Apache Cloudberry (Incubating), created by the original developers of Greenplum® Database, is one advanced and mature open-source Massively Parallel Processing (MPP) database, which evolves from the open-source Greenplum® Database but features a newer PostgreSQL kernel and more advanced enterprise capabilities. It can serve as a data warehouse and can also be used for large-scale analytics and AI/ML workloads.
You can follow these guides to build Cloudberry on Linux OS (including RHEL/Rocky Linux, and Ubuntu) and macOS.
Welcome to try out Cloudberry via building one Docker-based Sandbox, which is tailored to help you gain a basic understanding of Cloudberry's capabilities and features.
This is the main repository for Apache Cloudberry (Incubating). Alongside this, there are several ecosystem repositories for Cloudberry, including the website, extensions, connectors, adapters, and other utilities.
- apache/cloudberry-site: website and documentation sources.
- apache/cloudberry-backup: backup utility for Cloudberry.
- apache/cloudberry-go-libs: go-libs for Cloudberry.
- apache/cloudberry-pxf: Platform Extension Framework (PXF) for Cloudberry.

Thanks to PostgreSQL, Greenplum Database and other great open source projects to make Apache Cloudberry has a sound foundation.
Cloudberry is licensed under the Apache License, Version 2.0. For details, see the LICENSE.
This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org for more information.
The Apache Software Foundation has classified this software as Export Commodity Control Number (ECCN) 5D002, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the "publicly available" Section 742.15(b) exemption (see the BIS Export Administration Regulations, Section 742.15(b)) for both object code and source code.
The following provides more details on the included cryptographic software:
- Apache Cloudberry uses OpenSSL for TLS support on client and server connections, and for the SCRAM-SHA-256 authentication method.
- Apache Cloudberry optionally uses GSSAPI (Kerberos) for authentication and connection encryption, and LDAP over TLS for authentication.
- The bundled
pgcryptoextension provides cryptographic functions to SQL, using either OpenSSL or its own built-in implementations. - The
gpfdistexternal table file server can serve over HTTPS, using OpenSSL and X.509 certificates supplied through its--ssl <certificates_directory>option.
Apache Cloudberry does not ship OpenSSL itself; it links against the OpenSSL provided by the operating system.
Apache Cloudberry is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required for all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
