> Each time series is represented by a device id and a measurement name, which
> are two strings. The memory usage may be large when there are too many time
> series.
> One possible improvement is using String.intern(), which is designed for
> reducing memory usage and improve performance.
> A blog about String.intern() is here (in Chinese)
