### IPMC/Shepherd notes:

--------------------
## Caldera

Caldera provides a modular platform for modeling, scripting, and executing
adversary behavior. It allows users to construct emulation plans,
provides agents for communicating with the command and control
server, and enables users to evaluate security detections in a
structured, scalable, and repeatable way. With the use of plug-ins and
community-contributed features, Caldera supports a range of use cases
including adversary emulation, purple teaming, detection
engineering, and continuous security validation. Using Caldera,
defenders can emulate known threat actor behavior and perform other red team
activity to evaluate their organization’s defensive capabilities, test
analytics, and find detection gaps. As a modular tool based on the
MITRE ATT&CK framework, Caldera is designed to be extensible,
intelligence-driven, and automation-friendly.

Caldera has been incubating since 2025-12-19.

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.

### Are there any issues that the IPMC or ASF Board need to be aware of?

No.

### How has the community developed since the last report?

1. Merged 72 commits, most of them - bugfixes and CI/CD improvements.
2. Fixed 2 CVEs.
- CI and infra
1. Added support for Ubuntu 22.04 and Debian packages to CI/CD
2. Added support for Rocky Linux 8 to CI/CD
- Sub-repositories:

project has recently achieved a significant milestone:
1. The code baseline has been 100% aligned with the archived
pxf-archive from GP.
2. Completed full adaptation for Cloudberry.
3. Added a relatively comprehensive and extensive CI pipeline for PXF.
4. Source code cleanup is in progress.
- Squash `cloudberry-bootcamp` repository into `devops/sandbox` in the
main repository catalog.

release Cloudberry 2.1.
- Ecosystem
1. Madlib integration is still in progress. We successfully performed
manual tests, but PR is still open to fix the CI bugs:
https://github.com/apache/madlib/pull/627.
2. Working on diskquota extension integration: still in progress - see
https://github.com/apache/cloudberry/pull/1490.

## Texera

Texera is an open-source system to support collaborative data science, AI,
and ML using GUI-based workflows. Our vision is to develop a
system to support cloud platforms on which users can easily
analyze data and use AI/ML techniques provided as operators.
Users with various backgrounds, irrespective of whether they know coding or
not, can collaborate on the same project to construct a pipeline.
Experienced users can use programming languages such as Python,
R, Java, and Scala to implement customized computation logic.
The platform allows users to pause the execution of a workflow to
investigate the operator states, and resume the execution at a later time.
The platform can be used by a research community to publish
valuable resources such as data sets, workflows, and ML models
to share their domain-specific knowledge and support
reproducibility of scientific research. The platform also allows users to
elastically request computing resources from public clouds for
computationally-intensive tasks.

Texera has been incubating since 2025-04-12.
