> In some occasions, we may need to define *aligned timeseries* such as:
> {code:java}
> create aligned timeseries root.sg.d1.(s1 FLOAT, s2 INT32) 
> with encoding=(RLE, Grollia), compression=SNAPPY
> {code}
> To avoid create timeseries repeatedly when a number of devices / storage groups have same sensors, we intend to introduce the concept of *device template*. For example:
> {code}
> set storage group root.beijing
> create device template temp1(
>   (s1 INT32 with encoding=Gorilla, compression=SNAPPY),
>   (s2 FLOAT with encoding=RLE, compression=SNAPPY)
>  )
> set device template temp1 to root.beijing
> {code}
> So that root.beijing has the template temp1.
