After five years leading the Cortex project, Grafana Labs is no longer contributing to it. In March 2022, we launched Grafana Mimir, an open source, horizontally scalable, highly available, multi-tenant, long-term storage for Prometheus that lets you scale to 1 billion metrics and beyond. Combining the best of what we built in Cortex with features we developed to run Grafana Enterprise Metrics and Grafana Cloud Metrics at massive scale, Grafana Mimir is easy to use and offers high availability, multi-tenancy, durable storage, and blazing fast query performance over long periods of time. We’re excited to share this project with the open source community. To learn more, please read the blog and visit the Grafana Mimir page.
