- Cost‑effective storage via compressed logs with label‑based indexing (no full‑text index)
- Seamless integration with existing Prometheus labels for unified metrics‑and‑logs observability
- Native support in Grafana for querying and visualizing logs
- Designed for Kubernetes: automatically scrapes Pod metadata as log stream labels
