# 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.

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 
presently 38 podlings incubating. In November, podlings executed 7 distinct 
releases. We added two new IPMC members, and none retired.
There was one IP clearance. A couple of new podlings are under discussion, 
and SeaTurltleSeaTurtle has joined the Incubator. There where no graduations last 
month.

A couple of podlings are heading towards graduation in the next few months. 
This month we were missing reports from Hivemall, Livy, PageSpeed, SDAP, 
Spot and Training, and they will be asked to report next month. All 
podlings mentioned have had a history of misisng the occasional report, and 
most have low levels of activity. Training is discussing possible 
retirement. Spot has very low activity levels and has missed multiple 
reports. Spots last roll call only attracted 2 PPMC members.  I've 
requested another roll call and asked them if it is time to consider 
retirement.

Multiple projects were asked to use the correct URL for their KEYS files. 
A few projects have been using the WIP disclaimer a little too widely, and 
their release votes attracted -1 values.
We usually had a top level project ask for a vote on their release and were 
unable to help them.

In recent time some of the incubator reports have been submitted 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

As usual, most discussions on the mailing list were around graduations, 
releases, and new project proposals.

### 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/(languag
  e)/eng-US
  * Community members held two talks in the ApacheCon IoT track
  * Number of Twitter followers has increased (last report: 199, currently: 
  208)

### 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

## Toree

Toree provides applications with a mechanism to interactively and remotely
access Apache Spark.

Toree has been incubating since 2015-12-02.

### Three most important unfinished issues to address before graduating:

  1.Increase active contributors
  2.
  3.

### 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?

  Not much, the community has been trying to vote a release without much 
  success.
  I am starting to think that maybe the best solution might be to try to 
  reboot
  the podling and see if we can inject more new blood to the project and 
  see if
  it could make a change. I will think more about this and propose something
  for the next report.

### How has the project developed since the last report?

  Very minimum discussions towards the release vote.

### IPMC/Shepherd notes:

--------------------
## 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. Make sure that every PPMC is able to manage a release
  2. Release the first version of Apache Wayang under the umbrella of the 
  Apache Software Foundation
  3. 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.

### Date of last release:  

  No Release yet. At the moment of this report, the RC9 is under votes.

### When were the last committers or PPMC members elected?
