note

This Cloudberry incubation report summarizes our major progress during March and April 2025. It is adapted from the Apache Incubator Report May 2025, with some modifications for readability.

Cloudberry

Cloudberry is an advanced and mature open-source Massively Parallel Processing (MPP) database, derived from the open-source version of Pivotal Greenplum Database®️ but built on a more modern PostgreSQL 14 kernel, whereas Greenplum is based on PostgreSQL 12. This upgrade brings enhanced enterprise capabilities, making Cloudberry well-suited for data warehousing, large-scale analytics, and AI/ML workloads.

Cloudberry has been incubating since 2024-10-11

Three most important unfinished issues to address before graduating:

1. Complete the source code cleanup to ensure ASF compliance.
2. Publish the first Apache release following ASF release processes.
3. Grow the contributor and community to ensure long-term sustainability.

How has the community developed since the last report?

How has the project developed since the last report?

• Create the Wiki space in GitHub to organize the collective knowledge from community practices, including the release process.
• Security:
  • Integrated two code analysis tools to enhance our code quality and identify potential issues in the development process: Coverity Scan and SonarQube Scan.
  • Fix the PostgreSQL security issue CVE-2025-1094.
• CICD:
  • Working on adding the Ubuntu build and test environment support to Cloudberry
• Codebase Updates:
  • Evolve the Cloudberry code following the Roadmap: Contributed back the row-column hybrid storage engine -PAX to the Cloudberry codebase;
  • Completed the first stage of cherry-picking commits from the open-source Greenplum project to Cloudberry (80%+ progress of plan).
  • Work for the first Apache Cloudberry (Incubating) 2.0.0 release
    • Pull Request management through the GitHub project: https://github.com/orgs/apache/projects/490
• License-related updates:
  • Update the NOTICE and LICENSE files.
  • List the third-party licenses under the licenses directory.
  • Replace the Pylint with a license-compatible one - ruff.
  • Update the license headers with the Apache license header for the newly created files.
  • Add RAT license audit config and compliance metadata.
• Brand updates: rebrand old names to the latest Apache Cloudberry brand both in the main codebase and the site source.
• Cleanup the old unused files from the source code for a clearer codebase and ASF compliance (including concourse/*, hd-ci/*, deploy/*, and so on).
