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), 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:

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.

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?

In our previous report we already shared our successfully completing the first release as an Apache Incubator process. This first release was mostly focused on a) bringing together various github forks under the a unified ASF upstream project, and b) releasing one release with the new project name, and following the ASF process, but one that did not in itself contain a lot of new features or changes beyond (a).

With such an inaugural release out of the way, we have seen over the past 4 months a handful of patches that make more substantive changes to the codebase. We still have a couple foundational tasks remaining that are holding us back from accepting new code contributors and contributions without any friction, but the door is at least more open than it was before the July release (0.6.1).

The remaining foundational tasks are:

Doing another release, 0.7.x, that is still focused on backward compatibility with our past, and merely introduces small fixes in the functionality itself, as well as the release process. Re-rehearsing the actions related to releasing, and related collaboration among the project committers seems a significant part of the process of becoming a fully graduated ASF project.
Cutting the dependency on an external implementation of the "E-Divisive means" algorithm, which is the very heart of what Otava does. This is the so called "signal-processing-algorithms" pip module released by MongoDB under the Apache 2.0 License, but not donated to ASF. We have come to the conclusion we need this very core functionality to be part of our own code base and version control, and since we didn't manage to get the MongoDB team's attention, we decided to rewrite an independent implementation.
Upgrading from the unsupported python versions 3.8 and 3.9 to the most recent versions.

1 above is already undergoing voting, and 2 is in review and approved, waiting to be merged.

The 0.7.x release also brings back an additional distribution format: docker images.

For the rewrite of the E-Divisive algorithm we are glad to report we found a completely new contributor to the project, with sufficient mathematical education to take on this somewhat daunting task. In the process of re-implementing the algorithm directly from its academic publication, the contributor managed to discover a bug/omission in the implementation we have been using for almost a decade now. The effect of this discovery is that the new implementation will find change points that the original algorithm tends to miss, in situations where there are 2 or more changes close to each other.

The fact that the new implementation of the E-divisive algorithm was done by a completely new contributor, that did not look at the MongoDB implementation before creating the new implementation, means that our new implementation ought to qualify as a properly independent, clean room implementation. While this was not a strict requirement for this task, now that this is the outcome, we wish to record it in the board minutes.

Altogether we have during our first year as an ASF incubator now received code contributions from 3 founding project members and 3 new contributors and one of the project mentors. In addition to these 7 there have been several more that contributed either a bug report or participated in an email thread, or voting for a release. One of these was a developer from the Tarantool open source database, that started using Otava as part of their Continuous Benchmarking. As discussed in this update, we believe there are more interested contributors that are still held back by our old python version and untangling a major legacy dependency.

We have not yet approved new committers or PPMC members to the project, as there was not yet sufficient time and opportunity to demonstrate significant and sustained contributions to the project. We are optimistic that we are moving in the right direction where this could be happening in a near future.

On the topic of committers and PPMC members it is notable that several of the past contributors that were listed in our project proposal a year ago, and approved as founding PPMC members, have not actually shown up on the ASF mailing list during our first year. We will follow up with these individuals to confirm their desired status with the project, and take appropriate action based on that outreach. (From a community diversity and robustness perspective, it should be mentioned that the 3 founding contributors that have been the most active, still represent 3 different employers, and to the best of our knowledge, the new contributors are also employed by 3 net new employers.)

How has the project developed since the last report?

(See above, it felt meaningful to combine these two answers.)

VP, Brand approved the new project name in February. Our life as an ASF incubating project really only started after that date.

We are not aware of any trademark issues related to the new project name.
