note

This Cloudberry incubation report summarizes our major progress during November 2025 to January 2026. It is adapted from the Apache Incubator Report February 2026, 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. Grow the contributor and community to ensure long-term sustainability.
2. Publish a few more Apache releases following the ASF release processes.

How has the community developed since the last report?

• Mailing list Activity: 82 new emails on the Dev mailing list since the last report, covering community, repositories, support, technical and Apache-related discussions.
• GitHub Discussions: 5 new threads since last report.
• New Committers: Rose Duan
• Events:
  • Hosted a Cloudberry community booth at the China Open Source Conference (COSCon'25) in Beijing, Dec 6-7, 2025.
  • Apache Cloudberry Meetup organized in Shenzhen: 30+ attendees on Jan 17th
  • Commenced Apache Cloudberry Bi-weekly Community Meeting, see details in https://s.apache.org/9ba4d, the 1st meeting was held on January 30, 2026.

How has the project developed since the last report?

• PostgreSQL Kernel upgrade (14~>16): at this stage, most of the core enablement work for PostgreSQL 16.9 has been completed. Currently addressing Cloudberry schedule tests.
• Performance
  • PAX: optimize I/O read for multiple discrete columns in a group.
  • Add UDP2 interconnect protocol implementation (right now it is still an experimental feature).
  • Set join_collapse_limit default value to 13.
• Stability
  1. Merged 72 commits, most of them - bugfixes and CI/CD improvements.
  2. Fixed 2 CVEs.
• CI and infra
  1. Added support for Ubuntu 22.04 and Debian packages to CI/CD
  2. Added support for Rocky Linux 8 to CI/CD
• Sub-repositories:
  • cloudberry-pxf. After several months of continuous effort, the PXF project has recently achieved a significant milestone:
    1. The code baseline has been 100% aligned with the archived pxf-archive from GP.
    2. Completed full adaptation for Cloudberry.
    3. Added a relatively comprehensive and extensive CI pipeline for PXF.
    4. Source code cleanup is in progress.
  • Squash cloudberry-bootcamp repository into devops/sandbox in the main repository catalog.
• New release: 2.1
  • Merged 244 commits from main to REL_2_STABLE. We're ready to release Cloudberry 2.1.
• Ecosystem
  1. Madlib integration is still in progress. We successfully performed manual tests, but PR is still open to fix the CI bugs: https://github.com/apache/madlib/pull/627.
  2. Working on diskquota extension integration: still in progress - see https://github.com/apache/cloudberry/pull/1490.
• 2025 Summary and 2026 Overview discussions
  1. Published Cloudberry 2025 Review blog post: https://s.apache.org/fxde8
  2. Initiated Cloudberry 2026 roadmap discussions: https://s.apache.org/jxd7s
