Introduction

GreptimeDB is an open-source, 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.

Features

Feature	Description
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.

Troubleshooting:

• Cannot connect to the database? Ensure that ports 4000, 4001, 4002, and 4003 are not blocked by a firewall or used by other services.
• Failed to start? Check the container logs with docker logs greptime for further details.

Build From Source

Prerequisites:

• Rust toolchain (nightly)
• Protobuf compiler (>= 3.15)
• C/C++ building essentials, including gcc/g++/autoconf and glibc library (eg. libc6-dev on Ubuntu and glibc-devel on Fedora)
• Python toolchain (optional): Required only if using some test scripts.

Build and Run:

make
cargo run -- standalone start

Tools & Extensions

• Kubernetes: GreptimeDB Operator
