What is the best way to store data that does not need to be processed?

Question

Database

I want to use the D3.js plotting library. What is the best way to store the data for the plot - in a database or in a file? At this stage, I do not plan to process them in the data query plan, but I plan to add this data at some time intervals, for example, every minute. I would be grateful for help.

Answer 1

At this stage, I do not plan to process them in terms of data query

This is not very clear.
There is data for plotting. According to this data, graphs will be built with some periodicity = will there be requests?
If you just save some information, then it's easier, of course, purely to a file.

Answer 2

If the author needs to store measurement data (graphics) in append-only mode, then you can look towards InfluxDB.
