Grafana Labs announced its shift from contributing to Cortex after five years, launching Grafana Mimir, a new open-source long-term storage for Prometheus. At KubeCon + CloudNativeCon Europe 2021, various team members from Grafana Labs will deliver presentations on topics including Cortex's scalable multi-tenant features, updates from the CNCF SIG Observability, the evolution of Cortex from a vendor-driven project to a community-backed initiative, and an overview of Jaeger and its future with OpenTelemetry. Additionally, discussions will cover the benefits of Cortex's "shuffle sharding" technique for better scalability and isolation and updates on Prometheus' new features and contribution opportunities. The virtual conference aims to unite cloud-native enthusiasts, with sessions accessible through the CNCF Slack workspace.
