+This Cloudberry incubation report summarizes our major progress during November 2025 to January 2026. It is adapted from the [Apache Incubator Report February 2026](https://cwiki.apache.org/confluence/display/INCUBATOR/February2026#cloudberry), 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.
