Shepherd/Mentor notes:

  John D. Ament (johndament):

    It seems that the community posted one report, but then a mentor posted
    a largely reworded report.  No evidence of a discussion seems to have
    been done on public mailing lists for either report.

--------------------

engines.

Concerted has been incubating since 2015-10-14.

Shepherd/Mentor notes:

  Julian Hyde (jhyde):

    No report, despite prodding from Chris, and no activity on lists.
    I think this one's dead.

  Jake Farrell (jfarrell):

    No activity so far in 2016.

  Chris Nauroth (cnauroth):

    There has been no activity on the project for several months, and we

--------------------
Fineract

Fineract is an open source system for core banking as a platform.

Fineract has been incubating since 2015-12-15.

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

  1. Finalising the initial release
  2. Improve the communication around the differences between the previous
     MifosX project and the new Fineract project, especially in the MifosX
     community, website etc.
  3. With the first initial release, encourage the community to use the
     proper infastructure (mailing lists, issue tracker) for the ongoing
     collaboration within the community.
  4. Change management towards less 'key-man' dependency on previous
     tech/community leaders from MifosX, more towards community driven
     consensus.
  5. Reduce clutter on mailinglist from JIRA updates etc.

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

  On the mailinglist there have been discussions around the lack of traffic
  on it. This is part of the switchover from the current MifosX community
  and mailinglists towards the new Fineract lists. At the same time the
  recent meet-up of Mifosx and Fineract devs and people interested in it
  (see community development), has also triggered a lot of offline
  interaction.

How has the community developed since the last report?

  While activity on the mailinglist has been pretty low, we've had a great
  meet-up in Amsterdam where a nice mix of existing MifosX community members
  and a group of new interested people was present. This has boosted
  interest in Fineract.

  We have a high level of interest from new contributors throughout Africa -
  we are working to properly engage them and guide them to the correct
  collaboration channels in our Fineract community.

How has the project developed since the last report?

  Individual members of the leading partner organizations building solutions
  using the Fineract platform have begun to effectively use the Fineract
  issue tracker to communicate and track the requirements and enhancements
  they're building and contributing to Fineract. These individuals are
  setting a good example that other individuals from our partner community
  should follow.

FreeMarker

FreeMarker is a template engine, i.e. a generic tool to generate text output
based on templates. FreeMarker is implemented in Java as a class library for
programmers.

FreeMarker has been incubating since 2015-07-01.

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

  1. Finding more active contributors

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?

  There were no changes

How has the project developed since the last report?

  FreeMarker had two public releases: A Release Candidate (so that users can
  test it), and one final release. Apart from the new features and fixes, we
  have adjusted the source code and build process to follow Apache best
  practices more closely, and to be more appealing for contributors
  (switching to Java 5, fixing formatting where it didn't fit the modern
  Java conventions).

  The legal/policy issue with the web site domain (INFRA-10787) was settled,
  and we are using our historical domain again (freemarker.org) until
  graduation.

--------------------
Gearpump

Gearpump is a reactive real-time streaming engine based on the micro-service
Actor model.

Gearpump has been incubating since 2016-03-08.

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

  1. Make initial Apache branded release
  2. Initial community process definition and practice enforcement by
     following Apache policies
  3. Build the first Apache branded informative website to make Gearpump
     contributor and end-user friendly.

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

  The rights holder of the Gearpump copyright filed a CCLA including a
  Schedule B granting the Gearpump codebase to the Foundation. We are
  awaiting assistance from Infrastructure on INFRA-11435 to perform the
  import. 

How has the community developed since the last report?

  All of the initial committers/PPMC have set up with Apache accounts and
  Apache JIRA accounts. 

  Discussion among developers has started on

HAWQ

Apache HAWQ is a Hadoop native SQL query engine that combines the key
technological advantages of MPP database with the scalability and
convenience of Hadoop. HAWQ reads data from and writes data to HDFS
natively.  HAWQ delivers industry-leading performance and linear
scalability. It provides users the tools to confidently and successfully
interact with petabyte range data sets. HAWQ provides users with a complete,
standards compliant SQL interface.

HAWQ has been incubating since 2015-09-04.

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

  1. Produce our first Apache Release
  2. Expand the community, by adding new contributors and focusing on making
     sure that there's a much more robust level of conversations and
     discussions happening around roadmaps and feature development on the
     public dev mailing list
  3. Infrastructure migration: create Jenkins projects that build HAWQ
     binary, source tarballs, and run feature tests including at least
     installcheck-good tests for each commit (HAWQ-127).

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

  Everything seems to be smooth, nothing urgent at this time.

How has the community developed since the last report?

  1. One HAWQ Nest community meeting (topic: GPORCA: Query Optimization as a

HTrace

HTrace is a tracing framework intended for use with distributed systems
written in java.

HTrace has been incubating since 2014-11-11.

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

  1. Continue to grow the HTrace community
  2. Continue to explore projects integratiing HTrace
  3. Continue to develop and release stable HTrace incubating artifacts

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?

  * YCSB community are working on integrating HTrace.
  * Google Summer of Code 2016 projects for Apache HTrace are being planned.
    There are proposals such as
    * distributed tracing for s3 and other alternative Hadoop FS
    * Kudu span receiver
    * integrating HTrace into Hadoop YARN

    This podling's come pretty far.  Maybe time to graduate soon?

--------------------
Impala

Impala is a high-performance C++ and Java SQL query engine for data stored
in Apache Hadoop-based clusters.

Impala has been incubating since 2015-12-03.

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

  1. Transition of development workflows to ASF (see
     https://issues.cloudera.org/browse/IMPALA-3221)
  2. Initial release as incubating project.
  3. Community growth

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?

  There have been no additions to the committer or PMC lists since
  incubation began. We continue to see an uptick in external contributions,
  with two patches from new contributors this month. One contributor
  pleasingly reported it was "great to work closely with Impala community".

How has the project developed since the last report?

  We have put together a list of tasks required to move development of
  Impala from Cloudera's infrastructure to the ASF. Since Impala was already
  a well-established project before the Incubator proposal, there is perhaps
  more decoupling required than for more nascent projects. The list is at
  https://issues.cloudera.org/browse/IMPALA-3221, and is being actively
  worked on. Note that this doesn't cover the standard podling tasks (like
  name search, etc).

Date of last release:

  None since entering incubation.

When were the last committers or PMC members elected?

  None since entering incubation.

iota

Open source system that enables the orchestration of IoT devices.

iota has been incubating since 2016-01-20.

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

  1. Overcome current technical difficulties. You might be asking what is
     happening with Apache iota. The initial architecture that we wanted to
     upload was not as scalable as we required it to be. Rather than upload
     an architecture that we wanted to fundamentally change we have been
     developing a new backend architecture and code based that implements a
     significantly more scalable solution using Apache, Spark, Spark
     Streaming and Cassandra. We are still using Python and Django for our
     APIs and authentication (session and token based). Consequently, you
     haven’t seen any activity on the Apache iota site and repository. This
     will be changing soon. Litbit (the contributing company whose business
     runs on iota) has been working around the clock to remake the backend
     using additional Apache components that makes the solution far more
     scalable.
  2. Set up web site and import code. We will be setting up the Apache iota
     website to reflect the new architecture and uploading the initial
     source code as quickly as we can.
  3. Promote Iota to a wider user base / grow the community. We are planning
     to promoting iota at an upcoming keynote being given by Scott Noteboom
     (Litbit's CEO). In addition we will be presenting iota at Apache Con in
     May 2016. Our goal in promoting iota will be to start building a
     community that will contribute to moving iota to it’s first release as
     an Apache incubator project

Shepherd/Mentor notes:

  John D. Ament (johndament);

    Its a bit concerning to see that the project is starting off in a non-ASF
    way.  Even if the code isn't quite right for donation, may be better to
    start off writing new code in the ASF repos.

  Justin Mclean (jmclean):

    I too have concerns about why they are developing outside of the ASF.
    I've contacted them a few times with a please explain and have assurances
    that this will be fixed. I'd suggest placing the podling on monthly
    reports for a few more months. 

  Drew Farris (drew):

    2 mentors active on the mailing list this month, but little activity as
    the team has not moved development to ASF. Concur with keeping podling on
    monthly reports.

(for example, Raspberry Pis or smart phones). Working in conjunction with
centralized analytic systems, Apache Quarks provides efficient and timely
analytics across the whole IoT ecosystem: from the center to the edge.

Quarks has been incubating since 2016-02-29.

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

  1. Create and expand a diverse community of contributors and committers
     around Quarks project
  2. Create the first Apache release of Quarks
  3. Complete migration of website to host all content at Apache (javadoc is
     still on Github).

  The Quarks community is keeping dev-related conversations on the mailing
  list. Because of this, it's allowed for the participation of independent
  contributors in mailing list discussions. Although our list of independent
  contributors is small, Quarks is still very new as an Apache project and
  we aim to actively grow our list in the near future.

How has the project developed since the last report?

  * The project has successfully migrated from Github-based development to
    using the Apache git repo, Jira, and the mailing lists.

Date of last release:

  Quarks is still new, so we haven't created an Apache release as of yet.

When were the last committers or PMC members elected?

  No changes from the initial committers.

  2. Expand the "how to" document to explain the ways new contributors can
     become involved in the project, so we increase the size of the
     community.
  3. Add new committers to the project.

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

  No

How has the community developed since the last report?

   * We have a Rya "office hour" teleconference every other week. We had
     some technical difficulties with screen sharing, but we had a working
     solution for the last meeting. Users and developers can ask questions,
     receive answers, discuss ideas for future developments. The minutes are
     sent to the dev@ list.
   * We have more PRs from non-committers which are integrated into the
     repository. We expect some of these non-committers to continue to
     submit PRs and become committers.
   * There were several ideas from Rya for Google Summer of Code, and a few
     students expressed interest; one of them submitted a proposal

How has the project developed since the last report?

  * Created a quick-start VM for users to try out Rya.
  * Created a website for the project.
  * Resolved a handful of issues that users have encountered.
  * Committed features: incremental update for precomputed join indices,
    extensions to query planning to support more complex precomputed join
    indices, free text search support for MongoDB, additional Geo indexing
    for MongoDB, extensions of examples for both Accumulo and MongoDB backed
    Rya
