--- title: "Apache Cloudberry Incubation Report - May 2026" description: "We’re making steady progress to grow!" source: https://cloudberry.apache.org/blog/apache-cloudberry-incubation-report-202605 --- # Apache Cloudberry Incubation Report - May 2026 :::note 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. ### How would you assess the podling's maturity? - [ ] Initial setup - [ ] Working towards first release - [X] Community building - [ ] Nearing graduation - [ ] Other: ### Date of last release: - April 14, 2026 - Apache Cloudberry (Incubating) 2.1.0 ### When were the last committers or PPMC members elected? - March 24, 2026 - Xiaoyu Liu (@misterRaindrop), Nikolay Antonov (@ostinru), Robert Mu (@robertmu) were announced as new committers. - April 07, 2026 - Leonid Borchuk was announced as a new PPMC member. --- ## Join Us Apache Cloudberry follows the principle of open and transparent governance.
