Incubator PMC report for June 2025

The Apache Incubator is the entry path into the ASF for projects and codebases wishing to become part of the Foundation's efforts.

There are currently 35 podlings incubating. In May, podlings executed six distinct releases, and two IP clearances occurred. Several incubating proposals have been discussed and are presently undergoing voting on the mailing list (GeaFlowa and Fluss), and a new project Caldera, is being discussed. We also have one new podling called Burr, and two projects, Gravitinto and StormCrawler graduated last month. One person was added to the IPMC.

No podlings have retired, but a couple are still talking about it. Five podlings failed to report and will be asked to report next month.

Conversations on the list have been focused on releases, new incubating projects, and the incubation process.

Tracking projects that have been incubating for a long time, Annotator is discussing retirement, Nemo is votng for it, and Toree is slowly moving towards graduation. The Livy PPMC has been slow to respond, and there is a roll call to see if they have an active PMC. NLPCraft did report this month, but the roll call sent a month ago has received two responses. Training is ready to graduate.

Finally, note that last month’s incubator report was submitted on time but did not receive sufficient Director sign-offs. It is available here: https://whimsy.apache.org/board/agenda/2025-05-21/flagged/Incubator

Baremaps

Apache Baremaps is a toolkit and a set of infrastructure components for creating, publishing, and operating online maps.

Baremaps has been incubating since 2022-10-10.

Three most important unfinished issues to address before graduating:

  1. Expanding the community
  2. Making releases
  3. Starting the graduation process

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?

There has been an uptick in activity early this year, which has since slowed down. One difficulty we face is related to the onboarding and retention of new contributors. We have a number of easy bug fixes that are suitable for newcomers, but we also have advanced features that require a deeper understanding of the codebase. This can be intimidating for new contributors, leading to a lack of engagement after initial contributions.

How has the project developed since the last report?

We released version 0.8.2 in February 2025. Since then, we have added support for Apache Calcite, which will open the door to spatial SQL queries on various data sources (flatgeobuf, PostGIS, geopackage, geoparquet, etc.). We also fixed a number of bugs and upgraded dependencies.

IPMC/Shepherd notes:

PJF: The BareMaps active community remains small. Possibly, too small to be be able to become a self-managing PMC on graduation.

JM: They have added 3 committers. I would suggest they look to see if any of those or any other committers can be made PPMC members.


BifroMQ

BifroMQ is a Java-based, high-performance, distributed MQTT broker with native multi-tenancy support, designed for large-scale connections and message delivery.

BifroMQ has been incubating since 2025-04-22.

Three most important unfinished issues to address before graduating:

  1. Successful repository migration and completion of the first release process
  2. Website building and grow the community
  3. Complete the Trademark Assignment process

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

Baidu manages the SGA, CCLA, and Trademark Assignment as a unified "Corporate Contract" workflow. The SGA and CCLA documents have been successfully submitted to the ASF.

We are eager to advance the Trademark Assignment process to finalize the Corporate Contract workflow, rather than delaying it until graduation from the incubator.

How has the community developed since the last report?

  • Added 2 contributors since incubation began

How has the project developed since the last report?

  • Two repositories have been transferred to the Apache GitHub organization (apache/bifromq, apache/bifromq-sites).

IPMC/Shepherd notes:


Hamilton

Hamilton is a lightweight in-process framework to define, execute, and observe directed acyclic graphs (DAGs) that express data transformations. In Hamilton one can express complex DAGs of transformations, e.g. from dataframe transformations (using pandas, polars, PySpark), machine learning pipelines, through to regular software engineering API request and LLM API based workflows. Observability hooks are built into the framework. The Hamilton UI is a self- hostable service to captureobservability output from workflow runs. Apache Software Foundation incubation will establish Hamilton as a community-driven standard.

Hamilton has been incubating since 2025-04-12.

Three most important unfinished issues to address before graduating:

  1. Finish repo setup.

IPMC/Shepherd notes:

PJF: The NLPCraft active community is quite small. Possibly, too small to be able to operate as a self-managing PMC on graduation.

JM: The recent roll call got one person who wants to continue development and one who wants to continue mentoring. A dev list email on next steps got no responses. The IPMC may have to consider retiring the project.


OpenServerless

OpenServerless is an open source, cloud-agnostic, serverless platform. It offers a complete environment for serverless applications development, based on Kubernetes. With Apache OpenWhisk as its FaaS engine, it provides an unified developer experience with a plethora of services (SQL or noSQL databases, key-value stores, object storage, LLMs services, function schedulers) managed by the platform's core: the operator, along with tooling (the CLI) to simplify (and interact with) deployments, integrated ide and starter application and optimized runtimes integrated with the staters.

OpenServerless has been incubating since 2024-06-17.

Three most important unfinished issues to address before graduating:

  1. Strengthen the community
  2. Assess the requirements for the First Release
  3. continue the process of documenting the entire platform.

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. The Apache OpenServerless and AI course - currently in Italian - was completed by at least a couple hundred developers and some of them are using actively the platform.
  2. The AI course is being extended to support also MCP api.
  3. Two new contributors joined the projects.
  4. We're in the process of release some videos to show installation on local machines and cloud servers.
  5. We've published an article on the

[Opensource.net](https://opensource.net/apache-openserverless-is-the-easiest -way-to-build-your-cloud-native-ai-application/) blog.

How has the project developed since the last report?

  1. We improved various parts of the project, fixing bugs and reviewed the documentation.
  2. Closed 19 issues. Opened 6 new issues.
  3. Improved the OpenServerless streamer (openserverless-streamer), introducing new code and documentation.
  4. Preparing an upgrade to OpenWhisk 2.
  5. We have opened a new PR towards the Apache OpenWhisk project to support JDK17 based builds.
  6. We have added a new openserverless-build project with the objective of preparare OpenWhisk 2 multiplatform images tailor made for our project and we aim to provide a native executable for the standalone component, with the objective of providing a lighter development environment.

IPMC/Shepherd notes:


Otava

Apache Otava (incubating) performs statistical analysis of performance test results stored in CSV files, PostgreSQL, BigQuery, or Graphite database. It finds change-points and notifies about possible performance regressions.

A typical use-case of otava is as follows:

  • A set of performance tests is scheduled repeatedly, such as after each commit is pushed.
  • The resulting metrics of the test runs are stored in a time series database (Graphite) or appended to CSV files.
  • Otava is launched by a Jenkins/Cron job (or an operator) to analyze the recorded metrics regularly.
  • Otava notifies about significant changes in recorded metrics by outputting text reports or sending Slack notifications.
  • Otava is capable of finding even small, but persistent shifts in metric values, despite noise in data. It adapts automatically to the level of noise in data and tries to notify only about persistent, statistically significant changes, be it in the system under test or in the environment.
  • Otava has been incubating since 2024-11-27. Otava entered Incubation as Hunter. The project name Otava was approved by VP Brand 2025-02-09.

Three most important unfinished issues to address before graduating:

  1. Publish the first release under the new name. ( htts://s.apache.org/ahsxx) We are still iterating on getting Incubator PMC passed.
  2. Publish the existence of Apache Otava (Incubating), and our first release.
  3. ???

How has the community developed since the last report?

Unchanged. Everone is now waiting for the first release.

Henrik participated in International Conference on Performance Engineering 2025 and gave a short presentation on the 8 year history of Otava. (The talk had initially been proposed to the conference before we became and Apache incubating project. We learned of some users that we weren't previously aware of. Most notably Red Hat uses Otava (née Hunter) to analyze performance test results from OpenShift.

How has the project developed since the last report?

We are focused on making our first release.

Polaris is a catalog for data lakes. It provides new levels of choice, flexibility and control over data, with full enterprise security and Apache Iceberg interoperability across a multitude of engines and infrastructure.

Polaris has been incubating since 2024-08-09.

Three most important unfinished issues to address before graduating:

  1. Finalize "complete" release (including binary distributions and artifacts), and adopt regular releases pace
  2. Grow the community
  3. Fill out the maturity model

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?

Regarding the user community:

  • On Slack, since March, we have 17 threads from new users (28 new users in May, 53 new users in April, 53 new users in March)
  • On GitHub Issues, we had 11 new issues created by new users.
  • On the dev mailing list, we had 196 messages in March, 144 in April, 279 in May, mostly from Polaris committers/contributors. It seems the users prefer to ask questions on Slack.

Regarding the dev community:

  • We had 7 Pull Requests from 7 new contributors
  • We are discussing with the Apache XTable community (for multi table formats support)
  • Community meetings happened on 2025-04-03 and 2025-04-17 (recorded and publicly available)

In order to build/grow the Polaris community, we participated to different events (meetups, etc) to introduce Apache Polaris:

  • Open Source Data Deep Dive: London (2025-05-21)
  • Current 25 London (2025-05-20)
  • Open Source Data Deep Dive: Barcelona (2025-05-15)
  • Munich Database Meetup: Analytics Data Stack (2025-05-13)

How has the project developed since the last report?

We added the polaris-tools repo (https://github.com/apache/polaris-tools) to host parts of the project (benchmark tool, catalogs migrator, ...) not directly related to the Polaris "catalog server".

Highlights in the project developed:

  • We refactored the persistence layer to use pure JDBC now and we deprecated EclipseLink use.
  • We are working on gather server and tool in an unique distribution
  • Several proposals are in discussion right now (event/observe API, async tasks, spark client, ...)

In preparation for 1.0-incubating release, we are voting 0.10-incubating release. We are focusing on 1.0-incubating release, the release process should start quickly after 0.10-incubating release vote pass.

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 that supports 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 operator states and resume 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.

Three most important unfinished issues to address before graduating:

  1. Complete the SGA form.
  2. Donate the Texera codebase from the Texera/texera GitHub repo to the Apache/Texera repo.
  3. Set up the Apache Texera webpage http://texera.apache.org/.

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?

  • 2025-04-12: The project enters the incubation phase.

  • 2025-05-12: We have expanded our PPMC members to 12 members. All of them have signed and submitted their iCLA forms. The latest members (excluding mentors) are listed as follows:

  • 2025-05-12: 10/12 PPMC members (excluding two mentors) have subscribed to mailing lists.

  • 2025-05-18: We have gathered 52 approvals (in the form of email replies) from past codebase committers to donate the Texera/texera codebase to Apache/Texera.

  • 2025-05-25: We are in discussion with Ian Maxon (Apache ID: imaxon), PMC Chair of Apache AsterixDB and a long-time contributor, about his joining as a mentor for Apache Podling-Texera. Ian is currently in the process of self-nominating to join the Incubator PMC in order to become eligible to serve as a mentor.

  • 2025-06-01: As Texera is a research project conducted at University of California, Irvine (UCI), the university owns the copyright of the codebase/software. We are talking to the UCI licensing office about releasing their copyright to the committers of the codebase, with Chen Li as the representative. After the UCI licensing office releases the copyright, we will prepare the SGA form.

  • 2025-06-01: As of today, we are actively designing a new logo for Texera.

When were the last committers or PPMC members elected?

On 2025-05-12, the last Texera PPMC members (yunyad, aicam) were added.

Have your mentors been helpful and responsive?

Yes, our mentors have been both helpful and highly responsive. We are grateful for their continued support throughout the incubation process. In particular, we would like to extend a special thanks to PJ Fanning for his outstanding guidance and engagement.

Is the PPMC managing the podling's brand / trademarks?

Texera PPMC is working with third parties who are willing to use Texera brand/trademarks, according to https://incubator.apache.org/guides/publicity.html and https://incubator.apache.org/guides/branding.html. Texera PPMC is also working on a new design of the Texera logo/trademark. Name is approved: https://issues.apache.org/jira/browse/PODLINGNAMESEARCH-233

Training

The Training project aims to develop resources which can be used for training purposes in various media formats, languages and for various Apache and non-Apache target projects.

Training has been incubating since 2019-02-21.

For the last few months we have been discussing graduation, and getting our various ducks in rows. We believe we are ready to graduate, but have only four people who have elected to stay on as PMC members, which seems to us too small a number. So right now we are discussing what the next steps are -- go ahead and graduate, or attempt to grow that number a little.

Three most important unfinished issues to address before graduating:

A. Grow the community a little more. -- or -- B. Decide that a small dedicated community is better than languishing in obscurity forever.

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

None

How has the community developed since the last report?

While discussing graduation, we had a number of people indicate that they are no longer engaged enough to move to that final step.

How has the project developed since the last report?

We have continued to slowly work on content. And one of our number got a talk accepted at Community Over Code 2025 to present about the project, so hopefully several of us will be there for that.

How would you assess the podling's maturity?

We believe that we're ready to move out of our parents' basement and into the real world. Any day now.

  • [ x ] Nearing graduation

Wayang

Wayang is a cross-platform data processing system that aims at decoupling the business logic of data analytics applications from concrete data processing platforms, such as Apache Flink or Apache Spark. Hence, it tames the complexity that arises from the "Cambrian explosion" of novel data processing platforms that we currently witness.

Wayang has been incubating since 2020-12-16.

Three most important unfinished issues to address before graduating:

  1. Working on one more release before graduation.

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 more PPMC member, 7 new contributors, 1 new slack member since the last report.

How has the project developed since the last report?

Progress on multiple fronts:

  • Upgraded to Java 17
  • Extended functionality for Wayang's ML capabilities
  • Extended functionality for Wayang's FL capabilities
  • Extended functionality for Wayang's Scala API
  • Extended functionality for Wayang's SQL API
  • Several new operators
