I was testing out both TimescaleDB/InfluxDB recently, including maybe using with Prometheus/Grafana. I was leaning towards Timescale, but InfluxDB was indeed a lot easier to quickly boot a "batteries included" setup and start working with live data.

I eventually spent a while reading about Timescale 1 vs 2, and testing the pg_prometheus[1] adapter and started thinking through integrating its schema to our other needs then realizing it's "sunsetted" and then reading about the new timescale-prometheus[2] adapter and reading through its ongoing design doc[3] with updated schema that I'm less a fan of.

I finally wound up mostly-settling on Timescale although I've put the Prometheus extension question on hold, just pulling in metrics data and outputting with ChartJS and some basic queries got me a lot closer to done for now. Our use case may be a little odd regardless, but I think a timescale-prometheus extension with a some ability to customize how the data is persisted would be quite useful.

(TimescaleDB engineer) Really curious about finding out more about your reservations about the updated schema. All criticisms welcome.

Thanks, as I say our use case may be too odd to be worth supporting, but effectively we're trying to add a basic metrics (prom/ad-hoc) feature to an existing product (using Postgres) with an existing sort of opinionated "ORM"/toolkit for inserting/querying data.

Because of that and the small scale required, the choice of table-per-metric would be a tough fit and I think a single table with JSONB and maybe some partial indexes is going to work a lot better for us. It would just be nice if we could somehow code in our schema mapping and use the supported extension, but I get it may be too baked-into the implementation.

Anyway, overall we're quite happy with TimescaleDB!

I see, that makes a whole lot of sense. This is an interesting use-case. It actually may be possible to use some of the aggregates provided by the extension even with a different schema.

I found this to be a funny, subtle insult. :-)

"Why is it difficult, because you're self managed?"

I think it's a honest question. Maybe they want to find out if setting up needs a bit of us work or simplifying.

No intention to insult - just trying to get more context :)

I know - I just read it as such and chuckled.
