Energy Monitor & Recorder - Keep Days vs. Year-Button

The Energy Monitor has the buttons “day, week, year”.

I wonder if the “year” feature works without changing the configuration of the recorder. I read that the default “keep” period of the recorder is 10 days. I guess changing this to 365 would lead to a large database quickly.

What is the concept and recommended way of configuration here?

Comming from FHEM i liked the default year view. Setting up influxx and graphana made my raspberry3 installation instable so i reverted it.
