A massively parallel PostgreSQL-based data warehouse from the original Greenplum developers, built for large-scale analytics and AI workloads.
Created by the original developers of Greenplum Database, Apache Cloudberry is a mature massively parallel processing database that evolved from the open source version of Pivotal Greenplum. It carries a newer PostgreSQL kernel and more advanced enterprise capabilities than the code it grew from, and it works both as a data warehouse and as an engine for large-scale analytics and AI or machine learning workloads.
The project is undergoing incubation at the Apache Software Foundation, sponsored by the Apache Incubator. Incubation is required of every newly accepted project until a review finds that its infrastructure, communications, and decision making have stabilized in a manner consistent with other successful ASF projects. That status says nothing about the completeness or stability of the code itself.
Getting started and taking part are both documented in the repository.
- Build from source: guides cover RHEL and Rocky Linux, Ubuntu, and macOS.
- Docker sandbox: a sandbox in the repository gives a first look at the features without a full deployment.
- Ecosystem repositories: separate projects hold the website and documentation, the backup utility, the Go libraries, and the Platform Extension Framework.
- Community channels: Slack for real-time chat, GitHub Discussions for questions and feature ideas, and a published events calendar.
- Contribution paths: code, proposals, and documentation each have their own guide, plus an AI guideline for agent-assisted work.
Cloudberry is licensed under the Apache License, Version 2.0. It suits organizations already running Greenplum who want a maintained successor on a newer kernel, and analytics teams who need MPP scale without a proprietary warehouse.
