GitHub user jianlirong added a comment to the discussion: why incubating the greenplum database again?
Thanks for the question. The motivation behind Apache Cloudberry comes from several observations about the evolution of the PostgreSQL ecosystem over the past few years. First, Greenplum has accumulated many years of production experience and has been widely adopted across different industries. It also established itself as one of the most mature open-source MPP databases built on PostgreSQL. As the project evolved away from its previous open development model, we felt there was still a strong need in the community for a vendor-neutral, Apache-governed open-source successor that could continue serving users who value openness, long-term sustainability, and community-driven innovation. Second, Apache HAWQ and Apache Cloudberry were created to solve very different problems. HAWQ was designed as a SQL-on-Hadoop engine, with its architecture tightly integrated with the Hadoop ecosystem and based on an older PostgreSQL codebase. Cloudberry, on the other hand, is a distributed MPP database designed for modern analytics workloads, while continuously evolving together with newer PostgreSQL releases. Although the projects share some historical roots, their technical goals and target use cases are fundamentally different. Finally, the analytical database ecosystem has become much richer over the last decade. Excellent systems such as ClickHouse, Doris, and StarRocks have each established their own strengths and communities. At the same time, we continue to see strong demand for an open-source distributed database that combines: 1. close compatibility with modern PostgreSQL, 2. a proven shared-nothing MPP architecture, 3. rich SQL capabilities, 4. enterprise-grade stability and scalability, and 5. an open, community-governed development model. Apache Cloudberry is our effort to meet that demand. Rather than replacing existing systems, we hope to provide another strong option for users and organizations whose requirements align with these goals. Our goal is not to compete with any particular project, but to contribute another healthy and sustainable choice to the open-source ecosystem. We believe that diversity, open governance, and collaboration ultimately benefit both users and the PostgreSQL community as a whole.
