Announcing Grafana Mimir, the most scalable open source TSDB in the world

Grafana Mimir is introduced as the world's most scalable open-source time series database, designed to manage over one billion metrics with features like high availability, multi-tenancy, and rapid query performance that surpasses its precursor, Cortex, by up to 40 times. Originating from the Cortex project initiated in 2016 to offer a scalable Prometheus-compatible solution, Mimir incorporates advancements from Grafana Enterprise Metrics and Grafana Cloud, all under the AGPLv3 license to balance open-source contributions with commercial benefits. Mimir simplifies deployment and maintenance, addressing previous technical debts, and can serve as a drop-in replacement for Cortex, facilitating a seamless migration. It supports not only Prometheus metrics but is also set to integrate with other formats like Influx and OpenTelemetry, embodying Grafana Labs' "big tent" philosophy by forming a comprehensive observability stack alongside Loki, Grafana, and Tempo.
