I was about to like InfluxDB but ever since people say it eats memory and your data, I stopped caring.

That hasn't been my experience. I've been running it for ~3 years in our dev, stg, and prod environments. Prod is using 1.5GB of RAM on a 5GB instance. I've never had a data loss issue.
When I first started using it, it was pretty early and had some issues. In fact, I nearly trashed it. I also didn't like the pull vs. push model from Prometheus. They ended up resolving the InfluxDB issues I was having right as I was about to give up on it, and it's been solid since. I use it with Grafana to generate graphs of system use. I set it up before TICK was a thing.
