~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Gnocchi uses a custom file format based on its library *Carbonara*. In Gnocchi,
|

a time serie is a collection of points, where a point is a given measure, or
|

sample, in the lifespan of a time serie. The storage format is compressed using
|

various techniques, therefore the computing of a time serie's size can be

estimated based on its worst case scenario with the following formula::

In Gnocchi, the archive policy is expressed in number of points. If your

seconds of data (sometimes a bit more) between the more recent point and the

oldest point. That does not mean it will be 10 consecutive seconds: there might

be a gap if data is fed irregularly.
