It isn't a small footprint, but Druid is the best of breed yet most often underrated tool in this space. Influx gets the press because of the simplicity in setting it up, but epic failed at clustering by trying to invent their own multi-raft magic. If you're not analyzing a lot of data Druid doesn't make sense to setup but if you do, it is simply incredible. I can do analytics on 5+ dimensions with 10 billion datapoints quick enough to make it very responsive in grafana. Their most recent release looks quite interesting as well.
