OpenObserve Prometheus Mimir
OpenObserve vs Prometheus & Mimir: Metrics Benchmark
We pushed the same ~2.2 billion samples through one OTel Collector into Prometheus, Grafana Mimir, and OpenObserve (Parquet and Vortex) simultaneously, then ran identical PromQL over a frozen 1.09-million-series dataset. OpenObserve answered irate queries ~15x faster, the million-series histogram ~6x faster, and held ingestion to half of Prometheus's memory.
