Using all data instead of Reservoir Sampling

[emlautarom1]

According to the official docs:

Histograms measure the statistical distribution of a set of values. In high performance applications it is not possible to keep the entire data stream of a histogram in memory. To work around this reservoir sampling algorithms allow us to maintain a small, manageable reservoir which is statistically representative of an entire data stream.

I'm currently using App.Metrics in a batch-processing application that has a fixed lifetime: starts, performs some actions and measures how long they take, and then prints the resulting metrics.

I know in advance that the amount of data can be kept in memory, so I would like to use a sampling strategy that uses all of it. Is it possible to do this out of the box?
