+
+2025 has been a defining year for Apache Cloudberry (Incubating).
+Over the past twelve months, the project and its community have made steady
and meaningful progress across releases, governance, infrastructure, and
ecosystem growth.
+
+This post looks back at the key milestones of Apache Cloudberry in 2025 and
reflects on how the project has evolved since entering the Apache Incubator.
+
+## From Proposal to Incubation
+
+Apache Cloudberry officially entered the Apache Incubator in October 2024.
+Following the successful vote, the project completed the migration of its
source code repositories and infrastructure to the Apache Software Foundation
in November 2024.
+
+This initial phase focused on establishing a solid foundation under the ASF:
+
+* Migrating repositories and CI infrastructure
+* Completing project renaming and branding updates
+* Aligning documentation and workflows with ASF policies
+* Starting systematic code cleanup and compliance work
+* Gathering broad community feedback and discussing the roadmap in depth
+
+These efforts set the stage for sustained development and growth throughout
2025.
+
+## First Apache Release: Cloudberry 2.0.0 (Incubating)
+
+One of the most important milestones in 2025 was the release of Apache
Cloudberry (Incubating) 2.0.0 in August 2025 — the project's first official
Apache release.
+
+Leading up to this release, the community completed several major efforts:
+
+* Cherry-picking and consolidating large portions of the archived Greenplum
open-source codebase
+* Completing ASF license and compliance requirements (LICENSE, NOTICE, RAT
audits)
+* Cleaning up legacy files and restructuring the repository
+* Building a new, Apache-compliant CI/CD workflow
+* Running multiple release candidate (RC) rounds and addressing review
feedback from the Incubator community
+
+A major highlight of this release cycle was the introduction of the PAX
(Partition Attributes Across) storage engine, a row-column hybrid format that
optimizes performance for mixed workloads—a significant innovation contributed
back to the core.
+
+The 2.0.0 release marked a major transition from incubation setup to regular,
disciplined Apache-style releases.
+
+For more details, see the [release
announcement](/blog/announce-apache-cloudberry-2.0.0) and [What's New in Apache
Cloudberry 2.0.0](/blog/whats-new-in-apache-cloudberry-2.0.0).
+
+## Community Growth
+
+Community is the heartbeat of any Apache project, and 2025 saw the Cloudberry
family grow stronger and more diverse.
+
+During the year, the Cloudberry Podling Project Management Committee (PPMC)
was proud to welcome four new committers:
+
+* [Xiong Tong](/blog/welcoming-xiongtong-as-a-new-apache-cloudberry-committer)
+* [Wenchao
Zhang](/blog/welcoming-wenchaozhang-as-a-new-apache-cloudberry-committer)
+* [Xun Gong](/blog/welcoming-xungong-as-a-new-apache-cloudberry-committer)
+* [Leonid
Borchuk](/blog/welcoming-leonid-borchuk-as-a-new-apache-cloudberry-committer)
+
+Mailing list discussions, GitHub issues, and design conversations continued to
be kept active, covering topics such as kernel upgrades, performance
improvements, extensions, and ecosystem integration.
+
+The project has also emphasized transparent governance, clear contribution
guidelines, and mentoring new contributors as part of its incubation journey.
+
+## Community Activities and Events
+
+Apache Cloudberry community members were active across a wide range of global
and regional events in 2025, including:
+
+* PostgresConf Global 2025
+* Flink Forward Asia 2025
+* Community Over Code Asia 2025
+* PostgreSQL and data community meetups in Asia, Europe, and North America
+
+In addition to conference talks, the community members organized and
participated in Apache Cloudberry Meetups in multiple cities, providing
opportunities to share technical updates, discuss roadmap items, and introduce
the Apache way to new users and contributors.
+
+These activities helped increase the project's visibility and attracted new
participants from the broader PostgreSQL and data ecosystem.
+
+## PostgreSQL Kernel Upgrade: PG 14 → PG 16
+
+In 2025, the project also initiated the PostgreSQL kernel upgrade, moving
Apache Cloudberry from PostgreSQL 14.x toward PostgreSQL 16.x.
+
+This effort represents a significant technical investment and includes:
+
+* Merging the new PostgreSQL kernel into Cloudberry work branches
+* Resolving conflicts introduced by Cloudberry's MPP architecture
+* Incrementally restoring build, initialization, and test coverage
+* Validating parallel execution and regression test suites
+
+The kernel upgrade work remains ongoing, but important milestones — including
successful cluster startup — were achieved during the year. This challenging
effort is expected to be completed in early 2026.
+
+If you're interested in contributing to this effort, check out the [kernel
upgrade discussion on the mailing
list](https://lists.apache.org/[email protected]) and the
[GitHub Project board](https://github.com/orgs/apache/projects/497).
+
+## Ecosystem and Integrations
+
+The Apache Cloudberry ecosystem expanded significantly in 2025, driven by a
"Upstream first" philosophy.
+
+### Native Integrations
+
+Several widely used tools now provide native support for Cloudberry, including:
+
+* [DBeaver](https://dbeaver.io/): For seamless database management and SQL
development.
+* [WAL-G](https://github.com/wal-g/wal-g): Enabling robust disaster recovery
and continuous archiving.
+* [Apache
SeaTunnel](https://seatunnel.apache.org/docs/2.3.12/connector-v2/source/Cloudberry):
Facilitating high-performance data integration.
+* [Flink JDBC Connector](https://github.com/apache/flink-connector-jdbc)
(v3.3.0+): Supporting real-time streaming data ingestion.
+
+### Community-Maintained Extensions
+
+The community also maintains a set of adapted extensions for Cloudberry:
+
+* [PostGIS for Cloudberry](https://github.com/cloudberry-contrib/postgis):
Upgraded to PostGIS 3.3.2, unlocking advanced geospatial analytics capabilities.
+* [kafka_fdw for Cloudberry](https://github.com/cloudberry-contrib/kafka_fdw):
Enabling efficient real-time data processing from Kafka.
+* [cbcopy](https://github.com/cloudberry-contrib/cbcopy): Supporting migration
from Greenplum to Cloudberry.
+* [ParadeDB for Cloudberry](https://github.com/cloudberry-contrib/paradedb):
Enabling search and analytics workloads on Cloudberry.
+* [pgvector for Cloudberry](https://github.com/cloudberry-contrib/pgvector):
Upgraded to version 0.8, enabling similarity search capabilities.
+
+### Cross-Project Collaboration
+
+Work is actively underway to add native Apache Cloudberry support to Apache
MADlib, strengthening Cloudberry's position in advanced analytics and machine
learning workloads. This collaboration highlights the strength of the Apache
ecosystem, where projects work together to deliver integrated solutions.
+
+## Repository Consolidation
+
+To streamline the developer experience, the community consolidated several
sub-repositories: `cloudberry-gpbackup` was renamed to `cloudberry-backup`, and
the [S3 plugin](https://github.com/apache/cloudberry-gpbackup-s3-plugin) was
merged into the main backup repository.
+
+Furthermore, `apache/cloudberry-devops-release` and
`apache/cloudberry-bootcamp` were integrated into the main Cloudberry
repository under the
[`devops/`](https://github.com/apache/cloudberry/tree/main/devops) and
[`devops/sandbox`](https://github.com/apache/cloudberry/tree/main/devops/sandbox)
directories, respectively.
+
+## Looking Ahead
+
+As 2025 comes to a close, Apache Cloudberry stands on a much stronger
foundation than it did a year ago:
+
+* A completed first Apache release
+* A growing and more diverse contributor community
+* Active participation in global open-source events
+* Ongoing kernel modernization
+* An expanding ecosystem of integrations
+
+The project will continue focusing on community growth, regular Apache
releases, technical stability, and progress toward graduation from the Apache
Incubator.
+
+We would like to thank all contributors, mentors, and community members who
helped make 2025 a productive and rewarding year for Apache Cloudberry.
