AriaTosca

ARIA TOSCA project offers an easily consumable Software Development Kit(SDK)
and a Command Line Interface(CLI) to implement TOSCA(Topology and
Orchestration Specification of Cloud Applications) based solutions.

AriaTosca has been incubating since 2016-08-27.

Three most important issues to address in the move towards graduation:

  1. Grow the community and enroll new committers.
  2. Have (more) frequent Release cycles to be compliant with the Apache Way.
  3. Grow the project’s contributions from existing community of contributors

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?

1. The project issued its third release (0.2.0) as far as the code is
   concerned.  Some considerable functionality has been added since the last
   release in addition to a growth in diversity of contributions.

How has the community developed since the last report?

* All project communication now takes place on either the mailing list or
  ASF's Slack, and is open for everybody.  We have worked hard to make this
  the normal operating mode of the community. There have been some hiccups,
  but in general the majority of discourse has taken place on the list.

 * Increased chatter on the mailing list including new subscribers who ask
   questions, make suggestions and are likely to become contributors
   themselves in the near future.

* Weekly grooming meetings are now attended by the majority of the community.
  This is not only a forum to review the weekly work items list, but also as a
  place for open discussion about issues, questions as well as for the
  community to get to better know each other.


How has the community developed since the last report?

Over the last 3 months we have seen a significant increase in contributions as
well as a few new contributors, particularly from the Ericsson contingent.


How has the project developed since the last report?

ARIA now has two new patches considerably extend the parser's
plugin/extensions

Website and documentation improvements for usability and to enhance new user
Usability in terms of “getting started” instructions

9 JIRA issues have been resolved since the last report.  Note that the
repository was locked for several weeks during this period due to release
process issues and learning curve.

We will be doing another release during this quarter.

The community has begun to undertake updating AriaTosca to support the Tosca
1.1 Simple YAML profile.

Daffodil

Apache Daffodil is an implementation of the Data Format Description Language
(DFDL) used to convert between fixed format data and XML/JSON.

Daffodil has been incubating since 2017-08-27.

Three most important issues to address in the move towards graduation:

  1. Complete first Apache release as an Incubator
  2. Broaden base of contributors and build the community (e.g. work with
  other Apache projects where Daffodil could provide extra functionality)
  3. Improve documentation on setting up a development environment to ease the
  addition of new developers

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?

- Outstanding legal issue regarding Open Grid Forum document inclusion in
  Daffodil (LEGAL-369)

How has the community developed since the last report?

- No new committers. However, we have had activity from a couple outside users
  on the mailing lists asking about Daffodil capabilities/usage

How has the project developed since the last report?

- All SGA/CLAs have been submitted (from Tresys, IBM, and NCSA), all code
  relicensed to ASF, and package namespace switched to org.apache.daffodil
- Development pace has continued without any notable issues
- The first release candidate was created in February 2018. However, bugs were
  found that required an rc2 release. Those issues were resolved, but issues
  related to the LICENSE and NOTICE files were raised in the rc2 release vote.
  This is expected to require an rc3 release, planned to start voting in early
  March.

Druid

Druid is a high-performance, column-oriented, distributed data store.

Druid has been incubating since 2018-02-28.

Three most important issues to address in the move towards graduation:
 1. Migrate existing contributors and users to apache mailing lists.
 2. Move the source code and website to apache infrastructure.
 3. Plan and execute our first Apache release.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?
* The team is working on the items on the Incubation Checklist.
* We’re working on moving the existing mailing lists, source code, github
  issues and website to Apache Infrastructure.
* In order to keep the project momentum up until the migration is complete we
  are continuing the development on existing druid repository.
* We are considering doing the 0.12.0 release before migrating source code to
  apache, since the IPMC has already voted for it and migrating infra to
  apache might take a while, and we don't want to block 0.12.0 on this
  migration.

How has the community developed since the last report?
* This is our first board report.
* Current Status of our Github contributors (212), forks (1,516), watchers
 (524) and stars (6,157)

How has the project developed since the last report?
* Creation of Domain name for Druid - DONE
* Creation of Mailing lists - DONE.
* A healthy, constant flow of bug fixes, quality improvements and new
  Features are still ongoing on https://github.com/druid-io/druid.

Myriad

Myriad enables co-existence of Apache Hadoop YARN and Apache Mesos together on
the same cluster and allows dynamic resource allocations across both Hadoop
and other applications running on the same physical data center
infrastructure.

Myriad has been incubating since 2015-03-01.

Three most important issues to address in the move towards graduation:
In this project state the most important action to move towards
graduation is to create traction on the project again. So from my
point of view the list of actions is the following:

[X] Promote the project in social networks, blog entries and so forth
for getting interest again.
[X] Get a few active new users.
[X] Refresh the state of unattended issues reported for interested
users in the pass.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
Only to be informed about new users are willing to boosting up the
project again.

How has the community developed since the last report
The most relevant thing is the activation of mailing list again and a
few new users willing to participate.

How has the project developed since the last report.
The project has not evolved since the last report.

How does the podling rate their own maturity.

OpenWhisk  

OpenWhisk is an open source, distributed Serverless computing platform able to
execute application logic (Actions) in response to events (Triggers) from
external sources (Feeds) or HTTP requests governed by conditional logic
(Rules). It provides a programming environment supported by a REST API-based
Command Line Interface (CLI) along with tooling to support packaging and
catalog services.  Additionally, it now provides options to host the platform
components as Docker containers on various Container Frameworks such as Mesos,
Kubernetes, and Compose.

 
OpenWhisk has been incubating since 2016-11-23.

Three most important issues to address in the move towards graduation:

  Establish process for source release (automation work ongoing here
  https://github.com/apache/incubator-openwhisk-release) Increase contributions
  to maintain all project repos. Kubernetes and Mesos deployments work and 
  integrations need improvement; comm, aware of lots of work being done in 
  (private and public) forks.

  Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
  of?

  - Issue backlog building on incubator-openwhisk has grown significantly;
    need to prioritize and work to reduce while advancing
    performance/security/deployment issues.
     - Trying to add more active Committers to augment those who have
      dropped off in their activity. A consistent hosted, staging
      environment would help repro. issues, as well as stage PRs to test
      fixes. It had been our intent to have Apache host our staging (and
      move it out of disparate private builds within various companies).
      However, INFRA indicates they only typically allocate 1 VM per
      project for use with demos and minor things.  They indicate that
      perhaps a corporate donation is in order (ala. Spark).
     - Goal: standup testing resources at Apache and utilize for public CI
      and performance testing of OpenWhisk on Kubernetes
     - See discussion here: OpenWhisk / Kubernetes proposed epics/action
      items/questions
     - No change in status since last quarterly report
  - Formal hand-off of OpenWhisk trademark/logo from IBM needs to be
    executed; need to identify process for this.
     - Discussion started w/ Apache legal via "legal-discuss" mailing list
      with subject "Trademark handoff for "OpenWhisk" name and logo".
     - No change in status since last quarterly report

How has the community developed since the last report?

  Mentor changes:
     - Felix Meschberger and Sergio Fernández have stepped down from being
      mentors with regrets.
     - Bertrand Delacretaz volunteered to become mentor to fill Felix' spot.
     - Jim Jagielski volunteered to become mentor to fill Sergio's spot.
  - dev mailing list usage has been relatively active
  - incubator-openwhisk Github stars: 2877 (+696 since last report)
  - incubator-openwhisk GitHub forks: 544 (+75 since last report)

How has the project developed since the last report?

  Emphasis on 3 areas have been featured since last report:
  - Release process
     - See incubator-openwhisk-release (code, tools, documentation), see
      demo (as of 2/28): YouTube
        - Lots of discussion and work on developing both a manual and
         automated (source code) release process for 12 openwhisk project
         repos. that constitute the project's platform and related tooling
         (i.e., version tied).
        - All steps in release process are described in repo's markdown
         that the comm. is working to complete
        - Checklists/Runbooks created for release managers to follow
        - Automation tested with signing/hashing as per Apache requirements
        - still working on assuring all Apache license/legal/notice/change
         files are present (perhaps automated as well) issues with RAT and
         TENTACLES tools documented, working to document our exception
         lists and policies and alternative tools to verify licenses when
         not supported by RAT
  - Security enhancements
     - Now encrypting "data-in-motion" by enabling SSL between Controllers,
      Kafka and Invokers.
  - Scalability / Performance
     - Controller now uses fully scalable impl. instead of active with "hot
      standby"; lots of testing/changes to validate as optional before
      moving to promote as default on dev. list.
     - Introduced new LoadBalancer plug-in that uses Horizontal sharding;
      evaluating making it the default as perf. tests indicate notable
      improvement in controller-invoker throughput under load.
     - Improved handling of Artifact Attachments as a separate artifact (for
      storage/update/deletion) and provide alternative implementations
      (other than CouchDB), primarily Object Storage services as targets.
     - Made ActivationId implementation leaner by adopting UUID (single
      string) versus an object that wraps a UUID.
  - Other Notable discussions/changes/issues/features:
     - Added support of Time-series DBs using Kamon Tag (e.g., OpenTSDB,
      Datadog)
     - Discussions on large (size) argument support in runtimes/impacts on
      performance/configurability.
     - Updated all tools/ubuntu-setup to support xenial and later Ubuntu
      releases.
     - Implementation of runtime for Go (GoLang) actions.  New contributor
      authored new Invoker runtime and tested with 3 possible impls. for
      performance before submitting for review.
     - Action Compositions now supported in Controller and demonstrated on
      Interchange call; more changes may be coming for Controller to enable
      parallel processing.
     - Added A Pull Request (PR) template (checklist) for all code
      submissions (incubator-openwhisk) to assure they are ready for review
      and get assigned correctly.
        - https://github.com/apache/incubator-openwhisk/pull/3386

PLC4X

PLC4X is a set of libraries for communicating with industrial programmable
logic controllers (PLCs) using a variety of protocols but with a shared API.

PLC4X has been incubating since 2017-12-18.
Three most important issues to address in the move towards graduation:

  1. Building the community: The PPMC and committer group has a large
     percentage of codecentric employees, we have been recruiting people
     from other companies, but will have to continue these efforts for
     establishing a healthy Apache community.
  2. Onboarding of new committers: With PLC4X several people on the team
     are not very familiar with the Apache Way. We have started and will
     continue our efforts on this onboarding.
  3. Make our first release

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

In order to get access to some of the specifications the ASF will eventually
have to become Members of some external foundations: OPC, EtherCat, Modbus …
these memberships usually have a free level, that allows us to use the
specifications but doesn’t result in any regular costs. We will have to discuss
these details with the ASF and the other foundations.
One of the external foundations (Profinet) doesn’t have a free membership. In
general, the CEO of the European branch of the Profinet Foundation has signaled
that it should be possible for the ASF to become a member and have an outside
company pay the membership fees, but we have to discuss the details (With them
as well as the ASF).

How has the community developed since the last report?

Christofer has invested most of his time in February spreading the word about
PLC4X.
A first POC has been created for the company “Kampf Schneid- und Wickeltechnik
GmbH & Co. KG”
Two articles for IoT Special editions of German tech magazines have been
submitted. The “JavaSPEKTURM – IoT Sonderheft” is scheduled for sale end or
March, the “iX – IoT Sonderheft” is scheduled later.
The university of Stuttgart has shown great interest in joining our effort, as
they had just started a project with a similar goal. Chris will continue
on-boarding efforts in March.
At this year’s AALE Conference in Cologne, Chris has talked to a lot of people
from different German universities. We’re hoping to get at least a hand full of
them on board too.
We have continuing our onboarding of new Apache committers (extended emails
with a lot of explanations on why we are doing things the way we are)
In the next few months we are expecting to spread the word and hopefully grow
the community due to the tech magazine articles as well as several talks on
different conferences.

How has the project developed since the last report?

The work on the RawSocket Netty transport which is a requirement to implement
protocols that are IP based, but are not TCP or UDP has continued and we are
currently waiting for infra to setup a dedicated Jenkins VM for our project so
we can enable the RawSocket releated tests.
We have finished a first version of the Beckhoff ADS driver, and are looking
forward to first tests with this.
The functionality of the S7 driver has improved due to experience collected
with the Kampf POC.
Next we are aiming to implement Modbus and OPC-UA protocols.

How would you assess the podling's maturity?
Please feel free to add your own commentary.

We have a mix of new participants and experienced Apache people involved.
So far, the new participants have shown great willingness and success in
adopting the Apache Way.
However, we still need to continue:
the on-boarding
increasing the diversity of the team
Also, will we need to decide and establish all the processes involved in
releasing software at Apache

  2. Complete the Podling name search tasks

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?

  None

How has the community developed since the last report?

  The community added 6 new contributors that submitted pull-requests which
  were merged into master.

  There has been a sharp increase in users approaching the team on the Slack
  channel with many questions on getting started, clarifications,
  troubleshooting. While developers use Slack for informal chatting, the
  predominant usage of Slack has be users support. We have created a tool to
  create daily email digests of the conversation and post it on dev@ and user@
  lists, to comply with ASF policy of. We are also extracting the most
  recurrent questions/answer from Slack and plan to add an FAQ section on the
  website, together with improving documentation in the areas that seemed more
  difficult to users.

  Project members from several companies have organized or participated in
  several meetups, presenting Pulsar's introductions, deep-dives and hands-on
  tutorial, including recorded podcasts. We have several scheduled talks on
  Pulsar at various conferences (such as Strata San Jose on March 8th).


How has the project developed since the last report?

  22 authors have pushed 536 commits to master in the last 3 months.

  The project has made the its third and fourth releases since joining the
  Apache Incubator (1.21.0-incubating on Dec 17th and 1.22.0-incubating on Mar
  6th). Project members are actively working on next milestone, 2.0 release
  that will include several new features including:
   * Topic compaction
   * Redesigned type-safe API with schema support
   * Lightweight compute support

  Overall, since December, 7 new PIPs (Pulsar Improvement Proposals) for major
  feature/changes, have been submitted to the wiki and discussed in the
  mailing list.

  Since the last report the number of weekly-active-users on the Slack channel
  has increased from 27 to 53.

Slider

Slider is a collection of tools and technologies to package, deploy, and
manage long running applications on Apache Hadoop YARN clusters.

Slider has been incubating since 2014-04-29.

Most important issues to address in the move towards graduation:
  Since new development on one of Slider's primary maven modules has
  moved to the hadoop-yarn-services-core module in Apache Hadoop,
  development of other Slider modules has also tailed off. The Slider
  community needs to decide whether we should retire the remaining
  Slider code or propose graduation.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  No additional issues.

How has the community developed since the last report?

  Mailing list and commit activity have continued at a low rate. We invited
  a new committer / PPMC member, Kyungwan Nam.

How has the project developed since the last report?

  An improvement to allow Slider to work in multi-homed environments is
  in progress and we have fixed a couple of bugs related to certificate
  management and functional test failures when running on newer versions
  of Hadoop.

How would you assess the podling's maturity?
The podling is relatively mature, but activity is low.

  I have been quite impressed by the uptick since New Year, which shows how just
  a bit of PMC engagement can give lots of follow-on activitity. I would hope
  Taverna can continue this move out of the "risk of retire" zone, but that
