GreptimeDB Logo

Real-Time & Cloud-Native Observability Database
for metrics, logs, and traces

Delivers sub-second querying at PB scale and exceptional cost efficiency from edge to cloud.

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 youre 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.

3. Docker (Local Quickstart)

docker pull greptime/greptimedb
docker run -p 127.0.0.1:4000-4003:4000-4003 \
  -v "$(pwd)/greptimedb_data:/greptimedb_data" \
  --name greptime --rm \

Dashboard: http://localhost:4000/dashboard Full Install Guide

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.

Getting Started

Build From Source

Prerequisites:

  • Python toolchain (optional): Required only if using some test scripts.

Build and Run:

make
cargo run -- standalone start
