# Incubator PMC report for March 2026
The Apache Incubator is the entry path into the ASF for projects and
codebases wishing to become part of the Foundation's efforts.
As of February, there are 28 podlings under incubation. Five releases were
made during the month, and no IP clearances were completed. Two podlings
graduated, Gluten and Polaris, and no podlings retired. However, there are
votes underway to retire BareMaps and HoraeDB. There were no additions or
removals to IPMC membership.
Mailing list traffic during the month focused on release voting, graduation
discussions and votes on retirement.
Auron was invited to take part in a 6-month review. Iggy also requested to
participate in a review.
Most podlings continue to make steady progress toward graduation. Caldera
is off to a slow start. Livy has voted to graduate on its mailing list, and
Toree's latest release seems to be taking longer than expected. ResilientDB
is likely to graduate soon.
Pegasus is still experiencing some community difficulties and may need
follow-up.
There is some concern about the progress of OpenServerless, as they state
they are nearing graduation, but have not made a release.
Two podlings, Caldera and OzHera, failed to submit a report and will be
asked to report next month. All submitted podling reports had mentors'
sign-off.

## 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. Increase public exposure to expand the community user base and improve
project visibility.
2. Continue delivering regular releases, streamline the release
management process, and rotate the Release Manager role among key
contributors.
3. Grow community participation beyond the original contributors,
including attracting new reviewers and contributors.
### Are there any issues that the IPMC or ASF Board need to be aware of?
We understand that the trademark transfer has been completed based on
publicly available trademark ownership information (e.g. via
https://aiqicha.baidu.com/mark/s?q=BIFROMQ&t=7).
However, we would appreciate receiving an official confirmation from ASF (a
scanned copy of the signed transfer agreement would be sufficient) so that
our company can properly archive the transfer documentation for internal
compliance purposes.
### How has the community developed since the last report?
We have observed increasing activity on GitHub and the dev@ mailing list.
Our mentor (Chris) helped initiate a valuable discussion with the Apache
IoTDB community, which may lead to potential collaboration between the two
projects.
We have set up a WeChat Account (“BifroMQ”) to publish Chinese translations
of release announcements. All published content is derived from or links
back to the official Apache BifroMQ website, and the account is not used
for community discussions.
### How has the project developed since the last report?
We completed our first incubating release after 3 RC votes.

Our mentors have been helpful and responsive.
### Is the PPMC managing the podling's brand / trademarks?
Are 3rd parties respecting and correctly using the podlings
name and brand? If not what actions has the PPMC taken to
correct this? Has the VP, Brand approved the project name?
We attempted to rename our WeChat account by adding the “Apache” prefix,
based on PPMC consensus reached on the private mailing list. However, the
request was rejected by the WeChat platform due to tightened naming
policies, which now require an official authorization document from ASF to
use “Apache” as an account prefix.
We would appreciate guidance on whether there is a formal ASF process to
request such an authorization letter for external platform compliance
purposes.

## 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. reactivate the build system that was phased out because of expired
cloud credits - Nuvolaris provided the resources and we requestes also
2. create a self-contained distribution that builds from sources -
already in place a kit to do that creating images in a local docker and the
loading into a cluster
3. embed tasks in the cli binary as we cannot distribute something that
self-updates from the cloud
### Are there any issues that the IPMC or ASF Board need to be aware of?
we are asking for resources to AWS to test in cloud
### How has the community developed since the last report?
New contributors and more adopters, including cloud providers like the
Italian Government Cloud, the Polo Strategico Nazionale and 2 cloud italian
### How has the project developed since the last report?
We are completing the major features like the devcontainer and the embedded
registry for custom actions auto-created

lists. It would be great to have an update and plan.
- [X] (openserverless) PJ Fanning
Comments: No obvious progress on a 1st release and podling is nearly 2
years old. Mailing list traffic is minimal. Really just GitHub automated
msgs. I would disagree with the report's assertion that the podling is
nearing graduation.
### IPMC/Shepherd notes:
--------------------
## Otava
Apache Otava (incubating), a command-line tool, written in Python, detects
and alerts about statistically significant changes in performance test
results (more generally, time-series data) stored in CSV files or a number
of supported databases.
A typical use-case of Otava is as follows:
1. A set of performance tests is scheduled repeatedly, such as after each
commit is pushed.
2. The resulting metrics of the test runs are stored in a time series
database (Graphite) or appended to CSV files.
3. Otava is launched by a Jenkins/Cron job (or an operator) to analyze the
recorded metrics regularly.
4. Otava notifies about significant changes in recorded metrics by
outputting text reports or sending Slack notifications.
5. 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.
### Three most important unfinished issues to address before graduating:
1. Establish frequent releases as a routine, repeatable process
2. Improve documentation to lower the entry barrier for users and
contributors.
3. Define and document the desired long-term architecture. The goals of
the long-term architecture are:
a. Modularity: Keep the core library lightweight while making external
dependencies (data sources and notification channels) pluggable.
b. API stabilization: Clearly define and stabilize public interfaces
prior to a 1.0.0 release.
### 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?
The community added one new committer and a PMC member, who contributeda a
rewrite of the core changepoint detection algorithm and authored an
introductory doc on changepoint detection theory in Otava.
Since the last report, there have been 4 additional contributors
participated through patches and discussions. One contributor is a
developer from RedPanda, who reports using Otava extensively for both
continuous benchmarking and finding regressions in PRs. Another
contributor developed a visualization tool that allows users to model and
explore changepoint detection results across different time series. This
tool improves understanding of the algorithm’s behavior and provides a
practical aid for internal development and experimentation.
Additionally, open-source projects that position performance as a key
feature (e.g.,
[hardwood](https://github.com/hardwood-hq/hardwood/issues/25)) have
expressed interest in using Otava for continuous benchmarking.
### How has the project developed since the last report?
The project addressed 3 out of 4 main previously stated priorities:
1. Upgraded to supported Python versions. Re-implement the core changepoint
detection algorithm and drop the dependency on signal-processing-algorithms.
2. Added a new PPMC member.
3. Publicity around the project. Since the last report, Henrik Ingo did a
talk about Continuous Performance Engineering at FOSDEM 2026.
The remaining issue is making frequent releases a routine. As a first step,
the project added a step-by-step release guide to facilitate repeatable
releases.

### Three most important unfinished issues to address before graduating:
1. Making a release
2. Adding contributors
3. Finish infrastructure migration (currently working on the website)
### Are there any issues that the IPMC or ASF Board need to be aware of?
After delays last year and the promise to keep project momentum up, this
has been the case.
### How has the community developed since the last report?
- We have added a new committer and PPMC member.
- Work continues on a first release
### How has the project developed since the last report?
We have migrated our website tech to a more modern platform that can
