note

This Cloudberry incubation report summarizes our major progress during May and July 2025. It is adapted from the Apache Incubator Report August 2025, 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. Publish the first Apache release following ASF release processes.
2. Grow the contributor and community to ensure long-term sustainability.

How has the project developed since the last report?

• Compliance with ASF policy:
  • Renamed greenplum_path to cloudberry-env.sh for better compliance with ASF rules.
  • Updated Apache RAT license metadata for release.
  • Changed PAX's cpp-stub from submodule to subdir to avoid introducing binary files.
  • Changed Python modules for gpMgmt from bundling their source tarballs to downloading them during the build process via pip3 install.
• Working on the first Apache Cloudberry (Incubating) 2.0.0 release:
  • Already had RC1 & RC2 rounds and fixed some license issues, will have an RC3 round for the dev vote and Apache Incubator vote.
• PostgreSQL Kernel upgrade: the community developer has started the kernel upgrade work from PG 14.4 to PG 16.6.
• 130 new commits to main branch since the last report, focusing on performance improvements, bug fixes and new features.
• Ecosystem:
  • Apache SeaTunnel added official connector support for Apache Cloudberry in its latest 2.3.11 release (See https://s.apache.org/baj30).
  • Flink JDBC Connector v3.3.0+ now supports Cloudberry via PR https://s.apache.org/jt29r
• Our GitHub main repo has reached 1k+ GitHub stars!
