How to order the data by physical fields in Apache IoTDB?

Can order by in Apache IoTDB order by fields in time series, instead of ordering by time or device? I want to find the utility data distribution of a certain device during a certain period of time, and now I can only query out all the data during this period and then order the utility data by myself. I wonder if there is an easier way for me to know the distribution of data?

If you want the distribution of data in Apache IoTDB, aside of using max and min functions, you can also use Top K to get the corresponding quantile you want. Also, you can try to use aggregate functions to know more, or write a program to get the data fields.
