GreptimeDB is a cloud-native database purpose-built for the unified collection and analysis of observability data (metrics, logs, and traces).
Whether you’re operating on the edge, in the cloud, or across hybrid environments, GreptimeDB empowers real-time insights at massive scale — all in one system.
This is free and open source software.
Key Features
- Unified Observability Data – Store metrics, logs, and traces as timestamped, contextual wide events. Query via SQL, PromQL, and streaming.
- High Performance & Cost Effective – Written in Rust, with a distributed query engine, rich indexing, and optimized columnar storage, delivering sub-second responses at PB scale.
- Cloud-Native Architecture – Designed for Kubernetes, with compute/storage separation, native object storage (AWS S3, Azure Blob, etc.) and seamless cross-cloud access.
- Developer-Friendly – Access via SQL/PromQL interfaces, REST API, MySQL/PostgreSQL protocols, and popular ingestion protocols.
- Flexible Deployment – Deploy anywhere: edge (including ARM/Android) or cloud, with unified APIs and efficient data sync.
