I'm using VictoriaMetrics (VM) to store basic weather data, like temperature and humidity. My initial setup was based on Prometheus however it seemed very hard to set a high data retention value, default was something like 15 days if I recall correctly.

Since I would actually like to store all recorded values permanently, I could partially achieve this with VM which let me set a higher threshold, like 100 years. Still not 'forever' as I would have liked, but I guess me and my flimsy weather data setup will have other things than the retention threshold to worry about in 100 years.

Would be nice to learn the reason why an infinite threshold is not allowed.
