+
+This Cloudberry incubation report summarizes our major progress from February
2026 to April 2026. It is adapted from the [Apache Incubator Report May
2026](https://cwiki.apache.org/confluence/display/INCUBATOR/May2026#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?
+
+ - The community continued the Apache Cloudberry bi-weekly community meeting,
holding five public meetings from February to April 2026. These meetings
covered release coordination, kernel upgrades, ecosystem projects, testing
strategy, events, and open community topics.
+ - New Committers: Xiaoyu Liu (@misterRaindrop), Nikolay Antonov (@ostinru),
Robert Mu (@robertmu)
+ - New PPMC Member: Leonid Borchuk
+ - Community channels:
+ - Created a new Slack workspace and a new Discord server after the
previous Slack workspace became unavailable.
+ - Updated the website and planned updates across related repositories to
point users to the current communication channels.
+ - Governance and community process:
+ - Started discussion on an AI conduct policy to guide responsible use of
LLM tools while following ASF copyright and attribution expectations.
+ - Added a website page documenting how to invite new PPMC members.
+ - Events and outreach:
+ - Community Over Code Asia 2026: around 11 Cloudberry-related proposals,
now waiting for the review results. Plan to organize one in-person community
gathering in Beijing during the conference.
+ - A Cloudberry meetup was organized in Moscow, with public recordings and
a Russian Habr article bringing more user feedback to the community.
+ - Two community members were confirmed as PGConf.dev 2026 speakers.
+ - New contributors appeared in community discussions and PRs, including
contributions around Cloudberry Backup, PXF, and core repository features.
+
+### How has the project developed since the last report?
+
+ - Released Apache Cloudberry (Incubating) 2.1.0 in April 2026, the project's
second Apache release after entering the ASF Incubator. Convenience RPM/DEB
packages and binary packages were provided for the first time. Manual packages
were made for 2.1.0, and automation is being considered for 2.2.0.
+ - PostgreSQL kernel upgrade:
+ - Started the PostgreSQL 14.x minor-version upgrade work for the 2.x
release branch. The branch progressed from PostgreSQL 14.4 through 14.8, with
later 14.x updates being tracked in the project Kanban.
+ - Continued the PostgreSQL 16 kernel upgrade on the work development
branch. This work is expected to be completed by the end of Q2 2026.
+ - Fixed PostgreSQL upstream CVEs and security-related patches, including
libpq SSL/GSS negotiation error handling.
+ - Core project improvements:
+ - Merged the diskquota extension into the main repository.
+ - Added the gp_stats_collector extension, improving observability and
laying groundwork for dashboard related work.
+ - Added AQUMV exact-match support for multi-table JOIN queries.
+ - Started discussion on an Iceberg subsystem for `datalake_fdw`.
+ - CI, testing, and platform support:
+ - Added Ubuntu 24.04 Docker image and test matrix support.
+ - Continued Rocky Linux 10 support work, with initial build docker images.
The related test matrix support is to be added.
+ - Started discussion on rethinking the testing strategy for better test
efficiency and coverage.
+ - Upgraded Go to 1.24 in Cloudberry development images and related
ecosystem repositories. Newer Go version support is in the discussion.
+ - Started adding Behave tests for gpMgmt tools (WIP).
+ - Ecosystem and sub-repositories:
+ - `cloudberry-pxf`:
+ - Started a roadmap discussion for the PXF project.
+ - Released 2.1.0, the first Apache release for PXF.
+ - Renamed Java packages from `org.greenplum` to `org.apache.cloudberry`
and updated ASF compliance files.
+ - Added Java 17 support and Rocky Linux 9 CI support.
+ - Removed `gradle-wrapper.jar` from source release artifacts and
download/verify it during build for ASF license compliance.
+ - Added or improved JDBC tests using Testcontainers for ClickHouse, MS
SQL, and Oracle.
+ - Upgraded dependencies including Apache AVRO, Apache ORC, Parquet, and
HBase related components, and discussed Java 21 support.
+ - `cloudberry-backup`:
+ - Released 2.1.0, the first Apache release for gpbackup.
+ - Completed migration work from legacy Concourse CI to GitHub Actions.
+ - Added ASF release script support and Cloudberry 2.1 compatibility.
+ - Started a roadmap discussion for the backup project.
+ - Merged gpbackman-related backup management work. The Prometheus
exporter for the gpbackup history database work is in the review process.
+ - `cloudberry-go-libs`:
+ - Tracked a security issue and dependency update needed by related
backup tooling.
+ - Apache MADlib:
+ - Continued collaboration with Apache MADlib to add Apache Cloudberry
support upstream, with community discussion ongoing. See:
https://s.apache.org/bsu9m
+ - Next release: Started early discussion for Apache Cloudberry 2.2.0,
including release manager, release process documentation, packaging automation,
and testing strategy.
