~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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::

This is just for a single aggregated time series. If your archive policy uses
the 8 default aggregation methods (mean, min, max, sum, std, median, count,
95pct) with the same "one year, one minute aggregations" resolution, the space
used will go up to a maximum of 8 × 4.5 MiB = 36 MiB.

In Gnocchi, the archive policy is expressed in number of points. If your
archive policy defines a policy of 10 points with a granularity of 1 second,
the time serie archive will keep up to 10 seconds, each representing an
aggregation over 1 second. This means the time serie will at maximum retain 10
the time series archive will keep up to 10 seconds, each representing an
aggregation over 1 second. This means the time series will at maximum retain 10
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.
