However, once you have it running it does appear to work. I've seen production setups that ingest a fair amount of data per day and they don't need a lot of maintenance, which is always nice.
On a further note, I attended Grafanacon and saw a few keynotes given by the CEO of InfluxDB and have never been more turned off of using a product by a single person.
Federated prometheus or timescaledb maybe?
