> expect:
> 1. split the sql automatically and make it possible to process
> 2. it could be slowly but could not return error or timeout
> 3. tell the user the process of output, like how many sensors, devices, lines
> or points have been processed.
> 4. print the time when the command started and ended.
> 5. print the statistics of processing. e.g. how many output files , how many
> points etc.
