----------------------------------

@[~chenliang613],thx.
For example, now to store a car network data, the data is real-time, the table structure of
the key is the car terminal, each car terminal will have a lot of driving records below, need
to sort the driving records, car terminals do not need to sort , We hope that when the terminal
data is derived, the drive record of the terminal is sorted.
For example (key, col1, col2, col3 ..), the need sorted by a col for the same key row, and
it is best to store the same records of key together. In the load data can do this?

> 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?
