Not in production just played around with it but looks solid and there are very large production deployments

You might want to check out SiriDB (http://siridb.net)
SiriDB is a 100% open source time series database and should definitely meet your needs.
One of our customers has a 6 node setup consisting of 3 replicated pools which handles a load of 200.000 events per second quite easily.
Currently we have connectors for C, NodeJS, Go and Python as well as a universal http connector.
Adding an elixir connector would be really great so feel free to contribute 
we sure will help where we can!

Is there any interface for reporting updates to continuous queries in real-time? If there is, I’d love to work on an Elixir connector for it.

At the moment we don’t have support for continues queries yet.
We are currently looking how we can implement this, what timeframe are you looking at?

Preferably within the next week or two; they would save computing power by a lot.
Right now I have all time series data aggregated on Postgres, with a simple continuous query executor I did in Elixir keeping track of running amounts for different time windows.

If you’re using Postgres for your standard DB, https://www.pipelinedb.com might be worth investigating. (I have no personal knowledge, I’ve stored this link for later investigation for my own stuff)
