Greetings,
In the present version, it is a little trouble some to create a set timeseries that has the same measurements. On the other hand, although we use the conception "device" in the code, it is not properly abstracted. Expected usage: Using IoTDB in a more relational way: CREATE DEVICE TEMPLATE vehicle (speed DOUBLE PLAIN, direction DOUBLE PLAIN, temperature DOUBLE PLAIN, fuel DOUBLE PLAIN) If all datatypes(or encodings) are the same, you can write the equal form: CREATE DEVICE TEMPLATE vehicle MEASUREMENTS (speed, direction, temperature, fuel) DATATYPE DOUBLE ENCODING PLAIN Then you will be able to create time series in an easier way: CREATE DEVICE (vehicle) root.sg1.vehicle1 Which equals: CREATE TIMESERIES root.sg1.vehicle1.speed WITH DATATYPE=DOUBLE,ENCODING=PLAIN CREATE TIMESERIES root.sg1.vehicle1.direction WITH DATATYPE=DOUBLE,ENCODING=PLAIN CREATE TIMESERIES root.sg1.vehicle1.fuel WITH DATATYPE=DOUBLE,ENCODING=PLAIN CREATE TIMESERIES root.sg1.vehicle1.temperature WITH DATATYPE=DOUBLE,ENCODING=PLAIN I hope this will narrow the gap between using IoTDB and traditional relation databases.
