Incubator PMC report for December 2021

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

In recent time some of the incubator reports has been late and board members have not had adequate time to review to improve this situation:

Report generation tools have been updated to be able to produce future report templates
One full year (2022) of report templates have been produced
The dates due for all of 2022 Incubator reports have been published
ISC calendar files have been produced for all of these dates in 2022

Podlings that failed to report, expected next month

Three most important unfinished issues to address before graduating:

Make more releases
Complete Maturity assessment
Prepare graduation process

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

There are no issues right now.

How has the community developed since the last report?

Multiple of the contributors that we mentioned in the previous report were elected as committers
We've seen increased discussions on the dev mailing list (159 mails in October, 97 mails in November) and have many fruitful discussions
We received an increased amount of bug reports and questions from users, which shows increased adoption
We've seen a few applied research papers where StreamPipes was used as a basis for digital twin management
An article about StreamPipes in the US Linux magazine which was published in March is now also available online: https://www.linuxpromagazine.com/Issues/2021/244/Apache-StreamPipes/(language)/eng-US
Community members held two talks in the ApacheCon IoT track
Number of Twitter followers has increased (last report: 199, currently: 208)
Number of Github stars increased (last report: 255, currently: 274)

How has the project developed since the last report?

During the reporting period multiple large improvements were developed by the community
- A completely renewed data explorer to visualise historic time-series data
- Advanced user and role management to handle multiple users and define individual data access
- A new stateless authentication system
- A testing framework for e2e tests to continually improve the software quality
The community decided to merge the three repositories (incubator-streampipes, incubator-streampipes-extensions, and incubator-streampipes-installer) into one to ease the release process which had previously three release artifacts
Currently preparations for the next release 0.69.0 are performed and we are slowly but steadily nearing towards a 1.0 release

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:

Make sure that every PPMC is able to manage a release
Release the first version of Apache Wayang under the umbrella of the Apache Software Foundation
We have significant growth (stars / forks at GitHub), but we want to gain more popularity and growth the community further

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

Apache Wayang is doing the first release, and it has many iterations; almost all the -1 votes comes from license issues or related. Many members of the community comment about the lack of documentation and examples in the incubator page in a case like:

set up well the license when you bring pieces of code from another project.
what happens when you bring code from another source.
How need to be the headers if you bring the code from the repository that it said is apache but does not contain headers licenses.
How to need to be the license when you bring a code snippet or similar.
and some another cornet cases that could happen.

How has the community developed since the last report?

The community growth is significant (according to Github), the team around Apache Wayang was present at the BOSS conference ’21 and the Apache @home conference. We also signed an LOI with the TU of Berlin to cooperate with “AGORA-EO: Indexing and Querying Earth from Federated Big Data Archives”. The TU Berlin will add federated image processing to Apache Wayang.

How has the project developed since the last report?

As we had to import and rebrand a running project we needed some time to rework the code base for fitting the ASF standards, which resulted in 8 release candidates. The incubator community spottet the issues we weren’t aware of, which allows us now to present the first release of Apache Wayang without a WIP disclaimer. We have chosen this route to make sure that the project will always fit the standards, even when we had different views. At the end all concerns and issues were solved, thanks to the Sheppards.

Technology wise the Podling is a productive state, which is also reflected by cooperating with the TU Berlin. We see growing adaption in the market, especially from companies with large data processing pipelines.
