> Currently, if we use disable align keyword, we will get a resultset with 2 * n columns(n is the number of the sensors), like:
> Time, root.sg1.d1.s1, Time, root.sg1.d1.s2, Time, root.sg1.d1.s3
> 1 1 2 2.0 3 "3"
> After some user survey, we decide to change the result format to fixed four columns, like:
> Time, senser_id, value, data_type
> 1 root.sg1.d1.s1 1 INT32
> 2 root.sg1.d1.s2 2.0 FLOAT
> 3 root.sg1.d1.s3. "3" TEXT
