The Apache Software Foundation Announces the 5th Anniversary of Apache™ Cassandra™

Highest performing "NoSQL" distributed Big Data database in use at hundreds of organizations including Adobe, CERN, Comcast, Disney, eBay, GE, GitHub, GoDaddy, HP, Hulu, IBM, Instagram, Intuit, Netflix, Plaxo, Polyvore, Sony, and The Weather Channel

Forest Hill, MD –08 April 2014–
The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today the 5th Anniversary of Apache™ Cassandra™, the highly-performant Big Data distributed database.

"I am so proud to see what the Apache Cassandra community has been able to achieve in five short years," said Jonathan Ellis, Vice President of Apache Cassandra and DataStax CTO. "We've come such a long way since the early days, and it is a testament to Cassandra's rapid maturation that it has been deployed in over 1,500 global critical production environments."

Apache Cassandra is an Open Source, "NoSQL" distributed database management system designed to handle large amounts of data across many commodity servers quickly and reliably without compromising performance, whether running in the Cloud or in a hybrid data store. Cassandra offers robust support for clusters spanning multiple datacenters, and provides high availability with no single point of failure.

Originally developed at Facebook in 2008 to power their Inbox Search feature, Cassandra entered the Apache Incubator in 2009 and graduated as an Apache Top-level Project in February 2010.

Apache Cassandra has consistently led the NoSQL market in performance: its fully-distributed architecture provides unparalleled fault tolerance to ensure applications will not go offline, and its linear scalability allows them to reach massive sizes while successfully handling thousands of requests per second.

Cassandra Evolution 5 Years On: Under the Hood
During the past five years, Apache Cassandra has resolved over 6,000 JIRA issues and added more than 250 contributors, making today’s Cassandra significantly more performant, resilient, feature-complete, and easier to both operate and develop against. Some of the milestones along the way include:

The Cassandra Query Language, which offers a more intuitive data model and a performant native protocol while retaining backwards compatibility with data created under the old Apache Thrift API;
Lightweight transactions, an industry first that allows users and applications to opt into a linearly consistent world view as necessary;
An innovative virtual node design that allows expanding a cluster in increments as small as a single machine, and across heterogeneous hardware;
A powerful log-structured storage engine featuring advanced compaction, compression, and SSD support;
Thousands of enhancements from running the world's most demanding applications at scale, informing better performance, better drivers, and better management tools.


Improved Performance in Real-world Situations
Apache Cassandra powers hundreds of applications across dozens of industries that demand high performance at scale. By addressing the needs of different workloads, Cassandra has evolved beyond its initial niche in social media into a truly general purpose solution.

Apache Cassandra is used by many highly-visible organizations including: Adobe, Comcast, Disney, eBay, Eventbrite, GE, GoDaddy, HP, IBM, Instagram, Intuit, Netflix, Pearson, Safeway, Sky, Sony, Spotify, Travelocity, The Weather Channel, and Zoosk, among others. Additional organizations using Apache Cassandra can be found at http://planetcassandra.org/companies/

"We knew Apache Cassandra could perform linear scaling of reads and writes with consistent performance."
--David Weinstein, Director of Software Development, Adobe

"Before adopting Cassandra, we could not monitor every malicious site and IP forever – the data volumes were just too great. No other database was ready for what we needed to do."
--Michael Kjellman, Software Engineer, Barracuda Networks

"Apache Cassandra provides us with an easy to use backend and lets us focus on our implementation and features."
--Andreas Wagner, Lead Developer, CumulusRDF at the Karlsruhe Institute of Technology (KIT)

"Apache Cassandra is critical for being able to look up historical behavior data quickly, so that we can do these model updates with low latency."
--Thomas Pinckney, Senior Director of Engineering, eBay

"Apache Cassandra provides us an easy way of providing a highly available store and not have to worry about things like sharding, multi-datacenter support and things like that. Cassandra is an amazing store. Some of the features that you get out of the box are pretty incredible. I think one of the reasons why Cassandra has taken off and is doing so well is because of its awesome community."
--Vipul Sharma, Director of Data Engineering, Eventbrite 

"Apache Cassandra embodies in its core the resilience and availability we need to continue serving our enterprise and internal customers even in the face of transient outages. Most of the time we forget about Cassandra and it keeps on running."
--Michael Rose, Senior Platform Engineer, FullContact

 "The Google Cloud Platform was able to sustain one million Cassandra writes per second at a cost of $0.05 USD per million writes."
--Ivan Santa Maria Filho, Performance Engineering Lead, Google Cloud Performance Team

"Apache Cassandra offers good performance, near linear scalability for our data model, and geo-replication all with minimal maintenance requirements."
--Andres Rangel, Senior Software Engineer, Hulu

"We’re helping the world save water, which is a very laudable target for an innovative and commercial business. We’re using quite a lot of innovative technology to help us do that, of which Cassandra plays a major role."
--Mike Williams, Software Director, i2O Water

"At Instagram we've either replaced or are replacing every use case of Redis with Apache Cassandra. Its operational robustness and ability to exploit solid-state disks are the primary drivers for these efforts. We've also used Cassandra as part of major new feature efforts for its ability to scale up, scale down, and transparently work in a multi-region environment."
--Rick Branson, Infrastructure Software Engineer, Instagram

"The data was stored originally in Oracle in such a way that it does not scale at all … We chose Cassandra because of its ability to scale easily, the operational simplicity, but also because it met our requirements."
--DuyHai Doan, Senior Developer, Libon, a Division of Orange

"We absolutely love the data model and scalability that Cassandra offers us. Coupled with ease of use and the ability to get it up and running quickly in development means that we can experiment quickly and have code flow from development into production in a short amount of time."
--Hisham Mardam Bey, CTO, Mate1

"During Hurricane Sandy, we lost an entire data center. Completely. Lost. It. Our application fail-over resulted in us losing just a few moments of serving requests for a particular region of the country, but our data in Cassandra never went offline."
--Nathan Milford, US Operations Manager, Outbrain

"Portugal Telecom is now expanding to Brazil, which is a market that is roughly 25 times larger than ours, so we believe with the help of Cassandra we’ll store huge loads of information."
--Ivo Jesus, Tech Lead, Portugal Telecom

"We are the number one source for weather on all platforms: TV, web, mobile, and API.  Our digital group provides backend services across all our platforms —billions of requests per day— and is responsible for delivering scheduled and severe weather alerts. We make extensive use of Cassandra under the hood for our high-throughput use cases, and we support nearly every imaginable type of content.  We get about 100M transactions per day on average against our busiest Cassandra-backed service, with a heavy day seeing more like 180-200M transactions. Apache Cassandra has never failed us."
--Robbie Strickland, Software Development Manager, The Weather Channel

The Apache Software Foundation Announces Apache™ Olingo™ as a Top-Level Project

Open Source, generic Java client and server library implementation of the OData (Open Data Protocol) standard for interoperable querying and sharing of data across applications in enterprise, Cloud, and mobile environments

Forest Hill, MD –07 April 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that Apache™ Olingo™ has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.

"We are pleased to graduate from the Apache Incubator," said Stephan Klevenz, Vice President of Apache Olingo. "The Apache Way of collaborative software development shows that it is possible to produce high-quality and faithful implementations of standards." Klevenz is also a development architect at SAP and an Apache committer since 2010.

Apache Olingo provides generic Java and JavaScript libraries that implement the Open Data Protocol (OData), the standardized data access protocol used for creating and consuming data APIs in an interoperable manner across applications and devices. OData provides a uniform way to expose full-featured data APIs by building on core protocols such as HTTP as well as commonly accepted methodologies such as REST. 

Apache Olingo serves client and server aspects of OData 2.0, and will serve as a code base for OData 4.0, the OASIS standard of the protocol (OASIS OData TC). The OASIS international open standards consortium recently announced that Open Data Protocol (OData) version 4.0 and OData JavaScript Object Notation (JSON) Format version 4.0 have been approved as OASIS Standards. These REST-based standards simplify the querying, sharing, and consuming of data across applications for re-use in enterprise, Cloud, and mobile environments. More information on the OData ecosystem of open data producer and consumer services is available at http://www.OData.org/

Olingo is used by browser-based user interfaces to query data residing on servers. It is also used to synchronize data to mobile devices, and exchange data between server systems, and is part of the technical foundation of SAP NetWeaver® Gateway technology, among other enterprise solutions.

Olingo entered the Apache Incubator in July 2013, seeded by code from SAP (Java server libraries for OData 2.0) and Microsoft Open Technologies (Java client libraries for OData 3.0 and JavaScript libraries for OData 3.0). The project has since undergone three releases, reflecting 495,107 lines of code and 1,102 commits by 20 individual contributors.

Apache Olingo supports multiple languages, including Java and JavaScript for OData clients and servers, namely OData 2.0 in Java, OData 4.0 in Java, and OData 4.0 in JavaScript. Olingo extensions contain additional features, such as the support of Java Persistence API (JPA) or annotated bean classes. The project's documentation, wiki, and tutorials highlight several examples of implementing a custom OData service, including a sample Web application built with Apache Maven that can be deployed to any Java Platform, Enterprise Edition (JEE)-compliant Web application server, such as Apache Tomcat.

"OData v4 recently became an OASIS standard that is increasingly opening up data for an open Web," said Eduard Koller, Senior Program Manager at Microsoft Open Technologies, Inc. "Apache Olingo is open source software to aid in the production of OData v4.0 clients and servers in both Java and JavaScript. The project brings together several companies and community developers and we look forward to welcoming more users and contributors to the community."

The Apache Software Foundation Announces Apache™ Allura™ as a Top-Level Project

Open Source collaborative software development platform in use at DARPA, DLR German Aerospace Center, Open Source Projects Europe, and SourceForge, among others, to manage source code repositories, bug reports, discussions, wiki pages, blogs and more

Forest Hill, MD –01 April 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that Apache Allura has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.

Apache Allura is an Open Source, extensible, web-based platform that provides integrated software tools for collaborative software development. Initiated by SourceForge in 2009 to manage source code repositories, bug reports, discussions, wiki pages, blogs, and more for any number of individual projects, collection of projects or hierarchies of projects, the Allura forge was submitted to the Apache Incubator in June 2012. 

"The journey through the Apache Incubator made Allura a project for the community by the community," said Dave Brondsema, Vice President of Apache Allura. "I can't wait to see other Apache projects start using Allura, and hope to catch up with other Apache projects at the upcoming ApacheCon 2014 in Denver!"

"SourceForge has demonstrated their dedication to Open Source by putting their crown jewels into the custodianship of the Apache Software Foundation, and I'm excited to see where the project goes next as it embraces a larger community of users and developers," said Rich Bowen, Executive Vice President, Apache Software Foundation.

Apache Allura features include:
  • integrated issue tracking;
  • markdown formatting, including links to other artifacts (tickets, discussion/comments, commits, etc);
  • artifact subscriptions through mail and RSS;
  • a built-in discussion forum with a granular permission facility that allows for posts either via web or mail; 
  • a blog tool with threaded discussion; 
  • a code repository that hosts code with git, Mercurial, or Subversion with graphical representation formats

Allura allows for accelerated collaborative development across an array of user communities. Sites powered by Apache Allura include SourceForge, Open Source Projects Europe, DLR German Aerospace Center and DARPA's VehicleForge, among others.

"BerliOS recommends the SourceForge platform for migrating projects currently hosted on BerliOS. We value the fact that the SourceForge platform was first accepted as an Apache Incubator project and we are glad to see it now graduated," said Lutz Henckel, berliOS project leader. "This achievement means SourceForge platform --now known as Apache Allura-- is backed by a diverse and well-structured community. For projects hosted on SourceForge it also reduces the risk of vendor lock-in, as developing projects can get their data and software directly from the platform."

"Apache Allura is an Open Source modular forge platform using a scalable architecture and with well-known technologies around Python," says Alvaro del Castillo, Apache Allura committer and CTO of Bitergia. "It is easy to install and configure, a good bet for the future of collaborative software development around forges."

Apache Allura helps community members effectively manage any number of projects, including groups of projects known as neighborhoods, as well as sub-projects under individual projects. It has a modular design to support tools attached to neighborhoods or individual projects. The tools within Apache Allura were designed to support version control for source code repositories, ticket tracking, discussions, wiki pages, blogs and more. Additional external and third-party tools can be installed.

"We entered the Allura community to suggest the introduction of new functionalities to improve awareness of people and projects. We found that the community was open to our ideas," said Elisabetta Di Nitto, Associate professor of the University of Milan. "As a researcher I think this was a very interesting experience. We are glad we could influence the development of the forge and that the Allura community found our suggestions useful."

"SourceForge is very happy that Apache Allura, already used by 431,000 projects, will now be extended and available to an even wider developer community," said Gaurav Kuchhal, General Manager of SourceForge and Slashdot. "We stay committed to promoting open source projects by providing free marketing and global distribution, no matter where projects are developed."

Apache Allura is the result of an estimated 53 years of effort (as calculated by the COCOMO – Constructive Cost Model), with nearly 3,496 commits by 24 individual contributors (representing 208,417 lines of code).

The Apache Software Foundation Announces Apache™ Tajo™ as a Top-Level Project

Advanced Open Source data warehousing system in Apache Hadoop in use by Gruter, Korea University, and SK Telecom, among others, for processing Web-scale data sets

Forest Hill, MD –01 April 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that Apache Tajo has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.

"It's a pleasure to graduate from the Apache Incubator," said Hyunsik Choi, Vice President of Apache Tajo. "This milestone further reinforces our hard work in bringing a much-needed big data solution under the Apache banner."

Dubbed an "SQL-on-Hadoop" solution, Apache Tajo is a robust big data relational and distributed data warehouse system for Apache Hadoop. Tajo is designed for low-latency and scalable ad-hoc queries, online aggregation, and ETL (extract-transform-load process) on large-data sets stored on HDFS (Hadoop Distributed File System) and other data sources. By supporting SQL standards and leveraging advanced database techniques, Tajo allows direct control of distributed execution and data flow across a variety of query evaluation strategies and optimization opportunities.

The Tajo project began in 2010 at Korea University's Database Lab, and entered the Apache Incubator in March 2013. Apache Tajo is in use at Gruter, Korea University, and SK Telecom, among others, for its ability to analyze massive data sets in real time.

"Apache Tajo has earned its place as a top-level project in the ASF. It's an excellent example of a community building around a core piece of technology. Not to mention, the technology itself is quite cool. Tajo has a large role to play in the Apache Hadoop ecosystem," said Jakob Homan, Staff Software Engineer at LinkedIn, and ASF Member.

"Tajo project is a really good example that how company and Open Source community can benefit from each other. Its real open community has assisted me to solve lots of practical problems, and I have opportunities to make Tajo more robust and have richer functionalities," said Keuntae Park, IT manager of SK Telecom and contributor to Apache Tajo. "I feel much affection for Tajo project and it's my great pleasure to participate in its growth, graduation, and becoming of top-level project."

"Tajo is one of the most promising projects for SQL-on-Hadoop. Many contributors have been improving Tajo by developing various interesting features. It's an honor for me to work with such a wonderful community," said Jihoon Son, Ph.D. candidate at Korea University and contributor to Apache Tajo.

"Apache Tajo has been a model community through the Incubator. They have demonstrated meritocracy on lists in the face of some pretty awesome and complex software for Big Data Analytics," said Chris Mattmann, Apache Tajo Incubator Mentor at the ASF, and Chief Architect, Instrument and Science Data Systems Section at NASA JPL. "We are currently evaluating the use of Tajo in projects for Radio Astronomy at JPL, as well as in the context of our Airborne Snow Observatory (ASO) project for Big Data query processing and storage. I'm really excited to see where Tajo is headed along with the other Big Data stacks at the ASF including Spark and Mesos."

"The key to a successful Open Source community lies in its diversity and active participation," added Choi. "As Apache Tajo continues to grow, we welcome contributions with code, documentation, testing, submitting patches, and other valuable forms of feedback."

The Apache Software Foundation Announces Apache™ Open Climate Workbench™ as a Top-Level Project

Open Source analysis and evaluation toolkit initiated by UCLA and NASA/JPL's Regional Climate Model Evaluation System (RCMES) scientific collaboration; used in regional weather research and global climate dynamics modeling

Forest Hill, MD –03 March 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that the Apache Open Climate Workbench Project (a.k.a. "Apache Climate" or "Apache OCW") has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.

Apache Climate is a climate evaluation toolkit used to leverage model outputs from organizations such as the Earth System Grid Federation (ESGF), the Coordinated Regional Downscaling Experiment (CORDEX), the U.S. National Climate Assessment (NCA), and the North American Regional Climate Change Assessment Program (NARCCAP), coupled with remote sensing data from the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and other agencies.

"Collaboration and science go hand in hand so it's great to see NASA, CORDEX, NARCCAP, universities from around the world, and the greater climate science community embracing Open Source and the ASF," said Michael Joyce, Vice President of Apache Climate. "The Open Climate Workbench has had an amazing journey with a great team of contributors and I'm excited to see where it's going."

Originally seeded from the Regional Climate Model Evaluation System (RCMES) code from the Joint Institute for Regional Earth System Science and Engineering (JIFRESSE) scientific collaboration between University of California at Los Angeles (UCLA) and the NASA Jet Propulsion Laboratory (JPL), the Apache Climate toolkit includes capabilities for data rebinning, metrics computation, and visualization. RCMES now relies extensively on Apache Climate; those members of the global climate community who have been using RCMES prior to its submission to the Apache Incubator in February 2013 have advanced to using RCMES powered by Apache Open Climate Workbench.

Apache Climate features prominently in research applications, with the system used to analyze recent developments in United States and Africa, as well as examine the uncertainty in observed precipitation datasets over the India-Tibet region.

"The Indian Institute of Tropical Meteorology are the main the regional climate institution in India related with climate change and impact assessments for India and surrounding regions," explained Jinwon Kim, regional climate modeling lead scientist at JIFRESSE and researcher at the UCLA Department of Atmospheric and Oceanic Sciences.

"I am using components of Apache OCW in my research to build an application that can identify weather-scaled phenomenon in long-term high resolution satellite (and eventually climate model) datasets," said Kim Whitehall, PhD student in the Howard University Program in Atmospheric Sciences (HUPAS).

Apache Climate is the result of an estimated 24 years of effort (as calculated by the COCOMO – Constructive Cost Model), with nearly 850 commits by 15 individual contributors (representing 94,843 lines of code) during its first year at The Apache Software Foundation.

To manage the massive datasets associated with the metrics, visualizations, and algorithms that support RCMES, Apache Climate is often paired with Apache OODT™ (Object Oriented Data Technology), the Open Source data management system framework originally developed at NASA for information integration and for science data processing and retrieval.

"Leveraging Apache OODT, which was reused on SNPP (Suomi National Polar-Orbiting Partnership) and JPSS (Joint Polar Satellite System) satellite missions, and the Apache open source governance, the OCW is the next step in the development of an integrated climate community research and development environment," explained Dr. Tsengdar Lee, Scientific Computing Portfolio Manager and Weather Data Analysis Program Scientist at the NASA Science Mission Directorate. "It will be developed by the community for the community in a completely open way."

"The community is always looking for good tools to analysis massive amounts of distributed data. It looks like Apache Climate can help in that effort," said Dean Williams, Analytics and Informatics Management Systems project leader at the Lawrence Livermore National Laboratory (LLNL) and Principal Investigator of the Earth System Grid Federation.

A demonstration of RCMES powered by Apache Climate is available at http://rcmes.jpl.nasa.gov/training/videos

The Apache Software Foundation Announces Apache™ Spark™ as a Top-Level Project

Super-fast, Open Source large-scale data processing and advanced analytics engine in use at Alibaba, Cloudera, Databricks, IBM, Intel, and Yahoo, among others

Forest Hill, MD –27 February 2014– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that Apache Spark has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.

Apache Spark is an Open Source cluster computing framework for fast and flexible large-scale data analysis. Dubbed a "Hadoop Swiss Army knife" by The Register, Spark is recognized for its remarkable speed and ease of use, running programs up to 100x faster than Apache Hadoop MapReduce in memory, and with APIs that allow developers to quickly write applications in Java, Python, or Scala.

"It's great to see Apache become Spark’s permanent home," said Matei Zaharia, Vice President of Apache Spark. "Spark has quickly become one of the most active projects in the Hadoop ecosystem, with dozens of organizations contributing, and we look forward to working closely with the rest of the Apache community."

Initially created in 2009 at the University of California at Berkeley's AMPLab (the research center also responsible for the original development of Apache Mesos), the Spark distributed computing framework for advanced analytics in Apache Hadoop can easily be used standalone or on Hadoop YARN, EC2 or Mesos. Integrated with Apache Hadoop, Spark is well suited for machine learning,  interactive queries, and stream processing, and can read from HDFS, HBase, Cassandra, as well as any Hadoop data source.

"This is a major milestone for the students and researchers in the AMPLab," said Mike Franklin, Director of the AMPLab at UC Berkeley. "Spark demonstrates the real impact that research can have and validates the support AMPLab has received from our White House-announced NSF Expeditions in Computing Award and our 20+ industrial sponsors and collaborators."

"Through our work on Spark at both AMPLab and Databricks, we’ve focused on making it much easier for organizations to get insights from big data," said Ion Stoica, CEO at Databricks and Professor at UC Berkeley. "We're doing this together with a fantastic open source community. We look forward to continue working with the community to accelerate the development and adoption of Apache Spark."

Since entering the Apache Incubator in June 2013, Apache Spark bolstered its community through code contributions by more than 120 developers from 25 organizations. Apache Spark is in use at an array of global corporations that include Alibaba, Cloudera, Databricks, IBM, Intel, and Yahoo, among others.

Andrew Feng, Distinguished Architect at Yahoo, said "Yahoo has played a leading role in evolving Hadoop and related big-data technologies, including Spark. While Apache Hadoop serves as the foundation of our big-data platform, Spark is an attractive technology for iterative applications such as machine learning. Yahoo has made significant contributions to the development of Spark and we congratulate Spark on becoming an Apache top-level project."

"I'm really proud of the community aspect that has become infectious in Apache Spark and that really grew out of the energy in the project starting in the AMP Lab and through its movement to the ASF," said Chris Mattmann, Apache Spark Incubator Mentor at the ASF, and Chief Architect, Instrument and Science Data Systems Section at NASA JPL. "Matei, Patrick, Reynold, and many of the leaders of the project have really done a tremendous job and I'm excited to see the next generation of Hadoop-style systems have a home at the ASF."

"We have some very exciting features coming in the next months, so stay tuned for even more powerful versions of Spark," added Zaharia.

The ASF asks: Have you met Apache™ Marmotta™?

The all-volunteer Apache Software Foundation (ASF) develops, stewards, and incubates over 200 Open Source projects and initiatives, many of which power mission-critical applications in financial services, aerospace, publishing, big data, government, healthcare, research, infrastructure, and more.

Did you know that 50% of the Top 10 downloaded Open Source products are Apache projects? Did you know that one of the ASF's most active projects is Apache Marmotta?

Quick peek: Apache Marmotta is an Open Platform for Linked Data, a paradigm promoted by the World Wide Web Consortium (W3C) for large scale data integration across the Web based the RDF technology stack.

Background: Initiated in 2008 by a group of researchers from Salzburg Research as the EU-funded KiWi project (investigated the idea of "Semantic Wikis" and aimed at combining easily editable Web content with Semantic Web technologies to provide data to both human and machine users), later refocused and renamed as LMF. The project was contributed as "Marmotta" to the Apache Incubator in December of 2012. Apache Marmotta graduated as an Apache Top-Level Project in November 2013.

A history of the project is available at http://redlink.co/apache-marmotta/ and http://www.salzburgresearch.at/en/2013/apache-marmotta-graduated-top-level-project/ .

Why Marmotta: Apache Marmotta was created to provide an Open Source implementation of Linked Data technologies in general, and Linked Data Platform in particular. Usually organizations who want to use this technology need to assemble together different pieces of software, with the obvious problems derived, both technical and legal. Apache Marmotta satisfies that need of the industry, supporting almost any use-case with a permissive Open Source license.

Apache Marmotta powers Salzburger Nachrichten's search and archive, the Open Data portal at Enel, as well as Redlink's cloud infrastructure, among other implementations.


What's under the hood: Apache Marmotta includes features that make easier building Linked Data applications, including: full Read-Write Linked Data with basic security mechanism, exchangeable RDF triple stores, SPARQL and LDPath languages for querying, transparent Linked Data caching and an extensible modules architecture where you can plug-in your own modules.

Apache Marmotta comprises the following components:

  • The Marmotta Platform, a JavaEE web application providing the Linked Data server;
  • KiWi, a Sesame-based triple store built on top of a relational database, including reasoning and versioning;
  • LDPath, a path language to navigate across Linked Data resources;
  • LDClient, a client that allows retrieval of remote legacy resources not available as Linked Data; and
  • LDCache, a cache system that automatically retrieves resources by internally using LDClient

Latest release: Apache Marmotta v3.1.0-incubating on 13 October 2012 under the Apache License v.2.0. More details can be found in the Release Notes.

In the upcoming weeks the Project plans to release its next version --the first one as on official Apache Top-Level Project. Stay tuned via the Apache Marmotta developer, user, and commit lists at http://marmotta.apache.org/mail-lists.html

The ASF's Position on Oracle's TCK License

In December 2010, The Apache Software Foundation resigned its seat on the JCP Executive Committee. Since then, our access to TCKs that previously had been provided by Oracle to a number of ASF projects has expired.

The ASF has not blocked its projects from having access to JCP-provided TCKs. A number of such TCKs are made available without conditions that affect our ability to release our software under the terms of the Apache License, Version 2.0; for example, the JSR303 Bean Validation TCK was created by Red Hat/JBoss and is available under the Apache License, version 2.0.

This is not the case with a number of TCKs provided by Oracle.

ASF's position has always been that it would license Java TCKs only if it could do so without incurring any restriction that was incompatible with its license and open source software development and distribution practices. Sun Microsystems originally encouraged ASF to join the Java Community Process Executive Committee with the promise that ASF would have the opportunity to help define the Java Specification Participation Agreement and ensure that it included no such restrictions. Progress was slow, and ASF nearly abandoned the JCP in 2002, but eventually Sun agreed -- in a side-letter modifying the TCK License Agreements -- that the restrictions of concern to ASF would be construed so as not to restrict independent open source implementations:

http://jakarta.apache.org/site/sideletter.pdf

Additionally, the JSPA was modified to 1) prevent the specification lead (then Sun, now Oracle) from restricting the development or distribution of independent implementations and 2) require the specification lead to license essential IP royalty-free to any spec-compatible implementations. With these provisions in place, ASF was comfortable that the TCK licenses and JSPA were compatible with its development processes.

Unfortunately, Sun breached the JSPA in 2006 by licensing the Java SE Compatibility Kit under terms inconsistent with its prior representations to ASF and its obligations under the JSPA, and incompatible with ASF's development of Apache Harmony. ASF urged Sun to honor its agreements, but after Sun persisted in its breach for a year, ASF withdrew from the JCP. At the time, Oracle supported ASF's position that Sun was in breach of the JSPA. But after acquiring Sun, Oracle adopted Sun's policy, disregarding the limits of the JSPA that formed the basis for ASF's participation in the JSP and acceptance of the various TCK licenses.

ASF's position has not changed -- it cannot accept restrictions on TCK-tested code that are incompatible with its license and open source development practices. An example is the requirement in Section 2.1(b)(v) of the Stand-Alone TCK License Agreement, that any software tested with the TCK must thereafter be updated to comply with every subsequent version of the corresponding specification published by Oracle. This provision has always been a part of the TCK License Agreement, but was previously relaxed by an agreement with Oracle's predecessor upon which ASF no longer feels it can rely.

Thus, ASF can only agree to the TCK license if Oracle will amend it consistent with the 2002 side-letter referred to above -- i.e. by removing or reconstruing restrictions that are incompatible with ASF's licensing and development practices -- and to make available under these terms all of the TCKs Apache has previously had access to. We would be eager to work with Oracle on these revisions.

The Apache Software Foundation Announces Apache™ Hadoop™ 2

Foundation of next-generation Open Source Big Data Cloud computing platform runs multiple applications simultaneously to enable users to quickly and efficiently leverage data in multiple ways at supercomputing speed.

Forest Hill, MD –16 October 2013– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache™ Hadoop™ 2, the latest version of the Open Source software framework for reliable, scalable, distributed computing.

A foundation of Cloud computing and at the epicenter of "big data" solutions, Apache Hadoop enables data-intensive distributed applications to work with thousands of nodes and exabytes of data. Hadoop enables organizations to more efficiently and cost-effectively store, process, manage and analyze the growing volumes of data being created and collected every day. Apache Hadoop connects thousands of servers to process and analyze data at supercomputing speed.

The project's latest release marks a major milestone more than four years in the making, and has achieved the level of stability and enterprise-readiness to earn the General Availability designation. 

"With the release of stable Hadoop 2, the community celebrates not only an iteration of the software, but an inflection point in the project's development. We believe this platform is capable of supporting new applications and research in large-scale, commodity computing," said Apache Hadoop Vice President Chris Douglas. "The Apache Software Foundation creates the conditions for innovative, community-driven technology like Hadoop to evolve. When that process converges, the result is inspiring."

"Hadoop 2 marks a major evolution of the open source project that has been built collectively by passionate and dedicated developers and committers in the Apache community who are committed to bringing greater usability and stability to the data platform," said Arun C. Murthy, release manager of Apache Hadoop 2 and Founder of Hortonworks Inc. "It has been an honor and pleasure to work with the community and a personal thrill to see our four years of work on YARN finally coming to fruition in the GA of Hadoop 2.  Hadoop is truly becoming a cornerstone of the modern data architecture by enabling organizations to leverage the value of all their data, including capturing net-new data types, to drive innovative new services and applications."

"What started out a few years ago as a scalable batch processing system for Java programmers has now emerged as the kernel of the operating system for big data," said original Hadoop creator and ASF Board member Doug Cutting. "Over a dozen Apache projects integrate with Hadoop, with ten more in the Apache Incubator poised to soon join their ranks."

Dubbed a "Swiss army knife of the 21st century" and named "Innovation of the Year" by the 2011 Media Guardian Innovation Awards, Apache Hadoop is widely deployed at enterprise organizations around the globe, including industry leaders from across the Internet and social networking landscape such as Amazon Web Services, AOL, Apple, eBay, Facebook, foursquare, HP, LinkedIn, Netflix, The New York Times, Rackspace, and Twitter. Other technology leaders such as Microsoft, IBM, Teradata, SAP have integrated Apache Hadoop into their offerings. Yahoo!, an early pioneer, hosts the world’s largest known Hadoop production environment to date, spanning more than 35,000 nodes.

Under the Hood
Apache Hadoop 2 reflects intensive community- development, production experience, extensive testing, and feedback from hundreds of knowledgeable users, data scientists and systems engineers, bringing a highly stable, enterprise-ready release of the fastest-growing big data platform. 

New in Hadoop 2 is the addition of YARN that sits on top of HDFS and serves as a large-scale, distributed operating system for big data applications, enabling multiple applications to run simultaneously for more efficient support of data throughout its entire lifecycle. The culmination of so many other releases in the Hadoop 2.x line, the most current release --2.2.0-- is the first stable release in the 2.x line. Features include support support for:
  • Apache Hadoop YARN, a cornerstone of next generation Apache Hadoop, for running both data-processing applications (e.g. Apache Hadoop MapReduce, Apache Storm etc.) and services (e.g. Apache HBase)
  • High Availability for Apache Hadoop HDFS
  • Federation for Apache Hadoop HDFS for significant scale compared to Apache Hadoop 1.x.
  • Binary Compatibility for existing Apache Hadoop MapReduce applications built for Apache Hadoop 1.x. 
  • Support for Microsoft Windows. 
  • Snapshots for data in Apache Hadoop HDFS. 
  • NFS-v3 Access for Apache Hadoop HDFS. 

"The community has stepped up to the challenge of making Hadoop enterprise-ready, hardening the filesystem, providing high availability, adding critical security capabilities,and delivering integrations to enable consolidation of any kind or amount of enterprise data," said Aaron Myers, member of the Apache Hadoop Project Management Committee and Engineer at Cloudera.

"Today, with the announcement of Hadoop 2 and YARN, we've taken another step. Beyond the basic multitenancy customers have enjoyed for the past year, enabling them to mix batch, interactive and real-time workloads, they now have the ability to do so from within a stable foundational part of the Hadoop ecosystem. It's a testament to the community's work that now every distribution of Apache Hadoop will enjoy these benefits, ensuring that customers can deliver the applications they need, on a single Hadoop platform."

"It has been an honor and pleasure to work with the community and a personal thrill to see our four years of work on YARN finally coming to fruition in the GA of Hadoop 2," added Murthy. "Apache Hadoop is truly becoming a cornerstone of the modern data architecture by enabling organizations to leverage the value of all their data, including capturing net-new data types, to drive innovative new services and applications."

"A large portion of the credit for this success is due to Apache's open-source model, which has permitted a wide range of users and vendors to productively collaborate on a platform shared by all," added Cutting.

The Apache Software Foundation Announces Apache™ Cassandra™ v2.0

Highly-performant, Open Source Big Data distributed database in use at Adobe, CERN, Comcast, eBay, GoDaddy, HP, IBM, Instagram, Netflix, Plaxo, and Sony, among others, to create modern, data-driven applications

Forest Hill, MD –4 September 2013– The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache Cassandra v2.0, the latest version of the highly-scalable, Big Data distributed database.

Apache Cassandra powers massive data sets quickly and reliably without compromising performance, whether running in the Cloud or partially on-premise in a hybrid data store. Its fully distributed architecture provides unparalleled fault tolerance to ensure applications will not go offline, and its linear scalability allows them to reach massive sizes while successfully handling thousands of requests per second.

"In five years, Apache Cassandra has grown into one of the most widely used NoSQL databases in the world and serves as the backbone for some of today’s most popular applications," said Jonathan Ellis, Vice President of Apache Cassandra.

Under the Hood

New features in Apache Cassandra v2.0 include lightweight transactions, triggers, and CQL (Cassandra Query Language) enhancements that increase productivity in creating modern, data-driven applications.

"Cassandra 2.0 makes it easier than ever for developers to migrate from relational databases and become productive quickly," added Ellis.

New features and improvements include:

  • Lightweight transactions allow ensuring operation linearizability similar to the serializable isolation level offered by relational databases, which prevents conflicts during concurrent requests
  • Triggers, which enable pushing performance-critical code close to the data it deals with, and simplify integration with event-driven frameworks like Storm
  • CQL enhancements such as cursors and improved index support
  • Improved compaction, keeping read performance from deteriorating under heavy write load
  • Eager retries to avoid query timeouts by sending redundant requests to other replicas if too much time elapses on the original request
  • Custom Thrift server implementation based on LMAX Disruptor that achieves lower message processing latencies and better throughput with flexible buffer allocation strategies
Strong Community Engagement and Adoption

The Apache Cassandra developer community includes some of the brightest minds in Big Data. Hundreds of organizations, from startups to large-scale enterprises such as Adobe, Cisco and IBM, rely on Cassandra to power their mission-critical applications online.

"At Ooyala, we're building some of our most ambitious projects to date on top of Apache Cassandra," said Al Tobey, Tech Lead, Compute and Data Services, Ooyala. "The maturation of CQL3, vnodes, and new features such as the PAXOS-backed compare-and-set (CAS) added in Cassandra 2.0 will help us build and deploy those projects confidently."

Apache Cassandra is used by many highly-visible organizations such as Accenture, CERN, Cloudkick, Comcast, Constant Contact, Dell, Digg, Ericsson, Eventbrite, GoDaddy, Houghton Mifflin Harcourt, HP, Instagram, Intuit, Mahalo, Microsoft MetricsHub, Morningstar, NASA, Netflix, Nextag, OpenWave, PBS Kids, Pitney Bowes, Plaxo, Polyvore, Real Networks, Reddit, Sony Network Entertainment, SoundCloud, Spotify, Squidoo, Stormpath, Symantec, Twitter, Wildfire, WSO2, and ZoomInfo. A listing of where Apache Cassandra is used and deployment details can be found at http://planetcassandra.org/Company/ViewCompany?IndustryId=-1

"We are excited about the future Apache Cassandra 2.0 makes possible. Paying down a lot of the technical debt accumulated over 5 years of intense Open Source development, and solidifying the Native Binary Transport for CQL 3, has put the project on a great footing," said Aaron Morton, Apache Cassandra committer and Co-Founder & Principal Consultant of The Last Pickle. "The addition of Lightweight 'Compare-and-Set' Transactions and Cursors brings another set of features that make it easier for developers to harness the performance and scale of Cassandra. And the experimental Trigger support will allow Open Source contributors to provide feedback for this often requested feature."

"It'll be really helpful to have conditional updates built into Cassandra," explained Jon Haddad, Senior Architect at Shift. "Right now there's a few places where we have to use external locking to manage isolation, and having built in support in the database will be amazing."

"We feel this release will delight existing users and tempt those on the sidelines," added Morton.

The Apache Software Foundation Announces Apache™ Mesos™ as a Top-Level Project

Powerful Open Source cluster manager in use at Airbnb, Twitter, and the University of California, among others, for dynamic resource sharing across cluster applications

24 July 2013 --Forest Hill, MD-- The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, announced today that Apache Mesos has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project's community and products have been well-governed under the ASF's meritocratic process and principles.

Apache Mesos is a cluster manager that provides efficient resource isolation and sharing across distributed applications, or frameworks. It can run multiple frameworks, including Apache Hadoop, MPI, Hypertable, Jenkins, Storm, and Spark, as well as other applications and custom frameworks.

"It was our goal all along to see Mesos become a kernel of the infrastructure stack of the future," said Benjamin Hindman, Vice President of Apache Mesos. "The project’s graduation from the Apache Incubator is recognition that the software is mature and has brought together a diverse community to sustain it in the future."

Initially created at the University of California at Berkeley's AMPLab (the research center also responsible for the original development of Apache Spark) to manage resource sharing and isolation in data centers, Mesos acts as a layer of abstraction between applications and pools of servers. Mesos helps avoid the necessity of creating separate clusters to run individual frameworks and instead making it possible to optimize how jobs are executed across shared machines.

Whilst in the Apache Incubator, Mesos had four releases, and established an Open Source community according to The Apache Way of governance. Additional improvements to the project includes its flexibility to support several application framework languages, and scalability that has been production tested to thousands of nodes and simulated to tens of thousands of nodes and hundreds of frameworks.

Apache Mesos has proven to be reliable for use in production, and has already been adopted by several organizations for cluster management.

"Mesos is the cornerstone of our elastic compute infrastructure," explained Chris Fry, Senior Vice President of Engineering at Twitter. "It's how we build all our new services and is critical for Twitter's continued success at scale … one of the primary keys to our data infrastructure efficiency."

"We're using Mesos to manage cluster resources for most of our data infrastructure," said Brenden Matthews, Engineer at Airbnb and Apache Mesos Committer. "We run Chronos, Storm, and Hadoop on top of Mesos in order to process petabytes of data." (Chronos is an Airbnb-developed Mesos framework as a replacement for cron, and an example of how custom frameworks can be developed on Mesos to leverage its resource sharing).

"Community support for Apache Mesos is encouraging, particularly as more companies assess how they manage their clusters and look for more efficiency," added Hindman. "Now that we've graduated, we look forward to continuing to grow the number of Mesos adopters and fostering an ecosystem around the project."
