sort operatio=
n along with joining operation , is it correct ?

During loading data, can't do like that. For two different table data, you =
must manually do join operation as per your requires.

Regards
Liang

> Now there is a new scene that needs to sort the current data and historic=
al data in real time according to certain rules,and returns the sorted data=
 when querying.
> It's just like hbase put data sorted by rowkey.
> We want to sort the data when we load the data without having to spend ex=
tra time to sort=E3=80=82
> Is it suitable for this scene?
