+A single line of text is used in OpenTSDB line protocol to represent one row of data. OpenTSDB employs single column data model, so one line can only contain a single data column. There can be multiple tags. Each line contains 4 parts as below:
 
 ```
 <metric> <timestamp> <value> <tagk_1>=<tagv_1>[ <tagk_n>=<tagv_n>]
 ```
 
-- `metric` will be used as STable name.
-- `timestamp` is the timestamp of current row of data. The time precision will be determined automatically based on the length of the timestamp. second and millisecond time precision are supported.\
