* This is an example, this function needs to be implemented in order to parse the json file into a sql statement
* Note that you need to create a super table and database before writing data
* In this case:
* create database mqttdb;
* create table mqttdb.devices(ts timestamp, value bigint) tags(name binary(32), model binary(32), serial binary(16), param binary(16), unit binary(16));
