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 operation 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.

> Priority: Minor

> Does carbondata apply to scenes that need to sort historical and current data?
> Now there is a new scene that needs to sort the current data and historical 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 extra time to sort。
> Is it suitable for this scene?
