## What it is
GreptimeDB is an open-source (Apache-2.0) observability database written in Rust that stores metrics, logs, and traces in a single columnar engine built on object storage (S3, GCS, Azure Blob). It supports OpenTelemetry, Prometheus Remote Write, PromQL, Loki, Elasticsearch, and InfluxDB ingestion, plus SQL, MySQL/PostgreSQL wire protocols, and Grafana dashboards.

## Use cases
- replace prometheus loki and elasticsearch with one database
- store opentelemetry traces and metrics in a single backend
- cheap long-term metrics storage on s3
- query logs with sql instead of elasticsearch
- self-hosted observability database for kubernetes
- prometheus remote write backend with promql support
- unified metrics logs traces database for ai agent observability

## When to choose
- you want one engine instead of Prometheus + Loki + Elasticsearch/Tempo
- you need petabyte-scale telemetry at low cost via object storage with compute-storage separation
- you want drop-in compatibility with Prometheus, OTLP, MySQL/PostgreSQL, and Grafana
- you run high-cardinality metrics and need inverted, skipping, or fulltext indexes

## When to avoid
- you need a general-purpose OLTP or document database
- your team is deeply invested in a mature single-signal stack like vanilla Prometheus or ELK and migration cost outweighs consolidation benefits
- you require enterprise features like managed SLAs or signed Grafana plugins without a paid tier
