Would anyone mind sharing what time series DB they use in production, and what for? I'm assuming most are used for metrics in addition to a standard SQL database, but interested to find out if that's accurate. Thanks!
So, there's two use cases for us:
1. We use it to ingest tick-by-tick FX rates
2. We use it to query historical rates e.g. whenever a users opens our homepage we query it directly from TimescaleDB
We've battled tested it pretty hard now & haven't run into any scaling issues - been very much plug & play.

The killer for us is that we allow essentially ad-hoc querying over long time intervals, but require the results to be returned quickly. And the dataset, while not Google proportions, isn't small.
