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.

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:

Upgrade to support the latest versions of Python, including upgrading to the latest signal-processing-algorithms library.
Do more releases, so that it is a routine, repeatable process.
Grow the community and ultimately vote to admit new committers and PPMC members. Do more publicity around the releases and the project in general. This is an item where we certainly hope to see new contributors.

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?

We've seen engagement in the mailing lists and/or PRs from four out of five of the project's committers since the last report.

Three new contributors have reached out via the mailing list and/or GitHub, showing interest in the project and starting work on open issues.

How has the project developed since the last report?

We have completed our first release.
Updated our build system to use uv instead of poetry.
Changed our configuration management for ease of use.
Starting the work to migrate to modern python versions.

How has the community developed since the last report?

Regarding the user community:

On Slack, we note an increase of 7% of the number of messages (with a peak of 580 messages during last month). These Slack messages happen 77% on public channels and 21% as direct messages (which is a good ratio). NB: we are using the free plan for Slack, meaning that the messages retention is 90 days. It's interesting to note that we got messages from 21 threads started by new Slack users.
On GitHub Issues, we had 19 issues created by new users.
On the dev mailing list, we had 196 messages in August, 278 messages in July, and 311 messages in June.

Regarding the dev community:

We had 46 Pull Requests from 13 new contributors
Community meetings happened on 2025-06-12, 2025-06-26, 2025-07-24, 2025-08-28, all recorded and shared publicly (on the dev mailing list and the website, see https://polaris.apache.org/community/meetings/)

We participated in events to promote Apache Polaris:

Apache Beam Summit 25 New York City
Apache Iceberg Meetup Paris June 25
Snowflake Summit SF June 25
Data and AI - Lakehouse MiniSummit SF June 25

How has the project developed since the last report?

We released 1.0.0-incubating, which is an important milestone for the podling:

Binary distributions (.tgz/.zip) and Docker images
Official Helm chart for Kubernetes
Quarkus runtime for fast startup
Policy store with built-in data TMS policies
Rollback compaction on conflicts
3rd Party IdP integration
Federation and generic table support (experimental)

We also released 1.0.1-incubating, mostly to fix an issue on the Helm chart.

In order to faster ship fixes and new features, we agreed about a monthly release cadence.

We are also discussing several proposals:

Table Source
Client/Authentication API
Event API
Async & Reliable Tasks
Commit Deconfliction
Row and Column Based Access Control
S3 Remote Signing
FGAC

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.

Three most important unfinished issues to address before graduating:

Set up the Apache Texera webpage http://texera.apache.org/. Work is underway to consolidate user guides, developer setup instructions, and governance policies. We are analyzing the documentation structures of successful projects like Apache Flink and Spark to ensure an optimal user experience.

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?

August 06, 2025: The repository has officially transferred to Apache organization
August 28, 2025: We conducted our monthly group sync meeting with the PPMC members, committers, and contributors.

How has the project developed since the last report?

Cloud Deployment: Investigated on AWS ECS for low cost deployment of Texera.
Preparing for NIH: Added option to allow owner to give download access to public datasets.
UI Enhancements:
- Added user's activeness to admin dashboard
- Displayed file upload speed and time
- Added dashboard tab for computing units
Docs: All design decisions are documented in issues tab in Github.

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.
