One thing that I often miss when reading about this stuff is benchmarks. So it's faster than Prometheus? Prove it. So it's faster than Postgres, or TimescaleDB? Prove it.

It should be trivial, and the fact that it's not there and what you find instead is terms like "Uber-scale" is slightly worrying.

I'm not trying to take anything away from the achievements made here by the guys at Uber, but anyone seriously considering using this in production would probably need a better contrastive comparison between alternatives.
