[VOTE] Accept Gora into the Apache Incubator
Hi Folks,
Over the past week or so we've been discussing the Gora project and bringing
it into the Apache Incubator [1]. It's time to call a VOTE thread on the
issue. Please VOTE below:
[ ] +1 Accept Gora into the Apache Incubator.
[ ] +0 Don't care.
[ ] -1 Don't accept Gora into the Apache Incubator because...
I'll leave the VOTE open for the remainder of the week (ending on 9/24).
Here's my +1 (IPMC binding).
[1] http://s.apache.org/MPw
Cheers,
Chris
P.S. The wiki text for the proposal is pasted below.
----------
Gora Proposal for Apache Incubation
Abstract
Gora is an ORM framework for column stores such as Apache HBase and Apache
Cassandra with a specific focus on Hadoop.
Proposal
Although there are various excellent ORM frameworks for relational
databases, data modeling in NoSQL data stores differ profoundly from their
relational cousins. Moreover, data-model agnostic frameworks such as JDO are
not sufficient for use cases, where one needs to use the full power of the
data models in column stores. Gora fills this gap by giving the user an
easy-to-use ORM framework with data store specific mappings and built in
Apache Hadoop support.
The overall goal for Gora is to become the standard data representation and
persistence framework for big data. The roadmap of Gora can be grouped as
follows.
* Data Persistence : Persisting objects to Column stores such as HBase,
Cassandra, Hypertable; key-value stores such as Voldermort, Redis, etc; SQL
databases, such as MySQL, HSQLDB, flat files in local file system of Hadoop
HDFS.
* Data Access : An easy to use Java-friendly common API for accessing the
data regardless of its location.
* Indexing : Persisting objects to Lucene and Solr indexes,
accessing/querying the data with Gora API.
* Analysis : Accesing the data and making analysis through adapters for
Apache Pig, Apache Hive and Cascading
* MapReduce <http://wiki.apache.org/incubator/MapReduce> support :
Out-of-the-box and extensive MapReduce
<http://wiki.apache.org/incubator/MapReduce> (Apache Hadoop) support for
data in the data store.
Background
ORM stands for Object Relation Mapping. It is a technology which abstacts
the persistency layer (mostly Relational Databases) so that plain domain
level objects can be used, without the cumbersome effort to save/load the
data to and from the database. Gora differs from current solutions in that:
* Gora is specially focussed at NoSQL data stores, but also has limited
support for SQL databases
* The main use case for Gora is to access/analyze big data using Hadoop.
* Gora uses Avro for bean definition, not byte code enhancement or
annotations
* Object-to-data store mappings are backend specific, so that full data
model can be utilized.
* Gora is simple since it ignores complex SQL mappings
* Gora will support persistence, indexing and anaysis of data, using Pig,
Lucene, Hive, etc
Rationale
ORM frameworks are nothing new. But with the explosion of data generated in
Terabytes and even Petabytes, NoSQL data stores are gaining ever-increasing
popularity. Coupled with limited support to already-proven Apache Hadoop
support in current ORM frameworks, there was a need for a new project.
Gora is currently hosted at Github. However, Gora has ties to ASF in many
ways. As detailed in the proposal section, Gora will be a high level client
for many Apache projects and subprojects including Hadoop(common, hdfs, and
mapreduce), HBase, Cassandra, Avro, Lucene, Solr, Pig, and Hive. Gora
already uses Hadoop, HBase, Cassandra and Avro. Moreover, Gora started its
life inside Apache Nutch project, and now Nutch trunk uses Gora as a
library. Even more, the initial set of committers are all ASF members.
Therefore, we think that Apache will be an excellent home for Gora.
Initial Goals
Initial goals for Gora can be summarized as:
* Iron out the remaining issues with HBase, Cassandra and SQL support.
* Make the first release before the end of the year.
* Improve documentation
* Support for Cascading
Current Status
Meritocracy
Current commit rights belong to the initial list of committers four of who
are also ASF members. All the developers have extensive experience with
Apache projects. We honor the meritocracy policy of ASF foundation.
Community
Gora’s community mostly overlap with that of Nutch, Hadoop, HBase, Avro and
Cassandra. We have a small community for now (5 initial committers, 18
people tracking the project at Github), but have been piggybacking the Nutch
community for a while. If Gora is accepted to Apache Incubator, we expect
more traction. Moreover, with the increasing popularity of NoSQL databases,
we expect more users.
Core Developers
Gora was started by the initial code base inside Apache Nutch by Doğacan
Güney. Then Enis Söztutar has refactored and re-architected the project out
of Nutch. Later Julien Nioche, Andrzej Bialecki and Doğacan has ported Nutch
to use the newly formed project. Later, Sertan Alkan has joined. Doğacan and
Julien are Nutch PMC members, Andrzej is the Nutch PMC chair. Enis is an
Apache Hadoop PMC member.
Alignment
As discusssed in the second paragraph of Rationale Section, all of the
current developers are Apache people, and four of them are PMC members,
which shows that we have some experience with the Apache way. Moreover, Gora
is tightly related with lots of Apache projects, Nutch, Hadoop, HBase,
Cassandra, Avro, Pig, Hive, Lucene to name a few. Gora has started its life
inside Nutch, and now nutch trunk uses Gora to persist web crawl data to
HBase, Cassandra and MySQL, which means that Gora is a very critical
component in Nutch.
Known Risks
Orphaned Products
Most of the development depends on Enis and Doğacan for now. Both of them
intent to continue Gora development. However, we also acknowledge that more
core developers are needed for the project to be truly successful. The
general strategy to acquire more developers will be to acquire more users,
and encourage users to be active in the community and develop patches.
Moreover, the next release of Nutch planned before the end of 2010 has
extensive Gora support. We expect more interest from Nutch community, and we
will continue to announce Gora notifications at Hadoop,HBase and Cassandra
mailing lists.
Inexperience with Open Source
We believe that all of the developers have extensive open source experience.
Four of the initial committers are apache members. The codebase is also open
source since April 2010. We also have some documentation, wiki pages, issue
tracker and dev mailing list.
Homogeneous Developers
We have a semi-distributed development environment where Doğacan, Enis and
Sertan share the same office, but Andrzej and Julien are independent. With
the aim of acquiring more developers, we expect more heterogeneous
development.
Reliance on Salaried Developers
Gora development have been supported by ant.com
<http://wiki.apache.org/incubator/ant.com> search engine as contract work.
It is expected that this contract will continue in the future. However, even
without sponsors, we are commited to continue on Gora development, since we
believe in the technology it brings and it’s vital role in Nutch, and our
other closed sourced projects.
Relationships with Other Apache Products
Gora will be tightly related to lots of Apache projects:
*
* Nutch : Apache nutch was to home to Gora’s initial code base. Now, Nutch
trunk uses Gora as a library. The next relase of Nutch, planned before the
end of 2010 will be using Gora’s first release.
*
* Hadoop : Gora has extensive support for Hadoop MapReduce
<http://wiki.apache.org/incubator/MapReduce> Gora defines all the necessary
data structures for working with Hadoop .Data stored in column oriented data
stores can be analyzed with Gora using Hadoop.
*
* Avro : Gora uses and extends Avro. Data beans in Gora are defined using
Avro schemas ,and compiled into Java code with the extended version of the
Avro compiler. Avro is also used in data serialization.
*
* HBase : Gora supports HBase as a persistency backend.
*
* Cassandra : Gora support Cassandra as a persistency backend.
*
* Lucene/Solr : Gora intends to support Lucene/Solr as a persistency and
indexing backend.
*
* Pig : Gora intends to support Pig for data anaysis
*
* Hive : Gora intends to support Hive for data analysis
An Excessive Fascination with the Apache Brand
Gora is a natural fit for Apache due to it's current commiters and depending
projects.
Documentation
* The project is currently hosted at http://github.com/enis/gora/.

* Current web address: http://groups.google.com/group/gora-dev.
*
* Current email address: gora-dev@googlegroups.com.
Initial Source
The initial source was developed as a patch to the Apache Nutch project. But
the storage abstraction layer was orthogonal to the web crawler, and we
decided to extract it to a separate project with much wider goals. Thus
Gora, as a project, was born. The initial code is developed by Enis and
Dogacan with ant.com’s sponsorship.
The code can be found at http://github.com/enis/gora/.

> * The main use case for Gora is to access/analyze big data

> * Object-to-data store mappings are backend specific, so
