> Setting storage group and creating time series can be troublesome when using IoTDB in applications.
> Let's look at the typical scenes:
> The devices send messages to Kafka. Each message includes: factoryId, deviceId, timestamp, s1_value, s2_value, s3_value. 
> The consumer of Kafka needs to consume the messages and organize the data into an insert statement: "insert into root.factoryId.deviceId(time, s1, s2, s3) values(timestamp, s1_value, s2_value, s3_value)"
> Before inserting the data into IoTDB, the consumer needs to judge whether the storage group and time series are created before, which is not convenient. Typically, there are 3 ways to do that:
>  # Caching the storage group and timeseries created before in the consumer
>  # Query from IoTDB whether a storage group and timeseries exists
>  # Directly create metadata regardless of whether created before
> Could IoTDB support creating metadata (at least time series) automatically when receiving an insertion?
