AsterixDB

Apache AsterixDB is a scalable big data management system (BDMS) that
provides storage, management, and query capabilities for large collections
of semi-structured data.

AsterixDB has been incubating since 2015-02-28.

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

  1. Migrate issues from Google Code
  2. Do an Apache release.
  3. Grow community

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

  1. The most urgent issue right now is to migrate the issues from the
     Google Code tracker to the ASF JIRA (INFRA-9954) as Google Code turns
     read-only on Aug 24. The issue was open with sporadic activity for
     some time. Recently, the frequency of the interactions with infra has
     increased significantly (thanks!), but the problem is not solved yet.
  2. There was a discussion on the use of a Gerrit instance hosted at UCI
     for code reviews in this project. After an initial assumption that this
     was contrary to Apache policy and the subsequent
     a) clarification on how Gerrit is being used (every AsterixDB commit is
        explicitly made by a committer to the ASF git repo - not by Gerrit),
     b) configuration of Gerrit that all notifications are sent the the
        project's mailing list, and
     c) addition of a step at Gerrit account creation that requires that an
        ICLA is on file at the ASF
     the current state of the discussion is that this is
     a) not contrary to policy but also
     b) not ideal as the regular workflow depends on non-ASF resources.
     Ideally the code review tool would be hosted by infra, but capacity is
     an issue.

    Did not report (3rd time in a row). Low mailing list activity.

--------------------
Blur

Blur is a search platform capable of searching massive amounts of data
in a cloud computing environment.

Blur has been incubating since 2012-07-24.

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

  1.  At this point we need to have more releases, more often.
  2.
  3.

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?

  - Subscriptions: user@ - 55[-2]; dev@ - 67[0]

How has the project developed since the last report?

  Many bug fixes, plus a release vote was called.  It did not pass due to
  some licensing issues with a javascript library in a web application that
  is apart of the Blur project.  It has recently been resolved, we will call
  a vote for a new release in the beginning of August.

Date of last release:

  2014-07-29 (The vote for the 0.2.4 release was called on 2015-07-02)

Calcite

Calcite is a highly customizable engine for parsing and planning queries on
data in a wide variety of formats. It allows database-like access, and in
particular a SQL interface and advanced query optimization, for data not
residing in a traditional database. (Renamed from Optiq on 2014-09-30.)

Calcite has been incubating since 2014-05-19.

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

  1. Add more PPMC members.
  2. Demonstrate community robustness by rotating project tasks among
     multiple project members.
  3. There is no third thing. We are almost ready to graduate.

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 last report was in April. (We are reporting a month late, because
  we missed the July report.)

  In July, there were 148 messages on dev@, 37 commits, 44 issues
  created, 39 issues resolved by 10 contributors.

  Diversity is improving. The 1.4 release will be the first release for
  which Julian Hyde was not release manager.

  Julian Hyde won best lightning talk at XLDB 2015 in May with the talk
  "Apache Calcite: One planner fits all".

  Tom Barber spoke about Calcite at ApacheCon NA in April.

  Collaborations with other Apache projects continue:

  * Phoenix has built a remote JDBC driver using Calcite’s Avatica
    component.
  * Phoenix is replacing their SQL parser & planner with Calcite.
  * Samza is developing support for streaming SQL queries using
    Calcite for parsing and planning.
  * Kylin upgraded from 0.9.2 to 1.3.
  * Collaboration with Hive and Drill continues.

How has the project developed since the last report?

  We completed releases 1.2 and 1.3, and are preparing 1.4.

Date of last release:

  2015-05-30 apache-calcite-1.3.0-incubating

When were the last committers or PMC members elected?

  2015-04-24 5 new committers

Shepherd/Mentor notes:

  Ted Dunning:

    This is turning into a serious community. They should consider
    graduation.


  johndament:
    Podling seems to be in good shape.  They may want to consider
    beginning the graduation process.

Climate Model Diagnostic Analyzer

CMDA provides web services for multi-aspect physics-based and phenomenon-
oriented climate model performance evaluation and diagnosis through the
comprehensive and synergistic use of multiple observational data, reanalysis
data, and model outputs.

Climate Model Diagnostic Analyzer has been incubating since 2015-05-08.

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

  1. Start developing at the ASF
  2. Start using ASF JIRA
  3. Get code pushed to ASF Git repo

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

  N/A

How has the community developed since the last report?

  See below

How has the project developed since the last report?

  CMDA has not really gotten started at the ASF yet. Very little has changed
  since the last report. The most important thing is getting the community
  started. At the moment the CMDA JIRA is completely empty and the code base
  has yet to be pushed to the git repo. Mailing list activity is largely
  non-existent and there's no website up for the project yet. Hopefully
  these hurdles will be crossed during this next month so that more active
  develop can start for the project.

--------------------
DataFu

DataFu provides a collection of Hadoop MapReduce jobs and functions in
higher level languages based on it to perform data analysis. It provides
functions for common statistics tasks (e.g. quantiles, sampling), PageRank,
stream sessionization, and set and bag operations. DataFu also provides
Hadoop jobs for incremental data processing in MapReduce.

DataFu has been incubating since 2014-01-05.

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

  1. Do first release
  2. Grow user and contributor base
  3. Increased committer activity

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

  * Performing the initial release remains the most important milestone.
    However, the majority of the known tasks for this have been completed.
    The remaining tasks are related to documentation.  We are able to
    generate a signed, versioned source release from the build system.

How has the community developed since the last report?

  * A couple new contributors have submitted patches.  One of these has been
    committed and the other is nearly ready to be committed.

How has the project developed since the last report?

  * The build system has been updated to provide tasks for generating
    signed, versioned source releases.  Documentation has been updated as
    well with instructions on how to do this.
  * Apache DataFu has been updated to run against Hadoop 2.  There was an
    issue running the Hourglass integration tests against Hadoop 2, which
    had been blocking this update.
  * A couple new patches from two new contributors for Pig UDFs have been
    submitted.  One of these is an improvement to the HyperLogLog UDF
    cardinality estimator that makes it much more efficient.  The other is a
    helper for getting a tuple out of a bag.
  * A patch has been submitted for a UDF to incrementally process
    date-partitioned data in Pig.  This provides similar functionality that
    is available in Hourglass.

Date of last release:

  * Not yet released

When were the last committers or PMC members elected?

  * November 2014

Shepherd/Mentor notes:

  Ted Dunning: 
  
    The generation of signed releases on shared hardware has historically
    raised serious security questions from infra. I think that this process
    needs to be vetted very carefully.

--------------------
Droids

Droids aims to be an intelligent standalone robot framework that allows to
create and extend existing droids (robots).

Droids has been incubating since 2008-10-09.

Shepherd/Mentor notes:

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

  1. IP clearance
  2. Move to ASF infrastructure, especially the code repository
  3. Finding 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?

  We are in early stage of incubation (like source code wasn't imported
  yet), so there's no change.

How has the project developed since the last report?

  We have collected the required Software Grants and ICLA-s. We are working
  on the migration to the ASF infrastructure and preparing for the IP
  clearance process.

Date of last release:

Tamaya

Tamaya is a highly flexible configuration solution based on an modular,
extensible and injectable key/value based design, which should provide a
minimal but extendible modern and functional API leveraging SE, ME and EE
environments.

Tamaya has been incubating since 2014-11-14.

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

  1. We need more active contributors.
  2. We ​must ​provide support for Java EE​.​
  3. We ​must release more often.

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?
  Streamlining all features and preparingthe first release took more
​  ​time as​ originally suggested due to absences of​ key people involved.
​  ​It has shown that​ additional committers are urgently needed.
  There were several ​that have shown interest,​ but unfortunately this
​  ​did not lead to​ ​additional contributors.

  We hope that presentations at ApacheCon,​ ​Devoxx and several other
​  ​conferences as​ well as articles at JAXenter and more will
​  ​help to improve the community until end of​ ​year.

How has the project developed since the last report?
  We have now an agreed core set of APIs and ​extensions that provide a
  healthy and usefule base for the future. The extensions are all
​  well tested​ and documented​, so we should be able tome come up
​  if a good quality with our first release. The first release
  0.1-incubating is now in the vote on PMC, so we are
  now on track to further wider community awereness for our
  project. Anatole has a article series on the topic in the
  biggest​ German technical paper and also will blog regularly
​  on it, once the release is out. As a star spec lead his
  network should definitively help to grow community then.​

Date of last release:

  None. But first release is discussed in the PMC as of now​,
  so within the next 1-2 week it should be out​.

When were the last committers or PMC members elected?
