(Promscale Team Lead Here) Promscale, which connects Prometheus to TimescaleDB also handles high-cardinality well and allows you to use both PromQL and SQL for data analysis. I'd humbly suggest taking a look. Plus our PromQL implementation is 100% standards compliant.

It would be great conducting a benchmark between Promscale and VictoriaMetrics similar to this one - https://valyala.medium.com/prometheus-vs-victoriametrics-ben... . It differs from TSBS in the following aspects:

* 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.

I would love to have some kind of integration between Victoria Metrics and Promscale, using VM for ingest from things like InfluxDB and Promscale for SQL queries on stable data.

This should be already possible - just collect Influx line protocol data with vmagent [1] and write it to Promscale.
