Release Spotlight: Mimir 3.0.0
Earlier this week, Grafana Labs announced that Mimir, its horizontally scalable long-term storage for Prometheus, was updated to 3.0.0. Most importantly, it features a new decoupled architecture that involves a Kafka-based ingest storage layer for better scalability and performance.
It also switched to the Mimir Query Engine (MQE) as the default query engine and introduced an experimental support for the Prometheus Remote-Write 2.0 protocol, PromQL duration expressions, and native OTLP delta metric ingestion.
Other noticeable updates in the Cloud Native space:
1. HolmesGPT, an AI agent for cloud troubleshooting (a CNCF Sandbox project), released 0.15. It came with a new Cilium and Hubble toolset, an enhanced New Relic toolset, and improved Gemini support.
2. Backstage, a framework for building developer portals (a CNCF Incubating project), was updated to v1.44.0. Some of its essential changes are a new Dialog component in Backstage UI, support for custom external service auth methods, a new plugin converting Material UI themes to Backstage UI, and easily configured low-level HTTP server options through config.
3. Calico, a container networking and security solution, released v3.31.0. It comes with a streamlined eBPF data plane installation, general availability of nftables data plane, DSCP (Differentiated Services Code Point) marking support, QoS controls for eBPF data plane, fine-grained BGP control with a per-peer local AS number, and numerous other improvements.
4. Vitess, a database clustering system for horizontal scaling of MySQL (a CNCF Graduated project), released v23.0.0. It upgraded the default MySQL version from 8.0.40 to 8.4.6, introduced new metrics (TransactionsProcessed and SkippedRecoveries), and added dynamic control of EmergencyReparentShard-based recoveries to VTOrc.
5. Argo CD (a CNCF Graduated project) released its v3.2.0, which anticipated the deprecation of Argo CD v2.x. New features include health checks for GitOps Promoter resources, new configurable deletion strategies for Progressive Sync, title matching support for the Pull Request Generator in ApplicationSet, server-side diff calculations in Argo CD CLI, and several hydrator improvements.
6. External Secrets Operator, a K8s operator integrating external secret management systems (a CNCF Sandbox project), has reached its v1.0.0, which anticipates its general availability. There are some new features as well — namely, support for generic targets (ConfigMaps, Custom Resources) and a new
