VXQuery

What the board has decided about this committee or office, and the reports it filed, most recent first. Generated from the published minutes.

These categorised views are best effort. They are read from the published minutes by a program, and what it can attribute to a committee depends on how each resolution happens to be worded — so a page may be incomplete, and nothing here overrides the minutes themselves. The raw minutes are the source of truth.

Please note. The board approves the minutes of a meeting at the meeting after it, and they are published then - so the most recent meeting is not usually here. ASF Members can read the draft in the board's own repository until it is.

incubator release before graduation to
a) release the changes that accumulated while the first release was
 prepared and to
b) have a release prepared by another RM.

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

No.

VXQuery has been incubating since 2009-07-06.

The most important issue to address in the move towards graduation is still
the first release. Two release candidates have been created and rejected so
far. The third release candiate is not ready yet.

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

It would be great to have more active mentors.

How has the community developed since the last report?

Steven Jacobs has started to contribute to the project as part of his GSoC
project of integrating Lucene indices into VXQuery.

How has the project developed since the last report?

Work on a benchmark to evaluate the performance and applicability of a
parallel XQuery engine has been started. This has triggered further progress
on the rewriting of queries to increase the level of parallelism for some
classes of queries.

first release. The release preparations had started before the October
report, but they were not completed as the release manager was not able
to work on the release artifacts during November and December.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
There currently is only one active mentor (Jochen), which could be a
problem for the release vote.

How has the community developed since the last report?
no changes

How has the project developed since the last report?
There has been progress on the creation and execution of parallel plans
for XQueries and some issues around the creation of release artifact have
been resolved.

The VXQuery Project implements a standard compliant XML Query
processor for parallel evaluation.
It has been in incubation since 2009-07-06.

VXQuery was able to maintain the increased level of activity that was
reported in the July report and made significant progress towards completing
the XQuery functionality.

The remaining top issue is a release. Recently the preparations for the
first release have started and they are still ongoing. Release artifacts
should be available and voted on in the next few weeks.

The VXQuery Project implements a standard compliant XML Query
processor for parallel evaluation.
It has been in incubation since 2009-07-06.

VXQuery changed its focus from being a pure library implementation
of XQuery in Java to being an engine for parallel XQuery evaluation.
For the runtime VXQuery now leverages the Hyracks system which is
an Apache-licensed parallel execution engine developed at UCI.

So far the top issues were

  1) low activity
  2) small community
  3) create a release.

The activities on these issues are:

  ad 1)
  Since this change of focus - and the start of a GSoC project with
  this new focus - development activity has picked up significantly.
  This due to both activity of the GSoC student (Preston Carman) and
  of the existing committers.

  ad 2)
  Preston Carman a) has provided good patches for VXQuery and
  b) interacts very well with the existing community.
  Consequently he is a candidate to be the next committer for VXQuery.
  After the initial vote on vxquery-private failed (all committers
  voted +1, but there was no mentor/IPMC member vote), Jukka Zitting
  voted +1. The next step is to finalize the administrative part to
  make Preston a committer.

  Further, there is a plan to publish a  paper to show the projects
  utility and to increase the visibility of the incubation effort.

  ad 3)
  After the change of focus some things work, but not enough to
  build a release that is easily consumable. VXQuery should be
  released before a paper is published to enable readers or the
  paper to run the software.

The VXQuery Project implements a standard compliant XML Query processor.
It has been in incubation since 2009-07-06.

Recent activities:

  - change of the focus of the project (the previous focus was to be
    flexible wrt the representation of the data model, the new focus
    is parallel processing of large amounts of XML data)
  - renewed development activity
  - 2 proposals for GSoC (1 person expressed interest in working on
    VXQuery for GSoC)

Top issues before graduation:

  - Build community

    VXQuery's community is still the initial (very small) community
    The goal of the change of focus to attract more interest in the
    project and to increase the size and diversity of the community

  - Create a release

[September report follows]

The flood of Hadoop related projects continues with new Incubator projects:

* HMS (now Ambari), a monitoring, administration and lifecycle management
project for Apache Hadoop clusters
* Accumulo, a sorted, distributed key/value store based on Google's
BigTable design, and built on top of Hadoop, Zookeeper, and Thrift

were voted to start Incubation, along with:

* Kalumet, a complete environment manager and deployer including J2EE
environments (application servers, applications, etc), softwares, and
resources.

Other projects under discussion:

* S4 (Simple Scalable Streaming System), a general-purpose, distributed,
scalable, partially fault-tolerant, pluggable platform that allows
programmers to easily develop applications for processing continuous,
unbounded streams of data.

OGNL should be moving to Apache Commons.


Ambari (was HMS)

Ambari is monitoring, administration and lifecycle management project for
Apache Hadoop clusters.

* Incubating since 30 August 2011.
* Changed name to Ambari over trademark concerns.
