- bmurphy1976 6y agoThe Grafana blog post mentions Cortex, something I'm not familiar with: https://grafana.com/blog/2020/12/15/announcing-amazon-managed-service-for-grafana/ https://grafana.com/blog/2020/12/15/announcing-amazon-manage...
- bboreham 6y agoIt’s Cortex, though the particular configuration shares a lot of code with Thanos. (I am a Cortex maintainer)
- hagen1778 6y agoIf you know technical details, are there any metrics cardinality limitations?
- bboreham 6y agoThere are soft limits _everywhere_, to stop people shooting themselves in the foot. Those can be raised by admins after checking the user knows what they are doing. I do not know what the practical limits are right now; especially I do not know what size hardware AWS run it on. If you were to search the Cortex Slack you would find people talking about instances with 100 million series, also people talking about work to improve scalability.
- valyala 6y agoThey run Cortex. Cortex architecture looks a bit over-engineered [1] when compared to other backends for Prometheus [2]. This may negatively affect system reliability while increasing operational costs and infrastructure costs. I hope Cortex architecture will be simplified in the future.
