Did you start with Victoria directly? Or move to it from Prometheus? Keen to hear your experiences.
We're currently running Prometheus + Thanos, and high cardinality timeseries are a real issue, which Victoria claims to be good at.

We found Cortex to be extremely over-engineered, extremely hard to tune (because of multiple configuration/argument refactors with incomplete doc cleanups) and found that it would just fall over under load. (Though to be fair, there wasn't much in the way of first-party deployment tooling at the time, so it was a hand-rolled Helm chart and at least 50% of the issues were likely my config).
In comparison, the first-party Victoria Metrics Helm chart worked straight out of the box, the maintainers have fixed multiple small issues within hours of me reporting them and we've thrown an extremely large amount of metrics at it with zero problems.
* It is based on real-world data instead of synthetic data.
* It measures resources usage (RAM, CPU, disk IO, disk space) during production-like load instead of measuring peak performance under the maximum synthetic load.
