grafana/mimir
Grafana Mimir provides horizontally scalable, highly available, multi-tenant, long-term storage for Prometheus.
Scaling Prometheus to billions of time series with object storage — Grafana Mimir turns Prometheus into a horizontally scalable, multi-tenant system backed by cheap object storage like S3 or GCS. Internal testing shows it handling up to 1 billion active time series, with a parallelized query engine for fast global views across many Prometheus instances. Useful for teams outgrowing single-node Prometheus and needing long-term, highly available metric storage.
