## Introduction
**GreptimeDB** is an open-source observability database that handles metrics, logs, and traces in one engine. Use it as the single OpenTelemetry backend — replacing Prometheus, Loki, and Elasticsearch with one database built on object storage. Query with SQL and PromQL, scale without pain, cut costs up to 50x.
**GreptimeDB** is an open-source observability database built for [Observability 2.0](https://docs.greptime.com/user-guide/concepts/observability-2/) — treating metrics, logs, and traces as one unified data model (wide events) instead of three separate pillars.

* Replacing Prometheus + Loki + Elasticsearch with one database
* Scaling past Prometheus — high cardinality, long-term storage, no Thanos/Mimir overhead
* Cutting observability costs with object storage (up to 50x savings on traces, 30% on logs)
* AI/LLM observability — store and analyze high-volume conversation data, agent traces, and token metrics via [OpenTelemetry GenAI conventions](https://opentelemetry.io/docs/specs/semconv/gen-ai/)
* Edge-to-cloud observability with unified APIs on resource-constrained devices

> **Why Observability 2.0?** The three-pillar model (separate databases for metrics, logs, traces) creates data silos and operational complexity. GreptimeDB treats all observability data as timestamped wide events in a single columnar engine — enabling cross-signal SQL JOINs, eliminating redundant infrastructure, and naturally supporting emerging workloads like AI agent observability.
