It would be interesting to compare memory requirements, I chose Influxdb because it had 10 times lower memory usage. The dataset was small (couple of million datapoints)... but stil

That only works when you have one series with a lot of observations. If you have many series with fewer observations (say 50k per series) influxDB uses absurd amounts of memory. I had to switch back to Cassandra because I constantly ran out of memory.

We're working on solving the high cardinality problem. Hopefully soon

How much memory are we talking about? How often did you execute queries on the data?

I'm asking because my first impression of Influxdb involved lots of memory gobbling.
