What the board has decided about this committee or office, and the reports it filed, most recent first. Generated from the published minutes.
These categorised views are best effort. They are read from the published minutes by a program, and what it can attribute to a committee depends on how each resolution happens to be worded — so a page may be incomplete, and nothing here overrides the minutes themselves. The raw minutes are the source of truth.
Please note. The board approves the minutes of a meeting at the meeting after it, and they are published then - so the most recent meeting is not usually here. ASF Members can read the draft in the board's own repository until it is.

Current project status: At risk
Issues for the board: Can the board provide guidance on the official
protocol for formally proposing the inclusion of Apache MADlib under
the Apache Cloudberry (Incubating) project? Without such inclusion,
the MADlib project is effectively in a state approaching the Apache
Attic.

## Description: The mission of Apache MADlib is the creation and maintenance of software related to a scalable, Big Data, SQL-driven machine learning framework for Data Scientists ## Project Status: Current project status: The project is essentially in a stalled state. Issues for the board: We will be taking forward the discussion to formalize moving Apache MADlib closer to an active community (i.e. Apache Cloudberry (Incubating)) project. Two PMC members Roman Shaposhnik (rvs) and Greg Chase are in support of this initiative. I (Ed Espino) am on the Apache Cloudberry PPMC. I will formalize the discussion the potential move under the Apache Cloudberry umbrella of components (see Plan forward (proposal) below). ## Membership Data: Community changes, past quarter: - No new PMC members. Last addition was Ed Espino on 2023-03-22. - No new committers. Last addition was Ed Espino on 2023-03-23. ## Project Activity: - No releases have taken place. - No releases are planned. ## Community Health: The only communication has been on the PMC level to discuss the project's options moving forward. For reference, this is what was sent with only Roman Shaposhnik and Greg Chase responding: ## Plan forward (proposal) As I have conversations with both projects and communities, I could use some guidance on what process to follow. I have not observed any movement of one project into another. Any guidance would be greatly appreciated. Here is a proposal. Initial Discussion and Consensus Building - First, formalize discussions within both communities through their respective dev mailing lists - Get clear confirmation from the MADlib PMC about their willingness to move under Cloudberry - Document support from both communities' members - Create a written proposal outlining the benefits and technical synergies Technical Assessment - Create an inventory of MADlib's current assets (codebase, documentation, infrastructure) - Identify potential integration points with Cloudberry - Draft a technical migration plan - Consider any naming/branding implications Community Alignment - Share merger details with communities - Address any concerns from either community - Establish how the existing MADlib committers and PMC members would transition - Define the governance model post-merger Apache Infrastructure & Legal - Consult with ASF Legal regarding any IP or licensing considerations - Plan repository migration strategy - Document infrastructure needs (CI/CD, websites, mailing lists) Formal Proposal - Draft a formal proposal for the ASF Board - Current state of both projects - Rationale for the merger - Community support evidence - Technical migration plan - Timeline - Post-merger governance structure Implementation - Get board approval - Execute technical migration - Update documentation and websites - Announce to broader Apache community
## Description: The mission of Apache MADlib is the creation and maintenance of software related to a scalable, Big Data, SQL-driven machine learning framework for Data Scientists ## Project Status: Current project status: At Risk - The project is mostly inactive due to the resignation of Broadcom's PMC members, following the decision to transition Greenplum Database and related repositories to a closed-source model. Issues for the board: A few of us, including Roman Shaposhnik (rvs@apache.org), have discussed the possibility of joining the Cloudberry project as a next step. The Apache Incubation proposal for Cloudberry can be found here: https://lists.apache.org/thread/qzfb38dzb1x3cg29snq4doy95gd6pzy8 If joining Cloudberry is not an option, we need to determine if the Cloudberry project can still engage with Apache MADlib to address the gap left by Greenplum Database. ## Membership Data: Apache MADlib was founded 2017-07-18 (7 years ago) There are currently 17 committers and 5 PMC members in this project.

## Description: - Apache MADlib is a scalable, big data, SQL-driven machine learning framework for data scientists. ## Project Status: - The project is in a critical state due to several factors (below). - Apache MADlib provides support for PostgreSQL and Greenplum Database. - Without any public announcement from Broadcom or the in the Greenplum open source community, on May 24, 2024, the majority of Greenplum's GitHub repositories have been archived (https://github.com/greenplum-db). The Greenplum slack instance and supporting mail lists have been deactivated. - Broadcom is the corporate backer of the Greenplum Database and supporting components. One of those components is Apache MADlib. - A PMC request for input on the Greenplum closed source move went unanswered. "Input on Validating MADlib Branches and Releases Against Greenplum" - Christofer Dutz performed a roll call (Thu, Jun 13, 2024) of the 12 PMC members, eight members who did not respond were removed from the PMC. ## Community Health: - On July 7th, 2024 - Dianjing Wang, the Community Manager for the Cloudberry Database, a derivative of the Greenplum Database. has expressed interest in contributing Apache MADlib. https://lists.apache.org/list?dev@madlib.apache.org:2024-7 - The Cloudberry Database open source project is currently hosted on GitHub (https://github.com/cloudberrydb).

Shepherd/Mentor notes:
tdunning:
This project seems to be ticking along pretty reasonably. The only worry I
have about it is that it seems to be strongly centered around a few (or
even just one) very strong contributors. That is a worry relative to
longevity and community building. Overall, I don't think that the project
is getting much marginal value from incubation.
johndament:
Its unclear what guidance from the IPMC is required if the podling is
already reaching out to legal, which would be the main thing I can think
of to recommend to them right now.
rvs:
@johndament: I think we need to formalize whatever decision by legal. I'll
create a formal LEGAL JIRA soon.

Big Data Machine Learning in SQL for Data Scientists. MADlib has been incubating since 2015-09-15. Three most important issues to address in the move towards graduation: 1. Produce a first Apache (incubating) release. 2. Expand the community, increase dev list activity and add new committers/pmc members. 3. Execute and manage the project according to governance model required by the "Apache Way”. Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? None How has the community developed since the last report? 1. Second community call held 12/18/15. On the call Roman suggested that the MADlib community do a 1.9 alpha release in the near term. There was general agreement and this is planned for January. A Release Manager has not yet been identified. 2. Material technical conversations on dev mailing lists and in the appropriate JIRAs. E.g., 51 emails on dev in Dec. 3. One new committer has been proposed and voting is under way on the private mailing list. 4. Two comprehensive proposals were posted to the dev mailing list from community members. One relates to the addition of geographically weighted regression (GWR) algorithms. The second involves Bayesian analysis of binomial response models for MPP databases, which makes extensive use of MADlib’s new matrix operations. Both proposals are under active discussion on the mailing list currently. 5. We have been accepted to present a full talk at FOSDEM 2016/Brussels in the HPC, Big Data & Data Science Devroom on Jan 31. The title of the talk is: "MADlib: Distributed In-Database Machine Learning for Fun and Profit" How has the project developed since the last report? 1. 5 JIRAs created and 4 resolved in last 30 days. 2. A SQL API guide has been added to the the MADlib wiki https://cwiki.apache.org/confluence/display/MADLIB/SQL+API+Guide. Date of last release: No release yet. When were the last committers or PMC members elected? One new committer has been proposed and voting is under way on the private mailing list.

None How has the community developed since the last report? 1. First community call held 11/20/15. There were approximately 10 attendees, about half were from outside of the current group of MADlib contributors. This will be a monthly call, possibly moving to 2x per month in the future. 2. Meetup 12/3/15 @ Pivotal Labs, San Francisco: “MADlib and HAWQ for Advanced SQL Machine Learning on Hadoop”. One goal of this meetup is to invite new community participation in MADlib. 3. Material technical conversations are now happening on the dev mailing lists and in the appropriate JIRAs. E.g., 53 emails on dev in Nov compared with 7 in Oct. How has the project developed since the last report? 1. 31 JIRAs created and 7 resolved in last 30 days. 2. Mailing list subscribers: user - 19, dev - 20 3. Proposed scope for first Apache MADlib release has been described to the community for comment. This release includes IP cleanliness and new features. 4. The MADlib wiki <http://s.apache.org/0lQ> has been updated with new content, including a new contributors guideline, an FAQ and a page listing suggestions for first time contributors (these have also been labeled “starter” in the JIRAs). Date of last release: No release yet. When were the last committers or PMC members elected? No new members added on top of the initial committer list.

Meetup 10/29/15 @ Pivotal Palo Alto, CA: “Data Science at Scale for IoT” http://www.meetup.com/Pivotal-Open-Source-Hub/events/225426787/ How has the project developed since the last report? 1. All known issues related to IP cleanliness described in https://wiki.apache.org/incubator/MADlibProposal have been fixed and pushed to the Apache repo. 2. All software activity tracking has migrated to Apache MADlib JIRA from previous tool. 18 JIRAs created and 2 resolved in last 30 days. 3. All commits and code are now being done on the Apache Git repo. 4. Three new quick start guides have been written: i) install, ii) user, and iii) developer. The goal is to make it easier to onboard new community members. 5. A new Greenplum DB sandbox VM with MADlib pre-installed has been created and made available publicly at https://github.com/greenplum-db/gpdb-sandbox-tutorials. The goal is to make it easier to onboard new community members - they can download and start trying MADlib right away with no install/setup. 6. A "catchup JIRA" was filed https://issues.apache.org/jira/browse/MADLIB-912 in order to catch up between the time of the code grand to Apache and bringing in dev work that was already in flight at the time. We apologize for any inconvenience in clubbing together these multiple items; it was a one-time operation. Date of last release: No release yet. When were the last committers or PMC members elected? No new members added on top of the initial committer list.

How has the community developed since the last report? We are approximately 2 weeks into the incubation process. 1. So still at early stage. 2. Most of the core contributors have completed their ICLA's and have established apache ids. 3. Several presentations and meet-ups at ApacheCon EU and Strata NYC to discuss MADlib move to ASF governance. 4. Formal announcements from Pivotal, press briefings and blogs related to the move of the project into Apache aimed at growing awareness and interest in the project. Specialty press have picked up the story and reported widely. How has the project developed since the last report? Early activity: 1. Initial code drop provided to Apache 2. Core infrastructure is in the process of being migrated from existing infrastructure: mailing lists, git, jira, wiki, website Date of last release: No release yet. When were the last committers or PMC members elected? Most of initial list of committers have been on-boarded, some still outstanding. No new members added on top of the initial committer list.
