I have some random historical meteorological data (multiple time series, ~3 million values, a couple of parameters, nothing big) lying around in a MySQL database which I would love to explore. Grafana looks like a nice tool to at least visualize it.

Which supported data source would you recommend for a quick test ride?

Not openTSDB. That's by far the most difficult to set up. It's also the best in terms of scalability and performance.

Actually, druid.io pretty handily beats it. I've witnessed (another team member) scale opentsdb to an obscene number of writes, but getting data out with more than 3-4 tags for a near-realtime dashboard was pretty much impossible.

Here is a comment on druid I posted recently:

I would go with ElasticSearch.
