Mimir [1] is what we use where I work. We are very happy with it, and we have very long retention. Previously, our Prometheus setup was extremely slow if you went past today, but Mimir partitions the data to make it extremely fast to query even long time periods. We also used Thanos for a while, but Mimir apparently worked better.

I have done mimir deployments. I am generally very happy with mimir. It's very cost efficient. It does require someone to know enough to admin it though.

I didn't pick thanos because I really like the horizonal scaled blob store architecture the Grafana crew put together.

Yeah. Would be interested to see how VictoriaMetrics compares to Mimir, not just Prometheus.

To be fair many projects in Prometheus "long term store" space come and gone - Thanos, Cortex, M3

Here you go https://victoriametrics.com/blog/mimir-benchmark/ It is from Sep 2022, it would be great to get newer results.

Thanos is well alive and kicking, actually used in some of the biggest infrastructure setups in the world such as Shopify and Cloudflare.

Hi! None of these are "gone" in any way, and are actually used in various different enterprises at global scale.

Can you elaborate a bit more on the come and gone part?

They're out of tech posters' zeitgeist but AFAIK they are each still maintained and fulfilling people's needs. Just not as much commentary or front-of-mind-share.
