+
+:::note
+Apache Cloudberry 2.1.0 is currently under community vote and has not been
officially released yet. This post highlights several changes included in the
current release candidate. Final contents may still change before the release
is approved.
+:::
+
+Apache Cloudberry (Incubating) 2.1.0 continues the project's work on database
kernel improvements, ecosystem modernization, and ASF-oriented release
engineering. Based on the current release candidate, this upcoming version
includes changes across the core database, Apache Cloudberry PXF, and Apache
Cloudberry Backup.
+
+This article is a preview rather than an official release announcement, so it
focuses on a few representative updates instead of a complete changelog.
+
+## Apache Cloudberry Core (`apache/cloudberry`)
+
+The core repository in 2.1.0 includes both user-facing improvements and
behind-the-scenes engineering work.
+
+It is important to emphasize that 2.1.0 is built on a **stable branch**. The
community is currently undertaking an effort to upgrade the underlying
PostgreSQL core from version 14.4 to the latest 14.22. This approach ensures
that the database receives essential kernel updates while maintaining strict
stability. While 2.1.0 does not include the entirety of this massive upgrade,
these updates will be included in the future 2.x release.
+
+### Selected kernel and performance updates
+
+- **UDP2 interconnect:** 2.1.0 adds a new UDP2 interconnect protocol
implementation, continuing work on the interconnect layer and distributed
execution path.
+- **MCP server:** The release candidate adds an MCP server for Cloudberry,
making it easier to connect Cloudberry with LLM-based tools and workflows.
+- **PAX improvements:** PAX gains support for `LZ4` compression for table
columns, along with I/O and memory-management refinements.
+- **Fast `ANALYZE` for AO tables:** The release candidate introduces fast
`ANALYZE` for append-optimized tables, targeting a common operational pain
point for large analytical workloads.
+- **ORCA optimizer work:** 2.1.0 includes a series of ORCA improvements such
as CTE pruning, partial aggregate pushdown below joins, and multiple
correctness and memory-leak fixes.
+- **Runtime filter pushdown:** Runtime filter pushdown work continues in this
cycle, including support for pushing filters down to Table AM and related fixes.
+
+### Developer workflow and release engineering
+
+- **Release-branch testing and ASF checks:** The project added binary swap
testing for the `REL_2_STABLE` branch and expanded Apache RAT-related audit
checks in CI.
+- **Sandbox and developer tooling:** The earlier
`apache/cloudberry-devops-release` and `apache/cloudberry-bootcamp` work has
been integrated into the main repository under `devops`, and the sandbox gains
a local mode for development and validation.
+- **Environment naming transition:** In 2.1, the environment setup has
completed the move from `greenplum_path.sh` to `cloudberry-env.sh`. For
background on that transition, see [Goodbye `greenplum_path.sh`, Hello
`cloudberry-env.sh`: A Phased Transition
Plan](https://cloudberry.apache.org/blog/from-greenplum-path.sh-to-cloudberry-env.sh).
+- **Compression and dependency cleanup:** The codebase also removes support
for QuickLZ, encouraging the use of maintained alternatives such as `zlib` or
`zstd`.
+
+There are many other fixes in areas such as hot standby, disaster recovery,
utilities, CI portability, and testing. For a broader view of the current
release candidate, see the [core branch
comparison](https://github.com/apache/cloudberry/compare/2.0.0-incubating...2.1.0-incubating-rc2).
+
+## Apache Cloudberry PXF (`apache/cloudberry-pxf`)
+
+Apache Cloudberry PXF is one of the clearest examples of ecosystem
modernization in the 2.1.0 cycle.
+
+First, the codebase has been realigned with the archived
`greenplum/pxf-archive` baseline, and Cloudberry-specific support has been
ported onto that newer base for Cloudberry 2.1. The repository also received
ASF-oriented cleanup, including updates to `DISCLAIMER`, `LICENSE`, and
`NOTICE`, as well as removal of the pre-bundled `gradle-wrapper.jar`.
+
+Second, the project has refreshed its engineering workflow. Legacy Concourse
CI files have been removed in favor of a refactored and robust CI layout
oriented around current Cloudberry development and testing.
+
+Third, 2.1.0 continues the broader Cloudberry branding refresh. Java package
declarations move from `org.greenplum` to `org.apache.cloudberry`, and the Go
library dependency references are updated to `apache/cloudberry-go-libs`.
+
+PXF also includes a substantial set of dependency and connector updates in
this cycle:
+
+- Apache Avro is updated to newer Java 8 compatible versions, with added
`zstd` support in tests and related automation.
+- Apache ORC is updated to `1.7.11`.
+- Parquet is updated first to `1.12.3` and later to `1.15.2`, adding support
such as `ZSTD`, `LZ4_RAW`, and vectored I/O improvements.
+- HBase client support is updated from `1.3.2` to `2.3.7`.
+
+For more detail, see the [PXF branch
comparison](https://github.com/apache/cloudberry-pxf/compare/1.6.0...2.1.0-incubating-rc2).
+
+## Apache Cloudberry Backup (`apache/cloudberry-backup`)
+
+Apache Cloudberry Backup also sees significant repository and tooling work in
the current 2.1.0 release candidate.
+
+The project has been renamed from `cloudberry-gpbackup` to
`cloudberry-backup`, and its codebase has been aligned with the archived
`greenplum/gpbackup-archive` baseline while preserving Cloudberry-specific
adaptation for Cloudberry 2.1. Dependency references have also been updated
from `gp-common-go-libs` to `apache/cloudberry-go-libs`.
+
+One practical usability change is that the archived `gpbackup-s3-plugin` has
been merged into the main repository under `plugins/s3plugin`, reducing the
amount of separate setup required for S3-based backup workflows.
+
+The repository also continues the project's ASF-oriented cleanup work,
including updates to LICENSE and NOTICE files, removal of legacy files, and
modernization of CI coverage for unit, integration, end-to-end, S3 plugin, and
scale-related testing.
+
+For the complete set of changes in the current release candidate, see the
[Backup branch
comparison](https://github.com/apache/cloudberry-backup/compare/1.6.0...2.1.0-incubating-rc2).
+
+## Looking Ahead
+
+Even before the 2.1.0 vote is complete, the current release candidate already
shows the project's direction clearly: continued kernel work in the main
database, modernization of surrounding components, and a cleaner foundation for
future community development.
+
+If the release is approved, the project will share the official release
announcement and related materials through the website and community channels.
Until then, this post should be read as a preview of the current release
candidate rather than the final release notes.
+
+We welcome everyone to continue following and participating in the Apache
Cloudberry community to witness the 2.1.0 release:
