> Currently IoTDB Supports only primitives which are stored in a single measurement. If we would add a "logical" layer on top we could just split each JSON message into its primitives and store it accordingly. If the message is not nested but only key-value pair this is simply a "syntactic sugar".
> Consider the following IoTDB Command:
> {code:sql}
> INSERT INTO root.demo.cars.mycar (time, json) VALUES (NOW(), "{\"speed\": 100, \"color\": \"red\"}")
> {code}
> It uses the word "json" as colum name which indicates that it wants to store a json. Thus IoTDB should store the data from the json and this is equivalent to the normal syntax
> {code:sql}
> INSERT INTO root.demo.cars.mycar (time, speed, color) VALUES (NOW(), 100, "red")
> {code}
