- Then we need to create a database 'test' by cli in table model
- ```
- create database test;
- use test;
- ```
- Then we need to create a database 'table'
- ```
- CREATE TABLE mix3 (
- time TIMESTAMP TIME,
- region STRING TAG,
- plant_id STRING TAG,
- device_id STRING TAG,
- model_id STRING ATTRIBUTE,
- maintenance STRING ATTRIBUTE,
- temperature FLOAT FIELD,
- humidity FLOAT FIELD,
- status Boolean FIELD,
- arrival_time TIMESTAMP FIELD
- ) WITH (TTL=31536000000);
