GitHub user JackieTien97 added a comment to the discussion: Support IoTDB as 
Time Series Storage

I wonder how you resolve this problem in InfluxDB, because once you change the 
tag value in InfluxDB, it will also generate a new series.

And actually, this can be easily resolved in our relational model, we have four 
types of columns: Time Column, ID Column(tag set in InfluxDB), Attribute Column 
and MeasurementColumn(field set in InfluxDB). And these changing dimensions can 
be saved in Attribute Column which can updated and belong to the previous 
device(won't create a new device).
