I have started using the flux query language with 1.8 when I write new queries, to get the hang of it.
We have VictoriaMetrics on our watch list too.
I have managed to write data to InfluxDB 2.0 at a rate of 100 records per second, which is way above what I would normally require.
Ubuntu 21.04 64 bit on a Pi 3B.
No noticeable CPU or memory problems:
That's good news. Do you have a comparison to previous CPU & memory usage?
I read that you need to enable authentication in 2.0, which adds a small performance cost. In 1.8.x I could get away without this.
I think I will still wait until there is a 64bit-Raspian. I depend heavily on google and on users with more experience. Which means that I need to run the most common OS/tools stack.
This is a new installation, so nothing to compare with. To be fair, they do recommend a Pi 4B with 4GB for 64 bit Ubuntu. I think this is a viable solution for home use, for anyone who wants to start experimenting with InfluxDB 2.0. Bear in mind @Colin's comments above :
