I had held off trying the Influxdb option- I thought the Raspberry has enough to do without being a database server as well....
But by the sound of it, it does not use too much processor/memory ?
Are you using the SD card or an external USB drive for the database & how much space does it take up ?
I'm guessing it would be possible to write a query to delete old data- say over 30 days old- if disk space is an issue ?

Watching htop it seems to have a blip of activity every little while but it all seems to work OK. Disk space no doubt would add up if recording lots of data every second , you can set a retention time so if will only keep data for a day or month or whatever you want.
