Introduction

GreptimeDB is an open-source unified time-series database for Metrics, Logs, and Events (also Traces in plan). You can gain real-time insights from Edge to Cloud at any scale.

Why GreptimeDB

Our core developers have been building time-series data platforms for years. Based on our best-practices, GreptimeDB is born to give you:

• Unified all kinds of time series

  GreptimeDB treats all time series as contextual events with timestamp, and thus unifies the processing of metrics, logs, and events. It supports analyzing metrics, logs, and events with SQL and PromQL, and doing streaming with continuous aggregation.

• Cloud-Edge collaboration

  GreptimeDB can be deployed on ARM architecture-compatible Android/Linux systems as well as cloud environments from various vendors. Both sides run the same software, providing identical APIs and control planes, so your application can run at the edge or on the cloud without modification, and data synchronization also becomes extremely easy and efficient.

• Cloud-native distributed database

  By leveraging object storage (S3 and others), separating compute and storage, scaling stateless compute nodes arbitrarily, GreptimeDB implements seamless scalability. It also supports cross-cloud deployment with a built-in unified data access layer over different object storages.

• Performance and Cost-effective

  Flexible indexing capabilities and distributed, parallel-processing query engine, tackling high cardinality issues down. Optimized columnar layout for handling time-series data; compacted, compressed, and stored on various storage backends, particularly cloud object storage with 50x cost efficiency.

• Compatible with InfluxDB, Prometheus and more protocols

  Widely adopted database protocols and APIs, including MySQL, PostgreSQL, and Prometheus Remote Storage, etc. Read more.
