Its core concept is 'dimensional testing' — systematically varying one or more configuration parameters (batch.size, linger.ms, consumer type, partition count, etc.) across a series of identical benchmark runs to isolate their performance impact. Key features include: shareable self-contained result packages (JSON, CSV, interactive charts, Grafana dashboards as HTML), four test modes (run, explore, drain-backlog, correctness), a resources command for pre-benchmark capacity planning, a compare command for cross-run analysis, and Kubernetes as the primary runtime (supporting k3d, minikube, EKS, GKE). The tool is demonstrated with real benchmark examples comparing classic consumer groups vs. Kafka 4.x share groups across varying throughput levels and CPU allocations. It is currently at version 0.x and available on GitHub. ## Full article daily.dev links to this article rather than hosting it.
